Hi guys,
I'm really new to this, so please excuse me asking basic stuff.
I am an iPhone user and I am familiar with linux and flashing of a huge number of different devices (Nokia, Xbox360, Xbox, Siemens, PSX...). I am living in the US, but my girlfriend lives in Germany. What I did is, I got her a AT&T locked HTC Aria for x-mas. I am aware of the difference between rooting and unlocking, but still I have some basic questions:
1. Do I unlock the device before or after I root? Does it make a difference at all?
2. As the phone is meant to be used in Germany, which (as unbranded as possible) image should I use? Can I use liberated R012/FR006 or doesn't this work in Europe? Could I use the Gratia Image?
2a.) Shall I go for FroYo or rather stick with Eclair?
3. Does the change/upgrade/renew of the image affect the unlock in any way?
4. Can I unlock the phone with an app or similar, when the device is rooted or do I have to pay for the unlock code?
Thank you so much in advance, I really appreciate your work and your help,
Tim
P.S. I used the forum search and did not find an current answer to my questions
Maybe someone can also give me some advice on what to read, just to understand the basic stuff.
Thanks!
Hi, I'm not an expert, but here is my experience in case it helps:

I unlocked first with HTCSimUnlock.com - had to pay the extended search fee.

I used liberated_aria_R012, then the "update": la_www_update_R002_signed referenced in the first post in his thread. However I can't get Titanium Backup to remove the bloatware social networking stuff like facebook, ppok, etc., as others recommend. I also couldn't remove them using the complicated "SDK" method as the "ADB" can't find the phone. I don't know whether this is anything to do with the version of the ROM (I know there are more recent versions), but I got fed up after 6 hours trying, so now my wife (it's her phone) just has to live with the clutter
2a.) Shall I go for FroYo or rather stick with Eclair?

The version I have is Eclair - works fine, not noticeably faster or slower than the stock ROM.
3. Does the change/upgrade/renew of the image affect the unlock in any way?

Don't think so - not for me anyway, I have used many network SIM cards in the UK, US, Poland, Macedonia, Qatar, UAE, Italy (haven't been to Germany recently, sorry!)
4. Can I unlock the phone with an app or similar, when the device is rooted or do I have to pay for the unlock code?

I think I know how you feel. Even after a few years of familiarity with custom ROMs for Windows Mobile phones, this business of android "rooting", "ADB-ing", etc. and commands that look like Unix, it all sounds a a bit intimidating, especially since the "flash menu" entries aren't quite as the guides say in respect of the USB connection, bot following this thread about "unrevoked" is the way I went.
Good luck
I don't think the rom you use will really matter, so I'd recomnd (if you don't mind running on the experimental side) the cm6.1 roms.
For unlocking, just call att and tell them you want to use it for international travel. They'll give you the code for free. I did this with my old blackberry 9000, took a few weeks, but it was basically 0 hassle. My experience was with an off contract phone, but I understand it works with on contract phones as well, someone correct me if i'm wrong, but theres no harm in trying.
hi
i would suggest to wait for gratia in europe (i think it should be released in some days)
i use a aria in austria (ordered a week before htc pronounced that gratia will come to europe ) - works fine but only edge not hsdpa is working for data connection (due to differenze frequences in us & europe)
otherwise no problem with that greate phone

I get HSPDA with my wife's AT&T Aria, in all the European countries & Middle Eastern I visited and except rarely when in the UK and she doesn't get an Orange signal (her carrier), and it switches to T-Mobile's GPRS. Not sure if Austria's different, or may be the APN settings are working, but in my experience HSPDA is possible with the Aria phone hardware.

I tried that but they refused as I wasn't the original AT&T owner (got it from eBay). Maybe you'll be luckier.
There's a helpful looking video on youtube by the way: http://www.youtube.com/watch?v=rjgg__m-KHc. Although it doesn't look like an AT&T phone, it seems to cover all the steps.
@kc1: are you sure?
i would be happy it it would work!!!
when you look at the specification at htc.com for aria and gratia you will find
gratia
* HSPA/WCDMA: 900/2100 MHz
* GSM: 850/900/1800/1900 MHz
and aria (us)
Dual Mode UMTS/HSDPA/HSUPA (1900/850MHZ) &
GSM/GPRS/EDGE (Quad band 850/900/1800/1900MHZ);
and i tried at with different carriers (orange, t-mobile, a1) - no change to get even a connection when changing into WCDMA mode...

