I've recently rooted my phone and I was thinking about adding a custom recovery and ROM. However, my original OS still must be accessed. Is this possible?
When Flashing New ROM onto Device, Can the Original Still Be Used?
Question
Answer
MultiROM should be what you're looking for, though it's only limited to a few of popular devices that support it / has it ported over, e.g. Nexus series, Redmi, etc. Look up in XDA-Developers if your device has a port.
