I just bought a Bee-link GT King Pro and accidentally deleted the sd card with coreELEC on it. Is there any way to recover coreELEC or get another sd card?
Hi Amanda2018 and welcome to the forums.
Follow this guide to setup a new installation to the SD card.
Sorry, you will have to reinstall CoreELEC.
To avoid having to reinstall all your addons in the future, I recommend making a backup once you have everything to your likings.
It depends what you deleted. There is a little fat partition with the squashfs and the kernel and some configs. If you only deleted those there is a chance to get back your data.
Also if you just deleted the partitions and created new ones without data there is a chance to recover.
