My system crashed today and then the phone tried to reboot but is stuck eternally in the boot screen with the Mi and Android logo. I only had 100 MB free space, so maybe the system cannot boot because of that? I tried to clear caches with fastboot but it says "device is locked. Cannot erase". Also flashing TWRP is not possible. When trying to start adb shell it only says "error: closed". The newest version of Mi PC Suite cannot connect and an older MiPhoneAssistant version is only able to flash the ROM.

So I really tried a lot, but maybe someone has another idea with which I don't lose my data?
