Yes, laf is reading your SD card alright. But you have to rename the TWRP file to just "twrp.img" exactly.

Error message

Hello, when trying to power up into twrp I get an error message. I sent you a PM as well. Was wondering if you or anyone else could help me out. Thank you for your time
[LG V30 Guides, News, & Discussion] Josh McGrath:
A little more detail on the problem would be nice... No one will be able to help with that little info
[LG V30 Guides, News, & Discussion] b0n3head:
Sorry, was trying to go through it again to get the image. Didn't expect such a quick response.

After doing the power on holding volume down and selecting yes both times, I get the following message...

"Your device has failed a routine safety check and will not boot

This may be a temporary problem. If this message occurs repeatedly, visit this link on another device and refer to the red case

g.co/ABH"

I followed all the steps as closely as possible, tried both fat32 and fat16 formats for the SD, the SD card is read fine when running the commands in Linux. I'm thinking maybe the LAF portion wasn't done correctly? As I was a little confused with the last statement for the following...

Choose partition DL again, and this time pick the H932 10d KDZ.

Select all partitions except laf. If you forget to uncheck laf, you will have to do this all over again.

When it completes, it will reboot your phone.

Go back into download mode. This time you will be running the H933 laf, and we can continue with PART 2.

I did try without doing h933 LAF a second time and with doing it a second time. No luck either way
[LG V30 Guides, News, & Discussion] Josh McGrath:
Short story? You're pretty much screwed. You did not unlock the bootloader before starting the process. There is no way that I've seen to get back in to unlock it.

Can you get into twrp or stock recovery or even fastboot at all? Or download mode?
[LG V30 Guides, News, & Discussion] b0n3head:
Download mode, stock recovery, and fastboot all work fine. Just unable to load into twrp

I will note that Everytime I try fastboot oem unlock, nothing happens on my phone and adb just stays on < waiting for device >

Should I try reinstalling the adb files?
[LG V30 Guides, News, & Discussion] Josh McGrath:
Okay so it's not as bad as I thought. I thought you had lost DL mode as well. In this case, it's a lucky break you didn't lose stock recovery.

Start from scratch and factory reset it or flash the stock 10d via lgup.

On my v30, I don't know why, but I had to enable adb debugging to do anything even in fastboot so do that first just in case.

Then unlock the bootloader. If it doesn't do anything, do fastboot devices and if still nothing go to device manager and see what it shows for the v30 and report back.

I would say yes, reinstall adb and try a different cable.

Edit:******if you can't unlock the bootloader, DO NOT proceed or you will most likely have a nice paperweight! You got very lucky this time******
[LG V30 Guides, News, & Discussion] b0n3head:
Ok, I'll try that ASAP. Thank you very much, It's greatly appreciated! I will edit this post with an update once I get to try it.

EDIT: so I was able to successfully unlock bootloader after installing adb again. Now just to clarify, will these be the following steps?

- install h932 LAF partition

- install install remaining partitions with h932 10d

- run fwul

- load lglaf shell

- run exec command then Ctrl poff

- boot to twrp

Edit 2: I was able to successfully complete the procedure and rooted the phone.

@ Josh, thank you very much for the help and quick response, it's greatly appreciated.

[MENTION=3167089]runningnak3d[/MENTION], thanks a bunch for the great and thorough guide! As feedback, the only part that kinda threw me off was when doing the LAF. After partitioning the remaining parts, it mentions to go back to download mode and will be running h933 LAF. I was thinking it meant to run the LAF partition a 2nd time. Other than that, great job!

[MENTION=9350973]All[/MENTION] others that contributed, great thanks to you all!

New Problem

So I flashed that file and got the OTA firmware update screen and all. Phone rebooted, show the glowing erasing ring for a split second then i got the broken android picture with exclamation over it's belly and "error!" below it....am i royally screwed now?

I mean my phone works fine but i WOULD like to rom this puppy.
[LG V30 Guides, News, & Discussion] TheDannemand:
But see if you now have download mode back. That is the whole purpose of flashing that OTA update. If you have download mode, you can flash a full KDZ with LGUP, and you're good to go again.
[LG V30 Guides, News, & Discussion] Cothirteen:

Thanks for replying!! The flash didn't work so I don't have download mode.
[LG V30 Guides, News, & Discussion] TheDannemand:
I see. Do you have root? If so you could flash TWRP to the recovery partition using dd commands or flashify.

Just a thought...
[LG V30 Guides, News, & Discussion] Cothirteen:
I dont :( I never got that far and was hoping flashing that OTA would work. I've been trying to find the OTA file for the latest security update (March one) but no luck.

The flash seems to happen ok...shows that FOTA screen, goes through the "android updating" part..restarts and shows the erasing glowing circle real quick then the broken laying down android. So it appears to not go through the process fully.
[LG V30 Guides, News, & Discussion] TheDannemand:
I'm sure you already posted it earlier, but could you describe again how far you got, the symptoms of failure, what happens when you try to enter download mode, and what happens if you try a Master Reset (button dance)?

