2 years ago ikequan, I have had a couple of issues with this, #1 Make sure the sd card is removed before uploading. #2 I have had issues with certain GPIO pins interfereing with code uploads, disconnect GPIO 4 and possibly 2 prior to uploading, you can reconnect them after the upload is completed.

Last month I purchased 5 boards from the Aliexpress link and being trying to upload sketch but with no success. I did some search found out others are facing the same issue with new products from Xinyuan-LilyGO. The boards I purchased last are still working well. Can someone help figure this issue. I've tried updating all drivers but the problem persists. below are some logs. Thank you.
