[REQUEST] Lenovo G510 (79CNxxWW) Whitelist Removal

[sovem]

Witam,
Hello,

I made an attempt to upload the modified BIOS by using the programmer CH341A, but the attempt failed:
 
1.     The programmer mistakenly recognized my chip detects it as a chip “128bit” instead of 8MB.
2.     I changed in the program to the chip COMMON 25X64.
3.     I made a backup of BIOS loaded.
4.     I programmed the chip with modified bios.
5.     Computer after step 4 did not start.
6.     I programmed the BIOS with my backup (created in step 3. - from the programmer).
7.     The computer is normally launched.

I am attaching my backup BIOS (programmer).

Hello Everyone.

I would love to have a modifided Bios on my Lenovo G510.

I know that i need a CH341A Programmer. I got one from Ebay and have the Software.

So now i have the problem that i could not read my Bios Chip.

For the Test a "old" Eon EN25F80 is working.

Here is the Picture of my Bios Chip(Winbond 25Q64FVSIQ).


 I Use a "Clamp" to Read the Chip like Rafal. But the Programm give me DEVICE STATE: NOT CONNECTED.

i Use CH341A Programmer V 1.17

Maybe someone could help Thank you

Wondering if you guys can help. I've a G510 which I'd like to remove white list and unlock bios features.

I'm familiar with read/write from car ecus.

I've obtained an eeprom programmer and clip as per tutorial but when I connect clip to eeprom the led in reader goes dim and program shows programmer as disconnected as well as win 7 making the disconnected device sound. Opposite happens when I disconnect the clip from the eeprom.

I'm assuming its USB power issue. My powered USB hub doesn't make any difference.

How can I get more power to the reader so I can get my bios read, modded and flashed back.

I've spent hours googling and can't find anything on adding external power to the programmer.

TIA.

Hi mate,
I suggest to follow this Tutorial and check the alignment to Pin #1 from Chip (is present a
ball on pin 1 = foot 1) then Clip to SPI PGM :

Then check if Eeprom Chip is detected !
Many times Clip doesn't work well as not good quality so You have desolder this Chip.
Let me know

I know the Tutorial
As i said i could read and flash a old "Eon EN25F80" Chip with no Problem

I use a "CH341A 24 25 Series EEPROM Flash BIOS DVD USB Programmer (C1B5)" and a "SOIC8 SOP8 test clip" for the Winbond Chip. But every time i CLIP the SOIC8 Clip on the Chip the Led on the CH341A Dimms and the Programm (CH341A Programme V 1.17) switch to "DEVICE state: NO CONNECTION.

Is my software to old? Or the chip too new? Icould not finde any infos about this chip .

I am a bit frustrated.

Maybe anybody could help me in a chat seasson or so.

Thanks
