Hi, about a year ago when the JB came out I was updating from 3.41 to 3.50. I have a phat PS3 with no Blu-ray drive. Because there is no Blueray drive it update would get to 72% or sometimes 99% and then crash and restart.
I had tried pulling the HD out at points were it crashed but have had no luck and never been able to get my PS3 out of the loop. Since a year has past I was wondering if there was a cure to get it out of the update loop or any other OS I could get running on the PS3?
I think I still have the JB usb stick somewhere if that helps...
do you have the controller board for the bluray drive?? if you do swap the board onto a working bluray drive or (this i'm not 100% on) use MFW maker to make your own CFW that skips the blu ray check/update. there are others on here that may be able to explain it better and in more detail.
I had the same problem but I fixed it (http://www.ps3news.com/forums/ps3-he...lp-120350.html). You can also fix it by taking out the HDD before the update begins, it will show you an error code at around 20%, it will start a countdown, wait for that to finish (leave the HDD out).
The PS3 will "restart" and ask you if you want to restart the PS3 or install the firmware on a USB by pressing "Select + Start" (make sure you have the update file in the right directory on the USB and it's plugged in first). Put your HDD back in and press "Select + Start", you can either try installing a CFW that doesn't check for a BD drive* or cancel it so you can get kicked back to the XMB.
