This article applies to Dericam H502W, Cybernova WIP604MW and compatible models.
Although they're hard to brick, some operations may sometimes produce similar symptoms.

It's now an old habit, I only start to feel safe with any Android device once I managed to install a Recovery partition such as ClockWorkMod.  This is how to do it on the Onda tablet Vi40 Elite...

This post is just based on the comment #113 left on the popular page "Bring your FI8908W paperweight back to life" so all the credit goes to Eduardo Yoshida.

It describes an alternate method to recover from "Error Web UI '(app_ver = '0 .0.0.0') following a firmware update. In this situation, the Web UI is unavailable for re-flashing and some version of IP Camera Tool will not work well.

I published my post, Bring your paperweight back to life, in December 2009 with recovery files received from Foscam at that time.

This worked fine for all users of FI8908W (and FI8904W) until some hardware revision that occurred in Foscam's produced during 2010. The initial files didn't work any more for these newer cameras.

I have updated my post with files (+ mirror) that Foscam confirmed to be compatible with all the generations of FI8908W and FI8904W.

If you're part of the numerous people who bricked their ip camera at any stage, maybe you kept it (as a door stopper, a paperweight or a dummy camera). In that case, there is one last thing you can try to make your camera functional again. It requires a small investment of less than €15 so I think it's really worth trying.

I obtained some information recently, thanks to Foscam tech support for most part, on a serial upgrade method that would fix cameras for which the firmware upgrade went bad.
