[HOWTO] Update to 4.0.3 OTA ICS from any version with Root access (For I9020T/I9020A)

Okay First of all download the following files
a)http://android.clients.google.com/packages/ota/google_crespo/VQ8PQk_V.zip (4.0.3 OTA)
b)http://android.clients.google.com/p...a25375426.signed-soju-ota-189904.1ada2537.zip (2.3.6 Official I9020T Build)
c)http://bit.ly/su2361ef (SU flashable)
d)http://forum.xda-developers.com/showthread.php?t=988686 (Grab recovery form this thread)
e)http://developer.android.com/sdk/index.html (Grab the android SDK installer)
f)http://attachments.xda-developers.com/attachment.php?attachmentid=687157&d=1313224429 (Radio file only required for I9020A)
Okay so when done with all that proceed as follows
1) Backup your current apps using Titanium Backup (Optional/Recommended)
2) Backup(Nandroid) your rom using backup option in CWM (Optional/Recommended)
3) Do a full wipe, wipe sdcard, system, data, cache Transfer a,b,c,f to your phone.
4) Flash the 2.3.6 Official I9020T Build you had downloaded using the install zip option in CWM (IMP-DO NOT REBOOT RIGHT NOW)
5) Flash the flashable SU file you had downloaded and then reboot.
6) Once your phone is on, continue to set up your account or skip it as you wish. (Optional)
7) Open up market, download the latest SU app, Voodoo OTARootKeeper, Titanium Backup and any other app you use that requires root.
8) Open the updated SU app, hit menu button and click preferences, go all the way down, click on su binary(tap to check for updates) , and make sure it updates to v3.0.3
9) After that is done, open and allow root permissions to all your root apps. (This is important)
9.5) Run Voodoo OTARootKeeper and click on protect root, make sure all options get checked.
10) Turn off phone, keep volume up and power pressed to boot into fastboot.
11) Select recovery with volume buttons and use power to launch.
12) Once you see a android bot image and an arrow image, keep volume up pressed and press power once, then you'll see some options appear.
13) Select apply update option and find the official 4.0.3 OTA file you had downloaded and flash. Reboot.
14) Once you have booted into ICS, go to Voodoo OTARootKeeper and select resture Root, all options should now be ticked, if not something went wrong.
15) Voila, you have root. Now to get back CWM recovery you can follow this -
i) Place the recovery img file in the android sdk platform-tools folder
ii) Switch to the directory where you unzipped the Android SDK & go to "tools"
iii) Then type "fastboot flash recovery yourfilename.img" & hit enter
iv) That should do it.
v) Optionally you may do it form Rom Manager too, if it works.
16) (ONLY FOR I9020A) Reboot phone, turn it off, boot into fastboot, select recovery, CWM should launch, flash the radio file you had downloaded to get radio working on I9020A (ONLY FOR I9020A)
Root only works for the apps that were installed while on 2.3.6
http://downloads.androidsu.com/superuser/Superuser-3.0.7-efghi-signed.zip , use this root file, flash it in cwm, everything works, permissions etc.
This might work for other variants, tested on I9020A and I9020T, I take no responsibility for anything that might go wrong with your device. I take no credit for any links or procedures provided in this guide, I just tested and compiled.
Thanks and best of luck.

Good guide but first two links are broken.

Thanks, fixed.

Do I really need to flash official 2.3.6 before ICS? what if I wipe and format then install 4.0 immediately?

Might not work, though you can try, if it fails, do it my way, also its impossible to get any kind of root that way.

Link for the ATT Radio doesnt seem to be working

Great work!
wipe SD card?
Is this necessary?

I don't think it's necessary to wipe the SD card, I followed the procedure in http://forum.xda-developers.com/showthread.php?t=1396913 and although it said my SD card would be wiped, everything was still there after I was done!

Anyone on a i9023 tried this?

Hmm...does "any version" includes M200(Korean Nexus S)?

