Are you sure you are in fastboot mode?

1) Enable OEM Unlock in Developer Options.

2) Turn off phone.

3) Hold Vol- while plugging USB cable into phone (other end already plugged into PC).

4) Type fastboot devices to verify connection.

5) Type fastboot oem unlock. Phone will wipe itself completely.

Do NOT proceed to flash H933 laf until bootloader is unlocked!

followed your exact steps but got something a bit different
[LG V30 Guides, News, & Discussion] jonahnm:
(repost quoted the wrong thing) followed your exact steps but got something a bit different
[LG V30 Guides, News, & Discussion] TheDannemand:
Two things come to mind:

A) This isn't an H932 with easy bootloader unlock. Under About phone -> Hardware info does it say H932? ONLY use this guide on H932. Other North American models use WTF to unlock BL.

B) Enable OEM Unlock wasn't done in Developer Options. Is it enabled when you check it now?

That's all I can think of.

Happy New Year!
[LG V30 Guides, News, & Discussion] jonahnm:
Yeah it says LG-H932 as model number and i have OEM unlock enabled in dev settings also this phone is an lg V30 ThinQ but i dunno if it makes a difference
[LG V30 Guides, News, & Discussion] TheDannemand:
Understood. They're all V30 ThinQ. It's just a brand update they made.

Which OS version?

Try and roll back to Nougat 10d first. Come to think of it, I recall some others mentioning problems unlocking on later versions. But strangely not everybody.

If you are (or have ever been) on Pie you must use the latest LGUP from any of ChazzMatt's Pie ROM threads to roll back. Use Partition DL. Uninstall any previous LGUP version first and install it exactly as described in his threads, including Windows restart.

Once you are on Nougat and (hopefully) have BL unlocked, you must uninstall that LGUP and use the one from post #1 of this thread for the rest of the root procedure.

Good luck :)

Edit: Fixed typo mixing Pie/Nougat
[LG V30 Guides, News, & Discussion] jonahnm:
THanks for the info! will try downgrading to nougat now
[LG V30 Guides, News, & Discussion] jonahnm:
Just to clarify I select Partition DL and keep all the boxes checked?
[LG V30 Guides, News, & Discussion] TheDannemand:
Correct. H93210d.

Normally Refurbish should do, but when coming from Pie I recommend Partition DL.
[LG V30 Guides, News, & Discussion] jonahnm:
Yeah I am coming from Pie so I will use Partition DL and keep all the boxes checked while using LGUP Dual Mode Dev Patched from one of ChazzMatt's Pie threads.
[LG V30 Guides, News, & Discussion] jonahnm:
NICE i downgraded and fastboot OEM unlock worked! Thanks
[LG V30 Guides, News, & Discussion] jonahnm:
(Quoted the wrong thing again lol) NICE i downgraded and fastboot OEM unlock worked! Thanks

So for the rest of the procedure I use the other LGUP right?
[LG V30 Guides, News, & Discussion] TheDannemand:
Good job!

Yes, use the other LGUP for the rest of the root procedure. But the newer one is recommended for anything to do with Pie.

Just follow the Part 1 steps in post #2.

Post #1 mentions unplugging the USB cable to interrupt flashing H933 after laf, which the OP later confirmed you don't need to do. I could have sworn he updated this in post #1 as well. I think an older version of that post may have been restored accidentally at some point.

Good luck (y)

I have succesfully gotten TWRP on the recovery partiton but i need to know if it is safe to update twrp from twrp on this device (becasue the pie stock flashable via Twrp lists a newer version)
[LG V30 Guides, News, & Discussion] TheDannemand:
Well done rooting your H932!

You should be OK to update to a later TWRP using TWRP. Certainly if it's a TWRP version listed in one of the stock H932 threads.

I no longer have my H932, and never went to Pie on it. Kept it on latest Oreo.
[LG V30 Guides, News, & Discussion] MikePysh:
Hi there. I cannot for the life of me downgrade my lg from pie down to nougat like we're supposed in this tutorial. I get an error every time because I can't get the right DLL for LGUP. I'm really frustrated. I understand how to follow instructions but not for downgrading obviously. I've done it before on other phones so I don't see what the problem is? Would someone be able help me with this part before I throw my phone in the fire? I just wanna root this phone and I'm up to challenge, but I'm up against this brick wall right now. For something that seems so easy, it's just not working for me today.

Urk, i think i may have posted too soon because i think i figured it out by lgup dual mode and am currently booting nougat as i type this, yep, so easy a caveman can do it. Now onto the rest of this festivus!
[LG V30 Guides, News, & Discussion] MikePysh:
Well, now im really stumped. I was sailing in part 2 and am in fwul. After first three lines of code i a whole bunch of lines that looks something is not working and I do not know what to do.

