[TUT] Revert OTA 3.2 back to 3.0.1

Well as long as we have ICS OTA this thread seems to be less needed. Anyway, I'll leave it this way in case someone is stuck on HC 3.2 without root and without being able to update to ICS. How to get root on your stock ICS, look here or here
__________________________________________________
If you’re reading this may be you’re stuck with a 3.2 OTA update without ROOT privileges on your A500. This tutorial explains how to revert your OTA 3.2 to 3.0.1. Original article for those of you who speak Russian here
Thanks to begemot666.
These methods could be used to unbrick your device i.e. when boot.img and recovery.img are corrupt.
METHOD 1 - thanks, vache
It is best to use a PC with Windows 7 on it. Most of the problems reported seem to be XP related.
1. Download and unpack the archive provided by vache here - for Firefox rightclick and select "Save link as".
MIRROR
2. Get your UID (without it nothing is going to work). How to do that – read sc2k’s itsmagic thread. Enable USB debugging on the tablet.
3. Edit the file CPUID inside the extracted folder with a text editor - you have to change this line with your UID number but you need to add “zeroxzero” in front of it, example: if your UID is 37c7040425ff0d7, at the end it needs to look like 0x037c7040425ff0d7.
Save the file.
4. Connect your tablet with the PC.
5. Run PBJ20upgrade.exe as administrator and follow app instructions. USB drivers are provided with this archive and the app installs them automatically according to your system.
6. After driver installation the app scans your tablet and it will show version number of your current firmware and version number of the firmware that is going to be applied after restoration. Follow all application instructions. Tablet will switch to APX mode with ACER logo on its screen and on your PC you’ll see the progress bar of the process. Before the beginning of the flashing process the app will ask you for identification number. Here you enter your UID which you have placed in the CPUID file with a zero infront. Example: 037c7040425ff0d7
Below are screenshots from the EUU app that's used to downgrade to 3.0.1
The whole things takes 10 or more minutes so be patient. Then you’ll have HC 3.0.1
All data on your system and data partitions will be lost. Storage will remain intact.
7. Once on Honeycomb 3.0.1, install Iconiaroot 1.3, root your tab and then install CWM from thor's site (there you can find the latest version) or use Acer Recovery Installer from the Market, or look at the original thread here
8. Boot into CWM and flash whatever ROM you like!
METHOD 1 update: You can use timmyDean 's modified and tweaked EUU tool that will flash directly a rooted stock 3.2.1 ROM:
http://forum.xda-developers.com/showthread.php?t=1307539
METHOD 2 - thanks GamezR2EZ
This is even easier because it does not need your UID. It is just flashing as a normal update but actually it is an older HC version that is rootable by Iconiaroot. Additionally method 2 leaves your data intact and you will be able to backup your apps after downgrading with tools like Titanium Backup. Thanks heldc for pointing this out.
1. Download this package (named "downgrade not stable"). mirror1 mirror2 mirror3
2. Extract the update.zip from it and place it on your external SD card.
3. Turn off your tab and then turn it back on while holding Volume Down key. This will automatically flash the update.zip from your SD card.
4. After flashing is finished you'll have unstable Honeycomb 3.0.1 - gives errors and crashes but you only need it to root and install CWM. If it fails to boot try to hard reset your device *.
5. Install Iconiaroot 1.3, root your tab and then install CWM from thor's site (there you can find the latest version) or use Acer Recovery Installer from the Market, or look at the original thread here
6. Boot into CWM and flash whatever ROM you like!
GOOD LUCK !
* How to hard reset your Iconia A500
1. Turn off your tablet
2. Place the screen lock button on the left (red not visible)
3. Hold Volume UP + Power button
4. After the vibration, release the power button and toggle the screen switch few times left-right until you see the following lines appear on the screen
Erasing Userdata...
Erasing Cache...
You can now release Volume UP button.
5. In the top left corner you'll see formatting has started.
6. Tablet will reboot

downgrade from stock 3.2 now possible ...all right !!!!
Thank you so very much.... it worked for me ... kudos kudos ....

Have no idea, my friend, check again all the steps and if the usb drivers are properly installed.

Maybe it could help : EUUs_SBK_Acer_A500_1.016.05_COM_GEN1
You can post it in 4PDA.ru.

A little guidance please.
Will try this at home.
edit:
I'm following what says on c2k’s itsmagic thread and ran the batch file (01_backup.bat) but my tablet is not rooted.
Using the manual method in getting my UID, how to execute the "dd"?
Manual method:
1. Get your UID (= USB Serial number, has up to 16 chars) (see at the end of this post how to get). If you brick your device and do not know the UID, you are lost.
2. Backup all partitions (except cache + data) with dd:

I apologize for the stupid question, but it's better to be sure before doing something wrong.
I have an A501, I suppose this procedure is still valid, but I have to skip the point where the product name is changed from A501 to A500.
It's correct?
thanks

I've exactly the same problem, with the 2 methods...
Edit : I finally found the solution : if the program says "UID is incorrect", you must add a 0 (zero) in front of it - for example, if your UID is 280404412345678, you must write 0280404412345678 - and it works perfectly !
Thank your very much !!!

I wonder if one of the devs on here who are smarter than myself could investigate this further and maybe figure out enough from it to come up with a root exploit for 3.2? (seems like it manages to bypass the security of the bootloader to go back to 3.0.1, so it seems logical the same exploit could be used for a direct, and possibly simple, root?)

Appears that you have to put a 0 in front of your UID in the last step (wasn't listed in the tutorial, but their example shows it)
On a side note, I've done that, and it claims to be doing the upgrade, but my tablet screen went completely blank (tutorial says it should have the acer logo) and the progress bar is also blank (not moving at all in 10 minutes now)... not entirely sure what's happening, but I have a feeling not much is working right...

