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.

Sounds to me like wrong lgup it's tricky to find the right one, you need the LAB version.

So I rooted my device and life was good than I made something a system app and then I deleted it. :facepalm: Next thing I know I reboot and it comes to the unable to test corruption screen and the led light keeps flashing blue. I still have TWRP. Can it be saved?
I have access to fastboot via the bootloader screen. Can I flash from there?
Edit: and I a guess as soon as you start in twrp adp is activated . So I only need the kdz?
You can try the KDZ because that's basically fool proof, but you can also try to manually flash the partition image for the one that's broken. I think that's the system partition in your case.

You're best bet would be to put it in download mode and flash the latest kdz using LGUP or uppercut. I've always used the original LGUP but seems like most now use uppercut and seems like uppercut is probably a better choice. You will have to reflash TWRP after you get back up and running and root as well as using the kdz will replace TWRP.
Sweet. It's alive again, but I can't access bootloader via adb reboot bootloader.
Edit: nevermind. I didn't update.

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?

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.

Detailed in the instructions for US998 Pie, as that has the most problems.
Previous process:
Started from unlocked H931 Nougat
I'm afraid I actually forgot the precise order... maybe Nougat US998 -> Oreo, maybe Oreo H931 -> US998... Of course using Frankenstein method.
Using WTF..! method unlocked bootloader (I'm pretty sure at some point I also had twrp, and again, may have been prior to US998/Oreo flash... order).
Because of network problems flashed H931 Oreo, 2 years stable.
Current problem:
Flashed US998 Oreo from here: https://forum.xda-developers.com/lg-v30/development/us998-lg-v30-us998-us99820a040330-kdz-t3786337
Tried flashing US998 PIE from here: https://forum.xda-developers.com/lg-v30/development/us998-lg-v30-us998-us99830a000704-kdz-t3952256
In LGUP instead of refurbish I clicked partition dl.
Phone was stuck in bootloop. I tried the button dance to Master reset, worked, however the erased system wasn't able to boot before anyway, how would this help I don't know. The bootloop stays.
Hoped to reach familiar Download mode, but couldn't even power the phone off (in no way from across the forum). Opened the phone, disconnected the battery - it's off. Tried to enter download mode... doesn't work. At least it charges. Tried to boot, entered bootloop again, master reset, bootloop again, disconnect battery.
Found this: https://forum.xda-developers.com/lg-v30/help/download-mode-doesnt-anymore-t3973801 , which leads to a possible solution here: https://forum.xda-developers.com/lg-v30/development/rom-fw-lg-v30-joan-us998-30b-twrp-t3973811
I searched the comments, apparent solution was entering master reset menu and clicking yes in the dialog menus, which should start TWRP. I guess I don't have TWRP, because this does nothing much. A screen saying erasing appears, then goes to the same bootloop.
Bootloop, Download mode doesn't work, cannot acces TWRP. (soft brick)
Found no previous solution to work. (possibly couldn't find it)
Is there any help for me? Should I start looking for something less LG?
have you fixed it? Have you unlocked your device's bootloader yet?
If you have unlocked the bootloader then flash the laf.img file
---------- Post added at 05:28 PM ---------- Previous post was at 05:23 PM ----------
If you want to update android 9 us998, please kdz via ROM h93030b to install twrp, then flash us99830b.zip via twrp
give it a try
Unfortunately not yet. Thanks for the tip, but until I find a way to boot anything on the phone, I guess I won't get to flashing.
I think @thao12345 is saying that (1) if your bootloader is unlocked (it must have been if you ever installed TWRP, unless you relocked it) and (2) if you are currently on US998 ROM, then you should have working fastboot flash commands, and you can fix almost anything.
Boot into fastboot from power off by holding Vol- while plugging in the cable. Of course ADB installed on computer. Test with "fastboot devices".
From there you can use "fastboot flash recovery twrp.img" to get TWRP, or "fastboot flash laf laf.img' to fix download mode. I believe laf.img can be found in the TWRP-flashable US998 ROM thread.
Once you have working download mode, the next step is to temporarily flash US998 Nougat using Partition DL and the latest Pie compatible LGUP. This should help clean up the phone.

right. If the phone is in us998 or h930, you can flash the laf.img file.
If not in the two modes above but get bricked then you can try the ways to enter "EDL qualcom 9008" mode then rewrite the partition using a tool such as QFIL

If you can go to twrp recovery, you can go to reinstall the partition
If brick is black then try qualcom 9008 mode to rewrite the partition (I used to succeed this way)

I'll be honest, I ask because having seen your many posts in various threads here recently, all very similar to the one you posted here -- sharing no real information -- I think you're most likely a bot, trying to build post count before dropping a spam payload.
That is presumptuous on my part and I may be wrong. If so I apologize deeply and will update this post after seeing your response.

