Hi everyone im new here got all kinds of confused reading things like crossflash and frankenstein method ?.
The cheaper model is the h931 what can be done in this variant?
The us998 is just a bit more money is better just get this one?
Or should just try to get a used h930 European? I'm not English native so is kinda confusing. I would like to try and avoid bricking a phone.

It's quite simple.
* You need a model with fastboot flash commands.
If you don't have a model with fastboot flash commands (US998, H930, H930DS) then you need to convert the phone (Frankenstein) to firmware with fastboot flash commands. When you Frankenstein, you are totally converting it to another variant, include LTE bands, etc. In most cases (VS996, H933, LS998) you can convert back to the original variant AFTER bootloader unlock, if you desire.
* You also need pre-July 2018 Oreo firmware.
If you don't have that, you can update from Nougat or downgrade from newer Oreo to that firmware. After you unlock the bootloader, then you can update to newer firmware or flash custom ROMs. Pre-July Oreo firmware has a FANTASTIC bootloader unlock exploit we call "WTF".
The WTF bootloader unlock/TWRP, root instructions I wrote have a preliminary section to get everyone to that same starting point (fastboot flash command, pre-July 2018 Oreo firmware). Then...
* Flash bootloader unlock code, install TWRP, and root.
* Done
IF you want to flash AOSP ROMs, right now H931/H933 cannot do that, even after converted to US998. But you can bootloader unlock, install TWRP, root. If you don't care about custom ROMs and just want root with Magisk mods, etc, then the H931 would work for you. You would just have to Frankenstein it to US998 first.
ALL V30/V30+/V30S can be bootloader unlocked and rooted. It just depends on where you want to start. The models that already have fastboot flash commands (US998/H930/H930DS) do give you a head start... But I have done both -- used "original" US998 V30/V30+, and I've also converted two LS998 V30+ to US998 V30+ in 10 minutes time, for each.
There are MINT 128GB LS998 V30+ on eBay for U.S. $299, as well as NEW US998 64GB V30 for U.S. $299, and NEW US998 V30+ for U.S. $378.
Thanks alot, one last thing so when i start doing the steps to convert the phone i already need to be on that Oreo exploitable fw?

No. If you convert another North America phone to US998 -- with one exception which I don't want to name -- you have to first convert to US998 Nougat, THEN upgrade to pre-July 2018 Oreo firmware. But I've done two phones like that in 10 minutes time, each. AT&T H931 is North America phone.
SHORT VERSION:
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". Use the attached patched LGUP in this post.
3) Master Reset (post 101)
4) Flash Oreo US998 in LGUP UPGRADE MODE. (Make SURE you are choosing Oreo US998 and not accidentally re-flashing Nougat US998 again!)
(For bootloader unlock purposes, use the US998 KDZ versions with pre-July 2018 security patch: 20a or 20b. You can always update to newer US998 firmware later, AFTER bootloader is unlocked.)
5) DONE.
AMAZON/EBAY/ALIEXPRESS, ETC.
Just answered a guy with a similar question but he was asking about Amazon. I pointed him to this thread...
For most people just pretend it's asking about Amazon/eBay instead of AliExpress. The question and answers are still the same no matter where you buy!
All V30/V30+/V30S (LG code name: JOAN) on the planet can be bootloader unlocked and rooted. Some variants have a head start (fastboot flash commands), which LG removed from most models -- but there's ways to add that back (except for T-mobile H932; it has a different method for root). The North America US998 has fastboot flash commands, so it's one with head start. There's others, like Europe/Africa/Asia H930/H930DS, and I believe H930G and probably H930D.
But of all the North America variants ("Open Market" and U.S Cellular US998, regional carriers' AS998, Verizon VS996, Sprint LS998, AT&T H931, Canada H933, T-mobile H932), LG removed the fastboot flash commands EXCEPT for the US998 (since it's the open market model that is also eligible for official bootloader unlock code, if all the conditions are met). With WTF bootloader unlock exploit, we don't need LG's permission and it's a LOT easier than jumping through all the hoops for the official code -- which I did for one of my B&H Photo Open Market V30.
In recent months I also bought two "mint" LS998 V30+, converted them (Frankenstein) to US998 V30+ and gave them to relatives. It's not hard, I did both in about 10 minutes time. BUT if you have a choice of about the same price, or if that's beyond your comfort level -- then START with one of the models that already have fastboot flash commands.

