Sprint Note 3 downgrade from lollipop to Jellybean pls..

[bitz017]

Hello guys, I'm really just trying my luck on finding someone who can help me with this (or at least direct me to a thread or something..)

I've got a Sprint Galaxy Note 3 which is currently working with any network except for a couple of things I want addressed:

*I wanna downgrade back to JellyBean bexause there's an app that I need to be working (yes, it's more important to me than getting the latest android features)

*I wanna keep the phone *carrier-unlocked* (I was told that the phone is factory unlocked, and given that the phone has Sprint branding..it always goes on roaming mode just for it to work where I am (Phillipines), and I wanna fix that.)

So, with that being said, I just need help on where to start and what order should I be following to achieve these.. I'll be okay with stock Android JB but I want to use a custom rom as much as possible..

P.S. - I've tried reading the forums, and have been reading the forums.. it's just that I cannot seem to find something that would give me the result I want..

Any help would be much appreciated.. Thanks in advance for those who care to help..

Once your device was upgraded past MJ4 (jellybean) to NAB ( first kitkat based rom ) Knox was installed and as the device was upgraded past KK to OC2 lollipop Knox security follows making it impossible to go back to jellybean.

regarding this process, say I have Lollipop installed, and don't care about tripping knox. Does it still make in impossible to go back to JB?

thanks for the response

Yes it is still impossible to downgrade. When the device is upgraded to kitkat and beyond several changes are made to the bootloader/modem. If you try to downgrade the bootloader/modem to MJ4 you will brick the device.
By tripping Knox all you are really doing is breaking the knox security system ( meaning Knox containerization of data is no longer possible ). What you might be able to do is root your device with a OK2 lollipop with a custom recovery. Then make a BACKUP of your rooted OS ( click on rom flashing basics in my signature for more info). Now you could try to find a jellybean based rom/OS and see if the device will boot up. The worst that can happen is you will soft brick the device ( it boot loops on start up ). To solve this just pull the battery and replace then boot into recovery and flash your backup and then try a different one.
