[Q] 5.1.1 stock update: Re-root and Unencrypt Q's

Many of you have heard by now that 5.1.1 is out, and we should receive an update soon on our stock rom Nexus 6. I just bought a Nexus 6 64gb, XT1103, and it is running the stock rom, rooted, and un-encrypted. I'm wondering if we'll lose root and un-encrypt if we take the update, and loose data if we re-unencrypt. What have your experiences been on the stock rom 5.1 update?

While the update will download, it will not install with root and an unencrypted kernel.
IF you want to take the OTA, then you will need to fastboot flash the boot.img and system.img from the factory image. Boot.img will encrypt your kernel, but you will not loose data (but you will have to factory reset, again, if you want to unencrypt, which will wipe data). Flashing the system.img will remove root and flash stock recovery.

so unroot and encypted will do the trick? what about the bootloader, will it work with unlocked or should it be relocked too?

5.1.1 is NOT officially out for the nexus 6. it is in aosp though. thats two differing things. stock is on 5.1.

The OTA package only looks at system.img and boot.img. Of course you need stock recovery to install it. And the "unroot" option inside SuperSU is insufficient. It leaves some traces around that will prevent the OTA from loading. Flash the stock system.img.
And afterwards, when unencrypting, you'll have to fastboot format userdata. Which will wipe your SDcard again.

Bootloader status has no effect on the OTA.

I have rooted, but encrypted 5.1, and got OTA5 5.1.1, I am on custom recovery,
should I flash stock recovery before flashing? plus, after installing, I will need to regain root access right? my data/apps will stay intact right?

As it says above, you cannot FLASH the update if you are rooted, even with a stock recovery.
You will have to flash the system.img and boot.img of the Stock factory image. IF the full factory image of the version you want is available here: https://developers.google.com/android/nexus/images
...download it, extract the system and boot.img and fastboot flash them. Job done. If the version you need is only available in an OTA file, you'll need to flash the system and boot of the expected version (i.e. the one you're on now) AND flash the recovery to accept the OTA

I am using a custom recovery, on a rooted but STOCK 5.1, and I already got OTA, I downloaded it as well, but needed to make sure before upgrading, that it doesn't cause data lose if I move to stock recovery, and want to regain root after flashing 5.1.1,
anyway, i flashed stock recovery, then proceeded with the update, it tried flashing but showed "error" at the android screen, so, I don't whats missing, as I was using stock 5.1, just unlocked it, rooted it, and flashed customer recovery,

When I said receive, I meant flash. You cannot FLASH the update if you are rooted. Period. Read my post again but substitute the word receive for flash.

got it, but still looking for the answer, will I loose data after flashing system.img? or while regaining root after 5.1.1 update?

No. Only factory reset or unlocking the bootloader loses data. System.img is the rom, flashing to /system. Boot.img is the kernel, flashing to /boot. if you flash these separately, userdata.img is not flashed to /data, so your /data partition remains in tact.
root doesn't touch /data either. Just /system

Yeahhh I get that now. It's got to verify that what's already there matches what it's supposed to be updating.
I'm looking here because I'm on Fi now, and there are more implications there than I realized before. Not that those matter too much, I do want stock. Just trying to see how I can stay current, be rooted, and not break Fi. Thankfully it's a Nexus device so it's not throwing up insane device restrictions blocking root access.
I want to be able to update system and boot, as they come available, with a recovery like TWRP or CWM. Then reapply SuperSU flash after that. What I'm not sure of is whether I can even do that. I'm fuzzy on the whole " encrypted device" thing. Does that apply to the images at https://developers.google.com/android/nexus/images#shamu
Would I be hosed if I took the system and boot images and flash those to update from one version to the next?

You absolutely can, it's just that if you wish to decrypt, you'll have to format data. I've had this device, since launch and I'm still encrypted. Not an issue for me. But you can just flash, individually, everything but userdata and keep your data intact, each time a new image becomes available. Then just flash TWRP and then SuoerSu from TWRP. If you've unencrypted, OTA won't flash. You can always update manually.

edit - this was a duplicate. i can't delete it.

