G7 ThinQ G710EM Magisk, TWRP, No Force Encryption - LG G7 ThinQ Guides, News, & Discussion

Hi, today I experienced unexpected update to Android 10 even I had turned off auto updates and I bricked my phone trying to roll back. So while trying to revive my phone I tested few things and found a way to sort it all out.
Now my phone has TWRP on RAMDISK and no problems with Force Encryption. I didn't tested backup and restore yet so feel free to post results in comments.
1. Install stock ROM, In my case it was 20k, let it fully boot after flash
2. Flash patched boot (for example 20k patched with Magisk 21.1) and boot system to check if you have root:
a. "fastboot flash boot_a magisk_patched.img"
b. "fastboot flash boot_b magisk_patched.img"
3. Boot TWRP G710EM "fastboot boot TWRP_G710EM.img"
4. FORMAT DATA (option where you gonna have to type "YES"), reboot but be careful DO NOT LET SYSTEM BOOT, so keep holding Vol- button while connected to PC and boot TWRP
5. Flash Disable_Dm-Verity_ForceEncrypt_11.02.2020.zip, reboot and once again boot TWRP
6. In Advanced, Flash TWRP to RAMDISK, choose TWRP_G710EM.img and wait until end
7. Reboot. Your phone probably reboots to recovery so in Advanced, Repair Recovery Bootloop
8. Flashing TWRP to RAMDISK can damage Magisk so flash latest zip through TWRP.
9. Done.

Unable to flash anything other than oos

I know, there've been plenty of "please help, I can't flash xx" threads. If there's a duplicate out there, please point me towards it.
I've been trying to get havoc or omni on my phone recently for fun but have had no luck. I've tried multiple different ways, maybe someone can tell me what I'm doing wrong or if there is actually something wrong with my device.
Method 1:
-Use the Oneplus Recovery tool to get a fresh start
-allow OOS to update itself to 9.0.3
-unlock bootloader
-boot twrp-3.2.3-x_blu_spark_v9.91_op6
-flash havoc (for example), flash twrp right after
-reboot to recovery (using button in twrp)
->this results in the phone restarting, shows bootloader unlocked screen, and then goes to black screen/white LED
Method 2:
-bootloader unlocked
-extract 9.0.3 full rom, use flash-all.bat
-fastboot set_active other
-flash-all.bat again (to get the other slot)
-boot twrp-3.2.3-x_blu_spark_v9.91_op6
-flash havoc (for example), flash twrp right after
-reboot to recovery (using button in twrp)
->this results in the phone restarting, shows bootloader unlocked screen, and then goes to black screen/white LED
After this black screen/white led issue, I can get into fastboot but I can't boot the twrp image.
I'm at wits end... I really have no clue what to do. Any ideas? I'm open to try any suggestions.
I should note, when I get 9.0.3 on there, either from method 1 or 2 it's possible to boot and use it.
Try these steps:
(Make sure You have unlocked BL)
Fastboot boot twrp_blue_spark.img
Now go to wipe and choose format data, type yes.
Copy this: OxygenOS 9.0.3 OTA.zip
To Your internal storage.
Now flash it.
Now go to reboot in TWRP and choose reboot bootloader.
Now fastboot boot twrp.img again.
Flash OxygenOS OTA zip again.
Now go to reboot in TWRP, choose reboot bootloader.
Fastboot boot twrp.img again.
Copy latest Havoc OS 2.1 to Your internal storage.
Flash it.
Reboot without flashing anything else.
Should work now:fingers-crossed:
Like 99% you didn't read the "how to" oos needs to be flashed on both slot a and B from twrp rather than fastboot

TWRP on OB 1

Anyone know how to flash or boot TWRP on that Android 10 OB 1. I tried booting with fastboot and it just sits on the fastboot mode screen and flashing it just continuously kicks me back to the bootloader.
I'm not on OB1, but from what I understand the command to boot TWRP doesn't work yet. And you can't flash TWRP in fastboot (can only flash it in TWRP or Magisk). Depending on what TWRP file/fastboot command, you might not even be flashing it to the right partition!
I believe the sequence is:
1) Install Magisk Manager
2) Fastboot flash patched boot image
3) Reboot, open Magisk Manager
4) Flash TWRP installer zip, like it is a Magisk module.

Any help for OP6 stuck on "Boot Loader is unlocked" warning page ?

