Nice you are back. I'm using your lineage-14.1-20210102-UNOFFICIAL-santos10wifi so far, with no issue since a week.

Please update post #1, thanks

Beta 6 is here

Hello everyone, Beta 6 is here ! LOS has been updated and microphone should finally be fixed. Wifi should also work for everybody. I updated some code in the kernel and adjusted LMK and ZRAM. The device should be more stable when using Gapps and/or use memory hungry apps/games. You may experience some slowdowns however (there's no magic here, the device still has 900MB of memory...).

I'll try to answer your private messages during the week ;-)

Have a nice day and happy flashing !

is that normal, that this tablet is so slow? It was slow with stock rom, but with that its a little bit faster, but still slow

I'm getting error 7 in twrp when I try to flash the wifi zip over the top of the 20210102 build.

Edit- apparently it just was an issue with the rom zip being in downloads instead of root of sd card.

Glad that you're available and keeping this up to date! I hope this fixes the Bluetooth earphone mic issue. I'll write here when there are any issues! By the way, I hope this also fixed the issue with the launcher, it has like black at the top and bottom which is annoying, I have to reinstall the launcher (first installing a third party launcher, then uninstalling the stock one and then reinstalling it again and putting it back as a system app) so the dark shade would go away. I hope this is fixed as well!

I diirty flashed it over the last build and it's working great so far. The tablet is still slow, but I guess that's just because of the low RAM.
Thanks a lot, this ROM is the only reason I still have this tablet running!

@nels83 2 bugs found, since you're active (thank God), I hope you can look into these:

These bugs aren't new, but since you're here I will put it here so hopefully you can fix them.

1. Launcher Bug:
Whenever I flash this rom, this new version and the 2019 one (I don't know about the other old ones), the launcher always has dark black shade at the top and the bottom like this picture:

This isn't edited! It's really like that. The only way fixing it is when I install a third-party launcher like Nova, then uninstalling this stock launcher with root and then installing it again with APKMirror and moving it back to system, then the black shades are gone. I hope you can fix this, it's pretty annoying and disturbing!

2. Errors/Notices from ADB:
When uninstalling system apps with adb, I get these:

These warnings look serious and like it says may be the reason of wasting memory and etc, I hope you can fix these as well. I checked it isn't from my adb software thing! I tried uninstalling something from my phone with adb and these errors didn't show up, so it's from the tab's rom. Probably some wrong codings and etc, I hope you can look into this!

@nels83 please let me know I hope you can fix these, and if you will let me know so I would be happy that this is going to be fixed soon!! Thanks for all your work

Guys,
My tab is alive again, thanks to this Rom and the dev.
However, I mainly use my tab for music and the sound does not seems to be very good.
Is there a solution or a mod to boost a little bit audio? this is quite importante for me.
Thans in advance for your help

I did install VIPER4ANDROID FX, but I cannot configure it as I used to in earlier android versions. My goal is too boost volume. Any help welcome.

one thing i notice when i use this rom is that the settings app takes exceptionally long to load. can this be looked into?

Hi,

I have been using the 20210102 build without issues, and I am trying the beta6.

Everything works fine except one app that I'm trying to use (SkyDemon). The displayed elements are huge, as if it were "scaled" from a smartphone screen. The app "DisplayInfo" reports a density of 680dpi. I don't know exactly where the problem can come from (build.prop seems fine and every other app/system looks good). DisplayInfo reported 150dpi on a stock-based ROM and Skydemon display was fine then (but it wouldn't run after the first "disclaimer" screen...). Any ideas?

Anyways, thank you for sharing your work!

Hi,
It seems that magisk does not work with beta 6.
I tried a clean install as well.
Thanks a lot @nels83 for your amazing work

Yes Magisk doesn't work, you need to use the LineageOS root plugin which is under "How to root". Magisk isn't known to be stable with all devices, therefore it's better to use what it's supported.

@nels83 is it possible to add fixes to the kernel for the magisk
takes alot of time to open the magisk app

Beta 7

Hi everyone,

I updated the ROM with the patch from @ddudek77 (thanks!) which should fix Magisk. I also updated LOS to security patch level April 05 2021.

@SerjSX I didn't look into the launcher problem yet but the warnings are "normal". The old binaries need text relocations, even though they are deprecated.

Tablet is slow because memory is low and the low memory killer needs work. Since new android versions use another memory handler, I started looking at it. Don't expect something working in the near future but I'd really like to update this rom ;-)

Thanks, magisk 22.1 is working properly now

Would you be interested in adding some more tweaks?

In this post there are some optimizations for build.prop:

https://xdaforums.com/t/rom-gt-p52xx-unofficial-7-1-2-lineageos-14-1.3587761/page-90#post-80230717

Personally I only use low_ram and dalvik.vm.isa.x86.features


For low memory I add a swap like in this tutorial:

https://xdaforums.com/t/swap-for-samsung-galaxy-tab-3-10-1-gt-p5210.3421538/

But I create it on /data (have enough space and feel safer if /system remains read only)

Thanks, i did that all and now the tablet is useable.
