Ditto! Needing help as well.
1. This is N7 General section. Ask questions in Q&A section.
2. Go to Nexus 7 Development section. Download 4.3 flashable zip. Flash in recovery.
3. ????
4. Profit
You probably don't have a stock recovery though... This breaks OTA's.

I have it completely stock.
Is there anyway to install 4.3 without losing any data?
I was getting the ERROR, and i did this, works well, but i had to delete everything from my tablet, so better make a backup!
1. Download the toolkit here: http://forum.xda-developers.com/showthread.php?t=1809195
2. Install the toolkit to the default C:\ folder it tells you to
3. When launching the toolkit it will ask you which version of android you're running (I was number 15)
4. Install the device drivers (option 1)
5. Download 4.3 from here: https://developers.google.com/android/nexus/images (specifically I downloaded ' Factory Images "nakasi" for Nexus 7 (Wi-Fi), version 4.3 (JWR66V))
6. Put the factory image in: C:\Google_Nexus_7_ToolKit\put_google_factory_image_here\
7. Turn off your Nexus 7, turn it back on holding the power button and both volume + and volume -
8. Plug in the USB cable
9. Select "option 3 - unlock / relock bootloader" and follow the steps, it will the come up on the Nexus 7 telling you you're about to unlock it; us the volume buttons and power button to select ok
10. Select "option 9 - Download, Extract and Flash google factory stock rom"
11. Select "option 2 - flash google factory image" on the next screen
12. Follow the instructions typing yes where it needs (Note. the checksum did not match for me!), keep following the instructions..
13. Device will reboot after it transfers across and boot into 4.3 - complete the setup process
14. After the setup process is finished, plug it back in and select 'option 3' and relock the bootloader!!

Hi all!
I'm an andoird newbie and I've a big problem with my tab!
I was using the NX Manager by my PC to unlockink my android table and installing CWM.
All was going all right but, while I'm using CWM I was entring in the Format/Mount section to mount "system" but I've click the wrong botton in the wrong line and I've format my system dir.
Now I've my nexus block on the main page, where ther is the "Google" string on black screen.
I thinks there's no problem because I'll can install an new Rom (like cm 10) but, when I connect my device to my PC, the PC don't recognise my tablet! And I can't reboot the tablet or entre in recovery mod! Is block!
What can I do!?
The Rootkit don't go, the NX manager don't go (because I was hoping thet they reboot my tablet in fastboot).

So what's the issue, you don't have a recovery installed any longer?

No because I've done a mess!
I' ve formatted the "system" folder, and now my tablet is freezed on the startup screen, with the Google logo, and if I try to reboot it/shut it down, the tablet doesn't work. So i'm locked in this situation.
I've downloaded two roms: CM 10 and the orignial google roms.
The very big problem is that:
Windows doesn't recognises my tablet! It says that I've connected an USB MTP but don't open anything! So I can't do aything...Is there any flasher program that can help me?
A good way to reboot it may be to turn off the battery opening the back dock, but i'm not good in hardware-hacking so I wonder in any other solution.
Thanks
Just now I turned it off holding the Powerbutton+Volumeup ( but now doesn't reboot in any way) and Windows recognises it as an APX device
Another edit:
I just rebooted in the bootloader, but when I start the Recovery Mode, the tablet freezes on an "android" icon with a red "error" icon
Thanks
You can either do one of two things:
1. Start over from scratch going back to complete stock. This will erase your internal sd card, so anything there will be gone. Hopefully you have a backup if anything important is there.
LINK: http://forum.xda-developers.com/showthread.php?t=1907796
NOTE: Assuming you unlocked your bootloader already, start reading under the heading Flashing Factory Image, start at Step 3.
2. You can boot into the Bootloader, connect the tablet to your computer, use fastboot to flash a custom recovery, then use adb to push the CM10 zip file to your device, flash it in recovery and reboot.
There's a few steps involved in each, both use fastboot commands, so it's really up to you. I can explain either.
EDIT: The methods I'll describe do not use any sort of toolkit, which is also known as the "manual" way of doing things.
Problem solved!
Ok, I MADE IT!! :victory:
I forced the shutdown pressing PowerButton+Volume UP, then i Rebooted the device pressing PowerButton+Volume DOWN ( Fast Boot).
Then...
First of all I downloaded the Nexus7 Toolkit of XDA Developers,
- I downloaded the flash stock (Google/Nexus) ( Step 9 of the toolkit actions)
- and flashed the device from the Nexus7Toolkit (Step 9 of the toolkit actions again)
Then the device returned in "factory status", including the Bootloader version ( Removing the old Recovery Mode).
Problem Solved! :laugh:
Thank you very much for the instant support.
I was misunderstanding some things about installing the ROMS ( I've tried to Push the factory stock into the tab - Step 13 of the Toolkit) , so I thought I came in trouble, but following step by step the Toolkit commands, I made it.
Thank you so much.

