I bought a sx56 (AT&T)from ebay seller and i am now in Saudi Arabia i made unlocking using the especial edition rom from XDA-developer but no signal after that and the device can not find the network even after making band width adjustement to 900 (here in saudi arabia)
Rom version 3.17.03 Eng
My RSU is 4.21
any one can help please!!
what's your device type ? ... A or B ?
You selected 900 MHz from the phone settings or the bootloader GSM menu ?
I selected the 900 from the a program called gsm band it is already been with xda-developer special edition ROM.
How do i enter the the bootloader? and change it to 900
And by the way it is A type. does this type do not work in the middle east or what?
Ramzy,
I had an sx56.
I got it from USA and it works fine with me here in Dammam.
All what I did is change the bandwidth to (I am not sure if I change it to 900 or 1900) any way try both.
You need to go to the phone dialing (The one with numbers and buttons)
Then go to Tools/Options and then Band I think and change it there.
Also, while you are there try to go to Network and find the network manually not automatic.
InshaAllah it will work.
thanks
The device type is the whole point ... check the rear sticker ... if your device is PW10A that means it supports 900/1800 MHz ... and if it's PW10B this means it works for 900/1900 MHz.
The RSU should be the proper one as well ... 900/1900 RSUs will give you 900 only if your network is 900/1800.
Check the device type first, if it's A and your networks is 900/1800 then you should NEVER switch to 1900 MHz
The best and safest way is to use the GSM bands from the bootloader menu. Press soft reset while pressing power ... when it says "GSM OK" press the calendar button and select the right band.

Gents,
I have been following this forum for about 9 months now; it is a great place to visit if one has an XDA – which I do.
I have one question, I upgraded my Qtek1010 to rom ver: 4.00.21 ENG (from yorch.net), it gives an option to select band 900 (Europe) or 1900 (North America). Does 900 really mean 900 or does represent 900/1800 (Europe), i.e. can my mobile still hand over call to cells on 1800MHz in Saudi or is it limited to the 900MHz band as a result of this upgrade?
Thanks for your help
it should be 900/1800 i think
i seem to recall that EU were at first 900
and asia were 1800
and us were 1900
then dual bandphones came and
you could get
900/1800
and
900/1900
not sure about 1800/1900
so it should work on both 900 and 1800 because the phone is dual
I dont think the upgrade changes the hardware capability, the phone will be 900/1800 or 900/1900, the latter can only be used in UK/europe on the 900 band, the 1800 is not achievable as far as I know.
yes 900,hz means 900 only which means if you have been into the band tab in the phone options your device will now be stuck at 900mhz only meaing you have lost the 1800band.....
and 1900 wont work it wil lcause your phone to freeze/no signal.
what you should do is go into your bootloader and achange it to 900/1800 and do not touch the band tab again becuase if you do you will have to select either 900 or 1900
this is because you are using an american rom.....
use v4.00.05 or v4.00.11 they are english roms with 1800/900
Hi ...
The siginifact point is the device h/w type ... is it PW10A1 or PW10B ?? ... refer to the sticker on the rear side of the XDA.
In case it's A then it supports only 900/1800 and the 900 option will mean 900/1800 and the GSM menu should be adjusted to the right band ... if it's B then it's 900/1900 and you can only use the 900 MHz band of your network coz the H/W doesn't support 1800 MHz
Either the GSM menu or the Band tab has no effect if the H/W doesn't support 1800 MHz
Folks,
Thanks for your help, I guess until I downgrade to 4.00.11 ENG I will use the bootloader to set it to 900/1800 and stay away from the band tab.
Thanks again
you can use any version you want mate but if using an american rom like what i am at the mo (v4.01.00) just dont click on the band tab under the phone options as once you do theres no way to close that screen without select either 900 or 1900
if you do select either band just go into the bootloader and put it on 900/1800 again and dont touch the band tab that way you will still have your 1800 mhz band too
gaz
soft reset will solve the problem :lol:
lol yeah that also but why not try avoiding the band tab once and for all lol that way you wont have to reset the bootloader bit or reset it if you go into the tab lol
gazzaman2k,
You recommanded using 4.00.05 or 4.00.11, I found 4.00.05 in yorch.net, do you know were I can get 4.00.11? I'm assuming it is a better rom!
Thanks for your help
searche the forum for it mate youll find it v4.00.11 uncooked
The only place for 4.00.11 was Jiff kitchen but it's down now
The ROM part of TMO 4.01.00 is not bad at all ... I have it since 2 months now and it's so stable ... didn't try it with SD cards tho
you may consider this upgrade ... again, the ROM part only
I just bought me a QTEK 1010 with ROM v3.08.10ENG and Radio version 6.02.
But my Operator only operates at 1800 Mhz, and i think this phone can only handle 900/1900 (its has model no. PW10B1). Is there any way how i can change this ? or is that impossible?
thx
It wont work, or if it did it would be extremely flaky if it managed to connect bearing in mind the 100mhz difference in frequency.
Hmmz, while i was googling for WALLABY Bootloader, i came on the main site of xda-developers where the bootloader was describer. Then i went into the UTILITIES screen of my bootloader, and changed my settings to GSM 900/1800. And i rebooted my phone.
It looks like it's now running on my 1800 Mhz provider, cause i can make phone calls!
Does this mean that it IS a triband phone?
Not really, where people have been able to get 1900 on 900/1800 phones it has been very flaky at best, let us know how you get on using 1800. By the way, which operator are you using.
Change 900/1900 to 900/1800Mhz ....
I bought a SX56 few days ago in eBay(US) .... I decided to buy because the guy was sure that his phone was TriBand... but when I started to use here in Brazil, I realized that's impossible to find a carrier ...because the GSM here is 900/1800Mhz.... instead 900/1900 from US GSM Mobile.
How can I change the band ???
I presume the SX56 is 900/1900 because I read a AT&T logo ...
But I need to change to 900/1800Mhz...
Could you help me ???
Thanks,

