I've successfully UPGRADED to 532 Middle East version.
Thanks to everyone for their support and response.
Unfortunately I'm not that technical with regards to flashing and such and usually I spend hours if not a whole day trying to solve a simple issue.
Usually when attempting downgrading, flashing and changing roms and using custom firmware I get stuck half way through.
This ends up with a half working phone, boot loops, etc...
This happened when trying to get the 290 firmware, rooted with root. The part with regards to using a dual recovery was not too clear and this resulted in a bricked device.
I'm now back to stock 532, rooted & happy. To be honest, I didn't see any big differences with 532 and 290.
I cannot live without root. My bootloader is locked and unlocking it is a pain in the ass, lol.
I will patiently wait for the proper update of Android 4.4 Kitkat until I decide on upgrading.
I can only hope there is an easy rooting method of 4.4 when it's released. I don't plan on backing up data, reinstalling everything again, etc...
Let's hope when 4.4 Kitkat is released there is an easy rooting method which doesn't require an unlocked bootloader.
