Hi
I have recently purchased an HTC Wildfire A3335. For those of you don't know, this is a special version of the Wildfire which has a UMTS 850/2100 Radio. Anyway this phone seems only to be available heavily branded through an Australian operator, Telstra.
Due to the hideousness of the branding, I naturally wanted to get rid of it. This was pretty easy-- Cool-- I now have an unbranded wildfire A3335.
Now, when it was flashing (using an HTC RUU exe) I noticed that it was "Reflashing the radio". I freaked out. I know this phone has a special radio in it and of course the unbranded RUU is for the 900/2100 UMTS version (A3333).
So as expected the phone has lost its very special 850MHz UMTS and now only works at 2100MHz (I doubt the phone has suddenly gained the ability to use 900MHz UMTS as it has the wrong chips in it)
The Radio image for this phone is available inside the Telstra RUU on shipped-roms.
My question. Is it possible to extract the radio image out of that and flash it in with the rest of the unbranded system? And hopefully get my 850MHz UMTS back. Currently it appears that the answer to this is no due to the lack of signing?
Current HBOOT: 0.80-0007
Current ROM HTC Standard (Eclair 2.1) 1.37
You can't lose or gain any frequencies by flashing the radio, it's in the hardware...
OK firstly, I did lose 850MHz when flashing the standard image on, so you definitely can lose (but never gain)
The Radio PHY in the phone will be split into two parts, the 2100MHz part and the 850MHz part (or a 900MHz part).
So on the normal wildfire radio image, there's a driver which is likely compiled to drive a 2100/900 radio, and when we run that image on the 2100/850 phone, 2100 remains working because this part of the chip is identical. The 850MHz part dies completely because this driver is not expecting it.
I know how lazy microcode developers are - it's very rare for anyone to go to the effort to make microcode images to support two subtley different chips, instead they will compile two versions of the microcode with subtle changes for each one. Only one bit in a register need be set wrong and the whole lot comes crashing down!
Now there could be a scenario where the radio is a 100% hardware solution, and there is no microcode for the UMTS radio, in which case there's a better chance that having the wrong radio image is not an issue, as the chips themselves are more autonomous. But then - What does the radio image do? In my experience of working with 802.11 Radio PHYs: Not likely. These chips are almost always highly software driven and must be running the correct code to fully function.
Okay so it looks like I just became the "expert" on this one and can now answer my own question.
It is possible to restore the original Telstra radio image, without rebranding the phone using the Telstra RUU.
This is what I did:
1) Download Telstra RUU from shipped-roms
2) Extract radio.img using this process: http://lukasz.szmit.eu/2010/04/extracting-rom-files-from-htc-android.html
3) Repacked radio.img into an update.zip
4) Signed update.zip using http://android.modaco.com/content/software/313829/pc-tool-zip-signer-v1-1/#entry1348449
5) Manually added com/google/android directory into META-INF directory in ZIP file (Copied from someone else's radio image.
6) Flashed image using clockworkmod "update sdcard" menu (unrevoked had already installed clockworkmod)
Done! I've got my 850MHz back again!
I've included the update.zip with the Telstra wildfire radio image here: http://xpander.inaxeon.com/data/files/update.zip
It's interesting looking around the various forums, I think a lot of people have been willy nilly flashing the wrong radios onto their special 850MHz devices then not fully understanding why their phones are without 3G coverage a lot of the time. Oops!
Interesting, last time I checked the radios were identical. I must have missed something. I'll try cross flashing the Telstra A3335 radio on the 900/2100mhz A3333 and see what happens, 3G up here in Canada runs on 850/1900, getting 3G on one of the 2 bands would be nice.
Edit: It's the same as the other radio of the same version 13.45.55.24/3.35.15.31 , did a checksum against the HK_CHT one (cid HTC__622, a A3333)
Maybe the "H" in the version have something to do with the frequencies? ie: Radio_13.55.55.24H_3.35.20.10 from the Froyo WWE rom.
Did you not read my second message!
Unless you have an A3335 flashing the Telstra radio is going to make your phone even worse!
The full solution for 850MHz UMTS requires:
A) The right hardware: (Wildfire A3335)
B) With the right software: The Telstra "Radio_13.45.55.24_3.35.15.31" is currently the only radio image in existance which can correctly drive the A3335, and in no circumstances should be flashed on anything other than the A3335!
Likewise - If you have an A3333
Do not flash the Telstra radio image on it, as it is the wrong code. You'll end up losing your 900MHz UMTS in the process (OK so that doesn't matter too much in Canada)
To say it even simpler:
Every radio image except Telstra is OK for use on the A3333
The A3335 must be running the Telstra radio image
Telstra Radio_13.45.55.24_3.35.15.31 is a special piece of software for a special piece of hardware!
EDIT: Kwen has checksumed the A3333 and A3335 images of Radio_13.45.55.24_3.35.15.31 and found them to be identical. This confirms that this paticular version supports both 850/2100 and 900/2100 phones, whilist newer versions do not. See more recent posts.
i have a telstra wildfire which i have wildpuzzle v.08 running on, with putting a new rom on i would presume i have a different radio, am i correct. yet i can get 3g and wcdma/hsdpa no problems. or am i confusing myself
Thanks for this. I'm going to keep the update.zip safe just incase.
I've just imported an A3335 to use on the Telecom XT network here in NZ and I just flashed it with DK's rom (shame that I'm still stuck with the Telstra splash screen).
Although 850MHz is the primary band Telecom uses for their network they also have 2100MHz fallback in my location, so I'm not 100% sure what band the phone is running on.
Is there a service menu or an app on the marketplace I can use to check the band for peace of mind?
Thanks again.

