EDIT: THIS POST WAS WRITTEN IN APRIL 2018. We've since discovered more about Frankenstein method and I've personally bought two LS998 V30+ and converted them to US998 V30+

______________

Where are you seeing 1.18? As of a few days ago 1.14 was still the latest we could find. It works.

Also make sure you're using the patched LGUP. You want the Partition DL option.

______________

The dll files are not by carrier, but OS version. We already told you which dll file to use, the Oreo one down in Development, since you are on Oreo?

LGUP Oreo DLL File for V30

https://xdaforums.com/lg-v30/development/lgup-oreo-dll-file-v30-t3779441/page2

If you want to stay on Oreo, instead of flashing a Nougat US998 KDZ, there's an AS998 Oreo KDZ also in Development you can flash. AS998 is for "regional" carriers. It's basically the same thing as US998.

[AS998][STOCK][Oreo] Android 8.0 20B Official KDZ

https://xdaforums.com/lg-v30/development/as998-oreo-20b-kdz-t3780930

Many Sprint V30/V30+ and Verizon V30 have been flashed to US998 and AS998 KDZ by cell phone resellers. Especially Sprint, because those are carrier locked. One Canadian H933 V30+ showed up, which doesn't exist in real life. It was obviously a former Sprint V30+, flashed to H933.

This method is how it's done. But is it this method PLUS the LG Octopus box? (Google it) Or just this method?

Also see this post:

https://xdaforums.com/showpost.php?p=76216489&postcount=92

The Asian cell phone guys are doing this every day, so they know.

If you are on Sprint, and are currently using your Sprint phone, I am urging caution. Your phone is working right now. If you don't feel comfortable doing this yourself (and maybe additional tools like that Octopus box is needed?), then find a 3rd party eBay person like that above. They are out there.

For others who bought a Sprint phone and aren't even Sprint customers, those are the ones who have nothing to risk. They already have a useless phone.

____

I confess I don't understand people who buy Sprint phones who aren't even Sprint customers. There is always so much drama in the XDA forums with people begging for ways to unlock Sprint phones. Just don't buy them to begin with? Why go through that hassle?

Especially before this method was discovered, which we are still exploring.

Personally I think buying a U.S.Cellular model V30+ -- which is carrier unlocked out of the box, and was even released BEFORE Sprint released their V30+ -- would be the better choice than trying to buy a known carrier locked phone and then desperately trying to unlock it.

Sorry, my mistake! it confused me bc folder name is: version1.18 but that is LGUP 8994 DLL program that I also installed. btw. What is that n do i need that??

Doesn't work for me! :crying: I install LGUP then take oreo dll file and put that file in the Program files(x86)>LG Electronics>LGUP>model>common (paste the file)

and no matter what it always is saying: your dll file is invalid...??? Why? Please Help!
[LG V30 Guides, News, & Discussion] datrmon:
I think we need to know the missing step during the crossflash. It is too great a risk since we have some people who go their phones bricked.

All the steps we have get the AS998 oreo, lg up and dll for oreo and partition. That's all. Nothing about using Octopus. We need someone to explain this.

I need someone.on Skype I can work with to put me through

After going back and forth getting scared of crossflashing for a couple of weeks.

I finally did it(Used AS998), it just like Moriatier said. worked and the phone is now sim unlock.

It is as simple as described by the OP. follow the steps and make use of the files as specified by ChazzMatt

Thank You

You should pull that image and cover up your serial number. What version did you start with before flashing to AS998?
[LG V30 Guides, News, & Discussion] Moriatier:
glad to know. you are always welcome to ask questions in that little group
[LG V30 Guides, News, & Discussion] ChazzMatt:
This means all Sprint V30/V30+ can be sim card unlocked/carrier unlocked using this method.

However this does NOT get the phone off the U.S. carriers' bad ESN list, is it's on that. But that only matters if you use the phone in U.S.

Be careful. Changing IMEI can't be discussed on XDA.

It's illegal in some countries and banned from discussion by XDA.

I mentioned it earlier in this thread because it was discussed in another thread, and seemed relevant to this topic.

However, your OP method worked to cross flash successfully without an Octopus box, but many pro cell phone flashers use it so it must do SOMETHING.

Yes i SUCCEED everything, and it's so easy to flash as998 on ls998, but DO NOT TRY TO FLASH US998 TO LS 998 I TRIED THAT ON MY SECOND V30 LS998 AND NOW IT'S BRICK and I don't know what to do. I can go into download mode but then even when i repeat whole flashing process with flashing as998 on my "brick us998" it's still a brick so I don't know what to do now with that one lol? help!?
[LG V30 Guides, News, & Discussion] jcsww:
It's under warranty. Maybe try an RMA? If you can get into download mode though, you should be able to get something to flash. Why not flash it back to a US998 and see if that works? If your V30 ends up my H933 did, then that's definitely a brick you can't recover. No download mode, boot logo, or anything. It was all black screen all of the time. :P
[LG V30 Guides, News, & Discussion] ChazzMatt:
Have you tried a data reset, like post #1 suggests -- if you run into trouble?

Or maybe that's where the Octopus box comes in. Maybe it helps people flash to other versions when it's otherwise very difficult.
[LG V30 Guides, News, & Discussion] jcsww:
I'd be interested in one if it could force flash my H933 without bricking it to another model of the V30.

SafetyNet "the response is invalid"

[MENTION=3250376]ChazzMatt[/MENTION] - Are you running a rooted 20d FW? I am getting an error "the response in invalid" to safetynet check in Magisk Manager. The lastest Magisk Manager is 5.8.3, and I tried going back to 5.6.1 packaged with Magisk 16.0. I don't remember not having an issue on 20a, I wonder if this has to do with the July security patch.

