ask the experts
Once the HP 15C LE loses the flash, will it be possible to reload it?
Will there be any viable method to do it or will it simply die when it happens?

If you could reload the flash, it might be nice to do so with the bugs fixed Smile

Good point - the 15LE has the 6 contacts near the battery, same as the 20B/WP34/31, so the code in the machine should be readable and reprogrammable, but surely not easy to do...

Yes, the 15C-LE can be re-flashed, and the SDK HP released around 2013 presumably works fine, but without the 15C LE code, fixing anything is just about impossible, or at least really, really, really! difficult.

With being able to have it working, I'm worth it. I don't care about issues

thanks @rprosperi for reassuring me Smile
