About the project

Sony Stock Patcher is a minimal and easy transition from Sony's Stock ROM

(flashed directly from an FTF for example) to a modifiable ROM that can be modded as you like.

Built out of my evolutions of libbootimg for MultiROM to support Sony ELF bootimages,

a custom modified kernel based on Sony's copyleft with a minimal set of needed custom changes,

and an automated installation process to patch completely a Stock ROM,

this will allow you to use the Stock ROMs as you wish to.
​

Relevant features of Sony Stock Patcher

Using my Sony ELF 64bits port to libbootimg, Stock boot partition is automatically converted

Modified copyleft Stock kernel to support alterations and remove limitations

Patches the ramdisk to disable automatically Sony RIC security

Patches the fstab automatically for verity

Injects my init_sony project used on Sony custom ROM projects

Supports making the ROM usable as secondary MultiROM

List of changes made to the kernel

Disable Selinux trap security (allows to boot with stock ramdisk sepolicies)

Disable Device-Mapper verity (needed for example to patch system partitions)

Disable kernel modules forced validation (avoids failures on modules signature)

Disable coresight (unneeeded and irrelevant, just to avoid unsupported error logs)

Disable Sony RIC security (needed to use a recovery and alter /system, /data, ...)

Inline kernel modules compilation (to avoid kernel installation fragmentation)

Clearpad touchscreen updates for MultiROM UI

Minor kernel updates
