Arduino lilypad not in sync

Hello,
first of all I have to say that the arduino lilypad I'm going to ask help for is not a genuine version, I'm using it for a throwaway project so I just bought the cheapest version I could get.

If that's not a problem let's get to the point: I got a prolific USB-to-serial and this arduino lilypad. Installed both drivers (PL-2303 and CH341SER) and so far everything seems to be working fine (COM port is recognized and so on). The troubles start when I want to upload a simple blink sketch to the lilypad as I get the following error:

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x67
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x67

Now, I made a lot of research before starting this thread, I tried to swap TX/RX, tried to swap atmega328/168 on arduino IDE, tried to use "arduino uno" instead of "arduino lilypad" (still on arduino IDE) tried to use different drivers but so far nothing seems to work and I have no idea how to get past this, so this forum is my last resort, any idea how to fix it?

Thanks for reading

try to switch on verbose output during upload it worked for me and many others

nothing changes, still not in sync error
edit: it works with verbose + arduino uno as board, thanks!
