[Android Q&A, Help & Troubleshooting] runandhide05:
So... Hear is very clearly what u need to do. But before I tell u I want to make somethings clear.

Root access alone will not make /system rw.

You have to mount system as rw.

Apps that relay on root access will do this for u if they modify the /system which exposed would have.

Also removing/uninstalling /system apps is not ever recommend for many reasons. If there were ever an update you would not be able to apply the update.

You have titanium back up. Use the freeze option instead. This allows u to restore the app if ever needed.

Now on to your issue. Please forgive me as your OP is a bit of a run on and broken English.

From what I can understand (and with a bit of guessing) one of your xposed mods cause a FC of the system UI. Which lead u to hunt down issues in the wrong place (even if u hadnot factory reset clear cache would have done no good)

Xposed is.... OK... But has many fundamental flaws in a nut Shell it replaces a few native .jars with hooks built into them (this in of itself modified files in the /system of which the normal end user has no idea which files so right off the back you will never be able to update your system if ever and OTA comes for it)

Secondly the biggest flaw in exposed... The modules. Way to much trust is given to the creator of said module and many of the modules I inspect have modules active by default. This is a HUGE no no because say a certain aspect of this module does not work with your current rom(version of Android altered by OEM and carrier) well guess what happens... You have just created a device that when it boots it runs that module which causes the system UI to crash and now u can not access or use your phone. And because your rooted but not unlocked (bootloader not carrier unlocked) you have no custom recovery and therefore no way to restore the /system partition of your device... Welcome to your house hold another paper weight brick.

So you or any average Android "tinkerer" thinks (and rightfully so because its says EVERYWHERE a factory reset will restore my phone to like the day I got it) I can restore my phone with a reset. Well that is true to an extent. If you never touched the /system partition of your device a factory reset just erases all data in /data (user data partition) and presto phone is back to new... However the simple act of rooting a device touched the /system to place two files in there. The su binary and the supersuer apk.

Anyways. To continue on. I hope the above info enlightens you to your current issue. You need to restore your /system partiton... How do I do this you ask.. Well IF you had root you could replace every file you modified or touched or removed (with the exact same file that comes preloaded can not be a copy of an apk from the play store and another device that's "close enough")

Each file must be signed from your OEM.

OK so you say well **** I don't have root access any more.

Still not the end of the world. You could fastboot flash (or whatever means of bootloader communication Kyocera uses)

However because your bootloader is locked you can not just flash the /system with anything. It must be an image signed by OEM and or carrier.

And sense most oems do not have just a system img to flash you will need to locate the entire package they flash, and it must be for your EXACT DEVICE if you flash say an AT&T package on your vzw device you will only cause fastboot flash failures due to signing mismatch or worse.

So I leave you with this.

Google

Fastboot OEM files for (insert device name/brand/carrier)

And may I wish u the best of luck
