Hi everyone, I'm working on unlocking a HGST Ultrastar 7K6000 6TB SAS drive (model HUS726060AL4210) that's currently locked under firmware A519. I’m looking for a dump of the A907 firmware (either full SPI or just the microcode segment) so I can build a hybrid image. I'm aware that I’ll need to merge the A907 microcode with my drive’s A519 adaptives to keep the calibration data intact — I have tools like dd, cat, flashrom, and a CH341A programmer ready. Here’s what I’ve got: - Model: HUS726060AL4210 - P/N: 0F22790 - Current FW: A519 (locked) - Interface: SAS 12Gb/s - Original SPI dump already extracted and backed up If anyone has a working A907 dump from a similar 6TB model (AL4210 or AL5210), I’d be super grateful. This is strictly for personal archival use — just trying to bring some solid SAS drives back to life Thanks in advance! |

Can you upload your SPI dump? Are you aware that most of the firmware is on the platters ("discware")? |

I haven't received my SPI clip yet, so I don't have the dump available yet - but I'll share it once I'm able to extract it. When I first posted this, I actually planned to dump the SPI that same evening - but I later realized that my SOIC clip was damaged, so I couldn't proceed right away. I've got a replacement on the way, and as soon as I receive it, I'll do the full SPI read and share the dump (with adaptives redacted). Thanks again for your help and patience! |

Make sure you select the correct voltage. I'm guessing it's 1.8V. |

Sorry for the delay - I had to order the SPI clip three times before I could get a stable connection. Unfortunately, even after dumping and modifying the SPI (I've tested multiple versions), the drive still doesn't work. If you want, I can share the dumps SPI Orginal with you Also, I noticed something interesting in the SPI: it looks like the drive is waiting for a specific LSI command before it can proceed like it's stuck in a boot loop. Do you think simply connecting it to a Dell server (like an R520) might trigger that and unlock it? |