The 2nd method worked for me. FYI if you've ever backed up your rom with CWM your UID is in a txt file in the folder of the backed up ROM. Just omit the 0x at the beggining of this file and copy and paste that when it asks you to enter your UID but use the whole UID you find in this file when copying it into the CPUID.txt file THANKS SO MUCH!!! Im now on 3.01 and ready to root/flash this sucker back to my backed up ROM>

I have now tried both methods without any success
Method 1 can't see the tablet, it tells me to do a pin-hole reset and click "yes"... but that just takes me back to the same slide.
Method 2 gets all the way to flashing the image, however the status bar never moves (have left it for 2 hours) and the tablet just sits at a blank screen (not the acer logo as the tutorial says)
I tried reflashing the stock rom, factory resetting, clearing the cache, and trying again, all with exactly the same results.
I'm still stuck on stock, unrooted, 3.2
And the worst thing is, with so many people having success with this, it's likely to become the "official" way of rooting 3.2, leaving nobody any incentive to find another way, and me stuck without root

My screen also went completely blank but it still worked and booted into the Acer logo when it was copying the ROM to the tablet with a message of "entering download mode" or something like that in the upper right corner. Once it was done flashing it had in bock ASCII art letters "OK" above the acer logo and then rebooted.

I'm guessing that it didn't take over 2 hours, and that you had a status bar on the computer doing something though...

[GUIDE] TF300T Unlock/Root/Flash for Factory JB Devices on 4.1.X (newbie friendly)

Having recently purchased a TF300T with intent to customize the hell out of it, I ran into a big problem. There wasn't one definitive guide for my general case, some of the steps I read weren't completely clear, and I often had to put pieces together from multiple guides to get where I wanted. Halfway through the process it occurred to me that sharing my experience in form of a guide could give the community something I wish that I had when I began. So enough with the intro, let's visualize the process before we begin.
This guide is for new owners of TF300T devices that have Jelly Bean 4.1.X preflashed from the factory. ​

If your tablet has 4.2.1 Android version from Asus, DO NOT FLASH A RECOVERY THAT WAS ACTUALLY MADE FOR 4.1 TABLETS! You will end up on a PERMANENT BRICK with no solution until now. You won't be able to use fastboot ever again. You won't be able to flash anything ever again. You will be stuck with a bricked tablet!
If you are looking for a Recovery for a 4.2.1 bootloader (and a complete guide for updating), read this thread: http://forum.xda-developers.com/showthread.php?t=2187982 Don't do it with any other tutorial: they are for 4.1 bootloaders!

For those curious...
My TF300T was one of the Champagne Gold models purchased from Groupon with a serial that begins with C9. I recall seeing a user with a Champagne Gold from Amazon that still had ICS. If you're still on ICS, this guide isn't for you-- Read up on NVflash and decide if you want to take advantage of it BEFORE you upgrade to JB.
Here's an overview of what we will be doing:

Unlock the TF300T
Backup apps, app data and files (Recommended, Optional)
Install ClockworkMod Recovery (soon to be replaced with TWRP; I gave in)
Root the TF300T (Optional)
Backup your stock Asus ROM (Recommended, Optional)
Flash a Custom ROM
Backup your working Custom ROM (Optional)

