A little ways ago, I bought an unlocked LS998, which was converted to US998 via the Frankenstein method. I thought to try the installation of a custom ROM (A.I.S., if it helps), but after failing to get that working, I reverted to a TWRP backup I made prior to the install. Now however, the phone kicks me a warning that "The Phone is Permanently Locked and Cannot Be Unlocked", which I can't for the life of me figure out. Is there a way to restore the old functionality?

Thanks for the tip--I did have to use that initially to get back into my phone, but the lock I'm talking about is on using my SIM card (confirmed good by my carrier, and which works perfectly if put into another unlocked device).
Well--bit the bullet, deleted EVERYTHING and flashed the latest firmware. Problem seems to be resolved!

Do forgive me if my memory is a tad hazy, as I've since switched phones, but from what I recall, I wiped out every trace of everything from TWRP, flashed a stock, factory image, and in one fell swoop the device was working good as new once more.

Hi,
I tried to install MARSHMALLOW on my XT1528 without unlock the bootloader and now got stuck on Flash Mode screen.
"XT1521_SURNIA_RETASIA_DS_6.0_MPI24.65-39_cid7_subsidy-DEFAULT_CFC.xml"
Later I realized that I cant unlock the bootloader of verizon mobile.
I have tried to install
"XT1528_SURNIA_VERIZON_5.1_LPI23.29-17.5_cid2_subsidy-DEFAULT_CFC.xml"
and got a error message "version downgraded for primary_gpt"
I also tried verizon software repair assistant.
Is there anything I could do to boot into my mobile?
Awaiting your assistance
I did the same thing several weeks ago, and posted warning people not to do it. Sorry, we're screwed.

did you find any way to make the device usable?
There are two versions of firmware for XT1528, one marked LPI23.29-17 and LPI23.29-17.5. It may seem like a negligible thing but if a device works with one then it won't work on the other. Try flashing both and hopefully one will work, that's you're best option

I am on tmobile lg g5, twrp installed, unlocked bootloader, rooted, running fulmics. I am returning the phone since the gps issues are becoming worse, and it has even started dropping cell service almost hourly which requires me to reboot. Can I completely restore to stock via flashing in twrp? Trying to avoid having to drive somewhere and use LGUP on a windows PC as I don't own one. Will the bootloader automatically relock if I flash the stock rom without flashing SU along with it? Appreciate any help.

There are stock ROMs (H83020a and H83020c) available to flash from twrp. You will not lock your bootloader nor lose twrp; but in order to get root again(in case you want), you will need to flash su. It worked​ for me perfectly and I have no issues with anything on my phone. The only thing that does not work (check screenshot for details) is google pay because since the phone is rooted "it does not meet the google's security standards." Now if you want to return the phone to factory state I believe there are threads here for that. If you still want to keep the phone just flash the appropriate zip and enjoy removing tmobile bloatware if you wish.

Ok. If you're wanting to do 100% stock, download the complete zip for 20c from http://downloads.codefi.re/autoprime/LG/LG_G5/H830/H83020c/LG-H83020c-Flashable.COMPLETE-ARB01.zip there. Put it on your extsd card. Backup everything that is on your internal sd (phone memory) like pictures, videos, SMS, etc. Once you've done that, boot to TWRP. Once in TWRP wipe everything except externalsd card, I also recommend using the format option to format the internal sd. Once you've wiped and preferably formatted data go to install and install the 20c complete zip you put on your extsd card. After it's done installing just reboot. This will overwrite TWRP and you will NOT have root. Your bootloader will still be unlocked though, so you still need a PC to relock your bootloader. Also I don't think encryption will be re enabled unless you flash the kdz though. Anyways that's your best way to return to stock without using PC.

I don't remember very well; but I believe it's hard brick. When I was researching to root my phone y read that somewhere, maybe here. I'll try to find the info on my PC when I get home.
Update:
I found the link. The advice is in the FAQ. Not sure if that would happen in your case since you have a custom ROM. The danger is when downgrading from H83010D to H83010A.

Thanks bro. I totally believe it because past phones had exact issue.
Sent from my LGE LG-H830 using XDA Labs
Just for clarification, if you're on Android 7, you can not downgrade to Android 6 without first downgrading your bootloader as it won't flash correctly. Also just something to always keep in mind with LG phone's at least, is that LG uses a antirollback system. Never attempt to downgrade from a higher ARB # to a lower ARB #, if you're somehow successful it will lead to a hard brick. Every firmware that autoprime has posted states what antirollback number it is on, so always check that. On h830, every firmware since 10D has been ARB01, only 10A or earlier was ARB0. While lgup shouldn't allow you to flash (should error out), no reason to take that chance. Hopefully that helps clarify
So I figured I'd go ahead and root my phone and the install went smooth. I got cocky and installed boombox, lost network. After a day of running stock root, last night I tried AOSP Extended. I got the ARM64 8.1 GAPPS. First attempt, it would just bootloop. Second attempt I made it to the setup screen, once I clicked next on wifi menu, it rebooted. I made it to fingerprint and it rebooted. Third try, I just skipped fingerprint and menu stated one more sec or something like that...rebooted. Is there any confirmed working roms for Verizon or should I just give up? Late last night gave up and hoped on LGUP, upgraded, and somehow the phone kept locking up, rebooting,no network, a mess. So flashed first Nougat dl partition, rebooted,setup. flashed oreo,upgrade mode,installed the 3 files, checked root and it worked. installed ifont and it worked so thought i was good to go and went to bed. Got to work today and installed substratum theme and system.ui hit and all I can do now is see my lockscreen clock, or long press to reboot. This isn't going as planned and not sure what I'm doing wrong. What should I do now? Reflash Nougat DL partition, flash oreo upgrade and I should be back to normal? I could never get adaway to work right so wondering if trying different roms worth it at this point after so many fails.
You using an exfat sdcard by chance?
that driver is a little diva... even though the same as in twrp for example, it somehow sometimes (often, not always) makes the system slow down and reboot for unknown reasons
try to remove sdcard and try again. maybe backup your sdcard and change the filesystem to ntfs or so....
PS: same build (just tried in a morning, later same day afternoon) worked, and later didnt work anymore and ****ed up.
Idk whats wrong there. Exfat is proprietary anyway....
Of all things I tried, I never thought about the sd card. When I get home I'll check, I'm hoping this will be it so I can try your AospExtended port. Thanks for the suggestion, I'll give that a shot!
It was exfat. I formatted into NTFS, rebooted. It gave me a warning sd card damaged, would I like to fix it or something to that effect. I clicked yes and installed DotOS with no issues. Thanks for your suggestion, feels great to rock some AOSP like old times! I might give Extended a shot, but this one has everything I'd need. Ran it all day today and no hiccup, everything is running like it should.

