Great work abhimortal. It is working for me with an airtel sim card. But I have another requirement. Can I read the sms coming to this sim card using an app like Jio4GVoice for airtel sim card ?

Unlocked Firmware for JioFi 3 JMR540 & JMR541

Disclaimer
I am not responsible for any kind of damage to your device.
Use this firmware at your own risk
Post is for educational purpose only.


ONLY FOR JMR 540 & JMR 541


I was able to dump and reverse engineer JioFi 3's firmware to see if I can unlock the SIM restrictions. JioFi 3 is designed by Foxconn it uses generic firmware. Unlocking took time though. Tested with Vi, Airtel.

UPDATE 17-10-21: Jio pushed a firmware update which is locking boot loader. If your device is not updated yet it is advised to re-flash your firmware with patched image given below which basically disables auto updates. If you're already locked out, currently there's no easy fix for that.

If you haven't used your device from a long time or you're still on lower or equal version than below it is advised not to use JioFi with SIM, flash this firmware first if you want to test SIM unlock.




Guide

Make sure you're on same or lower firmware version
  • JMR 540 - FXN_JMR540_R6.16
  • JMR 541 - FXN_JMR541_R3.10
If not please use the device for sometime it'll autoupdate.


1. Locate your device model and download the respective Firmware and extract it to a known location


2. Install drivers and tools (skip if already installed)

  • Install Fastboot drivers ( google it for mac and linux it's easy to find)
  • Install Fastboot ( google it for mac and linux it's easy to find)

3. Prepare device

  • Remove battery from JioFi 3
  • Locate reset pin hole button
  • Lay down JioFi 3
  • Use Paper Clip / SIM Ejector Tool to press button inside (using sharp object is not recommended)
  • Keep pressing button down and insert USB cable
  • Release button as soon as all the LEDs in Display turns RED. This means device is in boot loader mode

4. Flashing Unlocked Firmware

  • Open adb and fastboot tools terminal
  • Enter following to check if device is connected

  • fastboot devices

  • It will return something like this
  • baxxxxx fastboot

  • This means device is connected. If your device doesn't show up here please check drivers in Device manager
  • Now first erase the system partition

  • fastboot erase system

  • It will return something like this
  • erasing 'system'... OKAY [ 1.104s] finished. total time: 1.105s

  • Now flash the firmware
  • fastboot flash system "D:\system.img" ( replace path )

  • It should return something like this
  • sending 'system' (34306 KB)... OKAY [ 1.276s] writing 'system'... OKAY [ 9.462s] finished. total time: 10.741s

  • Now send reboot command to device
  • fastboot reboot

  • You'll notice device will reboot normally now you can unplug the cable.

Congratulations your device is now unlocked and you can reinsert battery and another SIM for testing.

Firmware will take long time than usual to boot do not panic.

4. Changing APN
  • Insert SIM connect with JioFi 3 wait it to intialize
  • Open Web UI from browser (http://jiofi.local.html/)
  • Now login (default username/pwd is administrator/administrator)
  • In Network Tab you'll find setting for changing APN
  • Put it on manual and enter "internet" as APN (without quotes)
  • Hit apply/save device will reboot again automatically and it'll auto connect
  • Just wait patience is the key here it'll connect.

If something goes WRONG or you want to UNDO you can re flash original firmware which is provided in this post.


Original backup




FAQs

  1. Q. My device is not visible in fastboot devices
    A. Confirm driver installation a faulty cable can also be the issue.
    .
  2. Q. Everything went well but still no changes in dashboard
    A. After successful flash if you still don't see the changes your device is probably booting from recovery partition. Try flashing recovery partition by
    fastboot erase recoveryfs
    fastboot flash recoveryfs "D:\system.img"
    .


  3. Q. After resetting device from pin hole button it shows INVALID SIM.
    A. This is supposed to happen just reboot the device it'll work again.
    .
  4. Q. Can I undo all this and get back to original firmware
    A. Yes just flash the original firmware provided in post and reset the device.
    .
  5. Q. I 'accidentally' flashed my recovery and boot partition
    A. Well accidentally I've backed up recovery and boot download from below

    1.
    JMR540_boot_recovery.rar
    2. JMR541_boot_recovery.rar
    .
  6. Q. FAILED: (remote: Image is locked) issue while erasing/flashing image
    A. Jio recently pushed an firmware update which re-locks simlock and bootloader which basically means you can't flash unsigned/custom firmware. Currently there is no fix.







Mentions:
Thanks to
Karuppusamy for testing it on JMR541.


What about JioFi 2, 4, 5, 6?
Reverse Engineering takes lot of time and coffee. Until I get physical access to device I won't be able to unlock it. I'm constantly searching them on OLX as soon as I get hands on I'll surely try to RE and unlock it. I'll update the same here if there is no update here at the time of your reading then I haven't got the device yet so please don't spam for update hope you understand that I don't get anything by doing these things, I do it for liberation of locked hardware to meet it's real destiny and of course for the people. I also have a day job so no I cannot guide or teach you, hope you understand why.

I just bought a new JMR541 and haven't yet connected to the internet with it. Can I directly flash the custom firmware or do I have to update the router to a specific factory firmware?

    Yes as i flashed recovey and system with same patched. After new fix by jio firmware my wifi was getting disabled after some time.
    I think because of flashing both partitions my device didnt get locked and i was able to flash re-patched version.

    bro is unlocking more 4g bands or manual selection of bands can be done ?
    Totally possible even 3G but it can't be done through WebUI it'll requires shell access.

    after knowing from u guys about recent update pushed by jio my device wasn't updated so i instantly removed the sim and waiting for update from abhi
    For Jio --- guys u have stopped selling this or selling in 5k -6k like black marketing and nor your devices are built well, if someone has unlocked it what's the problem you have not pushed any update to other models which were previously unlocked now those devices are being sold at higher prices. I am happy that airtel and vi are here otherwise your greediness to capture everything would have led us to ______ no words to describe'
    You can install and test patched firmware auto updates are patched and disabled now, link is in original post. Devices which are already updated, there is no easy fix for them right now. Jio loves their users aww ( throws JioFi in space ).

    Working fine but only one issue that it is auto updating to official firmware within couple of days and we need to redo the entire process again.
    Any way to stop the auto update of firmware
