If I am reading this correctly, you stopped at US998 Nougat?

Update to US999 Oreo. Go to the most recent, which is US998 20H.

Use Upgrade mode in Dev Patched LGUP. If you still have issues, then flash US998 20h in Refurbish mode.

It also sounds like you have some kind of APN or carrier permission problem with cellular data.

See if flashing more current firmware like US998 20h helps that. Otherwise you need to contact your carrier.

Problem solved thanks to reply . i just factory reset phone and its work again , yes im using oreo US998 right now..and for wifi problem i have some clue. After im digging i realize my phone wifi ip is missing..what should i do ? I read some artcle its must flash modrm firmware manually . but how ?
[LG V30 Guides, News, & Discussion] ChazzMatt:
And you are on Oreo US998 20h? That's what I'm trying to confirm. Any less than that and you probably don't have the best firmware available. (20f in particular has lost of fixes and improvements.)

This was one reason I suggested refurbish mode in Dev Patched -- especially to 20h. Refurbish rebuilds your firmware. Alternatively you could use Partition DL and only choose the modem partitions from the 20h KDZ, but you should be on 20h first before doing that.

Yes im using US998 20h kdz right now and for wifi mising ip its since im using H932PR oreo firmware and US998 nougat...and im upgrade to US998 oreo the problem still present...i read some article its need to flash wifi modem manually and now im discover new problem..my phone cant extract any zip file...it alaways 0B file when im trying to extract it...and its need to write code manually :rolleyes. Any help i apreciate...thanks before
[LG V30 Guides, News, & Discussion] ChazzMatt:
What zip files are you trying to extract? Firmware files? What firmware files are zipped that you NEED to unzip before flashing? I don't understand.

If you're talking about anything zip related except firmware, please ask in another thread.

Have you used REFURBISH MODE yet to fix/refurbish 20h?

I'm still not clear how you got to 20h, and Refurbish mode will fix most issues by rebuilding your firmware.
[LG V30 Guides, News, & Discussion] anthidot:
Not firmware but any zip file like movie.music or anything ziped i cant exctract it..it always 0B size after i extract it...and i using same method to get US998 20h in frankestein intruction
[LG V30 Guides, News, & Discussion] ChazzMatt:
Ask me again after you use Refurbish in Dev Patched LGUP to reinstall US998 20h.

Let's focus on that instead of complaining about other stuff that doesn't work. ;)

Ok i will try it..thanks for help
[LG V30 Guides, News, & Discussion] ChazzMatt:
See post #88 and #73. Those people thought they bricked their phones but recovered. Don't give up hope. One had to do a "Master Reset" with power and volume buttons.

Master Reset -- using buttons:

1. Unplug phone and turn it OFF.

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

3. When the LG logo appears, quickly release the Power button only -- then immediately press Power button again, while STILL pressing the Volume down button until you see the screen to select Yes to erase and reset everything.

4. Release both buttons so you can make your choices.

I have an LG V30 H932PR on Nougat, from Claro Puerto Rico. Historically, updates on my provider have been glacial slow and was thinking about taking a chance and crossflash oreo from another device. I downloaded H933 Oreo KDZ from Canada (Rogers), but then I thought maybe I have a better chance of not bricking if I use another H932 firmware, maybe TMO?

Any ideas ?

In this thread, many people have had success flashing from Oreo Sprint to Oreo AS998.

The problem has been trying to flash from Oreo Sprint to Nougat US998. Maybe downgrade not possible and possibly other successful Sprint to US998 conversions (documented in other places, but in the past) were when both were still on Nougat?

But now as of yesterday we have

Oreo US998

. So, curious if that will work?

[LG V30 Guides, News, & Discussion] ChazzMatt:
But when you flashed to Oreo US998, you were coming from a converted Canadian H933 (formerly Sprint LS998). And you just used "upgrade"?

I'm curious if that option ("upgrade") would work to go straight from LS998 to US998 -- or if it (upgrade vs partition DL) only worked because you were already "converted" to a carrier unlocked model (H933).

Glad it worked for you! We just need to experiment more...
[LG V30 Guides, News, & Discussion] papoose515:
oh...when i first try to upgrade to Oreo US998 from the H933 it installed perfect the phone would boot up fine but as you got to the setup screen it would restart(boot loop) so then i flashed the US998 nougat then i used the upgrade option to upgrade to Oreo now it works perfect. Sorry for bad english.
[LG V30 Guides, News, & Discussion] Addiso:
Weird... I remember runningnak3d mentioned that the H930 and US998 has different RSA keys.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Interesting. I wouldn't have thought to re-flash Nougat US998 once I had already flashed Oreo -- and then you used "upgrade" to get back to Oreo US998. Congratulations!

