Help me get a 900T3 back to stock - T-Mobile Samsung Galaxy S 5

I have taken my stock nandroid backup for granted and now more or less no longer have access to it, as it is sitting on an external hard drive thousands of miles away from me. I am beginning to regret that.
I need to get back to a "stock" state in order to do a SIM unlock. I put stock in quotes because am not exactly sure what that means as far as how far I need to go. Do I need to flash a stock recovery? Do I need to unroot? Can I just flash any stock ROM and have that be enough?
I have a 900T3 and am currently on the GPI1 firmware. I am aware of the sammobile firmware downloads page and am totally fine with flashing any of those. Although, I'm not sure if I need to manually update one by one, or if I can just flash the most recent one and be fine with skipping everything in between GPI1 and the most current.
Is there somewhere I can download stock ROMs specifically for the 900T3? Can I use stock ROMs for the 900T and have it work? What do I need to get a stock ROM to successfully boot? Matching firmware/ROM versions? Stock recovery? Just do a wipe and flash the ROM in twrp and I'm good to go?
Thanks

You can use the Latest Stock Rom Version, for me it was a 4.4.2 BNH5(worked best for me) for the G900T.
Backup all of your pictures etc first then use Recovery to wipe the phone and use ODIN to install the firmware.

Awesome. So I'm on GPI1, do you know if I can downgrade firmware from here, or can I only go forward? I did want to update anyway, can I flash to the most recent first or do I need to flash up to the most recent individually?

There's one newer than GPI1. Just download the image from sammobile and flash it from Odin. The phone will then be 100% stock.

It is a TMobile Phone- So you can upgrade or downgrade. ATT and Verizon are the only 2 I know of that Lock Their Bootloaders down to prevent downgrading.

[Q] Please help me get my head around rooting

Hi all,
Excuse the noobness but trying to get my head straight before I dive into rooting and flashing custom ROMS
I currently have a Telstra Australia S2 on kernel DVKF4. My aim is to root and flash Litening ROM
I think to flash Litening ROM I do not have to Root I can just go ahead and flash it however I would like to take a backup of my current firmware first, if I go ahead an install Litening my original Telstra will be gone and wont be able to back it up now?
If I understand this correctly I first need to root and I need to flash an insecure ROM. Now currently the DVKF4 insecure ROM hasnt been uploaded yet... Can I use any old kernel to get root access?
I know if I do this I will get the yellow warning label but will this even matter since after I gain root I am going to flash litening anyway so that will replace the kernel anyway with the litening one and I will not get the yellow warning. Correct?
Anyhoo I wanted to backup current Telstra firmware in case I need to flash it back for warranty. Also I would have to unroot it. So in order to do this I would firstly restore the backup made which would flash back the original telstra ROM but the phone will still be rooted?
Since I made the backup with the 'any old' kernel to get root does that when I restore I am going to have that kernel still on phone and giving me yellow warning?
OK so I would have to flash back the correct DVKF4 kernel to get rid of it again. So I would have to flash back the original (secure) kernel to get rid of this and user superoneclick to unroot and then its back to its original state? (besides the download counter of unsigned ROMS which can be reset with jig)
Also does the yellow warning come up even if you use an insecure kernel which is the same version your firmware needs?
I thought it's the kernel which gives the root access but it's not is it? It just allows superoneclick to install the superuser files etc?
Thanks!

True but you may find copy on Branded roms post dev section or use vanilla Samsung stock rom .
If I understand this correctly I first need to root and I need to flash an insecure ROM. Now currently the DVKF4 insecure ROM hasnt been uploaded yet... Can I use any old kernel to get root access?
Depends upon what the instructions say but generally as near to possible as your rom .
I know if I do this I will get the yellow warning label but will this even matter since after I gain root I am going to flash litening anyway so that will replace the kernel anyway with the litening one and I will not get the yellow warning. Correct?
Incorrect you will need the USB recovery jig to remove the warning and reset the custom rom counter to zero the easy way .
Anyhoo I wanted to backup current Telstra firmware in case I need to flash it back for warranty. Also I would have to unroot it. So in order to do this I would firstly restore the backup made which would flash back the original telstra ROM but the phone will still be rooted?
A backup via CWM of a phone will restore what you backup .
To restore unrooted you will need to save unrooted in the first instance .
Original rom or branded rom flashed via Odin will remove root .
I thought it's the kernel which gives the root access
Yes if you use the usual method no if you use another method .
Root & CWM kernel.

