I need to flash a new firmware for my china X-302 Tablet (detail below). From the producer i have got a package containing firmware, stock rom, sp flash tool, drivers etc. When I want to use flash_tool.exe select and add download agent (for example MTK_AllInOne_DA.bin or more) then pops up an error:
ERROR BROM: S_FTHND_FILE_LOAD_FAIL (5008)
Tablet at that moment I connected. Usb driver da Vcom I have installed.
tablet: x-302 of Dragon - h701
Android 4.4.2 kernel 3 April 67
Tested on Windows 7 32bit, Windows 10 64bit (I also tried compactibility mode).
Standard drivers are installed. The tablet normally communicate, install apk using adb, run and Debug android/Xamarin applications using Visual Studio. This is all OK. If you think MediaTek USB VCOM drivers, so you've got installed:
MediaTek DA USB VCOM (Android) (COM18)
MediaTek Preloader USB VCOM (Android) (COM19)
MediaTek USB Port (Android) (COM22)
MTK USB Debug Port (COM20)
MTK USB Modem Port (COM21)
I had to allow installation of unsigned drivers, and then writes were installed OK. But device has warning "This device can not start. (Code 10). I tried different ways to install or other version, but always writes this warning. However, on the forum, I found it's not a problem. SP Flash tool may work...
