Need help!
I'm trying to flash a custom ROM, and have tried this one (along with others). I have unlocked bootloader, and can flash custom recovery (using twrp).
I'm starting from miui 10.3.3.0
Boot to recovery, wipe everything (including trying format data), then install custom ROM (I've tried LoS + gapps stock and Pixel Experience). The flash seems to go OK, however the phone then gets stuck in a loop, it shows the bootloader screen, then reboots, and just does that!
I can successfully flash back to MIUI Global, and it boots fine, but every time I try to reflash to a custom ROM, back to bootloader loop again!
Any advice?
Edit:
by following this procedure:

I managed to get Lineage OS sort of working, although it feels buggy (probably from the dirty flash at the end).
I then updated the FW to 10.3.3 (via
https://forum.xda-developers.com/mi-mix-3/development/firmware-xiaomi-mi-mix-3-t3955361) - and have succesfully wiped and installed other custom ROMS, so am assuming you could then do a clean install of LoS.
