Yes, there is. And what do the instructions say to do with that list?

You're on step #2. What does it say to do?

Furthermore what does the screenshots attached to the instructions show? But you don't even need the screenshots. Step #2 is plainly written.

There's 5 simple steps.

Do not freak out on step 3. ;) After step #2, your phone will be unstable -- regretfully necessary -- and then step 3 fixes that, so you can go to step #4. That's why the instructions are there.
[LG V30 Guides, News, & Discussion] Drive_It:
Where are these 5 steps? These are the steps I have read.

In step #3, Master Reset is not "factory reset". It's a different type reset -- perhaps a more powerful version of factory reset. So, read the link I provide in the instructions to know what it is.

Its on 20A and that person use a remote octobox to flash it. So my only options its get it flash with octobox or flash a custom ROM.....
[LG V30 Guides, News, & Discussion] ChazzMatt:
How are you going to flash a custom ROM? Is the AS998 bootloader unlocked, has TWRP installed and rooted? For all North America V30 variants -- except for T-mobile H932 -- you have to be on US998 firmware (at least temporarily) to unlock bootloader, install TWRP and root.

Unless you're telling me AS998 has fastboot flash commands? :confused: (We assume it doesn't, but if you have other information, please share it.)

All I can tell you is to try the Frankenstein instructions. But yeah, since Octopus Box was used to convert to AS998, it's very possible it can't be converted now to US998 via LGUP. If you find this to be the case, then get someone with Octopus box to convert/update to latest US998.

I was able to do it

Hi Chazz, I was able to frankestein the phone and unlock the bootloader.

I have done it like its mention in the tutorial but instead of using the V30 roms I used the V30+ roms( my V30 is the plus version). After I downgraded to nougat I got the flashing screen of "no command" and ,like its mention in one of the posts in this thread ,I made the master reset then it boot regularly. In the LGUP I got an error when I used "UPGRADE" option to upgrade to the pre-may oreo update rom and instead I select the "DL PARTITION" to upgrade and it upgrade with no issues. When I did this the LGUP recognized the phone as an AS998 instead of US998( in "about the phone" option it showed me that it was a US998) but still it let me upgrade the rom.

Then after that I had a hard time in the fastboot mode because the adb didnt find the phone when it was on fastboot and the reason it was the LG Drivers on Win 10 were the issue(I got the "ADB didnt ACK" error) and I had to use a laptop with Win 7 that I have and it let me unlock the bootloader. After that I update it the phone to latest version in the LGUP and the LGUP recognized the phone as "US998"

I purchased a V30+ on ebay... turns out it is a LS998 already franken flashed to US998 (had nougat on it) I used the LGUP flash procedure here and flashed the oreo 20a.

Flashed fine. My question is do I need to flash 20b, d , e etc.. in order to get to the latest version or can I just flash 20h?

I have not yet decided if I will unlock bootloader/root (if so, looks like I need to do that on 20a version)

[LG V30 Guides, News, & Discussion] ChazzMatt:
If you don't care about bootloader unlock and root, you can upgrade straight to US998 20H KDZ via LGUP. Just like you just did for 20a. You could have even skipped 20a and gone straight from Nougat to 20h.

Either use Upgrade mode or Refurbish mode.

If you ever do care about bootloader unlock and root, simply temporarily downgrade back to US998 20a or 20b via LGUP, and follow the WTF instructions.

I haven't actually tried it to downgrade to Nougat, but many have downgraded from V30 Pie KDZ to Oreo KDZ, so I trust it will also work for US998 Nougat. Better to have one Dev Patched LGUP than trying to juggle two.

I have a question about firmware version after Crossflash, im well sure i have V30+ US998 ( firmware work fine, 128gb), then i flash H933 Canada => i lost LTE network. So, i go back US998.

BUT, when i connect to LG brigde, it said H933 connected, go to update by LGBrigde it will download H933 lastest, but install fail.

SO, can you tell me what version off LG v30+ i had? or HOW TO FIX LTE net work when cross flash to H933.

Sorry my bad English.
[LG V30 Guides, News, & Discussion] ChazzMatt:
There are no 128GB H933 "V30+", except by Frankenstein. So your original V30+ was either

* native US998 or

* converted LS998 to US998 -- which you then bought.

You can use online IMEI database (there are many, like Swappa) to see what your V30+ phone originally was -- not that it matters. If it was LS998, you do NOT want that, unless you're a Sprint customer. It's why it was a US998 when you bought it.

Why do you want to cross flash to H933? In my opinion, US998 is better. It has fastboot flash commands if you ever want to unlock bootloader and root, while H933 does NOT.

Once you use Frankenstein to convert, you're not going to use LG Bridge to update.

Use LGUP, follow the directions. Go to US998 Nougat first, Master Reset, then US998 Oreo. Since you're coming from H933, you'll have to Partition DL at both stages, in addition to Master Reset.

If you want to try H933 again at some point in the future, make sure you go to H933 Nougat first, then Master Reset, then H933 Oreo.

Well, they are bolded, colored, underlined. :) In web browser, they are blue. Standard hyperlinks.

Your choice. You just need to go to Nougat. Most choose 10d.

