Tell us about your setup:

  1. What iDevice are you using? iphone 8
  2. On what version of iOS is it? ios 13.3.1
  3. What version of checkra1n are you using, and GUI or CLI? checkra1n 0.9.8.2 beta GUI
  4. What is your host system (OS version? Hackintosh? VM? etc.)? MacOS High Sierra
  5. How are you connecting to the device (USB-A? USB-C? Apple/3rd party cable? Through a USB hub?)? Anker Cable

What are the steps to reproduce the issue?

  1. I wanted to enter no substrate mode to delete a faulty tweak because it rebooted my phone and now I am in an unjailbroken state.
  2. I went to go into no substrate mode and then while its booting it appears with -20 error ...

What do you expect, and what is happening instead? I want to be able to go into no substrate mode to delete the faulty tweak but i cannot.

Does the issue also occur if you enable Safe Mode? No idea

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

I used an iCloud locked iPhone 8 Plus with 13.4 and Checkrain 9.8.2 on OS Catalina MB Pro with original USB cable.

The iPhone was rooted with untethered iCloud Bypass by AppleTech752 and had substrate and substrate safe mode as tweaks installed on the 13.3.1 IOS version. I forgot to delete the tweaks and restored the iPhone to IOS 13.4. and now it's not possible to Ra1n the device.

I tried to flash the device several times with 3uTools but can't figure it out. Any idea to fix?

Okay the new 10.1. Version of Checkra1n fixed the issue.

@koosues when you say "Safe Mode", do you actually mean the checkbox in the checkra1n options?