This guide has been made with the total android noob in mind. Having only owned an android tablet for a week, I too am an android noob. On the flipside, I'm no noob to hardware and software exploits and modifications. I've tried to make this friendly for any type of noob, but there are a few instances where I expect basic menu and Windows 7 navigation skills.
ClockworkMod Recovery doesn't appear to have a "Shutdown" function, nor does it display current battery level-- for this reason, the recommendation and warning to have a battery charged to at least 60% is extremely heavy. The worst thing that can happen to any device is usually an incomplete flash. Don't let it happen to you-- start charging your TF300T NOW.
I have seen reports that "Fastboot" doesn't work properly on Windows 7 64-bit. This guide addresses that issue, as I also encountered it. If you don't know what "Fastboot" is, in the words of an admirable comedian, "You gonna learn today". Don't worry about it for now!
Your device came with JB-- you didn't miss the bus for NVflash. In your case, the bus never came.
I am not responsible for any damages caused to (but not limited to) yourself or your device.
Even if you think you're pretty good at figuring this stuff out, stick to the directions as close as possible.
If you love tweaks, you're going to love your custom ROMs.
Let's get started!
Unlocking Your TF300T
Click to expand...
Click to collapse
WARNING: Unlocking your TF300T will void your warranty. If your device breaks or fails under normal use, don't expect Asus to pick up the tab! Be aware that once unlocked, it cannot be relocked.
There are two ways you can go about this-- Either download the official Asus unlock utility for Windows or download the .apk and install from your tablet (Asus utility still working! I successfully unlocked mine on JB 4.1.1). I chose to download the .apk and install directly on my tablet, therefore this is the method I will cover.
To download the .apk file, scan the QR Code below with Barcode Scanner (free; on Play store) and open the URL to the Asus Support page for the TF300T. Alternatively, if you are viewing this thread on your TF300T, you may simply tap the code below.
​
On the Asus Support page, select "Android" as your OS. The page will reload and present you with a list. Click on "Utilities", then after it has loaded, download the Unlock Device App. When it is done downloading, a notification will pop up in the lower right corner. Click on it to install the Unlock tool. You'll also be able to open the app immediately after the install completes-- open it now.
After scrolling to the bottom of the End User Licence Agreement, select the checkbox indicating that you agree to those terms. You should now have access to the slider that will unlock your tablet. Stay connected to your wifi and unlock when ready. The unlock will not work without access to the internet.
If I recall correctly, your tablet should reboot. Just let it do what it wants. After it's done doing it's thing, take this opportunity to make backups! when you and your tablet are ready, we'll continue on to the next step.
Setting Up The Android SDK and Installing ClockworkMod Recovery
Click to expand...
Click to collapse
​Perhaps this was the most frustrating part of my experience-- Installing the Android SDK went fine when I could actually find the .exe download. After that it was a matter of getting the drivers for Fastboot working properly. I was able to narrow it down to a problem for users of Windows 7 64-bit.
From your PC, go HERE, scroll down and click on "Download For Other Platforms". Scroll down more and under the "SDK Tools Only" downloads, you should find a download that looks like: "installer_r##-windows.exe" where "##" is the revision number. Download this .exe and assuming Windows is installed on C:\, install it to either "C:\tools\android-sdk" or "C:\android-sdk". If Windows is not installed to drive letter C, replace the drive letter with the correct letter for your system. Do the same when following the command prompt examples that follow.
Open the Android SDK Manager. Search for "SDK Manager" in the start menu and you should find a result with the same name and a little android icon. Once it's open, you'll be presented with a list. Check the box next to the "Tools" folder, then expand the "Extras" folder and check the box next to "Google USB Driver". In the lower right corner, click "Install packages...", agree to all when ready and begin your downloads.
In the settings application of your tablet, go to the "Developer options" tab near the bottom. Ensure that the switch in the top right corner is in the "ON" position, then under the "Debugging" header, enable "Android debugging". Read the following carefully before you continue: Shut down your tablet and connect your USB cable. Hold the power and volume down buttons at the same time. Keep holding until you see a menu. The menu will consist of a few items, among them there is "RCK", a USB icon, an Android icon, and a "Wipe Data" icon. Tap volume down until the USB icon is selected, then press volume up. Cross your fingers and hope drivers install automatically.
They probably won't, so have windows look in the \android-sdk\extras\ folder. It should say the drivers installed successfully. Either way, open the start menu, and right click on "Computer". Click "Manage", then in the left hand pane of the new window, click "Device Manager". The "Other Devices" section may be already expanded in the center pane. If it is, look to see if "Fastboot" appears in that section with a yellow exclamation mark.
If it isn't there, you shouldn't be worried-- check for a section called "Android Phone" or "Portable Devices". Look for a device called "Android ADB Interface" or "Fastboot". It shouldn't have a yellow exclamation mark next to it.
In the event you have the device appearing with a yellow exclamation mark next to it, go HERE and download PdaNet. This was my remedy for this error. Unplug your TF300T from your computer and install PdaNet following instructions. During the install a warning will appear to install unsigned drivers. Install the driver anyway, and let the installation finish. You can now plug your TF300T back in, and it should be recognized automatically. Just in case, hold the volume down and power buttons again until your tablet restarts and you see your hidden menu again. Once again, tap volume down until the USB icon is selected, then press volume up again to select it. Check the Device Manager again and you should find the "Android Phone" section at the top. Within it, you'll find a device called "Android ADB Interface".
Now that we have your tablet and computer set up nicely, we can finally install ClockworkMod (CWM) Recovery. Go to THIS thread and download the attachment called "recovery-jb.img" (thanks XpLoDWilD!). It is VERY important that you download "recovery-jb.img" as this is the version for users with Jelly Bean bootloader!
Rename the file you just downloaded to "recovery.img" and place it in \android-sdk\platform-tools . In Windows 7, open the Start Menu and search for "cmd". You should see a result called "cmd.exe". Right click that result and click "Run as Administrator". Now type the following commands into the new command prompt window in order to flash CWM Recovery:
Code:
cd C:\tools\android-sdk\platform-tools\
fastboot -i 0x0B05 flash recovery recovery.img
DON'T unplug your tablet!! Don't close the window either! Wait for the command prompt to finish what it's doing, then you can type the final command:
Code:
fastboot -i 0x0B05 reboot
Your tablet will reboot. Once it has fully rebooted, shut it down and hold volume down and power again to access our tablet's hidden menu. This time, instead of selecting the USB icon, select "RCK" and press volume up. If I'm not mistaken, "RCK" stands for "ReCovery Kernel". ClockworkMod Recovery should load up. If it doesn't, then you were not successful in flashing CWM. If it does, then you can go to the Backup and Restore menu and create a backup.
I was overconfident when I went through all this, and I didn't make a backup-- for me, I wasn't able to get my SD card detected (64GB fat32), but even in this case you should be able to make a backup to your "Internal SD card". Unfortunately, you are on your own for this step. Make sure that you transfer this backup to your PC after creating it. You may need to disable Developer options in your TF300T's settings before you can transfer files over again.
In THIS post, XpLoDWilD gives instructions on how to Root your tablet. If I'm not mistaken, this applies to users who are using a ROM that does not already have root. If you care about Root right now, you can go ahead and flash his attached .zip file using CWM to your TF300T.
When I did this, I selected the .zip file with CWM and then went back to the main menu to select reboot. CWM then prompted me that it needed to fix permissions in order to keep Root. I tried it both ways-- first I let it fix permissions, then used a Play store app to check for root. Test came up negative, so I tried again without allowing it to fix permissions. Negative again. I tried again, allowing it to fix permissions again and then left it alone. If you are successful in rooting your TF300T, you can use Titanium Backup to backup your device later. However I used an app that did not require root that worked fine. The choice is yours.
Flashing a custom ROM
Click to expand...
Click to collapse
Now it's time to find a custom ROM to flash. For my guide I will cover Baked TF300T Blackbean #6-- Based on CyanogenMod10, and quite a nice upgrade from the stock ROM. The only downside I found is the Asus App Backup application is not included and cannot be installed. I'm unsure why this is the case-- I have even attempted to install it via CWM with no success. If you need this app or the App Locker app, I suggest you choose a non-CM10 ROM. You are on your own in deciding an alternative, but I have heard great things about CleanROM and I seem to recall reading that these incompatible Asus apps work on it. Don't take my word for it-- do your own research to make sure!
It should also be noted that ROMs like Blackbean #6 have some potentially dangerous settings that can make a power user salivate profusely.

