TroubleShootings

Finally our camarade Dejan has designed a new low cost device which can flash nokia mobile phones, now you don't need to spend 20.000 US $ in a TDF-4 box. The nokia flasher use is not dificult to use but you must be attent at every step you do. Once time you make fisrts time it will be a children game, you can flash any nokia phone in just 7 seconds.

There is two ways to flash with Dejan Nokia Flasher, Full or partially.

1. Partial Flash: is used to unlock and always should be used the same sw version file as you have in your mobile phone. This files have 64 Kb. This process take just 7 seconds.

2. Full flash: is used to unlock, repair broken phones or change phone language. Flash memory is fully changed with this procedure, EEPROM should be programmed too, but sometimes is suficient just only programming flash memory, if mobile phone not have coverage later you have flashed you must program EEPROM too, flash and eeprom files must have same sw version and language. To write or program EEPROM memory is necesary an SMD EEPROM programmer with SOIC clips (available at ucables.com from February, 2001). Flashing process can take between 1 and 3 minutes. Size of flashing files are between 500 and 1400Kb. The difference to make a full flash or make a partial flash is to used different flash files and range of addresses.If you don't need to change language, we recommend you use a partial flashing. If you really need full flashing, the best way to do it is to get another unlocked mobile phone of the same version and read flash in the appropiate address range and read eeprom. Later you must write flash and EEPROM to the phone that you want to make full flashing. New nokia models 3310, 8210 and 6210 is not necessary to reprogram EEPROM because EEPROM memoria not exist, it's stored at the FLASH.

When you make a flash you must take in mind 4 parameters, mobile phone model, phone software version (sw), flash memory type (INTEL, ATMEL, INTEL 28F160) and start address where to start to flash. First thing you must do is select the type of memory, you can choose INTEL, but if you try and it not works you can try the with ATMEL or INTEL 28F160.

To make this process easier we will explain how to flash using a Nokia flasher shell 1.5, it's a program that interface with the original MSDOS program Nokia Flasher 1.0b and it allow to select, flash type and sw version. Nokia flasher shell will show us appropiate start addresses that we must enter at nokia flasher.

Requirements:

1. NK-FLASH cable, available at http://ucables.com
2. SMD EEPROM programmercon with SOIC clips (required for full flashing only)
3. Nokia Flasher Shell + Nokia Flash 1.0b by Dejan
4. Partial flash files (included)
   
   

Steps to programming a partial flash file using a NK-FLASH cable

b) Unzip in the root directory c:\

The file ucables_flasher_shell_12.zip contains new ucables.com flasher shell, Nokia flasher 1.0b by Dejan, partiall flash files (.fls), and all .tia and required configuration files. If you need full flash files to repair or change languages you can find here.
Anyway you can always read full flash from an unlocked phone and dump it at the phone that you want to repair. Be sure that have same software versions, if you don't use the same software version checksums are differents and it will not work, take care you can damage your mobile phone!, at the moment we are procedure to flash with different mobile phone versions, if you don't matter to crash any phone, you can try to do this and later use Wintesla with appropiate libraries to fix coverage.

2. Check sw version of nokia mobile phone

You can read sw version pressing *#0000# (phone must be turned on and with a simcard inside), or you can read it using Nokia tool with the cable NK-567

3. Execute uCables Nokia Flasher Shell under MSDOS
We have make a new fast and easy to use flasher shell for Nokia flasher, it's easily upgradeable to support new sw nokia versions. If you have got new .fls flash files you only must copy to the c:\nk_files\partial directory and write .txt with start address. By example when we have added new file 3310-418.fls we have created 3310-418.txt writing the start flash address 280000.

a) If you a have windows run a msdos box, From Windows Press Start menu, select Run, write cmd and press enter.
b) Go to flasher directory and run flash.com program with appropiate parameters.

Command line options:

1 = INTELW 8	2 = AMD 8	3 = INTEL 16
4 = INTELW 16	5 = ATMEL 16	6 = ST 32

Troubleshootings

1. I Have selected the right flash type and start address but Nokia flash give me error: BOOT TX data error
a) Try different flash types from 1 to 6. You must try TO READ pressing F1 from Dejan flasher to check connection is working.
b) Don't use Nokia Flasher in a notebook, Paralel port not works not works like in computer desk.
c) Configure BIOS Paralel port with different modes EPP or SPP, etc. SPP should works.
d) Try in another computer may be configuration is not good

2. I need to partial flash new nokia mobile phones sw version like Nokia 7110 version 5.XX, where can i get new partial files for this phones and initial flash addresses?
Please be patient, we are working hard collecting and checking new partial flash files, our faq will be updated often and you will find new partial files here every month. Anyway you can try to read partial flash using same range addresses as in the previous version and try if it works, but you must do that making a full flash backup copy of your nokia phone. Once time you have done full backup you can try to read 3A0000 to 3AFFFF and write it to your nokia 7110, if not works you must restore your full flash backup and try again with a new range by example from 3B0000 to 3BFFFF.

Before to start to flash you nokia phone it's you must make a backup of your nokia phone reading the full flash or your nokia phone from appropiate flash addresses that you can check at our list depend on your nokia sw version

If you have an unlocked new version 100% working of nokia not included at our list. Please contact by email with nokiaguru@ucables.com and we will tell you appropiate start and end address.
