Hints: how to upgrade customized Micron C400 SSDs to the latest generic firmware version

Important notes:
  1. DISCLAIMER: this guide is provided here only "just for fun" for experimental, research and educational purposes without any guarantees (or warranties, responsibilities, obligations, liabilities etc.; even no repeatability guaranteed, as this guide has been based solely on just one particular specimen device, sorry), so use it at your own risk (even more, the so-called "reverse engineering" can possibly be illegal in some areas);
  2. ATTENTION (DANGER): it can result in an irreversible destruction of ALL or ANY data stored on the target device (including the loss of important metadata like device usage statistics, but it's not wise to hope it will heal / recover / restore any worn-out memory blocks / chips or make the device good as new in performance) and, in theory, on some other storage devices -- please back up ALL the valuable data FIRST;
  3. CAUTION: it may even brick your device;
  4. WARNING: moreover, it may void the warranty, if any.
  5. Feel safe & free to enjoy! ;-)
Recently I've got a (somewhat previously slightly used) 128 GB SATA 3.0 (6 Gb/s) compatible 2.5" SSD from the Micron RealSSD C400 series (the label also says: "P/N:MTFDDAK128MAM-1J1", "Firmware Rev: 080C", "H/W: Rev 3"). At first glance, it looked like a generic equivalent of a more popular SSD brand, the Crucial m4 series.
What's interesting with it: what I've got here is really not a generic, but a Lenovo OEM-branded version, and it has a cut-down set of SMART features: only one SMART attribute ("Power cycle count") is available [4.1, 4.2], though still there's some useful info (power-on hours, total number of logical sectors read / written, uncorrectable errors etc.) in the SMART device statistics & SMART error log; fortunately, SMART self-tests are also available. Unfortunately, updating the firmware from the initial "040H" (probably updated by previous owners, see above) to the latest "070H" Lenovo OEM version [1.4] didn't improve the SMART functionality.

More notes:
  1. This SSD supports SATA revisions from 1.0 to 3.0 (1.5, 3 and 6 Gb/s respectively), but as for UDMA, it's max. UDMA/100.
  2. Most C400 configurations (including the described one, and generic ones too) have no thermal sensor, so SMART usually reports a zero (Celsius) temperature (look for the "C400 SSD SMART Attributes (pdf)" document, "tnfd20_c400_ssd_smart_attributes.pdf" file name [2.2]).
  3. Further debugging and internal SSD operation insights can be hypothetically provided by serial console interface (though currently I have no data on the actual pinout & schematics for the current SSD).
So what are the known differences of this sample, compared to the generic (Micron / Crucial*) versions?
  • Firmware (FW):
    • binary microcode image is slightly smaller than the generic one;
    • reduced SMART functionality.
  • Hardware (HW):
    • unknown.
Legend for a 4-symbol (left-to-right) Micron C400 SSD FW revision string (as described in the "c400_rev_070H_bootable_media_instructions.pdf" document from the Micron FW update package version "070H" [1.1]):
  1. "0" (reserved);
  2. minor revision;
  3. type of SSD application:
    1. "0" (standard 2.5" and 1.8" SSDs);
    2. "T" ("Trusted Drive", SED, as defined by TCG);
    3. "M" (mSATA SSD);
  4. major revision.
Usually, software version numbers look somewhat different (e. g., "1.23"); if you want to compare the FW revision numbers and feel more comfortable with usual version numbers, you can easily deduct the FW version from the revision string, e. g.: "0002" → "2.0", "070H" → "H.7" (obviously, when numbers run out, they begin to use big letters in alphabet order).

Regarding the FW updater bootable images, they have the following structure:
  • bootable (ISOLINUX / MEMDISK) CD ISO image ("*.iso"):
    • bootable (FreeDOS) FDD (2.88 MiB) image ("boot/isolinux/boot2880.img"):
      • fwa.img (FW image);
      • dosmcli.exe (FW updater utility);
      • hdpmi32.exe (DPMI extender driver needed by FW update utility to operate);
      • autoexec.bat (containing the commands executed at the start of the DOS environment, as usual);
      • ... misc. other non-interesting files (e. g., FreeDOS system files);
    • ... misc. other non-interesting files (e. g., ISOLINUX boot files).
* Curious findings about the SSD FW updaters (as of the "070H" version): Micron & Crucial packages contain the same "generic" FW image, but not the same FW updater utility version; meanwhile, the same utility versions are shared by Crucial & Lenovo "customized" versions.

