The alternative to going into Download mode before opening LGUP is to let LGUP boot the phone to Download mode when executing the Start command. But doing it that way often gives error message that no device is connected.

Try downloading the Dev Patched LGUP from the US998 KDZ thread. Should be the same, but it's a different copy. For some reason that worked for a couple of people. Don't know why.

Also temporarily turn off your antivirus, when downloading and patching. That could be interfering.
[LG V30 Guides, News, & Discussion] Bob Simons:
somehow, no joy

I just stared from scratch on yet a 4th PC after finding there is no LGUP for the mac. I installed the LGUP, the patch containing the EXE and the DLL, and then the drivers file, then plugged in then phone and waited for it to install all the drivers and then started LGUP ad it did the same thing, refused to cross flash at 4%. now, do I need to set the phone in any particular way, developer options, USB debugging etc or does none of this matter when in download mode?

I'm going out of my mind here. I've done everything on your list dozens of times now, or at least think I have. meanwhile the phone under "about" says its a us998 but lgup insists its an h931.

So now what do I do? the phone is now in a bad way. on 7.1.2 on US998,

also, I disabled antivirus, installed as admin when I could (can't easily when installing an MSI), and again used lots of good cables and ports.
[LG V30 Guides, News, & Discussion] ChazzMatt:
So, you did successfully convert to Nougat US998? I thought you had NO success yet.

Did you do the Master Reset?

Yes, after that go into Developer options and turn those on. Sure agree to ADB and all that. May not be necessary but doesn't hurt.

You'll also possibly need to close LGUP and start a new session. Put the phone into Download mode manually.

i thought i said i got ino nougat but no further

I'm sure I said that I did the master reset twice because it wouldn't stop restarting. I've been restarting LGUP endlessly.

Will it be obvious how to put the phone manually in restart mode? This is a special restart command so it comes back up in download mode? I'll try to look it up

edit"

that did it. should've done that a few days ago, or so it seems.

as soon as I finish installing, do I then run magisk? it rebooted after installing 20a. so it;s now time to switch to wtf?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Has it stopped bootlooping? You did Master Reset twice, are your stable now?

If not, you can Master Reset without completely turning phone off.

If so, then go in and do rudimentary phone set-up. You don't have to sign in, but enable Developer Options, ADB.

Hi Brother

Hello friends, I was able to install Android Oreo to my LG H931, what I did was install the Oreo US998 android and once installed, restore to factory mode and I had perfect Oreo android without any problem.
[LG V30 Guides, News, & Discussion] Bob Simons:
did I just make a terrible mistake?

I made it all the way through the setup and then installed the H931 rom and seem to have lost root and trwrp. how far back do I need to go? yes, the twrp backup failed twice so I have nothing. Can anything be done or no? if so., where do I go back to?
[LG V30 Guides, News, & Discussion] ChazzMatt:
After installing the H931 ROM you have to flash Magisk before rebooting. Otherwise you will lose root.

You can try to boot to TWRP via the hardware button dance, but it's not easy.

If you can't do that, you can use LGUP to flash back to US998 Nougat to get fastboot flash commands. You don't need 20a or 20b, as your Bootloader is already unlocked. But since you have them downloaded already, you can use those.

Once you get fastboot flash commands back, then reinstall TWRP and flash the other two files.

i started over and just booted into TWRP but dont have root

it appears I cant get Majisk on this thing.. I search for it and itr doesn't appear. I try to install it and nothing happens. can you advise me on what Majisk I need?

I used LGUP to go back to nougat and then to Oreo, and while in Oreo I follow the instructions for the twrp, Majisk, and the two decrypt or similar apps. thinking it was OK I booted to system and then searched for a root reboot app and it failed because I didnt have root. I searched for Majisk and found nothing.

