Hi, is there any tutorial on how to enter the codes in the LG LAF terminal within FWUL?
[LG V30 Guides, News, & Discussion] TheDannemand:
If FWUL recognizes your LAN/WiFi adapter, you should have internet there. So you can simply open this thread in the browser (I forget what it's called) and copy paste individual lines from the guide into the LAF terminal.

To some people, command lines are new and scary, which is OK, no shame. But probably best to find someone to help with this root in that case. As root procedures go, it is among the more complicated ones. But it is a miracle that it can be done at all on this heavily fortified phone.

Agreed about using the FWUL browser and copy/pasting. Just make sure as to what's being copied so you don't get extra characters. You'll be good :good:

I followed the steps to flashing H933 laf only, and that seemed to nearly brick my phone. It turns on to the V30 splash screen and hangs there and download mode does not work. I can get into recovery mode if I have it plugged into usb at least. Is there anything I can do to fix it from fastboot?
[LG V30 Guides, News, & Discussion] TheDannemand:
I couldn't tell you what happened, but it sounds like it may have flashed more than just the laf partition.

I assume your bootloader is unlocked and that you rolled back to Nougat 10d first, right? Sorry, had to ask...

Which LGUP version did you use? If you were ever on Pie, you need to use the latest Dual Mode LGUP from one of ChazzMatt's threads to roll back to to Nougat 10d. AFTER that, you need to use the version of LGUP from post #1 to perform the rest of the procedure, starting with the flashing of H933 laf. Others reported problems until they changed to that LGUP version. You must fully uninstall and clean out LGUP before installing another version.

Fastboot is useless on this model, except to unlock bootloader (true on all models except open market US998 and H930).

At this point your best bet is to take an OTA update in order to restore Download Mode. If you can get the OS to boot, it should offer one to you (since you're presumably on Nougat). I would try a Master Reset to see if that can get the OS to boot (Button Dance, make sure to unplug and power off phone first).

Otherwise you may be able to load the OTA update from stock recovery (which you say is working) although I am not sure exactly how to do that. OTA files have been shared earlier in this thread (some discussion about a year ago, including links).

Good luck to you. Please keep us posted on your progress :)

Edit: I forgot, the LGUP download link in post #1 is dead. You can download from my post here instead.
[LG V30 Guides, News, & Discussion] fsteng:
Thanks for the reply. I am pretty sure I just checked laf. The bootloader was unlocked and it was on Nougat 10d before that. I used the Dual Mode LGUP to get 10d on it. I guess I needed to go back to the other version of LGUP before flashing laf. Perhaps that is where it went wrong.

Now the problem is I cannot get the OS to boot at all. It stops on the LG V30 splash screen and does not progress from there. I left it open overnight, but it really is stuck there. I just tried the Factory Hard Reset. The menu comes up like normal and it goes to the screen with the loop that says "erasing", but it still returns to the LG V30 splash screen and does not advance from there. Unless there is a way to apply that update with fastboot, I think the phone is bricked.
[LG V30 Guides, News, & Discussion] TheDannemand:
I'm sorry to hear that. I don't know that using the newer LGUP would brick the phone like this. OTOH I also cannot think what else would cause it. Even a bad KDZ file or USB connection should just fail to flash by the checks built into LGUP.

Again, fastboot is useless on this model, except to unlock/lock the bootloader (do NOT lock it without being completely stock, or the phone will brick).

My only idea is if somehow the OTA can be flashed in stock recovery. If you can find the OTA file to upgrade from 10d to whatever came next, then put it on an SD card, and try Master Reset to get into stock recovery. That's all I can think of.

Other V30 models have an extra fallback in 9008 mode (there's a thread for that). But we don't have the necessary firehose for H932.

The touchscreen on my H932 died, and I bought a US998 V30+ in great condition on eBay for $115. I believe that seller is still there (YYwireless). Just a thought.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, he's still there but starting about two weeks ago he's raised the "mint" US998 V30+ (128GB) price to $160.

