This guide will explain how to jailbreak an iPhone 6S on iOS 15.7.3 using Palen1x on a Windows PC. Palen1x is a bootable Linux environment where you can run Palera1n.
At the time of creating this guide, there are some things to take note of:
This won't work on Virtual Machines
You might run into issues on an AMD Ryzen CPU so use a PC with Intel CPU
For A11 devices, ensure to disable your passcode. You'll be unable to use SEP functionality like your Passcode, Face ID or Touch ID, and Apple Pay till you boot into a stock iOS state.
For A11 devices running iOS 16 on which the passcode had ever been enabled, you'll need to disable it and erase all content and settings (factory reset) before attempting to jailbreak
Palera1n can jailbreak iOS devices with A8(X) to A11 running iOS 15 and higher
Requirements
A Windows PC
A USB / Flash drive / CD / DVD with at least 64MB capacity (its contents will be erased)
Steps to jailbreak iPhone 6S using Palera1x in Windows
Follow the steps below to jailbreak an iPhone 6S on iOS 15.7.3 using Palera1n
Part I
Extract the contents of the Ventoz zip into a folder and copy the Pale1x ISO into the Ventoy folder
Connect the USB / CD / DVD and launch Ventoy2Disk.exe
Choose the storage device then click Install
Type YES when prompted and click OK. Click OK when prompted that the device will be formatted
Wait while the device is made bootable
You should get a success message when done
Your storage device should now be split into two drives, copy the Pale1x ISO into the empty one
Boot into the USB / CD / DVD n your PC (requires a BIOS setting change), highlight the ISO image and tap Enter
Highlight Boot in normal mode and tap Enter
Wait while Palen1x boots
Wait for mounting to complete
Highlight Palera1n and tap Enter
Choose Switch and choose Rootless (We used Rootful for this guide though) then go back
Tap Options
Choose FakeFS if you have a device with at least 5-10 GB free space. Choose Create BindFS if you don't
Tap Start
Connect the device while powered on
The device should reboot into DFU
Once prompted on the device, tap Trust
Tap Enter once the device is in DFU
Follow the instructions (button combination and duration to be held)
You should see Found PongoOS USB Device
The device should display PongoOS
A9 devices might get stuck at PongoOS so tap Ctrl + C , Tap Enter to exit then highlight Start and tap Enter
The device should display an activity log
The device should boot up when done
Part II
Repeat the process with just flag -f i.e You could either reboot and skip the part where you changed options (FakeFS / BindFS) or go under Switch and toggle between Rootful and Rootless. The goal here is to clear flags so you have only -f
The device should boot up again once done. Connect to WiFi and wait for a few minutes. Palera1n should appear in your app drawer
Launch Palera1n
Wait while necessary packages are downloaded, installed and run. Tap close
You should now see Sileo
Important Notice
This is Semi-untethered so you'll have to re-do the part II section each time you reboot the iOS device if you used FakeFS