@Dopsi:
Like it says in the Aria specs you've quoted above: "HSDPA". When I'm roaming in Europe & UAE, etc. I get an "H" and a fast connection if I turn the data on in most cities/countries. In other places sometimes "3G". I don't know what frequency Austria uses for it's networks (Due to be back in Salzburg after x-mas so will try it next month.), but I do know that in the past when I've only had a "G" or "E", it has been if I had the wrong APN settings. e.g. with O2, if you pick the "MMS" or "Wap" APN instead of the o2web, and similar for T-Mobile
thanks
Hi everyone!
First of all, I want to thank you for all of your advices. I have not been around for the last days, so I couldn't reply earlier. I read your answers and they were really helpful to me!
As I mentioned before, I am a total newbie when it comes to Android OS or HTC handsets. The HTC homepage and many other forums say, that the aria won't operate on the European UMTS standard. Is this due to a hardware limitation or might this be fixed by using a different rom (like the one of the gratia)?
If this won't be working, is it possible to use skype on mobile with Edge?
Thanks again, have a great day!

I would also like to know how you got HSDPA to work in europe. I have a AT&T Aria wich I'm trying to get to work with 3G/HSDPA in Sweden. It's unlocked through the same site you used and has the "liberated_aria_R012" rom with the "la_www_update_R002_signed" update. I have tested several different APN settings but I'm still stuck with Edge. I've read that the Aria's hardware doesn't support the 2100/900MHz band but your experiences says otherwise. Please bring some light to this problem
Any updates on that? I really would like to operate the phone in europe using full 3G speed!
Maybe it's possible to reflash the radio image?

The AT&T branded Aria does not support the 900/2100MHz bands for UTMS. Only 850/1900, so you probably won't be able to get 3G. Flashing a new radio will not work because the frequencies are in the hardware, not controlled by software.
*grml* Stupid USA!!! Can't they just use the standard of the rest of the world?
Thanks anyway, maybe Edge is fast enough for my girlfriend's needs.
Do you guys think it is possible that some major cities have installed some antennas for the US standard to make the mobile internet faster for visitors? This would explain the experience of @Dopsi.
Thanks for your replies!

I just reread Dopsi's replies and he said he only gets EDGE, not HSPA despite all of the different settings he has tried.
Ah, right, it was kc1 saying:

Hello guys,
actually there are two types of HTC Aria:
HTC Gratia (HTC Liberty):
GSM850, GSM900, GSM1800, GSM1900, UMTS900, UMTS2100
HTC Aria A6380 (HTC Liberty):
GSM850, GSM900, GSM1800, GSM1900, UMTS900, UMTS2100
HTC Aria A6366 (HTC Liberty):
GSM850, GSM900, GSM1800, GSM1900, UMTS850, UMTS1900
So you want to use HTC Gratia or Aria A6380 in Europe and I guess AT&T is selling Aria A6366.
Btw, you can find all 3 of them in the Device Database of this site.
I am not sure where you can verify which version you have. If you figure it out please let me know...

Hey may actually have the Aria sold in Asia, which is compatible with euro HSDPA.
CMage,
my Aria from ATT via Amazon shows Model number "HTC Gratia A6380" from Settings>About Phone>Phone Identity. It was shipped in Aug. Thought this was interesting based on the list of available models.

Interesting indeed. HTC didn't even announce the Gratia until October 2010. So does your Aria have the AT&T logo on it?
I'm thinking about picking one up for review. I'm on T-Mobile and I know the phones come unlocked, but I want to be sure there aren't any hidden surprises or anything like that. If I put in a T-Mobile USA sim card, am I guaranteed to get Edge signal?
Where did you find out that this phone will come unlocked on T-Mobile?

He never said that.
He asked if the unlocked i9100 will at least get edge on tmobile network.
good question..wonder if anybody will get it
I think most of the world uses the same frequencies for UMTS EDGE, so yes... an international Galaxy S II should work on T-mobile with EDGE, though you will have to program all of the tower/apn data into the phone manually to get everything to work
Probably not worth extra cost and effort to get a phone which will always be slow due to frequency mis-match.
It would only work on 2g for T-mobile USA.
I'll enjoy the G2X for now and then switch to the SGS2 when it get's to T-Mobile.

