Thanks for the reply man. I've already tried that one but i will try again.

Here's the process that i did before.

1. Update my VS996 to Pie via System Update then got stuck to boot logo(though this going for a while now since the 1st release of pie last september but i manage to downgrade it to oreo a couple of times)

2. This time after i got stuck while updating i tried the Frankenstein Method to convert it to US998 but got the error at 50% in LG UP so i reflash it over and over again :D using Refurbish, Upgrade and DL Partition but it still stuck with 50% and still on boot loop.

3. so I tried to go back VS996 with Nougat. afte reflashing it still have the same error and now stuck with bootloop and wont enter in Download or Recovery Mode.
[LG V30 Guides, News, & Discussion] Night_1:
I don't know... It worked for me... But I had to be really fast when I did it and not let go of the volume up until I saw download made on the phone screen

Hope the above helps you.

Also because you mentioned Pie... Just want to explain something to others. These instructions don't cover updating to Pie. It only covers converting any North American variant (except for T-mobile H932) to US998 Oreo. But you have to go through US998 Nougat first. (Also works to convert to other North American variants like H933, etc.) But, you don't need to update to Pie on native firmware before using Frankenstein to convert to US998 since you have to down convert back to Nougat anyway.

US998 Pie is very wonky. There's nothing about these instructions that will help you update to US998 Pie. ;) In the US998 Pie thread, I have several different workarounds to update to US998 Pie -- and about half of them need unlocked bootloader and TWRP to work. :rolleyes:

I really only recommend to update to Oreo US998 20h only. If you insist on updating to US998 Pie, AFTER you get to Oreo 20h, then go read

post #6 of the US998 Pie KDZ thread

and decide if that's what you want. I'm still on rooted stock US998 Oreo 20h myself (with Magisk and Xposed mods). And my wife, mother, sister, brother-in-law are all on bootloader locked/unrooted US998 Oreo 20h.

Well, I've been on version 9 (pie) ever since John Fawkes came out with the zip for it. It seems to work fine for me. I really haven't had any problems that I can associate because of pie rom, but, don't really know. I've wanted to go try the 996 version, but I use the hot spot quite a bit now, where before I didn't. And I'm pretty sure that 996 doesn't have the hot spot working.

I've also recently (last week or so) started thinking about trying a custom rom, but I don't want to mess up my phone settings. I've been on 998 pie for quite a long while now, gettin' the itch to change. :).

I probably would have never updated to pie because of Chazz 's recommends, but, I think I upgraded before he came out with the warnings.
[LG V30 Guides, News, & Discussion] ChazzMatt:
My warnings are more about the US998 Pie KDZ, which technically is for U.S. Cellular UNLIKE the US998 Oreo and Nougat KDZ. LG never released Open Market US998 Pie KDZ, because Sprint never approved the LG Pie for LS998. That was needed before Open Market (all carriers) US998 Pie could be released.
[LG V30 Guides, News, & Discussion] dias05:
Thanks so much everyone.. maybe updating to local pie is the error that ive made. I've already tried the hold all button then the screen went black but the computer recognizes it as usb though you cant access the file.. I'll try the other mentioned fix.. Thank you so much.. i'll update if anything works around.

---------- Post added at 05:04 AM ---------- Previous post was at 04:42 AM ----------

im on VS996 and i have problems with my phone cant make incoming and outgoing calls(data and messages are all ok) here in the philippines. so i tried to update to pie or to US998 to check if its only an OS problem. updating to pie and getting bootloop is a common to me and fixing no big deal. maybe the error that i've made is updating to pie and changing firmware while stuck in loop.. should have fixed it first before US998.
[LG V30 Guides, News, & Discussion] Cristhianv26:
Hi! i´m currently using a VS996 on stock Pie and i would like to unlock bootloader so i can install TWRP and flash an android 10 custom ROM. As far as my understanding goes, I need to Downgrade to Oreo VS996, then Frankenstein it to US998 oreo and then i can now unlock bootloader (post 193) and carry on flashing ROM. I know i´m simplifying a little bit but am I getting something wrong or am I missing a step or something?
[LG V30 Guides, News, & Discussion] ChazzMatt:
You don't need to downgrade to VS996 Oreo. You need to flash to US998 Nougat, Master Reset, then update to early US998 Oreo 20a or 20b. It's all in the Frankenstein instructions.

