Hi, I'm trying to get a Mi3W from one of the older roms up to date. I'm got the partitions combined, Android 6, Miui 7 (6.1.21) with the normal Updater App. However I now have to switch to TWRP and install from there. The strange thing is that when checking with Fastboot I get the following info: Bootloader: Device unlocked: False. As Xiaomi only started to lock the bootloaders in newer models I'm surprised this popped up and I'm not sure how to continue. How do I unlock the bootloader (because I guess I will I brick it if I don't)?
