Guys, I tried reflashing, everything. The only thing that fixed this for me is in my previous post, but obviously you don't want to give it a shot. After I attempted to update play store and a reboot there were two ps icons in my app drawer, one greyed out and the other active..
[Thinkpad Tablet Android Development] trentalar:
I tried it with an apk, but the problem is still the same.

Then I tried it with another open gapps (pico -20200530) and now it seems to be ok.
[Thinkpad Tablet Android Development] Googole:
I tried [MENTION=4373016]Tirofog[/MENTION]'s possible solution but the error message still popped up.

But then, I tried [MENTION=1334154]Tentralar's[/MENTION] possible solution but if I open Google Play Store, I can use it for a while but it closes automatically.

---------- Post added at 02:13 PM ---------- Previous post was at 02:09 PM ----------

If you want to download apps, download the apk's online until this problem is solved

A idea came up in my head: Disabling Google Play.

I disabled Google Play and now the error message is gone.

I've installed Aptoide as a app store for my tablet
[Thinkpad Tablet Android Development] ensmed:
I installed 0607 on my TB-X704F with 0530 gapps, the only issue i have is back cam not working and app closes with the message "server died, closing the app":laugh:

If someone has a definitive solution for the "Google Play Keeps Stopping" error message popping up all the time or found it, please post the solution here
[Thinkpad Tablet Android Development] michaeldingbin:
I downloaded a latest google store apk, and install it via "File". The error message is then gone.

No problems to update and install apps via google store after that.

Backup and restore of original version (factory reset)

Hello everyone,

although I am not afraid of my linux, I am a pretty much a complete newbie to flashing ROMs.

I don't mind getting a "RTFM" with a hint which one. So much for this being my first post.

I do have 2 devices of this same kind and I already did install LineageOS (I missed installing the gapps, will do that again now) with the files from this thread and mostly the description from

https://xdaforums.com/thinkpad-tablet/development/lineageos-16-0-lenovo-tab4-10-plus-t3923394

However, I seem to have failed at creating the backup of the stock (/original/factory??) version. Possibly because I let the device format the sdcard. I did not touch the second device, so I still have a clean one for the another round. But this time I ask beforehand:

How can I backup the stock version and how can I restore this version? Or is this not possible at all? Or can I skip the backup, since there is an official source for it already...

Files in my desktops downloads folder:

me.twrp.twrpapp-26.apk

lineage-17.1-20200607_140120-UNOFFICIAL-TBX704.zip

open_gapps-arm64-10.0-stock-20200609.zip

[MENTION=8899681]rock_shoxit[/MENTION] SkyGo only works with the Version 13.1.1 and Mgisk Hide. Magisk must be hidden too.

Just download the SkyGo App in this Version and don't update it via Playstore and you can watch.

HF!
[Thinkpad Tablet Android Development] Tschumi:
I upgraded from lineage 16, flashing directly the new version and the nano gapps. Everything is perfect, everything works.
[Thinkpad Tablet Android Development] rock_shoxit:
I'll try, thanks!
[Thinkpad Tablet Android Development] Nuclear Blast:
Have you done any wipes during flashing?
[Thinkpad Tablet Android Development] YesMan:
[MENTION=9969624]Googole[/MENTION] [MENTION=10877209]michaeldingbin[/MENTION]

Wich one is the latest version of the "Google playstore"?

I only can finde the 20.4.18 and that's the Version i have running. With the message.

I just found the 20.5.14 at akpmirror. Problem is fixed now. [emoji106]
[Thinkpad Tablet Android Development] Nuclear Blast:
I upgraded from LineageOS 16.0 to LineageOS 17.1 (2020.06.07 build) by flashing in TWRP the new version + pico gapps from Opengapps project.

Everything is OK, IMEI is exist.
[Thinkpad Tablet Android Development] Tschumi:
Yes, but only dalvik/cache after installing the rom and gapps. Didn't touch data or system.
[Thinkpad Tablet Android Development] Nuclear Blast:
Done in the same way. Thanx for your reply
[Thinkpad Tablet Android Development] tboege:
Compass now working after upgrade form LO 16 to 17.1

I upgraded directly from LineageOS 16 to Lineage17.1, applied opengapps nano amd64. Finally, I wiped dalvik/cache.

It seemes that everything works, but GPS takes a while to find posision.

