SL3(Security Level 3) = Nokia BB5 with PM 120 area and PM308 area is protected

Contact Service
“This faults means that the phone Software is able to run and thus watchdog of CPU can be served. Selftest Functions run when power is switch on and software is executed from combo memory. If any selftest fail, a “Contact Service” text is shown on LCD.”
Generally, failure is caused by selftest failure on security test and simlock test........
Security Test is related to PM 1 and PM 309 value , if one of or both value within the area is not valid, then selftest result on security test will be failed. Then comes “contact service”.
Solution : re-write area PM 1 and PM 309 using valid value

Simlock test is related to PM 120 and PM 308 value, when one of or both value within the area is not valid, then selftest result on simlock test will be failed. Then comes “contact service”.
Solution :
1. If the problem is on PM 120 value, you can try to re-write that area using valid backup (if you have). But if you don’t have, just make your own PM 120 section using some existing tools free, then ty to re-write the area...
2. If the problem is on PM 308, seems that no tool is able to fix it recently because PM 308 is protected, can’t be re-written.


I think PM 308 area has little possibility to corrupt because the area is protected, so if you have contact service problem caused by simlock test failed, it maybe mostly because of corrupted PM 120, not PM 308.

SIMLOCK invalid!
SUPERDONGLE_KEY seems to be valid
SIMLOCK_TEST failed!
SECURITY_TEST passed

The above log is not because handphone locked, but because one of simlock data (PM 120 area) corrupt. So, just fix it, no need unlock.
Unlock Provider is a process of opening provider key installed to nokia handphone that is locked on certain provider. Because one of simlock data is located on PM 308 area, so unlock cannot be executed for this moment, PM 308 is protected from re-write operation process through flash mode.
