Once you unlock with the MetroPCS firmware, do not ever flash back to T-Mobile firmware, or you'll end up relocking it! You can flash any compatible ROM, just not the T-Mobile radio firmware. ROM'S never include the radio firmware, so you should be fine.

Ok and really quick, lets say I used the unlock app to get a temp unlock and froze it to kind of make it perm could I flash another ROM and still be unlocked?

No, it's not that easy! You need a real unlock to make it permanent.
You just need to decide which route to take to unlock it.
I did the MetroPCS firmware and then traditional sim unlock, and then custom rom.

But what if I went back to tmobile stock and then I would lose the unlock BUT after going to the tmobile rom which would make me lose my unlock could I go back to a metroPCS ROM and unlock with the same code?

No, It's the low level firmware that's the key to the unlock.
MetroPCS firmware = traditional code unlock
T-Mobile firmware = proprietary device unlock
After you're unlocked, you can change the ROM all you want. It's the low level firmware that you must be careful with (mainly the radio).

Do you mind pointing me to the guide you used to root and install recovery on your S6.
I just unlocked mines using the metro firmware and I don't want to accidentally install the T-Mobile firmware
Thanks

Don't download and Odin flash the T-Mobile firmware or radio, and you'll have nothing to worry about!
Rooting is simple on an unlocked bootloader if you don't mind tripping knox.
1. Odin flash TWRP.
2. Boot straight into TWRP after Odin flashing (vol-up + home + power)
3. Flash SuperSU from TWRP
Done, profit!

Hey! I do have the same question as the person that created this thread. When I flash the MetroPCS firmware should I select MetroPCS or T-Mobile on a 3rd party unlocking company to buy the unlocking code? Thank you all!

MetroPCS, that's what I did and it worked fine if you flash the MetroPCS firmware.
I need to get my S6 to show the Tmobile Logo on bootup so I can Jump to the S7. I had flashed it to MetroPCs for the unlock. I thought if I went the Odin route and installed the Tmobile software it would change the bootup Logo but so far after running Odin it still boots up with MetroPCs.

Which MetroPCS firmware did you use and where did you get it from?
I have a SM_G920T on TMobile 5.1.1 Baseband G920TUVS3DOJC and I tried flashing the G920T1UVU2COF9 MetroPCS firmware from sammobile and I get a FAIL message on Odin.

I Odin'd the MetroPCS firmware (G920T1) a long time ago, and it was newer than the TMo firmware the device had on it at the time. I think you're failing to flash because the MetroPCS firmware you used 2COF9 is older than the Tmobile firmware 3DOJC you already have on it. That's my guess.

Modem issues

Alright well I flashed the new COF6 modem on 5.0.2 AOCG and when I make calls it takes a good 30 seconds or more for the call to go through, sometimes it won't even go through. Incoming calls are hit or miss, sometimes it just says the wireless caller you are trying to contact is unavailable.
So I tried to odin back to the AOCG 5.0.2 modem and is passes in Odin but then when the phone boots up it says baseband unknown with a X through the signal bars. Tried to odin the full 5.0.2 firmware and same thing, unknown baseband. I did a full wipe before I tried the full 5.0.2 firmware. Not sure what's going on. Any help is greatly appreciated!

Are you shutting the phone down manually and booting into download mode?
Yes, tried both ways, manually and booting DL from TWRP. I Just odined the full 5.1.1 and now I lost domestic sim unlock, what a PITA.

Just remember to never flash a T-Mobile radio, or it will re-lock the sim!
The Metro radios work fine with T-Mobile and AT&T networks.

Yep read that a while ago. Seems like to be about the same if not better signal than the T-Mobile radio. :good:

Q: Unlocking phone for international use

I received an unlock code from AT&T to unlock my phone for use with other carriers so that I can use it when I travel outside the country. But it's not working for some reason. Here is what happens:
Turn phone off
Take out AT&T SIM card and replace with friend's T-Mobile SIM card
Boot phone completely
Phone automatically prompts me for unlock code which I enter
Phone goes to home screen
Phone prompts me again for unlock code
I tried 3 times and stopped trying because after 5 attempts the phone supposedly permanently locks to the AT&T network.
I AM rooted running CM13. Is that the issue? If so, what do I need to do to get the unlock to work? I tried searching but I'm only seeing results related to unlocking bootloader, etc, not surprisingly haha. Thanks!
Your system must be totally stock to SIM unlock the Nexus. Flash a stock image.

Okay to keep bootloader unlocked and keep root? Just need the stock ROM?
And then once I flash stock image and unlock SIM, okay to reflash CM13? And the SIM will remain unlocked?
Thanks again!
I wouldn't bother with root on the stock image since you'll be reinstalling your custom ROM afterward, but you can keep your bootloader unlocked without worry. Once SIM unlocked, the Nexus stays unlocked.

