Is it possible just paste a link showing Frankenstein for me to start? I was using Frankenstein methods to convert my H933 to US998, just in case there is another guide from Frankenstein for converting back to H933.

Mine is H933 converted to US998 20h with unlocked bootloader and twrp. Still trying to go back to full stock H933 (seems there is no easy way for low tech persons like me to revert it back to H933 and keep root). Please help. Thank you in advance.

Thanks a lot for sharing your experience. My phone is H933 converted to US998 20h with unlocked bootloader and twrp.

* update, seeing post #5 in the link, so unlocked bootloader etc is not achievable, after reverting back to H933, I update my questions as below. Can you or any friends please help? Thank you.

https://xdaforums.com/lg-v30/how-to/using-lgup-crossflashing-t3780969

- is there any way to revert back to H933 full stock?

- if yes, how?

- what will be the differences between full stock H933 and your H933 with US998 modem etc?

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

Edit: Successfully done.
[LG V30 Guides, News, & Discussion] SaiLas:
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
[LG V30 Guides, News, & Discussion] ChazzMatt:
There is only one Frankenstein thread, and I wrote the Instructions. If the post is by me, that's it.

Google: Frankenstein instructions XDA ChazzMatt

There's no separate guide to convert back. You just follow the Frankenstein instructions but substitute the opposite firmware.

The Frankenstein instructions are to convert ANY eligible North American variant to another. I just wrote it specifically to convert to US998 Oreo -- as that's the most popular -- but people have used the same Instructions for Verizon VS996 or Canada H933.
[LG V30 Guides, News, & Discussion] David X:
Thank you for your directions. I just reworded your instructions for my case (to revert US998 20h rooted back to Stock H933). Would you please check for me one more time? Thanks.

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".

3) Master Reset. (post 101) (to stop the incessant bootlooping)

4) Flash Oreo H933 in LGUP Partition DL mode selecting ALL.

Later I can update to newer Pie H933 firmware using LGUP DL PARTITION selecting ALL, right?

5) DONE.

I found out that my V30 is a frankeinstein H931 turned into US998. my search here seems to state there is no way i can convert back to H931 coz AT&T doesnt release any KDZ. i've tried everything in this post to update and all have failed! All the processes work except when i install pie, bootup ends at thinq screen. Even twrp in fastboot says "cannot open twrp recovery" any ideas?

If there is a way i can get back to H931 i would appreciate as i prefer OTAs no matter how long they take
[LG V30 Guides, News, & Discussion] SaiLas:
Sorry to hear that, I do not know where you got the error.

First step its Frankenstein convertation, it was done by many and problems should not to be.

Try hold down Vol.up button with connected cable to PC for switch into downloadmode

[LG V30 Guides, News, & Discussion] ChazzMatt:
Well, you're never going to get OTAs. ;)

Even if you were on native AT&T H931 firmware, unless you are an AT&T Wireless customer you would not get OTA updates. This is why 80% of the people flash from AT&T H931 (or Sprint LS998) to US998 in the first place. So they can get updates! Neither AT&T nor Sprint provide updates on NON-customers. Are you an AT&T Wireless customer?

The other 20% do it so they can unlock bootloader and root! Which also precludes OTA updates.

But I hate partial image OTA. I prefer to manually flash my full image KDZ or TWRP-flashable zips...

If you cannot update to Pie using any of the methods, then you have to wait until LG delivers a more stable US998 Pie KDZ. We never had this trouble with Nougat or Oreo KDZ.

Or you can convert to Canada H933 and have Pie right now. But you're still never going to get OTAs. ;) Next time Canada H933 gets a Pie update, you will have to manually flash via LGUP.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Than you. I added link to this method in post #6 with the other workarounds.

If I was writing it, I would include download links to the various KDZ files. ;)

The only part I'm confused about is you say NOT to do Master Reset -- but then right after that you say to "immediately do hardreset using the buttons". Isn't that Master Reset? But then you say "keep hold Vol. up button".

