V40 has unlocked bootloader and can fastboot, but is otherwise bricked. Any hope for TWRP? - LG V40 Questions & Answers

Having trouble installing TWRP.
I can fastboot and attempt:
`fastboot boot TWRP.img`
But it either fails or "succeeds" and then just hangs on the LG Logo.
`fastboot flash recovery TWRP.img`
-returns an error that recovery_a doesn't exist.
`fastboot flash abl_a TWRP.img`
-returns "Volume is Full"
Any ideas what I may be doing wrong?
Device is an ATT LG V40 with the V35 Engineering Bootloader if that helps.

You don't say if it's at&t pie or Q. Let's assume it's Q 30b?
Follow this link for the bootable partition with twrp already injected. You can either use qfil to flash it, or more easily since u have fastboot, just do fastboot flash boot_a the_name_of_the_file.img.
The only thing about using fastboot is you want to save the original boot_a image first. At&t doesn't make their kdz available and if u want /need to go back to stock u need to save it first.
After flashing it (either way), you need to immediately go to recovery, don't boot the device, u have to format data and reboot to recovery and then flash magisk and no verity zip. Otherwise a backup of your data won't work as it will be encrypted.
just one point, don't every flash something to a partition when yer not sure what yer doing. The abl partition is only about 1 meg in size, it's the 'android boot loader'. You could, if unlucky, flash something wrong for that partition and end up overwriting the partitions that are next to it, and essentially (just about) brick the device.

This gives me the following:
Writing 'abl_a' FAILED (remote: 'Errorflashing partition :Volume Full')
I receive a similar message for `abl_b`, `recovery`, and `boot_a`
If I attempt flashboot boot the_image.img then I can get a success message on the fastboot-side and the phone reboots, but once again just to stick at the LG V40 screen.

Wow, so I don't think you understood some things. First, stop trying to flash an image to the wrong partition then what it's for. It is NOT for abl_a, and it is NOT for recovery (there is no recovery partition on a treble phone). STOP DOING THAT.
and second, because that boot_a (ONLY!!!) partition is for Q, as I said, you need one for Pie, and shouldn't even be trying to use it anyway.
and third, you can't fastboot boot these boot/twrp images, they have to be flashed to the partition and then you have to boot to recovery immediately after (don't try to boot the phone).
So if you can't flash the image with fastboot then the only option would be to use qfil, again, be sure to back up the original image first.
I'll look around and see if I can find one for Pie. We may have to create one if it's not around.
cheers

Just checking, but u do know how to use qfil yes? And, how did u get fastboot on the device? Using qfil I'm guessing? and you deleted laf_a? or the engineering abl?
This info is important because 1) the fastboot you get when simply erasing the laf_a is not as powerful and full featured as the engineering abl. The actual capabilities of the (laf_a erased) fastboot varies by OS variant, but some of them are basically worthless.
2) you'll have to be able to use qfil to get this accomplished.
let me know and we'll go from there.

[Q] Cannot flash recovery (TWRP)

I just got a Moto X on Sprint, and after successfully unlocking the bootloader, I do not seem to be able to flash TWRP. The flash seems to go ok, but when I boot the device into recovery, its still the stock recovery. Im attempting to use the official openrecovery-twrp-2.7.1.1-ghost.img image. Ive tried using the standard fastboot on OSX and WIn7-64bit, and in both situations I get this output:
Code:
fastboot flash recovery openrecovery-twrp-2.7.1.1-ghost.img
(bootloader) Variable not supported!
target reported max download size of 805306368 bytes
sending 'recovery' (8220 KB)...
OKAY [ 0.749s]
writing 'recovery'...
OKAY [ 0.879s]
finished. total time: 1.629s
The variable not supported seems to be the 'getvar partition-type:recovery' command (based on the output on the phone).
I have also tried using the fastboot provided by Motorola with the same output and result. On the forums somewhere I found a link to an older moto-fastboot-osx command, which has slightly different output, but the same results:
Code:
moto-fastboot-osx64 flash recovery openrecovery-twrp-2.7.1.1-ghost.img
sending 'recovery' (8220 KB)... OKAY [ 0.787s]
writing 'recovery'... OKAY [ 0.909s]
What am I doing wrong?
Have you double checked that your oprnrecovery-twrp...img file is not corrupt? Make sure to check it against the md5 checksum.
Yes, I verified the MD5, it is correct.

