For example the ones that often flash the rom of a 34s, did you ever have the internal memory corrupted somewhere that let the calculator be not fully working anymore?

My experience of calculators with memory problems:

• TI-58C bought nine years ago and used occasionally; its RAM stopped working completely. Replacing with a new RAM chip (still available, amazingly enough) fixed the problem.
• HP-25C - RAM failed. Would still do calculations but not store numbers or run programs. "Fixed" it by adding Panamatik's upgrade chip.
• Sinclair Enterprise Programmable - looks beautiful, does calculations slowly and not very accurately, but doesn't store programs. It looks too nice to risk disassembly!
  

I flashed my WP-34S many hundreds of times (literally) and never had any memory problems with it.
