So, on the TWRP you select Install and the window that appears does not contain the 'select storage' and install image buttons?From the TWRP app itself, I am now missing the option to update by 'select image'. I tried to look up how to update from internally but I feel I am getting stupid or something.
Also, I just updated to the latest Xiaomi.eu Dev rom while still on the 'old' A12 6.3, still works. Would pursuing to install the latest Recovery beneficial?
You use a TWRP A12 on a Rom A13, if you update via OTA and TWRP you must update the TWRP.
Otherwise you update with Fastboot since these roms are Hybrid.
