8924 Bricked on reset :-(
« on: February 01, 2021, 10:45:29 AM »

Hi All

As you might see from my other posts, I've been messing around with bridging setups to try and get VOIP working in bridge mode.  Got into a messed up state in my 8924 (spare one thankfully - that's why we have spares) so did a reset - and.... it's bricked.

When I boot it, I get LAN lights for the active cable and the flashing power light, but once that stops working, the Wifi lights flash orange one and dissapear, and I can't connect to the router at all.  Tried static IP addresses etc., but just no go.

Could someone point me at a recovery guide - I've tried just holding the reset button until it resets of course.  Any recovery mode, or TFTP type update.  If not, is there a serial reset guide somewhere?

If the long reset isn't working then serial port may be the only option.
There's a youtube video on the vmg3925 which I used to help me unlock one of those - - hopefully the 8924 is much the same.
I also wrote a very quick tutorial when I couldn't get the config file upload to work -,25402.msg426262
The USB-TTL device I used was one of these - (mine came from a different seller, but the same device).

Thanks tubaman.

Yes, I've tried holding the reset down while powered on, whilst powering on, etc..  It'll happily boot up, but it's clearly got into a mess.  WiFi isn't loading at all, and it doesn't seem to be accessible in any way I can find at the moment.

So, it's serial reset time I think - not happy while I haven't got a spare.....
