Succeeded in not ruining my phone, and paid my "SunShine" entrance fee; my slightly-dented H932-UBK and I are now members of the cool kids' club. Two years late, but better late than never, eh?

I'd like to take the opportunity to thank everyone who chipped in, making the instructions as clear and detailed as they are. Aside from having to force Windows to install the V30 fastboot driver, and wiping out TWRP on the first try because...I don't know, actually, it decided to reboot when I let go of the keys in the reset screen...everything went smoothly.

It's been said before, but to confirm: unlock status persists through the process ( plus TWRP on LAF) and flash to debloated 20s. Trying to unlock in the TMO app results in "Unlock Failed: Unlock Approved: Mobile device is permanently unlocked", same as in full stock. I wonder where on the phone this is stored...

May ask is it a way to get the OTA file for Pie update? I lost download mode and I already update to Pie. Is it the only way to get download mode is to flash on OTA? TQ..
[LG V30 Guides, News, & Discussion] brombadeg:
Maybe it is obvious to many, but can someone tell what does this mean:

"Network Lock" is shown when I reboot the phone when I put in a non-T-Mobile SIM to the phone (V30). Does not asks for SIM unlock code?

Facts:

-waited 30 days (not 40) on T network

-H93230d

-Pie

-Bought two V30 from different seller as T-Mobile ones, second hand on Swappa. Both arrived with Nougat, then went to Pie....

-Not black listed

-When I went to T-Mobile, they showed me the IMEI is unlocked(green, so probably paid off), but the Unlock App does not unlock. Also calling them did not help, they refused to unlock it (even if it is not locked?) with some silly reason. I'm confused about this type of lock. This is the one called SIM Card lock? Or was this phone with another Network provider then someone put a H932 fw to it? Maybe I should go to T-Mobile forum, but since I was thinking just to root it and unlock if possible after OTA..
[LG V30 Guides, News, & Discussion] zapzapdew:
I've been looking everywhere for it. Have not seen it yet.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, this means you the phone is "carrier locked"/"SIM card locked" to T-Mobile.

This is why I've advised people not to buy T-Mobile H932 V30/V30+ UNLESS you are a T-Mobile customer. Are you T-Mobile customer? If not, is there some reason you want a T-Mobile V30?

T-Mobile H932 is also the most complicated of the V30 variants to root. (The others are easier, using the WTF Instructions.)

For recent T-Mobile phones, ONLY T-Mobile servers (using the app) can carrier unlock/SIM card unlock the phone and sometimes even upgrading to new OS (like Oreo to Pie) re-locks it.

Sometimes even T-Mobile can't unlock their own phones. We've seen examples here...

There's a few online vendors who can SIM card unlock T-Mobile H932 phones -- but involves downgrading phone to Nougat and spoofing another T-Mobile phone model to fool the T-Mobile servers.

If someone offers a simple "code", that will NOT unlock it.

The silly reason being you didn't buy the phone from T-Mobile. ;) Are you even a T-Mobile customer?

No, that would be impossible. T-Mobile H932 is the only North American V30/V30+ variant which can NOT be cross flashed to another variant, and vice versa. Trying to do so will hard brick it.

You have to temporarily downgrade to Nougat to root the phone. Not sure why you are waiting for some OTA...

But if you can't SIM card unlock the phones, and if you're not T-Mobile customer, then you need to sell them and get V30 more compatible for your needs.

Who is your carrier/provider?

3 hours later.

IT IS DONE.

JESUS H CHRISTMAS....

It was harder 2nd time around because I had to use a 2nd phone as mobile hotspot for the git commands but I did it.

Time to format the SD card back to 64GB and play with some roms. Goodnight and good luck.
[LG V30 Guides, News, & Discussion] brombadeg:
Thanks!

Yes, I'm T-Mobile customer for two years and since we are planing to travel a bit, I need to put another SIM.

When I bought it, I hadn't thought it would be a problem and I needed a full coverage under T.