Master Reset

is "Press and hold the Power and Volume down buttons.", so what is this "hard reset" which uses Volume UP button?

Or is it Master Reset, then change to Volume Up button after everything is reset to get to Download mode? With phone off, Volume Up + USB cable plug in gets you to Download mode...

I'm not criticizing in any way. Thank you for contributing another method! Like I said, I've linked it on page 1 of this thread. I'm just asking for clarification because if I don't quite understand, then others may not either.
[LG V30 Guides, News, & Discussion] SaiLas:
I apologize, I read somewhere that it’s called Reset, when you do it via buttons and must wait until phone turns on completely with welcome screen.

The trick is just that we must prevent it from fully turning on.

[LG V30 Guides, News, & Discussion] ChazzMatt:
OK, then we're not doing an official Master Reset. Sort of a modified Master Reset?

Something like this? Or even slightly different from this?
[LG V30 Guides, News, & Discussion] SaiLas:
Im replaced *master reset* with

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

We do everything exactly on points*

Look now, everything seems clear
[LG V30 Guides, News, & Discussion] An`Droid:
This is most strange procedure, I have ever seen.

Double cross flashing, no boot, no Master Reset....

BTW, what the reason to do the step 1, if we do step 2 in REFURBISH mode?

Does anybody tested US99810d instead of H93310h on step 1?
[LG V30 Guides, News, & Discussion] SaiLas:
Strange, but only this way I updated verizon and 931 v30. You can try first 1-3 methods
[LG V30 Guides, News, & Discussion] ChazzMatt:
That's what Method #1 is, sort of.

Unless you count not letting it boot up completely from Master Reset.
[LG V30 Guides, News, & Discussion] An`Droid:
Not exactly.

Method #1

From US99820h downgrade to US99810d then PartitionDL right to US99830b

Method #4

From US99820h cross flash to H93310h then REFURBISH back to US99820h and then UPGRADE to US99830b

Big difference with Method #1

But I do not understand what Step #1 (in Method #4) really does.
[LG V30 Guides, News, & Discussion] ChazzMatt:
It changes all partitions to Canada H933. Then you change back. Really wipes EVERYTHING.

While you can Frankenstein to and from Canada H933, it's been pointed out several times in other threads the partition system is very different.

So, when you come back it's very fresh install.

Hi, Chazz

vs996 is normally for Verizon network so if someone converts this into US998 running Pie, do you think if it will still work with Verizon or not?
[LG V30 Guides, News, & Discussion] ChazzMatt:
It should.

I know Oreo US998 works fine for Verizon. My sister and her husband are running two former LS998 V30+ on Verizon with US998 20h.
[LG V30 Guides, News, & Discussion] newbe1droidx:
Yes it will work, but wont have every band verizon uses. There might be a way to flash us998 over vs996 and keep verizon radios but i dont know how to do that. Maybe someone who does will chime in....
[LG V30 Guides, News, & Discussion] zfk110:
the reason I was trying to do that so I can use the same vs996 on both GSM/CDMA network after converting to US998, since pure vs996 won't work with GSM, yes you can convert vs996 to US998 then back to vs996 just flashing vs996 base TWRP flashable stock rom by Chazz
[LG V30 Guides, News, & Discussion] ChazzMatt:
Just to clarify, [MENTION=6815443]JohnFawkes[/MENTION] makes those VS996 TWRP-flashable zips, donating his time and efforts. Between he and [MENTION=3138121]seadersn[/MENTION] (our TWRP dev), they make the zips for

US998,

Verizon VS996,

Canada H933,

India H930DS,

EU H930 and

Sprint LS998.

(The latter is very difficult because Sprint doesn't release full image KDZ.)

I post them in my KDZ threads (except for Sprint, of course) alongside the full image KDZ.

