What carrier do you use? Just curious.

Last time I visited Brazil these were the LTE bands being used 2, 3, 5, 7.

But now on Wikipedia page I also see some Brazil carriers are using LTE band 1, 28, 38? (See screenshot. I'll get better one later.)

I'm sending a V30 to family member in Sao Paulo area, so curious which variant I should send. I was going to send US998 V30+, but also thinking about H939DS.

Also in Brazil some people use two carriers, right?
[LG V30 Guides, News, & Discussion] Nanderson1988:
I'm using the operator TIM, I changed my old Huawei P10 Plus on this V30 H932 but I had no problems with the LTE bands, we usually have more problems with bands of devices made here in Brazil than in imported devices.

The problem we face is the lack of Brazilian Portuguese language that does not have this variant.

Although I can handle Roms, Root, software had no idea that this H932 variant was as problematic as RSA encryption.

I thought it was possible to use a global rom, or no carrier link for this variant.

In relation to Brazilian LTE bands, here is still late for LTE, LTE + and 5G I think the US are far ahead and have more bands than here.

In this case the Variants in relation to LTE bands will not be the problem, unless ANATEL (Agency that governs the telecommunications profiles here) blocks IMEI (unlikely).

Please be aware of submitting a variant that supports our language.

I am using my V30 on PIE T-Mobile (Portuguese - Portugal) bands working perfectly.

Hi, i have my v30+ which has NOUGAT US99810d already installed, when i try to flash oreo 20a as upgrade LGUP says there is an error can not flash crooss platform it whos the phone as LS998. Any information on how to fix it?.... thanks.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Install the Dev Patched LGUP correctly.

Uninstall any prior version.

Also make sure you go into Download mode first, before opening Dev Patched LGUP.

A warning about the phone has failed to complete the boot process and will restart soon but never dose because I'm having issues with pie not working properly on my v30 I tried to flash US99830b_00_0902.kdz without system partition and H93030q_00_0902.kdz system partition only but it don't work......only doing this because GPS on clockwork widget does not work it for some reason tells the wrong time by 30 minutes and some people in my contact list are unable to ring me and vice versa but I can send messages but not receive them....

Any advice would be appreciated.

You are doing stuff not recommended in the Frankenstein instructions. Sorry, not going to help you cross flash any North American variant to any H930 variant. You are doing dangerous stuff.

Frankenstein is for North American variants only. It completely converts one phone to another, it's not for mix and match.

There's another guide someone else wrote about PARTIALLY cross flashing US998 and H930. You can go find that thread and ask there.

We've discussed this before:

Just did it and still getting the same error, I am checking upgrade in the LGUP am I doing this right or I need to check the Partition DL? Or do I have to flash Nougat (which is already installed US998) and then flash oreo as upgrade?
[LG V30 Guides, News, & Discussion] ChazzMatt:
For LS998 already on Nougat, going to Oreo you should be able to use Upgrade mode. But Partition DL is fine too.

Has anyone actually activated the Dual Sim on their north American v30 ??
[LG V30 Guides, News, & Discussion] ChazzMatt:
No North America variant has dual SIM card.

There's nothing to "activate". All North American variants have microSD card only.

In North America, we tend to use one carrier.

Is possible to do a crossflash from H932PR to H930?

So I own a V30 H932PR variant and I'm having troubles with my network provider so just wanted to know if I can flash another rom? Maybe the H930 and if it possible then how is it done? Waiting for a kind response, thanks
[LG V30 Guides, News, & Discussion] ChazzMatt:
You can flash it to almost any North American variant. Do NOT flash it to H930 or H930 variant.

Search the thread for "H932PR". You can flash it to US998.

H932PR (Not T-Mobile H932!) is a North American variant and can be cross flashed to other North American variant. You probably want US998.

See the

Frankenstein instructions.

I have what started out as a VS996. I unlocked it & installed TWRP per WTF and then Frankensteind the phone to a US998. It is now running US998-30B with no problems.

I would like to go back to VS996 to get VOLTE.

I have tried flashing the VS996 -30C zip through TWRP, but that does not work. It flashes but has some weirdness with some of my files)

My question is: can I simply use LGUP to flash the VS996-30c KDZ and do I use Refurbish or Partion DL.

Thanks
[LG V30 Guides, News, & Discussion] ChazzMatt:
So you want to give up TWRP and root?

If you do, Frankenstein back to VS996. Go to VS996 Nougat, then flash VS996 Pie KDZ.

