Remember you're doing this at your own risk. I won't be hold responsible for any damage.
Read and follow steps carefully.
First follow the tutorial to unlock your bootloader, install twrp and root.( https://forum.xda-developers.com/lg-v30/how-to/korean-variant-bootloader-unlock-root-t3804505), after unlooking the bootloader,
flash twrp flashable v300l android 8 rom( 2019 prefered) and boot android first.
Go to developer options and enable usb debugging and OEM unlocking if is unticked.
Now download v300l pie rom and flash with LGUP( Use the dualmode version to get all options), but this time choose refurbish.
After it successfully boot, go back to enable developer options and enable usb debugging.
Now Download H930 pie rom you like and flash with lgup but this time choose partition dl then click start.
Now this is the important part, when the partition selection menu pops up, select all partitions except xbl, xbl 2 and modem, these three partitions must be unselected or unmarked then hit ok to flash.( if you dont unselect them, it will flash H930 Modem and you wont get network since the korea variants and Global variants dont have the same modem. unselect those 3 options to retain the korea modem)
After it finishes, hold the volume down and power button to got to recovery and do factory reset.
Wait for it to finish booting and configure to get your lg v30 korea variant as a global version.
Notes:
Any time there is an update, please use the LGUP to flash kdz and select partition dl, and leave xbl xbl2 and modem unselected or else you will not get network or service signal.
Never use a flashable zip or else you will get softbrick( you can use a back up global rom to restore as update but make sure you dont select modem anytime youre doing update)
sometime registering network seems to take longer time, be patient.
You can also root by using the recovery installion method and root using twrp.
I dont know if this will work on the other korea versions but you can try.
You can now flash any aosp rom made for H930 you want without any problem because your device is now global version.
Please Fm radio will never work because the Korea Variants don't have Fm hardware. LG replaced the Fm hardware with DMB hardware for Korea market.
Saying thank you will be appreciated

Please just to verify, you mean all custom roms available to H930 can now be installed on V300L?

yes. every rom for H930 works on v300l with a single problem unless that rom is buggy.

But just covert from v300l to H930 first or else you wont get network signal. follow the tutorials and you will see the magic
just finish converting mine. V300S
from v21e
1.i flashed v300s 30h
2.next flashed H93030q_00_OPEN_EU_OP_0902.kdz (unchecked xbl,xbl2,modem)
3.flash TWRP-3.2.3-7-DataIMG.img
4.from twrp: flash magisk v19.4, dm_verity, ak3_rctd remover.
reboot successfully with signal and data. buy one thing i notice, there is no 3g/lte indicator under signal icon. but then again, i have data connection.
Now, my concern is:
1. if I backup my current stock rom (h93030q) via twrp, then i restore it via twrp. will I get softbrick?
2. what twrp version must prefer to install custom rom?
3. what are the working custom rom do i use?
4. whats the proper step in twrp to have a clean install for custom rom?
5. lastly, when im in custom rom, can i go back to stock h93030q via RESTORE on TWRP?
Earlier i flashed v300l rom step by step but i got no signal so i revert back to us998 20h oreo. But still i lost signal. (When i search it shows "error while searching networks) and (i check ims status in *#*#4636#*#* the n phone info and tap three dots and ims status. Ims status : not registered) my original device is h931 converted to us998.
I done everything flash rom in DL/Refurbished but no success till date. So if you guys have any fix please help me. And yes i don't loose imei number , i have it but no network. And wifi not able to search Wi-Fi's every time i need to restart to connect wifi. Sometimes it connect. Till restarting for wifi connection.
hi guys. this method works well, but network searching is too long, because firmware is searching for a second sim. At Oreo roms it was possible to fix it by changing (removing) persist.radio.multisim.config property in build.prop or OP folder. is there any way to fix it at Pie?