Just a few thoughts...forgive me if any of this sounds redundant, or obvious....
Just reading your initial post, I would assume that you had used one of the previous root exploits and/or Safestrap BEFORE you got the BL unlocked. If so, it would be necessary to flash the entire stock SBF, before you would be able to successfully flash TWRP recovery........but your OP says you JUST got the phone, which would lead me to believe you didn't use a previous root exploit. Did you receive it NEW? Because the original owner could certainly have used exploit/safestrap.
If any of this is possible, you should follow the "Return to Stock" thread (manual method is suggested - easier and faster) and flash the entire Sprint 4.4.2 SBF. THEN you should be able to successfully flash TWRP. As I have often stated, a full SBF to stock can actually REPAIR a corrupted / modified (exploit / safestrap) filesystem. A "Factory Reset" does not repair any corruption that may be present.
2nd thought: I've seen some people confuse the "bootloader" screen (AP Fastboot Mode) for recovery. From the bootloader screen, you have to arrow down to highlight recovery, and press volume up to boot into recovery.
Alternatively, you can do it from fastboot: just type fastboot reboot-recovery
Let us know if any of this is relevant or solves your issue. If everything else fails, doing a full SBF back to stock fixes all issues nearly 100% of the time.
Good Luck

It was purchased used, and the original owner was not very tech savy, so I assumed it was fully stock (it appeared so at first glance, anyway).

Haha, yes, I was hesitant to suggest there may be confusion between bootloader and recovery.... Glad you were on top of that one...
The return to stock thread is located here: http://forum.xda-developers.com/moto-x/general/guide-moto-x-return-to-100-stock-using-t2446515
Again, manual method is easier and faster.
You will flash the 4.4.2 Sprint SBF file from here: http://sbf.droid-developers.org/phone.php?device=0
If my first theory was correct, you wouldn't be the first person who received a used phone that had an exploit used on it. The devs make it pretty easy even for not-so-tech-savvy people with all the "one-click" rooting scripts and the like. Often times, the seller just assumes that a "factory reset" will un-do the modifications, but in the case of the Moto X (with all the Write Protect-disable exploits and safestrap), the modifications actually persist through a factory reset.

Well, I followed the directions and it seemed to flash ok. Booted it up, wanted to activate (I canceled that- I dont have service on the phone yet), everything seemed normal. Went back to flash TWRP, same behavior as before. Any other ideas?

A couple more: some individuals have reported that they had issues using a USB 3.0 port. If possible, use a USB 2.0 port to flash the recovery.
If you flashed ALL the partitions in the SBF file starting with gpt.bin (basically manually executed the commands in the XML file, IN ORDER), it -should- have worked.
You might also try flashing twrp from a different PC...
OR
You can try flashing TWRP 2.6.3.1 from here: http://forum.xda-developers.com/moto-x/development/recovery-unlocked-twrp-2-6-3-1-android-t2534850
This version is confirmed to work on all versions up to and including 4.4.2, so as long as you aren't on 4.4.3 yet, you can give this a shot.
And lastly, since I don't know exactly where you got the mfastboot binary, be sure to try the mfastboot binary linked in the 'return to stock' thread. That one is confirmed to work.
2 suggestions:
- try a different TWRP - I'm using a 2.7 that is referred to in one of the threads here
- after flashing > use the volume down button to highlight boot to recovery, and the volume up button to select (execute) that command ... my first time I tried the power button to select it and that doesn't work. I experienced some strange issues when trying to flash recovery if I didn't immediately boot into recovery (don't power down).

The volume-key navigation is familiar to me (Ive had Android devices going back to the Samsung Moment), and I wasnt sure if I was getting into recovery or not since it just booted normally when I select recovery from the boot menu. However, when I specifically boot to recovery with 'adb reboot recovery' I get the tell-tale "No command" screen indicating I still have stock recovery.

