MY DEVICE SITUATION- NOW It's hard brick stage due to flashing incorrect firmware. My device chipset is MT6891(Dimensity 1100), due to wrong firmware flash it's shows on MTKclint MT6893 Chipset. In your MTKclient >> payload section not having the payload file MT6891payload.bin, I hope it's the reson about the problem- " DAXFlash - DRAM setup failed: unpack requires a buffer of 12 bytes ". Please help me to solve my problem, if you have any question about thish concer please ask me.
