If no one hasnt read, US Cellular is finally get a variant to this phone, except they are calling it just Galaxy S2. Really contemplating on getting this phone, I just wanted to ask anyone who is knoweldgeable if I get this phone, can I root it and load CWM and stuff on it from your ROMS? or would I have to wait until one comes out specifically for my phone even though they are both CDMA and the specs are the same from what i see.

You will probably have to wait for someone else does that ans then you can do it.

Its hard to say man without seeing the phone. There could be very minor differences that would not let a Rom be able to flash for that phone. It would be very easy for someone to port the Roms over especially since they are both CDMA

I would like to know the answer to that too, I just picked mine up. Android ver: 2.3.6,baseband S:R760.01 K.FB14
There is someone selling a barely used Evo4G for around $100 and I'd like to get it. I'm just concerned with rooting and custom Roms.
1.) How easy is it to root and install a custom rom?
2.) What is this GSM / CDMA thing? I'm a super newb so I'm not really sure what those are. How do I check if the network I'm using is GSM or CDMA?
3.) The seller says she got it from Dubai. Would there be different hardware versions of the device like some of the other phones with regional differences?
4.) What should I watch out for when installing custom ROMs? Like I know some roms for sprint wont work for verizon or something...

1. It's pretty easy to root but if your on the latest update which is 2.3.5 you have to use HTCdev.com or you can downgrade to to use another exploit like unrevoked it revolutionary.
2. GSM are phones that use SIM cards. CDMA are phones that do not use a SIM card.
3. Nope the evo4g was only available in the US. There are multiple hardware versions like 004. Only way it would be available there is if it was exported there and flashed to another carrier that met the requirements
4. Roms are device specific. You have to flash roms meant for your device. If you try and flash a rom from another phone you could brick your phone. There are some roms that are only for metro PCS users and boost mobile. Just don't flash those and you should be fine

+100 on this . Ciudado.
There are no GSM evos. And I have my doubts there are cdma networks in Dubai (or whatever middle eastern place the OP said, I forget the OP).
your cant put a rom for a Verizon phone on an Evo, unless somebody ports it for Evo.
Good luck. You're wise to ask your questions here, that was a good call

Yeah I'll check it out first and try to play with it before buying it but the phone part of it isnt really a big deal. I only have one sim card and I have my optimus one for that. I just wanted to check if it really is an Evo 4G.
I think that the main reason it is dirt cheap is that the owner doesnt know how about it being CDMA only and it is unusable for her here... I'll treat it as a a an entertainment device
The picture of the phone shows a Sprint logo on the back. So I will be flashing only Sprint specific roms right?

Every rom in the evo4g development section are Sprint specific except a few. You can only flash roms for your device not others. The evo4g is a Sprint phone every Evo4g has a Sprint logo even if its not on Sprint

Alright awesome. I'll probably put a custom rom on it right away. I'll check the phone out tomorrow so you guys will be seeing a lot of me
Would have wanted to try out a Sense rom but I've read that it's not compatible with bluetooth gaming controllers (wii remote or 6 axis controller) soI'll be looking for CM or AOSP roms.
I was wondering since both the AT&T and Tmobile phones are the same I could possibly flash a stock firmware from AT&T on to my T-mobile SGS III and then use an AT&T sim? I'm trying to use an AT&T sim card. Thought this might be an alternative to unlocking the phone. thanks.
I doubt that it would work

Just because you flash an att rom doesn't mean its gonna unlock the phone to use it on a different carrier. If you try that it will brick or crash. DON'T DO IT! Seriously, if you want to use it for another carrier you can request a subsidy unlock from Tmobile if you have an account in good standing every 90 days. If you bought it threw a third party try another method to get the device unlocked. Or if you bought it right out full price from Tmobile they can process the subsidy unlock request as well. Once you have your unlock code it should come with instructions or if not you can go to Tmobile.com support section for your phone the Samsung T999.

