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.

Depends on what you mean by undo it.
Not to pure stock AT&T, as AT&T doesn't release public KDZ. This is why non-AT&T people have to use Frankenstein to convert to another North American variant to carrier unlock it and receive updates with publicly available KDZ.
For people who are AT&T customers, they have to temporarily convert H931 to US998 for bootloader unlock and root. Then they can flash back to AT&T H931 firmware via TWRP-flashable zip (ROM) made by devs. So, you are back on AT&T H931 firmware -- but have TWRP custom recovery and root.
Tell us why you want to undo it and we can give better answer.
What was your reason to Frankenstein?
When I was using the device I did Frankenstein this device for the sole purpose of rooting and using custom roms. I moved to another device and have no real use for this device anymore. I wanted to sell it but as a pure att device. Which is why I was wondering if I could revert it back to where it was fully att stock, no root, no custom recovery nothing like that. Any help would be appreciated

No, you can't. AT&T doesn't release public KDZ.
But you can flash to full US998 Oreo KDZ via Refurbish mode in Dev Patched LGUP, relock the bootloader and sell on eBay as US998. Same way everyone sells converted Sprint LS998 as USS98. Same exact situation, as Sprint also doesn't release public KDZ.
Just curious here: If one were to flash the AT&T H931 firmware as TWRP flashable ZIP, then use LGUP in Partition DL mode to flash JUST the stock Recovery from US998 KDZ, wouldn't that be stock H931, or very close to it?
We could even have a TWRP flashable stock Recovery ZIP or IMG (which would of course overwrite TWRP).
If AT&T stock Recovery is somehow unique or different from US998 Recovery, I would think a TWRP flashable Recovery ZIP or IMG could be made of it, the same way the H931 ROM ZIP was made (I presume from an LGUP dump).
Again just asking, just curious, since this comes up from from time to time, usually when H931 owners want to sell their phones
Edit: Wait, I wasn't thinking straight: There's still the bootloader: If we flash back H931 stock Bootloader along with H931 stock Recovery, I suppose one could re-lock it. But not sure I would risk that, in case any other signed partitions are still US998 (not included in the H931 TWRP flashable ZIP) which might brick the phone once signature checking is enabled again.
So prolly just ignore this post. Too risky

One of the Sprint guys did that -- somehow they created a TWRP flashable zip which wipes out TWRP and restores Sprint LS998 back to Nougat upon reboot. It was created for warranty returns. If I remember correctly the bootloader is still unlocked but the warning doesn't show and Sprint rarely checks for such things.
However, that was for returning to carrier -- not selling. (If you are doing a warranty return and you are able to flash this zip, then it's nothing YOU did that firmware wise that messed up the phone -- something else is legitimately wrong with the phone. Like headset jack or whatever.) If you sell the phone with unlocked bootloader, the new owner can't use a lot of services without root or re-locking the bootloader (impossible without fastboot flash commands) and the Sprint LS998 is useless to them.
In my opinion, the better scenario is just selling as a carrier unlocked (but bootloader locked) full stock US998.

It does keep coming up but people should know the answer by now. The same reason you have to flash H931 or LS998 in the first place (carrier unlock, get updates) is the same reason you can't return to H931 or LS998.
That's not to say some dev can't create a "better" version of the Sprint LS998 zip for LS998 or similar one for AT&T H931, but it's not a high priority. People can still sell their phone. Former LS998 converted to US998 are sold every day on eBay.

I know, you made your recommendation about that clear in the past. And I don't necessarily disagree. But I also have understanding for those who want to be able to sell a plain "AT&H V30" to average users, who have no idea how to download KDZs or mess with LGUP in order to update their phones. Not everybody is like we are here.
It is of course a choice one makes when converting a H931 or LS998 to US998. But I think both viewpoints have validity, and I can certainly understand them both.
Edit: One comment on the many LS998 being sold as US998 nowadays is that I suspect most are being sold WITHOUT disclosing the fact that they are converted phones -- which I consider dishonest. If a H931 owner wants to sell their phone in an honest way, they have to either be upfront about the fact that it's converted to US998 (which is fine, and will be preferred by some buyers anyway) or find a way to convert it back to H931 -- which isn't confirmed possible at the moment, although the steps I mentioned might work if a user dares to try them.

