Wrecked my RPi 3B+ boot is looping now.

Dear forummers,

It is not Domoticz, but more the Raspberry Pi that is used to run domoticz.

I hope there is a Raspberry Guru out there to help me. I did the following commands

Code: Select all

sudo apt-get update
sudo apt-get full-upgrade
sudo rpi-update
sudo reboot now
The rpi did not boot but appears to be in a boot lopping, starting over and over again.
It is a headless Pi so I connected a screen and keyboard. The last thing I see is polkit.servce just below the RPi logo and the flash a blue-screen and starting again.
Flashed a new SD-card with the Raspberry Pi Imager, used this card to boot but no change. Is the Pi really wrecked? Who can help?

HI @McMellow.

Did you already try: https://www.raspberrypi.org/documentati ... -update.md?

If so, have a look at this Youtube movie: https://www.youtube.com/watch?v=aWYPVN2pekE

Yes, I did this, but it did not solve my problem. But also with a fresh clean Buster the RPi is in boot looping.

I can try this, but I have to copy the image back on another SD card. Not available yet.

Huh?

Did you check the raspberrypi forum as well?
And how is it when you prepare an SD card with NOOBS?

Yes I did, I am searching since monday all over internet.

When I put this card in an older RPi 2B it boots like a charm.
So what is wrong with the card? Does a 3B+ uses other files then a 2B to boot? Is this an fstab problem?
And how is it when you prepare an SD card with NOOBS?
Can do that, what is the advantage of NOOBS (Never used it before.)

Hi, @McMellow,

Perhaps you can look to this thread as well: https://www.raspberrypi.org/forums/view ... 28&t=58151@

You can check the 3V3 voltage. If this has gone, I think you have to contact your supplier.

Regards

Hi folks, thanks for your support so far.
@HvdW I did the init=/bin/sh in the cmdline.txt There is no problems with the fstab file. No change, still a looping boot.
Haven't created a NOOBs sd-card yet. Have no spare cards left.

@FireWizard Checked the 3V3 value. This is OK. Studying at the https://www.raspberrypi.org/forums/view ... 28&t=58151 topic, this takes some more time.

Still wondering, I understand there is no flash memory at all on the RPi. How can it have boot problems with a brand new installed Buster?

[SOLVED] Wrecked my RPi 3B+ boot is looping now.

Finaly!! It boots (headles) again, altough it is not very stable. Fortunately, I ordered a new RPi 3B+ so my Domomticz is up and running again.

After the looking at the fstab file and studying the https://www.raspberrypi.org/forums/view ... 28&t=58151 topic, I realized the 5V power supply is an issue. Attaching a keyboard and a mouse might consume to much power to get the RPi booting OK.

It is a more delicate board then I thought at first.

Everybody thanks again for all your effort and pointing me to right direction
