Thank you very much for your time and help. Just try to ensure I am fully understand the steps before I start the process. For post #6 you mentioned, I thought that is for converting from H933 to H988. Now I just need to follow your instructions in post #542 as listed below, to convert it back to H933. I noticed your instruction says for 'NOT bootloader unlocked', while mine is bootloader unlocked. What special steps do I need to follow in my case?

However if you are NOT bootloader unlocked (and don't care about doing so), and you don't specifically NEED US998 Pie firmware -- but just want LG V30 stock Pie, you can Frankenstein your phone to Canada H933 firmware and have LG stock Pie.

See the Frankenstein instructions, but you will basically be going the OTHER direction, from US998 > H933.

0) Download and install the Dev Patched LGUP firmware attached to that post. Read the installation instruction carefully and uninstall any prior version of Dev Patched LGUP. (It's the same version found in this US998 Pie KDZ thread you are in right now, but they are both different from the Dev Patched LGUP found in the Oreo threads.)

1) Using Dev Patched LGUP, REFURBISH your US998 to US998 Nougat KDZ

2) Partition DL (all partitions) US998 Nougat to H933 Nougat KDZ

3) Master Reset (to stop any bootlooping)

4) Partition DL H933 Nougat (all partitions) to H933 Pie KDZ

5) Master Reset again, just in case.

You are now on Canada H933 Pie firmware

Post #6 on the main page of this thread has three different methods to try. Two of them REQUIRE unlocked bootloader and TWRP.

See screenshot below. Go to post #6 and read those methods.
[LG V30 Guides, News, & Discussion] David X:
Post #6 is only talking about methods to solve the boot issues if I understand correctly. Here is my situation, I have converted H933 to H988 with bootloader unlocked several months ago. Now my goal is to go back to H933 and keep the bootloader unlocked. In order to achieve this goal, what method or link should I follow? Can I still use your instruction in post #542 (I don't think I can after read instructions several times)? Please help. Thank you in advance.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Forget post # 542. ;) That's only for someone who wants Pie and doesn't care about bootloader unlock.

There's actually a whole thread devoted to H933 that tells how to flash to H933 Pie firmware and keep unlocked bootloader and TWRP.

https://xdaforums.com/lg-v30/how-to/guide-us988-oreo-to-h933-pie-stock-rom-t3978121

See post #1 of that thread. It's a little complicated...
[LG V30 Guides, News, & Discussion] DJBhardwaj:
Hi everybody! Is it possible to flash the US998 Pie firmware on a Verizon V30 (VS996)? The Verizon firmware has a lot of pesky bloatware that I don't want.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes. If you're bootloader unlocked, use the US998 Pie TWRP-flashable zip file. See Installation instructions in post #2.

It's you're not bootloader unlocked and have TWRP, best to downgrade to US998 Nougat KDZ first (Partition DL, all Partitions, then Master Reset), then flash US998 Pie KDZ (Refurbish mode). Use the Dev Patched LGUP from page 1 of this thread. Read the installation instructions carefully, and uninstall any prior version.
[LG V30 Guides, News, & Discussion] David X:
Thank you very much for the link. I read instructions several times. One question, now my phone is converted to US998 30b, can I start from step 1, or do I have to downgrade it to Oreo rom first?
[LG V30 Guides, News, & Discussion] ChazzMatt:
You should be able to do it from US998 Pie, if it works with USS98 Oreo.

Any questions you have you can ask in that thread. I'm not intimately familiar with those details.

Help whith my v30+

Hi im hoping u could help me, i have a v30+ that i flashed from LS998 to US998 then upgraded to pie but i now want to unlock my bootloader but i only found how to do it for EU version but i cant seem to find any posts on how to do so for the US variant.

If u could assist me it would be much appreciated.

Thanks in advance.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Hmmmm... You posted in this US998 Pie KDZ thread -- but didn't actually read anything on the first page, huh? Then say you can't find any posts on how to root US998? Very strange.

So read post #1 of this thread. (See attached screenshot.)

Or read all of post #3 of this thread.

Or even the V30 ROOT STICKY GUIDE?

ROOT YOUR V30!

https://xdaforums.com/lg-v30/how-to/root-v30-t3927154

Also in the Frankenstein instructions (converting LS998 to US998) are links for the WTF INSTRUCTIONS to unlock US998 bootloader and root.

You're welcome.