I'm not a dev, but more communicator of helpful information. ;)

The US998 has these bands:

US998

CDMA: 800 MHz CDMA

2G GSM: 850/900/1800/1900 MHz

3G UMTS (HSPA): 850/900/1900/2100 MHz

4G LTE Bands: 1/2/3/4/5/7/12(17)/13/20/25/66

VS996 has these bands:

VS996

CDMA: 800/1900 MHZ CDMA

2G GSM:	850/900/1800/1900 MHz

3G UMTS (HSPA): 850/900/1900/2100 MHz

4G LTE bands: 2/3/4/5/7/13/20/46/66

Yes, there are some differences. One additional CDMA band and one additional LTE band VS996 has the US998 doesn't. Overall, however, the US998 has more LTE bands.

As I said before, both my sister and her husband are running two former LS998 V30+ converted to US998 on Verizon with US998 20h firmware. They recently switched from AT&T to Verizon and they are very pleased with how their phones are working on their new network.

End of this year (2020), Verizon is dropping CDMA, so don't obsess over that extra CDMA band. :)
[LG V30 Guides, News, & Discussion] David X:
Thank you and all the developers for your time and help.

Sorry for my noob questions:

- Does it mean if my phone is H933 converted to US998, I will have US998 bands to use?

- Can you please also list H933 bands?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes.

US998

CDMA: 800 MHz CDMA

2G GSM: 850/900/1800/1900 MHz

3G UMTS (HSPA):850/900/1900/2100 MHz

4G LTE Bands: 1/2/3/4/5/7/12(17)/13/20/25/66

CANADA H933

2G GSM: 850/900/1800/1900

3G UMTS (HSPA): 850/1700(AWS)/1900/2100

4G LTE bands: 1/2/3/4/5/7/8/12/13/17/20/25/29/30/66

The main advantage US998 has is fastboot flash commands, for bootloader unlock and TWRP installation. Canada H933 seems to have 3 more LTE bands, while USS98 does have CDMA (but most people outside the U.S. don't need that).
[LG V30 Guides, News, & Discussion] David X:
Thank you for the information and explanation.
[LG V30 Guides, News, & Discussion] ChazzMatt:
I flashed a former LS998 V30+ -- which had been converted to US998 V30+ -- on to Canada H933 for my brother-in-law who lives in Brazil. Wasn't sure which carrier he used, but one of the Brazil carriers has now added LTE band 8. So, I wanted him to have the most options.

Phone was not bootloader unlocked nor rooted, so just Partition DL (with all partitions) to Nougat H933, Master Reset, and then Pie H933.

It's harder to convert to H933 with unlocked bootloader and keep TWRP. There's a LONG instruction post for that.
[LG V30 Guides, News, & Discussion] David X:
Interested in knowing that. I want to have one of bands 3/4/5/7 for local use, and also have one of 39/40/41 for travelling purpose. I checked online that H930/H931/H932/VS996 can meet both requirement. If this is the case, which model would be easier to convert to with less risk of bricking? Currently my phone is H933 converted to US998. 20h. Thanks in advance.
[LG V30 Guides, News, & Discussion] xduser1:
Hi ChazzMatt,

Need your advice on how to proceed.

Have a US998 (believe it is US Cellular version). In January last year, used your instructions to downgrade (using KDZ) and unlock bootloader, installed TWRP. Using TWRP installed 20D.zip, 20E.zip, 20F.zip, 20G.zip. Loaded PixelExperience_h930-9.0 ROM and have been running it since (rooted with magisk). (20H was not available then, so I never had it on this phone). PixelExperience rom has it’s set of issues which I kind of live with, but I think I am ready to move to the official Pie now (I saw your warnings, in regards to permanent changes, but after having 9.0 for a year now, don’t really want to go back to the 8.0. Also don’t have time to mess with custom ROMs at the time so I think stock might do the trick for me since it's fairly slim and everything works).

What is the recommended path to proceed? Since I am already on Pie, is it Ok to just wipe system partition and install 30b via TWRP leaving data alone? Perhaps not perfect, but worth a try? Or should I re-install 20D, 20E, 20F, 20G, 20H, and then 30b? Or 10d and then 30b? Use TWRP zips or KDZ?

