How to downgrade from Android 11 Beta to Android 11 stable - OnePlus 8 Pro Questions & Answers

Hi guys, I'm on Android 11 Beta 7 at the moment, using IN2020.
Felt that my battery drain is high. My SOT is around 3 to 4 hours.
So thinking of getting back to stable and see how it goes.
Appreciate all advice. Thanks.

You should be able to adjust the settings on the Oxygen Updater app to download the standard OS11. Remember that this will wipe your phone, so you might want to back everything up first.

Thanks RD.
Have tried a few ways. The only workable method is to reinstall Android 10 version then upgrade to Android 11. But of cause, it means wiping clean the phone when it downgrades to Android 10.

[Q] Nexus 4 Update

Hello, I will get a Nexus 4 now in early May, but I came up with a question about updates. If i leave the phone with the stock rom, I'll lose my apps and settings to replace the future stock Android 5.0? And if you install the Latest build of Cm 10.1 when developed the custom rom Android 5.0, i will need to wipe and lose all? Thanks ;D (Sry for my bad english)
No if you update your phone from stock 4.2.2 to 5.0 you'll lose nothing. Everything stays as it is.
Yes, if you install any custom rom over a stock rom, you'll wipe and lose all. But all of your applications will be downloaded automatically from your gmail account and for like launcher settings or kernel settings you can backup all the info or you can use titanium backup app in order to backup everything.
So there is nothing to worry about.
Edit: By the way i am not really sure about the thing about going from 4.2.2 to 5.0. For minor updates like from 4.2.1 to 4.2.2 you lose nothing. But i don't really sure about 4.2.2 to 5.0.
Hmm i take that, but anyone can tell me if i install the Cyanogenmod 10.1 (4.2.1) When come the Cyanogenmod 5.0 (Assumption), the team of cyanogen make this update with no wipe necessary?

If it is a big update with many changes a full wipe must be done in order to get it working correctly. You can always easily restore user apps with Titanium Backup or adb.

It's recommended to do a full wipe to avoid problems if you're going to install a new rom. The developers will most likely have to wait a couple of weeks or so for Google to release the files for KLP for them to access and use. No rush. No rush. :good::laugh:

If you factory reset you'll still be on lollipop. I'd recommend SimpleAOSP, hasn't failed me. You can find that in the N4 Android Development where youll find the toolkits to toot your phone. Also in this section there's a sticky thread called Nexus 4 ultimate root guide

Please i want something good and official its IMPOSSIBLE 3 HOURS of battery A DAY ?? :|
can someone help me please because i dont arrive at 12pm, with this ANdroid 5.01 can someone give me a tutorial with how to install ROM ,
ps. i never flash or root smartphone before !
thanks
Patience is a virtue, my child. It won't kill to check out the development forum to see what's going on with CM12. Remember the Lollipop just came out and it's going to take a long time till there's going to be an official CM. Use the toolkit and root your phone and unlock the bootloader and install a custom recovery. Word of caution, backup anything important on your phone, unlocking the bootloader will wipe your phone. But that's a good thing, now you have a clean phone. You can either stay on stock rooted or use the rom which I'm using. It's called SimpleAOSP http://forum.xda-developers.com/showthread.php?t=2932090

You should have a app that makes your phone wake. The problem is not with android 4.4 or 5, it is something else.
Check if you have NFC on, wifi on (wifi searching, while wifi turn off, on), mobile data on, gps on, bluetooth on, google now on, sync on, check your apps (you can use BetteryBatteryStatus (need root) https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats&hl=en), you can use Greenify to hibernate some apps (https://play.google.com/store/apps/details?id=com.oasisfeng.greenify&hl=en).
You can also do this. Plug you phone and charge it to 100%. Use the phone until it shutdowns (when it reach 0% battery). Then, with your phone turned off, plug it again (use the wall charger) and wait until it charges to 100% and wait 30, 60 min more. Then use your phone normally.

Get rid of battery doctor and the other apps you use to delete cache and I bet your battery is better. Then get gsam or betterbatterystats and determine where your wakelocks are. Minimize those

First of all, do what jd1639 said. Get rid of those apps. You are wiping the cache, but the android automatically build the cache again. If you use app killers, it kill the battery and doesn't provide any benefit. They do more harm than good.
The android 5 is for nexus 4 too. Go to the battery settings and see what apps are consuming the most battery (if you don't want to install betterbatterystats). Post printscreens of your battery settings and the apps that consume the most battery so that we can help.
Here is a thread that helps you get root and install recovery and custom rom: http://forum.xda-developers.com/nexus-4/help/guide-ultimate-nexus-4-root-guide-t2018179
But if you backup your apps and restore them, it is possible that you will have the same problem with another ROM, since it is very probably an app that is killing your battery.

