I haven't faced such problem. Check if you have the right rom for your model
[LG V30 Guides, News, & Discussion] ChazzMatt:
Why back to 10D? You need Oreo for some of the ROMs to work. Fingerprint or something.
[LG V30 Guides, News, & Discussion] Wolf Dragon:
Really? So I should flash back to an Oreo stock ROM in order to get the ROMs to work?
[LG V30 Guides, News, & Discussion] ChazzMatt:
One of the TWRP-FLASHABLE stock zip "ROMs".

Cool, I'll give it a shot. Shouldn't be too hard to find those for H932, haha. :3
[LG V30 Guides, News, & Discussion] Wolf Dragon:
Went to go do everything today, but through sheer carelessness on my part, I've ended up 9008-ing the phone. Crap.

Did a lot of research today but after finding lots of dead ends and [MENTION=7597529]manic4droid[/MENTION]'s instructions not working for me, I've resigned to hoping that uBreakiFix has a Octopus Box to fix this. My wallet weeps but it's of my own doing.
[LG V30 Guides, News, & Discussion] Josh McGrath:
Just call Tmo and tell them you don't know what happened, they'll send you another and you send that one back.

If you don't have ins, 20 bucks with slow shipping 5 to 7 days

"It just turned off and won't turn back on"

"It was doing a software update and just went black"

With insurance on your act: overnight and 5 bucks
[LG V30 Guides, News, & Discussion] Wolf Dragon:
Here's hoping this repair shop I'm going to today has an Octo box then, because I'm not sure if I can send in this phone since I didn't buy it straight through T-Mo, or does that not matter? I dunno, this is the first time I've properly screwed up and I've been pretty upset about it since last night.
[LG V30 Guides, News, & Discussion] Josh McGrath:
They don't care if you bought it from them or not. As long as it's the T-Mobile model 6t and no water or physical damage, you'll be good.
[LG V30 Guides, News, & Discussion] Opsectx:
I'm finding most of the h932 current versions of ROMs right now are broken and BS. At one point in Jan I could install and use LR, Lineage, pixel experience, RR, and potato. Currently I can only get older versions to install from Jan. Early Feb versions of RR and potato are still working. Currently running RR with no issues. But no other current h932 ROMs will make it past a boot logo.

Really wishing for the old days of Devs with true custom ROM releases. None of this cut copy paste and hope they work crap. But I have no room to complain much. I'm too busy programming for a living to mess with android dev work anymore.

Forogt to mention these were all pie ROMs I had working in Jan. And currently don't work now. Never flashed back to Oreo don't need finger print security.

H932 Hardbrick after flash all partitions except LAF. Phone complete flashing and never bootup again. (Bootloader Unlocked, Downgrade to 10D, H933 LAF flashed)
[LG V30 Guides, News, & Discussion] Josh McGrath:
No matter how it happened, you need a repair shop or a warranty replacement now.
[LG V30 Guides, News, & Discussion] JohnFawkes:
How did you flash all partitions?

---------- Post added at 02:00 AM ---------- Previous post was at 01:56 AM ----------

Not true. Go look at the 20r thread and see i just fixed about 6 devices I accidentally bricked with a bad kdz2zip zip
[LG V30 Guides, News, & Discussion] BrandonB1218:
It's possible this is fixable with John's fix but we need more information.

Did you flash over partitions like EFS or just what was in the kdz? When you say it doesn't boot up can you be more specific? Do you get a boot logo at all? Does it respond to adb commands at all?
[LG V30 Guides, News, & Discussion] chicofiebru:
Hey, a friend just told me he just flash H933 Firmware to H932 phone by mistake. Thats what happend.

---------- Post added at 10:52 PM ---------- Previous post was at 10:42 PM ----------

Now phone is on black screen. Won bootup. It appear as Modem 9008 in Device Manager. I think he just kill the phone.
[LG V30 Guides, News, & Discussion] BrandonB1218:
Yeah so your original reply was a lot more helpful than your edit. The OP says to flash just the h933 LAF, so you did it backwards. Either way if you have an octopus box as you mentioned, it can be fixed.
[LG V30 Guides, News, & Discussion] chicofiebru:
Thank you and sorry for all this mess. Im talking for a friend. I have the Octopus and a lot of other boxes. How can be possible to repair with no download mode? Can skype to better understand. Skype chicofiebru with gmail
[LG V30 Guides, News, & Discussion] Josh McGrath:
I don't know much about how those boxes work, but could you try the JTAG method?
[LG V30 Guides, News, & Discussion] ChazzMatt:
According to the 2nd version of the story, he either flashed all the H933 firmware or he flashed all the H933 firmware, except for LAF partition.

