HI

So i added the two parts to my sources but still no Hw accleration for me.

Added then in Boardconfig.mk the changes from Artt ZYGOTE_WHITELIST_PATH_EXTRA := "/dev/nvhost-ctrl","/dev/nvmap", but then i got blackscreen at boot. :)

Atm i dont know whats going wrong with my build tryed your Work around display not initializing on boot for loki but still the same any suggestions you can give ?

Greats Triodexe
[Shield Tablet Android Development] Friedensfurz:
[MENTION=1416222]Steel01[/MENTION] Is it possible for you to just release your test build that at least has HW accelleration? Can't wait to try it out ;)
[Shield Tablet Android Development] Steel01:
I may look at an experimental release of 16.0 soon. But there's other issues that make it not really usable beyond testing atm. Like something in the graphics memory management gets lost really easily, so app fail to allocate surfaces and thus fail to start.
[Shield Tablet Android Development] Friedensfurz:
No hassle :) Where can I find your work on the Shieldtablet's resources? Thought you were active on GitLab, but now i was only able to find one initial commit of yours in a Github Lineage Repo :confused:
[Shield Tablet Android Development] Steel01:
It's all on a privately hosted gitlab instance I maintain, not the first party gitlab.com.

https://gitlab.incom.co/CM-Shield

The rest of this is general info to anyone interested. If you know what you're looking for, everything is there in that project/organization. There's also a manifest repo that should be drop in usable for a local manifest (a branch for each supported lineage version). The scripts repo is what I actually use to build. Not all of my local patches are uploaded, though. But only one of them might be relevant (disabling privapp enforcing because opengapps had broken configs last I checked).

patches_lineage.txt:

nvidia-enhancements-p
disable_selinux system/core

patches_lineage_shieldtablet.txt:

265297
268655

I'm not gonna walk through all the steps how to build. There are instructions in the scripts repo. Those patches and picks should be enough to boot 16.0 without gapps. Standard disclaimer to any that try to build. I haven't upload an experimental build because I don't think it's ready for even that yet. But anyone that wants to build is welcome to do so. All of my code is freely available. And as always, patches and bug fixes are welcome.

Edit: I should make another disclaimer here. CM-Shield is my work in progress area / holding tank. I make no guarantees that anything there even compiles, much less boots. That said, I do try pretty hard to keep things in sane shape. But it's virtually always in flux, so it would be possible to sync while I'm in the middle of working on something and a build fails.

Hi

Hmm your right i tryed the Stock 0 Image too today cause i got problems with second galaxy with my rom not starting and audio crackling.

Now with the Stock it runs smoothy maybe i try to use Graphics/Audio stack from this and do a testbuild but i think it wouldnt boot :)

Greats Triodexe
[Shield Tablet Android Development] _benedict_:
Hi!

I think I speak in the names of many when I say we really truly appreciate the work you developers have put in the device.

While I hope to see 16.0 landing to the device someday, I'd rather stress today that I hope you are doing well in this dark period of time.

Kind thoughts to everyone and each of you guys.

Problem with Lienage 15.1 on Shield Tablet 1st gen

Hi, I am trying to install Lineage 15.1 on my Shield Tablet 1st gen. I have problem with install zip package. I have messeage zip signature verification failed. Does it mean that Lienage 15.1 is not compatibile with my tablet? I have TWRP ver 3.3.1-0.
[Shield Tablet Android Development] j-cron:
Hello Marek,

It looks like the Shield Tablet isn't currently supported by Lineage OS if you look at their main website. I believe [MENTION=1416222]Steel01[/MENTION] is working hard to bring us a working version when he has time. I think if you keep an eye on this thread he will eventually release a build we can try out.
[Shield Tablet Android Development] Entodoays:
My Nvidia Shield tablet running LOS 15.1 is giving me an error message when opening the camera: "Camera error: cannot connect to camera". Till now I tried clearing the cache of the camera app and of the system (through TWRP). Any hints on how to resolve this issue?
[Shield Tablet Android Development] dimeness:
HI everyone.

I have big problem. I don't install gapps.

"Gapps installation failed"

Error code: 64 - Unmounting partitions,

Updater process ended with Error: 64.

