Guys, Is there any way to get rid of that ugly bootloader unlock warning when phone is reboot?
EDIT September 11, 2020:
Here you go:
LG V30 Unlocked Bootloader Warning Disabler
I would add it to the WTF Instructions but I've run out of room on that LONG post. It's posted in the mods/themes/apps section. People will just have to find it.
Thats the bootloader, telling you its unlocked.... thats before/during the splash screen i think...
I doubt we can get rid of it, except locking your bootloader again probably? (is that even possible on a H930/US998?)
No,like on the G5 it's not possible to remove it.
Unlocked bootloader = warning screen.
There is nothing we can do.

On my old Moto G was the similar bootloader unlock warrning and someone made the flashable zip that this turn, off but that was message instead of the Motorola logo. This was annoying for everyone.

Bootloader unlock warning has always been able to be replaced on Motorola phones. It's simply a static boot logo graphic.
When you unlock a Motorola bootloader, the "regular" M logo gets replaced by a scary "bootloader unlocked warning". Both are simple static graphic files. I've made lots of them for Motorola phones, which could be flashed via ADB or even TWRP. Surely LG is the same?
What do people do for the bootloader unlocked open market LG G5, V20, LG G6? They don't put up with that annoyance do they?
I suppose if the image the bootloader draws for a short time over the splash screen is stored somewhere else than the bootloader itself (aka not hardcoded), im sure it could be replaced, but someone has to find out where its stored how xD

Yes, on some phones it's called the splash screen. Also, called the boot logo, not to be confused with the boot animation.
Surely people have done it. I've not messed with LG phones since LG G2/G3 and then I never really unlocked the bootloader but used exploits to install TWRP and root. But it's common with Motorola phones.
If you want to figure out the format of the raw_resources partition, that is where all the images are stored. It is possible to change them, but if you mess up, then your phone is a brick since abl will not load -- which is why the risk just wasn't worth it for me.
They are RLE so they have no header. There is an index that gives the name and offset for the location of the image, but not the size (either they are all the same size, or the size is stored somewhere else).

What if you just want a different boot animation?
Is replacing the Zips in system - media safe?
Or just out right delete them? I hate that T-Mobile logo with a passion.

Edit, I figured it was safe but to be sure I tested on my V20.
Now I customized my v30 .
Perhaps better yet (though I need some more people to help confirm this)...
I have successfully removed the bootloader warning for my unlocked US998.
The process is simple but try at your own risk for other variants more dissimilar to the US998 etc.. etc..
Steps:
Verizon (in their infinite wisdom) thought "Oh hey, no one will ever ever ever get the LG V30 with our software and have an unlocked bootloader, so why even bother having an unlock warning. "
Lets prove them wrong.
Take a backup (of course)
Go grab yourself the latest VS996_20d kdz file (available here on XDA or "LG-Firmwares")
Get your phone in LGUP mode (/w power off hold Vol-UP while inserting USB to computer)
In LGUP select PARTITION-DL and point it to the shiny VS996-20d kdz you waited so long for the download to complete
Click start then in the partitions list ONLY select raw_resources.
Click Ok.
The phone will do its thing and it will reboot and you will notice a black screen instead of annoying warning... Thanks Verizon. :silly:
Hope this helps!
That warning screen is nothing to even care about.

It does get rid of the bootloader unlock warning, yes. However it now says you have a V30, even if you have a V30+. Depends on if that matters to you.
If someone has a phone under warranty and wants to be really brave -- null out raw_resources and you should just have a black screen.
Again, that is a risk since the loading routine in abl could have bugs and get wigged out and go into a loop or something. If that happens -- 9008 brick.
If someone wants to try it, boot to TWRP and:
Code:
adb shell dd if=/dev/zero of=/dev/block/bootdevice/by-name/raw_resources
reboot and tell us what happened
-- Brian
I thought about this because I liked customizing the boot on my old Motorola phones.
But then I thought, how many times do I actually restart my phone to care about how the boot screen looks?
95% of the time, your phone is on standby.
LOL @runningnak3d ^
Considering you can no longer decompile abl since it is encrypted, the only way to find out is to test it
-- Brian
I'd like to, but this phone as of Saturday, is still worth nearly 500 in-store trade. I'm on the fence.
I can tell you that the only thing in raw_resources are the images that you see for things like the big errors and the charging images, and crap like that.
Someone has to do it. I would, but for some reason eBay doesn't want me to have a V30 .. they just want to tie up my money.

