So I got this Tablet a few days ago and wanted to get root. It came with the 3.2 update already installed so I read around and saw I needed to downgrade the os, root, flash recovery, then flash a rom via recovery.
I plan to install this rom:
http://forum.xda-developers.com/showthread.php?t=1290318
It is basically stock acer 3.2 with root. Which is all I really want.
I followed method 2 here:
http://forum.xda-developers.com/showthread.php?t=1276227
After booting and installing the unstable version to be able to get root, then I did the adb push for cwm and itsmagic. Wasn't sure what to do after this so I rebooted. (I tried downloading the acer recovery installer but my market would not let me type anything in with all the force closes)
So after reboot I am unable to get adb to show it as a listed device and everytime I try to copy the rom over I need I get an error "Cannot copy *filename* The device has either stopped responding or has been disconnected"
In frustration I figured I didn't get cwm installed properly so I downloaded the apk from the web and installed it via dropbox. It let me apply it and actually boot into recovery.
I powered off and tried getting back in but my pc still fails to see the device listed in adb or save files to it via the basic windows file explorer.
I'm currently letting the update install itself (I flashed back the original recovery via acer recovery installer) don't know if this will fix it.
If anyone can help, it would be much appreciated.
Update:
It upgraded me to 3.1 but I still can't save anything to my tab (atleast the fc's are gone). It doesn't list anything on my tab just shows 0 files. Not sure how to get this fixed.
Update:
I did a factory reset. Now it detects it and I'm able to save the rom to it. I did the root, and flashed cwm thru acer recovery installer. (avoiding adb entirely). However when I'm in there now it says "E:Can’t mount /sdcard". Read some folks are throwing it on a usb drive and flashing it that way.(BTW I put the rom zip on the root file directory, not on the external SD). Will update if it works or not.
*RESOLVED*
Got it working. It installed off the USB thumb drive just fine. Was able to install the 3.2 root Rom mentioned earlier. Everything is working as it should. Able to read and write to and from the device now. Showing superuser in my apps. Now to start removing the crap Acer put on there
This is just in case anyone runs into the same problem. Took a few hrs but its working nice
Basically I suggest this if you wish to just install the the 3.2 stock rom via cwm
1.) Since the unstable flash doesn't clear your data, download and install everything you will need first. ex: Acer Recovery Installer, Iconia Root. Put the rom on the root drive and/or a thumb drive.
2) Flash the downgrade.
3) Run the Iconia Root tool.
4) Run the Acer recovery installer (since you'll have root now) and reboot to recovery
5) Flash the rom. If it doesn't detect it try it on a usb thumb drive. Done
I always put my ROMS on an external microSD. That is the only thing I use my SD card for, and as far as I can tell is always the recommended place to store your ROMS for updating. In the root of the microSD card.
Glad to hear you got it working though.
Received the update today but it failed to install. I'm running the stock rom KRT16S. My Nexus 10 is rooted and my recovery is TWRP 2.6.3.1. I have added nothing else to this rom except a few apps from the google play store. I wanted to try again but couldn't find where the OTA is stored. It wasn't in the /cache/fota folder. So I downloaded a flashable zip from the net. But this update file failed to install also. I've seen a few others have success installing the update. I just don't know what's preventing me from updating. I welcome your suggestions. Thanks.
Same here on my Nex5.
It seems, that some custom zips changed my stock (rooted) rom in this way that I am not able to install the 4.4.2 update.
I got similar issue on my Nex4 in the past, I could help me out by flashing full rom (rooted) deodexed, but where can I find the full rom of 4.4.2 for my Nex5 now?
Anybody can give me a clue?
Thank u very much.

