+# Why a reset to factory defaults
+
+Sometimes with an update some settings management is changed and render the actual settings set in various place not working correctly or clearly killing some apps.
+
+To resolve this you can try to reset these settings. For that, you'll have to clear the persistent settings and clean some directories on your SDCARD.
+
+# Guide
+
+The best way to achieve the reset is to take out the SDCARD and do the cleanings on it on computer.
+ 
+Boot the unit without the SDCARD (you may need to press your boot key), get into the 'Settings' / 'P.Memory Mgmt' menu and clean the persistent memory using the button. 
+
+Shutdown. 
+
+While you're at it update the SDCARD content to latest if not done. 
+
+Put back the SDCARD.
+
+Boot (may need boot key). 
+
+You can now use your device like if it was installed first.
+
+## SDCARD
+
+### 'SETTINGS' directory
+
+Delete all the files under 'SETTINGS' to reset "App Load and Save" settings as well as the configuration of the "P.Mem" menu. (note: this does not reset the persistent memory itself).
+
+### 'hardware' directory
+NOTE FIRST: this reset the saved boot config key. 
+In case you think it's not booting because of a bad saved detection, delete the file under that directory.
+
+## PERSISTENT MEMORY
+
+Get into 'Settings' , 'P.Memory Mgmt' and click on the '! reset p.mem, load defaults !'. This reset various settings in apps like i.e Recon app.
