Did you try turning it on and off again? :P

We need a little humor aha. I was waiting in DL too. I feel like it wants to flash everything and ignore what WE select.
[LG V20 Guides, News, & Discussion] runningnak3d:
Yea, something is wrong. Grab your H932 KDZ and flash the whole thing.

-- Brian
[LG V20 Guides, News, & Discussion] Josh McGrath:
Okay, I will flash back to stock. I dont get it. I only selected LAF and it says its writing all the others? Maybe it isnt really writing the other partitions?
[LG V20 Guides, News, & Discussion] runningnak3d:
Of I am sure that it is. Probably a safety mechanism in LG UP. At least we know it accepts the SIGN payload, so laf can be flashed.

A much safer route to find out if the V20 laf will boot is to find someone with an unlocked US998 that will do a fastboot boot laf.img that way it doesn't even have to be flashed. If it will boot on a US998, then it will boot on an H932.

-- Brian
[LG V20 Guides, News, & Discussion] Josh McGrath:
Well I guess it wasnt all for nothing at least. I believe [MENTION=3250376]ChazzMatt[/MENTION] has the US998???

On the bright side, I only flashed laf laf.bak and system (thats when I pulled the cord out) and still have my data and booted up fine
[LG V20 Guides, News, & Discussion] draymond1987:
Hmm, can't we do that on our devices? I think that if we try fastboot flash, that we KNOW only the laf is being sent over.

I was looking into that last night, but I literally could not figure out how to extract the laf.img .

I downloaded python and everything, and just got too frustrated with it. I didn't want to bug anybody to do it for me.
[LG V20 Guides, News, & Discussion] johnmurrayvi:
Interestingly, as discussed about the AT commands and qfuses, it looks like the V30 LAF also has references to blowing qfuses. I wonder if LAF does have write access to qfprom on newer devices.

Just figured it out a little while ago unfortunately. Believe me, I'll never buy another LG... I got the carrier-unlocked V30+ specifically to unlock the bootloader & root... I wish my G3 was the last LG I bought, instead of this unused paper weight. Can't even remove the pre-installed (in /system/priv-app) facebook apps. Disabling doesn't deal prevent it from receiving broadcast intents or the fact that it's in priv-app for god knows what reason, on a carrier-unlocked phone no less.

I just gat a notification to updated H918 from tmobile but i check the website and say still 10s im in 10s something is up
[LG V20 Guides, News, & Discussion] Josh McGrath:
Its probably Oreo, unless you havent updated in a while.

---------- Post added at 12:37 AM ---------- Previous post was at 12:36 AM ----------

LG also cut the nuts off the fastboot boot command. Im with you, python is confusing as hell to me. Its very unforgiving
[LG V20 Guides, News, & Discussion] draymond1987:
Is that why I got errors when I tried flashing TWRP, for the giggles? This was after I flashed that file, which, I still think did nothing at all. My phone hasn't done anything out of the ordinary.
[LG V20 Guides, News, & Discussion] gavilan2010:
No im in latest firmware 10s base on the website but still i had an updated coming but the site dont show it.
[LG V20 Guides, News, & Discussion] Josh McGrath:
Im actually suprised it even did anything when you tried flashing twrp because it usually gives an "unknown command" error on FLASH. And LGUP just tells me that you cant flash individual partitions when I try to flash twrp.img

---------- Post added at 12:45 AM ---------- Previous post was at 12:41 AM ----------

@runningnak3d

I just thought about something. What about pulling the USB cord after writing LAF and laf.bak ? If it flashes system a little bit, we can always just flash system from the h932 kdz like I just did.
[LG V20 Guides, News, & Discussion] draymond1987:
Oh no, I got the unknown command. I just didn't know if it would reject laf too.
[LG V20 Guides, News, & Discussion] runningnak3d:
So an update...

G4 and V10 (any LG eMMC device) are solved, just need to update some code.

G5, V20, G6 with unlocked boot loaders are solved, just need to update some code.

