Apple has deliberately locked down certain storage areas that the plugins need, which is arguably a good thing in the name of security. Or so they say.  |
I'm not sure what would be entailed in making it work from Kris's end, or if it'd even be possible without major re-architecting but you can get Marvin and Calibre working as expected on iOS 8.4 or below.
You need to jailbreak the phone with TaiG (
http://www.taig.com/en/) which might seem scary but it's perfectly safe. You then need to run Cydia which is a 3rd party application installer that will be installed on your home screen and search for / install "House Arrest Fix" which reverts the file system restrictions to what they were pre-8.3. Keep in mind this makes your iPhone or iPad a bit less secure but it's probably not that big a deal for most people.
Keep in mind this only works with 8.4 and below, the recently released 8.4.1 closes the exploits that allowed jailbreaking. If you are already on the newer release or have used the over-the-air update method to get to 8.4 then you can - for a limited time - restore the firmware to 8.4. I didn't vet these instructions extensively but they look legit (
http://www.iphonehacks.com/2015/08/h...ios-8-4-1.html), the second / faster method is all you should need to do. You're basically just downloading the old firmware from Apple and then using iTunes to restore to the older firmware. This normally doesn't work but there's an intermediate period of time after they release a new firmware where they keep signing the old one. Once that's up it's over and you'll have to wait.
Do not ever, trust a jailbreak or software that purports to jailbreak your phone unless it's given the ok from somewhere like
https://www.reddit.com/r/jailbreak as there tend to be a lot of scams and whatnot once Apple patches the bugs and people get desperate.
