I extracted the LAF6bin and renamed it to LAF.img and tried to flash but permission denied. Was worth a shot.

dd if=/sdcard/laf.img of=/dev/block/bootdevice/by-name/laf

---------- Post added at 07:56 PM ---------- Previous post was at 07:52 PM ----------

Thanks my issue is that I overlooked steps, I never flashed 10d Rom I flashed 10d LAF. My mistake totally. Im still on 20k because I never made through the process correctly. So I have been trying to restore download mode so I can follow the process correctly. No download mode equal no recovery so I can't sideload.
[LG V30 Guides, News, & Discussion] SweetwaterBurns:
So you lost stock recovery too? That seems odd since flashing twrp doesn't get rid of download mode. Weird it works the other way.

I only have 64gb SD Cards and I can't format them to fat16.... this is getting frustrating.
[LG V30 Guides, News, & Discussion] lowkeyst4tus:
4gb or lower will, partition it if you can..
[LG V30 Guides, News, & Discussion] runningnak3d:
You can use FAT32. I need to update the first post.

H933 laf has FAT32 support .. didn't know that when I wrote this. H918 laf didn't, and I just assumed. And you know what happens when you assume.

Does anyone know of a cheap site for Sim unlock? The cheapest one I found is $70.. the one tmo recommend $150.. I'm trying to pay around $50.. not to close to 60, cheaper than 50 ok.. ?.. not a random site from Google.. one you guys actually used and can confirm work..

Alright thanks a lot :) Now i just gotta install linux and i'll be rooting. I only rooted my htc one m8 a couple years ago very easily, so doing this is basically a first time. Your work here is great.
[LG V30 Guides, News, & Discussion] runningnak3d:
Just use Rufus to burn the ISO onto the stick. Then you just have to figure out how to get your PC to boot from it.

For me, I have to tap f2, and it gives me a boot menu.

However, if your PC is setup to boot from UEFI exclusively, I think you will need to enable CCM (old school BIOS emulation).

All of this is in the FWUL thread, in case I am missing anything.

[LG V30 Guides, News, & Discussion] ewatt99:
The process was pretty easy actually, but I haven't been able to get twrp installed. I did the button combo right, but it just erases my phone and restarts. I might have to reformat the sd card and try the files again.
[LG V30 Guides, News, & Discussion] Josh McGrath:
Twrp didn't get installed. It should boot into twrp after the yes/no questions instead of resetting
[LG V30 Guides, News, & Discussion] Addiso:
A common mistake I've seen was twrp being renamed to "twrp.img" when it should just be "twrp", just a thought since it's already a IMG file. Made that mistake in the past with other phones lol
[LG V30 Guides, News, & Discussion] ewatt99:
My file is named just twrp with the .Img as the file. Sd card was also fat32 as said to be possible from Brian. I'm going to try fat16 and see if it does anything.
[LG V30 Guides, News, & Discussion] maddangerous:
I'm running into the same situation. Step one goes fine with the LAF partition, I get booted into FWUL, run ./lglaf.py, run the commands, and upon rebooting into recovery to get to twrp... it just erases the phone, no twrp.

Suggestions?

SD card is a 16 GB sandisk, formatted to FAT32 and the partition has been sized to 2048 MB. I'm also using a usb 2.0 connection rather than 3, and using the cable that came with my phone.

Edit: Ok, so I forgot I switched cables, wasn't using the stock cable at first. I'm gonna start over from the beginning, using the stock cable. Also switched USB ports.

Edit 2: alright, took my time with it, still no twrp, it just keeps factory resetting. I'm gonna set this aside until tomorrow.
[LG V30 Guides, News, & Discussion] mattgyver:
Are you copy/pasting the code that goes into the FWUL terminal? If not, are you reading the code/commands from a phone screen or a computer screen. Did you remember TWO SPACES after !EXEC?

Suggestion to all: when in FWUL, take time to make sure you're connected to the internet, and open this thread in Firefox. Then you can copy/paste the !EXEC command. Then you don't have to worry about the commands being wrong!
[LG V30 Guides, News, & Discussion] mattgyver:
It's not really a mistake, so much as Windows hiding file extensions by default. Typical users don't care, but with something like this, like you said "it's just named TWRP". It's not. It's named twrp.img but windows doesn't show you the.img.

Stupid windows....
[LG V30 Guides, News, & Discussion] ChazzMatt:
Also mentioned extensively in my WTF guide -- ensuring you have known Windows extension visible -- because of issues we had with in the Droid Turbo forum. Here in the V30 forum, I've frequently asked for screenshots and that's one of the reasons. In fact, in my WTF Trouble Shooting Tips, it's #2:

Because in WTF, you are flashing TWRP from the ADB folder. So, you need to make sure the extensions are visible or you often will not TYPE the correct file name. Or you end up with TWRP.img.IMG, where the real file extension is hidden and they thought it needed to be TWRP.img.

