Q) The basic question all are asking is how to download the general release of ios 10 ,when you are on beta profile .?
A) Let me make a thing clear the GM version and the general release are the same. Pls check the version no. 10.0.1.
Moreover If you wish to opt out of beta and download the general version,then go to your settings and delete your beta profile and restart. After that unenroll your device from the apple beta page.
Now connect your phone via itunes and press the sleep/wake button with the home button until you see the apple logo. After that just restore your phone to ios 9.3.5. After successful completion you can then go into your settings and hit the update button and can get the ios 10 like general public..Now the brick problem is also solved.
That`s all folks., Enjoy,
PS: Take full backup before restoring to ios 9.3.5