Hey thanks but how do I make a backup of the unrooted current carrier ROM? Don't I first need to gain root access to be able to run CWM and make the backup?
Or is there a way I can go into recovery now with the device currently unrooted and stock carrier ROM and make a backup?
Thanks

As was pointed out above by JJEgan, either wait for the Telstra carrier branded firmware to hit this thread.
Or you can try the root/unroot method as described here. Good luck

yeah thanks I get that part it's just that he mentioned if I want back a backup of an unrooted rom I need to make the backup while unrooted but I did not think this was possible since you need to root first before being able to backup?
Just after some clarification about that.. Thanks

[Q] I have an i9100 with MIUI installed. I would like to flash back to ICS. How?

I have a i9100 rooted CWM (forgot the kernel name) and MIUI installed. I would like to change to the most currect ICS available for it without using custom roms.
Selling to a friend who wants it more or less reverted to the manufacturer. I live in the US and I seem to need assistance with this as its been a while since I've done it.
I'd like to get the best kernel on there too and root after flashing back to ICS as well as keeping my contacts on my sd card.
Search for a stock ics firmware and flash it with Odin.
Here a post that may help you.
Is it just a matter of installing from the SD card like you normally would when flashing custom roms?
Would it lose the root?
Also, the post you mentioned doesnt have any american versions of the ROM. Would that matter? Im just wanting to make sure it will work with ATT and be in English
Here a thread with more information.
With Odin you must connect the phone to PC in download mode and yes, you will lose root flashing a stock firmware. After you can flash an insecure kernel (Chainfire's for example) and gain root again.
What do you mean by insecure Kernel?
And is it going to matter if I install the rom from a different country?

[Q] Trying to flash Alliance Rom

The first step for flashing Alliance was making sure i have the 4.3 firmware. Flashed via Odin.
I experfienced some trouble with a bootloop issue so i changed cables and then partitioned with the .pit file.
All's well now, it at least runs the stock firmware just fine. Now i'm strugglling with the most basic simple part IMO... how do i install the custom Rom without the recovery??

You are rooted still correct? Easiest way I guess is to just download Rom Manager or GooManager depending on using TWRP or CWM.

I chose to bump up my android version cuz i friend another SIM card. I tether for my Hulu, Netflix, Amazon Prime, and whatever else, thankfully my laptop can get weak unsecured internet signals, but i'm walking my Note around the apartment trying to get good 1x reception Problems may be overlapping but next step is something basic from the Play Store to verify root.
I read of some luck with root for 4.3, just not bootloader. Am i correct?

Not rooted. it sounds like rooting is still an option, just not custom recovery?
Is using ODIN to flash stock rooted an option? No valuable files on phone currently.
(Fortunately I'm at work right now so I have time to make well informed decisions. Thanks for your help)

I believe if you took/flashed the OTA update, your kinda out of luck and stuck now. I'm not 100% certain of this though but I think it probably relocked the bootloader and the only thing to do is wait for someone to root/unlock 4.3.

Correct. If you took the OTA it relocked your bootloader and you are stuck. You can still root the official 4.3 but you are stuck waiting until someone unlocks the bootloader. This means no custom ROMs/Recovery.
Which 4.3 firmware did you flash? If its the OTA then yes you're outta luck.
If you did follow the Alliance's rom thread. There is a 4.3 MJ9 firmware you need to flash. It doesn't have the locked bootloader. You are then able to boot up in the basic recovery and then flash either TWRP or CWM recovery.

Update to Lollipop or flash another rom?

I've been having some terribly sluggish issues lately. Lagging when I text, browse the web, even listen to music.
I honestly do not remember which method I used to root, but I rooted & kept the stock rom. I just deleted the bloat.
Not sure if this will help
http://i.imgur.com/L9prnWv.png
I'm at a point where the lagging is really irking me, but I'm not sure which route I should go.
Since I'm rooted, can I just go ahead with the OTA update without any issues? If so, is there a method to root on lollipop?
If not...Should I just go ahead and flash another rom?
Don't take the ota! Follow he thread about upgrading to 5.01 keeping root! Totally worth going to LP. The speed is great! Give it a shot.

