Some experience after upgrading to Oreo (root) - Sony Xperia XZ Guides, News, & Discussion

Hi all,
Not even sure I'm in the right place, still I'd like to share my own experience after upgrading to Oreo last few days. So moderators, if you guys find this irrelevant, or it is in the wrong place, please help me move it accordingly.
I am using XZ F8332. Last few days I decided to say hello to Oreo after some time being patient with the pretty annoying "Upgrade your system" notification. I finally managed to have a fully working Oreo + DRMfix + Magisk + SafetyNet passed and root. Unfortunately good things usually come with bad things too...
At first, I was trying to patch my boot image using ta_poc method. Believe me ta_poc seems to be working on Oreo too, I got all the DRM functionalities working thanks to munjeni & serajr. However, it doesn't seem to be working with both Magisk and SuperSU. I tried all recent versions of those two e.g. Magisk v14, Magisk v14.5 beta, SuperSU v2.79 SR3, SuperSU v2.82 SR5, etc... ALL cause bootloops! I had to come to a conclusion that any methods that patch your modified (with ta_poc) boot image will cause bootloops. There's one thing I didn't try: SuperSU system mode which installs to /system. What's the point of system-less then? But it's up to you to try this.
The above means you are most likely gonna lose root if you go with ta_poc on Oreo. So I had to give ta_poc up and go with DRMfix instead. I got into a few troubles then.
I was initially trying to keep my userdata intact, so I didn't do a full wipe, I actually wiped everything except only my userdata (including data in sdcard). DRMfix didn't fix at all. All I got was only "FIDO_KEYS: Provisioned", the rest was "general error!" and of course DRM functionalities didn't work. I did some search, followed some guides saying about removing these directories: /data/credmgr, /data/drm and /data/mediadrm. There's even a script named "SafetyNet-Cleaning-Tools" also does exactly the same. Perhaps I wasn't that lucky enough. It just didn't work. Until I had to pull all of my data out, do a FULL WIPE including userdata, DRMfix worked then.
Next thing is to get Magisk (or SuperSU) working to have root. I knew recent update of SuperSU causes Xperia devices into bootloops. I also used Magisk on Nougat too. Why not now? So I flashed Magisk v14. Uh oh... I met my old dear friend again, Mr. Bootloops. So Magisk v14 doesn't work on Oreo. But v14.5 beta does. That's how I got it fully working.
Then I pushed my data back to sdcard (including a nandroid of course), did a restore DATA ONLY in TWRP and manually delete the folders mentioned above. After phone started, everything went back. I smiled.
Some existing Magisk modules started to work without any problems. But some other they need busybox. Without any thoughts, I immediately installed osm0sis' busybox installer, the one on Magisk repo. Weirdly it said "Magisk is not activated". I tried other modules, same issue. So only existing modules work, I couldn't install any new modules using Magisk Manager. "Use TWRP then" I thought. I went to TWRP and flashed the busybox installer. My old dear friend came and said "Hi! Bootloops!!" to me again. This time I used Magisk uninstaller to clear magisk files and re-flashed it again. I was able to get back in. I tried YashdSaraf's busybox universal installer. Same issue. Maybe I haven't tested well enough or maybe I went completely wrong way, but looks like busybox isn't working on Oreo? Also, I'm not sure this is the right way to do it, or we have to "clean install" Magisk too? Like uninstall everything first and re-install module by module all over again?
Also, after some Magisk uninstalls and reflashs, suddenly my DRMfix was no longer working. It displayed "general error!" in Service tests -> Security. I tried to fastboot the modified boot image again. Not working. There's no way to get it back except a FULL WIPE. I didn't get it. System-less approach is supposed to have nothing to do with our files. Somehow it does leave some traces, which we need a FULL WIPE to get rid of it? Maybe it isn't just the 3 folders mentioned above, there's maybe more?
Additionally, on Oreo I got some other bad stuffs:
- Adaptive brightness keeps adjusting, going darker and brighter very very quickly. It's no doubt an Oreo's bug.
- Cannot open Titanium Backup. It crashes right after you open it. I tried v8.0 and v8.1. Same issue. Maybe it's because busybox isn't installed?
- I have a feeling battery drains issue comes back. Looks like its consuming more battery than latest Nougat I'm not sure. Haven't got time to do some stats yet.
Last but not least. When I was pulling / pushing data to / from, I noticed that the storage space somehow changed! My phone is 64gb but the second time I got it fully working, it said "storage is 80% full..." and when I opened Settings -> Storage it showed only 21gb! What I did to get it fixed was to run fastboot format userdata. Then I let the phone start normally (without old data), after finishing setup, I turned off and went to TWRP to restore DATA ONLY. Problem solved. I got my storage back. But I have never figured out why. Maybe something wrong with adb pull / push in recovery?
If you've read down this far, I hope my experience could somehow help you avoid encountering the problems that I did.
Me personally I think I will go back to Nougat and stay low for a while. You understand why. Another reason is I also wanna try the "official" xposed for nougat for a little more. rovo89 is freaking awesome. man, he's a legend.

ta poc needs to be rebuild, but munjeni probably dont wanna work in his tool anymore. But serajr´s tool works well so you can root xz oreo with magisk. cheers

Yeah it what I have atm, but I still can't mirror cast to my tv because it not real drm keys

CTS Mistmatch... tried 'everything'. Help me fix?

