[Q] Options for upgrading to KitKat from 4.2.2 with TWRP

dodgeboy · Feb 14, 2014

I stayed on 4.2.2 rooted with TWRP and never took the MJA/MK2 OTAs, to avoid knox. I've been waiting for KitKat, and I'm ready to take the plunge. I've read through a bunch of threads, and have thoroughly confused myself. I have a few basic questions, so I can determine what my options are:

1) Is it possible to go from MF9 (rooted) to NAE, and retain my data? What happens to the modifications I made to MF9 (hotspot, xposed, etc.)?
2) If the answer to 1 is no, is it reasonable to assume that there will be a flashable NAE rom in the near future, so that I wouldn't have to odin to MK2 before going through the OTA update to NAE?
3) Should I give up on trying to keep my existing bootloader, and just suck it up and take knox? It seems like there's probably enough differences in the rom and modem that the bootloader is probably a necessary evil at this point.

Thanks in advance for your help.

There have been several reports of people whose WiFi and data have worked just fine with the NAE ROM plus older bootloader like MF9. I'd wait until a stock rooted NAE ROM appears so we can try it with the knox-free MF9 bootloader.

I am in the same situation and currently on a stock rooted MF9 with a custom recovery as well. I would like to know the best upgrade path to 4.4.2 and hopefully stay on a knox free boot loader.

Once Warboy releases the updated stock, rooted NAE, I'm gonna flash it with Philz recovery to see whether everything's compatible with the Knox-free MF9 bootloader. In the meanwhile, I'm gonna flash just the NAE modem. Cant wait for Kitkat~! (Even though I've had the 4.4.2 update for a long time through my Nexus 5, I'm still very excited, LOL~)

I was on this boat but last night flashed the gummy Rom. It is okay but I would love to have the stock Rom. I don't like few things on the Gummy.

so you had MF9 bootloader? (and do you keep that one or switch to the knox one?)

just flashed rom with TRWP? (that'll update radio too?)

and what things dont you like on Gummy?

Lol I've been wondering if anyone else stayed on 4.2.2. Lol Im rooted with custom recovery. I hit the update button the other night and it wouldn't install and that icon went away, so I got that going for me. But I can't wait for kit kat, just waiting on the whole knox deal.

Yeah I have MF9 and I could keep the same.

I had issues with BT connection with my BMW but works fine with BT headset.

Home screen kind of wacky and you can't select the one that you like.

I just went back to 4.2.2 again until I find a good one.

I'm in the same situation, living on my phone with MF9, have TWRP/Custom Recovery installed, and am interested to upgrade to Kitkat. I'm very interested to know what will be the upgrade method for me to 4.4.2, similar to many others in this thread.

Which KitKat rom did you use? Did it just upgrade your OS or did you have to start from a clean install? Any issues with Knox?

i used Slimkat, but it froze occasionally. now im on CM 11 and its FLAWLESS
did clean install (but had some apps backed up with Titanium)
to my knowledge the whole Knox thing is with Touchwiz based roms
both slimkat and CM 11 are not,so no worries about Knox

I am still on MF9 modem and bootloader
gonna get around to flashing the NAE modem later though

Alright. I'm personally looking to update only to official rom and NAE modem, not custom rom. Hoping I can do upgrade instead of clean install but hoping to get root access back or keep it at least.

Ok so i dont think i care about the knox thing anymore.. So with that said i would like to upgrade to 4.4.2 with the stock sprint rom. What is the best way to go about that? Sorry im just confused with the bootloader and modem flashes.. Its been awhile since ive had a samsung phone.. Im assuming i cant do the OTA due to TWRP....

I am running completely stock and rooted with saferoot,

4.2.2
baseband mf9
bootloader mf9
TWRP installed

please help

Can you just unroot and install the NAE ota then reroot with cf auto root? This is coming from stock rooted mk2.
