Power Question.... AC and Onboard. topic

Long story, but had all my wiring done for the eMMC mod, plugged it all in - and my dog ran over the cables and I thought it was all good, but after that I couldn't get the eMMC to read - decided to make sure it was still good and shorted the resistor pads - but it wont power up now. I know the pad it good, but heres my question -

I'm worried something shorted with my dog incident - The wall Adapter is 16Watts, but when I meter mine its 6v - Is that common??

Next question, is there a good spot on the board to see if I am getting good power?

Thanks....

Just lost half of the pictures moving from on-board to SD topic

It is running CM 10.2.0-skyrocket and I just wanted to make some room on the phone for my senior mom by moving pictures to SD card and to my surprise half the pictures, if not more, is just a pixelized mess or just gray box.

Is there a way to recover the original pictures on-board storage?
