[TUTORIAL][GUIDE]T-Mobile Downgrade from PE3 Marshmallow to NK3 KitKat

[n1nj4Lo]

You can't Odin to NK3 from MM PE3, so in order to do this you've gotta Odin downgrade to LP COK2 and THEN flash recovery flash the selected KK rom of choice and then whatever KK kernel ya can find that ya like, I've found that LLFK is still active and alive. You might also wanna Odin flash the KK modem too for better GPS location.

Samsung made it or tried to make it irreversible ever since COK2, it's impossible to Odin back down to NK3 KK, so you have to flash a rom, kernel and modem for matching baseband.

2nd: Odin Your Desired Custom Recovery
3rd: Flash Desired KitKat Rom of Your Choosing
4th: Flash KitKat Low Lying Fruit Kernel N915T: http://forum.xda-developers.com/note-edge/general/kernel-allows-selinuxpermissive-n915t-t3017469
5th: Odin KitKat NK3 N915T Modem: http://www.mediafire.com/download/s3l46lx7dfs26on/modem.tar.md5

Trust me I played around for a day and a half until I discovered it was possible to boot a KK rom off of COK2 and messing with Odin too, just a warning if ya don't flash a kernel you won't have working WiFi at all. Can't even Odin to LP 5.0.1.

I tried 3 times, regular flashing once, no kernel or modem, WiFi toggles would stick and just freeze as if they hadn't been touched and switched on, another time with the kitkat modem Odin flashed after installing the KK rom, again no response to the WiFi toggles no sign of WiFi connectivity, GPS location was better than no old KK modem and faster at picking up a location and then I flashed a kernel and suddenly everything was working as it should.

So does it allow you to go back to 5.1.1 from 6.0.1 by just flashing 5.1.1 In Odin with everything working?

Yes you can, no I couldn't go any further back than COK2 5.1.1 Odin firmware everything working fresh like new out the box, any earlier Odin firmware attempts ended in the fail error everyone is posting about, tried with BOD7 5.0.1 Odin firmware and got the same error as KK firmware.

TL;DR Simplicity - COK2 LP 5.1.1 is the earliest you can back to in Odin, I think COK2 locked the previous version firmwares bootloader, trying to make downgrading to Original KK firmware irreversible.

Cool, I just want to go to 5.1.1 maybe to check out some of those roms. I'm using tekhd 6.0.1 deodex and saw some interesting 5.1.1 roms I might want to try as I just received a note edge after trading in my note 4 for a broken camera that didn't focus so I'm ready to start roming this bad boy. But a simple Odin back to 5.1.1 and I'm good to go sounds great. I was hesitant to update to 6.0.1 as I thought I wouldnt be able to go back but did the update anyway. Thanks for the response. I'll try in a few days after playing around with 6.0 for a few days.

In theory you could probably go down to LP 5.1.1 just by flashing a LP rom and a LP kernel, I don't see why the same method wouldn't work for that. So before ya Odin get a good LP kernel and LP rom and try that out, I seen someone say to do that to LP for KK and that's what made me try and find out.

True, but I'll want to have a clean install for any rom I use on 5.1.1 just in case. Thanks again, team work makes the dream work.....of being a flashaholic. Lol

Do you have to be rooted for this to work? Honestly I just want to root my phone, but it seems like you can't root MM if you're on T-mo. I figured downgrading was my only option.

This thread should be a sticky

I can't seem to find any Kitkat kernels and LLFK dropbox links won't load for me. Anyone know where to get kitkat kernels?

EDIT: Seems it was a problem with my computer. Got it to load on my phone. But the Mediafire link also seems broken with a captcha that won't load properly. I'll see how it goes without it.

@MikeChannon Should this be stickied? @Zuffle I'll see if I can find a mirror or if db works me then make one myself.

Well a couple of things. Tutorials normally go in the device General forum so they don't get lost in a sea of question threads, but the decision about whether it should be a sticky or not I normally leave to the Forum Moderators who are a bit more in touch with what's happening in the forum and know better what should be stickied.

Theoretically this could be done for any version of the note edge, just remember to rollback and odin flash the matching version of 5.1.1 for your edge and then get the modem for it if possible and the kitkat rom of your choice, as well as root and twrp. But I believe and don't see why this side-step method wouldn't work for other versions of the edge and I imagine they (Sammy) locked the bootloader on all versions of 5.1.1, which is what people are getting hung up on in odin trying to flash 5.0.1 and 4.4.4