I think he meant that for the 9020A radio

Link fixed, sorry for that, SD wiping might not be necessary, but I suggest as it makes it cleaner. Might work for I9023 and M200, I have no clue, maybe some experienced developer can answer that better.

Not to crap on a great tutorial, This is exactly what I would be looking for if I were not already set up and running. Last night was a dizzying whirlwind of flashing, high heart rates and finally becoming familiar with fastboot and flashing things like that.....lol
But in the end I simply found a cwm flashable zip without radio or bootloader and installed through cwm like any other rom. As far as root all I did was flash a zip file found on the forums and I was good to go.

Hi mine keeps hanging in the boot animation and can't get into recovery, what else can i do? Is my phone bricked?

little hiccup at step 12. im getting the android bot with exclamation mark but i press volume up with power and nothing happens. menu doesnt show up....
Edit: NVM... i pressed it 3 or 4 times and it finally worked

Many ways of doing it, I just am suggesting one, the flashable zip for ics isn't available as yet, what did you flash?

i9020 keeps getting status 7 aborted and my padlock is still unlocked on t-mobile 2.3.6

Has any tried this on an i9023? Thank u

[GUIDE] CWRecovery flashable working Root SperUser for stock ICS 4.0.3

1. Place the superuser.zip file attached at the end of the post on your sd card.
2. Flash recovery in bootloader with "fastboot flash recovery <filename>.img". I recommend CWM 5.0.2.3 found in this thread - http://forum.xda-developers.com/showthread.php?t=988686&highlight=recovery
3. Go to recovery, in "mounts and storage" select "mount system" and then flash su-install.zip (EDIT : Mounting system not necessary, the script does it automatically while flashing the zip, but just in case)
4. Fix Permissions and reboot system.
5. Use any root explorer (i recommend ROM Toolbox, free in market) and go to /etc and either rename "installrecovery.sh" to "installrecovery.sh.old" or just delete it (its not needed).
6. There it is - Rooted ICS with a recovery that sticks.
EDIT -- IF, by any chance, after following the above steps, you find that you're stuck without a recovery (android exclamation screen), just flash a recovery via fastboot and you'll be fine. This time the recovery WILL stick. I think its something to do with the su-install.zip. I dont know for sure because I found it off the internet, its not mine.
Also, I did the superuser market update and I DID NOT lose root. I have an I9020T. So others with the same can safely update, imo.
Thanks to ab.grafix for being a part of the team.
IMPORTANT -- The su-install.zip posted previously is NOT mine. I didnt know who made it but just found out. All credit to dzo binary and Chamb'. I just made a guide coz it worked for me and I thought it might help others too.
Tested on I9020T and I9023
Don't forget to click on that thanks button if this helped.
UPDATE -- Superuser was updated by ChainsDD to support ICS 4.0.3. Thank you ChainsDD! Updated zip is now attached.

So now that we have root we need a overclocked kernel...

works great but very old cwm

Worked as described. Thanks !

Old cwm? Wich version? Is it possible to flash the latest one with rom manager?
So I am on ICS alpha13.
I9023
- wipe everything and Flash Android 2.3.6/GRK39F/XXKF1 Radio/KA3 Bootloader via clockworkmod
- Reboot in stock recovery and flash stock ICS
- Boot in ICS enable debug mode
- Run the bat follow instruction?
Is it ok?
Thanks

Hi will it work on the rogers i9023a? Can someone tell me which stock ICS to flash?
Thanks

Thanks, it worked and nothing was wiped since I was already unlocked. With apps that require root you no longer get asked for root permission nor do they show in app list in superuser but it seems to have root for now