____

Another tip, NEVER upgrade to newest firmware until you know how to unlock bootloader and root. Luckily you can still downgrade (temporarily) to get to the early Oreo "WTF" bootloader unlock exploit -- but what if you couldn't? Many OEMs put in anti-rollback in new firmware, just to prevent using now-patched exploits.
[LG V30 Guides, News, & Discussion] philiptwoholes:
Help whith my v30+

Thanks for the quick response. Unfortunately im a noob doing whats noobs do best which is asking dumb questions and screwing those up too. I meant to ask how or if i can just downgrade from pie to oreo on my ls998 converted to us998. When i use the dev patched LGup i get a message saying something about the wrong laf or something like that. Cant remember the exact message.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Read post #3 carefully. It explains how to downgrade from US998 Pie to the proper US998 Oreo (20a or 20b) for bootloader unlock and root.

You need to use the version of Dev Patched LGUP in this thread.

Not sure what you used to convert LS998 to US998, but the Oreo KDZ threads have a different version of Dev Patched LGUP which doesn't work once on Pie. The version in the Pie KDZ threads version work on all LG V30 firmware. (There are reasons to keep the other version around, which I won't explain here.)

Uninstall any prior version of Dev Patched LGUP. Read the Installation instructions carefully.

I recommend using Refurbish mode. If you choose Partition DL mode, choose all partitions.
[LG V30 Guides, News, & Discussion] jamey090:
Any news about the new KDZ ?

Waiting for it.
[LG V30 Guides, News, & Discussion] PacSensei:
yes, I also waiting for the blessed kdz, but apparently, our hopes lie in the V30s hahahaha
[LG V30 Guides, News, & Discussion] ChazzMatt:
It's about time for it -- been about 90 days since the last release.

We will continue to get Pie updates. The US998 V30S is no different whatsoever from the US998 V30+ except it has more RAM. Please don't believe the misinformed people who think the V30S will somehow get LG Android 10. I mean, LG can give Android 10 to whatever phones they want, but the V30 "Joan" launched with Nougat in 2017 and already has two letter OS upgrades -- Oreo and Pie.

The US998 V30S is merely a V30+ which was updated to Oreo before released, and then all the other V30 got the EXACT SAME Oreo update. V30S was a marketing gimmick to try to deflect from early Samsung Galaxy S9/S9+ which had newer Snapdragon 845. V30S (with Snapdragon 835) is just another V30 variant -- was NOT really a "new" phone.

US998 V30S runs the exact same firmware as all the other US998 V30/V30+. As proof, the V30S does NOT have Treble, whereas all NEW phones LAUNCHING with Oreo or later are required to have Treble. V30S was merely a V30 Joan phone which was updated to Oreo and then released -- but did not LAUNCH with Oreo (or it would have had Treble).

So, all the phones LG has announced will get Android 10 LAUNCHED with Oreo and have Treble, and have Snapdragon 845 or newer. V30S does not qualify.

If LG wishes to give Android 10 to the v30, they can. It's just not required.
[LG V30 Guides, News, & Discussion] mrsubway:
I just want a Pie I can update to without doing 45 hours of flashing. I'm guessing that won't happen, so I'm sticking with Oreo until I just get a new phone.
[LG V30 Guides, News, & Discussion] cityneversleepz:
I'm so sick of all this Sprint stuff. If I switch to say T-Mobile or Verizon I'll be able to get over to US998 or flash AOSP roms without having issues like SMS and MMS not working, am I right? I think when switching carriers if I'm on Stock LS998, I'll be able to activate on the new carrier, right? Don't know where else I can ask this.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Especially T-Mobile on US998 firmware. You don't need CDMA any more but LTE Band 66 (on US998 firmware) will be very helpful on T-Mobile.

Verizon won't normally activate new SIM card on non-branded phone, especially US998 or former Sprint LS998. Some reps will do it anyway (my brother in law just switched two former LS998 now USS98 V30+ to Verizon, but he found a rebel behind the counter). Normally you need an already-activated Verizon SIM card to swap in.

Also all AOSP ROMs have Verizon bug where after rebooting you need to make a phone call to get data.

Whereas T-Mobile Wi-Fi calling even works on US998 firmware.

Heyo, is it possible to flash this to a completely stock US998U currently on oreo? Been sitting here waiting on 9.0 to come to the unlocked V30+ but LG can't seem to get their updates in order. I bought a note10+ because I'm done giving LG shots, but now that this v30 is a backup I'd like to get it on pie if possible.
[LG V30 Guides, News, & Discussion] ChazzMatt:
See posts #2 and #6.

