My Raspberry pi3 B+ does not boot (new firmware)

by osossomething on Tue Jun 19, 2018 4:41 pm

hi,
this is regarding Order #1777059-0180028111
the pi only booted once to raspberry rainbow screen for a short time and it never booted back. I downloaded the latest firmware with no results at all. the red LED is always on and the screen is blank. I moved the sd card to my raspberry pi zero and it boots without issues

I followed the official installation guide and I have plenty of raspberry Pi devices before. I used a raspberry AC power adaptor and it does not make a difference. I tried this 2 weeks ago and I double checked today. I could upload a video of the whole process

regards

Which specific OS version were you using? Do you have a multimeter we could use for testing?

I used both win 10 and ubuntu 16 to create the sd card. I used latest Noob 2.8 installer and also the latest raspian stretch from 2 days ago. the sd card boot on my raspberry pi zero so I believe the sd card is ok, only the pi3 B+ does not work. yes I have a multi-meter.

here is a video of me debugging the issue

Thanks for the video. Can you check the voltages on the 3.3V and 5V of the GPIO header:

You can just do that with power applied. Not worried about the SD card / booting at this point. Just wondering if it may be power related.

5V pin is measuring 5V but the 3V pin is measuring 8mV

Well, that's no good. Thanks for checking. Let's replace it. Send an email to support@adafruit.com with a link to this thread and they can get you a replacement Pi 3B+.
