1) When I insert the USB cord in the USB port of PC, the Device Manager blinks (refreshed) and the 'Alcatel Single RNDIS Interface #2' listed in the network adapters in Device Manager (without any exclamation sign) as shown in 'DevMgr_1.png'.
2) Just within 4-5 seconds (instantly), Device Manager again blinks (refreshed) and come to the stage as shown in 'DevMgr_2.png' attached. Alcatel adapter is now having Exclamation sign.
3) The point 1 and point 2 told above go into an endless loop until I remove the phone USB cord from the computer
4) When phone is not attached to computer, the device manager looks like 'When_phone_not_plugged_in.png' attached.
Please go through the snapshots and advice further. Thanks.
I would've suspected a loose contact between the USB cord and the phone jack but something below caught my attention. Did you noticed that under Port, all Mediatek / MTK ports have exclamation / error sign with or without the phone connected? This is possibly where the No Com Port detected issue is coming from. Right-click on each one then uninstall. After Uninstalling, restart the PC. Back in device manager, Click Action at the top then scan for Hardware changes. You can then manually Install Vcom drivers using http://forum.hovatek.com/thread-440.html . forget PdaNet. You would need a working phone of the same model to install MT drivers using PdaNet and that you don't have
Thanks for the reply. I have followed the link and uninstall all the port drivers and reinstall them manually after restarted the PC. But, still the problem is there. Snapshot 'Driver_reinstall.png' attached.
The SP Flash logs still shows like --
