Hi I need help for a device that has no manufacturer blob to build firmware and no support for twrp. I do have the complete firmware dump and know it is a mtk mt6737t s01 chipset. It has a vhf/uhf radio built in and does not support fingerprint scanner. The most annoying thing is there is a volume knob and not switches so I have a hard time getting controls to work in the bootloader, also everything is in Chinese.
I would like to get this up and running on android 9. I can help fully with development from hardware to testing
