Abnormal screen rotation whilst connected to a TV is so disorientating on this ROM. For no good reason I'll get stuck in portrait (which is rotated 90 degrees) for landscape TV compatible apps - despite Settings > Display > Rotation being set appropriately. I would have to restart the device to resolve the problem. I've seen it throw TWRP touch cordinates off to afterwards.

Another weird issue I encountered was... Although I could get my OTG usb flash drive to mount - it's not visible in apps that can use it.

VLC for one just wouldn't show my OTG stick. The flash storage device is mounted, can be seen seperately in the 'file explorer' (not VLC) app, that then allows me to traverse through files; but for some reason I still cannot 'open with' VLC as a workaround.

The wireless 360 controller kept losing connection with the receiver, it was a party on the controller player/power LED indicator. Revert to Nvidia Official 5.4 firmware and VLC with OTG flash drive, rotation, and my 360 wireless receiver is happy again. Very odd.

Also, I'm curious. Has anyone found a good substitute for joystick to mouse functionality with a gamepad? Like on official? Some stuff just needs clicking... The search bar in the Play store is a good example.

Performance otherwise is pretty great on this ROM though, so I'm pretty eager to get these quirks ironed out. That, and I don't have to deal with Nvidia Games restarting every 10 minutes (exaggeration - although it's a lot) or so.

Updater process ended with Error: 7

Hello,

I am trying to give my tablet a new life so i tried changing its ROM with this one. But when I try to sideload it with TWRP I have the following error : " Updater process ended with Error: 7". I don't have any error when doing the same with the Google apps.

I have followed the tutorial here : https://wiki.lineageos.org/devices/shieldtablet/install

I tried to solve the issue with this tutorial but it doesn't work either : https://xdaforums.com/showthread.php?t=2522762

My tablet is an original Nvidia Shield tablet.

If anyone if anyone can help me, that would be great.

Thanks for your work

You need to flash the firmware 5, then let the tablet boot then restart to recovery and should works. you can find it here: https://xdaforums.com/shield-tablet/development/rom-lineageos-shield-tablet-t3562839

Hello, and thank you for your continued efforts on this really old (but not bad) tablet. I have the original LTE 32GB model and I just unlocked my bootloader, flashed 3.1.1 TWRP recovery, wiped everything (except MicroSD Card) and flashed this ROM, rebooted to recovery, flashed latest 32-bit (7.1) GApps Nano, rebooted to recovery, flashed latest Magisk, rebooted into system. Everything looks good but I have two issues I was hoping to get assistance with.

1. When I get into the ROM setup, it eventually gets to the setting up Google Assistant and failed to download the voice model. I can hit retry as much as I like, but it still fails. I can also hit dismiss, and it will go on, but "OK Google" feature does not work and I get regular errors about it trying to download the latest voice model file and failing to do so. I have researched and tried a number of 'fixes' but I have been unsuccessful in resolving that issue.

2. When I launch the Nvidia Games app, it gets stuck on the downloading information screen at the beginning and never shows the list of games. I can't log into my account or anything else either.
[Shield Tablet Android Development] windyhawk:
Thanks for the note. I think i will flash 14.1 for now until 15.1 is proved to be better.

The security updates for August are here.

LineageOS 14.1 August 2020

LineageOS 15.1 August 2020

just security fixes, as always.
[Shield Tablet Android Development] TheToxicant:
Thank you again The-Saint2k for all the work you have done. That said this update you released made the tablet almost feel OEM like in terms of operations and I personally think this is the smoothest running update yet.
[Shield Tablet Android Development] player594:
Is there a way to have the lock screen be in landscape mode? I never use portrait.
[Shield Tablet Android Development] ogremalfeitor:
Yes, by editing build.prop and adding:

log.tag.launcher_force_rotate=VERBOSE

lockscreen.rot_override=true

That way it should respect your rotation preference on the lock screen.

You need root and an app that eases the process (I flashed Magisk for root and used smart pack kernel manager, but you have many options available for that). Reboot afterwards.

Never understood why LOS dev team never bothered to include these options.

This could however be included in the build... What do you say The-Saint2k?
[Shield Tablet Android Development] Technojo:
Thanks! Should we just flash this over the ROM?
[Shield Tablet Android Development] airtower:

What's the trick in getting decent deep sleep battery life with this ROM?

I have tried AEX but the frequency of random reboots made me wipe & try this 14.1 but I was shocked that a 100% battery (only half real capacity) would drop overnight to 10-15% with the screen off.

