Clear out Android System Update? - LG V20 Questions & Answers

I have a brand new H918 that I was able to install TWRP and root. It's on 10i and it has an Android System Update waiting to be applied. I turn off automatic updates in the Developer Options, but the update was already downloaded and wants to be applied. Is there a way to clear out this downloaded update so it stops bugging me to do it? Also, how do I apply stock updates going forward with TWRP installed? Is there a flashable stock 10j?

I don't know about the AT&T model, but on the VZW model, there are two different system update apks. If you freeze/disable them both, you'll kill the notifications. One can be disabled through the Application manager. The other needs to be done through Titanium Backup or with the "pm disable" ADB/shell command

Go to root>cache. you'll find the update zip in the cache folder, not in fota. Just delete it.

The folder is empty. I booted to TWRP and cleared the cache. The notification still shows up.
Edit: to clarify, there is a fota folder under /cache but it's empty.

OTA with TWRP?

this may have been asked, but i'm new to the nexus 7. i rooted it right away, and put TWRP on. probably shouldn't have but i like doing nandroids. i was excited for the OTA and want to just install it since my tab got it, but it won't obviously since i've got a custom recovery (duh i should've thought of that..) and i don't want to go flashing roms yet (i like keeping everything stock right away, it's so smooth)
so my question is, is there a way to go back and flash the stock recovery somehow so i can OTA, then put TWRP back on? i can't find the stock file to fastboot flash or anything
You can either download the OTA update manually and flash via TWRP. or do a full 4.2 stock ROM
http://forum.xda-developers.com/showthread.php?t=1989158
Warning: there have been mixed results from the early adopters on the OTA patch. I was running 4.1.2, TWRP, and SuperSU. I lost both SuperSU and TWRP when I upgraded and a handfull of apps are not working right with the new multi user file structure.
The way I did it was
1) Download the OTA zip from the thread I posted above
2) Moved that to SD Card (I moved via Google Drive, you can use USB if you want) I did the whole thing while waiting for a flight without a computer handy
3) Reboot to TWRP Recovery
4) Flash OTA Zip
To get Root and TWRP back I did the following (note, I have SuperSU pro and the survival mode was checked)
1) disabled SuperSU and reenabled which prompted to update Binaries
2) flashed TWRP via ROM Toolbox

thanks kangy! i also lost both when i flashed.
the reason it didn't work was that i frogot i played with my build.prop and had apps frozen on titanium.
so i disabled and reenabled SuperSU, but no prompt to update.
i'm using rom toolbox now to install but it keeps telling me install failed...basically because it doesn't have root i presume. any ideas?
Alright try this.
Go to SuperSU settings and and click on Reinstall under Cleanup, it will give you a prompt and tell you it will self close and to re-install from the market. (Mine never fully uninstalled which I assume is due to it being flashed to ROM, I checked under the App manager and it only had a downgrade option so) Anywho. If it did uninstall go ahead and redownload it from the market, if it didn't check the market anyway, the Dev published and update for it to help with 4.2 multi users.
Once you get it reinstalled and/or updated from the market go back to the settings and Toggle off Enable Superuser, close the app, re-open and then re-enable superuser. You probably will want to give it a reboot at this point. (Ive restarted my device a hundred times since going to 4.2 from trying to work through the bugs. Once you restart test a root app. I used Adaway for the test. Important, if the app fails or gives an error about not having root, try again. After I went through all of those motions SuperSU was pretty slow for a while with giving root access, usually the second request from the app wakes it up. Since then though it is back to being snappy with zero lag.
Yes, the reason you can't flash TWRP through ROM Toolbox is that requires root. Once you get your SuperSU working try flashing the latest TWRP again, it should only take a few seconds to flash. Let me know how it goes, I'm subscribed to the thread. I may not be the smartest guy on XDA but you are in the same exact boat I was last night!

First, determine if you have root or not. Open TiBackup, if it opens correctly and you can see all your apps listed, you have root. Otherwise it will say "Failed to obtain root," and quit.
If you have root, then great. If not, you can flash the SuperSU zip in TWRP/CWM: http://download.chainfire.eu/282/SuperSU/CWM-SuperSU-v0.98.zip
I haven't tried flashing superSU, I've always flashed Superuser zip [google "superuser zip"], and then installed superSU from Play store.
Once you have root..
Go to Settings > Security and check allow installation from non-market apps, and uncheck the security feature that checks all apps for being malicious.
Then try it. If you still cannot restore apps, you might have to install them with adb.
I just updated someone's N7 to 4.2, and as usual I backed up everything in TiBackup.
Then I backed up the TitaniumBackup directory [because I had to do a full factory reset].
I then extracted all the .apk.gz files with gunzip. [in linux OR adb: $ gunzip *.apk.gz -- for windows, I suppose you would have to use 7-Zip].
Then I tried to install with pm:
Code:
for i in *.apk; do pm install $i; done
But every one was giving me an error, INSTALL_FAILED_INVALID_URI, I couldn't figure it out. Found a thread said to chmod 755 /data/local, but that did not fix it.
So what I had to do, was on my linux PC:
Code:
for i in *.apk;
do adb install "$i"
done
So I finally was able to batch install my apk files.
after that I restored all apps data.
Nandroid back ups not possible after 4.2 update
After updating my rooted N7 to 4.2 OTA I re-rooted using Wug's Nexus Root Toolkit 1.5.5 and realized that Nandroid back ups are failing.
I had no problem creating such back ups while on 4.1.2 and using his Toolkit 1.5.3. I guess the reason may be that the 1.5.5 Toolkit does not have the latest build incorporated.

why are you even using a toolkit? it's a nexus!...
Root by flashing Superuser zip or superSU zip in CWM/TWRP.
Make nandroid backups in CWM/TWRP, and you should have no problem.

