I just inherited an ATT Note 4 N910A from a family member. It has Android 5.0.1 on it. I was able to unlock it (thanks ATT!). I would like to use it on T-Mobile. I have the TMo SIM installed. The phone hasn't been activated yet. From what I've read so far, the ATT bootloader is locked, so I can't install any CM ROMs - is that correct?
Some questions for those with much more experience than me
- I assume that the phone will update to 5.1.x. Will it install the ATT software also, even though it has a Tmo SIM? If so, is it possible to delete bloat (ATT specific stuff, etc)? What specifically is the bloatware (which apps)?
Thanks much for any help/guidance.
ATT 910A- No root, no unlocked bootloader, no roms. You can run it on T-Mobile, but without an ATT sim, you won't get any OTA updates. You can Odin or Kies the 5.1.1 update.
You won't have root but you can still freeze Bloat. http://forum.xda-developers.com/showthread.php?t=2998294

I have an unlocked AT&T_ S5 with a T-Mobile SIM card. I want to update to lollipop and my phone won't update automatically through my settings so I suppose I gotta d/l and update but which update do i d/l? AT&T or T-Mobile?
The at&t s5 (SM-G900A) variant has locked bootloaders, meaning you can't flash any other ROM's besides the stock att rom, unlike the rest of the T-Mobile or other s5 variant communities do. At&t hasn't released the lollipop update yet, and they released an OTA update, still KitKat, recently. So head on over to the att section of the forum and you will see there is a safe strap method available, but I haven't personally tried it.
I'm looking to get an Galaxy S5 for AT&T, and am wondering how I would update my ROM when using the G900T (T-Mobile)
My understanding is that the G900T comes with unlocked bootloader. I would be getting that model for specifically that reason "just in case" - i.e., if down the line I want to use an alternate ROM.
In the meantime, though, I want to use whatever the most "official", straightforward (i.e., "most approved") ROM I can, even if this means being "behind" on the latest and greatest.
Does this mean that I use the T-Mobile ROM? Or the AT&T ROM? Can I update OTA (as is my preference)? If not, what would be the most straightforward method of updating the ROM?
you would need to get a sim-unlocked G900T, and then you can just put your ATT sim inside and it works.
Not sure if you'll receive any OTA updates if you're not using a tmobile sim though. Most of the newer phones are already on 5.x, you you'd be pretty current.
I got an unlocked G900T last week and put a custom touchwiz rom on it from the att dev section, and it works just fine.
I'm new here but have been following xda for years. I'm not new to rooting or flashing custom roms but after a few days of searching I can't find an answer to the following question.
I have and unlocked Verizon Note 4 n910v running Android 4.4.4 on the Cricket (AT&T) network. If I'm going to install a custom rom, do I need to find a rom for Verizon or for AT&T? Also can anyone clear up the rumor about a locked bootloader on this device? Any help would be awesome!
If you have already unlocked the bootloader on the 910V, I'm not too sure what rumor you are referencing regarding a locked bootloader ::
As far as roms go, it's a Verizon device so you need Verizon roms and firmware.

For ROMs, you must install verizon ROMs because the phone uses verizon-customized hardware.
It is no rumor that this device comes with a locked bootloader. However, thanks to the talented devs here at XDA, there is now an official way to unlock the bootloader; but you have to update to Lollipop 5.1.1 and BPA1 baseband.
I'm using a T-mobile sim in my verizon note 4 without unlocking the bootloader on lollipop and BPA1, so you shouldn't worry about your sim not working after updating. Have fun!
you have a misunderstanding of unlocked. what you are referencing is that you are using the factory unlocked gsm portion of the modem in the verizon model phone. you are NOT bootloader unlocked as you are still on 4.4! if you want to truly unlock it (as in the bootloader) then you will need to upgrade to 5.1.1 (BPA1) via odin. There are several tutorials on how to achieve this, and unlocking (including one that i wrote on the main thread).
to answer your question about using a verizon rom or a t-mobile rom, you can try any snapdragon rom that you would like, but there is NO GUARANTEE that they will work as each developer compiles with or without certain components. what ever you do, do NOT try to flash other carrier (at&t, t-mobile, sprint, etc.) firmware. BIG NO NO! although you claim to have experience with rooting and flashing roms, i would advise you to ALWAYS stick with the carrier variation of whatever device you are working with until you get a better understanding of the different components to a phone i.e. bootloader, modem, rom, etc. xda-university has a nice explanation of these things. so go read up on these things. if you need help, feel free to ask.
Thank you for everyone's advice. Upgrade to lollipop via Odin and bpa1. Got it. As far as custom rom goes, use a Verizon carrier custom rom.
I recently activated my SM-N910A on my new T-Mobile account. The phone was out of contract, so I asked AT&T to unlock it, and they did. The phone is working properly with my T-Mobile SIM card, albeit on the AT&T firmware.
Is it possible to replace the AT&T firmware with a stock Samsung Firmware, or, at the very least, with the T-Mobile branded firmware (for SM-N910T)? I understand that the bootloader is locked on these AT&T devices. Is it possible to unlock the bootloader and load a different firmware onto the device?
AT&T firmware has SO much bloatware, and I've not had any luck finding a way to root the phone on this firmware, so I'm stuck with all that bloat. What are my options here? Thanks!
EDIT: The phone was updated OTA to Marshmallow (6.0.1) when it was on the AT&T network. Build number is MMB29M.N910AUCS2EPH7
I have a question. I have the Unlocked AT&T Samsung Galaxy S8 (didn't realise it was AT&T until I received it and turned it on) and when I go to update the software it says it is up to date but it is not. How do I update my software? I am not rooted or anything, the phone is in its normal state.
Is it an unlocked S8 with AT&T firmware or an unlocked AT&T S8? Also, what carrier are you using?
Either way, you can use Odin to flash the newest firmware. Search Updato.com for the firmware for G950U (AT&T variant if you want bloat) or for the G950U1 if you want actual unlocked firmware with no bloat. However, the newest that they have posted if CRF5 and CG3 just came out the other day.
I asked about carrier because:
If you're running on Tmobile for example, use the tmobile firmware. You'll have bloat but you'll get all the features and you'll be good to go on updates.
If you're using Tmobile and want Unlocked firmware download the TMO coded U1 firmware and again, you'll be good with updates.
@jpcdeux I would think it has AT&T firmware because it came with a few AT&T apps on it. However, it is not locked to at&t so I am able to use it in my country (St. Kitts).
Would I have to root?
No, rooting is not required to flash unlocked firmware
Thanks much @jpcdeux
