[Shield Tablet Android Development] Inganno:
Tested lastest release too, it seems a little bit more stable in terms of applications loading/multitasking but it still feels like the memory is not optimized; it still happens that having 2-3 apps in background (light stuff like f-droid or settings app) and launching a new one, i have to launch it 2-3 times because it crashes, like memory is full (even if from dev options i can see RAM is around 1GB over 2GB available).

By the way, im not sure this is a ROM issue or what because im running LOS + Magisk + MicroG (+ signature spoofing patch) + Shelter, so the setup itself could generate some issues too that could be unrelated to ROM.

Also noticed that video playback is broken on Instagram; its quite stuttering and full of green artifacts; previously i was running 20210205 from here and this issue was not present. (PS: just tried and NewPipe playback seems suffering from those green artifacts too, no matter the resolution of the video).

Another issue I noticed is that power settings (power off and reboot) are occasionally buggy; it happens from time to time that running "adb reboot bootloader" from linux or simple reboot into recovery/bootloader/system from device-menu got the tablet semi-stuck, having to wait like 2-3 mins before it actually reboot-turn off. On this last version sometimes the screen at boot or wake is total black, leading to a manual reboot.
[Shield Tablet Android Development] Jsoares82:
I tried call of duty mobile and it seems to stutter a bit whilst loading (graphics and sound) and then goes super smooth. I think the kernel may not be optimised for performance? Seems to be slow switching cpu states when going from idle to load? Could be to improve battery performance but not ideal for gaming. I may be talking rubbish but that's really what it feels like. Would be great to have some switchable profiles for battery / performance. Also, I have done a clean install of latest release and am only running gapps pico in addition to the rom if it helps.

Multitasking is pretty much broken imo. Can't really switch from a fullscreen app to another without one or both crashing.

Would it help trying a new kernel?
[Shield Tablet Android Development] airtower:
Similar observation here. I ran a resource heavy application (Garmin Pilot) for 15-20 minutes yesterday and it was near perfect. However switching between other apps was problematic. I did not try youtube or any other video playback.
[Shield Tablet Android Development] Morsure:
Hello, thanks for your work,

From my side, i'm coming from the 5.4.1 rom.

I'm on the TWRP 3.2.3-0. and i tried to install the Lineage 16.0.

Unfortunately it stays on the lineage bootscreen, and after that it boots directly to the TWRP recovery... I don't know what to do...

I don't update the shieldtablet-firmware-50-update.zip

I don't know how to do it... Thanks for your help
[Shield Tablet Android Development] Jsoares82:
I didn't update the firmware either. And it's "working".

I might try updating the firmware and see if it helps sort out some of the issues I have.
[Shield Tablet Android Development] Morsure:
Hello,

It's OK now, i did a factory reset from the OS,

And after that flash it again and wipe 2 times.

Thanks Jsoares82!
[Shield Tablet Android Development] Mikesraxx:
Use latest twrp zip what worked for me was

For an clean Installation its important to wipe the device first with TWRP

After this go to Advanced and choose everything wipe davlik,data,cache,internal storage

Now you shutdown the Tablet

Boot into bootloader manually

After turning on the Tablet and choose Recovery Mode again, first install the Rom of course then choose Wipe cache/dalvik.

Now you have to install Gapps if you want to use it. Its recommend to use only the Pico Package.

Wipe cache/dalvik again and restart the device.
[Shield Tablet Android Development] Mikesraxx:
Use latest twrp zip what worke
[Shield Tablet Android Development] aliak47:
Thanks for making this software. I have installed it according to the instructions and it is working somehow. I have a couple of issues. I cant seam to get SU to install using the zip. Im using addonsu-16.0-arm-signed.zip with the latest twrp. Nvidia apps is not working. And the last issue i have is "shield tablet setup in progress" crashes or never finishes no matter what i do in the app. it keeps coming up until i choose "remind me later" and then of course comes back after a while.
[Shield Tablet Android Development] muellerm30:
Great ROM and I seem to have gotten most things working. Using props, libeoencryp, magiskhide I'm able to get Disney, Netflix, etc working.

The one stupid issue I'm having is I'm not able to pair a PS4 Dual Shock controller. I know its pretty minor. I've clean reflashed everything but it just wont pair. Any ideas?
[Shield Tablet Android Development] AWDGuy:
Working, but thought I would share my conversion experience...

