I was thinking of buy the HTC One M9 dev.How can i get the image to turn my phone how it came when i got it?Does it get hot the phone what i been reading on it? And where can i get the image for it on the web site?
I assume you are talking about returning to stock. It is probably not a good idea to return to an out of the box state. Flash the latest stock image instead. You can get the stock to images from the HTC website. If you are rooted and running a custom rom, when wanting to return to stock, I would go over to XDA. Here is link to a collection of stock roms. You would need to make sure you flash the right one for your carrier.
