I flashed my Libra H2O with a different version of kobopatch than the base version that was installed.

Bricked! (softbricked?)
It would turn on and show the home screen but would restart any time I touched the screen.
I was unable to connect to PC and load a new KoboRoot.tgz file to fix it since it restarted when I touched the connect button after plugging it in. I tried the reset combination--pressing power button while holding a page-turn button--but it wasn't actually turning off with the power button, just restarting, so reset didn't work.
Finally, I figured I'd let the battery drain--maybe it'll do a shutdown on low battery, then I could use the button combination to reset it. I left the Libra H2O on overnight with a weight on one of the buttons, the screen stayed on and drained the battery.
In the morning, I plugged it in and tried holding power and a page-turn button and *BAM* it went through the reset process, came back on and was responsive again!

Unbricked! (un-softbricked?)
Sharing to see if anyone else has had an experience like this or saved their Libra H2O in a similar way. Thanks for reading.
