The main problem is on the Redmi Note. 4 The error is often accompanied by a blockage. EDL-regime (9008), If the bootloader has not been unlocked before, which means that standard recovery methods through Fastboot may not work. In this article, we will discuss all working methods, including bypassing Xiaomi restrictions, taking into account the specifics of the mido model (3/32 GB, 4/64 GB and other modifications).
