[Moto G7 Power ROMs, Kernels, Recoveries, & Other D] ViRUS2015:
Hey!

So, I tried installing this, and I've encountered a roadblock. I think I've got all the steps from "Preparation for A/B Roms" category right, my issue appears when actually flashing the LOS zip file. When I'm on TWRP and I go ahead and try to Install the ZIP, it simply stops after "Done processing script file" (after both steps of Checking for Digest file... are complete) but actually there's nothing on the internal memory of the phone. This means that after rebooting, I only get a bootloop on the "bootloader unlocked" warning screen.

Some things to note:

I've copied all required files to the microSD card on my phone, and I'm trying to install everything from there.

I've been doing all the TWRP stuff from the CMD prompt in Windows using ADB because for some reason the touchscreen won't work on my phone while using the unofficial port of TWRP.

I've copied a log file from my console right after step 6 of the preparation, that is, flashing copy-partitions-payton.zip up to where I get stuck, in case this is helpful to help whoever wants to lend me a hand with this :)

The good thing is that I was able to recover the original system image from the lolinet file I downloaded, so my phone is fully functional and ready to give it another go hehe.

Any help will be more than welcome. I'll try giving it another go on my own during the weekend.
