nope, there is none so far for 4.4.2 for any variants

Hi folks, I'm thinking about getting the SGH-I337 (AT&T version of the s4) which from what I've heard is identical to the i9505 but flashed with a different Modem and ROM. What I was wondering was if it was possible to flash the i9505 ROM + Modem onto the SGH-I337 and essentially "convert" it to the i9505. I was wondering if anyone had more details on the hardware and if there were any issues that I'm just not seeing. I see that the ROM is not an issue. More curious about the Modem. I would like to use the phone on LTE in the UK
I'm looking for a 32GB version of the i9505 and so far, the only option I have is the SGH-I337.
Any thoughts?

Yes you can flash i9505 rom but not sure if you can flash i9505 modem. The way everybody is doing it, to insure ATT network compatibility, is to flash just the i9505 rom while keeping the ATT radio. By doing so, your device ID will switch to GT-I9505 and the SGH-I337 will be gone.
So from what I'm understanding he can flash the i9505 ROM which by he means stock firmware? So I can flash i9505 5.0.1 lollipop stock firmware on my i337? That's what I understood. Is it true?
The bootloader on the i337 may be locked so flashing the i9505 stock firmware onto the i337 may not be possible. I am just guessing here as I have the i337m which does not have a locked bootloader.

Mine is not locked, I bought it used and it was rooted already, so I installed twrp through flashify and I am using cm12. The reason I'm asking is because in sammobile there isn't any lollipop not even kitkat firmwares for my i337 model. So I wanted to know if flashing the i9505 kitkat/lollipop stock firmware on my device could be fine. If not, I can keep on using cm12.
Att never released a complete kk or LP rom. These were only available via ota updates which explains why they cannot be found on sammobile.com.

How could I update it then? I'll be stock in jellybean 4.2.2 because with no root I never received the ota update nor for kikat and not even lollipop.
The rom must be running a completely stock 4.2.2 rom, including stock recovery with no root, to install ota updates.
You could look in the general or development forum to see if anyone has made a flashable zip for the ota updates. The again, the ota updates may not work without an updated bootloader and modem which may mean locking the bootloader.
Hey all, I'd like to install this rom, but my phone (S4 international GT-i9505) is KN0X tripped on 4.3. I currently run 4.3 stock. Is it safe to install this rom, and is it possible to downgrade back to 4.3 stock after?

Yup you can flash any custom rom via custom recovery and Yes you can still downgrade your phone into 4.3 stock rom but remember not to flash a Stock 4.4.2 Kitkat firmware because flashing 4.4.2 firmware can no longer downgrade to 4.3 stock rom. Flashing any custom rom/root will trigger your knox and If you wanna know more about knox , check this thread Have a nice day.
Basically, I lost my root when updating to Lollipop GPE on my regular S4. I didn't realize this before I deleted my backup (stupid idea I know).
I did find this (http://forum.xda-developers.com/showthread.php?t=2794879) which, from what I assume, I can just install and my phone will go back to 4.4.4 rooted but here is my problem. Since I installed Lollipop GPE rom on my phone the model number is now I9505G even though I originally didn't buy that version of my phone, so do I flash the I9505G rom (GPE) or the regular I9505?
If it helps, I'm with bell in Canada and I was installing jfltecan roms before this all occured.

Jfltecan is refered to the model: SGH-i337M. Try to reflash the stock ROM for your model via ODIN.
Hi,
As the topic suggests, I am going to buy a used S4. I checked two S4's both with stock recovery, one was on lollipop 5.0.1 and the other was on kitkat 4.4.2. The stock recovery of 5.0.1 was showing more options than the one on 4.4.2. Is it some thing implemented in the new lollipop 5.0.1 upgrade ?

It could be that samsung added more features in the new recovery. With every update, there comes a new recovery, bootloader etc. so this case is very likely.
If you are going to install a custom recovery anyway, then that doesn't really matter to you
Can a Loki Patched AT&T S4 can go to Lolipop? I have a feeling that something special needs to be done so that the old 4.2.2 bootloader is compatible like how there was a specific patch for 4.4.2 . I would like to run an international Lolipop i9505 ROM on my S4. I'm still on a custom 4.4.2 ROM and didn't know that there was even official lolipop ROMs. Thanks guys.

For sure. I'm on Loki and using CM 12.1 with my AMDL bootloader.