Prerequisites
Unlock phone using the guide here: https://forum.xda-developers.com/t/guide-how-to-unlock-bootloader-of-lg-g8x.4198025/
Do not restore abl before rooting.
Magisk Patched Boot (20e, Indian Variant): https://drive.google.com/file/d/1s2A7RUOptXer5LGMtbGV9SKg0kcyL_NP/view?usp=drivesdk
1. Download the magisk patched boot.
2. Copy it over to your fastboot directory.
3. Connect phone in fastboot mode.
How to put phone to fastboot mode?
#1: Using Button Combination
Power off phone, press and hold Vol- and insert usb cable. You’ll be in fastboot
#2: Using ADB
Connect phone to pc, enable USB Debugging. Then run this command
Code:
adb reboot fastboot
4. Now run the command
Code:
fastboot flash boot Magisk_Patched.img
fastboot reboot
5. Download and install Magisk Manager
6. Done! Your phone is rooted now.
To restore Network follow the guide in bootloader unlock thread...
If you have a different G8X variant or are on a different firmware
1.Backup boot_a or boot_b using QFIL (Partition Manager>Read Data, Check Bootloader unlock guide for more details)
2. Install Magisk Manager
3. Click on Install and use Patch image function.
4. Save the boot image to pc.
5. Flash it in Fastboot using the command given above.
Known Issues: FP is broken
Thankyou
(copypasta'ed from the other thread)
For those who have yet to do this, I suggest extracting boot_a/b at the same time you flash the abl image. Prior to doing the fastboot oem unlock, use the Magisk patch file option (installed on the same or another device, and doesn't need to be rooted) to create a rooted boot image using adb push/pull. Once you fastboot oem unlock, go back into the bootloader and instead of fastboot flash boot, you can fastboot boot magisk_patched.img.
Once you go through the setup, you can open Magisk, which will download and install the full Manager app, at which point it will most likely reboot. You will need to fastboot boot again, and you should be able to do a normal Magisk install. I've usually found that as long as the patched boot is of the same Android version and within a few month of the patch level, it'll boot happily enough to do this. Afterwards, you can restore your abl image as you no longer need to use fastboot commands.
Doing this allows Magisk to save the stock boot image, and also allows you to get OTA updates by restoring the stock image right before any updates. Otherwise you will never be able to do an OTA update as it checks if the boot partition has been modified before installing the updates. Since there are no kdz for the US carrier models, your only other option would be to "brick" your device to try get your carrier's service center to restore a working firmware image.

Sorry I posted in the wrong thread. I've deleted the contents, but wasn't able to delete the post itself
Guys, I am trying to follow this guide using the "different variant" method, but as soon as I boot after flashing boot.img the touchscreen doesn't work. Only way to get it back is to flash the boot_a.bin and boot_b.bin using QFIL. What am I doing wrong?
Is there a magisk patched image for the g850u20i
Is there an update for magisk patch image for 20b (unlocked US variant)?
Edit: Got my 20b version rooted.
Downloaded stock rom for the G850QM20b, extracted the kdz file to dz to .img grabbed the stock boot_a.img file and ran it in Magisk manager app, took the converted .boot.a.img (now renamed magisk_patched_clT14.img) and dropped it in platform tools, went fast boot, then flashed it. Came back up great, no issues and root access is clear.

So my understanding is you can have a rooted phone, but FP will be broken no matter what and possibly audio as well. You can fix this by reinstalling a Pie version from KDZ, fix it then reinstalling a 10, but then the root will be gone (but the bootloader remains unlocked). Is this correct?

Yes, rooting will be gone and Bootloader remains unlocked forever. You have to root it again in A10
For anyone in the future: you can have both root and fingerprint. Follow the bootloader unlock guide up to the point where you have to backup your boot_a. After that you don't use the patched boot_a in the instructions, instead patch your own version with magisk and flash that instead with QFIL. I now have a working V20h EU version with root, fingerprint and working audio.

