Hi! I've got a TB-8504F and I'm experiencing the same problem as @powermaker450 ("the device freezes, then the screen turns black and won't respond until a hard reboot is performed" = Kernel panic). No GApps or MicroG installed. I've attached the console-ramoops file I managed to get.
Edit: I added the .txt at the end of the file name in order to be able to attach it.

Hi. Having the same issue @FutureLizard205 and @powermaker450 report. It happens as soon as the screen turns off automatically after a few seconds. This is a freshly installed version with Nov 22 security patch and NikApps Core. Reinstalled to test and it happens again. What I did consciously after reflashing: set up my Google Account, installed my beloved Firefox and set the screen display brightness to auto.
Edit: also happens when using the device with screen on. It's crashes pretty regularly, also without Gapps as well as on CrDroid.

Did you upgrade to Android 8.1 before flashing the ROM? Did you format data and cache after flashing it?
Any idea what I can try to fix this? It seems this is affecting more users. Any luck yet @FutureLizard205 @powermaker450 ?
Not yet.. I'm using an Android 10 ROM at the moment and no problems there.

Hello. After much effort I successfully passed lineage-16.0-20200319-UNOFFICIAL-TB8504. I want to ask if this
LineageOS 18.1 is better, more stable without problems to pass it. Or to stay in?

Nah, there are random freezes even without gapps or magisk. But lineageos 17.1 is pretty stable IMO.
Download your preferred gapps ( i preferred bitgapps bcoz occupy less space and it is magisk flashable)
Bitgapps : https://bitgapps.github.io/download.html
Opengapps : https://opengapps.org/
Flame gapps : https://flamegapps.github.io/download#downloads
Light gapps : https://sourceforge.net/projects/litegapps/

Hi guys,
please help me with flashing TB8504X.
I wanted restore tablet by Lenovo Rescue and Smart Assistant, but even if process was done successfully, after reboot tablet was still rebooting on Lenovo boot logo (no OS is loaded).
So I decided try to flash by alternate OS, but I am unable to finish it successfully.
I tried several ROMs of lineage (16, 17.1, 18.1) and crDroid from adazem009, but still although flashing is done and tablet is rebooted - android system hangs on system boot animation (logo of Lineage or crDroid).
I was only successfull with Ubuntu Touch from adazem009 but there is problem that WiFi not works (wlan interface is not created in system). Back to droid's OS.
Hardware is working but maybe I still miss something and cannot load OS.
Steps I done:
1) installed TWRP 3.3.1 via fastboot
(tried PBRP as well, with same result)
2) wiped data, cache, dalvik and system partitions
3) rebooted back to TWRP
4) pushed up OS zip file via adb
5) reboot device
Result = OS probably is booting, I can see animation boot logo of Lineage (or crDroid) but it is all. Can't get welcome screen (or what should be there).
Result is same with every *droid OS.
Thanks a lot!

Hi Adazem,
unfortunately I don't know which Android was installed before. I suppose not as it was delivered with Android 7.
As first alternate ROM I tried LineageOS 16.
I tried to install latest stock ROM with QFIL but without success, it is probably Windows only app.
Is there way how to install stock ROM from Linux?
Do you have recommended stock ROM?
Thank you

LineageOS is a free, community built, aftermarket firmware distribution of Android 11 (R), which is designed to increase performance and reliability over stock Android for your device.
LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.

- Boot
- RIL (Calls, SMS, Data)

It's happening to all of us (see the "Known issues" section above). Updating some vendor blobs should fix it, but I think I'll need some help with it.2
Yes, I'm still working on it. I'm still waiting for Android 12 CAF releases targeting to msm8937. After they''re there, it should be possible to build it using the device trees from Android 11 (with a few changes).
