[Q] How do I choose a rom? - Desire Q&A, Help & Troubleshooting

I've recently upgraded my 2.2 to 2.3.3 gingerbread, but the phone's identity is now A8181, the international version. I bought the phone as A8182, which would be compatible with North American networks.
How would I choose a ROM to revert to that's compatible with the local networks? And would 2.3.3 still be compatible, even though the phone thinks it's A8182?

Does the network works? Then no problem.
What network are you on, BTW?

no matter what rom you are using, it won't afect the network that you're phone is compatible with because that is built into the hardware. the rom can change what the software tells you but it will work the same as before

I'm with Rogers (canadian), however I haven't had the chance to use 3G as I don't have a data plan, and the phone was bought unlocked. Wifi works, sms works, mms doesn't, but that needs data.
Would this mean that I can use any rom with my phone and not have its functionality changed in any way?
Which rom would be appropriate if my phone was bought in Canada? The phone may have been supported in the past by Telus.

your desire should be able to work with telus or rogers networks in canada. i'm using an australian desire which is a 8183 on fido but i stick to wireless instead of paying for data. however, the 3g frequencies that the 8182 and 8183 use are compatible with canadian carriers.
yes, you can use any desire rom and it won't affect this compatibility because its built into the hardware. whichever rom you use is up to your personal taste, it doesn't matter where you live

If you have the T-Mobile USA TP2 it's a GSM phone, and if you want to flash a custom rom it should be chosen from the GSM ones.
As for which ROM is best for use in Europe, it doesn't matter.
Edit: I assumed you're talking about an OS-ROM...but if you're talking about a radio-ROM then maybe some work better than others in different locations.
But, as far as I know, the TMo USA rom won't be able to access 3G signal in Europe because its radio hardware uses different frequency/bands for 3G than is used in Europe. It will work with regular GSM bands, though.

As i saw here, few people were using 3G in Europe (Turkey and Germany) without any problems.

A T-MoUSA-branded TP2 in Europe and using a 3G data connection? If that's true, I'd be glad. I'd like the option of high-speed data on my TMoUSA phone while over there...

I'm getting mine, from USA, in a few days and will keep you informed
It works on every network I tried so far.

Desire A81829 (Telus) for use in Europe?

I have Nexus One but I'm not fan of those 4 touch buttons
and I'm considering getting A8182 If I unlock the SIM I'll be able to use
SIM card from European providers for voice but I'm confused about data.
My understanding is that the Radio is partially disabled and I would need to unbrand the phone. If I do that will it work the same way as Nexus ?
Thanks
TELUS desire only has 850/1900 umt bands so 3g wouldn't work since you need 2100/900

That sucks Do I have to unbrand the device to get any data in Europe ?
How slow is EDGE ?
Thanks

....Other than that, and branding for Telus, the phone hardware is identical. I should also mention that the Telus branding also disables the EDGE/GPRS data because Telus and Bell do not use it - stupid move since that means all US/CDN travellers going to EU will not have data since the freqs are different for 3G and 2G data is disabled.
However, there is a way around that by unbranding and updating to Froyo 2.2 which will remove the block for EDGE/GPRS and offer more features.

[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] 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] GSM and CDMA

So I'm in Canada and I just got a Virgin mobile SIM but my phone is telling me network is unavailable. Phone (Desire bravo) is unlocked, cm7 etc. but after doing some looking I noticed that Virgin operates through the use of Bell's network which is a CDMA network. I assume this is the problem because there is nothing else I can think of.
Is it possible to flash a different rom that would allow me to switch to CDMA or is it hardware related? Also am I on the right lines or should this whole CDMA GSM thing not matter?
Cheers

Hardware related to CPU, you'll need a CDMA phone or change networks...
