Question How to prevent the Android 12 T-Mobile upgrade? LE2117 - OnePlus 9

Is there a way to prevent the automatic T-Mobile update to android 12? Currently, I have Android 11 installed and I super happy about it since I have no issues with it at all, but my phone is trying to update itself to Android 12 which I would like to avoid because I heard horrible stories about the newest android version on OnePlus 9. I turned off the "Automatic system updates" under the Developer Options but on the official OnePlus forum I learned that this doesn't work since the software upgrade is pushed by T-Mobile not by OnePlus (at least this is how I understand it). Therefore, is there any workaround? My phone is network unlocked (but not bootloader unlocked) and if possible I would like to permanently disable the upgrade notifications (and the automatic upgrade) without altering the original firmware too much (like unlocking bootloader or installing any custom ROMs). I heard that there is the ADB tool which could be helpful but I'm not quite sure what commands should I issue to fix my problem.
The biggest issue is that every night I have to remember to turn off my phone since otherwise upgrade will be enforced between 12am and 6am which at the beginning wasn't a big deal, however, after two months is getting bit annoying...

If you are willing to unlock bootloader, this can be fixed in 3 seconds.

Well, so let's say that I'm going to unlock the bootloader (I was expecting that I will have to do it eventually, and I found a good tutorial of how to do it here: https://www.oneplus.com/support/answer/detail/op588). How could I prevent the upgrade to Android 12 then?

The second you root it. Done

Turn on data saver and set your WiFi to metered and done! No root needed!! It's working!!

I just accidentally bought a rooted HTC M8 on eBay with issues. Should I keep it?!

I am in Australia and have just recently bought an HTC M8 on eBay which was originally listed as new, and factory unlocked for $530. A few days later I found out it was actually rooted now unlocked, but was originally locked to Sprint. This was confirmed by a Sprint Connections application update etc, and the root was confirmed by the SuperSU app that was already installed in the phone. I'm recently confirmed this by the Root Checker app.
My phone's software is Android version 4.4.2, HTC Sense 6, software number 1.54.651.8, HTC SDK api LEVEL 6.17, PRI version 1.52_003, Kernel version [email protected] #1 SMP PREEMPT, Baseband version 1.05.20.0321_2.
The phone is pretty functional for everyday use except for the following issues:
- The internet network settings had to be manually obtained from my carrier as the phone did not automatically pick it up.
- The internet seems slower than usual (Signal strength -79 dBm 17-20 asu) compared to my old phone (Xperia Z1), despite the settings being specifically on 3G/UTMS mode which is faster than having it on Global Mode, and the required setting with my carrier Optus.
- I cannot access anything under System Updates. i.e. Update profile, Update PRL, UCICC Unlock and most importantly, HTC software update. This update takes >20minutes to search to no avail. This error message at times pops up when I try selecting Update profile: “vDM Client has stopped unexpectedly. An error report will be sent to HTC to help us improve our products”. This error screen would pop up intermittently when my internet didn't work but, I rarely see it now.
- Wifi would randomly switch on. I've turned off all system selections that may be caused on this. I haven’t tried booting my phone into safe mode to determine if an app is causing this.
I don't know much about phones (I had no idea what rooting was until I looked it up to get a rough idea), so I'm wondering if you experts could be some advice
I'm planning on keeping the phone for about 2 years and wondering what issues I may receive from having a rooted phone with the already above issues? Would the phone play up more? Can I use my current android version for that period relatively smoothly?
I am able to return my phone for a full refund but I don't have a spare phone and don't want to go in to the hassle of doing so if I can keep the phone (I would prefer to leave them negative feedback on eBay to be honest ). What do you guys think?
Thanks in advance for any asisstance.
Update your phone to android 4. 4. 4

Just reflash the stock rom and relock the bootloader and everything should be fine.

No Wi-Fi on Nexus 5 - on any version of Android

The Wi-Fi on my wife's unrooted Nexus 5 (Sprint version) which was upgraded (via OTA) to Marshmallow last month suddenly stopped working last week. The slider would get hung while moving from Off to On (like it was trying to turn on) and therefore was not detecting any available Wi-Fi signals.
After trying many things, I eventually did the extreme and did a full factory data reset. No dice. Still not detecting anything.
Figuring it might be an OS issue with Marshmallow (given we're seeing a lot of forums indicating Nexus 5 issues based on Wi-Fi with both Marshmallow and Lollipop), we downgraded the OS first to Lollipop and then all the way back to KitKat (4.4). Still not working. At initial phone setup, the phone is not detecting any available WiFi signals and gets hungup trying to find networks for me to choose from - so I end up having to skip this step.
Any other tips out there on what I can try? Is this a sure sign of hardware problems? Don't think my wife's phone is under warranty any longer (have had it slightly over a year, I think).
PS - Now I can no longer even upgrade the phone (OTA, at least) from 4.4.4 because my phone is saying it needs Wi-Fi to download the update - with no option to do it over my data plan.
I'm in the same situation and it appears to be a hardware failure. The wifi chip can't be replaced so a motherboard swap is required.
You can upgrade to the latest stock ROM by flashing the entire ROM from a command prompt in Win7.
Plot thickens
So, I figured out a way to get the OTA's over LTE (by manually changing my phone's date up a week). While going through each OS update from 4.4 KitKat to 6.0 Marshmallow (about 5 or 6 rounds of them) my phone briefly was able to detect WI-FI, I believe during set up at 5.1.1 Lollipop - and I was able to get on my home network.
Probably should have just stopped updating after that, but definitely was not detecting anything after that. I lost it during one of the Lollipop updates - well before getting to 6.0. Not sure if WiFi was actually working well or not.
Maybe the chip is in the process of failing? Not sure but it seems like you are having better luck than me.

