This error message is triggered by the phone's toolkit application, or possibly a SIM card fault.
If you are constantly getting the “Unfortunately the process.com.android.phone has stopped” error, try the following methods to fix it first:
1. CLEAR CACHE AND DATA OF THE PHONE APP
To access this option, go to Settings. Then, select Apps. Tap the All tab so that all the apps of your device will be displayed in a column. Scroll down until you see “Phone” or an option similar to it. Tap it, followed by selecting the “Clear Cache” option. If the problem persists, repeat the steps and include “Clear Data” in your actions. Reboot your phone for the changes to take effect.
2. CLEAR CACHE AND DATA OF THE SIM TOOLKIT
Repeat the steps shown above. But this time, choose SIM toolkit from the list of apps under the All tab.
3. FIX USING CUSTOM RECOVERY
Install the latest AROMA file manager, which can be found in the XDA website. Use it to delete the cache or temporary folder of “Phone” as well as the SIM toolkit app. Then reboot your device for the changes to take effect.
Let me know how it works out for you.

Ok, then try wiping the cache partition of the phone (your data will remain safe):
Turn the phone off by holding the Power button. Then press and hold the following key combination: Power, Volume + , and Home buttons.
If your phone vibrates once, release the Power button, but keep the other two keys from the key combination pressed until a menu appears on the display. Here you can now use the volume button to select "Wipe Cache Partition". Confirm with the Power button to delete the cache. Then mark "Reboot phone" to reboot your phone. Finish!
The error should no longer appear.
Ok, please try the following reset on the Sharp Aquos Crystal:
1. Press the Power button, until your phone is off.
2. Then press and hold the Volume Down key for about 5 seconds.
3. While still holding Volume Down, hold down Power button for a short while.
4. Release the keys when the Sharp logo appears on the screen.
5. Afterwards from the menu on your screen choose option "wipe data/factory reset" using Volume buttons to scroll options, and Power button to confirm operation.
6. Then accept option "Yes -- delete all user data".
7. After that select "reboot system now".
Are you doing this when the phone is turned OFF?
Ok, I'm not sure why it is not working for you.

While I understand the previous tech provided instructions I also understand resetting using the buttons on the phone is all about timing and it can be tricky. I'm providing a link to a YouTube video you might find useful in helping you factory reset the device. Let me know if this works for you!
To select wipe data/cache you use the volume up/down buttons to highlight it, then press power button once to select it. Is that not working for you?
Just a little confused. So were you able to select WIPE factory reset?
