What is the best ROM for nvidia shield k1 2020 - Shield Tablet Q&A, Help & Troubleshooting

I recently installed a Custom Rom and the truth is that it is giving me more problems than solutions.
I would like to know which is the best custom Rom to install it and that I can use the tablet 100%.
What do you recommend?
Preferably android marshmallow or higher

Which custom rom did you install?

Hi
At the moment i testing out following Roms:
Stock 5.4 (debloated by myself)
This is the latest Rom from Nvidia which has all of the oem apps and features this Tablet offers. But on the downside it has slowdowns and freezes. In my case i debloated the Rom by myself where i deleted apps and the systemapps like twitch,squid,fallout and ota or feedback for example. With this the device is barely useable with some slowdowns and freezes but way better than before.
LineageOS 14.1 by Saint2k
This is a stable,fast and secure Rom. Secure because it get almost every month a security update like on a new device and is the perfect Rom if you use it as a normal Tablet and play Games from the Playstore. On the downside Nvidia Games doesnt work and the Old Controller is just useable with the USB Cable + OTG Adapter. Also the Console Mode is buggy and some say it has a bad Batterydrain at idle what i cant comfirm yet.
AOSPExtended 5.8
This Rom is based on Android 8.1 with working Hardware Acceleration. But it has the same issues with Nvidia Games and the Controller and Consolemode. This is the more stable Version of the AOSPExtended Roms.
AOSPExtended 6.7
This Rom is based on Android 9 and the Nvidia Games App works but only when the App Signature is deaktivated with LuckyPatcher. For the GAPPS you also should use the OpenGapps Nano Pack instead of the older MindtheGapp. This is the less stable Version i also had 1-2 Restarts and 3DMarks had some Graphicissues. But apart from this it is a interesting ROM where i hope the Developer still is working on
One thing to the DRM Issues:
Every Rom also the Stock One is affected from this. Its because our Devices has Disconnected from the Widevine Service run by Google without a warning or a reason.
That means no Copyright Protected Medias like from Netflix are able to use atm.
I hope this was helpful for you and dont hesitate to ask if you have more questions.

i am also curious about this! looking for the best ROM for my k1

If you flash Magisks it has a few different modules that fix DRM so Netflix and other streaming apps work correctly. I just learned about them the other day when I was checking out some options in Magisks Manager.
As far as the best custom ROM goes I am going to have to go with ASOP 6.8. The reason being is it is the only ROM that will let my PS4 controller connect wirelessly. Also, it is the only ROM that screen casting is working for me on. However, it does not work when I use cast by swiping down on the screen and selecting it. I have to download a 3rd party app to get it to work. I found one the other day that worked perfect for allowing me to watch Cinema apk movies on my TV. I ended up factory resetting my tablet though and now I cannot remember what app it was.

Cool that means you be able to watch Netflix, Amazon, ... In Full HD ?
Because i also tried out the liboemcrypto disabler on my rootet oem tablet and i was able to start at least the netflix app but it wasn't going above 540p i would say because the Widevine CDM Securitylevel is now L3 before it was L1 with only Current HDCP Level stated as "Disconnected"
But i try out the second modul with DRM in name when the Tablet is done with charging

I tried the 5.8 aex 5.8 and it worked very well, until playing a google play game I realized that the tablet was locked and I closed the apps. Apart from that the screen mirroring does not work, it freezes the image.
Now I have installed the 14.1 , it works very well, the same game freezes, but it takes a lot longer. And this standby spends little battery, but on consumes that gives taste. And with this screen mirroring does not work with a smart tv, like stock.

What I'm looking for in a rom for my tablet is: to be able to play google play games, something demanding (like when I buy it), also be able to use screen mirroring to watch videos and movies on smart tv. And if it's possible for the battery to last.

Hi
In your case i would give the Unofficial LineageOS4.1 from Saint2k a try. Its fast, reliable, and secure because of the almost monthly security updates. Also Games from the PlayStore shouldn't be a problem. I also have a mirroring option which gave me no issues so far.

