Hello,
I updated my ROM to v215 to get rid of the ROM compiled with HPGCC3.
I used the conn4x_b2361 for the update and everything looked ok ( the only thing i didn't do in the update process was to disconnect the USB)
I pressed enter at the end and it asked me if i wanted to recover memory, i said no. The calculator looked similar as it had been turned off, but it was not responding to any keys and making a beep sound.
When i remove one battery or reset the calculator i get the "try to recover memory" window. I tried no and yes and the same thing happens.
Any idea on how could i recover my calculator?
Thanks in advance.
calculator should boot without using libs.
delete libs of port2 (push LEFT-KEY and "FILES" (APPS-KEY)).

PUSH AND HOLD the DELETE-KEY (the key right of SMYB).
USE A PAPER CLIP to PUSH the reset-button (next to the serial number on the back side of the calculator).
RELEASE FOR AN INSTANT the DELETE-KEY
calculator should boot without using libs.
delete libs of port2 (push LEFT-KEY and "FILES" (APPS-KEY)).
or
PUSH ON-KEY AND C-KEY or PUSH ON-KEY AND A-KEY AND F-KEY
PUSH AND HOLD the DELETE-KEY (the key right of SMYB).
calculator should boot without using libs.
delete libs of port2 (push LEFT-KEY and "FILES" (APPS-KEY)).

Do you have a suitable SD card: 2GB (might be 4GB) or smaller, formatteddid it work?Thanks a lot for your help, but all i get is "try to recover memory?"

as FAT but not FAT32? If so then there is a way to upgrade the firmware
via the SD card and no need for USB.
Instructions are here: <https://www.hpcalc.org/hp49/pc/rom/>
Where the instructions say to copy the "update.scp" and "bin" files onto
the SD card, you can get those file from the Zip file here: <https://www.hpcalc.org/details/7097>
I don't think it would do any harm to unzip all the files into the SD
card, as long as they are all at the top level and not in a sub-directory.
That zip also contains installation instructions which are slightly different. I would start with the ones on the link I posted first.

Change the main batteries first. If the low battery indicator stays on
then it means that the coin cell battery is also low.