AEX 5.8 was a real eye-opener for deep sleep battery life, overnight it might drop 8%.

I tried the latest 14.1 with the BitObsession kernel but couldn't figure out how to stretch out the battery. Before AEX I had another LOS 14.1 ROM but the performance was not great and no further development.
[Shield Tablet Android Development] Kvaks:
Trying to upgrade from an old Cyanogenmod 12 to Lineage 14.1 on this device.

How do I get passed the error "This package supports bootloader(s): 4.00.2016.06-8b2413b7; this device has bootloader unknown" ?

I've done the following to try to get passed it: Flashed the latest stock ROM (which I thought would bring with it new bootloader). Flashed the newest supported TWRP. Still the same error. How do I find a new bootloader and update it?

Thanks in advance!

Solved! This here post. My mistake was to try to update the bootloader by installing the zip from within recovery mode. Instead I should have unpacked the "blob" file from the zip and flashed it in fastmode. When I did that, rebooted, reflashed TWRP and tried again to install LOS14.1 from TWRP, it worked this time! Nice!

Hello. Nice ROM, THX

For fix bug Netflix, i've solved my PB in dev mod: just switch on option "Force MSAA 4x" and option "use allways GPU"

Now Netflix Work for me .

Bye
[Shield Tablet Android Development] Scavenger87:
Hi you mean you fixed the HW Acceleration Bug on the 15.1 Build with this ?
[Shield Tablet Android Development] roan67:
No, i'am not dev. Just switch two options because netflix have a green screen and cubic.

Yes i use this ROM 15.1

Non, je n'ai fait qu'activer deux options dans les paramètres développeur. Maintenant je n'ai plus l'écran vert saccadé sur netflix. Cette ROM me permet de faire tourner mes applications préférées. Root, Adaway, netflix, prime vidéo vpn, iptv et tous les sites de replay. Par contre cela consomme Beaucoup de batterie, mais au moins je réutilise ma tablette shield.

I saw recently a file named lineage-14.1-20201006-UNOFFICIAL-shieldtablet.zip is this a new update or a re-upload ?

And Thank You in any case for the hard work to keep this Rom alive :)
[Shield Tablet Android Development] The-Saint2k:
Yes completely correct it is the newest build. 15.1 I will still upload today, unfortunately very late.

LineageOS 14.1 September
[Shield Tablet Android Development] Scavenger87:
Hi

Thank you for keeping us updated on that i will test it out soon on one of my tablets :)
[Shield Tablet Android Development] The-Saint2k:
As already announced, now the Build 15.1

LineageOS 15.1 September
[Shield Tablet Android Development] ogremalfeitor:
Many thanks for your great work.

Updated mine to the latest 14.1 build.

Anyone is having issues with deep sleep mode? Mine discharges about 20% overnight (unless I turn it completely off), but the battery itself looks good because it lasts 4 hours or more watching movies.

Any advice?
[Shield Tablet Android Development] Scavenger87:
I installing the new September Rom to the OG 16GB Tablet right now the first issue i had was that my Full Gapps refused to install in TWRP with the Error 70.

I also tried the fix it with wiping, resize and repair the system partition but with no luck. But its maybe because of the age of the zip its from august if i remember right and i also was about to change to the pico pack anyway which worked like a charm :)

About the idle battery drain i can test the old and new rom side by side now but how you measure it on your device ?

I mean with wifi off or on ?

Because i think its not really meaningful with wifi on because the playstore does updates on idle and apps loading things also then
[Shield Tablet Android Development] ogremalfeitor:
I had the option to always keep WiFi on. Maybe that's it, many thanks. Changed to only when plugged in and will check how it goes. Thanks again.
[Shield Tablet Android Development] Scavenger87:
Ok did a test on the both last versions of this build with the wifi settings also on "only when plugged in.

LineageOS 14.1 August

From 22:23 -> 07:23 - 7%

From 07:23 -> 17:45 - 12%

LineageOS 14.1 September

From 22:23 -> 07:23 - 0%

From 07:23 -> 17:45 - 1%

In both cases i started first the PlayStore on both Tablets to do pending updates first.

But this was only a first test thats not very accurate because "August" has a lot more App installed and Accu Battery that also eats a bit battery.

"September" has just been set up with Gapps Pico and some Apps.

