If by "recovery" you mean TWRP, yes.
If you have unlocked bootloader and TWRP, unless you are flashing a TWRP flashable zip, then you need to flash full H930DS KDZ using Refurbish mode. Yes, you will lose TWRP recovery, but you can add it back with fastboot.
All H930 variants firmware (including H930DS) has fastboot. What have you flashed that doesn't have fastboot? Korean firmware does not. They have to flash to H930 variant firmware for bootloader unlock and TWRP installation, then flash to TWRP flashable zip to get radios back.

Thank you for your reply ChazzMatt,
But the problem and that my device is stuck on the LG Logo.
And if I press the power + Volume Down button, the screen turns black and then restart right behind.
So do you think I can flash the ROM KDZ with LGUP?

If you've lost download mode and fastboot mode then you'll need to do the button dance to get into QLD 9008 mode--then pay for a remote JTAG Octoplus box repair fix for $15-$35 (some give $20 discount to XDA members) on Ebay
EDIT: Found him: https://forum.xda-developers.com/member.php?u=6038524 (MFKilla). Here is what he offered few days ago: "For all xda members i have -20$ discount) Im from Moldova
And on my service no need disassemble the phone =)

We are in the same boat my friend. I have a V30 ( V300L ) LG+ korean operator. I have tried to update to pie several times without success. I have used a kdz from
lg-firmwares.com so I think I have used the correct software. LG bridge says it can't read the information of the cellphone. Also I have never received an OTA.
I have used LGUP for developers to upgrade it. Once the process is completed the phone gets stuck at the LG logo. I can fix this by downgrading to OREO using the refurbish mode of LGUP. It seems that my cellphone is gonna stay on OREO for long time. At least it hasnt bricked yet.

Bricked LG G5

Hello,
it seems that I bricked my H850.
All I can do at the moment is enter Download Mode, but LGUP crashes at the beginning everytime.
I can enter fastboot mode but I cant boot recovery, if that is possible I could flash a rom.
Can I flash manuelly a rom in the fastboot mode?

Redownload KDZ file, make sure it's not corrupted*
Try on multiple PCs*
Try different versions of LGUP*
Right click on LGUP and run as administrator*
Sent from my LG G5 using XDA Labs
- I have tried different KDZ. 10c; 10e. Error is "primary gpt" at 10%.
- I have tried at 2 computers and old and new version of LGUP.
- LGUP starts only as administrator
Unfortunately you may need motherboard change.
Same thing happened to me and I had to send the phone for repair.
Fortunately I was covered by the warranty

Maybe try another dll file somebody extract dll from v10i and that whats help me with similar problem. But check upgrade in lgup not refurbish.
My Phone is working again.
LGUP and LGBridge both didnt want to flash the G5.
With fastboot I erased and formatted userdata, locked bootloader. I tried a lot of things that I dont know anymore.
Result is that LGUP stopped with the same error but LGBridge flashed 10i and now the phone works again.
Now LGUP works again and I can flash every KDZ, LGBridge is doing something different that it could flash the G5.

Yes. LG UP is using LAF to flash.
LAF Is the LG Advanced Flash. When you hold vol up and insert your USB cable to get into download mode, aboot loads a partition called LAF.
runningnak3d explained it well in the H932 rooting thread
Longer explaination:
H932 has bootloader unlocked but no flash commands. They can flash stock firmware with LG UP tho.
The plan was to get dev version of LG UP which can flash single partitions and use it to flash /boot that was patched with Magisk.
This failed because LAF will not allow to flash anything that is not RSA singed by LG. And that's where they got stuck.
They can flash stock firmware or stock partitions extracted from official .kdz tho

LG UP should automatically put the phone into download mode when you start the .kdz flash otherwise you can do it manually by just following 3 simple steps:
1. power phone off
2. hold volume up
3. put in usb-c
...you're in download mode

Don't quite understand. If you haven't factory reset your phone, then you should still have TWRP. Boot to TWRP with fastboot commands or button dance?

Europe H930 doesn't convert to North America US998 for bootloader unlock, among other reasons as it already has fastboot flash commands.
But he probably used LGUP to downgrade to necessary pre-July 2018 H930 KDZ firmware -- unless he was lucky enough to already have that on his phone.... Those of us in the beginning of WTF didn't have to downgrade to anything.
There's also dev patched LGUP in the Europe H930 KDZ thread. He's had to have seen it...

See bottom of post #1 in this thread:

Unless you were already on pre-July 2018 firmware when you unlocked your bootloader, you had to use LGUP to temporarily downgrade earlier firmware. Since your bootloader is already unlocked you don't have to downgrade, but you do have to re-flash stock firmware with LGUP. It can be the most recent, if you wish. Then you will use fastboot flash commands to re-install TWRP.

Yes. You can either choose Refurbish or DL Partition (but choose all partitions). This will wipe your phone, so save off anything you don't have stored elsewhere. Your bootloader will remain unlocked. You will then reinstall TWRP via fastboot flash commands.

