I was told that you scan down until the FFFFF HEX starts then you should not have any data after where the FFFFF HEX ends. But this so called known good has data before and after. I am using HEXHD. You using Text string or Hex Value for searching 001c?

Okay well i will have a deeper look. Just didn't want to try and reinvent the wheel is we already had the knowledge. Thanks!

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

your missing the point,
your comparing them to find out what is different.
because nobody knows - or they arent sharing what they have found.

i have ONE CFI-1015 dump,
thats all i can find online - nobody is sharing shit because the people doing comercial repairs probably think it's some type of asset.
that or they are scared of sony.

use a hex editor that can DIFF 2 binaries.
maybe 010 editor or imhex

Stj,
I did use a hexeditor and compared the two binaries. But other than model and serial number. What else do i have to change before flashing the chip?

On PS4, this behavior was the same as you have on PS5 (not a working HDMI chip) and the set-top box did not boot to the end.

Lotas,
So you think i have a bad hdmi encoder chip?

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

Okay i just was able to find the model through hex editor on both bin files. The known good is a CFI-1116B and my original is a CFI-1115A. I was told this BIN would work for my EDM-020 board though. Thoughts?

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

Yeah i follow you. Is there any tips and tricks to working with HexEditor? I am not sure what i am looking for in the BIN.

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

compare the 2 flashes for differences.

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

Can you provide me a step by step walkthrough a bit? I have done this with Dell laptop BIOS's. The only main things to change in them BIN files are the Service Tag, Product Key, and MAC. I assume Sony has something similar? I have the W25Q16JV@SOIC8 backed up to BIN. What do i need to edit before flash. Those are the steps I am looking for. I am a noob with game console flashes.

i dont know if it's just the dvd key and maybe a checksum.
if you unplug the dvd you can flash the non-drive syscon firmware and it works

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

Still battling this one. I have all the power rails. PS5 beeps, turns on. Pulsing blue light and no switch to white. But remains on. Thermal camera shows everything running at from 40-50 degrees celsius. APU , RAM, SSD, all warm. I have removed the BIOS chip and backed it up. My friend offered me to remove his bios chip from known good ps5 as well. Plan is to flash his known good bin to my chip. But what do i need to change in Hex Editor prior to flashing? We want to cross all our t's on this process. I need to know where to find the Model, Serial and any other relevant info that will need to be copied prior to flash. Any ideas?

remove and dump the syscon flash,
i'm sick of people asking for dumps so it's time to start creating a collection.

Not even sure the flash i have on this chip was not previously corrupted.

Anyone know what the full part number of this chip is? It is located right beside the buck controller. 1st pic shows buck controller to left and un-identified chip to the right. 2nd pic is un-identified chip zoomed in.

Not able to find a short on this board. This is like a needle in a haystack without a schematic I did confirm no liquid metal spill. Re-applied liquid metal and and same issue.

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020

Update: Removed board and connected to DC power supply. Providing 12 volts and 1 amp current. Looks to be a small short somewhere. This should be fun to find. Haha