The only problem is, that compass is not working - an app claimss that "Your device doesn't have magnetometer sensor". I am not shure it ever worked before.
[Thinkpad Tablet Android Development] Tirofog:
With Dolby a non runner and Viper not really that effective, I set about editing the mixer_paths file to increase speaker/headphone volume. I was able to copy the file from /system/vendor/etc, edit the relevant values and, in TWRP, replace the original file with the modded version. The result is a nice volume gain which is all I wanted in the first place.

Generally, in app scrolling and responsiveness etc are much improved over Los16, but portrait home screen transitions are laggy and stutter when swiping, on every build I've tried. Anybody else experience this?? Before flashing I went back to stock firmware to eliminate any possible cause, but it's always the same.
[Thinkpad Tablet Android Development] ericDraven77:
Can you provide the exact steps and Values you did?

The speaker Volume is something I would want to change too. It is much to silent for me.

Thanks in Advance!

Maybe then this could be implemented in the rom?!
[Thinkpad Tablet Android Development] Tirofog:
1. In TWRP mount system, then open file manager.

2. Copy downloaded file from sdcard and paste in /system/system/vendor/etc. (original file will now show with .bak extension, delete if you want).

3. Set file permissions chmod 644 and reboot.

That's it!

Always a good idea to backup first. The relevant values in the file are for 'RX1 Digital Volume' and 'RX2 Digital Volume' near the top of the <ctl name list. The stock values are 84, which I increased to 95. You can edit these as you wish, but setting them too high could damage the speakers, so at your own risk.

How is home screen swiping for you, any lag?
[Thinkpad Tablet Android Development] ericDraven77:
Do you mean now or after your patch?

For now I don't have any problems with lags. Neither in the home screen nor in any apps.
[Thinkpad Tablet Android Development] Tirofog:
I've always had a lag but looks like it's caused by google restoring of old wallpaper from backup, sorted now ??

Hope you got your volume increased ?

Dolby works people just don't flash it properly. Works on 16.1 and 17.1

---------- Post added at 12:41 PM ---------- Previous post was at 12:40 PM ----------

Need instructions just ask
[Thinkpad Tablet Android Development] Tirofog:
Yes please :good:
[Thinkpad Tablet Android Development] kirknado18:
Thing is most people are flashing it with magisk and it doesn't work right. I ran in to this problem before and it drove me nuts for months. The problem is people are flashing Dolby with a canary debug version of magisk and its not going to work no matter how many times you try. You need to flash a stable version of magisk 20.4 is what I'm using. Open magisk manager go to settings and where it says update channel check to see its set to stable and then disable updates to it. This will ensure there's no updates to it. Now flash audio modification library don't reboot then flash audio compatibility patch don't reboot now flash Dolby. Reboot your device and boom working Dolby. Let me know if this guide works.

---------- Post added at 02:17 AM ---------- Previous post was at 02:10 AM ----------

The audio compatibility settings for some tablets may differ slightly so try different combos if it doesn't work. I'm using a Lenovo 10 4 plus running lineage 17.1 with magisk 20.4.
[Thinkpad Tablet Android Development] Tirofog:
Thanks for this, but it's driving me nuts now.. can you clarify a few things:

Which dolby module, can you share pls?

Selinux state needs to be permissive?

Where are the audio compatibility settings found?
[Thinkpad Tablet Android Development] kirknado18:
How many instructions do you need lol. Dolby version 6.8, audio modification library 3.5, audio compatibility patch 1.76. Please don't ask me where to get these do that yourself

---------- Post added at 02:17 PM ---------- Previous post was at 02:14 PM ----------

There are 4versions of Dolby for lineage 17.1 android 10 is. 6.7, 6.8, 7.0 and 7.2 last two are mmt ex
[Thinkpad Tablet Android Development] MiSSigNNo:
Finally I've been able to estabilize the ROM with root

Upgraded from May 25th to latest june build but it started a boot loop

Uninstalled Magisk and reinstalled the latest june build and it went right but Google Play Store kept failing

Installed the 21th June Gapps build (25th June provoked a failure in Lineage's Trebuchet Launcher)

And finally I installed Magisk 20.4 sucessfully.