The silly reason was: "I did not buy it from BestBuy or Costco".. only those they unlock. It is not written among the unlock rules though and I don't get it why they are so reluctant. If this phone is paid off and was T-Moible one (as you said there is no cross flash for H932), then they shouldn't fuss about it imho. I'll probably try again with another representative.

So, you think better to sell it and buy an 'unlocked' one, rather than go over this downgrade, flashing process? I saw it works for many. I would be of course more happy if T unlocked it officially.

I'm still confused however if their system showed "unlocked" when searched for the IMEI, why it is locked?
[LG V30 Guides, News, & Discussion] TheDannemand:
See T-Mobile's Device Unlock requirements here. There is nothing about Costco or Best Buy. But they DO require Proof of Purchase, and that may be the issue when bought from eBay. Also, the phone must be on active T-Mobile for at least 40 days (Postpaid).

If you are certain that you fulfill their requirements, and they still refuse or are unable to unlock it, you should file an FCC complaint. That will escalate it to T-Mobile's Executive Office, who will solve it quickly. But only do this if you are sure you fulfil their requirements.

It's still true what ChazzMatt says that you are better off with another V30 model -- except H932 is the only one with LTE Band 71, which is nice if your area has it.
[LG V30 Guides, News, & Discussion] ChazzMatt:
OK, so you are T-mobile customer -- you just want some freedom. Understood.

I am not sure why the T-mobile system shows "unlocked" but your phone shows "locked" when you put in another SIM card. Possibly it means it's not "locked" to some account, that it's free to be activated on T-mobile. Many people try to sell phones before they have been paid off, so there's often a "hold" placed on the IMEI.

There are two downgrade, flashing processes I referred to -- and both involve Nougat:

* The first one is if the T-mobile unlocking app doesn't actually unlock the phone, there are a couple of online vendors who can get it done. Do NOT believe any who offer to sell you a code. Instead, I believe they have to remotely connect to your PC and do some stuff through it with your phone. They downgrade to Nougat, spoof another T-mobile phone model and then use T-mobile's app to "unlock" that phone. We had a post detailing who to contact for that, but due to XDA rules it was removed since those people charge money for their service. No paid services are allowed to be posted in the discussion forums. You can search eBay and probably find them. Just be wary of people trying to sell you code, even if they offer "money back" guarantee. It will NOT work.

* The 2nd is for TWRP installation and root, from instructions in this thread. Unlike the other North American V30 variants, unlocking bootloader, installing TWRP and rooting will not remove the T-mobile H932 carrier lock/SIM card lock status.

See, since you are a T-mobile customer the answer is harder. The H932 has T-mobile LTE band 71 which is being rolled out. The others do not.

Conversely, the dev who rooted this phone and who created this thread and IS a T-mobile customer himself sold his H932 to get the overhyped OnePlus, almost vomited over it, and a few weeks later quickly came back to V30. But this time he got US998, even though he's still a T-mobile customer. US998 is carrier unlocked and allows T-mobile Wi-Fi Calling. But doesn't have LTE band 71.
[LG V30 Guides, News, & Discussion] brombadeg:
Yeah, I know those requirements, but thanks. They don't speak much about second hand customers in this article though. I was trying to be eco-friendly not to buy the latest new all the time, since this HW is still more than enough for me.

I was also thinking on FCC or flash/root/etc.

And the phone is many times on B71 when I checked, so it is a good thing for me so far at least.
[LG V30 Guides, News, & Discussion] TheDannemand:
So that's one good reason to hang on to H932 (B71). FCC complaint works, I've used it and so has others in similar situations. I seem to recall the 3rd party service Chazz referred to is called TMB Killer, but could be wrong. I don't know if they still require editing build.prop like when we got the first report about them. If so, you'll need to root first.

As Chazz said, don't give money to anybody who claims they can unlock a TMO phone with a code, they're lying.
[LG V30 Guides, News, & Discussion] eqroiueq:
I'm trying to follow these instructions, but can't get to fastboot mode.

- I have USB debugging and OEM unlock checked in developer options

- I plug in the phone. It shows with `adb devices`

- I issue `adb reboot bootloader`

***- The phone reboots to system

- I unplug the phone and turn it off.