I had no problem flashing this KDZ straight to my backup V30+. But others need the workaround tips in post #2 and #6.

On my daily B&H PHOTO Open Market US998U (V30+) I'm still on Oreo on purpose. I have it rooted and modified just as I want.
[LG V30 Guides, News, & Discussion] cmrntnnr:
This Pie rom is technically for US Cellular branded phones and not the open market US998 models like sold through bhphoto. Although it can be flashed, there is an important loss of functionality; VoLTE does not activate on Verizon. It would be interesting to hear from others if the same problem exists with other carriers. The reason is to decide if flashing a vendor specific rom makes sense vs sitting tight with Oreo. VoLTE works fine on Oreo 20h dated Mar 1, 2019. It is a sad state of affairs that the open market US998 has not received either an Oreo or Pie update in 10 months. Hopefully it happens soon.
[LG V30 Guides, News, & Discussion] cityneversleepz:
sounds like t-mobile is the way to go then. So From stock sprint rom, I guess I get a new sim card, and what if I want stock Pie on t-mobile service; do I kdz over to US998? I'm confused about how I get there.

edit: just found the t-mobile stock Pie thread. I see that's where I probably need to wind up. Still not sure how though.
[LG V30 Guides, News, & Discussion] ChazzMatt:
No! Do not flash any T-Mobile H932 firmware on your non T-mobile phone. Surely you've seen all the T-Mobile H932 cross flash warnings? You will brick your phone.

You can use US998 firmware for T-Mobile.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Sprint is the hold-up, I believe for the B&H Photo Open Market US998 KDZ. Last March, Open Market was the last of the Oreo updates because it had to wait on all the carriers first. Sprint still hasn't certified their V30 Pie upgrade (Sprint V40 Pie just got released this last weekend).

[LG V30 Guides, News, & Discussion] cmrntnnr:
I've been following the discussion in the forum about timing of release of Pie for the LS998 and the reason for the delay. It was amazing to see a representative from one of the companies go on the record.

Wow, I hadn't paid attention to the v40. Releasing a phone like that without Pie is a serious competitive failure. These behaviors are not helping their bottom line, https://www.google.com/amp/s/mobile.reuters.com/article/amp/idUSKCN1RH0GD

Many months ago you had posted about an agreement Google had with phone manufacturers to provide timely Android updates for certain models. The v30 was one of them. Did it expire or were the open market US998 and LS998 not covered?
[LG V30 Guides, News, & Discussion] cityneversleepz:
Ah, switching carriers got me confused. Now its all making sense. Focused on Sprint for so long and not seeing the bigger picture UNTIL now.

Should I kdz over to US998 or wipe in twrp and flash it?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Nothing has changed about the Google "Enterprise Recommended" agreement nor the requirements...

However it all went off the rails mid-year when LG tried to wait until "end of Q2" to deliver Pie instead of delivering it earlier in the year. Once they started working on Pie they stopped work on Oreo -- except for that strange "30a" Sprint LS998 OREO firmware delivered a couple of months ago.

Pie was so messed up that LG didn't even release their first EU H930 30a PIE and then they quickly KILLED EU H930 30b, deleting it from their LG Bridge servers.

Sprint says their current LS998 Pie update is crap and won't certify it and release it, due to VoLTE issues.

AME region also hasn't received Pie yet.

Google hasn't punished LG in any way for violating the "at least 90 days" security patch updates.

No news about new KDZ?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Any news will be posted here.

No further U.S. Cellular US998 Pie KDZ yet and the Open Market US998 Pie KDZ has still not been released.

I believe the latter is due to no Sprint V30 Pie being released yet for LS998. When Open Market US998 got Oreo it was only AFTER all the U.S. carriers got Oreo. All the U.S. carriers have not signed off on Pie yet -- Sprint is the last holdout. Sprint V40 got Pie finally about two weeks ago, so their V30 should be next. THEN Open Market US998? I don't know. I can't figure out LG's dysfunctional behavior.
[LG V30 Guides, News, & Discussion] jamey090:
Is there any method to update the US998 to pie without unlocking the bootloader?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, see top of post #2, and all workarounds in post #6. Only two of the four methods listed require unlocked bootloader.

As I've stated several times and will state again, on my backup V30+ (locked bootloader) I went straight from US998 Nougat to US998 Pie. But the difference was I wasn't on Oreo and tried to go to Pie. So, your best bet is to downgrade to Nougat and try to update to Pie.