I read in this thread that someone else had the same problem, but i dont understand how they were gonna fix it. Im lost and I'm scared that phone is gonna be f**t now. I hope not.

Please, if someone could enlighten me on this issue asap i will forever indebted to you. Please please help me!

So I unplugged the device from my laptop and the phone is working. I just flashed pie on it again so I could have working phone. The bootloader is still unlocked, but I have know idea what to do now. I'm reading up around the internet to see my options. If I had of known that this phone would be such a pain I arse to modify, I wouldnot have bought it. I don't know what Im gonna do with it now. I would still like to obtain root on it of if I can figure it out, but I am seriously contemplating buying another phone again. One that is not not such a pain to modify. This is second time I bought an LG that had to be so whacky to play with, the latter being the G4 from Verizon. I gotta stop doin this to myself lol...
[LG V30 Guides, News, & Discussion] ChazzMatt:
Glad you got this part figured out. It's really the easiest, compared to the rest necessary for the T-mobile H932.

Yeah, the T-mobile H932 is the hardest nut to crack of the V30 models. All the others can use the WTF method.

As you know the problem is T-mobile/LG put in totally different RSA encryption for this model ONLY -- of all the 2 dozen V30/V30+/V30S variants.

With what we know now, the only reason for someone to buy T-mobile H932 would be if they were a T-mobile customer and NEEDED LTE band 71. Even then, many T-mobile customers buy US998 or LS998 and convert to US998. (US998 firmware allows T-mobile VoLTE and Vo-WiFi.)

Even the Dev of this thread (who is a T-mobile customer) sold his T-mobile H932 to get the current OnePlus phone at the time -- quickly ditched it as crap, and came back to the V30. But the 2nd time, he bought a US998.

However, you CAN do it. This thread exists because it does work. Just takes patience!
[LG V30 Guides, News, & Discussion] MikePysh:
Yeah didn't know that and obviously didn't do any homework. I'm from Canada and I bought this one used off of someone because I was walking around with a rotten Apple. I really have no idea what to do next but it's going to take a whole lot of learning it seems. I'm pretty sure I will just ditch this one and move on to something a lot more user friendly because this one hurts my brain. It's too bad because this really is a nice phone but can't be unleashed to its full potential so in a way it's broken to me. Thanks T-Mobile 🤬
[LG V30 Guides, News, & Discussion] MikePysh:
Since I didn't actually achieve root yet, I do have a strange sort of problem. After my phone boots up and after the bootloader unlocked screen warning, it switches to a screen with a padlock with a spinning circle around it. And then the phone starts up and goes a verifying app rigmarole and then the phone seems normal after that. Does anyone know what that's about? It seems to be working fine so far but it has that little quirk at startup.
[LG V30 Guides, News, & Discussion] zfk110:
I got H932 with TWRP and Oreo installed, but this phone is locked to T-Mobile for me to unlock I have to put the phone in download mode, since there is TWRP installed how can I get back to download mode without messing things up? Because when I try to go into download mode it takes me back to TWRP.

You can unlock H932 using this method without any issues see this video

for that method to work I have to have download mode, since I followed your WTF V30 H932 guide I was able to root my phone, but I found that method later on that why I was asking to get the download mode back. Is there any way to get back the download mode without messing anything up? Since it's replaced with TWRP.
[LG V30 Guides, News, & Discussion] TheDannemand:
Go to the H932 20s thread (linked below) and fetch the StockLAF.zip file. Flashing that in TWRP should restore your Download mode. Of course make sure you have TWRP on recovery too before overwriting the one on laf.

I got stumped for a few hours trying to get laf on the FWUL OS read my sd card. I re-formated the sd card, partitioned it many times, renamed the TWRP file, and redid all the steps two times with no luck. I have a 32gb card that I partitioned down to 512mb and is on fat16. I read the instructions over and over again and read many of the posts before posting mine. I don't know what's missing. Update: I swapped sd cards to no avail, renamed the twrp file to twrp.img (that's the file extension) and reflashed the phone a third time to see the same thing on FWUL.

