Pre-requisites:
a) Rooted
b) CWM Installed
c) Sim Unlock Code
I could not find a straight forward way to get the ATT SGH-I727 Unlocked and working on T-mobile so I thought I'd make this short list of instructions for those going through the same trouble.
The first thing I had to do was unlock the phone. I contacted a local company that charged $35. Free options failed. Expect to pay. There were mentions of calling ATT for the unlock code which I did, however, the CSR looked up the IMEI and determined that the unlock code was not YET available. From what I gathered, because the original phone owner was still under the two year agreement, this unlock was on hold until that time period was up. Those that bought their phone outright without a contract are provided their code with a call to customer service.
With the phone unlocked, I still couldn't get the phone to connect to a T-mobile signal. With a tmob sim, either a no-signal icon appeared or the phone simply showed full ATT bars but wouldn't allow T-mobile use in options. Also, *#simunlock# would generate a com.android error.
Finally, the following formula allowed for an unlocked phone picking up T-mobile signal:
1. Install the STOCK ICS UCLF6 4.0.4 - UNTOUCHED - rom following the instructions on that page impeccably.
2. Install Busybox (may not be necessary)
3. Install UCLF6 modified boot Kernel
4. Install T-mobile compatible radio - Blaze_4G_LB7_ICS_Radio_MOD worked for me
Boot it and see if you have a signal. You may need to go to options and manually choose T-mobile.
After that, I was able to install a different ROM. I chose SKY-ICS 4.2F6-2.6.1
With any new rom, you will still need to flash a tmob supported radio.
My s.o. will be using this phone, so I won't be messing with other roms, unfortunately. Let me know if you have a fast and stable configuration.
I hope this helps.
Actually as the radio is deeper than the firmware we flash normally you should only need to flash a tmo radio once unless a rom has radio built in most all roms do not

Does it make a difference whether I install the stock ics and kernel you provided? All I did is update the phone to ics via kies, install a recovery, flash superuser, then installed the blaze 4g radio. Would it make a difference between doing what you said and what I did?

Any luck with that? I'm trying to get mine to work but had to flash a t989 rom on it instead

It works, but its very crappy, sometimes connects, sometimes doesn't, even followed this post's instructions, still has crappy connection
For those who have T mobile fine on the Skyrocket , how much DL and UP speeds are you getting (and compaired to true T mobile phones data speeds) ? I heard some say they never get more than ~1 or 2 mbps which sucks TBH
Heard this is the hot T-Mobile skyrocket radio.

