Advice Req. Make a US T-mobile work in Australia?

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.??

Potentially Stupid Question - Telus GSM Radio on EU Hero

I've an unlocked European Hero, now in Canada. Is it at all possible to install the radio from the Telus Hero on this phone to alter the baseband 3G frequency, or is it hardware controlled? Anyone have success doing this?

You can not flash any radio roms as it is included in the current rom in your Hero. To flash replacement radio you need to take journey to Rootway.

I'm not sure what any of that means?
To answer the OP, I *doubt* that it would work, but doubting and knowing are two completely different things. It is conceivable that the physical radio hardware is the same from the Telus Hero to the EU one, and if it is flashing the Telus radio would probably work.
However, you run the serious risk of bricking your phone if the radio hardware is not identical.
Regards,
Dave

it won't work. idk whether it would brick the hero, but you can not alter the frequency related settings as they are hardware dependant. if you want 3g get the right device for your provider, no other way.

Hi Dave, Since he has unlocked EU hero, I doubt radio rom can be flashed at all but after flashing a new recovery he may be able to flash one fron the radio rom sticky as they are generic radios? Please correct me. Thanks.

People have flashed EU Hero radio rom onto Telus Hero (mainly because they want to root and install custom roms, but that requires downgrading the Hero first, and the downgrading process require the use of EU roms). Initial reports indicated some dialing problem on the Telus Hero with EU Hero radio rom. While flashing a newer radio rom fixed that, some people are still reporting some SMS problem.
One important thing to note though, using the EU Hero radio rom on Telus Hero does not get away Telus Hero's 850/1900 3G compatibility. This indicates that EU Hero 850/1900 3G incompatibility is not due to radio rom restriction.
As a matter of fact, the two are two different hardwares. The EU Hero (and all Asian) has product # HERO100 while the Telus one is HERO130.

Based on my experience with HTC devices, I'm pretty sure it's the same hardware. We need to focus on the baseband. Need someone with such skills like Geohot. Anybody?

Telstra Phone in USA, Should I upgrade to 1.66 WWE Rom?

Will that work? I am trying to make sure I stay on a "legal" ROM. Would I lose anything from a radio stack perspective? I need the US ATT bands to work? Any thoughts or recommendations?
Thanks!

I have a Telstra HD2 and I have changed the ROM, running Dutty's Holy Grail series, without any major problems so far. I get 3G on At&T just fine.
There should be no direct impact to the radio, if you go to the official 1.66 WWE Rom, but im no expert at that... you should ask the question in the RMO development forum

The bands your phone works on are hardware and are unchangeable. changing the rom will not impact on that.

I have a Telstra HD2 running Dutty's ROM - works great on AT&T 3G
It is based on the 1.66 ROM

I'm running a Telstra HD2 with the official 1.66 rom. I also changed to radio 2.07.51.05_02 I noticed much better battery life with this radio and with the stock telstra radio I kept having to refresh the data connection on ATT or it would loose it.

I have a Telstra and I am running Miri 6.5.xx ver 2.0 and it is must fast than the stock ROM or 1.66. Make sure you Hard SPL and then you can flash anyone's Leo Rom, it is great to get rid of all the extra software put on by Telstra. I have great 3g on ATT in CA.

Hope to get my phone by this Fri. So I can flash and enjoy the 3G.

AT&T US ROM/Radio Version Upgrades

Is anyone in US, on AT&T network with T8585 model, pleased with upgrades beyond:
ROM version 1.66.405.2
Radio version 2.06.51.07
That is what I'm running now, and am looking for any possibilities of increased performance on AT&T network in US. Has anyone installed upgrades beyond those versions and noticed significant improvements? Thanks.

Your Radio is fairly "old", might check the Radio Rom Threads, some of the newer radios perform better in some areas, for different people ....

Thanks for the quick help. Is the Radio Version dependent on whether it's the T-Mo version or the stock T8585?

