Well looking at situation I think you havr to root your phone in your computer. To achieve the same you have to install busybox, z4root, titanium backup on your computer. You can find the same from the internet. Now install z4root on your computer and run the same. It will allow you to make a permanent root. Now install busybox and titanium backup. Well titanium backup will help you to restore and back up the data.
Now restart your phone.
Now download Wonder machine and install the same. Once it is installed connect your phone and computer. Male sure that USB debugging is enabled in your phone.
Now launch DWM and select the desired .apk file from your computer and install the same on your phone.
I hope above mentioned information will help you out.

Well I am suggesting a software that you can use to back up data from the SD card. You can download es file explorer from the internet. To back up phone book use the following. In phone book menu you have to press Backup or Export Contacts now choose the SD card. By doing this all the information will back up into .vcf file. Once the update process is completed you can restore the back up.