Error installing zip file '/external_sd/open_gapps-arm64-8.1-pico-20200508.zip'

Can somebody help me in this case?
[Shield Tablet Android Development] Adai0:
You need to use the correct version of Open GApps. The Shield Tablet is not an arm64 device. It's arm.
[Shield Tablet Android Development] M4rkusX:
Any progress in those rough times?
[Shield Tablet Android Development] Travel gnome:
will this work on the original shield tablet also or only the K1 version ?
[Shield Tablet Android Development] TheKicKer69:
It will; I use it on my original Shield Tablet
[Shield Tablet Android Development] Alex.Tux:
as an alternative to this ROM which one do you recommend to use?
[Shield Tablet Android Development] john_matrix:
This one:

https://xdaforums.com/shield-tablet/development/rom-lineage-15-1-nvidia-shield-tablet-t4058801

Works fine, have some bugs but better than nothing.

Hope Steel001 is still developping its own version of LOS.
[Shield Tablet Android Development] multiwirth:
This is almost stable it had a few crashes especially when you play netflix and let the screen go off (it won't wake and reboot after 30 seconds).

As long as you close the app before entering sleep mode, it should be fine and battery life isn't that bad thanks to OMX partially working (as i said avoid sleep mode)

Playing standard video files (9gag) will crash OMX sometimes and videos won't be played right > reboot

Overall it's still useable.
[Shield Tablet Android Development] tit0um:
my deepest appreciation to you [MENTION=1416222]Steel01[/MENTION]

my shield was bitting dust and i wanted to use it for nightly farm on 7Ds...it was unresponsive and garbage.

i was lucky enough to bump on the reddit link for previous 14.1 lineageOs based on your work and it is a piece of art!

7DS has been installed and tablet is ubber responsive.

it is unbelievable that such big company as Nvidia with their army were not able to go further as you did alone.

again thank you!

Hello

i'm trying to download this image as i'm new with it

but couldn't find the download link on the official website

Any help please, Thanks
[Shield Tablet Android Development] ogremalfeitor:
They no longer offer builds of LOS for this device, although one can still build it from source. Try the 14.1 build from the following thread, it's a fairly recent build. I'm using it with my K1 and it's very clean, stable and quite battery friendly:

https://xdaforums.com/shield-tablet/development/rom-lineageos-14-1-15-1-shield-tablet-t3950786

Instead of using the root add-on mentioned there, you can flash Magisk if you want root, works great:

https://github.com/topjohnwu/Magisk/releases

Best of luck.
[Shield Tablet Android Development] M4rkusX:
That was 8 month ago. Is this (still marked official) build abondoned by Steel01?
[Shield Tablet Android Development] Scavenger87:
Hi

Its true this Thread is a bit abandoned by the OP at the moment but the reason is that LineageOS quit the official Support of our Tablet after the developer faced some heavy issues to build a stable ROM based on 15.1 and newer. But from what i read recently Steel01 is still working on it from time to time besides his Shield TV Roms. When i saw it right he made some progress on a Android 9 based Rom which would be LinageOS 16.

You can see on his Gitlab Group here he is still working on it : https://gitlab.incom.co/CM-Shield

Its even possible to download his source to build your own rom from that side to test it out. But i'm not able at the moment due the lack of a proper set up build machine and the expirience thats needed to do that.

But i think it would be the best to wait until he makes a official announcement here

In the meantime you could try the unofficial version of 14.1 keeping updated by The-Saint2k almost every Month with a Security Patch refresh.

[Shield Tablet Android Development] 2mk_shield:
No SIM detected with 14.1

Hello,

I'm struggeling with no SIM card detected after updating to LineageOS 14.1 on my Shield Tablet LTE (RoW version).

Maybe I missed any posts regarding this issue but I was searching for hours and did not find anything on this topic related to this device.

Could anyone write a way how to get the SIM active on 14.1, please?
[Shield Tablet Android Development] Scavenger87:
I dont know about the compatibility of the LineageOS to the SIM Slots and i cant test it out at the moment because the SIM Slot on my LTE Tablet is broken but i recently saw a "No Service" message on my Tablet that has Triodexe's AEX Extended 5.8 Rom installed. Its a stable Android 8.1 based Rom with the HW Acceleration fixed.