That's almost the first thing I do when I sit down at a new computer, make known extensions visible. I hate Microsoft trying to hide my file extensions. This is also how malware gets on computers, thanks to Microsoft's stupidity. Something seemingly named "naked.jpg" (oh, what's this, let's click on it!) -- but it's REALLY naked.jpg.EXE. Because Microsoft hid the file extension. :rolleyes:
[LG V30 Guides, News, & Discussion] runningnak3d:
I am going to dedicate a big chunk of my time this weekend getting signed partitions flashing with LGLAF. Once that happens, we can ditch LG UP entirely, and everything can be done from FWUL. That won't magically allow rooting of any LG phone, but it will allow us to flash individual partitions without LG UPs security measure of wanting to flash additional partitions that are different in the KDZ than what is on the phone -- for example, flashing the H933 laf onto the H932, and it wanting to flash cache, OP, and userdata.

What is strange is that I have done packet captures of LG UP flashing a KDZ, and my implementation of LGLAF flashing a KDZ, and they packet captures are identical.
[LG V30 Guides, News, & Discussion] maddangerous:
Yes, I went the copy & paste route.

I did go from step one again, no dice. Double-checked via adb that the bootloader was registered as unlocked, etc. I may try a different SD card, but I don't have a smaller card that I know of.
[LG V30 Guides, News, & Discussion] [Cruzer]:
I'm having the same issue... reflashed laf partition twice.. ran FWUL on 3 computers and I still can't get TWRP on the phone. is there anyway to check what ./lglaf.py is seeing as what/where the SD card is. like doing a list/ls of the directory make sure same naming convention. I run the ( copy paste ) command and then wait 10 minutes.. Then run !CTRL POFF but no matter what seems like its not dd'ing the volume. I also formatted microsd card FAT16 4gb size.. then FAT32.. and renamed file twrp.img

Thanks

Richie C.
[LG V30 Guides, News, & Discussion] mattgyver:
The naming convention doesn't make a difference. If you have an SD card inserted, it will be at /storage/external_SD.

When you run the !EXEC command, how much time passes between when you hit ENTER and bash (#) comes up? You shouldn't need to wait 10 minutes. Heck, I don't even think a minute passed between running !EXEC and being able to enter !CTRL POFF.

!CTRL POFF will not do anything at all. It simply tells the phone to power off once the cable is unplugged from the phone. After it powers down, are you remembering to hold VOL DOWN and POWER. Then when the LG V30 image shows up, quickly release POWER while continuing to hold down VOL DOWN, and then holding down POWER again. You can't let too much time pass between releasing POWER and pressing and holding it again. I want to say release, then immediately hold it down again.
[LG V30 Guides, News, & Discussion] maddangerous:
Hmm... after entering the first command, then next prompt comes up basically instantly for me, if that matters.

I'm gonna try this on a different computer from my primary rig when I'm back from lunch.
[LG V30 Guides, News, & Discussion] [Cruzer]:
correct it shouldn't matter.. just wanted to verify that its seeing twrp.img file. As this shouldn't be rocket science ( since now we don't have to worry about unplugging at the right moment ). but no matter what I do. Can't get TWRP installed. But boy am I and expert at Factory resetting my phone to 10d. :silly:

EDIT: i'm going to change my avatar to a Rainbow Circle and below will say "Erasing".
[LG V30 Guides, News, & Discussion] SweetwaterBurns:
For those of you that that are having issues with flashing twrp, when/if you repartition the card are you making sure that it is the first or only partition? If you have another partition on the card only the first will be mounted in externalsd
[LG V30 Guides, News, & Discussion] Cj719:
Do you think you will find a way to get download mode back for k20 besides waiting for OTA?
[LG V30 Guides, News, & Discussion] [Cruzer]:
Since Brian said we can use Fat32 now.. I went ahead and re-partitioned the drive. Using the entire microsd card. Still no go for me.

[LG V30 Guides, News, & Discussion] SweetwaterBurns:
How big is your SD? I made a single 2gb fat32 partition and it worked. Maybe there's a size limitation?
[LG V30 Guides, News, & Discussion] [Cruzer]:
smallest I have is 32gb.. but will try, diskpart, repartition with fat32 and 2gb part size.

EDIT: nope nada
[LG V30 Guides, News, & Discussion] runningnak3d:
In the little text area at the bottom of the download mode screen, does it say in red: "Failed to mount SD card" or "SD mount error"? If you aren't getting an error on the phone, then it is mounting your SD card, and you are having some other issue.

Thanks for the hard work and the detailed tutorial, success! :cool:
[LG V30 Guides, News, & Discussion] [Cruzer]:
Nope, says "633A 897"

"Official / E / L / RO"

guess I have to keep trying.. but just to be clear.. since there is not progress bar of any sort.. about how long should we wait after running !EXEC 1 to 2min? less or more?? Thanks :)
[LG V30 Guides, News, & Discussion] Josh McGrath:
The progress bar doesn't move until the poff command and then it just flashes to 100 pct.

