Mother board swap - LG V30 Questions & Answers

Hi,
I have a V30 (US998 128GB) fully rooted and LOVE it! Problem is I dropped it and now the screen flickers. A new screen cost approx $100 and then I would have to pay someone to install it since I'm not comfortable with screen replacement.
So I'm thinking about buying a cheaper used V30 like a locked H932 64GB or even one with a bad IMEI and just swapping out the motherboard with my current one. I assume that all other parts are exactly the same.
I am comfortable enough swapping the motherboard, its all the other tiny parts and the screen that scare me.
Can you think of any compatibility issues that may arise, or does this sound like a good plan?
Thanks in advance!

I believe H932 is a TMobile phone, which has slightly different hardware (due to the extra band) and different encryption as well. You could potentally do the swap with a better model (US998, VS996, H931, etc). That said I don't know if you'd want to take on a bad IMEI phone, because that would likely carry over with the motherboard? Unless you plan on resolving that in some other way.
Bottom line, I know US998, VS996, and H931 are the same hardware... I don't know about others.

Thanks. I plan on using my current US998 motherboard in the phone that I purchase. I believe I would be taking my own IMEI (embedded into my motherboard) into the new phone.
Which of the other hardware might me an issue, do you think?

Ahh, ok... I thought you were swapping the "new" MB into your phone. Duh... your plan makes more sense.
I would think it should all work fine, but just in case, I might limit your search to the phones I mentioned... but I agree, I expect the H932 would have the same frame/screen...
Mind you, this is based on ZERO experience on my part... just guessing since they are the same FCC ID and they are convertible to each other. YMMV!

UPDATE: For the benefit of anyone thinking of doing the same. It worked like a charm. Much easier and cheaper than a screen replacement.

How do I determine if my new Ebay-purchased LG G3 VS985 is truly factory unlocked?

My 21 month old VS985 crapped out 4 days ago. I believe it's an issue with the digitizer. The screen just stopped turning on altogether. When I tried it out again the next day, I discovered that sometimes when I let it sit for a while and cool down, I'll be able to turn the screen on for 10 - 60 seconds. After that, the screen freezes and slowly glitches/fades out. But it's only able to turn on sometimes. Sometimes the screen just won't do anything at all. That's the only thing wrong with it though, I've been able to use it with TeamViewer or by casting my screen to my TV.
(Any advice for replacing the digitizer will be very appreciated, even though that's not the point of this thread. Has anybody here done it? Is it necessary to remove the screen, or can I replace the entire screen/digitizer assembly? I tried to replace the broken screen of my Galaxy S3 a few years back and it was a complete disaster, because after I spent several minutes trying to heat up the glue with a hair-dryer and pry the screen off, I ended up just making the entire screen shatter much more into a billion little shards. All of which obviously destroyed the digitizer as well. Sigh.)
...
Anyway, none of that is the point of this thread. To replace the phone, I bought another LG G3 on ebay. It was listed a brand new, factory unlocked black 32GB VS985 for $175. The seller has 99.9% positive feedback (3 negative points out of 2,827) and the phone did indeed come sealed in the factory OEM box, with all of the accessories and everything. It's definitely brand new.
However, before I give the seller feedback, I want to make sure the phone is actually factory unlocked. Because if it's not, I will likely contact the seller and request a partial refund for a portion of my money on account of the item not being exactly as described.
The description of the listing says, "Brand New LG G3 Verizon 4G LTE Smartphone Factory Unlocked" and further down it also says, "ESN's Are Clear and Can Be Activated on Your Verizon Line, They Are Also GSM Unlocked to Use With AT&T, Cricket, Straight Talk, Metro Pcs, and More."
Now correct me if I'm wrong, but doesn't "factory unlocked" mean the device will work on all the major US carriers? Or does it mean it will only work on the carriers who share the same bands that are built into the LG G3? I don't know much about the technical side of this subject at all, so a little advice/correction would be really nice from you guys. It'll be a bit disappointing if the phone doesn't work with Sprint or T-Mobile, etc, but I'll live. I just want to make sure the seller described the item accurately before I leave him (otherwise well-deserved) positive feedback.
Thanks for reading!

Sounds fishy to me. As far as I know, the VS985 is Verizon only. But, I could be wrong. Just not sure it's a legit offer. But that's just my personal opinion. Someone might have a more educated answer on this, but for me, I would have avoided it.

All Verizon devices are factory unlocked as is. You can freely use any made-for-Verizon device on any carrier that the device's radio frequencies support. Unfortunately, the VS985 only supports a few other frequencies, some of which do require enabling on your own in order to use - and that's not the same kind thing as being "factory unlocked", but Verizon themselves do not restrict the device from being used on any carrier, and some other devices like my VK810 support even fewer radio frequencies than the VS985 making it harder to use with any other network, but not impossible.
Bunches of people in these sections have made posts about using their VS985 on other networks, which besides enabling particular radio bands that the VS985 supports, sometimes only requires changing the APN (and the SIM obviously). The software does complain when a Verizon SIM isn't installed, but it's just an annoyance and doesn't keep from using the phone that way, and there may be ways to disable that (G3TweaksBox?).
I can't answer particulars because I've never used mine on anything but Verizon.
IMHO, the title of the Ebay listing is only misleading because all VS985s are factory unlocked; i.e. the particular listing isn't special by specifically mentioning that it's unlocked, but it's not inferior because of it either.
To be clear, "it will only work on the carriers who share the same bands that are built into the LG G3." There's no possibility that a device could work with carriers that use bands other than what the device supports, and being factory unlocked doesn't mean that you don't have to follow the instructions in the threads having to do with enabling optional bands if you wanted to use it on certain carriers, since the stock LG ROMs have some of those optional bands disabled by default. *Some* bands other than what Verizon uses are already enabled.
That is interesting about being able to enable some additional radio bands. I am waiting for a VS985 which I just bought, in order to try it with Total Wireless, since the AT&T coverage in my area comes up short for data connection. Am hoping that it will also work well enough with AT&T if I have a poor result with TW.
A few years back, while living in a different area, I had pretty good results with a G2 vs980 as GSM with t-mo, although results were a little better after switching to the t-mo G2 D801, so I figured that it would serve for AT&T as well if need be, although I've read reports of it lacking LTE band for AT&T, but they don't seem to offer LTE in my area anyway, so no loss there.