Bump, still wondering if ant T-Mobile users got the phone yet.
I've placed an order with Handtec, but thanks to a long back-and-forth security process I have to wait for next weeks batch of devices (ugh).
I'm assuming 2g will work fine - I can't think of any reason why it wouldn't. I've bought international phones for use on T-mo back in the pre-3g days, which in a way I'm still stuck in. Rural Iowa is not exactly blanketed in 3g...
Off-topic.
http://www.bgr.com/2011/05/05/samsung-galaxy-s-ii-passes-fcc-with-att-3g-bands/
GT-I9020T (Nexus S) - T-Mobile
GT-I9020A (Nexus S) - ATT
If you are to follow the naming convention above, then this new phone that passed the FCC should be for T-Mobile.
GT-I9100T (GS2) - T-Mobile
it will work on 2g but nothing else until the version that supports tmobiles AWS 3g/4g bands os released. im thinking about pulling the trigger anyways

3G/4G will not work as they use 1700/2100 instead of 850/1900

Hi I have a SGS2 on tmobile USA. Here are the issues. I phone is ASIA version rooted.
Tried a few mods didnt like it much.
Big issue is the phone defaults to GSM (2g) and the only other option on the phone is WCDMA. On tmobile it doesnt show edge or HSPA so I can connect for faster speeds.
I went to the tmob store the guy said the firmware needs to be updated but samsung doesnt have anything new.
I am hoping to download stock mod from say europe or canada that enables 4G to see if itll work on tmob. I called tmob they said they cant help as they dont support the phone! i asked for the bands that tmob uses 3G/4G on ( they refused to give it to me)
Tmob came in late in the game for 3g/4g so im not sure if they are on some diff bands that the phone cant catch. although i have not tried inserting an Att sim in it to see if it will get 4g speeds.
if anyone knows of any other options please let me know at this point im paying for 4G speeds on tmob but getting 2G.

Dude, the GS2 doesn't support T-mobile bands. Therefore you'll only get EDGE speed on that phone until you get their Variant or switch to AT&T.

You can never get past 2g on T-Mobile, ever. It's a hardware issue not software, you are stuck with EDGE speeds unless you switch to AT&T.

You can get a cheap medianet plan and get 3g since AT&T will not recognize this as a smartphone, the plan is unlimited too
I have seen many Thread about I9000 trying to convert T959 modem to use the T-mobile network. What i couldn't find is from T959 to I9000 to make it to the international version.
I have the T-Mobile Vibrant T-959 unlocked with ECLAIR. I know that the network band of this phone is 850/900/1800/1900. i found the result according to Samsung website. I know in another post it was said that it is hardware issue but the hardware is 850/900/1800/1900.
I live in the United Arab Emirates and the network band here is 900/1800 similar to the European or Asian Network. but the T-mobile uses 850/1900 so i couldn't get 3G or any kind of internet connection here, unless i find a WiFi connection. I need the 3G connection on the move.
I want to know is there any way to change the the modem band to I9000? so that i can use a custom rom like Darky which is Stable according to many users.
I would never be using the phone on US T-mobile or any Network in the US.
You might think this Question is redundant and has already been answered but i search every where but it comes back empty.
Your feedback would be highly Appreciated!!!!
I don't think you can actually change your phone's bands.
However, an unlocked US T-Mobile Vibrant should be working on 3G. According to Wikipedia, the two 3G networks in UAE (du and Etisalat?) use the 2100MHz band, which should be supported.
Thanks for the reply, i tried everything but nothing worked.
One more question to ask, what will happen if i flash i9000 rom and radio on a T-mobile phone. Or should i just flash it with a T-mobile rom without changing the radio, and if the sim gets locked I will just unlock?
this is the final question to ask.
Don't know if this helps but I use my unlocked vibrant in the uk, so if European bands are the same...it should work.
You can change roms and I would recommend you should but you can't use an i9000 modem.
Do you have a Sim with a data plan?
Can you text or make calls?

Yes i can make a calls and send Text but no internet connection. I just bought data plan for my sim.
So i Should get Vibrant custom rom not the I9000 rom?
And thank you Guys for your replay, I hope this tread will help other confused users on XDA
I would like everyone to know that it is not good thing to change there modem from T959 to i9000 your phone will brick never do it.
I just flashed a new rom from Trigger 3.2 which upgraded to Froyo 2.2 and i put in the settings for the Access Point and it works perfectly.
So if you have any difficulty accessing 3g or HSDPA connection on android 2.1 just upgrade it and it will work.
How did you conclude you're not on 3G? Do you get EDGE or GPRS internet connection?
So i need the 1800 mhz how can i do?
Flash a i9000 modem and see if it works.
Sent from my GT-I9000 using XDA Premium App
There is the possibility to brick the phone?
Hi,
I am currently in taiwan, and I was just wondering if I bought a gs2 here, and unlocked it, would I be able to use Rogers with it? Im scared that after I buy it, that some functions won't work. Im a total nub at this so I tried to search things up, but nothing came up. Please help .
gching
Really depends on the 3G bands it supports as different countries will have different versions of the SGS2. If it supports 3G 850mhz you're good to go.
its in chinese (which i can barely ready ) but it says something like HSPA 21 Mbps, does that represent the 3g or 4g
My phone is from the UK and i'm on fido from Canada. Everything works perfectly fine. I believe Rogers owns Fido too, so I would guess yes. Everything should work just fine.
my friend tells me because im buying it from taiwan, that it is automatically unlocked so i dont need to unlock myself, is that true?
I am using it right now with Rogers. No problem at all.
I just flashed my rogers lumia 920 using navifirm with the .1002 ROM because .1001 was not there. Well, phone is working fine, BUT...this new firmware disables AWS 1700!!! My Wind SIM is only connecting in AWAY mode, and when I insert a Rogers SIM, and select manual network selection, both Wind and Mobilicity have disappeared! Only Fido, Rogers, and Bell are showing!! Radio version and everything else is the same! Does this mean Rogers crippled the firmware?!

