Upgrade Note 3 N900A Factory Unlock - Galaxy Note 3 Q&A, Help & Troubleshooting

Hello
I am new to this forum and definitely to the aspect of upgrading the OS. I own Note 3 SM-900A which I bought online. It is factory unlocked. I am using it in India since 2014. There has been no problem ever since. But I have now realised that many apps don't work including Google Assistant on current OS 4.3. I wish to upgrade it. However I face a problem when I try OTA upgrade that no upgrades are available. This is understandable as I am not part of AT&T network.
I guess the only option left is root and upgrade. Therefore my queries:-
1. How does one go about it?
2. Which version of OS do I install and where do I get it form?
3. Do I have to install custom ROM? Can't I simply download pure OS and install it?
Sorry for sounding like a newbie... I am one thought.

Are you sure you are pointing me too the right forum. They seem to be discussing about spotting the difference between the real and fake phones. Mine is not such case.

[Q] UK Orange S4 questions

Hello all!
I posted the questions below on the UK/Ireland thread yesterday, but havent had any replies yet, so trying here for better luck!
My 9505 arrived today, and cant wait to get busy with it! So reposting my questions here, in the hope that i get the answers!
I really need to find out which rooting method is suitable for this device, so I dont screw things up.
Thanks in advance to anyone willing to help!
Hi guys and gals!
I was a long time serial HTC user, and now finally have jumped ships over to Samsung , so going through a learning curve here, please bear with me!
Waiting for my S4 on OrangeUK upgrade to arrive tomorrow, so getting ready for the usual initial steps and have a few quick questions:
1 What is the model sent out by Orange, 9500, or 9505? Its a GT-I 9505
2 On XDA, what is the difference between the "Galaxy S 4 i950x Android Development", and "Galaxy S 4 i950x ORIGINAL Android Development" sections? I dont get it...
3 Is the Orange UK S4 all ok to root, sim unlock etc as we currently stand? Which method is the recommended one?
(I ask, since having trawled the forums previously, have seen that this changes according to latest software versions etc until devs catch up; easier to ask quickly here than read 300 pages and still be confused )
4 Which is the best/easiest method to unbrand and change the carrier designator, so I end up with an unbranded stock/sim free model designator and ROM? Is it worth doing?
Want to get rid of the Orange crapware, AND be able to get future updates, since on my HTC Sensation removing the crapware changed the hash value of the system software, and subsequent updates would never install anymore)
Thanks in advance guys, looking forward to your replies and starting off with my S4!
OK, after playing around for awhile, it seems that happily ive been sent a stock version! ie no Orange crapware etc... :good:
Ive updated the software to i9505xxuame2, with OTA.
Still uninformed as to the best root method to use, so any advice will be appreciated!
Well, no one answered so I tried the following method and it worked great!

[Q] Please help me find the stock rom for my galaxy s4

I was an exchange student in Canada a while ago and I bought my galaxy s4 GT i9505 there, it was unlocked for other carriers, because I live in Brazil, so I bought it and a friend of mine tried to update the OS, but he did put the Google Edition OS on my phone, and now it doesn't recognize my sim card, it's like I can't catch the signal again, anyways, I have 2 main questions:
1-Can I go back to Samsung stock rom and it will be okay?
2-What is the correct stock for the M919VVLUAMDJ baseband version? Does the carrier matter? Because I don't know,because I bought it unlocked

but then,which one should I download?
The VTR,GLW or the MCT one? The thing that bothers me is that I don't know the original carrier, since I bought it unlocked and rooted already

So,they won't make difference if I download them? All of the three up there are going to work on my phone? I'm a noob so...I'm afraid to brick it, and this cell phone is kinda expensive here in Brazil (freaking taxes )

Installing non Verizon ROM on Verison Note 4

Can I install stock non Verizon ROM on Verizon Note 4?

I don't see why not, you would need to do it via Odin and make sure you have the correct Firmware. You can download stock roms from sammobile.
I am amazed buy how much effort you put into familiarizing yourself with forum rules. Clearly Q&A section was made just for fun. I am sure mods wanted everyone to ask questions in development.
To answer your question. I am not entirely sure, but I believe Verizon version may have different hardware so installing 910f version of ROM may seriously mess up your device.
It may be better idea to ask that question in Verizon Note 4 forum...

How to upgrade rooted Note 3 from 4.4.2 to current (Newbie here)

TL;DR Help a newbie with upgrading my rooted Note 3 from 4.4.2 to a more current version please. I'm old and dumb and really tried to find an answer before embarrassing myself on a forum of experts. Knowing me, the answer is probably right under my nose. Go easy on me <3
Hey guys,
I used the search function on this site and on google but was unable to find what I'm looking for.
I have a Samsung Galaxy Note 3 with T-Mobile. I have Android aversion 4.4.2 and my model number is SM-N900T.
I rooted my phone using a guide I found on youtube to get superuser for the purpose of being able to play emulators on my phone, such as Snes9x EX+, Nostalgia.NES Lite, ePSXe, etc. They all work great. I am not using a custom ROM.
The problem I'm facing is that I don't understand if I need to unroot (correct term?) my phone and just get the auto updates, or to download and install them manually, but I'm unable to receive auto updates over the air as I'm sure you guys would know since this is your hobby and are versed in this sort of thing. I don't even know how to do either really properly but am not afraid to try.
The reason I'm wanting to upgrade now (which might be completely unrelated) is that I haven't been receiving text messages from either my sister or my roommate, whom both of their last messages were received by me on Aug. 5th. I tried contacting my carrier and they said they didn't detect a problem. Both of their carriers said the same thing (one being T-Mobile as well). I guess this is just another step in troubleshooting but I would like to believe this is a network issue.
Any advice would help and would be greatly appreciated. Thank you very much.

