Did you install it to a rooted device if not then theres your problem - Your only option now is to perform a system repair using either PCC or SUS found here - For PCC fully switch your phone off then Select Support zone then Update my phone/tablet then in blue select repair my phone/tablet and follow the instructions remember when promted to hold volume down and connect your usb cable - Do not attempt to power on your phone during this time or at any time leading up to connecting it

In that case you need to manually Flash a relock bootloader file then use PCC or SUS or download a stock .ftf file and manually flash using Flashtools

ok and where can i find this file?

[Thommo · Accepted solution]

Best place to find these files are XDA here and look for the stock roms or to relock your bootloader try this here You can Google Flashtool instructions but a good guide is here - Ignore the title as it's the process you need to follow
