I have Kyocera DuraForce Ultra 5G, and it's locked to Verizon.
contacted their tech support yesterday, they told me 60 days after purchase it will be unlocked.
Didn't find solution to unlock it earlier
For those who are having trouble applying a FOTA on the DuraForce, check /cache/fota/xyz_fotalog_123.dat It's a text file that contains a lot of really good info on what is going on during a FOTA. Including errors. Keep a look out for signature mismatch errors.
I had errors with the following files. Took me a few tries to get the OTA applied as each attempt resulted in one error.
I've used it a few times over the last year and can only complain it does a sloppier job compared to SuperSU. Every pre-canned root wants to crap all over /system and none is better than the other so long as you get the su binary in a working state IMHO. I know Kingo is harder to clean up after than SuperSU / others but it's a hell of a lot easier to just use Kingo to root and cleanup after. Stacking root exploits and similar like Kingo is doing is a huge PITA and best left to those specializing in such things.
