Update: Leaked Symbian Belle PR 3.0 Firmware with Revamped User Interface for Nokia N8 is now available over here.

This Tutorial is definitely a complex one, for your ease we have now posted Dr Web hacking solution for Symbian^3 / Symbian^4 by following this guide over here. (One Click hacking may only work if you have your cert n key, though these days you’ll not be able to get cert n key anywhere on the internet, due to restrictions laid by Symbian Signed)

a. Flash at your own risk, we bear no responsibility for any problem(s) occurring to your device due to flashing…
b. Uninstalling is only possible after the first Restart of phone!
c. The internal file manager does not show the system folder (have deliberately left out)
d. This flashing process has been tested on Win XP 32 bit and Windows 7 32 Bit
e. Its better to turn off antivirus while flashing
f. Press *#0000# to see your Product Code
g. In photos, RM-596 FW is taken as an example, u can take any Symbian device and firmware
h. and make sure you are not downgrading i.e flashing the lower version than the current device version (It will make your phone dead) (For instance you have firmware version 14.2 and you are flashing with firmware version 13.1, in that case you will brick your phone)
i. make sure you are not flashing an edited rofs2 or rofs3… (You have to use overwrite trick for flashing with hacked UDA, more details are mentioned at Step no 10)

Basic requirements:

i.) Download NaviFirm from here and Pheonix from here

ii.) Open NaviFirm which u downloaded from the above link, select your device + product code [see note f] and download the following 9 files (while downloading, focus on the extensions, which I have mentioned in bold letters below and keep an extra backup of these Original Files):
1. 0x0-0xxxx0_Pxxxx_00x.xml (Type Label Configuration)
2. 0xxxx0vx.pcx (Type Label Picture)
3. RM-xxx_014.002_14.0x_xxx_x_79.92_prd.rofs2.fpsx
4. RM-xxx_014.002_79.92_prd.core.fpsx
5. RM-xxx_014.002_Cxx.xx_xxx_1_xxx_79.92_prd.rofs3.fpsx
6. RM-xxx_014.002_Uxx.xx_79.92_prd.uda.fpsx (Content)
7. RM-xxx_0xxxxxx_014.002_00x.dcp
8. RM-xxx_0xxxxxx_014.002_00x.vpl
9. RM-xxx_0xxxxxx_014.002_00x_signature.bin

Sometimes it may not show you the 9 files which is mentioned above and may show only 6 files… In this case try to switch between the Nokia Care and Product External, as sometimes one of these source will have full files… See an example below for understanding:

iii.) Turn off your Antivirus, install the Pheonix which u have downloaded from the above link and restart ur system…

Now u r ready for flashing, follow the brief steps below CAREFULLY to avoid frustration and problems…

Brief steps of flashing to solve the crc checksum error:

1. Rename the provided uda file to your uda file name ‘RM-xxx_014.002_U0x.0x_xx.xx_prd.uda.fpsx’
2. Copy paste the original 9 firmware files which u have downloaded through NaviFirm to C:/Program Files/Nokia/Phoenix/Products/RM-xxx/
3. Connect ur device (C7/N8/E7/xx) through Ovi Suite and wait if any drivers’ installation is in progress
4. When driver installation in done and it shows that drivers are up-to-date, then execute Phoenix (better right click and run as administrator)

6. Go to File > Scan Product > and wait until the bottom bar of the phoenix says ready and will display your phone’s connection

9. There will be a warning about the file is not complete / missing bla..bla..bla.. (this step is important)

10. This is very important!!! Don’t press anything in Pheonix yet and go to the provided hacked uda!
11. Copy paste the provided CFW / hacked UDA file (that has been renamed) to C:/Program Files/Nokia/Phoenix/Products/RM-xxx/ and overwrite it. If its not over written, probably you have to rename it according to the original firmware UDA.
12. Now come back to Phoenix and press ‘YES’…

Now your Nokia N8 has been hacked with Random User’s Custom Firmware. You can easily install unsigned Applications which used to give annoying certificate errors. Rom Patcher v3.0 can now be installed on your Phone. You can also disable the Call Recording Beep using Rom Patcher.

What if your Nokia N8 becomes Dead after following this procedure? Don’t worry still you can recover back using Dead USB mode in Phoenix. All you have to do is to follow the simple steps mentioned here.
