TC70 Install Failed/ No Access to Fastboot

I have an issue where the GA1 to GA2 install failed and left the device in a limbo state. On boot it informs me that encryption failed and must reboot and loops to this screen infinitely. I can boot in to recovery however when I attempt to re-run it fails again. Assuming the file could have been corrupted I attempt to adb push however it returns No such file or directory for storage/sdcard0 or storage/sdcard1. I then attempt to run adb shell which returns exec '/system/bin/sh' failed: No such file or directory. Again no luck I then attempted to open the full upgrade zip and pull the recovery.img this leads to a issue with bootload being locked. Is it possible to unlock the bootloader or use fastboot on the TC70?
