Lockpick_RCM payload - Official Thread


Description
Lockpick_RCM is a bare metal Nintendo Switch payload that derives encryption keys for use in Switch file handling software like hactool, hactoolnet/LibHac, ChoiDujour, etc. without booting Horizon OS.

Source: https://github.com/shchmue/Lockpick_RCM
Payload: https://github.com/shchmue/Lockpick_RCM/releases

Due to changes imposed by firmware 7.0.0, Lockpick homebrew can no longer derive the latest keys. In the boot-time environment however, there are fewer limitations. That means the new keys are finally easy to dump!

Usage
  • Launch Lockpick_RCM.bin using your favorite payload injector or chainload from Hekate by placing it in /bootloader/payloads
  • Upon completion, keys will be saved to /switch/prod.keys on SD
  • If the console has Firmware 7.x, the /sept/ folder from Atmosphère or Kosmos release zip containing both sept-primary.bin and sept-secondary.enc must be present on SD or else only keyblob master key derivation is possible (ie. up to master_key_05 only)
Big thanks to CTCaer
For Hekate and all the advice while developing this!

Known Issues
  • Chainloading from SX will hang immediately due to quirks in their hwinit code, please launch payload directly

Haven't tinkered with my Switch for a while, but tried using this tool to get my keys, but all I get when I inject it is a black screen.

I'm on 6.0.0 and AMS 0.9.2

Which version do you use? Try the normal lockpick. Lockpick RCM is only required for FW 7.0 and above.

Okay!

I just tried using the regular Lockpick, and it seemed to work fine, but the keys generated don't seem to have worked. I tried using them for Switch Army Knife and got an error message asking if the keys were right.

the latest Lockpick_RCM doesn't work? that's odd. you might need to update that extremely old version of atmosphere (it's a year and a half old, latest is 2 weeks old), but indeed you're not going to get any more recent keys unless you update your firmware, so that's why SAK is likely having trouble with whatever content you're using it on. I'd suggest making sure Lockpick_RCM, Atmosphere, and your console's firmware are all up to date and trying again (update Atmosphere first or you won't be able to boot new firmware in CFW). Use either Daybreak or normal settings menu to update firmware.

Any word on when lockpick will be able to dump v11? Thank you for all you do Shchmue

--------------------- MERGED ---------------------------

I appreciate the work you do! Is there any word on when Lockpick will support v11? I get errors anytime I try to dump my SysMMC keys.

Thanks!

    @AncientBoi, Yeah, believe you can do PSP games as well. But a Pi5 is much powerful in comparison.

    Not sure about other models of Pi4 but the Pi 4 B with 8GBs OCed to 2Ghz handles PSP really great except like 1 game I found and it is playable it just looks bad lol Motor Storm Arctic something or other.
  • Psionic Roshambo @ Psionic Roshambo:
    Other games I can have turned up to like 2X and all kinds of enhancements, Motorstorm hmmm nope 1X and no enhancements lol

    This looks like one of their premium models, so... $150 :glare:

  • Psionic Roshambo @ Psionic Roshambo:
    To me that seems reasonable.
  • Psionic Roshambo @ Psionic Roshambo:
    I mean since basically all the games are errmmm free lol
  • Veho @ Veho:
    I mean yeah sure but the specs are the same as a $50 model, it's just those pesky "quality of life" things driving up the price, like an actually working speaker, or buttons that don't melt, and stuff like that.

  • Psionic Roshambo @ Psionic Roshambo:
    I think all in my Pi 4 was well north of 200 bucks 150ish for the Pi 4 the case the fancy cooler, then like 70 for the 500GB MicroSD then like 70 for the Xbox controller. But honestly it's a nice set up I really enjoy and to me was worth every penny. (even bought more controllers for 2 or 4 player games.) hmmm have never played any 2 player games yet :(
  • Veho @ Veho:
    Yeah that's what I hate about the RPi, it's supposedly $30 or something but it takes an additional $200 of accessories to actually turn it into a working something.
  • Psionic Roshambo @ Psionic Roshambo:
    yes that's the expensive part lol
  • Veho @ Veho:
    I mean sure it's flexible and stuff but so is uremum but it's fiddly.
  • Psionic Roshambo @ Psionic Roshambo:
    Yeah a lot of it I consider a hobby, using Batocera I am constantly adjusting the collection adding and removing stuff, scraping the artwork. Haven't even started on some music for the theme... Also way down the road I am considering attempting to do a WiiFlow knock off lol
  • Veho @ Veho:
    I want everything served on a plate plz ktnx, "work" is too much work for me.
  • Psionic Roshambo @ Psionic Roshambo:
    lol
  • Veho @ Veho:
    Hmm, with that in mind, maybe a complete out-the-box solution with all the games collected, pacthed and optimized for me would be worth $150 :unsure:
  • Psionic Roshambo @ Psionic Roshambo:
    Yeah it's all choice and that's a good thing :)
