NOTE:

Four workarounds. Two require unlocked bootloader. If none work for you,
1) make sure you are on the correct Dev Patched LGUP from this thread. (See post #2 for Dev Patched LGUP and follow the installation instructions. Uninstall any prior version of LGUP.)
2) Look over these steps again, make sure you followed them all. Do NOT skip steps!

If it STILL doesn't work, there are no more answers after this. Just flash back to US998 Oreo 20h wait for the next US998 Pie KDZ.

4 WORKAROUND METHODS TO SUCCESSFULLY UPDATE TO US998 PIE FOR THOSE PEOPLE GETTING STUCK ON ThinQ/ LG LOGO
_____________

METHOD #1 -- WITH OR WITHOUT UNLOCKED BOOTLOADER


I've been reading reports from other LG models (like LG G6), where LG has LG Bridge downgrade the phone back to Nougat first before then updating to Pie. LG Bridge uses full image KDZ, temporarily downloaded to PC.

So I suggest trying to Partition DL back to Nougat KDZ, Master Reset, then Partition DL to Pie KDZ. Here are the steps...


0) Using Dev Patched LGUP from this thread, REFURBISH back to US998 20h. Turn off phone, go into Download mode.

1) Flash US998 10d Nougat KDZ via Dev Patched LGUP using Partition DL mode. Select ALL partitions.

2) Master Reset. This is NOT Factory Reset.

3) Boot up to Welcome screen. Turn off phone, go into Download mode.

4) Flash US998 30b Pie KDZ via Dev Patched LGUP using Partition DL mode. Select ALL partitions.

5) Master Reset. This is NOT Factory Reset.

• If you did not unlock your bootloader before doing this, then you bootloader is still locked -- because that's what you want. Finished. Set up your phone.
• If you had unlocked bootloader before doing all this, you will still have it. Boot to ADB, and PLEASE follow these instructions for re-install TWRP and root!!

_____________

This next method by @EstebanxZ uses parts of #1 & #3 (oldest method which works). I'll will rewrite when I get time, but right now just quoting verbatim what worked for him:

METHOD #2 -- NEEDS UNLOCKED BOOTLOADER



_______

This third below is our oldest method which works, but is most complicated.

METHOD #3 -- WITH TWRP

We have a working method for people with TWRP who are having trouble getting across the line for Pie. Most people have no problems updating. I didn't. However, for those who are having issues, there's a workaround, but you need TWRP installed and make sure you're using the Dev Patched LGUP from THIS thread. (See post #2 for Dev Patched LGUP and follow the installation instructions. Uninstall any prior version of LGUP.)

For users with TWRP who get stuck on ThinQ/LG logo:

0) Using Dev Patched LGUP from this thread, REFURBISH back to US998 20h. Flash TWRP recovery via fastboot. Turn off phone, go into Download mode.

1) Flash Canada H933 10h Nougat via Dev Patched LGUP using Partition DL mode -- EXCEPT for Recovery partitions, to keep TWRP. Do NOT choose "all" partitions! Omit/UNcheck the Recovery partitions.

Reboot. You will probably have lost download mode, but you've prepped your phone, corrected any partitions -- and you still have TWRP.
____

NOTE: For the next step, you will need to use the much-hated "hardware button dance" to boot to TWRP custom recovery, since H933 firmware doesn't have fastboot flash commands to boot to TWRP from PC. You also no longer have root at this stage, so you can't use the excellent Reboot Recovery app or NOXX Advanced Power Menu app...

You will need to IMMEDIATELY start the "hardware button dance" just time phone reboots. This is the ONLY time I will ever tell you to use the "hardware button dance". Any other time, it's stupid and ridiculous and there are better ways to boot to TWRP custom recovery.
____

2) Flash US99820e TWRP-flashable zip to get back Download mode. (Remember you KEPT TWRP recovery partition!) IF it doesn't boot, make sure you are on Magisk 18.1. Oreo TWRP-flashable zips normally require Magisk 18.x.

3) Then REFURBISH to US998 20h KDZ.

This will temporarily wipe out TWRP, but give you a completely fresh install. You will still have unlocked bootloader and fastboot flash commands.

4) Now flash TWRP recovery again via fastboot flash commands and then flash the US99830b Pie TWRP-flashable zip. See Section 6 of the WTF instructions if you need to remember all the steps to install TWRP, etc.

"Phone booted immediately on pie and everything is working great." - TESTER

You are now on US998 30b Pie!

After all that you can flash to other compatible TWRP-flashable zip if you wish.

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.

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.

 

[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.

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.

EDIT : Never mind. I found it in one of your threads. You really are one of the most helpful people in my life. Thanks a lot.

1. First back on 99820h via partition dl
2. Reopen lgup. Lgup must see your phone like us998 model,
so reopen lgup. Next steps from my instruction, in no case do not close lgup

I did this and now after the LG V30 screen, my phone says "No command". Please help.

Sounds like you may have forgotten the master reset:

Not sure which part of the process you are in but check for this

 

[Skyhawk1207]

This problem happening while flash US99820H in refurbish mode, what's the solution?

Edit: Successfully done.

Could you please tell me how?

Does this ROM allow us to get VVM, VOLTE and Wifi Calling up and running on SPrint?

 

[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

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:

Well actually, I'm using the phone in India so the carrier is Airtel

Can't seem to get it to work still

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.

Oh the lucky part is, I do have a rooted phone, and it is a H930 cause this phone was actually bought in the US. I'll try entering the details. Thanks a lot!!

Keep in mind you have the dumpster fire variant of the V30!

The dumpster fire variant? What's that mean and how worried should I be?

 

[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

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.
