When I get into fastboot it clearly says lock state is unlocked. I got it there by using the lg cs tool to flash the v410 at&t version kdz. Then I unlocked through ffastboot there. I then used the lg tool to flash the vk410 kdz back to verizon. It seems to work fine just nothing available that i know of to flash to it to see if it works. But when I boot into fastboot it still says Im unlocked. If anybody has any ideas or knows where i could maybe find something to try and flash that would be cool thanks. Also I dont reccomend trying what I did unless your willing to brick your tablet. Just dont do it. Nothing I did was a good idea probably.

LAF NUKER wipes your Download mode and let you use Fastboot instead.:
Do this on your own responsibility, if you bricked your phone in some weird way then don't look at me.
But with this simple thing you can't brick your phone only if you flashed the wrong zip which wasn't from me.
This is more meant for developers/testers.

I was getting irritated that my Fastboot mode dissapeared everytime when I flashed some lollipop stock based rom as those all included bootloader files, so I had to first attempt to get into the rom itself or recovery to wipe it again over and over. So I thought by myself why won't I make something easy and flashable?
This lightweight flashable zip from 2-4KB is tested by me multiple times so after you flashed it I HIGHLYsuggest that you need to test or you can enter download mode and see if it shows now fastboot. If so then everything succeeded like it should, it has an succes rate of 100% as nothing could actually go wrong with this.
This script/method should also work for the G3 and some other LG devices which have this partition:
Code:
/dev/block/platform/msm_sdcc.1/by-name/laf
For the one's who care the shell script is located in the update-binary, updater-script is just dummy.
If you want to revert back, just flash the jb/kk/lp bootloader files.

My question is somewhat off-topic but I'm having a hard time understanding how bootloaders and ROMs work with the G3.
When I had a G2 I learned about the difference between Kitkat and Lollipop bootloaders the hard way when I tried to restore a Kitkat nandroid backup over stock lollipop and hard bricked the phone. My impression was that since the KK backup did not include a compatible bootloader I needed to flash one or restore to stock KK.
Now you are suggesting that ROMs for the G3 *include* bootloaders, which is news to me. Does this mean I can go back and forth between Kitkat and Lollipop ROMs without worrying about bootloaders? Or restore nandroid backups without the same concern? I don't want to have to downgrade to Kitkat every time I want to try a new ROM or restore a backup.
Thanks.
No most roms don't include bootloaders but some stock roms do, especially in the g2 community as I made this first for G2 but I also found out that it would also work on the G3. I guess g3 is the same as the G2 in terms of flashing. Lollipop stock roms need lollipop bootloader related files to properly boot but the bootloader is from kitkat with the g3 because else bump and flashing doesnt work. Only on the g3 tmobile version as that version has an unlocked bootloader. Just read the op's from the threads good and you will know what you need to flash here in the g3 community. But download mode might not always properly work as solution I have this laf nuker so you can flash the good kernel and or recovery if you softbricked your phone. If you hardbrick your G3 you can still fix it as far as I know so don't worry.

I have the T-Mobile version of the G3. How does that make things different?
It cost me $45 to fix a hard brick on a G2 which I later found out was still under financing with T-Mobile so I returned it. It was an expensive little device.

Well as far as I know the t mobile version has an unlocked bootloader so more freedom for flashers. I also hard bricked my G2 but before I hard bricked it there was a shortening method guide on how to hard unbrick your g2. Could also work on the g3 perhaps. Well that sucks that you needed to pay $45 lets just hope for you that it won't happen again.
If you want 100% clarification about the bootloader and different roms then you might want to ask it in the Q&A or a rom thread as I am a G2 user. But short story as far as I know. Lollipop bootloader related files for lollipop stock roms. And kitkat bootloader related files for custom aosp roms like euphoria cyanogenmod etc.
I don't know if the guy I paid (who fixed it the day he got it so it couldn't have been so hard for him) had to open it to short the pins but after watching a video showing it done I wasn't going to chance it. It was like repairing a watch. Plus I tried the sw method of viewing the borked partitions in Linux and then replacing them but I couldn't see them to replace so I paid for the repair. And I only had the damn phone for a month before I discovered the problem with T-Mobile and sent it back.
I must say the G2 was a *very* finicky device compared to the Optimus G Pro I had before. And that phone never worked properly with any AOSP ROM. I don't know why I'm so loyal to LG. Must be because the phones are cheaper and I really don't like Samsung any more.
Of course the Verizon Motorola Droid Ultra I bought for my wife used is even worse. It's completely locked down. You can't root Lollipop on it and you can't downgrade to Kitkat once you've taken the OTA update.
Until somebody can explain switching ROMs on the G3 to me like I'm five I think I'm just going to always go back to stock Kitkat, re-root and re-install TWRP. Seems the safest thing to do.
Hey guys just picked up this phone after it looked like it had root and a unlockable bootloader.
However it seems that we are in the same boat as the tmo g5 unlockable bootloader, but no fastboot/ boot/flash commands seem to work.
(just tried to flash the 428 metro twrp to try to get supersu.)
how it was fixed on the g5 was flashing a custom tot with LGUP the had twrp built into it.
waited three months on that phone for root. I really don't wanna have to fall back to it. as it has pretty bad image burn from my trying to flash a deodexed rom. Long story. I'm willing to try to help anyway I can. At this point I don't care if it gets bricked. phone is useless to me with only 8 gigs of storage. if anyone could get a tot or possibly kdz file. maybe @tungkick could help us out like with the g5?
Unless anyone else has any ideas. I'll continue to help but I'll prob try to pull $275 outta thin air and upgrade to the v10 next friday.