You're welcome, glad I could help!
I have a rooted Nexus 10. I recently received a popup that an update was ready to install (4.4.2). Somewhere during the install process it crashed. I can't remember exactly what it said but something about e:\ and invalid files. Now when I boot the tablet it loads the Google logo and then it displays the 4 color ball animation until the battery dies. I don't mind wiping everything so I downloaded the 4.4.2 rom from google and figured I could wipe and flash a fresh copy. The problem is I can't get ODIN to see my tablet. I plug in the USB and I hear the normal chirp that windows has found new hardware and it installs some strange driver (SAMSUNG CDC?) but ODIN never loads a com port.
Any thoughts on what's wrong, or other ways to try to fix the tablet?
Thanks.
I'm afraid I don't know much about ODIN....but:
I think there's hope yet! First things first, download the (dl.google.com/android/installer_r22.3-windows.exe) Android SDK Tools and install them - you'll need at least the Tools and the USB drivers.
Once those are installed, launch a command prompt (windows key + r on the keyboard, type in cmd and preess enter). Use cd and the tab key to get to the directory where you installed the SDK tools (e.g. cd "Documents\SDK Tools\platform-tools").
Now, on your Nexus 10, go into recovery by pressing the power button, volume up, and volume down buttons at the same time until you see a little Android with a red exclamation mark (I believe). Then, to show the menu hold the power button and volume up. Choose "Apply update from ADB"
Back on the computer, on the command prompt, type "adb sideload C:\Users\Where\You\Downloaded\The\Rom" without the quotes. It should transfer the rom to the nexus 10 and reflash it.
Please, let me know if you have any questions, I'm happy to help!
Have you tried doing a factory reset/ cache wipe in the recovery? (hold vol up+down and power from tablet off , then select Recovery Mode in fastboot)
You flash the factory image in fastboot NOT Odin .. you dont flash anything in Odin for Nexus you do everything thru the bootloader/fastboot

First off tried just doing a wipe/factory reset and that didn't solve it (but thanks for the suggestion NewMagnus).
I was able to get into recovery and sideload the rom over. After it copied this is what came up on the Recovery (which by the way appears to be ClockWorkMod 6.0.1.6, which I don't actually remember installing but oh well):
Restarting adbd...
Finding update package...
Opening update package...
E:Can't open .temp/update.zip
(bad)
Installation aborted.
So, small progress but still no joy.
And an update...
I ran the Nexus Root Toolkit again but restarted the bootloader first. This time it somehow found FASTBOOT and installed the image no problem. I'm back up and running now. Wahoo!
Thanks for the help to get me here.