Few questions before buying

My LG G2 just died and I'm looking for a replacement. LG V30 (EU version) looks pretty good, but I have a few questions.
Just like with my G2 I would have to get rid of LG software and flash lineage but that means no lg "features" and here lies the question.
Is there anything gamechanging I would lose?
From what I've read the quad DAC doesn't work but I dont have any audiophile grade headphones so regular snapdragon DAC should get the job done just fine, but what about the camera.
The main reason I'm looking into this phone is the camera, waterproofing and heaphone jack (S8 has also these features but lineage is broken on that thing and I won't touch touchwiz).
So how is the camera on non stock roms? Do I still have acces to the wide angle one and other goodies?
If there is anything else I'm missing please let me know.
You can install both GCam builds one for the main camera and one for the wide angle camera, so you have 2 different apps for each back camera.
As for the quad dac - you can use it:
https://forum.xda-developers.com/showpost.php?p=77389334&postcount=15
Onkyo HF Player
USB Audio Player PRO
both are able to utilize the quad dac,
with the 2nd you can even use it with streaming

not entirely sure about qnovo but it's an in-kernel driver so it also seems to be used on ROMs different from LG's Stock ROM

Thanks. I'm pleasently surprised by that DAC. Thought I would have to give that up for sure.
2 apps for camera is annoying but as long as it takes good photos it doesn't really matter. Is the camera still good on aosp roms?
I know people usually praise Gcam and from reviews this phone has good camera but I figured I might as well ask.
Anything else I should know? I know the speaker is not the best but after the G2 speaker anything is going to be great

Some LS998 V30+questions
Stormwing said:
I've been looking for a modern, rootable, and bootloader unlockable replacement for my rather aged phone (Sony Xperia Z3v) and after realizing the S8 is horribly locked down my search has led me to your extensive body of experience and research involving the LS998 V30+, to a point where I'm pretty sure it's the one. But because I've fallen off the development wagon for so long I hope you won't mind if I ask you a couple things since you are the resident expert:
Given it's a Sprint device, the LS998 should be fine on Verizon, correct? And should be okay overseas as well?
I haven't really ROM'd since the Gingerbread/ICS days on my old Droids, will this be able to offer a similarly open experience?
Is the $315 eBay one a reliable buy? No issues with the screen (burn in, graying) or condition?
eBay's running one of their sitewide 15% off sales today (PREGAME15) and I'm thinking about pulling the trigger.
Thanks for your time!

This same dealer also has MINT US998 V30+ for $310 right now. Not sure why it's less than the LS998, but not only is it $5 cheaper but with the 15% discount, that makes it less than $264.... I fully expect it's probably already a converted LS998, but that still saves you one step in bootloader unlock and rooting..
BACK TO YOUR QUESTION.
YES, pull the trigger -- on either.
For the LS998 V30+ $315 - 15% = less than $268 for MINT LS998 V30+. I've bought two LS998 from this dealer -- gave one to my sister, gave the other to my wife (both converted to US998).
Just make sure you ONLY stick to the "mint" for sale (9/10) from this dealer. Don't buy the "good", "very good" -- ONLY MINT.
Yes, the "LS998" will work on Verizon, but not as you buy it. As you easily modify it, with Frankenstein. You'll convert the LS998 first to US998 to sim card unlock/network unlock and make it Verizon-compatible -- with all proper CDMA and LTE bands, blah, blah, blah. At this point you could use it on Verizon since you now have a carrier unlocked US998 V30+, meant to be used on all North American carriers.
http://www.lg.com/us/cell-phones/lg-US998-Unlocked-v30
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
ANY North American V30 variant (AT&T H931, Verizon VS996, Sprint LS998, carrier unlocked US998, Canadian H933, regional AS998) can be converted to any other North American V30 variant (except for T-mobile H932) with dev patched LGUP (a.k.a. Frankenstein) The only reason the Sprint LS998 seems more popular is for some reason it was ridiculously cheap on eBay as no one wanted carrier locked down Sprint phones. The Verizon, AT&T, even carrier unlocked US998 were going for $200 more. Then, we found out you could CONVERT the LS998 V30+ to any other North American V30+ and carrier unlock it in the process. Woo hoo! This then reached epic proportions when you add bootloader unlock and root to the mix.
OR you could convert straight to Verizon VS996 from LS998 -- and make it be a Verizon V30+ (which Verizon doesn't actually sell, they only sell the V30). However, let's not confuse you and let's say you convert eBay LS998 V30+ to US998 V30+ for right now...
But wait, there's more! NOW that you have US998, this means you also have fastboot flash commands. You have also converted to an US998 Oreo KDZ with wonderful bootloader unlock exploit. So, at this point we now go on to the WTF bootloader unlock and root. You unlock bootloader, install TWRP, and root.
OK, you started with an LS998 V30+. You converted to US998 V30+ to carrier unlock the phone AND get fastboot flash commands. You've now unlocked the bootloader, installed TWRP and rooted the phone. 30 minutes have gone by. What are you going to do with the rest of the day?
Well... here's where it gets interesting. AT THIS POINT, you can call it a day, stick in your Verizon SIM card and be happy. OR you can flash the VS996 TWRP-flashable stock "ROM" @westwood24 made for us (basically the latest Verizon update as a TWRP flashable zip file, but with TWRP custom recovery). Now you have Verizon firmware and modem on your phone -- but still have TWRP and root.
(Sprint users feeling left out, yes there's ways to flash back to Sprint firmware. Or you can go flash custom ROMs and just use Sprint APNs and modem.)
Back to @Stormwing's question. You can even flash custom ROMs, if you wish.
Other Verizon users can chime in at this point if they want, to give you suggestions.
Wow @ChazzMatt, thanks for that incredibly thorough rundown! Is there risk in going for that $310 perhaps-preconverted 'US998' model? It does seem a little fishy as it's cheaper yet possibly better, and if the difference is just $5 I'm inclined to go for your tried and tested LS998.
All I want is a reliable handset that works on Big Red and can flash ROMs and I'll be a very happy camper. It's been too long since I've had an unlocked bootloader.