Hi everybody,
I tried to update my OOS to Android Q while keeping magisk, there was probably a module not compatible that I forgot to remove before and I could not access the interface after rebooting.
Trying to restore the stock boot.img with fastboot, now I am stuck on the "Boot Loader is unlocked" warning page and the phone refuses to boot.
I tried to wipe everything using fastboot -w but still can't boot normally, if anyone can help me solve this please, I would be grateful.
Regards.
Try flashing the unofficial TWRP for Q from here
You can follow that guide but don't install Magisk, then after successful boot, try flashing Magisk uninstaller in TWRP.
Can try flashing android 10 boot.img from #2 link.
this happened to me. It was because I had the usb pluged. If you take the usb out it will boot. Or at least mine worked that way.
What I did was completely restoring the device by flashing a fastboot ROM then updating to Q again. SO I've lost all my data.
Do you know any way I can root android Q actually ?

If you have access to fastboot then you can flash twrp and do below steps exactly else you will stuck at bootloader warning message
Reboot to fastboot mode. Flash TWRP img using the following command--> Oneplus blocked fastboot boot command
Code:
fastboot flash boot twrp-******.img
From fastboot mode, reboot directly to recovery mode. Now you have a working TWRP. (If you already have Magisk earlier, flash Magisk uninstaller now before proceeding to the next steps)
In TWRP, flash the stock boot image in boot partition. Don't reboot .
Flash TWRP installer zip then reboot to recovery. You now have a fully working TWRP in OOS 10. . Don't reboot .
Flash Magisk v20.1. Reboot to system.

Unable to flash TWRP. Lost Recovery, OS and only have unlocked bootloader.

Hi,
I was on Oxygen OS 10.0.0. Rooted with twrp-3.3.1-4-enchilada and magisk 20.1. (I had used this guide to do it. https://forum.xda-developers.com/oneplus-6/how-to/how-to-flash-twrp-magisk-android-10-t3988213) Today I downloaded the zip for 10.0.1 from the Oxygen Updater app and tried to flash it like I have done for OOS 9 in the past as usual. I went to recovery (I did not backup), I just wiped my data (not internal storage), cache and system. After that I tried to install the new zip but I got an error. It just said error unable to install. Didn't mention why. I tried flashing the older OOS 10 zip and got the same error.
So I thought I will try flashing on the other slot. I was on slot B. I switched to slot A and got the same error.
So I thought I will try to sideload. When I tried that I got the same error. So I thought I will try to reflash the twrp img itself. I went to fastboot mode and tried runnning this command
fastboot boot twrp-3.3.1-14-enchilada-Q-mauronofrio.img
It showed me this error
Sending 'boot.img' (65536 KB) OKAY [ 1.609s]
Booting FAILED (remote: 'unknown command')
fastboot: error: Command failed
Now I don't have any recovery at all. I have just the unlocked bootloader and no OS nor recovery. What can I do to flash TWRP again and install either OOS 10.0.1 zip or 10.0.0 zip? Any help will be great.
Thanks

So basically what happened there is TWRP doesn't boot with the oxygenos 10 bootloader. You will need to use the MSM download tool to unbrick your device.

But how is that? I was on stable OOS 10 before rooting following this link https://forum.xda-developers.com/oneplus-6/how-to/how-to-flash-twrp-magisk-android-10-t3988213. As per this, the first step is to flash twrp and that image did flash back when I did it. Any idea why it doesn't work now?
Also, do you have any links for the MSM download tool and any guide if there is?

The problem isn't TWRP it's the bootloader. That's all I know. And for the MSM download tool. See attached link below.

Do not boot the twrp from fastboot it won't work

Fastboot flash boot twrp.img
Then reboot the device to twrp it will boot to trwp and then flash the new a10 zip and immediately afterwards flash the twrp zip

This doesn't work. It flashes successfully but when I select Reboot Recovery and press the power button, it boots back to the bootloader.
Maybe wrong twrp img
Try the older 3.3.1-12 twrp.img and then try
Also try the following as well
Fastboot flash boot_a twrp.img
Fastboot flash boot_b twrp.img
And try just reboot not reboot to recovery

Thanks so much for that! I have been able to recover the phone using MSM download tool. Now will update to 10 using the phones OTA.
However, I have one question, if I update to OOS 10.0.1, do you think this original post on rooting OOS 10, will work for it? https://forum.xda-developers.com/oneplus-6/how-to/how-to-flash-twrp-magisk-android-10-t3988213 Or do you suggest to not root and wait?

