Security Warning froze phone white photo transfer

[Susi T]

I was trying to transfer some photos from my phone onto my Mac. A security warning shows up on my phone screen saying:
Security Warning
If you flash this phone with any ROM
that was not officially released by HTC
you take the risk of
releasing your personal and financial
information to unknown sources.

The phone is basically frozen. I can't turn it off, or move to another screen or page. he warning just sits there.

Apparently your Desire 526 has a removable battery. Try pulling the battery, leave it out for several minutes, and then put your phone back together and see if it'll restarts normally.

Edit: Ugh, just noticed the OP is from June.
