Hi everyone,
I bought my T-Mobile G1 from the states about a year ago, when the G1 was exclusive to T-Mobile. I am currently using my G1 on the Rogers network. I knew I would only get EDGE and won't be able to get 3G on my phone but I was content, because I wanted the G1 so bad!!!!!! Rogers operate on 850/1900Mhz and the T-Mo G1 runs on 1700/2100Mhz. Now since Rogers are selling the HTC Dream, it changes things for me. I want 3G!!!!!!
So, to get down to the point, I was wondering if there is a way for me to flash my T-Mo G1 with the Rogers HTC Dream image/firmware/radio so I can get 3G on the Rogers network?
My G1 info:
DREA100 PVT 32B
HSPL10.95.3000
CPLD-4
RADIO-2.22.19.26I
I know there are a few posts about this, but all the posts died.
If there is a existing post about this inquiry please point me to the right thread.
Thanks
good dream!

I'm fairly sure that's a hardware limitation, and not something that software can fix. People have tried flashing the Rogers radio on tmo dreams and ended up with bricks (shockingly >.>).

i need to flash an htc g1,
and i dont get any software to do,
the matter is that it is resetting,
i already hard reset it, and its the same,
what do you sugest?
I think this is very possible. I have in my possession a G1 from T-Mobile UK which was reflashed with the US ROM and it works swimmingly on 3G here.
Correct me if I'm wrong, but T-Mo UK's 3G is on 1900 MHz and US is on 1700. This would lead me to believe that the radio IS capable of operating on all current UMTS frequencies.
Sorry fine sirs,
but you would have to find a Canadian frequency version of this and install it in your phone.

Why don't you just try it and find out? If it doesn't work, then just flash back your original image.
I don't think you need to change the antenna. The radio chipset is what determines which frequencies you can operate on, the antenna is basically a glorified piece of wire. Think about this: the G1 in the USA operates GSM/GPRS on 850, 900, and 1900 MHz, as well as UMTS on 1700 and 2100 MHz... all with the same antenna! You don't need to change it to operate on Rogers.

Dude go back and read my last two posts... I have "converted" a UK G1 (read: no 1700 MHz band in the UK) to work on T-Mobile USA's 3G. The only "conversion" I did was installing the US ROM. No antenna swap, no mainboard swap, did not open the phone whatsoever. Unlocked and the flashed. Done.

So you didn't get 3G before, and after flashing a "US" ROM (ROMs are region defined?) you have 3G? Hmmm

No, that is not what I said. When I received the phone, which was a UK model with the T-Mo UK ROM installed, I immediately unlocked it, rooted it, and reflashed with the US ROM. I did not test it before hand to see if 3G worked because the phone was locked to T-Mo UK and I only have a T-Mo US SIM card. I never said that it was not capable of 1700 MHz before the flash, only that the hardware was capable regardless of where it was bought.
And yes, the T-Mo UK ROM is different than that of the T-Mo US ROM. I am not a programmer, so I do not know how fundamentally different it is, but it most definitely comes with different apps and customizations, as well as APNs. Also, if you remove the battery cover, the UK model has a different part number than the US model. Beyond that, it is shown as an 'unrecognized device' in T-Mobile USA's system, whereas the US model shows up as an HTC G1. I believe that this is only related to the ESN, but the internet only works on it with the Android data package- it would not work on the Sidekick plan. I don't know if it's network-side or phone-side, but something is identifying it as an Android device.
Anyway, my whole point to the OP was that his phone should have the proper HARDWARE to operate on either Rogers' or T-Mobile's 3G, and that if something was preventing him from doing that now it was most likely due to the software on his phone.
The only part of a ROM that could change this would be the radio

Bump: anyone try this out yet? I'm curious... It seems hard to find the Rogers standalone update though, you might need to unroot then reroot to do this.

Does anyone know if the hardware is different from the US G1 to the UK G1? I know the US model uses the 1700 and 2100 bands for 3G, while the UK model uses 2100 only. Is this due to a physically different radio chipset, or is it strictly a ROM change? Could one flash a US ROM onto a UK G1; and would it work on 3G in the US?
Thanks in advance!

I'd expect the 3g radio/chipset would be the same in them. If you take your UK G1 to the US I would imagine it would work on the US 3g network fine.

There is a hardware difference, extra antenna/amp chip. The T-mobile network in the US uses both 1700 and 2100 bands to establish the 3G voice/data connection. You'll be able to get 2g for sure, but not 3g. T-mobile uses 1700 band for up and 2100 for down stream.

I think when the op said the Dream uses 1700 and 2100, he meant UMTS Bands IV and I respectively. The Dream communicates with T-Mobile USA using only Band IV, which is commonly known as UMTS 1700, even though it does use 2110-2155Mhz for the downlink. More info here.
All the USA T-Mobile APNs are installed on the UK version, are there any 1700 ones listed?
I deleted them all or I'd check myself.
I have both the US and UK versions of the G1 in hand. I have looked at the list of US APNs, but I'm not really sure what to look for. They all specify epc.tmobile.com, but beyond that the numbers don't mean anything to me. Can someone tell me what to look for?
As far as the radio chipset, I have the service manual and I'm willing to disassemble the UK G1, just not sure what to look for. I'll be glad to take pictures along the way.
Externally, I have found a few differences in what's printed under the battery-
US model: DREA100
UK model: DREA110
US P/N: 99HEW038-00
UK P/N: 99HEW042-00
Of course, the difference in numbers could lie in the firmware.
Thanks everyone for the input thus far, any other advice you can offer is also appreciated!