Oohhh, wait, so flash from fastboot, except flash SuperSU from TWRP? (update.zip style?) Is only the data partition encrypted then? If that's the case why are folks decrypting? Unlocking the bootloader requires it, but what is that required for?
And thank you loads BTW! I'm so far behind! I'm coming off 3 years of rooted, stable SGS3 stock, last updated to 4.1.2. There were no further stock updates that I wanted, (too many bugs) and everything was working so I left well enough alone.
(I probably would have messed about with CM and other roms, if I had not initially bricked the thing trying to put TWRP on... and had to send it for somebody to JTAG reprogram it. Thought about it several times, but never wanted to chance it again.)
Thanks again!

[Q] 5.1.1 OTA while rooted?

I've been receiving the prompt to update my N6 to 5.1.1 for the past few days, but whenever I attempt to install it, it says it's rebooting and does nothing. Is this because I'm rooted? Besides being rooted, there's no modifications to the system (well, except for Franco Kernel and MCR I suppose...). Is it even possible to update this way? Any help would be much appreciated. Thanks!

Well that's a bummer! Thanks for the link. It looks like sideloading will still work, is that correct? If so, is it possible to sideload an update without wiping my data or factory resetting?

If your bootloader is unlocked, just do this:
Download the factory image for the new build you want.
Extract twice to end up with the bootloader, radio, boot, system, recovery, userdata, and cache images.
Flash each image individually with fastboot except for userdata.
You will be updated and won't lose data. Then, just flash TWRP again and then from TWRP, flash the superSU zip. You will be stock rooted, with TWRP recovery. All your data will remain.
If you try to flash official OTA via sideload, it will still fail because of root and custom recovery.

[Help][NOOB] Want to do fresh install of latest official OOS and stock recovery

Hello,
I have Oneplus 3 A3000 running on OOS 4.0.1 (Android 7.0). I also have official OP3 twrp recovery version 3.0.3-0 installed and root was done using supersu free v2.82.. It also has dm verity prompt which comes up during boot time because it is oem unlocked.
I want to know exact procedure to go to complete stock rom + stock recovery along with links to download stock recovery and rom. I saw different versions of stock recovery for different OOS. I don't care about device data as everything is on cloud and nothing on is on device. App list also I can get from google account history. Only thing I care is not to corrupt any system partitions. I also saw few posts that go into boot loop if incorrectly unrooted. I would not want that either.
Your help is greatly appreciated. Virtual beer for you ???. I am software engineer so even though I am noob in terms of hacking my android, I can follow the instructions properly.
Thanks again.

You can flash official OOS Rom and just use TWRP, you can try using the current recovery you have. Allow it to boot after if it allows you then do not go back to TWRP, allow it to boot to its system and then normally it will just override TWRP with OOS stock recovery.

flash stock oos thats it.. you may leave the bootloader unlocked. better that way..

Sorry but I am still not sure about exact process. Here are my noob queries:
1. Should I update twrp to latest version before proceding? If so which one? currently it is 3.0.3-0. I remember running into encryption issue due to unsupported twrp when I did this last time.
2. Should I use wipe option to wipe anything before I update OOS? I want to do clean install. If so, what should I be wiping out of dalvik/system/data/internal storage/cache/usb otg?
3. To update, I should copy full ota zip on internal memory -> go to recovery -> install -> select zip file -> swipe to flash. Is that correct?
4. After that if I boot into recovery -> I will keep twrp and if I let it boot, it will replace twrp with stock recovery right?
5. Let say, I let it boot n install stock recovery, will I have dm-verity during next boot?
6. Will my superSU root be gone or still be there? If it is still there should I do complete unroot before starting this process?
7. If it is not gone, is it ok to do complete unroot after stock oos + recovery is installed?
8. I saw a dm-verity patch zip which can be used to patch dm-verity in bootloader mode if I do "fastboot oem disable_dm_verity and fastboot oem enable_dm_verity". Does it suppress the issue or it resolves it gracefully?
Thanks for the patience and help in answering the queries advance.

1. Try the first the current TWRP that you have. If it work, then just reboot it on to the system and TWRP will be overwritten by Stock OOS recovery.
2. Wipe dalvik/system/data/cache ..
3. YES , if im not mistaken.
4. answered on question 1.
5. most probably. Try flashing a certain firmware (not sure which one would work) . This is what I did before. But cant be sure.
6. It will be gone.
7. gone.
8. You can try.

