can I buy a unlocked, but soft branding SGS (branding T-Mobile or Vodafone), if I
want to update to new android versions (without waiting for T-Mobile)
maybe want to root my phone
or should I buy a more expensive, but without any branding phone?
any tip is welcome, Frank
If it's unlocked that means you can use any sim card, no matter what the carrier.
With the branded firmware, all you have to do is flash an unbranded firmware/rom and you're good to go.
You don't need to flash an unbranded firmware/rom to be able to apply a lag fix or root but who likes branding when you can easily flash a non branded firmware/rom?
I would say buy the unlocked but branded phone. It's cheaper and easy to flash.
howto get and do this?
hmm, I am really new with android
sorry for the silly question, but what is the easiest way to get an unbranded firmware/rom and howto easily flash this ?
and how can I backup old branded version, in case of guarantee ? I think a flashed phone will not be supported any more, or?

Got two virgin sgs with froyo 2.2, i9000UGJL2.
what are the steps to unlock,root,install CWM and update to latest or apply doc roms.
i read everywhere but i kept on getting errors.
it's the same as the Bell phone
by the way Virgin is Bell owned
the unlocking apps dont work and i cant find cwm for 2.2 but only for the 2.1.
I downloaded Galaxy S unlock from the market and unlocked my sim. The app allows you to rewind just in case you need to rewind for any reasons i.e. warranty etc. My phone's sim was locked on to Vodafone UK but now it accepts any sim card
When i try rooting, it says verification error.
use the superoneclick rooting app on the DEV section of the forum
okay.worked on 6th attempt.mod can delete this thread.thanks.
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 !

How did you solve this? My phone stopped working flashed newest (G920TUES5DPK1_G920TXAR5DPK1_G920TUES5DPK1_HOME.tar.rar) and i can't go to older version as that gives me ;
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. I am new on this forum and don't know much about rooting and the requirements of such high complex stuff. But I have an ATT unlocked phone which I use on t mobile. It's lacks WiFi calling, whxih I want, and the signal is probably 1 bar lower than it should. Not to mention I can't update my software since ATT servers for the update won't communicate with my phone since I'm no longer and ATT customer and they are generally very slow with their updates
Anyway is it possible to put a international ROM, say the new marshmallow ROM, or even a T-Mobile ROM on my phone? How would one do that? I am aware of odin as I use it to update my software from time to time. Do I just get the international or T-Mobile ROM and flash it?
Thanks.
No way , at&t have a locked bootloader, ):
international..any day..dont even think abt it
Been trying to do this forever. Still no luck.
Anyway to unlock the bootloader? Would my best bet to sell the phone and just get the unlocked one?
AT&T no way , yes get the 925f
Hi guys, I have been reading for days but can't seem to find a concise guide. I am trying to use a Metro PCS SIM card in a locked TMobile S6.
I have installed twrp and root through Odin, but I can't manage to download the G920T1 firmware anywhere without it failing and forcing me to pay. I have tried sammobile and others.
After I flash the G920t1 firmware will his metro SIM card just work or do I then have to do a SIM unlock as well? Do I use a TMobile or MetroPCS unlock code if I need to SIM unlock?
Also does anyone know of a ROM that will allow me to use his Metro SIM without any of the above nonsense? I downloaded a ROM but I only have my Verizon SIM to test and it asked for an unlock code.
Any help is appreciated. Thanks in advance!
EDIT: After checking Android file host I found a link to the latest G920t1 firmware. Downloading now in hopes this gets me one step closer. https://www.androidfilehost.com/?fid=24591000424951428
Well I got the Metro PCS software running fine and when following this guide on unlockbase it says I just need this TMobile/MetroPCS unlock code and to put in the new SIM card and it should work.

Will report back later this week after purchasing the unlock code and attempting to input it.
One other note is when booting to stock recovery it warms me of multi csc. Its my understanding that this interferes with OTA updates. Is there anyway to fix the multi csc so my friend can take the metro pcs OTA updates or will I have to manually update them for him each time a new one comes out?

Your best bet is leaving it on tmobile rom.. if it's unlocked it's unlocked the sim will work just fine... just because you're using a different sim doesn't mean you gotta change roms
Leave it on what the device actually is, and let the unlock code make anything work for you
The S6 development is pretty dead and you will only really find updates for ours first, and if it's an original Tmobile device.. keep it on that, it's unlocked to work with anything but you don't have to flash anything specific to it G920T Use tmobile stock rom, unlock it and move on and do your business.. install twrp, get root , maybe a custom kernel and or rom?
If you root and leave stock recovery you're gonna have deep sleep issues, there hasn't been any MAJOR updates in awhile and it's only gonna go slower and slower with our device getting replaced by S7's and Note 7's
Roms will be updated to newer firmware bases, and JUST the bootloader and modem files will be online to quick flash within 2 minutes in odin to be updated then flash a updated rom base to the newer firmware if any future releases come.
Don't know too much about CSC sorry about that, but hopefully I at least get you on the right track?
The phone is locked. TMobile has the SIM unlock from the dialer disabled on the s6 firmware. You have to go through them to get it unlocked which my friend is currently unable to do, due to issues with payment on his account. I checked his imei and it says it's all good so I assume a traditional SIM unlock using the Metro pcs software should work.
I wasn't going to root or install twrp as this friend has no need for either and is fine staying on the stock software.
