Only problem I'm having is with Disney+...keep getting error 83...I'm also having some pops in audio in regards to emulation using mupen. Didn't have those using los 14.

Anyone getting disney+ to work using this rom?
[Shield Tablet Android Development] Triodexe:
Hi

Guess this problem comes from the not completly working Widewine Drm.

The Audio Problems comes from Buffer underruns but i didnt find a way to fix it curios is with the Stock Rom from 2014 Version 0.0.0 all these Problems never happen so my guess its crappy Driver from Nvidia and since Nvidia stoped development for the T124 we only can try to get the T210 Drivers to work correct for our Shields.

I tryed building a Rom with this Stockimage drivers but no way to get them to work with Oreo based Roms.

Bad that my knowledge in Coding is near 0% so i can only use the Stuff that comes from Steel01/Artemka2008

Thanks for the update! I guess I'll stop trying to figure it out for now... :laugh:

Please keep up the great work!!! Much appreciated.
[Shield Tablet Android Development] WilderSu:
What level of Widevine is the stock ROM on anyone knows? Disney+ requires L1 [quite infamously], nothing else will work. AFAIK unlocking bootloader sets it to L3 [ somebody please correct me if I'm wrong ]
[Shield Tablet Android Development] rlw6534:
Stock latest Nougat is L1. It remains L1 with unlocked bootloader and Magisk root.
[Shield Tablet Android Development] Triodexe:
Hi

Widewine Stock is Level 1 samke like this Rom Drm Tools shows Widewine as correct Lvl 1 Crypto works too when you look at Logcat but at some Point there comes a Unknown Error For WDMCrypto.

The Crazy thing is it has worked for me the Firsttime i flashed it but now i got same Error 15001 on Netflix.

Sometimes my feelings are Netflix changed something on there Serverside and we got rejected from the Servers

I've tried it and now my tablet is not booting, it can't even reboot to recovery.

I've then tried to flash stock recovery, boot, system and blob but it still can't boot.

I've flashed many devices but it's the first time I cannot boot to recovery.

The tablet seems to be bricked ?

Anyone have an idea to revive it ?

Thanks
[Shield Tablet Android Development] Triodexe:
Hi

Sorry to hear that never had any of this problems.

Did you flashed the Stock Recovery with the flash-all.bat batch file or single ?

Btw as long you can go to the Bootloader your not bricked :)

The command says "flash userdata userdata.img" but userdata.img does not exist so how can it could work ?

Thanks
[Shield Tablet Android Development] Triodexe:
Hi

Your wrong its a erase of userdata not flash.

Here are the commands from the Flash-All Batch.

fastboot flash recovery recovery.img

fastboot flash boot boot.img

fastboot flash system system.img

fastboot erase userdata

fastboot flash staging blob

Hello, the ROM video performance is awesome!

But the battery drain is not :D (battery is going empty in 1 day and half without using it)

Is there something to do to improve it?

Thanks!

Hi

Guess there is some Wakelook/Alarm wakes up your device install betterbatterystats

and look what wakes up your device.

Look at Partial Wakelooks most of them should be under 2%

My ScreenOff time is 94% Deepsleep and it last calculated around 14 Days showed by Accu Battery App

Running a clean flash with no root.

Having a problem where after leaving the tablet to idle for a long time it will turn off.

Not sure if the display driver crashed or not.

Then need to force reboot, somehow need to hold power to off it and hold to on again.

Turn on, Nvidia logo, Lineage logo.

Lockscreen, unlock.

Blank homescreen with wallpaper.

Then the screen starts dimming to black.

Frantic tapping, swiping, power button, swiping.

Till I hear the unlock sound, then more frantic tapping.

The screen lights up and its some random app.

I exit and use as normal.

(Until I leave it to find it black again many hours later, repeat)

Happened 2 times already.

Just flashed yesterday, totally clean slate, not root no TiBu restores.

Just gotten the 3rd time, this time can't on because the battery is drained.

I had the expanded desktop on to hide navbar, couldn't be the cause, right?

Could be the Display Driver but first try to change the Io Sheduler guess they are not so stable

Even with that my tablet bootloops. Since I flashed the rom and dtb of the OP the tablet can't even boot to recovery. How can I revert to stock dtb ?

