The only way I would do it is on a fresh temporary Windows user account installation on another computer. I bought a new Windows 10 desktop couple months ago, but have my prior Windows 7 PC as well as my wife's old Win10 desktop PC. (She currently uses a 17" laptop as her primary computer.)

I could wipe her old PC, just for something like this. Don't make the PC be seen by other devices on the network. I could then create a new sparse user account on the PC that would exist for only the duration of the session. It wouldn't have any personal information. Then that user account would be deleted, and even wipe the entire PC again. That PC hasn't been used for like 2 - 3 years.

Wouldn't something like that work?

Of course the $150 price (last time I checked), would be assumed to be part of the purchase price of the phone. ;)
[LG V30 Guides, News, & Discussion] ldeveraux:
Of course all of that would work, but that's not the point. XDA is the place where developers and end users come together to share ideas, complete tasks, and share successes. That initiative is thrown completely out the window when someone hides their technique solely to make money. Unless the method is available for free and this person is simply providing a service, it's the principle that matters most. Nuts to that!
[LG V30 Guides, News, & Discussion] ChazzMatt:
I think this is why XDA has removed links and you need PM or Telegram. Even the XDA News article that originally detailed it seems to have been edited somewhat.

I understand the free and do it yourself philosophy. That's why I've written so many guides. I don't charge for help. But a lot of people who do that have other full time jobs and this is a hobby. XDA and was built on sharing information, which I greatly appreciate!

The first people to try to monetize something like this was Sunshine Team with Verizon Droid Turbo. They said they had to invest lots of money and time into bricked hardware finding bootloader unlock and they needed to recoup costs. Any extra money would be used for future projects. They got a lot of pushback, but $25 wasn't much for freedom and tech support. To their credit, they kept the exploit up updated every time Verizon tried to block it.

Now in China, India, Thailand, Vietnam there are people for whom this is a living. So they don't want to offer it for free.

Also entirely possible this takes an expert to do and even people like me (advanced amateur) could mess it up?
[LG V30 Guides, News, & Discussion] ldeveraux:
I don't want to argue with you, but if most developers do this as a hobby and have full time jobs, they would be less inclined to require subsidy to develop tools. I understand if a person does this for a living (and gets results) would want to get paid, but not a hobbyist.

My impression is this is no more difficult to do than any of the earlier, more complex root/unlock techniques from a decade ago. They don't need access to the phone more than it being plugged in via USB apparently, no keystrokes or reboot procedures that they would need to manipulate the phone.

Ultimately after spending whatever it takes for the phone itself, I'm not trying to shell out $150 more to have it unlocked. I'll get a different device where that info is freely shared.

And I (we) greatly appreciate the work you put in. Before I get a new phone, I always check XDA for unlockability. I read your WTF thread where literally every model could be unlocked and that sold it for me!
[LG V30 Guides, News, & Discussion] ChazzMatt:
You are welcome!

And I have not bought the Galaxy S10+ yet, nor have I decided to use this service yet. I'm in another hemisphere right now, where my wife and I are adopting two children. Will be back in U.S. mid-December, and after that have much more important things we need to buy for our expanded family. I also need to go back to my job, where I will have been away for about two months, half of which is unpaid family leave. :(

I read explanatory comments by the author of this XDA News article. I'm not sure why he didn't just edit the article to add this information? :confused: But he mentions the $150 price is for newer phones, for older phones (Galaxy S10?) the price can go down under $100.

He also says Team Viewer is not always necessary (next to last comment), so I think something is generated that perhaps you then flash? He mentions a token is generated based on your specific phone's Device ID, using Samsung internal tools.

"Your device's ID and model are used to generate an unlock token. That token is then signed with a signature from Samsung. Special software (not ODIN) is then used to flash that token to your device's steady partition."

I'm not arguing about it either. Just interesting information. As I said I have too many other things going on in my life.