Either way, he did the exact opposite of what should be done. He was only supposed to flash the LAF partition of the H933 over the H932. You can't flash firmware from other variants over T-mobile H932, due to different RSA encryption. It will hard brick the phone. One of the few exceptions is the LAF partition, as it's not encrypted -- but when flashing you have to make sure the proper boxes are checked/unchecked before doing it.
[LG V30 Guides, News, & Discussion] reukiodo:
Thank you very much! I have two V30+ from T-Mobile on a BOGO and I've been successful in getting LOS on both of them now after following your instructions. I do need to mention that the steps don't specifically mention installing the LG drivers, but I figured that out anyway. I just thought it would be helpful to mention for newbies that they can get the drivers at https://www.lg.com/us/lgeai/Drivers/pages/mobile-drivers.html before the first step with LG UP.

I chose to follow the option of installing TWRP to LAF partition just in case.

I also chose not to boot into stock Oreo after flashing and instead immediately install LOS over stock Oreo and the super gapps package since our system partition is so large (6GB!). This was quite easy with swapping 2 uSD cards:

512MB FAT uSD: twrp flashing (didn't even need the Magisk or others)

8GB exFAT uSD: stock oreo zip, LOS16 zip, super gapps zip
[LG V30 Guides, News, & Discussion] Wolf Dragon:
Quick update from last week: T-Mobile refused to take it back claiming that it wasn't under warranty at all. I couldn't fight this one. Also, several repair shops I went to in my city didn't have an Octo box...and I live in a fairly huge city in the Midwestern US (nearly 3 million people) so I find it hard to believe. I had no other option than to return it to Amazon and I was only granted a partial refund because as it turned out, the first repair shop that I let look at my phone did not properly re-adhere the back glass, and it was loosened during shipping, so I lost out on nearly $300 because of a botched and failed repair.

I think it's safe to say that I feel pretty bad about this mistake as it is, but that was just salt on the wound. I've gone back to a Galaxy S8 for now, but considering that the T-Mobile variant (G950U) is essentially locked down tighter than Fort effing Knox...it looks like I'm stuck ruing the errors of my ways.
[LG V30 Guides, News, & Discussion] V30-H932S:
Custom rom bootloop issue

I'm using an LG V30-H932S, GSM unlocked.

I unlocked the bootloader and flashed twrp using lafsploit 1.5:

https://xdaforums.com/lg-v30/how-to/root-h932-lafploit-1-5-to-v20a-t3842550

I then flashed in this order:

1. lineage-16.0-20190213-UNOFFICIAL-h932.zip

2. Magisk v18.1

3. open_gapps pico

Then I wipe the cache/dalvik, and reboot the system.

After the reboot I experience a bootloop that I left upto 3 hours, with no sign of booting. Just the lineageos boot animation repeating.

Then I factory reset the phone, booted into TWRP. Then formatted the storage, and tried the process again--this time dirty flashing over:

H932 LINEAGE OS 15.1-20180927

15.1 boots, but after flashing 16 over--the same bootloop issue occurs.

I then flashed older versions of LOS 16 and only these 2 versions boot:

lineage-16.0-20181206-UNOFFICIAL-h932.zip

lineage-16.0-20181208-UNOFFICIAL-h932.zip

Flashing any version after, results in the bootlooping issue.

Also for LOS 15.1:

lineage-15.1-20180927-UNOFFICIAL-h932.zip - Boots

trebleized-lineage-15.1-20180928-UNOFFICIAL-h932.zip - Bootloops

Even for the versions of LOS 15.1 & 16; that do boot, there are issues:

FINGERPRINT NOT DETECTED

AFTER ENCRYPTION, TWRP CANNOT BE DECRYPTED WITH PASSWORD

NETFLIX ERROR 1101

SPEAKER IS VERY QUIET

VIBRATION IS WEAK / NOTIFICATIONS ARE NOT PUSHED

I have tried various ROMS, here are the ones with a bootloop issue:

LiquidRemix 10.0

Havoc-OS 9.0

DOT OS 9.0

Ones without, but with the same issues with working LOS versions:

Ressurection Remix 8.1

The issue with TWRP not accepting the OS password for decrypting, was also present with LOS 15.1 on an LG V20 unlocked with LAFSPLOIT.