If you choose "upgrade" it will only overwrite the parts it thinks needs updating. I think you need a fresh install of all the stock firmware as something seems corrupted from your ROM installation.
Since your bootloader is already unlocked, you can actually flash the newest H930 firmware. 20R is sort old. I think 21O is the newest... But it's your choice.
Then, you would reinstall TWRP, reflash the no root check and no encryption files, and reflash Magisk -- like when you first unlocked the bootloader and rooted.

V30 bricked while trying to root (no download mode,factory reset disabled)

Hi guys I bricked my V30.
I just try root my V30 so i flash H930 kdz to V30.(partition DL)
and i try factory reset on h930 rom.
but i see kill switch , i'm panicked and i flash korean kdz to partition DL. i think it was my fault. in korea rom, i saw no command with android.
and I flash h930 kdz. then i can't get in download mode. i should have used an editor, and flash korean kdz to refurbish...
but i didn't .
I have to go customer center.
there's no way?

Thx. Now i can see killswitch logo and h930 boot logo, no killswitch logo with no command logo. And fastboot mode says enable usb debug.
Get the LG software for windows, connect your phone and you might be lucky and it will download and install the right KDZ. Saved me once with my G5.
I just solve the problem to using octoplus. Thanks.

Sadly might have bricked my H933

Hi guys, dealing with a H933 --> US998.
TL;DR - stuck on LG logo, no download mode, no fastboot, master reset does not work, LGUP (patched or unpatched) doesn't recognize phone, computer doesn't recognize it either.
----
Frankenstein method followed correctly, and had unlocked bootloader + root.
Followed H933 specific steps to install AOSP/Linage ROMS. Attempted to install Lineage 16.0 and flashed Lunar kernel. Booted to animation logo and didn't get past that.
Decided to revert back to stock Pie by flashing one of the US998 kdz's. To be honest with you, I tried a few different ones and everything was working fine (I went from Nougat --> Oreo --> Pie in order to bring myself back to Pie firmware to try Lineage install once more but with stock kernel).
This time, phone wouldn't move past the LG animation (right after the logo).
At this point, I lost access to download mode - but I still had fastboot. Installed TWRP again through fastboot and attempted to flash TWRP-JOAN_H933_CANADA_20i.
Lost unlocked bootloader image - lost access to fastboot and recovery - and still didn't have download mode (it would not pass the original download mode image) and would not be recognized by LGUP (patched or unpatched). The phone would be stuck at LG logo, and keep rebooting.
At that point I decided to try a Master Reset. On the second YES, it would hang, and then go back to the LG logo bootloop. Phone does not get recognized by computer.
I know I messed up in numerous points. I got overzealous and likely didn't pay enough attention. Spent all night trying to resurrect it, but to no avail. Any advice for me? Or is the device fully bricked? :crying:
Greatly appreciate any feedback and assistance. Thank you in advance.
Sorry to hear that. I think you have four options.
1) Reach out on the telegram v30 forum to someone with an Octoplus box to remotely resurrect your device.
2) Send it in for "repair".
3) Do it yourself, see https://forum.xda-developers.com/g4/general/guide-unbrick-via-external-sdcard-qfil-t3748946.
4) Buy a new phone.
The third option isn't hard, but may involve a lot of work so I'd go with the first one.
don"t worry too much, that phone is almost unbrickable, at least you are really unlucky, you will revive it. Wait for @ChazzMatt to give you some help before giving up hope entirely
Meanwhile, I can give you some advice because I was stuck one time on LG Logo, you were on which firmware when it last booted up?
While it is bootlooping, connect it to the pc, do a soft reset with power and volume down buttons, release them when the screen goes black and immediately press the volume up button to access fastboot menu, and if PC doesnt recognize it, shut down the phone by selecting it with volume button.
Deconnecting the phone and press volume down while reconnecting it to the pc to try to go to download mode and kdz your phone.
Somewhat working
Hey guys - brief update. I got back to US998 Oreo with bootloader unlocked and root. I tried to upgrade to US998 Pie by flashing US99830b.zip in TWRP following all the steps, and now the phone doesn't boot again and gets stuck on the LG Logo. Download mode shows "Now waiting For Any Connection" and doesn't detect PC. Any idea how to get this to work so I can flash back to US998 Oreo and just stick there?
Update: Flashed US99820H and back in running order. I still wonder how to get my phone onto Pie while keeping bootloader unlocked and have root, without having the phone get stuck.