Immediately after flashing US998 Nougat (Step 1), you will have temporary constant rebooting, which is fixed by the Master Reset (Step 2). Then you go to step 3 which is US998 Oreo. Make sure you read what Master Reset is (click the link in the Instructions)

For US998 Oreo, choose the most recent, which is 20h. Because your purpose right now is to try to fix your Wi-Fi problems.

Reference to classic novel "Moby ****". Something heard of but rarely seen.

A few H932PR have come through this V30 forum, and are almost always confused with the T-mobile H932. Possibly some owners even are confused themselves. But if you Google you see it is a completely different phone from the U.S. T-mobile H932.

Here's a site that lists many of the different models, including H932PR.

(Ignore that U.S. Cellular is listed as the the seller for US998. They were one of many retailers. The official carrier unlocked US998 was sold by 3rd party retailers like B&H Photo, and U.S. Cellular ALSO got the US998 only because they are too small a carrier to have a dedicated model.)

Back to H932PR... Not sure why LG gave it same model name (except for the PR part), unless the Puerto Rico carrier who sold it has some relationship to T-mobile or Deutsche Telekom (T-mobile parent company).

Initially people were interested in the H932PR, to see if it also had LTE band 71 (like the T-mobile H932) -- since H932PR was easily bootloader unlocked and rooted with WTF. (The T-mobile H932 could not be rooted until a few months after WTF was discovered, through a completely different method perfected by [MENTION=3167089]runningnak3d[/MENTION].) H932PR does not have LTE band 71 and no one knows why it shares model number with U.S. T-mobile H932.

Thanks for ur reply...and for the link sorry im using my phone so im didnt see that hehehe ....im not focus and currently im away from my PC .. and did someone ever tried flash from H932PR to H930K ? .its asia version.
[LG V30 Guides, News, & Discussion] ChazzMatt:
I don't recommend cross-flashing regions. North America variants can flash North American variants (except for T-mobile H932) and change those bands, change that firmware. It's like a chameleon. For instance, AT&T H931 or Sprint LS998 BECOMES US998 -- with those bands, fastboot flash commands, and that unbloated firmware. ;)

Whereas H930 variants (H930DS, H930D, H930G) cross flashing to other H930 variants does NOT change bands. H930DS can flash H930, but they still have H930DS bands.

This Frankenstein instructions is really just for North American variants. Sure, others can try it but it's on them, they take risk.

For instance, someone has written guide how to convert US998 to EU H930, and if someone wants to do that, they can -- but you have to omit the two modem files and another one -- and you still have US998 bands. :rolleyes: It's not completely converted to EU H930, the way Frankenstein works. The only thing it's good for is for people who need east European languages. And then every time you update, you have to remember to omit those three files, via Partition DL mode.

HOWEVER, when Korean carrier variants use WTF to bootloader unlock and root, they have to temporarily flash H930 firmware, but they lose all bands completely. THEN, after they get bootloader unlock and TWRP, they have to flash a special TWRP-flashable US998 zip to regain modem capabilities. It's not to convert to US998 -- but just to get their radio back. It's all listed in the WTF instructions.

Bottom line, I don't recommend cross flashing regions on V30.

[LG V30 Guides, News, & Discussion] ChazzMatt:
You keep saying that in several non-relevant thread..., but do you mean stock LG Pie or Linage-based custom ROM Pie? Stock firmware Pie is still being rolled out.

(I'm still on rooted Oreo firmware myself.)

If you want Lineage custom ROMs then you need to bootloader unlock and root, and flash custom ROMs. See WTF INSTRUCTIONS for that.

If you want just stock firmware Pie update, then convert to latest US998 Oreo and wait for US998 Pie. See Frankenstein instructions.

Or what I've done -- bootloader unlock, install TWRP, root, THEN update to latest Oreo US998.

What AS998 firmware are you on right now? Nougat, like 10d or early Oreo like 20a?

Yes, you can convert regional carrier AS998 to US988, using the Frankenstein instructions.

READ them carefully. Follow them carefully.

The only caveat is some AS998 were actually former LS998 converted by eBay dealers, using Octopus box to carrier unlock the Sprint LS998. In at least one instance, an AS998 user could NOT successfully Frankenstein to US998 -- due to something the Octopus box "broke".

When you talk about flashing firmware, does that essentially mean software? As in the operating system.

Yes.

Yes. As well as modems, bands.
[LG V30 Guides, News, & Discussion] Geforcefox:
Thank you for the response, I am trying to better understand the whole concept.

So the modem and bands are contained within the software, do they get flashed onto the phones internal storage drive, or to some type of chip?

If you root the flashed phone and instal a custom ROM, do you loose the modem and bands that you flashed?
[LG V30 Guides, News, & Discussion] ChazzMatt:
It's in the firmware. Firmware includes "software" but other stuff. Firmware is read only software that runs the hardware. Simplistic answer.

Custom ROM is more "software". This is why people have to update to CURRENT stock firmware before flashing custom ROMs or stuff isn't going to work right, like fingerprint sensor.

Flashing custom ROMs shouldn't make you lose modems or bands -- but often you have to create new APNs for different carriers.

Flashing LS998 to US998 also carrier unlocks that Sprint branded phone.

US998 has T-Mobile WiFi calling, etc.
