My Galaxy Ace doesn't get recognized by my HP laptop with USB connection. When I tried to connect it with my friend's cable on his Dell laptop, it notified
CONNECTION UNSUCCESSFUL - NO DRIVER FOUND. My phone still gets charged though. When I tried the
*#7284# solution it wrote:
DIAG CONFIG USB[*] UART DBG MSG ON DBG MSG OFF[*]
USB[*] and it gave me:
USB_Diag Selected Change Complete. IF you change Uart or USB diag Please reboot the mobile.
I'm not able to find MODEM->PDA mode.