I agree it should be disclosed.
In the past some converted LS998 were disclosed by dealers by calling it a "carrier unlocked LS998". Because the only way to carrier unlock an LS998 is to convert it to a carrier unlocked North American variant... In a way that's also dishonest, because then it can't be used on Sprint. Some Sprint users want the option of having a Sprint phone they can change to another carrier at some point in time. So, they would buy these "carrier unlocked" LS998 (which is truthful) but it wasn't disclosed they could now not use them on Sprint. (unless they bootloader unlocked, rooted, and flashed the return to warranty zip here on XDA).
It should be disclosed it's now a US998 but former H931 (which will be evident by the AT&T logo on the back panel, unless you replace it).

Maybe it was you I discussed this with but I'm more concerned about solving current owners' problems (people who have the phones in their hands right now) than people who will theoretically own the phone in 2 or 3 years. You can't live your live out of fear of what future owners will think about how you used your phone or what you did to it. It's YOUR phone right now, not theirs.
There never may be future owner! I never even sold my last two Moto Quarks. People nowadays often repurpose their older phones to be dashboard cams, security cameras, dedicated network streaming devices. Or they may give them to younger family members.

Oh I agree: Selling a converted LS998 (now US998) as an "unlocked LS998" is still dishonest salesmansspeak, when it can no longer be used on Sprint without first undergoing XDA assisted surgical procedures.
And yes, I think we discussed before about whether helping users prepare their phones for sale is a worthwhile effort. I think it absolutely is: That $150 towards a new phone is significant to many people (would be to me as well). Besides, it helps with warranty claims too, which also is important to many (to me as well).
But with everything you do here to help current owners' problems, I can definitely understand your priority: Fortunately you don't have to single-handedly do everything for everybody. It is perfectly OK for you to prioritize as you do. That doesn't eliminate the concern for those who do want or need to sell their phones. And of course to them it is a priority
I would be willing to help with the H931 effort if I can. I have an LGUP dump from a phone, and I may have my hands on a phone that I can tinker with too.
I agree with the idea of flashing-over the recovery would be a simple trick... just a question of how to get there. I'm no expert in these processes, but if I can help...
I will be unlocking my phone in about a month and moving to TMobile.
I'm just curious, has anyone moved their v30 plus from sprint to tmo and it work fine? (After unlocking it off course)
I do know there is one band that will not work, 600 or something like that, and I'm ok with that, as long as the rest will work ok.

Yes, many use on U.S. T-Mobile. Because the easiest way to carrier unlock LS998 is to flash US998 firmware. Convert LS998 V30+ to US99 V30+.
See the Frankenstein instructions.
At the end of the process you will have carrier unlocked US998 with 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
LTE band 71 is the only U.S. T-Mobile LTE band the US998 not any other V30 have except the T-Mobile H932.

Just carrier unlock.
Not wanting to root although I have rooted multiple other phones before, so I am comfortable with doing so if and when I decide to.
So that brings me to a couple other questions. I have looked over the Frankenstein thread on how to flash from ls998 to us998 and even have the files for lgup downloaded, but I was curious about a few things.
1: say if I flash and get on TMobile fine and everything works then for whatever reason I want to go back to sprint, will the us998 work on sprint or will I have to flash back to ls998 for it to work?
2: if it's needed to flash back to ls998, the only way I am reading on forums is to unlock the bootloader and root, unless there is another way without rooting that I missed? If there is a rootless way could anyone direct me to that, I'd appreciate it greatly.
Don't get me wrong, I'm in no way anti-root, it's just not for me with this phone, so I'm trying to do all this without rooting (if possible)

