Unlocking my SX56 Wallaby

[TomMonger]

I've been reading through many posts and have become more and more confused. Basically, I'm looking for the simplest way to unlock the subsidy code on my SX56. I don't know the best method because my ROM and Radio versions don't seem to match anything posted here.

My info is as follows:

Model: PW10B1
ROM Version: A.30.09 ENG
ROM Date: 01/01/04
Radio Version: A.33.02
Protocol Version: 1.3.3

Microsoft Pocket PC Version 4.20.0 (build 13349), which I assume is Windows Mobile 2003.

I really dont' want to change over my entire ROM because this one is working very well (even the radio portion). Siemens refers me to Cingular (formerly AT&T), and AT&T won't give me the code.

Thanks for any help!

I had your problem the week before last: There should be a way of telling someone what your IMEI number is and have them give you an unlock code but there isn't.

Just flash your ROM with the better one available here: Don't bother with the simple unlock utility available here because it probably wont run on your unit (it didn't on mine)

What do you care if your ROM is working properly if these people have designed a better one? Surely your only care should be how much you should donate to to them for developing it and then get it and unlock your unit?

And there will be the, - incalculable, - added benefit of doing one in the eye to Cingular who refused to assist you? (and, I am reliably informed, wouldnt assist you, even so far as to get THEIR phone working abroad, even if you WERE a customer of theirs)

If you want to stay at your current ROM Version, you coud make a backup from your ROM, flash the XDA-Developers ROM 1.2 to unlock your device and reflash you Backuped ROM.

I think your Radio Stack should work, so it isn´t necessary to change it.

THANK YOU, GUYS!!

I did a complete data backup and managed to save my existing ROM data to an SD card. I then performed the Special Edition ROM upgrade and it worked BEAUTIFULLY! And it successfully unlocked the unit :) This is a big deal to me because I was very afraid because of a disaster I had a little over a year ago.

You see, when I first got this Wallaby, it was equipped with PPC2002. After a couple of months, AT&T offered the WM2003 upgrade through Siemens. I made the mistake if upgrading,and found that the radio reception was deplorable. When I called to complain, I was told AT&T no longer supported these units. Siemens was of no help, either. (It was no big surprise that AT&T/Siemens yanked the upgrade so soon from their web sites!!)

That's when I found this site. I decided to try to replace my radio stack to its original version. I was one of those people who got the 1% problem and my Wallaby had become a shiny, silver "brick". I was going to dump it, but decided to try and see if I could get it fixed (or reflashed) through AT&T or Siemens. AT&T wouldn't do anything. They basically told me, "Sorry, your 90 days is over and we no longer support the SX-56 units." I then called Siemens and to my ASTONISHMENT, Siemens agreed to fix the unit because it was just under a year since I had purchased it! When I sent them my "brick", they sent me back a newly refurbished unit... complete with WM2003 *and* a good radio stack! So, you can see why I was afraid to try and unlock this thing!


Anyway, after performing the Special Edition ROM upgrade, I tested a different provider's SIM card (TMobile). It worked fine :) I then flashed the unit back to my previous ROM (WM2003) without incident and successfully restored the data. The unit is still unlocked and working quite well!

Thanks again! This is an awesome site for XDA enthusiasts!
