Unlock PPC2003

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/

Unlocking a T Mobile USA Pocket PC Phone Edition
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.

Same Issue on PPC2003
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.

Taimur, I dont mind answering personal messages and I understand your reticence to mess with an expensive purchase without knowledge of all the downfalls, it is better to ask before a problem arises than after. Glad to have helped and I hope you enjoy using your new tool.

now when i use the tool xdaunlock i always get an error:
error getting unlock code
anyone has some help on that
here is the info
ROM Version: A.30.09 ENG
ROM date: 01/01/04
Radio Version: A.33.02
Protocol Version: 1.3.3
Model: PW10B1
please help me !!!

XDAunlock tool doesn't work with WM2003 ... you have to down grade your ROM to PPC2002 ... try to cook any 3.17 based ROM from the kitchen here and it's better to flash your ROM with the SER v1.2 which will ulock your xda with the first reboot

thx for the info
would you have some info what SER 1.2 is or some step by step instructions

GSM Band change
Hi,
I have an unlocked AT&T Siemens XDA I :
ROM : A.30.09 ENG
ROM date: 01/01/04
Radio : A.20.10
Protocol version: 324e4
Under Settings>phone> i cannot find the tab found in other versions where I can switch the GSM band between 900 and 1900.
what should I do about that? is there anyway to switch band? or do I have to upgrade/downgrade the OS?
The phone is working with both T-mobile and AT&T networks, but I will need to use it in Europe and Egypt (Vodafone).
hey Biso007 , I hope you have the answer
thank you

Band Switching in Windows Mobile
The tab used to switch the bandwidth, 900/1900 MHz GSM, was removed in Windows Mobile as the software interface with the radio stack unit/RSU automatically will switch from the Americas' 1900 MHz to the international 900 MHz and vice verse when travelling to other countries. My friend has an unlocked Siemens SX56 Pocket PC Phone with AT&T Wireless(hopefully soon to be Cingular Wireless) as the service provider, took the SX56 over to Ireland with him on a business trip and used a prepaid SIM without any problems.

Band switching
Hey
Thanks for this information.

As raycaroll70 said, band switching is being done automatic between 900 and 1900 for B devices, and 900 to 1800 for A devices ... this is true in A30.0x ROMs from AT&T
In T-mobile ROMs it's still being done through the phone settings but only for B devices 900/1900. It's also worthy to be mentioned that the RSU is a significant factor in this issue ... I think A20.x does this auto switching, but I didn't try it with 6.2x.0x RSUs

SER v1.2 cannot unlock WM2003 version radio stack 6.25 or A33.
The SER V1.2 is absolutely obsolete.

Thx for this already known info, but I expect the people coming to this forum for "FREE" advices ... then if it doesn't help they can seek a help with a charge if needed.
Note: even if SER v1.2 is obsolete (which is not true!), no one said it should be kept to be used as the final ROM (even tho it's still working fine) ... it's just a transitional state for unlocking ... and for the RSU issue, many people here down graded the RSU then unlock then upgrade back to a recent RSU ... and they did it with no charge as well

Downgrade Radio stack is big risk!
Many XDAs are dead cause radio stack downgrade/upgrade failure!

New Siemens SX 56 ! How to unlock ?

My device information :
Siemens SX56
ROM : A.30.09 ENG
ROM date : 01/01/04
Radio version : 4.21.00
I've read all the topic here, but nothing can't apply to unlock my Pocket PC. Can anyone help me with this ?
Thanks so much.

you can't unlock it while you have any WM2003 ROM ... you must down grade to PPC2002 ... SER v1.2 is good for that.

So can't have any solutions to unlock it ?
Cause I doesn't want to downgrade it, it's not a good way to unlock.

down grade, unlock then upgrade again

Hi,
I'm new on this forum and I see that there are very knowledgeable about the at&t siemens sx56. I just purchased one, and I intend to use it with my t-mobile service. It is un-locked with the at&t logo but I would like to sign up for e-mail and internet with t-mobile using this phone. Do I need to update/change the ROM as I've been reading on this forum, and how do I change the ROM to a t-mobile? I would also like to know all he things I need to do to make it run wih T-mobile services. Thanks in advance.

There is no need to change the rom, you can manually enter all the settings for your services once you have them from your service provider or from this forum.

cahnging service provider
thanks, how do I change the settings from At&t to the t-mobile setting. t-mobile will not give me any instructions since the sx56 is for at&t. I would appreciate it if you can provide me the setting or point me in the right direction. Thanks.

First, spend some time reading in this forum and use the search option ... then go to the kitchen and cook 3.17 based ROM ... flash your ROM which will be unlocked by that time ... then cook any other WM2003 ROM to upgrade your xda ... 4.01.16 is very good option

big problem help please

hello i have an big problem my wallaby dont connect to the phone network so i can't use the phone
please can someone help me i live in the netherlands my operator is tmobile
my rom version is 4.01.16 ENG
rom date 02.04.04
radio version 6.24.00
protocol version 324e4
is this wrong??
please help
greeting cor

Try entering bootloader, power switch held down while pushing stylus in reset, then push the button below the antenna, then choose 900/1800. You will need to do a backup first.

Your rom versions show that it is PW10B1 version (north american version GSM 900/1900).
If your local SP provides GSM 900 service, switch the band to GSM 900 (Setting > phone > Band > choose GSM 900

i have set the gsm band to 900 but it won't help he is stil searching for network
does someone have another solution???

There is another possibility, your phone is PW10A1, but the firmware and radio stack had been "upgraded" to PW10B1. So you won’t get any signal.
Check the label on back to see it is PW10B1 or PW10A1.

yes you are right that is it but where can i find the good stuff

so i must change my hardware version to pw10a1
any idea how i can change that??

now i have tries to update it via asimagetools
but i get a message
itsdcardinfo:niet nader omschreven fout

Well, my device is PW10A1, but when i had T-Mobile 4.01.16 rom on my xda, it said PW10B1. Therefore check the back of your xda, if it says PW10A1 then you HAVE that version, just the rom says not. hehe. About flashing: you can not use programme a to flash your XDA when you have an T-mobile rom on it; you can only flash it with the SD-card method (use forum search). Try to flash in an 4.01.12 version (O2), i found it better than the T-mobile one.

massage for cgigate and stefan