The WTF instructions also tell you what to do, but you have to read carefully in web browser not an app. Every section is important. Lots of decision tree questions. If you have VS996, then EVENTUALLY you'll need to flash early Oreo US998, but first go through Frankenstein to convert to US998.

Section 7 of WTF Instructions are troubleshooting tips.

Does anybody know if US998 firmware has Greek as a default system language?

Thanks!
[LG V30 Guides, News, & Discussion] ChazzMatt:
No, US998 does not have Greek language as option. I have a spare brand new in box US998 V30+ and I just checked at boot up for system language options. See attached screenshots.

What North American variant do you have?

Frankenstein is only for North American variants. It's completely convert one North American variant to another, to:

1) carrier unlock (SIM card unlock/network unlock) certain carrier locked variants like H931 or LS998, or

2) to acquire fastboot flash commands for bootloader unlock and root it, or

3) to get specific carrier LTE bands/firmware/features.

Sometimes Frankenstein is only used temporarily -- like for bootloader unlock -- then people convert back to their original North American variant firmware.

While flashing to US998 is most popular because of the North American variants only it has fastboot flash commands AND is carrier unlocked, sometimes people flash to Canada H933 or Verizon VS996. Canada H933 is also carrier unlocked and actually has 3 more LTE bands than US998.

You can NOT Frankenstein any V30 variant which is not North American. Doesn't work.
[LG V30 Guides, News, & Discussion] granazias:
Thank you very much for all your answers.

My question about Greek language,was because i've already purchased a brand new LG V30 H931 AT&T unlocked,which i am about to have it in my hands in a few days,despite the fact that i live in Europe.

As far as i've understood good,if i Frankenstein it to US998 i will be able to use it without problem.

Am i saying something wrong?

And basically in all the smartphones,Greek language is referred as "Ελληνικα" and not Greek.

Maybe that's why you didn't see that option?

Are only these 2 screenshots with language options available on your phone?
[LG V30 Guides, News, & Discussion] ChazzMatt:
No, but some people get Korean V30 carrier variants or H930DS and think they can get US998 LTE bands by converting (Frankenstein) those variants to US998. This conversion does not work with non-North American variants, and also doesn't work with T-mobile H932.

Gives me peace of mind to know you actually have a relevant North American variant.

I looked specifically for that. That was also why I included the screenshots to show you exactly what I was seeing. ;) I know the languages are written in that language. That's why it says Deutsche instead of "German". ;) So, Greek would be written in Greek.

Of course. Maybe you have to ask, but come on. ;)

If I've gone to this much effort to charge and get my spare V30+ US998 out of the box, you should know I would include all the language options if I showed any screenshots (besides writing). If I showed two screenshots, I would not stop there if there were any more. Also, notice those two are OVERLAPPING. So, you are seeing top to mid-list and bottom back up to mid-list.
[LG V30 Guides, News, & Discussion] granazias:
Chazz sorry if these i wrote before,look like a doubt for what you've seen on your phone.

I was not trying to insult you if this is what it looks like,i wouldn't do that of course,you are willing to help me with my questions so i would be very rude and disrespectful at you if i ever did that.

Probably my English are not as good.

So,no Greek language option on US998,but i can live without it.

Thank you very much for your help.

I'm stucking in a very odd situation. I flashed my VS996 to 99810d and it always show "charging slow" when everytime plug in a pc. Tried different cables, hubs, pcs' even replaced the charging port, nothing work. But when I swap my others H931 motherboard in, it works just fine with all the exact same components. Pretty sure this is a software problem but since adb does not work at all, what can I do?