The only "drawback" I can think of is if this US998 already has 20D. Then you'd have temporarily flash 20A or 20B to get back to Oreo with bootloader unlock exploit. But you would have to flash that any way with LS998 (first to US998 Nougat, then US998 Oreo 20A or 20B).
So, you're still saving a step.
My brother in law just ordered this US998 V30+ yesterday, before the 15% sale code. I can't tell him, he'll be mad. But he dunked his old phone in water and needs a new phone fast. He's not into rooting and stuff, he just wants a good phone. And this one is IP68.
wow..I just happened to stumble onto this thread while searching on V30+. Just bought one w/ the 15% off. Thank you sir!!
Ok good to know, thanks. Unfortunately I ran into some technical difficulties with PayPal and ended up missing it. Guess I'll be joining you guys the next time one of these promos roll around....
I have just 2 things to say, 1) the selfie camera's quality is quite embarrassing, Gcam makes it better but you have to choose the longer shutter option and stay still for 3 seconds
2) Check the screen on low brightness for any inconsistencies of the notorious P-OLED

No one is going to defend the selfie cam in the V30. Oreo did make it better. (On Nougat you had to turn off the skin enhancement setting.)
Since I don't use my phone display at very low brightness, that's not an issue for me. You lose vibrancy and colors of OLED displays at low brightness. I've owned five of these phones (gave two to relatives) and know five more relatives/friends who bought for themselves. We all keep the displays at normal brightness, so the topic has never come up. For me "normal" is anything over 50%. I keep mine on 70%.

10 means Nougat
20 is Oreo
You are half way through Frankenstein. You still need to upgrade to "safe" Oreo.
And d means the exploit is patched then? sorry newbish on these phones I am.

No. The letter is just the software version. B comes before C. Etc.
But US998 20D has the July 2018 security patch that blocks the bootloader unlock exploit where we don't need LG's permission.
For Europe it's 20Y.
You can look at the date in the file name and roughly tell which update has (most of time). Any with July and later, stay away from. I can think of one H930DS model where an early July update still had June security patch, but that's the rare exception.
Any July 2018 or later, stay away from until bootloader unlock. If you get one like that, you can still temporarily downgrade to unlock bootloader. Just don't install on purpose until she after you unlock the bootloader or you're making extra work for yourself for no reason.
Heads up everyone: eBay is doing a Labor Day promo for 20% off with the code JUSTRELAX
I'm an idiot. It's restricted to certain sellers only again.
HOWEVER the seller has raised the prices in anticipation and the aforementioned LS998 is now $288 after the code, but the US998 is happily still at $264 after the code. @christoophat, were you able to return yours though? And @ChazzMatt, besides the screen, how was the condition of the your brother's phone?

The seller was a bit hard to get hold of, took 3 emails thru ebay to finally get him to respond, to offer to get it returned for a replacement. Hopefully the return gets processed soon & he still has an actuall 9/10 phone left to exchange it with. Where do you find out about the ebay sales? I never get any emails from ebay about them...

Hmmm I wonder if I should give it a shot then. I only found out about the last one via The Verge and I found this one by looking up eBay on Slickdeals. I actually set up a Slickdeals account and added an eBay alert but that didn't seem to do anything.

I'm wondering if, during these sales, that ebay covers the balance for the sellers that's taken off during them. My invoice shows the full price ($309), but I only paid $263.
And yes, I noticed that the average prices for V30s have spiked up a bit. 20% off is a sweet deal. Also found a killer Tech21 Evo Check case for $8.

