T-Mobile boot.img question

So I flashed my AT&T Note i717 to the T-Mobile boot.img. I think it was "t-mob-stock-boot.img.tar". So now my phone thinks it's the T-Mobile Note version. When I go into about phone, the model number even says SGH-T879.
Will this cause any future problems if I want to flash to an AT&T based ROMs? Will it have any problems if I flash T-Mobile based ROMs? When I flash the radio modems...will only T-mobile radios work or will AT&T radio works as well? I'm just trying to clarify everything before I do something stupid and mess up my phone. Thanks in advance.

This belongs in the Q and A section. As far as your inquiry
So correct me if IM wrong but from mg understanding.............
1. TMobile boot.img
So this is needed to flash any TMobile ROM the reason for this is that it makes the association to the ROM. No boot.img will cause the ROM to not boot up. So TMobile boot.img must be used for any TMobile or att roms if you are using a TMobile note. and att boot.img must be used for any tmkbile or att roms on an att variant of the phone.
2. The radio basically tells the phone what network it's connecting to. So if you flash a TMobile ROM there is a big chance you are also flashing a TMobile radio. If you are trying to use an att galaxy note with TMobile you have to find the appropriate radio in that Dec section. If you are trying to use the TMobile ROM on att network you must flash an att radio.

Got it! Thanks. I have an AT&T note that I'm using on T-mobile...so for future references, there shouldn't be any interference if I decide to flash to an AT&T ROM if I flash it back with At&t's stock.img, correct? So just to double check, I can only flash to a t-mobile radio only if I'm running a T-mobile ROM? What are the side effects if I tried to flash to a T-mobile radio on a stock at&t ROM?

That's about right. I don't think you can brick the device by flashing an improper radio, but don't hold me to it. I have done the opposite I have a TMobile note and have flashed TMobile radio with att roms with various success. In some occasions the ROM boots and the signal varies. It's best if you stick with att roms with att radios as opposed to TMobile roms with att radios. Results will vary by rom

Flashing T-Mobile Firmware to AT&T N900A Variant

Hi Everyone -
AT&T finally gave me the unlock code for my Galaxy Note 3 SM-N900A phone. I'd like the move it to T-Mobile, but have some questions before I do:
1. Is there any way to flash the T-Mobile/N900T firmware to an AT&T N900A variant? I'm talking the official factory firmware...CSC, bootloader, radio, everything needed to essentially do a complete conversion. I'm not interested in custom ROMs based on T-Mobile's firmware and that kind of thing. I assume if there is a way, it's not as simple as flashing N900T firmware in ODIN, since it would probably fail the model checks.
2. Is there any way of enabling the 1700 MHz AWS band for HSPA+ on an N900A? I know it works fine on T-Mobile LTE and will also work on HSPA+ in areas where T-Mobile has refarmed it for 1,900 MHz. I assume the 1,700 MHz lockout on the AT&T version is probably a software limitation inside the modem firmware.
If anyone can shed some light on this, I'd appreciate it.
Thanks!

You can't flash them or you would get hard brick. If that were the case people would have already unlocked their BL's using T-Mobile

Figured.

I wonder why it would hard brick though. With the exception of atts bl being locked, wouldn't it all be relatively the same? Would it be possible to clean up the n900T bl to match the n900a?

Make sure you pay attention to the Modificatinator file and add the T-Mobile carrier file after installation. Works fine and much better than stock ATT junk rom.

Quick question to everybody on here... Is it possible to ODIN the baseband/modem for N900A to the N900T? I want to do this because my service provider is Cricket, which is an MVNO of AT&T. It's not a priority, but is it possible?

Probably, and if it doesn't work you can Odin the stock NC2 or NL1 firmwware back and start again with this ROM.
But why? If you're getting LTE the way your phone is (assuming Cricket is giving you LTE), you won't gain anything by flashing a different modem. (Unless you're getting a lot less signal with this ROM than you were with the NC2 or NL1 modems.)

AT&T Note 3 ROMS on Tmobile version?

I have an unlocked Tmobile Note 3 (running on AT&T network) and I would like to know if I could install roms from AT&T version on it? If so, do I need to do anything special for it?

In my opinion it would be a downgrade. At&t packs it's devices with bloat.
Any particular reason you want an at&t rom?

Cricket Service w/ G920T

I recently purchased a factory unlocked T Mobile GS6. I intend to use it on Cricket. I don't expect to have any problems with that, but will I have problems flashing roms? Can I flash G920T roms?
Thanks in advance

Cricket uses the AT&T Network not T-Mobile

They overlap. An unlocked T-Mobile phone will work on cricket or ATT. I am not concerned about that. I am trying to find out, primarily, if I flash the MM rom for the 920T, will it 'lock' my phone?

need some advice for note 4

Hello I have a verizon note 4 and am using it on tmobile my question is this, Now that the 910v can be rooted what happens if I root it and download a tmobile rom and install it on the phone? Will it work or will it brick the phone? I have no idea if there is any real difference between the verizon note and the tmobile note besides the carrier. Any input would be appreciated as I cant stand the verizon bloatware and would love to have my tmobile stuff back
thanks in advance

As far I know not possible
Tmobile is GSM model and verizon is CDMA frequency bands different.

I did something similar with AT&T G2 and loaded a Tmobile ROM on it. First you need root and TWRP or equivalent. and then some developer have to created a modified bootstack that are tailored for your phone model to work with the rom. Once you load the bootstack, then you load the rom without the radio. Not for the faint of heart.