Maybe you wanna give it a try and see if it brings your SIM Card back to life ;)
[Shield Tablet Android Development] HeroXth:
heya, perhaps try things through earlier recovery image? 3.1.1.1.
[Shield Tablet Android Development] lilmonkw:
Hello! I've run into some trouble while flashing a custom rom and a few mods. I broke things in the end, but I might as well be right on how to fix them. And I would really appreciate your help!

I ask for the "mmcblk0p24" file from the new version of the Nvidia Shield Tablet, K1, 16GB specifically. (The one that came out without the stylus.)

HERE'S THE INSTRUCTION ON HOW TO COPY THE FILE:

1. Enter TWRP

2. Mount System if necessary

3. Advanced -> File Manager

4. Path to the file: /dev/block/mmcblk0p24 (you can simply copy it straight to /sdcard)

IF YOU HAVE mmcblk0p25 AS WELL, MENTION IT! In my case, I don't have the mmcblk0p25 file. That means I need the mmcblk0p24 file that comes from the system without mmcblk0p25 either. So, if you are willing to share the file I requested, make sure you DON'T have the mmcblk0p25 file in your /blocks folder and your device is a 16GB version.

Though it could be useful for somebody else, there's no harm in posting it anyway.

That's it! Nothing bad is going to happen to your device. Simply copy the file!

It also would be very nice of someone to fully upload the "/blocks" folder. It could be very useful for restoring the tablet for other people!

Thanks in advance!
[Shield Tablet Android Development] asengupt:
Unfortunately I don't play games on this device - I bought it mainly to take notes at work - only device at its price point (back when I bought this) with LTE support and a stylus for note-taking. I have hooked it up to HDMI displays to watch videos though and that works great. I moved from Stock to BlissPop to Bliss to Lineage 13 and now Lineage 14.1 and by far this one is the best performing ROM I have seen based on what I use it for, so I expect gaming to be snappy as well. Just to test, I installed Riptide GP2 (yeah I know - not much of a gamer) and it worked smoothly with no lags or jitter at all.

I wish the deep sleep issue can be fixed - if there is anything I can look into please let me know!

J

---------- Post added at 09:50 AM ---------- Previous post was at 09:47 AM ----------

PS before I installed the unofficial 14.1 - I was using the Lineage 13 build - and it had the random reboot problem that has completely disappeared in this version so other than the sleep problem I have no issues what so ever. Did realize that the camera doesn't work when I tried to Skype once, but other than that haven't noticed any other problems.

J
[Shield Tablet Android Development] didicola:
thanks for your time to test some things!

also what about charging issues? does it charge fast like on 5.1.1 ( iuse now 5.1.1 stock)

one last thing you try please a game if it loads and opens ? this
[Shield Tablet Android Development] asengupt:
No charging issue - charges from 15% to full in about 3 hours using a standard 1Amp charger. I have no idea where my original Nvidia charger is :confused: so I can't say how much faster it would charge with a 2.1 or 2.5amp charger.

The Disney game loaded and worked fine for all the 30 seconds or so that I used it :o but it wanted to download over 1G of content and I didn't have space or time so I unfortunately canceled the download.

If only the sleep issue can be fixed, this would be a perfect ROM for the Shield.

J
[Shield Tablet Android Development] Steel01:
So, battery life is an important factor and I will try to look into it. But I don't think it's a blocker issue. Those pics don't really tell me anything. But I don't think I've merged everything needed for proper doze either. I'll get to it eventually.
[Shield Tablet Android Development] didicola:
can you plz make the next build like stock lineage not to be identified as rooted device even without flashed supersu

the previous lineage14.1 had was identified as rooted (i use some apps that dont like rooted devices)
[Shield Tablet Android Development] FoxyDrew:
I personally use camera A LOT, and that's the only reason I stay on stock lol
[Shield Tablet Android Development] kristofpetho:
Doze is not yet enabled by [MENTION=1416222]Steel01[/MENTION], so most likely that is the cause.
[Shield Tablet Android Development] Spadizzle:
Update is failing or is their another way on the unofficial 14.1. This has been a good experience. Nice and stable besides the obvious issues.
[Shield Tablet Android Development] ouphe:
Steel01, thanks for building this. I installed lineage-14.1-20170406 without any problems. I'll play around with it the next few days.