Follow the Frankenstein instructions, but use VS996 instead of US998.
[LG V30 Guides, News, & Discussion] Lenster45:
I don't want to lose root and TWRP

I would rather wipe my current US998-30B and flash VS996-30C.zip

Which I did and it booted fine.

I panicked when I pressed restore in TWRP and could not see any of the backups I have made in the past

while it was still a US998. Is that normal for TWRP?

I guess my question is can I go from US998 -30B to VS996-30C.zip via TWRP

Thanks
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, most the Verizon users are on it. And at some point they flashed from a US998 firmware likely installed with TWRP flashable zip.

Go to this thread and read through the posts.

https://xdaforums.com/lg-v30/development/vs996-lg-v30-vs99630a000704arb00-kdz-t3952254

As for TWRP backups, depends on how much you have to wipe. Some people ended up having to use Refurbish mode on US998 30b, then re-install TWRP, then flash VS996 30c. While others are able to dirty flash from US998 to VS996.

Read the TWRP flashable instructions in post #2 of that thread, then go to the last page and read the final few posts.

I crossflashed my AS998 Oreo to US998 Pie

Here is how it went:

1. Flashed (PARTITION DL) NOUGAT US998 but after connecting to LGUP again it still showed AS998 and UPGRADE to Oreo US998 was not allowed.

2. Flashed (PARTITION DL) Oreo US998 and it worked.

3. Flashed (UPGRADE) Pie downloaded from here.
[LG V30 Guides, News, & Discussion] Lenster45:
Thank you.

Now on VS99630C and VOLTE is working

Turns out that the old US998 backups are now hidden from TWRP restore even though they are still present and you can see them through TWRP file manager.

[LG V30 Guides, News, & Discussion] ChazzMatt:
When you said you did everything, we assume you mean you followed the instructions... To verify that, you need to tell us exactly what you did, because I figure you skipped a step -- either not flashing Nougat first or not Master Reset.
[LG V30 Guides, News, & Discussion] blackbeard388:
ok first i partition dll to US99820f_00_1121 which is nougat than the no command logo showed up with bootloop than i master reset it than it went back to activating and it was restarting than i updated to US99820g_01_0110 which is oreo and it was still restarting than i partition dll the oreo and it was still the same problem
[LG V30 Guides, News, & Discussion] ChazzMatt:
So you flashed Oreo twice, and never used Nougat.

Why do you think US998 Oreo 20f is Nougat? 20f is one of the last Oreo KDZ releases. It's not even one of the early Oreo KDZ like 20a or 20b, which are used for bootloader unlock. The Frankenstein instructions even talk about Oreo 20a and 20b -- so there's no way that you could think "20f" is Nougat...

Instructions say to use Nougat and there is a link to Nougat KDZ in the instructions. Did you not even click on any of the links in the instructions?
[LG V30 Guides, News, & Discussion] ChazzMatt:
See screenshot.
[LG V30 Guides, News, & Discussion] blackbeard388:
on the lg fan club site said the 20f was nougat so what i have to do now if i download the 20a or 20f and partition dl it will it work ??

which nougat US998 should i use it
[LG V30 Guides, News, & Discussion] ChazzMatt:
No, they don't say US998 20f is Nougat. They know for V30 Nougat is "10" and Oreo is "20".

And even if they did (again, they do NOT), why would you not download from the Instructions links instead of some other website? While I often use LG-Firmwares (aka LG Fan Club) links as mirrors, for the Nougat download links all that is working is my own Android File Host mirror and LG Bridge Server URLs. On the Nougat KDZ thread I currently don't have any working LG-Firmwares links.

Read the directions, download from the directions. Click on the Nougat download link in the Instructions.
[LG V30 Guides, News, & Discussion] blackbeard388:
right now i am downloading 10c from your link if it finished downloading than i partition dl to this nougat and than i update it to the 20f or 20g or 20a or it is ok to use any of these

[LG V30 Guides, News, & Discussion] ChazzMatt:
Well first, update to latest 20h Oreo.

Use 20h KDZ just like you did to go from Nougat to Oreo. Use Upgrade mode.

___

Updating to US998 PIE right now is a problem. Go to the Pie US998 KDZ thread, and read the instructions. If it doesn't install for you, read the three workarounds. If those don't work for you, then you have to wait until another US998 Pie KDZ is released.

LG is supposed to update at least every 90 days. This first wonky US998 Pie KDZ came end of September. So possibly around Christmas? LG can always go sooner if they wish...