YES, when you Frankenstein any North America phone to another, it becomes that phone.
Many Verizon customers on here are using former LS998 or US998 converted to VS996 with those full features.
However, you'll probably need an already-activated Verizon SIM card. Many US998 sold on eBay are converted LS998, and Verizon won't activate former Sprint phones even if they are now US998. Where did you get your US998?
Thanks for the reply. I forgot to mention that the unlocked V30 is activated on Verizon already. I just want to add the other features and update the os.

Yes.
When you say unlocked, you mean carrier unlocked or you've bootloader unlocked/installed TWRP/rooted?
You can get to VS996 firmware either way, but the method depends on what you have -- either flashing KDZ with Dev Patched LGUP or TWRP-flashable zips via TWRP.
It's carrier unlocked, not bootloader unlocked.

OK, then Dev Patched LGUP, flashing the latest VS996 KDZ in the VS996 KDZ thread. Use REFURBISH or Partition DL mode.
Thanks for the reply, one more question, after doing the kdz in vs996, will this also allow me to get OTA's from Verizon?

Probably not. Don't know for sure.
But very easy to use LGUP "upgrade" mode every couple of months when a new KDZ is released. Takes 5 minutes. You don't want "upgrade" mode to convert to VS996, but after that you can use it to get updates. Keeps your data -- it's like a manual OTA.
New VS996 KDZ is posted here in this forum and other sites every time it's released, which is about every couple of months.
VS99630c (30c) onto US998 with LGUP?
Does everything in this thread also apply to using Dev Patched LGUP to flash the VS99630c (30c) KDZ onto a carrier unlocked US998?
Thanks!

Yes.
To be safe, you should really flash Nougat VS996 KDZ via Partition DL mode or Refurbish mode, Master Reset, then flash Pie VS996 30C to that phone.
However since it's a VS996 and you're coming from US998, you can get by with skipping the Nougat step. But I hate telling people that, because it's only VS996/US998 which have that loophole.
All other North American variants have to go through Nougat first to cross flash -- unless they're already bootloader unlocked and rooted, in which case they can just flash the appropriate TWRP flashable zip version of that KDZ.
I have a ls998 v30. I want to know if there are some differences between from 20a through twrp flash 20e 20f 20g to 20h and direct REFURBISH to 20h? and when I flash 20h from eu30b the phone Non-stop restart。I have to flash us998 10c then 20a then 20e and 20h。is there a easy way to flash 20h. looking forward to your reply，thank you very much @ChazzMatt

Yes, the difference is the workflow and what is easier.
EITHER do bootloader unlock/TWRP installation, root all in ADB/fastboot in one step, then update via TWRP flashable zips --
OR do part in ADB/fasboot, go do something else in LGUP, then go back to ADB/fastboot. People seem to have ISSUES with ADB/fastboot and once you get TWRP installed, you NEVER need ADB/fasboot again. :good: So, for most people option 1 is better than option #2.
Also the TWRP flashable zips have some premium features already enabled.

