For ATF Software 9.12 and above, you DO NOT NEED to follow the instructions below:
Some people have problems with some STOCK Firmware Versions
which does not accept the '00000000' PIN or '0000000000' PUK
Unlock Code after TP Unlock is Performed.
To Make sure you will have a WORRY FREE TP UNLOCK, I strongly
suggest that you should flash your phone to a very specific version.
1. Download NaviFirmEx_v1_6_1_en.zip from:
Downloads - navifirmex - Nokia firmware downloader - Google Project Hosting
Option --> Server --> Nokia Care Suite
2. Download 1750.0805.8773.12220 firmware version for RM-801 OR RM-819
3. Full Flash Phone with newly downloaded firmware
4. TP Unlock Phone and enter '00000000' when asked for SIM PIN Unlock Code.
After phone is unlocked, you can flash phone with any firmware you
want and IT WILL REMAIN UNLOCKED!!!
