I'm running this phone on the tmobile network after I downgraded from 4.3 to 4.1.1 to unlock the phone. That worked perfectly and I'm now in tmobile with LTE and everything. My question: if I upgrade back to 4.3 will that lock the phone once again? I wouldn't want to go through the process again if it meant I would be locked from using my phone. I ask because of security issues with 4.1.1

what's our newest firmware or bootloader? I'm seeing MJ5 in TMO Dev Threads for ROMs and to my understanding that was only for the international phone. I used to be able to flash all the i9505 ROMs but now with 4.3 I've been told not to. Data goes in and out unless you have MJ5 and I really want to run the i9505 4.3 ROMs. It even increases WiFi and data signals too significantly.
I think I have old software since I haven't updated bootloader or anything since march.
anyone care to share some light here?

MDL is the latest official firmware / bootloader for the T-Mobile S4.
MJ5 is indeed an International firmware, but as you said, data goes in and out when the phone goes to sleep.
Hello there, I wanted to know if there was a way to unlock the device without purchase on 4.3
thank you
If your phone is paid off and has been activated for at least 90 days, just walk into tmo and say hey give me my code.

does it matter if you're using a custom kernel or anything when using the code?

sim lock 4.3
You only have two options... Option 1, You wait until kikkat 4.4 become available for upgrade then unlock the phone with same code. Or option 2, you find the stock rom that came with the the phone which is the ice cream 4.04. Then use odin to downgrade and then you can use the same code.
From all my reading. I was under impression you cant down grade with odin?

You can't if your device has the official 4.3 update, like ota or if it was done through kies or Odin

Its possible it could've been broken by mistake, some people have had the same issues with Samsung devices on 4.3, try the new 4.3 update and see if it helps

If I switch to TMobile now will I still get the KitKat update from ATT when it is released? Using ATT Note 2 unlocked.

Negative..
The carrier dependent information will be different when using the ATT device on T-Mobile....
You'll need the MK7 modem to get the device working...along with the t-mobile sim card...
ATT will not recognize the device...g

I'm on t mobile now and did not change anything. Using the MK6 modem that came with the 4.3 ATT upgrade a while back.
Only functionality that I lost was hotspot that is blocked by some ATT system files.

No issues if you are on the tmo network...
Many users have ATT devices using mk7 modems for tmo...
It's the only way to get full device function...
But if an ATT modem is working fine for you...there is no problem leaving it if you prefer...g

I see. I'm gonna give it a try then. Always been hesitant due to all the warnings about bootloops from @Bajanman and others...

Flashed mk7. No signal. Baseband unknown. That sucks
Back to mk6 and no LTE.

I have never ported the roms... I do think if you use any of my roms or from other dev it should just work without any issues, all u need to do is just check ur apn settings to make sure everything is correct so u can get data and mms working. so just make a backup first, then flash the rom..

The problem is I like the t mobile roms. But they won't work on the at&t n3. Because of the locked bootloader and kernel. Otherwise I can just flash it without any issues.

SafeStrap only for your ATT device. Even if you port over successful, you will always have a locked bootloader. Sorry

How about if I change the bootloader and kernel in the rom to the nc2 at&t version. Do you think that might work and I will get a fully functioning port?