I think I'd rather take my chances poking around in the binary with a hex editor before zeroing the whole partition. Zeroing would be asking for null pointer exceptions in your bootloader. I don't want to speculate what that might do. Who knows with LG... maybe it will re-lock the bootloader bahhaha....
As others have pointed out i'm not sure the reward is worth the time right now. There are a lot bigger problems yet to be solved with this device in terms of development.
Hello, I just got a used V30 US998 from B&H Photo, my first LG phone. I tried to unlock the bootloader but when I reboot into bootloader I get this screen that says Welcome to fastboot for bootloader unlock (image bellow) but no fastboot commands work and the only options I have with the volume buttons are RESTART or POWER OFF. I am I missing something? has anyone come across this? So far I tried a hard reset, I flashed the oem rom with LGUP with no luck. Any Help or insight would be greatly appreciated.

It could be a used US cellular us998. The us cellular version does not have a unlockable bootloader like the open market us998.

How are you trying to unlock the bootloader? You have to flash the unlock.bin file given to you by the LG Developer Bootloader Unlock list, after you've entered the IMEI and DEVICE-ID (and it was verified as being eligible) after you've created an LG developer account.
Have you done all that?
You can't just walk up to the phone and OEM unlock the bootloader.
From that screen you're on in your picture, you flash the unlock.bin file with a fastboot flash command.

B&H Photo wouldn't sell used U.S.Cellular model phone.
I can't tell if he says he bought it from B&H Photo directly, or the person he bought it from claims they bought it from B&H Photo?
If the latter, does he have any proof from the seller it's actually from B&H Photo? If he bought it himself from there, then he knows for sure.

Thank you for the replies. To clarify your legit questions, I bought the phone directly from B&H and even called LG to confirm it is an unlocked open market US998 and is under warranty. I've always had HTC phones and always unlocked and rooted them etc... LG is new to me but I am somewhat familiar with the process bootloader unlock is very similar to HTC. Back to the bootloader issue yes I did everything you mentioned other then getting the unlock code Bin file from LG because I can't get the device-ID from the phone since it wont go into fastboot mode it wont do anything when I issue fastbood commands in that screen. and yes I read everything I can read about doing this and tried everything I can think of, but of course I can't think of everything! it could be a very simple thing I am missing. I read somewhere that, that screen is a debug bootloader. also when I reboot into recovery using ADB command it says "NO COMMANDS HERE" if I remember correctly. it's very frustrating when you can't void the warranty on your phone!!! Again I appreciate the responses.

Problem solved. The issue was a missing driver in windows 7. I am attaching the driver in case anyone runs into the same problem just double click "install.exe" after extracting the zip then connect the phone reboot into bootloader and you should see Fastboot in device manager, now Fastboot commands should work. Thanks to everyone that responded.
Just want to say that this is the ONLY answer that worked for me, out of countless pages of irrelevant or bad advice. The file above will fix the "Other devices: Android" missing device when in fastboot mode on Windows 7. Fastboot will then see your LG-V30.

WTF Troubleshooting Tip #7.
No need to go through countless pages of irrelevant or bad advice. . Glad you found it, but it's posted in the WTF INSTRUCTIONS Troubleshooting Tips for good reason. @FZZF is thanked there also.
Well yeah I guess that's true. Most of the bad advice was from across the Internet over there, not from here of course.
I'd suggest to always make it a habit of typing 'fastboot devices' or 'adb devices' whenever you connect the device to your pc.
If (either of) those commands don't respond with a listing of your device name / number... then the pc can't see the device. That's a
pc driver problem.
Cheers, keep it simple.
Hello everyone,
I want to unlock boot loader on my LG G PAD IV 8 (V533).
I did the OEM unlock in setting of developer options, But I couldn't reboot to bootloader and fastboot mode.
I tried:
1) adb reboot bootloader -> it reboots normally
2) Volume down and power and release power and hold all keys down --> IMEI display
3) Hold volume Up and connect USB --> Download mode (no fastboot)
4) Volume down and power and release power and hold back power --> factory reset
How can I enter to fastboot mode on this device so I can unlock the device? I don't find the key combination.
Thanks
Did you fimd any imfo on this yet???