Any help will be much appreciated.
[LG V30 Guides, News, & Discussion] Josh McGrath:
Well, for one of the very minor issues, Netflix isn't working on logins right now unless it's been fixed in the past 30 mins. Netflix confirmed for me

Second, you need to flash the Oreo firmware from OP before you go to those other steps and jump roms
[LG V30 Guides, News, & Discussion] mattgyver:
Don't spam the boards. Forum Rule 5 (post topic only once).. You posted the exact same post in the lineage16 thread... Neither thread, though, is a general help thread. Your issue doesn't really pertain to either thread. It should have been asked in the v30 q&a forum..
[LG V30 Guides, News, & Discussion] ChazzMatt:
Agreed. Both this H932-specific thread and the WTF thread are for bootloader unlock, TWRP installation and root of the V30 series.

In WTF, towards the end, I do give links to update to newer stock firmware via TWRP-flashable zips helpfully provided by some devs... But neither thread is about installing custom ROMs. Even any questions about stock firmware KDZ (for example, like whether DTS 3D stereo is available on certain builds) or TWRP-flashable zips should asked in those threads or separate Q&A post.
[LG V30 Guides, News, & Discussion] ReddotCleaner:
Is there any other way to root my h932 and install twrp?
[LG V30 Guides, News, & Discussion] mattgyver:
Absolutely. read the OP.

If you are on stock oreo OTA, you need to downgrade to 10d first (there are instructions about that, too).
[LG V30 Guides, News, & Discussion] ChazzMatt:
If you mean any other way than the instructions in this thread, no. Not for U.S. T-MOBILE H932.
[LG V30 Guides, News, & Discussion] alfalfanater:
I know the title says "up to v20k", so does this method not work with the latest v20r update?

And thanks for all the work and effort you put into making this possible btw!
[LG V30 Guides, News, & Discussion] ChazzMatt:
Because the dev can't predict ahead if time if LG will change something so it doesn't work with future updates. He just hasn't updated the title to most recent releases.

Yes it still works.
[LG V30 Guides, News, & Discussion] conbak49:
Are all H932s the same? I have one on the way from ebay which is advertised as a "GSM world phone" with no mention of T-mobile. I want to make sure I follow the right procedure for rooting it.

Thanks
[LG V30 Guides, News, & Discussion] mattgyver:
All H932s are V30s, but not all V30s are H932. Be very careful when you get it. Flashing non-H932 stuff to an H932 (and vice versa - H932 files to non-H932) results in an expensive paperweight!
[LG V30 Guides, News, & Discussion] ChazzMatt:
NO, all H932 are not the same. There are:

U.S. T-mobile H932SV and the

Claro (Puerto Rico carrier) H932PR.

The most common is the U.S. T-mobile H932SV and most people just call it "H932", but

a few people in this forum actually have the H932PR

-- which is totally different from the U.S. T-mobile H932SV.

Yet, BOTH are "H932". Don't ask me why, ask LG. :rolleyes: U.S. T-mobile H932SV has different RSA encryption from all other V30 variants.

Unlike the U.S. T-mobile H932SV, the H932PR CAN be Frankensteined and CAN use WTF:

Again, this is NOT NOT NOT the U.S. T-mobile H932SV. Do NOT try that with U.S. T-mobile H932 or you will brick your phone!

The "GSM world phone" part is curious, because if it's a T-mobile H932, then that means it's carrier unlocked -- which can be done but is sometimes problematic to keep that way. Whereas H932PR CAN easily be carrier unlocked by Frankensteining to another variant like US998.

Do you have a link to the eBay description?
[LG V30 Guides, News, & Discussion] mattgyver:
:eek: didn't know there was a second variant....
[LG V30 Guides, News, & Discussion] TheDannemand:
A technicality: Not all T-Mobile V30 models are H932SV. That's just the Silver 64GB version. My Black T-Mobile V30+ is H932UBK (U=128GB, BK=Black). And I believe there was a regular 64GB Black H932BK as well (I could be wrong about that).
[LG V30 Guides, News, & Discussion] ChazzMatt:
H932PR

doesn't have LTE band 71 (in spite of some sites showing it -- they are confused or ignorant). That's the next question everyone asks. It's just phone for Puerto Rico Claro.

Still T-mobile (or Deutsche Telekom) must have some kind of financial equity or something with Claro -- for them both to have the "H932" model number.

---------- Post added at 10:52 PM ---------- Previous post was at 10:35 PM ----------

You are correct that the 128GB T-mobile H932 has U. I didn't know there was a black 64GB, however.
[LG V30 Guides, News, & Discussion] conbak49:
I couldn't figure out how to share a link w/o sharing personal info. Seller is Soonersoft.

