As I wrote my backup doing by "Mediatek USB Port not "Preloader" ....
But at now I'm pretty sure it hardware issue due to strange behavior in Flash mode. This issue meets at MTK phones wich support OTG. A living phone it does not affect the normal operation Only question on GSM repair forums " Why my phone can charge only when power off ?" Reason phones independently moved in OTG mode(phone as host !) due to a fault so called "Charger Switcher " It is IC may be series FANxxxxx(Ex. FAN54013) and environment element (nominal leak of resistors or capacitors)
When you begin to update it appears periodically(small leak) but flash content was damaged
At now critical leak of nominal and it constantly in OTG mode.
