Yes for days and multiple

ROM/kernel combos and that's all I got.it states clearly man over and over .I forget after all why you want S-off for(was it to convert to GPE?)
[AT&T HTC One (M8)] redpoint73:
adb should work whether you are in fastboot mode or not. adb should work in any condition, as long as the phone is powered on (in OS, bootloader, recovery, fastboot).
[AT&T HTC One (M8)] LightningKitsune:
SkyDragon rom. Says you can do it s-on, but I assume it's only for GPE M8's (or at least att converted over to GPE) because 4.4.4 is a must. I'm on 4.4.2, so I have to use the S-off method unless there is a 4.4.4 RUU for att devices.
[AT&T HTC One (M8)] jxcorex28:
Well there's a RUU for GPE 4.4.4...it's 2.12.1700.1 hosted on graffixnyc.com....it's best to s-off, if you have 25 bucks just use sunshine.
[AT&T HTC One (M8)] jball:
I did the full GPE conversion just the other day and it involved the 4.4.3 ruu so I could accept the official OTA ,

Took the OTA on my (at&t) HTC ONE M8

Keep in mind I followed to the letter all steps including changing "cid" and "mid"

Choose the 4.4.4 file but it's still a must to have S-off cause you want to have matching "cid" "mid"

Hi,

Thanks for the instructions. I followed the unlocked bootloader one, but now I cant boot. I flashed the modified LTE boot img and now everytime I boot it keeps going into fastboot mode.

Unlocked bootloader

flashed CWM

Booted into CWM and flashed SuperSU Beta

Selected Yes to fix Root

Reboot system

Boot back into fastboot and flash the modified boot.img

Reboot system...............now keeps booting into fastboot.

Please help.

EDIT: I'm an idiot. Unzip the boot.img before you flash it. Problem solved.
[Shield Tablet Q&A, Help & Troubleshooting] SuperPichu:
You can also restore stock recovery afterward by flashing this
[Shield Tablet Q&A, Help & Troubleshooting] layanto:
Possibly dumb question, but is the stock recovery on 4.4.2 KK the same as stock recovery on L? If I backup the stock recovery on KK with flashify, can I then restore once I am rooted and on L?

You can definitely restore it if you make a backup. I'm actually not sure if they are the same.

[Shield Tablet Q&A, Help & Troubleshooting] KentuckyHouse:
In reading through the other thread, I can't seem to definitively find what I'm looking for.

My Shield has a locked bootloader, but I've installed the OTA. Is my only option to unlock the bootloader and then follow the unlocked bootloader root method? Or is there a way to root only (I'd like to keep stock recovery) with the OTA already installed?
[Shield Tablet Q&A, Help & Troubleshooting] SuperPichu:
You will have to unlock. You can restore the stock recovery afterward if you wish
[Shield Tablet Q&A, Help & Troubleshooting] RiffyDivine:
Does towelroot still work for the LTE devices when moving to lolli?
[Shield Tablet Q&A, Help & Troubleshooting] KentuckyHouse:
OK, so I had to unlock my bootloader since I'd already taken the OTA.

Now I'm at this point. I can't seem to get recovery to stick. I've flashed it multiple times in fastboot and it just won't stick. Now, over in the other thread, someone has asked if I've done the "fastboot flash boot boot-root.img" step yet. This confuses me, as that step comes AFTER you flash recovery, then flash SuperSU with CWM. But seeing as how I can't get recovery to stick, I can't flash SuperSU, and that means I can't move on to that step.

So I guess what I'm asking is, can I run "fastboot flash boot boot-root.img" before "fastboot flash recovery recovery.img"? Will that make a difference? Will it brick my tablet?

I'm all out of ideas here.

Root Question with Lolipop

So I just have a quick question, I just used towel root on my Shield on 4.4.2 KK, I have root access now. I want to update to 5.0 LP and gain root from there but the root method without an unlocked bootloader says to download the OTA to 5.0 but hold off on installing. I am downloading right now however I dont see an option for "Install immediately after download finishes/ Choose to install at a later date" I just want to save myself the headache, I dont want to install roms or f*** my warranty (in case I have the screen cracking issues) just want to use root apps. Anyhow thanks, I know this seems trivial but all to often I screw up somewhere when trying to follow the myriad of methods to root and recover the seemingly endless sea of devices available for android.

Already updated and no root 5.0?

Hello my Shield Tablet LTE came with 5.0 already installed and a locked boot-loader. I do not want to mess anything up if it will not work. Is there a way if you do not have root prior and have a locked boot-loader to root the shield 5.0. Everything I am reading states that we need an unlocked boot-loader or root on Kit-Kat. Having already been updated and my boot-strap locked how do I proceed to root this device or should I just buy another one and start over?

I think i did it

*wipes sweat from forehead* that went A LOT better than jailbreaking my i**** years ago (it bricked).

I have a LTE and upgraded to L on a locked bootloader. Followed the instructions to unlock the bootloader and this is what I did next:

(In the Windows console) Type "fastboot flash recovery recovery.img"

On the tablet, select "recovery reboot"

You should be now on CWM. Simply select "install zip from file" -> install from sideload

In the console, type "adb sideload supersu.zip"

So when I typed into the console "adb dieload supersu.zip" I would get error:device not found.

