And for the engineer key thing. It's impossible to do a bruteforce attack as it would take more than a billion requests to the server considering the number of password character is 12 (as from the script code) and the character set length is 15.

Our only option is to gain access to system via adb(as it is an Android OS, it might be possible by shorting some IC pins to enter recovery mode) , as fastboot is of no luck, with limited options. Or ultimately, someone from Jio generous enough to provide the firmware file.

Bro the firmware provided by @upi-turin has adb access as he himself extracted the firmware using adb. But I am unable to flash the zip through the fastboot mode. If we can somehow make a bin file and upgrade through the web UI maybe we get adb access.
I don't use special software for those links. They are just hit and trial results and some through burpsuite spider.
Also the engineer key page uses anti-csrf tokens so it becomes more difficult to attack. The password length is not necessarily 12 as it is first encoded using md5 and a substring is chosen. This substring is then further encoded using the character set of 15 and posted in HTML request along with anti-csrf token.
Do you know how to decompile or open a firmware bin file?

If you carefully read the JS code, the ultimate length of encrypted password is 12 and it comes only from the characters in 15 length character set. It's still a probability game, who knows if JioFi manufacturers have made the JS look like that, to waste the reverse engineer's time.

For the system folder part from the gdrive, it is still debatable. It's not sure enough for me, that guy has accessed the device through ADB and providing the original files, or just some other files from unlocked firmwares of previous JioFi.

The firmware bin file is mostly just a zip file, if security aware, a magic hashed zip file. If you're using Linux, try binwalker it will tell you exactly the file type, even if it's magic hashed.

I think only certified authority can access to engineer mode as they can repair it.
They have key to do something

I went to Jio Centre and thanks to the warranty they replaced the whole motherboard of the device free of cost. It now uses firmware version PEG_M2_B20
UPDATE : @sydikm shared a firmware file with me which is exactly meant for our JIOFI 2. I will share its in OP. Its version is PEG_M2_B04 All credits to @sydikm
