I tried to install this but ended up in a bootloop stuck on the RR logo (for over an hour). I tried going back to stock using the Lenovo rescue tool, which mostly works, but the tablet no longer has any Wifi. Any suggestions? I'm hoping reflashing the boot.img would help but I can't find a copy of that file anywhere -- if anyone can provide that I'd really appreciate it... thanks
Make sure you're on the Oreo firmware. LineageOS 16.0, 17.1 and all ROMs based on them boot only on the Oreo firmware. I once tried it with the Nougat firmware, which ended up in a bootloop.

Are you on the latest stock firmware? Also, did you wipe data,cache,Dalvik/ART cache after installing the ROM?
After installing RR, yes, I wiped all those. Stock version I am trying to go back to is TB_8504F_USR_S001019_1909091114_Q12000_ROW -- Since I had no pending updates prior to trying to install RR, I assume that's the one I was one prior

Which firmware are you on? (Post the version number) I'm on the latest 0031 based stock firmware and the calls (outgoing) don't work on LOS 17.1 based roms, also, I'm pretty sure that the dev removed a file that's responsible for outgoing , so, I'm not really sure how outgoing works for you, so, please provide the firmware version so that I can install it and test it myself and also to see if the outgoing calls work...
Build no. rr_TB8504-userdebug 10 QQ3A.200905.001 eng.contro.20210519.144927 test-keys
Firmware : TB_8504X_USR_S001024_1909061423_Q12000_ROW_SVC

Will definitely try this and let you know!

EDIT - I went back and reinstalled RR, and this time it worked, Wifi is also back. It's an odd MAC address but I can live with it, I think there's a way to fix that if I need to, thankfully I still have the old MAC address noted down somewhere. Thanks for your help!

My steps were:
- tried Lineage 17.1 + nano GApps, but had boot loops.
- tried RR + pico GApps, and things started to work properly.
- tried Lineage 17.1 + pico GApps, and had boot loop again.
- have stayed with RR + pico now.

I have not felt the need to go back to stock...

Try a different gallery app.
I have this problem too and it does not depend on gallery app, it shows green thumbnail in every app like Whatsapp or VLC.
but not on every thumbnail, apps shows some thumbnail correctly.
and this problem was in Los 16 and 17.1 too.

edit :- i am sorry i accidentally posted it multiple times, can you delete the other ones

i had tried it in past on this tab and it worked.

I will say one thing though, I think my bootloop issues were caused by rooting with Magisk. I got the tablet working again, and as soon as I fashed a Magisked boot img, it went into another bootloop. Had to reflash again from scratch and once again that fixed the problem. So this may be a one-off but rooting this tablet appears to be too risky for me right now

Just use the magisk zip file, root works just fine, I'm not sure why your device doesn't boot, but, just download the Canary version of magisk and flash the . Zip in recovery

Resurrection Remix the ROM has been based on LineageOS, SlimRoms, Omni and original Remix ROM builds, this creates an awesome

combination of performance, customization, power and the most new features, brought directly to your Device.


Many things that in previous versions were tweaked with mods, are now included by default in the ROM so, please enjoy!

Special thanks to the LineageOS team, Omni team, SlimRoms and of course to all the supporters.

Bugs:

  • SELinux permissive - temporary fix for WiFi and Bluetooth.
  • Same issues as in LineageOS 17.1 builds - audio in calls doesn't work, you need this patch in /system/build.prop; after this fix only incoming call audio works.
  • Double tap to wake (broken in all ROMs)





rrinstall.png



Make sure you have a custom recovery installed(TWRP is the preferred recovery)
Download the latest Resurrection Remix Rom & the latest GApps package
Boot into recovery
Perform a FULL factory wipe and wipe/system and dalvik cache as a precaution
Flash ResurrectionRemix Rom
Flash Google Apps package(Optional)
Flash Magisk Root(Optional)
First boot may take up to 10 minutes.

    @adazem009 , may I ask the exact specs of your tablet just in case?

    Mine is TB-8504X, have sim slot LTE.

    Snapdragon 425, 2GB RAM and 16GB of internal storage, 5MP back camera (I think there is a 8MP variant).
    Same (5 MP back camera)

    @adazem009 @Hausemaster Fantastic job! I've loaded it on my 8504F.

    Only issue I can find was on initial start, I declined the face unlock, and that prevented my going any further. I rebooted, and reflashed, but it kept saying I needed app permissions...

    So I flashed LineageOS 17.1 (which has never worked for me - caused a boot loop), then re-flashed Resurrection and this time accepted face unlock.

    And now, it feels like I have a brand new tablet!

    Thanks guys!.
    You're welcome :)
    Next build is probably going to come next week. It's going to fix screen recording.
