RPI4 B - worked for 2 months, nothing changed, now it doesn’t

Sun Oct 20, 2019 6:30 pm

Hello everyone.

I didn’t know how else to find a solution but to posting on here.
I have gone through the "PI is not booting up STICKY", but I cannot pinpoint the cause of my problems.

At the end of August, I have installed the latest version of Rasbian onto my RPI4 B. Everything worked well, up until recently.

Situation:
- RPI sometimes it boots, sometimes it won’t,
- When it won't boot, there is a 4-short-flash green LED going on, that should mean that start*.elf is not found. My question here is, is this even possible if the RPI sometimes boots?,
- Sometimes when it boots, it won't startup the Teamviewer or the Pi-Hole, I cannot ssh into it, but I can ping the IP the router is assigning him (ethernet cable connection),
- Sometimes everything starts up correctly, but after a while, Teamviewer and Pi-Hole go offline, while I'm still able to ping its IP,
- Sometimes it won't even start up after I plug it in the power, but just give a short blink of the RED led.

What have I done:
After countless attempts, I have managed to:

Code: Select all

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get upgrade
pihole -up
The problem persists

Is it possible the PSU has degraded with time or could the problem be somewhere else? I don’t want to buy a new PSU if not necessary.

Thank you for your help!

Try a different Micro SD card.

I use SanDisk Ultra 32GB Class 10 98MB/s Micro SD SDHC.

Would you be so kind as to tell me for a specific card brand that should work, or is only my card that is faulty?

No specific brand. Class 10 is good. Super bargain price means fake card, usually.

Thank you all for your help.

Will try a new SD card and also follow this guide to avoid future mishaps: https://durdle.com/2017/01/04/how-not-t ... s-sd-card/

What are you using for a power supply?