Thanks
[Shield Tablet Android Development] Triodexe:
Hi

The Stock Dtb is inside the Boot.img/Blobs normaly no need to flash seperatly but you could try this Dtb

Yo, my tablet got micro-bricked as well somehow, I flashed this dtb and I can get into recovery again fyi
[Shield Tablet Android Development] Triodexe:
Hi

Did you have The Y or the B01 Battery ?

Greats Triodexe
[Shield Tablet Android Development] Dhalsim43:
Indeed, the bootloop was caused by the dtb file. My tablet is now working again ?

I suggest you to modify the OP : the dtb should not be flashed on the Shield Tablet K1
[Shield Tablet Android Development] Triodexe:
Hmm i Have the Shield K1 Wifi with B01 Battery and no Problem with the Dtb :)

Curios that not every Shield is the same

[Shield Tablet Android Development] Dhalsim43:
Does encryption/decryption work ?
[Shield Tablet Android Development] jemail:
Maybe the tablets with the dtb problems are the LTE variants?
[Shield Tablet Android Development] Triodexe:
Hi

The changes i did in the Dtb are only related to the battery Dts and Charger Files Voltage/Ampere Ramps.

Thats why i dont understand that this causes the Bootloops but maybe there is some hidden Code that controls if this Values are out of alowed range so the Kernel crashes.

For the Crypto Question i didnt Test this but i guess Hardware Crypto dosnt work.

Greats Triodexe
[Shield Tablet Android Development] airtower:
[MENTION=7877387]Triodexe[/MENTION] the modified dtb is optional though right? The OP, before you edited it, kind of made it seem compulsory. At least that's how I read it, but I didn't have any issues. Some might be willing to forego the chance of working QC to avoid headaches.
[Shield Tablet Android Development] Triodexe:
Hi

The Dtb is only needed when Qc2 still not work after flash Rom

I have no problems with the Dtb but some pplz reported they got Bootloop not working recovery after flash my Dtb thats why i put a link for the Old Dtb from Werewolf as Fix.

Hello is there a new monthly build comming? Also can anyone mirror to a chromecast? If not, to me this is a bug that's been present forever.
[Shield Tablet Android Development] Triodexe:
Hi

Not from me this was only a Test Build to see if Netflix HD working on Lineage Branch.

Maybe Later when the current problems with Nvidia Drivers fixed i continue Building a new Rom .

My Main Rom i work with is Aosp Extended but since there are some Overlays prevents Netflix to run in HD Modus (Sound is Ok but no Video is seeing) i will switch to Aicp and try to get this working.

Status for AICP 14.0 is it boots but crashes right after the Bootanimation.

So i stop currently building any Rom and wait for Steel01 to finish all the work on the Device/Vendor Files cause my knowledge in Coding is not good enough. :)

[Shield Tablet Android Development] Dhalsim43:
I've tested this rom and I wouldn't say that video HW decoding is fixed ; some of my video apps have problems : sounds distortion and jerky video ; so I'm back to LOS 14.1
[Shield Tablet Android Development] Triodexe:
HI

Your right not all Video Apps working correct currently but thats a combination of not right working Widewine Drm and Keymaster.

And some Problems that Videos goes Blackscreen when any Overlays are active like Livedisplay,Ambientdisplay or Navbar Overlays.

The HW Accleration for Videos itself working most of time correct.

[Shield Tablet Android Development] multiwirth:
After some testing i can tell OMX is working great but still breaks from time to time.

When playing netflix and entering sleep mode, it will crash and reboot after some time.

Closing the video before entering sleep is a workaround.

That was expected though.

But i found another strange bug - when in landscape mode and the dpi set to "small" tapping a textbox to force the keyboard to show up will break the functionality of the navbar.

It's similar to what i've seen on icosa (nintendo switch) android builds but wasn't expecting this on the shield tablet :laugh:

see here for more details.

Will there be fixes for bugs?

Nvidia games periodically beats an error, regardless whether I try to run it or not.

All sorts of minor bugs with the interface (especially the launcher, which is not friendly with the horizontal mode. There is at least such a launcher play.google.com/store/apps/details?id=com.jasonkung.launcher3(actually it is in the original firmware))

A HUGE and extremely unpleasant bug - it is not possible to format a microSD card (on not small 64gb) ...

[Shield Tablet Android Development] grimreaper1014:
I know support for the nvidia shield is about dead. However, I still like using it here and there to play some games. So does my son. I'm having two issues. One the tablet is getting slow as Moses. Which I know is because it is getting old. Is there any custom kernels that allow overclocking that would work with this build?