Hi Fred, and greetz from Ohio. I'm not aware of anything in the 4.4.2 flavor right now for the Nex10. I'm not sure about the Nex5. I think we're just going to have to wait. But I'd like to have the same thing. A lean & clean deodexed stock rooted 4.4.2 rom with a few performance tweaks. Like the old "Cleanrom" by scrosler. As for right now, did you try an ADB Sideload update to 4.4.2 using Wug's Toolkit? http://www.wugfresh.com/faqs/how-to-update-ota-not-working/

Hi,
You can try performing a full unroot in the SuperSU app if it still doesn't work... I had to adb sideload mine to work, don't know how it works with toolkit, but you have to first set your tablet to receive it. As you are on TWRP you simply go to advanced and select adb sideload, then try using the tool, or following the instructions on it to do so .
You cannot install a OTA zip like a Custom ROM zip, they are a little bit different hehe.
Hope this helps,
~Lord
PS.: This will work for N5 too.
I somehow got the idea that rooted Nexus devices with a custom recovery could handle OTA's without trashing the recovery. I guess I expected that I would lose root. I think I'm just going to wait for someone to put together a "CleanROM" based on 4.4.2 or newer. I've been waiting for a rom like this since I bought my Nex10 anyway. I don't think I'll suffer too much running on 4.4 until then.
Thanks to those who contributed, I'll remember your suggestions. Especially if I end up waiting a long time for a 4.4.2 based Cleanrom.
Update: Thanks to Wug's toolkit. I'm now running 4.4.2..
I should ask for a sticky for this but these instruction will work EVERY TIME if you are running either custom recovery or Root.
You will need the latest adb/fastboot from google, you can either install the SDK or download any of the many smaller adb/fastboot and libs for your os
You will need STOCK 4.4/4.3/4.2 recovery depending on what version of android you are currently on. Download the factory image from here. Open the zip within the package and pull out recovery.img and rename it stockrecovery.img
Copy your custom recovery to the adb folder name it twrp.zip or short name for whatever you are using I am using twrp.
You will need the correct OTA you are seeking to apply - rename it to something short simple and obvious - for this example I will use otaupdate.zip
If you wish to root get the latest patch (I believe its up to 1.75 now) and copy it to the adb/fastboot folder.
BACKUP YOUR DEVICE FIRST AND COPY IT TO YOUR PC
If you are already Rooted:
If you are using SuperSU - go to the application options and completely unroot and reboot if needed
BACKUP YOUR DEVICE FIRST AND COPY IT TO YOUR PC
If not rooted start here:
I am assuming most of you are Windows users. Open your file explorer and open the ADB folder.
On the left hand folder where ADB is located press shift and right click the ADB folder and select "Open command window from here". This will open a command prompt window for you to run all your adb/fastboot commands from. This is the same folder where you copied your recoveries and updates to.
BACKUP YOUR DEVICE FIRST AND COPY IT TO YOUR PC
Copy your custom recovery and stock recovery to your adb folder
Copy and rename the OTA to the adb folder
Copy your root.zip patch to the /sdcard downloads folder (if you wish root)
>adb reboot bootloader
>fastboot flash recovery stockrecovery.img
>fastboot reboot-bootloader
Go into recovery and wait till dead droid appears
Press power and Volume Up at same time to go into the stock recovery menu
Using the volume buttons move and down the blue list of options and select: Apply update from ADB
You will now have orange text at the bottom of the screen - follow the instructions to side load by typing >adb sideload otaupdate.zip in your command prompt window
Wait and watch the progress, at this point you should see the ota processing steps of which there a few and will vary depending on the package. When its complete there will be a "install complete" or similar message
Reboot and let the update complete the system optimizations and go in validate your device is working and the version is what you wanted
>adb reboot bootloader
>fastboot flash twrp.zip
>fastboot reboot-recovery
Using your newly installed custom recovery you can now apply zips/root etc
Reboot as needed and update root if using older .zip to current binaries and enjoy your updated device.
And yes you only need to backup once prior to starting but many people skip that step -DON'T BE ONE OF THOSE PEOPLE.
Hopefully I've not missed a bit.
You can also use these same instructions if you're stuck in boot loop or applied a patch without first replacing stock or unrooting - just boot to bootloader using fastboot and replace recovery and apply the patches. This will usually work just fine and prevent much heart ache on your part.
Hi everyone!
I have come to a slight problem, trying to flash an android L preview port for my N4. I rooted properly, but when CWM asked me if I wanted to fix boot, I unfortunately replied with Yes. After I lost my root, I tried rerooting, when I accidently selected a wipe all function. So, now I have no rom Just a CWM recovery.
I have downloaded a tar.gz factory image file for N4 (4.4.4) and tried adb pushing to the device. The transfer is successful, but when I try to install it from the sdcard (cwm), it reports failure. I googled and read a lot, but not much seems to be helping.
I am using a Mac, btw.
Thanks in advance!!
You cant install a .tgz via recovery. Instead you should download a flashable .zip of your rom. Try this.

