[Shield Tablet Android Development] Ikarbb:
I can try to add some useful input on what I did to make gaming much smoother. I mostly run Summoners War and Knights Chronicle (Summoners War has a mode that is very RAM intensive to the point where the keyboard failed to even load, but I fixed that).

First off, the devs that have been supporting LOS14.1 on this tablet made this the ROM to use as a daily driver (in my experience, the BEST ROM). Everything works great. The best way to debug when apps force close is to check what is running in the background at the same time the game is loaded. Limit those apps as best as possible. Another key issue is to check the values in LOW MEMORY KILLER. This is a set of rules built into android to keep RAM occupied for later use, and you want to have as much of this as possible (keep it full). Easy way to do this is Magisk Root + Kernel KA-MOD App + LMK tweaks (within the KA-MOD app). There are 5 presets, and you want the lightest option. That will only kill off applications when RAM reaches that threshold. There are also other guides on ways to tweak LMK all over the forums. This tablet only has 2GB of RAM.

After I made those corrections, I no longer have apps force closing on me, and I can type will playing games with chat features.

Some users noticed better performance when they disabled SWAP on the tablet, and this can be done through the KA-MOD app as well. A magisk module you can flash known as SWAP torpedo also works. Also enabling DOZE on Google Play Services really helps. I hope these help. The problem seems to be in the RAM and RAM type the tablet uses, even on Stock these issues occur. I have a HTC M8 with 2GB of RAM that never has those issues, but also doesn't "game" as well as the shield.
[Shield Tablet Android Development] mixtopher21:
Wow thank you for this reply! Although most of what you said is alien to me, perhaps you could dumb it down a little? I'd like to try some of what you said but might need help understanding some of it. Should I start with this KA-Mod you mentioned?

Hi there!

I recently took out my Shield Tablet (Original one) and installed this ROM. I will just use it for Netflix which worked without any problem. After maybe 1 - 2 hours later I tried to watch a show and now I just have subtitles and sound but no picture. Is this a known issue?

Google Play Store keeps force closing after latest system update (Sep 1st). Cleared cash / data and wiped cash in recovery, still force closing. Playstore useless right now. Anyone with same problem?
[Shield Tablet Android Development] Adai0:
I am fine on 14.1-20180825 with Open GApps pico. According to the device changes, there aren't any changes in 14.1-20180901: https://download.lineageos.org/shieldtablet/changes/ So it should be working.
[Shield Tablet Android Development] stefilie:
Thanks for the reply mate. I have downgraded to 14.1-20180825 and everything back to normal. I think I will stick to this release for now.
[Shield Tablet Android Development] just lou:
No issues here with the 9/1 or 9/8 updates.
[Shield Tablet Android Development] stefilie:
Looks like the issue is with magisk 17.0 and 17.1. All my apps in magiskhide list are crashing. Play Store inclusive. Will try to downgrade to lower version.

The last build don't even boot
[Shield Tablet Android Development] flatratte82:
It boots on my device.
[Shield Tablet Android Development] Dhalsim43:
Have you flashed it manually or used OTA ?
[Shield Tablet Android Development] faisaldante:
I am loving this ROM. My tablet is so smooth before it was laggy very happy.
[Shield Tablet Android Development] DanRub1995:
Good afternoon, please fix the lagging sensor while charging.
[Shield Tablet Android Development] Dhalsim43:
After a few tests, I've noticed determined that when I download the build from the website and flash it manually, it works well, but if I use the integrated OTA update functionality, it bootloops ?
[Shield Tablet Android Development] harryohh:
Anybody else having massive battery draining while the screen is off on the last few builds?
[Shield Tablet Android Development] groegerjo:
Did you root your tablet with Magisk or SuperSU?

I did it with Magisk and have no problem with the OTA funktion.

My device: Shield Tablet K1

ROM: LL 14.1 September 15th Update
[Shield Tablet Android Development] Dhalsim43:
I don't use Magisk and don't have root. I had the same problem of bootloop after OTA in August. At that time I didn't have the idea to download and update manually so I wiped everything and did a clean install.
[Shield Tablet Android Development] Dhalsim43:
Maybe it's related with the last version of twrp 3.2.3

Or maybe I should reflash a stock boot.img because I was previously using Magisk
[Shield Tablet Android Development] just lou:
Not here....
[Shield Tablet Android Development] Adai0:
I had this with one of my tablets too. Imho it was a hardware issue.... I also had a problem with the display a few weeks later and returned it.
[Shield Tablet Android Development] Alastor89:
[MENTION=1416222]Steel01[/MENTION] there are any news on the development for the shield tablet ? I've seen some movements on gitlab
[Shield Tablet Android Development] Steel01:
Well, I've spent the last three weeks trying to figure out why aosp P boots and lineage 16.0 doesn't. It's a struggle not to go certifiably insane atm...

Once (if...) I figure that problem out, things are in pretty decent shape, actually. Beside hardware video acceleration, which was also a problem on O, I think camera will be the only thing I have to put time into fixing.
[Shield Tablet Android Development] john_matrix:
Thank you for your work Steel! :)

I have one question, I am doing a little Magisk package to add the NVIDIA original bootanimation "systemlessly"

Everything is working properly exept the rotation. Indeed, when the tablet is in landscape mode, the bootanimation is still in portrait.

By chance, do you know if there is special setting on the NVIDIA ROM that do this rotation?

Many thanks in advance!
[Shield Tablet Android Development] Steel01:
I don't have the specific code, but I do know what triggers it. There's a kernel command line parameter that gets set by the bootloader (androidboot.orientation) and eventually gets set as a prop (ro.boot.orientation). I believe it gets set to degrees (0, 90, 180, 270).

Side note: Ew, magisk. Why not just a flashable zip to replace the animation zip?

Other side note: Which animation? The one from way back in the original portable days? If so, I really want to see that. Potentially in a couple different resolutions for some other devices I've got.
[Shield Tablet Android Development] john_matrix:
Many thanks for your precision about the trigger and prop setting.

Do you know if it will be possible for you to implement the "androidboot.orientation" trigger in a future build of your ROM?

If I have correctly understood, the prop setting is only "fixed" and will not change depending of the tablet orientation?

Before doing the package, I was just wondering what kind of flashable zip was it better to do :D

I had choosen a Systemless Magisk zip because of surviving ROM updates and not triggered the Google SafetyNet mechanism.

But maybe it's useless?

I have attached the flashable zip ;)

But it's the original Shield Tablet bootanimation (forget to precise)

Guest /multiple Account

HI,

Anyone can confirm that I can create multiple or guet account on this ROM. I need to have a second restricted account for childern.

Thanks
[Shield Tablet Android Development] multiwirth:
Yes, works
[Shield Tablet Android Development] coopmaster:
Any idea on how to fix the very low

Max volume on this rom?
[Shield Tablet Android Development] multiwirth:
The volume level should be normal for both speakers and headphones.

I'm on an older build maybe the last one is broken.

If you did a clean install, try to downgrade to an older build or do a full wipe
[Shield Tablet Android Development] Disrupthor:
Can't anyone from lineage team help out solving hw acel?
[Shield Tablet Android Development] multiwirth:
As far as I know, the lineage team is just developing the android distribution itself and some devices they owned and for anything else there are the maintainer porting the distribution to their owned device.

So even if they can help, they would need a shieldtablet aswell to help.

I don't think they can do much over the internet.

Maybe Nvidia itself can help since they have all hardware infos and sources we might need.

Maybe contacting Nvidia might be useful
[Shield Tablet Android Development] unhumanOne:
Updates - supposed to refuse them?

I installed this recently and it was working perfectly. I did enable encryption.

Got a notification that there was an update available (14.1.2) and I took it.

Seemed to install correctly, but after reboot I entered my access code, and it started to boot. Made the smiley animation and that never went away. Forced off / restart = same. Wiped cache / restart = same.

Not supposed to do this? Any way to resurrect what I had?

Thanks....
[Shield Tablet Android Development] Dhalsim43:
Try to download the last build (14.1-20180929) from the website https://download.lineageos.org/shieldtablet and install it manually in twrp. It seems like ota update process don't work on encrypted devices
[Shield Tablet Android Development] kirbymaster101:
Do I just do a wipe everything in TWRP and flash	lineage-14.1-20180929-nightly-shieldtablet-signed.zip?

Do I need anything else? planning to degoogle myself and just use Yalp store.
[Shield Tablet Android Development] unhumanOne:
Thanks for the tip - didn't work. Wiped everything completely and I'm back in action. I'll research encryption better before I re-enable it. Maybe it was just my filesystem got messed up b/c of the OTA update and maybe that's just not how to do things on these tablets when encryption is on.... Once busted, always busted?
[Shield Tablet Android Development] The_miah:
Hullo folks.

Been out of the loop since January when i quit using my tablets due to battery drain issues. Figured i might give things a go & see if there's any improvements. Did a typical OTA flash from mid-Jan update to the latest it offered, charged the battery to 100% & turned on airplane mode/put it to sleep. 7hr later it's saying i'm down to ~75% battery left with tablet idle & screen each using 1%.(60 mAh ea roughly)

That seems like a heck of a reported battery drop. are the stats off, or is the battery drain abysmal under LOS still?
[Shield Tablet Android Development] multiwirth:
Maybe a dead battery?

I have the K1 model and when turned on in IDLE while connected to wifi and still receiving telegram messages and the clock that wakes me up in the morning but it lasts for the entire week if i don´t do anything else.

It drains very quick when it´s used and that might be the screen itself since it reaches over 1000mAh of usage.

3 to 4 h sot is possible when watching netflix, youtube or the like.

If you keep in mind that this device isn´t new, the battery performance should be normal.

I´ve never ran stock, i only enabled OEM unlock in dev settings and did all the stuff to get lineage running when i got the device from ebay.
[Shield Tablet Android Development] The_miah:
Thanks for that. It's a bit off-topic i suppose, but has anyone sourced a decent replacement battery for these things yet? IIRC there was difficulty in chasing down something back when i last looked into it. maybe something more suitable has shown up since then though.
[Shield Tablet Android Development] multiwirth:
I've found this:

https://m.de.aliexpress.com/item/945908873.html

The ratings are good and as far as i can understand (reviews auto translated to german) they're all related to the shield tablet.

Some told to use the old battery controller from the original battery and it works.

Good luck
[Shield Tablet Android Development] HorizonR2:
Works like a charm, love having LineAge on my K1!
[Shield Tablet Android Development] greevedogg:
So, is GeForce NOW and gamestream working in the OFFICIAL Lineage 14.1? I browsed this thread, but couldn't find an answer to that.
[Shield Tablet Android Development] coopmaster:
Is hardware acceleration working on this build?
[Shield Tablet Android Development] Friedensfurz:
Yes, only in 15.1 it doesn't work
[Shield Tablet Android Development] harryfokker:
I want to try this on my K1. But tell me,. The Hdmi wotks?? Im on a Nougat based stock right now
[Shield Tablet Android Development] fpozar:
Yes, HDMI works on los14. I use it all the time to watch movies.
[Shield Tablet Android Development] kemoli:
Does LTE is working with this rom?
[Shield Tablet Android Development] harryfokker:
This info is real.

Works perfect, i buy It for mine, and yes i use the old controller board, just be carefull.
[Shield Tablet Android Development] Alastor89:
BTW today I tried compillng lineage-15.1 from using the gitlab kernel, vendor and device tree but It wasn't booting. The screen was black after the nvidia logo. Am I doing somthing wrong ?
[Shield Tablet Android Development] Steel01:
That's... Weird. I'll run a fresh build tonight, but it was working last I touched it. Two things off the top of my head: I haven't specifically fixed up sepolicy yet, been running permissive on all those tests. And second, bootloader. Though, 14.1, 15.1, and 16.0 all use the same bootloader version. I'll post back after I verify, though.
[Shield Tablet Android Development] Alastor89:
Thank you very much and sorry for the bother !!!
[Shield Tablet Android Development] Steel01:
Yeah, still boots for me. Hard to say what isn't right on your side. Does the last unofficial 15.1 build from the other thread boot on your device?

Side note: I've only put marginal work into the current 15.1 builds for shieldtablet. After pulling in stuff from the foster Oreo update. I know for certain camera doesn't work. Haven't done extensive testing to know if anything else is busted, though I think it should be fine.

