LYF Jio F300B is a Qualcomm chipset-enabled feature phone from Reliance Jio. The handset runs on Kai OS and has dual-SIM support, including some of the connectivity options to run the internet. If you’re using this handset and want to install the stock firmware, check out this article as we’ve provided the LYF Jio F300B Flash File (Stock ROM Guide) here with all the necessary info.
It’s quite unexpected for a device to manually flash the stock firmware again due to some error or software-related issues. As the device has a lower hardware specification, it’s possible to get slow in performance easily or bricking or any software glitch. Therefore, flashing the Stock ROM again on your device can fix all the issues completely.
