Hello, sorry to tell you that we don't have ready-made firmwares of higher version than the original version. But the original firmwares are enough to ensure the printer work normally. If you want to do some revamp on the firmware you can do it youself. Our original firmwares are marlin firmwares. If you want to get the original firmware, please let me know the mainboard of your printer and I will send you the corresponding firmware. Thank you.