It made no difference, couldn't tell if I lost the 900Mhz, couldn't get the 850Mhz for sure.
I tried playing in the Field test menu to switch between GSM Only to WCDMA Prefered/Only and the Band selection menu and completly lost access to GSM, it was stuck on WCDMA Only, had to do a nand restore (nothing to do with the radio version)
I'm not sure if the Radio_13.45.55.24_3.35.15.31 is exclusive to the A3335, most of the roms uses it:
Vodafone SPA
H3G ITA
HTC WWE
HTC Asia India
HTC Asia WWE
HTC Asia HK CHT (that's my phone and it'ss a A3333)

HTC Asia TW
HTC FRA Bouygues

How did you find out which band your Wildfire was using? (or did you just not have any signal?)

Pretty easy. My operator has no GSM (at all) or 2100MHz sites where this phone is most commonly used. When the alternate radio was flashed on, the phone flat out lost all connectivity to the network. It only returned when the phone was driven to a place known to have 2100MHz coverage. That was a pretty damning and poignant confirmation.
About the versions of the Radio, When I was first considering flashing the RUU I had already been concerned about the radio image and checked the version. I saw that it was used in other A3333 targetted images so assumed that the radio images were not phone specific. Turns out I was wrong.
What would be interesting is to checksum compare Radio_13.45.55.24_3.35.15.31 from Telstra vs. other images. If they are identical, then we know that this particular version supports both style of radios, in which case it is safe for both versions. The reason I've always been qualifying that version "Telstra" is in the fear that they are different despite the identical version number.
Short of actually being a hard core hacker or HTC engineer, It's a bit hard to tell really. All one can really do is share their experiences.
I can confirm thier identical checksum (I checked against another one - not all the versions lol)

Hey man, I have a wildfire which runs on these frequencies GSM/GPRS/EDGE: 850/900/1800/1900 MHz and HSPA/WCDMA 850/1900 MHz.
I was going to flash a stock RUU till I read your post, so I wanted to thank you for saving my precious 3g!

What the heck model is that!
I understand HTC may have a provision for 850/1900 (Model A3334) But as far as I knew that never went into production due to lack of interest from operators. Or is this a fruity variant of one of the new Wildfire S models?
EDIT: As bought to my attention by juanchotolas - it appears that the 850/1900 A3334? (Awaiting confirmation of the exact model number) may exist after all. It leads a low key existance in Latin America sold under an obfuscated difficult-to-google-for name. It's called "Desire A" but it's really a Wildfire.

