#37567 Use a crystal controlled USBRxTx converter , if you want more reliable loads..
8 out of 10 of my FT232RL adapters would fail FW loads ,but short transmissions work fine, making you think your

#69746 I had this same error message - I really thought it might be a cabling/power problem. I tried editing, it helped a little but was still unable to flash it.

Updated esptool to the latest and it worked right away! My old worked fine flashing other builds but wouldn't load nocemcu firmware.