I will tell you what I do.
Flash the latest official TWRP which is 3.1.1-2
If you want a totally clean install, boot into recovery and wipe system data including internal storage, dalvik and cache.
Then without rebooting, push the ROM downloaded from the OnePlus site to the phone. Select the ROM in recovery and swipe to flash.
Otherwise you can copy the ROM to the phone, boot into recovery, wipe system, data, dalvik and cache and then in recovery, flash the ROM.
Wipe dalvik and cache and reboot into system.
Your root will be gone and along with it TWRP. You will be on stock ROM with stock recovery.
Leave the bootloader unlocked. If necessary, it can be locked at any time.
Most likely you will not get the dm verity error. If you do, simply flash the zip given in post #215 in siankatabg's thread on dm verity. It will merely remove the message as all such methods do.
Enjoy

Hi sorry I was afk for couple of weeks. So I started following this procedure. Very strangely, after I did a reboot post stock OOS (1.4gb zip) flash, twrp said no os installed, you are sure you want to reboot? I wasn't sure so I just said yes. Then I also so dm-verity coming back which was not the case when I started as I had disabled it using "fastboot enable_dm_verity" command.
Now, its been more than five minutes and my phone is stuck on the boot animation forever. (red dot in middle and two while dots rotating).
I am not sure what happened. Can someone please help me ?

Awesome. I am still getting safety net failure even after locking bootloader lock. Any ideas? It fails on CTS profile match. I even did factory reset. Only thing I can think of is the "dm verity" which is back for some reason even though I am on complete stock rom+recovery with no root or unlocked bootloader.
Any way to remove it from stock recovery?

There is a zip floating around XDA which I am not able to locate immediately. It may be on siankatabg's thread on dm verity. Simply flash it.
There is also another method I read about where you flash the 4.0.2 firmware, use the enable verity command on adb, boot the phone and then flash the current firmware.
Both methods are mentioned here in XDA. Search for it.
EDIT: One of them here: https://forum.xda-developers.com/showpost.php?p=72273041&postcount=215
See also the OP of the same thread for the other method.

i remember having the dm verity but i forgot what i did to make it disappear.. after that time ive been running OOS rooted with twrp until i decided to go back to stock locked

So, I stopped doing anything as I got busy with my life. Here comes the 4.1.7 OTA and my DM verity was gone. So, it seems like if you go to stock and if still dm verity exists, try to do ota update or go to one ota back for flashing.

This ROM based on H87220xxxx.kdz then extracted and repacked with autoprime's zip based on this thread.
Also, thanks for runningnak3d for TWRP install method. This ROM is ARB01 which is safe if you want revert to 11g.
Installation :
Modullar Installation
You should install at least bootloader, modem, and system in order to boot properly.
Install xxxOreo.zip using TWRP don't reboot
Press back button and Install Magisk (It's mandatory if you want root and twrp retained)
DONE and Reboot
[*]In most case, you'll lost your /data due to data encryption. so backup first
[*]This build's ONLY for T-Mobile US LG G6
[*]If you decided to downgrade, make it sure that firmware is ARB01 (11g or later)
Download :
As requested by many people I've uploaded new update within 4 modules (Bootloader, Laf, Modem, and System).
You can download here: H87220g (latest)
LGH87220F
LGH87220D
LGH87220A
Recommended TWRP/Orangefox Recovery
my G6 seems broken, it has no display but it still ringing when I call it. probably LCD issue. Basically, I can't test any future update with this phone. I've planned to buy v30 soon and try to repair my g6 by myself. Any info or some suggestions will be appreciated
Have a nice day,

OK -- So I am going to install that later today...but just to be clear (and hopefully this helps others)...if you have been flashing other ROM, you should have...
1) H870 TWRP in laf, accessible for emergencies via holding up button and plugging phone into computer.
2) H872 Unofficial TWRP in recovery...
So, to flash this, using H872 recovery/TWRP:
1) TWRP backup whatever you want to keep.
2) Wipe all normal stuff
3) Flash this and magisk, assuming you want to root anyway.
4) Using TWRP File manager, delete /system/recovery_rom_boot.p so that if something goes wrong, you don't have to reflash H872 TWRP into recovery using laf.
Boot, and you should have the stock 8.x rooted?
In my case, I also a going to try and install stock GApps to replace LG/TMobile stuff...I'll post about my success on that later...