V20 with locked boot loaders are still being worked on, but a solution should be coming soon.

V30 with unlocked boot loaders need to test booting of V20 or G6 laf.

-- Brian
[LG V20 Guides, News, & Discussion] draymond1987:
Can somebody kindly pull laf.img for me? Maybe me and Josh can try flashing it via LGUP and/or fastboot ?
[LG V20 Guides, News, & Discussion] runningnak3d:
[MENTION=5070414]Josh McGrath[/MENTION] very risky, but that should work.

When a flash happens, the last packet that is sent causes lafd to flush the buffer. So if you flash laf, and then flash H932 system, you should be good. System is broken up since it is so big, so if it starts to flash you have to flash the H932 system.

-- Brian
[LG V20 Guides, News, & Discussion] Josh McGrath:
Okay so this is probably well known to you, but flashing the laf and laf.bak is fast but the system is a slow write process so I'll have plenty of time to pull the cord, then immediately flash the h932kdz system only. (It let me just flash that unlike the v20 kdz)

But after it's complete, how would I know what laf version it is? I'm about to try that since there's such a large time gap to interrupt while writing v20 system

---------- Post added at 01:05 AM ---------- Previous post was at 01:03 AM ----------

Pulling laf.img wouldn't work for me. But even then it would be hard to find a way to flash it
[LG V20 Guides, News, & Discussion] draymond1987:
Are you certain that nothing else comes before the laf and laf.bak?

I mean, IF it writes successfully, you would be able to flash our /system. I believe Brian said if it does go bad, we lose DL mode and you would be SOL, yet not, since the phone wouldn't reboot. Right?
[LG V20 Guides, News, & Discussion] runningnak3d:
If you are able to get into download mode after the flash, then you have the V20 laf.

If you really want to know, it will require installing Python.

-- Brian
[LG V20 Guides, News, & Discussion] Josh McGrath:
I'm sure of it, but I'll download a screen recorder just in case . That's a good idea, thanks.

---------- Post added at 01:14 AM ---------- Previous post was at 01:11 AM ----------

I have python 3.6 installed already ? amazingly, windows has it own screen recorder built in.
[LG V20 Guides, News, & Discussion] draymond1987:
Well my question to you is, IF laf flashes, would we know AFTER we pull the plug and reboot? Because then the results should take hold upon the reboot. Sorry for the questions, especially if they sound dumb.
[LG V20 Guides, News, & Discussion] runningnak3d:
Yes, you have to reboot to load the new laf.

If this works, it will be a miracle. :P

-- Brian
[LG V20 Guides, News, & Discussion] draymond1987:
This is like a freaking mystery show! Where you are f5'ing constantly LOL!
[LG V20 Guides, News, & Discussion] Josh McGrath:
The flash also very briefly flashes PERSIST, but I didnt even reflash that on the 932 KDZ so it must not be important

Flashed looked successful, it showed the bar slowly writing in download mode and have the phone booted up just fine now . So now to verify if the LAF flash worked...??

Alright so, the phone boots up fine, but using the USB cord VOL up combo boots into Bootloader now instead of Download mode

EDIT 2: Even LGup goes into bootloader instead of download mode. runningnak3d, man, you called it to a "T" what was going to happen! :)
[LG V20 Guides, News, & Discussion] draymond1987:
Can you get back into download mode? I don't know if that is a way to confirm or not?
[LG V20 Guides, News, & Discussion] runningnak3d:
Try to boot into download mode.
[LG V20 Guides, News, & Discussion] Josh McGrath:
I replied in my thread above, but download mode is definitely gone, not even LGup boots into download mode. You called it correctly Sir!
[LG V20 Guides, News, & Discussion] draymond1987:
So now we are back to square one? [MENTION=3167089]runningnak3d[/MENTION] [MENTION=5070414]Josh McGrath[/MENTION] ?

