I tried to reset one of my modems using the 20 second pin reset. I was trying to put in a good XML config, it was not an issue of a bad firmware flash image, and I was hoping to get the configuration reset so I could load up a known good backup if the XML. A lot of failures were endured, I was using an iPad, which is all I have these days, and I think I hit a lot of bad bugs in Safari/iOS which are triggered when you are using a setup that has no dhcp server on the LAN and you have static rfc 1918 made-up addresses temporarily.
In the end I managed to ping the modem’s admin i/f at 192.168.1.1 and in a web browser I got the emergency recovery http-server in boot loader thingy. In Safari / iOS on my iPad I could not see any web page at all, so I tried a different iPad web browser, iCab. iCab gave me a half of a web page, the bottom half of the page was missing and there were 0ther things wrong with the display. I just don't have another machine at hand, tried three iPads. I have gone through the procedure successfully before, that is the weird thing, but the iOS version is now different, although I used an older iPad to rule that out. The firmware version is different, is our own johnson's latest jumbo v16-based one, dated late June. I did a recovery using Safari on an iPad with this very same emergency boot rescue http thingy.
Anyway, that modem is now effectively stuffed as I cannot out a good config into it.
The normal http server was no longer working after I fiddled around with the device using the CLI in telnet, trying to get DNS working properly and a few other things.
I could try the 30-30-30 reset, but I am completely exhausted now and cannot think straight.
Does anyone have any suggestions concerning de-bricking?
It does respond to pings and has some life in it as shown by the funny web page appearing, when you put it into the right state at any rate.
Otherwise I might appeal to a very generous volunteer to de-brick it for me?