My daily rooted, bootloader unlocked V40+ phone is still on 20h Oreo. There's nothing different in Pie 30b that I need right now -- and I don't want to have to set up my phone again at this moment in time.

[MENTION=3250376]ChazzMatt[/MENTION] after flashing Android Q and finding out it doesn't boot I restored several TWRP backups of stock oreo only to find out that they all have lots of problems they didn't have before. Even a fresh install of stock oreo (ls998 30A) doesn't have a working camera, no youtube and other apps that worked before do not work any more. Do you think there's anyway to get it working maybe by starting the process from the beginning?
[LG V30 Guides, News, & Discussion] xaxxelous:
Mods closed the thread, but you can still get your bl unlocked. I just got my V40 done the other day. I rooted it and there is TWRP but it breaks exFat in stock Pie.

Not sure how much I'm im allowed to say here with all these new rules being cracked down on, but Telegram is really where you want to be these days.
[LG V30 Guides, News, & Discussion] ChazzMatt:
The LOS-17 ROMs require updating to stock Pie first or it won't boot. The LOS-17 ROMs have a few problems right now... They are a work in progress, and issues will be solved, but right now not many are using as daily driver:

If you DO update to stock Pie then that degrades your ability to run LOS-16 ROMs even when you downgrade back to stock Pie. You have to run permissive kernel for camera/flashlight and other stuff may not work. This warning is all in the

Root Sticky thread

.

I've heard those issues can also affect stock Oreo after trying to update to stock Pie and then downgrading back to Oreo...

Try this:

Partition DL to US998 Nougat 10d, Master Reset. See if camera comes back on that?

If so, then Partition DL to US998 20h. Your bootloader will remain unlocked. See if you still have camera?

On 20h, then use Section 6 of WTF to reinstall TWRP and root again. Then flash back to Sprint firmware.

____

There's a similar procedure involving Partition DL flashing to H933 Canada Nougat -- but I would only do that if you don't have camera on US998 Nougat. You would Partition DL from US998 Nougat to Canada H933 Nougat, with Master Reset. Then Partition back to US998 Nougat before going on to US998 20h.

Good luck!

Thanks. I'll do that Wednesday afternoon and report back.
[LG V30 Guides, News, & Discussion] ChazzMatt:
The problem is when the only solution for most people (who don't have the EU V40) to pay someone to bootloader unlock and root the phone via TeamViewer remote desktop software, development is not going to expand en masse. With any V30 variant, it can be done by anyone who can read Instructions. I know there are some people who want it done FOR them, but payment-only methods dependent on 3rd party actions inherently limit participation.

I participate in the V30 Telegram thread -- but I still prefer to answer support questions here. The V30 Telegram thread is mostly conversationalist and funny, but newbies who ask support questions are referred to documentation already written up here on XDA. They could/should have looked here first and gotten answers even faster. I'm not going to re-type everything again.

But there are some people who don't want to read, or who seek some other answer (which doesn't exist).

For instance, the problem updating to US998 30b Pie is well documented -- where people get stuck on the LG/ThinQ logo. It's discussed in

post #2

(#2!) of the US998 Pie KDZ thread and THREE workarounds are posted in

post #6

(still the first page) of that thread. It's also discussed throughout the US998 KDZ thread for 30b.

And the answer simply is if the

first method in post #2

doesn't work and the

three workarounds in post #6

don't work, then you have to wait for another US998 Pie KDZ. There's no other answer or else it would be POSTED in that US998 KDZ thread! ;)

Yet, people then open up NEW XDA Q&A threads to ask how they can update to US998 Pie KDZ (already answered in the US998 Pie KDZ thread!) and even go onto V30 Telegram thread to to ask how they can update to US998 Pie 30b KDZ. :rolleyes: All we do is refer them back to XDA V30 forum where the answers already are.

There's no answers on Telegram which aren't already here on XDA, at least for V30. XDA is where I go first, looking for answers. If it's not on XDA, I am very skeptical. For example, there's tons of fake V30 bootloader unlock and root instructions all over the internet! The only ones that work were created here on XDA. All the others are either blatant click-bait articles trying to get you to download malware or are hack copy-and-paste jobs that leave out important steps. A few (like on Reddit) are accurate but credit XDA for their content. They even post links to where they got the information, like the XDA WTF Instructions (which I wrote). The problem with that is the Reddit instructions (last time I checked) were not updated for the new steps needed for Pie -- while the WTF Instructions are current.
[LG V30 Guides, News, & Discussion] xaxxelous:
Yeah, I fully agree with you about the paying thing being limiting. For me, paying $10 and spending a few minutes on teamviewer was worth it. I'm not super into ROMs or other extensive dev these days. If I can have BL unlock, TWRP, and root on an unlocked LG then I'm pretty happy.

