just found my own solution for wifi connectivity..
need to assign ip address manually for the phone inside router

the simplest way is just assign ip address within the phone, no need to do it in router..
goto wireless>select menu>advance>assign ip address there

Example:

ip address : 192.168.0.10
gateway : 192.168.0.1
netmask : 255.255.255.0
dns1 : 8.8.8.8
dns2 : 8.8.4.4

this is for unifi, for streamyx just change 192.168.0.1 to 192.168.1.1
and 192.168.0.10 to 192.168.1.10

weird, mine works flawlessly

did u set MAC filtering on ur modem or router?

my wifi kinda weird, connected but cannot surf.. im having another phone, samsung which got no problem.. HELPPPP

Thank you!

I downloaded UnivsersalADBDrivers.msi and ishuaji_root_sj.exe, will try later.

Is there anyway to completely format the phone, like what we do with laptop? I want a clean phone by default, rather than uninstall the bloatware 1 by 1.

*Edit:
Also, if I root, remove bloatwares then factory reset, then the phone still remain rooted or I need to re-root again?

Aiks very frustrated now. Tried many ways also can't solve the drivers problem :/

just try again and again you will success... try disconnect and connect again... make sure enable usb debungging and tick allow mock location on setting... ur antivirus must be disable before install ishuaji root and root your phone..

I installed superuser, but when I use Titanium Backup to uninstall CallerTunes 1.01, it say "Cannot remove system app, failed to locate the apk file".
When I use Link2SD, it say "Uninstall not successful".

Any workaround for this?

After rooting with Mgyun,
these apps is automatically installed.

Since i already installed Titanium Back,
Is it safe to uninstall that chinese app? (whatever that is.)
and what the heck is that app?

U know, I did just that, downloaded Superuser from Google Play first, and used ishuaji. According to ntuser, I succeed, but everything is still in chinese and it stated that I dont have proper root xs. When I tried to update the binary for english Superuser, everything went smooth til the last part, it says failed to gain root xs.

is it okay to swap wif 2gb memory card given when u bought the phone?