Hi,
Looks like the Canadian variant of the LG GPad IV 8.0 is unrootable or unable to unlock the bootloader. However, the US T-Mobile variant (V530) which is essentially the same specs, is rootable according to other XDA post https://forum.xda-developers.com/g-pad-x-80/how-to/guide-root-lg-g-pad-v530-newbies-t3901485
Should any new info come up regarding this variant, feel free to post it here. Thanks
I just flashed 8.1 with a Korean kdz. onto an LG-V533 using LGUP Dual Mode. Next I will see about recovery, but for now pleased with the results. I got tired of searchig for American firmware with identical hardware.

Did you simply use the LGUP Dev mode and flash the Korean kdz onto the V533 or did you modify anything somehow? Would like to try it but not familiar with flashing LG devices, only ZTE and HTC
That's correct. I am going from memory here, but i know i did not make any alterations of any kind prior. It will repartition the device and i'm not certain if you can revert.
I did it for a friend and it works well. You'll wind up with a few weird Korean apps. The ones you can't uninstall just use adb or app manager.
I am pretty sure the selection i used was "download" and it gave a warning about repartitioning. So obviously i did it. I think it froze during initial boot. I recall waiting far too long and just force rebooted and all was well. I am much more comfortable flashing a Motorola or Samsung myself. I've cross flashed a few Lg's now and they seem to work well.
Even though i spend a lot of time making sure it can work, you may get different results. Make sure it's charged good. I learned that one already. Let me know how it goes!
After your cross-flash, 3g/lte works? Your IMEI remains the same as original IMEI?
Thanks.

Sorry. I did it and it was successful
By this do you mean your IMEI remained the same (original IMEI)?
I would like to cross-flash in order to unlock the bootloader, then install TWRP. Thank you. Could you give more details about
(1) Your original model. I assume it was LG-V533 Canada Rogers or Telus.
(2) After cross-flashing, the model changed to ...? Have you tried "adb reboot bootloader" . Inside bootloader: "flashboot oem unlock"?

I have no idea. I did it to upgrade the OS and my buddy never intended to put in a SIM. I will see if i can get him to check. Pretty sure his ex has it now. But i'll check out the imei if possible.

Hello
Does anyone have any active custom rom links/tutorials for V533 and V497? seems all online are down or gone? Thx
Hi,
I've searched for instructions but can't find my situation.
I'd like to unroot, go back to LG stock, and lock bootloader so I can sell my LGv30 US998.
I have the actual US998 from B&H (not one that's been converted from something else).
Current build is: US99820a with March 1, 2018 Security.
Can someone let me know the procedure? I believe I'd like to go to the latest Oreo version "h" I think.
PS. I've tried to install LGUP tool, LG Flash Tool and none of them seem to detect my phone on Windows 10 from https://lgflash.com/download/ There are so many versions of all of these programs I don't know which one is correct. I've also installed the LGMobileDriver_WHQL_Ver_4.5.0.exe
So, some links to LGUP that actually works would be great.
Thanks

follow instructions from ChazzMatt's thread, they have LG UP dual linked and the instructions to flash kdz
Thanks. He has lots of threads. Do you have a link?
I believe it's the one/main thread he maintains on how to root/unlock the phone. You'll have to do some thinking on how to go "backwards" from there, but the software and steps are all in there.
Generally speaking, it's NOT recommended to relock the BL because if the phone isn't 100% stock ROM, I believe you could end up bricking or bootlooping. I think you can leave the BL unlocked and just KDZ flash US998 and leave it unrooted (no Magisk, etc). This should look "stock" to anyone who cares to have a stock-specific phone anyway.
I'm concerned a buyer wouldn't like the opening "corruption. lock the bootloader" screen. My assumption is locking the bootloader would get rid of that... Does anyone know if that's true?