- I hold vol down and plug the phone into my computer

***- The phone's screen cycles between black and the LG logo for several minutes (so far, I've only tried for up to 5 minutes) until I get tired of holding vol down, at which point it boots to system.

So how do I actually complete this step?

[LG V30 Guides, News, & Discussion] TheDannemand:
You're reading the steps right, but several people reported problems getting to fastboot on Oreo. For that reason, I chose to downgrade to Nougat first when I rooted my H932, before unlocking the bootloader. And I had zero problems.

So [MENTION=3800508]gavilan2010[/MENTION]'s advice is a good one :)

[LG V30 Guides, News, & Discussion] eqroiueq:
Awesome! I was able to get to fastboot mode without a problem after flashing the h932 10d rom.

My experience:

- I had to flash the h932 10d rom *before* I could get to fastboot mode.

- The link for LG drivers no longer accurately describes what I saw on LG's site, but searching for "LG universal mobile drivers" gave me working drivers.

- The LG site wouldn't let me download the h932 10d or h933 10h ROMs on any device and browser I tried. Thankfully, they're available on Android File Host. I just copied the link and searched for the file name.
[LG V30 Guides, News, & Discussion] eqroiueq:
So I have the device rooted, with TWRP installed in recovery and laf. The phone worked fine while running 10d.

I tried flashing LineageOS 16 from here: https://xdaforums.com/lg-v30/development/rom-lineageos-15-1-t3789793 but upon boot the phone stayed indefinitely on LineageOS's boot animation.

I tried flashing modified stock oreo from here: https://xdaforums.com/lg-v30/development/stock-t-mobile-lg-v30-stock-collection-t3917560 ("FullStock w/ Magisk") but upon boot the phone stayed indefinitely on the LG logo.

I haven't been able to download the 20o zip listed in the first post because my connection keeps dropping and Google Drive won't let me resume the download.

I'm going to try to download a 20p image from the OP I found on AFH. If I can't get that, or it doesn't work, are there any other ideas? Ideally, I'd like to run LineageOS, but since I have root I can also modify an oreo stock installation to be close to what I want.
[LG V30 Guides, News, & Discussion] ChazzMatt:
You HAVE to update to latest Oreo before installing an LOS-16 custom ROM or it will not work.

So why did you try to install a custom ROM while on Nougat?

You want H932 Oreo 20s:

https://xdaforums.com/lg-v30/development/stock-t-mobile-lg-v30-stock-collection-t3917560

Why are you messing with 20o? 20s is the last Oreo firmware.

PLEASE read the Root Sticky Guide before doing anything else. That's why it's there.

https://xdaforums.com/lg-v30/how-to/root-v30-t3927154

It covers basics about rooting and advice about custom ROMs.
[LG V30 Guides, News, & Discussion] eqroiueq:
But "Anybody running a custom rom like LOS or RR will have sound problems if you flash these." and I want to run LOS.

I was messing with 20o simply because it was on the original post. I would have updated from there.

One of the 20s ROMs in your link (FullStock w/Magisk) is what caused my phone to be stuck at the LG logo when I flashed it. However, I've tried again and it worked this time, and booted to system.

So now that I have 20s installed, will I have sound problems if I flash LineageOS?
[LG V30 Guides, News, & Discussion] zfk110:
after flashing this stock now I can't boot into TWRP, I'm sure I had TWRP installed on Laf because I was able to use power and volume down to get into it earlier, now when I do that it just showed me warring and wipe the phone., how do I get back TWRP again on the phone?
[LG V30 Guides, News, & Discussion] ChazzMatt:
As clearly stated in post number #1 of that thread, flashing that TWRP flashable zip will remove TWRP from your LAF partition. But you should still have TWRP on your recovery partition.

If you flashed Magisk befor rebooting, you can get to TWRP either through the Magisk Manager app or through the Recovery Reboot app, which I recommend..
[LG V30 Guides, News, & Discussion] zfk110:
I was so smart that I didn't flash Magisk as I normally do come back later on the flash Magisk so I dont have Magisk or root.
[LG V30 Guides, News, & Discussion] ChazzMatt:
So you didn't follow the Installation instructions in post #1?