If you have already tried to go from Oreo first to Pie and failed (hung up on logo), you are probably screwed. You've already permanently changed your phone because Pie half installed. Some people have been able to use the post #6 locked-bootloader method (downgrading back to Nougat to take another run at it), but most do not succeed. After that the only ways are through using TWRP options.

Depends on how badly you need US998 firmware. The other option for bootloader locked phones is to convert to Canada H933 Pie, which is still carrier unlocked firmware. If you use that path, make sure you do it right. Have to follow the Frankenstein instructions, and roll back to Nougat first and cross there.

On my daily phone, I'm still on rooted stock Oreo 20h firmware myself. I have Magisk and Xposed mods for what I want and don't feel like setting up my phone all over again, with Pie stuff that may not be compatible with my mods. For instance, automatic call recording, dual speaker mode, LG7/V40 Pie camera features, etc.
[LG V30 Guides, News, & Discussion] jamey090:
How to flash Canada H933, please tell me the details process, please.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Uhm, read my last sentence you quoted? You follow Frankenstein instructions. But instead of flashing to US998, you flash from US998.
[LG V30 Guides, News, & Discussion] jamey090:
US998 pie doesn't work then what to do?

Is there any problem with flash Canada H933?
[LG V30 Guides, News, & Discussion] ChazzMatt:
No, there's no problem.

Two people did it an easier way:

If you are already on US9998 20h, then steps 5 and 6 are all you need. You would Partition DL to H933 Pie, but omit the Modem, Xbl and Xbl2 partitions on the list. You would still have US998 modem but H933 Pie software.

Or you can go full blown Frankenstein and convert everything to H933 Canada -- going back to US998 Nougat, then H933 Nougat, then H933 Pie. Follow the Frankenstein instructions. I'm not going to re-post them here.
[LG V30 Guides, News, & Discussion] Kacike27:
The steps I have set are the only ones I have been able to do to go from Oreo to Pie.

When installing Pie for the US998 model, the phone stays in bootloop.

If I follow the steps to pass my model to H933, the phone runs out of mobile data, so it is necessary to go from US998 Oreo to H933 Pie doing it as in step 5 and 6.

Otherwise I can not go on foot with the mobile data working.

I see that more people by following the Frankenstein Phone steps, run out of mobile data when installing the KDZ from H933 to US998.

Following the steps I have set, the phone manages to keep the mobile data working after moving from the firmware of the h998 to the firmware of the H933 model.
[LG V30 Guides, News, & Discussion] newbe1droidx:

[LG V30 Guides, News, & Discussion] SaiLas:
For people who want to switch on US998 30b and have problems

METHOD #4​

no difference, locked or unlocked bootloader

simple and safe, working 100% ( others didn't work for me except METHOD #3, but the download mode does not work there )​

You must be on US998 firmware, no matter, NOUGAT or OREO and you needs files:

1. H93310h_00_OPEN_CA_OP_1124.kdz https://lg-firmwares.com/downloads-file/12260/H93310h_00_OPEN_CA_OP_1124

2. US99820h_00_0318.kdz https://lg-firmwares.com/downloads-file/19157/US99820h_00_0318

3. US99830b_00_0902.kdz https://lg-firmwares.com/downloads-file/20723/US99830b_00_0902

4. LGUP patched https://xdaforums.com/attachment.php?attachmentid=4828349&d=1569503757

Steps:

LGUP must recognize your V30, V30+ like US998 model, if not - first flash any US998 firmware in any possible way, reopen LGUP, reboot phone, reconect usb-cab, etc

Its very important, again,

LGUP must recognize your V30 like US998 model

if Yes - do the following ( it will take about 10 minutes )

do not close LGUP and don't let phone turn on completely until the process is completed!

We do everything exactly on points

1. Flash H93310h_00_OPEN_CA_OP_1124.kdz via LGUP using Partition DL mode ( check all partitions), when phone automatically restarts - immediately do hardreset using the buttons, keep hold Vol. up button, we get download mode again

2. Flash US99820h_00_0318.kdz using REFURBISH mode, when phone automatically restarts - just wait "Erasing" screen and now immediately keep hold Vol. up button, we get download mode again

3. Flash US99830b_00_0902.kdz using UPGRADE mode ,

at this stage the phone will boot normaly and you finally get 9.0 Pie.

Next step is optional, but strongly recommended

4. Flash US99830b_00_0902.kdz again using REFURBISH mode, and now you have clearly fully stock.

Done ! Congratulations.
