I've just tried TWRP 3.3.0-0. With that version, I can use my SD card formatted as internal storage in TWRP :)
[Shield Tablet Original Android Development] drewski_1:
This is a couple months old post, but wanted to confirm that I can access my "portable storage" formatted SDCard for backups in TWRP with no issues.
[Shield Tablet Original Android Development] Ozark_8125:
Hey all - I have a bit of a problem, it's not TWRP caused, but wondered if there's a way to run a 'low level / non quick' format data on this device in twrp? I have three shield tabs and 2 of them format data within a few seconds, but one has always taken 15 minutes or longer. Format data finally completes on that device, but it seems like the regular format data command in twrp's gui isn't scrubbing deep enough (I assume it's just wiping the fat tablet or the android equivalent of quick format in the windows system) and I wanted to see if a low-level format might clear the error. Wasn't sure if toggling -rm vs -rf formatting in settings would be the key or not.

Hello,

Is there a way to enable F2FS in TWRP 3.3.0.0?

Thanks!
[Shield Tablet Original Android Development] john_matrix:
No? Yes? Maybe? :D
[Shield Tablet Original Android Development] drewski_1:
Yes, but you may have to do it yourself¿?

Hi team,

I've broken something and can't, for the life of me, figure out how to fix it.

I've got 2 Shield Tablets, one I tried to update TWRP via the app and the other in recovery mode (they were different versions of TWRP on each tablet). The one via recovery mode worked fine, the one via the app didn't. I now can't boot in recovery mode at all. I then reflashed the latest TWRP via PC, ADB said it was successful, but still won't reboot into recovery, just hangs on the NVIDIA logo.

Any ideas?

It still boots into the OS, but I wanted to update the OS to Lineage, hence doing TWRP first.

EDIT: 2 hrs later (such a waste of time)... I used the Play Store app to attempt to reflash the oldest image available for my device (v2.8.7.0) and it worked. Never using the app again.
[Shield Tablet Original Android Development] Lorby87:
I have the same issue! Installed TWRP from app to recovery and boot and it hans on the logo screen....Now I cannot access the OS. I can boot to fastboot and status of Device shows unlocked.

I tried to flash through PC with ADB but in the command prompt says "waiting for device". In device manager in Windows I can see the tablet as Other Devices--> Fastboot.

Can pleases someone help to resolve my issue?

Thank you

EDIT: Managed to flash TWRP version twrp-2.8.7.0-shieldtablet. The issue was whit drivers on PC in Device Manager. I installed then manually "Android Composite ADB Interface" and then did fastboot devices command in CMD and it found the device.

Then I flashed the 2.8.7.0 to recovery and it loaded. Now just have to figure out how to remove it from boot so I can load the OS.

EDIT 2: Still haven't been able to find the right boot.img. Downloaded the original Nvidia boot.img but still hang on logo screen. Does anyone know if I instal a new ROM (OS) will it override the boot img?

EDIT 3: Downloaded [ROM][UNOFFICIAL] Lineage 15.1 for Nvidia Shield Tablet OMX Fixed Camera Fixed and tried to flash with no success. Fund an issue with Updater process ended with ERROR: 7. I tried to fix the problem with updating TWRP to twrp-3.3.1-0 but it hang on logo screen.

Then I went from bottom to up and the only stable version of TWRP that loaded in recovery is twrp-3.1.1-0-shieldtablet. I tried to flash the ROM and the same error apered ERROR: 7. Any ideas what to do?

Hi [MENTION=1416222]Steel01[/MENTION]

Can you please tel me wich specific fastboot command you issue to get the bootloader version of the shield?

Thanks

[EDIT] found it at the top of the screen after rebooting to bootloader (adb reboot-bootloader)
[Shield Tablet Original Android Development] john_matrix:
Hello [MENTION=1416222]Steel01[/MENTION],

There are some updates in your Gitlab repo concerning the Shield Tablet (and in the LOS17.1 & LOS18 branches).

Does it mean we can compile a build from it? or the HW acceleration is still broken for these LOS versions?

Thanks in advance!
[Shield Tablet Original Android Development] Steel01:
I still mess with the tablet from time to time. Another Lineage dev took a shot at getting 17.1 to boot, but with no more success than I had. 16.0 is mostly usable, but not completely stable. Nvmm (which provides hw audio/video acceleration) does work on 16.0, there have been unofficial builds of that for a while now.

