Hello,
Thanks for the helpful Information.

other question, is it possible to modify the .bin deleting the password and replacing by “00″ hex value at line 0×330 and 0×340 ?

Allways same problem with X61 from China :

0×330 -> 00 00 00 00 00 00 00 00 - 8f ab 6b a3 30 71 49 dc

That mean in scancode mode i obtain this result :

Off: «k£0qIÜ
On: B 9

Question : Is it possible to enter ”Ü” with a qwerty KB ? and is it normal to choose translation OFF ?

Thanks for this. I have just made this and successfully recovered a password for TP R40. It only cost me AU$15 for all the parts, which saves getting another motherboard.

To KWEB & nino,
Just make sure that the translation if “OFF”, I had that problem until I realised that the translation was on.

Sorry for my poor english …
I’ve got a chinese X61 with qwerty keyboard, everythink worked well, but when i try to convert the HEX value, it give me this at line 330 :«k£0qIÜ (with a space before )
and with AA on, the equivalent is ” B 9 ” (with 4 spaces before)
Question : is it because the password had been registered with a chinese keyboard ?
Is there any possibility to convert this Hex value, to send it logging on a qwerty KB ?

too hard for me, please help … thank you very much

From Paris, France Really Sorry for my english
