So I built a solar meshtastic node out of a RAK19007 it worked fine for a few weeks, and then went offline. I plugged it into my pc and it kept making the usb disconnect sound ever few seconds. I was running the stable firmware but I could still get it into DFU mode with a double press of the rst, so I do that and reflash, reboots and does the same thing, I tried different firmwares and couldn’t get anything to work so I figured I burned it out some way. Flashed a 19003 I had lying around, got it all configured and setup over usb power, and walked away for the day with it plugged into the usb on the computer. Came back to the same issues with boot loops. Tried flashing it again running it on it’s own battery instead of usb power. I can still get both of these mounted and flash via the USB so I don’t feel like it’s a voltage regulator that got burned out or anything. Curious if anyone has ideas on the next thing to inspect to try to locate how this keeps happening.
Welcome to the forum @DevoCut
We are not developing or maintaining the Meshtastic firmware. Our support for it is limited.
If your core module is a RAK4631, try to flash the “Meshtastic_nRF52_factory_erase_v2.uf2” to reset the device to factory settings. Then try to flash the Meshtastic firmware.
If that doesn’t help, flash the attached WisBlock Hardware Tester firmware (not Meshtastic), connect over USB and a serial terminal and share the log output here.
The WisBlock Hardware Tester checks essential parts of the WisBlock and gives the results over the log output.

thank you so much this is what I was looking for, I haven’t messed too much with the nRF52s so I wasn’t sure how to validate the hardware