What to do (somewhat simplified) for decustomizatiom / unbranding FW upgrade (if you're still interested):
  1. Please prepare a safe environment for the dangerous activity:
    1. please make backups first;
    2. please shut down the system and turn off the power;
    3. check the earthing;
    4. check the UPS;
    5. please disconnect any other SSDs (especially produced by Micron Technology) from the x86 PC used for experiments before playing with the target device (to prevent collateral damage);
    6. please connect the target device to one of the working SATA ports of your system (please avoid the use of complicated interconnections like hubs, switches, concentrators and adapters, e. g., USB ones);
    7. etc.
  2. (Downgrade the SSD FW to the suitable old generic version, if needed).
  3. Upgrade the SSD FW to the freshest generic version.
  4. Reset (reboot) the system.
  5. PROFIT!
Tips (even more):
  1. You can use free tools (for example, your favorite GNU / Linux distribution) to extract anything from CD / FDD image, or even modify them for your personal needs.
  2. No need to waste writable CDs: you can use the bootable FDD image(s) to create a bootable USB flash drive for SSD FW flashing.
  3. The latest known most generic FW version for C400 SSDs is "070H" from Micron (look for "C400 Rev. 070H Bootable Media Firmware Update (zip)" [1.1]; the archive name should be "c400_rev070H_bootable_media_instructions.zip"), which dates back to year 2013.
  4. A one known suitable old somewhat generic FW update version is the one for Crucial SSD [1.2] m4 series, revision "0002" (search for the following archive name: "m4_0001to0002.zip").
  5. A firmware upload (upgrade, downgrade) can be carried out forcibly if needed; please refer to the "--force" option in the help of the FW update utility (please note not every utility version supports that).
  6. Sometimes the SSD somehow doesn't resume back to normal functioning after the FW flashing operations (and simply resetting the device together with the computer after each such operation doesn't help). Maybe it's better to power it off completely (with disconnecting it from all the cables)... or maybe sometimes it needs a high / low format / full erase etc.??? (Haven't tested thoroughly, as I've got only one such unit). And don't forget about the SMART.
  7. Maybe you can just upload a new FW right away (no downgrades) with the old utility (from "0002" / Crucial)? (Haven't checked though, feel free to test).
  8. Who knows, maybe there's some fresh FW updater with uncut "force update" feature freely accessible too.

               This is not part of the ATA specification.
               A given product must support this capability, as indicated
               by IDENTIFY W159[0] being set to one.
    
    --bridge   Sends the firmware data to the SATL bridge. Only SAS devices (e.g. P410)
               containing a SATL bridge chip will support this option.
               If this flag and the [--drive] flag are omitted, the firmware
               data will be sent to the bridge if the firmware file ends with
               the .dlf extension.
    
    --drive    Updates firmware on the drive as opposed to the SAS bridge
               (see the [--bridge] option). If this flag and the [--bridge] flag
               are omitted, the firmware data will be sent to the drive
               unless the firmware file ends with the .dlf extension,
               in which case it will be sent to the bridge.
    
    --identify
                     Will output a hex dump of the drives IDENTIFY data.
                     Must use [-D] to specify the device index.
                     Ex. --identify
    
    --serial-number <deviceSerialNumber>
                     Used when updating firmware or performing a secure erase to
                     identify the drive to update. When updating, can only be used with
                     the [-f] option. Will be ignored if used with either the [-u]
                     or [-D] options.
    
    --bl <bootloader firmware file>
                     Used to update bootloader firmware. Must be used with either the
                     [-u] or [--serial-number] options to specify a particular drive or
                     with the [--ssd-only] or [-p] options to update multiple drives.

  1. Is there any way to backup the firmware of an OEM branded Micron SSD?

    ReplyDelete
    Replies
    1. Until there's some public info on a specific SSD schematics (or maybe some more advanced service utilities), the best way is to try downloading the appropriate firmware (update) version from the OEM vendor's website.

  2. What about 0G09 firmware (Fujitsu)?

    1. All I can tell for sure, is that "0G09" looks older than "070H"; nothing else is guaranteed.

      But you can try to check the generic "070H" update from Micron, if you like.

  3. Absolutely fascinating guide on upgrading the Micron C400 SSD firmware! It's clear you've put a lot of effort into detailing the process, especially for those of us keen on maintaining our hardware. Your insights on the technical differences and the step-by-step process are incredibly helpful. By the way, looking to incorporate a Micron 7450 Max MTFDKCC3T2TFS-1BC1ZABYYR into my setup soon, hoping it's as reliable as the C400 series has been!
