Install ROM over STOCK slot Saftstrap 3.75
I'm running CM 12.1 Nightlies on my Bionic and am very happy with it. In trying to squeeze every drop of performance out of this old phone (my daily driver) I would like to remove the stock JB ROM to free up space on my internal storage.
As I understand I need Safestrap v.3.75 because of a locked bootloader, so if another recovery is not possible I am curious if it is possible (worth the risk) to install CM 12.1 over my stock ROM.
Does anybody have experience with this?