You'll get download mode back after flashing this zip anyway (stock laf). in case something bad happens, you should not worry much. though, i've never use custom rom in this phone before. so, extra precaution will be good for you.:good:

Which is the correct way to do it in my opinion. Once you TWRP installed in Recovery, having it stay on LAF is dangerous as far I'm concerned. In theory TWRP should be able to keep you from needing to ever restore back to stock, but it has been known to fail sometimes. Leaving with no way of using LG UP or any other flasher outside of sending it into LG (unless firehose files get leaked).

yep, flashing back original laf will save you in the future mistakes.

By "Stock" do you mean LG's bloatware stuffed "stock" or do you mean "Vanilla Android" stock?

OK -- So I am going to install that later today...but just to be clear (and hopefully this helps others)...if you have been flashing other ROM, you should have...
1) H870 TWRP in laf, accessible for emergencies via holding up button and plugging phone into computer.
2) H872 Unofficial TWRP in recovery...
So, to flash this, using H872 recovery/TWRP:
1) TWRP backup whatever you want to keep.
2) Wipe all normal stuff
3) Flash this and magisk, assuming you want to root anyway.
4) Using TWRP File manager, delete /system/recovery_rom_boot.p so that if something goes wrong, you don't have to reflash H872 TWRP into recovery using laf.
Boot, and you should have the stock 8.x rooted?
In my case, I also a going to try and install stock GApps to replace LG/TMobile stuff...I'll post about my success on that later...

BTW -- I did this method, got laf back to what it should be, rooted the H872 Oreo, installed GApps, and have a pretty good setup with Volte/WiFI calling, Goodle Dialer and Messages (with web message support), stock camera, etc -- kinda best of all worlds.
The only issue, as noted in another thread, is that TWRP can no longer mount data -- meaning you gotta jump through some hoops to back it up...so hopefully this get fixed.
For those that are not aware, with TWRP still in recovery, you can boot to this following the factory reset options for the phone, but after answer to confirm "Yes" twice, you will boot into recover TWRP, so you can always get back there without a laptop and / or fastboot. If I recall, the key sequence is hold down button, hold power until logo appears, then turn power on and off until factory reset appears...
But TWRP needs to be fixed to access that data partition -- no idea what that is all about.

So twrp rebooted even though I clicked cancel on reboot, magisk not installed. Is there anyway back? I'm totally fine on stock btw if that's the case.

Try to combination buttons for reset, it'll brings you to TWRP again, and install magisk after that. Hope twrp still remains in recovery partition as sometimes they'll be replaced by bootloader. If it doesn't work, you should be able to use LGUP to flash 11g kdz, and try flashing twrp again.

I believe that's possible, all you need's the right dm-verity disabler that works with this phone. In theory, just format (not wipe) your data partition, flash rom, flash dm-verity disabler, and then reboot. Data partition is encrypted by bootloader, I've checked twrp's fstab and all point to the right direction. But still, we've to try this before knowing what's actually possible or not. For now, I utilize LG Mobile Switch to backup my data and it's totally fine.
UPDATE: It doesn't work, dm-verity patches actually only patch boot.img while this phone has aboot, tz, and a lot elf programer

I doubt it is...because mine didn't and there was no /system/recovery_rom_boot.p to delete.
you can try installing a program like Titanium Backup that has the option to reboot into recovery.
Did you get it to the menu asking to factory reset -- if you got that and answered yes both times and did not get into recovery, then it is gone...

if your phone is from T-Mobile, it's b872bk. please check ota update. if you got oreo update then you're in the right path. but if not, then it's more likely that your phone is the 872tn one.

