I got a raspberry pi 3 b+ for Christmas and yesterday whilst installing a Pi Hat's Software (Rasp.io Duino) it just flat out died after showing that there was an under-voltage, even though I was using a 5.2V 9W 1.8A Amazon Alexa Power Adaptor(I am now using an IPAD 10W 5.1V 2.1A Power Adapter) , It was using BerryBoot with Raspbian and Retropie and it now uses NOOBS but it just shows the PWR LED and no ACT light activity, I've read this means that it can't read anything off the sd card but this sd card works perfectly as I had to put NOOBS onto it. This also happened with a raspberry pi 2 that I had BTW There also is 3v Power Output coming off the GPIO so it can't be this:Raspberry Pi Forum Post
I have tried to flash the sd card with the latest image of raspbian and Etcher and it still shows the same symptoms
After a while, the chips get warmer but not enough the chips actually doing anything
It does not boot anymore and I don't see any rainbow screen at all
Sorry if I'm a bit short, I'm just stressed with this situation
Edit: Now with a new rpi 3b+ the same thing has happened, but I have some extra info, the pi's 5v power is working but there seems to be no 3v3 coming in on the gpio, once again the red light is on but no green light and the I found it happened after shorting the 5v and ground pins by accident
I have just realised that i have contradicted myself :-/
now uses NOOBS
- did you flash a NOOBS image onto an SD card? if so, how? -This also happened with a raspberry pi 2 that I had BTW
did you fix that? – Jaromanda X Jan 05 '19 at 08:23