[HOW TO] Flash U1 firmware to U device

First of all, thanks to Raymonf (I dont know his XDA Username) for making these Odin files. This new version of modded Odin allows for flashing custom and official tars AND also compressed binaries, which Samsung will be using in all Odin firmwares from Oreo on.
Oh and doing this doesnt wipe data if you do exactly what I wrote below.
1. Download your devices firmware from below
2. Enable USB debugging by going to settings > about phone > software info > click build number 7 times and enter your password
3. Open command prompt on your PC and type adb reboot bootloader
4. Open odin and select the AP, BL, CP, and HOME_CSC file in their corresponding locations
5. Start it
6. You are there!
To go back, do the exact same thing with the U firmware files!

Thank you for this. In all of the download mirrors for the s9+ the free download is unavailable. Is it asking to much to upload to a site that will offer free downloads?

The modded/patched Odin has the model-ID and SHA hash check disabled, therefore allowing you to flash an unbranded "U1" firmware onto a branded "U" phone and vice versa.
As of now this works on most US Qualcom (QC) models, but an increasing number of international Exynos (EX) models now include a new RMM security which prevents this kind of cross-flashing unless you first disable the RMM, by flashing an RMM-Disabler package through TWRP.

Probably gives better chance to root huh?
What I'm not clear on is: after I flashed my factory unlocked s9 to the VZW U firmware to see if I could get video calling to work (it didn't) then flashing back to what has been described as stock U1 ARBG firmware, in my about phone it still says VZW/VZW/XAA. Is this set by the SIM. Will this only change when I put a different carriers SIM card into the phone?
Question, before i dive in...
My UICC is locked to Sprint right now (damn 50 day limit) and I was wondering, if I flash this U1 rom, would I be able to edit the APN? Has anyone else done this?

That's correct, the unbranded "U1" firmware sets the carrier parameters based on every different carrier sim card inserted.
Don't worry about the VZW/VZW/XAA, for all intended purposes the phone acts as Verizon phone.
It's just a flag, but if you can't sleep over it then do this while rooted:
adb shell su -c echo "VZW" > /efs/imei/mps_code.dat
adb shell su -c echo "VZW" > /efs/imei/omcnw_code.dat

Flashing the unbranded "U1" firmware will neither unlock the network nor the APN settings if you keep using a Sprint sim.
On the other hand, if you unlock the network and insert an AT&T or Tmobile sim then you should be able to edit the APN, but then again you don't have to edit it because it gets set automatically based on the type of sim inserted.
Thanks a lot, quick question, i have an at&t "U" model, manage to install the U1 software (wanna get rid of all the at&t apps), everything its working just fine, but when an update comes to the U1 model, can i install it the regular way on odin, or do a need to follow this steps again??
here's the link i use from another post to dowload the system a bit faster: https://androidfilehost.com/?w=files&flid=257047 greatings to the author.

Wait do you have the same XXA unlocked model variant and tried flashing it? I'm also assuming that YMMV means "Your Model May Vary"..

Your Milage May Vary. I have a factory unlocked S9. When you flash firmware there are risk, don't hold me accountable if your Knox gets tripped some how. People hose their phones in flashing accidents then say someone gave them wrong info.

I wouldn't blame you lol, yes I know there's a risk. But you have stated earlier that you flashed a firmware and it didn't trip knox, so I'm wondering if you flashed a carrier firmware "U" on your SM-G960U1 device..

I'm glad to report that after flashing the Sprint firmware on my unlocked S9+ worked no issues and knox was not tripped. Now I've noticed that even though the Sprint splashscreen didn't show up at boot, while in setup the phone did detect the exact carrier I was on (Boost Mobile) and the phone showed the Boost Mobile splashscreen upon reboot and all the Boost Mobile apps as well as some bloatware loaded onto the phone as if it were a phone I purchased through them.
So if I flash my tmobile device to the u1 firmware can I then root my device and put twrp on it?
Is any root method available for the t-mobile version?

Question Flashing/Unlocking Bootloader eSIM

Hello,
I bought the pixel 7 from Orange F, France. I am using two SIM such as Orange F on eSIM and sim card slot for another number. I want to root and flash custom roms without losing eSIM. I didn't try yet but there is no option to recover eSIM in the Orange F website. I searched on it, generally they said there is no way to lose the eSIM if not intentionally selected during factory reset with factory images etc. But is this the case for also flashing custom roms or flashing other scripts? Or is there anyway to backup eSIM?
Thank you folks.

Same here. The eSim sticks through resets, and roms at least in my case too.