I currently have the 14.1 that you tell me installed. But screen mirroring doesn't work for me.
And demanding games, it slows down a bit or even after playing for a while, it closes my game.

Ok i tried the screen mirroring again and you are right it also crashes for me when i start it direct with the button from the dropdown menu. When i use it to cast the youtube app it works fine for me and thats the only thing i use it for atm so thats the reason i didnt notice it.
About the demanding Games i play occasionaly COD Mobile with the Tablet. Its really slow at starting because most of the time the game does updates and loads a lot of annoying ads
It just needs a bit of patience but when you actually in the match itself it runs just fine and it doesnt crash a lot for me.

for example, he played clash royale and the application closed 2 times.
Then the other day playing the game of the 7 deadly sins, it closed after 5 minutes of playing.

I recently upgraded from a 2 year old 14.1, to the latest. I found on the androidfilehost for the-saint2k sometimes had the latest on the right side, under recent files. I checked now and its updated to the latest
https://androidfilehost.com/?w=files&flid=297059
I found the kernel from BitObession
https://forum.xda-developers.com/sh.../tweaked-kernel-nvidia-shield-tablet-t3069776
K12-002 works fine and fixed my battery drain during sleep
https://androidfilehost.com/?w=files&flid=282989
I dont use screen mirroring, but i do use HDMI out for use at school and that works fine. Nvidia console is still included in this builds, and I'm glad its standard.
Now I've noticed Kernel Aduitor is no longer available in the appstore, and is over 2 years old. Is there a better kernel auditor app for changing the governors? My tablet is a e-book reader currently, I could happily downclock it to get more out of the battery.
I hope you find your solution. I wouldnt expect too much more development for this (in before lineageos16.0 becomes the bees knees for this device).

Ok sounds for me the Games running out of memory and the ROM cant handle it. You could try to change the Low Memory Killer Settings. For this you need Root Access and with the Kernel Manager App from the PlayStore you can easily change those Settings it even have some Presets as shown on the Screenshots.
It also have Settings like KMS which reduce the Memory Usage too and you can set the Read Ahead Buffer Size.
I think it may need some tinkering with those settings to find the perfect ones.

I agree with Scavenger87, I've also tested Saint2k 14.1 & 15.1, AEX 5.8 & 6.7. By far the most usable is Saint2k 14.1 the second time I've loaded it up (so far).
AEX 5.8 has outstanding deep sleep battery life but the random reboots to the OS or TWRP in the middle of doing something eventually had me loading up Saint2k 14.1, which was stable but ate battery at idle despite running the BitOb K12-002 kernel.
So I tried Saint2k 15.1 but had a lot of problems launching apps and also RR, then wiped & flashed AEX 6.7 which seemed to have even more problems with app launching. Both were quite laggy compared to LOS14.1 and AEX5.8 when the apps finally started to run.
Today I reflashed Saint2k 14.1 with BitOb K12-002 kernel and so far the device feels like is should - clean and snappy. It just finished being fully charged so I'll get an idea of sleep battery consumption over the next few days.

I would like to make an installation as clean as possible of 14.1.
What do I have to clean when I reinstall the rom from twrp?
And if I have to do a separate installation to make it work better, when should I do it? Thank you

For a complete wipe down you should go to TWRP -> WIPE -> Advanced Wipe and Wipe Everything apart of the Micro SD card for obvious reasons
Then install the newest build of the 14.1 by The-Saint2k which you can found here : https://androidfilehost.com/?fid=8889791610682953905
The Filename says its from the 6 October 2020 which wasnt revealed by The-Saint2k in the Forum and i wasnt able to test it out myself but i never had any new Problems with his ROMs.
I dont get the second question what do you mean with seperate installation ?

Some zip file that improves performance, or the operation of the tablet or rom.

Ok i don't have any expirience with such improvement files but i guess as early as possible maybe like the gapps direct after the rom.
Which files are you mean ? And did you try to test the Games without those packs ?
I mean because you facing instability issues..

My installation was only of the rom and gapps.
But there are times that they recommend you install some more package from twrp to improve the functioning of the tablet. As for example the one from aex 5.8 there is one to use fast loading (or so I understood).

[Q] Lollipop super slow at times?

Hello all,
I have installed lollipop when it came out, I unlocked the bootloader and rooted it. Then I reinstalled a bunch of apps I use (games, apps, utilities) - all from scratch to make sure that old setting and such do not interfere.
All seems to be fine (smooth, fast) - only some apps do not seem to work - however, in some cases (when for example opening Chrome) I see huge slowdowns...
Anyone else experienced this? How do I find out what is causing it? How do I fix it?
Thank you for any suggestions
Un-install Facebook. I was about to revert to Kit Kat, but I figured I would wipe and re-install. I noticed slowdown when I installed Facebook, so I nuked it and my tablet is butter smooth now.
The Facebook app destroyed lollipop performance on my Nexus 7 too. This is not a Shield issue, it's a Facebook/lollipop issue.

Wow. I had facebook installed but not even logged into, and i saw dramatic reduction in stutters and pauses when i uninstalled it.. how facebook, how?!
Thank you all. I do not use facebook. Any other possible reasons?
Applications I have installed are foldermount, adaway, titanium backup .... Could those cause this?
I also don't have Facebook installed and get some hang ups, especially when a system animation is about to occur (opening an app, going home, etc).
I'm rooted as well, with foldermount, adaway, ultimate backup (jrummys titanium), and a slew of other games and stuff. I didn't really think it would be an app issue. But maybe. I'll get rid of a few apps I have on my phone and see if I notice a difference.

Thank you. I tried that - and it makes no difference. And the problem is not just with Chrome, as I experience (more or less random) slowdowns elsewhere too. I am a bit disappointed with this whole new Lollipop experience. On one hand it is (much) smoother than Kitkat was, on the other hand I get slowdowns, incompatibilities etc. which I never experienced with Kitkat
Well I have LTE version, i am rooted with philz recovery locked bootloader and orginal kernel, i use Seeder (find it on playstore) and weekly clear cache and dalvic/art cache, have no lags and slowdowns on lollipop, if there are, they are so rare that i dont notice any more.
Did you factory rest after the update? Cause i read somewhere that already installed apps have issues with lollipop so fresh install is recommended, i also have no issues with facebook either...
And also did you try changing processor mode to max performance in Shield power control under battery menu from optimized.
I must also mention the battery times have improved alot compared to kitkat...

Sdcard can make your shield slow. My Samsung 64go uhs-1 makes my shield slow if inserted with exfat , but no problem with NTFS and a 64kb cluster size.

Thanks, I'll have to try with a re-format.
Tablet is stock, not rooted and boorloader locked. I sideloaded the lollipop OTA on my LTE version and i experience the same issue.
It flies most of the time but sometime, especially when downloading or updating apps from Play store or opening random apps like Skype or even hangouts the tablet will come to a crawl.
I think this is a lollipop issue which nvidia need to address with an update.
I have to say on 4.x the tablet was unbearably slow at times and it didnt seem to be related to any specific app. After installing lollipop fresh and clean everything is really smooth, except Chrome. When i open Chrome and start navigating i see things slow down to being unresponsive for 30-60 seconds at a time and immediately working if i close Chrome. I also have a Nexus 5 with Lollipop and no such issues there. I did install facebook so ill try removing that. Ill give the optimization thread a peak too and see if that works.
Im impressed overall with the Shield tablet, but its a blemish that general web browsing is faster on CM11 on my Kindle Fire HD (original). Maybe Nvidia will come out with a fix, or someone here will pin point the exact cause.

For me, web browsing in general has been a pain, many browsers don't seem to work well on our hardware. They all feel somewhat sluggish. And flash has been very picky for me... I think it is finally dying, haha.
Get rid of Facebook if you have it and try this for chrome

Lastpass?
Do you happen to use LastPass? I found that, upon a fresh install, everything worked great until I installed LastPass. The way that they set up autofill in lollipop seems to hang up the whole system. When I disabled "Enable fill service" in the settings, the tablet was blazing fast again.
After playing with it, I found that I still got decent performance while still being able to leverage the best part of the app by enabling the fill service and disabling the helper and scanning for password fields.
A little app called cache cleaner can do wonders? and a simple reboot also helps a lot.
Btw. im using Yandex Browser for now untill BoatHD gets the lollipop update and it works really well on the Shield with 5.0

Extremely slow and laggy

So I got my Nvidia Shield a while back. The first thing I did when getting it was installing all the updates. Eventually after the final update was installed, I did a full factory reset of the device.
I have hardly any apps installed besides the essential Google applications, but my Nvidia Shield still feels remarkably slow. Chrome is practically unusable, and switching between apps is not a pleasant experience at all. That said, benchmarks and games perform wonderfully, which has me a bit puzzled. There doesnt seem to be any problems with memory leaks as there is plenty of RAM available. I do tend to restart it quite often just to see if it makes a difference, but I doesnt really feel like it has much of an impact.
Does anyone here have similar issues at all? I have worked with Android quite a bit and never have I experienced a system run Android so much worse than you would expect given the hardware specifications. My Nexus 10 feels a lot more snappy in general use.
Thanks for any help
All I can say is that I have a similar experience to you, although I have quite a lot of applications installed. I don't have any solutions for you, only to wait and hope that nvidia optimises the software for the hardware in the next update (Android 5.1 hopefully)
It's up to you, but I will recommend you to try this:
1) Unlock bootloader and Root (If you haven't).
2) Use CWM in this thread as custom recovery, I know TWRP is fancier but has some issues while flashing and wiping stuff, tending to not cleanly install things.
3) Try @BitOBSessiOn custom CM12 ROM here.
4) As stated there, avoid CM gapps, we don't know why but they are culprit of making the system lag A LOT making it almost unusable as you posted, specially if you frequently use Facebook and Chrome. Instead use the minimal gapps posted there.
5) Really important step: Activate Developer Options and disable all animations, lollipop men leak resides on a function called when the system draws them, so the only temporal fix for this is disabling them, after that, reboot and kill any bloatware app on options > apps (G+, FB, Messenger, Vine, Chrome, etc)
6) Profit
I've had this problem too.
I just turned off battery saver. It got too low, automatically turned on and I didn't realize but when I turned it off, it got way faster.

The Lollipop memleak bug is pretty easy to detect though and that's not what's causing the performance issue on the Shield Tablet. At least not in my case. While I would normally be the first to unlock my bootloader and port CM to my new device, I would want to keep my tablet stock.
Im glad to know I'm not the only one experiencing issues so Im going to assume that there's nothing specifically wrong with my device in particular. I guess Ill give Nvidia one more chance to rectify performance issues with their next update, otherwise I'm selling the tablet and buying a Nexus 9 or something else.
I have the same experience. I have flashed the latest recovery image, unlocked and rooted. I have disabled apps I don't need and does not have a lot of apps installed. It is unbelievable slow. Like stated above Chrome is almost useless and switching apps is painful. I am using my Nexus 10 too, the Shield tablet will collect dust until there is a fix released.
If I have the time I will try flashing CM12 but I rather stay stock.
You should give it a shot...
Chrome lag totally solved. Most Nvidia apps work. Only deal breaker is the controller, but a ps3 controller can be paired via BT using sixaxis app.

This has almost convinced me to switch to cm12.
If it just werent for the loss of Dabbler, some other Nvidia apps and the fact that I have a looooot of apps installed...
Not worried about gamepad, because I use an ipega 9023.
I may have found the holy grail of slow laggy freezy hell! https://play.google.com/store/apps/details?id=com.jrummy.apps.memory.manager under tasks go to 3 dot menu at top right choose minfree manager pick the top silder and max it out.

I don't know why but it won't keep the settings after boot no matter what I do but I can live with it now and don't fantasize about smashing it with a rock anymore.
I should mention short of non-stock Nvidia roms I tried EVERYTHING twice! This just works for 3 days now perfectly. I actually might even trust it in a week for actual work applications. My poor old Nexus 7 gen one was totally owning the Shield except for game until now.
I have a LTE USA model running rooted 4.4 Kit Kat. I would guess this will work with 5 as well.

Root your tab. Do a nandroid backup, backup your apps with titanium backup, flash cm or team eos rom (gotta plug my stuff, restore your apps with titanium. If you don't like it, restore your nandroid and you're back like nothing ever happened.

Dabbler works fine on CM. It's on the Play Store.

And GRID also works fine. The only deal breakers (and the ones every dev is working hard to make em work on AOSP) are console mode and the controller wireless pairing.

That's contradictory. I have a really tiny LMK value for foreground apps (foreground= 8mb, Visible=16, secondary=32, hidden=64, content provider=96, empty=128 ) so apps in the foreground are killed only if system goes under 8mb of free ram, and have no lag, but I'm on CM12.1. So I really don't know how this is working but I'm glad for you. Although it may drain your battery faster BC android is killing apps as soon as they go to the foreground to keep that amount of free ram and is using more CPU cycles to load them back when you need them again, that's what I get. But anyone with more knowledge maybe could guide us why this is working???
Interesting, it's working but I didn't even try any other variables. I will try your settings and get back. Needless to say battery life is next after usability.

Ok tried your suggestion verbatim. It immediately was back in useless mode as I have been calling it. Without a reboot it took me at least 15min to get back to here. Still could not type so minmanged back to previous settings and its running. Weird.
My test would have been run Facebook, chrome & this app with poweramp music. Never got halfway before it got all James May on me. Are we running the same tablet? Any thoughts on why we could have opposed settings and get different successful results.
---------- Post added at 07:02 AM ---------- Previous post was at 07:01 AM ----------
Also when it slows down it gets warmer the settings I'm using leave it pretty cool in comparison.
I'm on stock 5.0.1, 32gb SD + internal memory almost full. I experience some lag mainly with chrome and switching app. Yestetday I tried to set the power saver to "max performance" and the everything seems much smoother..
Make sure you SD cards are formatted with NTFS. exFAT is fine for 32gb, but if you have a 64GB or higher, the card needs to be formatted in a PC using NTFS...
Don't ever let your main ram storage memory get below 500meg.
If somehow you run out of memory,, let's say sub 10megs then all manner of weird things begin to happen including reboots and app crashing. You can jam that external sd1 card full however.
I reset mine several times and tried everything I saw in these threads about the lagginess and stuff.
In the end, I found the solution. I returned the NST and exchanged it for a new iPad Mini 2 32gb Retina Screen... No really.
I love Android on the phone, but it just seems that the tablet arena isn't anywhere near as far along and sorted out yet. Buggy, almost too many options, so you wonder how much love each model gets from the manufacturer, etc... I hate to have a new tablet for $300, and the only way to get it to run the way it was supposed to run out of the box, is to void the warranty, root and install a custom ROM on it, and give up some features in the process.
I like ROMs for things that they do above and beyond the stock experience. I don't feel that I should pay that much for a device and have a ROM be a requirement just to get it to run decently...
So, for my tablet needs, I had to go to the dark side. Good luck!
I will still rock my Note 4 and don't see myself going to Apple for my phone needs any time soon, but for a general purpose tablet for Netflix, email, browsing and basic games... I agonized for hours over this but in the end I just pulled the trigger and exchanged it.

Is there any good modern ROMs you guys would recommend?

Running Viper ROM and it's only on Android 4.2.2. A lot of apps I can't use because it's not supported, and now the latest Google Play Services has totally broken my phone
Any good ROMs to recommend running a newer version of Android? I need good GPS as I use my phone for navigation a lot
Update to this post: Running jrior's CM 12 from original android dev forum... working pretty well. Performance is a lot faster than Viper 4.2.2 actually. Some apps don't work well at all though, haven't figured out exactly why. Occasionally camera doesn't connect and just shows black too, fixed by a restart. Overall, not bad and gives me the ability to use modern apps on my phone again.