If you boot into stock recovery on Moto X, it shouldn't say "No command".... It should show "Dead Andy" - the broken android with the exclaimation point.
Are you trying to do this while android is booted? If so, unplug the USB, turn off the phone. Now hold down VOL DOWN and turn it back on. You should be on the bootloader screen (AP Fastboot mode). Plug the USB back in now
(^ I realize you probably already know the procedure, but good to have it here for others that might visit this thread)
Now VOL DOWN to recovery and VOL UP to boot it
What happens? Do you see Dead Andy?
I just tested the procedure on my phone (after flashing stock recovery back). After I select recovery and VOL UP to boot it, it takes less than 10 seconds for Dead Andy to appear. Pressing VOL UP + POWER brings up the stock recovery menu: reboot, apply update, wipe cache, etc. etc.
EDIT: I also just tried rebooting from within android as you stated you had done. After typing adb reboot bootloader, the phone promptly booted to the Dead Andy Stock Recovery screen.
Nowhere did it say "no command" on either the device itself, or the command prompt from which the adb command was executed...

My MacBook Pro only has USB3.0 ports. I would expect an issue to show some error, though (like in the transfer). It seems everything transfers just fine; it just doesn't seem to take.

I dont really have anything different to try. Ive got another MBP, but its pretty much identical, and I get the same results when I try there. I have several VMs I can try- Ive tried with Win7-64bit (as mentioned in the original post) but that was the same too. I could try Linux too, if I get the time to set one up, but my gut says it wont be any different.

Yes, I see the dead andy image, with the no command message below him.
No, I am doing this from the bootloader. When I attempt to load recovery from the bootloader, I see the white unlocked warning image, then it goes and boots normally. Once into Android, I can issue 'adb reboot recovery' and that's when I see dead andy with the no command message. Confused yet? Cause I am.

I suggest a slight variation:
After you extract the entire SBF file to the same folder where mfastboot resides:
First, boot to bootloader. Next, issue the following commands:
mfastboot flash partition gpt.bin
mfastboot flash motoboot motoboot.img
mfastboot reboot-bootloader
Device should reboot right back to bootloader. Now issue these commands (we are going to use mfastboot for ALL commands, and YES, we are repeating gpt and motoboot again. this is intentional):
mfastboot oem fb_mode_set
mfastboot flash partition gpt.bin
mfastboot flash motoboot motoboot.img
mfastboot flash logo logo.bin
mfastboot flash boot boot.img
mfastboot flash recovery recovery.img
mfastboot flash system system.img
mfastboot flash modem NON-HLOS.bin
mfastboot erase modemst1
mfastboot erase modemst2
mfastboot flash fsg fsg.mbn
mfastboot erase cache
mfastboot erase userdata
mfastboot erase customize
mfastboot erase clogo
mfastboot oem config carrier sprint
mfastboot oem fb_mode_clear
mfastboot reboot
Lets see if we can flash TWRP now. I helped another user on a MAC with a similar issue, and this resolved it for him. I'm hopeful we will fix your issue as well.

GPT stands for GUID Partition Table.
We aren't quite sure why this method works with stubborn flashes, but this is the theory:
We think that if the partition table somehow gets corrupted, the bootloader enforces write protection (on some or all partitions) even if you are unlocked...
The trick is to just flash the partition table, and the bootloader images, then immediately reboot, so the bootloader can load the NON-Corrupt partition table. Once the system reboots, all subsequent partition flashes seem to 'stick' without issue. It seems to involve some sort of 'bug' in the write protection implementation.
Regardless, once it is fixed, so is the issue. You shouldn't need to double-flash any partitions after rebooting like we did this time. AFAIK, all the users who got fixed using the above procedure have reported no further problems.
Just remember to never flash a previous version of android without checking here first. Most users who have to undergo the above procedure tried to downgrade for some reason, and many of them ended up having to do the procedures listed in the "Unbrick" thread (Not fun...)
Glad it all worked out.