Hi, my set up was working fine, safety net passed etc.
I'm on the latest 7.1 rom, patched stock kernel (ta_poc etc)
But today I encrypted my device and then flashed the new TWRP we have - https://forum.xda-developers.com/x-compact/development/recovery-twrp-3-1-1-xperia-x-compact-t3640914
I then notice in Magisk that there is a CTS mismatch...
Maybe the cause of the CTS mismatching happened a few days ago, I'm not sure.
Anyway, I want to fix it!
I tried flashing the latest rom via flashtool, I did a factory restore from system settings, I also tried flashtool again + wipe data in flashtool, I tried using the 'old' TWRP.
Each time, I flash Magisk v12, install the magisk manager 4.3.3.
I still get a CTS mismatch.
I have tried toggling magisk hide, then rebooting, toggling core mode, then rebooting, nothing seems to work.
Does anyone have any advice that can help me?
Will anything bad happen if I tick all of the boxes to 'wipe' in flashtool? (apps_log, diag, persist, qnovo, ssd? userdata - (that one's safe I know))
I would really appreciate it.
Thank you.
Ok, some news.
From what I understand, the safety net check is online.
So, it can be updated and improved by Google/Android, to detect our hacks.
I can only assume that whatever state my system was in, was no longer good enough or no longer hidden enough to pass the check.
I flashed the only true custom kernel we have, Genesis kernel (1.05), I didn't patch my TA keys in using ta_poc, I read Magisk v13 has problems with ta_poc.
I simply used the drm_fix version, as long as the features are all there (I read drmfix fixes everything apart from wideside, I don't know what that is...)
I flashed the drmfix version, installed Magisk v13, it is recognized and works! (unlike on my patched stock kernel) -- and my device passes safety check again

Don't you have to use ta_poc and the RootKernel tool together for Magisk to work properly?

Yes I did that, and it was working with magisk v12 but not 13.
https://forum.xda-developers.com/x-compact/how-to/android-pay-safety-net-rooted-unlocked-t3610342
" 4. Tobias tool has to be used to repack the boot image because I found that if PoC image is used directly, phone will reboot unexpectedly after Magisk is installed. "
With genesis kernel I have updated magisk and safety net passes, plus I am using the new trwp we have so my device is encrypted.
I'm very happy

Magisk Systemless root how to OTA update? Help needed!

I'm following the topjohnwu's guide on how to update with Magisk but I do not find it clear enough. Are these the steps I need to take in order to not-brick and update my phone with the Feb update.
1. Uninstall Magisk by "restore images" option.
2. Install OTA
3. Reboot to reinstall Magisk on second slot
Magisk is NOT installed on the second partition! And I prefer not to flash back the original image just to do that. My system should be read only and I do not have twrp, I never had, I updated my Google services framework from apkmirror and I got the update, now how do I apply it without soft bricking?
Update
Step 2 failed, "installation problem". Wtf do I do in order not to lose Magisk or data?
Edit
I've uninstalled Magisk but haven't restarted, hoping to get a solution where I keep my sh*t since that's what the guide said...
Edit 2
I'm reading the other thread but I'm having trouble finding a single useful information there, quote one if you find it, it might be my autism that I don't see a solution in that three pages long thread. Tell me I need to MiFlash this sh*t so I calmly jump through my window instead of wasting the whole night on making it work, then wasting another day on backing my sh*t up.
Edit 3
Fully uninstalled Magisk by instructions of an indian guide. BOOTLOOP.
Note to self, stop following southern asian guides.
Downloaded ROM and MiFlash, flashed flash_all_except_storage.bat.
Shook for 4 minutes until "success" mark, successful reboot.
Edit 4:
follow the regular magisk flash guide https://forum.xda-developers.com/mi-a1/help/how-to-root-mi-a1-february-ota-update-t3757934
If you got into bootloop after Magisk uninstallation, you did modify system partition at some point. This is also the reason why you couldn't install OTA. Magisk OTA update guide works perfectly fine for unaltered system partition.

That's what I figured, but how? I just did exactly everything I did before the OTA attempt, I just installed few modules and touched nothing else. At which point could've I touched system partition?
So I'm reading now that apps can still alter /system with the Magisk root perm, so, I what about one of these apps.
1. Does anyone know if they can mess with the system?
BusyBox
Greenify
Lucky patcher (this c*nt is my main suspect)
Titanium backup
2. Can we somehow make sure that we haven't touched the system partition before OTA attempt?
3. Once I've redone everything (flash Rom without storage, install OTA, install Magisk), my system shouldn't be touched now, right?

Please keep in mind that Magisk is 2in1 package. First of all it provides root access, any app with root access can modify system directly. Second feature are systemless modifications, but you must follow defined rules to make them work.
From your list of apps, BusyBox would be my first suspect. You must use Magisk BusyBox module, the standard BusyBox is installed directly to the system partition. Lucky app might be the culprit too, though it depends on which features exactly did you use.
Yes, once you reflash stock ROM, apply OTA and install Magisk (the correct way), you're system partition will be ready for the next OTA.
Someone mentioned one command which could verify the last modification date of any partition, but can't find it right now.

