Right? I had to go into dev settings and set the animations to 0.5 just to make it somewhat smooth, it's so choppy at boot the boot animation even stutters.

Don't even get me started on using a 3rd party launcher like Nova with lenovo's 13 for this tablet, for whatever reason it puts all the icons beside the soft keys from the smart launcher bottom menu, and squishes the back/home/chooser buttons to either side. Ridiculous! But other than that I'm ok with it so far (though it didn't bring anything new I'm using really), though I have missed the little % display on the screen when I plug it in to charge it's a tiny gripe... that shows they skipped the polish.

edit:/ sorry to hear about your recurring troubles with yours :(
[Thinkpad Tablet General] xd4d3v:
These tablets are let down by their incredible slow CPU. The latest version of these, still marketed with the same name uses a Snapdragon (also a slow one) do I'm not sure if there's any benefits there.

I'm currently running the "Evolution X" GSI, it's still slow, but maybe a bit better? Can't say for sure as i haven't ran stock for a while
[Thinkpad Tablet General] GuyInDogSuit:
Does it still have the stupid UI changes that came with A13?
[Thinkpad Tablet General] xd4d3v:
The GSI? Yeah, but other UI changes specific to their rom. It gives you a certain level of customisation of things though.

If your tablet is rooted, you can try it as a DSU without making any changes to your system
[Thinkpad Tablet General] GuyInDogSuit:
Is this version Evolution X based on A13? Or previous?
[Thinkpad Tablet General] xd4d3v:
13
[Thinkpad Tablet General] GuyInDogSuit:
Perhaps Evo X on Android 12 would be a bit snappier considering Lenovo's 12 wasn't too bad.
[Thinkpad Tablet General] treysky54:
What is the last version of (stock) Android 12 for the Lenova M10 Plus 3rd Gen? Is 220805_ROW definitely Android 12? RSA is giving me 230713 but that's likely A13 and I do not want 13 on this tablet.
[Thinkpad Tablet General] amnesia1000:
Hi, first of all thanks for the tutorial, I've been wanting to change the stock A13 rom for quite some time. I installed the same rom that you have installed (LineageOS 19.1 20231017-UNOFFICIAL-arm64-bgN) and it works really well, but I have some doubts and problems.

This version of LineageOS is based on Android 12, you can install the verion 20 (Android 13). And on the other hand, this version comes with Widevine L3. Is there any way to enable the L1 or any other rom will bring it enabled? Thank you very much.
[Thinkpad Tablet General] treysky54:
I am to understand if you root and use MagiskHide, it will enable L1. May have to clear Netflix cache/data. YMMV.
[Thinkpad Tablet General] amnesia1000:
No, MagiskHide does not work, it still says L3. This question I think I already know the answer, but is there a way to enable/disable DolbyAtmos? That the rom recognizes it
[Thinkpad Tablet General] treysky54:
I don't know about Atmos, but doubt that Lineage has support bit idk.

Yeah seems L1 may not work on A12, only A13. That blows.
[Thinkpad Tablet General] amnesia1000:
I installed LineageOS 20 (A13) and it still has no L1 (with MagiskHide). I will try later a ROM with A14 but I don't think it will work.

Two ways:

* To wait for OTA update or try to get it trough VPN for other country.

* Download Lenovo Rescue and Smart Assistant and to make clean install via Rescue --> Rescue tablet.

Does anyone know how to flash my P12 Pro back to android 11? I downloaded the android 11 image from here but do I have to installed TWRP and unlock my bootloader to be able to install it? I really don't want to root unless I absolutely have to...

I downloaded the Rescue and Smart Assistant but the only image it will allow me to flash is the latest android 12L image...

[Mogul, XV6800 General] Tannerj:
Ok I have had my Mogul now just over a year and I just had to replace it due to unable to receive incoming calls out of my home area. Come to find out after I received the replacement phone, it was my account that was the problem and not the phone. Anyway this new mogul I am having a terrible time with sensitivity on the touch screen (not using the stylus). My old one was great, loved the phone and had no problem what so ever. With this one it is random, but it seems like I have to press extremely hard on the touch screen to get it to register. Is there a way to calibrate the sensitivity of the touch screen? I know about the "align screen" under settings but is not working.

any help would be greatly appreciated.

