Solusi 5130c Contact service (Simlock and security)

Solusi 5130c Contact service (Simlock and security)
5130c RM 495, is Nokia BB5 of SL3 category... therefore, many people say that this type is not supported for unlock and simlock repair as well as contact service reparation.
Is it true........???
Hmm.....before elaborating the facts, there is an important question: what is SL3 or Security Level 3?
We better understand from the beginning......SL1, SL2, SL3..........
There is a lot of informations in many forums but each explains differently. However, based on my concern and belief, those are classified as the followings:
SL1(Security Level 1) = Nokia BB5 first generation which doesn’t have PM 120 area
SL2(Security Level 2) = Nokia BB5 with PM120 area and the area contains simlock data connected to PM308 value
SL3(Security Level 3) = Nokia BB5 with PM 120 area and PM308 area is protected
I’m very welcoming for any correction.........
Based on the above classification, the next question is “what can be and cannot be done on that each type???

SL1
Flashing = can be done
Write PM 1 and PM 309 = can be done (using SX4, reset NPC, BYPass CRT)
Write PM seluruh area = can be done
Write RPL = can be done
Unlock = can be done

SL2
Flashing = can be done
Write PM 1 dan PM309 = can be done (using SX4, reset NPC, Bypass CRT)
Write PM seluruh area = can be done
Write RPL = can be done
Unlock = can be done

SL3
Flashing = can be done
Write PM 1 dan PM309 = can be done (using SX4, reset NPC, Bypass CRT)
Write PM area 308 = cannot be done
Write RPL = can be done
Unlock = cannot be done
NB: SX4 process through bypass certificate sometimes not perfect.....hence, it is suggested to use SX4 Auth via server...

5130c(RM 495) = Nokia BB5 SL3, Is it possible to fix contact service case on this handphone????

First, we better understand on how contact service case emerge....

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.”

The point is, when handphone switched on, then cpu will perform several test (selftest). If one of selftest fail, then “contact service” will show 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 dan PM 309 using valid valuei


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 0 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 (some says it could be by using some tricks).


What I believe is, 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.

Exampleof log caused by corrupted PM 120...

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


SIMLOCK_DATA corrupted!
Additional for UNLOCK......
“5130c is Nokia SL3, not support unlock, wait for update...” this is true, but this sentence often put on a wrong place so i think rather misleading.
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.