Makes sense. Given that the bootloader is the one area you cant easily fix if you screw up, I would add as much protection as possible too. Of course, I would also add error messages... Makes me wonder if there is some hard coded entries in the event the GTP gets screwed up. Has anyone attempted to inspect the gpt.bin file?

Good to know. I dont plan on doing anything fancy, just want root for TI backups, really. I guess Ill see how well flashing the bootloader works again when the 4.4.3 OTA comes around to my phone.

Bricked. Red "Your device is corrupt. It can't be trusted and may not work properly"

Bricked. Red "Your device is corrupt. It can't be trusted and may not work properly"
Following this guide I ended up bricking my Nexus 6. Please ask questions as this is my first time rooting a device.
http://forum.xda-developers.com/showpost.php?p=56938530&postcount=1
After typing "fastboot reboot" my phone begun rebooting, stopped and went to the red "Your device is corrupt. It can't be trusted and may not work properly". Now I am able to get to the fastboot menu. I am also able to get to the android recovery menu. Can anyone point me in the direction to get my phone working again?
Thank you in advance
You can get into fastboot. So restore to stock image. Or since you have custom recovery restore your working backup.
Then read the thread on root. Not just the first post. Read the most recent ones... They are the ones with the most up to date info. Never flash stuff or follow guides with out reading like the last 3-4 pages of the thread as well as the full OP AT A MINIMUM.
1)download google factory image
2)Extract everything in one folder.
3)Delete userdata.img from folder(because once i left it in folder and started flashing images one by one and ended up with empty internal storage.lost everything)
4)use these commands to flash
fastboot flash bootloader C:/image-shamu-XXXXXX/bootloader.img
fastboot reboot-bootloader
fastboot flash radio C:/image-shamu-XXXXXX/radio.img
fastboot reboot-bootloader
fastboot flash system C:/image-shamu-XXXXXX/system.img
fastboot flash boot C:/image-shamu-XXXXXX/boot.img
fastboot flash recovery C:/image-shamu-XXXXXX/recovery.img
fastboot erase cache
5)reboot
You don't have to delete userdata.img... Just dont flash it, and don't use flashall
Your manually typing these commands. Just don't type it. Understand what the partitions are and don't flash the ones you don't want.
And on that point, rather then flash the stock recovery, flash something like TWRP since your trying to root.
Wow. Thank you guys. I really appreciate it. Great group here.
Got it back up and running with 6.0.1 with your help. Since I have gotten this far I think I'll try out some ROM's.
Thanks again.

I have a soft rocked Red Magic 3

Can anyone tell me what this (remote: Flashing is not allowed in Lock State).
What exactly is locked? Is my cell OEM unlocked?
I flashed the wrong TWRP (for the 2017 Red Magic-NX209J) and even though I have been able to unlock my cell via CMD commands; it remains permanently in fastboot mode?
If I send a CMD command to reboot it reboots straight back to fastboot mode.
No form of ADB connect seems to work an my windows PC cannot see/show the cell?
How the hell do I fix this? It's been in this state for a week.
Can anyone help?
Meaby try this?
Then, to unlock your bootloader, enter "fastboot oem nubia_unlock NUBIA_NX629J"
And meaby try the recovery backup instead of TWRP.

Thanks for the suggestion. I have no recovery back up Is it possible to get past TWRP being locked and use CMD to flash the International or chinese ROM? Or recovery image?
Unless tools are developed to unbrick this device I am scared this problem might be permanent
Download this twrp, and then upload it to google drive or something so the rest of us can download it too .