How did you get to stabilize it. For me the rom is restarting every few minutes. Sometimes it restarts when I try to install any apk(either from play store or side load).

Are there any usable ROMs?

Are there any ROMs that work well/ respond to touch quickly?
I recently pulled out my old tf201 to try to start using it again. I was able to get the last version of HairyBean working.. But it is really really slow. Like I'll click a button and maybe 30 seconds later it will respond (or tell me the app isn't responding). I mostly use it for my kids to watch shows. Once the show starts it works great, but just navigating the menus and apps to get to the shows can be excruciating. Also, I know thisdevice has WiFi issues just due to the all metal construction, but I feel like the WiFi is even slower than what it used to be when I actually used this 5 years ago or so.
I flashed a couple of other ROMs and either had a lot of bugs, or couldn't get root, or something. Does anyone have any recommendation for a ROM that works well and is actually usable? Thanks!
Anyone??!! I recently put kashmellow (tduros android M). Gapps no longer works so I didn't install that. Many people say its fast w/no gapps. But mine is barely usable. So slow. What the heck happened to these devices? Thing used to be a beast! Believe it came with ICS
I use KatKiss timduru site and xda thread, it is Android 4.4.4 ROM and it is quite fast an somewhat usable. I also have old Google Play Services 10.5.42 that mostly do not crash so even Play store works. However many new apps either cannot be installed or crash because of missing NEON support, sometimes older apk versions work. Basically I keep it for lot of old stuff that still works but don't update anything (or keep Titanium backup of apk+data and often restore back to old version when newer one crashes or needs newer play services).

It seems that contributing to LOS building ROM is not anymore tolerated, this post is deleted.
Maybe @Scavenger87 wants to take a look here ;-)
I guess it's better to have an own dedicated thread.
Thanks for setting up a distinct thread. Things were getting confusing!

Hey John great idea with opening a new Thread because i also think its really confusing already
john_matrix said:
@Scavenger87: Steel01 advised to let 15.1 (I think he is right because it's too old and because lot of changes have been done between 15.1-16.0)
Also have found this during LOS 16.0 debugging and when application is crashing:
Starting from Android 9, LMK can be implemented in userspace and needs new optimization settings:
Low Memory Killer Daemon | Android Open Source Project
source.android.com
Will see if this new userspace LMKD can be tuned.
@Trevor_g: can't say... I don't have an Nvidia controller to test.
Click to expand...
Click to collapse
Ok yeah i think he's right for multiple reasons
- 15.1 had still unsolved issues aside of broken omx like the crashing nv games app and not working screen mirroring which is working so far on 16.0
- 16.0 is Android 9.0 based which is the same as the actual Software for the Shield TV. That means there is maybe a chance they can use some Codes or even Apps like the Shield Accessories to makes things like the First Controller working again over WIFI.
I even found a lot Nvidia OEM Apps here on APK Mirror : https://www.apkmirror.com/apk/nvidia/
I think i start testing around with those apks as soon i installed the lasted 16.0 build
@Trevor_g
For your question i have to check that again on 16.0 with the old Controller but i think its still only working over a OTG Adapter.
Like i mentioned above maybe the Shield TV Accessories App is working.

Someone even mentioned this Linux Driver for the Controller
But to be honest dont suspect too much on lets say all this bonus functions because first the LOS Team have to work on the base build to make it stable and running right
Ok i installed the latest build (4/1/21) yesterday on my LTE Tablet over sideload because i had no extra SD Card to format it to FAT32 and with the new TWRP 3.5-9.0.
I installed also the Pico Gapps and then TWRP said when i was about to Restart that there's now OS installed.
But thats seems to be a bug with TWRP itself because after the restart there was the LineageOS screen waiting for me and after a freeze for about a minute or two i was able to complete my installation.
After this i now can say its the most stable LOS 9.0 Rom so far !
It has very less apps crashing so far i only had to start them twice sometimes and also the hw acceleration working now most of its time at Chrome and on the Youtube App.
I can really see there has going again a lot of work into this Rom and its really a pleasure now to see how it get more stable everytime.
Big thanks to @Steel01, @npjohnson, the whole LineageOS Team and of course to @john_matrix
Btw @john_matrix did you change anything on the partitions you mentioned earlier on this build ?
@Trevor_g
I did a short test yesterday with the controller and as suspected it doesnt recognize by the tablet. I soon test out those Android 9.0 based Accessories App from the Shield TV
Thank you for the rom
Can I just flash this over Lineage 14.1 or do I need a factory wipe?
Did anybody test gamepass streaming yet?

