C7837WIP - Error Firmware Upgrade

Hello. I have attempted to update the firmware using the firmware upgrade tool for windows. It started but failed before completing. I got an error but I didn't capture it. I have reset the camera using the reset button for 10 seconds as instructed in the manual, but it doesn't start anymore. Lights on the ethernet port are lit, and it gets an ip address, but I can't connect to it

C7837WIP is the cam model.

Please help me.

also tried to use Update tool or LAN Cam finder, but camera is not recognized anymore.

I’m able to use telnet on port 23, but I don’t know username and password.

I think the upgrade tried to install a firmware that is not compatible with C7837WIP. I think it was version 74.

How can I downgrade back the firmware?

Thanks

I also tried camera reset many times, but it’s not working

Any news??

Hellloooooo?????

Sir/madam,
I suggust update the Eye4 App version,and then try it again, any question, contact me again.   

The default login account:  username:admin, password:888888.
Pls reset it and then input the default account.

Hello, I already did the reset of the ipcam without success. The cam now, when it restarts, doesn't neither turn off lights nor move and do the tilt and rotate initial panoramica. But it's connected to the Wifi and gets an IP. I think this is because the firmware upgrade done with your tool failed and there's something wrong.

I'm using PC version of Eye4 version 1.3.0.90 and there's no new version.

If I try to do the telnet on port 23 it responds, but username admin and password 888888 is not working. What can I do?

Hello, can you please let me know???????????

I'm completely pissed off by this lack of support. Either you will provide me a real and working solution or I will report that on all the social networks and on my electronic review website that Vstarcam is not providing an adeguate post sales support and your products fails doing a standard upgrade.

Waiting for an answer by the end of this week...

Hello? Someone there ? No one can help me???
