first step make full back up, and save,

secondly repair SD, sometime you may get error, do not worry,
go to the PMSolution for: "SECURITY_TEST failed!" and "warning: SD authorized but verify failed!"

If after repair SD and/or Simlock (Super Dongle RPL and Simlock RPL upload) you get "SECURITY_TEST failed!" and/or "warning: SD authorized but verify failed!".
This is comming usually because some PM fields and/or RPL sections are missing from your phone (e.g. DRM keys, CCC, ...).

Solution 1 (easy way, maybe not work all time, depends how phone was damaged):
- write full PM from SAME phone model C:\mobileEx\3.3\data\NOKIA BB5 PM Tested by Chevka
- unplug/replug phone from JAF/UFS box
- make Simlock RPL repair
- make SD RPL repair
- unplug/replug phone from JAF/UFS box
- make SUPER SX4 Auth then write PM1 and PM309

if still have problems, use Solution 2:

- backup RPL (NPC, CCC, HWC, ...), will call this ORIGINAL RPL
- backup RPL from another working phone (same model) with SAME product code
- edit this good RPL from another phone and remove NPC section (all lines who start with NPC_DATA_1 ... NPC_DATA_xx), will call this edited file CLONE RPL
- backup full PM from another working phone (same model) with SAME product code, will call this file CLONE PM
- full erase flash chip (use erase file regarding flash chip size)
- flash phone (CMT, APE, ...)
- upload CLONE RPL
- upload ORIGINAL RPL
- write full CLONE PM without fields 1,120,308,309
- unplug/replug phone from JAF/UFS box
- make Simlock RPL repair
- make SD RPL repair
- unplug/replug phone from JAF/UFS box
- make SUPER SX4 Auth then write PM1 and PM309
