[Q] do I need to flash my radio to use TP2 abroad?

Hi there,
I'm totally confused as to what I need to do to get my Touch Pro 2 (currently activated on Boost CDMA) to work abroad, specifically Canada.
It is flashed with Energy ROM, Reference version.
Do I need to do a Radio flash? Do I need to tweak some settings? Both? Neither?
I'm going to be in Canada for 3 weeks and plan to use either Rogers or Fido's GSM Pay as You Go (already have the SIM cards), or Telus's CDMA Pay as You Go.
I've read the FAQs and generally understand that this is possible -- just not clear the route.
Thanks,
Simmy

The biggest problem with Canada is our carriers don't want people coming in and using their networks without paying for it, and that usually means your first born here.
The hardware problem is, the TP2 will not work on the frequencies in Canada that Telus has used for the HSPA / 4G network. And using the current CDMA network is not possible either because Telus and Bell will not allow you to put branded phones from other companies on the old network and CDMA systems don't use SIM cards. So if your planning on bringing the TP2 up here I think you may be out of luck.
I took the TP2 to Ireland and was able to use the frequencies there on the O2 network, but to do that I had to unlock the phone and as i have the "world edition" with the SIM card slot once unlocked it worked over there no issue, and returned working over here with no SIM card in it. But again this is a frequency issue and telus tells us it won't work.
Now if when you get here, and you plug a sim card in and it does work, please share, because it means we can manually add frequencies and hook to both the old and new network. And some of us with the original unlimited data contracts (no 10 gig cap) would be really happy to know this.
As for Rogers, i can't tell you. I don't know if they have ever had the TP2 and have no clue what frequency they are using for their phones, though i'm sure it's similar.

Flashing the radio does nothing to add radios or affect your ability to connect to the network while abroad. Its usually just done to improve reception and/or battery life.
You will need your phone SIM unlocked. Then, as the post above suggests, either putting in the SIM works, or it doesn't.

Thanks to both of you for your reply.
So the TP2 won't work on any Canadian CDMA networks, but since it also has GSM, if I stick a Rogers or Fido SIM card in it, it *may* work. In fact, I believe it *should* work. I'll let you guys know how it goes.
And thanks for answering my question re: radio ROMs, Redpoint -- that's what I thought, but was still confused about.
So, with respect to unlocking, is the Olipro page that charges 11 pounds / 14 euros / $20 my best/cheapest option? (unfortunately, i can't link to it here because I'm a new member)
Thank muchly,
Simmy

The device should have no trouble connecting to a normal GSM network in Canada. The Canadian GSM networks use the GSM-1900 and GSM-850 bands. The CDMA Rhodiums use a quad band frequency that spans all of 850/900/1800/1900 MHz channels. You should have no problems in Canada. Enjoy your trip.
You do not need to flash a new radio to have it work in Canada.

[Q] G2 3g on AT&T?

You will only be to access 2G/edge data speeds, no 3G connectivity since AT&T uses different 3G bands.. assuming you are currently using a T-Mobile G2 with the carrier T-Mobile... :?
You won't have any signal issues unless AT&T has horrible coverage where you live.

you will not change anything hardware related... you just unlock/root your phone which allows you to modify hardware and software related things. But if you don't touch the antenna software then nothing will change
@CaliBoyPhillip; when I was in the states my phone switched from AT&T and T-Mobile all the time (roaming) and still had 3g reception, the phone supports most frequencies.

no im currently using a Aria with AT&T but im getting the G2 or the G2X tomorrow. and ok so i wont lose my 3G?

G2x will work with At&ts 3g/4g. As for G2 I was told it doesn't support the 3g/4g from at&t. Remember the buy out isn't final yet.

hmmm Interesting... it was prob due to the reason that you were roaming but if he uses an AT&T SIM on his SIM unlocked G2 from T-Mobile, he won't have 3G access I think... The G2 runs on 850/900/1800/1900 for edge and 1700/2100 radio for 3G data, meanwhile AT&T operates on 850/1900 for EDGE and 850/1900 for 3G.... not compatible !

THis is correct. The G2 WILL NOT work with ATT 3G. If you want 3G you need to purchase the NAM (North American Model) of the Desire Z. It is sold in Canada on the Bell Network. You can find it online unlocked and unbranded and it WILL work on ATT no problem. It is going to cost you though, 450-550 depending where you get it.