Don't bother trying to find it, it exists, I'll make a dedicated thread at some point, thanks for the answer, BusyBox seems logical.
The correct way to install Magisk? I just flash Ranjit's patched img from the official thread on Magisk root, that should be the correct way.
I just use lucky to patch cirtain apps, so that shouldn't be a problem
Right now, I'm giving Magisk root perm to Greenify, Lucky Patcher and Unified Hosts. Also both Greenify and the Unified hosts adblock have their own modules in magisk.
Hopefully I still haven't touched my system partition.
I encountered the error as well after trying the Pixel OTA method. To flash the update successfully, I flashed stock January system and boot img via fastboot and it updated properly after. Then I just patched the stock Feb boot img and went back to fastboot. Once there, i did the fastboot boot command with the patched Feb boot.img so I got root back after updating.

HI,
I have a redmi5+ rooted. I use luckypatcher (i applied some patchs to some apps) and i have installed once BusyBox (didn't do anything in special).
I want to know if it is secure to flash the full update?
PS: how do I confirm if the system files and vendor are ok to proceed?
Thanks

But i want to know if it is secure to flash, because i used these two applications.

Tried manually flashing firmware with fastboot and now no system

Ok so I've been having a hell of a time with this phone so far. I have the boost mobile variant (xt1766). I unlocked the bootloader, installed twrp, but forgot to make a backup before flashing supersu, after which my phone would no longer boot so I flashed lineageOS. It booted up fine but I had no 3g connection so I wanted to go back to stock. I downloaded the stock firmware, but couldn't get RSD lite to install on my computer so I extracted all the files and flashed them manually with fastboot. After that my phone wouldnt boot and TWRP couldnt mount the data partition so I couldnt restore my lineage backups. I had to format the data partition in order to restore from backup but now I have nothing on internal storage, and my phone wont boot into system unless I boot into factory mode from the bootloader. It boots up fine in factory mode but now I have no network connection, no service whatsoever.
Under sim status it says Network: unknown, cellular network type: unknown, Service state: Radio Off, etc. I tried manually turning the radio on but that didn't work. I really just want to go back to stock but I don't understand how to accomplish this. I flashed everything in the firmware package in the correct order, and somehow it just rendered my phone useless. any help would be much appreciated. I've tried just about everything and I'm at a loss here.
Update:
I successfully got back to stock. For some reason executing the fastboot commands manually one at a time didn't work so I made a bat file with all the proper commands, executed it, and this time it worked. Not sure why it didn't work the other way but it might be because I didn't flash the stock recovery so as not to replace TWRP. Apparently when flashing firmware its all or nothing.
Are there any custom ROMs with 3G functionality for this device? Cuz so far every single one I've tried gets no network connection but this stock ROM is lame.

Not "lame" unless that's the latest descriptor for a reliable, fully functional, device optimized ROM that just works. If you want additional bling/tweaks flash Xposed framework and a few well regarded modules like GravityBox.
Alternatively, you can cycle through the various custom ROMs and decide which suite of compromises you're willing to live with. Suggest a careful read of the relevant ROM thread before diving in. Be sure to backup what works (including stock!) and store those nandroids on a SD card and/or off-device.
Good luck.

That's because you're on boost, not many ROMs here have CDMA support. There is a fix in the help section. But stock is fine for me. Gravitybox and all features of any of the broken unofficial ROMs are all there. Rock solid, and LTE. But flash away dude.

I haven't been able to install the Xposed framework. Xposed installer says my CPU architecture is incompatible. When I flashed Xposed v89 for nougat my phone wouldn't boot past the boost logo. I keep hearing about people getting Xposed working on this device but I can't figure out how they're doing it. I would love to be able to have gravity box on this ROM.
Apparently the purityOS guys made an unofficial work around a while back but all the download links in that thread are dead and I can't find it anywhere else. It's my understanding that i need to be able to set selinux to permissive on boot in order to install Xposed.

No, regular Xposed. Wipe cache and dalvik, and wait. Let it sit 5 - 10 minutes. It has to optimize everything. Make sure it's the arm build. It works fine, just gotta let it sit. First boot takes a good bit.
Or use magisk, and install Xposed through that.
Do not use that old purity crap. That's why the links are dead. It's old crap. Xposed works fine with no extra steps or messing with selinux.

That's BS; don't overcomplicate things. Xposed framework installs fine in enforcing mode. Make sure you have the correct framework for Android 7.1 (SDK 25) and your hardware (arm). You will also need the corresponding management app. There is no need to wipe anything before/after flashing the framework although doing so can't hurt. First boot will take awhile; patience is a virtue.
Got Xposed working now with gravitybox and edge in full effect so this stock ROM is now much more tolerable. I guess I had the wrong version of Xposed installer and didn't wait long enough for boot to finish.
It broke safetynet though which I fully expected. I'd rather use the systemless Xposed magisk module so I can pass safetynet but I can't get any magisk modules to install successfully either through magisk or by flashing with TWRP. Apparently I'm not the only one having this issue either and it doesn't look like anyone has found a fix for it as of yet. I guess for now I'll have to live without Pokemon go lol

