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)
[HINT]:
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
Build ALPS.KK1.MP1.V2.11
Tested on Windows 7 32bit, Windows 10 64bit (I also tried compactibility mode).
UPDATE
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...
I finally discovered that the problem was in the path to download agent, where was the Chinese characters for example :
**x-302 NEW firmware \ 线 刷 工具 和 驱动 \ mt65xx preloader 驱动 **
I just retype to :
**x-302 NEW firmware\Flash\mt65xx preloader**
and then it works correctly and retrieve the download agent. In all the tutorials I could see that the used path with Chinese characteristics and it worked. However, in my case not.
