If you pulled the battery before it finished then it may have bricked the device. This can also be caused by copying the firmware to the SD card and having it get corrupted by a low quality SD card or flashing and having the SD card disconnect by any slight movements. You can keep trying, but I think something happened during the process, maybe be all the file moving around on your SD card could have made it not stable and then flashed a corrupted firmware.