What about volume down ?
[LG V20 Guides, News, & Discussion] Josh McGrath:
Nothing I do can boot into download mode. If its toast Ill just go get my replacement- maybe, it doesnt really bother me not having DL mode right now . Only thing that sucks is my screen protector
[LG V20 Guides, News, & Discussion] runningnak3d:
Yea, the V30 isn't looking good. I will take a look again once the V20 is done.

This was a nice distraction, and it did let me solve a few things even though they are no use to the V30.

Thanks guys.

-- Brian
[LG V20 Guides, News, & Discussion] draymond1987:
If you think of anything else, I am still fair game, bro! I still have everything intact, so if you need something flashed, don't hesitate to say so.

Good luck with the other devices!
[LG V20 Guides, News, & Discussion] omariscal1019:
So i can go ahead and buy a g6 for cheap lol?? This dude has it for 150 bucks by my work.lol. its tmobile version
[LG V20 Guides, News, & Discussion] Josh McGrath:
I wonder what is different between the g6 LAF and the V30 LAF
[LG V20 Guides, News, & Discussion] draymond1987:
I guess it would make no sense to try a G6 laf, huh?

I overlooked that you had two types of devices. I only seen V20. If you think the method of trying it, is going to result the same as Josh's device, I will just keep lurking on this thread until further notice.

[MENTION=5070414]Josh McGrath[/MENTION] you beat me to that question, aha.
[LG V20 Guides, News, & Discussion] Josh McGrath:
[MENTION=3167089]runningnak3d[/MENTION]

Glad to be a part of the help on other models at least. Its a great learning experience.

So, I wonder what would happen with a factory reset...hmmmm Ill try it before I trade it for my new one
[LG V20 Guides, News, & Discussion] draymond1987:
[MENTION=3167089]runningnak3d[/MENTION] there's two KDZ's to choose from.

http://downloads.codefi.re/autoprime/LG/LG_G6/H872

An older one would be better, I'd assume.

Edit: interesting....I can download just the LAF.img, but will fastboot flash it.

Nope, can't fastboot. I'm an idiot.
[LG V20 Guides, News, & Discussion] ph4nt0m117:
Is the LS997 unlocked?
[LG V20 Guides, News, & Discussion] Zacharee1:
No.
[LG V20 Guides, News, & Discussion] TheDannemand:
As H932 owner, reading up on this thread has been quite the thriller tonight. Frack Netflix!

That was a useful experiment you performed there. Certainly seems like the V20 LAF won't work on V30. We owe you gratitude for donating your device to science!

Sure, it's worth trying a factory restore. But I'd say don't miss your window to get that replacement if today or tomorrow is the last chance. Not having Download Mode kind of eliminates a lot of potential fun down the line.

I'm glad you sat on your hands while Josh did his test. No reason to brick two phones testing the same thing.

I doubt you'll be able to flash or boot LAF.img from fastboot, as they neutered both fastboot flash and fastboot boot. That said, I don't think anybody has tried it with a LAF.img, I guess nothing should be ruled out without testing. Try fastboot boot first since that is harmless. If fastboot flash should succeed (miraculously) you may just end up with the same as Josh's phone.

But I'll be very interested if any owners of US998 (which has full fastboot) are able to fastboot boot LAF.img as asked by [MENTION=3167089]runningnak3d[/MENTION]. Again, that's a harmless test.

Thanks all. This is exciting, even if not that encouraging for V30 owners.

Edit:

You are NOT an idiot! Did you mean you cannot get to fastboot, or you cannot fastboot boot, or you cannot fastboot flash? (The latter two would be expected.)
[LG V20 Guides, News, & Discussion] draymond1987:
Right now, I am downloading a KDZ from the T-mobile variant of the G6. Ending in 0322, as it seems to be the older firmware.

Fastboot did not work, which I figured. As soon as this download finishes, I will see if I can select the laf without having an type of issues.

I am very grateful for Josh's donation of a device. He's got a replacement, if needed. I hope that a factory reset will recover the LAF for him!

