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.
Since theres no straight forward answer and the guides seem to be all over the place i was looking for a straight forward answer.can this be unbranded to like the dev edition or something else?

Here is about all I can find from someone reliable.
http://forum.xda-developers.com/showpost.php?p=68150390&postcount=866
--To me this says - it should be fine to flash the full US Unlocked RUU/firmware, which is x.xx.617.x, I think the latest is 1.91.617.1
I personally have flashed the pmic-8996-1.img from multiple firmwares including, International, US Unlocked, and Tmobile testing out WiFi drain. So, some bits are ok, but the aboot.img (bootloader) contains the partition, so anything other than VZW or the US Unlocked could result in a brick.
Until someone takes the plunge and reports back, or unless their are people out there whom have done this but not seen the posts asking the question. So hopefully if they are out there they will see this thread and comment.

Reviving this to ask a related question:
Can I safely flash the latest U.S Unlocked radio to my VZW 10 which has the latest VZW firmware?
If you flash the unlocked radio you will most likely lose all your verizon features such as volte and so on I would not if you use verizon services. For what purpose would you want to may I ask ? If you want to run your Verizon version on At&t or Tmobile there are threads on both I believe, but you should have support for other carriers already I believe as I think you will just get a non Verizon sim message is all but AndyBones can direct you on how to remove that nag.

I'm not actually using the phone on Verizon network, I bought it second hand and using it on Rogers network in Canada. Everything runs fine including LTE, but reception is weaker than on my M7 (purchased from Rogers) hence my wanting to try the U.S Unlocked radios to see if things improve. Similarly voice call quality is not that great though it has improved with the 1.82 firmware upgrade.
I don't mind testing out the radio myself, just need some assurance about being able to without bricking the device due to firmware mismatch or other incompatibilities. As pointed out in this thread very little information exists out there from people who have unbranded their VZW 10s or flashed non-VZW radios.
Have you tried running the latest RUU for the Verizon HTC 10 ? This may fix your issue if you have not already. Also I think on another thread Dottat posted a method to reset your bands of some some if you look on his thread for being able to use the unlocked 10 on Verizon he has it posted on there I believe. Resetting the bands or modem has worked for some people with issues with signal.

I'm not having an "issue" per se, I just want to see if I can get improved reception with a new radio, so I don't think an RUU flash would change much (I have already reset my modem for a separate issue).
Thanks for your help, I'm hoping that andybones or another dev can answer my question about being able to flash a non-vzw radio safely.

Is Rogers a CDMA based carrier (I legit don't know). You may need to do an entire us unlocked swap, not sure if anybody has tried that yet with a vzw phone.
No Rogers is a GSM network but my VZW 10 works fine on it.
If by debranding you mean to convert it to US Unlocked version, then Straightforward answer: Yes. You don't need to read further if all you needed was a yes or no, but I felt I should post what I did to convert it to US unlocked from Verizon for others who might need help.
Verizon 4G LTE devices are already unlocked. So, just to be sure, I S-OFFed my device first via sunshine. While S-OFFing, I chose the option of S-OFF with locked bootloader. Then I changed the CID to BS_US001. Didn't have to change the MID as it was the same as US unlocked version, i.e. 2PS650000. Flashed latest TWRP (for nand backup just in case). Flashed US unlocked RUU 1.8X.617.X. Successfully updated to 1.96.617.2 via OTA.
One thing that I immediately noted after converting to US Unlocked version was that the option of OEM Unlocking which was previously not present in the Verizon version became available in the Developer Options. Hope it helped.

Hi GrimJoke,
Thanks your post! Since I last posted here I've managed to do exactly as you described and ran the Unlocked RUU, updated to 1.96. Now running stock ROM and everything works great, and in fact the phone runs better than it did on vzw software.
I've noticed the same regarding OEM Unlocking. I read from Captain Throwback here that we should now be able to unlock the bootloader with htcdev and with superCID 22222222. I won't try since it's pointless for me.

