IWR1642BOOST: Unable to flash using UNIFLASH tool; Tool hangs

I am trying to flash the image to the device using uniflash versions (5.3.0) and (4.6.0). The tool is highly unstable and I could successfully flash only 2 out of 10 times in both Linux and windows. Everytime it reports different errors even though I follow the same procedure. Currently I try to flash the image in windows 10 PC, a pop comes up and it says 'Load Program, Please Wait, Initialization complete' and it hangs there.

Please find the screen shot attached.

I followed the below procedure while flashing,

1)SOP2 jumper is put on.

2)Powered up the device and pushed the reset switch.

3)COM ports are successfully detected (COM 3 : Data Port and COM 4: User UART)

4)Run the Uniflash tool (Windows 10 , Uniflash version 5.3.0)

5)Selected the 'IWR1642BOOST' device from device list and clicked on start

6)Selected COM port as 'COM4' and unchecked erase Sfalsh option

7)Selected the *.bin file and clicked on Load Image
