I am looking to remove the bios wifi whitelist restriction for a Lenovo G700 version 7ACN89WW . This is version 3.07
I have used a programmer to read direclly from bios chip but it has failed. Is there any other method available to remove bios restriction from this laptop?
Hello everyone! I am looking for an answer to a problem I cannot find a solution to ... I purchased an Amd wx 4150 MXM GPU module su e bay to upgrade my HP 8570W Mobile Workstation which is currently equipped with a Fire Pro M4000. Once the new GPU has been installed, the PC screen no longer turns on but works only with external monitors connected via the docking station. The same happens once the drivers are updated! If I put the old card back on, the integrated monitor starts working again ... How can I fix it?
In this thread you can post your requests for Lenovo ThinkPad T440p / T440s / T540p.
If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, then you can post your request in this thread.
For creating bios backup and to flash bios mod, you must use any SPI programmer (like CH341A programmer) and a SOIC8/SOP8 test clip!
Just dump your Bios using any SPI programmer (like CH341A programmer) and a SOIC8/SOP8 test clip, then post it in this thread or upload it to any fileserver and send me the link.
I would love to have my BIOS modded to disable the wireless whitelist.
I tried to do it myself (dump BIOS from chip, disassemble, locate the reference to the error message "Unauthorized Wireless network card is plugged in..." memory address and modify the condition in the binary file so not to "land" in the infinite loop) but I couldn't dig to anything meaningful I could easily change.