First, Thank you so much john_matrix for all the work, and Scavenger87 for his Notes, and tips...

Came from 5.3 Official on Original Non-K WIFI only... unlocked BL and tried TWRP 3.5, no go.

Read TWRP page and tried 3.1.1.1 and got the not compatible error.... finally tried twrp-3.2.3-0-shieldtablet.img

Should 3.5 work??

Can't reiterate what Scavenger87 said enough.... WIPE!!! (Ask me how I know...) third or 4th try....

Wiped all before, + dalvik/cache after each sideload. 20210208 + open_gapps-arm-9.0-pico-20210311

Booted, but as if digitizer sensor is whacko, and screen flickers. Manged to get "start" to work once, but then can't do anything on wifi page.

Tried Vision settings next boot for kicks. Eventually started to load page, but blank and hung.

Third reboot is a charm? Slow at first, but WIFI finally responded, signed on and syncing.

I am assuming TegraOTA is a non-issue on Lineage??? (Recalled tablet I resurrected from a drawer...) When I looked in FM from TWRP before updating on stock 5.3, only thing in \System was a lib folder... Is that Weird?

Thank you again!
[Shield Tablet Android Development] Avalon72:
I had some time to test the latest Lineage 16.0 of Feb 8th on my Nvidia Table K1 Wifi only (P1761W).

I have TWRP 3.5.0.9.0 and after the usual wiping process I could sideload the new ROM as well as latest OpenGapps 9.0 pico of March 11th.

YouTube, and various video providers apps are working well on first attempt after a cold boot. Then if for instance I move to another video on YouTube, I have the former issues with this greenish video (seems like a codec issue as there are "blocks" rendered on the screen). And then the problem stays for all other subsequent attempts.

Audio seems ok generally, but I noticed some gliches at the beginning of some sounds. Not always.

Wifi (2.4 GHz band) is ok. Didn't notice particular issues.

The power consumption is also ok.

NIvida Games (updated on first launch of Aurora Store) is working for the first time on my tablet. That's great !

I can quickly switch between apps. Didn't notice any particular issues or slowdown after first launch.

I paired some BT headphones for trials with videos. Worked but then at second boot:

- screen was black, and the headphone indicated that they were paired. But no display on screen. So something was running in background.

- I had to make a hard reboot (long press on power on button). Then the boot was normal, but showing a depleted status for the battery (which isn't true). After a minute or so the battery was showing a normal status. I'm wondering if both issues are linked. I just hope my battery is not starting to have HW flaws. But up to now I never experienced such issue.

Most applications are running well until now.

All in all, I'd say that this release is better then the previous one. Apart the video issues, it's really cool.

Thank you @john_matrix for your work.

PS: If one day you would have time to post the steps you do for building a ROM image for this tablet I'd be interested and grateful.
[Shield Tablet Android Development] CesarOrtiz:
Hello ... I installed everything, the Rom, the Gapps and the SU but the firmware update did not.

I threw an error (number 7).

Does anyone have the support of the k1 shield (wifi version), kindly share it with me to download it and install it?

Thank you
[Shield Tablet Android Development] Mikesraxx:
Do you mean stock version?
[Shield Tablet Android Development] CesarOrtiz:
Yes, I mean I want to reinstall the stock version (original factory rom)

Hello,

As npjohnson's builds has now update menu working, I don't know if this is useful to continue to compile builds here.

I keep the Ubuntu WSL image and if someone wants to have a new build, let me know and I will compile it otherwise there will no longer be regular updates.
[Shield Tablet Android Development] ogremalfeitor:
Hi.

Sorry if I'm a bit lost, but I can't find those builds. Can you point me to the thread? Or is it not something on XDA?

Are these the npjohnson's builds?
[Shield Tablet Android Development] moviefirst:
Ignore!
[Shield Tablet Android Development] ogremalfeitor:
Tried it (clean flash), unfortunately I get constant crashing on almost anything after a while and gets unusable (I even got a full "black screen of death" once, forcing me to hard shutdown by holding the power button for several seconds). Happens with every ROM greater than android 7.1 with my tablet, I was hoping this would be different :(

Which is a shame because it works very well (when not crashing) with apps like YouTube Vanced even at 1080p 60fps with practically no frame drops... (unlike some others I've tried greater than 7.1 which either have unbearable frame drops or play completely distorted and without color).

