Mi4 Lte Ct Bootloop After Installing Update


Apr 7, 2018

At first I've installed via MiFlash Chinese ROM (cacncro_lte_ct) and I turned on my phone and configured first options. Next I installed TWRP and then turned phone to factory settings, and afterwards I installed 8.4.4 rom downloaded from miuipolska.pl (exactly it's EU rom) but after installing phone has bootloop I waited 5hr and It doesn't work, also I can tell that after 20-30 minutes phone vibrates once and sometimes three times.

I must doing something wrong because yesterday I could update whit the same firmware what I've today

When I'm installing update.zip by TWRP there is an error:
unmount of /system failed: no such volume
script succeeded: result was [1].
