GNU Guix on iPad2 (A1395)

Context: I have this iPad 2 that I got as a gift from a friend who was upgrading on the newer version to try to get me to like Apple. I hate it and it was in my storage unused for many years so now I am trying to get GNU Guix on it with GNOME.

To achieve this I merged the required packages in guix (https://issues.guix.gnu.org/57902 and https://issues.guix.gnu.org/57871) and thanks to the jailbreaking community i can use Checkm8 exploit([https://github.com/axi0mX/ipwndfu](https://github.com/axi0mX/ipwndfu[12])) to get full write access to the device and unlock the bootloader to boot unsigned OS and linux-libre seems to have all required drivers to run on the device, see the current progress in https://git.dotya.ml/kreyren/kreyren/issues/30

The issue is that i can't get libusbmuxd (the daemon used to communicate with iDevices from Linux) to work on GNU Guix likely due to a configuration error in guix to perform the exploit and install guix, can someone help? https://github.com/libimobiledevice/ideviceinstaller/issues/147

Any relevant info on how to get iPad 2 or other iDevices to work with GNU Guix also appreciated.

Not a real answer, but have you tried contacting projects like
postmarketOS?  They have much more experience with this sort of thing
and might be able to help with configuration issues.

It seems to be guix specific as the usbmuxd seems to work fine on other distros, but has issues on NixOS and Guix thus why asking here

I’ve run into this before.  Guix is currently on libusb 1.0.24, which
has a bug: <https://github.com/libusb/libusb/issues/825>.

Here’s the workaround I use:

;; Use this version of usbmuxd to access an iPhone.
;; Cf. <https://github.com/libusb/libusb/issues/825>.

(use-modules ((gnu packages libusb) #:select (libusb usbmuxd))
             (guix download)
             (guix packages)
             (ice-9 match))

(define libusb-1.0.25
  (package
    (inherit libusb)
    (version "1.0.25")
    (source
     (origin
       (method url-fetch)
       (uri (string-append "https://github.com/libusb/libusb/releases"
                           "/download/v1.0.25/libusb-1.0.25.tar.bz2"))
       (sha256
        (base32 "0j88ym7afy4wj3x789zzxsr04asyjy0mw29gf31blzkrg8cyya4a"))))))

(package
  (inherit usbmuxd)
  (inputs (modify-inputs (package-inputs usbmuxd)
            (replace "libusb" libusb-1.0.25))))

With this, I just use “guix shell -f” to launch a shell with access to
the fixed usbmuxd.

There are 1.5K packages that depend on libusb, so an update will have to
wait for the next core-updates cycle.

HTH!
