Solving Unfortunately the process com.android.phone has stopped IN HTC>>>ANY MODEL
I was in this trouble for 6 days,
I gave mu cellphone to many Repairman And I asked them if any friend of them can fix it please do it.
But nobody with any expensive Boxes couldent to fix.
I got my HTC sensation and I was very sad.
But Abruptly I found a way.
I did my cellphone to SUPER CID with ADB & FASTBOOT before.
Because of that change my phone didnt know my sim card.
Some peoples only get an update and they fall into this problem. I am in IRAN (middle east)
YOU MUST CHANGE YOUR CID TO YOUR AREA.
in HTC Series CID s are here
THIS IS ONLY WAY FOR PERSONS THAT ANY WIPE OR RESET DIDNT WORK FOR THEM.
