WITH OUT holding to button software shows following message in RDA SC6553 Boot 4 option:

And when I tried ReIMEI with a different IMEI number in IMEI 1 option box, following text appears:
Definition Applied

Done.

>>BootLoad Error. ID: 19
After this message telephone power on (boot) itself.
I also tried while button is pressed, but it makes somehow confusement in device and computer communication.
What I noticed is, there is no option for an 8809 while device manager describes the device as "RDA USB Driver for gallite 8809".
Also when device is on, device manager shows 2 Coolsand devices but as drivers are not installed.
Actually you can see them on 3rd post's attchments.
