If have this tool , Maybe you can skip the bootloader restrictions

In case I can't solve the whole SIM problem I need to get the phone back to my carrier and get it repaired/replaced so I have to get it back to carrier stock and lock the bootloader. But how do I install a ROM extracted from Update Extractor? Maybe someone has the syntax for a batch file to do it?
Update extractor will produce .img files. You need to follow the steps listed in Chapter 4: Unbricking from: https://forum.xda-developers.com/p8lite/general/mega-thread-root-unbricking-updating-t3400994
You will need fastboot (and fastboot drivers if using Windows) installed.
It's up to your provider to decide if they still offer a warranty. Unlocking the bootloader voids the warranty, and re-locking will show that the bootloader has been previously unlocked.
Is there any script to bypass factory reset after unlock bootloader in emui 8?
Or I don't know if there is some apl like odin inorder to flash files with locked boooadee for huawei devices?
And as second question can u use my previous bootloader code (emui 5) to unlock emui 8 bootloader?
Use dload method to flash service ROM. I think there is service ROM for EMUI 8 now as well, at least for the European version of the phone I think, not really sure. The bootloader resets to state "locked". If you relock using "relock" in fastboot, it will show "relocked". And yes, you can use the same code to unlock again, it changes only if the motherboard in the phone gets changed.
I know about dload method and used for upgrade to emui 8
Im going to unlock my bootloader and flash twrp
Im looking for a trick like some OPO script that can bypass data wipe after unlocking.
Hi guys, I am wondering that anyway that I can fully return to stock? And if I return to stock, does it still show the warning of the unlocking bootloading when we start the phone?
Thank guy!

1. Use LG Bridge to "repair" the phone will get you back to stock Oreo and LG OTA updates. But will not relock your bootloader so you still see the code orange warning.
2. To relock your bootloader, read the FAQ contained in the unlocking guide. Essentially it's a fastboot command.
Both steps will wipe the phone so backup your data first.
How to in 5 steps Lock your bootloader ,that worked successfully on (H870)
the requirement for a successful lock: flash with LGUP and uppercut LG STOCK FIRMWARE
1. Enable Developer Mode
2. Enable OEM Unlocking
3. Boot into Fastboot Mode
3. Typefollowing command ---> fastboot oem lock
4. Wait for the Command Prompt to tell you the process has finished
5. And.... ---> fastboot reboot
Your bootloader is successful locked
Why is LG UP / uppercut a requirement? I did it using LG Bridge, worked. The requirement I think is just an LG stock firmware. Pretty obvious.
I also wrote "the requirement for a successful lock: .... " ! you can see colon ? I do not say must take LGUP ,It was a suggestion to note

Yes :good:

How to relock the bootloader after the oreo update ??
i tried skipping the gpt and the bootloader but the boot img is giving the downgrade error.:crying:
Without the Oreo firmware, it won't be possible to relock. You need your GPT, bootloader, boot (kernel), system, OEM and other partitions to be on the same firmware level, else the partition checksums won't match and at best your device won't lock, and at worst you'll boot loop/brick your device.
You'd also need firmware as new or newer than your bootloader to relock, which means the Oreo firmware. I would not advise trying to downgrade your device to lock your bootloader.
I have an unlocking code from Sony but no luck with either Kingo Bootloader unlocking thingy or Minimal ADB & Fastboot - the device menu says NO to bootloader unlocking.
surely that cannot be it?!

Make sure Allow bootloader unlock is enabled in Developer options .
then try fastboot oem unlock 0xENTERYOURCODEHERE
Obviously put your code after 0x BTW (its ZEROx)
or try with xperia flashtool
Xperia FlashTool

If you are sim locked Ur bootloader is pretty much forever locked even if u get Ur sim unlocked afaik
But you can have temp root access via mtk-su
