Well this week we have some exciting news that we hinted about last week.
First, a small technical explanation. We were not able to modify any data on the PS3's flash chips due to the ECC. The ECC is a checksum basically, that ensures whatever data is in the block is not changed or corrupted, and if it is it errors.
So, the problem was since when we tried to alter data, the ECC would then in turn be invalid, causing errors, making the system not boot.
We did develop a way around this, however, it was time consuming and quite slow. We used the PS3 to write data to the flash, then dump it, with its proper ECC, then rewrite to where we needed it. This would take hours on end! We were not able to regenerate the ECC since we did not know the proper algorithm.
But now, we can!!
After multiple tests done by NDT to see what the ECC... More »
This is just a short post to let everyone know we're still alive. Its been a quiet summer, most people were off on vacation (or on holiday, for our friends across the pond), including many of our own PS3 Devs.
However, the summer is over and we all went back to work in full force on the PS3, adding some new and very talented Devs along the way who will be helping out!
For starters, our very own ggparallel spent the past month or so along with NDT testing countless edited PS3 Firmwares on the PS3, and has been able to drastically refine our knowledge of the PS3's bootup procedure.
Below is a clear flowchart of the current theory of operation, the basic procedure is the same as we previously posted, that the system is booted in a "chain" so to speak. LV0 loads lv1ldr, which loads lv1.self (the Hypervisor).
Then depending on th... More »
