Yesterday I thought I bricked my phone. I too also got stuck on the secure boot error 1003 boot loop. It happened when I tried to relock my bootloader with fastboot oem lock. Can anyone explain why that happened and if, after you obtain root, if it's possible to go back and relock the bootloader. I was attempting to get android pay working again, plus it flashes that message about having an unlocked bootloader. Is it possible to re-lock the bootloader after you have root, and if so, what did I do wrong. I finally restored back to factory using the lg bridge tool and download mode, which was a [email protected]#% to get into with a bootlooping phone.
Thanks in advance.

To answer your question, when you root the g4 on marshmallow using chainfire's systemless root, It on the fly flashes a different boot image, thus if you relock the bootloader after rooting the device on the 6.0 marshmallow firmware it will end up with the security error because the boot image has been "modified" and a modified image won't be allowed to boot if the bootloader is locked so the answer is unfortunately no you can't have a locked bootloader and have root at the same time, If you want to relock the bootloader on the 6.0 firmware to get rid of the boot image showing "unlocked bootloader" you should flash the KDZ for the 6.0 firmware in this case H81120i firmware and then go into developer settings and uncheck enable oem unlocking and also make sure you boot into fastboot mode, you can do this via the adb shell. another option to not have the "unlocked bootloader" show every boot would be to go back to the 5.1 firmware which did not have this. I hope this helps.
Thank you for a great explanation.
If you ask the people at xposed modules they may be able to do something maybe....
5.1 still displays bootloader unlocked message.

I have installed h815 KDZ files using LGUP. When i reboot it still displays Bootloader unlocked message. I can not use bootloader unlock/lock guide as I have bootloader unlocked.
Any other means to get rid of the message.
bump for way to relock h815
Although my bootloader is unlocked I have no way to boot to recovery, flashed Chinese stable from vendor after fastboot check for unlocked bootloader. Is this to be expected or has something changed?
Thanks

Flash stock firmware, once you boot stock, go developers options and enable oem unlock
cannot go back to stock rom... phone locked frp locked, not possible via fastboot to unlock device anymore.
booting into phone is also not possible. and firmware downloading via erecovery failed.

You could up grade your Phone vía dload o sdcard, when you put the firmware in the sd or internal, it auto flashes, Just flash the signed firmware for your device
Hi,
Recently I updated my EMUI firmware via the official OTA system.
I had the bootloader unlocked prior to installing the update however afterwards the bootloader was locked. I have verified this in Fastboot.
I wish to flash Magisk on my P9 Plus, however, I have a bootloader unlock code (back when Huawei gave them out freely) however I don't want to unlock the bootloader as it will factory reset (I spent a long time setting everything up).
I tried flashing a TWRP image however the bootloader prevents it as it is not unlocked.
The only other method would to boot the custom recovery image however when executing fastboot boot recovery TWRP twrp-3.1.1-1-vie.img it gives FAILED (remote: Command not allowed). I had noticed this inability to boot images even when I had the bootloader unlocked (I did not want to overwrite the stock recovery or eRecovery for easier OTA updates).
I have the Chinese variant of the P9 Plus : VIE-AL10 Full Netcom Edition.
Is anyone else having this problem? Please let me know if or how to fix this.
Thanks
It's been a while since I last used fastboot boot but if i remember correctly the command is "fastboot boot recovey.img, without that" recovery" in between
if the bootloader is locked you cant flash magisk or any other, also you cant boot with any images
I've got stuck in this situation by flashing the stock rom using the Mi flash tool and locked the bootloader. I am able to get into brom mode and use the SP Flash tool but flashing the stock rom again results in the same bootloop. Is there a way to unlock the bootloader using the SP Flash tool or something else? The Mi Unlock tool doesn't work as the device isn't linked to my account.
