Not sure about custom kernel part, but flashing H930DS to H930 does NOT lose dual SIM capability. Some people reported that in the beginning but they must have been mistaken, because like two dozen people after that said their H930 dual SIM functionality was just fine.

Also, even though you didn't specifically ask this, it's not necessary to flash H930DS to H930 to bootloader unlock and root. People had to do this a couple of months ago because not many H390DS Oreo KDZ had been released at that time, and we also thought H930DS didn't have fastboot flash commands. Later, we thought only some H930DS did. Now, we know probably all H930DS Oreo have fastboot flash commands. (Oreo is necessary for the bootloader unlock exploit.)
[LG V30 Guides, News, & Discussion] Stefanos71:
OK thanks for the information. I'm already bootloader unlocked and rooted. I updated my phone to the H930 EU ROM using TWRP.

I tried booting using the lunar kernel but got no radio. There is someone else on the lunar kernel thread who has exactly the same phone as me and their radio is working with the kernel. The only difference is that they followed the Frankenstein method to get to H930 EU so they have repartitioned. I guess I'll just try it and see.

Thanks for your help.

I don't know what I'm doing wrong here

I have a VS996 and want US998 but when I use normal LGUP there's no PARTITION DL option

and using the patched one gives me a "DLL for VS99620b is invalid" when I use uppercut.

What step am I missing here...?

I reinstalled drivers and tried a few different dlls without uppercut

EDIT: Found the random post with the patched dll and instructions on how to flash more properly

[LG V30 Guides, News, & Discussion] Mitsubisci:
I'm trying this method on a VS99620b. I have LGUP installed correctly (I think, I have the Partition DL option). When I try to flash the Nougat US998, LGUP goes through the motions and reports a successful flash, but doesn't prompt me to select partitions, the phone doesn't show anything is happening (progress bar remains at 0%). I did the master reset and LGUP refuses to flash the Oreo US998 onto what it thinks is VS96620b (which I agree with as I don't think the Nougat US998 flashed successfully.

I've reinstalled LGUP and LG drivers on two different PCs, using two different USB ports on each. Any ideas?

Edit: I just remembered that I checked the software version after this whole process, it was still VS99620b. So the flash is failing even though LGUP reports it was successful, if that helps at all.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yeah, I wrote up those instructions once we figured it all out, and there's a second post later in the thread where I did it with my 2nd LS996 converting to US998.

I'm not the creator of this thread so I can't put the Frankenstein instructions in post #1. BUT I have now edited post #5 (where I commented MONTHS ago) and linked to the finished instructions at the top of that post. Hopefully people will see it there on the FIRST page, even if not the first post. ;)

---------- Post added at 07:00 PM ---------- Previous post was at 06:58 PM ----------

There should be a pop screen to ask you to select partitions. Make sure it's not hidden behind some other window.

If you choose DL Partition method but don't choose any partitions, then it won't do anything. I ran into that the first time. ;) I had to find the hidden pop up window.
[LG V30 Guides, News, & Discussion] Mitsubisci:
When should I expect the pop screen to... pop I guess? I don't see anything at any time.

Also, the whole flashing process takes only a few seconds from start. Is this expected?

Also also, those are the instructions that I followed. The only difference I noticed is the LGUP directory contents. Yours had a lot more files in it than what I downloaded from that post (I only had the "model" folder and LGUP.exe)
[LG V30 Guides, News, & Discussion] ChazzMatt:
Takes at least a couple of minutes from start to finish. You will see the progress bar. I had time to take several pictures of the LGUP screen as well as my phone. I just used the better pictures, but I took at least half a dozen.

I had to move the LGUP window to see the other pop screen. It was hidden behind the LGUP.
[LG V30 Guides, News, & Discussion] Mitsubisci:
Just tried again, it skips the prompt alltogether, not stopping at the 4% Progress "USB Connection Established" step.

You need to have a full version of LGUP installed first. Then you copy the new lgup.exe and the folder over the existing install. That is why you are missing files.

I used a .msi file.

Install it, then overwrite lgup.exe with the file from the developer (patched) version. And copy that folder in as well.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Try this one then:

[LG V30 Guides, News, & Discussion] ChazzMatt:
Try a different computer? Turn off your antivirus? Then reinstall LGUP? Maybe it's preventing something from running or quarantining something.

I have Korean v300k with TWRP and root (KT carrier model with apps and korean text in settings). I live in Europe and would like to get rid of all the Korean text. Would it be possible to flash H930 ROM without the modem and recovery? I know that at least H930 runs on the phone (without signal) because that was used as a part of the bootloader unlocking process.

I took full backups with TWRP. If frankenstaining like this does not work, could I just use the backups to get to a state like nothing happened? Is the user data lost?