The thing is, everything is working. I am using Magisk Hide from the Google Pay app and it opens and appears to work fine.

Anyone else running rooted 20d able to pass SafetyNet?

I just wanted to post and say thanks so much. my LS998 came in from ebay an hour ago. got it for $315 and its in MINT condition. im shocked how good of condition it is. i hope nothing shows up randomly after using it but so far so good.

I used your guide and flashed the nougat file and worked but for some reason it still showed up as LS998. i just flashed it again and worked. shows at US998 now. updated to oreo US99820b!!!! now about to do WTF !!!

question though. Where can i find the Verizon modem (radio) files. i plan on using this on my verizon service and recall reading about people that want visual voice mail and wifi calling i need to flash these radio's. do i use LGUP to do this? and also how do i go about updating to the latest security update after unlocking the bootloader?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, once bootloader unlocked and rooted you can go back and flash the VS996 modem partitions in dev patched LGUP with DL PARTITION method, but you would untick (uncheck) everything except for modem partitions.

You can find the Verizon VS996 Oreo KDZ down in development section.

YUP... STAY AWAY FROM MAGISK 16.7... on 20d anyway

I installed in TWRP, wiped cache/dalvik and rebooted to 'Service Disabled' for all radio. I then rebooted and device was stuck at the LG V30+ screen. I tried to power off the phone but it wasn't responding (I thought I was in trouble). I then held volume down and power and the device responded, and it rebooted. When it came up, everything appeared to be fine, all radio was back. I then rebooted again to recovery, and wiped cache/dalvik and rebooted system. It again came up with 'Service Disabled', no radio. I rebooted to recovery, and used the latest Magisk uninstaller to remove 16.7. I reinstalled 16.0 and it seems like everything is OK now...

The 20d FW with July security patch seems to be a bit temperamental. :eek:

So, I had just bought what I thought was an open market US998 V30+ from ebay. What I received was a converted LS998 V30+ that is stuck on nougat. Is there anyway to receive OTA updates to go to oreo or do I have to flash up. I dont like the hassle and am worried about bricking my phone.
[LG V30 Guides, News, & Discussion] jdgesmlls:
I haven't come across an app (even Google Pay) that complains. I downloaded two SafetyNet check tools and they both FAIL. Magisk 16.0 passed SafetyNet on 20a, so it is something with the July security update.

Easily update to Oreo and keep data.

You're already on Nougat, you're just doing a simple update to Oreo.

Full image KDZ is preferable to partial image OTA anytime.

So MUCH stuff can go wrong with OTA updates.

awesome. downloaded it. having issues now with LGUP now seeing my phone in bootloader mode (download) did before. windows see's it under device manager but when i open LGUP it says there is no handset connected.

is this a driver issues or is it because of LGUP?

LGUP see's the device while booted normally just not in bootloader mode.

**EDIT**

nvm figured it out. im used to my pixel and past nexus devics. im used to bootloader mode also being download mode so i was in bootloader not download so it was not ready to seeing it right. just flashed verizon modems from VS99620d. now my goal is to get the google phone apk from this thread https://xdaforums.com/android/apps-games/app-google-phone-v14-0-175904292-bubble-t3708218 to also give me visual voice mail like i had on my pixel xl.

Long shot... If LgUP recognizes it in fastboot mode you can try to start a partition dl (maybe even refurbish or board dl) and it should try to boot into download mode.

Although it sounds like the laf partition(contains download mode).

Phone doesn't try loading the os at all?

In developer settings there's a setting "OEM Unlock" that has to be enabled to use fastboot mode.

Love it.

Just cross-flashed a VS966. LGUP was still recognizing it as a VS99610d after the US99810d Nougat flash. Multiple master resets and couldn't get it to read as a US998, which meant LGUP didn't want to do the "Upgrade" flash. Risked the all-partition flash to US99820b Oreo and everything looks good.

Gonna flash the radio back to Verizon then start with the rooting. I'll let you guys know if anything goes tits-up, but it gets porn and posts on FB so as far as I'm concerned it's working.

As somebody in another thread so eloquently put it: "suck it, Verizon."

edit: oh, yeah, something else of note: mine hangs at "now waiting for any connection..." when in download mode and LGUP will not recognize it until you unplug then re-plug the cable, which gets it to flop over to "do not unplug the usb connection until the process is complete" with a 0% bar, at which point LGUP will recognize it. If LGUP is started while I do this re-plug it will show as "unknown" for the device and I have to restart LGUP - I assume this is what you meant when you said make sure to have it plugged in before starting LGUP. I am using the patched LGUP from this thread for both steps.

And LGUP is still reading the damn thing as a VS99610d. Ahh well :)

edit^2: flashed VA99620b modem only (partition flash, still using patched LGUP+V30DLL) and still have LTE, porn, and FB. Still winning.

edit^3: Can't get my Windows or Linux to recognize the device in fastboot. wth? Nothing in dmesg. Nothing in device manager. 1.4.3 snoop05's Google USB drivers installed on Windows. Gonna recompile kernel and look at this after I've gotten some sleep. Suggestions welcome. Worst case ill start over if those don't work.

Oh and LGUP started recognizing it as US998 tho dunno why.

If do that do I lose some LTE band or all of them or GSM modem will not work anymore because of firmware differences.

It's called Master Rest and is the next step in the Frankenstein instructions after flashing Nougat US998. You "SOLVED" by finally reading the instructions. ;) See how point #3 follows point #2?

In the longer form of the instructions I clearly explain flashing US998 Nougat, while very necessary, is also very unstable and you need to do this Master Reset. After that, then you can easily upgrade to Oreo US998.

Sorry if it sounds like I am coming down on you, but there was nothing wrong. You just didn't follow the listed procedure. Over in the WTF guide, someone else today asked questions that showed they didn't really read the steps either.
