Unfortunately a fix for the bug I found in RC9 while rewriting Heimdall which I was waiting for wasn’t included in RC10 or the now released RC11.
I do want to make a first version of Heimdall available to you so I made a temporary workaround for the bug.
So, if you feel comfortable running an app from the cli head over to Heimdall Alpha-V2 on Github and grab your copy.
If you find a bug, Please report it on Github so I have a good overview and you can keep track of progress.
Any comments/suggestions on the UI/UX can also be posted there.
