I want to install an open ROM like AospExtended on a new Xiaomi Redmi Note 5 with stock MUI. To avoid issues with Xiaomi's anti rollback mechanism, I'd like to boot TWRP then copy its image and install it permanently as described in many posts like here.
But TWRP can't mount my data partition, it asks me for a password. I had none set. Regarding to this post I tried setting a password for the lockscreen. Altough he has the same problem with an older version of android, it doesn't accept the password.
With 9.0.2 of OrangeFox it doesn't ask for password any more, so this seems to work. But why isn't it working with TWRP? This post said it's fixed in
3.2.3_1. Since I booted 3.3.1-0 like this:
> .\fastboot.exe boot D:\Downloads\twrp-3.3.1-0-whyred.img
This fix should be included. As a workaround, I'll try OrangeBox (especially in regard to OTA updates, havent tried OrangeBox before). But I'd like to know why those problem exist with TWRP and how could it be fixed?
I've used TWRP over the time with different devices and it always worked well (also with OTA updates).
