[Sprint Samsung Galaxy S III] easyrider77:
Correct. I am HUGE on research and study so I researched different phones and weighed out my options vs phones vs look/feel etc....so I did my homework. I read up on knox and what it was and the work around and what not, so the phone came packaged with 4.1.2 android, which does nt have knox, the next update is MG2, then MK5, and MK5 is 1: android 4.3 and 2: it's where knox comes into play. In short, so you know I understand what yer meaning, knox is a fuse trigger of sorts similar to the same thing on xbox, playstations etc....and triggering it is done by basically a modified bootloader or useing pc odin, and is almost guarenteed to trip it. Knox starts at a value of 0x0 and if tripped it sets to 0x1, and cannot be reveresed....(yet) they are close to a workaround I think. To simple analogize it it's basically like a house fuse or car fuse....it's a one time trigger/trip...once it's tripped there is no way back.

Since I saw the phone with 4.1.2 I checked to see if it had knox by entering download mode and sure enough NO knox, I was happy....so I rushed to find a rom and root immediately. I used the OTA fix and the nag went away, so then I proceeded to find a rom, that's what lead me here where I am now. In this last day or so I have flashed multiple roms, be it 4..1x on up to KK, and very few of them are working in my case.

All this being said, it's not knox'd up, but I am not sure if the bootloader is still MD7 or if it is upgraded to MG2.

Since I haven't found a way nor does anyone know of a way....to check what bootloader you are on, I can't say for certain what it is.....only thing I have to go from is I did the following from this thread http://androidforums.com/boost-mobile-galaxy-s3-all-things-root/758586-odin-backup-sph-l710_mg2.html and assume I have MG2 bootloader, but again I am nt 100% sure because I don't know how to check and see.

I was told once you go to MG2 (and not MK5 because that has knox) that you would then be able to upgrade/flash to KK fine without a problem, that's why I did the thread above way, assuming it would give me MG2.

Sorry for the length some times, I just wanna make clear the devs and others know I am clear on the understanding of stuff is all :).

Update:

sdcard issue fixed.....it seems the roms have issues with 32GB card...I am now on a 8GB and everything is working fine.Issue resolved, but now I have a new problem to replace it, although not a URGENT issue......I installed viper to make the sound louder, and now my alarms and notifications don't work at all, no sound period lol......from one issue fixed now another crops up.

So success then failure all in one....wheeeee

I guess until I can get a fix for the roms issues, I'll move on to touchwiz I spose, although I dearly love aosp, but it sure does not like me right now.

I'll keep looking and hope for a fix.

In the mean time I am going to try one last ditch effort at this as a work around, in hopes they didn't bypass the MG2 update and go directly to MK5......I am going to flash back stock un-rooted, except the firmware updated, and as I said hope it will do incremental updates and not go directly to mk5.

If it does indeed go directly to MK5, then I will be holding off and put on pause, JUST to make sure there are no hardware issues before I void warranty......I figure a good month will do the trick, although I realize there are n guarantees it won't happen down the road, but still, better to be safer than sorry.