Edit: Oh wow, this feels fast.

- no video in Netflix app, only sound.

- can't install opengapps full, not enough size on system partition. Nano works fine

- Videos embedded in websites crash in Chrome when skipping to a certain point, audio continues.
[Shield Tablet Android Development] flatratte82:
Thank you for your effort on this. How can I compile it by my own?

Currently there is no shieldtablet in the build menu :(
[Shield Tablet Android Development] Steel01:
I should probably add back the vendorsetup script to populate the lunch menu. But I don't use the menu myself. Just run:

lunch lineage_shieldtablet-userdebug

instead of the menu. Then build as normal.
[Shield Tablet Android Development] didicola:
will there be a new version? (official lineage or unofficcial)
[Shield Tablet Android Development] Cm4nXD:
Yeah I want a nougat build!
[Shield Tablet Android Development] keelsonkeelson:
I want a pony!
[Shield Tablet Android Development] flatratte82:
I would appreciate it if it's added to the vendorsetup script. The reason is that I would like to build Resurrection Remixi for the shieldtablet. RR is based on lineageOS and the build failes because of the missing entry in the build menu.

If you could do that it would be really great :)
[Shield Tablet Android Development] fpozar:
So there is this new fix for camera here on the xda forums (shield tab android development).I hope this can prove to be helpful for you Steel :)
[Shield Tablet Android Development] Spadizzle:
Your not talking about this one?

https://xdaforums.com/shield-tablet/development/fix-k1camera-aosp-14-14-1-cm-based-14-t3503803

Its from Nov last year if that's the case.

I tried carbon rom and cam worked. I think that was the rom, but wasn't stable enough.

Would be sweet if lineage gets it to work!
[Shield Tablet Android Development] flatratte82:
Them cam is already working on Dirty Uniorns. So there might be a solution for it.
[Shield Tablet Android Development] fpozar:
Oh dang, my bad, it really is from november. But still, it might be useful.
[Shield Tablet Android Development] Steel01:
I have no idea what that camera zip is doing. The problem with the camera using the old blobs involves the major media framework revamp that came with N. Flashing a couple blobs and an apk isn't going to properly/completely fix that. I had it somewhat working, like preview and taking stills worked, but saving videos failed completely. Official DU, Carbon, and such are using those older blobs. Using newer blobs fixes a bunch of stuff, but the camera won't even initialize. If I read the errors correctly, the hardware accelerated encoder interface is failing to set up correctly. AICP, Tesla, and my unofficial Lineage builds are using the newer blobs. I'm hoping one of these days, I'll be able to figure out the issue. Just haven't had success yet, and precious little time to even try.

I do still plan on releasing newer builds, but there's been issues with 7.1.2. Like lmk was murdering all the things on one of my recent builds. My current one seems more stable, but I'm going to run it for a few more days before releasing another build. See above comment about time, though. No guarantees on etas at all.
[Shield Tablet Android Development] Dabman:
Can someone upload latest stable OFFICIAL build of LineageOS and Gapps pico for it?
[Shield Tablet Android Development] filjusz:
Thank you for your hard work. Still running your 14.1 official build for ST. Sadly there's no more development... ;(

[Shield Tablet Android Development] MultiKoopa:
So uh. I noticed that there's a LineageOS 18.1 ROM available for the Shield Tablet? Is this really real??

Anybody using it? How is it?
[Shield Tablet Android Development] Steel01:
'ROM' is speaking quite loosely. The repos exist. It builds, it boots. The UI is currently unusable. Don't get too hyped. There's less major blocking bugs than there has been for a while, but there's still major blocking bugs. And no one knows whether someone will be able to fix them or not. But yes, some of us are still trying.
[Shield Tablet Android Development] MultiKoopa:
never give up

never surrender
[Shield Tablet Android Development] tit0um:
tbh never understood why nvidia has given up on that table when they keep supporting the shield tv.

is the hardware that different ?
[Shield Tablet Android Development] MultiKoopa:
it came out in 2014. It's 8 years old. Nothing can be supported forever.