As for twrp, the actually topic here... Twrp does not compile in Lineage 17.1 as of right now. So I can't update the tablet (or any other device I support) to the android-10.0 branch. The android-9.0 builds from a Lineage 16.0 tree work very well, though. Once some stuff settles on the Lineage gerrit, I'll be looking to push updated official builds. No guarantees on the timeline for that, though.
[Shield Tablet Original Android Development] nuovagrafica:
hello I need an old zipped version of TWRP for Nvidia Shield Tablet K1 because I'm not be able to flash img files
[Shield Tablet Original Android Development] nuovagrafica:
ok let's see if I can explain my issue in another way...

some time ago I had android 5.2 with TWRP and root permissions

now I'm on Android 7 and I'm not able to install TWRP and root permissions anymore

if I go in fastboot in my nvidia shield tablet K1 I have the first picture .

if from fastboot I go in recovery mode I have the second picture. the green robot.

if from the green robot I press volume up and power button I have the third image Android Recovey

does the green robot means TWRP is missed?

now if I try to flash twrp.img (4th picture) it says waiting for device and the tablet reboots in Android OS but TWRP is always missed

I'm sure if you can send me an old TWRP version in zip format I can solve or if you are able to convert TWRP.img into TWRP.zip

what do you suggest?

Can I at least have root permissions what file must I to install? can you provide me the correct link please?
[Shield Tablet Original Android Development] jamescable:
Update your fast boot drivers. Right now you have stock recovery

Well I never got a recovery log from [MENTION=6169180]philipp21897[/MENTION]

I am sure it works, there is a setting that users get to choose when TWRP boot...

That will not let TWRP set system read/write, it leaves it read/only for backup and OTA purposes....

So take this for face value, without a recovery log there is no confirmed issue.....

Thx Josh
[Shield Tablet Original Android Development] afilbit:
Sorry didn't know that because I didn't had the tablet maybe he chosen the read/only option... I would try and give you a log if something happened if I had the tablet. The guy said that the k1 and the older shield tablet are the same and everything has backwards compatibility so I don't know... Just tried to help

[Shield Tablet Original Android Development] DreadApex:
I seem to have run into a pretty large bug.

I updated to the new 2.8.7.3 TWRP from 2.8.7.1.

I then proceeded to do a complete wipe and reinstall on my Shield LTE (US) Tablet.

TWRP was unable to wipe the system partition, it would stall on format. after a long time, I finally restarted and tried again...same thing.

I then tried to repair and it was unable to mount system and unable to repair.

I then tried swapping the system partition to ext2 which worked and i finally had a system partition again.

after trying to go back to ext4...same stall, it just couldn't do an ext4 format.

I then tried reflashing the latest twrp again just in case, I got all the same results.

Finally, I flashed 2.8.7.1 again and tried once more. it formatted with no problem and was able to swap in and out and manipulate ext4 partitions as expected once again.

Apparently there is something wrong with 2.8.7.3 and the ability to manipulate ext4 partitions, or perhaps just the system partition...?
[Shield Tablet Original Android Development] lj50036:
Well I would need recovery logs to be any help in fixing this issue..

Did you leave /system read/only ?

That would cause issues for sure ....

So without any recovery logs not much I can do as its working for me perfectly .....

Thx Josh
[Shield Tablet Original Android Development] DreadApex:
Unfortunately, the logs are wiped and i have since gotten a working install again and am wary to go back to reproduce.

If it is working for you then perhaps it was just an isolated incident.

All I know is my tablet didn't seem to get along with the latest version, reverting fixed the issue instantly.

I was able to format into ext2, just not ext4. I tried 4-5 times and flashed the new img twice before reverting.

I just wanted to say something in case it was easily reproducible.
[Shield Tablet Original Android Development] afilbit:
Finally puted my hand on my Nvidia Shield Tablet K1. I had problems with 2.8.7.3 and 2.8.7.1. I couldn't make backups or flash roms. TWRP couldn't mount /system and had problems with something binary (I know nothing helpful). But had no problems with 2.8.7.0... Just so you know

[Shield Tablet Original Android Development] hochoch:
I would like to assist. I'm currently stuck, how can i pull logs for you? Using a brand new K1.

thanks for you efforts!!!
[Shield Tablet Original Android Development] Exile1975:
Just to put my two cents in, I've got a k1 with twrp installed. I haven't tried to format the system but I have used the format option for the cache. The cache is much smaller than the system partition and it takes a LONG time to complete. I would assume the system partition would take longer to format. So to those having problems my question is, are you sure your waiting long enough? Cache takes more than five, and less than ten minutes for mine.
[Shield Tablet Original Android Development] lj50036:
Post #30 :)

That is odd it does not take mine that long to format any partition....

