Extended a 15-100, now its stuck

[JaguarIV]

Hi all. I recently took the plunge into JP1'ing after purchasing a Radioshack 15-100. I followed Tommy Tyler's instructions for adding a cable to the remote. I also followed Tommy's instructions for creating serial interface. I got everything working and have been uploading and downloading to the remote with no problems. I got ambitious and decided to load the 15-100 extender. I loaded and activated it fine, but missed the step that I needed map the 'Deactivate' function to a key. I did what I think was the right mapping and re-uploaded. After pressing the deactivate key, the LED blinked 5 times as it was supposed to, but then went into some awful state where it just sits and blinks a series of four flashes, then pauses for about a second, then four more blinks. Every element in the LCD is also on.

I then tried to upload the default configuration, but that didn't work either. I tried every function available in IR 8, including 'Clean Upper Memory', 'Initialize to $FF', and 'Initialize to $00'. Nothing was successful at clearing the blinking light. IR never complained about not being able to complete an upload, but I wanted to confirm that my uploads were doing something. So I opened a second IR window to download the remote after trying an upload. It was here that I noticed that the remote contents don't appear to be changing when I upload. So it appears that the remote is stuck in such a way that I can't even upload to it, even though IR doesn't complain about not being able to write. I have tried to do a 981 reset, but that hasn't worked. The manual gives a reset procedure, but it requires going through the menus, which I can't access either.

I also tried fiddling with the batteries. If I take two of the four out, then I am able to get the LCD screen to show a Low Battery message, and if I press and hold Setup, it will prompt to enter a language, but then does nothing more (although the LED stops blinking for all of this).

I am at a complete loss as to what to try next. Any suggestions are appreciated.

The raw dump of the remote in its current state:
dload.php?action=file&file_id=7770

The original IR file from the remote:
dload.php?action=file&file_id=7771

first try a fresh set of batteries. The JP1.3 remotes go into a low-battery state and blink 4x on every keypress and then send the key. If that doesn't work, send me a PM and then we can discuss this off line, I'll send you my email.

After a series of off-line emails the remote is back in action. Somehow he got a partially activated extender. I've been scratching my head trying to figure out how this happened, especially since the activation method is the same on all of the JP1.3 extenders and if it's corrupting things I really need to understand.

But the good news is that the remote was not completely out of wack and it's back on line.