I'm going to start from the beginning and pretend your phone isn't already bootloader unlocked (which it may be). Let's just start from the beginning.
You have an LS998.
First you have to Frankenstein to US998 Nougat KDZ (10c or 10d, your choice), as you noted.
Do a Master Reset to stop bootlooping.
(At that point you no longer have LS998, you have full-fledged carrier unlocked US998 with all the US998 bands.)
Then you will update to US998 Oreo KDZ.
* If you don't care about bootloader unlock and root, you can skip straight to from US998 Nougat to US998 20h KDZ. You don't have to first flash Us998 20a or 20b. That early Oreo is only if you want bootloader unlock, otherwise they are useless.
(Remember, we are pretending your bootloader is not unlocked. We are just walking through the steps like you have an untouched LS998. So, let's say you DO want bootloader unlock. So, you would NOT skip from Nougat straight to US998 20h, you WOULD first flash early US998 Oreo.)
* If you DO want to bootloader unlock and root, then you need to flash US998 20a or 20b (the last US998 Oreo before LG blocked the WTF exploit), and unlock bootloader.
Now at THAT point (early Oreo KDZ with fastboot flash commands, bootloader unlocked), you have two choices:
1) because you are already in ADB/fastboot, go ahead and install TWRP and the three root files (encryption disabler, root check disabler, Magisk). And then update to 20H via TWRP-flashable zips. But you MUST flash 20e,20f, 20g, 20h all back-to-back + Magisk again. There were a ton of changes starting with 20f and you need 20e as a good foundation. Flashing 20e, 20f, 20g, 20h TWRP flashable zips you will get all the incremented changes. Just flashing from 20a/20b to 20h you will have problems. We don't make you do this if there isn't a good reason.
OR
2) immediately after bootloader unlock on 20a/20b, get out of ADB/fasboot mode, go flash US998 20h KDZ via LGUP Refurbish mode. Then go back into ADB/fastboot, and install TWRP and the three root files (encryption disabler, root check disabler, Magisk) on 20h.
By doing #2, you skip are able to skip all the successive TWRP-flashable zips -- but you have to deal with ADB/fastoot TWICE. It's usually easier to do it all at once (unlock bootloader, install TWRP).
Also with #2, then you need to install these features below separately -- features which are already included in the TWRP flashable zips:
* Fully enable DTS 3D stereo (root needed)
* LG V30 Lockscreen EXTRA Weather Animations Enabler

Thank you very much for your reply and it has answered many of my doubts. I also read a lot of your previous posts, which has benefited me a lot. I flash eu30b to experience 9.0, it is not a good idea I think. I have unlocked my phone and flash it to 20h. I will wait for us 9.0. Thanks again.
Hello everyone and thank you for clicking my question. I just got my girlfriends LGv30 delivered to me today and wanted to make sure I understand the variant before I go for a bootloader unlock since I got it off of ebay.
So the vendor on ebay says its US998 GSM, this is the part that confuses me. He says its only GSM meaning T-mobile, ATT, etc. I thought that US998 was CDMA and GSM?
'''DEFINING FACTORS'''
The back of the phone displays a B&O (Edited, originally said B&W)
In software (in my settings) it says lg-us99820b
fastboot devies brings back
LGUS998c7507e2c
My firmware version is 8.0 may 2018
Will this model be eligible for WTF bootloader unlock?
Thank you all, just making sure to be extra careful so I can avoid a brick
Mate try IMEI info and use your imei to confirm your device model as long as its imei is not changed,also bootloader might also be the way of determining it but I don't recall bootloader's on LG displaying that info

It may say B&O (Bang & Olufsen, stereo manufacturer who helped tune the Quad DAC), but B&H Photo retail store sells carrier unlocked phones and they do NOT have their logos on the back panel. I have three genuine native US998 V30/V30+ bought from B&H Photo.
Whereas, B&O logo means it was not a genuine US998, nor is that back panel from a North American phone. LG does not have rights to sell B&O branded objects in North America. Another company has licensed those rights for North America. B&O branded LG V30 phones were sold in Asia. But don't worry, it's probably only the back panel.
There's some eBay refurbishers who are mixing and matching parts to create "like new" US998 phones.
Doesn't matter what it started as, as long as it's running US998 firmware. It's US998 now.

Most US998 being sold online nowadays are former LS998 -- especially if it's a 128GB V30+. That's OK. It's now carrier unlocked US998 V30+.
This means your mainboard is former LS998, and other parts (like back panel) are sourced from other V30 phones. They have already Frankensteined it for you to US998 firmware.

Yes, US998 has both CDMA and GSM/HSPA/LTE. But:
* Verizon won't let you activate a US998 as it's not a Verizon-branded phone. People get around that by having an already-activated Verizon SIM card or finding a Verizon rep who will bend the rules.
* Until last year (2019), Sprint would not activate a US998 on Sprint network, as it doesn't have 3 Sprint LTE bands. (Sprint finally changed their stance and allowed activation since mid-2019, but Sprint is going away. That brand will disappear in August, after being bought by T-mobile.)
So, anyone who bought a 2017 US998 in the U.S. could really only use it on AT&T or T-mobile or MVNOs using AT&T and T-mobile, while it was being manufactured. Unless you jumped through a lot of advanced hoops 99% of people don't even know exist. Dealers don't want returns or refunds -- so they play it safe by saying it's ONLY for AT&T or T-mobile.

