LG V30+ won't load Oreo at the final step

Hey ChazzMatt, I'm a noob who's been following the WTF instructions as carefully as I can.

I started with an up-to-date sprint LG v30+, and followed steps 1 and 2 (including the frankenstein method) to unlock the phone and get TWRP working. At step 3 I think I missed something, cause doing what you described brings me back to TWRP when I try to reboot to system. It's supposed to load 20h into stock rooted oreo, right?

are you sideloading Magisk? or is it in internal storage/usb/sd

do you format or clear the cache or do anything before (or after) you do the back to back flashing?

searching around XDA, people talk about clean vs dirty flashing for ROMs. some of those clean flash instructions mention flashing the TWRP installer after every ROM, which doesn't make sense to me. Also, do I need GApps?

Thanks for doing all these writeups. I feel kind of out of my depth
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Let's take one step at a time.

All I am stating right now is from Section 6 of the WTF instructions:

When you finish Section 6 of the WTF instructions, you were on US998 20a or 20b. TWRP was working and you had Magisk 18.1. You had also flashed the encryption disabler and root disabler files. During that process you had either sideloaded Magisk and those two addition files or you had them on microSD card -- because you had to reboot to TWRP from within TWPR and also reformat your internal memory where you type YES. I cautioned people to NOT wipe out their OS, but they do need to reformat internal memory. (This is why I recommend a TWRP backup be made because some people wipe too much and have no OS.)

If you are not sure, go back and read Section 6 of the WTF Instructions -- especially the "More TWRP Actions" section.

At this point you finally rebooted to your US998 Oreo OS. AND you had hopefully installed the Reboot Recovery app (and given it root permission) so you can get to TWRP easily from your OS.

You would want to boot to the 20a/20b OS to make sure everything worked and you set up your phone.

THEN, you are ready for the next step which would be updating to most current Oreo 20h.

You boot into TWRP, and only wipe the two caches. No reformatting.

Then flash 20e, 20f, 20g, 20h and Magisk 18.1 (Important you stay on that for now -- any higher version doesn't work well with these Oreo TWRP flashable zips -- and important you reflash that before rebooting or you won't have root). Since you didn't reformat internal memory, these files are all stored on your phone.

Then reboot the phone.

_______________

If the phone keeps bootlng to TWRP instead of system, maybe you accidentally wiped out your OS or maybe you are not using Magisk 18.1?

If you plug the phone into PC while in TWRP, it acts like a thumb drive/flash drive. You can drag files from PC to phone. They may end up in the basement/root folder of the phone internal memory. Drag 20e, 20f, 20g, 20h and Magisk 18.1 to your phone and reflash them all back to back, then reboot.

___

No, you don't need nor want GAPPS on stock firmware. Already has those services and apps.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] xahova:
I was using magisk 18.0, which is what's linked in the WTF post #193. I dunno if that would be a problem or not.

I think I wiped the OS. And this is the part where you groan, cause I wiped the internal storage backup I made too. Looking back on it, that was definitely a dumb decision on my part, but USB OTG wasn't working for some reason, and I hastily assumed that internal storage backups would be safe/separate from a wipe.

TWRP still works, so how can I get an OS working on the device? Am I ****ed?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
18.0 is fine.

Read the next paragraph:

Again 18.0 is fine. It's just your can't have any Magisk over 18.x for these Oreo TWRP flashable zips.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Don't believe such trash. ;) See screenshot of authorized LG Devices. Do you see any US998 on that list? That's the LG website crap website that doesn't know what they are talking about.

LG Bootloader Unlock Code is NOT the preferred method for US998 and it's NOT officially supported by LG.

Back in 2018, I did Bootloader Unlocked my authentic 64GB Open Market US998 through LG website, but you have to know how to "hack" the drop-down menu for LG website. LG added the IMEI for one Open Market US998 variant to their database and NEVER even posted on their website. They never released an announcement.

We found out about it. It's old news from 2018.

The 64GB Open Market US998 sold by AUTHORIZED 3rd party retailers like B&H Photo is the ONLY US998 you can Bootloader Unlock using that method. You have to provide IMEI and Device ID to LG to PROVE you have that device or you will NOT receive the unlock code.

It cannot be U.S. Cellular US998, it cannot be ANY US998 V30+ or V30S, it cannot be US998 converted from another model. Do you understand?

Whereas WTF handles ALL ALL ALL V30/V30+/V30S in the world EXCEPT for T-Mobile H932.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
I owned three Quarks. Fantastic phone. BHB27 kept them alive. Changed his username a couple years ago, but that's how I know him.

