Please help!
My phone now stuck at the fastboot
It shows PRODUCT_Name - LM-V4059N and when I tried to boot the rom, the yellow triangle appears.
I flashed in slot a, at fastboot it shows slot a active too. I'm already flashed back to Pie abl and it stucks at fastboot, 1 more thing, when i use the code flash oem unlock the second time, cmd shows FAILED (remote: unknow command)It sounds like your device switched slots? Or maybe you flashed to both slots and are trying to boot the phone with the eng abl flashed?
It's important to realize, as the guide says, the eng abl is Oreo. It will not boot any other OS but Oreo. It's only to be used to unlock the BL and then flash the original abl back, so the phone can boot.
cheers

My model is Korea KT V409N, sorry for my typing mistake sirsounds like kind of a mess. Which model is your phone originally? Vzw? att? Kor?
So if yer flashed back to original pie abl... how do u still have fastboot? are you getting to the fastboot screen using pwr+vol up? You're getting to fastboot just by booting phone?
and, the command to unlock bootloader isn't 'fastboot flash ...' it's just 'fastboot oem unlock'. The command 'flash' is for flashing a partition. The 'oem unlock' doesn't flash anything.
cheers

I'm already flash back to pie by kdz and the bootloader was unlocked but I can't access to fastboot by cmd nor button.
Gosh, this phone so hard to install twrp
Any solution for this? Thanks, have a great day.
Could you give me the file of 409N 30f?stock 10? att? sprint? vzw? korean? And stock 10 what? 10c? 10d? 10e?
sure this is it.
So sorry, I'm a bit nervous. Replace this file here, right?sure this is it.
remember, flash this with qfil or fastboot to the current boot slot. After flashing, go immediately to recovery, don't boot phone.
1) if it asks for password just cancel
2) format (not wipe) data
3) reboot recovery
4) flash magisk
5) flash dmverity
should be all set then.
I'm sorry, but I stuck in Fastboot, even after flashing boot_a, then reboot to recovery mode, then factory reset. It cannot boot into twrp.sure this is it.

Ah, after all, I can go into TWRP by flashing boot_b and reboot recovery. Thanks a lot!!!!!sure this is it.

My phone is LM-V405UA software version V405UAg. I followed the steps and bootloader shows unlocked but I can't flash TWRP. My error is 'Cannot flash this partition in unlocked state' Of all the steps, I missed "fastboot flash frp path/to/frp" but went straight to "fastboot oem unlock" and it did unlock it, shows it in fastboot. I also couldn't "fastboot flash abl_a path/to/ablpiestock.img" so flashed it via QFIL -> abl_a. Would someone know what could possibly be the issue? I've gone back and forth between reflashing V35engineering, deleting laf_a and laf_b, rewriting them (thanks to someone who provided them here) etc. but nothing works. My goal is LineageOS. Many thanks!
Thank-you much for helping out!And lastly, your software version is something like Korean Open 30f, or maybe US OPEN 20e, or maybe AT&T 30d, etc etc. You have to know the exact info for anyone to be able to help.
How do I do this?Depending on the version of Android, the newer ones, which you *probably* have, you don't flash twrp anymore, you have to have your specific boot partition with twrp injected into it (then you flash that specific boot partition).
Thank-you much for helping out!
I don't know, software version says V405U20g and it starts with a splashing Sprint sign... Kernel 4.9.112. The phone I bought "new" off ebay.
How do I do this?
Any ideas why my phone refuses to show up under the Qualcomm HS-USB QDLoader 9008 port? I can only get it listed as LGE AndroidNet USB Serial Port. I believe the bootloader is currently unlocked but I'm feeling like I'm missing something on my pc for the connection. I've attempted to follow the resolutions in this thread but no luck so far. Obviously doesnt show up under the QFIL port menu, it does appear when the "Show Non QDLoader\DIAG Port" checkbox is selected, but still under the LGE AndroidNet USB Serial Port name.
Realize I should have included this information:
Model: LM-V405UA
Android Version: 9
Kernel Version: 4.9.112
Downloaded latest version of QPST (latest I found was 2.7.480) and I also have the LG Mobile Driver WHQL version 4.2.0.

fastboot oem unlock
fastboot flash abl_a path/to/ablpiestock.img
fastboot flash frp path/to/frp
fastboot oem unlock
Awesome! You guys are brilliant!
So do we expect a kickstart in development (like the V30's dev scene) now that an unlock is available for everybody?
And one last question: does this mean that we can unlock a (network) locked phone this way? I know that the usual answer is 'no', but from what I've seen around here, there's something called 'cross-flashing' of US unlocked firmware. Perhaps that means an unlock?
If not, do online unlock services work? (I do not want any names - I just want to know whether any service at all works).
I do apologize if my questions are stupid - it's only that with the overwhelming amount of (sometimes contradictory) posts here, I just want to make sure I'm doing everything correctly! :laugh:
