Thank you for sharing a little of your knowledge with us.. hello from Brazil!!

My pleasure! Greetings from the USA! Thanks for the visit!

[@reliablerusty7039]

Jeez... You ask a guy a simple question and he has to put out a whole video about it. LOL Thank you for the detailed answer to my off camera question regarding corrupted firmware and how to correct it.

[@ToltecMerc]

Lol! It just worked out that way!

[@keithsmith7031]

Another great job and knowing where to check for those types issues. PS 5 lives another day, you the Man

[@ToltecMerc]

Thank you very much! Glad to help!

[@albertdavis1882]

Great job! I love seeing the re-flash videos. You’re lucky you have that old back up.

[@ToltecMerc]

Yep, and I am hanging onto that one. I believe the 69GG required a different bios from the 61GG. Well, I'm sure of it actually.

[@brandonkick]

Great video! This will help me! I'm working on a 1215A blu ray edition with a 69GG chip myself. 1 Beep, then blue light for 2 seconds before shutting down. I think, IIRC, I have a short under the south bridge. Which is unfortunate. Those south bridge chips aren't cheap to begin with, and the 69GG is the most expensive of the bunch. Almost $60 a pop. Luckily I managed to get the PS5 for about $150. So risk is low. But I don't want to go trying to replace that southbridge just yet, until I'm very sure it's the wisest path forward.

[@toolsarecool]

Amazing as usual, trusting the hardware assessment and persisting with the software woes! My only correct upfront guess was ‘line filters’ when there was no video after successfully booting 😂😂 Another one in the books, Congrats!! 🍾

[@ToltecMerc]

Thanks so much! That was the first failed HDMI output filter I had seen on a PS5. They seem to be more robust than the filters on the PS4.

[@madhampster]

Wow your level of expertise is amazing.

That’s awesome. If you decide you wanna fix other peoples motherboard, please let me know. I have seven PS5 Motherboard, 2 edm-020,3 edm-033 and 2 edm-030 That needs fixed. You are really good at fixing motherboards. Thanks!

Welcome back, it’s been a while to be honest I hope you can do a dedicated video for your special tools that you use in your repairs

[@ToltecMerc]

Perhaps. Thanks for the visit!

[@Thehustler01828]

Excellent as usual. You had to replace the Mac address for the one where you got the bios from or did you have to rewrite it to the old one?

[@ToltecMerc]

I extracted the MAC addresses from the corrupt bios and moved them into the donor bios. I did the same with the serial numbers. I try to make it as close to the original bios as I can and I don't like to put in MACs from another board.

[@Thehustler01828]

Very nice work. We love your Channel. Kind regards from Hungary. Royal Console Service

[@ToltecMerc]

Thank you very much kind sir! Best of luck in all your repairs!

[@ikramer3508]

Nice work! Question; can the same firmware being copy or clone to multiple console? Say I have functional PS5, I can read the good firmware file, export and rewrite another PS5 that had corrupted bios.

[@ToltecMerc]

It can. You need a firmware dump from an identical type board. For example, and EDM-010 disc edition is a good donor for another EDM-010 disc edition. Its also best to edit the file before install to correct things such as the serial number and MAC addresses. The file will work if you don't correct but there could be consequences to having the exact same MAC addresses on multiple consoles. It's best to pull the needed data from the original bios and transfer the info.

[@banjomaniac]

I'm gonna try and test my PS5 that just beeps, it had a surge, power supply was dead so I replaced it but got a question. When you reassemble these do you do anything to the liquid metal on the chip, I mean do you just clamp it all back together and it's good? I haven't pulled the heat sink yet that's what I wasn't sure about.

[@ToltecMerc]

I always look at the liquid metal. If the console has been used very much, the heatsink and the top of the APU will need to be cleaned and the liquid metal will need to be redistributed.

[@Samsemillya]

Nice work as always. How does corruption occure on these ics?

[@ToltecMerc]

Thanks! I would guess it happens when there is a power failure during a software update. That's just a guess though.

[@johnHAMMOND-l3u]

happy your back with move videos

[@ToltecMerc]

Oh, there is much more coming! I just need some time.

[@John-oo9xu]

Did you flash the nor dump 1:1 on the chip? So no adjustments made.

[@ToltecMerc]

I used BwE software to transfer the MAC addresses and I used a hex editor (HxD) to edit the serial numbers. It was not a straight transfer.

[@John-oo9xu]

@@ToltecMerc BwE is pretty much the same as Ps5-wee tools (free software) right? Didnt have to flash or read a nor myself but gonna start soon for the fun of it. Anyway great video as always. Clean, organized. Good stuff

[@eduardokonstantinides532]

Excellent work, but how did you change the MAC?

[@ToltecMerc]

@@eduardokonstantinides532 you can edit with a Hex Editor

[@ht8256]

Nice video(s) and thanks a lot. I also have an EDM-033 which does have corrupted NOR, could you maybe share the working NOR such that I can modify my NOR with correct infos?

[@johnrazor8720]

What led you to start at the Southbridge? In general, do you have a standard procedure to follow for diagnosis of a PS5? I think I’ve watched all your PS5 videos and beyond the initial determination of “is the PS working or not?”, I can’t seem to see a pattern. Thanks for all your posts.

[@ToltecMerc]

A good place to start with a no power is to connect 12V from a bench supply and see how much current it draws. It should start about 10mA and climb to around 300mA. It will stay there for about 1-2 seconds and then fall back to 10mA. This is the system initialization. If it does not do this, you have a problem with a power rail, South Bridge, NOR flash, SSD or WiFI/BT module.

[@ceejay_gaming9636]

What temperature do you use on your pre heater and your hot air to safely remove ram or southbridge chip on these boards ?

[@ToltecMerc]

I start with the pre-heater on about 120C and slowly raise it to around 200-220C. I use a temperature sensor on the board and wait until board temp is around 110C before I remove with hot air between 350 and 400C from above.

[@ToltecMerc]

Thanks! I can't say I even looked in the direction of the HDMI port. It was, of course, completely dead.

[@jonathansandiford4137]

Good work as always m8. So the flash is totally different from the ps4. You wouldn't have been able to repair this if it was a ps4 if the bwe validator failed all methods to repair, as you wouldn't have been able to use the flash dump from a different console.. I need to start archiving dumps from ps5 consoles now 😅

[@ToltecMerc]

The PS5 bios is different from the PS4. It's good in some ways but it's bad in others. The PS4 had a lot of per-console data in the bios. The PS5 has moved a lot of that data to the proprietary SSD that is soldered on the board. If one of the SSD storage chips containing that info were to fail, you now have a brick.
