how to go back to 900/1800 (which rom?) - MDA, XDA, 1010 Software Upgrading

After upgrading to t-mobile rom gsm module was working until I hit the "band" tab from phone menu. of course what happened I realized after reading posts from forum.
Now, I need help how to go back to 900/1800 frequency (Poland) - which rom to use, where to download it or how to change to these frequencies.
help pls.

for 900/1800 use v. 4.00.01, 4.00.05 , 4.00.11 for upgrade to WM2003
(v.4.01 & 4.05 you can up/downgrade by program setup)

you can switch it on the bootloader !!!

more help with xda

hello again folks ...
want to say thanks again for all the help so far .. upgrade went well ..
i went from :
rom version: 3.14.17 ENG
rom date: 10/11/02
radio version : 4.17
to the upgrade :
rom version: 3.17.03 ENG
rom date: 5/15/03
radio version : 4.17
courtesy of www.yorch.net 8)
it was fairly painless ... however the phone still can not pick up a signal ..
also note with upgrade i have been able to switch GSM band from 900/1800 to 900 or 1900 successfully.. but, still can not find t-mobile US as a default setting ...
perhaps i should have cooked and installed one of the following upgrades ? :?
4.00.10 ENG T-Mobile US
or
4.00.16 ENG T-Mobile US
i was hesitant because it indicates once the above mentioned ROM is installed you can not switch to any other ROM using programme A .
my device model no. PW10A1
does this apply to me?
or perhaps i need to udate the radio stack ?? any direction would be great .. thanks again folks !
jason
use 4.00.16 ENG T-Mobile US then once loaded onto xda go into the bootloader (hold power button down while soft restting) then press the calendar (right hand) button and set it to 900/1900mhz
then wait for it to do what it has to do then softreset again.....
then load the phone up with sim in go into phone then options and click on the band tab and select 1900mhz
softrest after if it doesnt pick up signal after then the aversions are not kinda tri band but if it does post up then we will know the answer for deffinate thing is though the radio version is built for 900/1800 not 900/1900 so i dont think itll work but you can try
my device model no. PW10A1
does this apply to me?

If the H/W of the device is A type then it's 900/1800. So, unless you have a 900 MHz signal it will not work. Switching the band from phone settings will have no effect unless with proper H/W and RSU version.
ok fellas ...
i went from :
rom version: 3.17.03 ENG
rom date: 5/15/03
radio version : 4.17
to the upgrade :
rom version: 4.00.16 ENG T-Mobile US
rom date: 7/10/03
radio version : 4.17.00
courtesy of www.yorch.net
however the phone still can not pick up a signal ..
with upgrade i have not been able to switch GSM band from 900/1800 to 900 or 1900 successfully through the wallaby bootloader (after changes are made i can not get out of bootloader without doing a hard reset) :? also note the xda developers band switch tool is also present but reads error :?
also note :!:
before the upgrade
my device model no. PW10A1
after upgrade
my device model no. PW10B1
not sure if im getting any closer to the solution but im still happy at this point i havent burned up the unit ...
perhaps it is still an issue of the radio version 4.17.00 (which is the only thing i havent fooled with yet)
any thoughts on trying the radio upgrades from www.yorch.net (under upgrades) ??
if this doesnt kill me it will surely make me stronger ... i will throw a party with beer for everyone if we can get this turkey running !!
thanks again folks !
If you can read a B type on your device that means your H/W supports 900/1900 MHz. To be more sure, check the avaialble options at the GSM menu from the boot loader (Power + soft reset then Calendar button).
If it does have the 1900 MHz option, I would recommend to go for a full upgrade using the latest TMO ROM 4.01.00. It contains RSU 6.24.01 and it works perfectly well for me tho I have 900/1800 network.
Here is the link: ftp://tmobile:[email protected]:21
Be careful and good luck ...
It may be important to note at this point that the OS ROM version really doesn't have much to do with whether or not the phone gets a signal. XDA I is either 900/1800 (PW10A) or 900/1900 (PW10B). (Please note that this model number should be taken from the sticker on the back, not from what the OS says it is.)
If you have a 900/1800 phone, it will not do 900/1900, and vice-versa. Exceptions are said to exist, probably in places where a 1900 provider is really low in the band (or an 1800 provider really high), but this is not recommended and unlikely to work very well.
Band switching is done manually with an extra tab in the Phone Options page between 900 and 1900 in US ROMs, or automatically between 900/1800 in all others. There is also a band-switch in the bootloader, which always offers all possibilities (900, 1900, and 900/1800). After selecting the correct band for your phone, you may need to hard-reset with the SIM removed a few times before the phone 'understands' it is to use another band.
If you want a tri-band phone, get an XDA II. The XDA II by the way comes with vastly improved radio performance. Unlike the original XDA, I can use it in areas with not-so-great coverage.
>any thoughts on trying the radio upgrades from www.yorch.net (under >upgrades) ??
Yeap you're needed of a Radio Stack upgrade, as you have seen 4.17 won't work in the US. So I suggest you upgrade to the AT&T or the T-Mobile stack.

