Telepresence codec C40 recovery

[Sergey Popov]

Hello

I had error on web interface of C40. It was maintenance page with such recovery options as upgrade factory reset and something else. 

Upgrade didn't help - on web interface still was only the maintenance page.

And after factory reset I can’t ping it. And I have error message on monitor (screenshot attached) which tells that factory reset can solve the issue.

Now I can do factory reset C40 only using the serial interface.

I find commands for this in the C40 guide (xCommand SystemUnit FactoryReset Confirm: Yes). But I have other commands in CLI:

 - User Commands -

help                factoryreset        log                 pkgverify
reboot              remotesupportuser   rootsettings        selectsw
startweb            version

I tried to use command factoryreset. CLI answers “OK” but nothing happens.

How can I do factory reset or some recovery?

Maybe it’s possible to reinstall soft for this codec?

Thank you.

Hi,

You may need to upload the image through TFTP this is going to install a totally new image from scratch.

Hello Dmitry. Thank you for your reply and for this guide.

Now I try to assign IP to the codec

URL to files pkgextract.elf & u-boot.ini  from this document not works.

Does anybody have these files?

I had started upgrade without these files and I have big trouble now - Any image can't start and I don't have any access to codec.

Thank you