Thanks....Tannerj

No Keyboard at first boot -fix

:

This is an excellent ROM !! So thank you for these detailed instructions and links.

I just want to add my experience with a small issue of no keyboard showing up. I fixed this here: https://xdaforums.com/t/exynos5433-...oms-sm-t710-and-sm-t810.4480041/post-87316675

With that fix, this ROM runs without any hitch. I am now fully running this ROM and all apps and settings like I want.

Don't use anything above Basic in NikGapps (see my fix post). Above that one of the Gapp kept crashing and the tablet did not go through set up but stuck on "Tablet starting........"

Once Gboard is working, you can then set up and download any other keyboard you want.

BATTERY GETTING HOT

I cannot turn Off fast charging. The battery is getting quite hot on charging. The fast charging slide is stuck on the ON position.
[Galaxy Tab S2 Android Development] bmwdroid:
That's been reported already, but "fast charging" doesn't work anyway.

At least not on my device.

5.23V and max. 1.2A (getting down to 0.9A reaching full capacity)
[Galaxy Tab S2 Android Development] retiredtab:
This "fast charge" commit was introduced April 22, 2021 in 17.1.

https://github.com/universal5433/an...mmit/c70731b9a69523eaa30c1d0c12d26938e4a4c373

I never really ran 17.1 other than to solve the wifi and random reboot problems so I never tested it to see if it worked or not.

However, I don't think it ever worked in 18.1 when I looked at it and definitely not in 19.1. I'll put a note in post #1 to say it doesn't work. When I have time, I'll do some more research and see what it's supposed to do. If it is not meant for our device, I'll remove it from the code in a future update.

Let's also remember that the S2 was released in 2015 and I believe it came with a 2A 10W charger. In this post,

https://xdaforums.com/t/unofficial-...t810-aug-10-2022.4430349/page-3#post-87309527

I wrote that it took about 3 hours to charge to full from 12% battery remaining.

With a 5870mAh battery in the T810 and assuming perfect charging conditions with no loss due to heat, cable resistance, etc, then (3 hours x 2000mA = 6000mAh) is enough to charge a 5870mAh battery to 100%.

Today's definition of "fast charge" with flagship devices and > 10W chargers is probably getting 60% charge in 15 minutes.

I don't purposely feel the tablet's battery for heat, but I do notice that the ac/usb adapter does get quite warm when it's charging. However, my Apple Ipad ac/usb adpater also gets probably a little bit warmer than the Samsung ac/usb adapter. So if it happens on the stock Apple Ipad, then it likely normal for the Samsung as well.

It's not hot enough to burn your fingers when charging, but I do notice it especially when the ambient temperature is warmer too like during hot summer days. On those days, I try to charge the devices during night time when it's cooler and I never leave them charging if I have to leave the house.

One other thought is that our devices are 7 years old with a 7 year old battery. Depending on how much you have used the device, the battery could be getting to near end of life and that might explain why your battery is getting hot when charging.

I suggest you download devcheck by flar2. It's an excellent ad-free program that helps with developing and testing.

https://play.google.com/store/search?q=devcheck&c=apps&hl=en&gl=US

It has a battery tab which shows the current temperature of the battery, charging or discharging, health, voltage, etc. Maybe you can use it to monitor the battery temperature and report back what it is? If you have an external usb power/amp monitor, that would also help show you how much the device is drawing. Something like this

https://www.electroschematics.com/wp-content/uploads/2019/01/1-USB-Power-Monitor-550x550.jpg

With all the crap features that newer Android versions keep coming out with, it would help everyone if there was a built in battery lifecycle reader that showed how many cycles your battery has gone through and when your battery needs replacing (assuming manufacturers don't glue the crap out their devices).
[Galaxy Tab S2 Android Development] chappatti:
Thanks!

I realized it was getting hot because I was browsing while it was charging. If I stopped and just did reading, it cooled off. The right side of the screen was getting hot enough otherwise, and I think there is where battery is?

Overnight on silent charge it charged and is fine. I'll leave it at that.
[Galaxy Tab S2 Android Development] retiredtab:
I confirmed with ananjaser1211 that "fast charging" is not supported by the S2 devices. Our S2 devices charge at the normal rate 2A (or less) over 5V. So this code and it's menu option will be removed in the next build.

I will give more details when I write the release notes and it will also be documented in the github commit.