Read too many suggestions/instructions, and now just confused.

Thanks.
[LG V30 Guides, News, & Discussion] ChazzMatt:
AT&T H931 supports this:

LTE bands: 1/2/3/4/5/7/12//20/29/30/38/39/40/41/66

The only problem is you would either need to buy a carrier unlocked AT&T H931 and keep it on that firmware OR flash this

TWRP-flashable zip (ROM) AT&T firmware.

to get all those bands. But really that ROM is for AT&T customers and possibly may carrier lock your phone to AT&T while running that firmware. I don't know for sure.

You are also mentioning EU H930 which cannot be changed whatsoever, at least bands. None of the H930 (H930, H930G, H930D, H930DS) variants can change bands. So, you can't mix and match bands with those.

Frankenstein

is only for North American variants, and even then does not include T-Mobile H932. T-mobile H932 can NOT be changed to anything else. Trying will hard brick it, due to different RSA encryption.

The North American variants (excluding T-mobile H932) have an amazing chameleon ability to convert to other North American variants, using

Frankenstein method with Dev Patched LGUP.

.
[LG V30 Guides, News, & Discussion] ChazzMatt:
I don't think just flashing US998 30b TWRP-flashable zip without wiping data would work. Yes, you could try.

This first US998 Pie KDZ is wonky. It's actually made for U.S. Cellular -- so you may be in luck there. ;) But it's the first US998 KDZ where it's not "universal" for all US998. In the past, I supplied both "Open Market" and "U.S. Cellular" KDZ because there was no difference whatsoever. LG still has not released a US998 Open Market Pie KDZ. (I have a theory WHY -- because Sprint has not yet approved their LS998 Pie firmware, and Open Market cant be released until ALL U.S. carriers get Pie -- but it doesn't make our situation here less infuriating.)

Anyway, many people seem to get stuck on the LG/ThinQ logo when flashing this Pie KDZ. I didn't -- but I'm pretty sure that's because on my backup V30+ I went straight from US998 Nougat to US998 Pie. (My daily V30+ phone is still on stock rooted Oreo firmware with Magisk and Xposed mods.) Most people don't want to downgrade to Nougat and just want to take a chance updating from Oreo to Pie, hoping it will work. Then, when it doesn't they've already flashed Pie firmware (even if not successful) and their options are the methods in post #6.

After you try your method and IF it doesn't work, then you will need to try the

workaround methods in post #6

of this thread.

Good luck!
[LG V30 Guides, News, & Discussion] 1031982:
That is a sound theory, and as you said, it's infuriating.

It's a shame LG won't just release an open market KDZ for the US998 as it's an unlocked device. Isn't part of the point of an unlocked device to get updates sooner and more frequently?
[LG V30 Guides, News, & Discussion] ChazzMatt:
LG is beholder to carriers for sales. In the U.S., I seem to be the only person who doesn't buy carrier branded phones. Haven't for the past 9 or 10 years, for me and my wife. I've even imported phones from other countries... Whereas everyone else makes regular trips to their locsl carrier stores! If it's not there, people won't buy.

So, not only did Open Market get released MONTHS after the carrier versions (so as not to offend the carriers), then Open Market US998 got Oreo last after the carriers variants. And now Pie.

LG official excuse is Open Market variant is supposed to work on all carriers, so they need carrier feedback on their respective firmware before tweaking/releasing Open Market firmware.

Sprint says their V30 Pie build didn't handle VoLTE correctly, so they refuse to sign off on it. I assume they're testing others since then?
[LG V30 Guides, News, & Discussion] 1031982:
Hopefully they are.

I don't completely buy LG's excuse. If that was the case, security updates shouldn't have an issue being pushed out. However, they don't seem to come out at all.
[LG V30 Guides, News, & Discussion] mon0theist:
Accidentally posted this in the Oreo thread by mistake:

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!

