Recently I've been googling on how to unlock my jiofi jmr540 device and found nothing.

But I discovered something else. I don't think we need a custom rom to unlock the device. I'm not a expert in these stuff.

Every jiofi device has web UI.

I discovered that every jiofi device have a hidden web UI that is engineer mode.

I didn't find any rom for my device but I found for jmr520 which was in bin format. I opened it using notepad in my pc and discovered that engineer mode does exist in its coding. There is lots of options present in engineer mode like manually selecting network band, choosing between 2g, 3g, and 4g, manual network search, and I also saw some network unlock coding which I couldn't understand by entering unlock code.

Can anyone help to access engineer mode in my device. I think it is also a html just like jiofi.local.html.

It would be really great if someone helped as many jiofi users are still wanting to unlock the device.

My device details are,

Firmware Version: FXN_JMR540_R6.11
Hardware Version: FXN_JMR540_V055
Device manufacturer : Foxconn

How did you get fastboot menu? Can you extract firmware and send it.

I've managed it to unlock this device. Enabled diagnostic mode and adb. Custom firmwares are possible in this devices. Once modified firmware can be flashed via fastboot mode which is easily accessible without any modification.
