does anybody know if i will lose my
850mhz band on my usa sp3i if i
install the wm5 flash at
opencodesolutions.com/~ronswens
???
I can't find an original rom, so going back would be tricky and i can't afford to lose the 850mhz i have now.
thanks!
as far as i know that's the radio hardware and not the software (i.e. the rom) that controls that.
I doubt you will have any problems, although i have tried and it's not very easy to upgrade the sp3i.

Hi, I have aquired a T-mobile from the U.S.
Before attempting to re-flash it to get it to work in Australia I just want some advice that I am about to do the right thing...
Here are its specs:-
Branded T-Mobile
ROM v 3.08.10ENG
Radio v 6.02
Model PW10B1
After some reading of these forums I have concluded it must be a 900/1900 GSM device, and it appears to be SIM locked.
(Here in Aus. we have a 900/1800 GSM system).
I intend to use a cooked rom from jeffs site to upgrade the rom.
Does the rom I use have to be one of the T-Mobile US roms ?
I realise that i wont have 1800 coverage. But will 900 still work?
Anyway, because of the sim lock I intend to proceed with a rom update.
I intend to:
Backup rom using SD card method
Download a V4.xxx T-mobile US cooked rom
Update rom using USB method
Any comments/advice appreciated (any local experience here?)
Regards from DownUnder.
well first off... i suggest you upgrade to Special rom 1.2 first.
that one will unlock your pda, so you can use it anywhere.
and about band... i'm sure i saw 1800 in the bootloader!
but not sure if you select it as default if it will carry over to the os
maybe worth a try.
in any case, if you back up your os onto SD, you have nothing to fear.
i say best thing to do, is copy that O2 os & radio (if you're sure u'll never leave australia, i dont think radios can be manipulated that often)
but dont take my word for it. wait for a confirmed user. if your not advanturous
Good Luck!
Yep, I backed up and upgraded to SE v1.2 rom using the SD card/OSImagetool method.
SIM unlocked ok
Phone works if 900mhz band is selected.
Its now thinks it's a model PW10A1.
Radio is still the 6.02 version. (B ver. )
Not sure what the consequences of this are.
Im not sure if i would benefit from a radio upgrade or not.
If I understand this correctly, I can ONLY upgrade the radio to the T-Mobile US versions, because the radio hardware is B version.
I think I will leave it like this for a while, see how it go's.
Anybody have any experience with using a B (US)version radio in a A Ver.(euro/asian) area.??

Thanks for the advice ntabikha and THANK YOU to the XDA Developers team.
Hi. I started with an AT&T Siemens SX-56 with XDA Developers final 2002 software.
After burning my own 2003 ROM with Lumpi's kitchen, I installed from USB cradle. No probs.
Then I tweaked a new ROM, but it wouldn't work with USB. I had to upgrade it by SD method. Worked fine.
Don't ask me why (maybe I like having all newest versions), but I upgraded the radio using T-Mobile's 2003 updater.
I've since burned a new ROM I made in the kitchen.
My question is: I now have Wallaby Bootloader 5.22, T-Mobile kitchen ROM 4.10.16ENG 02/04/04, and Radio Stack 6.25.02. GSM Band doesn't work anymore. Is there one that will work?
I can sucessfully use Wallaby menu and change back and forth from 1900 to 900/1800, no problem, but,
1) is that the only way I can do it when I travel back and forth to Europe?
2) can I downgrade the Radio stack?
3) what versions (in your opinions) of ROM and Radio are the best/most stable/whatever...? (Internet isn't so important to me, but good cellphone signal is)
Thanks a million!
I love this site! Awesome!!!!!!

p.s. If anyone has questions about SX56 and how to get stuff to work and what happens when you try things, just ask! I've got a spare one I do all my testing on...[/b]
I used 6.24.01 and 6.25.02 RSUs with 900 MHz ... in general there is almost no difference ... both are performing in an acceptable manner. However, I have a personal feeling that 6.24.01 was a bit more stable (I maybe wrong tho).
In all cases, as long as you have a good RSU don't touch it ... it's a risky process unless there is a real need. I didn't try the GSM band switcher my self, but I heard it requires soft reset after.
Australia uses 900/1800 bands. What Roms will work perfectly with these? I have the T-Mobile 4.01.16 and the reception is bad...The network itself is good because i get perfect signal on my Nokia 6600.
Can you please let me know which one and where to get it?
The ROM has nothing to do with this issue ... it's the RSU version ... and for 900/1800 I think 3.25.01 is perfect but plz check with your operator first ... again, RSU flashing is so risky!!
Hi all,
Could someone please advise me if i have a XDA1 or a paperweight, I use a XDA2, but as i had a old 32MB XDA1 with what looked like the version befor PPC2002 i thort i would be clever and put a 2003 rom on it.
its a uk 900/1800 PW10A1 device, anyway with delay i dowloaded the latest 2003 rom i could find ( T-Mobile 2003 4.21 beta) anyway i put the relevent file on a SD ard and upgraded that way.
As this had lots of T-Mobile bits i did not wont i found a older non network branded 2003 rom. but my problem is the devve is now listed as a PW10B1, and of ocrse i cant use 1800 anymore, ( iam in the uk and was going to use it on Orange (1800),
I have read throught the forum and tried many ways to fix this with various roms and then in the phone section changing bands , also bootloader all with no affect, the best i can get is a fresh earlie clean 2003 rom but only working 900mhz.
Dose anyone have any ideas last resorts how i can make it work on 1800 like it did befor i jumped in head first and not reading that the t-mobile 2003 rom will make it a 900/1900 device
any idea even if it compleetly kills it it was wort a try
Thanks
John
do a search in the forums there have been tons of posts about how you downgrade the radio stack
personaly i dont know because
the main reason we use xdatools to upgrade our devices to
so we can use the nbf file only making sure the radio stack is not
messed with
Thanks Rudegar
I have tried downgrading the radio, some times it works and sometimes it dose not I either end up with no radio or as i have at the moment a radio stuck on 900mhz, i have found 6 or 7 different radios but none will let me use 1800,
Is there a way i can kill the radio the hopefully get it to restore to the original
Thanks
John
Hello,
I was going to purchase a Telstra 9193 Australian version which has HESPA 850. My question is regarding flashing a custom rom. If I leave the radio stock and flash a rom will it work since it has a different frequency?
Anyone bought one for use with Telus or Bell or guess AT&T and flashed a custom rom? I have been reading about a setting for frequency?
Also do you know where I can get the stock Telstra rom so if i need to go back?
Thanks
I imagine it should work as long as the radio rom is intact, but I'm not positive and would also like to hear from somebody who has tried using the Australian Phone.
I would gladly buy another HD2 to get US 3G...not on T Mobile.
I have the Telstra HD2 it works with 3g in NA with flashed roms and also with upgraded radio ( currently I have the 2.8)

The Australian version is compatible with carriers who run 3G network on 850Mhz (Rogers, AT&T, Telus, Bell ...). I`m using one right now with Rogers. This 850Mhz frequency is hardware related and can`t be altered by flashing the radio. On some custom ROMs which required to use certain radios to enable the 576 RAM.
Should be fine

I've flashed two ROMs (including a 23541-build) on to two different 9193s (the Telstra model - I don't believe there is any 9393 model), and they have been working fine. Better than the stock ROM. Also flashed the Radio on those phones to 2.08.50.08, and no problem there either. My bet is that you'd be fine.
Hey I'm using it on telstra in Aus, and I also have found no issues. Works well, no stress.
Well guess I will be flashing Thank you for the replys. I was getting confused with some saying there was a frequency setting in the rom and i did not want to brick my device.
I am very interested in using the Artemis rom on this Telstra 850mhz device. If anyone is doing that please let me know.
THANKS!

You will lose the 850Mhz frequency in the frequency setting when you flash the custom ROM. The reason for that, I think, is because the custom ROM is built from the EU/Asia base system. But no worry, there's a .cab from here http://forum.xda-developers.com/showthread.php?t=624108&page=6 (post 58) where you can restore the Australian version frequency setting

Unless you are flashing a crap rom you wont loose this. I haven't lost this in any rom I flashed. Just because the phone doesnt offer the hardware doesnt mean wimo doesnt show the bands look at the tp1 tp2 from europe both showed 850 as an option just didnt work for hsdpa
