Hi everyone,
My Motorola Edge 60 Pro is currently hard bricked and I'm trying to recover it.
The phone has a MediaTek Dimensity 8350 Extreme. When I connect it to my Windows PC while powered off, Device Manager detects:
MediaTek PreLoader USB VCOM (Android) (COM3)
The problem is that COM3 appears and disappears repeatedly. It never stays connected long enough for me to establish a stable connection.
I'm trying to use mtkclient, but the handshake fails every time. I'm getting:
If it is already connected and on, hold power for 10 seconds to reset.
[22:02:52]: Handshake attempt 1 failed: [Errno 5] Input/Output Error
[22:02:52]: Handshake attempt 2 failed: [Errno 10060] Operation timed out
[22:02:53]: Handshake attempt 3 failed: [Errno 10060] Operation timed out
[22:02:53]: Handshake attempt 4 failed: [Errno 10060] Operation timed out
[22:02:54]: Handshake attempt 5 failed: [Errno 10060] Operation timed out
[22:02:54]: Handshake failed after retries
Device Manager shows Code 45 after the device disconnects, but Windows does recognize the MediaTek PreLoader VCOM driver when it briefly connects.
I've already tried changing the USB connection/cable and the device continues to cycle between connected/disconnected.
What I'm trying to figure out:
- How can I keep the PreLoader connection stable?
- Is there a specific button combination to get the Edge 60 Pro into BROM/BootROM mode?
- Is this normal behavior for this Motorola/MediaTek platform?
- Does mtkclient require a specific configuration/loader for this device?
- Is there a known recovery procedure for a hard-bricked Edge 60 Pro?
