Trying to tether-boot iOS 13.5 on iPhone 7, but it fails every time with this: ./pyboot.py -q ~/Downloads/iPhone_4.7_P3_13.5_17F75_Restore.ipsw iPhone9,1 -a

I checked that folder, Fugu is there.

Also first time it ended with error: usb.core.NoBackendError: No backend available, but luckily I quickly found in #51 that it needs libusb that can be installed with brew install libusb

Okay, got through that error by modifying resources/pwn.py: Line 183: if os.path.exists("resources/Fugu_8010/Fugu"): to if os.path.exists("resources/Fugu_8010"):

Now getting a new error:

Got through that too by deleted the whole "if" statement at line 431 and line 483 and set A10A11Check=true manually in pyboot.py (of course it isn't a solution, but a very quick workaround)

After that I got error:

  Referenced from: /Users/kushwavez/Downloads/PyBoot/resources/bin/irecovery
  Reason: image not found

-> Fixed by installing libirecovery : brew install libirecovery Next:

After that the device started to boot, but unfortunately stalling with

hfs_mountfs returned error=22
mount(x)

After tenth or so try it restart itself, returning to the installed iOS 14.4

New try, iDevice hanging with "Still waiting for root device", need to force-reset

EDIT: Now trying Divisé EDIT2: Same with Divisé:

[...]

Restoring back via iTunes now. Do I need some special bootargs for a successful boot?

EDIT: Looks like AMFI patch is needed. Need to compile liboffsetfinder64, but the compilation fails. Will look into it in my free time.

EDIT2: AMFI patch always fails. Needed to replace bin/Kernel64Patcher with this Kernel64Patcher, after that the patch completed and the device started to boot. However new issue, now that AMFI out of the picture:

[...]
Emergency: Boot task failed: fsck
Emergency: Shutting down in 3 seconds

I gave up and restored 14.4 via iTunes. Waiting for Ramiel to release. That'll hopefully fix all these issues.