Yes, I keep trying to do that but without success.
O tried factory kitkat zip and I tried an L android I downloaded.
Could you provide me witha link to a flashable zip?
Then tell me what you want. A factory image or a custom rom. I would recommand you cyanogenmod. Downloaf the zip for your device. http://www.cyanogenmod.org/
To install stock do this:
Extract .tar.gz (using 7Zip) until you come up with folder named "occam-xxxxx"
Copy the files within it to your fastboot.exe folder
Reboot into boot-loader
Hit flash-all.bat
But you may download latest CM from https://download.cyanogenmod.org/?device=mako and install it via flash .zip in CWM (however I recommend Philz Touch Recovery)
I'd like to flash Nexus 4 port for Android L. I had downloaded android l zip file but when I try to flash it, installation aborted keeps popping up.
And once again, people keep mentioning fastboot.EXE and run a batch file, but again... I am on a Mac. It would mean a great lot if the instructions given were for a mac.
Thanks!
Here's what I did:
1. Install Wugfresh's NRT (search online for it)
2. Download the factory image from the Google website
3. Connect your phone in Recovery mode
4. Open NRT and let it update if it has to
5. Hit "Flash stock + Unroot"
6. The usage is clearly explained at every stage. You should ideally have no problems restoring your phone to a working state. Your data however is most likely lost. Sorry.
(PS: I don't usually recommend toolkits because they take away the fun in messing with the phone manually, but sometimes it becomes necessary to use them. This is one of those times )
I tried flashing CM 11 snapshot M8 release, but it gave me status 7, install failed. I tried to fix it by removing asserts and rezipping, and failed again, without a status.
I am trying to revert back to stock now, nothing else works, and neither will this, so it seems.
EDIT:
I flashed new bootloader and new radio, but when I tried to flash a stock rom, it failed again.
I don't know what to do anymore, I feel like throwing a phone against the wall and just getting a Nexus 5.
to flash the n4 L port, download the zip in the port thread and flash it in recovery. that's all. wipe before you flash.
there was no official L preview for the n4, so you can't flash it from the factory IMG, that's for the nexus 5.

Cwm reports unable to mount... i updated to 6.0.5.0 cwm, changed to twrp even using fastboot... But nothing is helping.
Hi,
here is the situation with my Nexus 4:
* Android 5.0.1
* rooted
* TWRP
* can't access via adb while in bootloader (I tried everything I found over the Internet... uninstall/reinstall driver, tried another port, another computer, another OS, etc.)
* device not recognized when I use the "ADB sideload" option of TWRP (In Windows device manager I see "Nexus 4" with a yellow mark but I haven't been able to find a driver for it)
I want to upgrade to Android 5.1.1 (and won't go further), but how?? since I can't do the OTA update (because of TWRP) and I can't flash the Google official image (since I can't access while in bootloader)...
I don't care if I need to wipe everything, my backups are up-to-date (nandroid + Titanium).
Does anyone has an idea?
I can access to my device from Windows via ADB commands only (not convenient but it works).
Thanks a lot.

thanks for your help. Before I saw your post I used Skipsoft toolkit. Seemed to work but now my device won'T boot, it's stuck in the lolipop animation boot. I switched it off many times, but still stuck. Maybe I should have used wugfresh toolkit. I'll give a try later. Thanks again.
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)

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

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

3.0.0.0 wasn't out yet when I did mine but it was doing the same thing and this worked perfectly:

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.