Hey, you deleted your T-Mobile H932 LOS-16 guide?
[LG V30 Guides, News, & Discussion] mattgyver:
Yeah.... I swear on all that is holy, I went to Oreo, then to los16, and had flash. My fingerprint sensor went screwy, so I rebooted. And -gone- lost flash and camera. I deleted the thread so that no one else would needlessly refurb wipe their device until I can figure out what happened. I repeated the steps twice and couldn't replicate it again. Maybe it's my overtired mind playing tricks on me. I don't know.. I know I can set SEpolicy to permissive, but that's not a good solution, as it's not perfect.

What's even stranger is I restored a stock pie backup, not restoring fingerprint/lockscreen data, and the fingerprints were still listed, but I couldn't delete them and I couldn't add more.

Not like there's much to be done. This one pie update from TMo was the last hurrah and it really wasn't worth it (need that, anyone still not on it - don't take the update....)
[LG V30 Guides, News, & Discussion] Tomoose:
Thank you

First I want to thank you for all the work you put into this guide.

Now, I think I ruined my phone, but I don't see my symptoms in this thread.

Here's what I did.

I followed the guide all the way through, flashed the firmware, took the 10h laf, and flashed the remaining partions to 10d. This is when things started getting screwy. The phone wouldn't boot anymore it started flashing the screen off and on with the android logo. I couldn't see it too well it went so quick. In my haste of starting from scratch, I accidentally clicked the erasechip option. Now I didn't think to much at the time, and continued the guide. I've gotten so far, as to get TWRP in recovery and TWRP in my laf. No mater what ROM I flash within TWRP or ADB, I only get the fastboot screen. I'm pretty new to this, and I hope this phone isn't completely bricked. I can't seem to get download mode back. I tried to reinstall the stock laf, and the laf from this thread, but the screen only shows unknown and my computer doesn't recognize the device any longer.

Any ideas?
[LG V30 Guides, News, & Discussion] mattgyver:
Chip Erase wipes efs/IMEI :eek:

Have you tried running back through from scratch and following the guide again? At least to get your phone back to having the download mode and hopefully to get you a working device.
[LG V30 Guides, News, & Discussion] Tomoose:
What are efs/IMEI ? I assume my carrier won't let me use this phone anymore?

Where should I start? I can't get download mode to recognize my computer/ LGUP to recognize my phone. TWRP is working "fine" i guess. I tried to flash the orignal laf back using ADB, but that didn't seem to work.

Thank you for the quick reply!
[LG V30 Guides, News, & Discussion] mattgyver:
D'oh.... Stupid me. Yes... no download mode, no chance of following this guide. Do you have the h932 laf zip that you could flash it in TWRP?
[LG V30 Guides, News, & Discussion] Tomoose:
Yes, I flashed it, and booted to download mode. I get to the screen that says firmware update now waiting for any connection, it seems normal, but at the bottom it says:

" Unkown: B96

Unknown / E / L / R0"

My computer doesn't recognize it's plugged in
[LG V30 Guides, News, & Discussion] ChazzMatt:
Having two copies of TWRP -- one in LAF partition and one in normal recovery partition -- disables Download mode. Download mode lives in LAF partition. Perhaps flashing latest Oreo TWRP-flashable zip will give him Download mode back. That dev [MENTION=9374982]weakNPCdotCom[/MENTION] warns it will overwrite the "spare" TWRP in LAF and will restore Download mode -- which in this case we want. ;)

He also has a separate

stock T-mobile H932 LAF zip file which can be flashed in TWRP

. < Download that and flash in TWRP.

Or flash the full TWRP flashable Oreo firmware from here:

You flash it in TWRP. Do you have TWRP custom recovery?

[LG V30 Guides, News, & Discussion] Tomoose:
Yes I used TWRP recovery, i used both the zip, and the extracted img. within TWRP i used install and adb shell commands to flash laf partition.

