LG Joan H930DS OPEN ESA IND 20f 0517 ROM including new OP partition offering airtel VoLTE​

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. It should be installed only when coming from a previous full original (kdz or flashable fw zip, possibly rooted) firmware for H930DS Plus.

This zip is created from the original KDZ (IND	H930DS20F_00_OPEN_ESA_DS_OP_0517.kdz, this time resulting in the correct version number, because OP partition is included, which at the same time gives you VoLTE functionality for airtel. It contains almost the complete 20f 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.

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 and stock) since a few versions

New version of OP partition included, pls see above :)

Installation

What you need

Unlocked Bootloader [How to do]

Working TWRP installed (should be installed already)[Link to newest unofficial TWRP]

When you need Root, Latest Magisk [Download]

The TWRP flashable zip file (MD5: visible on AFH, it's correct)

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 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 20f 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 20f 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.)

Just give a thanks if you like the zip! :good:
