Did you unlock your bootloader with this yet? Two people over in the WTF thread are having problems and both (H930 and US998) are on a July security patch.

They had to flash to respective earlier date KDZ before July security patch and then successfully unlocked bootloader.

Until we find out more...

For bootloader unlock purposes, use the US998 KDZ versions with no later than June 2018 security patch. Look at the names for dates in the title. You can always update to newer firmware later, AFTER bootloader is unlocked.

I figured out what was wrong with fastboot not finding my device.

I had to go to device manager in widows and manually install the "LGE ADB DEVICE" driver from the list. Worked fine then.

I was on us99820b at the time. After unlock, i used lgup to move to us99820d, then flashed twrp. I am now very happy with my rooted lgv30 :)

Someone please help me. I am trying to flash nouget in download mode with LGUP and keep getting the following error;

"LGUP can't load the model"

I have reinstalled it twice now and rebooted my computer and it still will not see the model. What else can I do? Could it be due to the fact that it is sharing the folder with the LG driver? Running as admin I got this log;

Hi. I have an AT&T LG h931 variant. I followed the instructions to get my phone up to the Oreo LG-USH998 hardware status. My question is, can I undo this and revert back to the way my phone was before?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Any particular reason you wish to revert?

Problem is AT&T doesn't release KDZ for firmware updates. So, unless you made a dump there's nothing to flash back to.

People do this either for bootloader unlock and root, or they want regular updates when not being an AT&T customer. Or they want more LTE bands.

I was wanting to get TWRP so I can flash some ROMs on the phone. I'm just wondering now if there is a way to revert. I am not very expert in this stuff, but I at least know a little about what I'm doing. Am I correct that I will be able to flash h998 roms on my AT&T phone if I finish your guide and get the bootloader unlocked along with TWRP?
[LG V30 Guides, News, & Discussion] stolikat:
Is there an alternative to LGUP to flash? I have installed this three times now and keep getting the same error.

Now it shows I am connected to COM3 but the device is unknown. Sigh.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Once you convert to US998 you can continue to update with other US998 KDZ, even without bootloader unlock and root. This Frankenstein method was created even before the Oreo bootloader unlock exploit was discovered by [MENTION=6158380]TxanMoe[/MENTION].

With bootloader unlock and root, you can flash stock- based ROMs like Boombox and AIS -- or remain with just rooted stock firmware. Right now AT&T H931 and Canadian H933 have problems flashing AOSP ROMS, but [MENTION=3475147]SGCMarkus[/MENTION] is working on a solution.

I followed this on my AT&T V30 (H931), and everything worked fine, however I've noticed that I will lose my Verizon signal frequently even in places that have strong coverage. I'll either see an X next to the signal strength, or I'll see bars with no 4G, and the phone will say "Emergency Calls Only."

I've tried toggling airplane mode, switching mobile network from Global to LTE/CDMA, resetting the network settings, rebooting the phone, doing a factory reset, and re-flashing the US998 Oreo firmware.

In addition to this, I've had a problem where I cannot send SMS messages (see this thread for that: https://xdaforums.com/lg-v30/help/s...ankenstein-t3823757/post77230619#post77230619).

I'm wondering if the two problems could be related, and if it could somehow be modem-related or anything like that? I don't know much about how this all works; it just seems weird to have these two issues. Would love some suggestions if anybody has any ideas!

i have a bud that is upgrading from his v30 to the G7. i may buy his v30 off him but he has H931 (at&t)

can i use this method to get to us998 (to do wtf bootloader unlock as well as use it on verizon) or am i better off just finding an ls998 on ebay?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, you can use the H931.
[LG V30 Guides, News, & Discussion] papoose515:
ok so what are the benefits of root for the v30
[LG V30 Guides, News, & Discussion] ChazzMatt:
You own your phone instead of the carrier or the manufacturer.

But this thread is not about root. This thread is about Frankenstein -- converting one variant to another.

People use it to convert a mint LS998 V30+ (128GB, $320) to Verizon VS996 because they are Verizon customers, and that's less expensive than buying a VS996 (64GB V30). Or converting AT&T H931 to US998 because AT&T won't give updates to their phones unless you're a customer.

And yes converting any North America variants (except T-Mobile H932) to carrier unlocked model US998, because it has fastboot flash commands, which are necessary for bootloader unlock and installing TWRP custom recovery.

But this thread itself isn't about root. That would be the WTF bootloader unlock and root thread. ;)

For Canadian H933 owners. It is mentioned under the H933 over on gsmarena, that the LTE-A (3CA) 750/150 Mbps is limited compared to each other variant, which lists LTE-A (4CA) Cat16 1024/150 Mbps.

Anyone who has ever been to Canada knows that no Canadian carrier can deliver 750 down and 150 or anything remotely close to that on their absolute best day under the most ideal conditions. However, it does seem a bit silly to limit the modem of the device when it can potentially do 1Gbit down and 150Mbps up. Band 28/29 700MHz spectrum is hardly used currently, making flashing to the US998 firmware a better option in the long run, if you don't actively live in an area where Bell's band 28/29 700MHz coverage exists and if you don't need or use WiFi Calling on a Canadian carrier.

I personally haven't been able to test the speeds of the H933 firmware off of Canadian networks but I am going to make a point in bringing my H933 with me the next time I return to the US to try on T-Mobile's network, where I should be able to hit and exceed those speeds in southwest Virginia.

Anyone tried it to korean v30's? I want to frankenstein'd my SKT branded V30(LGM-V300S) to get rid of korean bloatwares and features. Is it possible to flash H930/H930K firmware? H930/H930K has minimal to no bloatwares and great lte bands that suits to my country. Thanks in advance!
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, they have. There's a whole thread for people to bootloader unlock and root the Korea carrier variants.

https://xdaforums.com/lg-v30/how-to/korean-variant-bootloader-unlock-root-t3804505

First they have flash H930 to get fastboot flash commands. Bootloader unlock, install TWRP and root. Then they have to flash a special TWRP US998 zip file to get modem signals back.

So, they have to Frankenstein twice. There's even a video showing how to do it.

Just wanted to post my thanks to [MENTION=3250376]ChazzMatt[/MENTION] for the work and detail of this thread. I purchased an LG LS998U (came with the Sprint SIM and all) and in 30 mins was up and running with US99820a SW. Activated it on MetroPCS and everything is working.

Time to read the WTF thread again so I can unlock/install TWRP and root... :D
[LG V30 Guides, News, & Discussion] ChazzMatt:
You've already done the "hard" part. ;)
[LG V30 Guides, News, & Discussion] jdgesmlls:
Now that my bootloader is unlocked, TWRP, rooted etc... I should be OK to use LGUP with the UPGRADE option to go to Oreo 20d correct?

Forgive my ignorance but this is no different than taking the OTA on stock, just an upgrade that doesn't wipe anything? What is your recommendation?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes and no.

1) You would be OK for "upgrade" via LGUP to keep the bootloader unlocked and to initially keep your data. But you would end up with stock recovery, and lose TWRP. You would then have to reinstall TWRP, and flash the no encryption and no root check files, as well as Magisk. In that process I believe you would need to wipe your internal data anyway, as LG encryption would be turned back on. (It seems you would need to do that, just to make sure.)

2) The other option (better in my opinion), is to DL partition flash 20D via dev patched LGUP -- but untick the "recovery" partitions. That way, you keep TWRP. Then boot into TWRP using the fastboot flash commands from the WTF thread, and flash the no encryption and no root check files, as well as Magisk. You would be ahead a step by already having TWRP.

You could even use Titanium Backup to restore all apps + data. Or maybe restore data only from TWRP backup once Google backup restores your apps -- but I haven't done that in a while, so can't vouch how well it works with our phones. I would use Titanium Backup.

3) [MENTION=3642089]westwood24[/MENTION] has been good to make us TWRP flashable zip files of recent European H930 and North America US998 updates. With those, you just flash in TWRP like a ROM and it overwrites the previous firmware like dirty flashing a ROM. His files already have the no encryption and no root check settings.

I pm'ed him last night to see if he has time to do that for us with the recent H930 21A and US998 20D. Until we get that, your options are #1 and #2.
[LG V30 Guides, News, & Discussion] jdgesmlls:
Once again, thanks for the detailed explanation [MENTION=3250376]ChazzMatt[/MENTION]. I haven't had the chance to decide which method I need to use. Do you know if the baseband version has been updated in 20d? I have noticed that this phone seems to want to use LTE band 4 as a priority, and LTE band 12 is the best in terms of coverage/inside penetration in my area. The phone will eventually switch to band 12 but it seem to fight for keeping band 4. My thought was to try the newest baseband from 20d (it looks like the baseband (modem) was updated in 20d looking at the KDZ contents).

I was thinking I could just flash using DL partition the new modem from 20d through LGUP as well.

This could all be a futile or extremely stupid, being I am 3 days in with this device... What are your thoughts?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, you could flash just the modem of 20D if you wish, for now. I do not know what other improvements if any are in 20D.

