My Nexus 5 has been working pretty well until now. Earlier today I decided to disable lightflow and try the Xposed LED Control module. I installed and rebooted and it seemed to be fine. But then while using the phone shortly after unlocking it it completely froze then rebooted itself. Since then it's been stuck in a bootloop where it gets as far as the boot animation but then freezes for a few seconds and returns to the Google screen again.
I tried power off and back on and tried loading into recovery to see if wiping dalvik + cache might get me as far a boot but when it loads TWRP it asks me for a password (I've never set one nor enabled encryption of any kind) so my only option is to cancel but then it can't mount the partitions to wipe the cache.
I suspect it's the Xposed module I installed that caused this but I can't be sure it's not just coincidental. I haven't done anything else unusual on the phone today.
Is there anything I can do to fix this that won't require a complete factory reset? Is there any way I can at least backup or keep my data? Unfortunately I'm not at a computer where I can run or install ADB but if that would let me save my current setup or data I can do so at home tonight.