Unroot/re-lock of H931 converted to US998

Hi all - long time lurker, first time poster. Big thanks to this community for helping me with random roots throughout the years, but I've come across something I can't quite find definitive answers on and need some assistance.
A few months ago I finally took the plunge and unlocked/rooted my AT&T h931. This was by far the most complicated root I've ever done, but I got it done. As most know, this requires first converting my h931 to a carrier unlocked US998, and then proceeding as usual. I followed this amazing thread on Reddit that someone put together based on a bunch of different threads here on XDA.
So I've now decided I want to buy a 1+7 Pro and want to take advantage of their trade-in program, so I'd like to get the phone back to stock and unroot/relock it all up. I found a solid thread here but because of my special circumstances I'm concerned there will be a bit more to it. The phone has the AT&T logo on the back, so if 1+ gets it and it's an unlocked 998, I'm not sure they'd give me and money for it. Without getting too into the weeds, I just want to know if anyone has advice or can point me to a post detailing this specific circumstance. Do I need to re-convert to a h931 before relocking? If I go back to stock/relock as a 998, will AT&T still work alright? I just don't want to mess something up and brick my phone.
Any insight is greatly appreciated. Thanks everyone!
To my understanding, AT&T doesn't share KDZs anywhere, so I don't think it's possible to convert your phone back to H931. I could be wrong.
Otherwise the general steps would be:
1) Revert to stock by flashing US998 KDZ with LGUP in refurbish mode. Phone must be completely stock before relocking the bootloader.
2) Boot into fastboot mode and relock bootloader with fastboot oem lock.
3) Flash the carrier firmware KDZ with LGUP in refurbish mode. Again, in the case of AT&T I don't think it exists.
The reason for this sequence is that the carrier firmware may not allow fastboot.
Edit: Oh, of course if H932 users should see this: Do NOT ever flash the US998 KDZ. Just flash the latest H932 KDZ and use that to relock the bootloader.
AT&T doesn't release KDZ... you can't go back to stock...

Right. But a mint US998 can be sold on eBay for $160-$170 right now...

Interesting. I recognize my own words throughout most of it, of course -- with same emphasis I use.
Update H931 (AT&T) to Android Pie! (Walkthrough)
This is just the "bootloader unlock warning" screen. It's just a scary picture LG shows you as the phone boots to discourage you from unlocking your bootloader. Ignore it. It will NOT prevent you from doing anything.

I see they got a "Platinum" award on Reddit?
Well, at least they gave me credit! They combined my Frankenstein and WTF instructions, but focused on H931 and stripped out all the stuff that applied to other V30 variants. (Which is why WTF is like a decision tree -- if you have this variant do X, if you have that variant do Y -- until in Section 5 everyone ends up at the same bootloader unlock "starting line" with fastboot flash commands and early Oreo firmware.)
Everything is cool. They gave me credit and asked people to hit thanks button several times for me here on XDA in return. :good:
_______
However, the rest of their walkthrough is about custom ROMs, and they credited two other worthy people for that section.
In neither Frankenstein nor WTF, I do not really mention custom ROMs. Because that's not the purpose of either thread.
Frankenstein is to convert your phone to another North American V30 variants -- either to carrier unlock your phone or to instill fastboot flash commands, or both.
For WTF -- it's to unlock your V30 bootloader, install TWRP and get you rooted. (So, some phones like H931 need to take a side trip to Frankenstein thread, but other phones like H930 or H930DS don't need that, as they already have fastboot flash commands.)
Only in the Root Sticky I wrote, I warn H931/H933 takes "extra prep work" for custom ROMs and that all phones should be updated back to latest stock firmware prior to installing custom ROMs. If they have H931/H933, I leave it to them to find out more, as I don't want to scare them off.
Someone once mentioned doing something like this guy did on Reddit thread for ALL V30 variants -- one bootloader unlock/root thread for each variant. US998, H931, H933, LS998, VS996, H930, H930D, H930G, H930DS, AS998, H932 (both T-mobile and Puerto Rico), and that's not even mentioning the Korean variants! But that would be severe overkill and a lot of redundancy. The way WTF is designed, it can handle EVERY V30 on the planet (except for T-mobile H932), as long as you follow decision tree choices. There is a separate thread for T-mobile H932, because it's separate procedure involving a Linux boot disc and other stuff.
___
Oh, to the last guy asking questions in that Reddit thread? (duplicate questions) Tell him in Frankenstein conversion, he either didn't do a Master Reset after flashing to Nougat (not following all the steps) or he mistakenly flashed Oreo US998 first, probably thinking they didn't need to flash Nougat (not following all the steps). That's why his phone is bootlooping.

Thanks for all your hard work on this stuff ChazzMatt! This guy simply streamlined all the work you did specifically for the H931 variant, which was what I needed.
Thanks for the heads up about selling the US998 on Ebay... I hadn't really considered that, but will definitely look deeper into it now. So I could basically just flash a stock image for the US998 and call it good, yeah? Do most interested parties on Ebay prefer these phones remain rooted/unlocked in your (or anyone's) experience?
Thanks for your input all.

Vast majority prefer carrier unlocked phones, not necessary bootloader unlocked and rooted. With the scary bootloader unlock warning about "possible corruption" just best to re- lock bootloader before selling it.
Flash to US998 20H, then relock bootloader.

And that is exactly correct. It won't get updates as a 998 nor as a used-to-be 931. While yes, of course, some people will understand that and know how to apply an update, **THE VAST MAJORITY** of buyers WILL NOT.
Given that limitation, be sure you state that specifically when selling it. As Dinou says, ebay will be on yer butt otherwise.