I'm just curious why would it brick the phone? Both of these phones are the SAME hardware wise. Even under the IMEI sticker of my tmobile s3 it says i747..
Radios are different, kernel I believe is slightly different. Just not a good idea unless a dev specifically says its safe.
It also wont help with the unlock. Thats not ROM dependent.
Also, the phones are NOT the same. I don't know why some seem to think they must be the same. What are they basing this on? They are very similar yes, and perhaps the ROM from AT&T will work. I don't know. However, sometimes very similar phones may have some very important differences, like a kernel, radio, or one or more partition/s that may be offset by one perhaps because of some aforementioned reason. Or any combination of those. Don't assume the phones are identical because the Internet says so. If you are confident that the phones are in fact identical, then by all means, flash away. Just let us know how it turns out. It may work.
Do a "getprop" in terminal and you may note some very important differences in there, besides the device name/model, etc. Has anyone seen the ril.modem.board or crypto values from an AT&T SGSIII?
If the mount points are different, which they probably are, you copuld end uup with a very expensive paper weight unless you know how to make the needed changes to the updater-script, which you would have to hack to even flash the rom in the forst place because the ro.device props will be different.
Unlocking a phone has nothing to do with the ROM, most phones give you 10 chances to enter a correct unlock code until the phone it carrier locked with whatever carrier the phone is for.
The unlocking of the phone is usually hard flashed and if you exhaust all attempts, you have to send it in to get reflashed from the carrier.
T-Mobile will generally offer you a free unlock code after 60-90 days of a phone purchase, but that does not mean you can flash ATT on T-Mobile and vice versa.
They are on different bands and have different setups, if they were the same they would just have one phone for both carriers.
OP should try it for the lulz. Phones are SAME! XD
Chances are a repartitions flash in Odin would fix it, but i'm jot sure about that. It's just a bad idea.

I currently have a Galaxy S3, running rooted stock ICS for Tmobile - and I would like to switch over to ATT and keep the same phone, just flash the ATT JB stock firmware onto it (or a custom ROM), and whatever other flashes may be needed to make it work, or something along those lines. Is this even possible?
The only reason I would think it could work is that they are both GSM phones so the tech should essentially be the same right? And since it's rooted, switching the SIM shouldn't be an issue either, as I have done so when I am travelling.
Or are there other major diffs between the 2 s3's that I am missing which make this an impossible.
I have a friend who is looking to buy a new S3 from ATT, and I would just as soon sell him mine with their stock stuff on there if they are basically the same.
Many thanks in advance to any who can help shed light on this.
U have complete wrong idea brother. You cant just flash att s 3 rom on tmobile s 3.
Find some att based rom for tmobile s3 . i think we have some.
Its almost same hardware but not same network antenna. So you cant run att 4g on it.
Simply dont flash att rom on it unless its says for tmobile.

I always thought that Tmo (i was actually told this by tech support once) shares antennas/repeaters with ATT... so I guess they are just piping the 4G through a diff frequency or something, and the antenna isn't tuned to pick it up. damn.
are there any carriers it WILL work with?

The T999 supports at&t's 3G, just not their LTE (T999 doesn't support LTE period).
What was being told to you is don't flash an at&t baseband (radio), recovery, or full ROM to the phone or you risk a brick. Any of the ROMs marked *AROMA* have multi-carrier compatibility, you just choose the underlying device.

Sorry to say, but you are forgetting something, a stock rooted Tmobile Galaxy S3
is not compatible with the AT&T services as well as any of the AT&T roms.
You would need to UNLOCK the phone first before doing anything else.
Good Luck!

pardon my ignorance, but what is the diff between unlocking and rooting, and how can I go about doing it? Also, and this is an aside, the only way that i can find to change the IMEI of a T999 is by using an external box - there is no software-only method of doing this yet, correct?

