Ok, i think i will flash to SIngapore version.
1 thing, i face some problem when connection to XS++
"iii) press connect
iv) turn off your phone, remove and put back the battery, connect the USB cable while holding C button.
v) select GDFS and press backup GDFS"
i hold the "C" button when conenct the USB cable to my phone,
XS++ seems like nothing happen, and keep showing "Detecting Phone, Please Wait.
Is "C" button means the same keypad area as numeric "7"?
Everytime i put back battery, Hold "C" and connect the USB cable, XS++ nothing happen,. but my windows USB detection keep pop up, do i need to bother it?
Please help, Thanks