I also tried to flash the AT&T you told me about and I found I had no root and it seemed the rom overwrote the recovery but I dont know that or if I only lost the y to get to twrp. I was able to get in with the buttons and the power cord

So is there a "security program removing Majisk fro the google play app list? is it actually removing the program or just the appearance of it?? Do I need to download it using a PC going to the play store/?

What do I do? I thought I was doing well and I lost several hours again.
[LG V30 Guides, News, & Discussion] ChazzMatt:
You flash the Magisk zip in TWRP. That's what gives you root. You also need to install the Magisk Manager app/apk then in the Oreo OS after you reboot. The Magisk Manager lets you give root privileges to other apps like Reboot Recovery, Titanium Backup, etc. Or hide root status for apps like Google Pay.

Use Magisk attached to the WTF thread.

You will probably need to put all those files on your SD card, as the H931 ROM auto wipes the internal memory during installation. I distinctly remember telling you that in a private message and quoting the thread instructions.

Read the H931 ROM instructions carefully. I've never installed it myself.

ChazzMatt, your a big help around here. There’s no video tutorial for this?
[LG V30 Guides, News, & Discussion] ChazzMatt:
You're welcome.

By the way, if you notice, Bob finished Frankenstein successfully. And he even finished WTF successfully. No video needed. ;)

When I had to go to bed last night,

* He had converted AT&T H931 to carrier unlocked US998 Oreo -- which is Frankenstein.

* He had also unlocked his bootloader, installed TWRP and rooted. That's WTF.

What he was stuck on then was flashing the latest AT&T H931 TWRP-FLASHABLE zip and getting it rooted, to get AT&T firmware back on his phone while keeping TWRP and root.

That's really not in the bounds of Frankenstein instructions thread nor WTF instructions (although the TWRP flashable zips are mentioned at the bottom of the WTF instructions post).

Yet, we were still in this Frankenstein thread discussing ALL that. It confuses people. They think they need to unlock bootloader to convert to another variant or to carrier unlock their phone. No, you don't. I really try to keep bootloader unlock discussions in WTF thread. While Frankenstein is used by most North American variants during WTF, it existed before WTF and has its own separate purposes.
[LG V30 Guides, News, & Discussion] cityneversleepz:
How many times have you told someone PRINT OUT THE INSTRUCTIONS. How many of the people that have multiple problems listened? IDK, but I'm betting not many. If they would print and read the instructions more than once, the second time with a high lighter, I think most would have much less problems.

Without his nudging, these instructions for Frankenstein probably wouldn't exist. "Frankenstein" for V30 predates WTF bootloader unlock and is used to carrier unlock or convert to other North American V30 variants. Later with WTF, it also become crucial for non-US998 North American phones for bootloader unlock and root (except for T-mobile H932).

I am on vs996 oreo version vs99620j.

Should I use the same kdz that were mention on the message i quoted before or should i use another ones?

And in the case i brick the phone can i unbrick it?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Tell me what the directions say to flash? ;) It's fairly clearly written. I really want you to read the directions...

Nobody has bricked their phone doing actually following the instructions -- except U.S. T-Mobile H932 users who ignore the warnings not to do this on U.S. T-Mobile H932.

Like take a look at this:

He did NOT brick his phone. He just stopped after step #2. Once he actually followed the instructions (steps #3, #4, #5) everything was fine. ;)

And there was ANOTHER guy just above him who did the EXACT same thing -- then posted the "solution", which was simply MASTER RESET < the VERY next step he wouldn't do because he thought his phone was "bricked". Two people in a row not following the directions. Their phones were NOT bricked.

Or people who tried to flash this who weren't supposed to -- but even they didn't actually brick their phones.

See? NOT bricked.

However, there were others who did mess up their phones by UNPLUGGING them during the conversion update or restarting them in the middle -- or other silly stuff. So, don't do something like that, please.

This thread has been going for over a year and THOUSANDS of people have used this procedure.

[LG V30 Guides, News, & Discussion] ChazzMatt:
90% of people have no problems.

