How to reset Onkyo Amplifier using Shell Commands?

Hey guys,

TL;DR – I got an Onkyo TX-NR646, front panel and remote is unresponsive, but amp works through Wi-Fi. Skip the questions at the end if u dont wanna read the whole story

I am an Onkyo Amp user ( yeah, ik sucks to be me). Bit of a backstory, I owned 2, one of them broke spend 75% of original cost to ship a replacement board from over 6000km away, coz I live in Sri Lanka.

The one I have the problem is with the Onkyo TX-NR646, somewhere around doing a software update it crashed… and you guessed I had to replace the WHOLE DAMN BOARD, coz onkyo thats why.

Past a year or so, everything is fine with the TX till yesterday, the remote and the front panel stopped working, at all. I have to say all the AMP features work 100%, I have connected it to Wi-Fi so I can use the Wi-Fi remote and it works perfectly. But the buttons on the front and the remote do nothing at all. I figured it was a loose ribbon so I opened it up and re connected stuff and still same issue. Somehow the front panel started working, for like 30 seconds and stopped. I resetted it in that time frame and regretted cause now I have no Wi-Fi control either. Somehow I managed to mess around and quickly connected to Wi-Fi before it became unresponsive.

Before anyone mentions, ik a lot about onkyo amps and their problems so I did the usual, power off, disconnect everything blah blah blah. Right not I am not sure if its a software or a hardware problem.

So I booted up my PC and decided to access the Linux Shell of the Amp (telnet). Worked fine, I found a github repo on some EISCRP commands, so it was easy to get by, but now I wanna try two things and that’s what I want your help on.

Question 01 – How to do a fully Software reset of the amp, using the command-line shell?

Question 02 – Can I get a backup (ftp doesn’t work btw) of the entire software to my computer, in case something happens?

Question 03 – Should I do a firmware update (it is already updated to latest) and hope that it starts working again?

Thanks
