First, unplug the phone. You'll plug it back in after Master Reset.

Master Reset -- using buttons:

1. Press and hold the Power and Volume down buttons.

2. When the LG logo appears and quickly release the Power button only and press Power button again but keep pressing the Volume down button until you see the screen to select Yes to erase and reset everything.

Hi guys I apologise for the noob question in advance but would really appreciate some help.

I bought a H931 not knowing it cannot be updated unless you are in the States. Unfortunately, the phone that I received, the data is not working currently.

So I presume I need to update but am not quite sure how to do so. I am on the original Nougat Sept 2017 version for the H931. How should I go about turning this into a US998 exactly? Can I flash with the LG UP (I believe) mentioned here to US998 Oreo straight away? What are the precautions prior to doing this? I've done lots of flashing in the past but am not familiar with all these new devices with locked bootloaders etc.

Thank you!

Thank you very much for the replies. I really appreciate them although I found the answers myself.

I did not know the pop up comes after you initiate the flashing haha and did not want to start till I was 100% sure. I found out by watching Youtube videos to see where I was going wrong.

One last Q just to be 100% sure. Can you confirm that I can flash 20D from 20A without unlocking the bootloader please? And have you noticed any real improvements when updating from 20A to 20D?
[LG V30 Guides, News, & Discussion] nascar48:
Figured out my issue lol
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, you can downgrade 20D to 20A without unlocking bootloader. You can't unlock the bootloader on 20D as the July 2018 security update on 20D blocks the WTF bootloader unlock exploit.

Yes there's improvement flashing from 20A to 20D. Because 20B has a silent notifications fix. You could actually downgrade from 20D to 20B and get the same effect as going to 20A. It's also pre-July 2018, so you can downgrade to 20B and use WTF bootloader unlock exploit. Then you can flash back to newer firmware (if you wish) and still have unlocked bootloader. Or stay on 20B as long as you like.

So best buy has a really good deal on sprint variant v30s right now. I'm on Verizon. Obviously I can flash the sprint variant to be unlocked, but does anyone know if the resulting device will work on Verizon? I'm concerned that Verizon will somehow block the device based on the imei identifying the device as the sprint variant.
[LG V30 Guides, News, & Discussion] ChazzMatt:
You have to sign a contract with Sprint for that. It'll work on Verizon if you Frankenstein t US998 and have an already activated Verizon SIM card, but with the Best Buy contract, it's not worth it.

Whereas, you can get mint LS998 v30+ on eBay for $320. You can get already converted US998 v30+ on eBay for $295.

Mint

LS998 v30+ for around $300 on eBay

. LS998 converted to US998 won't have the AOSP incompatibility issue.

or buy

US998 V30+ already converted, for less than $300.

The only reason you would want to buy the slightly more expensive MINT LS998, is to ensure the AOSP compatibility, when converted to US998. This seller also sells already "converted" US998 (usually former LS998) but you have no assurance the original variant.

[MENTION=3250376]ChazzMatt[/MENTION]

Thanks for all your help in the Quark forum. I'm going to follow your lead and, sooner or later, switch to the v30.

Why do you need a converted ls998 for AOSP?

Is that true for all custom ROMS?

Thanks.
[LG V30 Guides, News, & Discussion] ChazzMatt:
You don't specifically need LS998, but you can't use AT&T H931 or Canadian H933 on AOSP ROMS right now , only on stock - based ROMs. Those are the two NOT to buy, if you want AOSP. The AOSP ROM devs are investigating, testing - - but who can predict when?

It's just LS998 V30+ (128GB) is the best value compared to VS996 (more expensive and only 64GB). You can convert it to US998 V30+ for bootloader unlock and root, then convert to bootloader unlocked and rooted VS996 V3O+ (which Verizon doesn't even offer!)

There's also AS998, US998 and those are also compatible with AOSP, but you have to make sure they're not former H931 or H933 which were converted - - when buying on eBay.

To confirm what ChazzMatt has stated, as a Verizon user myself, the phone will work on Verizon. If you have any signal problems, want Wi-Fi calling, or Verizon's version of Visual Voice Mail - you can flash the Verizon version of the firmware.

As far as the IMEI - it doesn't matter/they don't block it. If you really want to go through the process, they can add it to their database to make it "official". I did that through the online chat - it seems to take forever though. I told them it was an open market/carrier unlocked US998 that was previously used with Sprint, but no longer active on a Sprint account. There's a form they have to fill-out that includes needing to know the amount of storage (they may say memory, but they don't actually mean RAM), and apparently the color of the phone.

Hi guys,

I also made the mistake of using chiperase with lgup. And I discovered yesterday that my s/n, imei1 & imei2 are deleted....

The serial number doesn't matter to me or maybe in case of a warranty one day. I would especially like to find a way to give an imei for sim 2.

I created a topic yesterday: https://xdaforums.com/lg-v30/help/lg-v30ds-imei-repair-t3859288

I have already done the procedure for sim 1, but what I am missing is a correct qcm file from someone so that I can locate in hex the position at which I have to fill my second imei.

Could a charitable soul make this effort or show me another solution?

Thank you

J'ai moi aussi fait la bêtise d'utiliser chiperase avec lgup. Et j'ai découvert hier que mon s/n, imei1 & imei2 sont effacés...

Le numéro de série m'importe peu ou peut être en cas de garantie un jour. Je voudrais surtout trouver un moyen de remettre un imei pour la sim 2.

