Unlock PPC2003

[Raptor]

I have searched this site (fantastic site BTW) but see a lot of conflicting statements (or at least it seems that way).

I have a TMobile MDA-I (US) PPC2003
ROM version: 4.01.16.ENG
ROM date: 02/04/04
Radio version: 6.25.02
Protocol version: 324e4

I want to keep 2003 but need to unlock the SIM. Is this possible and where is the information?

you need to "downgrade" to the SER ROM, unlock your machine, and then Restore back your ROM, or upgrade it to something else

What is the SER ROM?
what vresion to I have to downgrade it to?
Where would I find the software and exact steps?
Are they any issue with doing this?

www.xda-developers.com/SER/

or just try the unlock tool at www.xda-developers.com/XDAunlock/

All you have to do is call T Mobile USA's Customer Care and just tell the CSR you're going to be travelling overseas and will be using a prepaid SIM from one of the local wireless carriers over there. The CSR should be able to provide you with the unlock code provided you've had continuous wireless service with them for a minimum of 90 days and your wireless account is financially current. Cheers!

Thanks all, I like the overseas idea. Any hints as to places to travel where this is possible. I don't want to say I am going to the Bahamas (example) and have them tell me that the phone will not work there anyway. :oops:

I installed the SER and I'm still locked ("error finding unlock code"). Any ideas.

Radio Stack 6.25

SER ROM and XDAunlock or Manipulator cannot work under radio stack 6.25 (T-mobile USA) or A33 (Siemens AT&T).
I developed new tools to unlock them!
:wink:

Cgigate, have you posted the new tools to unlock that version of radio stack? Also is there any way of using xda manipulator imei feature under radiostack 4.21 as it is disabled one it meets this radio stack, I assume the developers have good reason for doing so.

I cannot test radiostack 4.21 or any 4.xx (GSM 900/1800)(PW10B1).
I'm Canada , same as US, GSM system is GSM 1900.
I'm using GSM 900/1900 version (PW10B1)
