Flu Card serving blank (black) page


I've been a long time lurker in these forums, having found a lot of information about my cameras of choice. But today I'm stumped.

I own a Pentax K3 with a Flu Card. Starting a few days ago it now only serves a blank, black page in the browser. No controls, no preview, nothing. After first attempts with my phone's browser I decided to give a desktop browser a chance to see whether there were any issues with the page, or whether some recent OS update on the phone had broken it. But no, same problem in Safari. And indeed I'd get an error message in it's dev console:

SyntaxError: Invalid character '\u65533'
(anonyme Funktion)
Or in Firefox (which I know not to be supported, but features some better debugging tools):

SyntaxError: illegal character
...s = 21; pagePlayb������������
Ok, there definitely is an issue with the code. I then saved the downloaded html file and opened it up in a text editor. And searching for above "pagePlayb" does indeed bring up some odd looking code:

 pageStatus = 21;    pagePlayb������������������������������������������������������������������������...
(followed by many more of these � characters, #65533)

It seems as if somehow my Flu card has got corrupted and is serving broken code. Has anybody seen this before?

I tried to fix the filesystem (which did indeed report issues), but would assume the code was stored in some read-only place, protected from being overridden. I did reset the communication settings, too. To no avail.

The card's firmware version is, Content Version

Any help would greatly be appreciated.

Can you try to re-install the latest firmware by following the procedure at the support page?

You should wait for enough time to complete the upgrade process before you remove the card from PC (step 6 of the updating procedure).

Just recently bough K3 with flu card, which gave me several headaches before ( with the help of some forum members) could figure out what was wrong and how to fix it.

Check this thread:

One issue not mentioned in that thread and is probably related to your problem, is your smartphone's (tablet's) browser's cache, thar it may be trying to load the pentax flucard from cached memory intead of actual new connection.

Try clearing browser cache by deleting browsing history and then establishing new connection with camera, starting with camera off, then turn on, wait 30 seconds then check wifi connections. Pick flucard, open browser and hit refresh button on browser.

This should establish a fresh new connection without showing any previous error message that may be cached.

Let us know your findings.

Thanks K-3-lover! I re-flashed the latest firmware, and this indeed brought the card back to life. I should have tried this earlier...
