[LG V30 ROMs, Kernels, Recoveries, & Other Developm] seadersn:
LG-H930 EU OPEN 22j ROM​

Hi!

This Rom is 100% Stock. Most recent TWRP should first be installed. Then you can install this Rom and have Oreo with working TWRP.

This zip is created from the original KDZ. It contains almost the complete 22j firmware, but the partition table rewriting part and recovery image 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. This is a continuation of westwood24's idea and work, I've updated it to the newest fw version and edited it a bit. I followed his idea and made this for users who can not take OTA's because they have Custom Recovery / Root installed.

​

Features

Stock build made from official KDZ

Stock Build.prop

Unrooted

system.img modified to keep TWRP

System image size shrunk for being able to flash this on a smaller system partition, mainly caused by vendorizing

Removed dm-verity

Removed rctd (LG's root checker tool daemon)

Enabled opt-encrypt, it's your choice now if you want to encrypt your phone, it's no more forced. TWRP now is capable of decryption (both AOSP (Oreo only) and stock) since a few versions

How to install

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: Menu -> Modules -> three dot menu top right - Reboot to recovery)

Then flash this 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 21o firmware zip to your SD and install it. Reboot and enjoy :)

From Oreo:

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 occure, maybe you need to do a factory reset to start fresh*

Flash the 21o zip, then Magisk zip when you need root, then reboot to System = you're DONE

At the first time you boot to system, it can 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.)
