If you bricked your phone while flashing with CFW, you can unbrick your bricked phone using Navifim to download your original firmware files. Installing a new firmware is to easy just follow my steps and if you know how to flash your phone then just download your firmware file

The Software you need to Flash your phone

[NOTE] Format your memory card via mobile or PC or at least delete everything in E:/sys, E:/patches, E:/private and E:/resource (and also same folders in F: if both mass memory and memory card are present as in new phones).

[NOTE] Remove SIM card and memory card from the phone

[NOTE]  Make sure to follow the instructions below very carefully

---------------------------------------------------------------------------------
Navifirm steps

1) launch Navifrm in your PC

 

1. Open Navifirm Folder, Open "FW" folder. 
2. Open Your Product code Folder.
3. Make your "RM-xxx" folder, Select & copy all files and paste it in Your Created folder "RM-xxx"
4. Move the "RM-xxx folder" in Phoenix Product Folder and flash your device with your OFW.
   

Now follow J.A.F instruction
1) Go to “C:/Program Files/Nokia/Phoenix/Products” and create a new folder to represent your device Type (eg: C:/Program Files/Nokia/Phoenix/Products/RM-596; RM-596 – Nokia N8)
[NOTE]  If you have Phoenix installed on your computer this path will be created automatically, if not you have to manually create each folder.

2) Install J.A.F. on your computer.

• Copy jaf_nok4models.ini (which should be in the JAF archive you downloaded) and paste it into C:/Program Files/ODEON/JAF
  [NOTE]  Confirm if you are asked to overwrite an existing file.
  
• Connect your device to your computer using the USB cable and select PC Suite Mode on your device.
  
• Make sure the device drives are installed to your computer
  

3) Once installation is complete open JAF using OGM_JAF_PKEY_Emulator instead of using the shortcut which appears on your desktop.
[NOTE]  This file should be part of the JAF archive you previously downloaded

• Click the ‘GO’ button
  [NOTE]  If you receive an error, try launching again.
  [NOTE]  If you are running a newer version that Windows XP, we suggest running JAF in compatibility mode.
  
• Wait for the emulator to verify the J.A.F. installation and for JAF to launch.
  
• When you see the error  “BOX DRIVER NOT INSTALLED”, click OK
  

4) Select the BB5 tab on the JAF window. Here you have three options to choose from:

Flashing your device to factory settings

• Select ‘CRT 308’.
• Select ‘Factory Set’.
• Select ‘Factory Settings’.
• Now click ‘FLASH’ under Operations.
• Wait for the process to complete and reboot the device.
  

Flashing a new cooked (custom or hacked) firmware

• Copy the custom/hacked firmware files (usually uda.fpsx, rofs3.fpsx) to the official firmware folder (eg:C:/Program Files/Nokia/Phoenix/Products/RM-596)
  [NOTE] The custom files should replace existing files from the original firmware files. If you don’t see any files overwritten head over to the folder and check if all files match the variant of your device. If not make sure to rename the custom files to match your firmware before you proceed.
  
• Once completed proceed with the rest of the guide
  
  

Update your device firmware to the latest version or reinstall the existing one with official files (downloaded from Navifirm)

• Select Manual Flash and Dead USB
• Uncheck CRT 308 and Use INI.
• Wait for ‘Select Phone Model’ to appear.

Find and select your device from the the box which appears and click OK.

1) If your device doesn’t appear in the box you may have to download a newer version of the jaf_nok4models.ini file
2) Place the downloaded file to C:/Program Files/ODEON/JAF and overwrite the file.

The MCU, PPM, CNT and APE Variant will now turn green:

• If your device is still not visible after updating jaf_nok4models.ini or if the circles don’t turn green
• Go to C:/Program Files/Nokia/Phoenix/Products/RM-596 and rename the  .core.C00 file to .c0r
• Now go to JAF and uncheck Use INI box.
• Next click MCS, PPM, CNT and APE Variant manually one by one and select the following files.
  

MCU – .c00/.c0r

PPM – rofs2

CNT – rof3

APE – uda

[NOTE] These files should be available in C:/Program Files/Nokia/Phoenix/Products/RM-596

• Turn off your device and click “FLASH” under Operations.
  
• A warning message should appear and you should click YES.
  
  1) Press the ON/OFF button on your device for a couple of seconds until the JAF flashing process begins.
  
  
• Disconnect your device from the computer, Remove and reinsert the battery and you are ready to boot back up.
  
  

[NOTE] If you face any issues after installing a custom/hacked ROM try resetting the device to factory settings. If you continue to face issues you should consider re-flashing the official firmware to your device using Navifirm.
