Reset all Android data via HardReset?

Question

Android

Good day. Recently, while climbing Google (from a mobile phone), the phone hung, then abruptly turned off and that's it ... After turning it on, something like this: "The Launcher application unexpectedly stopped (the com.android.hylauncher process), try again). Therefore, the phone is for me was instantly blocked. After digging in Google, I found that I need to reset the settings. Ok, I think, let's reset.
The easiest option is through HardReset (sound button + switch). I use this feature and what I see ... Instead of the expected Recover menu, "Spreadtrum Factory Test phone test. Factory used" and in these menus there is only a test for the phone's performance. This problem put me in a stupor ... Googling the answer was 0 ... Help, if you know what to do, please.
