Steps to backup firmware by hardware hacking method :

1 Open device (jiofi m2s) to find tx rx gnd pins.

2.use "UART to USB" pcb to connect pins to pc ( revers connect tx rx pins )

3 get root shell access !

4 enable adb , backup stock firmware

5 modify stock firmware to unlocked firmware

6 flash unlocked firmware

7 enjoy all network

What city do u live in?
[Upgrading, Modifying and Unlocking] Waishshaikh:
Same here in my JMR540, Vi is not working but Airtel is working perfectly. Because of jiofi support these band Band 3/5/40 i.e. 1800/850/2300. And none of them is used by Vi so not getting connected. Try calling Vi to fix it using pretext that Vi is sim not working in Dongle (say other sim like jio Airtel is working) . Dont tell them it's jiofi. 😆 Tell them dongle is of huawei.

My device after a 1 month of usage automatically go back to its original firmware,

[Upgrading, Modifying and Unlocking] chaitanyakorde:
Thank you very much @abhimortal6 for the hack. I was successfully able to unlock my JMR541 and use Airtel. I came across an issue which I want to share as there may be others having similar issue.

I am using Windows 10 Pro as well as Home (2 different laptops). I installed all the pre-requisite software (ADB & Drivers etc) & connected the device in bootloader mode but it failed to install my device & showed a question mark against it in the Device Manager. I tried reinstalling the drivers quite a few times through different versions of ADB Setup as well.

Also tried to install it via Windows Update but no success. Later, I let the Windows Update check for updates and then to my surprise, an update showed up in Optional Updates for Android Device. I quickly installed it. After installing, it finally detected my device and I was able to complete the process.
[Upgrading, Modifying and Unlocking] BipulJamatia19:

The modified firmware is rolling back to stock firmware after few days R6.16 . Is there a way to stop this update? @abhimortal6

could you change the firmware to v99.99 or something
[Upgrading, Modifying and Unlocking] sdomermpc:
For devices not detecting in fastboot, (or detecting in adb but not fastboot)

1. Open device manager

2. Select usb device, open properties,then driver tab

3. Click update driver, "browse my computer for drivers",

Then"let me pick from list"

4. Select "google" in manufacturer, and "Android bootloader interface" in model

5. Click yes

Now Check in cmd , with command "fastboot devices" hopefully the device will detect
[Upgrading, Modifying and Unlocking] chaitanyakorde:
I managed to fix the issue, but thanks for the tips anyway...

You need to flash your recovery partition as well. Check FAQs of the article.

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 b

fastboot erase recoveryfs

fastboot flash recoveryfs "D:\system.img" y

Hello,

abhimortal6​

I can't thank you enough for the hard work and effort you put into this project.​

I myself searched for 2 years😥 for a solution to this problem but finally I'm glad that I came across this forum.​

​

All the instructions are simple to follow. (And let me tell you I'm a doctor and have zero computer knowledge and i was still able to follow every step effortlessly)​

​

I got my jiofi - JMR 540 working with an airtel postpaid sim with automatic API settings which amazed me.​

I will be forever greatfull to you.

You have my respect.

WE NEED MORE PEOPLE LIKE YOU IN THIS WORLD. :)

Hi @abhimortal6

Recently i got a JMR1140 from a friend, i wanted to change few things on it so i decided to edit the firmware on it.

It doesn't have a fastboot mode, just Qualcomm's EDL mode. I opened it just to find that it has JTAG pins instead of UART.

Then i decided to edit the UBI image.

If i create a UBI image from the unmodified rootfs then the device boots just fine. But if i repack the UBIFS image with or without any modifications the device refuses to boot. Any idea?

I edit the image without unpacking (hex edit) i was able to edit that. But UBIFS repack isn't working for me. Don't know what I'm going wrong. Size and all are all correct.

It started from last week, but prior to that I was using vi and Airtel, didn't face this problem. Now on jio sim, it switches off wifi exactly at 12pm, 6pm and 12am.

maybe jio is pushing this setting over the internet.

right now without the admin help, the only way is to turn off the device during these specific Times. I mean connecting to pc with usb is pain and so is resetting every time when wifi goes off