Put the TWRP zip and stock boot img on phone (a TWRP img is not a TWRP zip)
Remove Magisk modules first to avoid issues (in TWRP if you cannot boot to system. https://forum.xda-developers.com/showpost.php?p=72542167&postcount=242)
Update through local update to 10.3.2 is what I prefer to do. Then I do the following.
Reboot to let phone finish whatever. reboot into bootloader.
1. Fastboot TWRP img - fastboot flash boot twrp-3.3.1-18-enchilada-Q-mauronofrio.img - ( https://sourceforge.net/projects/ma...3.3.1-18-enchilada-Q-mauronofrio.img/download )
2. Use volume up to recovery and power button to boot to recovery
3. Flash 10.3.2 stock boot img while in TWRP (or current ROM stock boot img).
4. Flash TWRP zip while in TWRP (https://sourceforge.net/projects/ma...-enchilada-installer-mauronofrio.zip/download ) or Blu zip (https://github.com/engstk/android_device_oneplus_enchilada/releases)
5. Reboot to recovery
6. Flash Magisk 20.3 while in TWRP
(Flash a Q kernel if you want one other than stock)
7. Reboot system
You are now rooted

I had similar situation last evening.
I made the mistake of having a factory reset on rooted 9.0.8 and then trying to flash the 10.0.1
I got the same error, so I had to connect my mobile to my laptop, fastboot to the newest TWRP, flash the TWRP, flash the 9.0.9, flash the 10.0.1, flash magisk 20.x and then everything was working.

This worked for me.. Finally. PS - I did in a slightly different order. I installed twrp first, booted into twrp, made sure I was in slot A. If I wasnt, I rebooted to recovery. If I still wasnt I set slot to A manually then rebooted to recovery again. Flashed the stock boot img you linked to boot, then rebooted to recovery slot b (same process I did to get to slot a) then flashed the stock boot img to boot again THEN finally installed magisk. Booted to system, where it hanged a bit, rebooted before getting into android, but booted in just fine after that..
For some reason if you don't flash stock img to slot A (and maybe slot B too, I did this for good measure) before installing magisk everything dies a horrible death and breaks, which can't even be recovered from /boot /system backups..
EDIT: Tried to reboot into recovery, which reverted back to stock for some reason after doing the above steps. So I proceeded to install the bluspark recovery, rebooted into recovery, made sure I was in slot b, made a back up of the boot image, then flashed bluspark kernel. Got stuck at the unlocked bootloader screen. Rebooted into recovery, restored my /boot back. Still stuck when I try to boot into system. Fixed it by booting back into recovery in slot A flashing stock boot img, then into slot b stock boot, then magisk, but also installed bluspark kernel here because I had a feeling I would lose twrp from flashing to stock boot img, and that the issue was caused by twrp (both twrp-3.3.1-16-enchilada-installer-mauronofrio and twrp-3.3.1-x_blu_spark_v9.108_op6 have this issue). Guess what? Turns out I was right. Having twrp breaks everything after you install magisk, so you need to flash the stock boot img before flashing magisk for some reason.. and cant install twrp again unless you dont mind bricking your phone.
EDIT2: F2FS works, just boot into recovery via fastboot (this should be slot b), change /data to f2fs, boot back into fastboot then into recovery again by fastboot (slot b again), flash stock boot img > magisk > bluspark kernel > f2fs_fstab.zip > f2fs_optimize.zip > factory reset/wipe (from twrp before rebooting), done just reboot into system. You of course lose twrp because magisk doesnt like twrp on oos 10.x for some reason, and will need to set everything up again to cause of the wipe. If you dont factory reset/wipe from twrp before booting into system your system will crash and reboot every time you boot into android, then have to do all the steps I listed again.
EDIT3: Never mind, I was wrong, f2fs makes almost all your apps and storage unusable. Not sure if it's cause of the rom (OOS10.3.0) or because we have to flash stock boot.img and get rid of twrp before booting into system. Either way, f2fs has never really been stable or fun to get working so better to stick to ext4.. that few percent performance boost isnt worth it.
EDIT4: This is my last update. After experimenting with different things, bricking my phone, restoring it via fastboot rom, many many times, I've verified the simplest and cleanest way to install magisk.. Do note you wont be able to keep twrp.
Method A - If you already have twrp
Boot recovery into slot a, flash your rom's stock boot.img, then boot into your recovery in slot b (dont boot into slot a recovery because slot a wont have twrp anymore), flash your rom's stock boot.img, magisk and (optional) your kernel of choice (or not) in that order, then you can boot boot into system. That's it.
Method B - If you don't have twrp
Boot into fastboot, and from your cmd/terminal run fastboot flash boot yourtwrp.img (I suggest Mauronofrio's twrp-3.3.1-16-enchilada-Q-mauronofrio.img or newer). Use your volume buttons to select boot into recovery. Make sure your active slot is B, (if it isnt, install twrp (bluspark and Mauronofrio's twrp both work great) by zip, then follow the steps above in method A). Once you've verified you're in slot B flash your rom's stock boot.img, magisk and (optional) your kernel of choice (or not) in that order, then you can boot into system. That's it.
Maybe @mauronofrio or @eng.stk can verify why magisk or twrp bricks the system when you install them together on OOS 10.

