So that didnt go very well.
I got the ps3 disassembled and mounted the clip, and thought that everything went well.
Got the ps3 turned on, and performed the update of the flasher without problems. When i then tried to make the first dump the blue flashing lights turned on 1-3-5-7 and then 2-4-6-8 and then back to 1-3-5-7 and so on and so on.
I took the sdcard out and read the log file, which said : "fail to initialize PS3 BIOS"
I then decided to take the machine apart again at try to remount the clip. After i did that i coudnt get the PS3 started.
When i plugged in the power, the red light came on, and when i press the power on button, the ps3 powers on for 3 seconds, and then turns off by itself.
I decided to take it apart again to remove the clip to see if i had a working ps3. But a screw in the metal plate attached to the mobo was unfortunately damaged, so i coudnt remove it
i really tried everything, and that only made it worse. So i guess i will have to get a metal drill and take it out with that. I know this is only my own fault, and i feel so stupid right now. But lesson learned! My powerscrewdriver was set to too much force.
Has any of you experienced the power on scenario i experience ?
