PPK2 bricked and firmware update fails

[vofitserov]

I've was able to use brand new PPK2 to make test measurements few days ago and it was working fine. I've connected the unit today and software have issue recognising the device. I unplugged and plugged PPK2 back into USB and it never turned green, blinking fast red. I've followed instructions to short TP34 and ground. The kit shows up in nRF Connect and I click "Yes" to update firmware but device never comes back. I've tried mac and windows and never was able to successfully update the firmware.

Hi,

Which is the version of the nRF Connect for Desktop and the power profiler version.? Did you download the recently updated versions.? Also, please let me know the version of JLink that you are using.

Kind Regards,

Swathy

I have old Mac where I use 3.1.3 version with 3.7 version of nRFConnect and I have Windows where I use the latest version. I've tried to update firmware on both with same results. The nRF Connect states the error and device does not light up green.

Swathy, this was first thing I've tried. The firmware updates starts successfully both on Windows and Mac, the led start flashing rapidly during the update but then device goes back to fast blinking red and never turns green. After the firmware update the software reports different problems depending on the version but Windows reports: "Error while setting up device FD8ECA4121AB: Error: Timeout while waiting for device FD8ECA4121AB to be attached and enumerated".
