Hello
Here's an Italian boy

My Nokia 3330 mobile on sudden reports on display CONTACT SERVICES.
It hasn't got water. I think it would need to reload the firmware so I wish to have the working electrical schemes and PCB.

Thanks in advance for the help.

to flash the phone you need both a mbus and a fbus cable the mbus ( connects toi the lpt port ) to flash the phone and a fbus ( connects to serial port ) to update the faid when done.

NO NO NO

Both MBUS and FBUS are used to transmit data between phone and other device (computer). The first uses same channel to transmit and receive data and second uses separate ways and therefore it's faster . They both use the COM port to communicate with phone.
It's with MBUS that you unlock, change IMEI, and update FAID.

To flash a phone you need a flasher cable that connects to the LPT port. This is know as dejan interface and needs a flasher program to load firmware into the phone (Rolis, Knok, Geoflash, etc...)

Check the FAQ's page 'cause you get all sort of tutors that can lead you in the right direction


Cheers and enjoy the ride in GSM world :)

I've already the flasher schemas (which is standard) and I'm actually working on it.
as far I know there are a lot of MBUS
my previous schemas was the right choice to flash FAID?

it's good for the FAID (and unlock, IMEI, tones) procedure but use the flash expression only when talking about LPT cable and uploading firmware into the flash chip :wink:

Does this project work with fbus by maestro for reset security code on dct4?

definitely yes! pure FBUS cable works 100% with FBUS by maestro for DCT4 phones!

Hallo indicdican,

Does you look my attached files?
It's pure mbus, and non fbus.

Confirm your response?

yes! i have looked at your attached schematics, and it looks like it is Auto-Switch Mbus/Fbus cable, because you can see the pin outs of 1) FBUS-TX, 2)FBUS-RX, 3)MBUS, 4)GND....

on FBUS mode, the pins that are active: 1) FBUS-TX, 2)FBUS-RX, 3)GND

on MBUS mode, active pins are: 1)MBUS, 2)GND

best regards and good luck!!!!!

looking at your diagram i saw that the pin out marked itīs for a 51xx.
iīve made that circuit and itīs seems not to work in that model.
but if you have better news please let us know as soon as posible.

good luck!!!!
