Error

I keep getting laf error mismatch is this normal, trying to flashback to nougat. Tried partition dl and upgrade/update mode. V30 plus "allegedly" was ls998, now us998. Using patched lgup to flash 998 Oreo or nougat brings back laf mismatch error, that being said fastboot and adb commands work but BL not unlocked.

I'm having some trouble with LG UP. I bought an already frankensteined LS998 it is converted to US998 on 10D. Now when I enter d/l mode and open LG UP it says im missing a dll for an LS99820D.

[LG V30 Guides, News, & Discussion] ChazzMatt:
Cricket is AT&T MVNO -- but owned by AT&T.

AT&T only gives updates over-the-air (OTA) for AT&T-branded H931 to AT&T customers on AT&T network signal. Theoretically you should be receiving updates, because you are a customer of an AT&T owned entity which uses AT&T network.... But maybe because you do not have AT&T account on the mothership, they are being mean and not letting.

Also, if you bought your phone "refurbished" off eBay, it's entirely possible your phone is not a true H931 -- but instead had a previous life as an LS998 or some other variant. Many dealers on eBay will "convert" variants to appeal to carrier customers -- they will advertise AT&T or Verizon branded phones, but the carrier firmware was flashed over an LS998 and they stuck an AT&T back cover on.

Anyway, if you can't get updates, then Frankenstein the phone to US998 and you can have the latest update whenever it's available. We post KDZ here in this forum.

Or you can bootloader unlock and root the phone and flash

THIS AT&T stock firmware ROM and have latest update

H931 now bootloops after Frankenstien attempt

Hi ChazzMatt,

First, thank you for your very detailed work on the LG V30.

I am not a total newbie as I have unlocked and rooted many HTC and Samsung products, however this was my first LG product and the H931 has its own set of differences from other V30's which I suppose created some confusion in my head.

So I am bootlooping endlessly at the initial screen, I can temporaily get the tiny donload mode screen to appear, but never get to the following screen. Also, the device does not "see" the USB connection anymore, no sounds or indications of a USB connection at all. I can do a master reset, but that is about it. I am waiting for the battery to die out watching the bot screen come and go endlessly.

I was flashing US998 kdz OREO to the DL partition with when this happened.

Any way to get back into LGUP or am I done...?

Your thoughts are appreciated.

Hammeru
[LG V30 Guides, News, & Discussion] ChazzMatt:
All I can suggest is to do Master Reset again...

You were flashing the US998 Oreo and this happened? Did it finish flashing?

Did you do Master Reset between Nougat and Oreo?

Make sure you know what Master Reset is... It's not factory reset.

H931 is no different from the other variants for this process. Every H931 person has done it.

[LG V30 Guides, News, & Discussion] customizedsolutions:
Hey ChazzMatt,

Thanks for all the awesome work you've done on this. I hate to ask for help, but I'm stumped.

Like lots of people on here, I bought a V30+ on ebay and figured I could update it from Nougat to Oreo.

My situation sounds very similar to TukcingFypo in post #487.

Well, now I'm stuck in fastboot, and nothing has worked so far to get me back into android.

Android told me that I had a US998, but the first time I flashed a kdz, LGUP asked me about the model, it thought it was a LS998. I did a "Chip Erase" flash, which might be my greatest error to this point. I'm not sure, I'm used to Nexus and Pixel devices.

So now I'm stuck. My boot screen says 30+Thinq, which it didn't previously say, so it looks like the flashes work, but just won't boot.

I've gone through the Frankenstein process several times, including the #101 resets between flashes. But I'm not getting into Android at all. It only boots to fastboot with options to restart or shutdown. And it won't respond to fastboot format commands because my bootloader is still locked.

Do you have any suggestions? This is a sweet phone, I want to get it back up and running again.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Chip erase will wipe out your IMEI. Search for chip erase in this thread, and you'll see.

Tell me exactly what you did, the steps to to that point. You flashed US998 Nougat? You must have also flashed US998 Oreo if you now see ThinQ logo.

Can you get into Download mode manually?
[LG V30 Guides, News, & Discussion] customizedsolutions:
Right, my first flash was a chip erase Oreo since it sounded like the phone was already Frankensteined. But that was clearly the wrong move.

Since it already seems hosed, I'm running another chip erase flash with US99810d_01_0411.KDZ to see if I can get the boot screen to say V30+ without ThinQ. That way I'll have some idea if the flashes are actually sticking.