The EXEC command should literally take about 1 second and pop up with another # on the next line
[LG V30 Guides, News, & Discussion] phoneyDev:
I think this command:

!EXEC toybox dd if=/storage/external_SD/twrp.img of=/dev/block/sde bs=4096 skip=10246\0

Should be this:

!EXEC toybox dd if=/storage/external_SD/twrp.img of=/dev/block/sde bs=4096 seek=10246\0

"seek" not "skip"

It worked for me.
[LG V30 Guides, News, & Discussion] [Cruzer]:
OMG i'm going to kiss you.. that did it for me....
[LG V30 Guides, News, & Discussion] maddangerous:
Alright, I went through the process on a different computer.I Have the phone and FWUL flash drive plugged directly into a USB root hub in the back of the machine. Used LG provided cable. I reformatted the SD card for magisk/twrp, FAT32, 2048 MB, did a normal (not quick) format this time so that it would mark bad sectors not to be used (bit of an older SD card).

Still no dice. Really not sure why. I don't have SD card mount errors

I would try this if I was more familiar with DD, I'm pretty alright with linux in general, but I've never touched DD so... not sure what exactly that does. the DD MAN page "explained" it, but, I don't know what it actually does lol

[LG V30 Guides, News, & Discussion] ewatt99:
That fixed it, I got twrp. It asks for a password though, I remember seeing this mentioned so ill look around the forum or someone can just rely with an answer.

Edit: Also, do we use the same method initially to get into twrp every time? or is there an easier way that isnt risk of removing it. Thanks :)
[LG V30 Guides, News, & Discussion] runningnak3d:
While in stock recovery you should be able to adb sideload update.zip

-- Brian
[LG V30 Guides, News, & Discussion] runningnak3d:
Click cancel, then format data, then reboot back into recovery. When you click reboot, there is a button for recovery, that will boot you right back into recovery.

This time it shouldn't prompt for a password. If it doesn't, then flash Magisk.

Once you flash Magisk, it will take care of everything so you can safely boot into the OS. From there, you can download any of a number of "boot to recovery" apps from the play store.

I'm still in 10d. If I go thru the process and have root, is it possible for me to relock bootloader and unroot? I use Citrix Secure Mail for work, the app might detect unlocked bootloader and root.

Ok managed to flask all kids files and lad but when I try to boot into twrp it shows a warning screen and the phone just shuts off the warning comes after the white screen where you press yes twice
[LG V30 Guides, News, & Discussion] mattgyver:
It's called Magisk Hide. It's part of the Magisk Manager. This brings up a good point to make. If you upgrade to Oreo, and root, Magisk Manager 6.0.0 will crash when you try to open Hide. You need to revert to v5.8.1. It will ask if you want to download/install 5.8.2. Say yes. DON'T update to 6. 5.8.2 works with Hide. V30-Oreo-Magisk v16-17.1 combination is causing the crash from what I've been reading online..

BUT it's a toss-up. Do you want hide, or SafetyNet passing? 5.8.2 gives a "response is invalid" when checking SafetyNet status.....
[LG V30 Guides, News, & Discussion] el.quechon:
For anybody trying to root make sure you download adb and unlock the bootloader if you won't boot twrp
[LG V30 Guides, News, & Discussion] mattgyver:
An unlocked bootloader is the very first requirement. It's the first bullet point in the very first section of the OP titled WARNING.
[LG V30 Guides, News, & Discussion] zrzhu:
I think Citrix Secure Mail may check both root and safetyNet. If it does, can I relock bootloader and unroot or install a rom with no root?
[LG V30 Guides, News, & Discussion] BrandonB1218:
Yes, you can relock the bootloader, and yes, you can unroot. Currently as far as I'm aware there are no ROMs that are working on the H932, besides the Oreo ROM runningnak3d provided.
[LG V30 Guides, News, & Discussion] el.quechon:

How do I fix this? This now happens when I open LGUP while my phone is connected. USB debugging is enabled and all drivers are downloaded.
[LG V30 Guides, News, & Discussion] lowkeyst4tus:
Been there.. 2 things to get you through the process is to make sure you use factory cable.. broken files appear complete.. second after installing twrp, don't boot normally.. boot to twrp via button combo.. after updating to Oreo ( where I broke files, factory cable) flash magisk.. might reboot at LG logo once or twice on 1st boot.. 1st boot might take awhile.. just wait.. I recommend doing a twrp backup after booting rooted Oreo..

I feel like you should know this by now, but... The first post has a 10d KDZ link right in it. And not too long ago in here, somebody posted the link to the thread that has the rest of the T-Mobile KDZ firmware files (including the 10k KDZ). Just grab one of those and install.
