Please Build Havoc OS Rom Please
Firstly, the Dev is working on Los 18.1 for this device the current status is that the ROM gets stuck at the boot animation, what we can expect from this info is that, as soon as the Dev boots the Los 18 ROM, then he will be able to use similar device tree and overlays from it and build other more feature rich Roms, etc... Till then, we'll have to wait... Or, if the Dev decides to implement treble by repartitioning and building a specific custom recovery with the updated partitioning support and fully fledged treble overlay implementation, then, we can just use any other treble based ROM, and even treble images directly from Google if a/b partitioning is implemented, but, since this device has only 16 GB of internal storage, implementing a-only is a necessity to store any userdata...
Edit: the Dev already tried to build Havoc, but, it ended up not recognizing any Sim cards, so, he had to scrap that idea, and also since Havoc ended android 10 support, the Dev chose to build RR since RR still gets updates for android 10...

These instructions should help you


for ERROR: 7 you can unzip the OS and then go to meta inf and try to find update script in any of the folder ,,, open it in notepad and edit the codes and replace tb-8504X with tb_8504X and then save it as it is ,, without having any extension ,, compress it again amd then try

for "Failed to mount '/data' " ,, In the menu of twrp recovery --> wipe -> Advance wipe-> select data -> click on repair and change partition -> click on repair partition and swipe -> come back and click on change partition and change to partition to FAT OR exFat by swiping -> and again change your partition to EXT4 -> come back to main menu ,, -> Reboot ->Recovery
Edit: I also think you aren't on the latest firmware S000031 to be exact, upgrading to this firmware fixed error 7

There's a typo in the META-INF/com/google/android/updater-script file. The 5th line is the following:
Code:
       getprop("ro.product.device") == "tb_8504" || getprop("ro.build.product") == "tb_8504" || abort("E3004: This package is for device: TB-8504X,TB-8504F,tb-8504x,tb-8504f,tb_8504; this device is " + getprop("ro.product.device") + "."););
Notice that "tb_8504" is listed twice. One of those should be "tb_8504x." I edited mine locally and it installed successfully. @adazem009 you should fix the upload.

This issue isn't present in the latest firmware for this device, download it from here https://firmwarefile.com/lenovo-tab-4-8-tb-8504x
Download the S001031 version, then start up qfil and put the device in edl mode, hold both volume up and down buttons before connecting to PC or just reboot to edl from twrp, then it'll install the for!ware and you'll be ready to go from that point

    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:

    • Same issues as in LineageOS 17.1 builds - VoLTE doesn't appear in settings.
    • Double tap to wake (broken in all ROMs).
    • Screen recorder doesn't always work.

    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)

    If you have a major bug to report that has not been reported already, please take the following steps to report it to us. It will save you, Team Resurrection Remix and me quite some time.

    Download the MatLog app from the Play Store.
    After downloading the MatLog app, go to the app settings, and change the log level to Debug.
    Clear all previous logs and take the exact steps to produce the error you are receiving. As soon as you receive the error (probably a force close), go straight into MatLog and stop the log recording.
    Copy and paste the entire log either to Hastebin or Pastebin
    Save the log, and copy and paste the link into the thread with a brief description of the error.

    @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.

    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
    i had faced similar problem( wifi mac address 02:00:00:00:00) when i flashed stock rom(through lenovo assistant) after a bootloop, than i again flashed custom rom(lineage 16 in my case) and wifi start working but wifi mac address changed to different one, than i again revert back to stock rom and everything working fine , i hope it will work for you, (currently i am using RR ROM).

    Have to thank you again to your work, you're a absolutely legend for keeping our device has more life.

    But edit: After dirty flash, Wifi and Bluetooth dead again. :D
    That happens on some devices for an unknown reason. On my device it works fine, but only some people have got this problem. It's probably something related to the latest security patch because it happens on crDroid too. (it's another ROM that's coming today btw).