J'ai d'ailleurs créé un sujet hier : https://xdaforums.com/lg-v30/help/lg-v30ds-imei-repair-t3859288

J'ai déjà fait la procédure pour la sim 1, ce qu'il me faudrait, c'est un fichier qcm correct de quelqu'un afin que je puisse localiser en hex la position à laquelle je dois renseigner mon deuxième imei.

Est-ce qu'une âme charitable pourrait faire cet effort ou alors m'indiquer une autre solution ?

Try partition dl US998 Oreo. I've cross flashed to Verizon and back. Needed the master reset, and partition dl'ed. I've never used the upgrade option.

I know with one American MVNO (MetroPCS) person had to go "register" it with a store before the mobile connection would work. Yet with parent company T-mobile it works immediately and you don't have to do that.

I don't know what the rules are for Columbia.

If they search the IMEI it will show as LS998. Just tell them it's a mistake, you have US998. :)

[LG V30 Guides, News, & Discussion] ChazzMatt:
You can flash regional U.S. carriers' AS998, Verizon VS996, Canada H931, bedsides US998. All those are carrier unlocked models. But only US998 has fastboot flash commands, for those who wish to unlock the bootloader and root.

I've posted KDZ for all those models in the Development section.

Not sure why you would want to go back to Sprint LS998, considering you do not live in the U.S. It would be SIM card locked back to Sprint, a U.S. carrier. Only Sprint customers can actually use LS998. The ones I've bought off eBay I've immediately converted to US998. ;)

The only way you can convert back -- again not sure why you personally would want to, living outside the U.S. -- would be to root and flash the Sprint ROM someone put together. Sprint does not release KDZ, so you cannot update the phone if you are not a Sprint customer. They only release OTA updates to customers. You also cannot use the LS998 phone unless you are on Sprint network, since it's SIM card locked to Sprint.

From PM, posting with permission from user. I prefer to really post most everything help related in the threads so other people can also read.

US998 back to H932PR (which is NOT U.S. T-mobile H932SV)

Yes, if you can find a KZD for H932PR. Do not confuse it with the U.S. T-mobile H932SV. It's H932 for Puerto Rico.

Yes, they are a good source.

If you want to lock the bootloader back, you need to do it while you are still on US998 and have fastboot flash commands. If you flash back to H932PR, you will not be able to re-lock the bootloader.

When you flash back to H932PR you can TRY to go straight from Us998 Oreo to H932PR Oreo. You may have to do a Master Reset afterwards to stabilize.

The only reason we had to go to US998 Nougat first in Frankenstein is LG put in an extra check in Oreo to prevent that. So, we faked them out by going to Nougat, THEN to Oreo. You may get away with it going the other way, back to H932PR.

Sounds like you didn't fastboot lock the bootloader back. Also you have to use DL PARTITION mode to Frankenstein. You can only use upgrade if you are already on that variant firmware and full stock (no custom recovery

You are welcome!

UPDATE

Yeah, you just Frankensteined to H932PR, which is very much like all the other North American variants. It just doesn't have the fastboot flash commands of the US998... It apparently shares the same RSA encryption the other North American phones have, which is how whoever sold it to you was able to Frankenstein to H932PR in the first place -- before you Frankensteined to US998, and now back to H932PR. But according to IMEI, it started life as a SIM card-locked/carrier locked Sprint LS998 V30+.

Help! I have a bricked device, and I'm not sure what to do to fix it.

I followed ChazzMatt's steps, with the patched version of LGUP. I tried flashing US99810d_01_0411.kdz using Partition DL, and it got about 55% in (flashing the system), when it threw an error of 0x2000, Invalid command response code = 0x800000202. After some googling, this appears to be from an invalid version of the DLL. Turns out the version it's showing is LS99821a, which doesn't play nicely with Uppercut or any of the common DLLs I could find.

The problem is, since it was in the process of overwriting the system, it now only boots to download mode.

I couldn't find an LS998 version of a kdz to try flashing that in LGUP. I found a .zip of the LS99821a, but I haven't got TWRP on there (which is what I was trying to frankenstein it for), and LGUP's not allowing me to only flash the system.bin. I've tried hard resetting from recovery mode, but that didn't work either.

Any help would be greatly appreciated.

You need download mode to finish the process.

Unplug your phone.

Redownload both US998 KDZ you need. Maybe the Nougat is corrupted.

I couldn't read all of the comments on the thread (really bad internet *256kbps*) I have a US998 with the software version US99810b and I was wondering if I can just upgrade straight to the Oreo US998 update without going back to the nougat version?

I know it's a stupid question but it's my first time using a KDZ style updating because of the current internet speed I'm having :angel:
[LG V30 Guides, News, & Discussion] ChazzMatt:
If you are already on US998 Nougat, what is there to go back to? :p The Nougat US998 part is for OTHER variants trying to convert to US998. For almost all, you have to first flash US998 Nougat, do a Master Reset (to stabilize), then upgrade to US998 Oreo (20A or 20B, if you want to bootloader unlock and root).

If you already have US998 and are on Nougat, there's nothing for you to convert. All you need is to upgrade to Oreo US998 via LGUP.

If your goal is bootloader unlock and root, the temporarily go to US998 20A or 20B. Unlock bootloader, then update to latest US998 20E. If you don't care about that, then you can update now to 20E. See the US998 KDZ thread. They're all in there.
