I have a samsung s6 g920p,bought 2nd hand.
I have reason to believe it is unlocked cause i use a different sim and i am not in America.
But i have a problem i am currently running a 6.0.1 G920PVPS4CPK1,i want a 7.0 update,apparently i would have to do it manually with odin cause the software update doesn't click.
Which ROM do i download to avoid a relock and any or other complications. ?
Please guide me.

I downloaded Odin and an N9005 firmware( i think) is it compatible on N900T? the phone(T-mobile) is unlocked here in the PH unfortunately i didnt have the chance to see what the technician did or the software he used in his computer. since my phone was modified i wasnt able to upgrade it through the phone itself.
will my phone be able to remain unlocked if the custom OS install is successful?
use the tmobile stock 5.0 rom on sammobile.com for the note 3/sm-900t
My friend's AT&T Galaxy S3 (SGH-I747) was unlocked at 4.1.1 stock and now I installed Resurrection Remix (7.1.1). Now when I insert my sim there is no network but it recognises that there's a SIM but no carrier or whatsoever
Is my phone now locked or unlocked?
I live in India
Baseband - I747UCDLK3
Bootloader - I747UCDLK3
I have to return the phone by 10th March
I'm a novice, however in my experience once the phone is unlocked it stays unlocked no matter what rom you install. Perhaps another rom may work better in your situation. LineageOS seem to work well for my needs (with unlocked phone) and you should give it (or others) a try.
You may have lost the IMEI and will have to ODIN back to stock to try to get it back. Also, you can search for IMEI in the forums.
Check in about phone status under settings to confirm you lost the IMEI before all this.
I would flash it back to stock 4.1.1 from Sammobile.com with Odin.
7.1.1 roms will require the latest bootloader and modem to work.
It may be too late now but your main reason for lack of success is your "bootloader_modem" you are currently 5 or 6 places behind the latest release! Its very old and these ROMs require the latest bootloaders: I747UCUFNJ2 for Android version 4.4.2. Check out "enewmam17" threads on XDA for how-to and links to .zip files. Hope this is not too late to help in any case it's good for future reference.

So I have a SIM locked S8+, I flashed it to the unlock firmware to debloat, and to see if it will SIM unlock the device (it did not!). Now I have T-Mobile unlocked the device and received the typical email of "the device is unlocked, no unlock code, need to run Device Unlock App to unlock" email.
The issue is, with the unlocked version firmware, I cannot run the Device Unlock app, it simply says the app is not compatible with the device, which is right because you cannot unlock an already unlocked device, seeing that a device is running an unlocked version of the firmware.
Two questions:
1. Do I have to revert back to T-Mobile stock firmware in order to run the Device Unlock app?
2. If so, how to revert back? I have see this can be done for the S8, but have not seen instruction (files) for the S8+.
Thanks!

I have the same question too since I was contemplating on whether I should update my T-Mobile S8+ to the unlocked firmware but then I wondered if I could go back to stock T-Mobile firmware. Seems like no one has an answer for this yet : /
You can revert back 100%

If you flash T-Mobile Unlocked Firmware 955U1 yes you can revert back by just flashing T-Mobile Stock Firmware 955U. It was difficult to revert back before 955U1 was released where we flashed Canadian Unlocked XAC, but we finally got a solution as in the link below.
https://forum.xda-developers.com/showpost.php?p=72525783&postcount=5
Again, if you flash T-Mobile Unlocked 955U1, you just flash T-Mobile Stock 955U to revert back to stock. Note: You'll need to switch between unmodded Odin3 v3.12.7 and modded Odin PrinceComsy for Stock and Unlocked Firmwares. Another option which you don't need is reverting back using Smart Switch Emergency Software Recovery Initialization.
Warning!!! When reverting back there's 95% chances of getting a Phone Storage corrupt and the only option is resetting. Meaning you'll lose your data, so backing up your stuff is highly advised.
That option works great ?, just BACK UP and moved files to your SD CARD. I have done it more than 5 times, works great. I haven't UNLOCK MY S8+ yet, I'm getting another one so I'll UNLOCK it. YOU CAN CHECK OUT IMEIFIX.COM OR IMEIGURUS.COM . I have UNLOCK more than 4 S7 Edge, 2 Note4's and these guys work very fast. 100% recommended ?.
Hello All,
Recently I was able to flash my US AT&T branded G960U to the Samsung unbranded U1 version. After I did that, I flashed my phone using an official TMobile Rom, Oreo I believe. At the time, the boot loader was not locked.
Today I tried flashing back to the Samsung U1 firmware and it keeps failing as I believe that my boot loader is now locked which may have been caused by the TMO ROM.
When I did the flashing, I used the Modded Odin v3.13.1 Raymonf version. I tried the exact same steps tonight again and no luck. I tried on two different computers, have the drivers, files, etc.
Any known work arounds or fixes? I want to go back to the U1 version so I can upgrade to the Oreo 8.1 due to alot of bugs in Oreo 8.0
Thank you

Have the same problem here
The reason you cannot go back to u1 firmware is b/c the att and t mobile firmwares are newer and updated the bootloader to v2 hence you can't go back to the u1 firmware which has a v1 bootloader.

Yeah I think I'm stuck too, however I don't mind as all the t mobile bloatware was able to be uninstalled and it's very responsive. Seems as if arc6 (tmb, 960u) is very fast and doesn't have any of the hiccups I noticed on the Canadian firmware (Telus arc1 seemed better but not as new as arc6 and also a one month older security bulletin).
I'm ok with being stuck however, we just need a U1 firmware with the v2 BL if I'm not mistaken.
How do you tell what version bootloader you are running?
