Manual System update - LG Velvet Questions & Answers

I have a USA TMobile LM-G900TM14j. 4.14.141+
I just did an initial boot from the factory and it has android 10 on it. I do not want it to install 12. Is there a way to get Android 11 on it manually? I have turned off auto system updates. If it installs 12 I am hosed so trying to tread lightly here.

[SOLVED] Cannot download OTA update

I have an OPO with the following firmware:
Cyanogen OS: 11.0-XNPH05Q
Android: 4.4.4
A while ago I upgraded to CM12 and decided I didn't like it, primarily due to the MMS issue. So I restored to 11, until now and want to upgrade. I go to About phone > System updates and get the following:
"An update is available for your system
XNPH05Q Incremental
A Cyanogen OS update, XNPH05Q Incremental, is available for your phone. You will be notified when it is ready for installation.
This will prepare your device for upgrading to Cyanogen OS 12.0.
Update size: 8.7MB"
The problem is, when I press 'Download update', nothing happens. Nothing. Nada.
Some information which may be pertinent:
Constantly connected to Wi-Fi
Device is rooted
I am currently overseas (in another country away from my usual home)
Xposed Framework with Xprivacy installed (I have tried disabling Xposed but upgrade still doesn't work)
TWRP 2.8.5.1
Any suggestions?
SOLVED
The issue was that the System Update process was disabled in ES Task Manager. When I enabled the process, the download proceeded.

I can't update my Google Pixel from Android 8.0 to Android 8.1

Hi everybody, i have a doubt
I signed up for the beta tester program for android 8.1 via OTA on my google pixel, but when it finishes loading and reboot to install the version, it tells me that it can not install any solution, since several times I do, but I still can not upgrade to android 8.1, I am currently on android 8
I hope. can you help me thank you
The same happens for me too.. ( and for most people.. )
There is a fix for this.
1. Download the OTA update.
2. Goto settings and do a Factory Reset (YES.. a reset)
3. After device is reset, the downloaded OTA will be installed automatically.

Rollback from 12 Beta to Android 11 and an update that I can't get

Hi everyone.
I just bought a Pixel 4a and I enrolled in Android 12 Beta version updates and I got on Android 12 Beta, but then I decided to get back to Android 11. I did the flashing with the flashing tools website and then when the phone started and I got connected to the internet right at the beginning of the setup it says that I need to update my phone (I downloaded the latest factory image for September and flashed it on my phone) it says "Your phone needs to download an update and restart. Size 1617.2MB" when I click Next it gets to updating screen but it gets stuck there no matter how long I wait. I though maybe it is because I did it through the website so I did it manually using this tutorial but I have the same problem.
When I continue without a connection to the internet I can get passed this process and start the phone but when I check for the updates same thing happens.
Did I just broke my phone and I won't be able to get the OTA updates anymore?
no no no... You only have to unsubscribe from the website "android beta 12". Afterwards it will no longer ask for an update and everything will return to normal

Update... Android 12 can be rooted using Magisk Canary
I was able to take an OTA update to Android 12 on my BL unlocked, rooted, custom kerneled Pixel 3! I started the update accidentally by hitting that pop up reminder and after a minute of thinking what to do (i did not want to lose my data!!!), I held down the power button to force it to reboot during the update. I have had this work to stop an OTA update and restore it perfectly to previous state. Anyway, it did NOT work this time, and it updated to A12 perfectly! No loss of data, no loss of custom kernel, but i did of course lose root. Also.... when i checked the update version in settings, it wanted to update AGAIN, from Oct 21 to Feb 22 (which is just an Emergency Dialer patch). My phone still shows Oct 21 security patch in settings, but shows the Feb 22 firmware (...016.C1), which suggests the patch was only a tiny fix to the 911 Dialer and did not affect anything else. So this time i let it update, which i started to think was stuck or looping after waiting about an hour, but finally i checked the progress and it was done, requesting a reboot! So i rebooted it and behold, its now running final security update to the Pixel 3, and all i need to do now is root with Magisk and install SafetyNet Fix. Which is the ONLY thing i can think of as to how it was able to do a factory OTA update while rooted and BL unlocked! The SafetyNet Fix patch may be so good that it bypasses the Google security measure that refuses to allow OTA updates on rooted, unlocked Pixel 3s. Yup, on a GOOGLE PIXEL! I used to have to unroot and install the factory kernel to do an OTA sideload on my old Essential in order to update and not lose data, but i was told that you could not update to new Android versions without losing your data on the P3, so Ii just figured my Sept 21 A11 firmware was the final update until a phone upgrade. Anyway, just wanted to pass on the good news that you CAN perform a factory OTA update from A11 to A12 on the Pixel 3 WHILE rooted and unlocked and with a custom kernel, but I of course have to recommend you do so on your own, and if anyone has an unused or non-daily driver P3 that want to confirm this good news, please do so and help convince the disbelievers ! The ONLY thing i would recommend is that you have the latest "Android 12" version of SafetyNet Fix installed with the switches on in Magisk, which is what i had. Its the only thing i can think of that would allow Google's Safety Net to bypass the security restrictions. OK then, hope a few of you give it a try to show im not a nutcase, lol.
Question kind of related to this... Was the P3 kernel updated in Android 12 to fix that race condition that causes freezes if using systemless hosts? With A11 I always had to make sure I installed a custom kernel before Magisk and enabling systemless hosts to keep my P3 from freezing.

Question OnePlus 9 cannot update from 2113_11_C.60

Hi all,
I have a weird issue - I have updated my OnePlus 9 EU last year over Oxygen Updater, but managed to install India-only update on EU phone and now in settings it shows 2113_11_C.60.
After scouring internet I found that C.60 was India only update.
Now, I haven't received a single auto update since May 2022.
I have tried downloading incrimental updates to C.62 both for 2113 and 2111, but neither local upgrade nor special oneplus app was not able to update.
Also tried full install of C.62, no success.
Even tried full upgrade to latest EU build LE2113_11_F.75 - same result..
The local upgrade through settings constantly shows "verification failed" no matter what file I choose.
OP's System Update app would fail after showing system updating for a minute, with 0% progress.
As I understand, I somehow managed to install Indian version of incrimental update on EU phone, but now I am stuck on it.
What are other reinstall options on OnePlus 9?
Can I somehow force install if I connect over PC?
Many thanks for the help!

Forgot to attach screenshots...
Index of /list/Unbrick_Tools
Find the one compatible for your device whatever stock would be and run the msm recovery tool. This will get you back where you need to be to be able to update to latest software.
Otherwise you can try editing the file payload_properties.txt inside the update zip and changing oplus_update_engine_verify_disable to 1. This way your phone should skip the verification process entirely. Keep in mind that this could still result into bricking your phone because of this unintended update path but since the alternative would be using MSM tool why not trying anyway.