Yes, re-locking the bootloader will get rid of the warning screen. Just make sure you are 100% complete stock (all partitions) before you re-lock it. Otherwise the phone may brick itself.
Also, make sure you remove your Google account in the OS before you wipe/re-flash the phone. Otherwise it will trigger FRP and require the new user to enter the previous username and password.
I might be in the same boat here, would love to know how to just return to stock and relock bootloader (for someone who didn't make an initial backup)
How about these steps:
1) Make sure you have working ADB on your computer, including latest LG USB drivers.
2) Boot into the OS and remove your account using Settings -> General -> Accounts -> (select Google account) -> Remove account. This prevents Android's Factory reset Protection from kicking in, which otherwise would require the previous account to be re-entered after wiping the phone.
3) Go to ChazzMatt's US998 Pie KDZ thread and download and install LGUP exactly as described under How to Install Dev Patched LGUP towards the bottom of post #2. Remember to thank Chazz.
4) Download the KDZ for your current OS version (Oreo or Pie) either from the relevant KDZ ROM thread in the V30 ROM sub-forum or from LG-firmwares.com. Verify its MD5.
5) Enter Download mode: With the phone off, hold Vol Up, and plug in the USB cable that is connected to your PC.
6) Assuming you manage to get into Download mode, launch LGUP and make sure it detects the phone.
7) Flash the KDZ you downloaded using LGUP Refurbish mode. If you're on a custom ROM and/or if you want to do a particularly thorough job, you may consider FIRST flashing Nougat using LGUP Partition DL mode, THEN flashing back up to Oreo or Pie, again using Partition DL Mode.
8) After LGUP (hopefully) completes flashing the KDZ unplug the cable and let phone reboot.
9) Once (hopefully) you're booted into the OS, tap Settings -> General -> About phone -> Software info- > Build number until Developer Options are enabled.
10) Enable Settings -> General -> Developer Options -> Enable OEM unlock.
11) Turn phone off and unplug the cable.
12) With phone off, enter fastboot mode by holding Vol Down and plug in the USB cable that is connected to your PC.
13) In ADB window on computer, enter fastboot devices to verify ADB is working.
14) In ADB window, enter fastboot oem lock to re-lock the bootloader.
15) Use fastboot keys to reboot phone into OS. See that it works.
16). Run Settings -> General -> Reset -> Factory data reset. Do NOT use Master Reset (button dance) or the new user might trigger FRP/kill switch (although shouldn't happen if you removed the account previously and didn't enter it again).
17) Done. Hand off the phone to its new user.
These steps were written off the top of my head. If anybody sees glaring mistakes or omissions, then please let me know.
Note: Some carrier models cannot readily get into fastboot mode. For those you will need to convert back to stock US998 to re-lock the bootloader (using Frankenstein like when you first rooted) and THEN convert back to the carrier firmware (again using Frankenstein).
Thank you

7) Flash the KDZ you downloaded using LGUP Refurbish mode. If you're on a custom ROM and/or if you want to do a particularly thorough job, you may consider FIRST flashing Nougat using LGUP Partition DL mode, THEN flashing back up to Oreo or Pie, again using Partition DL Mode.
8) After LGUP (hopefully) completes flashing the KDZ unplug the cable and let phone reboot.
9) Once (hopefully) you're booted into the OS, tap Settings -> General -> About phone -> Software info- > Build number until Developer Options are enabled.
10) Enable Settings -> General -> Developer Options -> Enable OEM unlock.
11) Turn phone off and unplug the cable.
12) With phone off, enter fastboot mode by holding Vol Down and plug in the USB cable that is connected to your PC.
13) In ADB window on computer, enter fastboot devices to verify ADB is working.
14) In ADB window, enter fastboot oem lock to re-lock the bootloader.
15) Use fastboot keys to reboot phone into OS. See that it works.
16). Run Settings -> General -> Reset -> Factory data reset. Do NOT use Master Reset (button dance) or the new user might trigger FRP/kill switch (although shouldn't happen if you removed the account previously and didn't enter it again).
17) Done. Hand off the phone to its new user.
These steps were written off the top of my head. If anybody sees glaring mistakes or omissions, then please let me know.
Note: Some carrier models cannot readily get into fastboot mode. For those you will need to convert back to stock US998 to re-lock the bootloader (using Frankenstein like when you first rooted) and THEN convert back to the carrier firmware (again using Frankenstein).

