Hi,

I went through all the form to root my S4 verizon(unlocked) but nothings related to MG7 baseband??

my baseband version is MG7 is it different than others?? i coudnt find any post related to this version

Main problem is KNOX security is installed in my phone in system directory,

KNOX preventing me from root access(when i tried super user app i am getting a notification ""An application has been forced to stop for an unauthorized attempt to access system in your device"),

so i tried to uninstall the KNOX but I need a root privilage to uninstall it. I stuck in the loop.

after I found to bypass the KNOX I should use the certified application to get into root. (i may be wrong i am not sure) is their any way for me to root and install cynagenMod ?? or if helped in uninstalling KNOX i can root it.

Thanks in Advance.

FYI: BaseBand version is I545VRUDMG7 its verizon and unlocked now using AT&T

Are you sure it's MG7 and not MJ7? I did a quick Google search for I545VRUDMG7 and the only thing I found were the posts you created on this and other sites.

Maybe you could post a screen shot of your phone info.

Maybe some sort of test build? Did you purchase the phone used? Generally S4 build numbers have followed a pattern. The second letter generally indicates a date, I believe. That's why MDK was most likely a May 2013 build, ME7 was a June 2013 build, etc. So this may be somewhere in between ME7 and MI1. I would say this device could be a rare gem and may even provide more information towards a BL exploit.

Its very strange I could only find i9500 with similar build number but clearly that shows as an i545. Someone here will know. He says he has Knox on there though?

Wait you dont have root on this? Try saferoot or any of the root methods we have they should work. Next it would be helpful if you sent me your bootloaders would you be willing to help us? Also please refrain from installing Cyanogenmod for a little bit until I can get some of the partitions from your device. Also don't upgrade the baseband yet either please.

There was a reason they didnt release this build. It would be helpful to know why I need to analyze the bootloaders from this build. I hope you read this soon and above all else do NOT update your phone!

    @Surge1223 he had asked me couple hours ago how to pm you. So if you guys arent already in contact maybe shoot him a message.

    Sent from my SCH-I545 using Tapatalk

    I guess @Surge1223 can send you pm's on how to extract the needed files to find more about your bootloader. He could probably write a script for you.

    Yep he contacted me, we are in the process of getting the files. Thanks everyone for getting his attention. Ill post what I find in the bootloader thread.

    Google "VROOT" on your computer...install the app....hook your phone up to the computer...(green is "root" in chinese). Once you have root access, go to the file manager on your phone (preferably a root file manager) SEARCH FOR ALL FILE NAMES WITH "KNOX" IN THEM, AND DELETE....KNOX WILL NO LONGER BE ON YOUR DEVICE, but will void warranty....HAPPY HACKING!

    As you have only one post, clearly you're not very familiar with Vroot.

    Please don't recommend that people use that. There are far better ways to root that don't deliver unknown data to who knows where, and don't install shady superuser programs. Oh, and don't set the Knox Warranty Void flag.

    Sorry if you've already used Vroot. You should have looked further. For example, http://xdaforums.com/showthread.php?t=2565758
    That'll root anything vroot can, without voiding your warranty. Yes, that's a rooting technique that I built specifically to avoid vroot/kingo.
