[Shield Tablet General] remydlc:
Actually, going to do it here as it might help someone else. So yesterday I downloaded the FW from other thread, and it did not help, the files were named differently, so i didnt dare to rename them and flash them to my tablet... I just dont know what they were and wasnt going to play with it.

So i went to the NVIDIA site itself and downloaded the previous OTA from March. I dont know why they didnt have the newer one. I didnt care since i was going to do the OTA, which immediately showed up, about a 24-32MB OTA:

https://developer.nvidia.com/gameworksdownload#?search=SHIELD%20Tablet%20K1&tx=$additional,shield

Expand the "NVIDIA SHIELD Tablet K1 Recovery OS Image " by clicking on ">" and then choosing the download for any OS: Windows or Linux, all the same. Once you finished downloading file "nv-recovery-sb-na-wf-1.1.1.zip" extract it. Open your command line and go into this folder. I am assuming you have Developer mode's USB debug enabled and ADB installed. If not, feel free to browse the NVdia site around as they have the adb and other windows drivers that you might need.

Once on the command line, this is what i typed: NOTE!!!!! I restored my recovery to stock! If you wish to keep TWRP, feel free to skip the first command below or type it after you get the OTA. I am just tired of AOSP roms slowing my tablet down. and going to keep it stock for a little while.

$ fastboot flash recovery recovery.img

$ fastboot reboot bootloader

$ fastboot flash boot boot.img

$ fastboot reboot bootloader

$ fastboot flash system system.img

$ fastboot format userdata

$ fastboot flash staging blob

$ fastboot reboot

Done, feel free to setup your accounts, and right after you boot, you will get the OTA update to the latest update.

Hope this helps.

thank you Sir but i am running this rom http://xdaforums.com/shield-tablet/general/unofficial-update-original-shield-t3281541

and i don't haveSHIELD Tablet K1, I have old wifi

should i do everything same except use this recovery https://developer.nvidia.com/gameworksdownload#?search=NVIDIA%20SHIELD%20Tablet%20WiFi&tx=$additional,shield

and flash full OTA FROM FIRST PAGE :D
[Shield Tablet General] remydlc:
the concept is the same. Remember, the steps i gave you are to restore back to factory settings (unless you dont flash the stock recovery and keep TWRP) then that is going back to the stock FW. You can use the one posted on the OP, or browse the nvdia site for the original Shield Tablet Wifi.
[Shield Tablet General] Rackers:
I've just installed the update using the latest recovery 4.0.1. When I go into settings it still shows version 4.0, is that right? (Wi-Fi version).

Thanks
[Shield Tablet General] drewski_1:
That's what i see (4.0) after flashing 4.0.1 RoW on my LTE version.
[Shield Tablet General] Mr_Armageddon:
Have gone through this thread, but still not clear on the OTA upgrade process if already Rooted.. Currently running Stock 5.1, rooted, and TWRP and my LTE enabled device. Is the order of these operations correct?

- Flash Full OTA update (4.0 RoW LTE) via Recovery

- Flash SU zip via Recovery to enable Root

- Flash MM Bootloader via Recovery.

Does that look correct? Thanks in advance for anyone's help.
[Shield Tablet General] meowone:
If you flashed the full OTA file, then the bootloader is already included. You will need to update your TWRP to the MM compatible version using fastboot after flashing the OTA and then flash SuperSU to re-root. That's the step that I followed.
[Shield Tablet General] MiePx3:
Hey guys, I hope its okay that I ask in both threads, but I kinda confused here.

I have a old Shield Tablet with noota installed. Now I want flash the latest recovery image 4.0.1. Is this save to do so?

Im not sure if the "kill switch" is already in there and only triggered on old devices. So I ask here!
[Shield Tablet General] Rackers:
I've flashed the latest recovery image two times on my original Wifi tablet, just make sure you run the nomoreota.zip in TWRP before you even boot.

for unlocking the bootloader:

'fastboot oem unlock' does not work. must use sudo: 'sudo fastboot oem unlock' only then it works. (on linux)
[Shield Tablet General] skyman88882002:
I read through the threads but I am still a bit confused. I have the Shield Tablet K1, running Android 5.1.1, rooted and TWRP. I want to flash to the latest version of marshmallow. Do I flash the full OTA update 4.0 with TWRP? The download is called "productionBL-droid-sig…1040949.zip" and is 713MB. OR do I use adb to flash the Wifi recovery image 4.0.1 which is like 2GB with fastboot?? confused.

Edit. Nevermind, just flashed nvidia recovery image and it worked fine
[Shield Tablet General] Lifeis4real:
Is there any 4.0 Ota full for the tablet lte (usa) I'm using cm 12.

Also In regards to flashing would I just have to go to recovery and flash?

Looking forward to your reply guys.
[Shield Tablet General] drewski_1:
US LTE has gotten no love.

