Yeah, I'm still poking around in the aboot to see if anything else is different, but that's all so far. The reason that data would cause issues is because other parts of the firmware depend on it being set. At the very least, the "Invalid lg_model_name" error you were getting earlier would likely be caused by this. The 990DS bootloader (and rest of the firmware, like the modem and xbl partitions) uses "LG One Binary", where there's code for multiple models which is executed conditionally. I suspect this conditional execution is based on the values in that smem section. The dirtysanta bootloader doesn't have this code, probably because the firmware is specific to the US996 and just happens to work with other models with the same modem.

Would you be able to post (or PM me) some details about what exactly is still broken (ideally with a full boot log)? That would be helpful in figuring out where exactly to look. I don't want any part of the bounty, just want root working. :)

I'm not so much worried about bricking my phone (I know it's recoverable), but it's my main phone so I need the modem working for now.
[LG V20 Guides, News, & Discussion] emdroidle:
Key portions are here. The "modem subsystem failure reason:" comes from the function log_modem_sfr() in drivers/soc/qcom/pil-q6v5-mss.c. While the most likely source for the string "lge_init_fw.c" is one of the QSEECOM modules in /firmware (the "modem" area). Taking a second look, the "SMEM" area does seem suspicious.

Just upgraded from LG G5 H850 to LG V20 H990DS. I am in UK, disappointed to hear of no root on this device, but I am willing to pledge £10 GBP if we get it. I have never rooted the G5 but that was because I still had UK warranty. As my V20 is an import, I am open to rooting, but don't desperately need it. I just want the manufacturer to give us a choice!
[LG V20 Guides, News, & Discussion] theitgentleman:
I'd also be willing to pay for part of this test phone as long as you know for pretty certain he can get the job done

Thank you but there are no guarantees, although I have faith in his ability. eBay are listing them for £333 Look at this on eBay http://www.ebay.co.uk/itm/182329831426 which is still quite a lot of money to shell out for two of us.

If there is nobody on here who can lend us a phone a or sell one cheap, this an option. I'm happy to pay the £33 myself, can we raise £300 between the rest of us? We will post photos and updates throughout and hopefully get this thing rooted and maybe unlocked too. Once again, no guarantees at all.

Still waiting for the root and 7.1.2 nougat hehehe
[LG V20 Guides, News, & Discussion] rubiicon59:
You mentioned 7.1.2 so I thought the update may have been to 7.1.1. Which incidentally was released on 5 December 2016.

Pretty crap on LG's part that their flagship with the first release of Nougat 7 hasnt yet received 7.1.1.

Yeah most of us would like root but the possibility doesn't look good.
[LG V20 Guides, News, & Discussion] RdT21:
They will probably skip 7.1.1. Just as they skipped Feb and March security patches imho. Just my 2 cents.

Also 7.1.2 would not be deal breaker for me performance wise for the V20. It is already good as it is in my personal experience. I would not let it ruin my experience with the phone just because the update is late. I am more into security patches as it is more vital for our phone imho.
[LG V20 Guides, News, & Discussion] rubiicon59:
I'd like both security patch updates and firmware upgrades.

I'm only on a 1 March security patch because I upgraded with a slightly different firmware. Else I'd still be on 1 December 2016.

A few others with more experience than I have of LG have also said 7.1.1 will be skipped. Someone even thinks the next firmware will be straight on to O.....

[LG V20 Guides, News, & Discussion] rubiicon59:
How come? Have you got rid of your V, and if so what have you replaced it with?

Just curious.
[LG V20 Guides, News, & Discussion] jayfiled:
I swap out my phones quite regularly. It's a hobby. I want to try all the phones to find the 'perfect' phone. So I buy them when they come down in price, then sell my old one (usually months old) and think of the difference in price as the what it costs to 'hire' the phone.

So far I've realised the v20 (had pixel and galaxy s7edge previously) is my favourite because of the quad DAC and dual Cameras/SIM.

The only thing I don't like is the time it takes the camera to launch, quality of 2nd camera and lack of water resistance.

Sensible decision to grab the G6 seeing it has come down in price so early and improves on all of these.
[LG V20 Guides, News, & Discussion] rubiicon59:
Improves? Maybe you're gonna find it doesn't improve as much as you seem to think. Have you had a look through the G6 forum?

And I'd certainly prefer an accessible battery over water resistance. Do you think that will benefit you in the real world, in day-to-day use?

Had my Z2 just over 3 years and the fact it's also water resistant hasn't made one bit of difference, it's never come into play.

Edit: realised I've gone way o/t, apologies to the OP
[LG V20 Guides, News, & Discussion] carpler:
Today I see that LG included the G6 (european version) in the supported devices list with official unlock bootloader.

It's incredible: why this? why some device version yes and other no? For me it makes no sense!

