big problem writing a fubu

three days ago i applied the patch that enable the developer menu. then i made wrong settings, and the phone (cx65 fw47) switched off, with a "bip". then every time i tried to switch on it, after inserting the pin the phone switched off with the "bip". so, i thought to write the safe-fubu with password boot, but after a few block there was a crc error and the loader get off. so i charged the battery and tried again, and all appears done, but this time when i tried to switch on the phone it immediatly make a bip, a then... nothing
so i tried to rewrite EEFUL and EELITE (here there are the settings, no?) but it still can't switch on. finally i solved the problem booting the phone in service mode, and then I "upgrading" the fw with wiswup (fw47).

ok, the problem disappeared, but... why the good fubu didn't work? I made some mistake? I always thoiught that all problems of wrong software (except in bootcore area) could be solved by writing the working fubu with v_klay, now i can't be sure to have a everything-happens-i-can-fix solution!

thanks

in most cases the fubu backup will help to repair phone. Why its is not worked for you - i don't know - because your situation require more deep investigation... ...

ok. only a thing: in flasher section, "buffer of the programm", what's this??? when i flashed my dead phone, i selected from addres 0x00000000, it's right?
I was sure that the flash in the phone after flashing it was right, in fact i readed it and compared with the fubu and there was no difference !

however the phone is working.
i hope that this time i was only unlucky...

right!

another mistery: today i saw that i still can acces to developer menu, but the patch isn't installed!!! any idea to destroy it?