With great power comes great responsibility

Okay, so it was his uncle, whatever. But either way, if you're going to install this ROM (or any other with overclock tweaks), BE CAREFUL when selecting different settings for CPU speed and overclocking. I used to overclock my PC as a hobby and pushed a 1.8GHz CPU to 2.77GHz on air cooling.. The thing I learned in the process is if you don't have the proper settings, your computer becomes unstable and weird things start happening. Data corruption, clicking the Start Menu does something crazy and unusual, PC crashes randomly, etc... Some of these errors are due to insufficient cooling-- a problem you cannot remedy when working with a portable device.
Assuming you are new to this tablet like I am, use this rule of thumb when dealing with foreign and potentially dangerous things: DON'T TOUCH IT until you understand it. Then when you understand it, understand it again. Then when you feel you've understood it twice, take baby steps. It's like jumping up a cement set of stairs-- you're definitely not going to try to jump five steps in your first attempt, unless you want to risk smashing your face and bloodying yourself up. Take it one step at a time-- make sure you can land on your feet before deciding to go further.
There's a lot of other options Blackbean #6 has that the average user can still appreciate, so ignore those overclocking/CPU stuff and focus on the other tweaks. Nova Launcher is included and is pretty sweet. I upgraded to Nova Launcher Prime and feel it's worth the extra $4, but I'll leave that for you to decide. There are more options than merely Nova Launcher alone, and not all of them have a price tag.
Without further adieu, let's download the Blackbean #6 ROM and Gapps. Head over to THIS official release thread for the downloads. The names of the files you want are:
baked_tf300t_blackbean-6_jb-bl_b6.zip
gappsinverted-jb-20121029-signed.zip​
Put them into a folder called "bb6" and copy the folder over to your TF300T. If your SD card is working in CWM (from CWM, go to the "mount" menu and try to mount SD card), copy the folder to your SD card.
NOW is the time to do any final backups before your fresh ROM install! I recommend "App Backup & Restore" on the Play store. If your tablet is rooted, you can also use Titanium Backup. Both will work fine, though generally speaking people seem to prefer Titanium Backup. People also seem to prefer TWRP over CWM, but I personally find the design unappealing. More importantly, I could only find a proper guide on installing CWM on a factory flashed JB TF300T.
Once you've made your backups, don't do anything until these backups are safely transferred to your PC! Don't forget to backup your music, movies and photos...
Now that you're 100% confident you've made all the backups you need and your battery is well charged and ready to go, let's flash your custom ROM! Shutdown and enter our hidden menu you should be very familiar with by now. Boot into CWM (with RCK icon from hidden menu selected, press volume up), then press volume up/down to navigate.
READ THE FOLLOWING SECTION BEFORE DOING ANYTHING ELSE:
Select "install zip from sdcard" and tap power. If you placed your "bb6" folder on your SD card, tap the power button once more. If it says "Can't mount /sdcard/" in the bottom left corner, then select "choose zip from internal sdcard" and tap power. Earlier you should have put your ROM and Gapps in a folder called "bb6". If you can't find this folder in either the SD card or internal SD card locations, GO BACK, reboot, and make sure you put the folder on your TF300T or your SD card. You should also make sure that the ROM and the Gapps file are inside that folder as well. Do NOT unzip them! They are just fine as they are. We are NOT flashing the ROM and Gapps yet, we are merely making sure they are there before you wipe your tablet. If the files are there, go back to CWM's main menu.
Select "wipe data/factory reset" and tap the power button. Confirm that you want to wipe, wait for it to finish.
Now select "wipe cache partition" and press the power button. Confirm that you want to wipe, wait for it to finish.
Go back to the main menu and select "advanced" and tap power, then select "wipe dalvik cache" and tap power. Confirm that you want to wipe, wait for it to finish.
Don't worry! Your ROM and Gapps should still be in your bb6 folder. Navigate to "install zip from sdcard" again, and let's make the magic happen. We are going to install the ROM first, then install Gapps. Only after both the ROM and Gapps are installed will we reboot our tablet.
So select the ROM first, confirm that you want to install, wait for it to finish. This one will take a long time compared to the Gapps. Just be patient and wait, even though it looks like it's not doing anything.
Then select the Gapps, confirm that you want to install, wait for it to finish.
Finally, reboot your tablet and cross your fingers. You should be greeted with the sweet victory of the startup animation. Go through the first time setup routine, and make sure the tablet works. From here you can optionally backup your custom ROM, but I recommend getting your settings the way you like them before you backup.
Give yourself a pat on the back--you survived! Hope this guide helped someone out-- I was able to sort through my problems fine, but I felt it important to share my experience. I know I couldn't have been the first to hop through these hoops anyway.
Congrats on your custom ROM Transformer Pad. Enjoy your tablet.
P.S. Questions? Comments? Suggestions? If you have any of the three, feel free to share! If it's a suggestion, please PM me and I'll see about making edits to my guide. All are appreciated, and especially anything that clears up any uncertainties I've expressed.
Special thanks (individuals and groups I owe credit for my process):
Drgravy, Team Baked, and everyone who wrote code that was used in the Blackbean ROMs. Blackbean #6 is my first custom ROM, and so far it's been great!! Keep up the awesome work!
XpLoDWilD, for CWM Recovery + Root on TF300T. These files and instructions were the major keys in making my endeavor a success
I also want to send out a big thank you to every other individual and team who has released a custom ROM for the TF300T-- admirable work, and far more than I could ever do. Thanks for giving us options and making us excited to have a customized tablet!
(....And many more! Currently in finals week (yikes) and can't recall everything right now-- will add more as I remember)

It's a shame that such a well written guide has so little thanks. Have mine.
Sent from my ASUS Transformer Pad TF300T using xda app-developers app

Very nice. hopefully this helps people just getting the tf300.
note, if you want to install TWRP recovery instead, your command will change accordingly, just make sure you type in the exact file name you want to flash. so if your recovery file is named twrp.blob:
fastboot -i 0x0B05 flash recovery twrp.blob

Thanks!
Your guide helped me a lot. I had problems only with root. Flashed 4 times, but always got "no root acces". Finally, I downloaded root package from here http://forum.xda-developers.com/showthread.php?t=1845377 and it works well

Is your tf300 new? first hand? or have u ever sent it to asus for repair before?