Well yes there is most definitely a fix. Your problem is the f2fs loopback bug. Your solution is the f2fs loopback bug workaround module. It's in the magisk manager app. Download there, but install it in twrp. Then magisk modules will work. You must have halted your research a little early because this is well known, and posted in many places.
You still won't pass safetynet with systemless Xposed. Which a little reading would have also revealed. But, you can turn off Xposed in magisk , then reboot and pass safetynet. Do whatever it is you need safetynet for, then turn it back on and reboot. You must completely uninstall the Xposed you have to use magisk Xposed. You must use the Xposed installer APK that's linked in Xposed for magisk so it recognizes systemless Xposed. So uninstall Xposed with uninstaller zip, uninstall Xposed APK. Wipe caches. Then you can just go in magisk manager, scroll to the bottom of downloads, install Xposed sdk 25 module. Also Xposed installer APK linked 8n the readme that pops up when you click the Xposed module in magisk downloads. See screenshots below.
Also, there is more to pogo than safetynet. There is an entire thread devoted to it (more than one) in the magisk section of the forum.
You have a bit of reading to do in order to do the things you want. It's all very easy to find. You don't seem to be looking very hard.

I'm well aware that the problem is f2fs loopback but due to the bug I'm unable to install the fix. Can't install magisk modules so a fix in the form of a magisk module doesn't really help me. Ive tried installing it with TWRP a couple times with no success. As far as PoGo I've actually never even played that game. Was just curious about it.
And I'm not sure what app you're referring to but that "wow" face is a chrome shortcut. Changed it cuz I didn't like the default grey square.

Trend continues; reread post you're disparaging. Or module OP. f2fs loopback 'fix' gets flashed in twrp or via fastboot (for the adventurous).
I edited my post shortly after your quote. Tried installing with TWRP more than once. Doesn't show up in magisk modules.
Just flashed with fastboot and now it seems to have worked. Fastboot for the win.
Maybe all caps will help out

bootloop after magisk update

after uptade magisk my phone stuck in fastboot . i cant go to recovery . what i can do ?
phone is over or i can fix it ?
Open Magisk Github, and try to find a solution in the Magisk Troubleshooting
You say you "updated Magisk". Since you didn't describe how, supposidely you did by flashing Magisk through TWRP or by Direct method from Magisk app/mngr
Unfortunately, those two ways are most risky. If anything goes wrong (if you don't have TWRP backup) you cannot go back to the previous working configuration
It takes just few minutes more to extract and patch the boot.img and to flash it. If anything goes wrong, you flash the original unpatched boot.img or boot.img that was patched by your older Magisk and you are back in business.
To fix the bootlop now, it will take more than few extra minutes for extracting, patching and flashing the image every time when installing and updating Magisk

You should better have updated Magisk by patching the boot.img, then flashing (from Fastboot or TWRP) - in that case, if you have bootloop you simply flash back your previously patched img that used to work
I cannot know what went wrong. Maybe, there is a module that is no more compatible and causing the bootlop:
- Reboot to TWRP, Advanced, File Manager and navigate to /data/adb/modules
Each folder corresponds to one module.
Add an empty file named: disable (exactly as that) to each folder/module (or only to those modules you suspect they might be causing the bootloop).
Once you disabled the critical module, you can boot to system and from Magisk app further manage your modules.
Or, from TWRP flash to Boot the original boot.img extracted from your OTA zip file.
When you reboot to system, there will be no Magisk but next time you install Magisk it will find and activate old modules, probably causing again the bootloop
Or, download Magisk apk, rename to uninstall.zip and flash from TWRP to fully uninstall Magisk (and all its modules, everything)
Recommending first method, but you see the other two options as well

Connect me pls on discord fkr me its like chinese now it would be easy if you tell me live what to press on the teamwin mode. The reason i update magisk was because i had a module to block ads but suddenly it didnt work so i opened magisk and i saw the update and did the direct update like how i always updated my magisk before.

I don't use discord and I have work and private life
I gave you directions that if you knew just basic things about flashing and File mngr in TWRP, about using Magisk, etc, would be nite than enough to follow directions
Most annoying users are those who install'nuclear bomb' like Magisk, do updates, etc, but never spent their time to learn (when things work and it's easier) how to use, read the Instructions (available by one click to Github from Magisk app), etc, and then when (sooner or later) get a brick, cry for somebody to guide them to click here, there, etc.
You can still use PC and google and fill the gaps from my instructions to what/how you must click here and there
Sorry to be brutal but I really don't have time

Its not that i didnt look up on youtube about flashing in revovery mode. When i did search for more information i get those videos of people in india talking their own language. Np if you dont have time and on other topic someone said that they wint use discord because it wont be public for someone else with the same problem but i was gonna make photos with the steps i did for fixing it. The thing is i cant find the uninstall. File or the older version of twrp. Skip i wont takr your time good luck with your private life
And about the installing nuclear bomb thing... magisk has the direct install option which is the nuclear bomb button (sometimes) the reason why my phone got into bootloop is a module which isnt working anymore its called energized its for blocking ads. I saw that it didnt work... before it worked fine i thought maybe i need to update magisk but thats why it went into the bootloop. I managed to delete the module through twrp mode and here this is for you

You don't need to delete modules (some of them, like V4A might be complicated to install again) - just disable them through still the working Magisk app before you go for updating
Or patch and flash the image instead of taking Direct install. There might be other reasons to cause bootloop, not just incompatible modules.
If it bootloops when you flash the newly patched img, just flash your old img, previously patched by the older Magisk version, that used to work for you
As simple as that - and no bootloops, no emergency help needed, etc

I am surei have the older backup in my internal storage of my phone but i dont know from where to recover that and on the internet they say everything and i am scared to make it worse than it is. I didnt use the phone for a long time because my lcd got a short circuit and i replacet it. On internet they say this bootloop problem can occure when you skip some updates some say to install a program on pc then go in download mode and fix with the program but i unpluggrd my pc and tv because me and they got too old for eachother.
Now i am just trying different things what i see on youtube and twrp says this: check picture.

