How To Install N97 / C6 firmware on Nokia 5800 - Detailed Tutorial Guide

JAF User Interface
1. Download the C6 firmware files from any ONE of the below links depending on your fone type:-
C6 Firmware for Nokia 5800-RM-356 PNHT Files
or
C6 Firmware for Nokia 5800-RM-428 PNHT Files

2. Unzip using winrar, google for winrar if you dont have.

3. You will get a folder 'C6_firmware_for_Nokia_5800_RM-356(symbianzone.co.cc)' or 'C6_5800_RM-428(symbianzone.co.cc)' with 6 files in it, keep it.

4. Download JAF and the pkey emulators from HERE
The JAF is a complex software and uses a hardware device actually to flash Nokia Phones known as Pkey dongle. We dont have it, so we use the pkey emulator to fool JAF thinking that we have the Hardware. It will be tagged as virus by most antivirus, but ignore it, its safe.

5. Unrar the files and install JAF to the default directory in program files. DO NOT CHANGE THE DIRECTORY or the pkey emulator will not work and you will have to reinstall. Do not run anything.

6. Copy the pkey file to \Program Files\ODEON\JAF and create a shortcut for the pkey file on desktop after deleting all other JAF shortcuts on the desktop. The location can be "Program files(x86)" for a 64-bit OS.

7. Run the pkey emulator link shortcut on the desktop. A windows with lots of emulation types open up, forget it all and press RUN. A red JAF splash screen will pop up followed by an error "ERROR:BOX DRIVER NOT INSTALLED", click OK and JAF will open up.

8. You will see 3 tabs, DCT4, BB5 and P-key. Our phone is BB5 type, so click on it.

9. There will be lots of check boxes, enable 'Normal Mode' and disable 'CRT 308'.

10. Now enable 'Manual Flash' and 'Dead USB'.
11. Finally after the above two steps, enable 'Use INI' and wait for 10 seconds to allow the phone selection box to open.

12. A 'Select Phone Model' box will open and look in the second column for Nokia 5800D-1 and make sure left is RM-356/RM-428 depending on your type and click ok. 'Use INI' will still be disabled, leave it.

13. Now in the status and results box JAF will show the location it searches for the firmware flashing files. Note the location. It will be something like "C:\Program Files\Nokia\Phoenix\Products\RM-356\ or C:\Program Files\Nokia\Phoenix\Products\RM-428\

14. Goto that location from 'My computer' and if such a location does not exist, create the path by making folders appropriately. Goto Products folder and copy firmware files from C6_firmware_for_Nokia_5800_RM-356(symbianzone.co.cc)' or 'C6_5800_RM-428(symbianzone.co.cc)'  and paste them inside RM-356 or RM-428 folder respectively.

15. Again enable 'Use INI' and select the same phone version it will show all files we copied now and the MCU, PPM and APE Variant lights on the top will glow green. CNT must be off. The box below will show the version you are going to flash as v51.

16. Make sure that your phone has enough charge and will not switch off in the next 15mts. Switch the phone off, connect USB cable to pc and phone and leave it. After switching off, insert your memory card.

17. Now everything is done, click on the 'FLASH' button the top right corner of JAF window. A warning box will pop up, dont get scared, its just a general notification, so click 'YES'. Now it will tell "PRESS POWER ON NOW! Searching for phone..."

18. Now press the phone's power button for 1 or 2 seconds to switch it on, dont keep holding it. You will not get a vibration as usual and the screen will go white. Check on JAF now and it will say phone found and erasing and flashing will start shortly.

19. Flashing takes 1 minute and then JAF will say Done after pooling the fone. The phone will restart and PC will get 3 beep sounds.

You can now remove usb cable and use your phone!! Enjoy the C6 firmware on 5800!!!
