Request: x250 BIOS mod (screen/wwan/menu)

Recommended Posts

HI forum,

 

can someone help or explain to me, how to achieve the following mods:

  1. Remove screen whitelist
  2. Unlock advanced menu
  3. Remove WWAN port whitelist
  4. Have those mods without beeping on start due to missing  / mismatched checksum

 

I did try to create my own screen whitelist mod following a tutorial and it worked, but I do have those beeps upon coldboot...

I have a ch341a programmer for flashing and dumping

 

Bios with screen whitelist mod and beeping: https://www.dropbox.com/s/hzwzolbsau3sp8w/moddedx250bios.zip?dl=0

Unmodified BIOS dump: https://www.dropbox.com/s/svjpi02mza6me4i/originalx250bios.bin.zip?dl=0

 

Cheers