Thanks but what do i do with it? Its all in an asain language?
Link not open bro
The TWRP does not work
Sorry. That link to the twrp does not result in a bootable twrp recovery for me.
I am starting to think my cell is not fixable.
I did not do that much wrong I just flashed the twrp for 2 models of red magic earlier. It only has a fastboot mode. I either get a boot screen then fastboot mode or a warning about the bootloader being unlocked.
Whatever is wrong with my cell prevents ADB connect an the cell is not able to be seen by windows.
This $1100 New Zealand dollar cellphone may be permanently bricked by my mistake.
I might just need to bin it an buy another one.
Lesson learned.
It confusing....
My cell acts like it has a softbrick (can turn off an on an has fastboot options and I have erased it an OEm an bootloader unlocked it)
And also behaves like a hard brick (resists every method of repair).
I just do not understand it or Nubia products. I am unfamiliar with this phone.
Does anyone have any clue how I can see this cell on my windows pc or ADB connect it an boot into TWRP?
Are there any Nubia repair software tools?

Thanks for that. I'm talking about using CMD to totally wipe everything in the cell an reflash the Chinese ROM that came with it. Repair software. Might take months to develop software like that.

Also it isn't a zip. It's some other kind of file. And does not boot into TWRP on my unit
So are you able to unlock your bootloader in its current state?
If you have an older TWRP installed maybe try changing the model on your bootloader command to match it:
fastboot oem nubia_unlock NUBIA_NX209J
If this works then flash the correct TWRP and the boot IMG from your original rom
fastboot flash recovery <new recovery>
fastboot reboot bootloader

Terrapin. Absolutely nothing worked. I am the 3rd person who has had this issue I know of. 2 other xda members had the same issue. One with TWRP like me an the other got stuck in fastboot mode after trying g to flash an apk of Gapps? I think these cells do not like tinkering. But your advice enabled me to be OEM and bootloader unlocked. But always.....straight back to fastboot mode no matter what I flash? My red magic 3 device is currently at a service center with a technician trying to solve the problem. I have 3 repayments left on my Xiaomi Mi9 that has zero flashing issues. O admit i.may be ignorant of the ways of Nubia ?

Thank God. Maybe the Chinese service guy I'm paying will get on xda an try your idea. I'm being lazy saying that lol. Thanks very very much. I will show your post to the service guy who has my red magic 3 or try it myself.
There's no way your a junior member working all this out. I'm a junior member listed as a senior member who makes rookie flashing errors with Chinese cellphones lol.
I will share if I can implement your ideas successfully. Thanks buddy my missus really loved this phone I felt really bad when I incapacitated it.
Fingers crossed.....
I have no idea how did you managed to flash the system.img
C:\adb>fastboot flash system system.img
target reported max download size of 805306368 bytes
Invalid sparse file format at header magi
LE: After this error, somehow it manages to continue and flash all partitions of the system, but after above tutorial, the phone still reboots in fastboot mode and cannot access recovery

Thanks for the help. I do not understand some of the commands an cannot seem to get them right? And I do not understand why the instructions say to cmd flash the image (IMG) via command prompt (which just errors like the strange NON-HLOS command?) Then the instructions say to flash the Chinese rom via otg?
Are you supposed to flash the ROM twice?
Can someone please give me some more detailed instructions as this cell has been non functional about 2 months now.
Planning to fix it an give it to my partner

My suggestions is, download a full sd card update package, unlock the bootloader temporarily,extract the update file and flash the vbmeta.img to vbmeta partion, then flash the recovery.img to recovery partition, after that, try to boot into recovery through bootloader. You have to make sure that you use all the same file from same package, if you are use a low version vbmeta file to boot a high version system (or recovery ) it will not boot. the vbmeta is very important on this phone.

Device is corrupt. It can't be trusted and will not boot

Can't even fastboot flash boot recovery system...and thats all folks...waste of money.

No I installed Chinese v2.27.... Well it's absolute mess like I never seen Android before. Then attempted to flash global again, problems to the point of corruption. I have fastboot flashed all key elements of working Android phone multiple times. Can only get to fastboot after boot screen that I have to do manually. Recovery system is toast.... Guess it's back to Poco F1.... Learned my lesson from junk.