I do. But it's an EU version, so I'm not sure it would work for you. However it's easy to just make your own!
- Install Magisk manager on the phone. You don't need open bootloader or anything for that
- Get your own 20f boot_a using QFIL
- Copy your own boot_a to the phone or on an SD card
- In Magisk Manager you choose to install magisk, select patching an IMG file method and give it the boot_a
- If Magisk reports success you'll now have a magisk_patched_boot_a file. Copy that back to your PC
- Using QFIL flash that in place of your original boot_a
- Keep a copy of your original boot_a thou, you can go back with QFIL at any time.
- If you mess up royally and the phone doesn't boot, you can still recover it by re-flashing your firmware with LGUP 1.17. You'll have to download your region's firmware for that and you'll loose all data, so make a backup beforehand!

Hi, thanks for sharing the steps!
I followed your steps but don't have audio/network/fingerprint after flashing patched boot. Later I also tried to restore abl_a/b, then I had audio and network working, but still no fingerprint.
In my case, fingerprint stopped working once bootloader is unlocked, before even flashing the patched boot.
Did you have working fingerprint right after you flash patched boot? Did you restored abl_a/b?
I also tried to follow another post to get fingerprint working, but I can only find 10b kdz of my variant (twn), I downgraded to android 9 using that kdz, still cannot get fingerprint to work.

I also messed up at first, since there were no ready-made boot_a for my region/version I just grabbed the indian one for 20e, and yes, that did break my audio, fingerprint and possibly network, I didn't test that one. I did have a KDZ for my region thou, so I flashed back a 10c version, I needed the 1.17 tool, not the 1.14 or 1.16 one (those did not work) and in my case I needed the second version of 10c, not the first one to fix the fingerprint. After flashing 10c I did all the steps and regained my fingerprint reader without an issue (so no, it did not work right away, I did need to go into the service menu and do the test), audio and network also worked right away. After that I flashed my latest KDZ (20h) and using magisk manager made my own boot_a and was able to root with a working fingerprint. I did not dare to update Magisk after this thou, I only needed it to grant root for my adblocker, and it's hidden from everything else, I don't think I'll ever even start magisk again, so I don't really want to update it either.
Did you restore abl_a/b at all? I can only get into download mode (to use LGUP) after I restore abl_a/b.
Anyways, I think flashing using LGUP overrided the abl, and that's why audio and network worked right away (to my understanding)
My LGUP tool worked fine, but there only 10b for my TWN variant, I couldn't find 10c anywhere... (only 10b, 20a, 20b available)
I never flashed other's patched boot, I used QFIL to get my boot_a.bin and patched it using Magisk on another phone. Then I used fastboot to flash boot. (I did this right after unlocked BL, all before I restored abl).
Did you also use QFIL to get boot_a or did you use KDZ extractor? I'm having problem with my KDZ extractor tool, encoding issue or sth.
My variant is G850EMW, should I try the indian 10c kdz (which is also G850EMW)? Would that work? Not sure what risk cross region flashing poses, or even if LGUP would let me flash it at all.

No, I did not restore abl_a/b, and after KDZ the bootloder remained open, so there is no need to, the phone still reports an open bootloader at boot. If it _does_ override it thou it seems it's not neccessary to have, as I could root the phone and could keep the open bootloader anyways.
I used QFIL to get my own boot_a, and used it again to flash it back too.
My EU (Hungarian T-mobile) version is also G850EMW. My understanding is that if LGUP lets you flash a KDZ it's probably gonna work, but in the worst case scenario as long as you have a known good KDZ for your model you can always come back to that, so I guess you can experiment?
I've also only found a 20b version of KDZ for TWN, but it's release date is similar to 20h in the EU, so maybe these numbers doesn't mean they are the same KDZ, only that 20x meant it's Android 10 and the letter is the revision. Based on this it's possibe you don't need a 10c to restore your fingerprint, just try the earliest 10x KDZ you can get your hands on (for me the 10c was the earliest one). Alternatively you can try the 10c I used for mine, it's EU Hungarian, but the default language is still English and you'll re-flash it anyways: https://lg-firmwares.com/downloads-file/21667/G850EMW10c_00_OPEN_EU_DS_OP_1122
Hi everyone,my phone totally dead and the only 1 working is edl mode.All my partition backup corrupted.If anyone can help me provide all backup partition i really appreciate it.
You can attempt to flash the KDZ and repair your phone. Try that first, and I'll upload my custom ROMed partitions if necessary.

Get the kdz you want and run it through this kdz extractor: https://gist.github.com/haise0/f3c1f24b0a7a9150603dfd00985c0042. Then flash each of them in qfil after you backed up your partitions. Then you should be able to flash the phone in LGUP. I lost my serial in the process but the phone works after having been stuck in a fastboot loop.
