How to re-install New Smartfren Andromax Tab (NSFAT) 7.0 with Android Jelly Bean 4.1.1 Build 60.5 (Stock ROM)

I have a tablet New Smartfren Andromax Tab 7.0 a.k.a Hisense WM7 a.k.a WonderMedia PRIZM 8950 , and tonight the tablet acting weird . At boot time, the display stops at the logo " Smartfren " and not entering the main menu of Android . I have tried to do a hard reset on the device but does not solve the problem .

I 've tried to bring this device to the nearest Smartfren Gallery . They said this device must be delivered to the Smartfren's service center at the Roxy - Central Jakarta , and it would took at least 2 weeks . No way man , I can't wait that long .

Finally , I decided to install this device by myself :-(

UPDATE : I think i've found the culprit !
Yes,  I think i've found the culprit! It seems that the Bluetooth is the root cause of the bootloop. I used to reinstall this tablet once a week. But unconsciously, i never use Bluetooth since 2 months ago.. and this tablet never gone bootloop again. Wifi is safe, you can use it all day long. So, try to turn off your Bluetooth, and let's see the result!