It is bizarre that they never made another tablet though

(in before somebody says "what do you mean? They made the Nintendo Switch hahahah")
[Shield Tablet Android Development] tit0um:
yeah but my shield tv pro is from 2015 and still rocking and getting update.

i think they share pertty same hardware...would have been nice to be able to convert it as a shield tv with screen.
[Shield Tablet Android Development] YottaEngineer:
Using the tablet now, with android 9 and only to read I forget that it only has 2Gb of ram and it is 32 bits.

Apart from the Switch, they probably saw that the tablet market was dying. It has now in the last years kind of revived with the "Pro" obssesion. But being gaming focused, a X1 tablet stands no chance against big gaming phones, which are better in every way.
[Shield Tablet Android Development] MultiKoopa:
I'm hoping the Pixel tablet is decent.
[Shield Tablet Android Development] Scavenger87:
Thats because every Shield TV has at least an X1 SOC instead of the K1 that this Tablet and a hand full of other devices like the first xiaomi mi pad is using.

The X1 is 64bit instead of 32Bit like the K1.

In fact they worked on a successor with a X1 in it but if i remember right they discontinued the development after they made the deal with Nintendo to serve they're SOC to the Switch which is also a X1 and later a X1+

From what i know the main problem in further development of this tablet and K1 devices in general is the fact the vendor blobs never where updated and worked on to fit a newer android version after 7.0 nougat.

When i worked on my own version of LOS 15.1 i got lot of troubles like artifacts on video playback which is IMHO caused by the .so files that never got updated to work correct with android 8 oreo and newer.

Maybe I'm wrong and @Steel01 can correct me here but i would say because of those files the devices is running in some kind of memory leak and affecting the playback and later crashing the whole device which leading to a soft reboot at least on my rom's.

The Problem with those .so files (shared objects) is that they are compiled already an only Nvidia itself has the raw files and there is no way to open them up to maybe fix this problem.

But like i said that's my experience so far and i could be wrong about this
[Shield Tablet Android Development] YottaEngineer:
So Android 12L in the K1 is immpossible then :(
[Shield Tablet Android Development] Steel01:
Not outright impossible, but virtually so. Someone would have to backport ebpf to the 3.10 kernel and that's a monumental task no one wants to do. So only devices that use the 4.4 kernel or newer can currently use Android 12.
[Shield Tablet Android Development] filjusz:
But android 11 is possible?
[Shield Tablet Android Development] Steel01:
Sure. Questions about code related to that is what necrothreaded the conversation. 11 boots, but isn't usable atm. No one that's looked at the current issues knows why the ui is unusable, though.
[Shield Tablet Android Development] Saison2018:
Sorry for the stupid question (i am not a developer): I suppose this is not as simple as installing another launcher?

I ask because I have two tablets with this current rom, and one of them was unstable with default LOS launcher. I installed another launcher (Star Launcher Prime) and this is not perfect, but far better than before.

Please excuses me if this is silly, I just want to try to help, even with my little knowledge.
[Shield Tablet Android Development] YottaEngineer:
The launcher is just a skin for the homescreen. LineageOS is an entire operating system, derived from Android. So it is much complcated to make compatible with each device, especially an old one like the Shield K1. Also, don't worry about asking questions. I am also not a developer, I only read tutorials ;) from other people. But by reading and experimenting we all learn.
[Shield Tablet Android Development] 1sak:
Is it possible to install Android TV on this tablet?
[Shield Tablet Android Development] n0credit:
If I remember correctly back in the day Steel did a couple of builds, maybe android 6 or 7 (I'm not sure sorry), so if that's not a problem maybe you could search around.
[Shield Tablet Android Development] MultiKoopa:
I'm wondering why checking for update in the System menu for LineageOS 16 on the Shield shows 18.1 is available? Why is that listed as an official available build if it only boots and doesn't even have a usable UI?
[Shield Tablet Android Development] Scavenger87:
Thats because he linked the update service with his own ota server most likely the same from his website.

Those builds are NO official releases from the Team of LineageOS and only for testing purposes
[Shield Tablet Android Development] nunitofiman:
Have you tried version 16.1 that they have on their website? have problems or is it better to stay with 15.1 (or 14.1)
[Shield Tablet Android Development] filjusz:
Where it is available?
[Shield Tablet Android Development] nunitofiman:
I just installed. feels fluid (no more than 15.1, which considers it perfect) no camera, no problems open_gapps -arm-9.0-pico- 20220215
