My phone froze and I shut it off and tried to turn it back on but everytime I try to power it back up it says "Phone start-up failed, contact the retailer" I recently updated my phone as well any suggestions?

Have you tried to depress the powerbutton for 8 seconds? Doing this should make it vibrate shortly 3 times. Then the phone should be completely off.

If not, you can give the hard reset a shot, just beware that it will wipe your phone.

Most likely tough, you will have to visit a Nokia care point.

Good luck!

Yep tried to depress the power button, didn't seem to do much. I have no idea what the hard reset is for the E7

Take a quick look at the solution here: /t5/Eseries-and-Communicators/How-do-I-perform-3-4-fingers-HARD-RESET-on-Nokia-E7/m-p/1151491/highli...

Beware though that contacts, messages etc will be deleted upon a correctly and successfully performed reset.

If you don't have a back up and don't want to lose your content straight away, contact a care point and check if they can fix it without deleting anything. It's worth to ask about at least.

Mine does the same occasionally, after Anna update. Nokia support thinks it's a memory chip malfunction.

Also it says SIM card registration failed. It works for most of the time.
