My RPi 3B is working again. :-)
« on: October 07, 2020, 11:31:14 am »
So, one of my RPi's 3B quit working a few months ago.  It would no longer boot up any of the SD cards that I have a RPi OS, on.  The red power led would light but the activity led was not blinking.

I had done a Google search of the problem but did not find much.
Today, I thought of doing a search on Youtube and a number of video listings came up.

The second video that I watched was the charm.

The fix was to just pull up on the ribbon tab, on the opposite side of the circuit board above the SD card holder, and reset back in place.   The RPi is now booting Rasbian, just fine.  Yeah! :-)

I had the same symptoms on my Raspberry Pi 3 so I'll have to give this a try, too, if there is a ribbon cable on it. I haven't checked. Thanks for the tip, Bill.

Your tip brought my Raspberry Pi back to life. At least it booted. The SD card I have is corrupted so I have to install a new version of the Raspberry Pi OS. Doing that now. I'll let you know how it goes. Thanks for the tip!

To continue, while it did boot after using the tip, it exited with a kernel panic which is what led me to believe it was a corrupted SD card now that was the problem. I wasn't able to get it to boot after that.

I had to switch SD cards and I got the same error, just a red light. So I wiped the SD card using GParted and started over. I performed the suggested tip. But I don't remember if that was what fixed this time or that I re-flashed the EEPROM, something the Raspberry Pi website recommended when only the red LED comes and the screen is blank.

Btw, you can re-flash it by using the EEPROM option in the menu that comes up after the SD card is imaged. But the website mentions it's for the Raspberry Pi 4. I was worried I had bricked it but it worked. Not sure if it actually re-flashed it or didn't do anything.

Either way, it booted the Raspberry OS and works fine, for now.

Excellent.  Nice to know that a RPi 3 can possibly be recovered, when it fails to boot.  Thanks for your info, Jason.

No, thank you, you for giving me the tip. I'm not sure what I'm going to do with the RPi 3 yet. Now that I'm using only a single monitor, off the laptop, perhaps I'll use it so I can look at tutorials and follow them on the laptop. Glad it's not a write-off.