I've had this ****, i just used abd to flash a new twrp img and dirty flashed the ROM after it flashed magisk back on again, only problem I got was safety new which idk how I solved but I think was using lsposed

H918 Rooted and Encrypted on Stock?

Is there any way to have this phone rooted with encryption working? I would use Lineage, but it doesn't support VoLTE. I'm aware that TWRP will very likely never work again once the phone is encrypted, but that just means that I would have to flash everything I need before encrypting.
I'm on AO 20h ROM currently. My idea was (after making sure I never need TWRP again)
1. Flash stock 20h kernel zip without dm-verity and forced encryption disabled
2. Flash stock 20h boot.img (not sure if this step is necessary)
3. Reboot into system
Does this have the possibility of working? If not, what do I need to do to make this work?
Also, where can I find the stock kernel and boot.img?
I attempted to just flash the boot.img I extracted from the 20h kdz. This didn't work, because when I rebooted it just brought me to fastboot every time.
Edit: Second attempt was to extract the 20h kdz to get both the boot.img and the system.bin files. Then I patched the boot.img with Magisk Manager on my other phone, and moved it back to the sd card. To get the system.img from the 52 binary files, I used the KDZ Extractor which has an option to merge system files into an image. My plan was to flash from TWRP the system.img and then the patched boot.img, but when I went to install the system image, I got a warning message that the image was too big. It shows as 6GB on my computer, and the system partition is 5.4GB.
The only other idea I had in mind was to flash the 20h kdz, but interrupt the installation before it boots for the first time and "encrypts", then go into fastboot and flash the modified boot.img, but this seems excessively risky.
Edit Again: I DID IT!
And I'm not even locked out from using TWRP! Though I'm stuck on Nougat - 10p - with the method I used.
1. Patch extracted 10p boot image with Magisk app
2. Flash 10p with LGUP
3. Flash TWRP to recovery with Lafsploit, reboot to recovery
4. Factory reset from TWRP
5. While still in TWRP, flash the patched boot.img from 1.
Now my next goal is to deodex and try to get signature spoofing working so I can use MicroG. I've tried the Smali Patcher, which appeared to work, but it gets stuck on the T-Mobile splash screen. Same thing happens when I try to install Xposed with any method.
Hi there Pineapple!
Not too many people do care about H918 anymore. I am just like you trying to get something done, so reading everything I can find. I will point out the things I've learned already, but do remember I am not a dev, nor a senior member, not even a very experienced one.
So, above you were saying :
1. Flash stock 20h kernel zip without dm-verity and forced encryption disabled
2. Flash stock 20h boot.img (not sure if this step is necessary)
Well, the "boot.img" contains the Kernel and the Ram Disk, or at least this is what I've read in Android Internals - Jonathan Levin [1st Ed] free on his site. So, now it should be clear that if you'd do 2, it will overwrite 1.
About Encryption and Root:
ENCRYPTION:
Encrypt your phone before rooting, -> root, -> apply ROM. Not the other way around! Tested on Android 4-6.
Once you root or install various ROMs you lose the ability to encrypt your device.
You will have either hanging, rebooting, or the animation stalling
Discussed: http://forum.xda-developers.com/showthread.php?t=2791587 and
http://androidforums.com/threads/how-to-encrypt-a-rooted-device.866968/
Un-root if already rooted. Encrypt. Re-root.
If you Root with SuperSu, you have to manually kick start SuperSU when rooting after the encryption is in effect
Also see about issues with TWRP and Encryption in some devices
(Unable to decrypt the data partition on boot due to bug in TWRP)
(yep, H918, and it seems to be happening on stock ROMs as opposed to AOSP)
not sure if on H918 it is related or not to TWRP bug
Secure Boot (aka dm-verity) also complicates persistent rooting. <- look like you already took measures here
Xposed:
Xposed now also exists as a MAGISK MODULE, so no longer DETECTED if installed thru MAGISK <-try this
Had some issues with Android 7 (Nougat) but most were fixed. <-maybe try different version?
De-Odex
Why? Are you going to be theming your apps? AFAIK,
ODEX = (pre) Optimized Dalvik Exe file format (compressed, not fully compiled yet), separate from .apk
android apps are stored in .apk packages, not as easy nor fast to run as if already Odex-ed
De-Odexing just means having your apps on ROM sort of "collected" back to ".apk". You need that where you want to have an easy access to app resources, i.e. for theming.
QUESTIONS:
1. Could you, please, post the versions of all the components you've used? Like TWRP, Magisk..
2. So, microG doesn't work on rooted stock Nougat on H918? (Damn, I wanted to de-google)

Yes, while doing this I did learn that the boot image contains the kernel. Looking back, that statement seems silly now that I know that. You are correct about encrypting before root. I did boot into the ROM and did the initial setup, then went back to TWRP (which thankfully had no error decrypting) to flash Magisk via the patched boot image. I did get rid of secure boot too, but I don't know if it was necessary in this case.

