I have a question...I have flashed Optus froyo by patching the Kies...Does it lock my phone to Optus...Mine is unlocked phone but I am confused on this point after flashing to Optus firmware...I haven't got a chance to test with other SIM...I was on ZSJF5 eclairs
nope. It only installs optus branding, links and apps which can be removed via titanium backup with root. Optus Galaxies have never been sim locked. As far as I know only prepaid phones in AU are locked by law or something like that.
Thanks a zillion...
well hello i need help unlocking this phone i downloaded the unlock app from the play store and nothing also downloaded the code generator and nothing is there a custom rom or something i can unlock this phone or another method thanks in advance... the galaxy is from claro puerto rico
FW update needed to unlock?
I am searching for a way to unlock my I9000T that I bought from Claro Guatemala last year. I have root access and get an unlock code from Galaxy S Unlock, but when I try a sim from MoviStar I do not get an option to enter the code.
From reading other forum posts I suspect that I may need to install a completly different firmware and then root and unlock the phone. Can anyone confirm which firmware will allow this phone to be unlocked? I don't need any cool mods, just to be able to unlock the phone.
It's a I9000T from Claro, not a standard I9000.
I have an unlock code, I don't need to buy one, but the funky FW from Claro prevents me from using it.
Exito!!!
I'll post more datials later, but I have succesfully unlocked my I9000T from Claro.

Hallo, I recently bought this phone on ebay that I knew blocked t-mobile uk, I upgraded the firmware nobrand, I changed kernel, csc, I tried all apps unlock but I could not, where is the block?
Please anyone has any suggestions?
Thanks.
no one has ideas?
Hi guys,
I need some clarification re: carrier unlocking and how it works. I recently purchased a carrier unlocked G920T, and I was going to start messing with custom roms/kernels and other goodies. My question is: Will the phone revert back to being locked if I do a factory reset or if I unlock the bootloader and flash custom roms?
I'm not a T-Mobile user, so I can't get another unlock code from them.
Thanks!!
The G920T has a carrier unlocked version, which is probably the one you have, not the T-Mobile one. Even if it is, usually a carrier unlocked device will remain unlocked forever unless it was unlocked using a different or hacky method, then there is a possibility that it will relock

Yeahh go ahead, mess with it. when it is carrier unlocked, the software doesn't affect it, unless it is a hacky method like @serio22 said, but there isnt such hacky method for the GS6 so have fun.
If it is a G920T (the T means it's from T-Mobile), then carrier unlocking is not a guaranteed state. I paid T-Mobile the full price to get my GS6 and they "permanently" unlocked it. Then after a OTA software patch all of a sudden it locked itself again and I couldn't use my phone for 2 days while they tried to unlock it. T-Mobile's new device unlocking uses a new system which has the phone "phone home" to their servers to check if you're allowed to use it outside of their network. It happened again when I accepted the Android 5.1.1 OTA. So...beware of T-Mobile's not-very-permanent permanent carrier unlocking.
I am living in india..
My relatives brought me the t model ( i wanted f model instead of i sold in india for quicker updates but got t model...lol )
Anyways,
The moment i inserted my sim, it worked like a charm so its unlocked at the moment.
I dont know how they made payment their or how it was unlocked, but the way used must be legit coz its still stock at the moment without root / recovery etc. .
I read humo saying it can get locked again...
My main question, what are the odds of that happening?
Also since i live in india, i wont be able to contact t mobile via phone/walk in, are there ways i can get it unlocked again?
I dont have the bill too if it matters
i believe they have an app that unlock ur device since that is how i unlocked mine. if not u can try to contact customer service online since u r not in US.
With device unlock app , will i have to pay for unlock my s6 g920t or it'll unlock my device for free.
I have an unlocked s6 tmobile from usa, i heard the flashing stock rom will relock the device.
If the phone will relock then how can i unlock it again?
I'm not sure about flashing a stock ROM relocking the device. Mine re-locked when T-Mobile sent Android security patches. This week I did the Android 6.0 OTA update and it has remained unlocked.
Hey guys! i have a factory unlocked version of s6 tmobile, my question is if i can flash the tmobile MM firmware . My model says "country: cellular south" and the firmware country says us tmobile, so i dont know if i can flash without any problems, (Sorry for my english it sucks) thanks !

Code:
SW REV. CHECK FAIL DEVICE: 5 BINARY: 3

You can't downgrade your bootloader so you'd have to pay to unlock it unfortunately

Got it done remotely!
I have a Galaxy S6 (SM-G920T) from T-Mobile. It was locked. But it has an "Unlock" app installed by default. I used it and phone was instantly unlocked! Fast, easy and free!
I used to live in the US for a year and bought a g920T. Since i had the requirements i Unlocked and came back to my country but because of a problem, I had to install a stock firmware and now the unlock is gone.
So i'm wondering, if someone with a unlocked phone made firmware backup, remove the IMEI, and send it online would it work? I mean, right now it works just fine, so i can backup my IMEI and ID and just restore it if needed.
Please help

Have you tried with the tmobile device unloced app.? If that doesnt work then head over to this awesome guy, he can help you unlock it remotely. https://forum.xda-developers.com/tmobile-galaxy-s6/general/sim-unlock-honestly-free-t3601740
Hi all, I've recently purchased my P10 which was locked to UK EE network. My SIM is on Three. A purchased a SIM Unlock code, but unfortunately it comes back as unsuccessful each time.
My question is whether this has anything to do with the firmware I flashed? I initially upgraded it to the Oreo release based on the instructions in this forum, then flashed a treble image. Would I have to simply revert back to the original firmware in order for the SIM Unlock to work?
Please help as I need this device working.
TIA
