RE: newRPL: Firmware for testing available for download
Thank you very much for the detailed explanation.
New RPL firmware installation went smoothly. I got the expected message at the end : WAIT, RESET, ENTER. However, after removing the battery as explained below, I was left with a blank screen and a dead HP50G. So I tried again, this time pressing "ENTER" instead of removing the battery, same result. In fact I tried a lot of things: - Removing all batteries, including the button cell - Waiting a lot of time after removing the batteries before reinstalling them - Pressing the reset button instead of removing a battery - RE-installing the 2.15 HP firmware before trying the newRPL installation again - Changing the SD card - Tried every keys, played with the contrast - All of the above on my HP-49G+ instead of HP-50G In all situations on both calculators I get a blank screen. Every time I re-install the HP firmware the calculators work as before. Don't know what else to try. François (09-11-2015 05:43 PM)Han Wrote: As already mentioned in previous posts: |