I'm assuming the 2 letters at the end signify the color of the devices (BK = Black and TN = Titanium/Silver). Even though the devices are the same, perhaps there are minute differences in each build? I flashed the 20a zip that was provided by OP, but it changed my splash screen to say G6 ThinQ? The G6 I have is T-Mobile branded Titanium color, but I definitely had the devices before the ThinQ moniker became a thing. I'm going to download the KDZ branded for my 872TN and see what happens when I flash with LGUP.

The G6 ThinQ splash screen came with the oreo update. I think too that bk=black and tn=titanium no diff at the builds.

Your zip save my phone
Keep it up bro ..
Thanks

So I should be able to flash this through twrp like any other zip?
Y'all were talking about deleting deleting things so I wanted to make sure before I did anything.
I'm in agreement with fixing the laf after getting root, and this way looks like it would simplify matters if you got stuck with an issue and didn't want to or didn't have access to a pc.
Thanks

Thx))) I was very much waiting for this.
I'm now at 20a. if I flash the bootloader only, then the fingerprint scanner will work on custom firmwares? Does the custom LAF work?

very welcome. if you flash the bootloader only it will leave whatever laf you have untouched, and yes fingerprint scanner will work with custom ROMs like AOSP Extended.
However, I have not tested running stock 20a with the 11g bootloader. But it doesn't sound like that's what you are wanting to do
*edit*
if you have already flashed a custom Rom and FP doesn't work, simply flashing the 11g bootloader zip will fix it. it is not necessary to reflash the rom
also, not sure why anybody would want to, but 11g bootloader with stock 20a rom will not work. it will hang on the boot logo indefinitely which can be dangerous for your phone. so please make sure you are using a custom Rom or stock 11g with this bootloader

Any way to flash one of these stock images. Rom itself. If you can't get into twrp? Check my post from last night in the root thread and you'll see what I'm on about.
Phone boots but system ui stops which keeps me from getting in. Lost twrp from recovery somehow. All I did was apply a then through substratum and it all went South from there.
Not hounding ya just thought I'd prefer over here and see what you been up to.
When I run step 1 in that root thread I get no hash match and something about with laf or lafbak not being present. Haven't fully fired up the pic too see if I can post the output from that here. (Honestly, was never that good with logs lol)
I'm curious though if flashing your laf (how in the heck it happened is beyond me) if it's possible through adb or lgup would put me back to right.

Do you still have root? if so you can extract the laf.img file from the StockLAF zip and use adb shell to push it to the dev blocks
put the laf.img file on your sdcard and rename it to laf.bin, and run these
adb shell
su
dd if=/sdcard/laf.bin of=/dev/block/bootdevice/by-name/laf
dd if=/sdcard/laf.bin of=/dev/block/bootdevice/by-name/lafbak
that will restore stock laf

Have to have root eh? So I'd need dl mode back to flash the kdz to get root but can't unless the kdz restores laf in the process which if it did this wouldn't be required I'm thinking.
Sorry man just thinking through things.
When y'all are putting in " /by-name/ " it would be h-872 right? Stupid question I know but I've never seen it mentioned straight out anywhere

Yeah you need to restore stock laf another way if you dont have root. Root is needed for ADB shell.
and no, /by-name/ is the actual folder name. I think it's a directory of symlinks, but i might be wrong. Basically it lets you access a partition or mount point by name. in this case the names of the mount points would be laf and lafbak

Thank you for this weaknpc! This is really saving my a*s. Quick question. If I flash the FullStock version, will I have to unlock the bootloader again? I am using the AEX rom (have twrp 3.2.3 on laf and recovery I believe) and just want to go back to the full 11g firmware. If this works I wont even worry about flashing the laf partition (I would only do that for using LGUP+11g kdz).

Glad I could help, man. No, none of these will lock your bootloader. They wont touch your recovery partition either. If for any reason you want to go back to stock recovery let me know, I can pack a zip to flash that from your LAF TWRP if you still have it.

You are most welcome! But important FYI, I discovered an issue in the original FullStock zip that was causing the laf partition to be flashed over with stock. I am posting an update to the project with another handy file for people with TWRP on recovery. If you downloaded FullStock prior to this morning, you will probably want to reboot to recovery and flash it.
Flashing h87211g_TWRPLAF.zip from custom recovery will put TWRP back on your LAF partition.

