Update 3 (I think)...
I finally managed to flash RevengeOS-3.1-Q-BETA4-zippo-20200119 (the old ROM)
I had to restore the phone from EDL a few times...
I don't know what I did wrong...
Maybe I had a bad version of ZUI??? (can someone post a good link?)
Anyway, after a LOOOONG day (and night), I finally managed to get my phone up and running again (although now I need to find a good SD card recovery tool after an accidental SD card formatting in TWRP...)