I may have to wait till I get the phone to be able to confirm the model # as I don't see anything more than H932 in the listing. It does actually list the network as T-mobile, but in the description it says "NETWORK IS NOT T-MOBILE BUT IT IS UNLOCKED". I should be able to find the exact model # on "About phone" menu correct?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Found it.
[LG V30 Guides, News, & Discussion] conbak49:
That's it! Can you tell anything about the model # from the listing?
[LG V30 Guides, News, & Discussion] ChazzMatt:
No. It's either a carrier unlocked T-Mobile H932 or it's a Frankenstein converted Claro H932 to another variant like US998.

The fact it says T-Mobile and "not T-Mobile" doesn't surprise me as eBay templates are unforgiving. They sometimes make you list stuff that's not quite actuate or doesn't make sense. You then try to clarify in the listing description. So, it could be either.
[LG V30 Guides, News, & Discussion] conbak49:
So how do I accurately determine the model once I have the phone in hand?

And thanks for your help! (I'll tap Thanks on your posts as well)
[LG V30 Guides, News, & Discussion] Josh McGrath:
Personally I would put a Sim in it, make a call. Hang up then immediately call T-Mobile and ask them what model they show (specifically ask for full model) and also log in on your act and check there too.

If they show a Tmo h932, then it's a win win situation cause if you brick it while rooting, they'll send you a warranty exchange (5 bucks with ins 20 without) and that new phone you do get will be a 100pct verified Tmo h932 without question.
[LG V30 Guides, News, & Discussion] ChazzMatt:
In About Phone should help. And also running the real IMEI will help. I doubt the one in the picture is what they're actually sending you. We'll see.
[LG V30 Guides, News, & Discussion] AsItLies:
What do you think Matt? Is it possible the IMEI in the phone (any aftermarket phone) could be spoofed? A stolen IMEI? If that were the case - then it could be an IMEI from a different version, but just 'Clean'. Then converted to us998 and the seller sells it as 'unlocked' thinking it will work on all carriers?

I mean, there has to be a good reason they say you should never give out your IMEI to anyone?

Cheers
[LG V30 Guides, News, & Discussion] conbak49:
Actually I bought it to activate on Cricket since it is supposed to be unlocked for GSM carriers. Would this strategy work for that scenario (make a call and check with Cricket - not sure how one does that - and see what they report?). Would T-mo warranty a phone this long after it's release and if I'm buying it used from an ebay seller?

Hadn't thought about the IMEI being different from what's pictured, but that makes sense since they are selling 4 of these with that same posting. They couldn't all have the same IMEI. Is there a way to do an IMEI check (when I get the phone) that would accurately identify the model #? I couldn't find a site that provided this information.
[LG V30 Guides, News, & Discussion] AsItLies:
This is a link to LG IMEI Checker. It gives mfg date, original buyer (like Sprint etc) and if the IMEI is clean etc etc.

First thing I do with an LG phone is check that link.

Cheers
[LG V30 Guides, News, & Discussion] conbak49:
Thanks much! Wasn't aware of this resource. The IMEI for the phone pictured (which may not be the actual phone I receive) indicates it is an H932SV that was sold to T-mo. So if the one I get is the same, than it looks like lafploit will be the way to go for rooting.
[LG V30 Guides, News, & Discussion] TheDannemand:
My point was more that the "SV" in H932SV only means it's the Silver model. And according to this LG page there is also a T-Mobile Black H932BK (which I wasn't sure about till I googled it) in addition to the 128GB Black H932UBK (which I WAS sure about because I own it).

So, we have H932SV, H932BK and H932UBK, all of which are "true" T-Mobile models -- i.e. with their own RSA certs, easily bricked, hard to SIM unlock, and all that good stuff. And then the H932PR which is just a H932 in name -- and much better off for it, as it can be Frankenphoned and WTF'ed.

[MENTION=4631519]conbak49[/MENTION]: That picture posted by ChazzMatt looks completely like my wife's T-Mobile H932SV. Of course that's no guarantee that what you'll receive is the same (as Chazz wrote, it likely is NOT). But considering that T-Mobile sold a good number of these on various deals (including BOGO stacked with a $400 LG coupon) I think it is much more likely that you'll receive a H932SV than the rarer H932PR.
[LG V30 Guides, News, & Discussion] conbak49:
Sounds about right.
[LG V30 Guides, News, & Discussion] conbak49:
I am waiting on what I think is a carrier unlocked H932 (see my other posts) and in preparation have been reading through this thread. Is there anything in this rooting process that would mess with the phone's carrier unlocked status? I ask because I plan to use this phone on Cricket and not T-mo.

