After googling for about 8 hours, and going through many-may websites (including HIGH-LOW tech) I found only one working set of hardware files for attiny that got it running. Hope it saves your time !

I didn't visit that link but this is certainly the best one:
The hardware package from the high-low tech website (damellis/attiny) also works fine though. What problem did you have with that one?

GitHub - SpenceKonde/ATTinyCore: Arduino core for ATtiny 1634, 828, x313, x4, x41, x5, x61, x7 and x8The hardware package from the high-low tech website (damellis/attiny) also works fine though. What problem did you have with that one?
For some reason, The cores downloaded from the highlowtech dont show up in the IDE,
Thanks for the above link tho!
