I didnt bring it all the time laaa, take a few shots then go back the the boat and flush the phone with fresh water. I dont have any lanyard on the phone too, Takut drop to the seabed also.. hahaha.. Dont be too worried with seawater, the phone is waterproof. As long you take precaution laa, flush with fresh water immediately after seawater contact. I even dip in the wash basin at the hotel after we're done snorkeling. Btw, beach side breeze is salty too, i dont see anybody so worried using their phone on the seaside pon. 

tink i juz brick my phone with flashing, keep restarting at sony logo now

huh? how did that happen? which fw u flashed?

flashed with some wrg firmware...

after tht re-download another firmware to get it working back, luckily, manage to update to 4.3 too

i notice that coc now only give notification if you turn on your screen. Is it the updated from 4.3 of it just the game setting update?

ooo... which fw u flashed previously that got problem?

and now which fw u flashed?

Nope, before that coc is not in the list as well.
Anyway, i'm prefer this way cause i wanna receive the notification only when i want to.

Some mod rom, apparently i have no idea on that, i juz random flash 1 and brick my phone with tht

currently flash with this :
C6903 14.2.A.0.290 Generic MY 1276-7939_R1B

if u browse using chrome, yes it drain faster. i don't like chrome although it's really fast and snappy. but it's also a very heavy apps, causing the phone to heat up and drain battery faster.

try using other browser like boat

Maybe you put Queue Background Data on?

any possibility the file that u downloaded is corrupted or what?

When use wifi, you normally will sit near to the wifi AP, so less power will use to get connected. But when use mobile data, i pretty sure you won't be sitting near to the tower...  you can look at the signal strength under setting/about phone/status... the lower the value, more power will be used.

yea probably, its smaller than the usual ftf file

just flash stock 4.3 ftf files, wipe everything except data.
check the MD5 hash if the OP provided any.
I just rooted my JB 4.3

I have .257 rooted (previously from .534) then I flashed .290 (JB4.3) without wiping data. then I have a non-working SuperSU left in the system, did not remove it.

now I flashed DoomKernel by DoomLord, booted into TWRP (not sure why CWM not working again) then flash SuperSU.zip from SuperSU's website.

done :B

nice.. so it works with theh traditional rooting way..