ok guys, i found a solution if you have root
edit file /vendor/bin/init.class_main.sh
about string ~120-130 find
multisim=`getprop persist.radio.multisim.config`

and change it with

coming from v300s pie and flashed h930 30q. my only problem is lte/4g icon on statusbar, how can I fix it?
no Vietnamese language
Hi bro. Can it be used with volte?
The guide look promising and I would like to try it on my V300L that I bought to replace my H930 with a smashed screen (unfortunately a screen assembly would have cost more).
But I got two questions before trying it out:
1. The Bootloader unlock and root guide is based on Oreo, but I got my V300L on Pie, unfortunately (V300L30h). According to the hidden menu, ARB is 0 for APPSBL, SBL1, TZ and RPM, so it should work, right?
2. My goal is to convert the firmware to the EU variant, but I don't necessarily need a bootloader unlock or root myself. In the bootloader unlock guide you are supposed to flash the H930 firmware as a whole, including XBL, XBL2 and modem. So it seems like the V300L and H930 firmware is signed using the same key. As bootloader unlocking requires to reflash the firmware multiple times, which is not optimal for the EMMC chip, and bootloader unlocking could introduce some hassle with some apps, I wondered if it was possible to flash the firmware directly without peforming the bootloader unlock first, of course without flashing XBL, XBL2 and modem. Unfortunately, I don't really know how Qualcomm's chain of trust works, but I can imagine that having bootloader stages from different device firmwares might trip up the validation and I really don't want to mess up the bootloader chain.
Thanks in advance

??? I think you are confused about something.
All actual H930 firmware is single SIM. LG H930 and (even LG H930G) are single SIM phones.
There are only two "V30" dual SIM variants -- H930DS and H930D. So don't flash H930DS or H930D KDZ.
But actual H930 is single SIM. So, any LG stock KDZ for H930 is single SIM. The hard part is finding dual SIM KDZ not avoiding them.
________
I'm a little confused by "ROM". Are you talking about LOS custom ROMs? Or stock firmware TWRP flashable zips built like ROMs? Or are you merely using the word ROM to describe LG stock KDZ? In the OP, they use the word "ROM" to mean LG stock KDZ, so I will assume that's what you mean.
sorry that's for stock kdz. as i have v300s and converting to h930. this is the file i fl(H93030q_00_OPEN_EU_OP_0902.kdz) but it has a dual simcard option in settings.

That's a single SIM phone. It is compatible with dual SIM H930 variants (DS and D), but H930 is a single SIM phone.
If it has dual SIM card option, just ignore it.
Early Oreo H930 KDZ didn't have that option and H930DS people who flashed that couldn't use their dual SIMs.

i can confirm what @dchinacay has said above with regard to stock H930 30q firmware having Dual SIM option in Korean V300 Frankenstein; is that option visible by default in non DS version of H930 too?
i have just converted a V300S to H930 Pie using method by @darkidz555 and @Amosika and flashed the stock H930 30q KDZ firmware from your mega upload last to achieve that.
many thanks to everybody that has contributed to this marvel!
while signal searching was instantaneous when the phone was still in its V300 state, it has slowed down noticeably as a H930 now.
is the slow down due to the Dual SIM option or because the phone is now searching for networks in bands not supported by the V300?
hope some gurus can shed some light and maybe we can solve the problem with a simple config file edit.
(i did not try the suggestion (https://forum.xda-developers.com/showpost.php?p=80558959&postcount=7) by @viktor.s as @dchinacay has encountered problem with it.)
@dchinacay, I do have 4G on top of the signal bars when mobile data is in use (wifi off or when not connected to wifi).
Dual SIM and slow signal search issue resolved!
I accidentally stumbled upon the solution for slow signal search after conversion to H930.
As I did not uncheck the box beside recovery and recoverybak for Partition DL when flashing H930 30q KDZ firmware, I had to reflash TWRP after 30q.
As known, Format Data is required during the first boot in TWRP recovery for TWRP to work.
After formatting data and rebooting back into TWRP recovery, I went ahead to flash Magisk 20.1, Disable DM Verity and RCTD Remover.
To my surprise, after the phone has booted into android PIE, there is no more Dual SIM option and the 4G cellular signal caught on almost instantaneously, like how it was when the phone is still a V300!
@dchinacay, the 4G signal icon display went back to that of V300's too!
Hope the above works a treat for all those facing the same issues!

