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?

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 !!
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
I'm not responsible if this damages your phone, attempt at your own risk.
Hi everyone, I have stumbled upon what appears to be a working unlock solution for the G flex 2 (LS996). This is essentially a similar method of unlocking the g3, but with my unlocked by sprint node.db files. Currently MMS and Calling are not working for me on ATT, but data (LTE) and texting works. I beleive I know why calling is not working, as well as MMS, but I am not sure how to fix it, I am new to unlocking using root. Anyways, on to the guide.
First you will need to root your G Flex 2
You will also need Root Browser
Now after you have rooted download the files attached to this post
Next transfer the files to your phone if you did not download on your flex2
*Back up your node.db and node.db-library by adding .bak to the end in /carrier/apps
Once the files you downloaded are on your phone extract them to /carrier/apps
Now restart your phone with your non sprint sim card, or sprint if you are unlocking for future use
When the phone boots you should see that it is recognized, but the carrier still identifies as sprint
Go into settings, more, set mode to global, then go to apn settings and add in your apn
Now you should have full sms and data
This is as far as I have got at the moment, but I am working on calling and mms on at&t, it did appear to be working on Verizon though
Now to where I need some help:
First is calling. I think I have identified the 2 things that may be causing the problems. First is call barring, when I opened up a hidden phone menu it said that incoming, outgoing, etc calls were locked. When I try to enter that submenu to unlock them it says something about the sim or crashes. Next is hd calling. When I dial a number there is a hd symbol next to dialing, I don't know what that is, but if it is sending the call over data I am assuming that there is some type of problem with it sending it to a sprint server or something. If someone can help me figure this out I will be very thankful.
My next problem is MMS, on at&T. Whenever I try to send or download one it does not work. I might just have messed up my apn a few times but I doubt it. The MMS settings in hidden menus show up with sprint settings, and I have tried changing them but they just revert. Could anyone help me out?
PS Sorry about adding two files the first one did not show up when I posted and now I don't know how to remove
I am getting hands free activation now and then please help.Tried everything below.

Try this..
with root explorer : Go to system/app or /system/priv-app folder.
Locate Sprintsyncml. Apk
Rename it to Sprintsyncml. Bak
or
Search for OmaDmclient.apk, then click and hold the file till it popups a secondary menu, in secondary menu select RENAME.
Rename OmaDmclient.apk to OmaDmclient.apk.bak and press ok.
or
LGstartupwizard.apk... Which is located at
/system/priv-app
try this options it should work..it will disable the prompt
Thanks only found LGstartupwizard.apk but it is still popping up after rename..Please help

Yes that's true. Take care about permissions setup, use root explorer for that purpose. In three countries I use this phone LTE works mostly in bands 4, I also enabled that band using a guide I found here.

I had the phone unlocked by sprint and can still not hook on to AT&T. What are you offering?
5.1.1 can unlock gsm sim too? Thank You
Changed my build.prof and got calling working flawless, just cant seem to be able to change apn settings.
ro.carrier=spr
ro.build.target_operator=spr
With this, you can also changed the spr to tmo if you want.
Anyone know how to make it so I can change apns?

When in the build.prof editor in Root Toolkit Lite, I simply changed it from "SPR" to "spr".
##data# isn't helping because I dont have the msl/spl. Everytime I go to change the APNs it wont allow me add one in. I can edit files if needed, I just need to be able to edit it haha

@carlosirai, others,
can you help me a bit, as your post intrigued me as follows :
i bought this phone - rooted and unlocked as per method above by ebay seller for international usage.
currently, the phone is technically domestic unlocked and rooted on ZV6. this results in no OTA and node files for SPRINT modified!
as an internationsl user, who will not be using US Domestic providers or Sprint, can i unroot on ZV6? then upgrade to ZV9 then root as/if required and use with an international provider? this usage will be on 3G & LTE ( Bands can be enabled as required, post root )?
thanks in advance!
any help you

Yes to all you said.
You need to flash stock zv6 system image and ota update to zv9, then root with zv9 rooted system image and do the "fixes"...
Excuse me, I was bought ss note 5 N920v from Aliexpress to Thailand and already unlocked but it has android 6.0. I found 7.0 rom (https://forum.xda-developers.com/verizon-galaxy-note5/general/sm-n920v-nougat-odin-firmware-t3592899) then I flash it via odin . When finished reboot. It appeared "sim card is not from verizon wireless " and I can't use 4G mobile internet so I think it look like re-lock network again. This case can I use verizon unlock service on ebay? or you have the better way for free? Thank you.
You dont need to relock it.
Note 5 VZW is UNLOCKED!!!
Ignore the message "sim card is not from verizon wireless"
You need to setup you carrier APN settings to use 4g connection
but the signal is very weak and the previous version that buyer flashed 6.0 but my signal is full and didn't has verizon logo.
