See bottom of post for my review.
Doesn't work on Volt with CM13, but then again IDGAF.
This really is only good if you don't have a custom recovery, such as TWRP.
I found a Boost
Kyocera Hydro Icon with a cracked (fully functional) screen, got it rooted and removed all bloatware. There
isn't a working custom recovery yet, so now this is how I'm able to flash things to the device without having to use the PC.
I have tried Flashify on the Icon, but it fails due to lack of built-in ability in stock recovery and reboot choices. With
Flashfire it is able to do its intended purpose. It allows different
reboot options that let it function properly
Flashify is a great app, but it should've had additional reboot choices. I know that its more involved that, such as a butt load of programming. To be competitive though, it needs to have an update.
REVIEW
I used Flashfire several times on the Kyocera before leaving this post. It works great. I also flashed an opengapps 4.4. and all things google work fine.
There shouldn't be any reason why this wouldn't work on a stock rooted Volt w/o TWRP.
