[Q] Flashing i9505 ROM + Modem on SGH-i337?

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.

[Q] Can't Find Stock Firmware GTI9500

Hello, im trying to unroot my phone and return it to stock firmware to update it to 4.3, ofc then ill have to root it again, the basic need for me to update is that im trying to install my apps on sd card, which firmware 4.2.2 that i have does not allow. But i cant find my stock firmware on the websites, the version i got is I9500XXUAMDK. Bought my S4 in Saudi arabia, so anyone has a link to that firmware? or should i flash an updated firmware directly? im trying to unroot guide over here http://forum.xda-developers.com/showthread.php?t=2265477 so what exactly should i do? e.e
Note: does the 4.2.3 update have options to install to SD? if it does i pretty much prefer it to 4.3 since i hear it has some problems.
HERE we go. You only have to flash this firmware for unroot it if this is the correct firmware for ur phone
thanks! But a question arises xD is this 4.2.2 or 4.2.3 or 4.3?

[Q] Updating my I337 to 4.4.2 with I337m ROM?

Hello,
I have a rooted AT&T i337, build number JDQ39.I337UCUAMDL -- I no longer want to get OTA updates to keep my root, and I am spending most of my time in Canada now, so I am wondering if I can flash the I337m ROM I got from samsung-updates? I am getting conflicting info -- I know i337 with later updates have locked bootloader and flashing the ROM doesn't work, but what about my already rooted phone?
Thanks,
Adrian

[Q] Rogers GS4 4.4.2 NE1 Custom Recovery?

Hello, I have a Rogers Canada SGH-I337M rooted running 4.4.2 I337MVLUFNE1 and I would like to try custom roms on my phone but I have never tried doing this before and I don't know what custom recovery I can use with this baseband version. I was going to try Safestrap but the versions for it that I saw on its XDA page were for NB1, MK2, and MF3 baseband versions. Will the latest version of Safestrap be compatible with my phone, or will I need to downgrade/upgrade my android version to get a different baseband version? If I will need to do so, would I need to unroot or make changes before changing the android version? Help would be greatly appreciated.

Safestrap is primarily for the phones with a locked bootloader because we are not able to flash any other type of recovery. Since your bootloader is not locked, you should use philz touch or TWRP. That way you'll be able to flash kernels, as well.
Best advice I can give you is to read before flashing anything that way you know what you are getting yourself into. Since you are i337M, I would start with this thread... http://forum.xda-developers.com/showthread.php?t=2314494

Okay, thank you very much for clarifying that my phone's bootloader was not actually locked, I just assumed it was because I couldn't find anyone else with that baseband version. I have also read the thread you linked, I am going to try TWRP.

will i lose any data?
and what about the stock recovery?
thanks for your help
My Recommendation for you in this case
Go to 4.3.
4.4.2 is Very Buggy and will mess up your phone!
