How to capture screenshot on KaiOS device (Nokia 8110 4G)

Question

Does anyone know how to capture screenshot on Nokia 8110 4G (KaiOS)?

Answer 1

You may follow these steps to get screenshot via Firefox WebIDE.

1. On the device - dial *#*#33284#*#* to enable developer mode. There will be a bug icon on the status bar.
2. Download Firefox 58.
3. [Important] Disable your internet access, this is to prevent Firefox got updated to a newer version which might break the WebIDE functionality.
4. Launch Firefox 58 and disable auto update.
5. Resume your internet access.
6. Launch WebIDE in Tools > Web Developer > WebIDE.
7. Restart the WebIDE (because the ADB helper would be downloaded automatically, and need to restart it to take effect.)
8. Now you should be able to see Nokia 8110 detected under "USB devices" at the right panel. (if not, see below)
9. Click the device, "Nokia 8110", and then click Screenshot.

See here for a sample screenshot.

Troubleshooting if you failed to see Nokia 8110 detected:

1. I found it might fail if your Firefox got updated to a newer version automatically, in this case you might need to leverage creating new profile to start over again, see here for details.
2. If the Firefox version stays correctly at 58 but after you click the device, it shows an error saying "Failed to connect", try to reboot the phone and also restart the WebIDE as this post suggested.

EDIT: Yes it is - Joelbert W's answer worked and makes the other responses a bit silly by comparison, just * and # together :-)

Unfortunately, it is currently not possible :-(
