(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.

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 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.

I have a copy of boot_a but in the fastboot it tells me that I am using abl_b and I don't know if boot_a is compatible with abl_b and i can't enter EDL mode
[LG G8X ThinQ Guides, News, & Discussion] zdanee:
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?
[LG G8X ThinQ Guides, News, & Discussion] foenicxxx:
Yes, rooting will be gone and Bootloader remains unlocked forever. You have to root it again in A10
[LG G8X ThinQ Guides, News, & Discussion] zdanee:
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.

[LG G8X ThinQ Guides, News, & Discussion] zdanee:
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!

[LG G8X ThinQ Guides, News, & Discussion] james508959:
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.
[LG G8X ThinQ Guides, News, & Discussion] zdanee:
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.
[LG G8X ThinQ Guides, News, & Discussion] james508959:
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.
[LG G8X ThinQ Guides, News, & Discussion] zdanee:
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
[LG G8X ThinQ Guides, News, & Discussion] james508959:
thx so much for your detailed reply!

So it seems I must have done something wrong...

After I unlocked bootloader, I cannot get into download mode, it only showed download mode for a brief moment, then it showed that the phone failed some safety test, showed the link: g.co/ABH and after a while it reboot into fastboot mode.

Maybe it's beacause I use fastboot to flash the patched magisk boot.img, instead of using QFIL?

Also, did you followed the simple 4 steps or the original many-steps guide to get finpgerprint working? I only did the 4 steps, because I'm not sure how to safely re-lock the bootloader. I assume the phone need to be at stock everything? EDL mode is kinda scary lol

The earliest KDZ I could find is 10b, I think the phone at first shipped with 10a when it just hit the market, but I could not find 10a kdz anywhere.

I will maybe try 20a twn kdz (seems like a long shot tho) and 10c eu kdz, hopefully something will work!

thx again.
[LG G8X ThinQ Guides, News, & Discussion] zdanee:
I flashed everything with QFIL, not fastboot. You can get into download mode even when the phone is unable to boot properly. If you can get into EDL mode try to restore your unpatched boot_a with QFIL and try again! I know it looks scary, but it's also the tool you can bring back even a completely bricked phone as long as you have the backups.

I followed the new, 4 step method for the fingerprint, I did not re-lock the bootloader.
[LG G8X ThinQ Guides, News, & Discussion] kgirlx:
Could you please share your patched boot.img file for stock US unlocked... I'm thinking of getting this phone and any help is appreciated. Thanks
[LG G8X ThinQ Guides, News, & Discussion] zdanee:
I would advise to make your own patched boot.img, it's easy to mess up the audio or the fingerprint reader with a boot.img not meant for your device. Making your own is easy too: you install Magisk Manager on your phone, while doing the bootloader unlocking tutorial you save your boot_a with QFIL, reboot the phone, put the boot_a into magisk manager and patch it that way, then once again using QFIL load your very own 100%-guaranteed-for-your-phone boot.img.
[LG G8X ThinQ Guides, News, & Discussion] Buzzy42:
I just got the US Unlocked G8X (G850QM) and am really confused about where to start, since a lot of the guides seem to assume you're starting from a 20 Android 10 ROM.

Mine came with Android 9 (G850QM10C). I am confused about all of the people saying if you unlock the bootloader, you will lose fingerprint, but some people say you can roll back to Android 9, and some say that you can just fix it by using your own boot.img that you can patch. I'm confused because it seems like different threads lead to different conclusions.

If I just unlocked the bootloader while I'm still on 10C (Android 9), would that bypass the problems? and then I can update it using the 20e KDZ? (how do you do that and not lose root? Or do you lose root and you just have to re-do it?)

Or should I let it update to the latest OTA, and then start the bootloader unlock and root process, patching my own boot.img, and it should work ok?

Basically, I only want to root it at this point if I can keep the fingerprint reader (and all the other functionality of the phone)

Thanks for help!
[LG G8X ThinQ Guides, News, & Discussion] Buzzy42:
Thank you!! I will definitely be trying this in the next few days, just need to clear up some time to ensure I'll be able to chase down any issues that might arise although with such clear instructions I am hoping for the best!
[LG G8X ThinQ Guides, News, & Discussion] Buzzy42:
Worked fantastic! I stayed on Android 9 to do the unlock mostly because I wasn't entirely sure the KDZ I had was the right one and didn't want to get stranded. Ended up to be a good idea, even though I cleared my FP and PIN code, the FP didn't want to work after the unlock. So I went through the test and got it fixed.

