I am using IDE 1.6.9....... And after updating Arduino AVR Boards to v. 1.6.12, I can no longer uplload to board. Going back to v. 1.6.11 and it works again.Tried this on Arduino Mega2560 and Nano. Same result.Any idea? Confused i have just bought Arduino products from this site <SNIP> in pakistan

Try a board from a different vendor (maybe a "genuine" arduino) to see if that is the issue (that is, buy one NOT made in Pakistan).

 

Just want to point out that Arduino is an open-source system and as such "genuine" Arduinos are determined by whether or not they have the requisite architecture and firmware. There is no reason an Arduino made in Pakistan or anywhere else for that matter cannot be as as "genuine" as those made anywhere else.

Actually there can be... Its something about the USB/Serial chip.. I've bought some before and the show up differently and state something like "unapproved" or something like that.. They still work but it does give a "warning"..

The Arduino schematic and firmware is Open Source, but not everything about Arduino is Open Source.

Their definition of "fake" is anything that misappropriates their brand name and/or logo. I can understand and go along with that.

No back to our regularly scheduled program...

I suspect that either your upgrade was incomplete or that you need to update the bootloader in the Arduino.