Well, as bad as it is to say, I'm glad I'm not the only one who had this problem. Thanks for the advice, hopefully I can pull a Lazarus on mine, its been dead and buried in a drawer for months. Unfortunately my SIII just bit the dust (permanently) so its time to try to resurrect this one again.
I captured the lollipop update that came out today. I have a nandroid backup and I'm going for the update. We will see if the new tethered CWM works to get root back... Stay tuned.
Turns out rooted users will need to return the tablet to KitKat stock. I found this info in 2-3 places in various languages. Here is hopefully a clear step-by-step to get back to KK stock and then take the OTA.
This can BRICK your device, so use at your own risk. Files are supplied as a courtesy and not mine
1) Download - This - AFH - kitkat-YT2-1050F_S0198_150422_ROW.7z (This updated readme file here)
2) Extract the zipfile to a directory on PC somewhere
3) Goto "tools" folder and install the exe's in this order
a) PhoneFlashTool_4.4.4.1_external_win32.exeb) iSocUSB-Driver-Setup-1.2.0.exec) IntelAndroidDrvSetup1.5.0.exe4) Start PhoneFlashTool and select settings (Upper left corner)
5) Tick "force sparcing" and change size to 500mb
6) Power off tablet and connect with usb
7) From off, hold volume up and power until tablet vibrates and release power (still holding volume up)
8) Tablet should now be in "Droidboot" and PhoneFlashTool should list it on the top
9) In PhoneFlashTool click browse and select flash.xml from the "target_bin" folder
10) WAIT!!! until you see "Result okay" on tablet AND "Flash Sucess" in PhoneFlashTool
11) Reboot
12) When Android starts skip all dialogs (tablet is going to factory reset anyway)
13) Select Contacts from desktop and make 1 dummy contact
14) In the search bar type "####6020#" and then select your country
15) Tablet reboots and you are on stock KitKat again and should receive an update notice for Lollipop

Are you rooted? If so you need to "unroot". That can be done as simply as going into the settings of SuperSU and selecting - full upnroot. Or you may need to flash back to original stock...
Have you done the Update without problems?

SUCCESS, LOLLIPOP IS WORKING!!!
I Have restored original KitKat ROM via "PhoneFlashTool" with this ROMs / Tutorial:
http://www.android-hilfe.de/thema/tu...ianten.697884/
This time i´ve made the "Country Setting" via ContactApp ####6020# to "DE" befor download and upgrade!
And i have aborted the automatic PlayStore updates for Chrome etc...
Lollipop upgrade reboots into recovery and stays 5min. at 100%.
Then reboots into some intel-flash mode and stays for 4min.
After it reboots into Lollipop OS...
I have the same problem, only that I had the first Lollipop version for 1050F with root and then got the new Lollipop update. The Kitkat version fails to flash. But here is what helped:

and download the LtoKKxml.7z and copy the files into the kitkat firmware folder and then flash using flash-LtoKK-PVT-810.xml
I had to remove the parts of the XML that erase and format data. Then it worked
After that I could flash KitKat!!

Well, I got as far as extracting the original kk firmware, installing Intel phone tool and drivers with no problems. My issue is the tablet is recognized by the Intel phone tool while the tablet is in Android but when I reboot to fastboot it isn't.
This is in a virtual machine because I don't do Windows on hardware, only VirtualBox.
I may have to take an old rig and install Windows temporarily...
From my LG-G3 running Jasmine8.0/Skydragon Kernel 4.2
VitualBox maybe a problem, but why it works when in Lollipop OS and not in droidboot?
Firewall? ADB in developer-options enabled?
Try check your device manager in fastboot-mode if there is some "Unknown device" and install ADB driver...

Root - no problem - Trigger 4
Update successful to YOGATablet2-1050F_S100067
Mine was a pleasant suprise.
LenovoPad YOGA Tablet 2-1050F
I already had installed Lollipop YOGATablet2-1050F_S100031 and rooted.
When advised there was a new OTA update, I did the following:
1. From within SuperSU Pro settings "Full unroot"
2. Reboot
3. Connect to PC
4. Run Lenovo Smart Assistant
5. Update was available, which downloaded to my PC
6. Lenovo Assistant began to transfer the update to the tablet, but ultimately (2 mins?) reported "Update failed"
7. Disconnected tablet from PC and turned it off
8. Simultaneously pressed volume down and power button, released volume key on vibration
9. Black screen quickly followed by the Android icon processing the update
10. Update successful to YOGATablet2-1050F_S100067
11. All data intact
12. Re-rooted using T4 (above.)
One happy camper! :laugh:
Oh, and Xposed-v67-sdk21-x86.zip successfully installed with this version!

