hp-15c LE firmware update HOWTO? - Eric Zoob - 10-12-2011

I purchased two of the new 15C LE calculators with firmware 2011-04-15, and have been following the posts here. If a firmware update is made available, how will it be made available? i.e., can I send my calculators to be re-flashed (to HP, or to someone who has the cables and has done this before with other HP calculators), or will I be expected to do it myself somehow? How has this worked in the past?

These are all good questions that only HP can answer.

There has been no systematic way past ARM-based HP calculators have been upgraded after purchase. Some people do it themselves by getting a cable (from HP and now via Gene) and asking HP for the latest firmware, it's not posted anywhere. The HP website/manuals don't even acknowledge that these machines can be upgraded.

Texas Instruments makes operating system and software updates for its handhelds a big feature. For example, see here:

there's a SDK for the 20b available from HP, containing a firmware file. I found it somewhere on HPs website and used it to update my 20b. So, some acknowledgement has been made.

I sent you an e-mail a couple of days ago but didn't hear back yet, I'd like to order one of the cables form you.