Well written, well thought out instructions. Many, many thanks!! I'm still having some trouble though. I get stuck once I download the unlock app, open it, agree to the EULA, then another warning appears that is a black screen white text and a yellow triangle. Nothing happens after that. There are no buttons to agree, no checkboxes, nothing happens. Any advice?
*UPDATE* Figured it out. Be sure to sent the font in settings->display->font size to small, then you will see it. The large font pushes the agree button off the bottom of the screen.

It would be great if CWM in this OP were replaced with TWRP. Many are having issues with CWM. Me being one of them. I flashed TWRP with fastboot and no more problems!
I agree with the post above. Sad that such a well written post has so little thanks. :good:

thnx for this amazing guide, but I am still unsure of this guide will work for me.
I am from Holland (Europe)
specs from my ASUS Transformer TF300T:
Android 4.1.1
Kernel 3.1.10 ([email protected])
Buildnr JR003C.WW_epad-10.4.2.18-20121122
Pad EC Version PAD-EC20T-0216
My question is...will this guide also work for me? ...since I have JB 4.1.1 & build 10.4.2.18
I am also worried about the fact that this guide in for an american(?) transformer I gues...so do I need other files then the files mentioned?
I would love to have ROOT and install a custom rom and remove bloatware etc.
thnx for the help in advance!

Thank you so much, perfect for so many people here.
Can you edit it with TWRP? I would use this right now but as above poster said there have been issues with CWM so don't want to try it.
P.s. i got mine from groupon too

Yes, it will work, I've tried it. But i suggest you use TWRP custom recovery though. CWM has high chances of getting bricked.

Could you also please add a NOOB tutorial for installing TWRP Recovery (this forum is very confusing in getting the right tutorials / avoiding outdated tutorials which would brick my TF300T etc)?
Example:
quote from XDA forum in TWRP topic: "The fastest and easiest way to install TWRP is to use the GooManager app" <--- GooMnager needs ROOT so I can't use this method?
My ASUS TF300T is completely untouched & unrooted still and don't won't to mess it up.

www.mediafire.com/?7v1gwbbzqzvzto7 <- fastboot and twrp, the twrp is out dated so if you want you can download new one from twrp website.
2)Extract the recovery with fastboot files zip and open a command prompt in the same folder of the adb and fastboot files (you must click the fastboot and adb when extracred and i suggest you put your extracted fastboot and recovery zip in C:\(foldername) and then open cmd)
3) Reboot into the bootloader of your tablet, type: adb reboot bootloader
4) When your tablet has reached the bootloader navigate with volume down to the usb icon and press volume up to confirm.
5) To flash the recovery type:
fastboot -i 0x0b05 flash recovery tf300t-jb.blob

Here is a little update on my progress...
- I unlocked the bootloader of my TF300T
- I managed to install latest TWRP
- Made a (COMPLETE) backup of the untouchedl system with TWRP <--- DO THIS BEFORE ANYTHING ELSE!
- Rooted the TF300T with the WW file in this topic: http://forum.xda-developers.com/showthread.php?t=2033205 <----works awesome!
- Made a second (COMPLETE) backup of the now ROOTED system with TWRP
- Tried installing the latest "Cleanrom 3.01 Inheritance", but got the infamous "bootloop" too...the rom has been pulled down from the forum till that is fixed ( I thought I had done something wtong flashing a custom rom, but actually a lot of others had the same problem)
- Waiting for a "bootloop fixed" Cleanrom Inheritance 3.02....and gonna try flashing it again.

first of all thanks a lot ive been going crazy looking for this!! my question is will it work for me?

i never backup.... I only backup app using titanium backuo, if something on the rom goes wrong i just reflash latest firmware from asus website. If you like custom roms, i suggest you use Energy Rom if you want OC or Hydro rom if you want just modified stock rom with better performance.

I have a problem while I try to run the flash recovery command. I have done all steps prior to this.The only difference I see is in device manager I get "ASUS Android Devices". Now, the error I am getting comes after trying to run the command, I get "error: cannot load 'recovery.img' No error" . I have also tried the pdanet solution. Thank you for your help in advance.

Stupid question... but I am going to ask it. Having never rooted my TF300 it is on latest firmware will this guide still apply to be even though I bought my device running ICS but have updated to latest firmware? Have never rooted tablets before so all new to this.

Hi @MidoTayel i have also bought a Lenovo a3500-HV less than a week ago i know of two goo tools that can help you root they are:-
Farmaroot- http://forum.xda-developers.com/apps/framaroot/root-framaroot-one-click-apk-to-root-t2130276
ROOT Genius- http://www.shuame.com/en/root/
But i would recommend that you WAIT A FEW DAYS as you know that after rooting the system can get corrupted (Based upon the app you install) thus you would send it to the service center and they would charge a lot of money(root void your warrenty). Apparently i am researching how to create and flash scattle files (Backup images of all system files,recovery.img,boot.img........) in Lenovo a3500-HV(Companies use this method to install android after the tablet is made).
Also i am researching how to create a clockworkmod recovery which will help in flashing updates and flash.zip modification and will also create nandroid backup of your entire system
If you can wait a few more days (5-6) days i will email you a set of tutorials from backuping imei numbers to creating scatter files(Right now i am sorting the best tutorial and good information from the junk in the different forums and blogs). With this information you do not need to go to the service center for any software issue anymore all you would need is an computer and a OTG cable (the cable used to connect phone to computer) and if you install custom recovery you would not need that also (Saved over Rs6000 in my previous tablet software problems)
I am also planning to make a thread upon the LENOVO a3500-HV
Also i have a few QUESTION i want to know if you are facing these problems as i want to know if it is only in my tablet or the entire firmware
-Does the tablet restart between every 4-5-6 hours
-The GPS does not work Test using GPS TEST app ( https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en ) Already found some fixes but it needs root
-Can you boot into recovery mode or does it get stuck in the boot logo
-Can you install CPU-Z ( https://play.google.com/store/apps/details?id=com.cpuid.cpu_z&hl=en ) and check if the hardware is the mt6582 model (Picture given below)
LAST of all can you give me your email id as yau are the only other Lenovo A3500-HV (Model is new) member i could find and i will first email all the tutorials i.e. doc,vedios,pdf to you and help you through email and chat
And if you only want to root and don't care it goes to the service center please atleast tell me if the root is working or not THANL YOU

GREAT !!
I finally found other guys having Lenovo A3500-HV
@MidoTayel
I guess you can use vRoot to root this model of lenovo (A3500).
But as @anandisrocking007 mentioned, I also recommend that you wait. Because the root may be dangerous without CWM recovery to make backup image of your system.
@anandisrocking007
I am happpy with your researching and waiting you…
I have some answers of your questions:
1- My tablet doesn't restart automatically ever from I bought it.
2- You can boot into recovery mode by holding the three buttons together (Vol. up + Vol. down + Power) after shutting down the device.
Other problems I will check them later.
Thanks.

