Baseband with the Metro ROM is G920T1UVU1AOCH, but the problem is, I flashed both of the S6's I have here to the Metro ROM to unlock them so I have no idea what the original baseband was lol I hope you do!
Any luck on the S6 Edge unlock? I scour the internet everyday for developments but I havent seen anything I feel like this S6 Edge I have is either going to sit here forever or Ill have to sell it as a blacklisted phone because its financed and I KNOW its going to get blocked.

the fact that baseband has a G920T1 means that it did changed the radio , while every damn firmware i tried never change the baseband ., is good to know though ... and if you have an S6 Edge try this before selling it .. ask to borrow someone's tmobile sim card and try to at least do a temporary unlock if that doesn't work then download the app VyprVPN select germany (i did) with the tmobile sim still in and try temporary unlock again,,, doing this at least it bought a month's use of my phone , maybe a solution will come up later on.

So youre saying that when you flash the Metro ROM to it, its not changing your baseband? I used the one posted by UnlockBase. Were you able to successfully unlock yours?
And yeah, Ive tried the TEMP and PERM unlock on the S6 Edge. I put my TMobile dealer SIM in it hoping that would help as its a free $80 monthly demo line I get for selling TMobile service. I would gladly try that method, but since we sell these phones, a TEMP unlock wont help me I need a permanent solution so once I sell it, Ill know the customer wont have any issues down the road. I have both of the S6's up for sale now that they are unlocked, but I have always wondered if Samsung REGION LOCKS these phones. Ive tested my personal ATT line in it, and it works great, but alot of my customers on eBay export these phones overseas, so Im hoping these new Samsungs arent region locked :/

when you try to flash any firmware with odin it ends on FAIL.. you can flash rom with twrp but baseband remains the same ,, so i dont know if the unlock app from tmobile is tied in the bootloader or radio or something else ... so far i'll just enjoy the 30days left and see what happens after that ... cause after it accepted my att sim card a message will appear reminding me the unlock was to end on Jul01 and if i wanna to do permanent unlock, so i flash a firmware from a canada version G925W so the reminder went away but i dont know if that means that in 30 days i'll be locked again

I gotcha. I did something similar. I flashed the international ROM on the S6 EDGE via TWRP and it told me the code is incorrect. I know the code is correct because if I ever it in with no SIM and the #7465625*638*# and put the code in it says successfull. This is SOOOOOO frustrating. The lock has to do with the radio or the bootloader/baseband.

I am interested to see if that works which it may as the app is not there to retrigger the lock. You never know.
I currently have metro pcs and I bout an unlocked Samsung galaxy s6. My original Sim is too big so I have to go to metro to get a new one but the phone is not reading the new sim in order for them to program it. How do I fix this or get around this? Should I not let metro try to activate the phone?

Confused if phone is Sim locked or not.

I bougth a second hand s6 edge t-mobile version 64 gb. No issues with the smartphone until i checked for an update.It said the devise have been modified and connect......
I searched and searched about this and when i went to system status,it said custom. I thougth the devise migth have a custom rom but for no reason i openned the unlock device app for t-mobile and it showed my devise was locked yet i had no carrier problems. It even said permenant or temporary unlock . Both of them failed.
Im thinking of taking this phone back to the seller but i want to be sure if its actually locked or some other issue. I think a custom rom was installed on this devise to unlock it before i purchased it. Any ways to know if phone is locked or not?

LG G5 Nougat 7.0 update issue

I have a Sprint LG G5 unlocked phone. Was using another sim card from another company without a problem in Singapore while traveling till I got an android update. I did not know there was an asian version. Now my phone is locked again and Sprint says it is showing unlocked on their end but that there is nothing they can do until I get back to the US. They said the asian update does not recognize the unlock. Any thing I can do or do I have to wait till I get back to US to do UICC unlock? Any help would be greatly appreciated.

[Q]Help SIM unlocking Tmobile SGH-T999 for use in South America!

Hi all, I've been reading tons of threads and I am still having some difficulties with this phone. I am not in the US, I got this phone from a coworker that was going to throw it away and brought it with me to south america to give it to my friends mom who has no money, its and old phone but the one she has is even crappier ,I thought I would be able to just pop the SIM and get it going but nope.
If anyone could point me in the right direction I would really appreciate it, I have a few more days before I go back home and I would love to be able to leave this working for her.
Let me put you up to speed:
-Phone is running Android 4.3
-Phone was rooted using Odin, has SU and CWM
-Followed thread here to SIm unlock: https://forum.xda-developers.com/showthread.php?t=2023709 but #4 option is not present on 4.3
-I tried downgrading to 4.1.2 custom root666 to see if I could get #4 but to no avail since you cannot from this 4.3 version
-About to follow this thread :https://forum.xda-developers.com/showpost.php?p=48012926&postcount=8
but not sure if correct for what I want to do.
No more ideas, please help!
The phone can only be unlocked used an unlock code. Try contacting T-Mobile for a free unlock code or buy a code from eBay.
i'm with the same problem. i bought an sgh-i747 and after two months it bricked, so i replace the logical card (i don't remember how to say it in English, lol.) and boom!!! now i have a t999 and it doesn't work with movistar. (i'm from Venezuela)
but well, i've been reading posts about unlocking the phone and every one of them only works in JB 4.1.x. i don't know if i could unlock it by the downgrade process and i'm scared of getting the phone bricked again.

---Help Needed--- AT&T LG G4 Bootloader unlocking with AntiRollback v3

Hey everyone! About a year ago I bought an AT&T LG G4 of of ebay with the intent of using it as a daily-driver phone. The seller listed it as Unlocked, and only mentioned the model number at the bottom of the page. I didn't look at that first, so I ended up with an AT&T G4.
It's unlocked, so I can use any sim with it, but the amount of AT&T bloatware on it is INSANE. So I used it as a primary phone for a few months, but than ended up shelving it, and using it a secondary, playarround phone.
And now as I'm not using it, I'm looking for a methood to unlock the bootloader and get rid of the AT&T bloatware. So today I looked arround and found out that the AT&T G4 was indeed unlockable but, you need to have AntiRollback V2 or lower. But my phone has AntiRollback V3. Is there any methood you can unlock an AT&T G4 with AntiRollback V3?
If I lose the simcard funcionality it doesn't matter. I just want to get rid of the bloatware, and update to a never version of android.
Any help would be appriciated.