And, yes, I also agree with your stance on xda vs. Telegram. I was just trying to keep my response short. This is THE place for write-ups and finding answers first, thanks to people like you who put in tons of time here. Though I don't think the problem of people not reading everything available online about a phone before asking a question will ever go away completely ;) unfortunately.

When I referred him to Telegram I was really just meant if he wants to find out about getting a V40 unlocked and things of that nature.
[LG V30 Guides, News, & Discussion] cityneversleepz:
Thanks, I was just curious about the process.
[LG V30 Guides, News, & Discussion] cityneversleepz:
That worked perfecly [MENTION=3250376]ChazzMatt[/MENTION] ! Didn't need the canadian. Biggest problem was losing TWRP after flashing Sprint firmware. No idea why, but I needed to redo TWRP with ADB. Also don't know why but backups don't show up in the folder where they were when you look for them from RESTORE. I needed to move the backup I wanted to restore out of that folder with the file manager in TWRP in order to restore it. Once again you have the answers to fix almost every problem with the V30. That's another big reason why this phone is still the best root phone out there.

I am a H930DS HK user! Does this method really can use on my H930DS ? I can only see failed or got stucked when it running"fastboot flash unlock unlock.bin" as a result! I am using H930DS with 20n firmware! I have downgraded it from pie to oreo. Do I need any other firmware to get it done?
[LG V30 Guides, News, & Discussion] ChazzMatt:
This Frankenstein Guide is not for you. You don't need to convert to another model and you can NOT convert H939DS to North America variants anyway. You are in the wrong thread.

You want the WTF INSTRUCTIONS for bootloader unlock and root:

https://xdaforums.com/showpost.php?p=76584629&postcount=193

Those instructions tell you what Oreo firmware you need to be on and what to do. Do NOT read in an app, read on web browser. Best to print out and read several times!
[LG V30 Guides, News, & Discussion] ChazzMatt:
Very strange.

Have you ever been on stock Pie? If you have not, then you can use this older LGUP from this US998 Oreo Pie thread:

https://xdaforums.com/lg-v30/development/us998-lg-v30-us998-us99820a040330-kdz-t3786337

The installation instructions are different, with different .dll (doesn't work for Pie, but works for Oreo and Nougat).

See bottom of post #1 in that thread.

PRIOR CONVERSATION IN ANOTHER THREAD

With US998, you can Frankenstein (totally convert) to any other North American variant -- EXCEPT for T-mobile H932. Some people in other countries prefer to convert US998 to Canada H933. They claim it has a "stronger signal".

I don't know why that would be, and when converting to H933 you lose fastboot flash commands. Most people go the other way -- converting from H933, H931, AS998, LS998, VS996, H932PR (Puerto Rico, not T-mobile H932!) to US998, in order to obtain fastboot flash commands for bootloader unlock and/or to SIM card unlock their phone.

But to experiment, you can convert to Canada H933 Nougat. See if you have LTE signal.

One site says the H933

has both LTE band 3 AND LTE band 8.

H933

NETWORK	Technology

GSM / HSPA / LTE

2G bands	GSM 850 / 900 / 1800 / 1900

3G bands	HSDPA 850 / 1700(AWS) / 1900 / 2100

4G bands	LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 12(700), 13(700), 17(700), 20(800), 25(1900), 29(700), 30(2300), 66(1700/2100)

Speed	HSPA 42.2/5.76 Mbps, LTE-A (3CA) 750/150 Mbps

Read the

Frankenstein Instructions carefully.

Yes, they were written to convert to US998, but just reverse them.

* Flash to US998 Nougat via Partition DL (all partitions)

* Flash to H933 Nougat via Partition DL (all partitions)

* Master Reset (to stop bootlooping)

* See if you have LTE bands with your SIM card

* Flash to H933 Oreo via Partition DL (all partitions)

You HAVE to flash Nougat first. If you try to go straight to Oreo you cannot stop the bootlooping.

Also safer to downgrade back to US998 Nougat first before flashing to Canada H933 Nougat. Use Partition DL at all stages, choosing all partitions.