But i will do this test again when i reinstall "August" again also with Gapps Pico.
[Shield Tablet Android Development] ogremalfeitor:
Since yesterday, with keep wifi set as "only when plugged in", I lost 1% or something like that. At least for me it solved the issue. Thanks.
[Shield Tablet Android Development] Scavenger87:
I also did another more accurate test again now with both tablets freshly installed Roms + Pico Gapps + same Apps over 12 hours and the results now is total equal:

LOS 14.1 August

07:34 -> 19:39 -4%

LOS 14.1 September

07:34 -> 19:38 -4%

Thats means for me at least it has much to do which settings are set like the wifi auto turn off on deep sleep and which apps are installed and running in the background.

But the option keep Wifi on "only when plugged in" brings in any case a improvement even on the Tablets with the OEM Rom i have.

The new ROM runs smooth as usual and i didnt found new issues so far. Of course i also tried my luck on the Nvidia Games App from the Playstore again like on every update either on the app or rom but it still doesnt let me login or does load the Gameslist.

This Rom would be a real alternative for me to the really slow OEM Rom if at least Nvidia Games App would work again.

Before i reinstalled "August" i tinkered around in the Root folders of this and the OEM Rom and added the missing files,apks,permission,... to this Rom and i was at least able to start the login sequence which worked fine but it still wasn't able to load the Gameslist.

I also got a lot of errors from the gamecast and controller app even when i did a factory reset on the LOS Rom.

I know its not the way to do it just adding missing files to a different Rom because i absolute sure there is much stuff that have to be rewritten right but its my way to find out how this Roms works :)

Did you install 15.1 or 14.1?
[Shield Tablet Android Development] Snah001:
Is LineageOS 14.1 from October 2020 the last build or did I miss a build after that?
[Shield Tablet Android Development] The-Saint2k:
Yes, this is correct. Currently I have the problem that my build environments no longer run. I have already rebuilt the environment for 15.1 and therefore already uploaded a current build in January. Currently I do not plan to do the work to rebuild 14.1 again. I am currently using 15.1 and have no problems. It runs Prime Video, Disney+ and Netflix. Can others confirm this? Wouldn't it make sense to bury 14.1 then?

January Build 15.1
[Shield Tablet Android Development] ogremalfeitor:
Hi.

Unless I'm missing something, the 15.1 build has no video hardware acceleration right? I just flashed it and YouTube videos of 1080p 60fps are very choppy... making it unusable for me.

Or did I miss any step while installing? Is there any trick to enable acceleration?
[Shield Tablet Android Development] The-Saint2k:
hi,

You are right. I was aware that the problem with hardware decoding is not solved. since I do not have GAPPS installed, I do not pay attention to something like Youtube. I just noticed that Netflix currently has no problems with me. Currently, we also use the tablet only for children's audio books, because the display glass is cracked.😭

I have now sat down yesterday evening and created a new environment for 14.1. I have uploaded a build. It would be nice if someone would install it and report whether it works, since my Cert Keys are now also new, since the old ones are gone. There should be no problem though.

[Shield Tablet Android Development] ogremalfeitor:
Hi.

Meanwhile I was back on 14.1, had a lot of trouble restoring my data and apps... now when I try to install new build it throws the error in TWRP: "can't install this package on top of incompatible data"

Do I have to wipe my data once again? :(
[Shield Tablet Android Development] zagzag99:
@The-Saint2k thanks for a new 14.1 build but I guess something changed in how it expects data partition would be.

I'll wait to hear if someone else managed to install before I try a full wipe.
[Shield Tablet Android Development] ogremalfeitor:
My guess (correct me if I'm wrong) is that LOS installer embedded in the ZIP file checks the data partition comparing the user keys, and if they don't correspond to the image user keys then it refuses to install. And the keys have changed, as @The-Saint2k said, since he no longer has the old build environment.

I ended up wiping and installing fresh. Working normally so far.
[Shield Tablet Android Development] Snah001:
Yes, same for the 15.1 build.

Had to do a clean install, no problem with that because I use the tablet only for reading and browsing in bed.

I did a clean install and it works very good, thank you!

