Can the bootloader be relocked with a non-stock software channel? - Moto G7 Questions & Answers

Hello forum, likely idiotic question incoming.
If I was to buy a bootloader-unlockable Amazon Prime or T-Mobile variant of a G7, which I read are spec-wise no different from Retail US models, would it be possible for me to flash an official RETUS image and relock the bootloader? Or would that end in mismatched signatures and a fiery mess?
Thanks.

Purchasing advice regarding variants (MEGATHREAD?)

I am coming from the Samsung line, Note 4 to be exact. I know I will be purchasing the v20, as it is the spiritual successor to the Note 4, to me.
I have been browsing the forums here and doing some reading, I see that the v20 is in it's infancy with root/developers breaking into nougat.
I try to find some answers, and I am unable to fully relinquish all my questions.
From what I understand the American models have unlocked bootloaders via Dirty Santa method, and two korean models if I am correct.
My questions are, which model should I buy? I want to have the model that has the MOST developer support. As I have the Exynos Korean model of my Note 4, and the development/custom roms and the like for my model are pretty non-existent, and it sucks.
From what I've read so far, if you want root, unlocked bootloader and the like, to steer clear of Dual Sim v20's. If this is true, what is the reason?
I was looking on the LG site and saw they are offering the US996 (unlocked) with a 200gb SD card.
(http://www.lg.com/us/cell-phones/lg-US996-Unlocked-v20-titan)
Does 'unlocked' mean that it is SIM unlocked or Bootloader unlocked?
If it's just SIM unlocked, is there ANY model that has Bootloader unlocked from the factory? (and will it have the support of developers, with custom roms and the like?)
Or is the US996 my best bet at unlocked and most widely supported v20.
Lastly, I see there will be a Turkey model release, international sim.
Should I wait around for these other v20's to pop up before purchasing? (I am in no rush to upgrade from note 4, but excited for new v20.)
Thank you everyone for your time in reading this.
I hope this thread helps all newcomers who want to hop on the v20 train.
TL;DR - What is the best model phone to purchase, that will have most DEV support?
The US996 model can be bootloader-unlocked directly from LG.

Right, I saw that! It says it voids manufacturers warranty though. So what if I purchased another variant and unlocked bootloader and sent it in if I messed it up. Would it be a possible gamble of them fixing it vs them knowing my phone is bootloader unlocked because I officially unlocked it via website?
Or should I just purchase based 3rd party warranty, (such as square trade) and not worry about it?

Amazon G4 - to unlock or not?

So I just got an Amazon G4 32GB w/Ads running 6.0.1 (XT1625 ). Out of curiosity, considering everything I've seen that says they're locked anymore, I went to the Moto site & submitted my data strings and evidently I have been sent a unique boot loader unlock code. Should I unlock and see about installing another ROM, or should I just go with the Amazon variation of the software? I get that the general consensus of this site is for flashing alternate ROMS...but I'm just concerned about bricking this phone since it is the Amazon subsidized version.

Definitely unlock it if you can. It's generally very hard to brick this phone unless you break a bootloader/fastboot flash.
Custom ROMs are leagues better than insecure Amazon firmware and ads.
Can the Amazon subsidized G4 be unlocked if it's been upgraded to Nougat? If not, is it possible to roll back the version?

H870DS prices have or are tumbling. should I?

I see the G6 H870DS HK or TW version (parallel imported goods) for about 360 USD.
Pretty good price I think, however the situation with the locked bootloader is making me apprehensive in purchasing it.
I read that the EU version can be unlocked right now via their website, but nothing with the Asian DS versions.
My question is what's LG record WRT unlocking their bootloaders? Did it happen with LG5, V10, V20 Asian versions?
Should I just purchase now and HOPE they will unlock it?
Tks in advance
No. If you absolutely need an unlocked bootloader, don't buy the DS. It's superior to the regular G6 in every way, save the ability to root.

Bootloader Unlockable!

Greetings,
Since I cannot afford to buy a V30, I decided to buy the V20 but
at the moment I hear some V20 variants are no longer "Bootloader Unlockable"!
Can someone please tell me what version / model number I can buy that
its bootloader is unlockable?
Thank you.
unlocked US996 -- guaranteed that you can unlock the bootloader, and have all fastboot commands.
Baring that, the only other model that is guaranteed rootable even on the latest firmware (which just came out) is the H910 (AT&T model).

LG G6+ US997U LTE Bands Unlock

I am planning to buy an LG G6+ US997U(Model no LGUS997U.AAMZBK) and import it to India for the simple fact that US997U models are bootloader unlockable.
The problem arises that the LTE bands being used in India are not mentioned in the FCC filing for US997 models.
As I understand the modem in SD821 supports all LTE bands and there are region specific software blocks to block other bands.
My question is whether after unlocking and rooting, I can remove those blocks so the phone works fine with the LTE bands in India.
Please Help.
you know only the H870 and US997 can be unlocked no other models like the h870d or ds or a u version
..but DS is quite different. (two sim) 997 and 997U are differ just in mem size and quad dac. So the boot is almost the same.

Yes I read in an Amazon review that there is official support for bootloader unlock for US997U.
Question now is whether I can unlock all the LTE bands available with the SD821 and whether I can flash the H870 or US997 recovery and roms(Lineage, AquariOS) on US997U?
 @J0SH1X @rc420head Can you guys help answer this please?

Absolute nothing. No custom rom, no recovery, no root. ...and I think no system updates too for u, because it is an Amazon branded phone.
So... Is the G6+ (US997U) supported by LG Developer's bootloader unlock, or not? That's the real issue... not the fact that it's "just the memory size" because LG distinguishes support based on the IMEI/MEID. Consider the fact that all of the US99x phones are the same model number for the "unlocked" and the "US Cellular" versions... but LG will not send you an unlock code if you attempt to use a device ID from a device that is provisioned to the US Cellular carrier. The hardware is literally identical.
Also consider that the V30+ is in the same boat. The US998 can be unlocked on the LG dev site (with a little trickery - you have to change the website code in Chrome for it to work)... but the US998U can NOT. We're not really sure why.
Presently... the LG Dev Supported Devices List does NOT list the US997U (G6+)... so I want to ask anyone here that says it can be unlocked how they did it. It's hard to find info on xda, since the "plus" version doesn't seem to have it's own portal.
Thanks, all!
I tried to unlock my US997U on the portal (selecting US997 from the dropdown) and my unlock was brutally denied.
Extremely lame that simply having more memory means I can't unlock my phone!
is there any update on this? can LGUS997U be unlocked? I too was denied on the LG developer website

YEAH SUPER LAME!. the website denied mine too. SOOO LAME. because fastboot gave me the CODE... SO LAME.
Unfortunately, your device( United States, (AMAZON(USA)), LGUS997U.AMZ )does not support unlocking the bootloader.
