I read 25rh256cxiq with NeoProgrammer and AsProgrammer (CH341A interface) 6 times. I have 3 bin identical. I choose W25Q256JW, MX25L25673G and W25Q256FV, because i dont find my bios - 25rh256cxiq. I think is ok.
Thanks.

P.S.: i think the last file is ok. (locked.bin)

Tôi đã đọc 25rh256cxiq với NeoProgrammer và AsProgrammer (giao diện CH341A) 6 lần. Tôi có 3 thùng giống hệt nhau. Tôi chọn W25Q256JW, MX25L25673G và W25Q256FV, vì tôi không tìm thấy bios của mình - 25rh256cxiq. Tôi nghĩ là ổn.
Cảm ơn.

PS: tôi nghĩ điều cuối cùng là ổn. (bị khóa.bin)

Where's backup bios file ?

Laptop alive.With CH341A programmer+wson8 6x8+NeoProgramer. But wson must be fixed to read/write. The process takes approx. 4:20 min for reading and approx. 8 min for erasing, writing and checking.
Thanks for help.

please unlock this bios

[SMDFlea]

Please read the rules,you must post the service tag. Also,i noticed that your backup is only 139KB ,you havn`t made a good backup or you chose the wrong chip.
