Chuwi HI8SE Stock ROM Firmware

I can’t find the stock rom for HI8SE. Please, send links for firmware.

How can I flash this ROM? I reset my tablet and I forgot my google account to unlock it…

You need to flash it via SP Flash Tool like any other device with MTK processor.
The link above has only drivers and a flash tool, so you also need to download the firmware

Where are USB drivers for windows for this Mediatek processor? Chuwi hi8SE uses MT8735 chipset