NRTK 1.5.5 would not flash the 4.2 custom rom I fed it either. Just kept stalling out with errors that it could not find the zip file.
So I booted into TWRP and flashed it with no problem at all.
I also did backup in TWRP and checked everything but saw no mention that is was a Nandroid backup. How can I be sure?
i'm trying to nandroid back to a 4.1.2 nandroid i have, problem is, twrp has different directories for nandroids in 4.2 than 4.1.2...so it can't find the old nandroids and i can't find the 4.2 dir where twrp stores them now. ugh. such a damn headache for an update that it turns out i didn't want lol
Read my post below, I was having the same problem but got back on 4.1.2. You have to use the twrp explorer and relocate the twrp files since 4.2 moved them.

How to cancel/remove a scheduled OTA update?

I have TWRP and root. I just let the system install an OTA security patch, but the phone restarts into TWRP, and when I reboot into system, after about a minute a dialog pops up about "Android System Update" with a progress bar running for a bit and the phone restarts again.
Is there a way to cancel this scheduled auto-update at boot (e.g. by removing a file somewhere using TWRP)? I don't want to install this update anymore.
I figured it out. I went to the /data/data/com.motorola.ccc.ota folder, which is the Motorola Update Services app, go to the shared_prefs folder inside that, rename all files in there (a bunch of XML files) to something like .backup and the auto update on startup went away.
Now it is asking me to install the new update again every now and then. Is there a way to ignore this update permanently?

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

Updating rooted 6T the right way, i.e. w/o rebooting upon load.

When I update my rooted 6T, the update is successful but the phone reboots every time the lock screen appears. What is the proper way to update to latest OTA w/rooted 6T?
Given:
No TWRP.
Encrypted storage, which is why no TWRP.
Magisk modules disabled prior to update
Fingerprints, codes, etc removed prior to update
I've followed these steps with the same reboot result.
Update Process for Rooted Users
1. Magisk Manager > Tap "Uninstall" > Tap "Restore Images" (DO NOT REBOOT)
2. Now Run the System update to download and install the full OTA zip (DO NOT REBOOT)
3. Close all background apps
4. Open Magisk > Tap "Install" > Tap "install" again > Tap "Install to Inactive/Second Slot (After OTA)"
5. Finally tap Reboot after Magisk installation is complete.

The steps you posted are exactly what I've followed for every update with no problem. Make sure you're using the full update .zip, not the incremental zip
BTW, TWRP works perfectly fine with encryption
Does the system update automatically download the full update.zip? I have a system notification that a system update is ready to download and install. Is that the full update.zip?
Do I need to make sure I disable fingerprints and other security? Do I need to disable magisk modules? Do I need to disable or uninstall anything, other than Magisk, before I install the update?

When I was using TWRP, TWRP could not see the downloaded file because the file names appear encrypted, ie scrambled letters for names.

Had the same issue. Updated this way several times with no issues. 9.0.15 I had problems. Had to back up internal files and wipe data.
But I also had no limits installed when I took the update which I believe caused this. The no limits 7.2 was incompatible with the latest update and Everytime I pushed root it would do the reboot to recovery instantly on lock screen upon boot. If you flash twrp in recovery, your phone will boot normally without root so you can back up your files before doing a full wipe and put your files and apps back in.
But my method was take the full ota from the one plus Ron updater in os. Then let it boot normally. Then reboot to fastboot and put twrp and magisk on like you did when you initially rooted etc

System update with unlocked bootloader without on system updater

For some reason the section "System update" in the phone settings is greyed out. I do not have a custom recovery and no access to adb in the recovery to sideload my system rom.
I tried adb sideloading it on my device while it is turned on but it fails with:
* cannot read 'OnePlus8ProOxygen_15.E.36_OTA_0360_all_2105181828_5d18f419b.zip' *
Before it was failing with another error message I can not remember.
Is there a way to install the stock rom? I am rooted and have access to the root shell with magisk.
have you tried this?
as for the system update being greyed out im not sure. I dont know if having a device that is not certified would do it or not, but you can check that in your play store settings in the about setting, then at the bottom. Or possibly from an app maybe
check if this is disabled com.oneplus.opbackup
apparently it can also be one of your magisk modules that broke it. go through them one by one to find the culprit
if you still want to go back to stock rom you will need the msm tool for your device.
Be best to provide your OS, device and variant.
Sounds like it's been locked down.
