I finally got around to sourcing a new battery for my Zod, but I can't get the back off!
Undid all the screws with the insanely tiny torx driver, but there appear to be 4 clips or something holding it in. I have applied considerable force to the point that the metal casing of the back has started to bend slightly so clearly there is a trick to getting it off... but what is it?!
Also, it looks like the old battery has swollen up something scary, which I suspect is why the button has been crushed on; I hope it isn't permanently damaged...!