Hi I got LG v30 is not rooted and OEM locked it's still locked so what happens I downgrade from Android 9 to Android 8 and once I do that phone's boot up fine, but it's stuck with that T-Mobile logo it would not pass that when I go back I can go back to download mode or I can go back to fast boot mode and if I want to I can also reflash at h93210d and it will stuck into the T-Mobile logo for a minute and then it will say Android is starting do not turn off phone and then it will go back to 98% and then he will restart again so I don't know what's going on with it

I can hear the T-Mobile chime and I can see the T-Mobile logo with the white background and then it will go back again I did try do hard reset and that did not help I don't know if the motherboard is done for a day or something else can be done to fix this thank you

boot the phone normally and see if your sd card can be seen inside the phone or not? I had an issue with V30 I bought and that v30 had broken sd card reader inside which failed to read the sd card no matter what I did

lately I having a very hard time to

Boot from your FWUL USB stick. I tried two different PCs and 3 different USB stick, but I can't boot into FWUL anymore, is there any way around to it? Can I use Ubuntu live CD instead?
[LG V30 Guides, News, & Discussion] AllanRSS:
I followed the instructions to a T (as much as possible given inconsistences/out dated info) but I can't get any response from lglaf. I am able to enter the interactive shell, but all commands using !EXEC do not output or show any indication of working. The !CTRL command does behave as described. I get this behaviour from FWUL 2.7 and from my own Arch system. The latest version of FWUL did not have a function lglaf.

I will try reinstalling the h933 laf, but I am hesitent given the risks and that the first time everything went smoothly. I will say I did not flash the h933 lafbak and I did flash the h932 lafbak along with the rest of the partitions, since no mention was made of this in the guide. The laf flash took about 2 seconds, and everything booted up fine after finishing the h932 flash.

hey guys,i have a T-MOBILE Sim-Locked LGV30 thinQ H932 with the latest version (android 9 Non-ROOTED),Any new step by step method To Unlock it for free :( i want to sell it or throw a custom rom on it..it's such a good phone and i don't want to throw it just like that. Thank you !

is it a stock ROM? if so, you should see unlock app. I think you should pay off already as well. just click on that app to unlock it for free.

yes stock rom,and it says "non eligible to unlock" on the unlock app :/

[LG V30 Guides, News, & Discussion] br@inmatr:
Good evening, Sir.

A quick synopsis of my current predicament:

I have a battered, bruised and beaten TMO LG V30 64GB version.

The phone was recently bootloader unlocked and running on Android 9, but decided to downgrade to Nougat 7.1.2 to attempt TWRP and root installation (still bootloader unlocked). So far, so good; no bootloops, perma-bricks and/or download mode removals have been seen (knock on wood😏).

I've performed all the steps successfully in part 1 of the LAFploit, but running into issues burning an image of FWUL on a SanDisk USB stick w/32GB of storage.

This is my hangup on part 2 of this very tricky procedure.

Still searching the net for other flashing programs, but any tips on part 2 would be most helpful. Thanks in advance.
[LG V30 Guides, News, & Discussion] br@inmatr:
Tried that and will not work. This particular model HAS to be rooted in order to be carrier unlocked. This is the level of f*****y LG and TMO have done to this version of the V30.😕
[LG V30 Guides, News, & Discussion] diggr:
After I do the git pull and git checkout, I have no step1.sh. Has anybody else ran into this?

(solved): I used the dd commands that appeared in the next couple of post replies.
[LG V30 Guides, News, & Discussion] br@inmatr:
I have an even better question.

What external flash drive did you use to burn the TWUL image onto and what brand? I've already ruined 2 SanDisk thumb drives and I'm hesitant to break another one.😅
[LG V30 Guides, News, & Discussion] diggr:
Well, I figured out my problem. I didn't read further down into the instructions. What a n00b.

To answer your question, I used a generic Patriot 2GB stick I got probably 12yrs ago. When I do things like this, I like to stay below 4GB.

However, I also converted the ISOs to VMDKs using the Virtual Box converter on the 2.7, 3.1, and 3.2 versions of FWUL and they all worked okay in VMware Workstation. VMs aren't recommended, but they seem to work fine.
[LG V30 Guides, News, & Discussion] br@inmatr:
Well, I was able to boot into what looks like TWUL but don't know what mode I should run when the options menu briefly flash on the screen.

I get a [rootfs ]# prompt on the screen.

I'm trying to get all the assistance I can because this is, by far, the toughest part of this TWRP flash.🤷🏾‍♂️

Also, the device doesn't seem to be recognized by the PC which means something is off.
[LG V30 Guides, News, & Discussion] duytung277:
I completed all step and installed twrp, but when i install rom (RR, Dotos, Havoc,...), i get many bug (wifi, finger,...). Now, i can install rom for H932 or H933 after use H933 LAF ??? sorry for my English :"(
[LG V30 Guides, News, & Discussion] diggr:
No, that doesn't sound correct, you should boot into a GUI; but it might be enough. If adb runs, you've set the phone for USB debugging, and USB is set for file transfer, you should see the phone in an 'adb devices'.
[LG V30 Guides, News, & Discussion] diggr:
Those bugs are normal. You need to find a file called "[RECOVERY] WiFi_Fix_LG-v30_v2.zip" to fix the wifi. It installs from TWRP and it'll fix the wifi issue. I found it in the Telegram channel.

