Easy root strategy available yet for l720t on OF1 - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I have a Sprint S4 L720t on Lollipop build OF1. I have tried Kingroot 3.0, and the newest Kingroot from the website with no success. I have Google this problem many times over the last few months with nothing but old strategies that no longer work coming up as results. Has ANYONE successfully rooted the sprint model, on lollipop, and could you please post this strategy here, or link me to instructions on how to do it? Any method will suffice as I am getting desperate. And FYI there is no way to downgrade to Kitkat once you take the OTA update, becausee even Odin with a stock kitkat rom will "fail". Please help. Also note that the l720t has a locked bootloader I believe.
Thanks

No, it is not locked, only AT&T and Verizon do that. The bootloader does prevent you from downgrading firmware (Knox). Two choices: Odin TWRP and flash SuperSU or Odin CF Auto Root. Birth are by Chainfire.

Good To Go
Being scared doesnt get me anywhere... so i took you advice...
I downloaded the newest twrp for my device that could be flashed with ODIN (2.8.4.0)
and the newest SuperSU (Beta 2.49)
Copied SuperSU to my SDcard... Flashed the TWRP with Odin... Booted to TWRP and installed the SuperSU, then did a factory reset, and VOILA ... Rooted l720t on OF1 firmware... Thanks for the help bro!

Urgent! Phone wont flash update

IM IN THE DEEP ****, AND I NEED SOME MAJOR HELP.
So I was trying to flash the stock ROM back onto my phone so I can send it back to Optus (due to ending my contract) and it won't flash! it gets to about "aboot.mbn" in the message box then fails every time. Tried two different stock ROM's! When it fails it shows "Fail (Auth)" for both stock ROM's. (One is the OPS, Optus xxuemk9 ROM I'm meant to have and the other some arabic region I accidentally downloaded..)
I've got the following setting selected on odin: Auto Boot, F. Restart Time. I'm going through PDA as you're meant to...
When I turn off my phone and turn it back on it goes "Update encountered a problem please select recovery through kies" or something, but I don't trust plugging it into kies...
Please help? I have no idea what's happened or what to do, it's flashed stock ROM's perfectly not even a few days ago.
I even tried adding the PIT file to re-partition but that didn't work..

EDIT:
I tried recovering through KIES but it says the GT-I9505 does not support it?!? And the phone won't connect to KIES to emergency recover any other way! And ODIN won't flash anything on it because it keeps coming up 'FAILED'
Am I screwed or am I screwed??
You can't flash a 4.3 firmware when you already flashed 4.4.2.
You need a 4.4.2 firmware.

Okay.. So flashing any 4.4.2 rom will fix it?
What's weird is I had CM 11 KitKat on it and then flashed the 4.3 stock ROM fine (but for the wrong region) a few days ago?.

That's something completely different.
If you had a 4.4.2 stock rom then you can't revert to a stock rom lower then 4.4.2.
Read the knox thread if you want to know more about it.

That's because it's referred to just by OA3. Why does he need a modem?

Here are the stock ROMs- http://forum.xda-developers.com/showthread.php?p=59310363
I would try www.sammobile.com for the firmware. I downloaded it from there before I had to return mine.

Get latest update to my rooted i337ucuamdl with 4.2.2

Hello!
I have AT&T (i337ucuamdl) Samsung Galaxy S4 with 4.2.2 installed. I have rooted the phone years ago and have not touched since. How do I update the phone to the latest 5.XX version? Is it possible to preserve the root? I saw the warning about MDL version that it is not supported. Anyone?
Thank you!
Look here.
Will I be able to use OTA updates with this ROM?
Thank you!

If you really still have the mdl bootloader, then you don't want to do an ota update, which will replace the exploitable mdl bootloader with a locked one.
If you have already done ota updates on the phone in the past, then you are already on a locked bootloader, and the above link would be irrelevant.
How did you get 4.2.2 onto the phone without replacing the UCUAMDL bootloader?

This is what I have now. Interesting that some applications are saying the phone is not rooted. I have done it 2 years ago. I cannot recall how I did it.
Thank you!
The application tells me I am not rooted.
I guess it is better to repeat the root procedure now.

This will root and install TWRP on MDL.
http://forum.xda-developers.com/showthread.php?t=2297900
This will give you stock OC3 lollipop and keep your MDL bootloader.

I have rooted the phone successfully yesterday. I got a problem during my backup with FlashFire. Apparently something happened during backup and my microSD card got locked. What ever I do now I cannot format it or write anything on it. Anyone experienced it?
Thank you!
Yeah. I had 2 go bad on me out of the blue. Thankfully, they were SanDisk, which has a lifetime guarantee.
Snapping along on stock rooted 0C4 I337, wishing for some good up to date lollipop ROM's to throw into flashfire
Installed OC3. Do you know if the OC4 is available? It fixes the security bug that I would like to use.
Thank you!

Need help rooting STOCK Verizon 6.0.1

Hi everyone,
I recently updated my phone about a week ago to the latest Verizon update.
I am now running Android 6.0.1 with Baseband G900VVRU2DPF4.
I'd like to ROOT my phone and run a custom debloated ROM but I'm not sure where to start as the guides have me somewhat confused.
I started with THIS link but it clearly states at the top that I need to be rooted which I don't have on my phone, should I still use the guide?
Also many guides are written for G900VVRU2BPB1 and I'm on PF4, is this a cause for concern?
Sorry for the questions but I'm inundated with questions and guides and I'm really confused no where to start.

I was in your position a couple days ago and couldn't find a way to root, so I flashed PB1 and rooted. You can download emcc brick bug app to see if you have a 15xxx.... or 11xxx... chip. If it's 15 you can flash PB1 and root, then unlock the bootloader. From there you can either upgrade to 6.0.1 or you will have a lot more custom roms available to you since many won't work with locked bootloaders.

I am trying to help my friend root his Samsung Galaxy S5, he has the exact same specs as the OP, and we also did the eMCC Brickbug check and he does have a 15xxx..... chip.
Could you provide a link to the how-to (if one exist) on how to get him from PF4 to PB1 so we can root?
Thank you.
Odin back to PB1.

How Do You Find Bootloader Version?

How do you check to see what version bootloader you have? I have unlocked my bootloader on my Note 3 and am running OF1/5.0. Ready to install TWRP and new ROM. But, not sure if I have a 4.3 or 4.4 bootloader and can't seem to find a simple answer and how to confirm.

This is what you'll get... In my case.. NC4 bootloader (unlocked) and OF1 based OS (Jasmine ROM)

Thank you for the recommendation. I dig the app, though I still don't know which bootloader I have going by the 4.3/4.4 scale. I'm assuming by now I have the most current one, which ever one that is, because I installed the latest TWRP and am running CM13 with no issues thus far.

The last 3 digits represent the OS/bootloader/firmware versions. In my case, bootloader is NC4 which is 4.4.2, my baseband (modem) is NK1 which is 4.4.4 and the ROM base is OF1 which is 5.0
