[LG V30 Guides, News, & Discussion] runningnak3d:
Have you guys checked to make sure that the RSA cert that was used to sign the US998 firmware is the same as the one used to sign the H932? (extract aboot from the US998 KDZ and compare the RSA signature to an aboot from an H932 KDZ).

On the V20, all the variants have the same RSA key to verify the firmware EXCEPT the H918 (T-Mobile). Good ol' T-Mobile decided to use their own key...

Just figured I would give you guys a heads up before someone bricked their phone.

I tried that with lgup and uppercut (trying to convert H921 into H932) and it goes to recovery and then it gives me an error saying something about cant convert models h931 to h932. Thats how far I've been. I got .dll from h932 and kdz as well.
[LG V30 Guides, News, & Discussion] runningnak3d:
FYI: If you guys can hold out for another day or two, I solved the last issue with the LAF protocol (talking directly to download mode). We can now flash whatever we want until LG updates lafd.

With an unlocked bootloader, it is just a matter of flashing TWRP, booting to recovery and flashing the su bin of your choice.

Unfortunately, I bricked my phone in the process (DUMB mistake), but to be safe, I want to test it before I release it.

DLL is in KDZ, will get the DLL from extracting aling with the DZ

I worked on H932 KDZ last night and got it extracted again, as I stated in earlier post I will work on it when I can on my day off Thursday, medical appointment came up on my 11yr in the morning on Thursday to see if we have to go thru surgery or be placed on meds, after that I will have a little time hopefully

Thinking of just repacking KDZ with H930 twrp.img and if it works we can flash sytemless or full system root zips which ever is preferred by the user
[LG V30 Guides, News, & Discussion] Josh McGrath:
I worked for a good while on the 932, and didn't see the need for the dll file. I'll post it tomorrow of I can, if someone doesn't beat me to it.

I'll also try flashing the 998 kdz tomorrow as well. I've been working soley on the 932, but this is all new to me and cant find anything out on repacking twrp over the stock recovery, but I have the files ready. Any tips, please let me know.

It's 445am. Bed time for me and I'll work on it more tomorrow

Sorry for late reply, didn't catch the message

My was out of the box on another software version, a few days later was asked to do an update, that is when I grabbed the stock H93210c KDZ off the server, was thinking of just incase moment due to not finding it anywhere

Also thank you for appreciating hard work being thrown in to this, the way I look at if tgere is a will there is way

[LG V30 Guides, News, & Discussion] brossovitch:
Going to try the whole process tomorrow when I get home. Couldn't today.

The problem currently, there's no TWRP for the 998 variant. Would the 930 version work? I have doubts..
[LG V30 Guides, News, & Discussion] Josh McGrath:
Usually twrp is the same across variants unless there are major changes like the SD vs exynos with Samsung

On the twrp page, it says if someone knows a way to flash it, then "go ahead" also.

That's where I'm at, I'm trying to figure out how to repack a kdz. But it seems you'll be done tomorrow before I figure it out I'm sure.

Although I am not familiar with the modifications to the files needed. Has anyone considered comparing the contents of the dll of the V20 UP file to the V30 up file to see if they can possibly spot what was modified in the original and potentially just copying and pasting that or something similar into the V30 file to try?

this is what I get with LGUP and my device in Download Mode. help?
[LG V30 Guides, News, & Discussion] TheDannemand:
What do the error messages say? What Windows version?

Depending on what the error is, some classic (potential) fixes are (A) running as Administrator or (B) enable Compatibility mode (on the executable's Properties tab) and select Win8 or Win7. You probably already tried those.

Also, the latest security updates from Microsoft (Meltdown and Spectre) have broken several programs that used to work before. Did you install those updates? If you have a PC without them, that may be worth trying.

the folder that it's looking for doesn't even exist. I'm at a loss.

we probably NEED to patch that DLL badly
[LG V30 Guides, News, & Discussion] runningnak3d:
Just curious, what is the goal of flashing the US998 KDZ?

If you extract the DLL from the H932 KDZ, I will patch it for you. Once you have a patched DLL, you will be able to flash the US998 KDZ via partition DL mode (a mode that is unlocked once the DLL is patched). But again, what is the end goal? The US998 still requires an unlock bin from LG, and they have a DB of IMEIs that are actual US998s.

/me is confused....

This is what happened when i tried to flash the h930 kdz just tells me that its not for the intended device. Gotta find a work around somehow
[LG V30 Guides, News, & Discussion] ChazzMatt:
You need to get flash commands from bootloader unlocked US998, if you can create a KDZ of such.

And then flash that US998 KDZ over H932.

Install TWRP, then use TWRP to flash back firmware for H932 -- and keeping TWRP custom recovery.

Yes the US998 has not been bootloader unlocked yet. But converting H932 to US998 right now would prove the concept works.

Uppercut works, but not for wrong variant kdz..
[LG V30 Guides, News, & Discussion] R800x_user:
I think our goal is to pretty much swap bootloaders since fastboot is disabled. So getting either h930 or us998 bootloader onto the h932 or gain root to be able to get twrp in it as well. Either one would help out.

