Winbond's your bios chip. Unlock it with RC Unlocker.

Re: hp 450 g7 password

Hi Peste,
Thanks, but no success. The prompt for pass remains the same. So clearing the part of starting with "NvramActiveRegn." (GD125B127D) was not helpful.

So I flashed back original (locked) dumps. Laptop works untouched, as arrived - asking for password. This means, that reading/flashing (with reduced clk) IN PLACE must be 100% OK.

Maybe Im missing something.
Please see attached image and explain, if possible.
There are two chips, both 128Mb (16MB)
- GigaDevice GD25B127D (dump starts with a block of FF values)
- Winbond W25Q128JV (dump starts with various values)
Please:
1) Which of them is the main one?
2) Which of them should be altered by RCUnlocker?
Many thanks for your time.

Re: hp 450 g7 password

I did exactly the same thing but the password is still there. Can it somehow be recorded on the second EC flash?

Maybe.

Re: hp 450 g7 password

remove the bios chip from the motherboard before reading or writing it, don't use the clip because it gives errors..
try..

Many thanks for your great work and info. Yes I have readed and also programmed both chips in place.
May I ask a question?
I have T56 and I lowered the clk speed to 5 MHz. The chip (both) powering resistance is bigger than 15 kOhms.
I readed both chips TWICE and checked for differences (HEX, CRC). Both saved dumps for both chips were OK. No differences. Is it possible to read twice in place with IDENTICAL errors?
If is this possible, it menas, that also the second chip Winbond W25Q128JV was readed improperly and need fix.
May I ask also for fixing the second one - Winbond, in this case?
Many thanks!