What is it for?
Wouldnt recommend unless you want to test risk it. Its a kdz so format is right but its not for the us region.
This is a nice way to brick.
Cross-flashing radios, and/or bootloaders = GG

I tried it and now I am on a island by myself. I got service, made a phone call and got text. It run through about every service possible and then dropped them all!!! It was such a kick in the ballz. Come swim with me the water great!
h910pr
i can confirm i have flashed the h910pr rom to my att h910 and it worked fine for me. stuck on the claro software but its actually better than atts lol. maybe someone could work on this firmware version since we have a kdz of it.
@predheadtx I don't suppose you checked to see if someone was asleep at the wheel and left fastboot oem unlock wide open?
Not sure.

I was originally on the h910 att firmware, then used dirty santa to open the bootloader and root. I found a rom that i really like and ran fast as heck, but it wouldn't sync with my watch. I tried a factory reset with led me to a twrp boot loop and nothing i did would get me out of it. so i tried to reflash twrp and it led me to a bricked phone that wouldn't power on past the boot loader unlocked notification. After tons of research and a little tweaking to a few things i got lgup to recognize my phone and flash the h910pr kdz to my phone. if anyone needs i can make a zip of the tools i used and post it somewhere.
edit- uploading to mega right now. will post a link in a little bit to a zip with my lgup folder configured exactly as it needed. install lgup2016 and the lg drivers then copy the lgup from this zip over the lgup folder in your programfiles(x86). essentially all you really need here is the lgup_common.dll which is actually just the h918.dll with the name changed. i had read the fccid's on the h910,h910pr and the h918 were the same, which meant by a measurable standard they are the same hardware. so i took the assumption the dlls would be compatable. by pure blind luck with the folder layout as shown in the zip and the kdz included as well it took. i was a little worried because i had read someone tried this and could not get carrier service. i thought id at least make the phone usable in case a fix was found.my phone reports itself as an h910pr now but is connected to the att network with no issues, text, talk and web all work fine as well as att services.
I had checked a while back and saw that the h910 and h918 had the same FCC ID, which, as you stated, means they have to be the same hardware. I am using my h910 on T-Mobile, so now that I know (if it fails for some reason) that I can flash the h910pr KDZ, I am going to try the h918.
Sorry that you almost had a brick, but thanks so much for verifying that this works.
hi to everyone concerned, i have begun monitoring this thread;
https://forum.xda-developers.com/v20/help/lg-v20-h910-kdz-t3612524/page2#post72599368
please direct any inquiry's to my experience there. there is also a link and directions there to restore any bricked lgh910 to the h910pr version, as well as development on using the h915 and h918 firmware.
This is my first post here at xda so sorry if this is in the wrong section or something. Will move / edit / anything that needs to be done
Okay. I've really messed up my V20. It was originally an LS997, but now TWRP and ADB say the model number as a US996. I don't really understand that, but it happened. (I also know it is supposed to be an LS997 because I can't get a bootloader unlock key from LG. I have no idea how it was switched.)
I've installed a few different 997 and 996 roms and both work. Even with a 997 rom ADB says it is a 996 so yeah.
Here's my other problem: the phone seems to have broken itself when it comes to cellular data. When I first rooted it and got a rom installed (i forgot which, probably a stock deodexed one) my service worked but data didnt. Now on every single rom i install, no service is there at all, and with one of the roms, its on the 'LG' network.
so, basically I just want to have a working phone. At this point I don't care if I have to go to stock with no root to have the phone work.
Here's what I would like to see if I can do
- get the phone back to LS997. The sticker and LG says it is, but the phone says it is a 996.
- get my cell data working. I've read somewhere that I have to flash a modem with hboot or something but I don't know what to flash or what hboot is (what is it?)
but really, any help is appreciated. I'm new to this, but really techy, so I can figure out basically whatever y'all tell me to do
okay, so after writting this I realize I might want to say how I got in this mess: a few days ago I followed the wrong tutorial to root my phone and now we're here. (it was a V20 tut, but LS997 wasnt supported.)
I use Sprint too if that helps.
I've also tried to flash the Stock_LS997_Full.zip but ADB fails to read it every time. Also the Classic ZV7 for LS997 flashes but fails becuase "This phone is 996 and this rom is for 997" or whatever somthing like that.
I soft bricked my phone a year ago, now I'm trying to bring it back from the dead.
The sticker on the case says that it's an H910 model; purchased refurbished I'm almost certain that the actual hardware is an H996.
In any case, I used LG UP to get a fresh KDZ install of the H915 image onto the phone. Sound, camera , and microphone, honestly I bet there is more there that doesn't work but for now that's all I can name.
I want to unlock the bootloader so this time around instead of using Dirty Santa I'm going the official route.
Problem is that in order to get the Device-ID I need to get into bootloader mode. For now it looks like I'm not able to do that.
Every time I run the
Code:
adb reboot bootloader
command I get the device to only restart.
Any general help is appreciated.:good::laugh:
Not sure where I'm going to go with this phone, honestly I need this thing to be more then a paper weight for me. Literally haven't had a working cellphone in more then a year and it's not working for me. I think I'm just going to keep a stock ROM with root, that's about it.