Same reason iphone won't connect to tmobile 3g...amazing people still don't understand this

ok so stupid question but im gonna ask it anyways lol is there anything that i can do to make it work with 3G if i dont want to buy the desire z?

Not unless you know how and which chipset to replace on the board. Ie not possible.

Nope, the phone's hardware is what decides what bands it can use.

Get a desire Z from rodgers Canada the 3g bands are the same

To bad radio isn't software
It's to bad that phones don't have the radio frequencies programmable in software (much like an fm radio). Is that even possible?

[Q] No data on T-Mobile G2

I got this really cheap T-Mobile G2 in the US which worked perfectly alright and brought it to to my own network overseas. I know the handset uses 3G on a totally different band but I believe edge connection should work, right?
Anyway, I unlocked it using the downgrade method. Then I installed CM7. I put my own sim card and it does pick up signal and I am able to make and receive phone calls but there is no EDGE. I already set the APN options correctly.
Any thoughts?

You sure the APN info is correct for your carrier? Ability to make calls, but no data are pretty good indications of wrong APN.
Yes, as long as the phone has the same GSM bands used by your local carrier, and you are unlocked, you should be able to get data via EDGE.

Isn't there a reason the us has G2 and the rest of the world has desire z? Aren't the bands different between the 2?

Just different bands for 3G. Your G2 has the proper GSM (voice and EDGE) to work in most parts of the world.
And the G2 name is just T-Mobile's branding and to signify the vanilla (no Sense) ROM. The Canada, Europe, Asia versions of the Desire Z all have different bands from each other.

Completely sure. Used the same sim I use in my main phone which is also android based. Could it be a radio issue? I was tempted to flash a new one but since Im not that familiar with this particular phone I don't feel like messing up, especially when all I want is the phone to work so I can sell it.
BTW, anyone interested PM me - although I believe I shouldn't post this here.

[Q] Ace or Inspire?

Hi my plushies
Anyways. I just got a Desire HD! YAY ME!
Being a Desire owner for 2 years and seeing a lot of great development on the HD, i'd give it a go. So far seems good, though i like the AMOLED a bit more imo
So my first boot after getting it from retailer, it boots with T-Mobile logo. That means its from USA right? Is my phone then an Inspire or a Ace? Afaik, the Inspire is the american version?
The weird part is, i got the T-Mobile one because the other one (a danish one WWE), was send for repair and i recieved this instead.
Will this affect anything? And how the *** do i figure out of its an Inspire or Ace?!
**Btw, i did do my search first lol
**Is it on the bootloader? I saw an "Ace" in there, but wasn't sure if everyone DHD had that name
*2. edit* Lol apparently i've used the wrong terms. So, Desire HD or Inspire (Apparently their all Ace (As in vendor Ace, like the Desire -> Vendor Bravo))

Inspire is the 4g version DHD was not.
also check the "full" spec list at the bottom of this page
http://www.differencebetween.com/difference-between-htc-inspire-4g-and-vs-htc-desire-hd/

I've got a german t-mobile branded phone so i'd never be sure where it's from
but yes: DHD is the HSPA version, Inspire 4G is the 4G version (LTE? HSPA+? no clue)

My phone is an American inspire that i bought unlocked online... its actually an ATT phone and not tmobile. If your phone is a Tmobile then its def not american but probably from some other countey instead. Another way to find out is by seeing if you get access to 3g in yoir country. Because att uses frequencies that are different from most other countries around the world, the american Inspire doesnt get access to 3g data in most countries. Apart from that its practicaly the same phone hope this helpzs

There are basically 3 versions of the Desire HD.
First is the European/Asian version. It is model A9191 and has high speed data bands of 900/2100. It can be branded or non branded but they are all the same physically. If it says T-mobile on it then it is a European version branded to T-mobile.
2nd is the Telus Desire HD from Canada. It is model A9192 and has high speed data bands of 850/1900. It has no logo denoting it as a branded phone. It also has a second mic by the camera flash used for noise reduction.
3rd is the Inspire 4G from ATT in the USA. It is also model A9192. Physically it is exactly like the Telus Desire HD except it has ATT branding logos on the phone.
All 3 phones are HSPDA compatible. All 3 have the same size memory. All three have the same LCD. In terms of getting at least 3G, if you live in Europe you want the A9191. The A9192 is mainly for North America/parts of South America and can be used in parts of Australia on the Telstra network.

