Getting either error 79 or stuck in "Setting up the exploit (this is the heap spray)

[williamcll]

Tell us about your setup:

1. What iDevice are you using? iPad Air 2 WiFi
2. On what version of iOS is it? iPadOS 13.4.1
3. What version of checkra1n are you using? 0.10.1 Beta
4. What is your host system (OS version? Hackintosh? VM? etc.)? Ubuntu 20.04 LTS
5. How are you connecting to the device (USB-A? USB-C? Apple/3rd party cable? Through a USB hub?)? I have tried both the Front USB 3.0 ports and the Rear USB 2.0 Ports using the cable that came with the package, neither work.

What are the steps to reproduce the issue?

1. Start
2. Connect ipad to PC to front USB 3.0 port and run checkra1n.
3. Enable Allow untested versions, safe mode, Verbose Boot, Dark Blockchain
4. Enter DFU mode according to the instructions given by the app.
5. Checkra1n loops at "Setting up the exploit (this is the heap spray)" message
6. Unplug cable, reboot iPad after repeated loops.
7. Plug into rear USB 2.0 port
8. Run Checkra1n, Enable Allow untested versions, safe mode, Verbose Boot, Dark Blockchain
9. Application goes into booting, ipad shows the splash screen with words on the top left corner.
10. USBMUX error (Error code: -79) appears and the ipad reboots back to normal.

What do you expect, and what is happening instead? I was expecting the root to be successful after switching from the 3.0 port to the 2.0 port and enable safe mode, however, I run into the -79 error instead.

Does the issue also occur if you tick "Safe Mode" in the checkra1n options? Yes to both USB 2.0 and 3.0

Any other info, error logs, screenshots, ...?

Seems it might be a duplicate of: https://github.com/checkra1n/BugTracker/issues/1168

Seems it might be a duplicate of: #1168

It's not, #1168 is about stage-3 incompatibility with updated kernel, and here it looks like the @williamcll is not getting to component-3, but is stuck in heap spraying.

Would the unofficial version work?

Any updates? I will try the new beta

It's not the ryzen, I've tried on 2 intels and ione ryzen and get the same error on them all. The problem is the Ipad air 2, it will throw that error 79 usbmux each time. I've tried safe verbose and every single options available but it will jsut not work at all. Hopefulle, devs will know about the issue and fix it in next release. Thanks !

With the the new bet 0.10.2 I can't even get to -79 error with Enable Allow untested versions, safe mode, Verbose Boot, Dark Blockchain on USB 2 or 3 port.

Tried this with a iphone 6S running 13.5 as well as the aforementioned iPad. I will try on a raspberry pi instead.
