A week ago I put TRWP recovery on my X3/K9 so SPFlash Tool and driver worked fine. I also used MTK Tools to reboot in recovery mode and then install superus.
Now the problem is that I’m trying to make a full firmware backup with “read back” from SPFlash tool but when I hook to the cable the read back doesn’t start.
I switch off the smartwatch first, I press the read back on SP Flash Tool, then I hook the cradle but nothing happen and the smartwatch start charging.
I didn’t disconnect the battery but I didn’t disconnect it when I put the TWRP recovery neither. I would prefer not try to disconnect the battery. Is not so simple and I don’t wanna damage it.
What can I do?