Every time you restart back to the bootloader you need to do: "fastboot oem nubia_unlock NUBIA_NX629J" first

if you stuck in the Device is corrupt. It can't be trusted and will not boot and you are in the Chinese or global rom then flash the stock boot image via adb. well I am using a Chinese v2.27 rom with rooted +gapps and then realized that most of the google apps wont work correctly because of the unlocked bootloader. I tried to lock the bootloader via adb then the message "Device is corrupt. It can't be trusted and will not boot" show up. so I try to use adb to flash the stock boot image then it work. first place the stock boot image to the "Minimal ADB and Fastboot" folder which located in the local drive under program file(x86) then run the command
fastboot flash boot boot.img
fastboot reboot

Bud I put so much effort in last 13 hours to no avail....fastboot erased all partitions, reformatted, reflashed to no avail. Right now it just boots loops on Chinese 2.27 boot splash, I do have Chinese recovery though, but the same otg adapter and pen drive that works on 5 different devices, this damn phone won't read it so even that is out of the question. I wipe my hands clean of it, some things just best to put a bullet through it.

No BS, all I did was flash CN 2.27 over NA Global, after a look at the mess it was I proceeded to flash NA Global back.....no TWRP No Root with SuperSU or Magisk. But in fastboot it does say Root=1, so I guess the CN 2.27 rooted it by default cause I sure as hell didn't. One thing that is bothering me while in fastboot unlock bootloader I can't turn Secure Boot off which I believe is why it won't boot system.

all you need to do is to fix the corrupt image so later once you finish the first step of booting to the phone then you can flash to global rom. if you have the cn version 2.27 boot.img then you can download the adb and use the command to fix the phone
Shouldn't have messed with something that wasn't broken. Now you have a nice brick to use as a paperweight. Hope you get it fixed tho. Good luck.

Hows your phone?..Did it work.

Stock on fastboot

So i have Korean Version V40 (SKT_KR) on android 10 Q, tried to unlock my bootloader.
First thing i tried was flashing abl_a with V35abl using QFIL, but it got soft-bricked and couldn't get into fastboot mode.
Then i installed stock ROM (android 10Q) using LGUP, after that i redid everything, but i flashed abl_b and it got into fastboot mode on V35 bootloader.
So i thought everything was fine and installed ablpiestock.iso thinking it would work. as you know it was for Android pie and i was on Android 10.
Now im stuck on Fastboot, no download mode, not booting into system, and on the bootloader it only shows power off and restart.
Im just very confused were do i go from here.
Model number LM-v4059N (jydypn)
SKT_KR (Korean version)
Android 10
Device State - Unlocked
Also i know my IMEI if that helps

So no, it won't work with ablpiestock on Q. It's unfortunate but the directions, they were written when the person was on Pie, so they wrote it kind of like everyone else would be on Pie.
But what you should have done, before flashing any partition, is to save off the original of what's in that partition. So, you would have abl Q for whatever Q firmware you used lgup to install.
The v35 eng abl will not boot your device. That's because it's Oreo based, it won't boot anything but Oreo roms. But it can be used to unlock the bootloader, then, you flash YOUR original abl back with it, then reboot, and it should be all set.
If you didn't save your newly flashed (lgup) abl partition, then what did u flash? Kr Open 30f ? If so, I have the abl for that. But mention what u flashed and maybe someone will have it.
cheers

ahhh good, then follow this link and you'll find the boot+twrp image you need.
So with fastboot, flash this to your current slot boot partition. Then flash this abl to the abl partition. Then, boot to recovery, hold appropriate keys to do that.
follow steps to get recovery / now twrp. If it asks for pw, just cancel. Format data, then reboot recovery. Then flash magisk and dm_verity and you should be all set.
this is abl attached.

First i fastboot flash abl_b kor_30f (im on b part)
Then i fastboot boot twrp
Them Resart into TWRP using power down + volume down
Then go from here?
Because i get error like this should i also flash to abl_b only?
I renamed abl_b to new, and twrp to boot for easier usage

So, no. First and foremost, don't flash anything to anywhere if you don't know what yer doing. That can result in trying to flash too big of an image to a partition that is too small, and you'll the overwrite the images near it, which could (soft) brick the device.
any abl image is only suppose to be flashed to an abl partition. Any Boot image is only suppose to be flashed to a boot partition, etc.
I'd suggest read the directions in the guide again, do ea step one at a time, if yer unsure what to do at any step, post in here, and one of us can clear it up.