I am puzzled how you lost download mode unless you deliberately flashed TWRP to laf. And it sounds like you still have stock recovery, which means it should be possible to force flash the OTA - although I haven't done that myself, but others here posted how they did it.

I'll be out all day, but others here may be able to help, and in any case will I look again this weekend.
[LG V30 Guides, News, & Discussion] drewtheis:
I hate to bother you guys but I've tried looking everywhere so I'm just going to assume there is no arb 1 on any firmware?
[LG V30 Guides, News, & Discussion] mattgyver:
Not yet.. I'm sure when it happens, there will be threads/posts in big red letters saying not to upgrade past a certain point.
[LG V30 Guides, News, & Discussion] Cothirteen:
First off thank you for trying to help!! Second of all I am regretting not getting an easier phone to root lol...ive rooted a gazillion phones so a little embarrassed I goofed on this!

So what I did not do first was this:

"If you aren't on 10d, let's get 10d onto your phone. Put your phone into download mode:

With the phone off, hold vol up, and plug in the USB cable that is connected to your PC.

Launch LG UP. Open the folder that you unzipped (in the proper location), and double click LG UP.

It should detect your phone, and will show what version is currently installed.

If you have something greater than 10d, then select "Refurbish", and choose the 10d KDZ.

Click start and let it flash the entire thing.

When it is done, your phone will reboot back into the OS.

Power the phone off -- you now have 10d, and can continue..."

I was accidentally past that part in my browser and saw the following instructions instead:

"PROCEDURE PART 1: Getting a working LAF onto your phone

Make sure you are on version 10d. Again, check in Software Info / Software Version if you are unsure.

Boot to download mode

In LG UP, choose partition DL.

Pick the H933 10h KDZ

Click start

You will be given a list of partitions to flash, ONLY check laf

Click start

You will get a warning about additional modified partitions (cache, OP, userdata) -- ignore it, and click OK.

Click OK and it will start flashing.

Once the flash completes, your phone will reboot into the OS. Just power off, and go back into download mode.

Choose partition DL again, and this time pick the H932 10d KDZ.

Select all partitions except laf. If you forget to uncheck laf, you will have to do this all over again.

When it completes, it will reboot your phone.

Go back into download mode. This time you will be running the H933 laf, and we can continue with PART 2"

So as you can imagine since I didn't downgrade and went on to the partition stuff prematurely it wiped out download mode....and who knows what else!!

When i try to boot into download mode it shows the first download mode screen with the blue dots but never goes into the screen (which I got the very first time before goofing stuff up) with the recycle-esque arrows and progress bar. It just reboots after that first screen and goes into the OS normally.

I can seemingly flash the OTA fine and shows android is processing the update but then goes to the error screen as reported previously. When I am in the OS it still shows the latest ota update (the march one i believe) I was trying to find the latest one to flash since the one I found was from october I think. (instructions say it should still work as long as i am not on anything prior to oct)

Ok...i think that's everything. If anyone has any wisdom to share it would be much appreciated!! Oh and I have done several factory resets and the issue persists. I think the partition with the download mode is blown away or something...
[LG V30 Guides, News, & Discussion] TheDannemand:
Thank you for the description. So you didn't downgrade to 10d, but you completed flashing H933 laf with LGUP. Is that correctly understood?

Were you then able to complete PART 1 with the flashing of H932 10d (except laf)?

It sounds like the H933 laf is there if the blue dots show up when you try to boot into download mode.

Did you unlock the bootloader (fastboot oem unlock)?

If NOT, then I am guessing that the H933 laf refuses to boot because it isn't properly signed for your H932. And if so, unlocking the bootloader now may be all you need to complete the rest of the procedure.

Either way should force flashing OTA restore your H932 laf. But I can see how an OTA from Oct 2018 might not work if you're currently on 20s from Mar 2019, or on 10d (because you completed the step where you flash 10d except laf). You need to get that latest OTA. Look around here, both in this thread and other V30 threads. I have to believe someone posted it.

But first thing make sure that bootloader is unlocked. If not, that's your problem right there. And having a working OS (Developer Options > Enable OEM Unlock) you should still be able to do that, if you haven't already.

Good luck, buddy! :fingers-crossed:
[LG V30 Guides, News, & Discussion] Cothirteen:
Yep my bootloader is still unlocked...so maaaaybeeee if I am able to find that march ota file that may do the trick. Otherwise I guess I am just unrootable at the moment. Thanks for the insight!
[LG V30 Guides, News, & Discussion] TheDannemand:
So when you say your bootloader is "still unlocked" you mean you unlocked it with "fastboot oem unlock" in fastboot mode, right? I am sure you did, given your past rooting experience. I only ask because that step is absolutely crucial.