He did NOT uncheck the recovery and recovery_bak, so he wiped out TWRP... Which actually solved his problem. He then re-installed TWRP, reformatted his data (necessary), flashed Magisk 20.1, Disable DM Verity and RCTD Remover.
He basically followed these steps:

So I was on Oreo and accidentally flashed back to 7.1.
Didn't brick it but now it doesn't recognize my sim even after flashing back to Oreo.
I tried to fastboot the tmo baseband but no luck there.
Anyone run across this or have any suggestions?
That was one of the 1st thing I ran across in the Oreo update thread. With development just really getting fired up I'll be surprised if you find a fix. If. I was you I would flash the mod that hides the unlocked bootloader warning and take it to TMobile. It's only a 5 dollor charge for defective devices. I've returned a total brick before.
So I am on the same board. The problem is I'm in UK and I cant claim warranty repair. Also my warranty was void in December soon when I generated bootloader unlock key.
SO what have I tried so far?
Hard brick bootloader to state when it is Qualcomm loader- only blank flash and Oreo Flash All is able to bring it back to live.
Ive also tried boot from B slot in twrp but it looks like my B partition is messed up. Fastboot will show red warning about no flashable A/B slot and only oreo flash can get it back to boot because it will oem lock itself.
When I get back fully on unlocked bootloader to 7.1.1 I cant update via adb sideload or update menu in settings. Both will fail.
Sim looks like it is detected on start but when taken out and slided back in it wont show up.
I have QCN area backed up with nv data but it wont help me.
Please note when boot is bricked oreo flash all will flash it on locked bootloader and will not show warning screen at all about botloader. However I was unable to boot to recovery from that point so I had to unlock it and flash 7.1.1 then oreo again.
So if someone could do nandroid backup of clear not set up rom it would be great. I can try restore it. I dont even know if twrp is able to do backup on A/B device.
Also if someone could read NV data from phone and share it ( from phone with working radio of course) would be really appreciated.
Can someone PM me NV backup? I need urgently qcn file. I think my hw partition is messed up. Please don't share it in this post as it can contain IMEI.
this is what i did, and why there is a giant post in caps in the thread that says not to do this. You essentially end up with a bootloader mismatch which hoses the radio. the only solution is a replacement.
and DONT DOWNGRADE !!!

Sorry but warning isn't clear. I did not enjoy Oreo and was looking for unlock method.
Also bootloader match to my current Oreo rom and radio but still no sim detected so I think it is hw partition messed up. When I flash retail Oreo on it bootloader just change itself to retail Oreo version. Still no sim.
Device is useable as paperweight with WiFi
I think I've found a way to unbrick your phones guys!
If someone still has their bricked phone could they tell me what state they're in? I managed to successfully unbrick mines but had to stay on 8.0
Everything about the phone works 100% except the Sim slot. It's like it can't read the Sim. It knows there is a sim in, but it can't access it.
On Oreo oem retail version.

I'm happy to stay on 8 but need my sim get back to life. All works fine except SIM card is not detected.
My phone boot as normal. When downgraded it won't accept ota's. It won't install it via sideload too. SIM card remain undetected no matter what rom and what version( T-Mobile, retail, etc) when I try to boot from slot B via twrp it won't boot. It will show bootloader screen with unbootable a/B partition.

Not OP, or guy with a link, but I did a similar bad thing and ended up on the retail Oreo without working SIM. What I did was take the modem file (the one that you fastboot flash to modem) from the tmo oreo zip and replaced the modem file in the retail oreo zip with the tmo one -- just change the name of the tmo modem file to the one that comes in the retail oreo zip and then run the retail flashall.
Still no way to get the latest tmo update that fixes some volte issues, though. Since I purchased within 14 days, I just added insurance and will probably end up drowning the phone to replace it... unless someone has a better idea. :/