Also as a side note thanks for you work on the v10 and v20.
[LG V30 Guides, News, & Discussion] TheDannemand:
Got it. So definitely an LG thing why it won't run, not a Windows thing. Move on, nothing to see here :o
[LG V30 Guides, News, & Discussion] runningnak3d:
Trust me, I get the concept :)

Has anyone checked to make sure the firmware was signed with the same RSA key? On the G5, G6, V10 and V20 T-Mobile used their own RSA key -- so I don't see why the V30 would be any different.

Just use hexdiff and compare xbl, aboot, hyp, tz, etc... from each model. It will be real obvious if they are signed with the same key. If not, then while LG UP will let you cross flash firmware with the patched DLL -- you will end up with the dreaded 9008 brick.

EDIT: also, you can't use uppercut AND the patched DLL since uppercut replaces the DLL -- so it is one or the other, and as you have found, uppercut doesn't fix it so you can cross flash.

You don't want to use the dev friendly LG V30 models to make ROMs? See post #2 and #4 -- but you already know that.

"Locked down also" like what? LG G6 has tons of dev work, because the carrier unlocked versions are not locked down.

[LG V30 Guides, News, & Discussion] UniX1rm:
The LG G6 T-mobile is still in the same limbo. You can technically unlock the bootloader but can't run fastboot. If it ain't official LG unlocked bootlaoder unlock method, it's not a real unlock.

Gotcha, well yeah, it doesn't compare to OnePlus though. (unless you're going for the cameras and dac). Waiting for the 5T and HTC. I am sure they might be a better value unless the pricing drop quickly, which I am sure it will in 3 months.

So the real question I have is this: How much of a chance do owners of the H932 have of ever getting root and flashing a ROM? I realize it's impossible to know for sure, but I ask the experts, what's your best guess?
[LG V30 Guides, News, & Discussion] jcsww:
Highly unlikely! With no way to flash TWRP due to the lack of fastboot commands, someone with a heck of a lot of knowledge would have to put in a lot of effort to figure something out, if it's even possible.
[LG V30 Guides, News, & Discussion] baillou2:
Good to know. I was foolish and didn't do enough research before I bought my LG V30. I was kind of pressed for time as my old phone broke. So now I have to figure out what to do.

The one good thing is that the default V30 experience isn't half bad, at least compared to all my past android phones where I HAD to have root access. I still want it, but I won't tear my hair out in the meantime.
[LG V30 Guides, News, & Discussion] jcsww:
I would like to be wrong but the carrier V20's seem to dictate the situation very well. Only the non-carrier and dual-SIM versions had the fastboot commands intact. The H932SV (T-Mobile version) is so far, the best version for band support based on actual owners reporting back with information from the field test menu.

Why do you need? I am still a big fan of root as well due to modifying the HOSTS file, debloating my devices, and to also flash custom ROM's on occasion. Custom ROM's aside. Debloating becomes a lot harder but most browsers come with ad blockers now on Android. It's not the perfect solution but it is better than wasting a third of your data on seeing garbage you don't want to see.
[LG V30 Guides, News, & Discussion] baillou2:
I guess the reasons I want root access are several. For one I just like to tinker. I admit it. But also there are ALWAYS things about the default ROM that annoy me. In the case of the V30 the big one is the volume limit when I plug in my headphones. It lowers it and I have to manually put it back up. It's one of those stupid things the hardware manufacturers do for god-knows-what reason. Also I can keep the phone up to date with the latest features. It just feels more "new" when all those devs port something over that the OEM will never do. And maybe I feel safer with root. I get the feeling that if something went horribly wrong with the phone my only option would be to do a factory reset and lose everything. It may not be true (is it?), but I just feel more at ease with a higher level of control. Plus it's a little bit of a principles things. I just hate not having control over the software.
[LG V30 Guides, News, & Discussion] jcsww:
I totally understand and agree with all of that! I wasn't aware of the volume thing but that is good to know. I don't normally use headphones with my phones because of the poor sound quality they put out. I am looking forward to using my Sennheiser headphones with the V30 though.

You can still do a factory reset through the bootloader but you wouldn't be able to reflash anything independently. The flash all command is apparently still there but it also verifies a signature. Because of that, you wouldn't be able to swap out the bootloader for one that is modified to allow the full list of fastboot commands or with one with the non-carrier US998 version. Sadly, the non-carrier version isn't even available until November 27th but the current list of band support, at least what is out there, states it has less than what has already been confirmed to be available on the H932SV and H933 models. That might be possible to change by flashing the radio from a different model or through a modded radio firmware but we honestly won't know until it comes it and after someone that has one starts seeing what can actually be done with it. The non-carrier US998 also needs to be added to LG's developer list before developers and owners can request that bootloader key to get more access to the device than what the carrier versions currently have and in the past, LG haven't exactly been quick about that.