Let me have a look into this .... :good:

Thx Josh
[Shield Tablet Original Android Development] hochoch:
Cool, will give it a shot tomorrow.
[Shield Tablet Original Android Development] hochoch:
Ok - so i installed twrp 2.8.7.3 and it would not boot into recovery, just the dead android with the red exclamation. i was able to boot into 2.8.7.0, but when i try to pull logs while in twrp it says no devices. when i reboot the tablet it says that the log/directory does not exist......

not sure what else to try from here. do i need super user installed?
[Shield Tablet Original Android Development] DreadApex:
I waited about 20 min before giving up on my format. Fornatting to ext2 took about 1 second. Formatting to ext4 once i reverted took maybe 2 seconds...
[Shield Tablet Original Android Development] Exile1975:
OK so I actually timed the format. Cache format took me 2 minutes and 53 seconds, wiping dalvik was instant. I also pulled a log but I can't figure heads or tails with it, to me it looks fine.

Unfortunately a fastboot boot twrp- of the 2.8.7.3 fails for me with marshmallow. (2.8.7.0 too)

Any logs or anything we can provide to help you?

Not at this point is a bit early for logs, let me get up and running, and we have a look.... :D

Thx for all the support.... :good:

Thx Josh
[Shield Tablet Original Android Development] An Droid:
Perhaps I'm wrong, but I don't understand how recovery could be impacted by the Android OS version - the two are separate and independent of each other AFAIK. Recovery doesn't 'run' under Android.

If recovery references or was built for an incorrect/different hardware model, then I can understand issues arising - perhaps this is what you're seeing? Original Shield vs. K1 branded version?

Please correct/enlighten me if I'm wrong! :) :confused:

I can confirm, cannot boot current TWRP on Marshmallow.
[Shield Tablet Original Android Development] Smultie:
So, no root for as long as we don't have TWRP for the Shield Marshmallow, right?
[Shield Tablet Original Android Development] philipp21897:

[Shield Tablet Original Android Development] ruoani:
For root, you just need to flash a modified boot.img from this thread and install the app. Works fine.

[Shield Tablet Original Android Development] Smultie:
Nice! Worked here too! Any specific reason why SuperSU doesn't work?
[Shield Tablet Original Android Development] drewski_1:
There may be a new Bootloader with the 6.0 upgrade. Maybe this is causing issues with the current TWRP?
[Shield Tablet Original Android Development] krbvroc1:
I believe it is because of changes with Marshmallow using SELinux. The previous SuperSU is not compatible/aware of that. I recall seeing a beta version that will work with Marshmallow, but I am not sure it is out of beta yet.
[Shield Tablet Original Android Development] JazzieBoi:
So when I updated my K1 to 6.0 I lost root and twrp won't work any more. So I have been looking on the forums for answers. Where is the boot.img you are talking about, because the thread you linked there is no boot.img on that page, but I did find this: http://xdaforums.com/android/software-hacking/wip-selinux-capable-superuser-t3216394 is that it? And to flash it its just fastboot flash boot boot.img right?

This is the boot image you're looking for, and its on page 11, 12, 16, and 19 in the thread he linked. Just a little bit of reading....

[Shield Tablet Original Android Development] zarish:
For me that version seems to change the display every other touch/click. Not really that it was laggy but that only every other action would actually update the display.

Example: I'd click advanced to try and get to file browser, it won't change, but then if I clicked right where restore is still displayed (which is File Browser on the 'Advanced' screen) then I would immediately dump into File Browser (even though it looked like the system was still on the main screen). Once I learned that I found the responsiveness wasn't actually lagging, just something odd with the way it updates the display.
[Shield Tablet Original Android Development] zarish:
Ok, so I tried the 3.0.0-0 image that showed up here: https://dl.twrp.me/shieldtablet/

Initial results:

On the Android 4.4.2 tablets, the Recovery boots, but the display is shifted 1/3 of the screen to the right and then the right side wraps onto the left side of the screen. NOTE: The actual touch detection is in the positions that would be correct if the GUI were displaying correctly.

On the Android 6.0 tablet, the system sits at the NVIDIA logo for a few minutes and then reboots to the OS on any attempt to enter Recovery.
[Shield Tablet Original Android Development] lj50036:
Yes, this is only for the L bootloader...

As the release said that there could be issues, is true... :D

I am looking into this, but this release is still only going to work on the L bootloader...

M is going to have to wait for now :)

Thx Josh
[Shield Tablet Original Android Development] zarish:
NP, Just gave it a go since it was up.

Figured it would give a results report as well as answer the inevitable questions about if it was working on M or not. Honestly didn't expect it to work for M as I figured that would most likely be a new/separate image.

Thanks again.
[Shield Tablet Original Android Development] Dashwood Foxe:
Funny that you said this TWRP version doesn't work on MM yet all over XDA, version 3.0 was advertised to work on MM, with adoptable storage support!

It doesn't, flashed it yesterday ,its available on twrp.me, but it wont be able to boot in recovery if you are using the OG ST, had to switch back to 2.x.x.x the experimental one for MM roms
