[Help] Identifying Test Points for Forcing EDL Mode on Quectel EM060K-GL

Hello everyone,

I have a Quectel EM060K-GL modem that I need to recover after a failed firmware flash. The modem is still detected in the system but keeps reinitializing before I can force it into Download Mode (EDL, 9008). I need to find the correct test point (TP) to force it directly into EDL mode at boot.

What I’ve Tried So Far:

Using CONFIG_0 (Pin 21) → GND before powering on (no effect).
Using CONFIG_1 (Pin 69) → GND before powering on (no effect).
Holding RESET# (Pin 67) → GND for 5 seconds after power-on (still resets normally).
Trying to send AT+QBOOT or AT+CFUN=1,1 via ttyUSB2, but the modem resets too quickly.

Can someone help identify which TP can be used to force EDL mode on this modem?

Thanks in advance! Any help would be greatly appreciated.
