yes 1.4 is even more unstable than 1.3 you should be able to boot rps using the 1.3 exploit since it still boots the 1.4 homebrew launcher on youre sd
=> About Homebrew Launcher 1.4 : Following some feedbacks we've received during this week-end, it seems that some people are encountering white screens issues trying to run the payload. For many of them, this was fixed by resetting browser's cookies on their WiiU, so if you encounter the same problem, try this solution first. On the other hand and even with a cleaned browser, the problem is still there for few users. While we take a look at this problem, we invite impacted people to run HBL 1.3 instead of 1.4 for the time being, as the bootrate is way better on it.
We apologize for the unconveniance caused.