G'day everyone!
Much like @mr turtle droid , I've decided to create this sister thread to keep us all informed of the progress towards Root, TWRP, and ROM's for the CARRIER UNLOCKED LG V30+ variant.
At this point in time (15:50, 21st Feb 2018), LG HAVEN'T placed this model on their Unlock list, on the LG Dev website. The LG Models that ARE there are the H930 and the H930G for the Euro market. I've emailed LG Australia about this, and am still waiting on a response, but doubtful I'll get a helpful one. I've also asked on the LGDeveloper twitter page, and received a stock standard response: "We are sorry that we can't be of much help. If there are any changes to the supported devices, we will let you know via our website".
Not being a dev myself, I don't know if any fastboot commands work or not, so if someone can get us going with potential methods, that'd be sweet.
I have a link for the Firmware *.kdz downloads, for what it's worth. Link is found HERE.
If anyone has any ideas, please share them. The more that we know, the closer we get to unleashing the full potential of this great phone.
Also, if someone could explain why exactly LG doesn't unlock all the different models of their flagship, or at least give an ETA for the unbranded one's, that'd be sweet. Is it because of licences, or patents or something? Or is because it's a Dual SIM model? Curious more than anything.
It just seems nuts to me that the V30+ that I bought from JB Hi-Fi wouldn't be on the unlock list, if it's an unbranded / noncarrier variant.
Once again, this is for the carrier UNLOCKED variant, H930DS.
If the bootloader is unlocked on the H930DS then this thread might be a step in the right direction for route

Hi, reports on there suggest that only one sim is working after using that method.
Seems like flashing back some partitions from another ds model with lgup could be the solution.
I have been tempted to buy this phone only put off by no root.

Is second sim not working at all, or is it possible to use it as a data connection only?
Hi, I have only had mine for 3 days so haven't tried yet
I think as a H930 single sim unlocked bootloader is loaded, you will only see 1 sim.
Dont quote me on that as I am still reading up
Any experts who can answer?
Both SIMs work for H930DS. Just flash unlock bin and TWRP as described in WTF thread. Need to mention that I've had official H930DS Oreo update prior to attempting this.
Hi, well thats the first time I have seen that stated.
There are no specific instructions for the DS.
Are the one's with only 1 sim just flashing a single sim rom and keeping it for the bands or something?
I have V10e-AME-XX and no Oreo update is showing.
So do I
LGUP to convert to open single sim H930
Adb reboot bootloader
fastboot flash unlock new_unlock.bin
Install Twrp
Then how to get dual sim rom?

I wouldn't flash single sim rom on a dual sim device if I was you. You need to flash Oreo dual sim firmware and then everything is straight forward. Bootloader unlock process as well as flashing TWRP won't effect any fuctionalty and procedure is simple.

I have a H930DS flashed with H930 firmware. It's rooted with Magisk installed. Both SIM slots are working. Both data and calls are fine.
I used the H93020d_00_OPEN_EU_OP_0326.kdz firmware.
The phone is still identified as a H930DS and the software version is called V20d-GLOBAL-COM

Thank you. So you flashed the H930 Oreo KDZ. Just like the instructions say in the WTF thread.
To me, the only way for H939DS users to do this is to flash H9390 and run the command. One India H930DS user says that is what he has done and he has BOTH SIMS. Now you have confirmed it. That's two H930DS users who have bootloader unlocked and rooted, just like I said they could do -- and they both retained dual SIM functionality. Every V30/V30+ can be bootloader unlocked and rooted, except for the T-mobile H932.
Even @crubbish seems to infer that but he contradicted himself -- saying he didn't flash the H930 firmware, which I'm pretty sure HE HAD to -- which is frustrating.
hmm, so I have just re-run LGUPP and device is recognized this time but I get and error 0x8... Please us latest dll LAF protocol version is not match
Do I need to go back down to nougat and them back up again?

No, the H930 variants (which include the HD30DS) do NOT need to downgrade to Nougat.
You just need to figure out how to install and use the LGUP.

I wouldn't flash single sim rom on a dual sim device if I was you. You need to flash Oreo dual sim firmware and then everything is straight forward. Bootloader unlock process as well as flashing TWRP won't effect any fuctionalty and procedure is simple.

