Thanks for your time for putting this together and sharing to others.

Is there any way to add start up script you're aware of. I tried /etc/init.d script to run commands by adding script and invoking another script but it doesn't seem to work.
The router has crontab but missing config file creating anything is running only under /tmp root path. I wonder is this kind of virtual env for telnet? nothing is persistent....,
Can we do this script in enc file execute code (I'm referring os execute code in config)?

This will initialise successfully but web UI isn't accessible.

after using openssl to decrypt using the provided key file the file generated cosists of some chinese symbol and in the console its throwing message of bad decrypt. I am having router of firmware SRCMTF1_JCOW414_R2.41

Is entware working. Can you share the configuration for setting it up ?

OpenSSL gives the following error

*** WARNING : deprecated key derivation used.

I tried enabling FTP in my JioFiber following your steps,
While restoring it gives me checksum error even though i changed config.checksum = "0" in my decrypted file and continued.

My router description :
Model : JCO4032
Firmware : SRCMTF1_JCO4032_R2.35

hi.
i have been a jio fiber user for quite some time now and i feel pained in logging into the router to check stuff.

my idea. is there a way to get api access or something, like from a get/post which we can use existing solutions like homeassistant and connect the same there.
for example, i would like to see how many connected users i have on the router, the homeassistant would send a get request and get data from there or something like that.
just..... pushing ideas out

I got the key: RRIOTJI00000524XXXXXXXXXXXXXXXXXXXXXXXXXXXX (<serial_number><32 char string>)
then i used this command to decrypt the back up file:
openssl aes-128-cbc -d -pass file:key.txt -in RRIOTJI00000524_JCOW411.enc -out RRIOTJI00000524_JCOW411.txt
openssl aes-128-cbc -d -md md5 -pass file:key.txt -in RRIOTJI00000524_JCOW411.enc -out RRIOTJI00000524_JCOW411.txt
had the same error

Using -iter or -pbkdf2 would be better.

I have done the telnet part. And got access to it.

I wanna use this as my own modem as my isp modem sucks
My isp requires a vlan id of 528 and a pppoe username and password

I have tried configuring .enc and flashing it with no success.

Any ways i can do this.

hey so i am using my orange pi board as a pihole and DOH server on my JIO Fiber connection , i also tried to make a vpn using PiVPN it worked and the vpn was made using OpenVPN, but it uses the routers public ip address which is supposed to be dynamic but hasnt changed ever so that isnt the issue but the issue seems to be port forwarding as i cant reach my jf router via th e public address, is therr any way to actually enable port forwarding on the router if i enable the root user, just wanted to know before i go down that path, would appreciate any help and ideas otherwise too.

Hi, I'm trying to update my jiofiber router firmware to the latest version(R2.9) but I'm getting an error saying firmware file is invalid or corrupted. Tried multiple update files but getting the same error. Is this a know issue or am I missing something? Please look into this issue. Thanks.

Here's my router information :
Model - Skyworth JCOW407
Current firmware version - SKYWTF1_JCOW407_R2.52.2

I have a jio fibre router, as it does not support ipv4, i want to do it with ipv6. how to do it, can you help me with that.

telnet: Unable to connect to remote host: Connection refused

I get this issue when I try to connect to the router
using this command = "telnet 192.168.29.1 23"

What should I do?

I have uploaded the file with the neccesary changes to my router (JCOW404)

Hi,

The firmware URL changed. currently with your method I am getting upto 2.49, but last night router upgraded to 2.52, and I didn't get the url for that firmware.

The old keys are not working

I recently installed jiofiber wired network for my projects. I got one WordPress project, which is to update the theme. I updated the theme after that I checked the updated website. I was unable to see the updated version of the website by using jiofiber net when I used another network I can see the updated theme. For this reason, I lost my project. So Software employees and software companies do not use jiofiber network.

Expected Behavior: To Successfully be able to import the .enc file.

Actual Behavior:

Steps to Reproduce:

1. Decrypt the file using the keyguesser.py script
2. Add the starting of telnet daemon and other iptable configurations to the config file and then replacing the old md5 hash with the new correct one.
3. Re-Encrypt the file using the Hex version of the key.

Verification: keyguesser was used again to verify if the key is able to decrypt the modified encrypted configuration. (It returned the same key and correct decrypted data)

trying to decrypt the configuration file for JCO110 with firmware ARCTF1_JCO110_R1.148 leads to a bad decrypt.
Can you explain how did you extracted the encryption keys in the first place?
How did you reverse engineer the firmware? Thanks you are doing awesome work.

I ran the script but I got Failed output for all trying keys. Please help to get the key file from my Jio router.

Firmware: SRCMTF1_JCOW414_R2.41
Model No: JCOW414

Thank you in advance and I really appreciate your help.

Hi, I rooted my router today but I noticed that everytime it reboots,
telnet access is gone and I have to reupload the hacked config file...

my scripts both in /flash and /flash2 also do not run despite being both chmod +x and executable throught telnet

#!/bin/sh

What can i DO?

command used after generating key from keyguesser.py:

openssl aes-128-cbc -d -pass file:key-success.txt -in RAROTKH00053021_JCOW411.enc -out RAROTKH00053021_JCOW411.txt

Problem: the decrypted txt file is still just a garbled text.

Internet suggested to use LibreSSL, but I couldn't get the windows version to work.
I don't have a mac.

• I was able to download backup key using the method mentioned here: https://github.com/JFC-Group/JF-Customisation/blob/master/Instructions/Get-Any-File-From-JF-ONT-Home-Gateway.md

• However, using the command:
  $ openssl aes-128-cbc -d -pass file:<key.txt> -in <input.enc> -out <output.txt>

But it gives this error:

Pls. help..

Is there a way to run shell scripts during the router boot up?

I used the steps here but it seems that they might have added a checksum verification

So the above is the sha256 sum of the original .enc downloaded from the maintenance page

Here is the checksum of the new file created with the modifications on the instructions page as you can see they are different
I have verified that the original file works following which i tried to use the modified file and i get this error

Here are my device details

Firmware Version SRCMTF1_JCO4032_R2.52.1

Hardware Version 0003

Model Name JCO4032

Please do help me out

This is a bit farfetched but is it possible to get bash running on JioFiber?
I tried using a bash build for MIPS but it doesn't run.
I'm thinking of maybe running a small bash script on the router (uses less than 10 MB of ram and doesn't require much CPU either so it should be possible)

Thank you for your hard work.

I am trying to upload the modified .enc file to gain root access. However, I am getting an error page. Please see the screenshot. I also tried to change the password to something else with capital letters, special character and numbers. Still, same error.

Hey guys!

How do I get the decryption keys for my specific model which is ARCNTF1_JCOW411_R2.21 or JCOW411 ? I'm trying to dump the plain data (or get telnet access) inorder to get the details to connect the fiber directly to another box I have (using an SFP module).

I am running the firmware that was uploaded in your git repository and I'm using the steps correctly, the enc file generates does contain the necessary changes in the first line. But when I upload the following enc file, the router restarts (photo attached below) and reverts back to the original enc file.
