Is there any way to prevent the Prime from formatting when something crashes it?
I have been experiencing crashes almost once a week and thought there was something wrong with my G2. Even though it is still new, the problem could be bad memory blocks or something else. It's not the crashing that's frustrating, it's the fact that every time there's a crash, everything gets wiped and I have to start from scratch all over again. Luckily, backing up and restoring works well and doesn't take long (since I haven't installed a lot of things yet).

I was experimenting with the solver app by Han when the calculator crashed. Luckily, this time, I knew exactly what I was doing and tried it again; the calculator crashed. This tentatively proves that there's nothing wrong with the calculator from a hardware perspective, which makes me happy. However, this makes me extremely wary about using the calculator as the calculator could crash in an exam and everything gets wiped. Why does this happen? I have no issue with the calculator crashing. I just don't want everything to get wiped.

In case someone wants to try it, install the latest solver app by Han, choose motion, terminal velocity, and try to solve without changing anything.

I personally experience a lot of crashes with forum software using my G2 as well. Especially the BodePlot/Ctrlsys apps, they're unusable for me... I think maybe it's compatibility issues?

My calculator seems to return to the latest backup (from shift+mem) automatically though.

I just tried this. I created a backup and then proceeded to do the same thing that crashed the calculator. After reboot, the calculator did not automatically restore the old backup even though the backup was there. I restored the backup manually but it didn't restore any of the programs that were installed. The only things that was restored were things like cas settings, name of calculator, etc. Is it supposed to restore everything installed?

UPDATE: There was actually something wrong with the calculator. I thought it was normal for the calculator to reboot when it gets restored with a backup, but after rereading victorvbc's comment, I realized this shouldn't be the case. I then noticed that the calculator was crashing during the restore process. Apparently, it's possible to format the C drive of the calculator. I entered into the diagnostics page and did just that. Luckily, the problem (cannot cannot restore after a crash) seems gone.

UPDATE 2: There was actually nothing wrong with the calculator. The same problem reappeared. So, I started installing app by app, backup and restore. I think I've found the culprit.

For some reason, even though the Control Systems app by Hata installs fine, if you back up the calculator with the app installed and then try to restore, the calculator crashes. This doesn't happen on the emulator. I hope others can try it and confirm.

Is this on the latest "public" firmware, or the Beta one?

Although I work for the HP calculator group, the views and opinions I post here are my own.

I have tried it on both. With the public release, when you try to restore from a backup on the calculator, the calculator crashes and then reboots with everything wiped. With the beta firmware, the restore process just freezes and you need to manually press the little reset button on the back.

Please note that this only occurs when the backup is in the calculator. If you try to restore from a computer, it works fine. So, if you want to replicate the issue, make sure you do it on the calculator.

I hope you can check it out and confirm it. The link to the offending app is in my previous post.

Did you manage to check the issue on your device ?