I guess I can give an ETA of flashing: about 20 minutes, maybe. The download keeps bouncing around.

---------- Post added at 10:08 PM ---------- Previous post was at 09:42 PM ----------

R.I.P

Flashed laf and laf.bak.... Stuck in a bootloop to the bootloader.

No download mode.

Welp, that was fun, regardless :)

Now, to figure out how to get a replacement when there's a big ol' "bootloader unlocked" message.

Edit: download mode flashes for a second but the bootloader wins.
[LG V20 Guides, News, & Discussion] Josh McGrath:
So the g6 laf did the same thing huh? I went ahead and got my replacement. I did a factory reset and somehow it qworked and booted up fine! So definitely do that on yours. However i didnt get the chance to see if download worked after that cause I had to get my new refurb (im sure theres something wrong with this one too)

Let us know if you get back into download mode after a factory reset.

And dont worry about the warranty, they dont even look that hard. They only care about water or physical damage.

I used to work for tmobile ?
[LG V20 Guides, News, & Discussion] draymond1987:
I'm about to get some sleep but my device is a paperweight. It literally will not boot into the OS.

Tell me how I can talk my way into getting a replacement LOL.

I don't know if I will get another one, if they can help me out. ONLY because I wanna root and flash stuff. I'm not knocking this device. I honestly wish it were like a Pixel. But I may stick to this phone.

Anyways, I need ideas of getting a replacement. I'm afraid they're gonna deny me, for obvious reasons.

Well, good night, folks!
[LG V20 Guides, News, & Discussion] ClockworkImpulse:
Phone was acting funny so you factory rested and it wont boot?
[LG V20 Guides, News, & Discussion] draymond1987:
Well, since there's a big warning, I was thinking: I left my phone plugged into computer, and all of a sudden EVERYTHING got compromised.
[LG V20 Guides, News, & Discussion] Addiso:
Maybe you couldn't boot up becasue LAF.bak was flashed as well? I think the bak is relied on when original LAF fails
[LG V20 Guides, News, & Discussion] Josh McGrath:
I had flashed lag.bak as well though. Maybe the g6 laf is different?
[LG V20 Guides, News, & Discussion] Addiso:
I'm guessing. Wonder what the difference are thinking that the g6 might have been more similar since it's newer but Thanks to you and dray for helping out on these tests.
[LG V20 Guides, News, & Discussion] Josh McGrath:
If youtr with tmobile, just call customer service tonight so they'll send a replacement out overnight.

Just say you had a system update and it went black, thats why i did. Trust me unless you get an asshole , they wont give a damn cause they dont make money off warranty exchanges.

And if you hook it up to the comp, does it say is Qualcomm 9008 in device manager?

Hey if lg disnt screw us and not let us use our phones as we like thrn maybe they wont have so many returns. Screw lg

I HATE lg keyboard ?

---------- Post added at 04:51 AM ---------- Previous post was at 04:47 AM ----------

Hey im glad I could help and learn in the process. The only downfall is that I have to get a screeb protector so im not at much loss here
[LG V20 Guides, News, & Discussion] Josh McGrath:
[MENTION=5830858]draymond1987[/MENTION]

I think I may have figured out what was different with our flashes.

After flashing LAF and laf.bak I *IMMEDIATELY* flashed the h932 kdz system before exiting download mode just in case download mode got nuked. Did you do it in that order?
[LG V20 Guides, News, & Discussion] draymond1987:
I didn't have an 9009 mode at all.

When I flashed the files, I literally pulled the cord right after persist, and only seen system JUST starting. I figured that a second, or millisecond would not effect anything at all. Maybe a mistake on my end.

At any rate, I'm gonna take the phone back to TMobile after work. I'll just say that I'm not sure what happened, and say something about an update. If that doesn't work, I will call customer service.

Thanks for the suggestions and support!
[LG V20 Guides, News, & Discussion] Eliminater74:
Not sure if this could be much help, but after doing a little research on LGUP, (Sorry I was old school long ago with the flashtool) But LGUP is pretty new to me...

anyhow after it was patched to make it dev mode, that allowed you a few more extra options that were not ready before.