As a rule of thumb, just make sure you stay in these forums rather than the TMobile HD2 forums (which are separate, and say TMobile in the name ) and you should be fine.
As to what's "best", it's different for every phone in every region. I'm currently running 2.12.x, but there are plenty running 2.07.50.x, 2.10.x, etc. Just try em out for a few days and see what works for you.

except that non tmous hd2 can flash all the tmous roms and radios, so no problem

Ah good to know.

With SPL v. 1.42.0000 installed, will that be sufficient to try various Radio Versions, or is it necessary to have a newer SPL version than that? Also, any direct link you are aware of for step by step radio version upgrade? If so, thanks in advance for saving me some time searching on my HD2 on Edge.

none of the spl's will allow you to flash radios. You need hspl.
(unless you meant to type you had hspl 1.42.hspl? 1.42.0000 is stock)
if you havent hspl yet, get hspl3 from mysig, (or the hspl thread) run it, choose 2.08.hspl, then you should be good for flashing roms, radios or whatever you like.

Tried a radio version upgrade to: 2.12.50.2_2. Wasn't working as it was cutting out voice on my calls every other second. Trying the version listed below and that seems to be working fine so far. Anyone else on AT&T US bands with T8585 having particular success with a specific version?

Hi all, Sorry to possibly hijack the thread, but I wanted to ask a quick question about flashing an HTC HD2 radio. I'll be getting my HD2 sometime this week (it's a TMobile US version) and I plan on using it on AT&T. I understand this shouldn't really be a problem out of the gate for normal call usage and data edge usage as the radio frequencies are the same.
However, I was wondering if it's possible to flash the T9193 radio rom onto the version I'll be getting (T8585 if I've been reading and learning everything correctly) so I can use the AT&T 3G 850mhz band?

No.

You won't get AT&T 3g connection with T8585 version (no radio will make T8585 get AT&T 3g connection since T8585 doesn't have 850mhz band). You get AT&t 3g if you have T9193.

[Q] Unbranded Rom for Tmobile HTC leo

hey i recently purchased a tmobile branded htc leo the 1024leo for tmobile usa. I wanted to flash an official unbranded rom. Anyone know any that will work i downloaded RUU_Leo_HTC_WWE_1.48.405.2_Radio_Signed_15.28.50.07U_2.05.51.05_2_Ship.exe
thinking it would work but after reading that not all roms work i realized this might not be compatible. So if anyone knows any unbranded roms that work tell me plzz. also any way can sim unlock the phone by flashing or using some software cuz im on att and i really wanna use this phone

there is no "official unbranded rom" for the tmo us HD2. You can download many different customized rom that is available such as the HD2.0 UnOff Series if you want unbranded. for unlocking please use search there is already a thread about that.

i don't know about that rom, but i always follow this rule when i download any roms:
PLEASE READ ALL THE INFORMATION IN THIS GUIDE BEFORE INSTALLING HARDSPL OR FLASHING A ROM/RADIO. IF YOU FLASH AN INCOMPATABLE ROM OR RADIO ON THE 1024LEO THEN THERE IS A POSSIBILITY OF BRICKING YOUR DEVICE SO PLEASE BE VERY CAREFUL!!
Not all ROMs are compatible with 1024LEO, including old official ROMS.
Official 1.42 and 1.66 WON'T WORK on LEO1024, because there is no 1024 NAND memory support.
All custom ROMs which ARE NOT BASED ON 2.08+ T-Mobile ROMs WON'T WORK ON 1024LEO.

and this is the rule for radio
IMPORTANT: Do not flash ANY Radio before 2.07.x or the 2.09.51.03 Radio or you could damage your phone!!

it was just an suggestion about the rom, and shawnamin should have read the "[TUT] Flashing your First GSM USA 1024LEO ONLY!! (For Noobs)" and that would have given the answers for flashing roms.

Heh, wise move.
Your tmous phone cannot take ANY official roms at all, except for the tmous official roms, or tmous compatible cooked roms. All other official roms contain a radio that will kill your phone permanently.

Moved as not ROM Development.
