New user here, how to flash ROMs?

[mountainbikert]

Hi,

I just got a Beelink GT1 Ultimate with a G912 serial number and stock GT1_313M0 rom but it hangs every 20 minutes, so I want to upgrade the ROM and root if possible. But I don't want to brick my device and I want to know what the best way is to flash the device. Should I do it by micro SD card or do I need the OTG cable (and where to get one)?

Thanks for your help!

for images you can do both ways to flash, its up to you

as usb otg cable it should have on both ends the big connector of usb-sticks (Type A on both sides)

search on google or youtube and you will find how to do it both ways

maybe some OP or Moderator should make a sticky for this since in knowledge& tutorials is nothing ;-)

Moderators should create a stick tread with links, phtos of USB Male A to Male A, and a extensive how to do it, for newbies like me and future users....
