Hello,
Is it possible to downgrade the canadian edition of S4 i337M to I337MVLUAMDJ firmware?
Anyone tried it or is it a qfuse blown like ATT S4 after the latest update?
Thanks.
...bump. Anyone attempted this?
another bump... to keep this thread alive. Anyone attempted this yet?

I have downgraded from MG1 to MDJ.
Thank you Tronac for replying!
May I ask, did you downgrade to try SIM unlocking the free way?
According to http://forum.xda-developers.com/showthread.php?t=2285431&page=41, it's hit and miss.
How did downgrading affect your KNOX counter?
Again, thanks for your reply.

Hey guys, sorry i'm asking but i've searched and i cant find a certain answer.
Well, i want to update my i337M S4, to Kitkat from 4.3 official telcel/mexico firmware. And i don't know if knox will be tripped if i flash the official rom from canada with odin. Some threads says: "yes" and others "no". Anyone can help me a little please?
If you flash the ROM I believe it's a no but if you completely go to stock (and use Odin and unroot) it's a yes. Why do you want KitKat?

Because I dont want to wait the damn firmware roll from telcel, its crap :/. And the 4.3 is full of bloatware from telcel. I'm not rooted at all, i just want to "upgrade" the fw. And thank you for helping me
Help please :'(

If you're worried about tripping Knox I'd wait. But if you can live with that then the other firmware will probably work but it will come with it's own carrier crap.

I just bought this Galaxy S4 from someone but the thing is i use MetroPCS and when i insert the SIM card it asks for a pin number. Does anyone know how to unlock it. I understand i might have to root and downgrade but im a noob. Thanks in advance!!!

Do the downgrade and root, and while on MK2 use the "Possible SIM unlock for MK2" thread.

To go from 4.4.2 to 4.3 is somewhat possible, other downgrades aren't possible. There's a thread titled NB1 DOWNGRADE with the information to do that. Check your baseband first, if you're on NC1 you might need to flash NB1 first.

Is there any way to verify bootloader lock status?
Is maybe a noob question but I has been searching for a method to verify and didn't found any.
My device is i337m with ne1 bootloader.

I337m is not locked and won't be. All you have to worry about is Knox, and if you don't mind warranty void then it's not an issue.

I have a I337 too, but is still running stock 4.2.2 (mdl). Is it unlocked too? Or how can I know?
Thanks:highfive:

It is not unlocked. But there is an exploit, Loki, that gets around the locked bootloader. This only works on mdl firmware and does not work on newer versions.

I've heard mixed results. Some threads say I could kinda do it and some threads say I can't. Safestrap only.
Anyone have experience on 4.3 that could help me out?
I think it depends on the bootloader version of the phone as to whether it is or is not locked.
I don't have the i337 as I have an i337m but this thread may help: http://forum.xda-developers.com/showthread.php?t=2616221
Do you have an ATT phone? If so, you're fukt like me. Yeah, we can only do Safestrap. I'm on 4.4 and it's sgh-i337
Me? I have an i337m.
I know where to get MD5s I can dowload with Odin to restore the stock firmware, and I was wondering if flashing a 4.2.2 over 4.4.2 would be possible to allow bootloader unlock. I'd really appreciate a quick response, because I planned on returning it soon! Thanks in advance to anyone who replies!

Once you have updated past 4.2.2 , there is no going back. The bootloader exploit (loki doki) was patched in the 4.3 update.

Alright, tyvm for letting me know.
However you can run safe strap recovery and boot Samsung based custom ROMs like Golden eye ROM which is a really good ROM. I'm using it on my s4 with the MDL bootloader and loki doki.
