NO, it is not normal (the phone display should remain black). This is a driver problem. So install the driver what comes with SETool2 Lite v1.11: You can follow the USB Flash Driver Installation - Guide, but use the driver from [SETool2 Lite v1.11folder]\drivers\USBFlash_driver\ folder, and it should work.But what I noticed is that when I press the "C" key and connect the cable the phone goes into the usb data transfer mode and windows brings up the window to view the files and folders on the phone. Is that surpose to happen?
Here is a jdflasher tutorial: JDFlasher DB2020 CID52. But please bear in mind to install the good driver first.
