I recently got a locked SX56 loaded with the 2003 ROM. To unlock it, I flashed it with the SER and it's working fine now. But I'd like to go back to the 2003 ROM yet keep my phone unlocked.
Before flashing I had backed up the 2003 ROM using XDATools, can i reflash that image into the sx56? Would this keep my phone unlocked? OR do I need to download the 2003 ROM from the Siemens website (really do not want to dl 18 mb!).
Any help is highly appreciated.
Thanks
Omi
You can reflash your backup version. The phone will be unlocked after upfrading...

not able to change bands
Thanks LumpiStefan for your reply, I hope you could also help me with another problem that I'm facing with my XDA.
After changing to the SER, I wanted to switch bands also to 900/1800 but when the I start the band selector tool it gives an ERROR everytime and I'm not able to change bands. It works fine with the operators on 900Mhz but unfortunatley the operator who provides at 1800Mhz is much cheaper and also provides cheap GPRS services here. I'd really like to try the phone on 1800Mhz to see if it would be possible to use the phone with that operator.
Would changing to WM2003 help me change bands easier?
Thanks
Omitav
It all depends on the device type ... only PW10A devices work with 900/1800 (check the rear sticker) ... also the RSU must be suitable for 900/1800 or you may endup killing the device!
Hi Biso007
I've read in the forum that several ppl have changed bands in their PW10Bs and been able to receive 1800 operators (altough the signal strength was usually bad). I wanted to try that out.
How do I find out if my RSU supports 1800 Mhz?
The device info mentions that my Radio is A.33.02, can (and should this) be upgraded?
Thanks for your help.

I think you mean that some B devices worked on 1800 operator network and this can be true if the operator supports 900 as well (usually they are) and that's exactly my case.
I don't think B device with 900/1900 RSU like yours can work on pure 1800 MHz network ... or what is the need for the expensive tri-band XDA II then :wink:
Right, I got it
Yep, mine works fine with the first 3 operators in the state (since they're all on 900). It only won't work with the 4th operator (hutch) as they're on 1800.
Can't have everything I guess :-(
Hutch provides really affordable GPRS, gonna miss that. The other operator provides GPRS at exhorbitant rates, will have to wait until some operator gives at a cheaper rate.
BTW, where r u located in India ?

I have managed to unlock my sx 56 from at&t using xda's software. Great. Trouble is it only enabled me to use O2 in the UK, i then went to yorch.net and downloaded more software which enabled vodafone and O2. Better. But I was wondering how I could unlock it so all networks worked. Can anyone give me a hand?

What you'll find is that there were two versions of the XDA (AKA...). One which was sold in Europe and ran on 900 and 1800Mhz frequencies, and one which ran on 900 and 1900Mhz frequencies, and was sold in the US (SX56, MDA, etc).
You may or may not know that Orange UK runs solely on 1800Mhz (as does T-Mobile), and as such you'll find your version to be incompatible with these networks... Sorry.
Although this device is from the states, I have found the option of using it oat 900 gsm or 900 / 1800 gsm or solely 1800 gsm. Does this mean that I may be able to use orange ?

Although it might give you this option, I believe that the radio hardware inside it is designed only for 900/1900mhz. I guess you could try and put an Orange SIM in, in an area where you know there to be coverage, and see if it works. It is unlikely to work on Orange or T-Mobile.
Let us know either way, cheers
I have tried my sim in an area I know there to be coverage. It just comes up as no signal. Since going through the site I'm thinking of getting a serial cable and using manipulator although its a little ambiguous about whether this will work. One company reckons they can do it but if what you say is correct then they'll be waisting their time and my money.
It might be easier to swap providers!
Beini, if your phone is 900/1900 it will not work on Orange which is 1800.
O2 XDA RUNNING ON ORANGE NETWORK FINE NO CONNECT TO INTERNET
Thanks guys for showing me how unlock my 02 XDA so I can phone out. But I just cant get it to connect to the internet - can anyone help me?
I dont have the option for 1800 (Baud Rate)
i suppose the getting access to the internet is going to be impossible...??
How do I configure it to atleast work for WAP?
Hi,
is it possible to make the sx56 or tmobile ppc phone (normally 900/1900) work on the european 1800 mhz networks as well :?:
Thank you
Yes, you need to change it in the bootloader. Just select the one that has got the band you need. Don't try to change it in the phone settings, or it won't work.
Are you sure ?
I tried what you mention and it does not connect to Telstra...
I am running a 6.25 radio and an 4.01.16 TMO rom with a 5.17 bootloader.
I tried both 900 stand alone and 900/1800 but it did not work.
Any other trick ?
Thanks,
Bob.
so, has anyone ever succeeded with activating the 1800 mhz?
It's all depending on the device type ... PW10A works only for 900/1800 ... and PW10B works only for 900/1900 .... don't try the impossible!!! ... or you may permanently damage the RSU part!!!
better to get XDA II ... it's tri-band
well, I'm planning to buy one on ebay. how can I make sure, which one it is. what should I ask the seller to look for?
Thanks
is 900/1900 not only in America ?
in that case you should ask the seller to look at his address
ok, my question is if it's possible to make the american version 900/1900 to work on 1800 mhz
most countries in EU have both 900 and 1800 support
here is a list not sure if its 100% uptodate though but i doubt people are limiting the support

