While I am fairly certain the structure of an intel hex file prevents this from being an issue, it would be nice to under stand how this happens.\r\n\r\nEncode to database:\r\n```\r\nfile_name = file_path.split('/')[-1]\r\nwith open(file_path, 'rb') as file:\r\n    md5 = hashlib.md5(\r\n        file.read()\r\n    ).hexdigest()\r\nintel_hex = IntelHex()\r\nintel_hex.loadhex(file_path)\r\nif image_type.lower() in ['mfg', 'manufacturing']:\r\n    self.manufacturing_fw = intel_hex.todict()\r\n    self.manufacturing_fw_name = file_name\r\n    self.manufacturing_md5 = md5\r\n```\r\n\r\nDecode From database:\r\n```\r\nif image_type.lower() in ['mfg', 'manufacturing']:\r\n    output_file_name = f'{out_path}/{self.part_number}-{self.manufacturing_fw_name}'\r\n    firmware_data = self.manufacturing_fw\r\n\r\ndata = {}\r\nfor key, value in firmware_data.items():\r\n    if key != 'start_addr':\r\n        key = int(key)\r\n    data[key] = value\r\n\r\nintel_hex = IntelHex()\r\nintel_hex.fromdict(data)\r\nintel_hex.write_hex_file(output_file_name)\r\n```\r\n\r\nI need to add these lines upon export to re-arrange the lines to get the exported file to match the original exactly.\r\nNot efficient or the minimum solution, but it works with everything I have tested so far.\r\n```\r\nfile = open(output_file_name, 'r')\r\nlines = file.readlines()\r\nfile.close()\r\noutput = open(output_file_name, 'w')\r\ntotal_lines = len(lines)\r\nlast_line = lines[-1]\r\nlines.append(lines[-1])\r\nlines[0], lines[total_lines-1] = lines[total_lines-1], lines[0]\r\nlines.append(last_line)\r\nfor line in lines[1:-1]:\r\n    output.write(line)\r\noutput.close()\r\n```\r\n\r\nI appreciate any help with this!","author":{"url":"https://github.com/LukeGary462","@type":"Person","name":"LukeGary462"},"datePublished":"2020-07-08T15:15:54.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":11},"url":"https://github.com/43/intelhex/issues/43"}