I rooted my US Samsung Galaxy Note 20 Ultra, and here’s what I’m doing with it

[LG V30 Guides, News, & Discussion] ChazzMatt:
* For U.S. S10/S10+ (Snapdragon) models, there's PAID bootloader unlock from someone who has access to Samsung internal tools.

* Also Hong Kong Galaxy S10/S10+ (which also uses Snapdragon) has FREE easy bootloader OEM unlock, but I don't trust using that international variant with U.S. carriers for VoLTE.

* Exynos chips (FREE easy bootloader unlock) run the rest in other parts of the world, but again VoLTE issues.

Yes, for U.S. S10/S10+ bootloader unlocked models you need TWRP/ROMs for Snapdragon variant, not Exynos. But there is

TWRP for S10+ Snapdragon variant

and there's at least

one Snapdragon ROM for S10+

(posted 11 days ago). I haven't checked for the smaller S10 (6.1", smaller battery). S10+ is 6.4" and 4100 mAH.

For me, I would probably do what I'm doing now -- TWRP, root and Magisk mods.

With Sony, as you mentioned, if you achieve bootloader unlock it blocks all proprietary features in audio and camera. That was such a frequent question with WTF exploit instructions, I had to specifically state near the top the LG V30 is NOT a Sony phone! :rolleyes:

Plus, yes, I do want Qi wireless charging.

Right. They grew up on texting, not actually WRITING/reading documentation. They want information spoon fed to them one step at a time. When I'm in the V30 Telegram thread, I've seen a lot of:

"How do I bootloader unlock my phone? Yes, I know there's the XDA WTF instructions, but I want you to copy and paste it here one or two sentences at a time while I'm doing it."

Like the cliched bomb defusing scene in action movies:

"Open the panel on the back with reverse hexagon screwdriver."

"It's open. Now what?"

"Cut the blue wire!"

"Cut. Now what?"

Also, they seem to be narcissistic enough they assume any phone problems they have are unique and could never had happened to anyone else! So, they don't need to go to XDA WTF thread and do a simple thread search, where a dozen people had the EXACT same problem and solved it!

And when you mention the Section 7 Trouble Shooting Tips, they say "What?"

Like you didn't read ANY of it, did you?

If I say, "Go to the V30 XDA ROMs section and look at the US998 KDZ Oreo thread", they say, "Can you give me a link?" A couple of times I

literally Googled it for them and posted the search results link.

There are many great people on Telegram, but when I help users it's mostly to point them to stuff I've already written HERE. I don't know why they don't start HERE first. :confused:

I have a strange problem. I flashed US99830b using LGUP Partition DL. My phone was stuck on the boot screen then, so after a lot of tweaking around in TWRP, which included trying to flash the TWRP flashable ROM of Pie. But it didnt work either. So I tried to return to Oreo US99820h but phone just wont boot to Download mode. I did Power up and plugged in USB, the four blue dots showed up, but then instead of entering download mode, the phone rebooted. Somehow reflashed US9980h through TWRP, but the phone still wont enter Download mode. It just reboots halfway through the process. Help please.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, lots of people have issues flashing to 30b Pie US998. See post #2 and post #6 at beginning of this thread for workarounds if you wish to try again.

But right now to get back Download mode... Go back into TWRP and flash US998 20e TWRP-flashable zip. You will re-gain Download mode. But then you need to flash 20f, 20g, 20h all back to back to get back to 20h with full functionality. The 20e, 20f, 20g, and 20h Oreo TWRP flashable zip files are incremental. You should not jump from earlier to latest. Go in steps. This started after 20d, since there were so many firmware changes.
[LG V30 Guides, News, & Discussion] TheDannemand:
Wet really should have a TWRP flashable US998 laf.zip for when people lose Download mode. We have one for H932 because it happens more often on that model, but it still happens on other models, as in this case.
[LG V30 Guides, News, & Discussion] Skyhawk1207:
Thank you so much for your help. But I can't seem to find US998 20e TWRP flashable anywhere. I'll continue looking, but I'd be very grateful if you could help me out with a link.

