Finally managed to update, Dudu7 on Wi-Fi doesnt seems to want to start downloading the update. So i tried local update instead, Checksum failed, downloaded3 times, all the same. Tried to extract the 7z file in the root folder, still doesnt work.
Finally, just click download with SIM/Hotspot and it started downloading. Checksum still failed, went ahead to update and it was totally fine
Everything is working better than before except(some) my A/C settings not syncing with the screen(not sure if it's a Canbus thing or a DuduOS thing). Can't attached the video here to help understand the(minor) issue
