S56 unlock help - GSM-Forum

ericdkauff · 04-04-2005, 20:22

I'm a relative newbie, but I've tried to do my reading on how to unlock this phone. Here's what I've learned so far:

I've got a S56 from AT&T Wireless that I want to use a Cingular SIM in.

1) I've got an unlock cable (serial) that I ordered from a vendor on EBay (hoping its reliable)

2) I'll be using Freia v15, using the S55 as the phone option in Freia.

3) I'll choose Bootcore bug as my bootoption in Freia

4) I'll keep RTS and DTR checked on my COM port options

5) I'll set my COM port accordingly for the Serial port that the cable plugs into

6) I'll backup my battery parameters

7) I'll create a log from the phone

8) I'll create a map from the log that I create

9) I'll do a direct unlock with no map saved

Is that all that I need to do? Am I missing any steps? Should I also read the firmware flash from the phone? Should I read the EEPROM from the phone? What about the Bootcore?

I guess I just want somebody to tell me if I'm missing any steps, or if my steps are in the right order. All help will be sincerely appreciated!

7) You'll read a backup of firmware (FUBU)

8) You'll make direct unlock also map is saved

9) doesn't exist anymore

1-6 is ok, 7-9 make my steps

That will be the savest way you can choose!

How do I make a backup of my firmware? Can that be done through Freia, or do I need another application? The rest I definitely understand.

Thanks a ton!

Of course can that also done with freia:

Read-->Firmware-->ok-->press power on shortly

Awesome - thank you for the help!

One other question. My S56 has SW-version 06, with variant A 170. Have there been any reports of problems using Freia under those conditions? I'm just hoping that I don't have such an old version that Freia won't know how to work with it.

Version of phone doesn't matter for freia!

Freia does his job in EEPROM area (SimLock is in EEPROM stored) which is independent from firmware.

Worked like a charm! Phone unlocked & happy! Thanks for the help.