For the guys using linux (like me ) , just download the archive in the first post , retrieve from there 2 files: root.zip and recovery.img and use them with your current ADB setup.
HOW-TO:
Prerequisites: you have installed Android SDK, fastboot and you have set-up correctly the udev (ubuntu).
1. Place the above mentioned 2 files in the working directory
2. reboot in bootloader mode (vol-up + power)
3. connect USB cable
4. run "./fastboot-linux-i386 flash recovery recovery.img"
5. reboot bootloader
6. reboot recovery
7. mounts and storage -> usb mass storage
8. copy root.zip in the phone storage
9. go back -> install zip from sd card -> root.zip
DONE !
I just tested and is working fine.
If there are newbies out there trying to understand the nonsense I wrote, try following the rooting guide for Gingerbread and just use the 2 files I mentioned in this post instead of the ones in the archive for gingerbread.

when in BL i dont have Unlock option :|

Thanks for your effort.
But I'm curious about the flashable zip file.
What's the difference of the zip file between the orignal superuser ?
And did the recovery do some magic which CWM can't do?
After reading the script , I just see the zip is important ,maybe the recovery is doing some magic too.
I'll just flash the zip and see what happen.

In fact, you can use any recovery image you want, including the latest clockwork for example. I used TWRP to do this and it worked just fine. On linux, just flashed root.zip.

I've done it, thanks a lot. I've also replaced the recovery.img file with the last cmw and all went well.
Now the rom doesn't show the root permission request toast but it works however.
I'd ask if its possible to manually update the superuser.apk or its better to mantain this one?

Great .. I'll do that because I miss my "old" cwm
EDIT: it worked, thanks!

thanks, working here on 9023. warning for other users - do not update superuser from the app itself, or it'll stop working. at least it did for me, when i updated it to 3.0.3

confirmed working I9020a...

[Q] "K1" Factory Recovery

Is it possible to restore back to the factory ROM on the K1?
I ran through the "Rooted Lenovo TOOL -Lenovo IdeaPad K1 ONLY!-" from the Dev forum. I tried a ROM recovery with the update.zip/update.xml in the download folder. Can't seem to get into the recovery rom and once the system boots the update files are removed from the download folder.
Can someone be kind enough to point me in the right direction.
Thanks
I watch the video and yes I'm a n00b!

If all you care about is getting it to some "stock" version, and are okay with it being rooted. Try the nvflash method from khanning. There's a thread on rootzwiki.

K1 to stock 14_14
I currently have the K1 rooted with the 13_13 update.
I have the recovery app installed, and I am trying to install the 14_14 OTA I downloaded from Lenovo. However, the ROM I flashed with has the K1 as a Xoom tablet in system>About Tablet.
When I use the recovery app and navigate to install update.zip it fails because it is recognizing the wrong device and fails.
How do I flash the 14_14 to my Lenovo K1?
Thanks

Just posted it the other day.
If you want 14_14_120109 stock not rooted
http://forum.xda-developers.com/showthread.php?t=1560441
If you want 14_14_120109 rooted with CWM
http://forum.xda-developers.com/showthread.php?t=1564002
If you don't want to reflash everything because your trying to keep all your data intact then:
**This would remove root and recovery but your data will be kept**
1. Open the update.zip that you downloaded from Lenovo. K1_A301_14_14_120109_US.zip
2. Go to META-INF/com/google/android/ and open updater-script
3. Delete these lines from the top:
Code:
assert(!less_than_int(1326090640, getprop("ro.build.date.utc")));
assert(getprop("ro.product.device") == "K1" ||
getprop("ro.build.product") == "K1");
4. Save the file and flash via recovery
Before you flash the zip in recovery make sure you toggle signature verification