@crubbish, I'm sorry but you seem to be contradicting yourself. Please clarify. You either used the WTF instructions or you didn't.
I WROTE the instructions for the WTF thread and they clearly say all H930 variants -- which included the H930DS -- needs to flash the H930 Oreo KDZ to get the fastboot flash commands. So, unless you are saying you somehow managed to enable those commands some other way (and H932 T-mobile users would be all ears for that!), then you did indeed flash the H930 Oreo KDZ, did you not?
Two other H930DS users -- at least one from India -- have used the WTF method, of course flashing the HD30 Oreo KDZ -- and they are bootloader unlocked, have TWRP custom recovery, rooted, and have dual SIM functionality.
Unless you have figured out some other way, THAT is also exactly what you did.

If you've connected the phone to a USB3 port, try a USB2 port instead. That usually works.
Also, if you're not using the cable that came with the phone, try that as well.

No, you need a newer DLL for LGUP which can be found in this thread: https://forum.xda-developers.com/lg-v30/development/lgup-oreo-dll-file-v30-t3779441
Put it in the C:\Program Files (x86)\LG Electronics\LGUP\model\common (create the "common" folder if it's not present). Start LGUP WITHOUT Uppercut.

Thank you.
Besides trying a different USB port or different cable, also try to enter download mode manually (power off completely, then hold volume up button while plugging in USB cable), THEN open LGUP to make it recognize your phone.
Also, try a different computer if none of those suggestions work.

I've had Oreo OTA flashed on my H930DS after which I've followed WTF procedure without flashing any other firmware. Sorry if I wasn't clear on this.
It looks to me that as long as you're on official Oreo firmware you can appy unlock.bin straight away, no need to pre-flash any other firmware. Also someone has reported on losing dual sim functionality after flashing plain H930 firmware, that's why I think it's safer to flash specific dual sim rom for dual sim devices.

Just posting this to have it here in XDA.
Some people may want to try flashing the Canada modem via patched LGUP or may wish to return to H933 stock at some point even after unlocking their bootloader, installing TWRP and rooting.
Wait a sec, I'm not understanding this. It gives us stock oreo? Will this allow us to unlock/root etc?

Not open market "stock" Oreo but "stock" Canadian H933 Oreo KDZ. No changes, nothing added or removed. It's not a custom ROM. It's just the Canadian Oreo KDZ rolled out for all Canadian carriers back in April.
No, it won't give you root by itself as there's no fastboot commands available on H933 -- but it may be possible to flash part of the firmware or modem back after converting to US998 and rooting in the WTF bootloader unlock and root thread. Much like the Sprint and Verizon guys did to get back LTE bands or Wi-Fi calling.
I don't know, just posting it here because it wasn't available here on XDA and the other places may disappear if anyone needs it.
Any chance to relock the bootloader after restoring the original H933 if I decide to go down that route?

@ChazzMatt, am I understanding this right that there isn't specific KDZ for each Canadian carrier version? So if I wiped, flashed this (I've asked about how to do that in another thread) then reboot and insert the SIM card, any carrier specific stuff would be applied?
What I'm getting at is Freedom Mobile says VoLTE and VoWIFI only guaranteed to work on a V30 that was bought from them. But if they are all the same and get customized by updates after joining the network, then it shouldn't matter as long as its a H933? They seem to be suggesting otherwise but that may just be a generic CYA for them to cover other devices that may actually have unique variants for different Canadian networks?

Yes, that is my understanding. All Canadian carriers use the same KDZ. When you add their SIM card, I belived that populates whatever features they have. (See my explanation below and a reason this may not work.)
This is also not the most recent kdz for Canadian phones. It's just the most recent one I posted; others are available.
https://lg-firmwares.com/lg-h933-firmwares/firmwares/
Ignore that they also list carrier. I'll explain. Let's use OPEN ESA in SouthEast Asia as an example. India (IND) is part of the Open ESA region which includes Indonesia (IDN) and Philippines (PHL). An Open ESA KDZ has all the features of all the carriers in that region. If you install an open ESA KDZ which is labelled "Philippines" or "Indonesia" on an India H930DS phone, it automatically gives you INDIA LG service app as well as India carrier Jio VoLTE. Oreo KDZ for Open ESA region was available in those other two countries for almost two months before it was officially released in India. You could download the Oreo Open ESA KDZ online, install it on India H930DS, have Oreo. It would show INDIA build number, would be customized for India. BUT some India users kept saying, "But we want INDIA KDZ." I kept trying to explain, THIS IS INDIA KDZ! It's just not released in India yet...
Now, on that list above of Canadian carrier KDZ you can download, note that 20f FROM ALL THE CARRIERS ARE EXACTLY THE SAME SIZE. And they all have the same TITLE. WHY? It's exactly the same KDZ. :silly:
Now, here's the question I cannot answer. Was it an India SIM card that made India build number populate, India apps be installed -- or was it IMEI number? I think it's SIM card.
"Freedom Mobile says VoLTE and VoWIFI only guaranteed to work on a V30 that was bought from them"
"Will work" and "guaranteed to work" are two different things. "Guaranteed to work" means the'll even replace your phone if needed, and highest levels of technical and customer support. That comes if you buy phone from them. But if features populate on SIM card and not on IMEI registered to Freedom, then you don't need their phone -- just their SIM card.

