ok.now download your firmware

after downloading make a folder in C:\Program files\Nokia\Phoenix\Products\ named RM-your rm number

eg: C:\Program files\Nokia\Phoenix\Products\RM-638

now put your all firmware files in that folder[normally 4 or 5 files]

i e:


1. Be sure you install updated firmware. You cannot downgrade your phone’s firmware in BB5 phones which includes all new Nokia phones including N-Series.
2. jaf allows downgrading but your phone doesn’t allow it as your phone has some special security built into it. So no use of trying it. You’ll get an error message.
3. You can reinstall your current firmware also if you have its package. It is supported. It can also sometimes solve little issues.

lets start

1. Conect your phone with PC Suite Mode
2. now open OGM_JAF_PKEY_Emulator_v3.exe

3. click GO

3. Error: BOX DRIVER NOT INSTALLED click OK.thats usual

4. Select BB5 - Manual Flash- Dead USB- Use INI

5.Select your phone model

8. You will see MCU, PPM, CNT, APE Variant become green

9. Now TURN OFF your phone !! and then click FLASH button after that press power button (don't hold it) on your phone and JAF will start flashing.

10. When flash will finish restart your phone (by releasing your battery and put it back)
