Hello,

GQ-4x can read the chip but didnīt erase the chip. I tried so many time but nothing empty. Blank Checking Gq-4x said " Device blank check failed at address 0x000000, Read= 0x91."

I tried to write new bios-file. GQ-4x worked fine with red-led, after writing without problems but verifing failed, I read the chip again and nothing changed in the chip.

Please helps !

First of all, you should be able to get corrct ID.

The chip need to be erased before write new data.

Do a blank check before write new data to make sure the chip is blank.