I don't think your phone is irreversible screwed, but if you cannot get it working with OTA, try and ping the OP with a post containing [MENTION=1089164]runningfullyclothed[/MENTION] (using his actual username). He has been incredibly helpful, and continues to be, but I don't want to ping him unnecessarily.
[LG V30 Guides, News, & Discussion] Cothirteen:
Yep...that's the method I used. Ha..no worries..it's good to get ALL the info. I'm an IT guy and hate when clients don't tell me everything I need to know so I am left assuming things :)

Ok..I will send that user a message...i hope if i can find the latest OTA or if that user has some insight I may be able to start over!
[LG V30 Guides, News, & Discussion] TheDannemand:
I would ping him in this thread instead of PM. But only after trying to locate and force flash that OTA, if that doesn't solve it.
[LG V30 Guides, News, & Discussion] Cothirteen:
Ive actually been looking for that since yesterday and either im not using the right search words or i just can't find it...so pinging may be in my future. thanks :)

I was on the latest stock build and security ota before downgrading.
[LG V30 Guides, News, & Discussion] TheDannemand:
Make sure you install FullStock 20s (as ZIP of course, not as KDZ) before trying other Oreo or Pie custom ROMs. This updates modem, firmware etc from the 10d used during root, and is needed by the custom ROMs.
[LG V30 Guides, News, & Discussion] BROKEN1981:
After rooting, you need to flash latest stock firmware before using a custom ROM.

[LG V30 Guides, News, & Discussion] ChazzMatt:
Well, you will have Pie regardless of custom ROMs. It's coming for all V30.

Second there's lots of "development" going on that has nothing to do with custom ROMs. Many prefer to run rooted stock firmware and customize what they want while having rock solid stability. (I ran custom ROMs on all my previous Android devices, phones and tablets, since 2011. I've written Guides on custom ROMs so I have utmost respect for ROM devs and their hard work.) I'm just stating there's an alternative to custom ROMs where if you are rooted, you can add mods and customize what you want yourself. For this phone, this is some of what I've chosen to do.

edExposed allows tons of Xposed modules to be used while passing Safety Net. Surely you know about Xposed modules? The most famous of which is probably Gravity Box, which gives you custom ROM features. Some don't work with stock LG firmware but for me the status bar icons and audio GUI do.

(Ignore the LP notation. The categories are the same in Oreo and Pie. I just can't find a comprehensive Oreo screenshot like this.)

There are lots of other Xposed modules.

You did the right thing rooting your H932 at the time you did: Once Pie arrives on the phone, it will be too late as it will probably increment ARB and prevent rolling back to previous OS versions. Being rooted, you can flash Pie from TWRP and avoid being locked down.

It is absolutely true what you mentioned earlier that H932 is not a developer friendly phone, even less so than other V30 models: Qualcom, LG and T-Mobile each successively did their best to prevent you from rooting. And if you manage to root it despite that, they have included a bunch of different tracking services and apps that will record that fact and phone home to tell mum what a bad boy you have been.

But guess what, due to some spectacular oversights by LG, all V30 models except H932 can be rooted despite that. And thanks to a herculean effort by runningnak3d (and the sacrifices of several owners) even this super locked down H932 can be rooted as well, along with many other LG models which he broke free.

But BECAUSE they're not developer friendly, they require particular attention to the exact steps of the rooting procedure, making sure every t is crossed and i is dotted. That also includes studying the root thread for relevant recent discussion. Have a plan BEFORE you start the process.

The fact that you have to flash the latest stock ROM in order to ensure updated modem and firmware before going to recent custom ROMs has been described many times in this thread. It's not a big step and it makes perfect sense considering we use a way old OS version in order to run the exploit.

After that it's pretty smooth sailing. But this is STILL not like the good old days of Nexus 5: Flash a ROM that doesn't have specific H932 support, re-lock the bootloader without being completely stock first -- or various other missteps -- can all bork your phone.

Once again, you did well here. Just keep reading to stay out of trouble. That's why we have this forum, right?

Do the last step in Post #3, CLEANING UP: flash the H932 laf ZIP in TWRP. That should get your download mode back.

I assume the reason you lost download mode is because you performed the optional step in Post #3 of flashing TWRP to your laf partition, which is completely legit. OTOH if you have neither download mode nor TWRP, that's another matter. In that case, please post more details of what you did, what happened, and what the symptoms of failure are.

Thanks for the quick response. I followed all the steps carefully and got TWRP working but then I tried go flash the Magisk-v18.0/H93220s_FullStock_wMagisk (SUCCESS), no-verity-opt-encrypt-6.0/lg-rctd-disabler-1.0 (FAILED) via TWRP. I rebooted the phone to try again and then it showed encryption error and a reset phone button. I click reset phone and it booted the stock OS (H93220s) and then I lost Download mode and I am assuming TWRP. I tried the Download recovery guide but it performs the upgrade/downgrade but then I see the error screen and when I restart the phone it goes back to the stock OS.

Please advise and thanks to everyone for their help with this :)
