Hello . Is there no solution for the updated versions? Is there any hope? There is no complete and correct tutorial for activating the Diag port? So that we can unlock the modem via qpts and backup xqcn and erase efs2? I checked the modem bootloader, it is not locked and you can easily inject the patched loader of 9207 Qualcomm processors through the 9008 port. The problem is elsewhere, if anyone can or knows how to help so that we can get the modem from the diagnostic port and adb ports. Nothing is clearly said on this Twitter account! What is the module used in videos and photos and where can it be obtained? There is no training or guidance? In India, with such a large population and so much density, does it mean that one person could not unlock new versions or find a way and access to Diag and adb ports? If we have a diagnostic port and can get xqcn from the modem and also have adb access, and due to the presence of port 9008 in the modem by connecting the boot point and hitting the patched loader, we can even fully dump the modem, ie from a backup unlock version Prepare through port 9008 and patched loader and then burn on the locked version and thus all locked modems can be unlocked

[Upgrading, Modifying and Unlocking] damaruk:
Thankyou Boss, You saved my purchase. I bought this device two years back without knowing jio signal poor in my home, the device was useless for me.

I successfully flashed. Now it is working with Airtel.

Any one tell me, Do I need to flash recoveryfs also.
[Upgrading, Modifying and Unlocking] damaruk:
Thanks a lot
[Upgrading, Modifying and Unlocking] Shoppygadgets:
ThankQ So Much finally Unlocked after 1 year
[Upgrading, Modifying and Unlocking] Susamay:
It was working properly but two days ago this happened. Tried reflashing (both system and recoveryfs) but didn't help. Booting takes much time and there's no network when sim inserted (for obvious reason).

Could it be hardware problem (I don't know nothing about nothing)? Or do I need to try the other ways (like writing imei and etc) ?

abhimortal6 if you still follow this thread, it would be helpful if you reply.
[Upgrading, Modifying and Unlocking] abhimortal6:

Hi,

Today I have flash the patched firmware on my JIOFI 3 which was running the version "JMR 540 - FXN_JMR540_R6.10"

- I have Flash both - system and recoveryfs

I am able to use other sim card in this (Thanks alot for this)

My major concern is that:

Will my device gets auto-updated (which will lock the bootloader)?

Should I continue using it or stop, will it get autoupdate even on latest unlocked patched firmware?

[Upgrading, Modifying and Unlocking] PROsenGt:
My JioFi got updated on very first day when jio pushed new firmware and locked bootloader. After checking for several weeks for any chance of revival I reached out to @abhimortal6 and he was welcoming and kind. This was his reply then -

"Hi, it can be unlocked but there is no easy way to do it, it basically requires shorting JioFi into unsecure EDL and re-flashing old bootloader"

I am hopeful we'll see another unlock 🤞
[Upgrading, Modifying and Unlocking] attari13:
need apn for airtel thanku
[Upgrading, Modifying and Unlocking] bhupatib:
works great!

few issues i faced and managed to fix 👇

1. "fastboot devices" not showing anything

what fixed it: make sure you have installed the adb driver (which contains the generic google android usb driver) linked in the first post. then with the jiofi connected, go to device manager and find something similar to "android device" "unknown usb" etc with a yellow warning icon. right click and click update driver, manually select the google usb driver and jiofi will now show up in command line.

2. even with successful flashing the dashboard didn't show the "this is a hacked firmware..." message at the top meaning that somehow the flash didn't work"

what fixed it: as mentioned in the FAQ, you have do both "fastboot flash system" and "fastboot flash recoveryfs" with the same hacked system.img

rest went smoothly :)

[Upgrading, Modifying and Unlocking] jithinvp4:
@abhimortal6

Can you share where is the testpoint located on JMR540 board to short and boot EDL mode and which tool can be use to flash old bootloader.
[Upgrading, Modifying and Unlocking] subhash_india:
Uart pins Tp701 tp702 to703 find gnd pin using digital volt meter and remaining pins are rx and TX , connect using TTL to usb , don't connect VCC of TTL converter, give power from adaptor to jiofi , use putty in serial. Get adb shell. Backup jiofi , flash later.
[Upgrading, Modifying and Unlocking] jithinvp4:
Thanks for your response

But since bootloader is locked ,only way to flash old bootloader is via EDL ,but not sure what is the exact process.
[Upgrading, Modifying and Unlocking] subhash_india:
Find edl points, short 2 edl points and connect usb cable to get shell. Or find clk pin and short clk to gnd pin simultaneously by contacting usb cable , boot short device.
[Upgrading, Modifying and Unlocking] subhash_india:
One more trick is to disable TR069 in jiofi devices to stop firmware update! Permanent solution.
[Upgrading, Modifying and Unlocking] jithinvp4:
i am attaching JMR540 board pic , how we can identify EDL points?
[Upgrading, Modifying and Unlocking] subhash_india:

[Upgrading, Modifying and Unlocking] YOURKIN:
TP701 , TP702 ,TP703 Pin for RX , TX and GND . please check Ground (GND) pin before connect .

*** Near Barcode
[Upgrading, Modifying and Unlocking] jithinvp4:

are your able to locate EDL pin ?
[Upgrading, Modifying and Unlocking] YOURKIN:
yes . also backup main firmware .
[Upgrading, Modifying and Unlocking] jithinvp4:
I got the exact procedure to backup current firmware and enable ADB.

but still not clear how i can flash old bootloader to unlock current bootloader which is locked by vendor.
[Upgrading, Modifying and Unlocking] subhash_india:
Did you backup jiofi M2 or m2s firmware? , I'm not able to locate uart pins on M2 , it seems edl points are there along with uart pins on M2 , I shared pics of M2 with you but you have doubt in finding TX pin. So did you found any updates about M2 so far?
[Upgrading, Modifying and Unlocking] YOURKIN:
no but i have ANDROMAX M2Y backup without system.bin ( Similar JioFi M2S and * M2 ) Helped by @santoimam
[Upgrading, Modifying and Unlocking] subhash_india:
Ok, good.

I'm trying to find out engineer page login password, if we get that it's very easy to enable adb. They disabled adbd demon, adb_key is used as password in plain text. Adbkey is encrypted as md5 and base64 inside rom. Some get methods can be used to retrieve adkkey and decrypt it to plain text. It's only possible If we enable adb.
[Upgrading, Modifying and Unlocking] yadhuuk:
without TTL connection, can we enable EDL mode ?
[Upgrading, Modifying and Unlocking] YOURKIN:
yes if every thing unlock then we can use usb for EDL mode.

Managed to get UART console ,but i am not getting shell

@abhimortal6 are they disabled shell access on new firmware?

The modem must be unlocked in principle, that is, the plmn lock must be removed and acs or tr069 must be closed. In this case, the operator of the modem can no longer send updates and lock the modem. In order to unlock it with an airtel SIM card, refer to bands. which the modem supports and the bands on which your operator provides internet and network

if you really want to try , get root shell using TTL to UART converter -> start adb service -> boot to EDL from adb -> use qxdm to enable band