The second issue I am having is with flashing the file for quick charge. I'm on Windows 10. For some reason I have always had a problem getting ADB to run on Windows 10. I installed the drivers from NVIDIA. The device was recognized in Windows. I was able to issue the command to restart the tablet into the bootloader. However, when I start the commands to flash the Quick Charge zip. It continuously says "waiting on device". When I went back into Windows it shows ADB driver has a yellow exclamation point. So the driver didn't install correctly or something. I tried uninstalling and reinstall which didnt work. I also completely uninstalled and tried the universal drivers which also didnt work. It would be nice to get quick charge working as it takes forever for this thing to charge even with a high powered charging block and cable.

Flashed this last thursday on my K1. Works great as far as I have tried, the only bugs I have noticed is the audio is out of sync when using bluetooth earphones and sometimes a totally random app is crashing on launch, when that happens I just restart the app and then it's working fine.

Thanks a lot, it seems to work great: before, I could only charge the tablet with the standby power port of the HP 820 G2 I wanted to give to my son. With the DTB you've provided, I can charge the tablet with the standby power port of my Thinkpad :)

shield controller

hi, I have installed the rom. everything works. I want connect the Nvidia Shield Controller. there's a way?
[Shield Tablet Android Development] Scavenger87:
Hi

I dont have installed that exact Rom but i think its like on every Custom Rom at the moment that you have to use the USB Cable in combination with a OTG Adapter on the first series Controller.

The new one you can connect normal over Bluetooth.

Sadly there is no Rom around yet where you can use the in my opinion good Controller Apps especially the buid-in Mapper app is something i really miss but you can use Panda Gamepad Pro from the Playstore

Big thanks for nice ROM

Thank you so much for this ROM. I have two NVidia Shield Tablets for my young kids to watch videos and some interactive learning apps/games. This will do perfectly I hope. I've only been running it for 1 hour but it feels great so far. I used Gapps nano. Installed FDroid for open source apps, and will install Aurora Store next for any other apps. Installed NewPipe and it runs well at 1080p.

Superb, thanks again for all the hard work. Big thanks to LineageOS too. I researched and bought this make & model just for the LineageOS support.

---------- Post added at 09:11 PM ---------- Previous post was at 08:23 PM ----------

I forgot how much I love LineageOS. I used it on some (x4) Galaxy Note 3 phones that I bought cheap 2nd hand and gave away (except one that I use for testing) to people that needed them. The Note 3 was my daily driver even though it was so old, I loved the screen on it. I don't miss the camera which was dated when I started using it (many years after it came out). But ultimately I stopped using it because the compass had a known issue (especially with Google maps) where it would go out of calibration by 180 degrees all the time. I missed a flight once because of it and so I could not use it as daily driver after that. Now I'm on my 2nd Nokia since then and whilst I like the Android One experience, I do miss LOS.

My Nokia 7 Plus has developed an issue whereby the touchscreen locks up and I need to lock the phone and unlock to get it working again, only takes a few seconds but it's incredably annoying. I've lost photo and video opportunities because of it, and when using Sat Nav in the car, it is dangerous. So based on how good this Unofficial LOS Rom is, I would consider installing on my Nokia to work around the touchscreen bug. But I worry that my Camera will not work as well as on stock ROM.

Next phone I buy will probably be officially supported by LineageOS. I dream of the day I can run some other pure Linux OS (e.g. Ubuntu Touch/Sailfish OS).
[Shield Tablet Android Development] michie:
Imho this rom will not get any updates anymore unless the OP tells me otherwise, than i will remove this post.

[Shield Tablet Android Development] Scavenger87:
Hi michie

That sounds interesting is on those builds also the OMX fixed ?

If yes i'm glad to give it a try on one of my tablets :)
[Shield Tablet Android Development] michie:
Dont seem to be working indeed, google soft codecs are enabled. OTA updates are available in the rom and it looks like it might bump up to LOS 16 soon.
[Shield Tablet Android Development] Scavenger87:
Ok thanks for the fast reply i give it definitly a try also the part about the OTA is interesting.

You know the name of the builder ?
[Shield Tablet Android Development] player594:
Does this work for the Shield K1?
[Shield Tablet Android Development] michie:
Yes, this is for the Shield K1 (AKA Shield tablet). It runs perfectly on mine together with the lineage recovery which they also offer as a download. Gapps are already included.