Both Sprint and AT&T do not release public KDZ (firmware images). For LS998, to carrier unlock it and get most compatibility with other North American carriers the method is to convert it (Frankenstein) to a native carrier unlocked firmware -- like Open Market US998 or even Canada H931. US998 is more popular because it also has fastboot flash commands.
While it's not entirely a one-way street, it's a lot harder to go back -- because Sprint doesn't release public KDZ images. Our talented devs have created their own TWRP flashable zips (basically ROMs) to flash back to Sprint firmware via TWRP. One dev even created a TWRP flashable zip for warranty return purposes that would flash back stock recovery, erasing TWRP custom recovery.
To use those, yes you have to be bootloader unlocked and have TWRP custom recovery.
While you can use US998 on Sprint, there are two caveats which may apply to you. Three Sprint LTE bands are missing on US998 and in the past Sprint wouldn't activate a US998 phone, even though IMEI shows it was a former LS998. However, someone recently said they were able to activate a NATIVE US998 phone on Sprint, so maybe their policies have changed? Still, in the past, the method for Sprint customers was to activate Sprint service while still on LS998 firmware, then temporarily convert to US998 for bootloader unlock and root, then flash back to Sprint firmware (to get those three LTE bands back) using TWRP flashable zip -- while keeping TWRP and root. If you wanted to go back to Sprint, you would probably have to bootloader unlock, install TWRP and flash one of those dev crafted Sprint stock ROMs.
I hope I haven't confused you. There is no need for you to bootloader unlock and root just to convert to US998 to go to T-mobile. "Frankenstein" existed long before our WTF bootloader unlock and root method, to carrier unlock the Sprint LS998 and AT&T H931. Merely convert to US998 and you are carrier unlocked, have bands compatible with most other carriers, and have access to publicly released KDZ.
The LS998 was the main reason Frankenstein was created. It's a V30+ and is available very inexpensively and can be carrier unlocked very easily. Most people using it are NOT Sprint customers. Like me, they bought to convert to US998. I wrote the Frankenstein instructions and the screenshot images are from my own LS998 I bought off eBay.

Awesome, thanks for the info, and no it didn't confuse me at all, I completely understand all of it.
On a side note I might add, that sprint and vz both detect the bootloader unlocked and will not currectly register with thier networks as long as the bootloader is unlocked.
I know this from experience, because I had a g5s plus that was rooted and worked fine on tmo, cricket, simple mobile, yet would not currectly setup and work right on sprint or on vz.
I tried flashing a stock rom and still did not work. Only when I locked the bl again did it then work fine on both networks. I got data but no calls or texts.
Since I had a very very very bad time locking the bl on that phone, and no one had a solution, it took me upwards of near 3 months to find a way to lock the bl.
Once I got the stock rom and locked the bl it works just fine with no issues at all.
I did find out from a friend that the way to have root on those networks is register it in the network THEN root it, although I was too lazy to do that so I just left it un-rooted.
That given, I just was wondering if there a simple way to relock the bootloader in case this may happen again in the future? Perhaps via fastboot commands??
As a side note, fastboot command did not work on my g5s plus sadly. It said it worked but when I rebooted nothing happened and bootloader was still unlocked. Not sure exactly why but as you can imagine it made me a bit gun shy on rooting. I've rooted a dozen or more phones in my span of phones, from the s2 and up, and the g5s plus is and was the only phone I had issues with and had a horrible time locking the bootloader.

Yes, bootloader is easily re-locked on US998 firmware.
Very good. Thanks so very much for all the info.
Hopefully it will just unlock via sprint and work on TMobile and I won't have to mess with anything but either way I'm ready.
Just FYI, thank you for your hard work and efforts on the tutorial on converting to us998. I greatly appreciate you and the devs and others that make it easier for us.
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.