I know that using stock or lineage os 14.1 ROMs is stable, in fact I've been using a LOS 14.1 build from another thread that is fast and works (but it feels so outdated that hurts)... So is there any trick to make this LOS 16 build stop with the crashes? Or anything (such as logs) I can collect and send to help solving it?

Or should I definetly give up on having anything better than android 7.1 on this tablet?
[Shield Tablet Android Development] brianx87:
Is this ROM for Shield or Shield K1?
[Shield Tablet Android Development] Mikesraxx:
Both I have a shield k1 and tried this rom
[Shield Tablet Android Development] brianx87:
Is there anything I need to know before flashing this ROM, does everything work out of the box or are there issues, all the nvidia software pre-installed and working and such?
[Shield Tablet Android Development] Mikesraxx:
No there are some bugs YouTube screen flickers green some apps don’t open at times Vulkcan doesn’t work I use lineage 5.1 is more stable

Thanks John!
[Shield Tablet Android Development] ogremalfeitor:
Are the hardware video acceleration issues on YouTube solved on this one?

Also, do you have many apps crashing on it?
[Shield Tablet Android Development] Scavenger87:
From what i saw they improved it very much so far at least with the youtube app i didnt had any issues so far.

Its also nice to see how this Rom improves in stabilty and speed on every release a big thanks for the work and effort to @Steel01 and @npjohnson and all the other devs that working right now on this Rom :)

And i know its a lot of work because i learn at the moment how to build my own Rom for this device which is based on LineageOS 15.1 for the reason its easier to learn because of the structure of the propetiary folders. But when i imagine how much knowledge is needed to write the code i just playing around at the moment and when we take in account there is none official release for the K1 Chip (T124) above Nougat its even more impressive.

Please keep up the good work ;)
[Shield Tablet Android Development] jaeskeels14:
hi i just try this ROM buy im stock on LINEAGESOS logo,.

and restart again and stock
[Shield Tablet Android Development] Scavenger87:
If you did all the steps i mentioned earlier in this Thread and it still does stuck on the LineageOS Logo you should redownload the Rom from Npjohnson's Site

Here again the Steps to do a clean installation :

Maybe a little general guide for everyone here who want to try this build in this early state and help tracking bugs :)

For an clean Installation its important to wipe the device first with TWRP like shown on the first Screenshot.

After this go to Advanced and choose everything choosen on the second Screenshot.

Now you shutdown the Tablet and insert the SD Card or plug in the cable for sideloading.

After turning on the Tablet and choose Recovery Mode again, first install the Rom of course then choose Wipe cache/dalvik.

Now you have to install Gapps if you want to use it. Its recommend to use only the Pico Package.

Wipe cache/dalvik again and restart the device.
[Shield Tablet Android Development] jaeskeels14:
ahh okay isee tnx.

is shield accessories working here so i can still use my orginal nvidia shield controller? tnx
[Shield Tablet Android Development] ogremalfeitor:
Well, tried the new release (clean flash), but it's just like any of the others above Nougat... YouTube videos work sometimes, other times they just show some greenish thing. Settings app crashes 100% of the times I try to use its search. As for stability, it's still not usable on my device because every 5 to 10 minutes there is an app crashing (frequently it's the home launcher), browser just shows black bars randomly, apps won't install and so on, until the device ends up rebooting itself or simply hangs :(

(In LOS 14.1 I get no crashes or video corruption so it's not hardware fault, but every ROM above Nougat misbehaves badly on my device and this one is no exception)

I gave up on this device some time ago so I'm gonna put it back in a drawer (you won Nvidia... I will never buy tegra devices again), however thanks anyway to everyone still trying to make something of it.
[Shield Tablet Android Development] airtower:
The April build is great! Governor seemed to stick on max after first boot (device got very hot, would not maintain 100% batter on a charger), but fine after reboot. Quick youtube test worked fine.