Upgraded to Android 10 (which seemed to switch the boot partition from A to B in my case, had to flash MAgisk to B to get it to finally work) and almost everything is perfect! The only weird glitch I am noticing is I can't update Chrome or Webview to the latest versions, everything else upgrades fine but when I try to update them in the store it just pretend to try and then goes right back to showing "Update". Very strange... doubt it's related to all this but who knows.

Very happy to have a fully functional, rooted, unlocked G8X, thanks again!

Hello all..!

Kindly help me understand this: if I unlock BL and root (by first downgrading to a 20e or 20f variant, and then using the patched Magisk boot_a method), how will I then be able to acquire root again - when I re-update (via KDZ), to A11, i.e. to variant V30a-IND-XX..?

Thank you in advance! : )
[LG G8X ThinQ Guides, News, & Discussion] foenicxxx:
In simple terms, as and when you update the Stock ROM, the root goes off. Whichever android version you want to stay along with root, extract the boot image of that version (or if you have the Magisk patched boot image of the same android version, make use of the same) and patch with Magisk and flash the same via QFIL. And once BL is unlocked, it remains unlocked until you revert back. Locking the BL is a risky though.
[LG G8X ThinQ Guides, News, & Discussion] Ronith128:
You reboot to edl mode, backup boot_a (using Partition Manager) launch Magisk manager, click install ( something like that ), use patch boot image option, selected the backed-up boot_a. Copy the Magisk patched boot image (in your phone's download folder) to pc. Boot back to edl mode, flash patched image using load image option. Done 👍

[LG G8X ThinQ Guides, News, & Discussion] zdanee:
I think as long as you can go back to Android 9 there should be no issues, it's supposed to work the same as with Android 10 and 11: unlock the bootloader, go back to Android 9 to fix FP/audio/network then upgrade to your desired Android version (12) via KDZ, and use Magisk.

Able to support the fastest available charging spec (25W?)

Rubber cable

Hi all,

I have a few themes in this thread with a few features shared. These include:

- Google Feed added to Home​

- Translucent volume bar (except for Full Black variants)​

- Circle and Square icons available in Icon Shapes​

- WiFi Icon changed (except for Vivid Google Feed)​

- Matching Icon Badges in Home Screen (except for Vivid Google Feed).​

To summarize the themes available:

- Vivid Green: Applies the Velvet Green accent (both night and dark)​

- Vivid Teal: Applies a dark teal accent​

- Vivid Google Feed: Doesn't change the accent (so stays Blue for most users) but adds the features from the other themes.​

- Full Black varients: For both Vivid Green and Vivid Teal, there is a Full Black variant which sets OLED Black in a number of UI elements as well as YouTube.​

Vivid Teal is my personal favorite (although Vivid Green looks great with Dark mode). In addition, for those NOT using the official Velvet UI update (but have installed the Accent Color change apk's), using the Vivid Green theme allows the perfect use of the Accent Colors menu since Green becomes the default accent.

NOTE: Since these themes are not uploaded to the Play Store, you will need to install using a File Manager (or app other than the default Downloads app). Thank Google for that :(. Also, if switching between a theme and it's Full Black variant, make sure to uninstall first or it may not work as intended.

Let me know if anyone has any issues and enjoy!

audietron25

Edit: Added "Vivid Green (Full Black)". Pay attention to install instructions as it won't work if "Vivid Green" themes are "updated" between variations.​

​

Edit 2: Changed Youtube background to full black (when using the Full Black variant)​

​

Edit 3: Inadvertently activated Velvet switcher on some devices (which is buggy). Fixed​

​

Edit 4: Changed Wi-Fi icons​

​

Edit 5: Changed Vivid Google Feed to not change volume bar (use Vivid Volume Bar if desired) and also changed notification dots to match the regular blue accent​

​

Edit 6: Removed pop-up modification (applied to old volume bar) from Vivid Google Feed. If desired, install the regular version of Vivid Volume Bar​

​

Edit 7: Added V2 variants. Provides the option for both Google Feed and Smart Bulletin in Home Settings. Have also included a V2 variant to disable Suggested Apps (bottom row of apps in the recents screen) for devices which don't have the option. ​

​

Edit: Mixed up some files, fixed the black notifications (on "Vivid Teal" only).​

​

Edit 2: Added the accent to the same apps as Vivid Green (Gallery, Music, QMemo and File Manager)​
