Hello, I own the Minix X8-H:
1. on YT show you to simultaneously press reset pin and power for 4 seconds, while in PDF is written to hold power for 6 seconds do not write anything about the pin - what are the right steps?
2. In my case it doesn't show how on YT
device ID (HUB1-4 for me doesn't show any line with detected devices), I had a problem with MTP USB drivers, but I solved it and Minix X8-H is correctly visible as an additional device taken up in Win7 64Bit (I used the YT method or 4 seconds I held the pin on reset settings + power); my version USB_Burning_Tool v126.96.36.199_build2
3. I received information that uploading firmware by OTG will not cause data loss - is it true? and how does it work if I upload firmware via USB flash drive from the Update&Backup app by pointing to it file?
