Main POWER or USB?


I have a brand new Xtool D1 and it worked great for a week. Then today in the middle of a job it started connecting/disconnecting rapidly from USB and now it barely connects at all. I can’t find much info online regarding the motherboard.
Does anyone know if the little blue LED is a power or coms light? Next to TF card.
it only flashes when Power on or power off now… it used to be on all the time.

any help is gratefully received. I have emailed but was wondering if anyone has any ideas…


You can try

Also, you might try another USB cable. It could be a bad connection; that happens a lot.

Thanks for your time,