If I were to downgrade if able to, would that have a chance? I still am getting stuck in fastboot mode unless I'm hooked up to the pic and let lgup do it's thing.
It detects the device, does it's thing, reboots it and gives me a factory reset phone back just no dl mode.
It's not bricked yet lol.

Ok, so the flash did not go exactly as planned, there was some issues getting into recovery. Let me give you a run down of what I did.
1. Boot into twrp recovery using a reboot app (requires root) from a working rom. (This is really the best way I can get into recovery besides using adb) 2. wiped the system/data/cache/dalvik cache partitions. 3. Flashed the FullStock zip. 4. Flashed magisk and it was unsuccessful (it was not able to mount system or vendor partiton I believe).
I did not realize you need to reboot into recovery from twrp recovery, then flash magisk for it to work. I thought it may have flashed anyway. Needless to say I booted into the system and I had no magisk so no root. When trying to boot back into recovery using the hardware buttons, I could not get into recovery. It took me to the factory reset screen. Usually at this point if you select, yes factory reset the device, it would boot into twrp (I think this is some initial mask that lg puts on the recovery partition? ), but this time it was just a orbiting rainbow colored cicle animation. At this point I was saying "oh fu*#!". Then once that animation was over the phone began boot looping. I thought I bricked the phone at this point. Then I tried getting the phone into download mode by holding the volume up and inserting the usb cable. I got the download mode graphic, and then a second later, bam I was back into twrp! Lol. Crazy. I guess twrp was still on laf after flashing FullStock! So, I think that maybe your FullStock zip flashes the stock recovery partition and not the stock laf partition.
Now I was in twrp I was back in business. This time I did the steps correctly and magisk did flash, however I did not format data so now I was getting the encrypted data issue when booting into the system. Then on the third attempt I booted back into twrp using the download mode trick and this time I got it all right. 1. fully format data partition to clear encryption 2. wiped the system/data/cache/dalvik cache partitions. 3. Flashed the fullstock zip. 4. reboot into recovery using the option in twrp 5. Flashed magisk successfully. 6. Reboot into system 7. Phone booted fine, no encryption issue, magisk manager sees magisk is installed and I have root.
So this is where I am now. The phone works fine and I have root. I am afraid to flash that laf zip with twrp becuase if I am correct, there is some specific hash that has to match the device when twrp is on laf. There are steps regarding this for the root method for the H872. Maybe it works on your phone, but I don't want to assume it will work on mine. I would not like to brick this thing, lol. Maybe I don't know what I am talking about...
Also, everything on this rom works great except for bluetooth audio! For some reason bluetooth audio is super super low even at max volume. When I had 11g before, it wasn't like this so I don't know what the heck happened! Through the headphones you get a prompt asking if you want to raise the volume above the limit but nothing like that for bluetooth. Does anyone know how to fix this? (Btw, I thought magisk viper4adroid might solve the issue but it does not work for me with this rom. I tried it and it just crashed system ui after reboot, almost got in a bootloop from it. Luckily I was able to disable the module after another boot)
So, if I can't fix bluetooth volume, I will be running this for a while, then I will flash the stock laf to get real download mode back and do a full kdz flash using lgup so I am truly back to stock. Then I will follow the H872 root process from the ground up, etc.
Either way thanks for this npc. At least I am able to have 11g! Thanks for your hard work. :good:

I'm sorry that you had a little trouble. It actually makes sense that you needed to format data. I will update the instructions to start things off with that step.
The actual, proper procedure, would be to format data, reboot back to recovery, wipe system, data, dalvik and cache and then flash FullStock and Magisk.
I'm glad you still had TWRP on laf. Maybe I was looking at an old updater-script. I do know, however, that I removed the recovery flash from the rom so that never should have been replaced. What I think might have happened with you is the Stock firmware's recovery repair feature. Since Magisk didnt flash correctly and you booted to OS, it would have tried to repair stock recovery.
As for the TWRP LAF zip, it is an exact image of the LAF partition after it was processed by @runningnak3d's root procedure. So there shouldnt be any checksum issues at all. It should be totally safe.
The bluetooth thing is probably the most puzzling to me. I extracted all of the images in these roms directly from the stock KDZ. Your system should be a mirror image of any device flashed with LGUP.
Try flashing the SysBoot ROM on top of what you have now. The file structure in that rom is different. Instead of extracting a system image to your system block (the way fullstock does) it actually flashes all of the individual system directories to their designated blocks. I have a feeling that it may fix your issue.
Thank you very much for the information. If you end up doing anything else let me know how it turns out. If I can help you not have to flash the KDZ then I'll be happy. That was my main goal in creating these packages.

