I hope it's nothing hardware related. It would suck is most HP Prime calcs were defective. Also gogogoluke apparently never had a single issue with his calc but I have yet to see an advanced game program from him, those of which, combined with USB transfers, are usually prone to causing stability issues

A Portugese-speaking TI-Planet user got the same problem as me yesterday :
- did update to the latest 10077 firmware
- did convert images/PDF using both available formats (programs  + applications)
- did use them on the calculator
- now the calculator doesn't boot anymore
- reset+[Symb] is unable to wake up the calculator to put it into recovery mode either

So it really seems there's a problem with firmware 10077, at least in the context of RAM-greedy-programs.

I did see another post on HP Museum where an user reported the same issue I think, but I don't know if it's the same person or not.

I don't know if the bug is due to fatal flaws from previous firmwares causing the new firmware to brick calcs or if it's just the new firmware that is at fault, but it's definitively something that HP needs to fix as soon as possible. Else it's their loss, because if the firmware is popular, especially during Back to School, then they'll have a big lot of calculator returns from customers and lots of replacements to give away, so it's in their best interest to fix this ASAP. Plus many people will just give them bad reviews anyway.


So that makes it 4 bricked calcs under this firmware so far, right? Two on TI-Planet and HP Museum, if I recall correctly. And there aren't that many HP Prime users on the Internet.

Maybe a 3rd one on TI-Planet too, but the user didn't confirm me about reset+Symb this time.

That would make 3+2=5.

DJ Omnimaga

Darn. If there are like 100 active HP Prime users on forums, then this means 2% bricked their calcs or so. >.<

@critor do you know which hardware revision those calcs were and which ones were prototypes or not?

Well, should I use my calc anymore till a patch comes out for fear of bricking?

It depends of certain factors I think. Maybe @critor knows what increases the risks of calculator bricking in particular? I seem to recall that USB transfers of very large files (2 MB?) can cause data corruption and eventually lead to such bricking. So far I haven't gotten any issue with smaller files, but the largest I ever sent was your game and it was an app. The largest program I got on my calc is under 200 KB.

HP has put the old calculator firmware back online: ftp://ftp.hp.com/pub/calculators/Prime/

I don't know if it's possible to downgrade, though. I wonder if anyone ever tried?

I was a bit worried the connectivity kit did because I found it odd that a new kit has to be released for every OS update.

Yeah, I was unsure if HP had anti-downgrade protections or had setup their newer connectivity kit softwares to not support older OSes. I'm glad they don't have any anti-downgrade protection, especially with what's happening with OS 10077 right now. I personally will probably downgrade back just in case. I had no issue with 10077 personally, but we never know.
