Should be either *#06# or *#0*#...i think

Ehh..what happen Uncle Benny..?

Yeap..it cannot even go into download mode then mobo fried edi. No worries..go claim warranty at service centre.
Btw..what actually happen..?
Takkan suddenly goes kaput

Not sure if it is just psychologically, but since upgrading to Malaysia Jellybean (im using Poland before) may batt seems to last longer. Fisrt time tha i've been able to use my phone for almost two full days and still have 53% batt remaining. Maybe it's just 2 slow days for me.

But antutu benchmarking saw a previous score of almost 10000 previously to almost 12000 (11997). So far im liking this, hell, im in love haha

you can download the firmware from sammobile and flash using Odin.

so many roms out there... dunno which one to use also... zzz.. me using checkrom currently...

so, that means just update OTA is wrong steps?

Like i said..decide yourself what you should do.
Dont blame anybody if your JB meet some problematic issue. Most common are lags..freeze..force close..and certain apps not working properly.
If everything works fine..then it's good for you.
If not working fine..then you already knows how to solve it.
