Are there only two of three Korean variants which are unlocked yet? Can the F800S not be unlocked later?

Are you sure that the H990DS Korean variant can be unlocked in couple of month. If H900DS can be unlocked I will buy it in Germany now. But I must be sure that it can be unlocked later.

I'm NOT sure 100%
H990DS is NOT KOREAN
It's Taiwan Dual SIM & S_H_I_T

I advice you NEVER DO NOT buy :
H990DS ( DUAL SIM = F_U_C_K it )
BUY BELOW INTERNATIONAL MODEL NUMBER ONLY ( SINGLE SIM ) :
LG H990 V20 TD-LTE / H990TR

Ok I think you adviced me the Single SIM variant for better custom ROM community here in xda?
Then I will by a Single SIM variant where it's possible to go in fastboot and fastboot command work. I think H918 T-Mobile US version is the best for custom ROM community, right? Or are other Single SIM variants if rooted as good as the H918 variant?
Anyway I will not buy the Dual SIM variant.

Yes you damn right
Single SIM is for developers ONLY
If you can wait one or two month then,
1st and best option is :
International Single SIM :
LG H990 V20 TD-LTE / H990TR
If you can not wait , then
2nd option :
H918 T-Mobile US
both can be rooted in the near future
do as you wish
I must sleep now
The notion "wait a couple of months" is the most optimistic statement I've read on this topic. Dev's aren't big fans with LG and the ones who are, are typically working on the smaller market SINGLE sim phones like the T-mobile in the US. Root may never come along to the dual sim variant/s and that is just one of the reasons more of the "in the know" type phone users probably WON'T buy this phone. The dev community for LG dual is dead...yet I'm not sure why, this is where more of its USERS are.

Unfortunately I found this thread too late recommending against the dual sim H990DS.
I have one now and it's too late. I needed a dual sim phone as I carry a work phone and a personal phone and was tired or carrying two phone the whole time. I've had my eye on V20 for quite a while now and was excited to see it had all the specs I wanted including dual sim and MicroSD.
Does anyone think there will be a root for this device? I've always rooted my devices and for a number of reasons. Hearing that there may not be root for this model has made me reconsider my purchase.
Any idea guys?
Soon or Later LG will release unlock method for H990DS, I dont care about yet, lets Cyanogen mature on single sim V20s then move to dual Sim when Unlock is available.

Thank you for the quick reply AcostaJA. That is very reassuring.
Once I know there will be an unlock eventually I can live with that. I don't upgrade my devices very often so the idea of being stuck on stock for that duration was making me crazy.
I'm a fan of Cyanogenmod and look forward to their V20 release.
Thank you again!

Interesting list there. The F800K shipped with an unlockable bootloader like the H918?
"Dirty Santa"'s contributions are the F800L, H910, LS997 and VS995 currently. The other V20s are likely to be cracked open soon.

My my, you dislike dual-SIM phones so badly? Currently the H99DS has a AU$2015 (roughly US$1450) bounty, but there isn't yet an organized bounty for the H990 (though there are some disorganized folks who are offering). I imagine both will get broken in the same timeframe (not much more difficult to break both at the same time than just one).

They may in fact do that. So far Dirty Santa has only been applied to 4 devices, but most of what was done is pretty general and I imagine the rest of the V20 devices will follow soon. My fear is someone in LG management will say "Hmm, that merely encouraged them, don't be so lenient this time!" and they won't do so and be a PITA.

Did you ever figure out which variant will work in India? I've read that the Verizon one isn't sim locked, but do the GSM frequencies you need match?

They answer me that their model comes from Taiwan, so I presume it is H990DS.
Mine form eGlobal is on the way and probably at home on Monday.
I will let you know asap.

Currently, the two Dual Sim models are H990DS and H990N. The H990DS seems to mainly come from Taiwan. I got mines from Taiwan via eBay. I've contacted LG Mobile Singapore and their variant is also the H990DS. Perhaps there are more Asian countries that sell the same model?
Hong Kong seems to be the only one carrying the H990N.
According to this site, the H990DS and H990N are fairly similar in terms of LTE band support, with the H990N supporting 2 additional bands.

The big difference is the category of LTE.
H990DS is faster (cat.12) than H990N (cat.6) in upload/download.

The V10 dual sim (H962) did get root, but to my knowledge, the bootloader never got unlocked. It'll probably be the same situation for the V20.

Take a look at the message right above, on that thread notice this message.
The more interesting question at this point is bootloader unlock. Given how generalized the Dirty Santa technique is, I'm pretty sure unlocking the H990DS bootloader is merely a matter of a little bit of time.
The lack of a bootloader unlock for the H990 so far is the reason I haven't got one.
The US996 is missing three bands that are used where I live (band 1, 28 and 40). But if the bands can be unlocked I'd consider getting one.

H990TR ?
Kardeş uzun süredir takip ediyorum bir hareket göremedim TR yi gören cevap vermiyor zaten @ahmetoguz8
Guess it is past time to add a mention on this thread (in case anyone subscribed and didn't notice other threads). Took a while, but root is available for the H990. The major limitation is it requires a publicly known KDZ which is old enough to allow DirtyCOW to inject the unlocked bootloader. H990DS and H990N have been shown to work, though the root isn't 100% stable (there are miscellaneous reports of difficulties and the procedure is complex). This includes bootloader unlock, so you can do pretty much anything you want.
The oldest H990TR KDZ is January 10, which is a few weeks too late. Someone might try it, but I'd give poor odds of success. I'd give good odds if a 10a-10d was known, but no one has pointed towards one.

I have successfully rooted and everything works except voLTE. So i am trying to flash another Indian firmware via LGUP. So do i need to follow the "Going back to stock:" instruction from the rooting thread ? Or should just flash the firmware via LGUP ?
Copying my question from the n00b thread.
Hi Guys,
I recently got a H990 DS and I'm loving it. I was wondering if root is possible for it? The Android patch level states June 1, 2017 and the build is NRD90M.
Thanks!

And funny enough, you look at the source of the information and an answer is readily available. That build can't be dealt with, but for most H990 devices earlier KDZ files are available, so downgrading the image allows the root process to proceed. Afterwords getting back to a current image isn't yet a science, but is doable.
Does anyone know where I can buy this model? From what I understand, this single SIM version is the model that's likely to have the unlocked bootloader from LG and it was supposed to be released already.

H990TR is a Turkey Version ,

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?

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

Unfortunately, your device( United States, (AMAZON(USA)), LGUS997U.AMZ )does not support unlocking the bootloader.