I've spent many an hour searching for such an application and one does not seem to exist. Post one here if you find one.
The phone I've been working on was a present for my sister is also used on Telecom XT, I bought it due to the spectacularly average range of phones available at the time through Leading Edge, hence my burning desire to remove the Telstra branding.
You can imagine how incredibly silly I felt when it arrived, she powered it up and it couldn't connect to XT. The thing that's made it extra frustrating is that I live in the UK and was originally working on the phone from here. The UK only has 2100MHz UMTS so couldn't test properly before posting. I've had to do all of this reflashing over the phone and with remote access from the other side of the planet!
Anyway, If you flash the most recent 2.1 RUU (not 2.2) then reflash the radio I posted, you can achieve a fully unbranded A3335 on XT.
You're fortunate to have 850MHz UMTS over there, No one offers sub 1GHz 3G here and it stinks! I used XT for a few weeks while I was back for Xmas and it was an amazing service (If you can get over the cost). You can't have service like that on any network here. Green with envy.

I was attracted to DK's rom because he made mention that the radio was left untouched (or optional to flash). So I'm fairly certain I'm running the original Telstra radio. I just can't be certain.
Would like to flash the 2.1 RUU and then back to DK again to get rid of the splash screen but for me, all that risk isn't worth the vanity. Like you, the phone isn't mine. It was bought for someone else but I'm responsible for its up-keep.

I'm all about the vanity! I even replaced its plasticwork to remove the logos from the case and posted it in a London issue Wildfire box (had one spare). There is not a single Telstra logo anywhere on this puppy! I think I'd be pretty comfortable in assuming that it's the only fully software/physically unbranded unit in the country- pretty satisfied with that!
The ROM and the Radio are two different components. You should never overwrite a radio by flashing just a ROM.
There's only two (maybe 3) ways you'll ever end up overwriting the Radio on an HTC phone:
1) Flashing an HTC RUU
2) Explicitly flashing a radio update with Clockworkmod.
3) It is theoretically possible for ROMs to include Radio updates but I've never seen a third party ROM contain a radio image. With maybe a small number of exceptions, ROM developers generally aren't going to risk deploying radios with their releases.
Of course you can easily find out by examining the contents of the META-INF/com/google/android/update-script file in the ZIP archive. If there's any mention of "Radio" in there then avoid it on exotic models like A3335
-strike off. the radio build might be different - there might be radios with partial coverage-

In a last-ditch attempt to get one garanteed delivery before the weekend, I ordered two xperia's, one from the UK and one from a US reseller (selling european X1i's nonetheless).
My question is this: my 3g band isn't supported (rogers) and I was wondering if the US version will use the same radio chip and what are the possibilities of getting an update which will enable this additional band (US1?)?
Thanks!

Are you in the UK or US ?
Which version of the X1 does not have 3G? or are you saying you don't get 3G signal where you are?

Answered several times already. The X1i does not have 850MHz UMTS. No one has managed to get a radio ROM on any HTC device to bring over the UMTS frequencies.
If you want it to work on 850 you'll need the X1a

so x1a rom on an x1i will not work to enable UMTS 850?? are there any links to x1a roms? I thought it wasn't even released yet...
Had this same problem with an omnia AND an n96 now its starting to get to me with the xperia since I really wanted this phone ;\
The OS rom has nothing to with the radio. It may add some options to radio settings, but it does not change the radio itself. The only practical difference is it may or may not make WM faster.
You can flash an X1a radio rom onto an X1i, but it still will not enable UMTS 850. The two radios are physically different (whether it's the microcode or the whole chip), and cannot be changed via software/rom flash. So many people have been trying with the Diamond, Raphael, etc, all unsuccessful; no reason to believe it will be any different with the X1. The only practical difference is it may or may not improve battery life and/or reception.
The X1a is the only one with a UMTS 850-capable radio chip, so if you need UMTS 850 your only option is the X1a.

Ok, so its a different radio chip... I remember the omnia i900 and i907 had identical radio chips as per specs but the former had the 850 disabled. Was hoping sony made the hardware identical and only differed on the radio rom.
Thanks for clearing it up

Really? I am running this rom and it has telstra all over it... pretty restrictive to be honest
that's because you have to put your devices serial number and it picks the best ROM suited to the device. I have "RUU_BlackStone_Telstra_WWE_1.21.841.1_Radio_52.57.25.30_1.10.25.25_Ship.exe" version if your interested? I'll provide a download link when I get home from work...

People are hoping that the Telstra model will work with North American 3G, and that there's some way to extract that functionality via software.
I have yet to hear a consensus on whether it's possible or not, though. One poster will say that without a doubt it's impossible, that lack of 3G is 100% hardware based, and another will say that is most definitely is a software/radio ROM issue.
I can't wait for some sort of verdict.

I'm not sure how or waht the difference is between 8282 and 8285. However, I have a 8282 bought in Australia from, I believe, a reputable firm. While it didn't come with the Telstra Rom it was advertised as being NextG compatable. I get full download speed (compared to my Diamond) and the H symbol is showing most of the time. I had always thought that the 850 compatability was more to do with Radio's than hardware. Especially when this phone has been sold in both markets for a while now. But maybe I'm just imagining the speed. The HD is not yet as good as the Diamond indoors out on the fringes of Melbourne where I live. But it is as good as most Nokias.
well i guess testing it wont hurt. i would want to give it a try too.

Yours originally is T8285 but they flashed the T8282 rom, thats why it shows that is T8282.
My phone is T8282 after i flashed the Telstra rom it become T8285.....but still not compatible of the NextG
The "H" is HSDPA and isnt 850 dependant. Just means that it goes to 7.2/2.0 which again isnt 850 dependant. NextG, like North America is 850mhz. You can have HSDPA on any 3G network (Optus, 3, Voda etc) which use 1800/2100 if im not mistaken?
8285 is the NextG/850 version. Nearly all Telstra-sold phones are 850 versions. Have to be very careful as they have different Radio Hardware
Hey guys
I have one of the Telstra Galaxy Tabs, and basically want to work a few things out with it.
First off I gather, with mention of all the carrier-specific or gsm/CDMA Specific ROMs, this has something to do with a radio or some such being included?
The Telstra "Next G" Network, which the Tab is used on, is basically 3g on 850mhz. Which of the types would this come under?
I have "Some" experience with flashing/ROMs/etc, namely on my Desire, so I am no expert by any means (Defo wanting to learn, and have learnt a lot from here so far ) but I do have a small amount of experience.
Thanks guys.
So, the community round here will answer questions for people that have obviously not bothered to search and ask the same stupid crap over and over and over, yet someone who has done a LOT of research, and is legitimately confused over a terminology issue (because technically it ISNT GSM or CDMA if you learn how the networks actually work) and just wants a simple answer to a simple question, just gets totally ignored?

GSM radio hardware is largely irrelevant, the hardware does the heavy lifting, the firmware doesn't care that it is, as long as it supports the right protocols.
Telstra uses a GSM/HSDPA/WCDMA network. In most cases, this is the case if your device has a SIM card.
The Tab sold here is essentially the standard UK version. If Telstra has an 850/2100Mhz HSDPA version then that could potentially be different. If you can root it using SuperOneClick, then run a complete firmware backup and try updating with another GSM firmware (e.g. RotoHammers JME) and see how you go. Before doing so, check that the device is unlocked, check if it can be rooted, determine the existing firmware/modem versions and the CSC version. It may be a custom firmware, it may not.
Your "LOT of research" was obviously fairly deficient if it hadn't ruled out Telstra using a CDMA network. http://en.wikipedia.org/wiki/Telstra

Your "LOT of research" was obviously fairly deficient if it hadn't ruled out Telstra using a CDMA network. http://en.wikipedia.org/wiki/Telstra

Well, The network you are referencing is actually the "Telstra 3g" Network used only in the capital cities around here. The network my Tab is used on/made for is the "Next G" Network. http://en.wikipedia.org/wiki/Next_G is the specific network. As you can see, it is technically not GSM at all, it is UMTS, and actually replaced our old CDMA network. So, this is where my confusion was coming in. But, if I have this correct, it is used as a basic term, meaning GSM = Sim Card and CDMA = No Sim Card (like our old CDMA network, phone itself is coded to the number/network type thing, which to be honest I didn't realise still even existed) yeah?
Cheers for clearing that up
As for the freqs, if I do a *#2263# the 3 WCDMA bands that are starred are 850mhz 1900mhz and 2100mhz. The GSM Fallback shows GSM 850 GSM 900 DCS 1800 PCS 1900 all starred. (Yes I did realise this before, I explained why I was confused with the terms hehe) The main band I have to worry about really is 850mhz though, on the WCDMA side, as you would have seen from the link.
Well, the device can be rooted with Z4Root at least, that is what I have used to root the device. This is exactly what I intend to try, once I am sure I understand everything. Does not hurt to read and re-read until one is definately comfortable with the steps, and I like to understand what every part is that I am doing.