No they won't report the seller.
None of the LS998 to US998 sold on eBay all the time get OTA updates.
All the US998 V30+ being sold by dealers are former LS998.
No one is reported. The dealer has 99.9 approval rating.
That's the only way to carrier unlock an LS998. I bought one US998 new in box from Wal-Mart, and it's former LS998 converted to US998.
Same with H931.
And it's the only way you're going to be able to sell it. I mean, you can convert to VS996 or H933, but same thing. US998 is the best choice.

If you want to sell it on eBay you have to explain that the phone is really a H931 running US998 firmware. If not, the buyer can just return the phone for a full refund after he finds out the phone isn't a US998 which will be easy since H931 has a AT&T logo.
You'd have to pay for the return shipping, eat the original shipping cost, and still have to pay eBay fees...

Like I've said... if the buyer finds out that the phone is not a real US998 and wants to return it then the seller has to cover return shipping and issue a full refund.
If not, the buyer can file a dispute stating item not as described and the seller will be forced to take it back...
The simplest answer to all this is of course simple: be honest in the ad, list every piece of relevant information and that way if there's any kind of claim for any reason other than "It's dead on arrival, Jim..." protects you (or whoever) as the seller.
It can't be stressed enough really to put ALL the relevant info in the ad, be 100% honest about everything:
- be honest that's its originally an AT&T H931
- be honest that the bootloader was unlocked and that message will appear each time the device is powered on from a cold start
- be honest that it has a clean IMEI with no leins/not reported stolen/not reported lost (but don't provide the IMEI directly, that can be provided in a PM if necessary using eBay's message system if a potential buyer wants it)
- be honest that it was converted to becoming a US Cellular US998 in every respect except for it being a true US998 hardware-wise
- be honest that it will not get OTA updates for future releases of Android (if they'd come out) and might not get security fixes or patches either because of that conversion
- be honest and say the condition and mention every single scratch or scuff or mark on it, take plenty of decent pics, show the Settings page, etc
- be honest about what's included
- be honest and just flat out say "If you decide to make this purchase, you do so understanding everything that's been stated in this ad and accept this prior to the purchase, after which there will be no refunds except for the item being literally DOA and non-functional" or words to that effect and clearly state "SOLD AS-IS" in the ad listing at least once and not buried someplace a the very bottom or whatever
If you don't do anything that can be perceived as being deceptive then eBay (and whatever payment processing service you use) will more than likely side with you, the seller, should an issue arise - if it's truly DOA for whatever reason you're going to have to issue a refund regardless, but I don't think that most people would damage or break something intentionally just to get that refund. This basic idea of being honest about it to as many degrees as you possibly can ensures that you'll only be selling to someone that really understands what it is and if they don't, your listing told them ahead of time so that responsibility is now not on you for them being ignorant.
You can't really do much more than this, so either get to it and sell it on eBay with these kinds of guidelines or keep it and maybe sell it locally, either way, good luck.

Flashing the stock h931 rom will get you close but the BL will still be unlocked(but there is no message on bootup). It has the stock att boot animation.
Notes:
It wipes your internal storage when flashing.
OTA will no longer work.

The AT&T H931 does not have a CDMA radio in it, neither does the H933 (the Rogers Wireless aka Canadian version) so no, they're not the same as the actual US998 hardware which does have both CDMA and GSM radios in it. As my sig clearly states, I have an H931 converted to a US998 and I can't use it with Sprint or Verizon since it doesn't have a CDMA radio in it so, no, they're not all the exact same hardware.
The VS996 is designed to work with Verizon which is a CDMA carrier so that one does have a CDMA radio in it but it offers slightly different LTE band coverage (some of the other bands for AT&T and T-Mobile are covered as roaming bands).
Each model has something different from the others based on what the carriers tell LG to do with them at the factory, which is why I said what I said.
The T-Mobile LG V30 H932 is the only one that has hardware support for LTE band 71 too so, again, something different for every model.
You can't go wrong with being honest -- except you may not get the sale on eBay, where dozens other V30s are listed as New or Mint, even though we all know they're Frankenphones. Those sellers are probably willing to absorb a few returns because they bought them by the truckload for $30 each.
Why not just just flash US998 KDZ and relock the bootloader, then see if OnePlus will accept the trade-in? That's what you wanted originally, right?
They're looking for a sale, so they're motivated. And if they DON'T accept the trade-in, then you can worry about selling it on eBay.
That's really what I assumed would be your takeaway from my original reply (post #2).

You DO have CDMA radio if you converted your H931 to US998. You can't use it on Sprint and Verizon because neither will take an H931 -- NOT because your NOW-US998 doesn't have CDMA.
Sprint won't even take US998 as they only take their own branded LS998 (which is why you have to activate LS998 on Sprint BEFORE Frankenstein, bootloader unlock and root).
Verizon conversely looks only at IMEI, and they see it as H931 even if it's now US998 with CDMA. Be interesting to see what happens when Verizon DROPS CDMA end of this year!

It was converted to Open Market US998. DON'T call it "U.S. Cellular" US998. It's NOT. Many U.S. Cellular phones are carrier locked, and U.S. Cellular only takes phones they sell -- so if a U.S. Cellular customer bought it they would be disappointed.
NO, the bootloader unlock warning will not appear because he's going to lock it back.
Yes, clearly state no refunds.

Thank you for bringing some clarity to the discussion.
Yes, relock the bootloader and try the trade in. OnePlus isn't going to look at it that carefully, except to verify it's working. They're immediately going to turn around and WHOLESALE to an eBay dealer -- WHO WILL SELL IT ON EBAY.
The eBay dealer will probably swap out the back panel to get rid of the AT&T logo. It'll be sold as US998, which is what it is.