ROM: 4.01.00 ENG

i would love to try this upgrade ...
can anyone tell me where i could download it? :?
thanks

Thx Peter Poelman so much for this great info, but my original Qtek 1010 never showed the 1900 Mhz option in the boot loader menu and it was PW10A.
Now as I replaced the main board with a one taken from a used TMO device it shows the 1900 option both in the GSM menu and in the phone settings in ROM (I 'm using 4.01.00 now) and the device type is PW10B
Does that mean that the GSM menu shows only what the device H/W can actually support, or it's part of the RSU file contents which may give a fake option of the 1900 MHz ?
Thanks again for correcting our info

also note ... unit is an o2 from singapore .. i am in the US trying to access the Tmobile network ... originally it was PW10A .. after the second rom upgrade .. it switched to PW10B ... and also appears to have all 3 bands available from the bootloader .. after 3rd upgrade/downgrade to
rom 4.01.00 eng
radio 6.24.01
still appears to be PW10B1
it is searching for a signal
thoughts anyone? :?
It might be your SIM card so try it in another phone and if it works.

SX 56 change frequencies on xda rom

Can't switch frequencies to 1900 to use phone in central US. I push 1900 and it says error and goes back to 900 which does me no good.
What can I do?
What RSU version ?
Do you do this in phone settings or GSM band switcher in boot loader ?
Change Frequencies
Not sure what you mean by RSU, but I have the XDA special edition rom 3.17.03 eng and I am doing it in the phone, I don't how to start bootloader. Thanks.
RSU stands for the Radio Stack of the device (the phone thing) ... you can read it in device info ... and if it doesn't support 1900 MHz then it's useless to try it from the phone settings.
Also, your device must be PW10B to work in 1900 .. check the rear sticker
you can start the boot loader by pressing and holding power while soft reset ... then press calendar button to go in the GSM menu.
Got into the bootloader and set to 1900. I have a PW10B1, but device info says I have a PW10A1. Why is this. The phone will now pick up a signal on 1900 but the reception is poor. Looses signal where it used to have a signal.
Radio Version is A.33.02
ROM Version is 3.17.03
Do I need to get a different ROM to get it to match a PW10B1?
Also, can I put my old ROM back on? I have it on disc? Tried to reload from Siemens site and it said I could not load on to this device.
Thanks, you have been very helpful!
It seems you used the 3.17 ROM to unlock ... what was the original ROM ?
well, I 'm the last one to advice on RSU flashing ... it's risky unless really really necessary ... check with your friends in the same area on the best RSU ... ROM doesn't make any difference.
If ok, I would recommend ROM 4.01.00 with RSU 6.25.02 ... you can cook the ROM in the kitchen but leave the RSU action as a last option
Original ROM A30.09 ENG
Radio A33.02
Since last post I figured out how to use XDA tools to get Siemens upgrade ROM back on and now every thing seems to be fine and unlocked which is what I originally wanted to use with Cingular sim. I will have to roam on ATT to use this but is OK since I have free roaming.
If I have any more problems, I will post again.
Thanks!

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

you need change radio stack back to PW10A, but risky
so i cannot set it back to PW10A ?????

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
Hello all,
I have a XDA i have a problem with the radio stack, Frend of mine did and upgrade of Rom and Radio, and he did a PW10B1 radio upgrade is there any posibbileties to downgradit to PW10A1.
Thanks in advanced

Can not pick up the network after finally unlocking..HELP;-)

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!

2003se, final and GSM900|1800

Sorri for bad english.. i`m Russan.
I have T-Mobile MDA 1 32mb. PPC2002
Have ROM (on kitchen) 4.01.16
Radio 310.
I see "Settings" - "Phone" - "Band" GSM 900 (Europe) and GSM 1900 (North America).
My GSM operator work 900|1800. How to switch it?
The second question. It is impossible to establish 2003SE.
.exe not working. Error USB connect. How?
xda2's which the imate is support 900/1800/1900
xda1 comes in 2 versions one which is 900/1800 for eu
and one which is 900/1900 for us
there is no way i know of to change an xda1
I've to correct Rudgear a bit....
ROM 4.01.16 sets in most cases the band to 900/1900. If you got a PW10A modell (check rear side of your device) you have to set it back to 900/1800 via Bootloader
Instructiony could be found here:
http://wiki.xda-developers.com/index.php?pagename=ChangingBandsWithBootloader
Pay Attention: Entering Bootloader is just like doing a hard reset, so don't forget to backup your data.....
Concernig your problem about Upgrade to WM2003SE. A mentiond 1000 times here in the forum, this causes from the t-mobile ROM installed on your device. You have to downgrade the ROM first to a "normal" ROM (like the special edition ROM) via SD-Card, and then you can upgrade via exe file to WM2003SE
