Thanks so much for your reply. Could you also elaborate which driver to use in Zadig and how to enter download mode to execute the above command? The thing is, I have tried both WinUSB and libusbK, pressing power+up+down combo, and the phone is still unresponsive, the terminal throws Waiting for connection and find port failed error. Thanks again!

uploaded libusb spd_dump to release

from cve-2022-38694_unlock_bootloader.

Thanks so much. I downloaded it and find libusb and SPRD folder, after comparing the date of spd_dump.exe, I used libusb folder as the working folder and also copied Channel9.dll from the other one into it, but the terminal gave me custom_exec_no_verify_3f28.bin does not exist. error. However, I used spd_dump_interactive.exe and could get to the BROM> prompt, so things are definitely going to the right direction. What shall I do next, thanks!

My phone is saved and it's been great! Thanks so much! Now I have the bootloader unlocked, Magisk installed, but still couldn't extract the boot.img with the updated spd_dump.exe and libusb driver, using the original address 0x3f88 (not the fallback address 0x3f28 as directed) with the command spd_dump exec_addr 0x3f88 fdl fdl1-dl.bin 0x3f88 fdl uboot-mod.bin 0x9efffe00 exec read_part boot 0 35M boot.img reset, the terminal gave me timeout reached error. Could you help please? Thanks a lot.