@ChazzMatt
I am still not familiar with the LG tools and must be doing something simple wrong here.
My device started as an H933
I converted to an H998, oreo (20D I think) bootloader unlocked, rooted, twrp.
I want to return to stock H933.
I have installed windows drivers, LGUP, the dll, etc. So I can launch LGUP, and detect my device. I go to the main LGUP screen, select update, select the H933f file downloaded from above, and start. The phone goes to the Firmware Update screen. LGUP goes to 4% and then errors saying something like Error 4, not compatible with cross device H998 to H933.
I am using the LG common. Maybe it should be patched?
Thanks for any guidance

Yes, you need dev patched LGUP. You are converting (back) to another variant. You will DL PARTITION again via dev patched LGUP, just like when you did Frankenstein the first time.

When I'm not in DL mode, it puts the V30 into DL mode automatically, then generates the error. But when trying to diagnose the problem, I did spot a reference (by you I think) saying to go to downloader mode before connecting, so I went back and did that. Same result. :crying:
The original install wasn't there. I have a MacBook so I borrow access to a PC for this.
Update: On the PC I uninstalled the LG drivers and all LGUP related software. I spotted LG Bridge so I uninstalled that too. I went into task manager and killed LG related tasks. I reinstalled the patched LGUP. I put the phone in DL mode connected and launched LGUP. A step forward! I tried the LG update with the H933 bin and it failed. I noted your reference to DL Partition above and switched to that with select all. It indicated success, but the device was in a boot loop, with the android guy flashing very briefly. I forced a master reset and it appears to be booting into the first time setup process. Restoring backed up files and data now.
@ChazzMatt
Ugh... As I said before, 1 step forward two steps back. I have lost mobile data connection in the process.
Tried so far:
Verify mobile data is on
Verify roaming data is on
Verify no data limits or data saver on
Verify Network mode is correct - GSM/WCDMA/LTE
Verified I am connected with good signal to the home network
Master reset
Network Setting reset
APN verification. Reset to default. Recheck they are what the carrier expects
Text to carrier for auto setup files (40001 - SIM and 41111 - setup)
Carrier tech support advised they have reset my network provisioning on their side
Tried another SIM card from the same carrier - Still no data connection.
I remember someone else posting about losing their data connection after flashing back to H933 or maybe just the modem. I will search for that but if anyone knows what to do or can point me to it that would be great.
Next Question: How do I go about relocking the bootloader on the H933? I'm only familiar with the fastboot oem lock command, but I don't think that will work? I'm wondering if I need to be flashing back to H998, relocking and then back to H933 again?
Once again, thanks for the help

I would look through here some good information about going back to H933. You would have to go back to firmware with fastboot commands if you want to relock your bootloader. But unless your selling it or returnkng for warranty purposes no real reason to relock.

Thanks! took a while to get it, but it worked eventually.
I don't know if this is the place to post this, but does anyone know if we can rollback to this firmware from the September 2018 H933 update without causing issues?
From what I'm reading, it shouldn't be a problem as when booting from download mode, we are essentially telling the phone it doesn't have firmware installed and to install the firmware we tell it to, correct?