Just use the RoW version. It's working great on my tab.
[Shield Tablet General] gqukyo:
You can download and fastboot install 4.1. There is no 4.0 for the NA LTE version
[Shield Tablet General] MidgetMob:
I've been extremely busy so I apologize, however:

4.1 recovery images have been added

4.1 full OTAs have been added

TWRP links have been added for most recent versions

If anyone has any of the following incremental OTAs or has links for them (if they exist), I kindly ask that you share them so I can add them to the post:

3.1.1 to 4.0

3.1.1 to 4.0.1

4.0 to 4.0.1
[Shield Tablet General] tux_topo:
Most probably an stupid question.... but is possible to flash the stock original img using the newest twrp 3.0.2.2?
[Shield Tablet General] gqukyo:
Yes you should be able to
[Shield Tablet General] tux_topo:
Some how to?
[Shield Tablet General] gqukyo:
If your taking about the kernel, just extract boot.img from whatever firmware file you want to flash and select flash img instead of zip in twrp.
[Shield Tablet General] tux_topo:
I was talking about the recovery full img from nvidia... or at least the system and userdata....
[Shield Tablet General] gqukyo:
Yeah, just go download the full OTA zips and flash
[Shield Tablet General] arty_anikey:
Can't flash 4.1 full ota (LTE RoW) with latest twrp (flashed via fastboot). It hangs forever on "Patching system unconditionally". Anyone having same trouble?
[Shield Tablet General] gqukyo:
Could be bad download, download it again. If the hash is different then one of the files, or both are bad. What is the exact name of the file you're flashing?

Can I flash this in TWRP? What do I flash after to retain root?
[Shield Tablet General] enfuzor:
Thank you for posting this! Flashed in TWRP without an issue and then retained root just fine flashing SuperSU.

On a Shield LTE that's been flashed to RoW instead of staying on the US build (which is still continually delayed by AT&T in the US).
[Shield Tablet General] p3dboard:
Also flashed my pyro tab (y01 battery tab that I got off ebay) with latest 4.2 update, flashed NoMoreOTA.zip, latest SuperSu stable, and TWRP 3.0.2.0 (just incase twrp was replaced).

Placed tablet in Airplane mode first before doing the flash (safer incase OTA tries to push for my pyro tab).
[Shield Tablet General] JohnK71:
Does anyone have the WIFI version yet? I would rather flash that instead of the LTE version, thanks.

Thank You!

Thanks!!! Worked!

Just had to make sure and flash SuperSu afterwards. TWRP remained in tact!
[Shield Tablet General] gluca78:
TWRP you used to make the flash? and then you put SuperSU and deleted folder tegraota, right?

Inviato dal mio D6503 utilizzando Tapatalk
[Shield Tablet General] stunned2:
I did not delete anything. I followed directions on page 1. The only difference is I used the latest TWRP available from their TWRP app to flash and wiped cache and dalvik/art within TWRP. I then immediately flashed the latest SuperSu zip available from the SuperSu website and upon first first boot there was one boot loop which SuperSu already warns about in their documentation and the new 4.2 booted rooted. It did not quite finish booting a few times but in my experience I have xposed installed as well and once I went back into TWRP and flashed the most recent xposed zip all was well. :)

Hope this helps.
[Shield Tablet General] gluca78:
Thank you. my fear is that the tegraota was inserted again and the killswitc hitting my tablet. So just do the flash with TPWR and enter SuperSU. I already have the latest version of Xposed, so there is no need to uninstall and reinstall it again, right?

Inviato dal mio D6503 utilizzando Tapatalk
[Shield Tablet General] gluca78:
I did it. Fortunately I had set the air mode because after upgrading the tegraota folder was back and I had to manually delete it (the nomoreota script did not work), so my pyrotablet does not risk the killswitch (hopefully). Thank you all for the advice.

I mean, depending on the cause of the issue (network speed, host limit) you could request a mirror on another host...

Best guess would be to reflash the framework. Does the app say it's installed?

You may need to uninstall some system apps like Trine.

Then the cause is this? I did not believe that the 4.2 compared to 4.1 occupy all available space.

[Shield Tablet General] gqukyo:
Apparently enough that you can't install xposed...
[Shield Tablet General] MidgetMob:
I've installed from an SD card so that isn't the factor. You could very easily check the free space on the main partition from within the OS. I suggest you confirm the lack of space by doing that first.

