[Tutorial] How to fix MTK or SPD bricked after interrupting flash or backup
(13-02-2016, 05:49 AM)aaron89 I've an BQ Aquaris E5 FHD (MTK6592) and today I decided to update to latest firmware version via hard reset using SP Flash Tool, the first time the process was interrupted without reason, so I tried for second time and everything was OK, the phone was able to boot normally. 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
(06-11-2014, 02:48 PM)hovatek This guide is for MTK devices like Tecno, Gionee, Micromax, Infinix, Opsson, etc
If you dont know how to flash files using SP flash tool, follow this guide @ http://www.hovatek.com/forum/thread-159.html .
If you wish to do a read back / ROM dump using Sp flash tool, follow this guide @ http://www.hovatek.com/forum/thread-526.html
What you should know about SP flash tool is that you shouldn't interrupt a flash or read back process. If you do, the phone will go off and not come on at all. You might get the "USB device not recognized" error on further flashing attempts. If somehow, the process got interrupted and you now have a totally dead phone on your hands, don't panic. All you need to do is connect the phone to a computer (via a USB cord) or power source and leave it to charge for some time. It could take up to two hours but once the phone is revived, your battery could read as low as 1% . just leave it to keep charging before powering it up.
Tips to speed things up
* Remove the battery > Connect the phone to a charger without battery inside > Slot in the battery while the phone is still connected to the charger
* You could keep pressing the Volume up + Power button while charging
* You could remove and boost the battery using a desktop / external charger then resume internal charging.
* Uninstall then re-install MTK preloader vcom drivers using this guide @ https://www.hovatek.com/forum/thread-440.html
