I accidentally deleted all data from my htc one s, including the operating system. I tried to delete photos,apps and downloads, but it was still showing a memory issue (my phone has 16 giga memory and the "others" were using 10GB of it so i couldn't download more apps) and my phone was running very slow and even had some black outs.
I have team win on my phone. I went to factory reset which lead me to team win, and I choose to delete everything and didn't realize there was operating system in it too.
How can I reinstall my Android OS?