[Guide] How to recover from "This phone is permanently locked and cannot be unlocked"
The story:
So I have a V30+ with AS998 carrier, then I Frankenstein it to US998 and unlock bootloader and flash TWRP and all is good. But the signal is pretty bad since I live in South East Asia. Then I tried to flash the H930 OpenEU 21A zip rom from westwood 24. Well, it boot fine but i have no service after tapering around for many method (which many said the only solution is to send it back), I tried the"2945#*930# and the sim unlock screen says ""This phone is permanently locked and cannot be unlocked"". I tried flash back the Us998 kdz by LGUp, same message, flash the AS998 kdz also same message and no service
So I wrote this for anyone later encounter this problem
tl;dr
The solution is rather simple: flash back to nougat stock us998 kdz via dl parition in LGUP then back to oreo US998. :good:

Thanks for the tutorial.
I know it's been a few years already, but do you remember did you tick all partitions (select all) or exclude any of them?

[Guide] How to recover from "This phone is permanently locked and cannot be unlocked"
The story:
So I have a V30+ with AS998 carrier, then I Frankenstein it to US998 and unlock bootloader and flash TWRP and all is good. But the signal is pretty bad since I live in South East Asia. Then I tried to flash the H930 OpenEU 21A zip rom from westwood 24. Well, it boot fine but i have no service after tapering around for many method (which many said the only solution is to send it back), I tried the"2945#*930# and the sim unlock screen says ""This phone is permanently locked and cannot be unlocked"". I tried flash back the Us998 kdz by LGUp, same message, flash the AS998 kdz also same message and no service
So I wrote this for anyone later encounter this problem
tl;dr

I want to root an LG g4, the bootloader and/or recovery seem to be missing from the device. Purchased used off ebay. Is the LG LS991 [H811] Model (Sprint) (also seller claimed its unlocked and that seems to be so when i tested my sim). I can only get the phone into download mode, so when i check it with SALT I see the antirollback says "40". I heard the term frankenstine device thrown around before. IS it even possible to root this phone anymore? IS it possible to get access to the bootloader? I feel like i've been walking around in the dark for a while. I would greatly appreciate any advice

In SALT switch to develop mode (SALT thread FAQ tells how) and then check the ARB again

Hi, I've got a similar issue. US991 bought new 2017 from LG via newegg. Advertised unlocked, assumed that just meant carrier unlocked, which it is, but also has OEM unlock flag in developer options. LGMENU shows ARB=2 but SALT stable shows ARB=20 so won't flash USU. SALT develop mode shows ARB=2.
Do I USU from develop mode? Does this one need USU (have never tried to flash TWRP or root or anything. Any help/guidance is welcome. the MM LG pushed to it in 2017 doesn't have firmware support for VOLTE which i was hoping to get by flashing a new ROM since i have have no calling since the AT&T 3G shutdowm.

only H811 does NOT need UsU. The h815 can be unlocked as well but only when you have the unlock bin already as the LG website closed. so: yes you need UsU.
yes keep SALT on develop and flash UsU there. The good thing is that FAQ #1 applies to your device so you could even go back if something is not working as you want it.
Thanks for your help steadfasterX.
US991_UsU_unlock.zip in develop mode worked great.
twrp-3.5.2_9-PREVIEW-275_g4.img worked great.
however, i have a new issue. when i flashed US991_UsU_baseband_flash-in-twrp.zip my SIM is no longer recognized; mobile data can't be enabled, says connection not allowed so can't add an APN. LGMENU shows normal APNs (ATTPHONE, NEXTGENPHONE, etc are gone). has a couple prepay APNs listed that i don't recognize and can't edit thru LGMENU. SALT GPT is H811 which i thought was just for the ROMs. do i need to actually flash H811 basebands? or just flash one of your H811 ROMs like lineage 18.1? not sure how to fix this. again, any help/guidance is much appreciated.

well there are 2 problems here:
1. not many us991 users here so less user feedback
2. usually no one wants to stay stock so less user feedback
the main problem is that the baseband files are incompatible with your bootloader stack (hopefully its just that). a fix for that would be creating a new baseband flash file from your modem partition. pls provide it from your backup BEFORE using UsU and I can take a look