If you do indeed have free space, I vaguely remember an issue with permissions in TWRP causing an error like this but I cannot confirm that. You'll have to browse the forums more for a solution if that's the case.
[Shield Tablet General] gqukyo:
I've always had issue in the past installing xposed on the stock roms so I've always deleted system apps before I even attempt to install xposed and it has never failed for me after that. If anyone else just installed xposed on the stock rom without deleting any system apps then let us know.
[Shield Tablet General] Isira:
You do realize that romracer's TWRP is outdated. The definitive TWRP build at this point is the Official TWRP 3.0.2-2 as it supports all bootloaders and fixes the touchscreen delay bug that had been plaguing all previous 3.0 builds.
[Shield Tablet General] MidgetMob:
Good to know, thanks.

How do I upgrade to OTA 4.2 RoW?

I downloaded the full OTA for RoW. Uncompressed the zip file and I see the files have different names and formats... weird...

Names:

META-ING (folder)
blob
boot.img
file_contexts
system.new.dat
system.patch.dat
system.transfer.list

According to Nvidia's tutorial they sould have these names:

recovery.img
boot.img
system.img
userdata.img
blob

Was I supposed to flash the ZIP???

---------- Post added at 09:02 PM ---------- Previous post was at 08:17 PM ----------

I have solved the problem.

I had to manually flash the zip and now it's working.

RoW and WiFi 4.2 recovery images added
[Shield Tablet General] ThePhoneGeek:
I am just coming back to the Shield forums as I've been away since I gave the shield to my wife (ver 3.1.1 I think).

Device is currently rooted with TWRP(old) and here is what I was hoping to do.

1) flash the current twrp.

2) flash the full 4.2 in twrp.

3) flash the current Supersu.

Does this work or do I have to completely wipe it and load the full 4.2?

Thx!
[Shield Tablet General] aaronne:
Hi if you are on Lollipop you must flash by PC from adb fastboot (because the blob's change) with original shield's image or manually flash blob stage and then proceed by twrp's way (also explained somewhere here at xda forums).

Regards
[Shield Tablet General] Isira:
Yes, this works.

1. Flash the current TWRP 3.0.2-2

2. ADB sideload the Full OTA zip within TWRP.

3. Flash SuperSU 2.76

I can't remember, but I believe if you directly flash the ZIP in TWRP, you lose TWRP, but if you ADB sideload, then TWRP stays. In any case, if TWRP gets replaced by the stock recovery, just reflash TWRP.

No need to do that, that is what the Full OTA is for. I have successfully upgraded from Lollipop to Marshmallow by simply using the Full OTA zip without needing to wipe my device. The Full OTA's contain the latest blob already.
[Shield Tablet General] GuyInDogSuit:
Once again, I flashed the full OTA update, rebooted, and everything was just ****ed. I don't understand why I always end up with constant app crashes and stuff just not working, with EVERY update. So I'm forced to clean flash. Is it only me? I don't even have mods like Xposed and such installed. It's all stock. Not that Xposed freakin' works, anyway....
[Shield Tablet General] Isira:
According to this post, you were running the US-LTE 4.1 ROM. I assume you attempted to upgrade to the RoW-LTE 4.2 ROM. From my experience, using a RoW-LTE ROM to upgrade an installed US-LTE ROM will break things and require a reset. The home button was missing, power button menu was missing items, notification bar was broken, apps crashing.

Now that you're on RoW-LTE, at least you'll now be on a faster update path rather than having to wait months for AT&T to approve any update. Using a full RoW-LTE to upgrade an installed RoW-LTE ROM has been flawless in my experience (From Lollipop to Marshmallow, Marshmallow to Marshmallow).
[Shield Tablet General] GuyInDogSuit:
Actually, that wasn't the case. I just realized I posted in the wrong thread. I flashed an "optimized" LTE US zip. I didn't have the problems you described, just certain apps repeatedly crashing. Like Archos Video Player, Titanium Backup, etc. Cleared app data, still happening. Uninstalled, reinstalled, crashed upon opening. So I don't know what the deal was.... Regardless, since what you say about the RoW-LTE variation is true, I'm gonna wipe and flash that one from this thread instead. Zipaligned sounds great on paper, but I'm not sure it was worth those issues.
[Shield Tablet General] Isira:
I assume you flashed this ROM, which is RoW-LTE-based, not US-LTE, so you demonstrated that US-LTE -> RoW-LTE upgrade is problematic and requires a reset.

Another user successfully upgraded their RoW-LTE to 4.2 using that zipaligned ROM with no issues (Post 1577-1582), which demonstrates RoW-LTE -> RoW-LTE upgrades are safe.
[Shield Tablet General] GuyInDogSuit:
No, I flashed the one in the first post, which is US LTE, is it not? I know that the regions aren't compatible, and I don't think that was the cause of the app FCs. The launcher, notification bar, and so on worked fine.

I know they are safe. Of course they are. As long as it's the same region, it's compatible. You're assuming that I flashed the wrong region zip. Fairly sure I didn't.

