[SCRIPT] Bump script for SuperSU 2.62+ - G2 General

Bump script for SuperSU (2.62+) system-less install mode​What it does:
Shortly: it let's you install newer SuperSU (version 2.62 or later) on Marshmallow ROMs with read-only system partition without issues.
Newer SuperSU installer repacks kernel (boot.img) during installation, so bootloader's security key is lost. This scripts allows SuperSU installer to add it back to kernel before flashing it back to boot sector. No more Secure Boot error!
It should work on any LG device with locked bootloader that supports Bump method (G2 and G3 do).​When to use:
You're on Marshmallow ROM;
You want to flash latest SuperSU.
How to use:
(if older (<2.62) SuperSU is already installed) open supersu app and remove root completely;
reboot recovery;
MAKE BACKUP of boot sector! In case something goes wrong;
flash CustomPatcherScript_Bump.zip;
flash SuperSU v2.62+;
reboot system.
Downloads:
Script in attachments
SuperSU v2.62+
NOTE:
If you use system-less root, you would need to flash SuperSU on every system and kernel update!
Script is stored in /data, so if you format /data (factory reset), you'd need to flash it again.
Have fun! :good:

I've made a flashable zip and updated instructions. Everything work fine for me here!
Btw, it should work for every device with Bump (like G3), feel free to test and report.

Working on CM13 with BETA SuperSU 2.67 (D802).
Thx for great script

---

Is it possible using this script on Cloudy G2 3.3?

---

Didn't work. CM13 05/03 - D802 - SuperSU 2.68.
No errors, but no sign of SuperSU too. I installed by Play Store but don't update binary.

Read the description. You need to FLASH supersu zip file via recovery, not install with play store. If supersu would alternate kernel files somehow and didn't call the script, ROM wouldn't boot at all.

This script is just a helper for SuperSU flashable zip. If supersu flashes in systemless mode, you need it. If not, this script won't be even called (so useless).

---

For me SuperSU v2.68 not working I'm back to 2.67 and everything is ok

I did how description says, but didn't work, so I tried installing by Play Store. I think it's SuperSu 2.68 fault, because blastagator's tool didn't work too, now I'm going to try with 2.67.

---

By "doesn't work" you mean no supersu (app and/or binary)? If so, it's not related to the patcher script here. If you'd flash SuperSU in systemless mode without custom_boot_image_patch.sh in /data, you'd get a security error during boot.
I can't test it anymore, my G2's display is dead. But please try SuperSU-2.69 and look at flashing log. It should patch kernel image AND call "custom_boot_image_patch.sh" ("- Calling user boot image patch script").

See this and next page. On G3 also is some problem with 2.68.

@SimpleX91 Hi man.
I wanted to update supersu then I tried but it failed. My phone got bootloop. Firstly I had supersu 2.52 then I followed instructions except for remove root. Because I cant get into recovery if I remove root( I have installed widget to get into recovery). I did everything else as you mentioned.
My device is LG G3 D855TR Fulmics 4.2 MM
Please help...
