Re: SD-CARD size problem

Your responses explaining what you are doing are not very comprehensive and I am not convinced that you are doing things correctly. The SD Card Copier is the tool developed by RPF (spl123) and designed to do exactly what you are asking, so it should just work, even on a NOOBS SD card like yours. So ...

Re: SD-CARD size problem

The new image of your SD card shows that it has expanded correctly. but when I put in the raspberry pi, it is not working. Please define what you mean by "...not working" Does NOOBS load? Can you select your Raspbian OS from it? Did you check the "New Partition UUIDs" box when you used SD Card Copier?

Re: SD-CARD size problem

Why don't you just use the SD card Copier in Raspbian to copy your 8gb card to your 64gb card. It will do all the necessary expanding for you without having to mess with gparted. The thing with NOOBS is that you can't easily muck about with partition sizes because they were set in concrete on the da...

Re: Help! Blacked out screen with rpi-backlight GUI...

Sorry, I assumed if you had access to a terminal, the only terminal that would make sense where you could see what you were typing would be a remote terminal over the network using a Secure Shell (SSH) program like PUTTY from a Windows PC. But you've probably not even enabled that. So I assume you a...

Re: Help! Blacked out screen with rpi-backlight GUI...

It's not a permanent setting, so if you can access a terminal (ssh?), "sudo reboot" should get your screen back again when it re-initialises. If you don't want to reboot, then I think the command to use is something like: sudo sh -c "echo 255>/sys/class/backlight/rpi_backlight/brightness" But I don'...

If you have full or standard Raspbian installation on your SD card, use SD Card Copier from the menu to clone your whole SD card to a new SD card in a USB-SD card adaptor.

Re: how to change the logo boot ?

If you replace NOOBS with PINN, I think it could be done, but I've never tried it. Before executing the main PINN recovery program, a "pinn_init.sh" script (if it exists) will be executed. It was mainly designed to initialise third party displays etc., but you could possibly create your own script t...

Your definition of Class is quite good, but you have not described an Object well. In your example, a SWITCH is a class - a definition or blueprint of what properties/attributes a switch has and what methods/functions it has, i.e what it can do. In this case it represents ALL types of switches, or a...

Re: Newest Noobs version does not boot my Raspberry 3 B

256GB SD cards are formatted as exFAT by default and so are not bootable.
You need to format it as FAT32 first for use with NOOBS. (Not necessary if you are going to use Etcher).

Step 1 is to check your 200GB SD card is not a fake using h2testw or various other SD card testing tools before you go any further. Hopefully it's a good one, but it will save you a lot of grief to confirm this first. Once confirmed, the easiest way to copy your 16GB card is to use the SD Card Copie...

It is aggressive enough for MBR cards. I don't think GPT cards were envisioned at the start of NOOBS. If I am correct in how to handle it, there is no need to nuke the whole card as it will just increase the wear. Just wipe the last 34 or so sectors at the end of the card. You can dd from PINN's rec...

Re: STICKY: PINN - An enhanced version of NOOBS.

Hmm. That's strange. Not seen that before.
If it was a PINN installed OS, then it would have been nice to know which one does this and ensure PINN can undo it in future.

For now I can only suggest wiping out the 2nd GPT header as above. Let us know how you get on.
