I have recently bought a Pro Mini from banggood.com, it isn't an official arduino board. I tried it out, and it worked fine. I managed to upload some sketches via an official UNO. But now when I try to upload a sketch, it fails with the following message:
Arduino: 1.6.6 (Windows 10), Board: "Arduino Pro or Pro Mini, ATmega328 (5V, 16 MHz)"
Sketch uses 9,782 bytes (31%) of program storage space. Maximum is 30,720 bytes.
Global variables use 540 bytes (26%) of dynamic memory, leaving 1,508 bytes for local variables. Maximum is 2,048 bytes.

avrdude done. Thank you.
Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.
My connections are:
UNO - Pro Mini
5v - VCC
GND - GND
Tx - TxO
Rx - RxI
RESET -DTR
The UNO is connected to the computer using USB, and no other wires are connected to either of the boards.
The chip is taken out of the UNO. I have tried reburning the bootloader to the Pro Mini, that was successful, and it uploaded the blink sketch. I believe the drivers are in order, because I can upload sketches to the UNO from this computer. Also, I have uploaded sketches before to the Pro Mini with the same setup.
What might have gone wrong? What should I do?
Thanks for your help!