Hi I currently have a A9191 running CM7.2.
When I purchased this phone (in Australia) I was originally on the Vodafone network & I'm now on Telstra NextG (850) - but for high speed data it can only get the "3" network = 2100.
I wanted to know if it is possible to load on the A9192 baseband to "activate" / change to the high speed data bands of 850/1900? Or if there is any other mod to do this?
Or is the physical hardware of the A9191 only capable of the high speed data bands of 900/2100?
Any help or advise would be much appreciated

Thanks Teichopsia,
Looking at this thread, it looks like he was trying to get 4G (inspire4G) out of a 3G device, which I'd say is even harder than just switching bands.
But it doesn't mention anything about the A9192 vs A9291.
Even Qualcomm's site doesn't list a A9192.
I agree it does look like a potentially hardware thing though - i.e. potentially different radio hardware / antenna / firmware... but I don't specifically see this detailed anywhere. Looking to see something that says it is different physical hardware.
The theory I'd like to validate - both Desire HDs use the same MSM8255 chipset, & perhaps you can make a A9191 to a A9292 with flashing the right firmware.
Going to reply to the thread you sent to see if they had any further luck.
Kind Regards,
David.

[Q] Unlocked Desire HD won't find network/get signal

Hi all,
I was hoping someone could help me with a problem I've had with my HTC Desire HD. I've unlocked the phone (but not rooted) having moved from the UK to Canada and wishing to use a Canadian sim card in my phone.
However, I don't get any signal or any network with my Canadian (Virgin) sim card. It accepts the sim card and allows me to use the phone, but I get no signal whatsoever. I've tried taking the battery out and waiting 30 minutes, and have gone off and onto airplane mode to attempt to get it to connect to a network, but nothing.
Is this something that rooting the phone could help with? Is the fact that I'm in a different country anything to do with it? The only network it can even find is called 'EXT' but it won't connect. Anyone able to help?
Some extra info:
Model Number: HTC Desire HD a9191
Android Version: 2.3.5
HTC Sence Version: 3.0
Software Number: 3.13.61.5
Any help would be so greatly appreciated.

I'm going to cover the obvious first, you put the sim cover back on right? Its needed for the antenna

Yeah, the cover is back on.
The other strange thing, is that the phone recognizes a Canadian number in the Phone Identity.
I've tried a different Canadian sim card, and that works. The sim card that is not getting signal works in other phones too.
It's all a bit odd.

Sounds like its the sim card is the issue. I had a similar encounter a while back, my sisters tmo sim wouldn't work but my brothers tmo would. So it could be just needing a new sim or the carrier might have some kind of lock on their Sims. Just because a phone is sim unlocked d doesn't guarantee any sum will work its kind of a trial and error sometimes

Thanks mate. Perhaps I'll take it down to where I got the sim card, see if they're able to help me out or not.

Desire HD from UK will not work at all in Virgin Mobile Canada.
VM Canada as being a virtual operator uses the Bell Mobility Network.
Bell Mobility works in LTE band and 3G but 850 MHz and 3G 1900 MHz.
Desire HD does not have those bands in 3G (only 900 and 2100 MHz).
Desire HD has 850 MHz and 1900 MHz band but only for GSM 2G. But Bell Mobility does not have GSM network. Only 3G and LTE.
Here is the list of the mobile operators in Canada. You can use SIM card from any operator which has GSM 850, 900 or 1900 MHz or 3G 900, or 2100 MHz.
http://maps.mobileworldlive.com/network.php?cid=88&cname=Canada
(but please check if any of those compatible operators have any coverage in your area. From the network you found it seems that Execulink Telecom has the coverage but it will be only 2G).
You may see people using there Desire HD in VM network, but if you take a closer look, this is actually HTC Inspire 4G which is basically Desire HD but for the North American market with LTE and different band radio modules.

Hmm learn something new everyday. Didn't know virgin didn't have an 2g network, that explains the op issue

To be completely honest, Bell Mobility has a 2G network, but it's CDMA (also with Ev-DO) so completely another story, not related to Desire HD or Inspire 4G