I have not fixed my fingerprint issue. They say if you reflash the oreo modem file, it'll fix the finterprint reader.

[LG V30 Guides, News, & Discussion] Sakuryu:
Hi, in reading through the V30 forums I was on my way to unlocking and rooting my old backup V30+ and apparently got my wires crossed somewhere? I have a T-Mobile V30+ and I used the DualMode LGUP file to flash 20b onto it.

I *think* this is where I f*cked up since reading into more forums it seems like it doesn't like to cross flash with my model?

My fault yeah but I got there through some link hopping since I was on A9. Anyway, I have a black screen now. Can't shut it off, turn it on whatever. QUSB_BULK.

Any idea how I can unbrick this? I can handle whatever code or programs if I need to read into junk.
[LG V30 Guides, News, & Discussion] ChazzMatt:
WHICH 20b did you flash? For what model? It has to be for the T-Mobile H392, not any other models. H932 20b KDZ (stock ROM).

You have an actual T-Mobile H932 V30+ (128GB)? Those were only sold for limited time. Most H932 are the V30 (64GB).

Why 20b? To root the T-Mobile H932 you would be using Nougat 10d first, if you read these directions. There's no mention of 20b in these instructions, whereas for the WFT instructions you have to use early Oreo like 20a or 20b for the bootloader unlock exploit -- but those instructions are not compatible with the T-Mobile H932. The T-Mobile H932 is the hardest to root and can only be done by this specific method in this thread.

If you actually have a T-Mobile H932 V30+ or even the 64GB V30 H932 and you flashed any other model (US998, H933, H930*, H931, VS996) full KDZ over it, you have permanently bricked it. We have plenty of warnings everywhere about NOT cross flashing other stock firmware over T-Mobile H932.

To root the T-Mobile H932, you do have to flash a single partition (LAF) from the H933 (Canada) Nougat 10d, but that's ONLY after you have unlocked the bootloader. That relaxes the security chain enough you can safely flash that one partition from another model (but it's still scary) to then install TWRP and root through a very convoluted method. The OP who came up with this is a genius, but you have to follow the steps exactly.
[LG V30 Guides, News, & Discussion] Sakuryu:
Launch day T-Mobile V30+ with the original Headphones. I got it myself by trading in my old V20+ I believe. I was following a guide to unlock the bootloader which mentioned flashing "US99820b_03_0524.kdz" First since I was on a newer version I think?

I used the "Dual LG UP" Provided in the thread. I believe it was "The Frankenstein Method" I think the website or thread I was using didn't have the bright red warnings this page has.

So it seems I've likely made a very pretty paper-weight. Is there anything I can do to mess with it or practice repair methods on? It was my old phone that was only setting in it's original box prior to this so I'm not too broken up about it.

If there's nothing I can do that honestly kind of sucks, I'd like to tinker with it more since I haven't messed with phone stuff in a long time and wanted some ADB and ODIN practice before even thinking of touching my Note 10+ When it can be rooted.
[LG V30 Guides, News, & Discussion] ChazzMatt:
The H932PR (Puerto Rico) is totally different from the T-Mobile H932. The H932PR is like the other North American variants -- US998, Canada H933, AT&T H931, Verizon VS996. Whereas, T-Mobile H932 has a different encryption system than any of the other V30/V30+/V30S. LG should have named the the Puerto Rico model the "H934" or something, not re-use a number already taken.

IF you indeed flashed T-Mobile H932 firmware over your H932PR phone, it's hard bricked.

We

talk about the H932PR in other threads where you also posted in

as well as the Frankenstein thread. I'm very sorry you bricked your phone, but you should have researched first.
[LG V30 Guides, News, & Discussion] callihn:
Couldn't get etcher to write the latest FWUL image, trying Rufus said it was missing files in it due to different versions conflicting which it offered to fix,. WIll see.

The h932_laf.zip link is dead.

No links to other files? rctd killer...?

I'm assuming that the post below 1 are the long version which is now taken care of with the script? Good it's included in case something else goes wrong. though I think the script should use twrp.img so the latest version can be used instead of the exact file name.

Thanks for the post.
