What is Reddit's opinion of Pi SD Card Imager?

You can get an SD card pre-installed with NOOBS which you can use to install Raspbian and then follow the instructions for a manual install of RetroPie at: https://retropie.org.uk/docs/Manual-Installation/.

Alyernatively, you could try Pi SD Card Imager: https://play.google.com/store/apps/details?id=com.redrobe.raspicardimager

If RetroPie isn't available in the app, then install Raspbian Stretch and do a manual install as above.

Let me get it right. So you want to write the Raspberry Pi OS image into an SD card using Chromebook machine?

If yes, the standard method is to use terminal with dd command. You can find tutorials at r/raspberry_pi.

If you want an android app to write image, try this. (but I haven't tested it). https://play.google.com/store/apps/details?id=com.redrobe.raspicardimager&hl=en_US

If RetroPie isn't available in the app, then install Raspbian Stretch and follow the instructions for a manual install at: https://retropie.org.uk/docs/Manual-Installation/.

If you have an Android device, then you can use the Pi SD Card Imager app to write Raspbian to a SD card.

Make sure that it is Raspbian Stretch as Jessie is no longer supported. Also make sure you choose the full desktop image of Raspbian so that you can use the desktop to download roms once RetroPie is installed.

Once you have booted your Pi with Raspbian, you can follow these instructions to install RetroPie: https://retropie.org.uk/docs/Manual-Installation/

Yes, there is an android app to do that:

NOOBS cards can be created without the phone being rooted.

OSMC and your own custom .img need root to work.

I was think this would require a rooted phone, but it appears not - This app has mainly good reviews and was recommended in a raspberry pi forum. It make no difference what the image is. https://play.google.com/store/apps/details?id=com.redrobe.raspicardimager

In theory (I never tried this):

It should be possible to run / install a stock image of Raspbian (aka Raspberry Pi OS) on a USB drive.

Then - running Raspbian - you should be able to flash an image to the mSD card.

or

you can use any Android device with a mSD card slot (I tried this on my Amazon Fire HD tablet and it worked)

download / install or sideload this app:

Haha

I don't know if the SD card has anything preinstalled on it, but you can use an android phone to setup the microSD card for the Pi.

EDIT: I live somewhere that sees temps below 85°F only in the Winter, and then only for a week or two usually. And that is why I mention a fan and others don't.

Maybe someone around has a tablet/phone with mSD slot? Even the cheapest 30$ Amazon tablet should have a mSD slot.

You can flash mSD with android apps like this:

I tried it once (Pi 4 wasn't booting) while I was lazy and sitting outside in the garden. It's not fast but it worked.

You need software that can completely image the SD card. I found this with a quick search. Only certain images can be flashed without root, and the dev recommends a USB-OTG card reader, so no idea if it'll even function with an internal reader.

As far as I know you'll need a PC and a card reader to write the image on the SD card.

However I know there are apps available which can do it from an Android device itself, like https://play.google.com/store/apps/details?id=com.redrobe.raspicardimager I haven't tried this method, but could be a solution.

This is a dumb question but here I go:

My computer does not have the ability to read SD cards, so if I can I'd like to use my android phone to format the SD card. I used this app to get the NOOBS OS onto the SD, but I'm not seeing a way to format it. Is there a way to do this on my phone, without having to buy new electronics?

If your phone has an SD slot, the linked app below can write the card.

Do you happen to have an Android device with an SD slot?

you can use your smartphone if it has a card slot, https://play.google.com/store/apps/details?id=com.redrobe.raspicardimager

or the DD command, i've never tried the ubuntu startup disk maker.
