Without repeating all the information already present in this thread and many others, in a nutshell CR3lite will allow you glitch a corona, albeit it with uncertain/unstable boot times, although quite a few users appear to have had some decent results. If you absolutely want the best possible glitch times for corona then you will have to wait for CR3Pro, which could be weeks/months away, there is no way to tell, it is still in development, you'll know when we know. In the meantime you will benefit greatly from reading all the currently available information on the forum.
