So, let me see if my detective work has helped... you just joined today, and have 2 posts. The one above, and another indicating your device is a G7 and not a V40?

You pop in here, indicating you flashed ablstockpie.img, but it didn't work. Which stock pie image did u flash? The one in this thread for the V40? If so, that's why it's not booting, it's not for your phone.

And you say "after hours stuck in fastboot" u finally managed to flash abl_a etc etc. That's one of the oddest things I've ever read on xda. It took you hours to type in 'fastboot flash abl_a ablstockpie.img'? That's one slow keyboard ;)

With such little information to go by, the only other guess I have is that you did flash the verizon pie abl_a for your G7, but are you on Pie? If you're on 8, you have to use it, etc etc, the versions have to match, as does the device.

good luck

red triangle and fastboot loop

Hello, I need urgent help I have a Sprint v40 with Android 10 croosflash and I did the v35 loader procedure with qfil. But now my LG v40 is on the red symbol (the triangle) and it just goes up to the fastboot and says in devices state: lock

Pdt: I am new it is my first time commenting and doing these procedures. I know you guys are smart :)
[LG V40 Guides, News, & Discussion] AsItLies:
So, your device was originally a Sprint device right? You crossflashed it to A10 right? Which A10? Which rom is running now?

The V35 engineering abl is Android 8 (Oreo) (your device won't boot if it's running anything but Oreo - with that abl), just as you're experiencing. The point of flashing it (on any OS version) is to then unlock the bootloader and **then** flash back the original abl, so the device will boot.

It says all of this in the original post. If you're on anything but Oreo, it's not going to boot. You flash the v35 abl, you go **directly** to fastboot after flashing, u unlock, u flash back original abl (in fastboot), then it will reboot as it should (albeit with an unlocked bootloader).

good luck.

Unlock bootloader

Thank you, I really thought that no one was going to answer me. I already have the bootloader unlocked and now I only need the boot.img that I don't know how to get it out, someone to help me how to get the boot.img ... I have Android 10 I did a croosflash and download the jordan version this is: https: //lg-firmwares.com/es/downloads-file/22707/V409NO30b_00_OPEN_KR_OP_0515
[LG V40 Guides, News, & Discussion] AsItLies:
You can get any of the images (partitions) easily by using qfil (EDL mode). It's the same thing used to flash the v35 eng abl. If you want the boot image to flash with magisk, crossflash the device (you already have done that), then get to edl / qfil mode and use partition manager to 'retrieve' whichever partition you want.

it's very easy actually.
[LG V40 Guides, News, & Discussion] El_franco2:
Is it really that easy !? Can you guide me a bit please T.T I don't know much why I'm a newbie in this (it's my first time doing all this) even though I always watch videos of this. I really thank you very much if you help me. :)

Pdt:I don't have download mode

Edit: now I did what you told me but now when I give it to read partition it gives me an error that says: read data fail firehouse. :/ Help
[LG V40 Guides, News, & Discussion] AsItLies:
I'd suggest going back to the original post and re-reading it a number of times. The laf partition, as it says, is basically what controls having 'download' mode or not. If you erased those partitions (to get fastboot mode), then you will have to flash the original laf back on so you will have download.

I can't do a better job than what's already been done re writing the directions. Re-read them a few times and it should be clear, eventually.

good luck

Almost! only abl_a and download mode

aaah I understand! abl is what allows you to boot the phone, why when you install the v35eng it installs it in abl_a and the phone boots in v35 engineering mode and for the phone to boot again you need to restore the original abl_a (the factory one) that's why is that you have to make a backup copy of all these partitions. If someone helps me to get this partition (the abl_a) I would appreciate it very much and in return I will make a post about the whole process that I went through doing this for the first time. I will also pass my boot_a.img and b (I am on Android 10 Korea version I did a croosflash) and if we all share our errors and solutions, we will be able to help most of the people who are doing this. If you help me get the abl_a of Android 10 kdz korea, I will make a post with the problems and solutions;) here my data: LG V40 Sprint with croosflash of Android 10 Korea version ... This: https: // lg- firmwares.com/es/downloads-file/22707/V409NO30b_00_OPEN_KR_OP_0515. I have the bootloader unlocked and I do not have the download mode (I do not have the laf: / partitions) Really if you help me with that I will make that post with the solutions I made for the failure of qsahara fail blablabla ... any recommendation or the abl_a of a person who has this same version would be of great help, not only to me ... but to all those who read the post and have the same problem. ATT: El_franco2

PDT: I thought that flashing the boot.img solves it ... But no, what I need is the abl_a and the laf partitions.
[LG V40 Guides, News, & Discussion] AsItLies:
You can try these, not sure if they will work as they are from 30d not 30b. good luck.
[LG V40 Guides, News, & Discussion] El_franco2:
THANKS! finally ... I was able to start my phone. The abl_a didn't work for me but the laf_a worked for me so I'm going to write the post that I told you about. Finally a question :) do you think twrp works for me on Android 10? I try to see? What do you say!? THANK YOU crack !!
[LG V40 Guides, News, & Discussion] AsItLies:
Good. Yes twrp is working on 10. Look in the V40 Roms Kernels recoveries forum. There are quite a few threads about it in there.

cheers
[LG V40 Guides, News, & Discussion] El_franco2:
I don't know what to wear!

Thanks again! What do you say if I make the post I talk so much about !? Talking about my mistakes etc ... Will it help or is it not that important? Pdt: already remove the partitions from Android 10 (30b)
[LG V40 Guides, News, & Discussion] AsItLies:
Well, that's up to you, of course. But I'd say that if it's not a matter of correcting any errors? It might just add to the confusion?

No recovery option

Finally nuked laf and now got into V35. But, how do i go to recovery? It only gives restart and power off
[LG V40 Guides, News, & Discussion] AsItLies:
For those that have trouble getting into EDL mode (which is all of us I'd bet);

Just read a comment on Tele group indicating a fastboot command that works. So just tested it with fastboot made available from nuke laf partition (no download mode now (until laf falshed back), so plug usb with vol+), and sure enough, entering 'fastboot oem edl' will put the phone in edl mode.

Dang that other way pressing vol+ as fast as you can and having it reboot over and over was so frustrating ...

cheers

---------- Post added at 10:22 ---------- Previous post was at 10:15 ----------

usb and vol+ 'normally' puts mode in 'download' mode (for LGUP to work). But if you nuked the laf, it won't do that anymore, because laf is the partition need for LGUP to work. So why would you want to nuke laf? because if you nuke it, then use those keys to get to it, it will go to fastboot mode instead.

The reason you nuke laf (for fastboot) is because the V35 engineering abl is for OREO ONLY. In other words, if your OS is ANYTHING BUT OREO then it won't boot with the v35 eng abl. (That's why you use it to just unlock bootloader, flash the original back, then nuke laf to have fastboot instead of LGUP - flash laf back if you need LGUP).

This is, again, in the original directions. TAKE THE TIME TO READ THEM CAREFULLY!!! Honestly, if you can't follow them, after putting in some effort... maybe this isn't for you?

something to think about.

---------- Post added at 10:28 ---------- Previous post was at 10:22 ----------

And a simple google search answers how to get to recovery with lg devices:

How To Enter Recovery Mode On LG V40 ThinQ

Turn off the device.

Press and hold Volume Up + Power buttons simultaneously till the device logo appears.

When it logo appears, release Power button but hold the others few more seconds.

Release all the buttons when Recovery Mode screen appears.

Hello, I have LM-V350ULM which had G710ULM21f_00_NAO_US_OP_0219.kdz (Pie) firmware when I received it. I flashed G710ULM11g_01_NAO_US_OP_1112.kdz (Oreo) following this guide https://xdaforums.com/lg-g7-thinq/how-to/howto-ulm-bootloader-unlock-root-20e-t4068885. I installed the drivers properly and got into EDL mode (shows nothing on screen and shows Qualcom 9008 in Device manager), the QFIL part went smoothly too but it did give me an error saying "please choose the correct programmer" when I opened the partion manager but clicking OK opened it anyway (it showed "File sent" after I loaded abl_a with v35eng file) then I went in fastboot mode (which shows "ACTIVE A/B Slot - _a") and proceeded to put "fastboot oem unlock" command in cmd I'm getting the error "FAILED (Write to device failed (Too many links)) fastboot error: Command failed". I've tried different USB ports (both 2.0 and 3.0), different cables, different command: "fastboot flashing unlock" but to no avail I keep getting the same error. Please let me know where I've went wrong, thank you.
[LG V40 Guides, News, & Discussion] AsItLies:
I've not used any of the firmware you've mentioned... but, a couple of common things; 1) have you gone into developer options and 'enabled' oem unlock? 2) my experience is when unlocking (or trying to relock), it's best for the device to be completely stock, no modifications, for locking, don't even select 'language' when it boots, just shut if off ans use fastboot.

When unlocking, you're going to loose all your data anyway. So set it to factory, go through the settings and skip all that you can, and only enable oem unlock. **IF** your developer options doesn't have the ability, there's an FTM partition one needs to flash to overcome that.

If you've already done all of the above, only thing I can think is, like you've been trying, diff cables, diff ports, possibly even diff computer.

good luck
[LG V40 Guides, News, & Discussion] pipboy.jaxx:
Yes, I had enabled OEM unlocking and Debugging options in Developer mode. Losing data isn't an issue I've backed up everything I needed. It seems the phone just doesnt accept any kind of fastboot commands, when any type of fastboot command is put the phone goes to logo screen with "Press any key to shutdown" on top right corner.
[LG V40 Guides, News, & Discussion] AsItLies:
so, don't remember, you're using the engineering abl right? You're not trying to do this with a deleted laf partition?

Assuming you are using the engineering v35 abl, then it **has** to be an issue with your firmware, that they somehow are not allowing the unlock. I've no idea what to do with that, sorry.

I mean, if fastboot devices see's the device, then you have a good connection, it's working, in that regard anyway.
[LG V40 Guides, News, & Discussion] pipboy.jaxx:
Fastboot devices does see the device and the file was named v35eng.img or something like that ... also I didnt delete any partitions... I think I'll just pop back to a pie firmware and forget about this ...it's too annoying of a process

[LG V40 Guides, News, & Discussion] AsItLies:
so, you managed to unlock the bootloader? Which slot did you flash the engineering abl to? That's what gave you fastboot->that then allowed u to do 'oem unlock'... did u flash the oem abl back? Because the phone won't boot if u keep the eng abl on there.

and 'adb reboot bootloader' isn't going to work because the eng abl shouldn't be there. Is this making sense? I'd suggest to say 'exactly' what you did, i.e. how u got the BL unlocked, and what u did afterwards. Maybe then people can help.