Are you trying to get Call/Text connection or 4G HSPA+ Connect?
Works on WIND too!
I spend a while trying to get this phone working on Wind (Canada's 1700 AWS carrier, similar to Mobilicity / TMo). I've finally succeeded by doing the following.
1: Install latest ICS STOCK
2: Use CWS to flash AT&T UCLF6
I have not been able to get nearfield working with this modem, but it's working great other than that (albeit somewhat slow UL/DL speeds, but that's likely a more wind's crappy network than the phone). Let me know if anyone has any ideas regarding the Nearfield issue.
Just wanted to share. I have been made so freaking happy by the fact that this worked
I bought my SR for full price (549.99) months ago and stupid att also saying my unlock code is not available yet !!
Hi,
I just migrated my VZW phone to AT&T, and was having issues with texting. Working with the ATT rep, figured out that "Message Center Number" option was disabled or not available on the VZW install. I don't have hidden menu enabled, running 4.3, so nothing with *# will work. So I thought before, I go ahead and do a CM10.2 install and try it out. I wanted to see if I can install stock 4.3 (or older) ROM on my VZW phone. The GS3 phones offered by phone vendors almost identical.
Thanks for your help in advance.
No, you cannot install an AT&T rom on your VZW phone. There are hardware differences between the models. Flashing an AT&T ROM on your VZW phone would result in a hard brick.
Hello all! I believe what I am trying to do is possible, but I am having trouble figuring out exactly where I should start.
I just bought a Verizon Samsung Galaxy S3 model SCH-I535 with a clear ESN on Ebay and am hoping to get it working with my Straight Talk service. It is running 4.0.4. Will I need to update? Is rooting required? I have tried updating manually but it failed. Is there a universal android 4.1.2 (or other) firmware file I need or do I need a file specifically for my phone?
The phone came with a Verizon sim card, and the phone I am currently using on ST does not have a sim card, so I am assuming that I will need to buy an AT&T sim card, right? Then I can activate that sim onto my ST account? Then the rest is a matter of the proper settings?
Thank you all for your expertise.
So here's my situation.
I have a Verizon Galaxy S3 I535 I have been using on Verizon's network for about 2 years. I am switching to a local carrier that shares towers with Verizon. I am trying to use my I535 on the local carrier. I got a SIM card from the local carrier, put that in my phone and I can make calls and receive text messages but not send them.
In order to attempt to resolve this issue I planned to Wipe the phone and put a custom ROM on to ensure that none of Verizon's software or settings is preventing the texting from working. Problem is I am running KitKat version 4.4.2 that has Verizon's bootloader lock.
I got the phone rooted via Towelroot and CW ROM Manager installed. (rebooted into recovery mode got the "Verizon found unauthorized software yada yada." Got the phone back to a "normal" state with 4.4.2 rooted.)
My questions are:
1. Do you think putting a custom ROM on the phone will resolve my ability to send text messages?
2. Texting works on these same towers using Verizon. Can the backend hardware at Verizon allow the phone to work properly, but not the local carrier? (I have verified Local carrier Galaxy S3 is a different model number)
3. Is it possible to overwrite the bootloader/rom via ODIN
4. Is it possible to brick a phone so bad that you cant even reload the default OS via ODIN

1. Sounds to me like it's not sim unlocked.
2. A custom rom may or may not work in this case, if your on the 4.4.2 OTA your limited to two current roms other than stock using safestrap, disregard the custom rom part
3. The bootloader is locked so once again your limited
4. And yes you could very well hard brick the phone while not doing something correctly

Thanks for the Reply
1. I called Verizon when I was planning to switch. They told me my phone is unlocked to use on any carrier. They also gave me the code '000000' if it isn't unlocked. I never received an error message or a place to put an unlock code when using the new SIM. Do you have a link I can reference to ensure that it is unlocked? I have done several searches and haven't found anything that works. There are several that say to type in secret code *#XXXX# but my phone just attempts to make a call and says "not a valid number". Any help is appreciated.
2. Are you saying that i would be able to put a custom ROM on like Jelly 'Beans' or Clean ROM? If yes, can you post a link for that as well? I have done some extensive searching and most of the results applied to phones that were pre 4.4.x release.

I honestly know nothing about sim unlocking. If it's on 4.3 or 4.4 and it took the OTA your very very limited to what roms you can flash.

Hello, just upgraded from a Galaxy S4 on T-Mobile to an unlocked Verizon HTC One M8 handset. Popped in the sim, I can send and receive text, data on HSPA/3G mode but not one LTE or Global mode (anyone know why this is? I'd like to be able to use t-mobiles LTE and not just HSPA/3G), get the usual "sim unknown source" stuff. I am wanting to flash Skydragon.
My question, is there anything special I need to do before/after I flash these, since I'm using a different network than what the handset was originally supposed to be on? Maybe I need to flash different radio? This is my first time using an unlocked phone, previously all my phones with custom ROMs were on the same network as the handset variant.
Otherwise, would I just update to the latest 5.0.1 OTA update from Verizon, root/unlock bootloader, install TWRP, then flash Skydragon, and I'm all good?
Edit: Well, further reading seems to indicate to me that it turns out verizon M8 devices already updated to 5.0.x are still not able to be rooted at this time?
Thanks for the help