Who said anything about the European H930? :confused: We're not discussing that. These are all North America variants.

We're discussing the Sprint LS998 which can be flashed to AS998 (regional US carriers), US998 (open market and U.S. Cellular) and H933 (Canada).

Of the three US998 is more popular, as it's more mainstream.

Also, an actual (from LG) US998 can also be flashed to VS966 (Verizon), but that's a different topic. Not sure if LS998 can be converted to VS966. Possibly it can, but no one in this thread has done it yet.

What variant were you flashing? i.e. LS998, H931?

How far had you gotten? Already done Nougat and were then flashing Oreo -- or were you flashing Nougat?

You try going into Download mode manually, or if that what you meant?

Read post #7.

Your phone is bricked due to bad flash from bad cable, moving phone while flashing, using PC while flashing, electric surge, or bad KDZ download (most likely).

[LG V30 Guides, News, & Discussion] ChazzMatt:
If you flashed to US998, your phone is now carrier unlocked and you have these bands:

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

What LTE band or bands does your carrier use? Some online research says Morocco carriers use LTE bands 3 and 20. If that's correct, then you have the right bands. However, if you were using LTE band 8, you wouldn't have LTE.

Also, contact your carrier make sure you are authorized to receive LTE bands. Sometimes it's a permissions issue.

[LG V30 Guides, News, & Discussion] neocyke:
You need to convert to another model. Despite what it says on the box in terms of bands, the us998 fw does not work everywhere. My local carrier here will only get picked up when running korean or EU fw. US fw sends me to wifi-only-land. Not VS not US. Never tried LS..

He's using LTE band 3, so he should have that. Both US998 and LS998 have LTE band 3.

I appreciate your help
[LG V30 Guides, News, & Discussion] neocyke:
On paper it's supposed to work. Yes. But in practice, there's something else in between. Same goes for my local carrier that uses LTE band 7. It's there on the list but it just doesn't work.

There's something that (possibly) disables the required bands to work on some carriers. In the states it may very well work but not outside. MCN? MNN? I dunno but there IS something.

Since you're in Morocco, I would probably suggest using EU Open.

[LG V30 Guides, News, & Discussion] ChazzMatt:
I never recommend partially converting to another variant. If he wants to do it, it's his phone. But Frankenstein is about fully converting.

Partially converting you have to leave off modem files and one other using Partition DL. And you always have to leave those off if you ever update.

I would recommend converting to Canada H933 to see if that works better.
[LG V30 Guides, News, & Discussion] neocyke:
Nope, definitely not a partial. It should be a complete model change unless it's a strict requirement for a particular fw. I tried this on mine before. Keeping US998 and then trying to flash korean modem. Since korean fw is structured completely different that didn't get anywhere. So, again, unless it's verified that different parts are needed, it's just a generally good idea to do a 1 to 1 conversion.

That said, a full conversion to EU H930 did get my phone working but signal reception wasn't as good as a korean fw. Hence my suggestion for Open EU.

Originally it was VS996 in case anyone is wondering. | VS996 - US998 - VS996 - V300 - H930 - V300 | with several other tries of those in between.
[LG V30 Guides, News, & Discussion] ChazzMatt:
You can NOT Frankenstein a US998 V30/V30+ to EU H930. You'll lose all telephone/data capability because the modems are incompatible.

There is no such thing as a full conversion for North American V30 to any H930 variant. You will lose modem. There are people who have workaround to omit modems and another file, but then they still have US998 bands. Then you have always omit those files when you update.

A full Frankenstein completely converts including all bands, because you are flashing all partitions. But it only works successfully on North American phones, and even then excluding T-mobile H932.

That's why someone wrote up the PARTIAL CONVERSION guide in another thread to let people PARTIALLY convert to EU H930 and keep modem capability and had EU H930 Pie. But that's a dangerous road to take.

If you are saying YOU converted your VS996 to EU H930 and it still has modem capability, then you have a magic phone! :) Because tons of people have tried, including the guy who discovered WTF bootloader unlock exploit. He actually bricked his phone and [MENTION=3167089]runningnak3d[/MENTION] helped him recover. He went from H931 to US998 to EU H930. Didn't work. Many others have tried also. Didn't work.

[LG V30 Guides, News, & Discussion] neocyke:
Well, that's just how it was. Mine is a china frankensteined V300 at arrival. I converted it to VS996 because that's what the imei turned up as just to see if I could keep it stock and english. Just ended up with a verizon dud. That's where all there various flashing experiments started. In the end it still had to be turned into a V300 to work.. still is.