Verizon activation help

Hey everyone,
So I did this on my personal phones a few years ago, and even my MIL's phone (Mother in law). I cut the SIM card in those cases, and plugged it into the new phone, and all worked just fine for the most part (MIL phone is having issues, maybe because I did a poor job of the manual cutting).
Anyway, now I'm on the FIL's phone (father in law). I activated a brand new phone on an old Droid Turbo phone, and it's working fine there. I moved the SIM to the new V30 (originally US998) and it's not registering on the network. I wonder if I just did this too quickly (I didn't let the SIM "sit" on the Turbo for very long)... which is why I moved it back there now. I figure I should let it sit there for a bit, and then try again?
Any ideas on what else I can try? Basically, the V30 was saying it saw the phone number, but it said IMS not registered... any ideas on how we can fix that? The *#*#4636#*#* doesn't work on the LG phones... I've used Shortcut Master before to register VOLTE, but I'm out of my realm here because the SIM is not registering the phone, so that's not an APN or VOLTE issue.
Any help or ideas are appreciated... thank you!
EDIT: One more comment. I'm hoping to go to VZ tomorrow and get a new card for the MIL phone. In order to activate that SIM, I'll have to activate that SIM on the Turbo, otherwise VZ will throw a hissyfit for the mismatched IMEI. So, I'm hoping I can repeat this process with the new SIM on that phone... I'm hoping we don't have this problem there too.
Ugh, VZ, why do you suck so bad.
I've been down a similar path. I own the same phones. You didn't mention which rom is on the v30 but suspect it is a us998. I, too, had some difficulties getting my v30 to work properly on the vz network. The turbo with a stock verizon rom came in handy to set vz account/network options.
1) Install stock MM rom on the turbo. The debloated one by computer_freak works great. You can get it here: https://forum.xda-developers.com/dr.../computerfreek274mm1-0-android-6-0-1-t3503634
2) Pop the vz sim in the turbo
3) Activate: HD calling, visual voicemail in the dialer, and set up volte. I don't remember if vowifi is an option on the turbo. If it is, then turn it on, too.
4) Put sim in the v30 and enjoy.
Another and possibly better option to get the sim and phone working together is to cross-flash to the verizon vs996 rom. The advantage of the vs996 rom is that vowifi and visual voicemail will work. I've never succeeded in getting vowifi provisioned on the us998 open market rom. That is some vz-lg shennanigan.
I second what cmrntnnr stated above and emphasize flashing VS996 on the V30. Big Red can still tell what your phone actually is by its IMEI. My V30 originally was a LS998. I also had to manually set the MMS settings to keep Verizon firmware from thinking it is a Sprint phone. Please see this if you have issues with MMS. https://forum.xda-developers.com/lg-v30/how-to/guide-how-fixed-mms-settings-flashable-t3856109
Yes, I am on VS996 for this phone. And I did this very same process on my personal phones, but for some reason the new V30 isn't accepting the card, which is why I asked.
Yes, I know VZ can see it's not a true VS996. Thanks for the link to fix MMS, but I wanted to fix the lack of connection first before working on the other things.
I will try it again (maybe I swapped SIMs "too fast" for the VZ network to accept it or something?... though I swapped it back to the FIL's LG G3 with no issues... so very weird, and annoying).
All that said, we may just get them "true" VS996s instead, because that way they can still get help from VZ when they aren't nearby (they live in FL, while I'm in CT). It's not that VZ can't help, it's just that they won't... that's what pisses me off...
EDIT: Again, the question is, why isn't this phone connecting? It's seeing the phone number, sees the SIM fine, just wouldn't connect to the network and kept saying it wasn't registered... didn't know if there was a trick I could do or something to force it (probably not, as it may be a VZ-server thing, but who knows).

Awesome, this is what I was looking for.
I tried getting to the secret menu, but it never seems to work (even on stock dialer). When I did the VOLTE fix on my phone, I had to use ShortcutMaster.
Regardless, once there, what should I look for/do?
I have the phone back in-hand now. As before, the SIM works fine in the old phone (LG G3) but it still doesn't connect with the new V30 (on VS996). Note, I did use a SIM adapter to put it into the old phone (it uses micro-SIM sized cards). And, again, it's seeing the correct phone number, but it's not connecting to the network. Network mode is set to global (default) and toggling that around doesn't help.
I also got ShortcutMasterLite to let me into the 4636 menu, but I don't see anything wrong in there either. Not sure how to get this phone working?!
I'm now wondering if it's just a defective phone? I'm seeing signal levels that match my other phone, but still, who knows? Maybe the radio is having issues or something... I suppose I could try my personal SIM instead, or something?
So no help.... not that I'm blaming anyone.
Problem is that the Ebay listing said that this phone will NOT work on VZ, etc. So, I don't have much hope of the seller helping me, even though it's a completely false statement, as we all know. So, I may have to convert back to US998 and then test with an ATT SIM to prove to the seller that this is a defective phone. Anyone have any ideas on how I could do this? For example, would anyone be willing to meet me somewhere (I live in CT, but I can drive wherever in New England) to try your SIM on this phone? I figure, if it doesn't work, then I have proof that it's defective. Otherwise, I don't think the seller is going to even try to help.
Anyone willing to throw me a bone here with a little help? Or anyone have other ideas on how I can test? Does ATT have a prepaid thing that I could try for a month (low cost) to prove it out or something? I know far too little about ATT...

