I understand rooting and installing custom ROMs, as well as using ODIN to flash back to stock firmware, but I just want to double check something.
My mom has an unrooted, Canadian G7-L03. She would like something at least 5.0, but Wind and Videotron don't offer anything beyond 4.4.4.
But on the American website, they offer 5.1.1 and 6.0.0. Is it as simple as flashing the new ROM with ODIN? Or do I need to root first? Will it network lock the phone?
How do I know if it's compatible? Everything I see online seems to say that it is exactly the same (I think?).
if its from videotron you can use this guide to upgrade http://ministryofsolutions.com/2016...date-to-marshmallow-canada-latin-america.html
If its from Wind, don't even try to touch it

Hi I have been on this site quite a few times but this is the first time posting. I rooted my s5 using towelroot and everything is working fine but I would like to install cwm recovery. Before I do though I want to make sure I can get back to stock with no issues. I am looking for a unbranded stock firmware for the t-mobile s5. It is currently unlocked and has never been on tmobile. I am currently with net10 which uses the att network. I just don't want to flash tmobiles firmware as I am not on tmobile and don't want all the bloatware. Is there a unbranded stock firmware for the 900T variant? or maybe a way to download the stock recovery at least. I know I can backup my current rom but I dont think that includes the recovery. Thanks in advance.

If you root it first i think Flashify from Play can backup and restore your current kernel and recovery. But first check if Flashify supports the 900T.
BTW the G900T rom G900TUVU1BNG4 is available on Sammobile.com to flash with Odin, you can always debloat/freeze apps/widgets you don`t need.
I found a site with all the firmwares.

NEED HELP Factory Unlocked S5 Firmware SOLVED
Thanks for all the help guys Flashify worked for me perfectly. I needed to backup my stock rom because as I stated before I have a unbranded phone. It is the t-mobile version but if I put the tmobile rom on there I end up with bloatware and whatever else. So I was able to flash cwm recovery and make a backup of my stock rom to my sdcard. Thanks again
I am currently running 4.4.4 on a G900V wit NK2 rooted and Saftestrap. The phone constantly nags me about updating.
My predicament is that I use T-Mobile as my carrier and at the moment everything works except wifi calling. I can run a stock TMO ROM and get everything working great - but then I think I will be stuck at Kit Kat, and cannot use custom ROMs.
I am wondering what my options are with the update. I have heard I can roll back to 4.x but what if the radios don't match my stock TMO ROM anymore?
Will OTA update un-root my phone and hose my ability to use it with T-Mobile?
Help please.
I think I found my own answer on this thread, 3rd page:
http://forum.xda-developers.com/verizon-galaxy-s5/general/success-g900f-rom-g900v-s5-t2839557/page3
I currently have AT&T stock (I used to have a custom ROM then had to flash to stock ROM to be able to flash to another custom ROM--however, I accidentally flashed a newer version of the AT&T stock ROM which locked my bootloader and I could no longer flash to a custom ROM). I updated my AT&T stock ROM recently and now my back/menu buttons don't work, so I want to see if I can flash to a custom ROM now.
I don't remember the procedure to flash a custom ROM--do I first need to get root in order to unlock the bootloader to be able to flash ROMs (i.e. if I have root then I am guaranteed to be able to unlock bootloader in order to flash ROM)? Is the baseband version the only thing that determines whether I can unlock the bootloader and then be able to flash ROMs?
I currently have OK2 as broadband version and checked one of the stickied threads which said this:
" ROOT
OK2 -- No direct root method. Must Odin OC4 kernel, use Kingroot, then Odin OK2 kernel back."
Does that mean what I have to do is use Odin to get OC4 kernel, then use Kingroot, then Odin OK2 kernel and then I will be able to have root, which means I can then unlock my bootloader and be able to flash to ANY ROM (not just TouchWiz-based ROMs)? Is there anything else I need to consider or is this 100% foolproof? In the future, what should I be careful of in order to prevent getting my bootloader locked again--just that I don't flash a stock (AT&T) ROM that is known to lock back the bootloader?
Thank you all!
There's no way to unlock the bootloader if you have updated your device to the lastest firmware version. The only thing you can do is flash SafeStrap and use Stock Kernel Based ROMs which are compatible with Safestrap.
As regards to the procedure of rooting an OK2 firmware, I'm afraid I won't be able to help you.
Have a happy new year.

I was just about to sit down and flash a stock ROM. Can you explain what you mean by this? Did you flash OK2 and it caused you a problem?