When I do the post #101 resets, it only takes a couple seconds to complete. I would imagine it would take a lot longer. Then it's straight back to bootloader. Looks like SeeZaar (crossflash thread #73) successfully booted after chip erasing his phone, not sure if he got his IMEI back.

Yes, it does go into download mode without any problem when connecting the USB cable while holding vol +.

I'm downloading AS99820b_00_328.kdz right now. Sounds like some people had success with that.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, nowhere in my instructions do I mention chip erase as that's a very "destructive" command. Most people do not know nor care to regenerate their IMEI, and we sure aren't going to discuss changing IMEI. (forbidden topic)

So, just confirming -- you were already on US998 Nougat when you got the phone? I assume so, but I want to be clear. If you were, then any ThinQ logo meant you had US998 Oreo ostensibly installed.

If you can manually go into Download mode, what happens if you do that FIRST, then open the dev patched LGUP? It may not recognize the phone, due to the chip erase, but if it does, then yeah reflash Nougat US998, do a Master Reset and then flash Oreo US998.

Otherwise, you may have to google how to repair IMEI if LGUP doesn't recognize the phone.

Yes, Master Reset takes as long as a Factory Reset, it's not instant.
[LG V30 Guides, News, & Discussion] customizedsolutions:
Right, it was on Nougat when I got it, no ThinQ logo. In android, it showed as US998. I think LGUP even said that, but when I tried to upgrade LGUP didn't like something and said something about being a LS998. That's when I made the wrong choice about the flash option. Then, after that US99820a_04_0330.kdz chip erase flash I had the ThinQ logo, but a persistent bootloader.

The flash just finished and the boot screen says V30+, no ThinQ. Looks like I'm back to nougat, but still no OS. So that's something. I did the volume- power button, release power, power, reset, same quick response. Then it's back to bootloader.

LGUP now sees it as a US99810d in standby.

Unfortunately my hubris got the best of me. With my nexus and pixel phones I've erased, formatted and deleted partitions with impunity. Not thinking that LGUP could blank my IMEI settings. This is my first non-direct-from-google android phone since my HTC Evo V 4G 3D.
[LG V30 Guides, News, & Discussion] ChazzMatt:
If you look at my screenshots, at one point mine also showed LS998 in LGUP even though I was on US998 firmware.

Try "refurbish" mode to flash the Nougat US998 once again.
[LG V30 Guides, News, & Discussion] customizedsolutions:
I'm giving it a shot. I've tried lots of combos of flashing options and KDZs. My AS998 download should complete in a bit, I'll try that one too. I'm using the patched LGUP utility, it says DLL version 1.0.31.9

---------- Post added at 07:34 PM ---------- Previous post was at 06:40 PM ----------

Bummer, no dice on the US998 Nougat Refurbish. Still waiting on that AS998 download to complete. Slow going.

Holy crap, flashing AS998 using "DL Parition" worked. It gave an error about changing the partitions, which I approved of course, there is really only a couple degrees worse it could go.

I'm back in android, says it's a model number LG-AS998, Android 8.0.0. March Security Patch. No IMEI number though. That's the next challenge.

Thanks for the reply. I looked at that link and collected all the required software and patches. but when I run LGUP I get error stating "not support cross model download US998 to H933".

The thing I'm not understanding about the patches - they both include LGUP_common.dll, when I use the all variants dll, I get this error. "DLL for H93020d is invalid. Install vaild DLL package (*.msi) for the model". If both common.dll are to be used, then then they must be placed in different directories or renamed otherwise I'm just overwriting them. What am I doing wrong?

Please help.
[LG V30 Guides, News, & Discussion] ChazzMatt:
I would ask in that thread. I am not sure why they are not just using the Dev Patched LGUP only. The only reason you would install the "regular" version is so people can see where the elements go that you want to replace. But they probably have a valid reason for doing it.
[LG V30 Guides, News, & Discussion] Tinkerer_:
Thanks to all for putting this together and posting.

Only problem I encountered was installing the patched LGUP and DLL: Instructions say to create folders and copy patched LGUP and DLL to those folders, that did not work because a necessary DLL installed by regular LGUP was missing. Once I installed regular LGUP, then copied patched LGUP.exe and the new DLL/folder into the correct existing folders as instructed, it worked.

LG V30 H931 Replacement phone

Hello Moriatier,

I have a unique problem. I was using an LG v30 H931 (AT&T) for quite a while and then switched carriers to T-Mobile and ported the phone over to T-Mobile. Shortly afterwards the phone totally malfunctioned and LG kindly replaced it under their 2nd year promise program. The issue is, they sent a phone locked to AT&T and none of the companies involved will carrier unlock this phone for me. Quite frustrating....