Hmmm... Do you have 64GB internal memory or 128GB internal memory? Native AT&T H931 is only 64GB V30 while Sprint LS998 is 128GB V30+.
As I said, they've built this using parts from other phones. Looks like they have used part of LS998, part of H931 and back panel (B&O) of an Asia V30 to create this "US998". Still it's now a "US998" since it's successfully running US998 firmware.
You would use WTF bootloader unlock and root. It's already been converted to US998, so you have fastboot flash commands and it's already on pre-July 2028 early Oreo firmware, if what you reported is correct.

Wow Im stupid, yes it is B O Not BW. So I declared it was safe for flashing the new_unlock.bin via fastboot flash unlock command and for some reason am not getting a response. I can check if the phone is unlocked and it shows up on fastboot devices. I previously used the WTF method on my LG V30+ way back and loved the results, I just wanted to pass forward the joys of bootloader unlock and magisk to my girlfriend
Do you have any idea what I would do?
Does having OEM unlock on in developer settings make a difference?
Also I am in photomode for usb transfer as suggested.
EDIT:
also if I use fastboot oem device-id I get back
< waiting for device >
...
FAILED (command write failed (Too many links))
finished. total time: 0.004s
which is basically the same response I get when trying to flash unlock.bin
Also 64GB
Also Ive tried the exact same process on debian linux with no luck either

"Too many links" means ADB/fastboot is not communicating well with the phone. 11 of the 12 WTF Section 7 Trouble Shooting Tips are about the V30 ADB/fastboot communication issues.
Go check out WTF Section 7. Different port, different USB cable, different computer, etc. One person had to use 4 different computers...

Glad you got it working. Sorry it's not a 128GB V30+, but your girlfriend will still love the phone.
Flash to last Oreo 20h through TWRP flashable zips to get DTS Surround Sound stereo. You'll need to successively flash 20e, 20f, 20g, 20h all back-to-back in TWRP in one session (you can auto stack in TWRP) + Magisk, then reboot.
Later Oreo has much improved camera, plus DTS libs (but need root). However, you can't just jump to 20h with TWRP flashable zip, there's too many changes. So you have to incrementally update, but you can do it all in one TWRP session.

I totally will do that, thank you for the advice! Ill also do that for my 128 GB lg v30+ (my firmware has been buggy lately. Might be time to start from scratch again.) Do you know off hand what kdz id likely use as a preflash before updating?
Actually it appears that I did that process before as I am on US99820h. Is it safe to reflash only that one (20h) if my phone is already on the firmware or do I need to reflash to a preexisting fw and then update each?
Sorry for the late reply I went to sleep haha.
Btw you are awesome

If you are on US998 20h -- either by flashing 20h full image KDZ or you stacked 20e, 20f, 20g, 20h TWRP flashable zips and flashed those successively in TWRP -- then you can simply re-flash 20h TWRP flashable zip + Magisk to refresh the installation.
The latter Oreo TWRP-flashable zips have DTS Surround Sound build prop already enabled by the Dev (JohnFawkes). So even if you flash full image 20h KDZ, it's advantage to reflash the 20h TWRP flashable zip (+ Magisk). Otherwise you have to go make the build prop changes manually.
If you really want to refresh, you can factory reset just prior to flashing 20h TWRP flashable zip + Magisk. Just don't wipe internal memory,unless you have the zips backed up to microSD card or you can connect to PC while in TWRP to transfer them off.
I had previously changed my Sprint V30+ to the stock US998 Pie ROM and I am not rooted. I just received a notice from Cricket Wireless that my phone would no longer be allowed on their network after they shut off their 3G network in 2022. There is a list that shows the H931 (AT&T variant) will still work when this change happens so I am wondering if there is a ROM that I could flash that would change my phone to an H931?
Yes, the AT&T H931 TWRP-flashable zip. But you need unlocked bootloader and TWRP installed for that.
BUT if AT&T will only accept native H931 IMEI and not just firmware, you are out of luck. You probably got the notice because they can see your LS998 (Sprint) IMEI. My wife and my mother have native Open Market US998 on AT&T Prepaid (formerly called GoPhone) and they have recieved no such notice. Because AT&T knows they have the Open Market US998, not just US998 firmware flashed.
But you can try... You have a year to figure it out. AT&T's deadline is February 2022.
