[GUIDE] Making and flashing your CFW for S^3 devices

[NikShiP]

Here is a short tutorial for modding and flashing S^3 phones using Nokia N8 as reference

First of all the tools needed for cfw are :

1.  NaviFirm+ by Il.Socio - DOWNLOAD

2.  Nokia Cooker by Il.Socio - DOWNLOAD

3.  NFE Core 2 (English) by doctorly - DOWNLOAD

4.  Phoenix (2011.14.004.45945) - DOWNLOAD

WARNING : FIRMWARE MODDING AND FLASHING IS NOT COVERED BY WARRANTY AND IS VERY RISKY, SO PLEASE PROCEED AT YOUR OWN RISK

I'VE TRIED MY BEST TO MAKE THIS GUIDE AS SIMPLE AND ACCURATE AS POSSIBLE, BUT IF ANY MISTAKE IS FOUND PLEASE CORRECT ME

ANY SUGGESTIONS ARE MORE THAN WELCOME

FIRST STEP

Download the firmware files using NaviFirm+

Open NaviFirm+

#1 Make sure that "Nokia Care Suite" has been selected as the "Server"

#2 Select the "Product"

#3 Select the "Release"

#4 Select the "Variant"

#5 Make sure "Parse VPL" has been ticked and then verify that all necessary fw files are selected for download

#6 Select the "Files". The needed files are : core, rofs2, rofs3, uda, dcp, vpl, bin (uda must be ticked manually). You may also download the "Memory card Content" if you want the preloaded content.

#7 Then click on "Download from FiRe" to download directly or copy the URLs and download them manually

After download is complete, make a backup of all the downloaded files in a safe place should anything go wrong with modding and flashing. Later on these original files can be used to re-flash the phone if needed.

SECOND STEP

Edit the fw files using Nokia Cooker (The backup files should not be used for editing)

Open Nokia Cooker

#1 Open the required file by clicking on "Open Firmware" (Only rofs2, rofs3 and uda can be edited using Nokia Cooker)

Alternatively you can just drag the required file to the left pane named "Custom Firmwares"

#2 A couple of seconds later the right pane will display the firmware file contents. Now drag and drop the mods u need in this pane

#3 When finished adding mods and making changes click on the "Save Firmware" button

#4 The bottom pane will display the log since the opening of the file

The firmware will be repacked in the original folder and the original files will now have a suffix "_BACKUP_" in it

Repeat the steps for the other files if needed (i used the rofs2, so if needed changes can be made to rofs3 and uda in the same manner)

THIRD STEP

Calibrate the core using NFE Core 2 (Many many thanks to nicesoni_ash, without him i would've been stuck with a dead phone after flash with modded rofs files)

Open NFE Core 2

#1 Click on the "Open" button and select the core file to be calibrated

#2 After the file is initialized click on the "ROFS calibration" button

#3 A popup window appears, change all values to "2C"

#4 Click on "Apply"

#5 Click on "Exit"

Nothing else needs to be done in the core file

FOURTH STEP

Flashing the phone with the modded files using Phoenix (Thanks to nicesoni_ash again, this procedure is entirely based on his method as he posted as a document)

IMPORTANT

#1 BEFORE FLASHING, EVERY IMPORTANT DATA FROM THE PHONE SHOULD BE BACKED UP

#2 THE MASS STORAGE CONTENT SHOULD BE BACKED UP TOO, AND IT SHOULD BE FORMATTED

#3 IF NOT FORMATTED DELETE THE SYSTEM FOLDERS FROM MASS STORAGE

#4 THE PHONE SHOULD BE SWITCHED OFF BEFORE STARTING FLASH

#5 PHONE SHOULD NOT BE CONNECTED TO COMPUTER UNLESS INSTRUCTED BY THE FLASHING SOFTWARE

Open Phoenix

Now follow the pictorial instructions

[img width=672 height=420]

Now bring all the original downloaded firmware files into the above mentioned folder

To do this, create a folder named "RM-xxx" inside the above mentioned folder, where xxx is the device's number, and paste the files inside this folder

According to the example the files should be in this folder now - "C:\Program Files\Nokia\Phoenix\RM-xxx\"

Now follow the rest of the guide...

Just don't use NFE core... it is not needed anymore. You can unlock the ROFS using lastest versions of NokiaCooker.