USS98 is among the easiest, as it already has fastboot flash commands.

I have both 64GB V30 and 128GB V30+ USS98. I have both authentic Open Market US998 V30/V30+ as well as converted LS998 V30+ to US998 V30+.

Simple for LG V30 "JOAN" (code name like Quark). You just TEMPORARILY flash US998 to early OREO 20a or 20b firmware, then run the "WTF" fake Bootloader Unlock Code.

Then you install TWRP, reformat internal memory, flash two root related files to disable LG crap, and install Magisk last.

Then you can update to newer firmware.

Read the WTF INSTRUCTIONS in web browser, not an app. Print them out of you can.

It's a decision tree -- if you have this variant, do this. If you have that variant, do that. There's two dozen V30 variants around the world. So that's why the Instructions look complicated. They're not. By Section 5 EVERYONE is now at the same starting line... ;)

* Section 5 is actual Bootloader Unlock

* Section 6 is TWRP and root

* Section 7 is Troubleshooting Tips
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] xahova:
this didn't work.

after it failed, I reflashed TWRP from the bootloader and tried to do everything in step seven again, but now Magisk gives me ERROR: 1. I dunno if dm verity or root check disabler would do that though.

I can't seem to fix that magisk error. Even using ADB to reflash a new downloaded copy of TWRP.img doesn't work. Using a new copy of magisk 18.0 doesn't work either. I feel very dumb and stuck.

Edit for clarity.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] xahova:
Progress! I used LGUP to flash 20b using download mode. Bootloader is already unlocked and I have a copy of android that works again. I can do steps 6 and 7 but correct this time.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] mon0theist:
Just checking in, still chugging along on rooted 30b, have there been any more Pie updates (especially TWRP-flashable ones :P )? Or did the blobs ever get updated/fixed so that LineageOS can be flashed without having to go back to Oreo? I saw the post in Q&A that there will be no official Android 10 release which doesn't surprise me but I'd like to stretch this phone out as long as possible with LineageOS. Thanks in advance!

EDIT: Just realized I posted this in the wrong thread sorry lol
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] damadikaz:
It is stated in the thread that I have to flash 20e zip, then 20f zip, 20g zip, 20h zip back-to-back when I just unlocked bootloader from downgrading method. Does it only applies to TWRP flashables only? I mean is it fine if I just flash 20h KDZ right after 20a?

I flashed 20h KDZ over 20a, but i still can't boot LOS16. what did I do wrong?

======

EDIT: My device is US998 V30+. I use the H930 build in the LOS thread.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] PNT5V:
I'm in 10c. Am I able to flash straight to 20h or do I need to flash 10d then 20a then 20h, or just 10d to 20h?

I don't care about unlock stuff

And also, I am trying to flash Pie. If I get stuck at logo, can I easily hold the power button to turn off and easily go to Download Mode to flash Oreo, or if not, is there any combined button to go to Download Mode, or let the battery drain for the logo to disable and then access, or simply smash it?

And if I am able to access to Download Mode, do I have to flash 20h and then 20a, or go straight to 20a, in case I really need to do unlock bootloader
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
If you are flashing KDZ, which is full image, you can go straight from Nougat 10c to whatever you want. You don't need to flash other in between.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] TPMJB:
On topic, I extracted the modem from the 20h build for use in Pie. My Pie build of Havoc is flawless so far except for one, minor glitch. For some reason when I used this modem, my fingerprint reader started acting weird. I have to touch the reader just right for it to register my fingerprint.

Truly strange.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] larciel:
I'm having trouble installing xposed framework and device ID changer on Pie so I'm moving back to Oreo.

US998 from Pie to Oreo 20e is best way?

It says to install Magisk v18.x on OREO TWRP files. Can I update to latest magisk v21 after that?