LGUP is not recognizing the phone, but uppercut occasionally will. (Is there something different about the H931?)

My questions is, if I successfully get the phone flashed with a US998 or similar variant via Frankenstien, will the phone no longer be locked to AT&T so that I can use it on T-Mobile?

Thank you for any suggestions.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes. Flashed to US998 firmware, the former H931 will BE a SIM card unlocked/carrier unlocked US998.

Your problem isn't unique. Many people with AT&T H931 or Sprint LS998 have used Frankenstein to carrier unlock their phones, not only to use on other carriers but also to be able to update to newer firmware.

Here are the

Frankenstein instructions.

You will have these bands below when you convert:

http://www.lg.com/us/cell-phones/lg-US998-Unlocked-v30

US998

CDMA: 800 MHz CDMA

2G GSM: 850/900/1800/1900 MHz

3G UMTS (HSPA):850/900/1900/2100 MHz

4G LTE Bands: 1/2/3/4/5/7/12(17)/13/20/25/66

Additionally, with US998 you will also have fastboot flash commands if you ever want to unlock your bootloader and root. Bootloader unlock and root is not necessary to use the phone on other carriers or to update firmware, just informing you that on US998 you will have that option. You do NOT have that option on stock H931 firmware.

Do not use Uppercut on the V30. Uninstall it and never speak of it again. ;) Uppercut doesn't work on Oreo firmware on this phone (or Oreo on most LG phones) -- only Nougat. Plus, Uppercut can conflict with the Dev Patched LGUP you need to convert your North America V30/V30+ to another North American model -- in this case US998.

Instead use

Dev Patched LGUP, attached to these Frankenstein instructions.

1) All Verizon postpaid phones since 2012 (like 2017 LG V30, even 2014 Droid Turbo) are network unlocked. If you see that "warning" the non-Verizon SIM card should still work. It's a nag warning to smack you around for leaving Verizon. You apparently see it every time you reboot your phone.

2) Converting to US998 is still a good idea. You would use these Frankenstein directions. It's not as hard as you think and a little easier for Verizon VS996. Don't tell anyone I told you this (wink, wink), but for some reason for the Verizon V30 phones you don't have to flash Us998 Nougat first before flashing US998 Oreo. You can go straight from VS996 Oreo to US998 Oreo. I'm never going to put that in the instructions because ALL the other phones DO have to do that, and it will just confuse matters to list the one exception.

3) Sorry, I can't take money to do this work for you. I'm so busy with other stuff at my real job, I'm working 12 hour days, sometimes 6 days a a week. Barely get to see my wife.

I had a question about Pixel 2 XL. I know this is LG v30 forum, but hear me out as this might be the best place to ask it as LG is the ODM for pixel 2 XL.

There's a common problem with relocking the bootloader in pixel devices where the device gets hard bricked with recovery and system wiped out and only fastboot mode working. With a pixel, you can't flash any firmware ( even factory stock image) on a locked boatloader. So it's game over for a device in such situation. However, when I was playing around I found that the device boots up into download mode ( exactly the same screen as LG's download mode) when I press and hold the volume up button while the device is booting up. The device gets detected by my PC but not as a fastboot device or adb device. I installed LG mobile drivers and the device got recognized as an LG device. Then I downloaded the patched LGUP tool linked in this thread and it recognized my device ( so does LG flash tool). The problem is it always needs a tot or kdz file to work. I even tried a boot.img from Google factory images and I got an error reported on LGUP and my device .

So my question is, is there a way to flash Google's boot image using this tool by maybe putting it in kdz file format?!
[LG V30 Guides, News, & Discussion] ChazzMatt:
Interesting question. Someone like [MENTION=3167089]runningnak3d[/MENTION] would have more insight than me, as I'm not a dev.

Since this is Dev Patch LGUP it does have more permissions/options than "regular" LGUP. It also lets us crossflash to other variants we normally would not be allowed to do. So, theoretically yes, if seems if you created a Pixel 2 XL "KDZ" you possibly could flash it on your Pixel 2 XL -- but it would have to be correctly formatted as a KDZ or you would definitely brick your phone.

Again, I'm not a dev and [MENTION=3167089]runningnak3d[/MENTION] can probably tell you reasons this is not possible at all. I defer to him.
[LG V30 Guides, News, & Discussion] ASMstudent:
I know it's a long shot especially because the pixel partitioning is different from that of LG V30 ( No separate recovery partition). But with the device recognized in download mode I guess it means that it's a possibility that something can happen.
