Bought a htc one m8 from a "friend". It came already with Team Win Recovery Project, so it means that someone installed it.
"Inside" the phone, the icons on the app screen are smaller than in the common HTC's (grid is 4x5), which i believe it is a failed custom ROM that someone installed (am i right??)
When i press POWER+VOLUME it enters in that "crazy" menu and, on top, it says S-ON.
How can i wipe all of this (including this TWRP) and restore all default factory settings, so my HTC app menu looks like everybody else's?
Although, i want it to stay unlocked as it is.
I do not intend to root it for now, or install any custom rom (for now).
Sorry about my English,
Thanks in advance,
