Hello everyone,

I’m trying to flash the latest Xiaomi.eu ROM on my device using a MacBook M1 with an original Apple Type-C to Type-C cable. Normally the flashing process is very fast, but sometimes it becomes extremely slow — especially when flashing the super.img parts (super.1, super.2, etc.). for hours without completing.
My setup:
macOS (latest version)
Official Apple USB-C cable
Latest platform-tools
Device detected normally in fastboot mode
The process seems stuck.

If I disconnect and reconnect the cable while flashing, will it cause any problem such as bootloop or bricking the device?

Thanks in advance!
