Good afternoon. Tell me, I'm recording the flash memory 25b256dyig of this laptop using CH341A. There is no adapter, soldered directly to the flash drive, reads normally, but writes only zeros, after writing one FFFFFFFFF and 00000000

Your Backup file not good, try to read it again correctly and also write your device Service Tag.

Hello,

It should works with any device has the same model number and board number, maybe you will face some issues because it's not your Original Bios.
The best way is to upload your Original Backup, write your Service Tag and someone will try to help you.

Hi for unlocking bios password

Hi for unlocking bios password

At first boot press F2, write the service tag, save & restart. After that at the second boot press Alt+F to exit manufacturing mode. And the fan will slow down.

First boot will be much longer than usual just wait, if you have programmed and soldered the chip as it should everything will be OK, if not do it again.