Upgrade confusion. Note 3, N900A stock to 7

Trying to update my Note 3 to android 7 but running in circles.
Progress:
Downgrade from 5.0 to 4.5
Rooted device
Uploaded rom to SD card*
Boot recovery mode, select ROM file
Run install
This is where I keep going in circle.
It keeps telling me cannot verify file, verification failed. (does this twice)
Then says update successful, wipe data, format etc.
Reboots back to same old V4.2 again and of course the apps I installed to work on phone gone and have to re-register with Play store to get them back.
How do I solve the error "Unable to verify file"
( also is there a way to stop it wiping data every time if it has failed to update anyway?)
*ROM
lineage-14.1-20180110-nightly-hlte-signed.zip ( this may be wrong rom but the names are often confusing me because the links in upgrade note 3 take me to that rom among others so I assume it is for a note 3)
Any help pin pointing the ACTUAL, CORRECT ROM welcome.
Specs:
Samsung Galaxy Note 3
Qualcom MSM 8974
Snapdragon 800 / 2.27GHZ 4 core cpu.
krait 400
r2p0
Pre-downgrade V 5.0

What am I looking for on that post? I have phone rooted.
The AT&T Note 3 sm-n900a has a locked boot loader and can only run custom ROMs created from a stock Samsung lollipop ROM.
Update:
It was my understanding (perhaps wrong) that Safestrap was a way to work around the locked bootloader (ATT) The video on the main topic on this talks about a Verizon phone even though the topic is specific to the ATT note 3. Are they identical with regard to Safestrap etc?
As of now I have Safestrap installed and working. Boots with open lock/Custom on boot screen.
My confusion arises from conflicting videos at YouTube one suggesting Safestrap won't install a custom ROM followed by another that says it will?!?
If it won't exactly what is the purpose of even installing Safestrap if you are still stuck with the exact same android version and all the ATT bloat?
-edit-
FYI currently phone no SIM not provisioned but was used on ATT then switched T_Mobile service (consumer cellular so I can switch between those two. ATT and T-Mobile service suck here but at least with T-Mobile I have WiFi calling on my J2 which avoids poor signal issue at home. Hoping to move back to Note 3 if a good update can make it Wifi Calling enabled )
So far the only reply here has been to tell my my bootloader is locked. Since instructions include using Safestrap as a work around that really does not help me.
At the start the guide was to upgrade the phone to Android 7. Things seem to break down for my understanding of all this if the only work around is Safestrap and if that cannot install a custom ROM how do I get from here to 7/Nougat?
SIDE QUESTION but important.
Having downgraded from 5.0 to root device, I am not getting a request to accept update from ATT ( back to 5.0 I assume ) which I deferred for now. The question regarding this is, if I permit the ATT push back to 5.0 on my rooted device will I lose that root access and have to start all over again? (Darn I don't want that)
Sigh...so confused.
EDIT
I'm reposting an edit to last because I can't figure out how to get the edit/addition to appear. LOL

So the whole topic of upgrading Note 3 to V.7 is a dead end? I'm stuck with a phone downgraded to KitKat from 5.0 after having rooted etc? Will a custom ROM for lollipop let me delete bloat then upgrade to Nougat?
The whole topic of upgrade to v.7 for note 3 is confusing because after two days of reading and trying options I seem to get no where and cannot even find a definitive answer regarding actually upgrading this phone?
There are no nougat ROMs for the n900a.
Safestrap is only good for certain roms and twrp can't be installed on an n900a with a locked bootloader.
Useless phone?

Okay so I wish the whole topic on installing V7 on Note three just started saying if you have an ATT Note 3
READ NO MORE, all hope is lost!
I read numerous posts on numerous sites telling me I can upgrade this phone and none stated up front ( Does not apply to ATT versions ) leaving me to saving a text file full of instructions, links, a folder of downloaded files etc. all aimed at my N900 phone...none of which is valid.
I guess I will just restore to factory and sell in eBay if it is a useless phone other than to put on ATT or T Mobile as a plain old phone full of bloatware.
That or just load my music library on it and bluetooth it to my stereo as a juke box.
*sigh*

Actually I believe I posted this topic under the forum for the phone in question, Note 3? I was inquiring about the actual device not about ATT per-se.

As AT&T has a locked bootloader it has little relevance to Note 3 International model.

So if I obtain an international GSM version I should be able to update ROM?
I don't think the international version supports LTE in North America.