Yes.
They have a Prepaid minutes plan they don't like to advertise.
https://www.att.com/buy/wireless/prepaid/devicesandplans
When you put in your IMEI to the AT&T Prepaid webpage put all zeroes instead of your real IMEI and it will show you all plans, not just what they want to sell you.
Also AT&T Prepaid uses same same regular AT&T SIM cards. Don't let them sell you some special SIM card.
I'd have reached out to help if I had any ideas. Your hypothesis that it is broken seems reasonable and so does flashing it to US998 as verification.
Getting on the ATT network without ATT is a breeze. Cruise down to Walmart and pick up a StraightTalk kit for $30-50. It will have sims for VZ, ATT, and TM so you can choose whichever network is best for you. They're good to have around.

Hey everyone,
So I did this on my personal phones a few years ago, and even my MIL's phone (Mother in law). I cut the SIM card in those cases, and plugged it into the new phone, and all worked just fine for the most part (MIL phone is having issues, maybe because I did a poor job of the manual cutting).
Anyway, now I'm on the FIL's phone (father in law). I activated a brand new phone on an old Droid Turbo phone, and it's working fine there. I moved the SIM to the new V30 (originally US998) and it's not registering on the network. I wonder if I just did this too quickly (I didn't let the SIM "sit" on the Turbo for very long)... which is why I moved it back there now. I figure I should let it sit there for a bit, and then try again?
Any ideas on what else I can try? Basically, the V30 was saying it saw the phone number, but it said IMS not registered... any ideas on how we can fix that? The *#*#4636#*#* doesn't work on the LG phones... I've used Shortcut Master before to register VOLTE, but I'm out of my realm here because the SIM is not registering the phone, so that's not an APN or VOLTE issue.
Any help or ideas are appreciated... thank you!
EDIT: One more comment. I'm hoping to go to VZ tomorrow and get a new card for the MIL phone. In order to activate that SIM, I'll have to activate that SIM on the Turbo, otherwise VZ will throw a hissyfit for the mismatched IMEI. So, I'm hoping I can repeat this process with the new SIM on that phone... I'm hoping we don't have this problem there too.
Ugh, VZ, why do you suck so bad.

Which VS996 version did you flash? Nougat, Oreo, Pie? Try Nougat as it's the most reliable VS996. US998 Nougat should read VZW sim also.
Thanks for the tips on ATT and Straight Talk. I think I will have to try that, but first I'm going to try to get the ebay seller to "promise" me that if I go through this, that they'll actually do something to help. Otherwise I'm just spending money for no reason.
As for the VS996, it was Oreo, the same version I'm using on my personal phones, and the other V30 - you may recall that the MIL's phone is functioning, but the FIL's is the one that is just not connecting at all... I always get 0-bars with the "x" on that one. That's what I'm trying to fix here...
Again, thanks for the tips, let's see what I can get done here with all your excellent help!
Ok, so the debacle is over. I wanted to provide a little info for what ended up happening, and what I learned.
Longer story short, I was able to get the first H931 phone working fine with no issues. It runs on VZ towers on VS996 and US998 (I created a video for the latter, to prove it to myself and the warranty company). The second one refused to work on VZ, and I felt it had issues on GSM carriers as well (I tested Mint Mobile, as it was free). This phone was sent for repair to a warranty company that the ebay seller offered to pay for.
The warranty company tried to get that phone to work on VZ, but couldn't. They kept telling me that this was "not possible" when, as we all know, it most certainly is. Bottom line, something is defective with that phone, as I suspected. However, I expect no one is going to bother to repair it so it will likely show up on Ebay or wherever again as an H931 (or US998) with this problem persisting. I figure another buyer may not notice it, as long as they don't use VZ....
But, the moral here is that you should be careful when you buy the device, to ensure that the seller doesn't put text on their post saying that it won't work on other carriers. I was afraid of this text, but I went forward anyway as I (and we) know this works fine. I also proved it on one phone (the first one). However, if the seller says this, then they won't necessarily take any steps to help fix the issue if there is a problem anyway. I got lucky and my seller at least provided me with the warranty card, which helped a lot.
The warranty company did do everything they could to help. I have to commend them on that, as we are hacking the phone, after all... but Jose was very understanding and helpful regardless. For this reason, I really recommend their service... they are CPS Warranty and they can be found at https://www.cpscentral.com/ Again, they could have blown me off, but they didn't... and after all that, they offered a settlement to pay be back for the phone since they couldn't get it working on VZ. I'm out a little money, but the settlement was fair, so I can't complain.
So, while this all works, we do need to be careful, as some devices are defective and hard to detect for this type of issue.

How to get back V30S black & white boot screen after frankenstein?

I picked up a V30S and now I have rooted it successfully. However, during the conversion from US998h to VS996k in TWRP, I lost the "S" part in the boot, and now it just says "LG V30 thinq" whereas it used to say "LG V30 thinq", like the attached picture.
I would like to get that back. I liked seeing the "S" part when it boots up, it feels more premium.
The same thing happened with my V30+, it lost the "+" once changing to VS996.
How can I get this original factory boot screen back?

You can't get that back on Verizon firmware. Verizon didn't sell the V30+ nor V30S, only the V30.
You can get original factory boot screen back by flashing back to US998 firmware.
Which is what you'll do when you sell it eventually, but until then it doesn't really matter.