@mauronofrio wrote the following in his TWRP thread a while ago:
So little update, after some tests i'm sure there is a compatibility problem between twrp and magisk, i was able to get only one of them, so actually i don't know how to proceed, i need to understand if it is a twrp problem or a magisk problem, TWRP is in stand-by for now.
There are not problems on Android Pie, if you need of the twrp on android Q just flash in boot partition the Q .img (fastboot flash boot twrp.img) and then reboot from fastboot in recovery. Before publishing the twrp I had not tested magisk and twrp together.
On Android 10 use only magisk 19.4

Basically worked for me, too, with 2 exceptions:
- this tool to remove magisk modules etc. wouldn't be flashed, always ended in an unnamed error; probably the cause for some other problems?
- flashing boot.img (V 10.3.4 from this thread) didn't work for me, I always ended up in twrp's splash screen
- got it solved by dirty flashing the full V 10.3.4 ROM (again from the above thread)
Many thanks once again!

Installing custom ROM (Havoc) from scratch

I am going to give it one more go, before I go mad
On the OnePlus 7Pro.
Dirty flash = without wiping anything?
Clean flash = with wiping, but what?
Going to go back to a full stock mode: https://forum.xda-developers.com/oneplus-7-pro/how-to/op7pro-collection-unbrick-tools-t3956595
Then the following steps;
- Unlock bootloader.
- Get the latest version of havoc: https://sourceforge.net/projects/havoc-os/files/guacamole/
- Get Gapps
- Get TWRP
- Get Magisk
- Reboot and use adb to flash twrp.img
- wipe what? Some variations I have come across, so just asking.
- Flash OOS (some say, but which version).
- Reboot to recovery, or flash custom ROM and TWRP.zip?
- flash custom ROM and TWRP on other slot without wiping anything?
- Reboot to recovery.
- Flash Gapps and Magisk (on slot it is on after last reboot, or doesn't it matter?)
- Reboot system.
Follow these steps. they always worked for me.
1. flash twrp.img using adb
2. sideload twrp using adb sideload
3. reboot recovery
4. format data(one where you type YES)
5. reboot recovery
6. flash oos & twrp
7. reboot recovery
8. flash oos and twrp
9. reboot recovery
10. format data
11. reboot recovery
12. flash rom and twrp
13. reboot recovery
14. flash gapps(if necessary)
15. flash magisk(do remember that some roms require first boot before magisk is flashed)
16. dlash dm verity(if you want to stay decrypted).
17. reboot system

Going to try this later, after being out of the game for a while this new "A/B" stuff is just totally defeating me. I've had to restore the phone with that M2M program, or whatever it is called, like 4 times. Ugh. Really miss the old days.
Do step 4 again(format data) if you are still getting stuck on startup or a bootloop, then reboot. That is what I had to do with my Havoc install to get the ROM to boot.

Why are you using adb twice to install twrp on some nonsense that's unnecessary. All your is open cmd in the folder where you have twrp.img or whatever you named it boot to fastboot
fastboot boot nameoffile.img
Flash twrp installer after it boots and you're done.
And before you try to say that commands doesn't work like everyone I'm going cut you off and let you know that it does no problem cause i always use it. You don't need sideload or flash anything with adb. One simple fastboot command will do it.

Thanks for the reply.
I have a few questions, see above in the quote.
Besides that, when I come from stock, do I need to flash the OOS twice on both slots, and if so, why is that?

Same here
With you guys on the "wow this has become a confusing process" boat.
The thing that gets me is with 100% of tuts, they say format data and then say format data again later when I think they mean wipe data the second time. Am I right?
The process even seems more straight forward following the dual boot twrp tutorial.
I don't have a need to update my custom rom yet so I just would like a clear understanding.
Before someone says "well you've already done it" I fluked it somehow. Lol

10. To clarify, yes you have to format(where you type yes)
As far as sideload is concerned, I followed it from a guide written by some dev. But it is not necessary. You may skip it
If coming from stock, you may skip those steps. You just have to ensure that both slots have oos

I tried the same steps for my onePlus 7 but post flashing oos and twrp and all the steps at step 12 while i try flashing custom rom i.e Pixel experience in my case i get the belowmessage
"Flashing A/B zip to inactive slot B .
To flash additional zips, please reboot recovery to switch to the uploaded slot.
Error installing zip file '/sdcard/PixelExperience_gucamoleb-11.0-20210217-1706-BETA-OFFICIAL.zip'
updating partition details......
...done'"
But while doing step 6 i.e flash oos and twrp despite the below message
"Flashing A/B zip to inactive slot B .
To flash additional zips, please reboot recovery to switch to the uploaded slot"
It gets flashed without issues.
Just to let u know my phone got bricked so i installed the official firmware using the below command.
fastboot -w update images.zip
Any help on this will be appreciated as i m kinda stuck with the stock rom.
