Mysterious "Installation Failed" and reboots
Sorry for the irrelevant answer to the OP's question but felt a need to point out about aLogCat.

aLogcat seems broken at the moment under JellyBean (due to an additional introduction of permission READ_LOGS required for reading logs). 

Just keep an eye out for the update soon (or flag the developer by starring the issue here). 

If you fancy the alternative, try this version called CatLog found here on github, this has the permission in place to do so.

As for Droidwall, forget about that version - its old and obsoleted in favour of the more updated version AFWall+, the linky to the play store version is contained on the github page, alternative linky to F-Droid Repository here.
