[Q] Extremely hard Unlock SIM GS2 LTE (Skyrocket)

Hello, I recently bought a Samsung S2 Galaxy (LTE skyrocket - AT & T) of California, however, I live in Brazil and the phone came locked only for AT & T.
Here in Brazil we have a law requiring phone companies like AT & T Rogeres, etc.. Here they are Live, Tim, of course, Hi, just that they do not unlock phones abroad. I tried to contact AT & T however only support residents in the U.S., Brazilian contacted samsung and I answered that are not responsible for the distribution of this model (LTE) and that could not support.
I tried to unlock it through the cellunlocker, but I had no success in negotiation.
Researched and tested and there is no functional application for the release version LTE.
So I come to you guys asking for God's sake, who could unlock the LTE free. and if possible as it did, through that program, what a miracle it did, very grateful.

I read, but do not think it's about the frequency, the real situation is to unlock the sim lock, and even with those mods, I believe that the cel is already unlocked them

yes i'm in the same boat, except mine is working. i have root and what not but i just want a clean rom like phantom blazer. but when i installed it everything worked freaking awesome....except no cell signal since its geared for sprint only, i wonder how hard it would be to adjust it to US Cellular.

Here is the rar file from my dropbox for CWM backup of my phone. (The file is being Uploaded)
https://www.dropbox.com/sh/ucd5lxmup5ibnxk/QxnDuVDtE8
There is one more way
Just odin the Verizon system rooted unlocked image. tar (1500 mb) Its rooted system image of Verizon. It works fine for me. All Verizon custom ROMs work too. Stock ROMs fail at the modem stage. Once the boot loaders are unlocked they will load too.The baseband remains of US Cellular.

MD5 file Question
There is a Kies updated for USCC phone. Kies downloaded a file and placed it in the Binary folder.
Named "VZW_HOME_R530UVXALG4_R530UUSCALG4_961795_REV00_user_low_ship.tar.MD5" can this be flashed using ODIN to create a stock phone. Sorry new to flashing

Can SCH-R530 be used on GSM network?
Hello,
Can the US Cellular SCH-R530 be used on GSM network? I read about the Verizon SCH-I535 being turned into a world phone. The AT&T rom can be flashed to the SCH-I535 and everything works. I think the only thing that cannot be flashed is the ATT modem into the verizon S3.
So can something like this be done to the SCH-R530 phone?
If anyone is willing to try or has any input, please let us know.! Thank you..

Are you sure the Verizon ROM will work smoothly in Samsung S3 R530 US Cellular and not brick the phone?
Is the Verizon S3 I535 and USCC S3 R530 have the same hardware?
thanks,

If you haven't found help yet, this should fix you ups. All you have to do is install CWM via Odin and then flash one of these!

I believe this is a global phone that can do either GSM or CDMA. Either you can get Verizon to unlock the SIM for you, or you can unlock the SIM using the same method as the Galaxy S2/3. Just search youtube for instructions, BUT it will only work if you are on version 4.0.4. It will NOT work on 4.1.2.

Which international variant of Note Edge will work with AT&T LTE/4G

Hi, I would like to buy an unlocked (carrier/region) Note Edge. Can some one suggest the variant I should buy that will work with AT&T 4g/LTE bands in USA.
SM-N915F
SM-N915G
SM-N915T
Etc?

I don't think that is possible, as each countries have different band. That's why most international/factory unlocked phones don't have 4g/Lte capability. 3g and some lte is the most you are going to get with an international SM-N915F
Best bet would be to buy out an Att phone, and request them to unlock it so you have the 4g/Lte in the states.
I believe its a 30day period or so when the account is open before they give you the code. I know t-mobile policy is 3-4 weeks.

go with the 915T (tmobile)
tmobile edge is the only one that has an unlocked bootloader (you can flash any rom, etc that is made for the EDGE)
the ATT, Verison, Sprint, etc are bootloader locked, and you cant unlock them as far as i know
Tmobile one, once its unlocked, thats it,, a world of possibilities in your hands.

Thanks. But why not SM-N915F the european or SM-N915G Asian version? are you saying those are also boot loader locked?

I am an att customer currently in Kuwait and I purchased the 915F because the LTE does crossover to them. I looked at the LTE bands and 2 out of 3 of them are the same. You just need to ensure you put the correct apn in.
I hope this helps.

The Note edge 915G will work with ATT LTE/4G
I have that model on Tmobile 4G LTE and it works fine. Since the update they took out the Lte icon and replaced it with 4G. But when you check the status menu it says LTE connection Type.

Is there a root for the Verizon note edge? If there isnt ...could I use a different model number with Verizon,and if so which one could I use. I would like to be able to root and bootloader unlock. Thanks

The only root for Verizon Note Edge is with the developer edition. And no you can not use any other Note Edge variant on Verizon.

To get the AT&T lollipop update on a tmobile phone you will need to use Kies or Odin 3 to flash it as it won't recognize the tmobile Sim when attempting to look up AT&T servers for the update.
