New updates won't install

[eishypalssang]

Hi,

My phone wasn't able to install the first 5.1.1 update and now it won't install the most recent 5.1.1 update(N910VVRU2BPA1).  It's able to download the updates but give me error at the end and it won't install.  I've tried everything.  I really didn't want to factory reset my phone but nothing was working so I have tried that and it still won't install the new update.  I've even wiped cache partition.  What can I do about this?

Thank you all in advance!

I can't even reinstall apps I used to have on this phone.

This whole update thing is literally ruining my life.  I need those apps for work and this is happening in worse possible moment.

I have the Sony Z3v and having the same issue.  Is there a contact number to call for help?
