Ok, but what I can't understand is why this happened ONLY if you try to flash beta4 or r121 with a CF card ( I did this at the very first time beta4 was downloadable and before this error was described on pdaxrom web site ).
And where are these data written, because I thought that if you came back to original Sharp Rom, problem will be solved.
Is there any other data than NAND you can save/restore in the SL-C3100? ( I saw a HDD Backup / Restore tool in the D+M Menu for example ).
If so, could anyone place here a save from his own data to test ( and how to restore it ).
Another thing : has anyone a sharp rom backup ( original, not the trisoft one ) just to test if it can solve something?
And last : is there anywhere a translation of the buttons of the emergency boot from Sharp? ( I can't read japanese, only french english and german )
If anyone need more information about this issue, I'm ready to post any other information you need and to do any test also.
I think I've got a solution, but I'm not quite equiped yet : flash the Sharp Rom without the Microdrive, then flash to r121 and only after all that done, put back the Microdrive ( I need to buy some very small screwdriver to open my Zaurus ). Will send the results here