I'm looking at my ebay history now, and I think i done goofed, the phone was sold as H930, but the img installed was H932 from tmobile when I recieved it. Maybe that is why this has been failing?
[LG V30 Guides, News, & Discussion] TheDannemand:
What you have right now is one leg (TWRP) of a three-legged stool (Download Mode, OS, TWRP). So careful not to lose that leg.

I agree, try flashing [MENTION=9374982]weakNPCdotCom[/MENTION]'s H932 20s FullStock.zip from the thread linked by ChazzMatt. Hopefully that can restore both your Download mode and a working OS.

Which version of LGUP are you using? We know that the latest Dev Patched version is needed to roll back from Pie (download from one of ChazzMatt's threads). But some users found in the past that once you're on 10d, you have to switch to the LGUP version from Brian's guide in the opening post for the remaining steps, starting with flashing the H933 laf. Unfortunately that LGUP link is now dead. I shared a copy here and I know others have shared copies too.

I ask because maybe using Brian's original LGUP will help in detecting the phone when it says Unknown in Download Mode. After all, that's an old H932_laf.zip you flashed, so maybe using it with an old LGUP makes sense.

Once you (hopefully) get your phone working again, the thread linked below has steps to fix the lost IMEI. The Hidden Menu trick sounds easiest, although I've never tried it myself, and I don't know if it also works on H932.

Please help me restore LG V30 lost SN and IMEI. I check ChipErase in LGUP

Edit: Oh, I see now that the phone may actually be an H930. If it's anything other than a H932, and you flashed a H932 KDZ onto it, then it's now a brick. Sorry to say.
[LG V30 Guides, News, & Discussion] Tomoose:
I'm trying to be very careful not to mess with the recovery. I belive the problem lies with the phone not using the USB in download mode. My computer doesn't recognize anything is plugged in. I have used both versions of LGUP to get it to it's current state.
[LG V30 Guides, News, & Discussion] mattgyver:
Before you go ANY further, you have to be absolutely 200% sure what phone you have.. is it an H930 or an H932? What OS was on it when you bought it? Stock Oreo, stock Pie? AOSP variant? The H932 has a unique RSA signature. You can't just up and cross-variant flash or you end up with an expensive paperweight.
[LG V30 Guides, News, & Discussion] Tomoose:
Just seeing your edit now, Thanks again for all your help. I knew this would be risky getting into it.

Are you certain there is no way I can restore this, even with TWRP? Maybe another laf image, or stock image?
[LG V30 Guides, News, & Discussion] TheDannemand:
Understood. I'm glad to hear you already did that. Sounds like you did everything right here -- except it may not be an H932.

Unfortunately if that is the case (and as I understand) a QFuse will blow the 2nd time you try to boot after flashing an incorrectly signed partition. Because you unlocked the bootloader, signature checking is relaxed for recovery, system, boot and laf. But since you flashed an entire 10d KDZ several other partitions were flashed as well. I suspect that's why it shows Unknown in Download Mode and nothing is working. If that QFuse is blown, there is no way back (well, replacing the motherboard).

Edit: There is an XDA member who has helped with semi-bricked V30s in the past, remotely using an Octoplus box, and for a fee. Maybe ChazzMatt remembers his name. H932 was always excluded because nobody has a firehose for it. But looking at the Octoplus website recently, they list H932 as supported, so maybe they got hold of an H932 firehose. Still, I don't see how that can fix it if the QFuse is blown, since it irreversible changes the chip itself.
[LG V30 Guides, News, & Discussion] Tomoose:
I was sure it was an H932, but i'm no longer sure. Ebay says H930. There's no box or sticker on the back to go off of.
[LG V30 Guides, News, & Discussion] TheDannemand:

[LG V30 Guides, News, & Discussion] TheDannemand:
Congrats, that's good news. Now back to the regularly scheduled program :D

Try to flash that 20s FullStock.zip in TWRP, as suggested by ChazzMatt.