Does this ROM allow us to get VVM, VOLTE and Wifi Calling up and running on SPrint?
[LG V30 Guides, News, & Discussion] Skyhawk1207:
Are we expecting a US99830c update in the future or are we sure that's not coming? Asking cause I'd like to have Volte functions, but don't really wanna give up on US998
[LG V30 Guides, News, & Discussion] ldeveraux:
Who's your carrier?
[LG V30 Guides, News, & Discussion] TheDannemand:
I would not expect more updates, but of course it's possible, seeing some recent carrier model updates.

US998 has VoLTE and VoWiFi built in, but no user interface to show it or control it, except for TMO. You have to use Hidden menu (*#546368#*998#) - Field test - IMS Settings to control it. And it's far from user friendly.

I wrote some guidance on it in ChazzMatt's VoLTE thread and a few other places. I'll find some links once I get to a computer.

In many cases VoLTE will just work if your carrier provisions it. But you won't see any icons to show it, unless you specifically enable VoLTE indicator in that hidden menu. Again it's described in those earlier posts of mine.

Edit: Check the post linked below and the discussion from that point on:

[LG V30 Guides, News, & Discussion] Skyhawk1207:
Can't seem to get it to work still
[LG V30 Guides, News, & Discussion] TheDannemand:
I just saw that you are in India. That's why it doesn't work: Each carrier has dozens of configuration settings required to make VoLTE and VoWiFi work specifically for them. US998 has those configurations built-in for US carriers, and selects the appropriate one based on the SIM card. But it doesn't have the settings for overseas carriers. No US998 update would help you there.

If you knew all the settings, you could manually enter them in the hidden menu. If you have a rooted phone, I guess you could dig into the H930DS model (sold in India) and find your carrier configuration there and maybe copy it to your US998. There is a thread here specifically for that. Let me see if I can find it.

Edit: It's the thread linked below by @seadersn, one of our esteemed Dev's here. But it's for H930, which stores carrier configurations on the OP partition. US998 doesn't have an OP partition. So even if you can find your carrier's configuration on the H930DS (which presumably is structured like H930) it may not be possible to readily copy it to US998.

Keep in mind you have the dumpster fire variant of the V30!
[LG V30 Guides, News, & Discussion] Skyhawk1207:
The dumpster fire variant? What's that mean and how worried should I be?
[LG V30 Guides, News, & Discussion] TheDannemand:
So you have both a US998 and a H930?

This should definitely make your work easier.

Is it an H930 or H930DS? They are not the same. H930 is the European model (which I doubt has Indian carrier configs) while H930DS is the East Asian Dual-SIM model (which has them).

I THINK you can cross-flash H930 to H930DS, although I could be wrong. And I am pretty sure the modem wouldn't work if you do. Maybe because that pesky OP partition isn't part of the ROM. Please look around for confirmation before you do anything that might brick the phone or cause it to lose connectivity.

And you're welcome :)
[LG V30 Guides, News, & Discussion] Skyhawk1207:
Well it's the AT&T variant, which I got unlocked and then flashed to US99830b. So yeah its the H930. And thanks for the heads up! If I find it even a bit risky, I'll just say meh to Volte and make do with what I have.
[LG V30 Guides, News, & Discussion] TheDannemand:
That's not H930 (the European model) but H931 (AT&T model). They are very different. Even if you COULD convert your phone back to H931 (which you can't) it's not going to help you as H931 won't have carrier configs for Indian carriers.

Do you know anybody who has a H930DS?

In any case, study that thread I linked. Maybe H930DS owners shared information in there that you can use.

Would this work you have done be relevant to me and Sprint US?
[LG V30 Guides, News, & Discussion] TheDannemand:
I have no firsthand experience with V30 on Sprint, but I don't see why not, as the Sprint carrier config is built into US998. As long as the phone detects a Sprint SIM (or Sprint MVNO) it will try to load that config. Of course this assumes the Sprint (or the MVNO) provisions the phone and SIM for VoLTE/VoWiFi.
[LG V30 Guides, News, & Discussion] Skyhawk1207:

[LG V30 Guides, News, & Discussion] TheDannemand:
Understood.