[Q] Contact Synch using loads of data after PA install

I recently installing PA 4.6 Beta 6 on my Nexus 4 because Android 5 just wasn't working out for me. Unfortunately I've encountered a serious problem: my phone is now using about a gigabyte of data per day! I only noticed this when the default data warning limit kicked in, but initially dismissed it as a side-effect of downloading/synching everything after the install. I reset the data limit and thought nothing of it until 2 days later when the 2GB limit kicked in again.
I've installed Network Connections by Anti Spy Mobile which seems to indicate all the data usage is from Google Contact Synch. I can only imagine something is looping, but seriously how could it be using so much data!?
I've un-installed anything I don't use and turned off automatic backup, but the data flood continues. A search for similar problems hasn't revealed anyone else with this problem, so I thought I'd ask on here before removing PA and switching to Cyanogen Mod.
Cheers.
It's not the ROM causing this.
#stayparanoid
Yep - was never insinuating that it was PA; just that it occurred following the install.
Sadly I haven't been able to work out what was causing it and have had to flash a new ROM before heading back to work in the morning or my mobile provider is likely to have a fit. I've flashed CM and will see how it goes, but I may well come back to PA or go the PAC ROM route. I'm definitely a fan of the PA features and am grateful for the work done by the dev team.
Did you try to accept the 5.0 update while on the 4.6 beta? It would probably have come through a notification. If you told it to download, it will never stop trying until you clean flash

It was actually 4.45 I downloaded because I wanted a stable release. After install there were some OTA updates and I did download them assuming anything OTA would be fairly stable, but I didn't know/realise it would have tried to bring down a major new version (5.0). Looks like it could have been my mistake then for thinking it would just be updates to the version I'd installed.
I did take a backup before switching to CM so if I get some time I might flash the backup and check what version it is.

If it was the google ota, it wouldn't install anyway.
We have not provided an upgrade ota from 4.x to 5.x
Its likely you were still on whatever version you installed, but the ota was constantly trying to download

Stick with PureNexus or update to Oreo?

I'm currently running the latest version of PureNexus and debating installing Android Oreo. Are there any huge downsides? Is it buggy, slow, etc? In other words, is it daily driver ready for someone who uses their phone all day for music, video, games, EVERYTHING and still wants to tweak the os to their needs.

Unless you're worried about the security updates, just stay on PN. PN for Oreo should be out soon as well.
That makes a lot of sense, thanks.

I was on PN since I got my 6P and updated to Oreo as soon as it came out. I don't regret the decision at all. Battery life is as good or better than PN (I routinely end the day with 4+ hours of SOT and 35-40% left. Your experience may vary depending on usage), performance is wonderful, and I haven't found any major bugs yet. All of my favorite mods work (EX kernel, Pixel mod, Camera NX, WakeBlock, and a few others I'm forgetting).
The only downside is some modifications require a bit more work. For example, to resize the navigation bar and add dynamic coloring I had to extract, modify, and push framework-res.apk instead of having those options built right into the settings menu. There's no custom quick settings tiles and I can't change the number of rows/columns, but that isn't a big deal and I've learned to live without it for now.
As stated above PN based on Oreo should be out within the next month or two. Beans posted an announcement on G+ yesterday explaining that he had a family emergency that slowed down development on PN O, but he is actively working on it as much as he can.

I went from PN to 8.1. Honestly, stick with PN. I used it for a couple days and I am downgrading right now. My battery life was significantly worse (on 7.1.2 I ended the day at ~40-50% battery. On 8.1 I was at ~20-30). I didn't notice anything great about Oreo and found myself missing PN.

Not sure aware of this or not, but beans posted in the PN thread he's working on Oreo for the angler. So you'll soon have the best of both.

I had that issue too. Spent waaaayyy to long trying to figure it out. I think 8.1 has a different encryption method. You need to wipe the phone completely and then do a nandroid restore (or flash PN)

Don't mean to sound like a complete noob, but how did you go on about wiping the phone completely? I've now tried so many things, reflashing TWRP, reinstalling stock firmwares, using Wug's Nexus Rooting kit, ... I can acces fastboot, what do I need to do to be able to reinstall TWRP? Because when I try it right now, I can't acces it. It goes back into the boot loop.