Probably something else. Their website list support for AWS band, not unlike AT&T which Nokia did not list any AWS at all. Just a curious, did you have your phone unlocked or still lock? Try to determine if it still using AWS when you put your Wind sim into it by following this
http://forum.xda-developers.com/showthread.php?t=2015907
I doubt it as I am running .1002 and I can see WIND and Mobilicity in the network list. I haven't tried to connect to WIND as I dont have SIM card for them.

Phone is still unlocked..and wind sim is only connecting in Away mode. It's not even connecting to 3g. When performing a manual network scan, it shows three networks, all titled (Wind Away).
I had flashed an AT&T ROM a few days ago for kicks, and reflashed the rogers one. Could flashing the AT&T rom have permanently disabled the radio for AWS?

That maybe the trigger. Sometime flashing another rom over another will leave some files behind.

Try doing a hard reset. I know with the old WM phones the rom cookers would ask you do a hard reset after flashing. Or try flashing again.

Tried all of that. I cannot believe how much AT&T crippled the firmware! Even the radio version, firmware, everything is the same as on my other Lumia 920, the one which I mistakenly flashed an AT&T rom and back to Rogers ROM has lost AWS 1700

AT&T. Rethinking possible ways to screw everyone. Even if you bought your phone somewhere else.
flashing ATT firmware on Rogers Lumia 920 WON'T disable AWS1700. i do have a Rogers Lumia using on T-Mobile/ATT and flashed an ATT ROM and i still get AWS1700 on T-Mobile. i have SG Note2 on TMo and verified that my area only uses AWS1700 on 4G not the refarm 1900. my wife's iphone 5 only gets EDGE on T-mobile when i put my TMo SIM in, so refarm 1900 does not work on my area.
maybe reflash it with Rogers .1001 and then .1002 after.

flashing ATT firmware on Rogers Lumia 920 WON'T disable AWS1700. i do have a Rogers Lumia using on T-Mobile/ATT and flashed an ATT ROM and i still get AWS1700 on T-Mobile. i have SG Note2 on TMo and verified that my area only uses AWS1700 on 4G not the refarm 1900. my wife's iphone 5 only gets EDGE on T-mobile when i put my TMo SIM in, so refarm 1900 does not work on my area.

Where can I find Rogers .1001? I have it on my other phone, but cannot find it on navifirm. My other Lumia is just fine, but this one screwed up after the flash, and I don't see any AWS 1700 network at all.
I'll just copy what I wrote on WPCentral over here:
"I have a Dev 920 which worked on AWS 1700. Then it was flashed to AT&T which disabled the AWS 1700. Then it was flashed to Rogers which you'd think would bring back the AWS 1700 but it did not. I cannot flash it back to Dev firmware because Nokia doesn't have it available.
It seems AT&T firmware cripples the AWS 1700 permanently somehow. And the Dev phones are RM-820 which are North American phones."
Although I also flashed to .1002 since that's what's in the Nokia database. Someone find me the .1001 Rogers and I'll test it out.
I have similar experience on this. When I flashed Lumia 710 (US TMO version) after sending a wrong update (yes, I've bricked it by sending wrong firmware), I've recovered it by uploading Rogers' image. That worked fine. I then revered it back to TMO image. The device, 710, works great and everything. It even has TMO boot screen and applications. However, my setting/about screen still says "Carrier: Rogers CA SW variant ID226 v.01".
Perhaps there's something that stays behind even after FW flash.
To enable AWS
Try flashing RM-821 VAR EURO1 DEVELOPER firmware on your device. I was skeptical flashing RM-821 firmware on RM-820 but it enabled AWS. My developer device is back to running on HSPA on T Mobile ! (http://forum.xda-developers.com/showthread.php?t=2097815&page=4)
