Ok, so that log looks good. However, that confirms that indeed you have a corrupt file on your sdcard-ext. SIGH. Without being able to pull it and recopy the update zip over to it, this is going to be rather difficult. Please tell me you still have the 238 update on your sdcard-ext? If so, I can fix this. If not....I won't be able to without you being able to write to the sdcard from another device.