Like flashing the Encryption Disabler and Root Checker Disabler?

You probably still have TWRP on your Recovery partition, but you'll have to get to it through the tricky Hardware Button Dance.

If you get to TWRP successfully, you'll need to also flash those other two files also, per the instructions.

It's also recommended you flash full stock TWRP flashable zip first before flashing the debloated version, with full reboot in between. Makes sure stuff works right.
[LG V30 Guides, News, & Discussion] zfk110:
I just flashed the stock without any of those files since I was thinking to go back to LineagoOS after flashing the latest stock because my finger print wasn't working under it, I tried this

Turn off your phone completely.

Press and hold Power and Volume Down button in the same time for several seconds until you see LG logo appear on the screen.

When the LG logo is displayed, release the Power button (keep pressing the Volume Down key) for a moment and then press it again.

This time, keep pressing on those buttons until your device boot up into Recovery Mode. When the device has enter Recovery Mode, then you can release both buttons.

but it will just wipe the data and go back to setup page.

I tried adb reboot recovery, it tries to boot into stock recovery and then it will go back to system again, I think I have to follow this guide and reflash the twrp again? so once I do get the twrp using this method? so how I can keep the TWRP on LAF after doing stock update on it?
[LG V30 Guides, News, & Discussion] ChazzMatt:
See important details below. Note the TWICE part.

8 sec Power + Vol-, and when it shuts off, release both,

immediatly press both again (at the same time),

and as soon as the LG V30 logo appears,

release power and press/hold it again.

Should get you to the factory reset menu, confirm twice with "yes" (navigate via vol/power buttons),

and TWRP should boot fine.

Might take a few tries to get the right timing for that.
[LG V30 Guides, News, & Discussion] zfk110:
I got it fixed, what I did

1st shut off the phone

press and hold volume up

plug USB cable connected to my PC

it took me into TWRP, I formatted the data

shut down the phone again within TWRP

then press and hold volume up

plug USB cable connected to my PC

it took me into TWRP, then I flashed those files with TWRP img on recovery.

Can I flash that same TWRP.img into LAF using TWRP? or flashing Twrp.img into recovery is good enough now?
[LG V30 Guides, News, & Discussion] ChazzMatt:
You can if you wish.
[LG V30 Guides, News, & Discussion] TheDannemand:
The way you got into TWRP is how you normally enter Download Mode, which means you actually have TWRP on laf. It seems that it was the TWRP on recovery you lost when you flashed the stock update. Just flash TWRP on recovery and you're good to go.
[LG V30 Guides, News, & Discussion] zfk110:
Hi, Matt I got phone up and running with [ROM]-[UN-Official]-Havoc-OS-2.4[9.0][H932]-[H930] Now finger print is working fine, but do you know any kernel made for H932 which I can flash with it?

LG stock Pie firmware needs newer Dev Patched LGUP to downgrade to Nougat than we used with Oreo. Users will need to use the Dev Patched LGUP in this post...

TEMPORARILY DOWNGRADE TO NOUGAT for TWRP Installation and Root

https://xdaforums.com/showpost.php?p=79971617&postcount=3

Post #1 references older Dev Patched LGUP which does not work to downgrade from T-mobile H932 Pie firmware.
[LG V30 Guides, News, & Discussion] Marmalade_Shaws:
I have ensured I am in 10d, rechecked and checked again. The flash for the H933 10h KDZ (LAF ONLY) completes without issue; however it does reboot at around 81% and then lingers indefinitely on the LG V30 logo. Crisis averted, however, no worries. I managed to force it back into download mode by holding VOL UP after the PWR + VOL DWN combo to push it into recovery. Once the logo disappears I held "volume up" after releasing both "volume down" and "power". Now I am stuck back at Nougat. I am unsure as how to proceed because I've followed the guide to the letter. Yet this one step before I can proceed past the flashing of the "LAF" file, it freezes and I am unable to boot into the OS or off. I'm afraid of pushing forward with the steps if it's frozen like this. Please advise. :confused:

Any help would be greatly appreciated. Thank you.
[LG V30 Guides, News, & Discussion] Marmalade_Shaws:
I'm afraid I have had a different experience. After rolling back to nougat, I allow it to flash the H933 LAF but it soft bricks (if that's what is doing): basically the phone in download mode reaches 100% before the LGUP application. It reboots and the LGUP finished flashing. After that it just hangs indefinitely on the LG V30 white logo. I am stuck on Nougat. If I am going to try the pull method before it finished like others are saying ("Pull it right after it flashes LAF, but am I not only flashing that?), when in the process do I do it? Also there is a LAFBAK, I'm thinking do I need that to? Why am I running into this error? All of my steps so far have followed the guide explicitly and I have not deviated from the guide whatsoever.

There's only one other piece of information I can think of that is any type of relevant. When I boot my phone doesn't just say V30, it says V30 "Thinq". Is that still fine? Is it a different version than others? Any help would be greatly appreciated.
[LG V30 Guides, News, & Discussion] ChazzMatt:
"ThinQ" boot up logo merely means you have Oreo or Pie, not Nougat. LG calls all V30 "ThinQ" starting with Oreo.

It's a stupid name to indicate the AI camera software introduced with Oreo.
[LG V30 Guides, News, & Discussion] Marmalade_Shaws:
My apologies, the logo is not there with Nougat, I just got so used to seeing it. My apologies. However my issue is still the same. If I attempt to flash the H93310h LAF file and that alone, and allow it to run course as the guide dictates it will still brick me and hang on the V30 logo.

I have been staring at the LG V30 logo for the last 10 minutes with no signs of proceeding, despite the LGUP flash completing successfully.
[LG V30 Guides, News, & Discussion] TheDannemand:
Couple of thoughts:

1) You did unlock the bootloader, right? Sorry, had to ask.

2) Do you use the LGUP linked in the opening post? You can use other versions of LGUP to roll back (and you MUST use the latest it you've been on Pie). But for the exploit steps (flashing H933 laf, etc) you MUST use the LGUP linked in the OP. That was established a few pages back when the first users tried to root after Pie.

3) Try a different cable and/or USB port.

4) Try downloading the H93310h KDZ again. Compare to the one you have to see if they're different.

I would start over, doing a complete flash of 10d in Refurbish mode (again, using the latest LGUP if you were ever on Pie). Then try again.

For my part, I didn't have to pull the cable. Others reported that they did.

That's all I got :o
[LG V30 Guides, News, & Discussion] Josh McGrath:
I had the same issue but it was because LAF was not being written by lgup so start all over . Sucks I know.

Make sure your sd card is fat16. Fat 32 seems to be hit or miss.

Make sure you have the correct and latest working TWRP file. If it's corrupted on download, it flashes the corrupted TWRP on upload and will try to boot into TWRP but since the phone thinks "I'm bulletproof and can't be messed with" it will assume it's valid and stock recovery and try to boot it forever

Also make sure you use the hardware buttons to boot into recovery immediately. Just in case . (Brief reply, sorry if I missed details) good luck :)
[LG V30 Guides, News, & Discussion] Marmalade_Shaws:
Hey quick update, and I do want to update in more detail which I will do later, but for now I have one final issue: So, gist of it? I rooted successfully and kept a second TWRP. But now I've lost download mode and am stranded without root or TWRP (just fastboot), on H93220o. Whenever I extract the firmware I cannot find the .image file everyone says but I find a laf_6.bin file. All I need is to get download mode back and I can do the procedure correctly this time. How do I flash the LAF file I need for H93220o and get download mode back so I can rewinde back to 10d Nougat? Whenever I try and initiate a fastboot boot twrp.img it will tell me 'too many links' and not boot in, and just boot back to OS.

Once this is done I'll detail a better update on where I personally went wrong just in case anyone makes the same mistake. It looks like a chunk of it was human error. Shouldn't have tried this when I hadn't slept properly.
