Where to download official Wiko Jerry drivers for ADB/USB connection? I'm failing to find the page with original drivers, I only find third party websites that I don't know if I can trust. The manufacturer website is lacking the drivers (apparently). I'm using Windows 10 and have already the Whole NDK installed.
You just need Mediatek drivers for any phone powered by an MTK chip. Since [all] Wiko devices are powered by Mediatek chips, you can use drivers for Alcatel MTK, or ZTE, etc. 
Go here to download the firmware which contains the flashtool, drivers and instructions.

or here to get the Wiko drivers (VCOM and CDC)