I tried three different ways of installing Xposed. First was through the Magisk Module, but this just made me get stuck on the T-Mobile screen. Had to remove the module from TWRP. Second was "systemlessly" as described here: https://magiskroot.net/install-systemless-xposed-framework-nougat/ . This had the same result. Third was by using only the Xposed Installer 3.1.5 apk, which didn't seem to do anything at all.

Deodexing the ROM is necessary to add signature spoofing, which is necessary to install MicroG, so it can pretend to be the real Google Play Services. Usually in the past I've done this with the Nanodroid patcher https://nanolx.org/nanolx/nanodroid but it didn't work here, which was odd because it did work on the Alpha Omega Oreo ROM (which didn't have working encryption).

1. The TWRP that's on the laf partition is the one that FWUL 2.7 installed. The TWRP that's on my recovery is 3.5.2_9-0-h918.img. This is the latest official release. To unpack the boot image from the stock kdz, I used LG Firmware Extract 1.2.6.1. I moved the boot image onto another phone which had the latest Magisk Manager app on it (23.0) to patch it with Magisk.
2. Not so far it hasn't. I've deleted everything Google with System App Uninstaller, /d/gapps, and adb. So I'm going without Google Services or MicroG for now. I'd like to change that though, since MicroG makes it far more livable.
So, you have the same end goal as I do - privacy. Have you considered buying the de-googled phone from Brax?
Honestly, this never ending enigma with H918 has me wondering if I should just do that. I mean, I don't sweat some learning and work, but now that the V20 forum is basically dead....

That reminds me of the people on ebay who try to sell 12 year old Thinkpads for 3-4x what they're worth just because they flashed coreboot on them. Except it's way easier to install a custom ROM on a Pixel than it is to flash coreboot. The Pixels are also very different phones than the V20 - no removable battery, ir blaster, 3.5mm jack, good DAC - but if you want the most private and secure smartphone, a Pixel with GrapheneOS (not Lineage) is what you want. Flash it yourself, it's way easier to do it to Pixels than LG's.
Same here.
May-be not that crazy, 3-4 times, but yeah, he sells Google Pixel 4 XL 128 GB with lineage for over $700 where that same phone is $380 on Swappa, lol. It's not as drastic as you memory of e-bay, but it is twice the worth, still.
But then again, considering how much Rob is doing for the community to propagate the awareness, may-be this isn't all that high of a price. Some busy people won't even blink at his prices, but would never invest this much time to decipher everything. Sadly, I, myself is a sucker for the know how, instead of focusing on making money.
You are right in that I did pick this phone as "last phone with removable battery" myself. I actually do remove the battery from time to time when I don't want to be tracked, and drop the phone in the steel covered glove compartment, where no weaker field communication can ever reach it.
Hey, thank you so much for the version numbers, if I decide to go that way, I'll use those exact ones! (So far, do not want to cross into ARB1, but it seems that the lafsploit only works with 10p...)
You know, the Patcher is also available from NanoDroid installed as a Magisk module. Their (Nano) description here:
GitHub - Nanolx/NanoDroid: [MIRROR] See https://gitlab.com/Nanolx/NanoDroid for main repository
[MIRROR] See https://gitlab.com/Nanolx/NanoDroid for main repository - GitHub - Nanolx/NanoDroid: [MIRROR] See https://gitlab.com/Nanolx/NanoDroid for main repository
github.com
states that NanoDroid includes:
on-device framework-patcher for microG support (signature spoofing), with automatic de-odexing up to Android 8.1
Is that the method you tried?
Nanolx says that his patcher patches the sig spoofing support into one of the three locations: Magisk NanoDroid module, Magisk itself and /system. When you were using the patcher, did you see any of these choices?
Also, do you know that the dev of Magisk now works for Google? Now, I know that absolute majority of people would not see anything weird here, but I do, cause I don't trust Google, and thus want to de-google my phone. Specifically, a small conflict of interest while working for google and developing a software that supposed to oversee and support the escape from that same Google by de-googling the phone. Some stockholders might find this quite funny and demand that something is done about this.
I would try older Magisk. I know from other threads, that on 10p, some of the versions of Magisk that did work were: 16.0, 21.0, 21.4 ...