I wish. Don't want to go through all those steps again after doing a clean wipe to have a fleeting glimpse of Wi-Fi.

Hi, pagalbengal. I'm having the same problems right now, and I wanted to check with you to see if there have been any developments with your situation over the past month. Still hopeless? Have you contacted Google tech support? Do they still even support this phone? Thanks for any info.
You guys might want to try reflash the modem firmware.
Couldn't get my wi-fi to work so I replaced the motherboard. Every stock and custom ROM I tried could not enable wi-fi.

Rooting and impact on ability to receive future OTA? - the last 5 yrs in Apple land

Question: Does rooting the device prevent me from receiving OTA updates? Do I have to "re-root" after each OTA update?
Background: I used to be really into custom roms, TWRP recovery, Xposed mods....back in the days up to the LG G2 and Nexus 6. So I am super rusty on Android changes in the last 5 years. I am now coming back from iPhone jailbreak land. I just ordered a 7 Pro directly from Oneplus.com and super am excited. I spent the last 12 hours reading up on Android related info. I plan to unlock the bootloader and root the phone right away so that I can #1 enable native tethering, #2 system-wide adblock, #3 youtube adblock.
I would like to stay close to stock as possible to receive OTA updates. The only thing more important to me than OTA is being able to #1 enable tethering. #2 and #3 are nice to have, not must haves.
I'll be using this device with T-mobile in the USA.
Your help and patience would be much appreciated. Sincerely, thank you.
Either re-root after ota, or just flash the full update in twrp then reflash twrp/magisk for root/recovery. If you want to hide tethering usage on tmo there are a few ways to do it but I use "
VPN Hotspot - tethering/Wi-Fi repeater"

I want to use native tethering (if it works) so that I can enable Tasker automation - turn on wifi hotspot while I am in the car. Although I like this option as well. I could connect to my home OpenVPN server.
Thanks. Sounds like I can just quickly reflash the two files in succession and I am good to go?
5+ years ago, doing this sometime causes problems when the version difference is very significant. For example, going from Android 9 to Android 10 OTA, I would have to wipe user data and start over. Not sure if it's still true today.

Bluetooth and Wifi, or change the custom rom?

Hey guys,
I'm living and working with my Z5 Dual since years and I have the latest Lineage OS with the updates it brings (old Android 7.1.2, latest and last update as of 5 February). But I am getting more and more annoyed by two things which drives me into severe considerations what to do next: changing the phone? changing the custom rom?
The issues I face with the latest Lineage Os are the following:
I cannot connect--although trying everything--my electronic scooter via bluetooth with the app of the provider (it's name is SoFlow). The app on all other Android devices I have, stock Samsung and custom roms all see and connect to the scooter.
My Wifi connection drops always after a couple of minutes when the Z5 screen is not used and the display turns off. That is super annoying and it only re-connects as soon as Ihit the power button to turn on the screen.
So my questions are now: Can anyone provide me with useful help regarding issues 1 or 2 on the latest Lineage OS? And if not: what can I do, should I switch to a different custom rom (which one, maybe Carbon Rom, maybe another One?) or should I go back to a rooted stock rom? Any help is appreciated. i know the devices is old and Android 8 or 9 is as unlikely as nothing else at the moment, but at least the issues mentioned should not be there in Android 7...

LG stylo 5 No service.

Hi there! I've recently had an issue with my phone where i have no service. My bars have a little x next to them, as though i have data turned off.
Here's the info I've gathered:
My preferred network option is stuck on 22.
It tell me to connect to WiFi (despite being connected) when i attempt to send a text, but tells me to turn off airplane mode when trying to make a call
Nothing data related works, but WiFi is fine.
Now, I've found another thread from early 2022 with the same exact issue. Only thing is, they were having the issue after updating to Android 10.
My phone is still on Android 9. Like, I'm pretty sure its not even the most recent version of 9 either. Like, i have build number PKQ1.190302.001, which isn't the latest build for even 9, let alone 10 and onwards. However, i can't update. I've checked in the settings and everything, it keeps telling me there's no update available, which i don't believe.
I get my service through Boost Mobile, so I'm not sure if they didn't get the update, or if something else is going on. Either way, i have no service, which is a serious problem as i have no other phone and can't get a new one until late February.
I'm sorry if making a new thread wasn't a good idea, its just the only other thread I've found was from a year ago, and my issue is technically different.
Thank you in advance for any help!