how about from Verizon to complete wwe using wwe radios for international gsm network?
does volte work with tmo, att etc after gsm?
Here I discovered a new firmware for N5120:
https://samsung-firmware.org/download/GT-N5120/wo45/NEE/N5120XXSDQC1/N5120OXXDNE1/
Phone Samsung GT-N5120
Model GT-N5120
PDA Version N5120XXSDQC1
CSC Version N5120OXXDNE1
PHONE Version N5120XXDNE4
Region NEE
Country Nordic countries
Build Date 30.03.2017
Changelist 1600517
OS KitKat
OS Version 4.4.2
Updated OTA:
new kernel and new security patch:
I am tired of dealing with SGH-I467's (AT&T only) locked bootloader. It makes installing custom ROM impossible. Now I'm thinking of buying and swapping in a mainboard from SGH-I467M (the Canadian version is bootloader UNLOCKED) or GT-N5120 (international version).
1. will this give me an unlocked bootloader without any other hardware change? I know I probably have to swap in a new modem code, but with an unlocked bootloader, any software change is possible
2. will the mainboard from GT-N5120 work in a SGH-I467? I know SGH-I467M's mainboard will for sure work in SGH-I467 because the only difference is the latter has a locked bootloader. Unfortunately, SGH-I467M's mainboard is hard to come by, but GT-N5120's is still available. Although the LTE bands in N5120 are overseas and SGH-I467 has AT&T bands, are they really different hardware, or same hardware with different software?
[Updated Feb 9th, 2018] Now I don't think it is doable at all to download SGH-I467 or SGH-I467M's modem code to a GT-N5120 hardware even if the bootloader is unlocked. I have a Canadian Galaxy S4, SGH-I337M (bootloader unlocked, unlike the AT&T version). Since my carrier is U.S. T-Mobile, I tried to download T-Mobile's modem to my S4 thinking it may give me better data rate. Odin prompted Fail! (Auth) and S4 showed Secure Check Fail! After some googling, I realize regardless of unlocked bootloader, these phones/tablets are engineered to check if authorized modem codes are being flashed. I know for sure my S4's bootloader is unlocked because I have installed TWRP for recovery.
Since GT-N5120 has international frequency bands, turning it into a North American tablet is DOA if another carrier's modem code cannot be installed. If anyone questions why a custom ROM can be flashed to a phone/tablet with unlocked bootloader, it is because a custom ROM seldom comes with the modem code!

That firmware is almost year old now..
I have no issues with my at&t i467, it runs and does everything my modded Note 8.0 does. Except a lack of custom recovery, and kernel. All you need is to learn a bit on simple file managment and permissions, while plugging away with dropping in system files and libs. I guess I will be the only one here with a modded out yank i467 that works on EU wifi channels.
I had a few threads on libs and apps, along with settings config files to customise on your own. But everybody acts like it's complex trig. Heck i hardly knew much about android when I bought my tablets, and in a years time peeps think i am a god. WTFF!

Great idea! Thank you. Says who one has to do all mods during the Odin time and get rejected by this locked bootloader? I will definitely look up your threads on how to swap out these files post boot.

Hello to the XDA Community, I recently made this account and would like to get some help from the great people here.
I own a Verizon Samsung Galaxy S7 G930V. I, unfortunately, found out the hard way that it could not be unlocked because Samsung decided to lock down the bootloader on it (something that they were a bit more lenient with on the Galaxy S8, I think?). Either way, I was reading this XDA article (https://www.xda-developers.com/galaxy-s7-bootloader-lock-explained-you-might-not-get-aosp-after-all/) about the bootloader, and it basically says that, despite the OEM Unlock option being available under Developer Options, nothing that doesn't have some sort of official signature can be flashed to the device, so it's basically pointless.
But, then I saw that LineageOS dropped official builds for the Galaxy S7. My only question, therefore, is: why would Lineage OS drop custom ROMS for a phone that cannot have anything flashed to it? Am I missing something? Not sure what I'm missing. Just to clear things up again: I have the Verizon Galaxy S7 G930V (Snapdragon). I am also using a T-Mobile SIM in the phone, not sure if that matters or not, however.
So, what I assume is that somehow people were able to get past the bootloader and that is the reason that LineageOS released official builds of their ROM. If that's the case, is there a method/tutorial for, first, unlocking the bootloader and rooting the Verizon G930V, and then installing the custom ROM successfully? Also, I see that LineageOS does not have a build for the G930V specifically, so would it brick my phone if I installed the build for the G930S, for example?
Thank you guys! Bare with me if I completely missed something please!

There are numerous variants of the GS7 and GS7E that have a bootloader that can be unlocked. The Verizon version is not one of them. There is no way currently (and likely ever) to unlock the bootloader on the Verizon version of this phone. This is the case with almost every Verizon phone. People are finding this out the hard way with the new Google Pixel 2's...all versions other than the Verizon one you can unlock the bootloader. It's a Verizon thing and it won't change. You'll need to buy an unlocked phone capable of running on Verizon's network bands if you want this kind of stuff on Big Red.
This may be a rather basic,question, but I'm trying to play it safe so I don't brick my S10+ (SM-G975U). Can I download an official Tmobile Android 10 ROM and flash the phone with it? The phone is not rooted and the bootloader hasn't been touched (at least by me).
I purchased an unlocked AT&T device and use it on Tmobile without issue. I am not, however, receiving any updates from AT&T or Tmobile, so I'm looking to update to Android 10.
Is this possible?

Yes, you can take any official carrier firmware made for the phone and flash it with the patched version of Odin. The bootloader has to match though. If you're on bootloader 2 you can't flash a bootloader 1 ROM. You can even flash the unlocked Samsung U1 firmware. You can also jump from Android 10 back to Android 9 and then back to 10 as of late. The phone can't be rooted nor can the bootloader be unlocked.

Thanks for the quick reply and I appreciate the guidance. How would I know what bootloader I am running on my device currently and what version of bootloader the ROM is?

No problem. To find out your bootloader go to settings, about phone, software information. Look under baseband version and you should see "G975USQU2CSKP" or something along those lines. The 2 right before CSKP is your bootloader version. If it says 1 instead of 2, then you're on bootloader 1.