Thanks a lot for your description. I've been postponing this for a long time. I finally did the upgrade today. 100% successful.
Hello,
I tried many guides on web for changing the firmware from 5.1.2.0A to 5.1.2.0G without any luck.
The phone goes in bootloop and the only way to restore it is to flash again the original 5.1.2.0A firmware.
Could someone please suggest me a good guide or give me a good hint?
Thanks much!

1. turn off device
2.Press VOLUME UP+POwer key, (press Power until you see logo, VOLume UP until you go in Recovery)
3. Connect phone to computer,the computer determined removable disk Recovery, empty volume of 998 MB
4. Copy the firmware in the drive and disconnect the phone
5. DON'T Reboot!! JUST select the firmware update. You can do it without wipe data. Click Start (retry, many may be different)
6. After flashing the phone is turned on again. If root was included - will again include.
hello..
is that work on meizu pro 5?
Converting the phone from A to G isn't as simple as the classical firmware upgrade. The version is checked and flash is denied if not the same (A =>A only)
Look at this tutorial and use method 2 or 3 : https://meizufans.eu/forum/topic/25...ional-firmware-on-your-chinese-mainland-meizu
It's fine for A=>G or A=>I
Didn't worked for me
I'm the owner of a meizu pro 5 runing Flyme 5.1.2.0A and none of these two methods worked for me. When I run the terminal commands both on phone or computer, it seems to do something, but when I reboot the phone always go to bootloop, and the only way to use it again is flashing the A version of the frimware again via recovery.

Assuming you applied the correct commandline, you have to wait several minute (about 10) to the dd=xxxxx process end. Prompt should appears when OK.

Yes, I know. The command line says the process has finished, then the phone is inresponsibe (As it has to, following the explanation on the meizufans web tutorial). Is only then when I reboot my phone and enter to bootloop.

After flash, you can try to reboot in recovery (volup+power), clear data and then reboot normaly. First restart is a bit longer but you knows it already.
PS: did it a week ago with lastest G, without trouble
Thank you for your help. I would try it!

U r right!
I have just used this way to save my pro5 xD
Telefonu A dan G ye değiştirdim. Fakat Bootloader unlock yapamıyorum. Update.zip yüklenmiyor. Hiç birşey olmuyor :S
Hello, going to put this here if it helps anyone else out. Couldn't find a post that helped (there may be I might have not looked hard enough lol)
So after leaving it for a week today I let my Nexus 9 WiFi only do the latest OTA security update, halfway through it came up with an error and on reboot got stuck booting with the little Android fella on his back with a message saying it was corrupted.
First thing I went to do was install the factory stock image, but this would not let me as I had not unlocked the bootloader (and couldn't as I couldn't access the Dev menu in android previously). Tried a few other things including factory wipe/fastboot/etc and this is what fixed it for me
Note: you need ADB installed (plenty of ways to do that on XDA)
- Download latest OTA here
- Connect tablet to PC with USB
- On the recovery screen bring up the menu (Power button + up)
- Select 'Apply update from ADB'
- [Windows] Bring up CMD and navigate to the update location (Hold shift + right click brings up the option to open CMD in that folder location)
- Type 'adb sideload (ota file.zip)' in brackets is the file name of the download (Copy the file name and right click into CMD/Paste)
- Tablet should update and be working after that
I also wiped Cache after installing the image, whether you need to do that I don't know. Tablet is now back up and running. I had factory reset the unit before trying this, so I don't know if it will keep data. I assume it would do as OTA don't normally wipe data.
Hopefully this helps someone
This issue pops up every month with corrupted OTA process.
