I’ve searched for and followed pretty much every recovery instructions online and can’t find anybody else who’s had the following issue.
Host computer is Debian 10 (both WSL under Windows 10 as well as native). Removed “modemmanager” package as per some recovery instructions.
Hikey960 v1, jumpers 1 and 2 are bridged, 3 is open (ie, pins 1-2, 3-4, 5x6)
Console shows nothing (as expected).
Trying to recover with hikey_idt, it always hangs indefinitely (several hours) at the following step:
bootloader$ sudo ./hikey_idt -c config
[sudo] password for micha:

Device is connected to ttyUSB1:

Note that the device does not time-out or disconnect when in this state. When reset in recovery mode without launching the recovery utility the USB device is only active for ~90 seconds (as expected).
Would be grateful for any additional troubleshooting steps.
With best regards,
