Last updated : 6/5/2025
Changelog :
6/5/2025
- Initial creation

Pre-debloat (i dunno, probably better than letting system consume too much resource for nonexistent tasks?)
- Telemetry : Settings > Privacy > Trust > LineageOS statistics > untick "Stats collection" (only if this isn't offed in setup wizard)
- updater : Settings > System > Updater > 3-dot menu > Preferences - set autoupdate check to never, disable mobile data warning
- cell broadcast (optional) : Settings > Notifications / Safety & emergency > Wireless Emergency alerts - disable everything (can be offed before or after debloating; but not after adb)
- Emergency SOS (optional) : Settings > Safety & Emergency > Emergency SOS - untoggle "Use Emergency SOS" (can be offed before or after debloating; but not after adb)
- Do Not Disturb : Settings > Notifications > People - set Calls & Messages up so no one can interrupt DND (if you don't use the device as a phone like I am; do before debloating)

Skipped NikGapps packages : GoogleContactsSyncAdapter, GoogleCalendarSyncAdapter, DigitalWellbeing, GoogleMessages, GoogleClock

Additional notes : 
- This build of LineageOS seems to be a vendor_boot ROM (not that either of us TWRP recovery ramdisk flashers would know it, at least until the fact showed up in the TWRP logs as I flashed FakeDreamer with susfs), though in practice TWRP flashing seems to still flash the ROM. skkk's TWRP has mountrw toggle in the mount options, which should have skipped all needs for the mount -o commands we would otherwise need in the X3P (or others that don't explicitly mount them as rw). However, for this build of LineageOS, the toggle in skkk's TWRP doesn't reliably work, requiring the terminal command. (https://gearjail.(codeberg.page / neocities.org)/mountrw.html)
- Boot animation is in /product/media if there's any need to change it. There's 2 files - bootanimation.zip & bootanimation-dark.zip - you can either stick with one bootanimation.zip or replace both.
- LineageOS's DocumentsUI goes to Downloads by default, unlike A11. One "workaround" for this issue were replacing the DocumentsUI files with the ones from something like DivestOS (from X3P's A12L build); though any A12L DocumentsUI that doesn't go to Downloads by default works - good luck finding A12L builds that does these though (other than the missing DivestOS and some CorvusOS builds from Pling?).
- Camera2 as default camera. Yes, the AOSP Camera app. The too-barebones camera app that demands internet access for no reason. At least this time it isn't MIUI camera, but I have even less hesitation to just nuke it for GrapheneOS Camera (I would've used OpenCamera but the F3's owner requested the final camera app to be neither Camera2 or OpenCamera).
- Conclusion : It's... LineageOS with GApps? What else am I supposed to say about this? Owner's already daily driving this.
...fine. We didn't have much to say on LineageOS because unlike crDroid it doesn't force-spoof our device without our consent.
