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.

Hi,
Siemens SX56 Unlock
I would like to know if someone unlocked its phone by himself.
All we read is people from everywhere except with AT&T.
My ROM version: 3.14.03 ENG date: 09/27/02
Radio version 6.12 protocol 324e4
Frequency 900/1900 American model PW10B
Does the Rom Update 3.17 from xda-developers works with Rogers AT&T?
Can we expect our phone to live after that update?
Is the new ROM functionnalities user friendly? Would you rather keep the old ROM version both UNLOCKED?
If you got your SX56 unlocked, can you tell me what you did?
I'd like to have your comments on what you did before I do it.
After spending that kind of money, I wouldn't like to kill my phone.
So let me know how you did it and what did you need to update it.
I expect to get details from you.
Thanking you in advance!!!
The ROM has nothing to do with receiving the signal. It's the RSU part (Radio part of the device). ROM 3.17 should be fine with unlocking, but you may try this tool firls to keep your current ROM www.xda-developers.com\XDAunlock\
To determine the best RSU to use with your new network then you have to get some info about your device and the frequency of the network (900/1800 or 900/1900).
But ... get your XDA unlocked first then we'll see if it receives signal or not.
Good luck
I unlocked my Siemens SX56 from AT&T with the XDA Manipulator tool on this site. To use it, you need a serial cable for your SX56. I just made one. In reality, it would have been much easier to simply upgrade with the special edition ROM on this wedsite and use the unlock tool. The ROM upgrade should not effect the phone at all since it is the windows operating system and not the radio software (radio stack) which is a seperate upgradeable piece of software.
To be safe, just download your current ROM onto an SD card and then use a seperate SD card to upload the upgrade ROM. If you don't like the upgrade ROM, you can always restore the original ROM and the good news is that once your phone is unlocked, it's unlocked no matter what ROM you use.
Good luck, and upgrading ROM's using the SD method is really the safest way IMHO. You can find plenty of information describing the process on this site.

Hi,
I've managed to upgrade my MDA I with the new T-Mobile 2003 ROM Version: 4.01.16 ENG, Radio Version: 6.25.02
Any idea how I now unlock the thing so that I don't need to use a T-Mobile SIM?
I know I could install a different version of 2003, but I actually do want to use the T-Mobile one.
Cheers
Paul.
UPDATE: I now think that my problem is not that I have a sim lock, as it is not telling me that my O2 sim is not supported in this T-Mobile device. I think this may be an issue with the radio version. I have tried going back to my old 2002 install and also the XDA developers special. But no matter which one I install I always have the new radio version of 6.25. Does any one know how to "downgrade" my radio to an older one?
hey there i have a problem unlocking the SX56 its a ATT device witch i upgraded via the Siemens Website to the 2003 version,
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.

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

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!
Hello,
How are you?
After finally managing to unlock my xda, it does not find any networks!
My ROM Version is 4.01.12 ENG
ROM date 12/22/03
Radio Version 6.24.00
Protocol version 324e4
Does anyone know of this problem?
Please help me.. I was so happy to unlock it and now i have run into this problem....
I have read that you shouldn't play with the gsm menu in the bootloader screen.. well i did play with them before i knew i shouldn't. Could this be the problem?
Is there a way to reset it?
Should I go to a different radio version?
Please help,
I live in France and I am on the french bouygtel network. I believe this is a 900/1800 gsm network.
Thank you,
monza

6.24.00 radio is for PWA10B1 and for 900/1900 networks only (for USA).
If you have a PWA10A1 model (check the back of your PDA), you should use 4.21.00 for 900/1800. Note: upgrading Radio Stack is very risky, do it for your own responsibility! So after you downgraded to 4.21, enter bootloader, press calendar button then select "900/1800" and soft reset.
You can get 4.21 radio stack from here:
http://lumpistefan.dyndns.org/tools/RSU_V4.21_PPC.zip for the ppc install version and
http://lumpistefan.dyndns.org/tools/RSU_V4.21.zip for the activesync version. I remind you, upgrading radio stack is risky!!
Search in the forums how to upgrade radio stack.
Oh, and entering bootloader makes a hard reset.

Compatibility of SEROM with Radio A.20.10
I had been asking a similar question elsewhere in the forum.
Given these device specs,
ROM Version : A.21.02 ENG
ROM date: 10/17/03
Radio Version : A.20.10
Protocol version : 324e4
Carrier : AT&T GSM/GPRS in the USA,
would you know if the version of the Special Edition ROM v1.2 available on this site (http://wiki.xda-developers.com/wiki/SpecialEditionROM) should be compatible with this radio stack or not? I would not want to do a RS up/downgrade if I can avoid it.

Using a T-Mobile on European GSM
I've just acquired a T-Mobile (unlocked) and want to use it in New Zealand, which has a European setting, 900/1800. The T-Mobile is a PW10B1, which I think is setup to operate on a different frequency.
Can I swap the radio stack to operate on my local GSM network, or will I fry the PDA.
If I do swap the radio stack, and it fails - is there a ROM which I can use to rebuild the PDA with instructions on how to do this (URLS and links would be VERY much appreciated!)
Thanks, Hamish

PWA10B1 is for 900/1900 ONLY. You cant swap radio strack - if your provider works on 900 mhz, then you have to use it on that freq.
T-Mobile in NZ (from Canada)
Thanks for the reply.
Since then, I've installed a v4 radio stack (as described earlier in this thread) and the system does boot, but won't see my PC for Active Sync and also won't see the network.
I'm downloading the official T-Mobile ROM which I hope I can use, but if activesync won't work, any suggestions as to how to get the ROM loaded?
Also, is there a utility to select the network bandwidth, as there wasn't one already on the device - and I'm beginning to get a little concerned now!
Many thanks for your time so far!

You can choose 900/1800 or 900/1900 from the bootloader, press/hold power while pushing reset with stylus, then when screen appears, push the button below the antenna, choose your appropriate band and from there, for model A choose 900/1800 for model B choose 900/1900. Make sure you have a working backup of your data when using this method.
Using a T-Mobile on European GSM
Thanks for your help.....I managed to get it into bootloader, but was pressing the contacts button (left) rather than the right (calendar).
I now have managed to get the device to see the local 900MHz network, so it's functioning !
Your help has been much appreciated!

I just got a tmobile sx 56 off ebay. It's locked! Even though they said it wasn't. I am new to all this so my question is if I unlock with xda special rom and then cook my own 2003 rom on http://lumpistefan.dyndns.org/
will my phone remain unlocked. I need to use it on cingular network. Do you think this will be an issue. its gsm and all that jazz.
Any thoughts are appreciated.
it'll stay locked
and this is a gsm phone so it'll work with any gsm provider. im using the AT&T phone on the t-mobile network
got the code from tmobile..so now it is unlocked. Now I'm looking to update to 2003. But alas I am a mac faithful. Is there anyway for me to do this. I move files back and forth using pocketmac?
