Raspberry pi messed up?

@herb_fargus Wow. I had never used etcher. Thats good to know! I'm a manually-do-every-step-because-im-old-and-dont-want-to-forget guy. I need to get with the times.

@thedatacereal It's not wrong to do things step-by-step, as it can help to locate the error if things go wrong. That said, one can also benefit from tools that do multiple steps for convenience. :)

This is the error code. I have seen it on different topics relating to under-power rewriting the SD card but I’m using the official raspberry pi power cable.

Kernel panic - not syncing: VFS: unable to mount root fs on unknown block(179, 2)

I’ll try using Win32DiskImager and etcher with an unzipped file.

Right, so I downloaded the retopie image from retropie.com/download. Fine. However when I try to extract it (using winRAR) I am told that the file is corrupt. Is this an issue with the image or is it my extractor or...?

@ddoherty958 Try using 7zip or just use Etcher on the compressed file ( I just learned you could do that 😁😁)

@ddoherty958 It says the file is corrupt because it is. Re-download the image and try again.

No, don't do that. That will just write an incomplete image file which might be the cause of the problems.

@ddoherty958 Compare the md5sum checksum on the download page to the checksum of the file. (Just search the web how to do that, there should be plenty of sites explaning it.) Continue only if both checksums are the same.

@clyde

It was successfuly verified. However when u tried to extract it it still said it was corrupt

ddoherty958

The error code is: unexpected end of data.

@darksavior
I've lost count of how many tomes I've done that

@ddoherty958 It extracts fine here with winrar. Im using chrome on my pc. Try a download manager that can resume downloads. Or try a torrent.

ddoherty958

I tried again with 7Zip and got no error codes, bu on first boot it went straight to command prompt! I'll try a few things and get back to you.

You say you are using the official power cable? Do you mean power supply? I suspect your pi may be underpowered if your dc power block isn't supplying enough current to it. I'm not sure what the required/recommended amperage is, but it wouldn't hurt to have at least 2.0 A going into your power cable to the pi...

@gomisensei

The recommended amount is about 2.5A and I just went on PIsupply.com and typed in raspberry pi power lead. The block seems to be fine, I havn't had any issues with the power, just everything else ;)

@ddoherty958 On first boot, the image will resize the installation file system to fill the disk on the card, then reboot. You need to have a little patience and wait for it to finish the operation, then - after the reboot - you'll be presented with the Emulationstation screen.

@mitu

Yes, I just rebooted it and it loaded up fine. Fingers crossed it works this time!
