Hi Kenneth,

I still got error by installing a newer version of nRF command tool. The older one is 8.5.0 installed during nRFgo installation.

D:\>nrfjprog --version
nrfjprog version: 10.12.1
JLinkARM.dll version: 6.88a

D:\>nrfjprog --recover
ERROR: JLinkARM DLL reported an error. Try again. If error condition
ERROR: persists, run the same command again with argument --log, contact Nordic
ERROR: Semiconductor and provide the generated log.log file to them.

D:\>nrfjprog --recover --log d:\
ERROR: Low voltage detected at the target. Please make sure the device is
ERROR: properly supplied.

I got 3.49V from VREG.

BTW, My thingy52 's VDD is 0V and VDD_PWR_CTRL is low. Is it correct?

attached the log file for your reference.

Hi,

Any SEGGER j-link should be able to recover the thingy:52. You may try to install the latest nRF command line tools, and run from command line: nrfjprog --recover

Make sure to connect SWDCLK, SWDIO, GND and VDD.

You may try to double check that the reset pin is logic high, if not connect, then try to connect it to VDD to ensure it's not stuck in a hard reset.