It was a while ago but I used to have I believe an MDL broadband version which meant I could flash any ROM available. I tried a different ROM, didn't like it, then decided to flash back to the stock ROM but accidentally flashed a newer version of it, which meant that my bootloader is now locked. With a locked bootloader, apparently I can only flash to a newer stock ROM (not other ROMs like Cyanogenmod) via Safestrap.
I think if you don't have the MDL broadband version you shouldn't worry about it anyway because it is locked and you will only be limited to flashing stock ROMs.
Slight correction
The previous entry is not entirely correct. Like the OP, I was originally on an unlocked bootloader on my i337. I'd purchased my i337 on the first day and eschewed OTA updates. I wanted to try a touchwiz based ROM, Hyperdrive, and in doing so I recall flashing the stock NB1 firmware. Every firmware beginning with NB1 has a locked bootloader and there has been no progress for more than a year in unlocking the bootloader again. This can limit you to either stock ROMs OR other touchwiz based ROMs like Hyperdrive. I love the Hyperdrive ROM (now on release 21) but its developer has moved on to a newer phone, so it's stuck at Android 4.4.2 and no one has picked up the project in many months. There are several other touchwiz based ROMs for the i337 version of the S4 which I have also tried but I prefer Hyperdrive's myriad customization, even without proper patching. I'll be moving on soon to the Nexus 6P as my daily driver, but would very much like to keep my S4 up to date with a custom ROM. Given the number of people that have been in this same situation, where a newer stock ROM from AT&T locked a previously unlocked bootloader, it's been surprising that the issues have not been overcome on a phone as popular as the Galaxy S4 was and continues to be. I've seen unlocked versions of the S4 selling for just under $400 in the last week of 2015.
Use the desktop version of Kingoroot to root and use Super su and update the binary. Don't forget to hit thanks if this helped.
The bootloader for the at&t s4 was never unlocked. The MDL bootloader had a flaw in it that allowed you to use LOKI which is a lock bypass, not a way to unlock the bootloader.
hi
i purchased a unlocked at&t phone off ebay and it works fine but its on 4.4.2. i want to root and install new custom firmware based on the S6/7 rom - newest android basically that'll work.
What rooting guide should i use and whats the best rom to get it flashed to a UK based rom?
If you are on 4.4.2, do NOT take the OTA update. updating to the official AT&T Lollipop gets you an encrypted bootloader that is unlockable.
look for guides based on 4.4.2. you'll want to install a recovery, then you can flash custom roms.
Hello
My LG V10 came across the famous bootloop issue, and I shipped it to LG. In the meantime, I am using an old S4 that was saved for emergencies like this one. It is running 4.4.4, I337UCUFNJ4, and I rooted it with Kingoroot.
I understand that it should OTA to 5.1 in pronably a day or 2 if I check for a software update; it sat turned off since 2014, so it did not receive anything.
1. Do I OTA and reroot?
2. Can I manually jump to 5.1?
Ultimately, I would like to install TWRP and the Blissrom or some other ROM, but I don't want to take an OTA that may screw me up for later. I read that there's a loki thing that will prevent future installations of recovery or something like that. I realize that I will be using a short time (2-3 weeks), but I would like to leave it rooted and with a good ROM.
Thank you
The bootloader is locked so that means TWRP cannot be flashed to the phone and the phone will only run custom ROMs based off a stock Samsung ROM.
OTA updates will not work if the phone is rooted.

I'm confused or perhaps you are misinformed. I have seen a lot of ROMs for this device including Blissrom and many others. All od them get flashed through twrp or Safeway or aome name like that.
You mean safestrap?
Maybe you are thinking of the non-AT&T models of the s4 that work with custom ROMs such as Lineage and Validus. Only the AT&T version of the s4 has a locked bootloader, starting with Android 4.3 and up.
There has never been an sgh-i337 s4 with a locked bootloader than can run TWRP. Same goes for the AT&T sm-n900a note 3 with a locked bootloader.

But there's a forum dedicated to AT&T development full of roms here on xda.
Yes, there is a full section but you need to look at the ROM requirements. Some of these ROMs were developed before AT&T pushed out an OTA update that locked the bootloader. Other ROMs are made for the non-AT&T s4 such as the sgh-i337m and gt-i9505.
You will not see any ROM that is not based off a stock Samsung ROM that can be installed onto an AT&T s4 that has a locked bootloader. Also, you will not see any version of TWRP/CWM/Philz that can be installed onto an AT&T s4 that has a locked bootloader. Same goes for the AT&T sm-n900a.
I understand your skepticism and appreciate your posts as we are all here to learn from each other.

Thanks for the clarification. So how do I know if my bootloader is locked? If I took that ota update that messed things up?
The bootloader becomes locked when the phone is updated to Android 4.3 or newer. I think it needs to be on the MDL bootloader to be unlocked. Anything beginning with an "N" or "O" means that the bootloader is locked.
Thanks audit. And I assume that there's no way to go backwards to a pre-4.3 rom and unlock that bootloader.
So. I'm on 4.44 rooted. Do i remove root and take any ota and reroot? I guess that I'll settle for going as high as possible with the stock rom but rooted with the ability to disable some of the bloatware.
How can I proceed?
In those links that you mentioned, it states that we can flash debloated TouchWiz roms that might be better than stock. Is that right? So can I do that?
You will need to install safestrap to flash a custom ROM. The debloated ROMs must be based off a ROM that is designed for the AT&T s4.
I recommend reading through this thread: https://forum.xda-developers.com/showthread.php?t=2616221
Audit... I odined back to nb1, rooted, and used flashify to get to rooted stock oc3.
How can I get to ok3? And should I leave ota services frozen so as to not ruin and loose root?
OTA will not work with a rooted phone.
Maybe this will help: https://forum.xda-developers.com/showpost.php?p=56453108&postcount=2
I don't have an sgh-i337 so I can't tell you how to get back to a completely stock ROM to get OTA updates. I have the sgh-i337m which is the Canadian version of the s4 without a locked bootloader.
I wrote a guide and FAQ revolving around the MDL bootloader here (if anyone cares to read it):