Yes, only if the network supports 900 MHz
Zsilak, it will work on 900 but not on 1800.
Hey folks,
Is there a utility/hack that allows you to change the GSM band from 900/1800 to just search the 1900 band? Since upping to 1.72 my radio always locks onto the 900 band and stays there for ages before locking onto my operator (on the 1900 band). I have to have at least 80% signal level. I know that 900 generally is a stronger signal (the other operator is always at least 10-20% over my operator), so thats why [note: I cannot roam with the other operator].. I know the new iPaq seems to have a band select, and my Treo 600 does too....
HTC do you have a util?
Any help greatly appreciated.

under my phone settings i can choose network and set pref network and all kind of stuff like that
HTC do you have a util?

i really doubt that HTC hang around this site you i think that
any questions you want to aim at HTC have to be mailed to them
Try this: go to phone, tools, options, network, network selection and put it in Manual, select your network and OK.
Tell us if it works well thus.
If it dont work, you can install old radio version.
Thanks folks for the replies.. That's actually how I have it set now (manual on my operator), but for some reason when you turn the radio on it locks on to the 900 band and just sits there.. If I walk around until a strong enough signal is obtained from my operator it'll lock on; but as you can imagine this is really annoying.
Thanks again for your pointers. If I find anything out I'll let you know, as I've also shot an e-mail to Carrier Devices; and will shoot something directly at HTC.
I may also drop down to Radio 1.10; but I hate having to re-install all my software again..
You can make backup, install old radio version and make restore.
announces my MDA I (4.01.19/3.23.11/32S54) after cooking. My Provider is O2.
Has anyone a useful hint?
Thx.
.zaeng
What is the question?
Looks like the good old problem, that the 4.01.19 ROM sets the GSM band to 900/1900
You have to enter the bootloader and set your band manually back to 900/1800.
Since O2 uses only 1800 MHz this should be your problem....
Pay Attention Entering bootloader does the same like a hard reset. All data will be gone...

O2 in my country UK uses only 900 mhz, is this different elsewhere?

Hi,
this is the first time im working with with pdas so im totally new in this area. I bought one i-mate Jam and im using ok with one card provider, yesterday i change for other provider and i dont understand why my pda cant get network with this new provider.. i try to make a manual search and no information. the pda is brand new and i also contact the provider to see if is not barred and all is 100% ok... can someone knows if this can be fixed or have any ideia about this?
regards
For sure your unit is SIM locked. There are threads on how to unlock. Please do a search.
the pda is not locked becouse acept card without any problems... the only problem is dont get network of one provider.
What are OS ROM and Radio ROM versions in your unit? If it's an old one try to upgrade to the latest. There are a number of ROM's available in the FTP
Try your new SIM in other phones and see if it works ok. Also try borrowing from friends SIM of the same provider as your new SIM as well as SIMs from other providers.
The magician is a tri-band device build in two flavors:
- 850, 1800, 1900mHz
- 900, 1800, 1900mHz
Could it be the one provider which doesn't work is operating on a non-supported band?

hi,
i flash this pda few hours ago and i still have the same problem.. i was looking in other sites and i found something about this problem.
Exact this models have to versions:
PM10A (900-1800-1900 mhz) and PM10C (850-1800-1900mhz) and the one that i have is PM10C. I have to find one way to convert it to PM10A so then i will be able to fix this problem.
When you find the way to change a PM10C to a PM10A or vice-versa you're the man! It's hardware specific & not build in the rom :-(
M
i know someone that can make this change but dont share with no one... i cant do a lot becouse i have only PM10c in hands and i dont have any PM10A to compare the boards.
I just did a search with the keyword "850" and there are 2 pages of threads about this. All threads confirm what what OLTP mentioned - the radio frequencies are set via hardware components and no software or hack can change it. In fact, "Reo" mentioned that he modified the hardware of his unit to make it into a 900/1800/1900 MHz unit.
The 850 and 1900 MHz frequencies are used in the USA, while the 900 and 1800 MHz frequencies are used in Asia, Australia and Europe. I'm pretty sure that your new SIM supports only the 900 MHz frequency. Ask your current provider or check their website to find out what frequency they use. If your provider supports only the 900 MHz, then your last resort is to change provider again.
