[ROM] [UNOFFICIAL] LineageOS 15.1 for Shield Tablet OMX | Camera working

[NorTrek]

Hi Everyone

The new October Build is out and ready for download here: October Build

Unfortunately i wasn't able to recover my build signature and had to make a new one. That means everyone needs to do a clean install to use this build just updating as usual isn't possible !

I'm sorry for inconvenience and i did a backup from my signature this time

I wiped everything, but still it crashes a lot when starting upp, then it reboots and get loops.
What can be the problem ? Clean install

Hi

From which version/rom you starting ?

Is your bootloader updated to the latest ?

Which version of twrp you are using ?

Which opengapps package you are using ?

Does it even boot into the homescreen or crash on the bootscreen ?

Bootloader 4.00.2016.04
lineage-15.1-20211018-UNOFFICIAL-shieldtablet
TWRP 3.5.1.9.0
I am trying without gaps, and it still crashes. but when i tested gaps i used the latest Arm Pico version.

I get crashes like:

android.process.media Has Stopped​

Ok interesting which device do you have ? (OG Shield Tablet, LTE or K1)

I never had any of this errors on one of my devices and i own all 3 versions.

For further bugfixing i need a logcat file and please try to reinstall first the factory recovery to exclude a corrupt file system

I have the Wifi K1

I manage to get it working, but now i have a problem
I use the tablet for navigation in my boat, and it get super hot.
And the power usage is as quick as i charge, so i had to turn it off.
What can be the problem since it is running so hot ?

Glad to hear you got it working on one side but on the other side that with the heating up and quick discharge doesnt sound good to me. Which navigation app do you use ?

For me it sounds like your battery is dying from here but i will check that out please do me a favor and dont use this device on your boat until i know if your navigation app is heating up the tablet with my build because i dont want to be responsible when it burns down your boat or you getting lost because of the tablet

As i mentioned before some Games are direct related to the Shield Devices and need some specified libaries which need to be added to this Rom. But for this i really need detailed Errorlogs and even then its not sure i can fix those issues due possible incompatibilities of those libaries with newer android versions than nougat (7.0) but if you send me those logs i can give it a try.

In the October version of the firmware, there are indeed much fewer artifacts in the video. (actually, except for Chrome, as you said)
In terms of game changes, ARK Survival Evolve starts, DOOM 3 BFG Edition does not start due to a broken cache. I deleted the cache, let the game download it on its own and it started. The same cannot be said about Half-Life 2 ep.1 and ep.2. Those, as before, swear at the libraries, they give a sound, but at the same time a black screen (while entering Google Play Games is visible). With Half-Life 2, the same error occurs, but without a black screen, you can play.
I tried to get some information via catlog, I don't know if it will help or not.

In terms of autonomy, smart firmware, I installed a new BM51 battery (from the Xiaomi device) and the tablet began to work on average 5 hours of screen time, the total operating time can be 7 hours, and in standby mode without Wi-Fi, LTE and Bluetooth, it lives for 12 days.

You installed BM51 battery from Xiaomi and it worked?

 

[Xenomorph613]

You installed BM51 battery from Xiaomi and it worked?

Yes, I installed it. Why shouldn't it work?
Gently evaporated the controller from the BM51 battery, it turned out two bare terminals to them, soldered the controller from the tablet directly, then insulated it, put it in the tablet, soldered 4 wires to the tablet board and it all worked. After calibration, the controller itself figured out how to work with it.

So i suppose it works good? Where did you buy the battery?

Hi @Xenomorph613

Thank you for your detailed feedback again and i'm glad to hear you was able made some of the games working again. Also thank you for the logcat file i will check it out as soon as possible. For the next release i was anyway about to ask if you could try your games again because i added some framework stuff from nvidia to make something other working which i will include into my next nightly build because it needs some more polish to get released in a regular release so stay tuned everyone

Also your information about your battery swap is really interesting
Can you maybe do me a favor and check out that battery's capacity with a app like accu battery ?

In any case good work

 

[Xenomorph613]

Привет, [USER = 7100642] @ Xenomorph613 [/ USER]

needs some work to be released in regular release

By the way, it would still be nice to make the frame black, not green, if you really don't fix it right at the root.
In the games Grand Theft Auto, Max Payne, Bully, sometimes a green frame pops up around the edges ... In terms of errors, crashes and other troubles, it does not interfere with playing, but visually it is very annoying.

Hi Everyone

First i wish all of you a happy new year !

Sadly i have to start this year with a sad message for you guys.

I will discontinuing this build because of two reasons:

First reason is that LOS itself has abandoned 15.1 that means there are no more security bulletins in the future as you can see here in the comment section of this unofficial attempt to add the December bulletin :

Bump Security String to 2021-12-05

My second reason is that there is virtually no information and source files available anymore to build good working roms for this K1 chipset which means its very hard (at least for me) to add new features or fix problems like the ones with the hw acceleration that give us those green artifacts.
I also tried to re-add the nvidia games app to my rom which worked first after i tinkered around with the framework of 15.1 by retrofitting the nvidia specific patches you found here for lineage-16.0 :

nvidia-enhancements-q

But after a week and a another update by nvidia to the app it started crashing again while starting up the game sessions. I dont know exactly whats the reason for this as i tried it the last few weeks with different changes on my build but i cant get it working again for some reason.

Thats the reason i will discontinuing my build for this device at least for now and i hope you guys could understand this.

I just want to thank again for all the support that let me build this rom the last year and if someone needs assistance to start his own build can still message me here on this forum and can find my sourcefiles on my github account

Regards
Chris

Sorry to hear that But thank you for all the hard work you put into maintaining this build for us! It really is a pain when you have everything set up just right and an official update ruins your effort. Nevertheless I am thankful you worked on it as long as you did.

Take your well deserved break and Happy New Year!

Sorry to hear that LOS 15.1 has been discontinued and that you will be taking a break for a while. At this point I think I will return to stock

It's sad that you stopped supporting this firmware (
In my opinion, the most adequate firmware that is. Still a little bit to modify ...
Specifically, there is an idea about hw acceleration: add a script to the firmware, they say, when you shake the tablet hard, or turn it abruptly and hard in your hands - hw acceleration restarts.
Well, I found bugs on bluetooth (which is typical on all lineage 14, 15 and 16): some devices do not want to connect, more precisely, there is an endless pairing, no confirmation windows come out. For example, dualshock 4 of the first versions do not connect, dualshock 4 of the second version connects without problems ...
The rest is - well, little things ... On the one hand, solved this way, on the one hand, just leave it as it is and put up with it.


Nvidia games services are no longer used by many) Not exclusive and there are many analogues.
For example, streaming from a computer: Moonlight, AMD Link and others.
It's the same with streaming services.
The nvidia dabbler drawing tool has an analogue - autodesk sketchbook
The only thing is that there is no way to work normally with HDMI. The picture goes both to the matrix of the tablet and to the monitor / TV, but on the second there is a picture with fields.

Currently working on an update [fork] with full Direct Stylus support using this documentation, will be looking to add NV controller support as well if this goes well

Fingers croosed

 

[discomilk]

Added all relevant stylus software and drivers, working on patching the Lineage settings app to include directsylus settings then I can figure out how to trigger a launcher using stylus removal

Edit: Is there a way to replicate HW acceleration issue?

Found the stylus removal trigger and controller triggers in framework-res.apk in /system/framework of latest shield update. Now figuring a way to move these to the latest lineage build we have for the SHIELD.