Also it seems v300L variant has the LTE B28 which v300k does not have. Could I try flashing only modem from v300L?

I want to be extra certain that I don't brick the phone.

[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes. See the WTF bootloader unlock, TWRP and root thread.

Since you're already on US998, you're already a step ahead, as it's one of the V30 models that has fastboot flash commands. You're also on Oreo, which has bootloader unlock exploit. ;)

That is the winning combination.

about to buy used LS998. i wanted to doubt check and make sure that if i do and convert it to US998, will it fully work without any issues on verizon.

my goal = lg v30 on verizon and having bootloader unlocked and root.

Thanks and sorry if this has been answered a hundred times. i saw that you can flash it to anything other than t-mobile, but wanted to make sure that everything will work (visual voice mail, also all cdma bands for verizon)
[LG V30 Guides, News, & Discussion] ChazzMatt:
CDMA definitely works, even on US998 firmware (since it's the official carrier unlocked model).

To get Verizon-specific features back, go over to these two threads and talk to the Verizon guys and girls. Some are just flashing back Verizon modem, others are flashing back entire firmware EXCEPT for TWRP custom recovery (so they keep root, etc.). They can tell you better since they are Verizon customers.

Just flashed my US998U+ to VS996 it's rooted, unlocked with no bootloader warning, wifi calling, VVM all functional. I do not see an increase in signal. Although I'm between towers in a small town if I go like 2-3 miles south of town I get 5 bars. In town no signal- 2 bars.

You can't use Uppercut with phone already on Oreo. Also Uppercut has nothing to do with this Frankenstein method. I do not mention Uppercut anywhere in the instructions.

You can't use regular LGUP for this DL PARTITION method Frankenstein. You need the dev patched LGUP.

-reflash modem US or VS

-airplane mode for a bit and turn it back off

For T-Mobile, all it took was the correct IMS settings in the hidden menu. I had it working on the H933 I have back in Canada with mt T-Mobile SIM. I ended up puttingbthe IMS settings back to Telus though when I got an S9+ to use on T-Mobile that also works with band 71.

[LG V30 Guides, News, & Discussion] ChazzMatt:
Well, this is the LG V30 forum -- and unlike the 2018 LG V35 (which, like the 2018 LG G7, is also a completely different device from the V30), the

G7 has their own XDA forum

, don't they? I'm just curious why G7 owners haven't discussed it among themselves? (Since I'm not interested in G7 I haven't looked over there.)

Whereas V35 owners can just post wherever they want, and their posts get "tabbed" as "V35" (so other V35 people can find then when searching) because there's not enough demand to have a dedicated V35 forum. They can post in G7 forum because it's similar internally to the G7, or they can post in V30 or even in V20 -- because it's a "V". ;) Dogs and cats living together, mass hysteria...

But I'll tell you two LG G7 variants you can't Frankenstein... AT&T and T-Mobile.

* AT&T G7 doesn't exist -- they're selling the V35 instead (which is a better phone than the G7 if only because it doesn't have a stupid notch).

* T-Mobile G7 probably has a different RSA encryption system than the other carrier variants, like the T-Mobile V30 H932 has different encryption keys than other North America V30 variants.

Who knows, all the G7 may have different RSA encryption -- in which case the V30 may be the last of its kind.

HELP!

Trying to flash LS998 to US998.

I did the first two steps. Just tried this and now phone is in an endless "no command error" loop.

1) Go into download mode (power off completely, then hold volume up button while plugging in USB cable)

2) open patched LGUP and flash

NOUGAT US998

to DL PARTITION. In the pop up box "Select All". Use the attached patched LGUP in this post.

I am trying a master reset but holding volume down and power buttons, letting go of power button and holding it again. The reset option appears but once I let go of the power button it disappears.

Interesting thing is, when it first boots up it shows V30+. When I let go of the power button it shows V30.

Glad you figured out the Master Reset. ;)

Yeah that post you quoted was from early May 2018, before we even had the WTF bootloader unlock and root directions written. Been a crazy couple of months since!

Back then Frankenstein was mostly used to just carrier unlock Sprint LS998 or flash "cheap" LS998 to something like the more expensive VS996 (So Verizon users wouldn't have to pay arm and leg to Verizon).

Now, of course it's a stepping stone to bootloader unlock and root, because flashing to US998 gives you the requisite fastboot flash commands.

Lastly, is the latest firmware build (US99820d_01_0710.kdz) safe to use for rooting?
[LG V30 Guides, News, & Discussion] ChazzMatt:
EDIT: MAY NOT BE SAFE!

For bootloader unlock purposes, use the US998 KDZ versions with no later than June 2018 security patch. Look at the names for dates in the title. You can always update to newer firmware later, AFTER bootloader is unlocked.
