SGH-M819N (Metro PCS) Mega update via Kies - Samsung Galaxy Mega

I'm seeing an available firmware upgrade via kies (MK7).
I'm a little skeptical to try it. Has anyone else upgraded to this firmware?
If so, have you been able to root your mega and install a custom recovery after the upgrade?
I don't want to install this firmware upgrade only to find out that afterwards that knox is on it and prevents me from rooting the phone or unlocking the bootloader.
By the way, I tried downloading the firmware without my phone connected but kies keeps force closing on me before the download is complete.
I'm afraid to connect my phone and try the download because I think it will automatically install the upgrade which I don't want to do until I'm sure I can re-root it and re-install TWRP.

I bit the bullet and gave it a shot. I am happy to report that the firmware upgrade was successful using Kies, I was able to root the device via the Kingo Root app, and was able to re-install TWRP. I am now on firmware M819NUVUAMK7. It is still Android version 4.2.2, and the baseband is also M819NUVUAMK7. The kernel version is dated Fri Nov 22, 2013
I installed superSU and when I ran it, it asked me if I wanted to disable knox (YES OR NO). OF COURSE I DISABLED KNOX!!
I afterward performed a nandroid backup in TWRP (the first order of business).
I am more comfortable now deleting, freezing, uninstalling system apps now because (in the event of a softbrick or bootloop) I can always revert to my nandroid backup or in extreme cases, restart all over again by re-installing the firmware via Kies, re-rooting the device via the kingo root app, and reinstalling TWRP via ODIN.
Not sure what changed from the original firmware (no change log). In any event, the device is snappy and I'm not experiencing any lags.

as far as i know. there isn't a mod for Metro's phone. there are a few custom ROM's you can use that have free tethering built in. This one is the closest to stock. http://forum.xda-developers.com/showthread.php?t=2608110
It works fine on my M819N :good:

well easiest way is. if its your stock ROM that came with the phone when you bought it. it is odex.
if you are rooted, you can use root explorer to go into your system/app file and see if it shows odex settings for apps

I did and had no problem rooting with kingo. What I cannot find is a way around sim lock without going through metro and that sucks.

Almost had a heart attack from this upgrade. My phone was already rooted when I applied the update from Kies. Everything went through fine except when it restarted, I couldn't turn on Wifi at all and I was getting an E in the cell signal. I managed to download the TWRP tar file and Kingo app to root again. I was able to restore my previous backed up image and everything was when I last left it! WHEW!

---

That's strange. I had no problem. wifi worked and I haven't seen E at all (only 4g lte or 4g). My signal appears to be stronger and more stable with this update than with the original firmware (most of the time I have full bars). As mentioned I don't know what changes were made (no change log around) but this is my observation so far.

Can somebody running MK7 please boot into download mode quickly to check whether this update has a new Knox bootloader?
(Vol - , Home, Power)
Need to know if the following strings are present or not:
KNOX KERNEL LOCK:
KNOX WARRANTY VOID:
BOOTLOADER RP SWREV:
Thanks in advance.

This string is present on my phone in download mode:
BOOTLOADER RP SWREV: 3
I have no lines displaying anything about KNOX.
In titanium backup I froze knox 1.0, knox notification manager 1.0, and knox store 1.0.
So it appears that knox is in the rom somewhere but it's had no impact on me. I'm rooted, have twrp installed and have flashed multiple custom roms on my device (both tw and aosp based roms).

---

Perfect, thanks! Glad you guys got spared from the horrid new Knox bootloaders. There's a small chance that the M819 can be downgraded to the older bootloader to remove Knox entirely, but if the update came with the newest bootloader (I got stuck with it on my i527M) there is no hope at all of downgrading.

Thanks to whoever posted this and the creator of this rom

I have the sgh-m819n metro pcs model running the mk7 firmware. This was the only rom that worked 100% for me. Im running twrp recovery,super user and free hotspot. Not to mention all the extra cool apps that it comes with. Big props to the developers of this software may your days be blessed with many more hacks.

http://forum.xda-developers.com/showthread.php?t=2608110 this is a great rom for our mega(metropcs) imho. now in order to install CWM or TWRP you simply need to download the version thats for meliusltexx which is for the i9205 version of the mega.. These Roms and procedures are compatable with the M819n(metropcs) mega

I miss my LTE data speeds. if you know how to fix or anything please point me in the right direction thanks.
