- Nokia Bb5 Contact service Problem Reason & solution
SX4: SX4 Smart Card, is a tool or method which is developed by Nokia to
write some data protection for a specific area in EEPROM is useful for
preventing modification of the data.
When SX4 PROCESS is Required ?
In the case of a loss (data corrupt) data charging (not charging), data
network (no network). Dll.RF calibration calibration-charging.
So, all these problems caused by mistakes in the process of flashing or after
write RPL or erase process is done in a certain area
HOW DO I KNOW THAT MY PHONE PROCESS SX4 needs to be done?
When the phone appears CONTACT SERVICE, CONTACT retailers, NOT
charging after flashing, no network, etc. When the SELF TEST is done by
using the box like JAF repair, etc. will be obtained is the result of failed "ST_SECURITY_TEST Failed"
How do I make a SX4?
Plug the phone in the repair box (JAF, MTBOX, MXKEY, etc.)
Write pm area with 309 results read from the normal mobile phone or can
also write FULL PM area without 308 (SIMLOCK area).
What to do sx4 without internet connection?
sure Certificate damaged area musti made first with the FLASH erase, or
write RPL blank
Reset NPC (when using mxkey)
What is a Certificate Area?
Press info on the box like JAF flasher, etc. and see the results LOG ...
This is an example of the correct Certificate

BB5 Contact Service, Restart Problem,How To Erase BB5, Restore PM and RPL Backup!!!
I saw here many times peoples are having with this "Contact Service or Provider" problem
and also unable to Write or Restore the Orignal backup to the Phone. just follow and learned how to repair BB5 Contact Service/Retailer, how to erase BB5 and Restore PM and RPL Backup!!! Now we shall more reflect upon this matter;- How To Remove Contact Service or Provider ?
Firstly we should get Phone Info and see Imei and SL (Sim Lock) Zone are damaged or Not.Get Phone Info:
In Case when you got Damaged Imei: 123456789012345 and you dont have Orignal RPL Backup
then free way is try to solve this problem by downgrading if Imei and SP Data is still damage,
then Upgrade it back and you must need to buy an new RPL to fix this problem. Use ASK to RPL Service.
In Case when Phone Imei is oK but Only SL Zone is damaged and you don't have Orignal PM 308 backup then wat to do.If Courpted SP Data looks like this below:
CONFIG KEY: FFFFFFFFFFFFFFFF
PROVIDER KEY: FFFFFFFFFFFFFFFF
Provider: Unknown provider
And phone is supported for Unlocking, then you can try to Repair it free with any BB5 Unlocker by Unlock Button or with Repair SP Data Option. (It should Repair) Otherewise you may need to New RPL.
And If Courpted SP Data looks like this:
CONFIG KEY: 0000000000000000
PROVIDER KEY: 0000000000000000
Provider: Unknown provide
Then you must need to buy an New RPL whether Phone is supported with any BB5 Unlocker.
We can not Repair it free, Use Ask To Rpl Service.In Case when you have RPL Backup and have not PM 308, you can only Restore the Phone Imei but you can not Repair the Courpted SP Data like this: PROVIDER KEY: 0000000000000000,
Provider: Unknown provide In Case when you have PM 308 backup and have not RPL, you can Repair SP Data but you can not Repair Phone Imei by only PM 308 backup. Use ASK To RPL Service.
In Case when Phone Imei and SL Zone both are OK but phone is still on Contact
First take Self Test and check ST Security Test is Passed or Failed?
If Passed then do File System Formate and after that make Factory Setting and see problem is
solved or not, if still same then check phone hardware.
And if ST Security Test is Failed then Write PM Field  And  as stanner said,
(or full pm as you wish) by using SX4 Auth Service and after that make Factory Setting.
Oftenly Phone can Repair by Downgrading and Writing RPL.
Then Write PM With SX4 if same then Update back and See problem is Solved or not.
(It should work now!) otherwise try to repair it by erasing method.
How To Remove Restart Problem when Phone Imei is oK but Phone goes to Restart or Shut Off after a while
In this case first try to solve this problem by only Write Full Modified (Without 308 Field) PM With
SX4 Auth.Use SX4 and when it done Successfully then immediately Write supported full modified PM to the phone and check phone without MMC, problem is fixed or not, if not then Full Flash and after that Write PM with SX4, or try to solve
by Downgrading.Oftenly Restart problem is removed by only do File System Format and Factory Default. (Check
phone without MMC) Otherwise there is only one way is left to Repair it with Software and that
is Erase Flash (Rap), to start the Erasing Procedure,
Follow this given below Method:
Before Start Erasing Flash, Save your both backup PM 308 and RPL backup (CRT 308 and CRT
BKP)If you are going to do erase newer BB5 + (Plus) Phone then you must Save also Full PM 0 to 400
Backup, coz you will need it for restore the orignal field 308, this is really fast easy and perfect
way to restore the PM 308 Field, otherwise you may need to buy an new RPL.So be careful. . .
Now we are ready to do erase.Select UNI_rapido.bin in Mcu Part and click to Flash
and for MT Select uni_rap.bin as MCU.
when phone will fully erased then Phone Imei will be: 12345610654321, SP Area will damaged
and CMT Flash Data will shown: FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
Now Full flash with any Firmware ver but selected firmware should be not too Old or too New,
coz we may need it in another case.After Flash when phone will turn On, you will get
damaged IMEI: 12345610654321 and Courpted SP Area:
PROVIDER KEY: 0000000000000000, Provider: Unknown provide
Now first of all you have to Restore the Orignal backup of PM 308, in case when you are unable
to restore the PM 308 backup then flash again with same FW when you were take backup.
When it flash successfully then plz stay a min and write it (PM 308) back to the phone, now
Disconnect phone, connect it again and see SL Zone is Repaired or Not.
(It should be repair now), if not then flash again with same FW and restore the PM 308 backup.
But if you have Full PM 0-400 backup then no need to Flash again, just Write it (Full PM 0-400
backup) back to the phone without SX4,when it done successfully then remove cable to the box,
replug cable and get info you will see SP Area is Repaired now, if not then it will be repair after
writing RPL backup.
After successfully restore the PM 308 backup phone will on Contact Service/Retailers or full
working phone with damaged Imei. In this condition when phone has damaged Imei:
12345610654321 you can write full modified PM
(without 308 field) without using SX4, coz phone has not certificate (IMEI), therefor no need to
use SX4.Now we have to Restore RPL backup. If you are using JAF then Click on CRT Tool, now you will
see BB5 Certificate Tool Window
tick on Write RPL Option and also mark on Plain RPL box, now Select your RPL backup and
click on Write RPL button.Get info now and see Imei is restored succcessfully or not phone
should be on Contact Service/Retailer or fully working. . .
But if you are failed to restore the RPL backup, i mean phone Imei is still damage and phone
show only Nokia and then shut Off in case now you Write blank_rpl and Flash again with Latest Firm Ware.
When it (flash process) done successfully then write RPL backup, get Info and see Imei is back or
not, it (Imei) should back now, and your Phone will on Contact Service/Retailer, if Not and you
got dead phone Please follow again all above erasing method.
Finally use SX4 and Write PM Field  and  (or full pm as you wish), now we have done all
abt Software.I think That's all. . . abt BB5 Repair with Erasing Method and we have confirmed
now, phone has Software Problem or not.
only click thanks.......