You'll have to ask the Aix dev about that. It's a stock based ROM, and I assume it includes IMS.

As for it working on stock JohnFawkes 30a, I assume you mean the Sprint ROM -- which we'd expect to work on Sprint.

Since this is the US998 stock ROM thread, we should confine the discussion to that ;)

Hi, I tried to flash the US998 Pie zip stock rom on top of the US998 Oreo 20h and got stuck on the boot logo.

I tried 2 LGUP versions, the patched one from the Pie thread and an older one, Ithink it's the same 1.14.3 but without the dual mode. The PC has the correct drivers installed.

Anyone has some suggestions ?

HOW did you flash? TWRP? KDZ? Did you read the first post in this thread and the recovery info posted there?
[LG V30 Guides, News, & Discussion] Frankyxda:
Hi, thanks for your reply. I've managed to restore it to the stock Pie H933 ROM. I didn't realize that I was still able to access TWRP with the "button dance" because I was using modified stock zip that don't overwrite it, so I simply reflashed the stock ROM in TWRP and later in LGUP for Pie and that was fine. I don't have root anymore but I don't need it right now.
[LG V30 Guides, News, & Discussion] :
Hi, I flashed the US99810d Nougat KDZ using Partition DL, however instead of selecting all the partitions I left recovery in hopes of retaining TWRP. I inadvertently did the button dance right before the phone booted, out of habit (I was used to flashing H933) and now whenever I try to boot normally or into download mode, the phone boots TWRP and I have no idea how to get out of it.

Basically download mode is gone, however I can boot into fastboot, but doesn't seem to recognize my device even though I have the necessary drivers installed. I tried flashing JohnFawkes' US99820e, to no avail.

Any help would be greatly appreciated.

What happens when you boot into download mode via TWRP Reboot?
[LG V30 Guides, News, & Discussion] :
nvm, I manually booted to download mode and flashed US99820a. Turns out I wasn't holding the vol up button long enough.

However, fastboot doesn't recognize my device anymore, although ADB can. I've tried with different cable and devices, disabling signature verification on win10 in order to install Google's USB drivers, nothing seems to work.
[LG V30 Guides, News, & Discussion] TheDannemand:
Try installing LG's USB drivers, not Google's. And maybe another Partition DL to Nougat then back up to Oreo. All partitions this time.

BTW good job getting download mode back (y)
[LG V30 Guides, News, & Discussion] :
I've tried installing them both, no effect. I was actually missing a completely different set of drivers, which I found on a different thread. Fastboot works great after installing.

[LG V30 Guides, News, & Discussion] ChazzMatt:
You are probably thinking of Master Reset, to stop the bootlooping. But if you are downgrading from Pie US998 to Oreo US998, there shouldn't be any bootlooping. HOWEVER, if you are crossflashing from another firmware like AT&T H931, Canada H933, Sprint LS998 to US998 Oreo KDA -- yes there will be bootlooping. For those you will need to follow the

Frankenstein directions

, where you downgrade to US998 Nougat. Run Master Reset to stop the bootlooping. THEN, you can update to early Oreo US999 for bootloader unlock.

Hi all,

I have a quick question/issue which looks like no on else has using this rom. I have the US990 and ran stock Oreo for the longest time. I decided to update to pie so my work profile would be supported. At the about same time, I decided to switch to ting (using the T-Mobile towers). My current issue now is GPS is some what inaccurate. In Google maps, it sometimes is able to find my location but in actually using it for directions from current location to a destination, it says gpa is not available. I guess I'm trying to figure out is it is due to the pie update or if it is due to ting. I have the high acceracy setting enabled and all. If anyone has insight, be much appreciated (as my current thought process is either force flashing back down to Oreo (which I see may not be quite possible or smart) or try updating to 10...orrrrr try another budget carrier).

Edit, forgot to mentioni also tried Waze with still no gps.
