Lol waste 5 credits for unlock phone from T-Mobile use App Block =)) funny

suchywilk · 07-04-2017, 07:57

Did you try to flash T-Mobile phone with At&t firmware ? At&t firmware will ask to put network unlock pin and AT&T are SM-G955u also.

suchywilk · 07-04-2017, 08:00

Sorry your Mobile is SM-G950 not SM-G955.

Linkz · 07-04-2017, 08:32

Even if you flash G955USQU1AQD9_G955UOYN1AQD9_USC the CSC is still TMB. You probably need to try after changing the CSC to ATT and then try to unlock.

USflash · 07-05-2017, 01:41

Will this solution work on G935T?
Thanks

mithun1997 · 07-15-2017, 04:16

flash factory binary. then it will ask for unlock code.
Now it asking for unlock code. But i don't have unlock code.
I don't have access to post download link
type "ENG Boot + Root" in google. and get factory binary download link in xda.

jinu_j · 07-15-2017, 13:55

Has anybody tried this? It would be remarkable if it works.

ATT ATT

XAA Unlocked US
SPR Sprint

Don't entirely know which ones these are:
GCF World Wide
ACG Some Mid West Carriers
LRA A bunch, cant figure it out

ACG is C-Spire a Sprint type service
LRA is LTE in Rural America a Verizon type service
GCF is some unknown roaming service

I think it would be better to do the carrier change first, and only then read the unlock code. Because if you read the code first on the original carrier, then the code may not work properly on the changed carrier.
So try to change to ATT carrier first, read the code, and enter code.
Report back please.
