Hi, unfortunately, there is no firmware recovery for M7300, If your device fails to boot up, here are some troubleshooting steps you can try:
1. Reset the MiFi device: Hold the reset hole for approximately 10 seconds.
2. Remove the battery, reinsert it, and attempt to turn on the device again.

If it is still the same after that, you will need to contact the retailer or local support team to check the warranty.
