Linux Fastboot: FAILED (Write to device failed (Protocol error)) on Redmi Note 5 (whyred)
Hi everyone,
I'm trying to flash TWRP recovery on my Redmi Note 5 (whyred, Snapdragon 636) using Linux, but I've hit a wall with a Fastboot protocol error.
Device & Setup Details:
Phone: Xiaomi Redmi Note 5 / whyred (Qualcomm Snapdragon 636)
Bootloader: Unlocked
Root: NO
OS: Linux
The Issue:
When the phone is in Fastboot mode and connected via USB, running commands like sudo fastboot flash recovery twrp.img or sudo fastboot flash boot twrp.img fails with this exact output:
FAILED (Write to device failed (Protocol error))
The device is detected by fastboot devices, but any attempt to write to partitions fails immediately at the transfer stage with this low-level protocol error. Any advice or workarounds would be greatly appreciated!