[Complete Guide] SHIELD Tablet K1 Root, Custom Rom and Xposed Framework

Hello Guys,
At first a little background story:
I bought the Tablet 3 Month ago. I have got the Update to Android 6.0 in January and unfortunately, I applied it.
So If you don't want to apply a custom rom do not update to 6.0, because 5.1.1 is much better.
I am not responsible if anything goes wrong.
Ok, so let's get started:
At first you must install Minimal ADB and Fastboot on your PC/Laptop/Mac.
Windows: https://forum.xda-developers.com/showthread.php?t=2588979
Linux/Mac: http://rootmygalaxy.net/install-adb-and-fastboot-on-mac-or-linux/
Here is the link for all OSs: http://lifehacker.com/the-easiest-way-to-install-androids-adb-and-fastboot-to-1586992378
Before you can Root or flash a Custom Rom you must flash the recovery:
You will need:
-Nvidia Family Drivers(Extract it in a folder of your choice): http://nvidiashieldzone.com/files/shieldtv/shieldfamilydriver.zip not working anymore, official link:
http://developer.download.nvidia.com/mobile/shield/SHIELD_Family_WHQL_USB_driver_201801.zip
-As many of you are experiencing problems with my previously mentioned TWRP 2.8.7.3 version I am replacing the link with the official TWRP Shield Tablet Download Site. Just take the newest stable version: https://dl.twrp.me/shieldtablet/ (Put the file into the ADB+Fastboot Folder)
-TWRP 2.8.7.3 Recovery(Put the file into the ADB+Fastboot Folder): Download URL: https://www.androidfilehost.com/?fid=24269982087009777
Developer Post: http://forum.xda-developers.com/shi...recovery-twrp-2-8-7-0-touch-recovery-t3257172
Install the Drivers
Connect your Tablet to your PC
Windows:
Open your Device Manager
If there Is a device with a yellow ! klick on it and update the Drivers Manually(select the Folder where you extracted the Family Divers)
Linux:
You don't need any drivers
(For every fastboot command in ADB+Fastboot you will need a "sudo" in front of it...)
Mac:
You also don't need any drivers
(For every fastboot command in ADB+Fastboot you will need a "./" in front of it...)
Flash Recovery
1. Open Minimal ADB and Fastboot
2. Type in
Code:
adb devices
if you get a long term of numbers and letters your drivers are correctly installed, If this command does not bring up a device, check your cable connection and/or update your drivers again.

Please Leave a post if you are getting errors or something isn't clearly explained! And if I could help you, consider giving me a Thanks
Troubleshoot
If you are stuck in a Bootloop:
Without data loss(e.g. when you installed Xposed framework zip and its stuck in a bootloop)
1. flash the stock rom boot image BUT ONLY IF YOU DONT USE A CUSTOM ROM (it will probably loose root). go to https://developer.nvidia.com/gameworksdownload#?search=SHIELD Tablet K1&tx=$additional,shield and download the latest NVIDIA SHIELD Tablet K1 Recovery OS Image
2. Unpack the zip file and flash it to your Tablet
Code:
fastboot flash boot boot.img
If something went wrong while flashing a custom rom (after that you will need to flash the custom/stock rom again)
wipe the /data partition. It could be encrypted from the previous rom. Be aware that you need to reinstall the rom, therefore loose all your data. Troubleshot guide by agentbob123
-Toby
Credits:
@xsquid mac support
@agentbob123 suggestion to mention to wipe the /data partition as a solution for being stuck in a bootloop
@champs777 suggested the newest TWRP
@grävling mentioned importance of waiting until the recovery flash is finished

My tablet just keeps rebooting to the lock screen whenever I try to go to recovery mode... Somehow twrp doesn't stick... It did when I was on Lollipop. I have already tried to flash the recovery, do a full reboot before trying to get in twrp but without success.

On mac
You dont need any drivers
(For every fastboot command in ADB+Fastboot you will need a ./ in front of it...)
example being ./fastboot oem unlock

Try other TWRP versions like 2.8.7.0 or 2.8.7.1 i think the 3.0.0.0 is for Andoid 6.0 devices so if you are currently in the newest version of the Android OS try this one out
The 3.0 versionof TWRP was unstabel on my device so you should flash it wipe the storage and flash one of the older ones

How can I remove this file without root ?

