If the OS detects that an SD card is corrupt, it may put the card into read only mode automatically. Often this can happen at a low level and you may not be informed that this has happened (depends on the OS). To fix it, generally you need to run a "scan and fix" on the card to fix the corruption, a...

LMFAO! Ok yes I finally get it - took me a while I grabbed the file with "wget https://downloads.raspberrypi.org/raspbian_latest" which just created a file called "raspbian_latest". I assumed it was an image file not a zip and was the author of my own misfortune. Thank you to klricks who pointed it ...

Whilst I haven't (yet) done so for any of my "really old" Pi's I have done so for (a not quite as old) A+ using my P3B, FWIW, notes/screenshots are here: http://www.cpmspectrepi.uk/raspberry_pi/MoinMoinExport/RaspbianJessiePixelPi3B.html Trev. Thanks for this - looks pretty similar to what I did, a...

# 1) Burned the Jessie image onto an 8gb MicroSD card dd bs=4M if=jessie.img of=/dev/sdf # 2) Copied the file back to hard drive and verified the checksum dd bs=4M if=/dev/sdf of=jessie-from-sd.img sha1sum jessie-from-sd.img => e0eeb96e2fa10b3bd4b57454317b06f5d3d09d46 I'm surprised by that! If I co...

As mentioned, the downloaded image MUST be properly unzipped using an unzip utility BEFORE writing the image to the SD card. You can't simply change the filename or directly download to the SD card. The unzipped image is close to 4GB. An 8GB+ SD card is required. dd is a utility for converting file...

Many thanks for the replies - sorry for my slow response, I've been away Looking at the replies, I've obviously glossed over some of the details of what I actually did, making it hard for anyone to offer advice (sorry!). So, in more detail here are the steps I followed (annotated). I am running Fedo...

Hi all, I have an original Raspberry Pi (hardware details below) that has been running the music in my kitchen for the last 3 years plus. Now I want to upgrade it to Raspbian Jessie. So I: 1) Burned the Jessie image onto an 8gb MicroSD card 2) Copied the file back to hard drive and verified the chec...