Thanks
[LG V30 Guides, News, & Discussion] ChazzMatt:
For some people, installing updates mess with the H932's carrier's unlocked status. But that's carrier unlocked through the T-mobile app. I don't know how this one is unlocked.
[LG V30 Guides, News, & Discussion] conbak49:
I'll check in here before I do anything!
[LG V30 Guides, News, & Discussion] conbak49:
Phone arrived this evening. Per LG's IMEI checker it is an H932SV. The phone itself just says it is an LG-H932, but it had a T-mo boot animation. Sounds like it's safe to assume it's a T-mo H932?

It had no problem with my Cricket SIM. I guess that mean the phone really is carrier unlocked.

OEM unlock is not switched on so I'm assuming I have to do that first step of unlocking. Phone is on 20o, but says there is a security update of 167.3 mb available. Should I take that before starting the root process?

Anything else I need to be aware of before I jump in to this procesd?

Thanks
[LG V30 Guides, News, & Discussion] ChazzMatt:
No need to take the security update since the first thing you'll do is downgrade back to Nougat (temporarily).

You can update to latest T-Mobile Oreo via TWRP-FLASHABLE zip after bootloader unlock and root.
[LG V30 Guides, News, & Discussion] conbak49:
Another question: do I need to have USB debugging on before doing bootloader unlock?

And do i just open a command prompt as administrator and type in "fastboot oem unlock"? Do I need to navigate to a specific directory before sending the command?
[LG V30 Guides, News, & Discussion] TheDannemand:
You need to run fastboot oem unlock while in fastboot mode. It's the second step in the procedure:

This is a rather sensitive procedure, and you really want to follow it to the dot. Don't assume anything, just do exactly as it says. Keep it open on a PC so you can easily copy commands etc.

I'll be interested to hear what happens with your SIM unlock after flashing 10d in Refurbish mode. I haven't rooted my own H932 yet. Hanging on to my 2-year warranty (and my time) until I need root for something -- or until an ARB1 update arrives that would prevent me from downgrading. Good luck!
[LG V30 Guides, News, & Discussion] conbak49:
Thanks. I understand that the phone needs to be in fastboot mode. My question is about the Windows side. To run that command in Windows do I just open a command prompt and send the command while the phone is in fastboot mode?
[LG V30 Guides, News, & Discussion] TheDannemand:
Oh, I see. I am sorry I misunderstood you.

As mentioned in the Prerequisites, you need to have ADB / fastboot environment installed on the PC, which you can get from Google's SDK Platform Tools. Try this download link or this page.

Once installed, use ADB in the OS to verify it is working, before you go to fastboot mode: Enable USB Debugging (even if just temporarily), connect the phone (say yes to any prompts), open a command prompt in the folder where you installed the platform tools, and type ADB devices to verify it's working. Google ADB setup if you have problems, plenty of guides about it.
[LG V30 Guides, News, & Discussion] conbak49:
That's exactly what I needed to know. ADB's working. Gonna give the process a shot in the morning when I'm more awake. Thanks for the help.
[LG V30 Guides, News, & Discussion] Josh McGrath:
Make sure that you format your SD card to fat 16. For example, I used a 200gb card and formatted into a single 500mb partition of FAT16.

It's easier to just cut/paste the commands from Runningnak3d's own post.
[LG V30 Guides, News, & Discussion] conbak49:
Yup, I've got the SD formatted to a 2gb FAT 16 partition.

Just unlocked the bootloader successfully and carrier unlocked survived that. On to the next two steps...

Carrier unlocked survived downgrade to 10d...

And carrier unlock survived laf change (still have connection to Cricket)

Gonna try step 2/FWUL stuff later this afternoon

So ive modded lots of phones in the past but i thought the big problem with this phone was it has no fastboot. If thats the case, and it appears to be because my phone wont boot into fastboot using the method described or by using "adb reboot fastboot" , how do i get this phone into fastboot to unlock the bootloader? Im pretty sure i missed something :/
[LG V30 Guides, News, & Discussion] ChazzMatt:
It has some fastboot. All the important fastboot flash commands have been removed.

So how do i get to fastboot? can i run fastboot commands from the factory reset screen? It just reboots and boots to the os when i try. Do i need to downgrade first?
[LG V30 Guides, News, & Discussion] ChazzMatt:
No. You need to follow the directions in order.

Point #2 tells you how to get into fastboot mode.
[LG V30 Guides, News, & Discussion] jprosek:
Right, It just reboots. So i tried connecting my phone to the computer and used adb reboot fastboot. Same thing. It shows the v30 screen flickers reboots again and boots into os. If i hold vol- and insert usb i just get the v30thinq screen over and over until i let go of vol- and then it boots to os. Ive never not been able to get into fastboot before especially with debugging enabled.