Fantastic and totally not count on: a smooth android 12 rom on my tab s2!! All smooth so far. Wifi download is just fine (and stable 😉). And keyboard present.

Coming from Ripees L18. Already had the right TWRP. Wiped all (except ext. storage) installed rom and NikGapps-core-arm64. After boot also magisk 25.2.

Thanks a lot!
[Galaxy Tab S2 Android Development] lojelo:
Like everyone else has said this is a nice ROM running so smooth.

Only 1 problem that I need to stop the backup option I need to disabled I don't really use it. I try to change it but it won't let me it keeps reverting back to Seedvault and I don't use it.
[Galaxy Tab S2 Android Development] pflyaz:
I fixed this by explicitly changing my backup provider to my Google account during the initial setup. I believe this is a LineageOS "feature", but I can't for the life of me understand why any backup provider needs me to enter and remember twenty words just to do a backup - it's crazy! This is a case of Lineage folks way over-engineering something that should be simple. I suggest trying to change your backup provider in settings as a first step. But I have a vague memory from an early testing cycle that I somehow got Seedvault running and I couldn't stop it. The only fix was to completely rebuild the ROM from scratch and then do the Google backup setup early before Seedvault jumped in. Good luck!
[Galaxy Tab S2 Android Development] chappatti:
I posted about this in the T710 by mistake instead of here.

The tab still does not charge to 100% outside Twrp.

OK. So in Twrp it goes to 100% and on reboot it says 100% . But then again when it discharge, it will not charge above 76%. I repeated the process, but outside Twrp it does not charge above 76%.

Funnily, if after charging in Twrp to 100%, I then use the tab I cannot get it to charge if it's above 76%. It will discharge even if I'm at say 84% and connected to the charger and not start going up from 84% but steadily discharge.

Quite unusual....
[Galaxy Tab S2 Android Development] bmwdroid:
That really peculiar.

Mine charges up to 100% in turned on condition.

Therefore I didn't test its TWRP behaviour.
[Galaxy Tab S2 Android Development] retiredtab:
My T810 was at 61% and I charged it to 100% no problem.

If you came from stock, 17.1, or 18.1 without doing a format data and clean install, I can see problems like this happening. Another possibility is that you are using an app that limits battery charging to 80% for battery management purposes. Another is something is corrupt with your file system and messing up the battery charge.

I suggest the following:

1. Backup your data.

2. Use the T810 until battery reaches 50%.

3. Boot into TWRP. Wipe system, data, dalvik/art cache, and cache partitions, then Format Data, then install this ROM ONLY. Do not install gapps, magisk, etc, just the ROM.

4. Boot into OS. Do NOT setup wifi, gps, password, lock screen, etc. Put device into airplane mode. Make sure battery shows 50%.

5. Plug in Samsung charger and high quality cable and check in 2 hours to see if battery is at 100%.
[Galaxy Tab S2 Android Development] lpedia:
@chappatti - I can confirm that my T710 has never shown this type of charging problem with any ROM, and I've had the tablet and used it pretty much daily since it was newly-released (late 2015). It still has the original battery, which is getting a little tired but is still useable. I routinely plug it in when it drops below 50%, and leave it on the charger until it's at 100%.

Is your T810's battery the original?
[Galaxy Tab S2 Android Development] chappatti:
I think there is an app or setting limiting my charge to 80%,but I bloody well dont know what it is!! This was a clean install. But I will try your suggestions.

It charges in Twrp, so it's something postboot or software related. Yes,I may have redo the format data.
[Galaxy Tab S2 Android Development] chappatti:
Yes. My battery is ogriginal- and yes years old! :)
[Galaxy Tab S2 Android Development] chappatti:
SOLVED!! Ha!!

Was a battery app I downloaded when the fast charge question was being fixed and my tab was getting hot. I forgot completely about it-- I need to upgrade storage in my brain!!!😃😃

Thought I would try a fresh install with this version so I tried booting into twrp, but it keeps booting into lineage recovery mode and not twrp recovery!

Looks like the last update removed twrp is that possible?

I wanted to root the device also via twrp seeing as magisk won't install from the app anymore.
[Galaxy Tab S2 Android Development] lpedia:
When you do a fresh install, LineageOS Setup runs on first boot - and among the options that you have to wade through in Settings is "Update recovery with ROM" (or words to that effect). If you didn't turn that off, it would have gone ahead and installed LineageOS Recovery (which is included in the ROM zip file), thus over-writing TWRP.

