We are under construction, but we have available a forum
where our team discuss about this new project.
Nokiaguru presents new page about how to modify and upgrade/downgrade phone software and How to change ringtones at your nokia phone modifying flash file, you can find this at new webpage http://gsmsearch.com/nokiaguru.
Send flashes that we can study. You can upload your flashes at NFree
Here you can check all info that we have discovered. We will try to update this page often, Anyway i recommend you that you use our discussion forum to make a new comment or question.
of 6210 Nokia Mobiles which can be also used for many other types of Nokia
Mobiles (esp. 3310)
can calculate all Eeprom/PMM/PPM Checksums and one MCU Checksum. There
are no other Checksums in Eeprom :0) Also it can change , calculate and
fix the Securitycode.
developed a software it's NFREE 1.2 prototype
If you use
my source code for your own work, all I only want is that you also publish
your source code. If you’re kidding on me, stealing my code or
progs out of it, there will be no fun for you anymore, believe me !
not to publish my new sourcecode because some guys were really lame and
thought they can use it for their own tools without referring to me.
infos about the Nokias :
can see on almost every Nokia Mobile :
Number is saved as plain hex and as a "security" imei, which
is the IMEI, xored with Hex 65
seems to be always the same. The old ones (51xx,61xx,31xx,32xx) have got
an eeprom and the new ones (62xx,82xx,33xx) have got an eeprom emulated.
Checksum in Eeprom is calculated by adding all hex char occuring in one
field before the checksum value. (at 51xx,61xx the first length of Checksumfield
is Hex 3E)
Nokia 6210 and i suppose many other new Nokia Mobiles :
Sectors : Here PMM :
F0F0FFF8000 = Sector Mark
2504D4D = "PMM"
00000000000006 = Don't know yet
0001 = Deactivated,
0000 for Activated
the base changes from 3FC000 to 3FA000 ... could not find a reason why
base address is saved.
If the base
is 3FC000 and the range is 200000-600000, version doesn't matter :
3FC0146-3FC279 Crc-Sum at 3FC27A-3FC27B
is 16 Bit from 0x200024 to 0x130101
MCU Checksum Field Start and Endadress is right after the Checksum (subtract base 0x200000)
: Changing the MCU does NOT lead to no network !!!!! This could be useful
for our Updateresearches.
PPM Checksum is 32 Bit (multiple values). Structure is Checksum (4 bytes) + Length of Field. Starts at Pbase+0x25f
: 00F44A000055FF00F00006D579303030303000 (Example is Securitycode)
Names from Adressbook are saved as Unicode (Names) and Numbers are hexed
with lobyte/hibyte 0xA for 0x0
*bad bad boys, what ya gonna do ....." : Snake 1 Index is : 770000
Nokia 3110 (thanks, koloksky) :
base vary from version
find block 2 crc length for 3310, for
(eeprom) it starts right after crc value
length (011d), block 2 checksum is at
Nokia 3310 (thanks to Executer, Schrifti and other Freaks giving me backups)
Same as 6210,
but MCU Checksum is at another place. Eeprom Base is usually 1E0000, MCU
Base is 130000
could harm your mobile, never forget :0)
can make a backup any nokia , please mail me !
find other values, or have any question, comments or suggestions, use