not sure if you can help. i asked chaz as well but haven't received a resolution. i've done this but the phone at aroud >10 says that it needs to enable oem unlock to move forward with fastboot commands. except that this option is greyed out in the dev options. says phone is bootloader is already unlocked and doesn;t give option to enable it?? sigh i have tried 4 versions nougat and oreo ... none worked... any ideas??

I've heard of this before, where OEM Unlock was greyed out in the Developer Settings menu. I believe the answer was you have to wait a few days and it will change. But that's very frustrating when you're trying to get this phone back to stock.
Just to make sure I understood you correctly: You have tried booting into fastboot and run "fastboot oem lock" even with OEM Unlock greyed out, right? Otherwise definitely try that.
I am afraid I don't have any other suggestions.
@ChazzMatt: I remember you posting about this one time. Do you have more to add?

Understood. Question: Did you flash KDZ with Refurbish or Partition DL? Maybe one of them will clear this state and the other won't. But DON'T go experimenting with other LGUP modes!
Also, you could try a Factory reset and/or Master Reset (button dance) and see if that clears it.
If none of that works, you may have to just wait it out.
Edit: I googled around a bit. It seems Factory reset, then letting the OS connect to the internet (enable WiFi) can make the difference. Try googling as there are many references to this.

Why can't you wipe it and return it to VZ like that? They don't care if it's rooted, bl unlocked, etc. They're going to wipe it when they get it and try to resell it regardless, why do their job for them?

i read somewhere that rooting a phone violates their terms and makes it invalid as a trade in...

It voids whatever warranty existed between you, Verizon, and LG, but I haven't seen anything about trade ins. Where'd you read that?

Did you try a Factory reset from the menu, then setup phone again with WiFi enabled? Heck, possibly even entering you Google account during setup and let it sync, if that's what it takes. As long as you perform a Factory reset from the menu to remove your account before trading it in.
@ldeveraux is probably right that Verizon won't care. But I am cautious person too when it comes to these things, and would prefer to trade in the phone in a clean state. Just in case the person you end up dealing with is a nitpick.

i did try the factory reset. both from within and the buttons. and connected with wifi. didn't work... sadly. removing my account is not an issue. every time I install 1 of 4 diff nougat or oreo kdz in lgup, I put skip in the login so it doesn't have my info anymore... resetting doesn't really do it. messing with the date like others have suggested didn't either.

That is indeed puzzling. I did this twice on my old H932 before sending it in for warranty, and never saw that problem.
I am sorry I don't have more suggestions to offer
This phone was given to me by a friend, he says he got drunk, changed his lock code and doesn't remember. After a factory reset it just stays on a screen asking for a Tracfone SIM and he kept his SIM & moved halfway across the country.
I just wanna know if there is any means around this?
I called Tracfone, gave them the IMEI & they told me the phone will be eligible for unlock in about a month, I don't wanna wait as I can't root my S22 Ultra and I just wanna get back in the rooting scene, LOL
I know, call me impatient....
I apologize, I didn't notice a post w/ same issue but on a Cricket phone whereas mine is Tracfone but same situation.

What's the Model and build number? Is the bootloader locked or unlocked? Without knowing much detail I'd recommend finding the firmware that matches your phone and fastboot flash that or at least TWRP recovery if you can find one that works with yours and then you'd have more flexibility. This is all if your bootloader has been unlocked already though and if it hasn't I'd start looking through some threads on how to do that if you don't already know how to. If it's possible with your variant too I know carrier devices are pretty strict on unlocking the bootloader but Idk about tracphone variants.
It's not unlocked.
It's the Tracfone Moto G Power
Look up a thread here on xda about unlocking the bootloader for Motorola devices and come back here if you can unlock it. You'll have to do that before you can even flash anything such as partitions like a custom recovery.
