You're using LTE or 3G version..?

And your SELinux already enforcing while your Knox flag is 0x0..?
You're on what firmware now..?

Try take a look at the link below for the prerooted ROM.

If you wanna try official full stock firmware... Only Germany available at the moment. You can flash that firmware (get from Sammobile) without tripping your Knox warranty flag.

Which firmware more updated....M'sia one..?
Doesn't matter...you can flash upgrade or downgrade your firmware as long as it's between official stock with Knox bootloader.

Do not try to downgrade to the older non-Knox bootloader firmware as it will surely triggered your Knox to 0x1 if you do so.

wah, this post quite useful for LTE user.. is time to read it up!

aye.. dun wan....
coz keep jumping the ship(i means smartphones), your will gone faster la..

regarding the lagging of 4.3 update, i managed to factory reset my phone and now it is working flawlessly.

i backup using kies and helium. kies mainly for contact but unable to restore apps and their data.

Helium is awesome and managed to restore all my apps and saved games. Only downside was after restoring Waze, it caused waze to crash. Had to delete and reinstall again. But thats just minor issue.

thanks to everyone for their advice. btw my phone is not rooted.

If i were you, ill avoid HTC as much as i can. Not being a fanboy, but i have a bad experience with their HTC One S. Im scared with their quality and SC here
Even Google now is taking serious about modding and stuffs. Just look at KK4.4 . its already has Enforcing SELinux by defaults :sweats: , unless you dont mind stock, thenyou are good to go