Actually he changed his VS996 to a US998 via the Frankenstein Phone method.

He rooted the US998. Same physical device - different firmware.
Yes, the US998 works on Verizon.

Every V30/V30+/V30S on the planet -- except for the T-Mobile H932 -- can be bootloader unlocked and rooted.
If you use Verizon, you can add back Verizon Wi-Fi calling and VoLTE after bootloader unlock and root.

Hopefully one of the Verizon guys will answer on how to do it. I'm not involved in the details for adding back carrier features. But I'm pretty sure I saw mention of Verizon Wi-Fi calling and VoLTE in one or more posts.
Sprint guys are helping the Sprint guys. @JWnSC started a thread specifically for them.
Korean guys made a video and started a thread to help the Korean carrier variants.

Hi XDA haven't been on here for a while.
So I have a question I was given a S9+ from Sprint it's unlocked I'm currently using it on TMO but I don't have wifi calling nor video calling. I wanted to see if it was possible to flash a TMO firmware. Since it's still on July's patch here's a screen shoot of current firmware.
I moved from Sprint to Tmo, and just put in the sim and then updated the firmware through the system update interface. All works as expected.
The difference may (or may not) be, if the phone was unlocked by Sprint or by another method. My wife's phone was unlocked via "another method" and cannot get it to update system software. I haven't bothered looking into it further though, as we don't expect to keep the S9+ too much longer.

Yes mine was unlocked different method so it won't update normally.
That's why I asked if I could cross flash to TMO

if your phone is unlocked via whatever method, it wont interfere with system updates. OTAs will happen at regular intervals based on the firmware flashed on the phone and the recovery status. Stock recovery means that youll get OTAs, if youre not, its likely a glitch and has nothing to do with the unlock status.
If youre looking to get your phone working on tmob and its a spr phone, all you really need to do is unlock it, put the new sim in it and configure the APN. If you want full features like voLTE and wifi calling, then youll need to flash a tmob firmware version on your phone which requires the patched version of Odin. I have a Cricket branded (originally, at least) S9 and i flashed the U1 firmware on it via patched Odin and the phone now thinks its a factory unlocked S9, as i also unlocked it via "alternative methods". Perfectly seamless transition and i get OTAs all the time

Hi,
I tried to upgrade my US998 from Oreo to Pie using LGUP patched. The upgrade process went well until the phone restarted and have this error message:
"Your device has failed a routine safety check and will not boot..."
I did try using LG Bridge to fix = not working
I did try fastboot boot laf.img (using extracted laf from H93031a_00_OPEN_EU_OP_1105) not working.
Any other solution?
Thanks
This Post got recommended to me. I am a Samsung user so my answer will probably be very stupid.
If you have fastboot, why don't you flash a recovery and a custom rom? Ik stupid but it's the only thing that comes to my mind since i don't have a LG phone lol

Ah ok so now I understand.
But why don't you unlock your bootloader then if fastboot works? Do you know for sure that TWRP doesn't work?

Unfortunately my LG V30 is US region. The official bootloader site not support my phone. Thanks for your info anyway
I'm not sure why a Samsung user was recommended this post. And no offense to the Samsung user, but the process for unlocking, etc is VERY different for Samsung than it is for LG... so I recommend not worrying about that. Believe me, I know, because I'm researching switching to a Samsung in the future, and the process is very different!
That being said, the best resource here is the WTF thread with the post by ChazzMatt. That post has everything you need in one place.
jacoozie, the error you're getting indicates that you had a non-stock phone when you flashed the KDZ on an unlocked phone. For this reason, it's no surprise you got this error - the phone must be COMPLETELY STOCK for a stock KDZ flash. I'm guessing you had TWRP or something else installed, which is causing this problem. Once you unlock, you cannot just flash things willy nilly... and generally you don't flash with KDZ unless you're trying to change models (aka Frankenstein) or on the way to a custom ROM.
It sounds like you've done some unlocking rooting... if so, I recommend you start over with the WTF thread, read it VERY CAREFULLY and ENTIRELY and then reflash as instructed there. I'm guessing you may need to go back to KDZ Nougat and then work your way forward. If you have questions, ask in that thread... but you shouldn't have any questions as the thread is VERY complete (been updated all the time with very detailed information, so everything is in there).

I didnt install TWRP or any recovery tools to my phone. My phone bootloader still locked thou.
I have read the WTF thread but the problem is I cant get into my Download mode.
Ok, what steps are you using to try to get into download mode? Presumably turning off the phone, then holding the volume up button and plugging in the USB cable (other end already connected to a Windows computer), correct? If that doesn't work, can you try other USB cables? Sometimes a bad cable could prevent the phone from going into download mode.