Been trying to work on 16.0 and it 'mostly' works, but there's a graphics problem that is a pretty bad showstopper. Something is leaking file descriptors and after a while, the display will start doing weird flickering at best or just plain go black and might as well be hard locked. The mocha devs (the Xaiomi Mi Pad that's 98% a clone of this tablet) have more time to look at this than I do right now and are making some progress in tracing the issue, but no solution yet. I expect we'll get a fix eventually, then we'll be running fairly nice on P.
[Shield Tablet Android Development] Alastor89:
The builds of the other thread are running smoothly on my tablet. What I did was basically cloning the kernel/devicetree/vendor , then libstagefrighthw power sensors thermal, then I disabled dexpreopt and ran brunch. I'll retry to rebuild build after a make clobber

BTW waht's the purpose of that 4.9 kernel on gitlab ? :D
[Shield Tablet Android Development] Steel01:
Hmmm... Dunno what to say. The scripts I use to build are:

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

That repo contains the local manifests and patches. Maybe use the disable selinux one and see if it boots.

The quill / Jetson tx2 kernel is 4.4. Galen / Jetson Xavier is 4.9. In theory, I can get foster / shield TV to boot on these. With a stretch I may be able to get the shieldtablet working on them as well.
[Shield Tablet Android Development] Alastor89:
Thank you for your help, I deleted the whole lineage folder and now is downloading and building using your scripts ! Let's hope that it works !

Let's hope that the tablet could boot on 4.9 one day then :)
[Shield Tablet Android Development] wlfgng.trbr:
Hello, i have the old shield tablet (not K1) i‘m sorry but i’m not that up to date. Can i flash this after a wipe over resurrection remix 6.0.1? What steps do i have to do? Its the wifi version of the tablet. I still flash and try roms on my older nexus devices, so its not all new to me, but the shield tablet has always been a bit tricky to me. I havent updated it for a while now. Last build was mid 2016 ?

Thanks in advance for your help :)
[Shield Tablet Android Development] player594:
I've noticed recently that my K1 is getting hot while sitting idle charging. It never use to do this. I'm on the latest ver of LineageOS. I close all apps whenever Is top using it so it will charge easier and faster. It started doing this yesterday. Any ideas? I'm on stock kernel too if that helps. By the way, does anyone recommend an alternative to stock kernel?
[Shield Tablet Android Development] Alastor89:
Finally after a while I was able to compile a bootable lineage-15.1 using Gitlab [MENTION=1416222]Steel01[/MENTION] sources. I'll leave it here for who needs it. It has disabled selinux

https://www.androidfilehost.com/?fid=11410963190603843820

optionally I also tried to make a nvcamera zip since I dont like snap, but it does not seems to work, at least on my tablet, ill leave it here anyways, maybe someone can figure out what is missing https://www.androidfilehost.com/?fid=11410963190603843836 , I simply grabbed the blobs from here https://gitlab.incom.co/CM-Shield/p...mmit/b8523e5b0378ea890e662e7e09dc4cc1ebb78025

Is this a version with working hw acceleration?
[Shield Tablet Android Development] Sjamaan:
Great job man, it's working great!

[Shield Tablet Android Development] groegerjo:
I installed it - nothing to say.

Very good ROM!

HW Acceleration works (YouTube with 1080p and Spotify)
[Shield Tablet Android Development] fpozar:
Are you sure? There was a rom "recently" that had some kind of software acceleration which made it look like it was hardware acceleration doing its thing while it was actually not. I believe it was omni rom but I could be wrong.
[Shield Tablet Android Development] Steel01:
https://gitlab.incom.co/CM-Shield/a...mmit/959c1a97e9f41b2e1caf9131eb019bc3dac1b2d0

Yeah, it's all software decoding.

Camera doesn't work either. I haven't fought with the stack to get it working right again yet. I think that's the only blocker in getting 15.1 official. It's also why I'm not releasing unofficial builds. I don't particularly care about the camera myself, but as a hardware and stock feature, it has to be working for official Lineage builds.
[Shield Tablet Android Development] Alastor89:
Yeah, but overall it has been working great for doing university stuff, so tank you for keeping the repos updated. Do you think that the ongoing efforts with the kernel could help to fix the hardware acceleration?
[Shield Tablet Android Development] john_matrix:
HW acceleration is the only issue on Oreo builds right?

Is HW acceleration related to the Tegra K1?

If this is the case, why not try to use the LineageOS 15.1 K1 driver of the Nexus 9 wich one has a Tegra K1?
[Shield Tablet Android Development] Alastor89:
HW acceleration and camera for the moment.

