DietPi does not boot after patch 144

[cellulosa]

I have just updated diepi with Patch 144 and after rebooting it it won't boot. The SD card now appears unreadable.

Hi, thanks for the report and sorry to hear your having this issue.

Which:

• Device (eg: RPi 3)
• SD card
• Power supply

Also, if you are able to plug in a HDMI cable and monitor, is there anything displayed on the screen (eg: error)? Please attach a photo if you can.

@Fourdee thanks for your reply. Unfortunately I don't have any external monitor, but I can see the Pi not doing anything (it keeps the red light and no other blinking appears). Maybe something happened to the boot partition? When I run fsck it returns Unable to read directory (Input/output error).

Thanks for the info.

This stands out as a possible cause (we recommend official RPi PSU with at least 2A), however, we did experience some issues linked to image corruption on a few of our previous images, that may of caused this to occur over time:
https://github.com/Fourdee/DietPi/issues/719#issuecomment-277533451

This should now be resolved, using our updated image DietPi_v143_RPi-armv6-(Jessie).img.

If you are able to read the following file on partition 2 of the SD card, we can check if the image you used may of been effected:

cat /etc/.dietpi_image_version

@Fourdee thanks for the support.

Running cat /etc/.dietpi_image_version on the Pi returns 142.

I have now downloaded the updated image DietPi_v143_RPi-armv6-(Jessie).img. How do you recommend to proceed to manually update the Pi?

@cellulosa

Running cat /etc/.dietpi_image_version on the Pi returns 142.

Ah yes, so this could be caused by the image, apologies for that, although, still cant rule out PSU.

I have now downloaded the updated image DietPi_v143_RPi-armv6-(Jessie).img. How do you recommend to proceed to manually update the Pi?

For fresh installations, DietPi updates automatically during 1st run to latest version.

I have just updated diepi with Patch 144 and after rebooting it it won't boot. The SD card now appears unreadable.

If indeed the SD card is unreadable, and no info is available on HDMI output during boot, a fresh install is the only option.

We could attempt to recover user data (eg: nextcloud files etc) from your previous installation (if its critical), which software did you install, and was a USB drive used?

[cellulosa]

@Fourdee it's ok I will just do a fresh install. Thanks for your help!

@Fourdee I have now bought the Raspberry Pi Official Universal Power Supply Unit and re-formatted the SD drive with the updated image DietPi_v143_RPi-armv6-(Jessie).img. However, after the first reboot (after updates) the Pi does not boot anymore. Still something wrong after patch 144:

 (...)
 
 [Ok] Patch 144 completed

 DietPi-Update
───────────────────
 Mode: Completed
 Please wait...

 [Info] Current Version : 144
 [Info] Server Version  : 144
 [Ok] Update completed

Please reboot your system now, using the command reboot

[Fourdee]

Before writing the image, lets also complete a full format on the SD card:

• download SD formatter https://www.sdcard.org/downloads/formatter_4/eula_windows/index.html
• Extract and Run
• Goto options, and select the following
  
• Ensure correct drive is selected for card, then format (This may take 10-30 minutes depending on write speed)

The above will write zero to all cells on the SD card (essentially refresh/reset). Once completed, write the DietPi image.

@Fourdee

Thank you. By following your process and formatting the SD cart and then installing the updated RPi image it all worked.

I suffered a booting issue with a brand new v144 image burn and boot installation on a RPi2.
Burned the image to an SD card, started configuring it, used for a while, and after that the system didn't boot (just a few green led indications of storage being read, but no display on HDMI so I don't know where the system stands up, as no FTP either)

I removed the the SD card and analyzed it. The FAT partition seems OK (no SDcard block errors, all files seem present including /dietpi), but didn't proceed to analyze the linux type 83 partition (I've just looked for another SD card and reinstalled everything, now RPi boots OK).

Anything you want me to check on the offending SD card?

[WolfganP]

@Fourdee After having issues with booting again after a reboot (RPi2 read the SDcard for several seconds and then nothing, not even reach initializing the HDMI display for further troubleshooting), I analyzed the SDcard and everything on the FAT partition seems OK, but I can't open the rootfs partition on a PC. Is it an standard ext4 partition or did you protect/disguise it somehow?
Thx.

[Fourdee]

@WolfganP

but I can't open the rootfs partition on a PC. Is it an standard ext4 partition or did you protect/disguise it somehow?

All our images use a standard ext4 partition on partition 2. If your system supports ext4, it should be visible. If not, it sounds like a failed image write or unstable SD card.

Have you tried: https://github.com/Fourdee/DietPi/issues/769#issuecomment-283030267 (or dd if=/dev/zero of=dev/sdCARD) to full format SD card prior to image write?