I ended up copying the zip to the internal storage and instead of using the sideload i did it from the internal storage and it took. I am now in L rooted (verified by running an app that requires root) and pulling apps back. I want to say thank you to everyone who has posted and the mods for helping those who have. People who ask questions and take the time to get answers do help out others just indirectly.

OTA update 2.1 (android 5.01)

I received my Shield tablet yesterday and following the instructions succesfully unlocked bootloader, updated to android 5, flashed CWM recovery, supersu, gain root and all was fine. This morning i got notification for another upgrade, LTE android 5.01, OTA 2.1. I went ahead and downloaded the update, about 85Mb, rebooted to update, and the CWM gave some error message and didnt install the update.

My question is if i can flash back the original recovery, install the update, then flash back the CWM recovery? If yes, where can i download the original recovery? Shall I keep the root? Anyone updated already to this version?

My tablet is NA LTE version.

Thanks in advance,

Is there a way to remove CWM and restore the default recovery image after following this guide?

I've installed CWM and have achieved root (locked bootloader), however I cannot update to 5.0.1. There doesn't seem to be an "nvidia" folder in the sdcard for the 5.0.1 update so I figure I'll have to remove CWM and restore a factory recovery.img to install the update successfully. If anyone has any insight as to the best way to proceed, I'd appreciate it.

Reverted to Stock

I did not want to for sake of keeping my warranty, but I had to unlock my bootloader for this.

I was able to use nVidia's 1.2.1 Recovery Image to successfully revert my tablet back to Android 4.4.2. This removed CWM and root, however I was able to update to 5.0.1 directly from 4.4.2 (~713MB download).

I had to register for nVidia GameWorks to gain access to the downloads. Took no longer than 1.5 hours to be given access. I'll gladly upload the recovery images to a mirror site if that's allowable here. They're around 2.2GB each.

I'm assuming the initial method for root will work after flashing to a pre-lollipop release.

EDIT: Well now the OTA zips are being discovered so those should work just fine for updating.

[Shield Tablet Q&A, Help & Troubleshooting] CM17X:
You won't be able to update via OTA if you're rooted.
[Shield Tablet Q&A, Help & Troubleshooting] Vankog:
Might this be, because of reports that Lollipop might with future OTA updates check and patch the whole partition instead every single file?

If this is the case then any changes in system partition would break any future OTA updates.

Unfortunately this also means that keeping root during a Lollipop update with locked bootloader is only possible when coming from a version below Lollipop, doesn't it?

You're right, new updates will check for the partitions and stuff.

Unlock developer options by tapping build number a few times in settings. Go to developer options and enable USB debugging.

Search for and download minimal adb/fastboot and save to desktop. Make sure all the drivers are up to date as well. Also, make sure you download the NVIDIA shield adb drivers from the actual website. Find those two things, and you have your first steps done. when you download the NVIDIA shield adb drivers, you will receive it as a ZIP(make sure you have winrar) extract the zip to the desktop and you should have some files. Go to device manager, find your device, and manually search for the drivers on desktop. Now, your MTP USB should allow you to code **** into the tablet.

After that, you will need to download a CWM image and the latest version of SUPERUSER zip. Google for those things. Once you have those things, put them on desktop for reference and go to your computer > program files and find the minimal adb/fastboot folder. COPY the recovery.img to the folder and also rename the superuserzip to su.zip or supersu.zip. (you will know why later) Run as admin for the mini adb/fastboot on your desktop. A coding window should show up.

From here, type "adb reboot bootloader" and accept USB debugging on your tablet. If it worked, your tablet should be at a reboot tab. Use the volume rocker to move up and down. Select load fastboot protocal and power button to confirm. In the computer, type "fastboot oem unlock" On tablet, select Unlock bootloader. Now, type "fastboot flash recovery recovery.img" To open CWM. Select install zip, install from sideload, then type "adb sideload su.zip" or whatever you renamed it to. Make sure you read the coding **** on windows. Once done, go back and reboot. Keep root.

Thank you so much for the .doc file. I don't intend to sound rude, but this is how instructions should be written every time a new firmware releases. I was frustrated with links taking me to other links and I was totally confused... especially since I am new to the android eco-system. Don't think a towel-root for 2.0+ firmwares is ever going to see the light of day unfortunately. Towel root was like jailbreaking an iOS device... a couple of clicks and you are done! I hope someone comes up with a one click rooting tool *wishful thinking*

Anyway, coming to the point... nVidia released 2.1 factory images last month. I have purchased an LTE version from the US which is still on 4.4.2.

1. Should I download the US LTE 2.1 factory image or the RoW 2.1 factory image?

2. I want to completely format my device and start from scratch... will these steps work for 2.1 as well? Or do I have to look for update CMW and SuperSU links?

3. Will future OTA work? or will I have to root every time an OTA is applied?

4. This one is more to do with Lollipop itself... How is Lollipop 2.1 (Wifi/Gamestream/Battery) compared to KK 4.4.2? Is it worth upgrading?
[Shield Tablet Q&A, Help & Troubleshooting] SuperPichu:
I somewhat disagree with this just because if you can't do the prerequisites, you probably shouldn't be rooting in the first place. My instructions were written to use that as a barrier to entry as well as an opportunity for new people to learn.

All that being said I must agree the document was very well written even if it did cause a few driver problems for people.

As far as your questions:
