Sorry for the long wait. I did not see this response.

From where are you trying to mount system? TWRP or within the OS?

I have no idea about dual booting. Did you try to defeat forced encryption as described in this thread <https://xdaforums.com/lg-v40/how-to/guide-twrp-data-access-stock-t3970149>?

I picked up a v40 on Oreo and unlocked the bootloader with this method and screwed something up. I want to enter download mode but it just enters download mode for like 5 seconds then reboots . I booked my laf partitions and also flashed ablpie which I know now I shouldn't have because I'm on Oreo . Everything works fine I just can't enter download mode to update my phone using lgup. Anyone have a quick remedy for this? I think if I can extract the correct abl and laf images for my current fw icsn flash them back. Just a thought . Any ideas I'm all ears

Can you switch slots via Fastboot? Will Download Mode work on the other slot?

[NG]Owner
[LG V40 Guides, News, & Discussion] herb9876:
Yes I can switch slots and I have . I can boot Into 9008 mode and use that fully . I can pretty much do anything except the one thing I really need to do and that boot into download mode. I've tried everything even dumb things out of frustration. In the end I just need to basically unbrick. I think there must be a way to get download mode back but the only laf images I could find for v40 don't help . Reflashed both laf_a and laf_b a million times with laf.img I found inside the zip of the post regarding crossflashing with or without root.

Something is telling me I shouldn't have booked the laf partitions and I know I shouldn't have flashed ablpie after unlocked the bootloader due to the fact this phone is on 8.1 .

There are a couple posts around with the same issue as I'm having but none ever were solved or responded to. Red triangle green screen download mode only for 5 seconds then reboot etc etc. The lg g7 has a thread about how to use 9008 mode to fully unbrick using raw files along with the firehose file which is exactly what I need . I know at&t doesn't release kdz and the only abl I can find is of the pie version. I even tried gsi system images which won't boot. If you know how to get the other files required to unbrick to put with the already provided 845 firehose file id be in business. Any ideas greatly appreciated thanks

The only thing I can think of is this. Download the US Oreo KDZ and then research a way to get the laf_a and laf_b binaries out of the KDZ. Then flash them via 9008. Other than that, I'm stumped. Sorry.

ok i got my phone back. i went on craigslist and someone had a UA us cellular lg v40 for sale . it looked like it was run over by the space shuttle but it turned on and was functional. it was on the march 2020 pie fw. i just put it into 9008 mode and literally one by one backed up every single partition (i think there are 95) . Then i put my borked v40 which was on oreo into 9008 mode and one by fking one flashed all 95 partitions including the 40gb userdata partition. then took a deep breathe uttered a couple words and held power and volume down. it booted right up needed to reset the data and rebooted again and im good now. i am in the process of uploading the 94 partitions to mega ill put the link here in a few hours in case anyone needs to do what i did . im sure there is an easier way to do this but i had no download mode and no clue. need a nap

[LG V40 Guides, News, & Discussion] zfk110:
Did you enable oem/ USB debugging and remove any passwords earlier to follow the guide? Also post pictures.
[LG V40 Guides, News, & Discussion] NGOwner:
Well you start over. Boot the phone into download mode, and load up the US KDZ (assuming you're in the US). Go through enough of the setup of Pie (I'm assuming you want Pie) to get to developer options and enable OEM unlock and ADB/USB debugging. Then reload the v35 engineering bootloader, and proceed.

As long as you have download mode, you can always start over and try again.

[LG V40 Guides, News, & Discussion] zfk110:
deto to step 4a. Reboot right back into fastboot (hold volume down after rebooting) and run: fastboot oem unlock

I didn't nuke my lafs

Then I tried to fastboot boot TWRP-judypn-boot.img while still in fast boot.

It bootup the phone and then it will stuck into LG logo screen, nothing else happens, I have to force restart the phone.

When I try to go back to fastboot it's not there anymore, I can only go into download mode. Still, no sign of TWRP. I got ATT convert into Unlock US running with Pie.
[LG V40 Guides, News, & Discussion] Buzzy42:
I'm having the same issues on the V405QA unlocked. Somehow I got it to work ok, starting with a stock 20e install, but after I got it all installed, the phone somehow reverted itself to 20a. So I decided to use LGUP and flash the 20e KDZ and now I am having the same problems you describe-- I can get the phone re-unlocked, but I couldn't get TWRP to boot from fastboot (Same problem you described, LG logo stuck) and now I can't even get back into the bootloader at all no matter what I try. I've tried to re-flash just the abl_a partition from the KDZ and nothing.

I should've just been happy with 20a and rooted, I guess! I read someone in another thread indicating that TWRP might not be compatible with 20e, has that been confirmed?
[LG V40 Guides, News, & Discussion] whitedavidp:
I have the same model exactly. When I started all this the phone (which came with 20a) had auto-updated to 20e. I think that update was part of the difficulty I had. Since this is a dual slot phone, the update went onto the B slot (since the 20a it came out of the box with was factory installed onto A). What I did after much consult here and in other threads (thanks for all) was get the phone into download mode and flash the 20e using LGUP. I had to be careful and not use refurb mode. I was told to use partition download and de-select some of the partitions to prevent them being clobbered damaging the work I had already done. It turns out that flashing with LGUP leaves you in the A slot with the new firmware. If you look around in either this thread or the TWRP thread you will find my posts.
[LG V40 Guides, News, & Discussion] Buzzy42:
Awesome, thank you so much for the tips -- I think the dual slot thing messed me up too at various points (I'm curious if perhaps I didn't really 'revert' to 20a but I got switched to the other slot and didn't realize it). Did you ever have to revert back to 20a or were you able to just move forward with 20e? (I'm thinking I might try to replicate my near success and go back to the 20a KDZ, then let it upgrade to 20e,but then work on the b-slot bootloader/etc for rooting/flashing TWRP)

It's good to know that there IS a path to 20e + bootloader unlock + TWRP + root..! :D
[LG V40 Guides, News, & Discussion] Buzzy42:
Just to follow up, I was able to get it fully rooted and unlocked on 20e! Thanks again for documenting what you did, I mostly had to follow what you posted at https://xdaforums.com/showpost.php?p=82206107&postcount=115 (with a few tweaks for my specific situation, where I managed to get my phone in even worse shape than yours and had to do a full restore using the 20e KDZ, nuke the laf_a partition, and installed TWRP twice on both boot partitions to really finally get it to 'stick' for some reason... lots of rebooting back into recovery!)

Now I can finally set up my V40!

Would be nice if you provide details about varuan6, software version, what you did exactly and more
[LG V40 Guides, News, & Discussion] ultoramansaga:
Well first of all I followed everything but after unlocking the oem I was stuck in the fastboot mode I thought it was something related to the download mode, so then I nuked the laf. After that point I was only getting a black screen with a text at the top saying press any button to shutdown, after pressing every combonation I could search for nothing seems to work. That's when the phone just got stuck inside the qualcomm 9008 mode which I cannot get out off. Being stuck on qualcomm 9008, I thought I could reinstall firmware by using QFIL and tried to follow instructions online. The instructions online didn't really helped much at all. Also, when I checked the partition manager it was empty like nothing.

The software version I'm using is LMV405EBW HK region

Edit: I think the reason why the partition manager was empty is because due to nuking the laf
[LG V40 Guides, News, & Discussion] Redacted Kaos:
OK so I have one of the phones with no bootloader so do I need to nuke the LaF in the beginning when I am first entering the partition manager? Nuke the laf and then flash the V35 correct?

[LG V40 Guides, News, & Discussion] NGOwner:
Start over. Use downoad mode to reload the appropriate KDZ. Go through enough of the Android setup to get to developer options, and enable ADB and OEM unlock. Then follow the directions to unlock the bootloader. Then the directions to install TWRP and root.

There is no comprehensive guide from start to finish on this device. You have to bounce back and forth between multiple forum threads to get a new KDZ, then the bootloader unlocked, then TWRP with data access and root. If something goes sideways, restart with a reload of the KDZ.

Nuking laf is only important if you want to retain fastboot (at the expense of download mode) after you're done. If you have already nuked your laf partitions, you'll need to find a way to extract them from the KDZ, and flash them using 9008 to get started again. Good luck!

So here is a link with the laf_a and laf_b binaries I extracted from my 20e Pie load.

I would think if you uploaded these individually to their respective locations through 9008, you would get download mode again so you would be able to load whatever KDZ you needed.

V40 405ebw with pie firmware

Hi EVERYBODY,

I have a LG V40 EBW with australian pie firmware and i tried to follow these instructions and got as far as sorting my boot loader BUT was unable to go any further :( as my original rom is a PIE rom and unfortunately the guy who did this post only mentioned later that it has to be oreo to follow this guide :(

Would anybody have a link to an australian oreo firmware for this device?

Is there a method to get this phone sorted straight from pie?

I have been working on it for two days now and im going a bit nuts trying to figure it all out.
[LG V40 Guides, News, & Discussion] NGOwner:
You can get this phone sorted straight from Pie. I think you are misreading the directions.

Use the v35Engineering bootloader to enable access to fastboot commands.

Once you are done with all steps involving the v35Engineering bootloader and all steps involving fastboot commands, you need to flash the ablpiestock.img to enable booting back to your Pie OS.

Once you have flashed ablpiestock.img, you immediately lose the ability to access fastboot commands (assuming you haven't nuked laf_a and laf_b). So make sure you are done with fastboot before flashing ablpiestock.img. Note that fastboot commands are not adb commands. You will still be able to use adb commands after flashing ablpiestock.img as long as you toggled adb debugging on from within developer options.

I'm trying to get into my V35's partitions using the firehose file and QFIL version provided on this thread. Since they are both running SD845, I was told that the steps here would work.

However, despite trying:

2 Different PCs

3 Different USB cables

7 Different USB Ports across 2 PCs

I can't seem to get into the partition table using QFIL

I'm able to select a Qualcomm 9008 port on QFIL which means that EDL mode should be active. Its just that QFIL can't seem to open the partition table so I can begin reading items from it or flashing images to it.

Any clues or ideas?
[LG V40 Guides, News, & Discussion] whitedavidp:
What reason do you believe the file is usable on a V35? I am no expert but I was under the impression it was only for V40. It is true that this process uses a V35 boot loader temporarily to unlock the boot loader on V40. But I am not at all sure that one can expect more.
[LG V40 Guides, News, & Discussion] digitalsonic:
That is pretty much what I'm trying to accomplish at this point - unlock the bootloader. At least until the portion wherein QFIL connects to the device in EDL mode, there should be no difference between a V35 and a V40. So I thought to ask here in case someone can figure out what I missed/am missing.

There are mentions of people using the same process to unlock their bootloader for the G7/V35s I believe, and the guide I was following pretty much redirects me here for the firehose file.

I see. Thanks. All I can say is that maybe you have a corrupt firehose file? I used the one linked here, not the one linked on the thread you mention. But made sure I selected flat and it just worked for me on my V40. Maybe try re-downloading? Good luck.

Can you get into download mode and re-flash an entire .KDZ? I found that after doing all this and nuking at least one LAF, I have to switch to slot B and reboot and then hold VOL UP + USB. Did you managed to install TWRP? If so, you can switch slots there. If not, I would try to re-install the V35 engineering boot loader and you should be able to use Fastboot there to do the switch.