THANK YOU THANK YOU THANK YOU i had thought that i had bought a tablet with a corrupted recovery as the previous model a3000 had a different set of command to go to recovery take a look at it yourself
http://forum.xda-developers.com/lenovo-a3000/general/lenovo-a3000-startup-modes-t2656140
So are you rooted by vroot
ok and one more thing power+vol up =Factory mode(Dangerous if you do not know what you are doing)
and if you can not understand the chinese this is the translation

and again thank you also tonight/tomorrow morning i will send a set of ussd(you just have to press call after typing the code) code to check if the bootloader of the phone is locked like asus(Then i can not flash and root as it will brick th phone[though the chances of this happening in lenovo is 2% as all the previous model's bootloader is unlocked but better safe than sorry])

Bootloader unlock allowed - Yes << this means that your Bootloader is Locked
Bootloader Unlocked - Yes << this means that your bootloader is unlocked
Please give me a feedback... i can make the tutorials and instructions but i also need you the give feedback and help it can incrase my work speed i shall try to publish everything by this wednesday-thusday......

Hi @ibraheem_alex so the USSD anomaly is not only for my phone its ok not to worry i am 95% sure that lenovo does not have locked bootloader also did you check the GPS is it working also use CPU-Z to check the chipset model mine is MT6582 when everything is over i would be uploading the scatterfile backup for everyone to use i just want to know if more than one type of model is released as different countries have different chipset but the same model (Pss..It won't have an impact on the tutorials that i shall post as you shall make a backup of your own phone :highfive
Tutorial Update- i have managed to download some vedios from sites and found a lot of tutorials that i have saved in .docx format just 1-2 more sites are left i shall then sort out the best one and if require will merge some to make a better one all and all i shall post it within a few days the tablet is an huge investment i think its fine to be a little patient....... (Pss...i shall be uploading it in google drive and will publish the link...:good

Hi @MidoTayel let me put this in simple words take windows for example where there is a guest account and there is a admin account in guest you can use the software but can not write anything in the C Drive(Also can't install software which are stored in C Drive) in that way Windows's C Drive=System Partition on android so when you get a phone its always in guest mode when you root it it gives you admin access. Some apps require to write or change file for it to work eg ROMtoolbox , Xposed module etc when you are not rooted the apps save all files into the data partition and if any problem occurs you can do a factory reset (i.e deleting the data partition) and it will be the same but if you are rooted and have some problem in the system partition even factory reset won't it goes to the service centre and they charge. Scatter file backup and nandroid backup are ways to backup an entire android OS ie system,data partition along with others its like you are creating an entire android installation setup and when your phone is bricked you can reinstall it. Overall i can tell you that the privilages of root outweigh the risk a lot what every you do try to research a little (I took 2 months to root my last tablet) and always make a scatter file and/or nandroid backup as soon as you root (First backup then check the cool device i.e ASAP) you root to be 100% safe
I am making tutorial to hep you root or create a backup....
Hope this helps i was confused for weeks thinking what is root when i started android..hope you don't face the same problem
PRESS THANKS IF IT HELPS.....:victory:

My chipset model is MT6582 .. It is same as your chipset.
I couldn't determine if my GPS working or not...
I used the GPS Test as you mention but also I can't know if it working correctly or not .. May I will make another test while moving in car.
But I captured this photo from the app .. May it help you.
See the photo in attachments.

Hi, I have a model A3500-FL (without back camera).
GPS works, locks in about a minute out in the open. Tablet lacks AGPS (no data connection). It's MT6582 which can use Mediatek's proprietary EPO to speed up positioning, but due to no root I cannot verfy if it is working or not.
Anyone tried backing up A3500 via SPFlash or MTKdroid tools or rooting?

Hey i wanna install the kali linux on my tab so if there is other way to do it without root it pls tell me

Hi
Me to .. I need to run Linux Ubuntu on my tablet.
But I think NO way to run linux without rooting your tablet.

This is how I rooted my A3500-FL under Xubuntu 14.04 (i have win 7 in VM):
1. install Virtualbox, not the OSE edition - get the full version from Oracle website and also the extesion pack (it enables direct access to USB devices)
2. Install windows (XP or 7, don't know about later versions)
3. Grab a copy of RootGenius from here
4. Enable usb debugging on tablet Connect your tablet via usb, make sure it is recognized by ubuntu, there is no need to mount it
lsusb for my device:
Code:
Bus 002 Device 004: ID 17ef:7738 Lenovo
5. Start your windows installation and mount the USB in virtualbox (there is a button for that at the bottom of a windows running your VM), make sure windows sees your device, it will probably fail to install the drivers
6. Start RootGenius, it should download and install drivers for this phone. Tutorial including usb debugging here. Click root a wait for a minute. Done
If yu are running windows skip steps 1-2.
Optional: make full system backup here
I did a backup before rooting. MTK tools somehow sneaked su binary past the android defences and got shell root after backing up.

Now time to install SuperSU on your phone
Go to play store and search for SuperSU and download it. Open it. After opening it will ask to update binary script Select continue and now it will ask for installation of the file. One you will have as normal mode other one would be TWRP/CWM. We don't have CMW/TWRP installed for now so select Normal mode and application will update itself!
In case if you have rooted and installed any recovery manually install the updater script from recovery. Place it in SD card reboot into recovery and install it. Download here
Installing the Recovery (CWM for those who haven't installed recovery) (With Unlocked Bootloaders)
1) Download Flashtool to your PC -- http://www.flashtool.net/download.php
2) Install it and open it.
3) Go to where you have downloaded flash tool zip file and locate "driver" there. Open it and install the C5302/03/06 driver for your phone. After installation of drivers open Flashtool.
4) Connect your Xperia SP to your PC now. Make sure that the connection is up to the mark.
5) Hit the smart lightening button on the right upper left side and select “Fastboot Mode.”. Make sure that usb debugging is on when you connect to PC
6)On the right side, click on “Reboot Device into Fastboot Mode.”
(If this doesn’t work for you, manually put your device into Fastboot Mode and connect it to your PC. To do so, turn off your Xperia device and now connect to your PC while keeping the Volume Up key pressed. As soon your PC detects your device,the blue LED will turn on showing fastboot mode.)
7) Now click on “Select Kernel to flash”.
8)In the format selection, by default it will be “*.sin”. Change it to *.elf.
Now select the DoomLord Advanced Stock Kernel.elf file that you downloaded first of all and flash it.
9)This kernel will flash CWM recovery in your device. Disconnect your device now.
Turn it on, as soon as you see the Sony Logo, press Volume – Key 5 to 6 times and you should see the CWM recovery interface now.

1. There's no need to change kernel to root
2. U can't install custom kernel with locked bootloader,u're ure giving instructions to brick phones
3. There's no need for towelroot to have internet acces to work
4. And talking about Towelroot, there's a thread with towelroot in this forum (about three actually)
5. There are recoveries for locked booleaders, also there's an index with it in general
5. What with all ad f.ly and ad links? are u trying to make money? put a link to the original thread or the links of creators if is not your work
6. Red is a really bad color to be the main in the thread
just sayin'

Apologies on first part for letting adfly links on the tutorial wasn't aware of this rule.
Secondly towelroot gave error on my Xperia SP that "Please make sure you are connected to internet" that's why I advised to stay connected likewise SuperSU would take Internet connetion to download then why not to be on safe side
As considered with that custom kernel flashing thing thank you for correcting me! You saved a blunder mishap and prevented it from happening thanks a LOT!:highfive::angel:
I always give credits to the one who created the original stuff! I NEVER TAKE CREDITS FOR OTHER'S WORK
And RED is a color that is easily hilighted and people actually pay more attention to words written in red rather than any other color
Just Saying

:good:
Wut? Towelroot now needs internet conection? D: maybe sounds paranoic, but don't like xD
and one more thing, you can install SU from the zip w/o recovery, just open the zip with a file manager and look into 'common' folder, there's a Superuser.apk in there, install as normal APK, and you can update binaries with the zip w/o internet too (just open SU app and click normal, the same as you said)

[GUIDE] [KatKiss 6.0.1 & PlayStore] [STABLE-NO BOOTLOOP]

Timduru's KatKiss MM 6.0.1 ROM running stable with no bootlooping GUIDE
As many of you know that have tried to bring your TF101 back to life with timduru's KatKiss 6.0.1 ROM. I've been working with this tablet for about the past week and finally got this thing running stable with the play store and has not bootlooped once.
First all credit to timduru for this rom. All I did was figure out a way to get play store on it without all the rebooting. Now that I've got this thing running stable it's definitely a clean ROM and very fast and efficient. The actuall KatKiss thread has a bajillion posts and way too much reading, and since it's the most updated ROM that people are likely to be using or wanting to use I made this thread/guide so you all can enjoy it also without the bootlooping.
YOU'LL NEED A LINUX VIRTUAL MACHINE OR COMPUTER. I used Ubuntu 18.04.
1.)First of all, if you don't already have the ROM and SuperSU you can download it from timduru's thread
KatKiss 6.0.1 by timduru​SuperSU BETA 2.52 from timduru's thread​2.)Do a fresh install of the ROM from TWRP
3.)Install the F-Droid app
4.)In F-Droid Settings, Enable "Expert Mode" and "Unstable Updates"
5.)Add a repository for MicroG "https://microg.org/fdroid/repo" leave fingerprint blank
6.)From F-Droid search and install
a.)microG Services Core​b.)microG Service Framework Proxy​c.)Apple UnifiedNlp Backend​d.)NominatimNlpBackend​Now is when you have to break open your linux machine...
7.) Make sure you have ADB and fastboot setup properly
PHP:
sudo apt-get install android-tools-adb android-tools-fastboot
8.) Then we're going to use ale5000's "tingle" from GitHub to achieve signature spoofing. The method posted using Haystack no longer works.
PHP:
git clone https://github.com/ale5000-git/tingle
sudo add-apt-repository universe
sudo apt-get update
sudo apt-get install python3 p7zip-full default-jre android-tools-adb
sudo apt install python
9.) Once it's all setup connect your tablet to your Linux machine via USB. MTP mode and enable USB debugging.
10.)
PHP:
cd tingle
python main.py
Select "1" and press enter
11.)Let the commands do their thing, it may take 2-3 minutes, it'll finish automatically. Once done reboot tablet
12.)Open MicroG Settings in your app drawer
a.)Tap “Permission Missing” and give all permissions​b.)Enable “Google device registration”​c.)Enable “Google Cloud Messaging”​d.)Go in “UnifiedNlp Settings”, tap both “location backend” and “address lookup backends” and enable the backends there.​e.)Go back to the main menu of microG Settings and goto “Self-Check”, check “Battery optimizations ignored”​You'll know everything's set up right if you see "System Spoofs Signature is checkmarked on its own
13.)Download the latest Play Store APK and rename it to "com.android.vending.apk"
14.) Then in terminal, be in the same directory as the location of the play store apk you downloaded and run these commands
PHP:
adb remount
adb shell mkdir /system/priv-app/Phonesky
adb push com.android.vending.apk /system/priv-app/Phonesky/
15.) Reboot and log in to Play Store with no issues.
All credits to timduru for the rom and leading me down the path of searching for working signature spoof options. and credit to ale5000 for his tingle program. I hope this helps all of you. If you have any questions feel free to ask.