Thoroughly discussed in the US998 Pie KDZ thread. Top of post #2 (one method), all of post #6 (three different workarounds).
If none of the 4 methods work for you, there are no other answers and you have to wait for another US998 Pie KDZ.
I've struggle for a couple days and finally i can flash pie stock rom to my us998. What i did :
1.Refurbish us99820h lgup, boot os
2.flash and boot twrp via fastboot
3.flash magisk,dm verity, rctd, via twrp...format data reboot format data then magisk again
4. Boot OS
5. Boot recovery then shutdown
6. Partition DL h93310h lgup except RECOVERY AND RECOVERYBAK
7. Boot OS .... Once your lg logo appeared ( BEFORE LG ANIMATION ) press and hold vol down + power. Release power and hold it again IMMEDIATELY once you see LG LOGO ( BEFORE LG ANIMATION ) click the "yes" and "yes"
8. You got the twrp
9. Flash us99820e + magisk via twrp , boot up
10. Refurbish us99820h, boot up
11. Do step 2 and 3
12. Boot OS
13. Boot recovery
14. Flash us99830b via twrp then flash magisk
15. Done u should have pie now
What you are describing is Method #3 in post #6 of the US998 KDZ Pie thread.
It's the workaround which has the most success but is also most complicated.

Yes.
What you are talking about is you can't run LOS-16 ROMs on stock Pie. You have to downgrade back to Oreo, and even then you will forever have to run permissive kernel with Oreo firmware for camera/flashlight to work since you once flashed stock Pie.
You would downgrade to Oreo 20h, flash all those steps (H933 Nougat, etc) and eventually get back to US998 20h and then stay there.

Yes.
What you are talking about is you can't run LOS-16 ROMs on stock Pie. You have to downgrade back to Oreo, and even then you will forever have to run permissive kernel with Oreo firmware for camera/flashlight to work since you once flashed stock Pie.

1) On my backup V30+ which is on stock US998 30b Pie (but doesn't have a SIM card inserted nor even signed into my Google account), it's connected fine to my home Wi-Fi network so I know it's not a stock US998 Pie issue...
2) This happens even on public free Wi-Fi networks? (Here in the U.S. we have McDonalds, Starbucks?) That would give you clue whether it's one particular router or all your phone has problem with. Or possibly problem with the type of encryption you have on your router.
Usually that message means the router is rejecting the device. You just have to figure out why. But is it one router or all?
3) If one particular router, try rebooting the Wi-Fi router itself.
4) Make sure you don't have any kind of router whitelist for certain devices or MAC addresses and your phone is not included. Or that you don't have some older b/g Wi-Fi chipset standard set; this one is not likely but I had that happen for an older Wi-Fi printer when I had "N" or higher set on my router.
5) On the phone, try forgetting the Wi-Fi network and refinding it. Enter in the password again.
6) Almost last, on the phone try the Network Settings Reset. (See screenshot from US998 30b Pie.) It will reset all network settings including Wi-Fi, Bluetooth.
7) Last, try Factory Reset?

Hi guys, dealing with a H933 --> US998.
TL;DR - stuck on LG logo, no download mode, no fastboot, master reset does not work, LGUP (patched or unpatched) doesn't recognize phone, computer doesn't recognize it either.
----
Frankenstein method followed correctly, and had unlocked bootloader + root.
Followed H933 specific steps to install AOSP/Linage ROMS. Attempted to install Lineage 16.0 and flashed Lunar kernel. Booted to animation logo and didn't get past that.
Decided to revert back to stock Pie by flashing one of the US998 kdz's. To be honest with you, I tried a few different ones and everything was working fine (I went from Nougat --> Oreo --> Pie in order to bring myself back to Pie firmware to try Lineage install once more but with stock kernel).
This time, phone wouldn't move past the LG animation (right after the logo).
At this point, I lost access to download mode - but I still had fastboot. Installed TWRP again through fastboot and attempted to flash TWRP-JOAN_H933_CANADA_20i.
Lost unlocked bootloader image - lost access to fastboot and recovery - and still didn't have download mode (it would not pass the original download mode image) and would not be recognized by LGUP (patched or unpatched). The phone would be stuck at LG logo, and keep rebooting.
At that point I decided to try a Master Reset. On the second YES, it would hang, and then go back to the LG logo bootloop. Phone does not get recognized by computer.
I know I messed up in numerous points. I got overzealous and likely didn't pay enough attention. Spent all night trying to resurrect it, but to no avail. Any advice for me? Or is the device fully bricked? :crying:
Greatly appreciate any feedback and assistance. Thank you in advance.

How did you unbrick your phone? I'm in the same boat as you. I can get to the Download mode, but not past the blue dot image. If I try to master reset, the phone just restarts after the second time I select yes. It's been bootlooping like this for a while now. For context, I was on US99820H(dirty flashed via twrp) when I tried to flash H93330k. @ChazzMatt, I know this is a long shot as what I did was incredibly stupid, but is there anyway I can get out of this?

Hey guys - brief update. I got back to US998 Oreo with bootloader unlocked and root. I tried to upgrade to US998 Pie by flashing US99830b.zip in TWRP following all the steps, and now the phone doesn't boot again and gets stuck on the LG Logo. Download mode shows "Now waiting For Any Connection" and doesn't detect PC. Any idea how to get this to work so I can flash back to US998 Oreo and just stick there?
