I have dumped every fw from 1.32 to 2.10 on which i currently stand.
I have some ideas that i will be trying but not untill i have aquired a power supply because every idea has a high probability of causing a brick if not successful.
Hardstore's video claimed to successfully downgrade from 1.60 to 1.50 without a problem. After reading a little (because i dont have one) it seems the 360 blows a efuse with every update, and who is to say for sure that whoever wrote that on the wiki is correct?
And the fact that NDT's downgrade test got as far as the ps3 accessing the HDD before failing to blinking red also makes me question the efuse theory. It would seem to me that by the time the ps3 has accessed the hdd that the nand has already been accessed and found ok by what ever is decrypting it. (if you connect the usb of infectus to pc and start the programmer before powering on the ps3 the ps3 will fail at reading the nand and blink red before the hdd is ever accessed)
Who knows though... more testing needs to be done.