This is from the team who also posted the LOS16 update for the Atap in the original android development section.
[Shield Tablet Android Development] Disrupthor:
Unfortunately HW Acceleration isn't enabled... :(
[Shield Tablet Android Development] Scavenger87:
The Rom works really nice on my Shield K1 i even was able to login and load the gamelist of the Nvidia Games App and was able to start a game but it crashes everytime with the Errorcode 11 (80320013).

I checked it multiple times and also with a tablet that has the OEM Rom where it worked.

I tried to fix this issue by turning on " Force GPU rendering" and "Set GPU Renderer to OpenGL (skia)" but it doesnt help

Where did you see its disabled ?

But yes it would might explain the issue with the NvGames App.

If we get this Rom with the HW Acceleration fixed it would be perfect in my opinion.

Especially when Nvidia Games works ;)
[Shield Tablet Android Development] Scavenger87:
I tested it today and the tegra k1 is able to play 1080p60 smooth on the oem rom and on roms with hw acceleration working
[Shield Tablet Android Development] Scavenger87:
In the official LineageOS Thread by Steel01 i found this workaround that should fix the hw acceleration and i was about to try it myself with that Rom posted by michie.

The first thing should be easy by just editing out the !-- from the media_codecs.xml found in the system/etc folder.

But i stucked on the second part because i dint found a folder called libm or a file called libm.arm.map either anywhere. I think its maybe some kind of libary you load from the git when you build a rom.

Maybe some of you more expirienced guys could give me a hint if i'm on the right track or completely lost already :confused:

Я бы свои два планшета давно перевел бы на Android 8.1.0, но вот блин косяк прям огромный есть: не возможно формировать карту памяти (microsd) как внутреннюю, как это можно было сделать на стоковых 6.0.1/7.0 и на кастомных 6.0.1/7.1.2

Вот есть две карточки - Leefpro 64gb и Samsung evo plus 64gb и система на обе карточки ругается, мол не возможно форматировать диск, или ошибка форматирования, прям во время форматирования для внутреннего носителя.

Очень хотелось бы какой нибудь фикс этой штуки или мануал как это исправить самостоятельно...

I would have transferred my two tablets to Android 8.1.0 a long time ago, but there is a huge damn jamb: it is not possible to form a memory card (microsd) as an internal one, as it could be done on stock 6.0.1 / 7.0 and on custom 6.0.1 / 7.1.2

There are two cards - Leefpro 64gb and Samsung evo plus 64gb, and the system swears at both cards, saying it is not possible to format the disk, or a formatting error, right during formatting for the internal media.

I would very much like some kind of fix of this thing or a manual on how to fix it yourself ...
[Shield Tablet Android Development] michie:
Looks like a 16.0 build appeared today.

Edit:

Looks like it's working with HW acceleration (nvidia OMX) and camera. The system needs some time to settle after install and there are hickups here and there but seems very promising. Make sure to give the tablet some rest after setup, it seems to be working better and faster after leaving it alone for about 30min after initial setup.
[Shield Tablet Android Development] john_matrix:
I have tried the LOS 16 version and HW acceleration seems broken as 1080p60fps Youtube videos show blocky and greeny.

Sometimes, there is no issues but mainly, videos are not played correctly.
[Shield Tablet Android Development] michie:
Reboot your tablet. HW acceleration works most of the time but sometimes it's broken yes. Most videos I played work on 1080p60fps but after I gave the system enough time to settle.
[Shield Tablet Android Development] Scavenger87:
I tested this ROM the last two days and i really have to say this could be the One we all looking for to keep this Tablet alive in the future :)

Of course it still need some polish and its still not that stable in case of hw acceleration and it crashed on some apps randomly but i was able to use Nvidia Games for a little Gamesession.

It also is helping when you just restart the App itself at Settings -> Apps -> Appname -> Close App

With that i was able to fix the Greenscreens and Artefacts on the Screens temporarly.

I think there is something wrong with the Vulcan part of the HW Acceleration because you could see it at the "Overhead Vulcan Benchmark" at 3DMark. There are some Graphic glitches as well starting at around 15000 Draw Calls per Frames everytime.

I installed it on one of my K1's and i install it soon to one of the OG's to see if there is any difference.

But like i said i looking really forward to use this ROM permanent when its done and i still available for Beta Testing on all Shield devices and sending Log Files to help develope this ROM :)
