Attempting to access shell Airtel F670L using UART

[shahidcodes]

then maybe check the adapter? I got the output on that boud rate

Is there a connection that I'm unaware of?
Also what software did you use to communicate with ttl device?

 

[shahidcodes]

I used minicom, can you show your pins?

 

[thisiscorgi]

I will share photo in 30 minutes

 

[thisiscorgi]

The order of pins on the board is TX RX GND VCC right?

 

[saurabhshri]

Most definitely a dumb question -- what could be achieved by getting a shell on ISP ONT?

 

[JB701]

you can do whatever you want, its the linux shell so you will be able to run linux scripts, see all the files etc

from bottom up: vcc gnd rx tx ?

 

[thisiscorgi]

So I was able to get into the boot process but it's not taking input.

Can you guys help why?

 

[thisiscorgi]

update: the newer f670l has different order of pins, its vcc, tx, rx and gnd from bottom up from my last pic.
i see boot process, can stop autoboot and i am limited to some uboot commands but if boot is not interrupted, it proceeds to boot completely.

upon hitting enter key, it asks for login and password but unfortunatley whatever combination i tried from the internet resulted in failure.

so if anyone knows a way to retrieve the pass or has gained access to it via uart, please share your knowledge.
