Yes, you read that correctly; here you will find the best working method to unlock JioFi Mobile Router for free. I have been researching the JioFi Mobile Router for the past few days. You are about to learn the most effective method for JioFi Unlock.

Unlocked Firmware for JioFi 3 JMR540 & JMR541

I was able to dump and reverse engineer the JioFi 3 firmware in order to see if I could remove the SIM restrictions. JioFi 3 is manufactured by Foxconn and runs on generic firmware. However, unlocking took some time. Vi and Airtel were tested.

UPDATE 17-10-21: Jio has pushed a firmware update that locks the boot loader. If your device has not yet been updated, it is recommended that you re-flash your firmware with the patched image provided below, which effectively disables auto updates. If you’ve already been locked out, there’s no easy way out.
