Xiaomi 13 (CN hardware flashed to Global ROM, locked bootloader) — HyperOS 3 OTA crashes to Recovery. Want to flash back to CN ROM.
Hi everyone,
I bought a Xiaomi 13 — Chinese version, but the seller flashed it to the Global ROM. On HyperOS 2.0.203.0 everything worked without any problems.
But when I tried to update to HyperOS 3.0.3.0, the phone crashed into Xiaomi HyperOS Recovery. After about 10 reboots I was able to get out, but then apps started crashing constantly. In the end, only a full factory reset fixed it.
HyperOS 3.0.304.0 is already out, but I haven't tried installing it, because the crash into HyperOS Recovery happened on every single update attempt. The bootloader is locked.
I want to flash back to the Chinese ROM, as that should apparently solve my problems.
I've read that flashing via EDL might help, but I can't find a master cheaper than around $70–100 (converting from my country's currency).
If anyone knows: a way to flash without EDL, or a way to flash via EDL but cheaper, or a way to unlock the bootloader and flash it myself —
I'd be very grateful if you'd share your knowledge with someone who understands very little about HyperOS and its ROMs.
And sorry, I did this translation (since I’m not from an English-speaking country) using Qwen.
Thanks in advance!
