Is there any way to use the files in the tar and dd to manually update my C2 running kszaq's 8.2.1.1 32-bit build? I'd like to try a little overclocking but I don't want to move back to 64bit.  

I was able to replace the u-boot in kszaq's 8.2.1.1 32-bit build tar with the one from wrxtasy and re-update my C2. So far I've been able to overclock the GPU, the CPUs to 1752 and the ram to 1104. My C2 has been running stable that way for ~24 hours now. I'm using the official barrel power supply and I removed the jumper to disable OTG mode on the micro-usb. Idle temp is ~45c and playback temp ~60c. 

What does the disbale OTG mode means? I mean what is the benefit of this? 

If you don't use the micro-usb port on the C2 to power it, you can remove a jumper and the average temps drop a bit (there was a post maybe earlier in this thread about that ?). OTG is for usb on-the-go, I think that storage mode is mostly used for android?
