    PS5 EDM-031 - Pulsing BLOD - SSD NAND chips never heat up

    PS5 died in the middle of a game and never would boot again. Pulsing BLOD stays on forever but never boots.

    No LM damage. UART gives a generic "APU not responding" error.

    Under thermal camera, the SSD NAND chips stay stone cold. The controller warms, but not the NAND. I have a good 2.5v and 1.8v around the NANDs...

    I don't have a ton of PS5 experience, but I assume that the NAND would need to warm at least a little bit in order to boot...

    So to those with experience, would you expect at least a little heat from the NAND during the boot sequence? And if yes, is a bad controller the likely cause considering NAND voltage is present?

      Best place to source RAM chips? 8GB 820-00850 boards to 16GB or 32GB
      by ugamazing
      I'm looking to upgrade several 8GB 820-00850 boards to 16GB or 32GB for personal use. I am curious what the best practice and process is for sourcing new replacement chips, and what vendor(s) you guys prefer? Another question is, how do I find compatible chips and their corresponding part/model numbers? For example, in the 820-00850 schematic, the DDR chip U2600 model listed (EDFB232A1MA) corresponds to 1x32GB chip. Of course, I would need 4x8GB chips to replace the 4x2GB chips currently on the board. How do I find compatible 8GB chips? Is it as simple as searching "BGA178 8GB 2133"...

      820-00165 pulsing and stuck at S5
      by speggio91
      Hello everyone!

      I have this board that got slightly water damanged and it is stuck at S5 state. It pulses once every 5 seconds.
      When connected the magsafe 2 to the bench psu, the current goes from 0.02A to 0.10A when is pulsing.

      When using the genuine magsafe 2 charger, the light turn on and it became green and then amber. The fan is not spinning.
      When I tried the SMC bypass mode, the fan spins a quarter every 5 seconds and the pulsing is still present every time the fan spin.

      The pulses are present in the CPU Vcore rails on L7320 and L7310....

      WSON8 NEW Bios Chips READ, ERROR, ETC.
      by feherhollo
      Hi,
      I asking for help on some new WSON8 256MB chips. Please share your experience. I faced error on some new chips on read, erase, write with different programmers. These new chips are not exist in any programmers database. (GD25B256D, XM25RH256, W25Q256JV so on.)
      I'm using RT809F V.5.0, EZP2023 Pro, CH341A Green

      For the exact experience with GD25B256DYIG is RT809F erase the chip under 33sec. This kind of 256MB chip normal erase time is 70-120sec so I think not all the partitions are erased. If I do blank check or reread the buffer says FFFFFF but when I write the correct...