Thank you for the great guide.
Does Google Play Store works well after all those steps? (Self-Check in microG shows all marks checked)
I've authorized properly but it shows "Error retrieving information from server. DF-DFERH-01" after.

Great guide. Quick question. When you say download googleplay apk, which version? Where from? Is this the genuine google play store or G-apps? Going to try this at home tonight.

great guide
has anyone had any luck with this? personally I can't open any apps downloaded from playstore
Also get a message after boot:" Nominatim Geocoder Backend isn't responding"

ANy hint on how to update Android Webview
Chrome and other apps do not work

Thnx! Works great
Chrome v 49 works well for me.. the later ones crashes.
Got use for the old device again..

Just installed this...(without playstore)
Now what apps do you guys recommend for smooth video and web browsing and file managers?
And where do you download from ?

hello, just went through the whole process and my tf101 works but: cant get play store to work, every time i sign in i get a message that tells me i have already signed in and the play store will not open up. by play store I mean com.android.vending.apk , and I used my laptop running Mint to push every script in the order and directory as described in this post. before closing I would like to thank aarron and Timduru and others like them for the hard work that has let me make my phones and this tf101 something really special and blast to use. btw, the tf101 does work, and no bootloops!

Hey, I just went through your tutorial and everything seems to be working perfectly. Great job and thank you!!!

Dusted off my old tf101 and tried this set up and I was not able to get playstore working, went back to the old setup with v 6.0 and g-apps and back to boot loop, I will attempt the whole set up again. Thank you for your works guys.

I also tried this guide, I'm able to install apps from the Google Play store, but almost every app that I try to open made the TF101 crash and reboot. For some apps by google, it goes into bootloop. Similar issues also for apps installed via F-Droid. @aaron2z I'm wondering if this guide is still valid and if there is a specific version of Google play and other apps such youtube and hangout that are supposed to be used in order to avoid bootloop.
Thanks

Hi !
I tried this great guide. Thank you !
Despiste this guide, I have problems with apps from Google Play Store : self-boot, bootloops.
I'm trying to install APK apps directly without Google Play Store. TF101 seems to be stable, for the moment...

Hi!
I also got the bootloop and google play errors, so I decided to go without google services. Formatted, installed ROM and SU, wiped dalvik and cache. Everything goes smoothly, but when I try to install the K.A.T. app, I get a "Can't open file" message. Same thing with any other apk. Of course I don't have a file manager installed, and it's the first thing I wanted. I tried to install it by browsing to my apk using the "hidden" file explorer (in Settings under Storage and USB), then I also tried to download the apks using the browser and opening from there, but I always get that same message. Of course I have the Unknown sources enabled under Security (it is enabled by default on this ROM apparently).
And now I don't have access to my Ubuntu box (F*** Coronavirus).
I don't mind having to download the apps and install them manually (as opposed to through Google), but if I cannot install anything, then there's not much I can do with the tablet :-/
Anyone has a clue what's going on? I'm sure I'm overlooking a small detail, but I'm just wondering what it is... Apparently I cannot open apk files with the buit-in file manager, but there's nothing else I can use to open files. And I can't install another file manager since I cannot install apk's...
@SnakyTheToops, you wrote

How do you manage to install apk's?
Any tip is welcome!
Cheers!

Hello,
I installed "simple file manager" with fdroid

Thanks. I tried to download fdroid, but same thing, couldn't install the apk. For anyone interested, I just used ADB to sideload the apks I wanted. Once I've installed a file manager, I can install apks from wherever.

Hey,
Does somebody has an idea to update webview ? Some webpages don't render well or don't even work ..
Thanks

I dusted off my tf101 last week and attempted to go through the steps to get TWRP and get the newest possible rom which seems to be katkiss 6.
Well I tried using adb commands through powershell on my pc and also tried installing the TWRP app so it would help install the custom recovery but i can't seem to get this to work. The threads I tried to follow on here for installing a recovery are all over the place and seem to gloss over step by step instructions so I am stuck. This is only my second device that I have ever attempted to install a custom rom onto. The first one was my 2012 nexus 7 which went smooth and easy without any problems so I was thinking the tf101 would be easy enough as well since I already cut my teeth on the nexus, lol. All I know right now that I can tell you is my tf101 is running android 4.0.3 from 2012 and I haven't ever tried anything with it until now except I did do a factory wipe/reset last week during the process of trying to figure things out. The TWRP app doesn't seem to work with the tf101 and it does say "device not rooted" at one point when backing out of a menu option. I read that the tf101 isn't required to be rooted and does not have a locked bootloader though. Is this correct? Should I be trying a different custom recovery?

Hey,
To install the custom recovery, you have to put your tablet into the APX mode.
For that, you have to connect your tablet in USB to your PC then, switch on the tablet while pressing on VOLUME +
The screen will remain black it's normal. Your PC will detect the tablet, You're now in APX mode.
Now you just have to use this tool https://forum.xda-developers.com/showthread.php?t=1688012 and it will flash an old version of TWRP, just use that recovery to flash the latest version of TWRP and you're done !

Okay I installed the Easyflasher 0.8.3 a little while ago and then I believe I was able to get the tf101 into APX mode by holding the power and volume up buttons at the same time for about 5 seconds. My PC made the little connection noise for stuff plugged into a usb port so I assume that meant that APX mode was active. The screen was still off on the tf101. Then I opened Easyflasher and let it flash TWRP 2.2.1 and it said "finished, now boot into recovery!"
This didn't work. I restarted the tf101 and held down power and volume down until the prompt for pressing volume up to start up the custom recovery kernel. The android bot picture shows up and there is a loading bar underneath but then after a few seconds he is on his back with the red "!" triangle and the progress bar is gone. Tried this with both versions of the easyflasher modes for tf101 S/N that are below and above B70. Neither one worked. hmm
