Hi hope someone can help me with this Please.

I have Kindle Touch and I upgrade into Version 5.1.0
Know the font on the main screen are so small I need glasses to read it
I cannot turn in off into sleep mode
and
if I try to charge the Kindle I get this error
Currently your Kindle is not charging
the light is yellow

before I upgrade the battery was in 50%

I think the version before was 5.0.1
I cannot reinstall 5.1.0 Update your Kindle is gray

if I try Social Network I get error
Unable to start Application

hard restart work but don't fix this
reset in the menu and Reset Device don't fix this

it is not jailbreak ,

Regards