Yes you have to wipe the device first in TWRP to install this rom.
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.
If you use Sideload it might says in the Shutdown Menu :
No OS installed !
Which is a bug in my opinion of the new TWRP 3.5-9.0 Package but please use this Version of TWRP in any case that the basement of the installation is everywhere the same !
This is IMHO the way to install a Rom in a clean way and helps tracking down bugs better when everyone used the same methodes.
@john_matrix
I installed the Rom today on a K1 16GB with the methode i described above and did it with my regular SDCard i use in all my Tablets. In comparsion to installing over sideload it didnt get the No OS installed! message at TWRP and i didnt had that 1 minute freeze at begin of the install-wizzard after the LOS Logo.
Also the Rom seems to be same stable as the one on the 32GB model.
But i have to test it a bit more side by side to make valid statements
Also Nvidia Games working nice as you can see on the Screenshots
Hi guys, so, long story short i got scammed on a dutch advertising portal and ended up with one of them shield tablets which were recalled a few years ago. Yep, those with the defective battery that may burst in flame one day
Anyways, i figured that since it hasnt happened until now, i might just be lucky and give it a shot.
Its great to see that there is still some active development of this device! flashed this rom and i gotta say im positively surprised. Its running nice and smooth and even though it crashed on me a few times after the first boot, but a few reboots later and its running like a charm! i didnt bother with gapps, root or anything yet though. really great job devs!

My tablet was completely wiped with no OS so I just pushed the ROM, pico gapps, and magisk over USB onto internal storage with MTP/TWRP. Flashed it all from there and it worked fine. No issues or errors. I don't think it's at all necessary to sideload to use an external SD.

In this Thread beginning from here i share my informations so far about the two type of batteries and changing them out if you interested:
Finding Replacement Battery in 2017?
Anybody know where to find a battery that will fit in the Shield Tablet? I know there are several threads online (here on xda, on GeForce forums, and other places) that discuss replacing the shield tablet battery and a few different part numbers...

I did these two type installation because @john_matrix mentioned to use a SD Card which is formated with FAT32 instead of exFAT. I didnt had one lying around so i used sideload this time.
Thank you everyone and Scavenger87 for your feedback! ;-)
About stability, I guess the culprit is the fact I have played with the new userspace LMK but for me it's not stable enough to be used as daily.
For example, Youtube often continue to play videos greeny and blocky and this is annoying
I will try to fine tune the best settings for LMK.
About battery, I have changed mine too with this one:
https://fr.aliexpress.com/item/32807531204.html
It works good but require to use the board of the original battery.
Seems to be going well so far for me, battery life seems good and for the general use I have had time to do it's worked well.
One crash that caused a reboot, after testing the hdmi output the tablet rebooted when I unplugged the hdmi cable from the tablet.

