So, today I decided to mess around with getting access to my Airtel F670L router's shell.
I was earlier trying to access the SPI flash chip of my Excitel router earlier but that wasn't able to, soldering small chips is difficult for a newb like me. So, I decided to try something easier before doing that, soldering wires on the UART pins of Airtel router to access the shell using TTL Cable.
I know its a mess, i didn't clean up the flux and the yellow wire specially looks bad (though that pin is +5V and isn't needed). Thankfully I didn't short anything with solder.
After connecting orange color to TXD, green to RXD and red to GRND. I was able to (kinda) access the shell at baud rate of 115200. Sadly, I wasn't able to transmit anything to the shell. Will mess with this again when I have time and update this thread. Maybe I bridged some pins while soldering.
Here is the output file if anyone's interested (not much on there just the boot sequence stuff).