You may need to check your TWRP version. It helped me by going back to an older version of the recovery.
[Shield Tablet Android Development] Deni1986:
Hey, first of all, thank you so much for all the work you spent in this project, it helps alot of people like me using their older devices way longer than the original developers intended (;

I recently fetched my shield tab and saw, that there is still development in the software so i decided to try out los15.1 or even 16. i spent a couple of hours to inform myself concerning twpr, adb, fastbook and the tool i need for flashing, but all the tutorials lack of information of possible combinations of the bootloader (i guess its the blob.img file) and the twpr. to flash 15.1 i need a later vesion of twpr installed than the one ii found working with my bootloader (bootloader is 4.00.2016.04 with twrp3.0.2.1). I tried looking for a more up to date blob.img but acutaly could not find one. can you please give me a hint, where to download and how to check, which bootloader version is compatible with which android version?

Greetings from germany
[Shield Tablet Android Development] Entodoays:
https://dl.twrp.me/shieldtablet/ Get the latest, since your bootloader is more recent than 3.1.1
[Shield Tablet Android Development] Deni1986:
Just followed these instructions to update the device to android m, now the latest twpr version is running but the bootloader version tells me: undef_build.

i flashed the blob.img i used before, but still this number is mentioned (with a working current twpr). isn't the blob the bootloader image? if i try to install los 15.1, it erros that it needs a bootloader version 4.00.2016.04, which is actually the one that i used before but that was not able to run a higher twpr version than 3.0.2.1, which was not able to flash the los 15.1 image.
[Shield Tablet Android Development] Deni1986:
thanks, i did, but the device would not start the recovery with a version later than 3.0.2.1
[Shield Tablet Android Development] Entodoays:
I never flashed any blobs. I went from Stock N to official LOS 14.1. Then I updated TWRP a few times and now it's running the latest TWRP and unofficial LOS 14.1. I had tried 15.1, but at the time it was buggy. Now I no longer have the device, but it is being used by someone else.
[Shield Tablet Android Development] Deni1986:
I actually cant update to 15.1 due to twpr is currently not working with higher version than 3.0.2.1...

I just recignised, that the actually flashing process of the bootloader is not taking place while using the fastboot commant. the version number of my bootloader changes, after i shutdown the tablet afer the fastboot command, and let the device perform a regular boot (which will not happen due to there is currently no os installed). if the device is connected to a pc, it indicates the finish of the process by the "new usb device connected sound" of the pc.

edit: but these are only guesses right now (;

edit 2: okay, the same for me for the recovery! after the first reboot after flashing the recvery, i was not able to get into recivery mode so i just waited, device connected to the pc, until the "new usb device sound" appears. then shutdown (with keys), then reboot into bootloader, then i was able to get into recovery (;

now im on latest twpr with 4.00.2016.04 bootloader

edit 3: awesome, flashing 15.1 now (: Hope this might help others (;

Hi all,

Sorry for the silly question: I have a Shield Tablet with "lineage-14.1-20201101-UNOFFICIAL-shieldtablet" and I tried today to update with TWRP (version 3.4.0.0) to "lineage-14.1-20210312-UNOFFICIAL-shieldtablet" but i received following error:

"Can't install this package on top of incompatible data.

Please try another package or run a factory reset.

updater process ended with ERROR: 7"

I upgraded TWRP to version 3.5.1_9-0 and retried to install same image ("lineage-14.1-20210312-UNOFFICIAL-shieldtablet") and now and received:

"E3004: This package is for device: Shieltablet; this device is: .

updater process ended with ERROR: 7"

I would like to avoid a factory reset or a complete reinstallation if I could.

Any idea?

Thanks

I just flashed this rom (14.1) over AEX a few nights ago because AEX was getting more and more unstable almost by the hour.

From what little I've been able to test so far, this rom works great, except for one problem. Battery drain.

I can barely keep the tablet charged above 4% even while plugged in. Using the same standard 5v USB wall charger that I've used for years.

One thing I noticed, when looking at battery information, cellular location data is in the red. But even after flipping to airplane mode and switching off all location gathering, it's still draining almost as fast as it's charging.

Is this a known issue? Is there some setting that I'm not seeing?
[Shield Tablet Android Development] Entodoays:
Did you dirty or clean flashed the ROM?
[Shield Tablet Android Development] mkhopper:
Full factory wipe.

Easy enough to do another flash if needed (if I can keep it charged long enough to boot into recovery), but I was hoping there was a setting somewhere, maybe in dev options, that I just haven't found yet.

Hello together,

Unfortunately I have to announce that I will stop creating the builds. Since the tablet has not been used for some time due to a severe display damage, I have already stopped using the last builds myself.

Anyone can create their own using the Docker image from MicroG. MicroG does not have to be integrated either.