No way to pressure LG?
[LG V20 Guides, News, & Discussion] rubiicon59:
Yeah we know it makes no obvious sense. But sadly that's the way it is.

There must be someone at LG reading these forums so it seems their attitude to most owners is "fk em".
[LG V20 Guides, News, & Discussion] emdroidle:
I find the current situation akin to playing Russian roulette, but with a revolver with 7 chambers and 6 rounds of ammunition. The situation is that frustrating. Worse, so far none of the devices with extra features that I want to play with (dual-SIM) have been unlocked. Placing a smart card into a SIM slot could allow for some interesting features...

Hrmm, I'd posted a message mentioning the situation yet that post has now disappeared. :( I was away from my desktop for just under 2 weeks, so minimal progress.

Just to help things along it seems SuperSU's update bootloop is not confined to the Sony Xperia devices. Luckily I suspect LGUP will be able to rescue my phone, but I am rather unhappy with this development and fixing this has to be my first priority.

The good news is when looking at a H990DS aboot image I found the string "ERROR: unable to write shared memory for sim_num". That is pretty much a smoking gun for the SMEM theory. This still requires a bunch of work to figure out how to modify the modem's shared memory, but does suggest this is very likely to succeed.
[LG V20 Guides, News, & Discussion] carpler:
I find the answer myself: LG will not listen or will never help its users!

[MENTION=6984210]emdroidle[/MENTION] is probably doing his best but it's no easy task.

I don't think his last post suggests "big progress" though.

If there's no way of root I'll be disappointed but not surprised.

If LG were more rational and included this variant in the bootloader unlock list the process would be infinitely easier.

It's the same sad state with the G6 too.
[LG V20 Guides, News, & Discussion] exadeci:
Root works and the phone is stable, the issue that emdroidle has, is that the sim(s) don't work, on most V20 there is only one sim so it was fairly simple to re-use what the first guy that rooted did, here he's trying to get the sims to work.

Jeez I'm way off base. Thanks for the link.

He's a lot further ahead with development than I realised.

I use my devices primarily as phones so a rooted non-phone would be pointless. As much as I'm missing root on my V it has to be fully functional.

I'd be happy if I could switch between a fully working phone without root, and having root for a while so I can run Titanium Backup Root and thus save and restore things and then un-root.

[LG V20 Guides, News, & Discussion] rubiicon59:
Typical.

We don't yet have A but already you're wanting B.
[LG V20 Guides, News, & Discussion] emdroidle:
Definitely not. In order to do something like that you need to be able to write to /system. Unless you've got a rooted device, dm-verity is checking for any modification of /system (even changing timestamps of files!), so attempting to disable those simply won't work.

There is a very limited ability along the lines you're thinking. It is possible to go into TWRP you can freely modify /data/data and change installed application files if you desire. This can be used to replace the Cookies file for Chrome with a symbolic link to /dev/null (Chrome will continue to accept cookies, but will forget them if the process exits).

Sorry for a OT question, but for me this things are closely related.

Suppose our dear emdroidle finally puts the root on the H990DS and suppose that in the future (I hope not too far) he (or someone else) can also bring the Lineage OS on the H990DS.

I've read that all custom roms for V20 american variants lack support on the second display.

The support on the second display will never be or there is a hope?

LG has a specific forum for developers that doesn't see a lot of activity.

There is a specific thread there for the V20 H990DS:

Subject : LG V20 990DS bootloader

Hello,

I am very keen to buy the excellent LG V20 990DS variant, but I will
not do so unless I can unlock the bootloader, as that prevents any
chance of experimentation with any kind of customisation.

I am a long time android developer and user, and I experiment with
custom roms on all my devices, especially on older ones once I upgrade
and I have less to lose.

There are many others like me.

Please, help boost sales of the V20 990DS, and release the tool to
unlock the bootloader!

thanks
Paul

I think the FM radio is broken when you root the other models. Since I use a bluetooth headset with existing phone, therefore there's no antenna for the FM radio, and I don't really miss it.
[LG V20 Guides, News, & Discussion] emdroidle:
I'll admit I haven't tested very far, confirmed phone connected to the cell network and confirmed I could receive data, but that covers the main issues. Should have tried receiving a phone call while I was at it, but being able to receive data is a very Good Sign.

Could simply use the cable from old broken headphones. Not a concern here, confirmed to receive FM radio signals.

At this time nothing (but this merely means features I don't use will be broken). I'm hopeful the HDMI functionality will be straightforward to fix, but it hasn't happened yet. Got enough of an HDMI signal that my display acknowledged it was receiving something, but my display had problems with the frequency being out of range. (thankfully nowadays most displays detect that and give messages, as opposed to olde days where it was possible to cause hardware damage)
