Then I noticed that the serial number was wrong (0123456789ABCDEF) so I powered off the phone and wanted to correct it using IMEI Sn Writer, but for some reason it couldn't connect to the phone, so I disconnected the cable and the phone was not able to boot anymore. The phone seemed bricked, every time I connected it to Windows appeared as "MTK Usb Com (COMx)". I think it had corrupted preloader so I spent hours and hours reading forums and trying to flash preloader with SP Flash Tool without luck. I had read this topic so the last try was leaving it charging and voila! after 1 or 2 hours it booted and showed the battery charging animation with 50% of battery, then I disconnected the cable and connected again and it started charging from empty (0%). I suspect this is because some battery calibration data is lost after unsuccessful flashing, it's strange.Have you been charging since you saw 0%?
I left it about an hour connected to PC with SP Flash Tool running in download mode with only preloader selected, then suddenly I noticed that the phone got disconnected from PC and the application showed flashing error, so I tried to disconnect and connect the cable but the phone was no longer detected in PC, I was scared that the brick got worse but then I connected to wall charger and booted to the charging animation, I waited until it reached 50% and re-flashed the whole firmware again and since then phone is fine