Always turn that option off in LOS Settings if you want to retain TWRP!

To root the device with recent Magisk versions, flash the Magisk APK from recovery. You don't have to start from a fresh install, by the way. Then boot the system, run Magisk, select Install, then "Direct install". This will patch the boot image and ask to reboot. After the reboot, the device will be rooted.
[Galaxy Tab S2 Android Development] lojelo:
The main issue I have now is not being able to use magisk to root the device so I can use quick reboot to get into download mode it's been a pain in the ass for years using the buttons to get into download mode. I have tried flashing the recovery.img but soon as it says it's flashed I reboot the device and open magisk and it says installed N//A.

I need to do a fresh install to get rid of this stupid speedvault backup option.

PS there is no option for direct install.
[Galaxy Tab S2 Android Development] lpedia:
To get TWRP back in place, try setting "Allow root debugging" in Developer options, then

adb root
adb reboot download

If that works, use Odin to flash the TWRP recovery image.

?? Not sure what you mean. You can't get rid of SeedVault completely - it comes with LOS.

To turn off installing LOS recovery on ROM update, go to Settings > Updater, touch the three dots at the top right, select Preferences, and turn off "Update recovery".

Note that you'll still have to make sure that's off next time you do a fresh install and LOS Setup runs.

Which version of Magisk did you use? And note: you must flash the APK from recovery, not install it from the booted system.
[Galaxy Tab S2 Android Development] lojelo:
Like I have said I can't get into recovery or download mode with the buttons so I can use odin i's a ballache, this is why I installed quick reboot so I could enter the recovery mode. I have been at it now for over an hour to try and get back into download mode and no matter how many times I try using the buttons it just boots back up into normal mode.

I have magisk v25.2 when I have actually got into recovery there is no option to flash Magisk ther only option I see is to apply update, I have tried using this with Magisk but it can't see the image file and I have put 3 files 1 zip 1 tar file and 1 img and it cant see the files.

I don't want to use the Speedvault backup but there is no option in stopping the service so all it keeps doing is sending me notifications all the time telling me it's failed backing up it's so annoying, I just want to disable the option and was told a fresh install might solve this problem making sure I untick that option on startup.
[Galaxy Tab S2 Android Development] lpedia:
Have you tried using adb to get into Download mode as I described earlier?

Set "Allow root debugging" in Settings > System > Developer options on the device, then "adb root" and "adb reboot download" on the PC should put the device into Download mode.

With LOS recovery you select "Apply update", then "Apply from adb", then on the PC use "adb sideload <filename>" where <filename> is the name of the file you want to flash. Don't be put off by LOS recovery saying "Signature verification failed". Just touch "Continue".

It might also give some strange error messages that aren't really errors, like "adb: failed to read command: Success" or "adb: failed to read command: No error" or "adb: failed to read command: Undefined error: 0". Ignore those.

Another method is to use "adb reboot sideload" on the PC to put the device straight into sideload mode, then "adb sideload <filename>" to flash the file. Try that if the above doesn't work.

There isn't an option to turn off SeedVault (that I know of). There is a question about recovering a previous backup, which will use SeedVault if you say yes, but saying no doesn't affect the SeedVault service.

I don't usually get the SeedVault "backup failed" nagging on my T710, but I have seen it on another device with LOS 19.1. I couldn't find a way to shut it up (without actually configuring SV backup), but I didn't try clean-flashing.
[Galaxy Tab S2 Android Development] lojelo:
I have given up with it for now mate because I can't even get the adb driver to detect the device all I keep getting is when I enter adb devices in CMD

'adb' is not recognized as an internal or external command,

operable program or batch file.

The PC is seeing the device but I don't think the correct adb drivers are installed.
[Galaxy Tab S2 Android Development] V0latyle:
The error you're describing means you aren't running command line in the right directory.

This only works if the command line directory is that of ADB Platform Tools (the folder that contains adb.exe and fastboot.exe)
[Galaxy Tab S2 Android Development] lpedia:
... or if you've added the platform-tools directory to your execution path (%PATH% on Windows or $PATH on Linux) so you don't have to keep cd'ing to the directory containing the adb and fastboot executables in order to run them. 😉
