Few questions regarding G4

Hi guys i have few questions regarding the lg g4 hope u can help
1. How is the bootloader system and how it works in comparision to htc's s-off and s-on cause with htc's if you got some hardware problems u just go stock and s-on voila valid warranty.
2. How broad is the developer base and interest in lg devices as comapred to htc and samsung devices.
3. How broad is the scope for developer support for dual sim g4 variant as this is the one being launched in India (kind of hoping that they will launch the international variant.)
4. Now i know that there are various guides for root and flashing and everything but i just gotta ask this is there some software to be used like samsung's odin
for flashing or is it direct like htc just use cmd.
5. One last question im stuck between note 4 and lg g4 and i am not able to make up my mind between these two so hoping that members with can help me this.
I have used samsung and htc but i have no idea regarding lg never used one so please bear with me.

The bootloader is currently locked and cannot be unlocked. It will take a developer to try and find an exploit to be able to unlock it. With the G3, this took around 6 months. If and when it is unlocked there should be good developer support. There is currently no root methods for the G4,it can't be rooted at the moment.

Tnx for the reply , also how was the support was for g3 both single and dual sim variant in comparision to htc and samsung also could u pls explain what kind of system lg follows like htc has s-off and samsung has knox thing so
can lg systems be completely relocked like htc's (s-off to - s-on complete stock) to use the warranty in case of some hardware defect.

OEM Unlock isn't an option after enabling developer options

I am trying to unlock download mode on my HTC One M9 running 5.1 in order to root, but when I try to get an identifier token from htc via cmd, it comes up with an error about enabling oem unlocker. I've scoured my dev options but cannot find this checkbox. Is anyone else having this problem or know a solution?

Unfortunately with Verizon models, they have hidden the oem unlock options. To unlock/root a verizon model, it must be unlocked via java card or clip. There's a thread with forum members offering their services here: http://forum.xda-developers.com/verizon-one-m9/general/m9-java-card-t3063247
I believe Sunshine also now supports the verizon model : http://forum.xda-developers.com/showthread.php?t=2792487

How to unlock Bootloader. Currently running 2.20.40.183 ZE551ML

I've tried several threads here and none is working.
I did all the downgrade, still not working.
Please help.

Try running the unofficial bootloader unlock tool... I used it on 174 update with no problems... Just remember to have developer settings active and USB debugging ticked...
Remember, unless you like the white ASUS start screen you'll need to flash the normal black bootscreen again using fastboot...

The official Asus bootloader unlock tool is also handy and I think works for newer versions, though if your phone is still under warranty, you can't hide that you've unlocked your bootloader using the official one because it contacts Asus's servers, unlike if you use the unoffical one, you may still be able to keep your warranty, but that's not guarantee. You can always flash the stock black splash screen to hide it in case you need to return your phone for repair.
You can download the official unlock tool here

Can I downgrade Mate SE back to Nougat from Oreo with a locked bootloader?

Been trying to unlock my bootloader to no avail, but on the other hand, I can't seem to find a stock Nougat rom that I can install on stock recovery. Should I just return this phone, get a new one and obtain unlock code before updating to Oreo? Or is there any way to downgrade back to Nougat on locked bootloader?
Thanks.

I think it's possible with hisuite.

There is service rom that will flash with locked boooader, and one that is nougat. But it will leave you with strange build number. But should allow for dc-unlocker to read your code.
I was unaware that some trouble with reading the code in Oreo existed. But just got confirmation in other thread that service rom roll back helped

Thanks everyone, I ended up returning the phone and getting a new one. Read bootloader code from nougat, updated to oreo and unlocked everything no probs.

1. if you help me to FORCE UNLOCK device without need Developer Option in setting my problem will solve
2. If you help me to Bypass Android Welcome Wizard, access setting and enable OEM Unlock
3. If you help me to update the device from Android 8 to Android 9 Verizon ROM via ADB Sideload or Update from SD card in Recovery mode
4. If you have any idea to how can I fix it

Please, someone, help me
My Device SKU: XT1789-05

These coolicool phones always come with the wrong firmware install, the simple solution to that is to flash the correct firmware which is plain old RETAIL. Solved. That's for anyone who might have or end up with one of these phones.
As for your phone and since you're in the situation you are I'd flash VZW pie. That isn't the correct firmware for your phone, but you've got a locked BL with VZW on it now and nothing is working. Since your ultimate goal is to flash pie anyways, that's what I'd do. Maybe that will clean up your system enough to enable oem unlock. If you can get your BL unlocked, then you're half way there. Surely by now you've realized that you haven't got many if any options.

You need to elaborate. Is oem unlocking grey out? Are you signed into google services? Do you have wifi and/or radio?

You shouldn't flash firmware from other variants like att, etc. However, if you're able to flash those firmwares and not get any permission denied errors then your bootloader is unlocked, which is good. If you have NOT flashed a pie firmware, good, do NOT do it until everything is up and running and you're sorted. If you have, then you'll need to use pie firmware to fix it since once you flash a pie modem there is no going back to an oreo modem.
Run this command from bootloader/fastboot mode and post back your output.