Given the poor 3G coverage on T-Mobile in the US, why would two powerful phones such as the Nexus One and HD2 be relegated there? It is as if they are sabotoging themselves by being on T-Mob. (This paragraph was rhetorical).
My X1i is on it's last leg (screen blank in landscape and microphone not working) and I want to replace it. Currently, HD2 is the only thing that is appealing. I think I am going to hack one of the overseas models to work on 850MHz 3G on AT&T and forego waiting for the T-Mob model. Thanks XDA.
Hopefully, someone will make a step-by-step sticky on how to get the HD2 working on AT&T 3G USA.
1. Hard-SPL
2. Flash custom ROM
3. Insert SIM
That's what I did to get it working on Telus' 850mhz 3G. I remember the dude who made the huge thread about being the first in the US with a T9193 saying it was similarly easy.
If you just put your AT&T SIM in, you'll be able to send/receive texts, and make calls, but Telstra has the data connection settings locked down pretty heavily in the stock ROM...
OK, yeah, I was just looking through some of that thread. I thought it said something about changing or not changing radios. Is this already taken care of inside the custom ROMs ?

You need to make sure that the HD2 you buy has HSPA/WCDMA 850 MHz (not just GSM 850 MHz), because most do not.

Yes, based on what I am reading, getting the Telstra model with 850MHz 3G band should be compatible with 850MHz 3G AT&T in the U.S.
The designated-"U.S." model is designed for T-Mobile 3G (1700MHz or 2100MHz)

I fixed that for you -- phones won't work on T-Mobile 3G without BOTH 1700 and 2100.
Hello if someone could help me with my 3G connection inquiry, I would greatly appreciate it.
I bought this phone unlocked from Hong Kong and brought it back to Canada. But the 3G connection through Rogers won't work. I am able to connect to edge (When i pop in my sisters sim card which has a data plan, as my sim card currently does not have a data plan).
I talked to Rogers and they said that everything is compatable (After mentioning the phone frequencies and speed capabilities) and that the only reason 3G isnt working is that I have not configured my phone properly for 3G and at this moment it is configured for 2G (Edge).
I then contacted HTC and they said the reason was because "for the Rogers network, their 3G signal is operated on the 850/1900 MHZ band and the Touch HD2 operates on the 900/2100 MHZ band." Could this be the reason? Will i never taste the pleasures of a 3G connection?
PLEASE HELP!!
since you have bought it in hongkong most probably you have the asian version. It comes with 900/2100 MHZ bands and as you mentioned ROger needs 850/1900 frequency.
You could also get Telstra version from Australia and unlock it as it has 850/1900 frquency so that you could get 3g. But not possible on the one you already have.
Yea its the frequencies. When I take my phones abroad, I always check what frequencies the country has. If the frequencies don't match, the phone won't work in terms of placing calls, 3G etc.
is there a way to unlock ?

Hi,
Seeing as most heroes including mine are on the GSM band of 900MHz and not the 850MHz that for some reason Telstra decided to use in rural areas, is it possible to flash another radio to 'unlock' (right word?) the 850MHz band to allow HSDPA speeds for me as opposed to the Edge network?
If this is possible, does anyone know where to get the radio for this?
TIA

its not possible, as the hero radio hardware itself is not capable of 850mhz umts/3g band.
Unfortunately, theres no way to simply 'unlock' it, as it doesnt exist.

So very wrong! Are you serious? You know there is more than one version of the Hero right? Euro, NAM, AU, and CDMA. NAM and AU have 850MHz UMTS.
What about the Telus or Telstra hero's? They use 850 in Canada and in Australia. Why would those carriers sell the Hero if it doesn't have the correct freq for their network? I have a Telus Hero and it has 850UMTS. Seriously, if you don't know the answer, don't say anything.
In my experience the best Radio file for good 850 Reception is the 09.26 radio. If you search you will find it.
Here it is...
I tried posting the radio file but it is too large for XDA. Sorry.
regarding to the HTC site the hero has those freqs:
Code:
Quad-band GSM/GPRS/EDGE:
*
850/900/1800/1900 MHz
and I think these should work with all radio versions.
http://www.htc.com/europe/product/hero/specification.html
but it does not have FM.
I forgot to mention that my Hero is not a native Australian Hero but a UK Hero which means the UMTS frequencies are: 900/2100 MHz.
Will flashing another radio give me 850/2100 MHz? (is the original question I should have asked) Telstra run 850MHz in Rural areas and 2100MHz in metro areas. Why on Earth can't Telcos all run on the same frequencies!?

No, it won't. The HW says 900/2100, SW won't change that.
Because they're douches. Mine is also the 900/2100, else I would've suggested a swap. :V

as has been made clear, he has an Australian Hero which only has 900/2100 3g bands. I probably should have stated I was assuming that when I posted my comment.
The Hero was never sold via carriers in Australia, only through electronic retailers, hence Telstra never actually sold the phone.
Hello,
I'm very sorry if the question was asked before, didn't dig to it.
If I buy a version GT-I9020 or GT-I9020T that works in 1700 Mhz UMTS rage will I'll be able to reflash it later to GT-I9020A to make it work on 850/1900?
I'm thinking about buying it but this is crucial for me, as I'm moving to a different country in a year and I need 850/1900 over there.
Thank you for you help!

You really, really, really, really need to do a lot of reading before you even dream of flashing anything.
Your question is analagous to asking if a software update will allow your microwave oven to run on gas.
A cellular phone contains a hardware radio that communicates with the network. Although people here and elsewhere often refer to a flashable "radio", what they really mean is a radio driver. Nothing you flash will ever change the hardware. Verizon and Sprint phones will remain CDMA (unless they also have a SIM slot, as a few do). GSM phones will remain GSM and will not be capable of changing their frequency via software.
