Android 4.3 finally on my Galaxy S4

OK, so I really didn’t put Kitkat on my S4 but I did put Android 4.3 on there. Most people will be able to upgrade the S4 with an OTA or KIES update but if you’ve modified your phone by rooting it then that doesn’t work without intervention.

That intervention relies on flashing a “stock rom” on the phone which is just as risky as flashing the new rom so I decided to wait until it appeared here and then grabbed the file, backed up my photos, music, settings from various apps and with some trepidation fired up Odin.


Odin is the tool used to flash Samsung Android phones and once begun, the process is painless.

So, Knox started complaining about the apps on my phone that needed root access to work. Get rid of that then! Thanks to CF Auto Root that was easy. Flash that on there with Odin and Greenify works once more and Facebook is hibernated. I sent Chainfire a donation too as I’m sure this is about the third time I’ve used his tools.

I haven’t noticed many differences, or really any except that Disk Usage works a lot faster now because of the TRIM being done on the flash memory.

Oh yeah, before I forget. I won a bar of chocolate with that KitKat. Got myself a nice Yorkie this morning. Didn’t win that time though. Ah well.

Edit: Noooooo! Knox stopped Disk Usage from scanning / which requires root. Greenify still worked which is more important but I guess Knox has some parts of the system still locked down.
Chainfire has more info on Knox and how to disable but also this bad news that disabling Knox may void any warranty on the phone. Grrr.
