So i decided to install kali nethunter on my nexus 5 today but something seems to have gone wrong. All the steps were working but then i got to the part of unlocking my phone. after backing up my data i let the installer unlock it and my phone began to reboot. But it is got stuck in a bootloop. It went on for hours so i powered it off and tried again. i cannot boot into CWM recovery mode. no matter what i do it just shows the Google logo with the unlocked icon beneath it and then it does the little animation with the colored circles forever. Please help as my phone is now unusable.