What I think might have happened with you is the Stock firmware's recovery repair feature. Since Magisk didnt flash correctly and you booted to OS, it would have tried to repair stock recovery.
As for the TWRP LAF zip, it is an exact image of the LAF partition after it was processed by @runningnak3d's root procedure. So there shouldnt be any checksum issues at all. It should be totally safe.
The bluetooth thing is probably the most puzzling to me. I extracted all of the images in these roms directly from the stock KDZ. Your system should be a mirror image of any device flashed with LGUP.
Try flashing the SysBoot ROM on top of what you have now. The file structure in that rom is different. Instead of extracting a system image to your system block (the way fullstock does) it actually flashes all of the individual system directories to their designated blocks. I have a feeling that it may fix your issue.
Thank you very much for the information. If you end up doing anything else let me know how it turns out. If I can help you not have to flash the KDZ then I'll be happy. That was my main goal in creating these packages.

Ahh yes this makes sense. Maybe it was a stock recovery repair due to magisk failure as you mentioned? I still don't understand why with these LG phones (ever since the G3 I think), when you boot into recovery using the hardware buttons, it asks if you want to factory reset the device. Then if you say yes, it doesn't reset/format anything, and it boots right into twrp recovery after that. So weird. I can boot directly into recovery just fine from a reboot app or adb from a running system without getting that factory reset screen...
I'm sure your laf zip with twrp works for the reasons you mention. Luckily I don't have to find out since my laf partition is fine and still has twrp!
Regarding bluetooth, I will give the sysboot flash a try and update you with the results. First I want to wait until my backup phone is running again. I bent the sim pins on the backup phone due to those ****ty plastic adapters that catch the pins (an old E980 w/ the larger sim size) so I ordered another sim reader to fix that. I also read in some forums that wiping cache and dalvik cache resolved others bluetooth issues with the G6. I will try that too.
Either way, I will update soon. I am happy to share my notes as I really appreciate the help!

I'm rooted and running an old version of aex. I'm still getting the encryption message anytime I try anything without that rom. These last two posts. When you talk about formatting your saying in twrp correct? Or that forced format you can do with the buttons?
Basic point is I'd like to get rid of that encryption message and it looks like your instructions take place after we achieve root. I'm wondering if I should just kdz to 11g and root from there. Or would just flashing your full stock zip do it? I seem to be the only one having such an issue with it so I'm figuring I'm missing something somewhere that y'all are doing or whatever that's getting by me.

What Encryption message are you talking about? The one in TWRP where it asks you for a Passcode?
So far, I have tried removing dm-verity and force-encryption from both the 11h and 20a kernels, but I have not been successful. The OS always ends up encrypting data. However, after I flash Magisk I no longer get any passcode prompts in TWRP. I am able to backup and restore system and data no problem.
The only thing I have not tried is a rom packed with dm-verity and force-encrypt removed and root built in. That is the next thing on my list once I get a deodexed 11h rom done.

Yes that's the message I get. So your saying not to worry about it for the moment? I only see it regularly on a stock rom when going into recovery not aex.
I just wanted to make sure. With the mess I been going through.
So, I can flash this stock build you have and if I wanted normal download back flash the laf zip and I'll have DL mode on laf, twrp on recovery and everything should Mount correctly and all that?
And if I go to flash something custom FP will work? I know I'm a pain I just want to "know" my setup isn't weird somehow. Probably over thinking it, but I think I'm good, except that when I rooted I was getting that message off & on, on the stock build of 20a. I'm hoping that running this build I can get that worked out. Maybe that deal is a 20a thing? Reading through the root thread it seemed to happen less to people on a lower numbered build and it would stop after the format.
I can make backups Burt I've yet to try to restore one.