Anyway, now that we're past all that nonsense, it seems that I had to delete some system apps to make room for Xposed. Really odd. Restoring my apps now. Hopefully Xposed actually works with mods installed this time.....
[Shield Tablet General] Isira:
The first post is the same file, where the LTE ROM is RoW (The URLs of the direct file download are the same). Another hint is the date of the upload August 18. The US-LTE 4.2 ROM was only JUST released OTA yesterday (August 23).

Anyways, I hope Xposed finally works for you :good:
[Shield Tablet General] JogibaerNr1:
Ok I think I'm the 12099503459 person who is a bit confused about the update process. Is it possible to update my 4.1 MM Shield US LTE (rooted, Supersu and TWRP installed) to 4.2 US LTE (with root and TWRP) without losing my data and all installed apps? :silly:

The last times I tried this, always ended up that I had to wipe everything on my Shield. :rolleyes: If it is possible, what do I have to do? I've read so many manuals and threads but it seems that every manual is a little bit different. However, I've to wait for the 4.2 US LTE image download. Can someone help me please. :)

P.S.: I'm shortly before wiping everything back to stock and using my Shield without root again, so it's easier to update Android. But this would be a pitty because I need the sd card write access for some apps.
[Shield Tablet General] Isira:
Yes, you should not lose your data when you upgrade with the full OTA, but you will need to reflash root. You also might need to reflash TWRP as the upgrade process sometimes replaces it with the stock recovery.

Assuming your tablet is not the recalled one, go to Settings -> About tablet -> System upgrade -> 3 dots -> Advanced -> Check full upgrade. This will download the full OTA and allow you to do an inplace upgrade. Then flash TWRP and root.

Restoring Sheld Tablet K1

Hey I've bee following this guide up to the point where you actually do the flashing via fastboot.

I have downloaded the recovery images for the K1 tablet from the nvidia shield download site and I cannot find the following files in the which you have mentioned in your instructions:

fastboot flash userdata {dir}/userdata.img

fastboot flash dtb {dir}/tegra124-tn8-p1761-1270-a04-e-battery.dtb

Do you whether these files are needed for flashing the K1 tablet and if so where do I get these from?

Thanks
[Shield Tablet General] MidgetMob:
If they're not in the package you downloaded then I wouldn't worry about them. These guides are not for the K1 as I do not have one, so I'd be wary about using them if I were you. You could simply try running the .bat file contained within the K1 package you downloaded just to be safe. You'll have to reflash your custom recovery after using the .bat, if you're currently using one.
[Shield Tablet General] MidgetMob:
I guess the first question is, are you still running android 4.4?
[Shield Tablet General] Singularity_iOS:
I'm currently on 5.0 out of the box and I'm trying (assuming 5.0 is rom version 2.0) to use the incremental updates to go from 2.0 to 2.2.1 (in order) but I am receiving the same error.

As a side note; is xposed module not compatible with the Android version or this tablets cpu?
[Shield Tablet General] trixt:
i am not running 4.4 and if i check for a update it asking me to go 2.2.. and i know how android L looks like.. so i believe the CWM needs to be updated or something like tat...

I dont think its CWM, because i'm using TWRP and im getting the same thing. See below.

Have You Checked Your Downloads?

This may not be helpful (or it may) but for those having problems, have you checked that your downloads are correct? Are you downloading to PC and then transferring over? Have you tried re-downloading to eliminate a bad download as a potential source of error?

It may be obvious, but a corrupt download is probably the single biggest source of errors.
[Shield Tablet General] Singularity_iOS:
The downloads are fine and from what I can understand something is telling the zip install that the tablet has 4.4.2. But I could be wrong because don't know.
[Shield Tablet General] duckingzebra:
first of all great thread, i just used it to go back to kitkat. Now to my question. I tried flashing TWRP over my CWM recovery many times, but everytime i go into recovery its still CWM. Is there something im missing?
[Shield Tablet General] MidgetMob:
For those having trouble with incremental OTAs: I believe this issue is due to being rooted. The forums can explain why in a lot more detail than I can. With that being said, sideloading a full OTA might work. Flashing a recovery package will definitely bypass this problem.

1) As an FYI, your TWRP is v2.8.2.0 and the newest is 2.8.5.0.

2) TWRP is reporting your build number to be that of OTA 1.1. Just to make sure, can you check "Settings -> About tablet" and post your build number?

3) Xposed has worked fine since 4.4.2 for my device. You'll need to download the alpha versions from XDA though as the current stable builds will not work on 5.0+.

Sometimes flashing the recovery does not stick, as you seem to have experienced, and you'll have to flash it a few times in a row. Personally I have not had much experience with this issue, however if you cannot get the recovery.img to stick, you might want to try either flashing a recovery package or doing a simple factory wipe. You'll want to back up any necessary personal files before doing so, for obvious reasons.

I agree, and this is exactly the reason why I linked a file with all of the MD5s lol.
