Hi all!
My mother has a I337M Galaxy S4 from Telus. Purchased on October, 24th, 2013. This phone was manufactured before the July Knox upgrade. Contains 0% Knox and 4.2.2.
My question: Is there a way to upgrade to 4.4 without upgrading the bootloader. I have a SM-N900W8 myself and used the leaked Tecel version which worked fine (4.4.2). Does a similar process exist for the S4? She would prefer stock if possible.
Thanks

If you are on a non knox 4.2 just root and flash recovery for your model "M" shouldn't be that hard.

http://forum.xda-developers.com/showthread.php?t=2283918
So, after that, I gonna do set up CWM nandroid back up?
What about Bootloader? I have experience on previous device, Verizon Samsung Galaxy s3 unlocked bootloader.
Then install At&t roms only?

It has a locked bootloader
Also, you are lucky to still be on MDL firmware, DO NOT update to the MF3 firmware or you will lose ability to root your S4. My advice would be to remove sim card and turn off Wifi (to prevent accidentally updating) then root phone with Motochopper. Once rooted go freeze the update apks to ensure it does not update on you later. MF3 is unrootable as of now so DO NOT update if you want root!
I think you mean MF3. And yes, you have a locked bootloader, you should use this...and he is right do NOT do a update, once you do you lose root, and there is no way back just yet.

If you don't use the 4G make sure you have it unpicked. After upgrade some basic setting change as I have noticed
Help me!!! I need to Know, How do can i Downgrade from Android 4.3 to 4.1.2?
Why would you want to downgrade? The Galaxy S4 shipped with Android 4.2.2 so in terms of stock ROMs there's no way of getting 4.1.2 not sure about custom ones.

I'm pretty sure you can't downgrade to official 4.1.2 cause of knox bootloader. Besides I don't think S4 ever had 4.1.2 anyway.

Hi,
My S4 was rooted using vroot. I've disabled the updates so it's still on 4.3 MK2.
Is there a safe process to upgrade to the latest 4.4.2? Any way to keep root or re-root?
Thanks
I haven't tried this but I read it with interest yesterday

Can't find AT&T 4.4 at http://www.sammobile.com/firmwares/
I thought the news said it's released. Is that true?
Thanks
I don't know. I'm in the UK so I don't see that news

Hi, okay, so I've had my phone rooted for awhile.
I have a At&t Samsung Galaxy S4 sgh-i337mf3.
I've been using a minimalist rom given by someone on xda.
I love it, but now I'm thinking, is there something better.
1. Can I flash roms above 4.2.2 (i.e. 4.3, 4.4.2)
2. Would I have to update my phone using some odd technique?
3. What technique would you recommend for my build?
4. What rom would you recommend for my build?
Any help would be appreciated.
"mfc" ??
wow
MF3... I'm sorry... lol

To flash 4.4.2 roms you're going to have to upgrade the firmware and use safestrap. Read through this http://forum.xda-developers.com/showthread.php?p=49562527
