This topic was discussed before but not solved.
I tried to reply but no reply activated...

Arduino Pro Mini; does not take load from loader
it gives the following error

avrdude: stk500_getsync(): not in sync: resp=0x00

connection as below:
Arduino       USB loader
TX                                  RX
RX                                 TX
DTR                             DTR
VCC                              VCC
GND                           GND

I tried all tricks on youtube, here and on instructables...not working...among which I tried:
 remove the TX pin before loading...did not work...tried press reset button (between compile and loading stage, before and after...all possibilities...nothing worked...) tried a capacitor to DTR...and DTR to DTR...nothing worked...Anyone please help...

Maybe there's no bootloader installed?

I found the USB suitable driver and installed it. Now Win7-64 fully recognized the USB loader, and marks it as fully working..
but that error massage which is being debated all over the net remains without a solution...!!