Try your normal command line for flashing recovery except change flash to boot. It doesn't flash it, just boots to it.
In other words, if you are using:
1. Fastboot Flash recovery recoveryname.img
Do instead:
2. Fastboot boot recovery recoveryname.img
While in recovery (make sure the supersu zip is on the sd card or wherever you normally flash files from first) flash supersu. You should now be rooted but without a recovery.
Go then to delete the file and then reboot, flash the recovery as normal (#1), reboot and then it should be good to go. It was for me.

rooted device no need to unlock bootloader it will unlock for ittself
just go to playstore and dowload twrp manager
choose the name of your device
and choose one of the two versions available
for shield tablet the version 3.0.0.0 doesnt work well it spilts the screen but wthe other version Works great
the link is twrpmanager on play.google
this way you dont need to connect your tablet to your pc

Great work!

Thank you for the awesome guide. Besides deleting the TegraOTA apk, is there any other app/service that I should disable to prevent OTA updates?

Followed the guide after screwing my device up with official firmware. Thanks for nothing Nvidia, why are you offering OTA that cause the device to stop working correctly.
Nothing happened other than appearing to boot itself to the "powered by android" (kernel) screen over and over.
Held down power + volume UP ...
And it factory reset itself.
Somehow.
Did I mention that Nvidia is a terrible company?
Edit: Fixed using TWRP v3.0.0 - this guide should be updated to reflect this particuarly as people who screw their device up after trusting Nvidia OTA MM will be using it.

I'm sorry that you had that problem but this guide is a general guide and not an screw nvidia (besides they are awesom giving us a really good tablet for 200 Buck, but jea?) guide. TWRP v3.0.0 has his bugs so generally when you have finished deleting the stock rom you should flash TWRP 2.8.7.3 works the most stabel.

Add TWRP to M image (Shield 1.1)
Folks,
Just received Nvidia Shield K1 and OTA immediately upgraded it to M (Shield 1.1) and I unlocked bootloader no problem. However when I go to flash or temp boot twrp 2.x or 3.x it flashes OK, but when I reboot (either via fastboot or hard off/start to recovery manually) it appears it is overwriting the recovery partition and it just boots normally.
Is there a limitation to flashing twrp bootloader in M, and do I have to downgrade to L to flash recovery partition?
I seem to be happy w/ stock (limited stick time), I just want to root at this point and install my favs. Once I get this running will supersu pro preserve root, or do I need to turn off nvidia OTA process.
Also I see optimization for chrome, does this do anything X1 optimizations)?
Thanks

After you flash twrp reboot to recovery. I may be wrong, but I think the stock ROM overwrites the custom recovery at reboot. If you reboot to twrp first after flash, twrp will disable this.

Rooting
Hi everyone,
Yesterday got my new Nvidia Shield Tegra K1 and upon using it I noticed it's a great tablet for it's price range and will do my job easier while flying my Phantom 4. To be honest it's seems very stable and solid but was thinking about rooting it. I have some questions regarding the process wince I haven't rooted anything since my HTC Fire, log time ago that was. What are the benefits of rooting this device ? Will I still be able to update the Shield with its official updates ? Will I be able to roll back to an unrooted tablet should I need too ? I wasn't planning on flashing a custom rom but if I'll do what are the pros and cons of doing so ? I know that maybe searching this forum I would find all the answers needed but since there is so much information and threads I'm lost as from were to start from.
Would be nice to guide me about how to properly root my device with all the necessary links. My tab is running on Android 6.0.
I thank you so much guys for the hard work you all do in providing such information. I know it takes a lot of time and patience.

I just got a Shield K1. I like it a lot but I wanted to root it. Then I saw how confusing it is to distinguish between it and the previous model. My guess is whatever is out there that says Shield Tablet means the old one not the K1. I also updated mine to MM cause I'm using and 128GB micro sd card for internal storage. I guess I'll just have to wait until more support comes out for this tablet such as a stable TWRP 3.0 Recovery and the ability to gain root access and custom ROMs like CM 13.

do you recommed to install all OTAs before install custom recovery and custom roms or is it better to install twrp-2.8.7.1 out of the box and then go for the custom stuff ?

