So for those who have the same issue, here is the procedure, it should
work with most Pheonix bios
1/ don't call HP if you don't want to loose your time and stay with no
laptop for 4-6 weeks
2/ don't use the last firmware on HP website (F.06), he is corrupted
and will bsod your laptop
3/ download a previous version (F.04 or F.02) bios, it is a windows
.exe file, extract it 1 time or 2 times till you reach the bios file
*.wph
4/ download the crisis recovery diskette stuff
(
http://rapidshare.de/files/30321496/268076.exe or google it to find
another link)
5/ launch the crisis recovery tool, it will generate a floppy with few
files on it, delete BIOS.WPH which is on it and replace with your file
(rename it bios.wph)
6/ remove the battery from the dead laptop
7/ remove the power cord from the dead laptop
8/ press fn+b or win+b (was win+b for me)
9/ while keeping the key pressed, plug the power cord and power on
10/ when it starts to beep and read the floppy, release the key
11/ floppy will be read for about 20 sec, then nothing, do not unplug
at this time, bios is rebuilding
12/ go have a cigarette
13/ if laptop did not stop or reboot alone, unplug the cable and reboot
it
14/ in my case, the laptop stopped alone when it was finished (about 40
sec)
15/ laptop is resurected, takes 5 min instead of the 4-6 weeks if you
call HP