Did that, and it says i'm still on 4.4.2. Very strange.
I'm still getting the pop up for the OTA
Make sure to back up any data and do a full wipe to nc5. That can make a difference. Or, Odin back to nc5, and use the Echoe ROM or the Super6 ROM, both of which are on Lollipop.

This is all foreign language to me
Sorry.
OK, get a program called odin. It is leaked Samsung software that allows to flash stock firmware on your phone. You have to flash the stock nc5 firmware with this and THEN continue the upgrade to lollipop
Laziness and not knowing much has lead me to not doing anything about the issue until now.
The phone gets slower by the day, so it's time for a change.
I'd like to flash this rom http://forum.xda-developers.com/showthread.php?t=2550770 but i'm not too sure if I can flash this via the stock recovery?
If not, how would I go about installing TWRP? I did try to search, but the page kept timing out.
DO NOT TRY TO INSTALL TWRP. YOU WILL BRICK. Thanks to Verizon, we have a locked bootloader, which means we only have Safestrap and Flashfire. SS is based off of TWRP, but is a really really really gimped version. Flashfire is an app that functions like a recovery.
You cannot install that ROM at all, because of this POS bootloader.
What you CAN DO, is install Roms such as Eclipse,Kitpop,Hyperdrive, and Stang's 5.0.1 ROM.
OR, you could do the OTA with root method.

Flashing question for my Sprint Note 3

I'm currently rooted on 4.3 MJ4. Yes I'm outdated and decided to finally update. I'm going to flash to stock 4.3 MJ4. My questions is, after I flash to stock 4.3 MJ4. Can I flash NC5 from MJ4? Or would I have to do it in these steps ( MJ4 then NAB then NC5? ).
Why not PH1? If you're wanting to stay with KK, NK4 is the last I believe. NH7 is the one most people used. Just trying to find out what you're trying to achieve
Also, if you're flashing a stock ROM, you don't need to first flash MJ4. Just flash what you want.

Awesome! Thanks! I am trying to flash a stock rom, but thought I would need to go in steps instead of instantly flashing to the most current version.
As for my plan: I'm rooted and on a custom rom. I want to go back to stock rom and then root again and flash to either cm12.1 or cm13. From what I've read, I cant flash to either cyanogenmod roms until I was on either lollipop or higher. I was also thinking, would it work if I was to flash a rooted current version of a stock rom, that way I don't have to flash a stock rom and break root and have to root it again?
For better results, I would flash a full PH1 rom and root, then install whatever rom you want. Usually they want the bootloader to be upgraded to lollipop and that really only happens when either flashing a full Odin rom or a bootloader image. Doing only the bootloader doesn't upgrade anything else and may cause issues.

What is the PH1 rom? I've already flashed to stock NC5 so far and lost root.
It's the latest rom. I don't think an Odin has been posted, but you can grab from the Samsung firmware site. Load that, then root by flashing TWRP and boot into recovery and flash SuperSU. Done.

EDIT: I went ahead and used the Full Restore. Fortunately, it did not WIPE any data. YEAH! And it looks like I am on my way to an updated NOTE3.
Hello. My Note3 is on 4.3. It was rooted a couple of years ago, but out of use since Oct 2015. I still want to use the Note3 for non-cell phone operations, browsing, camera, etc. I want to upgrade, but the OTA is locked out.
I am lost on all of the many, many posts on how to updated a rooted Note3, but most of them are outdated. I have it mostly backed up as far as handwritten notes, photos, etc. But I don't really want to have to start from scratch if I don't have to.
I am currently reviewing rwilco's one click options. There are two software packages listed in his directory. One of them is dated 02/27/15 and is called nodata restore. Will this keep from wiping the phone as opposed to the fullrestore exe posted 04/12/14 vs the tar posted 02/27/15.
I am not a complete dodo, but I am having a hard time getting this phone unrooted and updated.
Thanks for any detail instructions or links to the best way to update this as of 9/5/2016!!!
