I have a problem with my Windows Phone. There is a new software update for my phone and for that I need to have some free space in my phone but I have already 900 MB and I've tried also to reset my phone and it stil doesn't work. It sais: It cannot be opened and I have an error code:800710fe. Do some of you know how I can Update my phone and why it doesn't work?? :s
It seems that a lot of HTC-8S phones faced this problem. The error code
800710fe occurs mainly due to lack of memory in the device. Poor Network connectivity can also be a reason.
As @Southgarden116 said in comments, most users said that the update installed when they had a free space of 700MB or above. However some users have also reported that a free space of 1Gb allowed them to install updates.
So make sure you have atleast 1Gb of space before installing the update.
Note : Hard resetting the phone and then updating fixed the problem for many users. Since you have tried that, I am adding it as a note.