Ok that means there is still some kind of memory leak problem with our tablets or is the memory managment on android 9 and higher not really suited for our low ram devices ?
I also read something about drawbacks with the in-kernel LMK as you can see here :
Drawbacks of in-kernel LMK driver
Android deprecates the LMK driver due to a number of issues, including:
Low-RAM devices had to be tuned aggressively, and even then would perform poorly on workloads with large file-backed active pagecache. The poor performance resulted in thrashing and no kills.
The LMK kernel driver relied on free-memory limits, with no scaling based on the memory pressure.
Because of the rigidity of the design, partners often customized the driver so that it would work on their devices.
The LMK driver hooked into the slab shrinker API, which wasn't designed for heavy operations such as searching for targets and killing them, which slowed down the vmscan process.
Is the zRam function now activated by standart on Android 9 and higher to compress amount memory is needed ?
I try to stresstest it today with a website that have a lot pictures sadly i cant use instagram anymore because you need a account now
Shield Tablet can't be considered as a "low ram device" as Google defined them with up to 512MB (Android Go?)
Android Performance Optimization | Android Open Source Project
source.android.com
I also have devices with 2GB that are currently performing Lineage 17.1 very well (Sony Z3C and Nexus 4)
I don't know if zRAM is activated by default in Android but you still have the choice to activate it or no (in the kernel or in the fstab.
Additionnally, I don't know what is the policy to activate zRAM (my Mi9 have 6GB RAM and have zRAM activated by Xiaomi so...)
Another thing about zRAM is there are lot and lot of options you can activate such as compression, lz4, clear caching, etc... depending of your needs and I am not skilled enough to say exactly what will be the consequences of these options (but it cost nothing to try).
You also have to keep in mind that zRAM will consume more CPU times (as KSM).
Similarly, you can fine tune the CPU governor and IO scheduling (often I see CFQ by default but on the other way I have saw that Noop and Deadline gives best results).
Feel free to share your experience and if you have other ideas on what you would like to integrate in this ROM (as the best possible).
You are right to stress test the OS, you can also debug the memory and the weight attributed on the processes.
Ok but 2GB is really not much these day also this article from android source is really old i think i read there something about kitkat or so
But your right i also was suprised to see that my xperia z3 compact i have lying around is able to run lineageos 17.1 and even is supported by the LOS Team
Which leads me to the question is the memory managment on the Qualcomm SOC so much better ? Ok the Ram there is on the SOC itself instead of external like on our Tegra based devices.
I think i install tonight Triodexes 15.1 with zram to compare the effect it has.
I also noticed the hw acceleration crashes the most on the firefox browser like i told in the 15.1 Thread you can start one video and it runs if you leave everything untouched but your not able to start a second one even with autoplay.
Btw about the LMK i know its maybe a dumb question but did you try the original settings from the Oem Rom ?
Edit : The original values in minfree are: 18432,23040,27648,32256,36864,46080
And zRam is already activated on the LOS 16.0 Build with 511MB same like the oem rom

Thanks SO much for looking into this for me! You mentioned later that the controller wasn't recognized by the tablet, however I'm also curious if the Accessories app from the ShieldTV might help. Thanks again, in advance!
Fwiw, there's a bunch of framework patches needed for the wifi direct controller to work. I've yet to get them all straight. Haven't had that working since cm-12.1. See the incomplete set for 16.0 here:
https://review.lineageos.org/q/topic:shield-blake-p
That's on top of:
https://review.lineageos.org/q/topic:nvidia-shieldtech-p
And there's no nvidia pairing app that works with a touch interface. It's a mess atm. I did get blake to pair to foster on 15.1, but only while the pairing wizard was open. As soon as I hit back to close it, the autonomous group goes down and the connection is lost. And now, it's close to impossible since nvidia didn't release the nvwifi prebuilt jar to link against. And the one from O doesn't work on P.
Hi @Steel01
Thank you for keeping us updated on your work with the controller and also for your work for this device in general
I already tought its not easy to bring wifi support back for the old controller but i think also there is no high priority since the second gen is working fine over bluetooth and they already cheap to buy used.
Other than this the rom is suprisingly good running for this early stage and most of the stuff is working
Is there something that needs special attention for testing at the moment to help you developing ?
Like i mentioned in a other Thread i have every generation of the Shield Tablet and Controller. Only on my LTE Modell the SIM Card Reader is unfixable broken
But i still hunting for a fully working device.

Well i dont know if its really needed to wipe the internal storage but i think by the reason we testing here a new Rom in a really early stage we should give it the cleanest basement as possible to exclude problems that might caused by left over data that interference with the Rom
