I restored a nandroid of mf9. Got back to 4.2.2 but software version was still mja.
Guys should I wait until this all gets figured out with Knox and wait for a flashable modem/firmware that wont trip Knox or should I go for the update at the risk of tripping Knox and not being able to restore old twrp backups? This whole fiascal has me confused and worried about what to do.

I got tired of waiting so I downloaded the stock MF9 tar.md5 from sammobile (here is a fast mirror: http://goo.gl/gky86G, sourced from here). This one does not wipe data. You can verify it by opening it in an a program that supports tar and looking at the files within it... Those are the partitions it overwrites.
I used odin to flash it over my stock rooted MF9. Rebooted. Put the OTA on my external sd card, flashed through recovery, it booted up then once boot was finished it rebooted again, then showed a message that it was fully updated. All my data was still there.
Then I flashed cf auto root through odin, rebooted. Then flashed TWRP through odin, rebooted to check that it actually stuck, and I was good. The whole process didn't take more than 30 minutes (most of it waiting) and all my data was preserved.
It seems that with all the issues with the new firmware, that it's actually worth the trouble to do it the "official" way to make sure it works, especially since it's trivial to get root back. My hesitance was that I wasn't sure if going to stock via odin would wipe data (coming from HTC where everything was a zip).
EDIT: After flashing cf auto root, the su binary was installed (so root was available to apps, like Titanium Backup, Folder mount, etc), but the SuperSU app itself wasn't there. I just reinstalled it from the Play Store, opened the app, and it updated the su binary to the newest version.
This method was explained perfectly (especially with the links too) and worked perfectly. The only additional step I might add is flash philz touch 5.18.2 recovery (instead of TWRP) http://forum.xda-developers.com/showthread.php?t=2322679, with odin 1.85. then reboot, 3 button into the new recovery and flash UPDATE-SuperSU-v1.65.zip http://download.chainfire.eu/351/ from the main super user website, to keep root. all my backups worked with mybackup pro
Thanks for the help

- Stock UNROOTED: Temporarily removed
- Stock ROOTED: http://www.androidfilehost.com/?fid=23212708291674226 - MAKE SURE TO WIPE /SYSTEM AND /DATA
- Stock ROOTED: http://www.androidfilehost.com/?fid=23212708291676182
- MJA Stock Kernel w/ init.d and bootanimation.zip support: Temporarily removed
- Enables bootanimation.zip support instead of using Samsung's default *.qmg files. Includes a a Nexus bootanimation.zip so you can know if it worked. Also enables support for running /system/etc/init.d scripts at boot.
[SIZE=+1] HUGE HUGE NOTE. THIS DOES NOT INCLUDE THE 4.3 FIRMWARE. THAT WILL NEED TO BE PULLED FROM A 4.3 OTA'ED DEVICE AS SAMSUNG DECIDED TO PATCH THE MODEM INSTEAD OF PACKAGING THE ENTIRE THING.[/SIZE][SIZE=+1]Credits[/SIZE]
