#                   WARNING! WARNING! WARNING! WARNING!
**This is an experimental feature, do NOT proceed unless you understand what you're doing.**<br/>

**PixelFlasher** can create a downgrade patch by utilizing AVBTool to patch SPL value of `boot.img` from the downgrade firmware and match the current SPL value.\nThis would allow a downgrade, however even if downgrade is successful, the phone might not operate optimally or at all.<br/>

### How to get the Current SPL value
  - **Option 1:** If the device is already rooted, and root access is granted to adb, PixelFlasher can extract it from the device.
  - **Option 2:** Extract and select the `boot.img` file of the currently running firmware so that PixelFlasher can read the SPL value.
  - **Option 3:** Manually specify the SPL value. (Format: YYYY-MM-DD) Example: 2024-12-05.

### How to get the target `boot.img`
  - The target `boot.img` will be automatically selected from the currently processed and selected firmware image in PixelFlasher.

**PixelFlasher** can create a patch by using different extracted images.<br/>

This is a summary of what each rooting system typically patches.<br/>

- **Magisk** patches the ramdisk in `init_boot` if it exists, otherwise it patches Ramdisk in `boot`.<br/>

- **Apatch** patches the kernel in `boot`.<br/>

- **KernelSU**, **KernelSU-Next**, **SukiSU** and **Wild_KSU** (non LKM options) patches the kernel in `boot`.<br/>

- **KernelSU LKM**, **KernelSU-Next LKM**, **SukiSU LKM** and ** Wild_KSU** patches the ramdisk in the following priority order:
  `vendor_boot/ramdisk`, `vendor_boot/init_boot`, `init_boot/ramdisk`, `boot/ramdisk`<br/>
  _**Note:** Due to a bug in KSUN which fails to detect root, for the time being PixelFlasher_
  _will prioritize init_boot over vendor_boot until the issue is addressed in KSUN._<br/>

- **Custom** allows you to select any image to patch.<br/>

Depending on the selected rooting option,
PixelFlasher will offer available choices and recommend the best image for patching.<br/>
Unless you know what you're doing, it is recommended that you choose the default suggested selection.

**PixelFlasher** can create a patch by utilizing different methods.<br/>

This is a summary of available methods.<br/>

1. If already rooted, and root access is granted to adb, PixelFlasher can utilize magisk in /data/adb/magisk (core Magisk) and create a patch without user interaction.<br/>

2. If Magisk application is not hidden, PixelFlasher can unpack it and utilize it to create a patch without user interaction.<br/>

3. PixelFlasher can programmatically control (using UIAutomator) the user interface of the installed Magisk and click on buttons to create a patch.
This method is not supported on all phones, and is prone to problems due to timing issues, screen being locked, or user interacting with the screen while PixelFlasher is creating a patch.
This method is usually not recommended.<br/>

4. PixelFlasher can transfer the stock file to /sdcard/Download/ (can be customized), Launch Magisk, and prompt the user to select the file and create a patch.
PixelFlasher will wait for the user to complete the task and then hit OK to continue.
This method involves user interaction hence it is also not recommended, and it is only kept for power users.<br/>

5. PixelFlasher can create a patch from a Magisk App (apk) that you select and provide without installing the app.
This is handy when you want to create a patch using Magisk that is different than what is currently installed.
One common use case would be when you want to create a patch with an older version of Magisk.

Depending on the state of your phone (root, Magisk versions, Magisk hidden ...)
PixelFlasher will offer available choices and recommend the best method to utilize for patching.
Unless you know what you're doing, it is recommended that you take the default suggested selection.