As long as Magisk itself is FOSS and hasn't been proven to be spyware, I'll trust it. The later versions actually have gotten better about privacy, since it now doesn't require internet. And the goal of the Magisk project isn't to de-google your phone. It can aid in de-googling, because you can uninstall system apps, but Magisk is just to gain root.
As for how I tried to use the patcher, I tried from TWRP, which gave me the error "failed to mount /system unsupported a/b device," and then if I tried to flash it from Magisk Manager it gave the error "failed to deodex services.jar"
When you say you tried to flash it from TWRP / Magisk Manager, it is not clear to me if you understand that Nano Patcher is also available as a Magisk module, and if you have tried to add that Magisk nano module or used the Patcher by itself as provided by NanoDroid in a stand alone installer. Since I haven't used Magisk yet myself, I do not know if has the flashing capability and that is what you referred to, or if that meant you added the module. Like I said, still learning here.
I do understand that Magisk is only a systemless root , not a patcher or microG.
The H918 is not an A/B device. Not on Nougat nor Oreo in any case. Obviously, you know that.
So, your device is being misidentified as a much newer device.
I think that if you had tried a version of Magisk or the Patcher that is not YET aware of A/B devices, then possibly such mis-identification would not happen.
Of course the fact that it happens thru TWRP, gives Magisk somewhat an alibi.
I still think it is worth trying. May-be older Patcher first, then with older Magisk.
I keep holding Magisk in my attention because without it doing its job correctly, you could not take the next step, the one that isn't working.
Finally, Try some of these: https://download.lineage.microg.org/h918/ ROMs, they already have signature spoofing handled. I would think an older one might work, as I saw several threads mentioning that the later versions of LOS don't run well on H918.
Also, here is thread you might want to read and post your situation into:
[MODULE/SYSTEM] NanoDroid 23.1.2.20210117 (microG, pseudo-debloat, F-Droid + apps)
NanoDroid NanoDroid is a installer for various OpenSource related things, most noticably microG and F-Droid. It supports direct /system installation, both devices with or without A/B partition scheme, aswell as Magisk Mode (module) installation...
forum.xda-developers.com
That thread discusses NanoDroid used as a Magisk Module, and there are few users experiencing a similar situation (with different errors) and some advices.

I'm taking the nanodroid patcher zip from their website and attempting to flash in TWRP, which I've successfully done before on other phones. I also tried using the same zip and installing it as a module in Magisk. I don't think there's a separate file meant specifically for use as a Magisk module. I believe the a/b error in TWRP has something to do with the fact that when I'm in TWRP and I go into the "Mount" menu and select System, the check box only remains ticked for about 5 seconds, then it automatically unmounts again. No idea what the problem is there. I suspect if that weren't an issue, I'd get the same exact error that I get when trying to use the patcher with Magisk.
As for LineageOS for MicroG, that's what I was using before going back to stock, and it was great. But it's sadly unusable as a phone because of the lack of VoLTE. If not for that, this could easily be my "forever phone" with the huge battery.
I'm also now having a strange issue where many system functions (recents, settings menus, autorotate, second screen, statusbar) are running unusably slow, while any other app runs perfectly fine. I have to do more testing to figure out what this is, though. Edit: stuck at T-Mobile logo again. Gonna try to do all this with stock Oreo.
Oops, I am sorry, I forgot, you have said that in your first post that you already tried LOS, man. So, we are stuck? It gets stuck on T-Mobile splash, meaning this is a bootloop, or rather a bootfreeze. I think your other issues must be related to this issue that is preventing you from patching for signature spoofing.
I've been reading up trying to find what is going on with your phone, and I stumbled against this:
You simply swipe the bar to allow TWRP to make modifications to your /system partition. Swiping on this particular screen, you are giving TWRP permission to mount your /system partition as R/W (Read & Write) as opposed to the default of /system being mounted as R/O (Read Only). However, please beware and know what you are doing. If you so much as mount /system as R/W via TWRP, regardless if you actually make changes, a kernel secured with dm-verity (device mapping verification) will prevent your device from booting into the Android OS. Never mount /system as R/W without first verifying whether your kernel has dm-verity enabled. If dm-verity or AVB 2.0 (Android Verified Boot) is enabled, flashing a systemless root script like Magisk 16.0 will patch dm-verity to disabled, as well as disable force encryption in the fstab.
You said you disabled the secure boot. This is aka dm-verity .
Now in your case, you are using the encryption, which needs dm-crypt to be active, correct? These two are related because they both are managed by a DM - device mapper.
When you said you have disabled the secure boot (dm-verity), do you mean that you have maybe chose some options when patching the boot.img with Magisk ? Or did you do it thru some other method?
I keep seeing references to "No Verity Opt Encrypt" without a good explanation of what it is or how to use it or when to use it. I am curious if you have applied that or not, and if you did, where did you read about it.
So, my current thinking is that if you actually failed to disable the dm-verity, this should take you to the bootloop or freeze. May-be DM failed to separate the two and kept both enabled?
The fact that you have touched the /system as r/w according to green above, should trip the dm-verity to bootloop you, if dm-verity is somehow still enabled.
I still do not understand though, why you are receiving a failure to patch.
Also, you have mentioned that you have used a "Smali Patcher". Knowing nothing about nothing, I of course assumed you meant to type "Small Patcher" , i.e. some patcher. Now cleaning up the details I looked it up. Oops. It is actually a real thing. It supposed to examine your system in step 1, and generate a Magisk module, and in step 2, you add that module to Magisk and check it as enabled. I just want to confirm that this is exactly what you have done and this brought you to T-mobile splash screen.
I actually may try LOS for microG, what version did you have that was great?
Because from what I was reading the LOS for 918 has many issues (no 5G tether, no 2nd screen, no WiFi call, etc)