Which version of Oreo (21a or 21b) did you perform the bootloader unlock/TWRP/remove encryption/root/disable verity etc.? As it states in the description, you can't use 20d for any of Frankenstein/WTF. If you did this all successfully, you should have been up and running on 21a or 21b with root and encryption disabled... correct?

Are you now trying to perform the steps in the WTF thread to get to 20d?

it was 21a but i not sure to be honest i did the Frankenstein before I did the unlock, but never load it crash on me and them everything when to hell, I'm so upset. I think i brick this phone.

[LG V30 Guides, News, & Discussion] jdgesmlls:
So you cannot confirm you went through these steps successfully?

Also, you reference '21a', where did you get this KDZ? I only see a '21a' version referenced for the H930, there is no '21a' for the US998. Did you mean '20a'?

Once in download mode, does it stay in download mode or reboot to bootloader? If you have an unlocked bootloader and access to bootloader mode (fastboot), I think you have some options to recover. I am not knowledgeable enough about this device to know the low-level recovery methods using fastboot (if they exist).
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, but first does it ever finish booting? That annoying bootloader unlock warning will ALWAYS show up after you unlock your bootloader. Ignore it and let it finish booting.

Make take a few minutes that first time after bootloader unlock.

Then you can flash 20D. Don't flash 20D until.successful bootloader unlock with earlier SAFE firmware like 20B.

You can't bootloader unlock on 20D. So you must have bootloader unlocked on earlier firmware, then tried to update to 20D?

Please tell us every step you did, in order.

NO! You have to go from 10D Nougat to 20A or 20B. You specifically cannot flash 20D before bootloader unlock. 20D blocks the bootloader unlock exploit.

Yet your images show bootloader unlock warning, so I am confused exactly what you did.

[MENTION=3250376]ChazzMatt[/MENTION] - I am thinking of doing a fresh install of US99820d from Partition DL to root (all steps in between)... I don't mind making a backup of the freshly installed US99820d FW in TWRP before I do initial setup. Is this essentially what [MENTION=3642089]westwood24[/MENTION] does to create the TWRP zip ?

Is there anything else I should do to make a US99820d TWRP zip so other can use it to update to the latest?

Almost forgot... I plan to use LG Backup to restore apps/settings and Titanium Backup for user data... I used to use this when I had my G3 and it worked well for stock LG firwmare.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Thank you for doing that.

As for what [MENTION=3642089]westwood24[/MENTION] does, I assumed he has some software method to just compare and replace the partition/paritions of TWRP flashable KDZ with what is new and what he wants to keep. Especially since he did both H930 and US998. I really don't know.

Back in 2015, I made a bunch of TWRP flashable images for Motorola QUARK XT1225 -- ranging from full stock Kitkat (non-rooted, with stock recovery) to full root with TWRP installed -- and posted them for others to use.

But it's been a long time since I've done that, and those were not for LG phone, but Motorola.

Sure, go ahead and do it and just say users can use it at their own risk. Create a thread and I'll link to it from the US998 KDZ thread.

Do you think you could make a full back up of the AT&T firmware to post before you flash? Once you flash, you won't be able to go back because AT&T doesn't post their images for the V30. I actually would like to turn my H933 into an H931.

[LG V30 Guides, News, & Discussion] ChazzMatt:
1) If you really do want H933, you can flash directly to it. No need to flash US998 in between.

2) US998 is the North America carrier unlocked model. Living in Vietnam, is there some reason you want/need Canadian H933? They both have almost identical HSPA/LTE bands.

I understand you don't need root, but it never hurts to have fastboot flash commands. (US998 has that, H933 does not.) Unless there is some specific reason you need Canada H933, then North America US998 is actually the better choice for most people, and resale value would be higher.

Well holy hell that did not go as planned. I am just now restoring my apps and getting my device up and running on 20d. I was getting some odd behavior, apps crashing and unable to add accounts at setup with the screen going black. The LGBackup restore was successful (that was about 3 hours ago) but it took almost 90 minutes to restore 3.4 GB.

I decided to stop trying to get the first 20d flash fixed and went back to download mode, and partition DL flashed 20d again (choosing all partitions) and it succeeded. When it booted back up, my previous configuration was still there. I was able to do a master reset and get a stable 20d running with encryption. I went through the steps again in WTF to install TWRP, remove encryption, root, no-verity, and remove root checks. It seems to be stabilized now.

I wasn't able to attempt trying to create a flashable 20d TWRP zip, I need to do some more research on that... I am hoping [MENTION=3642089]westwood24[/MENTION] can work his magic in the meantime...