[LG V30 Guides, News, & Discussion] ChazzMatt:
Thank you for starting this Frankenstein thread over two years ago! Has helped a lot of people!

It confirmed reports of what we were seeing in early 2018 -- like LS998 somehow being converted to Canada H933 V30+ (which doesn't exist naturally). You helped us figure out how to do it and I wrote more detailed instructions couple of weeks later. But if you hadn't started the thread, who knows if it would have all happened.

Then, about a month later [MENTION=6158380]TxanMoe[/MENTION] discovered the early Oreo "WTF" bootloader unlock exploit and many of the North American variants had to use this new Frankenstein method to get fastboot flash commands for that.

But even for people who don't want bootloader unlock and root, Frankenstein is an effective tool to convert almost any North American V30 to another, for carrier unlocking, to get different bands, and other reasons.
[LG V30 Guides, News, & Discussion] Moriatier:

Hi.All.I have cross flashed LG v40 Hong Kong version Rom Android 9 with the Korean Android 10 using lgup.

THE Rom was installed but I lost radio.no signal. So then on the advice of a friend I flashed partition dl modem a and modem b from a European version 9.and when the phone rebooted it shows security warnings and says all slots are unbeatable. Any way to put oh in fastboot mode so that lgup can identify.Any easy way out.thx

Uhmm... In the V35 forum you just posted in the "AT&T V35 won't work on Verizon" thread.

Your problem has nothing to do with Verizon, so people are going to probably ignore that.

You need to create a new thread, explain you understand you don't have a V35 that you have a V40 -- but that they are very similar and you hope someone can help you, since no one in the V40 forum will help you. Then state your problem.

Good luck!

I have an unlocked AT&T V30 that has Verizon VS9960k flashed. I'm trying to flash to a generic US998, but with every kdz I try I get an error in LGUP: "Error: 0x6004, CrossDL VS996>US998."

I know I have encountered this before and have gotten around it, but I can't remember what I did. Could somebody point me in the right direction?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Which US998 KDZ are you trying to install? US998 is carrier unlocked North American Open Market, which works with all carriers.

What VS996 firmware do you have? Did you mean to type 20k? Because there is no just VS996 "0k".

It sounds like you're not using Dev Patched LGUP or not the latest.

Make sure you have the Dev Patched LGUP attached to the

Frankenstein instructions

. Uninstall any prior version and re-install with the instructions in Frankenstein instructions post.

Make sure you're using Partition DL mode.

Technically you should go through US998 Nougat (like US998 10d) first when cross flashing (or Nougat of whatever North American variant to which you are converting). Then update to newer firmware. The one exception -- which I hate to even mention -- is VS996/US998. But if you are having problem, from VS996 to US998, go to US998 Nougat, Master Reset, then update to newer firmware.

I have ls998 V30+ - wanted to unlock via crossflash into us998 - after I've made that it stuck on V30 logo. When I try to perform factory reset via volumeDown+Power - "Factory data reset is disabled by Kill switch"...

So I flashed AS99820b_00_0328.kdz now I can boot into the phone, but when I installed back US99810d_01_0411.kdz it still stuck back into LG V30 logo, since I can't do the using Master Reset -- using buttons:

I get "Factory data reset is disabled by Kill switch"... I looked for McAfee apps I don't see any.

What should I do now?
[LG V30 Guides, News, & Discussion] ChazzMatt:
That kill switch is also because somebody reset their phone before logging back in to Google account. Maybe the previous owner?

When you were able to flash the AS998, were you able to log into your Google account?

Here's two more suggestions when someone who last posted about this a year ago:

Try reflashing the 10d via Dev Patched LGUP Refurbish mode when you get back into Download mode.
[LG V30 Guides, News, & Discussion] zfk110:
I can do factory reset within the settings, I can log in and out from Google account, but that Kill Switch still there, when I tried to reflashing the 10d via Refurbish mode I got error message saying something failed. That ebay's listing is dead
[LG V30 Guides, News, & Discussion] ChazzMatt:
Try flashing to another Nougat firmware temporarily, via Partition DL mode.. Like Canada H933 or Verizon VS996. Master Reset. Log into Google account if you can, then try to flash US998 10d again.

