Please release a basic jailbreak tool for iOS12

[bitching]

Dear author:
I just want to delete some annoying sound files located /System/Library/Audio/UISounds.
(such as low_power.caf, photoshutter.caf)
and completely remove the jailbreak tool as Osiris-Jailbreak do.
I do not need cydia or sileo (form chimera/unc0ver), and also the apfs snapshot made by them.
if i use restore rootfs to unjailbreak, the files i deleted will be back.
they might be good jailbreak tools, but are useless to me.
i'm not a developer, i can only hope you to release the full r/w tool you mentioned https://twitter.com/FCE365/status/1120475011649867776
btw, my iphone8+ os version is 12.0.1, which should be fully compatible with your tool.