So far so good. No more errors poping.
[Thinkpad Tablet Android Development] kirknado18:
You do have a new bug that I found you can't disable org.lineageos.snap camera its greyed out so can't remove from app tray. Magisk debloater doesn't work either as camera isn't listed under system apps or system apps priv its no where to be found. But yet there it is under apps in setting and app tray.. Previous update you could disable camera now you can't. Nothing personal but snap camera sucks guys I use gcam.. Now I have 2 cameras 1 I can't remove or disable isn't this nice. I want this fixed its very irritating. You can't even remove it from twrp either system camera not there either so what's going on CODEWORX. Please provide a new update that allows you to disable or remove snap camera this new 20200607 update messed it up for me.

please fix snap camera issue i would like to disable and remove again asap thanks.

---------- Post added at 03:57 PM ---------- Previous post was at 03:46 PM ----------

I also tried terminal emulator pm uninstall org.lineages.snap. Failure (failed to delete). Something going on here is the camera there or not if yes why can't it be disabled or removed then. Please explain what's going on here. Used to work these previous updates broke it somehow
[Thinkpad Tablet Android Development] Tirofog:
Try 'pm disable-user --user 0 org.lineageos.snap'

[Thinkpad Tablet Android Development] Tirofog:
If you insist..

Your posts say different things ie Java exception, unknown package, then in original post failed to delete lineages* package.. ?

So.. either you're not rooted, haven't granted your terminal app root access, the package is not installed, or pilot error lol
[Thinkpad Tablet Android Development] kirknado18:
User is is an unknown package and yes I'm rooted and I'm not a newb. The Java exception is "user" user is an unknown package and I'm not gona keep trying to flash something that don't work. Camera settings to disable is greyed out in settings probly why it can't be disabled in terminal. Use to be able to disable camera in settings after most recent update of klineage 17.1 you cant

I have the TB-X704F (Wifi) and have installed LineageOS 10 together with OpenGAPPS. When the OS starts for teh first time i have to set up fingerprint (together with pattern or pin or password). There is no option to skip this. I don't want to use fingerprint - never. How can i skip this?

A few month ago i've already tested LineageOS 10 on this Tablet i can't remeber to this? At that time it was a little bit buggy.

[Thinkpad Tablet Android Development] wilvanwil:
I did some more reading in this thread, see a lot of initial problems have been fixed.

my checks for the day:

If you go to recent apps, is there a way to clean/delete them all easily, instead of having to scroll to the end of all of them??

GPS took some time to fix, I downloaded a gps check app,

after that that I did get a blue dot in maps for example, instead of a grey dot,

but after 2 minutes and typing this and checking it needed to fix again...

not as fast as my phone, fixing seems not very strong

anybody got issues with that? Is there a fix?

(must say I'm not sure I checked ever before)

-fingerprint scanner works fine

-gmail works fine

-led works

-bluetooth sound works fine to headphones

-battery % is in the settings: system, statusbar

-boottime from first vibration: 28 seconds(already installed about 30 apps)

18:53 100% battery test, youtube playing, bluetooth headphone connected, screen at about 85% brightness

21:14 83% ; seems fine for me

I installed TWRP 3.4.0, the June 20 ROM and stock GAPPS on my TB-X704N (Chinese Tab 4 10+ with 4G) two days ago. "About tablet" now reports model as TB-X704L. Issues: battery light shows multiple colors when unit is charging; FM radio doesn't work. Everything else is smooth and solid, including all the other radios (WIFI, Bluetooth, 4G, GPS). Issues I had with stability of newspaper apps on the stock ROM are gone. Thank you, codeworkx.

I just updated my Xperia XZ2 Compact to los 17.1, and it's working really good there. Thinking of upgrading it on my tablet to, which is currently running los 16.1. Although, I read that I should upgrade to latest official firmware first. Is that necessary when running los on it already? Is there a "easy" way to do it, like with Flash Tool for Xperia devices? I'm only running Linux, and most tools are for Windows unfortunately.

I've just moved from 16 to 17.1, and I've had a lot os trouble trying to make Dolby work. It always crashed. I've had it installed on 16, so I know how to install. Only after I removed AudioFX and installed viperfx from magisk, was I able to Run dolby without any issue. If anyone ir having issues, remove audiofx, install Viper, dolby (I have 7.3) and audio modification library, Change Linux se to permissive and it Will work.
[Thinkpad Tablet Android Development] kirknado18:
Dolby works with audio/fx but you have to turn audio fx off. I flashed Dolby digital plus 6.8 with audio modification library and audio compatibility patch. But for it to work you have to flash it with magisk 20.4 stable version. Canary debug versions of magisk will fail even if installed successfully
