S4 Revert Back to JellyBean from KitKat

Anonymous
Not applicable

Hi, apologies if this has already been posted (I have had a look and couldn't find it) but, is there any way to revert back to JellyBean from KitKat?

Really don't like the changes to the SD card stuff, and am reluctant to root the phone to fix it in KitKat.

Yes, you CAN go back to JB but you will trip the Knox fuse and void your warranty.
what changes to sd card are you referring to?

There are ways to do it, if you Google it, but you run the risk of bricking your phone. Your choice.

I'm told this is a process that can be seen by the manufacturer and can void your warranty.

With Sansung KNOX it is meant to be harder. Something to do with a more secure kernel. XDA developers will be the best way to triple-check the process involved.

I've went back the way using ODIN before, although this meant reflashing the whole os and having to reset my settings and preferences back up. KNOX is aimed enterprise security alas it does mean the average user can't flash their handset how they used to.

Originally the Samsung KNOX was meant to be rolled out to enterprise mobiles. I'm not sure why they locked out general consumers as well. Then again, someone that works in an organisation could use a secondary handset on an organisations intranet.

Perhaps @MI5 was right. ...... Samsung aiming to emulate Apple? That would be a sad sad day though