what'd be best way to install xposed framework on Oreo?

~~~~~~~~~~~~~~~~~~~~~

just flashed 20e and magisk v18.1 . Magisk is not installed!?. I flashed Magisk after 20e, reboot into recovery and flashed again just in case.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Need to install Magisk 18.x before flashing any of the TWRP flashable zips.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] larciel:
thx Chazz.

Just flashed v19 I had and it worked.

xposed oTOH is a pain to get working...
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] mpicasso:
Did the modem from 20H fix the problem? Back on 20H, stock, trying to decide if I want to stay, go back to Havoc, or upgrade to 10. Preference would be to go back to Havoc, Pie version.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] TPMJB:
I either replied to you or another person in a different thread. I ended up deleting the fingerprint file in the system so it would populate a new one when I installed Havoc. This *should* fix the issue, but I think I screwed it up somewhere because it didn't. If someone can comment on the exact process I'd be appreciative.

It fixed Wifi, but my fingerprint reader is still not as good as it used to be.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] mpicasso:
What was going on with your WiFI? The only Havoc-Pie “concern” I had (definitely no problems) was the fingerprint and how long it took for my phone to respond, if it actually did.

Even with the fingerprint reader causing frustrations, considering what is currently available, I will deal with my V30 for a little while longer. OnePlus 7Pro is still going for $500+, S8/S9/Note 9, all have their typical Samsung issues; only other option for me is the Pixel 2 or 3, as the 4 has no fingerprint. Amazing how well this phone still runs, this far out (probably should go knock on some wood or at least hop on Swappa and get looking for another one!!!).
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] TPMJB:
Oh, that was very early in our Android 10 development and I couldn't figure out how to get wifi working. Simply flashing the 20H modem fixed it.

OnePlus refuses to put in either an SD slot, headphone jack, or both (I forget) so that's gonna be a no from me, dawg. Same with any "Google" phones.

I'm looking into upgrading to the V50 or G8, as root is veeeeeery close with both phones.

With fingerprint, someone else posted the "fix" in a reply to me. I haven't tried it so I don't know if it works: https://xdaforums.com/mi-5x/how-to/rooted-fix-fingerprint-upgrade-to-t3897423

Edit: Does not fix it for me
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] mpicasso:
Yes, the OnePlus lost headphone jack after 6. Not sure they have ever had SD card, as I have not always religiously followed. But most of these phones are pushing 128 to 256GB, so for me, SD card is not as important. And for headphones, not using anything spectacular with my phone (Sony WH-1000MX3’s or B&W PX7’s) so if I migrate away from LG’s DAC, will be looking at this BT badboy.

Honestly, my problem has been the lack of development and though I realize some has been due to a lack of root/locked bootloaders, there are some phones that get absolutely NO LOVE (will never forget my HTC Inspire...)!!! Before I even consider pulling the trigger, XDA/Telegram are the 1st places I look, to see how they are progressing. I have neither the time, nor patience, to learn how to do what most of these developers are able to do, and though thankful, will bypass a perfectly good phone that does not have an AOSP-based ROM.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] TPMJB:
SD is very important to me, as I had the terrible Google Nexus 5X that decided to just die on me one day. My storage was encrypted. There was no way to get my data. I used the freezer trick several times and got it to boot long enough to pull my necessary data. Never again will I buy a phone where the company is removing features to save money.

We're not Apple users.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Worth re-posting. No, we are not Apple iSheep.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] tech_infinity:
They are removing sd card not to save money but to make us spend more for higher storage variant.

I mean even 100$ phones have sd card support, there's no reason why flagship phones shouldn't have SD card support.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] mpicasso:
Would love a V50 or G8 and honestly have been looking at the G7's as well. I do not keep much on my phone, as I am much more dependent on cloud storage (or even a NAS at home), but I get the desire/need for an SD card. Personally would struggle more by not having a headphone jack as I do appreciate wearing cans while listening to this phone.

Your last comment was priceless...We're not Apple users. I have an iPad that I use for surfing, running quotes, etc. Would consider a Surface Pro, but when my iPad does everything I NEED it to do (including be a royal PITA), why spend the additional $5-600??? I do appreciate the closed ecosystem for Apple and for many, it works great! But their menu system is unlike no other; so much of their stuff is proprietary; even their desktops are getting to the point that you cannot upgrade without using GENUINE Apple hardware. I can build a desktop, for under $3K, that will let me do EVERYTHING their $4-5000 desktop will do, including but not limited to videoediting.

For me, personally, I am in the $12-1400 range, dependent upon cost of video card.. .find me an Apple desktop at THAT price!

Sorry to get off on a tangent but the more I use Apple (kid has iPhone, as well), the more I truly dislike using their products. Definitely not an Apple "user" here, either.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] TPMJB:
If you're spending over 1k on a desktop nowadays, you are absolutely blowing your money. Even a GOOD gaming PC will cost you sub $800. That is if you spend the 30 minutes to connect parts in a computer case. Mine cost about $800 in parts and I have 64gb of ram. It's massively overkill.

Why bother with a surface pro or an iPad when you can get a very good laptop for much cheaper? I never understood the tablet fad as I have a computer in almost every room I inhabit, and my cellphone otherwise. A tablet is just a less powerful laptop with no keyboard lol
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] mrsubway:
I'm a tech. I just put together a phenomenal desktop system for about $600. Unless a PC is at NASA, you don't need 900GB of RAM and a 56.8ghhz processor complete with Liquid Nitrogen cooling system. ?

You also shouldn't pay $25,000 for a $700 equivalent computer because it has a picture of a rotten fruit on the side with zero expansion slots and no upgradability.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] mrsubway:
I apologize for being off topic, but I need some advice. I want to upgrade, preferably to another LG. I don't want dual screen. Also, all the ones I see are Sprint unlocked, AT&T unlocked, etc. I want something international that I can unlock the bootloader and root. Should I just start looking at Pixels? Any recommendations? Thanks.

Mods. I understand if this gets deleted or moved.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
V35 and V40 can be bootloader unlocked and rooted with exploit. See those XDA forums for more information.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] mrsubway:
Yes, but Amazon has the carrier specific variants. I'll check.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Those can be bootloader unlocked. Since you would be using an exploit. That's why I specifically said "exploit" versus official LG bootloader unlock. ;)

For V35, see here:

[LG V30 ROMs, Kernels, Recoveries, & Other Developm] mpicasso:
Pricing my desktop out at around $1400 (not purchased yet). Part of my increases were needing a fairly decent graphics card and a CPU that can multi-task very well (running Adobe programs...). Also, boot drive is a 250Mb Samsung M2, along with 2-2TB backup drives for pictures currently being worked on and hotswappable drive bay to back them up, off of computer. Running 32 Gb RAM. Probably overkill but coming from a Phenom X4, 16 Gb, that has been dying a slow death for a while.

Laptop - unfortunately, same predicament. Finding a screen with fairly decent color accuracy pushes me over the $1K mark almost immediately, and that is with Dell or Lenovo, heavily discounted. Move over to Clevo/Sager/MSI, and I am in the $16-1700 price range. I also need something with a pen (client signatures) so it was either buy a touch screen, Surface, or iPad. As much as I am not a fan of Apple, the screen in the Air is phenomenal and it costs around $450, $50 for keyboard, and $8-100 for pen. So I can work on what I am supposed to be doing AND ger some editing time in, all while away from home. Not great solution but $500+ cheaper than a laptop...
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] mpicasso:
What are you looking for in your next phone? SD card? Headphone jack? Best camera? Super bright screen? Most colorful screen? There are phones out there with locked bootloaders that can be rooted.

Why are you wanting to achieve root? I would love another LG but development seems to be lacking on the V35 or V40. Because I am very fond of Havoc and AOSP/Lineage ROMs, I stay on this phone.

Does mean anything above 18 as well? Or ONLY an 18 build
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
18.0 or 18.1. Use the one attached to the WTF Instructions post.

After you get 20h TWRP flashable zip installed, and get it rooted with 18.x, THEN you can update Magisk to current version. But you can't start with a newer version. And if you went to another Oreo TWRP flashable zip, you would have to temporarily downgrade your Magisk first back to 18.x.

I ended up having no way to get LgUp to work.....so I just clean flashed 10c, then E, then H and tried Magisk 21,3 but it didnt flash.....but when I went back into TWRP and reflashed it, it worked....seems to be fine and working well....and then ended up with some issues so I tried it again

went TWRP 10c to E F G H.....tried Magisk 18.1 flashed success but never showed up with magisk manager and no root

[LG V30 ROMs, Kernels, Recoveries, & Other Developm] mime64:
So, I had followed the original frankenstein instructions to flash twrp and I actually had US998, but had to switch to LS998 to use sprint. Now I'm moving to a different carrier whose SIM card wont work with LS998 and I attempted to move back to US998.

However, I'm not sure I followed the right instructions.

I used LGUP Dual to flash US99820e_02_0910.kdz and I'm getting boot warnings and errors about encryption and the instructions want me to reset the phone.

Which set of instructions do I fall back on now? This thread? The WTF thread? Or do I suck it up that I've lost everything on the phone and go with the reset?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] schwinn8:
The warning screen during boot is just to scare you because you don't have a stock phone. It doesn't mean anything is wrong... it's just a scare tactic. As ChazzMatt says, it's a badge of honor to say that you're not bound by the dumb carriers... so don't worry about it. For that matter, read it carefully and you'll see it's just saying what you already know - that your phone is not stock. That's a GOOD thing in most of our opinions!

[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
You can Master Reset without turning the phone off. You can force it to reset during the boot up animation before it boot loops again. It's just easier if you can turn the phone off.

Thank you so much for your fast reply. I was worried I really screwed it up so I took it to a local cell repair shop for flashing, but I'm going to try to downgrade to oreo again, to unlock the bootloader.
