[Request] HP EliteBook 8540p: WWAN Whitelist change/removel

[Meister_J]

OK, I've done.
Without success.
Look at the Video: https://www.youtube.com/watch?v=9hiT-1dk6k4
I think, the BIOS is complete erroneous. The USB-Stick is by power on, only short red, than off.

Ok friend,
i am sorry for this and It seems that BootBlock (Recovery need) is working but
something doesn't permit to load Bios !
I think You have to get the Tools (SPI PGM + Clip) to rewrite back the Firmware
and We will patch all You need this time and make any test !
They are cheapers ($.30,00 for all) and the procedure is easy !
Look here :

Before doing anything You have to read your Eeprom chips and make a

Thanks for the Software.

When i put the conector on the IC - the flashe not connect the IC.
I tested on old Mainboards the connector and it works.
I think, i must unsolder the IC, to Read and Write the IC.

All aligned to Pin #1 from SPI PGM to Eeprom Chip ?
If all is correct then You're right and You have to remove It from MoBo to read and write !
Let me know