Now in your case, you are using the encryption, which needs dm-crypt to be active, correct? These two are related because they both are managed by a DM - device mapper.
When you said you have disabled the secure boot (dm-verity), do you mean that you have maybe chose some options when patching the boot.img with Magisk ? Or did you do it thru some other method?
I keep seeing references to "No Verity Opt Encrypt" without a good explanation of what it is or how to use it or when to use it. I am curious if you have applied that or not, and if you did, where did you read about it.
So, my current thinking is that if you actually failed to disable the dm-verity, this should take you to the bootloop or freeze. May-be DM failed to separate the two and kept both enabled?
The fact that you have touched the /system as r/w according to green above, should trip the dm-verity to bootloop you, if dm-verity is somehow still enabled.
I still do not understand though, why you are receiving a failure to patch.
Also, you have mentioned that you have used a "Smali Patcher". Knowing nothing about nothing, I of course assumed you meant to type "Small Patcher" , i.e. some patcher. Now cleaning up the details I looked it up. Oops. It is actually a real thing. It supposed to examine your system in step 1, and generate a Magisk module, and in step 2, you add that module to Magisk and check it as enabled. I just want to confirm that this is exactly what you have done and this brought you to T-mobile splash screen.
I actually may try LOS for microG, what version did you have that was great?
Because from what I was reading the LOS for 918 has many issues (no 5G tether, no 2nd screen, no WiFi call, etc)

The "No Verity Opt Encrypt" is a file that disables verity and forced encryption. If you rename the zip, though, you can make it only disable verity or only disable forced encryption. I did flash it with no-dm-verity, but from what you found it looks like Magisk does this for us so it's probably not necessary.
The fact that it bootlooped isn't due to me mounting it. I did that several times before without bootlooping. The issue I had with it was that it automatically unmounted /system after a few seconds, which is why I believe I can't deodex from TWRP.
For the Smali patcher, I don't remember how I attempted to use it. So far my attempts to root and encrypt stock Oreo haven't gotten very far, so I'm going to try this again.
I just used the latest version. I don't use 5G tether so I wouldn't know. The 2nd screen "works" but it just extends the main screen, making the cameras into a notch type thing. I can live without wifi calling, but lte calling won't work, which is, again, the only thing keeping me from using Lineage MicroG.
DUH !
I can't believe sometimes how dumb I actually am. Of course, it says right in the name of the file: "No Verity + Optional Encryption" ! [slamming my forehead into the table] I swear I read it thousand times, but for some reason it did not make any sense to me. I knew it does something about this subject, but I never took it literally!
Thank you for letting me know.
It is cool how the arguments are sent by renaming the patch instead of using the optional parameters. I like that. Magisk does that as well. You flash Magisk.zip and it installs Magisk. You rename it to unistall.zip and flash that, and it uninstalls Magisk.
Please, keep posting if anything changes. If I read something that makes me think I've picked up the scent again, I will let you know. For now I don't know what else to read.

You uninstalled Android Device Bridge? I am curious as to why? I mean, yeah, it's Google, but it's most likely harmless, and very useful. Does it call home or something? At some level the entire Android is Google. Yeah it comes from HA, but Google pays. And money talks. I am curious why.
Anyway, I might have found something , I am not sure, but it looks interesting:
So, I am reading this:
Internal Details
The Magic Mask for Android
topjohnwu.github.io
It says:
Paths in /data​
Some binaries and files should be stored on non-volatile storages in /data. In order to prevent detection, everything has to be stored somewhere safe and undetectable in /data. The folder /data/adb was chosen...

Did removing ADB, somehow messed up the /data/adb folder, and then that messed up Magisk? Is this why some of the operations you have attempted have failed? Like you'd install a module and it would be like you didn't even do anything?
I didn't remove adb. I debloated using System App Uninstaller. For some things that didn't work I used /d/gapps. For other things that didn't work I used adb.
Been messing around with Oreo the past couple days.
I *can* get stock Oreo to work with root and even MicroG - everything works great. Except it refuses to encrypt. The option is there in the menu to "Encrypt Phone". The battery was above 80% and plugged in, I tap the button, and it just takes me to the T-Mobile splash screen and quickly to the lock screen. I know MicroG isn't causing it, since it has this issue with or without MicroG. I get the same result whether I installed 20h from a TWRP flashable zip or if I installed 20h from the kdz with the kdz writer tool https://forum.xda-developers.com/t/tool-kdz-writer.3649818/. It isn't an issue with the recovery partition, as I left that stock and just use TWRP from LAF.
The less ideal option for Oreo at the moment is to have it completely stock from LGUP and just debloat with adb. This means no root or MicroG, but those are the least of the issues. It looks like if you uninstall Google Play Services without also installing MicroG, you get constant error messages saying "Messages has stopped working." No problem, just remove the messages app and use QKSMS, right? Well removing Messages breaks Contacts, which is also the dialer. Removing the dialer and contacts, replacing them with Simple Dialer and Simple Contacts works, but then you get the constant error message "LG IMS has stopped working." Removing LG IMS gets rid of the error messages but, predictably, breaks VoLTE.
Edit: It may not have been Google Play Services that broke the Messages app.
Quick reaction. You are likely right. It probably wasn't the removal of GPS that broke Messaging. There are so many different fixes for that error on the net (which you probably have already mostly tried), that it suggests many different causes for the error.
But, interesting how all that stuff is chained. Almost looks as if intended that way. Don't deny them saying a good bye to google outright, just make it an incredibly deep rabbit hole.
This comes to mind: try "freezing" messaging or anything lower on this chain, in hopes that it is the uninstall that removes some shared dependency and that they haven't thought of you trying to freeze them. I know you wouldn't care all that much if the chain didn't end with VoLTE.
