Hello, it sounds like you may have a faulty battery backup for the Real Time Clock. Unfortunately this is something that must be repaired in our lab. I would suggest that you request an RMA, in which you will be provided with an return label to send the item back for repair or replacement. Below you will find links to our RMA form and Warranty policy.
Same issue here. 3S logger ordered on 25/9/18. Sent @support email on 25/10 to no avail. Now also mass storage, compass, gyro look faulty. Got RMA from app's diagnostic, copied on a support request through your onlone contact form. Hope we get an answer at some point.
Hello, I am sorry I do not see an email from you. Would you please resend it? If you feel you would like to send the unit back for repair please visit https://yostlabs.com/support/rma-request/ to apply for an RMA.
thank you for your reply. I'm going to re-send the original msg to your @support email