To put it into simple terms,
Rooting a phone allows YOU to make changes to the phone which includes flashing roms as well as
allowing apps which require root access to work on your phone which are available at the play store.
But rooting has nothing to do with AT&T or any other carriers.
Unlocking a phone allows the phone to communicate with different carriers like AT&T and others.
Your phone does not need to be rooted to work with different carriers, it only needs to be Unlocked.
Also once the phone is unlocked you would need a AT&T Sim card for it to work.
Even an Unlocked Galaxy S3 will not work on AT&T unless you have a AT&T sim card.
There is absolutely no reason to change IMEI.

This is what you need, a SIM Unlock - and it happens to be rather easy on the S3.
http://forum.xda-developers.com/showthread.php?t=2023709 :good:
they are right. you need to unlock your phone. if you go into a store or call customer care they should be able to help you out with unlocking it. i used to work for tmobile and i remember unlocking a few peoples phones.
Hi guys,
this may not be the proper forum for this if it is not i apologize.
I have have the cricket galaxy S3 which I payed retail for a few months ago, I am moving to a area where they do not cover, I would like to bring my s3 over to tmobile but im running into a strange issue.
The phone is set to cdma mode in the the engineering menus i can switch it over to gsm and it has the frequencies that tmobile uses but i can not get it to see anyone else's sim card other then crickets, its not an unlock problem, it just says please insert sim with anyone else's, they do something weird they are cdma but have a sim card and the phone will not work without it. I tried installing a rom with the tmobile baseband as an experiment thinking well it may be that, but it didn't work.
I am having a hard time believing there is not a way to get this done so I am turning to the most informed android community I know of for advice, Dose anyone have any thoughts on how to accomplish this?
Please not I am not scared to brick this phone because if I cant get it switched over its a $500.00 paperweight to me anyway it has a cracked glass so I wouldn't be able to sell it anyway.
What model is it? I think cricket is closely related to sprint or verizon. And as far as I know no ones been able to use those models on the tmob or att networks with any success. Just because the option is in the engineering menus does not mean the phone is capable. It was just easier than creating separate apps for every model s3.
Now that T-Mobile has lte in some areas this may have changed a little, but in the past I know cdma phones were not compatible with T-Mobiles gsm network. So there may be a way IF lte is in your market, but I still wouldnt get my hopes up much.

it is identical to the verizon one, model is like 530 I think and the verizon is 535 (dont have in in front of me), but ive seen on youtube someone get the verizon s3 to work on gsm but hitting a couple settings, hence my frustration.

See I looked at that but I couldnt get it to work with my phone, the part that is hanging me up is it refuses to see the gsm sim card, though outwardly they look identical to the lte card that is in my phone im thinking it has to do with the encoding on them.
i have been trying to Odin flash the stock vzw firmware to it, since the hardware is identical, but i cant get past the qualcomm secure boot check

I wouldn't try that again. Way too risky. Odin won't flash an official firmware to a different model device. But if you get it to it would be more likely to brick your phone than not. I know they're practically identical, but any difference in bootloaders could cause it.

And I know you said you're not worried about bricking it, but even with cracked glass you can still sell it, probably for a good bit more than you think.
And you did imply you are unlocked. Are you though, for sure?

well here is the thing, about the unlocked bit I am not sure, but it dose not prompt me for an unlock code, it simply just dose not see any other sim thats put in it, it just says No Sim. I gave up on flashing it with odin, I remembered the rom I was running had options for all major us carriers in it and cricket so i played around with that re-flashing the rom to it try a few things and well that didn't work either.
Well if you don't get it unlocked its probably not going to work with any other carriers network.

That thread may help. It's for gsm phones so I don't know if it'll do you any good, but it's worth a shot!
The Rom itself will have little to do with getting it working on another network. The main items that you probably need to worry about are unlocking and that SIM card.
The sim is tmob right? Does it work fine in other T-Mobile phones?
If you really do think.it's the Rom you may be able to flash a stock based Rom from the T999. Get verification first though as it's probably not like att where we can just flash theirs and it just works! You'd most likely need it ported.