Needing help for US99810c

Well, I have a LG V30+ US99810c. I have no idea if it was either transformed from LS998 or an unlocked version or whatsoever, because the one I bought is a second-hand, and the original user has no idea what kind of variants on that phone.

I am trying to update my LG V30+ into Pie version, but currently stick on Nought 10c. I literally read lots of threats like updating 10c to 10d then go straight to 30b, or updating to 20a then to b to c to whatsoever and then updating to 30b.

I don't care about rooting or twrp stuffs, but can anyone experience upgrading that phone to Pie? If yes, please tell me if upgrading to Pie could highly get bricked or not, or I could just flashing to Oreo for the god of safety, and if you didn't get brick, plz tell me which tips are you using? I literally saw a bunch of complaints because of their phones being bricked, neither Oreo to Pie nor Nought to Pie nor TWRP worked, so I'm completely fear :(.

People said LG couldn't optimize the software well so I got to update to Pie for actual experience of the powerful chipset

I'd glad if people succeed in upgrading from 10d to 30b cuz I have already downloaded them, and my storage is not allowed. And also I am fking lazy to download 6-8 KDZ file just for 1 update

I downloaded LGUP_DualMode stuffs, LG Bright, LGUP and install whatever required files for the upgrade

( also do i need to flash other version like H933 or just stick in US998? Prehaps many people got brick because of flashing into unrelated version so i don't want to mess up entirely )

( and am i able to flash back into 20h or other oreo ver if the flash is unsuccessful if i never flash oreo? )
[LG V30 Guides, News, & Discussion] ChazzMatt:
Nobody has bricked their phone updating to Pie.

What is happening is often trying to flash to this wonky US998 Pie KDZ, the installation doesn't finish and they get stuck on the LG logo. That's not bricking. They just then reflash US998 Oreo 20h. There are 5 different workaround methods for people who for whatever reasons want to update to Pie. See post #2 and post #6. Yes, at least two require Bootloader Unlock and TWRP.

Since you don't seem to know what you are doing, it's probably better you just update from Nougat to US998 20h Oreo for now.

I'm still on (rooted) 20h Oreo myself on my main phone, so it's not a consolation prize. Oreo US998 20h (last Oreo released for US998) is stable, battery life is longer than this Pie, charging is faster than this Pie.

There's nothing about LG stock Pie right now that's inherently better than last stable LG stock Oreo.

Use Dev Patched LGUP and use Upgrade mode to get from Nougat to Oreo. See these instructions:

https://xdaforums.com/lg-v30/help/extremely-wrong-lg-v30-t4042777/page4

[LG V30 Guides, News, & Discussion] PNT5V:

And btw, since LG V30's battery is not removeable, how am I able to access to Download Mode to let LGUP detect my phone, if my LG logo is still hung there? At least I need to know order to access by pressing combo buttons or something
[LG V30 Guides, News, & Discussion] ChazzMatt:
You are hung on LG logo right now? You tried to update to Pie KDZ?

Try pressing power button for 60 seconds.

Try Master Reset.

After that, if you go read those instructions it specifically tells how to enter Download mode manually.

Right between step 5 and step 6.
[LG V30 Guides, News, & Discussion] PNT5V:
My phone is not currently hung lol. I even read the instruction word to word carefully.

[LG V30 Guides, News, & Discussion] ChazzMatt:
Can you explain better -- with punctuation? Your run-on sentences are hard to read.

Did you or did you not install H933 Nougat? Or did you mistakenly try to flash H933 Oreo instead?

You will have incessant bootlooping if you try to install H933 Oreo KDZ over US998 Oreo.

You need to Master Reset and flash H933 Nougat KDZ.

If you did flash H933 Nougat successfully, then at this point you still need Master Reset to stop the bootlooping.

The instructions for Method #4 actually tell you to do Hard Reset BEFORE any bootlooping can began. I admit I do not know the difference between "Master Reset" and that guy's "Hard Reset". You'll have to ask him. I did not write Method #4.

I'm just guessing what you did because I'm piecing together what you wrote.
