[Effects of different voltages]

Im having issues with mine, I got a MKV but the battery that came with it outputs 12.6v, I cant boot it from the battery at all. What could possibly cause this? It tries to boot but shuts off and wont turn on unless the cable is removed for a little while.

[Micro SD not Detected]

Hi guys Just recently purchased a MKV, while playing witt it i noticed it got a little slow, so i did a firmware reset (flash) accidentally i had the Micro SD card out and now it does not detect it, i tried re-flashing with it on but it still doesnt detect it. I was able to mount a USB but i am unable to see the micro SD card, I did try a SD card but it was not detected. im out of ideas as to how to fix it. Any help appreciated!
