[Q] Can't flash stock

Hi,
Recently, a relative of mine purchased an Unlocked AT&T S4 from a local shop here in Canada. I found a bunch of bloatware from AT&T and some of the settings on the AT&T are different from what I have here on Rogers. Since he has the SGH-i337, I figured I can flash the Rogers SGH-i337M ROM no problem. I attempted to do through Odin, but I keep getting this message on the phone:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
and I get this message on the computer:
What can I do so I can get the Rogers ROM onto his phone?
Android Version: 4.3
Baseband version: I337UCUEMK2
Build number: JSS15J.I337UCUEMK2
Thanks

Even though you live in Canada still doesn't mean anything even if you get it to “unlocked" because unlock means SIM UNLOCK. He has the i337 “at&t US version" Only the i337m “canadian variant" will only be able to flash Canadian ROMs unless he has the phone on MDL baseband or a Google edition phone. The boot loader is locked on the i337 so there is no way you can flash anything besides the stock Rom that comes with it... However if he's on MDL baseband he can flash most whatever he likes if it is mf3-mk2 you need to look into safestrap. Do more reading and researching before your friends phone turns into a paperweight.

8-15-2014 New system update for Samsung Galaxy S4

I am running 4.4.2 on SPHL-720 (Samsung galaxy S4 (sprint) and just received a notice that a system update has been downloaded. I have not installed it yet. Could this be the 4.4.3 update?

I think it's NG2 modem update

I'm running sacs older version 4.4.2 version 2 I think with the nae modem. Has anyone tried the update? Will this break root? What's the benefits? I've searched and found nothing.

Look like I lost root. I need to re root my phone. If anyone has idea let me know

I found the downloaded zip on my phone and it is the NGA update. However it will not install on my rooted NAE phone. The recovery mode install fails.

A) You cannot accept an OTA while rooted. It will not install unless your device is bone stock.
B) Please learn to use the search function. This update has been out for over 2 weeks and there are 4 threads on it that will answer any questions you may have about it.

[Q] Root for lollipop

I haven't used my S4 in a while since i got my S6 Edge i was wondering is there a root for the S4 5.0 I've been looking everywhere and no luck yet

I'm seconding this question.
In addition I'm on 4.3 and my system can't even manually pick up on the update. What's up with that?

Third that...
I just got my S4 L720 replacement, came pre-loaded with 5.01 and I can't find a way to root it, cant do anything with it really...
Haaaaallp!

Just use Odin to flash TWRP, then in TWRP flash Chainfire's SuperSU.

It's the same as KitKat, what mattzeller said or Odin CF-AUTO-ROOT by Chainfire

Ok I'm not an expert at all and I don't want to follow the wrong guide and mess everything up. I googled some of the terms and I don't feel confident enough in what I found.
How exactly do I get to KitKat (be it the stock rom or the one really close to it) and root it?

you might have the new version, the L720T. root method could be different?

Straight-forward way to root i337 Android 5.0.1

I've been searching for a way to root my SGH i337 phone on Android 5.0.1.
I found threads that say to "Downgrade" or "Flash NB1". Then i went searching on how to do either of those things and all i get is downloads to dead links.
Nothing straight-forward that is actually going to help me root my phone. I haven't been able to find a simple guide on doing this could someone point me in the right direction? I'm ****ing frustrated.

I found this in the upgrade to 5.0.1 and keep root thread but have not tried it as I am traveling. I intend to look deeper into it when I get home.

I took the plunge and installed the deskop version of KingRoot and it worked perfectly. Did take a couple of minutes and I had to do some investigative work to get around the Chinese UI.
Here are some notes I put together for the AT&T S4 (I337) with OC4 (should also work on OC3): http://forum.xda-developers.com/showpost.php?p=62378222&postcount=20

How can I Network unlock S4 I337 lollipop

Hello,
Please I need help unlocking AT&T Samsung s4 i337 on Android 5.0 lollipop.
I read about Region Lock Away but it requires root and unable to find a possible rooting guide because it's Android 5 lollipop and locked bootloader prevents me from installing custom recovery
Please I need guidance if I should downgrade the Android version. Which one will be preferable that supports rooting and Sim/network unlock.
Thanks for your favorable response

I recommend contacting AT&T to see if they will provide the unlock code for free. If not, look on eBay for an AT&T unlocker.

Well I finally unlocked the phone
- I downgraded to android stock 4.4.2 using odin
- Rooted the phone with towelroot
- Installed safestrap Recovery
- Flashed baseband to MF3 using safestrap
- Unlocked network with RegionLockAway
- Unlocked Tethering & Hotspot with Xposed Installer
Though I did not try going back to lollipop. I am quite satisfied now.
