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...

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

I've tried it on my TB-8504X and it doesn't happen for me. Audio starts working when I disconnect the headphones. Which firmware are you on? Try S001031.

what am i doing wrong here ?

There's a typo in the META-INF/com/google/android/updater-script file. The 5th line is the following:

       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
