haha yeah, good impression on the customer support even the guy at the shop was surprised. he said mine was the only set which had this kind of problem. and luckily that time, there was only ONE red set left for me to grab haha and the next customer who came in right after me was looking for a red ZF5 too. hehe   phew

ZF 5 firmware its about 660mb........

before you update still got sound on the speaker? 

after long use, do u guys experience the phone slows down, or become more lag? and also, how long doe it take to fully charge? does it have smart charging like lenovo?

slow? maybe..i don't really know..maybe it's just my imagination coz i'm used to its speed now.. 
fully charge maybe takes about 2-3 hour
smart charging is what? phone stops taking current after battery is fully charged to prevent overcharge? if so, then got

just to share my experience here..

this apply to Zenfone which is running on DEMO MODE due to failed rooting or failed firmware update or any reason.

if you try to root ZF5 & failed, the phone will automatic activate the Asus Demo mode. in this mode, Demo mode will play videos & show the specsheets of the phone each time u press power off button. it is similar like the showcase unit at shop. not much u can do with ur if u are in this mode.

to turn off the Asus Demo mode, below is the steps. the phone will deactivate the demo mode, delete it & reset the phone to original factory settings.

1.turn on phone, make sure u are connected to the internet over Wifi.

2. run the demo mode. < while on home screen, press the power button to turn off screen & the demo mode will start.

3. when demo video is playing, tap the scree to stop it. u will land at demo homepage.

4. at this demo homepage, press & hold 'back' softkey more than 10seconds until a deactivation screen appears.

5. in the password column, pls key in password: 741603 then press deactivate. this password works for all Zenfone model.

6. the phone will restart & erasing the demo mode & resetting your phone to factory settings. pls take note this will take times like 5-10 minutes. if it takes more than that, means something wrong with it.

7. your phone now DEMO MODE DEACTIVATED & running like normal..

so u still feel the smoothness la since first use?
i dunno the correct term, for lenovo the got smart charging. 3 steps charging. rapid, normal, and very slow until full 100%.

there's no low light icon on the video button or there is but it doesn't work?

Zenfone can disable app (not all) unrooted... +1 for this...

Seems like rooting is not needed now...

also you can install (not all) games into external memory...
at 1st i was skeptical...
but when i see it install 2 big games from gameloft (worth 1gb each) on external memory then i puas hati...

so i can hold 1st from trying to root and wait for a proper/working root method.

ZF4 already got root from website that i quoted in my post, but 4.5 i not sure but should be same..btw new small update ZF5 FW can be root again, 

4.5 not working...
already tried that yesterday...

not the ROOT apps and i know that  btw you already try through ADB (Droidboot) method before this? 

u mean the one have to restart phone and push on with sound button...
then use command prompt on pc to root??

if that, then yes i already tried it...
and not working too...
plus when i checked the folder it was meant for JB...
as ZF4 use JB (not sure if it can upgrade to kitkat now or like ZF5 still using JB)

ZF4.5 already equipped with KK? 

disable apps no need root and its already known long time, but mostly user root purposely for removing the apps permanently not just disable 

yup out of the box...
