Now I’m here to explain How to flashing Nokia 5800 using JAF with latest version 21.01.101. Flashing process can be done in three simple stages
Download Required stuff
Download all software’s mentioned below and Install them (Works only on Windows)
. NOKIA SUITE”
. Navifirm (To Download original firmwares)
JAF (A software which performs Flashing )
. OGM_JAF_PKEY_Emulator_v 5 (used to start JAF)
. JAF_ NOKI4MODELS.INI (This file included all Nokia Models)
.
Downloading Required Firmware
Before Downloading your phones firmware, check your current firmware version and Phone’s RM. This can be checked by dialing *#0000# from normal dialing pad
Now open Navifirm and wait until data loads. Now select your Phones model in products tab including RM and select firmware version you need to flash your mobile. (In this case Nokia 5800)
Download all files to C:Program Files/Nokia/Phoenix/Products/RM-XXX
Replace XXX with your phones RM. In my case my phone RM is 356 so, i created C:Program Files/Nokia/Phoenix/Products/RM-356. If this directory does not exists in your computer, create it manually
4. Be careful while selecting firmwares version. Always select higher version firmware. Flashing with lower versions may brick/damage your phone
NAV
So, Lets Flash your Mobile
Before flashing your phone, Backup important data like contacts, Messages etc
Replace/overwrite JAF_ NOKI4MODELS.INI file in C:Program Files/ODEON/JAF
Open OGM_JAF_PKEY_Emulator_v 5.exe and tick Random PKEY Raskal SN, JAF (main) and click GO. Wait for few seconds and an error popups notifying “BOX DRIVER NOT INSTALLED”, ignore it and click ok, JAF will startup automatically
JAF
When JAF starts navigate to BBS tab and tick Manual Flash, Normal flash, Dead USB and untick CRT 308. At last click use ini and wait for few seconds. Entire Nokia phone models would open in new window and select your phone exactly including RM (Most Important Step)
If everything goes fine MUC, PPM, CNT, APE Variant buttons turns green
Now, switch-off your mobile and connect to computer using Data cable
Click Flash, Ignore warning and click Yes
Flashing process would starts and shows a message PRESS POWER ON NOW. Now, press and hold Power button for just for one second
JAF 2
That’s it, take a cup of coffee and your computer do the remaining process.
Optional Steps
After flashing Nokia mobile 5800 or any other, Remove the phone’s battery and replace it again
Reset your mobile by dialing *#7370# to remove any bugs (if present)
Precautions
Never flash any mobile with lower version software
Charge your phone battery completely (at least up to 50%)
Never disconnect the mobile from computer while Flashing
DO THIS AT UR OWN RISK, POWERED BY HOPE TECHNOLOGY!