H993 reflash

Hello thanks for this amazing thread, I am really greatful. I have just purchased a h931 and I was just about to cross flash to us988 to unlock bands for uk use as its not working on my network but I just noticed this post saying h933 has extra bands. So now I'm thinking maybe I should flash to that instead as I do travel a lot so I'm always switching sims. Do I follow the steps the same as us998 but just dowload h993 firmware instead. I've also noticed something about our not been fully released will this affect the amount of bands available for either the us998 or h933 pie versions?

Thanks again :)
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, you can use H933. Go to H933 Nougat first (Partition DL, all partitions), then to H933 Pie (Partition DL, all partitions). You will need to Master Reset after the Nougat flash to stop the bootlooping. Then continue on to Pie.
[LG V30 Guides, News, & Discussion] Jimi.kieswetter:
Ok great thanks :) ive just had a quick look at on lg-firmwares and there's different versions listed for h933, AVC, BLM, RGS & TLS. Does it make any difference which ones I use?
[LG V30 Guides, News, & Discussion] ChazzMatt:
For your purposes they are all the same. For each version number, they are actually all the same image. The md5 numbers will be the same for all the H933 10d, for instance. Then certain carrier specific features are installed if you put in one of the Canadian carrier SIM cards. But it doesn't matter if you had Rogers SIM card and installed "Telus" image. It's identical to the "Rogers" image. The difference comes AFTER installation when it senses which Canadian carrier you are using, if any. If you aren't using a Canadian carrier, then no specific carrier features are installed.

I installed H933 for my brother-in-law who lives nowhere near Canada. Everything works fine.

I am trying to unlock the device. Sorry i dont really know the terminology. I have enabled usb debugging and oem unlock in the developer options of the phone.

[LG V30 Guides, News, & Discussion] ChazzMatt:
The H932PR (Puerto Rico) is totally different from the T-Mobile H932. The H932PR is like the other North American variants -- US998, Canada H933, AT&T H931, Verizon VS996. Whereas, T-Mobile H932 has a different encryption system than any of the other V30/V30+/V30S. LG should have name the the Puerto Rico model the H934 or something, not re-use a number already taken.

IF you indeed flashed T-Mobile H932 firmware over your H932PR phone, it's hard bricked.

We

talk about the H932PR in this thread

as well as the Frankenstein thread. I'm sorry you bricked your phone, but you should have researched first.
[LG V30 Guides, News, & Discussion] poncespr:
Ok. I know I am in the minority here, but just in case anyone else has an H932PR or if this can help in any other way, I decided to just pull the trigger and flashed US998 Oreo via LGUP with DL Partition.

After getting boot loops I followed [MENTION=3250376]ChazzMatt[/MENTION] intsructions to perfom a full reset and am happy to report that everything is ok. No IMEI issues, no radio or signal problems so far.

So, crossflash from H932PR to US998 works.

[LG V30 Guides, News, & Discussion] ChazzMatt:
Do not try to flash European H930 on LS998.

H930/H930G/H930DS have their own threesome going. You can cross flash those with each other.

HOWEVER, there's a rooted T-Mobile H932 out there with parts of European H930 flashed over it. We just don't know which parts. The guy in China uploaded a TWRP backup, but no one could figure it out. To get even crazier, he was using Galaxy S8 TWRP, not even V30 TWRP.

He didn't make it himself, he bought it. So, he doesn't know how it was done.

[LG V30 Guides, News, & Discussion] R800x_user:
Well it seems highly unlikely due to the fact that the h931 is bootloader locked. Even if you cross flash it wouldn't change the bootloader unlock state. But It begs the question what if the h932 cross flashes with a unlocked bootloader to us998 or h930. In order to get it's functionality for the flash commands. I'm just rambling now.