I could not playback YouTube TV, presumably due to DRM. liboemcrypto module in magisk cleaned that right up.
[Shield Tablet Android Development] Mikesraxx:
Wondering how’s the battery life???
[Shield Tablet Android Development] airtower:
Can't really comment, it hasn't left my desk on the charger
[Shield Tablet Android Development] Shadoe_Lance:
The latest of npjohnson's builds shows I have no SIM card installed on my LTE Shield tablet. Anyone else have this problem or solution?
[Shield Tablet Android Development] Trailmix&Keyboards:
Hi, just wanted to throw my hat in the ring with regards to the 16.0 builds. It works pretty well. A few apps will spontaneously fail to load, but a quick restart has fixed everything so far. The stylus also still works, which is the main reason I wanted to revive this tablet. There were some weird green youtube issues early on, but I haven't seen them since the first restart. All it needs now is a battery replacement and I think it'll be an excellent note-taking and light entertainment device. Thank you to everyone who worked on the current release!

ciao ragazzi, esiste una guida o una videoguida? Ho un nvidia shield k1 con andoid 7.0 e vorrei montare LineageOS 16.0. Tuttavia, non sono un esperto di root, l'ultimo dispositivo che ho instradato è stato un Samsung S3. poi sono passato a Apple.

from what i have read they should be compatible with the shield tablet.

I havent tried it out yet myself, but i will soon.

Hope it helps some people.

Is it possible to get those images back ? the romm sounds very promising !

Flashed it but can't install any Gapps version (9.0 pico)) because system partition is too small.
[Shield Tablet Android Development] Scavenger87:
Hi

I also installed the last build from here : Oddsolutions - Shieldtablet with Pico Gapps ( open_gapps-arm-8.1-pico-20210327.zip ) which is 159.8MB without any problems. Which Version of TWRP you are using ?

I using 9.5.0_9-0 after i facing issues with my SD Card on 9.5.1_9-0

About the ROM:

It runs again a lot smoother with again less Green Artifact and Crashes. Its really noticeable that a lot of Work has gone in this new release and it makes me hoping that i can fulfill my promise soon to discontinuing my 15.1 Rom after a official 16.0 Build is out :)
[Shield Tablet Android Development] MultiKoopa:
Oh wow could this breathe some life into my old tablet?! Totally gonna try this
[Shield Tablet Android Development] MultiKoopa:
So what exactly do you do with the Firmware Update link in the first post? How is it separate/different from the Lineage OS build, Recovery file, and Root file?
[Shield Tablet Android Development] MultiKoopa:
installed the latest build from here: https://updater.oddsolutions.us/yellowstone#/devices/shieldtablet/builds

....lots of problems. Settings crashes any time I try to search settings

Keyboard keeps crashing and becoming unusable or being invisible

Not sure what's going on here :\

Also, is there any way to put it into some kind of Optimized/Power Saver mode, like the original Nvidia Android build had? The thing is constantly hot to the touch and the battery life is absolutely atrocious, even while plugged in :O
[Shield Tablet Android Development] MultiKoopa:
Hmm. Seems to be more stable once I set the SD card as portable storage only, and restarted several times. Battery life is still atrocious though. Battery saver helps a little, but plugging in disables battery saver, and the battery drains faster than it can charge.

Is there any way to get LiveDisplay working? or some alternative Night Light thing?
[Shield Tablet Android Development] migo1979:
Same on my Shield K1. Search function in settings doesn't work and some crashes.

There is a service "logd" which needs a lot of CPU usage. After I have killed the process the tablet was smoother. I have renamed the "logd" to "logd_bak" to avoid that the process will start automatically again and then it was better but some apps are not running, e.g. clash of clans...

The setting search with the previous Version was working and clash of clans was also starting but with some graphic flickering.
[Shield Tablet Android Development] migo1979:
The 1 file is the recovery Image *.img and the other is the ROM. You can use TWRP or the lineage recovery to install the ROM...
[Shield Tablet Android Development] wilderson:
It feels really close to being a great room,

with latest; videos only get corrupted when screen is turned off during.

[I've worked this around by using screen off exclusion in KinScreen for video apps]

Some apps fail to launch randomly,

and last but not least rotation gets locked in landscape until screen is turned off an on again.
[Shield Tablet Android Development] MultiKoopa:
weird I don't get ANY of this
[Shield Tablet Android Development] wilderson:
Video artifacts, corruption, green stuff seems like a common thing reading through this thread, app crashing [most likely due to memory management] too.

Rotation fixed itself after reboot.
[Shield Tablet Android Development] wilderson:
The only ROM that has it mostly fixed seems to be AEX 5.8 , even when video gets borked, closing the app fixes it while here you have to restart.

Also, switching OpenGL rendering to Skia under Dev Options seems to completely solve it, but need to test it a bit longer to be certain.
