Pretty easy.

Use WPInternals and unlock the bootloader, enable root access.
When in Mass Storage Mode, goto EFIESP\EFI\Nokia\PCONF, copy “config.pcn” to somewhere and use a HEX editor to open it.
Change PXXXX_ATT to PXXXX (the XXXX is a 4 digit number, just replace _ATT with 00s), then save it.
Replace the config.pcn and soft reset, flash an unbranded FFU and you are done!

No need to thank. I know you have been looking for this :)