If you could do that, people could claim to have V30+ who don't...
Good luck with that. Don't brick your phone.
I already know you can edit the other boot, so by the way I already know it is possible to put a boot screen of anything, after the initial boot screen, so your argument is pointless.
As far as tricking someone, anyone can look up the IMEI to find the true model of the phone. Also, you can look at the storage. If you put a "plus" on a 64gb non-plus that would be STUPID since both phones cost nearly the same.
Looking for someone to actually help. I do have the actual phone and I could show my IMEI to prove it. I bought this second phone for the 6GB of ram (I now have a V30 Plus AND a V30S). I looked for months to find one. Part of why I'd like to see the S in the boot screen since I put a lot of effort into finding this phone. I have no intentions of ever selling it. It's the perfect phone for me and I could see keeping it for many years.

Yes, the V30/30+/v30S are fantastic phones. Congratulations on finding a V30S. A year ago when I was looking they were still too expensive and already have several V30/V30+.
I wasn't talking about YOU tricking someone, I was just talking about in general. Someone recently posted they want to do that, so people would think they v30+ when they only had V30. Don't know why, they weren't talking about cheating someone, they were talking about just bragging about it.
Lots of people have asked what you have, nobody's been able to do it.
Same thing with getting rid of the bootloader unlocked warning. The only way you can that is to do is what you did -- flash Verizon firmware. OR flash partial Verizon firmware -- which is dangerous for other variants because every time you update your firmware, if you don't match compatible firmware you brick your phone.
Good luck in your quest.

Yes, it (V30S) was hard to find. You can buy it from the LG website for a remarkable $900 (!!!) but of course that's not the real price. Heck they are selling a new V30 (regular! 64gb) on the LG website for over $900! LOL! I love my V30S, but it is not a significant improvement. It's nice to have a little more RAM but it's not any different at all besides that. Speed is pretty much the same. Only difference is marginally better multitasking. Worth it for me, but I wish I had 24GB of RAM lol. Heck I want 1 million gb of ram with a trillion petabytes of storage and a 99999 core neural network quantum cpu but hey that's a nice dream.
Actually, I already removed the bootloader unlocked warning. It disappears when you flash the Verizon variant, not sure if that's what you meant, but I have no warning anymore. Also, I had already removed the verizon boot as well, this is easy with ROM Toolbox Lite (choose "hide" not remove).
To clarify for readers, flashing to VS996 (verizon) from an LS998 or a US998 or even US998R (V30S, my current phone), is 100% safe. I've now done it on 3 phones. 2 of them former LS998 converted to US998 through the WTF method and then VS996. And 1 of them my US998R.
(p.s. you may get easily fixable bootloop if converting LS998 on PIE (Android 9) downgrading to US998 Oreo to prepare for bootloader unlock. You can easily get out of bootloop by holding voldown + power for 7 seconds until reboots, then at reboot logo keep holding voldown and then release power for a half a second and hold power again, then do the factory reset and it will get out of bootloop).

Yes, that was what I meant. Verizon firmware doesn't have bootloader unlock warning because Verizon never imagined their phones could be bootloader unlocked. . Of all the 20 variants, only stock VS996 doesn't have bootloader unlock warning (that I know of).
So some people who don't want Verizon firmware but wanted to get rid of bootloader unlock warning started flashing just that specific VS9996partition governing that in Dev Patched LGUP -- and someone bricked their phone.
Because they kept using the same Verizon firmware but didn't realize as their variant is updated they had to also use updated VS996 firmware to replace that partition. (Sort of the same reason you can't be on early Oreo to flash current LOS-16 ROMs.)
Anyway, Devs said to stop doing that, it's not worth the risk.

I agree it's not wise to flash only part of a firmware. Better to flash the whole thing. You can get Verizon firmware to work on most other providers anyway as a bring your own device.
Just keep in mind Straight Talk does not like Sprint phones (you can find out your original model number using LG Mobile Support Tool, which, when plugged in, will tell you your ORIGINAL hardware model number, not your software model.) My friend has a V30 and Straight Talk was a disaster. I would say don't bother with straight talk.
Just use prepaid Verizon instead if you're trying to save money. Activate a legit Verizon phone first and then transfer the sim card into your phone. I was able to get both a V30+ and V30S to easily and seamlessly work on Verizon on VS996 firmware on BOTH prepaid and postpaid plans.
But as for flashing the full VS996 firmware, it will be perfectly fine on compatible models (e.g. LS998, US998, US998R, possibly others but I have not tested).

Sure. I'm the one who wrote the Frankenstein instructions which came BEFORE WTF bootloader unlock exploit.
All the North American variants (EXCEPT for T-Mobile H932) can be completely cross flashed and converted to another: US998, AS998, LS998, VS996, H931, H933, and H932PR (Puerto Rico).
However, of all those, only US998 has fastboot flash commands.

Thank you very much for your contributions! You are making the world a better place.
By the way I'll probably keep this phone until a fully rootable phone on verizon 160g or less weight with a better resolution screen 6.4" or bigger yet not any taller, with better cpu more ram and oled with microsd card slot and a few other specs comes out, and WITHOUT a notch or cutout.
So, I expect it will be years before such a phone comes out. Until then, this phone is the perfect phone for me.

This is not a computer. That extra RAM you want, and what OEM's like 1+ are doing, doesn't really do anything for the device other than make it more expensive.
OEM's are only doing it to please the masses.
