I realized using the SD cards were very simple. Yes I installed firmware version 2.15 on that HP-50G. IPhone SIM eject tool is great to push the HP50 reset button. If no dialog is presented "ON A F" key combination will send you to it.Īlso remember to use standard SD card (not SDHC), formatted in FAT16. Try to recover Memory: "NO" after the upgrade is the perfect end for old data (and any weird behavior). I use the files inside "2M FIX.zip", as they will wipe out everything, and truly revert Flash to factory conditions. Even if it came with in latest software version.Īlso re-flashed a lot of times going back and forth between standard and NewRPL images.

it took a Catholic priest to help perform exorcism of evil software that took over a machine!!!
Now the 50G wakes up like a normal machine!! I was able to get to the files of the Survey software and delete all the files. You sir are a WINNER!!!! Your instructions were spot on. I had the calculator packed ready to return it. However, if you saw any libraries in the menu area, then you were not holding down the backspace key throughout the warmstart. If you see no libraries listed, it was a success, so press left-shift APPS (FILES) and begin deleting what's in HOME and ports 0, 1, and 2. Press right-shift 2 (LIB) and look at the menu area. Continue holding it down until the warmstart finishes. Next, in very rapid succession, release the ON key and then immediately press and hold down the backspace key. Method: With the calculator turned on, press and hold down the ON key, then tap and release the C (F3) key. This is a great way to keep a library in Port 1 or Port 2 from taking over your 50g, after which you can delete it using the FILER. If you hold down the backspace key DURING a warmstart, it will prevent all the libraries from attaching themselves. It's a takeover library of some kind in Port 1 or Port 2.
