[LG V30 Guides, News, & Discussion] ChazzMatt:
FRANKENSTEIN - CONVERTING ANY NORTH AMERICA V30/V30+ (except T-mobile H932) TO US998 OREO

I started this post off by explaining how I converted an LS998 V30+ Oreo to US998 Oreo. But this post has now changed into a guide on how to convert ANY North America V30/V30+ variant to US998 Oreo. EXCEPT, do NOT try this on T-mobile H932. You will brick your phone. It has different RSA encryption than other North American V30 variants.

SHORT VERSION:

1) Go into download mode (power off completely, then hold volume up button while plugging in USB cable)

2) THEN open patched LGUP and flash

NOUGAT US998

to DL PARTITION. In the pop up box "Select All". Use the attached patched LGUP in this post.

3) Master Reset. (

post 101

) (to stop the incessant bootlooping)

4) Flash

Oreo US998

in LGUP UPGRADE MODE. You can also choose REFURBISH MODE or Partition DL mode. (Make SURE you are choosing Oreo US998 and not accidentally re-flashing Nougat US998 again!)

Unless you are planning to unlock bootloader, go ahead and update to MOST RECENT KDZ in that US998 Oreo KDZ thread.

However, for bootloader unlock purposes, you will first use the US998 KDZ versions with pre-July 2018 security patch: 20a or 20b. You can then always update to newer US998 firmware later, AFTER bootloader is unlocked using the

WTF method

.

5) DONE.

NOTE: For Canadian H933 to convert to US998, [MENTION=5015107]cre4per[/MENTION] says you have to use DL Partition for both stages (Nougat and Oreo KDZ):

If you find you cannot flash Oreo in UPGRADE mode, then try DL Partition method again. If LGUP can't "see" the phone, go in make sure you have USB debugging enabled, and let Windows drivers install. Make sure you say yes for USB debugging for the particular computer you are using. Sometimes you have to revoke and re-enable the permissions.

READ THE INSTALLATION INSTRUCTIONS CAREFULLY. If you get a ".dll error" you either didn't install correctly or are using the wrong version of Dev Patched LGUP. Some people have used OTHER versions of LGUP before and ignore the installation instructions -- they think they know how to install and they do NOT --- then complain about .dll error, which is their fault.

HOW TO INSTALL DEV PATCHED LGUP

0. UNINSTALL any prior LGUP version. Seriously. Go to Programs folder and delete the LGUP folder if you must.

1. DOWNLOAD THIS DUAL VERSION OF DEV PATCHED LGUP, made by [MENTION=2651082]tecknight[/MENTION]:

https://androidfilehost.com/?fid=11410963190603845019

(Or use attached file from bottom of this post. Thanks to [MENTION=2651082]tecknight[/MENTION]! Please

go here and click the THANK BUTTON

!)

2. Extract LGUP_DualMode.zip to a folder on your PC.

3. Browse into the folder and launch LGUP_Store_Frame_Ver_1_14_3.msi.

Follow the prompts to complete the install.

4. In that folder, right click and select "Run as Administrator" on "SetDev.bat" to set LGUP to developer mode. < READ THAT AGAIN.

5. Launch LGUP using the desktop shortcut. NOT from folder icon!

As mentioned before, use UPGRADE, REFURBISH or PARTITION DL modes. REFURBISH and Partition DL are probably best.

WARNING: In LGUP do NOT go messing with modes not mentioned in these instructions. Especially do NOT use Chip Erase.

I don't care what anyone else tells you. If you listen to them, let them help you recover from messing up your phone.

It's all fairly easy. Most people breeze right through this. But if you have any problems, go through this list:

Make sure you in download mode BEFORE opening the patched LGUP file.

This is at the top of the list as some people forget to do that. The remainder are in no particular order. If that doesn't work,

Try different USB port,

Try different USB cable,

Try different computer.

Reinstall

LG mobile drivers on your PC.

Reinstall dev patched LGUP again.

Reboot the computer.

If you ask for help, that's the list of items we are going to give you anyway. ;)

What some people have is a problem getting LGUP to see the phone again AFTER Nougat US998 in order to then upgrade to Oreo US998:

________________

LONG VERSION:

Yes, but there's a middle stage of flashing to US998 Nougat. I tried to skip that stage, didn't work.

I now have mint condition Oreo US998 V30+ for $350, which started as LS998 V30+ off eBay.

OK, as the title says I converted the LG998 Oreo V30+ I bought off eBay to a US998 Oreo V30+. Did it tonight, and thanks to [MENTION=5550354]papoose515[/MENTION], it worked out fine. If I hadn't had his notes, I would have been stuck with bootlooping.

He's right. Here's what you have to do:

1) Go into download mode (power off completely, then hold volume up button while plugging in USB cable)

2) open patched LGUP and flash

NOUGAT US998

to DL PARTITION. In the pop up box "Select All". Use the attached patched LGUP in this post.

3) Master Reset (

post 101

)

4) Flash

Oreo US998

in LGUP UPGRADE MODE.

5) DONE.

That's the short version. Here's what really happened with me... (screenshots below)

First tried to go straight to US998 Oreo from LS998 Oreo, using DL Partition flash. (Not sure why in the screenshot below LGUP says it's Nougat LS998 "10a", it wasn't. It was Sprint Oreo LS998 in "About Phone".)

Anyway, didn't work. Oh, the US998 Oreo flashed, and the phone rebooted with ThinQ logo -- and I was feeling pretty good about the whole process.

But then kept rebooting over and over, even after a Master Reset. At first, wouldn't really boot, I kept seeing half second glimpses of the green Android on his back. Master reset (erase) and the phone started booting up, but would reboot again, over and over.

So, I did it all over again -- this time flashing US998 Oreo via DL partition over US998 Oreo. (Since I was already on Oreo US998 by this point.) Still didn't work to stabilize the phone.

Then tried "upgrade" from US998 Oreo to US998 Oreo -- hoping it would straighten things out. Nope, kept boot looping. It would sometimes get as far as letting me put in Wi-Fi password, before it started rebooting.

By this point LGUP was clearly recognizing the phone as "US998", while download mode kept seeing it as "LS998". (See screenshots below.) But wouldn't stay booted up for more than a minute, after flashing and after master reset.

Finally I did what [MENTION=5550354]papoose515[/MENTION] had done... I used LGUP to flash from US998 Oreo to NOUGAT US998 in DL Partition.

Yes, I downgraded to Nougat US998. STABLE. OK, upon Nougat boot up I did get a message my encryption was unsuccessful and to erase all data, but I didn't care. I wasn't staying at this stage long. Went in, confirmed in About Phone that it's US998 10D (Nougat).

I then re-opened LGUP and flashed Oreo US998 back as "UPGRADE". I went from Nougat US998 to Oreo US998. When it booted back up, it's now stable Oreo US998.

This was what [MENTION=5550354]papoose515[/MENTION] had done, but I tried to go straight from LS998 OREO TO US998 OREO. Using this LGUP method, you do need the middle Nougat flash, for some reason.

Anyway, I now have mint condition Oreo US998 V30+ for $350, which used to be LS998 V30+.

By the way, I used the Nougat dll patched LGUP for the entire process.

I also went into download mode manually for LGUP to see the phone. Otherwise it kept saying I had no phone connected.

At the end of the process you will have carrier unlocked US998 with these bands:

Every one who reports they used chip erase in this Frankenstein thread wiped their IMEI. It's not part of ANY instructions in this forum, so any one who does it in on their own.