For what concerns the last question, Nexus 9 uses open source stuffs if I'm not wrong, while on the Shield we are using the closed nvidia blobs, so the two things are not interchangeable. Maybe if the ongoing effort of using a mainline kernel goes well then we could have some benefit also from this side I think, since nvidia has contributed to noveau driver for the tegra SoC.
[Shield Tablet Android Development] just lou:
Is this going to be updated monthly now like other official LineageOS 14.1 builds?
[Shield Tablet Android Development] Steel01:
About hw accel. It's not a kernel issue, it's a problem in the closed source OMX stack. The Nexus 9 has the same problem. No K1 device has working hw acceleration since O.

And yes, official shieldtablet builds will be monthly since it's still on 14.1. The only real changes these days are the monthly security ones, so not going to be missing anything. Some time, I'll fix the camera and get 15.1 officials going. No guarantees on when, though.

Turn OFF wifi...Use older nivida games (i used 5.6 from apk mirror)...go to setting in nvidia games to login...when it shows you the various ways to login you then turn wifi ON Before pressing your login...then update to newest app in play store

Hey... I installed LOS 14.1 on my OG Shield Tablet...the one with the stylus... Everything is running great I'm very happy so far.

FYI I was having issues getting Nvidia Games working and I wanted to share what I did to get the login going.

I installed an older version and YES it prompted me to update and I wasn't able to do anything else....so I rebooted with WiFi OFF and then opened the app with WiFi OFF...

went to the setting then login and then it showed the google login which I use...I turned WiFi on then pressed the google login and boom logged in and then updated...all good
[Shield Tablet Android Development] Ikarbb:
I've been curious about this, but I've noticed on other Lineage ROMs for other devices, there is a way to adjust color, saturation, hue, and contrast. On the stock rom for this tablet, we have control of this, but not on Lineage. Has anyone been able to add this to Lineage , or is there a conflict I'm not aware of?
[Shield Tablet Android Development] Snah001:
Flashed my Original Shield yesterday and with a few hickups I got it working well.

Restored my Titanium backups of my apps and they all work just fine.

Now waiting for an official Oreo build that will work because the one posted here few posts back refused to flash probably because it is not a K1.
[Shield Tablet Android Development] MatMer1981:
Hello everyone,

so first of all a big big thumbs up for all the geniuses creating such ROM, always more powerful than the original ROM ... A big congratulations. Then I have a few questions before switching to LineageOs on my K1 tablet too.

At the moment I am under Nougat, which drains enormously the battery ...

Which of the 14.1 or the 15.1 is the most stable at this level?

Is the video history blocked at 720p on YouTube set for 15.1?

Basically which is the best of 2?

Then for updates it is also done in OTA or everything has to be done manually?

Thanking you in advance.

Sincerely.
[Shield Tablet Android Development] Steel01:
Well, as the official maintainer, I've kinda got to say the official builds are most stable. :p And officials get monthly OTA updates.

That said... On 15.1, YouTube generally plays 1080p fine. Some very high bitrate stuff might have issues, though. Since no hw accelerated codecs and all that. But since it's unofficial, there's no OTA updates. Not until I finish stuff up and release 15.1 officially. Soon(tm) in Valve time...
[Shield Tablet Android Development] Snah001:
Hope also for the original shield

[Shield Tablet Android Development] Steel01:
So, all shieldtablet ROMs are unified. Since I started officials back on 12.1. And since virtually all other custom ROMs for the device are derived from my device and kernel tree, they are too. However, I did semi recently add better checks to ensure the correct bootloader is installed. If it isn't, the image will refuse to flash. You probably just need to flash the bootloader in the OP, reboot to android, reboot back to recovery and flash 15.1.

I probably should start packaging the bootloader here too, like I am for foster. Probably not going to happen until 15.1+ officials, though.
[Shield Tablet Android Development] Snah001:
Will wait till 15.1 is official.

Hello! Sorry for the noon question, I used to flash roms on my shield a lot but I let it sit for a few years and I've gone rusty. I tried lineage but it wouldn't install in my original shield and I suspect the bootloader is the issue since people are doing it and you said that's the issue as well. Could you give me a link to the bootloader I need to flash and where I'm supposed to flash it? To boot?