9.9% have issues like Dev Patched LGUP can't recognize their phone, and there's troubleshooting tips to fix that.

For the 0.1% of the others most do something stupid, like not following the directions.

I don't want to talk about bricking phones because this procedure doesn't brick phones.

Yes there are ways to fix bootlooping. In fact your phone WILL bootloop after Step #2 (Nougat), until you do Step #3. < READ that again. It's part of the process. Bootlooping is not bricking. Then you stabilize it with Master Reset, and go on to most recent US998 Oreo. Make sure you know what Master Reset is, it's NOT regular factory reset.

You're sort of making this so much harder than just actually doing it. ;)

Did you ever read the instructions yet and download the TWO Nougat and Oreo US998 KDZ you'll be flashing, and install Dev Patched LGUP yet?

All right, just to be sure:

First i install the lg up patched, then with the phone connected flash to us998 using "dl partition", then i do master reset, then i flash to oreo using "upgrade", and then i do the same but with the most recent oreo update. Right?

And one last question: after i am on us988 can i go back to vs99620j?

Thank you man
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, if you ever wanted to go back (not sure why, since you are not a Verizon customer) but you would just flash this KDZ:

[VS996][STOCK][OREO]LG V30 Verizon VS99620j_00_0305_ARB00.KDZ

I hesitate to even tell you this.... but some people have been able to just flash VS996 straight from Oreo to Us998 Oreo via Partition DL -- without having to flash Nougat and do the Master Reset, then upgrade to US998 Oreo.

I hate to tell people that because then EVERYONE want to try it for their model and it doesn't work, except for VS996 (and even then only a couple have done it and told me):

But since you are freaking out so much, I'll try to make it a little easier for you. ;)

HELP!

Hi guys,

I have an LS998 which I was trying to downgrade from the July 1st security patch so I could root the device. I flashed US99820a_04_0330.kdz per the instructions at the start of this thread. After completion, the phone was in a bootloop so I did a factory reset from the stock recovery. This allowed the device to boot. The phone will start up and after making it the the second screen (where it tells me there is no sim card) it will reboot. I have tried flashing it again with no success. I searched for LS998 firmware but have been unable to find any in .kdz format, only twrp .zips.

I have no idea where to go from here. Any and all help will be greatly appreciated. Thanks in advance.

J
[LG V30 Guides, News, & Discussion] ChazzMatt:
Sounds like you didn't follow the instructions, if the first thing you flashed was US998 20a. :confused:

Read

the instructions

again. Seems you totally ignored step #2 and skipped to step 4.

Also the instructions do NOT say to do factory reset. It's Master Reset in step #3. Again, it's IN the instructions.

If you actually follow the Frankenstein instructions, you will have success. ;)

You're not going to find any LS998 KDZ. Sprint doesn't release full image KDZ, only partial image OTA updates. AT&T does the same with their H931. The TWRP-flashable zips are "ROM" devs have painstakingly hand-built from stock firmware so Sprint and AT&T customers can have recent firmware by installing through TWRP, like a ROM.

Are you a Sprint customer?
[LG V30 Guides, News, & Discussion] jonasritt:
No, I am not a Sprint customer. I just use the phone on wifi, no mobile data. So I tried to flash it a few more times to get it working, but unfortunately I made it much worse. Now the phone seems to be bricked. I cannot get it turn on, charge, or enter in to download or recovery. There is just no response from the device to either connecting to pc or a power source- or- any combination of button pressing. I hope you may have some ideas to save it, but I'm thinking I really screwed it up. Thank you for taking the time to reply. I really do appreciate it.

I have downloaded a qualcomm tool called QFIL. This application does see the phone and I believe it will flash it for me. I need some advice on using QFIL, settings etc, and also which files to flash. I know I'm propbably getting a bit annoying, but I really need some help. Thanks a lot.

It seems if you try to do this method when the phone has a passcode on it you will not be able to master reset.