So, I already told you... DO NOT FLASH WRONG PARTITION IMAGES TO WRONG PARTITIONS!!!
You just indicated trying to do exactly what I told you not to do!! You tried to flash the boot+twrp image (that's a BOOT image) to the abl partition!! THE ONLY THING you flash to an abl partition is an ABL IMAGE! NOT A BOOT IMAGE!!
I understand yer new to this, but don't make the mistake of hacking around doing anything u think **might** work. That's the wrong approach, because it could easily make things much worse than they are.
So again, what are you trying to do? One STEP AT A TIME, tell me the state of the device and what your goal is, I'll try to help you get there, but you have to have patience, don't try to run before u can walk.

okay. So from what you're saying, your current slot (be it a or b, I don't think we know), has the v35 eng abl flashed to the abl partition, that's why all you get when you try to boot is FastBoot.
To install a kdz (not dmz) and start over, you need to have download mode working, as I think you know. To get download mode to work there are some partitions that have to have the same variant and version, they can't be 'mismatched' for it to work.
And since you don't seem to have backups of the files your flashed over, the best I can recommend is to follow this link. In that link are the files needed to get lgup to work. They should ONLY be flashed to the exact partition they are for! Boot to boot, laf to laf, etc etc. (the only one in there not to use is the one with twrp in the name).
They would have to be flashed with qfil, which I think u have set up and used already. So once you've flashed them in qfil, exit out of qfil by holding pwr button and vol dn button. Then, when u hear windows chime (meaning exit), release pwr and vol dn buttons but then press vol up button. That should take u to lgup (download mode) and you can flash a kdz and start over.
Do that, and we'll go from there. cheers

They should ONLY be flashed to the exact partition they are for! Boot to boot, laf to laf, etc etc. (the only one in there not to use is the one with twrp in the name).
They would have to be flashed with qfil, which I think u have set up and used already. So once you've flashed them in qfil, exit out of qfil by holding pwr button and vol dn button. Then, when u hear windows chime (meaning exit), release pwr and vol dn buttons but then press vol up button. That should take u to lgup (download mode) and you can flash a kdz and start over.
Do that, and we'll go from there. cheers

They files you shared is for 30c, mine is 30f (Korean version).
Is it okay to use it?
Also is there a certain order do i have to go through? like boot first etc?
cheers for the helps

yes, I know they are not what you currently have. But it will work to get to lgup, not to boot the device, only to get to lgup.
there's no order, I would have told you an order if there was one.
just re-read what I said. This allows you to go directly from qfil to lgup, use the key combo I mentioned.
It's at that point you can re-flash kor 30f, and start fresh.
Im still getting the same error.

you're suppose to be using qfil, not fastboot.
But how would i enter QFIL if i cannot enter 9008 mode?
why are u unable to enter 9008 mode?

I did now, thank you
I was just having problem clicking volume up down button so i thought it was only possible if the phone is booted.
Successfully installed the recovery files and booted into download mode.
Downloading original kdz and hopefully do all this all over again, this time backing up the files
Thank you for all your troubles, you single handedly helped me save my phone.

Another surprise, when i tried to install kdz on the phone, it says:
Error: 0x6004, CrossDL
judypn_lao_eea>@judypn_la
Both refurbish and upgrade options show same result.
This is the same version that i successfully flashed before
edit: shoot, i downloaded the wrong version

Look in the thread on unlocking in the guides forum, you'll find the information in there to deal with that problem. cheers

Great news, i flashed kdz using patched LGUP with custom cmd line. Now its working as intended, it shows OEM already unlocked in dev options. i patched abl_a to get magisk working ( i think my active slot is A now).
So i got root and magisk, but my goal is still have TWRP and install custom ROM.
So from what i gathered, i install v35 on abl_a, boot into fastboot, flash twrp to boot and flash orignal abl back and restard bootloader.
Or can i just flash twrp into boot_a in QFIL?
cheers