Couple of other thoughts regarding Download Mode and LGUP: Check in Device Manager that your USB port is working right (I have an old Samsung laptop where USB3 ports like to stop working; disable/enable sometimes helps; restart always does). Restart Windows (NOT Shutdown, Restart, they're different). Try a different USB port. Try a different USB cable. Completely uninstall LGUP and re-install it. Try a different computer.

People always scoff at those trivial suggestions ("I'm not THAT stupid") and then get very surprised when they (often) solve the problem. Of course I don't know if it will in your case.

I have to take off. Lots of work today. Good luck to you :good:

[LG V30 Guides, News, & Discussion] TheDannemand:

Can I do the root process somehow without an SD card?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Uh, only if you don't have a T-Mobile H932. This "LAF" method is the only root procedure available for T-Mobile H932, and you have to follow instructions exactly. Also it's ONLY for the T-mobile H932.

All other V30 variants use WTF method -- or even official LG bootloader unlock -- and those don't require microSD card.

You are lucky the Dev figured this out for T-Mobile H932 or you wouldn't have anything.
[LG V30 Guides, News, & Discussion] TheDannemand:
As Chazz said: This phone (H932, not the other V30 models) is locked down so hard, it took an enormous amount of work, by a genius (no less) to discover and develop this root procedure.

SD cards used to come free with early Android phones (such as my first LG Optimus V). So many people have old ones lying around, too small and/or slow to be useful, but good enough for this. It only has to be 1GB (even less, if that exists).

Or you can buy one on AliExpress for $2-3 with free shipping (you have to scroll past the so-called free ones). Of course it'll take 1-2 months to get to USA (if that's where you live).

Edit: Are we taking about the same phone you mention in the thread linked below (which sounds to be already bootloader unlocked and rooted)?

https://xdaforums.com/lg-v30/help/oem-unlock-greyed-t4113599/post82849139
[LG V30 Guides, News, & Discussion] ChazzMatt:
Hmmm....

Just be careful. This method in this thread is only for T-mobile H932. All other V30 would use WTF method -- including H932PR. H932PR (Puerto Rico) and T-Mobile H932 have nothing in common except for LG's laziness in not calling it H934 or something... You list Santo Domingo in the Caribbean as your location, so just double checking.

ROOT Your LG V30! and Custom ROMs FAQ
[LG V30 Guides, News, & Discussion] l3dson:
This is the version I have.

I bought the used phone, when I entered the recovery the first time I had twrp, but I lost it when I updated to Android 9 unfortunately, I was not very specialized in that.

I tried to contact the seller of the phone to get information, but I couldn't.

I managed to download to Android 7 very easily and I got the SD.

The bootloader was always unlocked and I had no brick problems when I touched it.

There are steps that I don't understand, for example, why do I need this KDZ? :

"You must have H933 10h laf installed. You will need the KDZ"

Before continuing, I want to know if the correct version is what I have, if you can tell with the images I uploaded.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Because this root method uses a LAF Partition from another North American variant, the Canada H933. But ONLY that one Partition and ONLY if the bootloader is first unlocked. It's the one exception to the ironclad rule not to cross flash any other variant firmware over T-Mobile H932.
[LG V30 Guides, News, & Discussion] l3dson:
How do I realize which version of t-mobile is the one I have?

I mean as if it is not the one from Puerto Rico for example.
[LG V30 Guides, News, & Discussion] ChazzMatt:
In About Phone the Puerto Rico variant says "H932PR".

All the other H932 are T-Mobile H932.
[LG V30 Guides, News, & Discussion] TheDannemand:
That's a great catch there, I didn't think of that!

If this is an H932PR, flashing an H932 KDZ will brick it (since the KDZ contains partitions that are NOT exempt from RSA checking even with unlocked BL).

If you're saying you rolled back to H93210d using LGUP -- and the phone is still working -- then we know it's H932, NOT H932PR. Settings -> General -> About phone -> Hardware info should confirm it, but it will just display whatever ROM is flashed.