Hi guys,
thought of saying a couple of important notes:
1. when checking the type of your device, refer ONLY to the sticker on the rear side. do NOT depend on what's written in the device info!
2. the xda 1 is a "dual" band device either 900/1800 (A type) or 900/1900 (B type). both ROM and GSM menu will have the 3 options but this doesn't mean it will work. if you want a tri band device get the xda II
Hello
:shock: XDA 1st working good in Russia . The phone and GPRS .

You can try what this other person did: change the band in the bootloader.
Hold the power button while performing a soft reset (large hole, bottom left). After you see the bootloader screen, press the calendar button (top right above display). The options 900/1800, 900 and 1900 are all in the menu. Move with rocker keys (below screen), and press the middle of the keys to select. The soft reset again (without holding power).
1) You may need to remove the SIM and put it back in before the phone 'understands' the change.
2) Your radio part is now operated 100 MHz or ~5% out of tune. And it wasn't a very good GSM radio to begin with. Pray the 1800 provider you're with is high in the band.

After you do all this, does the original Radio ROM 4.xx.xx or whatever compatible as before? People used T-mobile 6.xx.xx in US for 900/1900 Radio but 4.xx.xx in Europe for 900/1800 Radio.
I knew in the wallaby bootloader they have that utilities but you may need to change the radio as well, is it? I guess....
After testing the mobile on 900/1800 for a while, i would not advise it to anyone of doing it, cause my connection is really sucky sometimes.
If there is anyone in europe who wants to have an XDA 900/1900 for testing purposes and exchange it with an 900/1800. Let me know
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.
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.
Omi
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 ?
Omi
I have O2 XDA, with already installed Special Edition ROM 1.2. When SIM is inserted, this device is supposed to find network. BUT: no netwroks are found at all in this range! Switching between 900/1800/1900 does nothing. But still, after inserting the SIMcard, this device asks for the PIN-number, and is able to read the contents of the SIM - so SIM is not the problem... So what can I do to make it find network?
ps. Location - Russia, Service provider - BeeLine (federal number).
pps. I got this device used. First, this device was used in the 1900 mhz region - and was working perfect (1-st owner). Then it has been re-sold to the 2-nd owner, who used it as PocketPC only (as he was in 850 mhz region).
Please check model type of the rear sticker.
PW10A is for 900/1800 MHz networks and PW10B are for 900/1900 MHz networks. I´m guessing that´s your problem. If your provider just uses 1800 MHz you can´t use a PW10B-device....