Hey mate, i have a telstra tab, on original firmware (jj3 i think) i would only ever get 3g..
After flashing rotos jme + the phone.bin, i now get hspa most the time.
Rotos firmware works perfectly, but as always backup everything

Just to be 100% sure, that is the one here? And you are on the Next G Network? (I assume so with the 850mhz band etc, I thought this would work, but doesn't hurt to be sure I am looking at the right one you are talking about hehe.)
I can confirm the original firmware is JJ3, with phone calling capabilities etc.
Of course, backups always come first, always.
Thank you heaps for the info.
Also, if there is any part of this device's firmware etc that would be helpful in any way to the devs, I would be happy to extract anything needed from a rotobackup or whatever. I won't be flashing it straight away, and definately not before a full backup anyway.
(edit:spelling)
HI mate, how did you go with the flash?
I'm thinking of doing this as well, but just want to see if anybody has noticed any difference (for the better that is).
I have n Australian telstra tab on the next g network, and flashing a rom was the best thing I ever did
swyped from a galaxy far far away...
Hey, not trying to hijack this thread, although I too just got a SGT for the wife from Optus this morning and playing around with it and keen to hack.
Mine came with the following
PDA : P1000XWJJ4
PHONE : P1000XXJID
CSC : P1000OPSJJ3
Build Time : 2010.10.16 20:35:06 KST
Changelist : 639474
Firmware 2.2
Kernel Version : 2.6.32.9
Keen to know what is the best rom for us here down under, i'm, off to root me SGT.
Cheers

For the optus tab any euro rom will work i started with the modaco rom and kernal then moved to the overcome rom and kernal. Both ran prefectly just make a backup to be safe.

Thanks heaps!
I did try to root it, and used OneClick, when 1st time round it sort of worked, then I tried it again with the rageagainstcage option and busybox installed this time round.
Next is off to grab overcome rom, will try and do a backup but only have a 1G card atm
Again thanks and sorry to the OP for the hijack
PEACE

I travel a lot and am sick of the 850MHz/900Mhz limitation on the HD2 models. I currently own a UK 850MHz HD2 and was thinking of buying a Telstra 900Mhz HD2 on ebay, then maintaining both models and taking the appropriate model to suit the networks in the location I'm travelling to. To make this practical I need to know the process and tools (if they exist) to easily image all the apps and files from one unit to the other.
My current T8585 model is running stock HTC UK ROM. Would I need to flash the Telstra models ROM? Can the T8585 stock ROM be simlpy flashed to the Telstra model even though the Radio hardware is different ?
Any info appreciated ...

I'm assuming you're talking about 3G (because all HD2s have quadband for voice)? If you are, I'm sure you got the bolded part mixed up.
Yes - 3G. My current T8585 model supports 900MMHz and 2100MHz, the Telstra model supoprts 850MHz and 2100MHz.
No, I don't think it's safe to flash an hd2 with a stock rom not meant for it.

Yeah, the 850 band is on the telstra t9193 for 3g, while the 900 band is on t8585 euro models.
Anyways, yes, you could get both models and flash them both with the same custom rom (you would have to put hspl on both, I would think, otherwise each model can only use stock roms prepared for each model, and there might be slight differences.)... then just use a back app to back up one, and restore the backup on the other.
I have recently purchased a 32A Three branded HTC Magic (Hutchinson Australian Phone Providor).
After a bit of research, I have noticed the Magic was released with 850mhz support from Rogers in Canada. Most other releases sold in the US, EU, UK etc did not support this band.
As Three roams on Telstra's 850mhz network, I was wondering if anyone who owns a Three HTC Magic can verify whether the Three version does? (I am aware the Vodafone 32B version doesn't)
If so, when I plan to root the phone and load a new ROM, will I lose 850mhz support if i upgrade the Radio firmware?
If that is the case, what is the best and/or newest Radio I can use on the HTC Magic that supports 850mhz? (as I need the ability to roam).
Eventually I would like to try one of the Gingerbread or at least Froyo releases on it.
Any advice is appreciated.
