How did you downgrade? By connecting to iTunes?
Did you leave the beta programmer before?
To get help to restore your iPhone:
If you see an error when you update or restore your iPhone, iPad, or iPod - Apple Support
You can certainly try. Make a Genius Bar appointment
to avoid delay. Do not be surprised if they refuse to assist
due to the unauthorized software.

Did you follow the advice provided by Georg Portenkirchner above?
Your favorite search engine may provide some direction.
Per Terms of Use, discussion of hacked iPhone is prohibited.
If you are using software including betas from other websites (not Apple),
you are performing unsupported modifications to the operating
system. Depending on what else was installed/deleted/changed
when you used the beta from other than Apple, recovery
may not be possible.
Solved it by myself by replacing the battery
But did you leave the Beta program before?
I connected with iTunes by shift clicking on update and choosing a downloaded update.
I have used betas before yes
No I didn't delete the beta profile
I get the betas from other websites them apple
So take it to a apple store is the best solution?