I would install all updates to get the latest bootloader. Do not install twrp 2.8.7.1. Install the official 3.0.x from the official site.

ME176C/CX Kitkat and Lollipop OTA UPDATE Guide + Troubleshooting

For everyone, that is unable to update your OTA files, i found a solution.
I do not have the credits myself, there was someone else that found this out, i cannot remember from who is it, but i believe it was someone on this forum.
I did find the links on 4PDA and the inscrutions aswell.
to fully upgrade KK you need OTAs - 191,198,199,201 - you need to flash them in order and flash every single one! You can flash them at one recovery session, it will update the tablet the correct way. Or you can just reboot after every single update, what suits you more.
!!! Im not responsible for anything that happens during/using these steps, you and only you are responsible to what happens, use with caution !!!
BEFORE WE START:
KK to LP update takes long time, make sure to be charged to atleast 50% of your battery! If your device powers off midway through any update, it will probably cause hard brick, making your device no more usable!
To update from KK to LP, you need to have the latest KK OTA, which is .201!
For the OTA updates, use the files from [me176c/x] [K013] Collection of ROMs and Updates - watchout for the .191 update, there are 2 links, from which only 1 is correct, .191 update should have 154MB.
There are some thing that will prevent you from updating
- root - should not prevent you from updating, i used the Root Zenfone app, from mentioned thread above, it did not prevent me from updating, but unrooted after KK to LP update
- xposed - not tested
- uninstalling system apps WILL 100% prevent you from updating (to revert that, install the .182 full ROM)
- freezing/disabling system apps SHOULD NOT prevent you from updating
For updating i used Temp CWM recovery, TWRP had some issues updating, if you get errors in TWRP, please consider using CWM.
Download the files respective to each OTA update from my google drive (Modified Update Scripts)
Extract the updater-scripts from the downloaded files to any folder and copy it
Download the OTA updates from this thread (first post)
Open update_XXX.zip\META-INF\com\google\android\updater-script with WinRAR and paste it (replace the original update-script)
WinRAR then has some options for compression and stuff, keep everything as it is
You do this to every single OTA you have - 191,198,199,201
Then move them to your internal storage on the device, or sdcard, whatever is better
power off your tablet and boot it up once again used POWER + VOLUME UP
Droid boot mode should appear, connect it to your PC
open launcher.bat inside Intel FBRL (cant share the link atm - google intel temp recovery)
follow the steps in your launcher.bat - ACCEPT, wait, 5 (cwm.zip), wait, T2 or T4 both works
Temporary CWM then should boot up on your device
make full factory reset data/cache/dalvik-cache
flash the modified OTA update from your intstorage/sdcard
when youre in the recovery already, you can flash every OTA you have, but in order - that means you flash 191, then 198, 199, 201, THEN REBOOT
wait for your tablet to finish the updates and boot up the system as normal
When you made it to .201 update (check in system settings, if thats correct), you can either stay on 4.4.2, or upgrade to 5.0
KITKAT TO LP UPDATE
download the file from official ASUS website, i used version .17, you should be able to go straight to the .36
MAKE SURE THE FILE YOURE DOWNLOADING HAS _KK (Kitkat to Lollipop) IN THE FILE NAME!
open the downloaded file, extract updater-script once again using WinRAR
(same location as before - XXX.zip\META-INF\com\google\android\updater-script)
delete the first 2 lines in the updater-script
getprop("ro.product.device") == "K013" || abort("This package is for \"K013\" devices; this is a \"" + getprop("ro.product.device") + "\".");
show_progress(0.750000, 0);
put the modified updater-script back into its original place, WinRAR asks once again for compression level and stuff, keep everything as it is
Move the modified update file to either the root interal storage or root of sdcard
your device should ask you to update in the notification bar, if it does not, try either rebooting the device or plugging/unplugging MTP cable to your PC, both should work
select the update, let it do its thing
For many things, including the modified updater-scripts, temp recovery and OTA files i used
