A few months ago I posted a
BwE Complete PS4 NOR Removal Guide followed by my
BwE PS4 NOR Comparator, and today's Tutorial covers a lesson in corruption repair on
PS4 NOR Repairs by
Better Way Electronics.
Here in my favourite example we have a dump that does not boot, is ultimately displaying signs of a BLOD but when the dump is validated it shows the following results:
Code:
UNK Dynamic PerConsole Section Filler 2: ✔
UNK Static Section 1: 000000 [DANGER]
UNK Dynamic Section 20 (SKU Byte): 00 [DANGER]
UNK Dynamic Section 21: 0000000000000000000000000000 [DANGER]
UNK Filler 4: ✔
UNK Dynamic Section 22:
00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 ✔
UNK Filler 5: ✔
UNK Dynamic Section 23:
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF [WARNING]
Well large blocks of 00 is obviously not good, but what about the UNK Dynamic Section 23? Well I give this area (and the areas below it) WARNING's as it generally has blank spaces sporatically throughout its section. So no big deal! I just can't explain why there are blank spaces!
The real issue is the UNK Static Section 1 and UNK Dynamic Section 20-22. Hence the DANGER output!
If you were to open this dump in a hex editor (I prefer HxD) you would see from 0x1CE000 to 0x1CE1FF (A length of 200) you would see this:
Now this corrupt dump is a CUH-1001A on version 6.20 - If I were to look at a similar dump, with similar specs I would see:
Its quite clear what the solution is! Copy this data from the working dump into the corrupt dump! But Should I?
Well luckily the above static section and dynamic sections that were corrupt are GENERIC. This means they are not tied down to a specific console or even version.
To explain a bit better, here is a quick run down of the possible results for the corrupt area:
The possible outputs for the UNK Static Section 1 are only going to be 0007FF (Unless you are stuck in IDU mode, it will be 0107FF - which I consider a 'DANGER' output). So its quite obvious that there is no other replacement for this corruption!
The next area is the UNK Dynamic Section 20, it is a bit...