For all I know the shop in china did something inside that makes it that way. You know what I'll try it all out again just to be sure when Ibget the time. Let you guys know later.

Oh btw, it was all done in oreo. Still is on oreo. Stopped messing with it after the screen broke.

Edit : forgot to mention, to the moroccan mate, you should consider rooting and flashing twrp zips instead of kdzs. Much safer and you have a safety net in case something doesn't work as it should..
[LG V30 Guides, News, & Discussion] ChazzMatt:
OK, I almost asked if you were using Octopus/Octoplus box or similar. They can do more extensive stuff than we can with Dev Patched LGUP (which is still plenty powerful).

One person in this forum had their phone repaired by someone with Octopus box and after that it was pretty much unbrickable.

So that's why you have a "magic" phone. The shop in China used something like that.

[LG V30 Guides, News, & Discussion] ChazzMatt:
On US998 firmware, for mobile signal type the icons are "4G" (which is really HSPA) and "4G LTE" (which is REALLY LTE). Stupid American carriers.

The small LTE part is very hard to see. See attached screenshot, from my original stock setup before I modified it to make sense.

Hello ChazzMatt,

In US998 when i turned data on i see 4G/LTE Icon

but unable to connect.

And in The Canadian version there is no icons even if turned data on ...
[LG V30 Guides, News, & Discussion] ChazzMatt:
If you see signal but are unable to connect, it's probably either APN problem or carrier permissions problem.

You may have to edit your APN to match the carrier's settings.

For permissions to connect to network, sometimes it's something the carrier needs to allow on their end. They see a strange device and need to say OK. If that, you will need to contact them.
[LG V30 Guides, News, & Discussion] HoussineOulhaj:
- I'm sure APN Settings are coreect becuase i copied my worked one

- Ok i'll go back to US998 and try contacting my carrier

In case anyone else runs into this issue...

I was on H931 (ATT) and before you can flash Oreo you need to boot up the phone so it is recognized at US998. If not, you will get the cross flash message because it will still see it at H931 in download mode.
[LG V30 Guides, News, & Discussion] christopherrrg:
Hi [MENTION=6852175]HoussineOulhaj[/MENTION], if you want functioning 4G/LTE on H933 you'll need to start out by doing a device dump on stock h933 kdz, then with some of those files you'll direct flash with DD and ADB. After all of your conversion.

[LG V30 Guides, News, & Discussion] ChazzMatt:
Depends on what you mean by undo it.

Not to pure stock AT&T, as AT&T doesn't release public KDZ. This is why non-AT&T people have to use Frankenstein to convert to another North American variant to carrier unlock it and receive updates with publicly available KDZ.

For people who are AT&T customers, they have to temporarily convert H931 to US998 for bootloader unlock and root. Then they can flash back to AT&T H931 firmware via TWRP-flashable zip (ROM) made by devs. So, you are back on AT&T H931 firmware -- but have TWRP custom recovery and root.

Tell us why you want to undo it and we can give better answer.

What was your reason to Frankenstein?
[LG V30 Guides, News, & Discussion] stinka318:
Can anyone tell me if you can flash h930 kdz on a us998 64gb phone thanks in advance........
[LG V30 Guides, News, & Discussion] ChazzMatt:
I wouldn't do it. Why do you want to do it? What does H930 firmware have that you think you need? You already have fastboot flash commands and these radio bands:

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

If you did flash it -- unlike with the North American variants which cross flash completely and BECOME the new model -- you with H930/H030DS, etc you can't change radio bands. In fact you would lose your radio (telephone capability) as the H930 & US998 modems are not compatible.

There is a guide someone wrote to cross flash H930 with US998, but you have to omit the radio modems and another partition. I don't recommend it as I see no gain in doing that. And every time you update via KDZ you have to remember to always omit those three partitions.

And please don't say your question has something to do with custom ROMs. :rolleyes: If you say that, that means you really don't know anything about these phones have not even read the ROOT STICKY. Read post #2 for advice custom ROMs and how ALL V30 can run custom ROMs.

https://xdaforums.com/lg-v30/how-to/root-v30-t3927154

If your question has nothing to do with custom ROMs, sorry. It's just others see "H930" name attached to all the custom ROMs which does NOT mean they are only for H930. They are for all V30. It's just the first ROM developer -- who is still active -- had an H930 and the naming structure reflected that. The ROMs are compatible with all V30.