I decided to disassemble the DLL to see what else might be lurking in there, I seen this:

some of the others as well, it might make it a bit easier to obtain root somehow.................
[LG V20 Guides, News, & Discussion] BROKEN1981:
It's not going to give you root. Just stay clam and slow down.

I got a notification this morning that an update is available on my H918. I don't think it's Oreo as it says it's only 115 MB. Maybe I'm paranoid but I get the feeling LG really is watching the progress in this thread.
[LG V20 Guides, News, & Discussion] BROKEN1981:
Just a security update. Since we are all ABR1, we can roll back to any ABR1 version of choice.
[LG V20 Guides, News, & Discussion] Sizzlechest:
I'm rooted, but still ABR0. I've been holding back upgrading in case I lose it. Should I wait? Is there a possibility going forward I can flash a newer firmware and remain at ABR0?

It's just 10t.
[LG V20 Guides, News, & Discussion] SJMarty:

[LG V20 Guides, News, & Discussion] draymond1987:
[MENTION=5070414]Josh McGrath[/MENTION] what are the chances of me not getting hit with an out of warranty fee?

I went to T-mobile and explained that I updated the phone and it was on my phone, for dramatics, then it refused to boot.

I typed a lot more, but my PC shut down, so nothing is working in my favor. EDIT: the BL warning was not good for me, as I had to keep explaining that I didn't know how it happened.

Anyways, a replacement is being shipped to T-mobile and it should be there, hopefully when I get done work, since I am literally a few feet away.

I do not know if I will keep the replacement, as I did have a gut feeling to go with another phone. Only because I had some issues when I first got this phone, a few months back. I just want a phone that is more developer friendly, that T-mobile has to offer. Suggestions? Look, I came from an Iphone, and I couldn't deal with the locked down OS. I switch back and forth, so I am not bias, and I've been on Android way longer.

I really am grateful for this little community, and the efforts of everybody on this thread.
[LG V20 Guides, News, & Discussion] jcpowell:
I've got a second device that's got water damage, causing the keyboard to spaz constantly, so I'm willing to flash anything and everything on that POS.

It's an LS997
[LG V20 Guides, News, & Discussion] Josh McGrath:
You'll have no problem getting a replacement. They don't even know what a bootloader is much less how that happebed. You could always just let the phone die too and say it won't power on.

As far as root with another phone, the Moto z2 force is easily rooted and is cheap right now. I really think that's the only other root able phone there. I don't know about the s9 though.

The v30 is pretty good even without root ?
[LG V20 Guides, News, & Discussion] draymond1987:
I am just worried when they receive the device and see the "bootloader unlocked" thingy. I mean, I don't know if they'll plug it in or not, if I let it die? The store manager seen the state it was in, and I have no idea what he typed it, other than what I told him LOL.

The rep knows me, so she was not that surprised, because I talk about stuff with her. She was all "so what do we do this time" *smirk*

Anywho, I do believe you that this phone is amazing without root, but I would prefer a phone I can play with. Sadly, I do not have money for a Pixel, as that would be like paying 3 devices off. I'm on a family plan with my mom. I doubt I can just be like "oh, I don't want any phone now, so take it back."

Also, I figured a way to get into a mode to factory reset. Hold volume down and hold the power button. When you see the logo, let go of power for a second and hold again. BUT it doesn't do **** for me, so I messed up more than LAF. It just goes back to the BL.

Sorry for the OT posting! Feel free to delete, if desired.

[MENTION=5830858]draymond1987[/MENTION]

Once they take the phone in, it's TMobile/Assurant(or assurion) problem. Trust me, with LG and their camera lenses that crack so easily on the g5 and v 10/20, I exchanged several that I should have been charged for. But screw that, I'm not paying for lgs cheap ass misake (I went through about 8 lenses) so you're good
