This zip is compatible with ls998, us998,
This zip is created from the original KDZ. It contains almost the complete 20H firmware, but the partition table rewriting part and recovery image (beside five to eight other images) is removed. I changed the system.img, so you do not have to reinstall TWRP (recovery-from-boot.p deleted) when ROM once booted. I also changed the partition size of system.img, so the vendorized people can install this too without having problems because of a too small system partition.
- Stock build made from official KDZ
- System.img modified to keep TWRP
- Resized system.img (for Treble users)
- Removed dm-verity
- Removed rctd (LG's root checker tool daemon)
- Removed ForceEncryption
- Added DTS prop to enable DTS
- Added all weather lockscreen prop to enable other weather
- Unlocked Bootloader [How to do]
- Working TWRP installed (should be installed already, otherwise you wouldn't need this zip [Link to newest unofficial TWRP]
- When you need Root, Latest Magisk [Download]
- [The zip!]
When you are still on Nougat
you should start fresh: Reboot to recovery using button combo or reboot app (needs root; btw, Magisk offers this possibility too: Modules Menu then click three dot menu top right - Reboot to recovery
Then flash [this latest TWRP.img] via image flashing function in TWRP, reboot to recovery again (for fully working new recovery) and do a backup, then copy this backup to your PC.
Then initiate a factory reset. Wipe your system partition too in TWRP advanced wiping menu, copy the 20H firmware zip to your SD and install it. Reboot and enjoy
For clean install: Factory reset and wipe system
You can also keep your data by simply dirty flashing the zip.
*Be aware that problems may occur, maybe you need to do a factory reset to start fresh*
Flash the 20H zip, then Magisk zip when you need root, then reboot to System = you're DONE
If the first time you boot to system, it could be TWRP says No OS installed. You can ignore it.
If TWRP asks if you want to install SU, hit no (in newest TWRP SU is disabled, and the option to install the TWRP app is disabled too.)
Rom Version: 8.0 Oreo
Android security patch level: 2019-3-1
