[Delete me]Revert to previous system update? - OnePlus 7T Questions & Answers

I utterly HATE what this recent update (to Android 12) has done to my phone, especially that Battery Charge Limit is broken. Is it possible to revert to the previous update (11.0.9.1) without wiping and reinstalling everything fresh?

Thanks for reply, i will update it now.
Will the update through the lg mobile tool wipe everything ( apps etc ) ? Is it recommended to do a factory reset after the upgrade?
Thanks.

Yes, it will erase everything. I'm guessing a factory reset wouldn't be necessary since I think it starts you with a clean slate to begin with after installing it, but if you prefer to do it, it wouldn't hurt I suppose.
LG Update tool
LG Update Tool or whatever you call it. I used it yesterday for update from official first update (vj10?) to official ICS. It leaved all contacts, messages and WiFi access codes intact.
Everything as it is described on LG page (remove spaces, add www in front)
lg . com/us/ NitroHD-Upgrade
1. Install driver
2. reboot
3. install Tool
4-and-5. connect phone and run tool
In ~25 minutes I've got ICS installed.
The only issue I have is the battery life. My usage mode is "Mostly idle" and battery lasts 1 day +. Now it is running out 10% per hour. Not sure what is the problem.
There is my issue, I cannot get the tool to see my phone is connected? Where in CM9 do I activate the "PC Software" mode or have the USB connection menu come up?
In my case (Stock ROM) that was in phone's Settings -> Connectivity -> USB settings then it was a menu { Mass Storage, Charge only, PC Software, MTP something } and "Always Ask" (I'm Paranoid ). I'm not familiar with CM, so check other threads. May be it's easier to get stock ROM first.

No, it won't erase everything. just start LG Update tool & connect your phone and start updating. after everything is done you will see your installed apps are still there even call log sms everything remains there.

Fail on LG's part. In that case, I'd suggest that everyone who installs this ROM perform a factory reset after installing it.

Not a fail at all... It backs up your info before doing the update.
Personally, I find this to be a huge win. I find it very cumbersome and annoying to have to go through and download my apps and customize the settings.
Way to go LG!

No, it doesn't back anything up. It's just means it's not clearing your data partition at all during the update. It's the same as not doing "facory reset/wipe data" from CWM before installing a ROM.
The problem is that can lead to all kinds of weird problems once you're in the new ROM. It's probably why some people report bad battery life and others don't, etc.

I would suggest that you do a factory reset and see if the battery life improves after doing that. You'll have to set up the phone again though. Make sure your contacts are either stored to SIM or Google so that you don't lose them, etc.
If you don't know, you need to turn the phone completely off, then hold down volume down and power button at the same time -- keep holding until the text appears that asks if you want to factory reset. Then let go and follow the instructions.
There shouldn't be any reason to install the update a second time.

Thanks for your useful point about factory reset. i did factory reset and downloaded about 30 apps which i installed earlier. now i will notice battery life. i will confirm it after using a day.
Does anyone know if this update could apply to P936? I'm currently on CM9-RC2 for P930...
Thanks in advance, cheers!

All data was missing, home screen defaulted to icons. It was as though I was signed in as a guest
I had to do a full reset
Sorry for bumping this post, but i have just had this issue after my battery died on a night out, next morning turned it on but gave this error instead.
I'm in the same situation after my battery ran out and rebooted my device.
All my apps have lost their settings. I have to reconfigure everything.
Did you guys found any solutions in order to restore this?

Can someone help please?

I was rooted on 5.1 but the phone wasn't stable so I decided to go stock by flashing 6.0 and upgrade to the latest through system, my phone keeps rebooting every now and then even after factory wipe and cache clean... Any suggestions?

I think it would help everyone out if you provide more details.
1) What do you mean you "flashed 6.0 and upgraded through system"? TWRP, Odin, OTA?
2) Are you now unrooted?
3) Do you have stock recovery now?
Yes I'm unrooted with stock recovery. Lost root but it's okay. Wanna keep the phone stock now. I used Odin to flash 6.0

Yes I'm unrooted with stock recovery. Lost root but it's okay. Wanna keep the phone stock now. I used Odin to flash 6.0
Also that when the phone is at 15 percent it turns off.. Goes into a bootloader but after wiping cache it turns on.. Shows 2 percent battery.

I had a bad battery that eventually would do just that (reboot phone at ~15%). Is it only rebooting at low battery? If that is the case you might consider getting a replacement battery.

Yes it only reboots at 15 percent. But I guess his right. Will opt for a new battery.
Also if I may ask, is 5.1.1 better than 6.0 for this phone? To keep as stock in terms of battery and stability

I personally prefer marshmallow because of the added doze and permission features. I noticed better battery life and performance because of doze mode (no longer need greenify to kill every app). Samsung's TW ROMs are generally very stable so I wouldn't worry about that too much. Anything after 5.0.1 was very stable for me on this phone. I would highly recommend MM for this device (it even has wifi calling if you can get it to work).

First off, thanks for replying. I've been trying and trying but hardly anyone responds here. Your suggestions are good, I'll upgrade to MM tonight.

July Verizon Update running very hot!

Can I just flash the June update and go back?
No issues when I used the July update (non-Verizon), but yes you can go back
If you don't mind setting up your phone again you might want to try a factory reset before going back to June. Sometimes after an OTA update or an accumulation of OTA updates over time something in the phone gets corrupted (cache, old app data, code that isn't properly updated or erased in an update) and the best thing to do is a factory reset to start fresh.

Mine did as well, I suspected teh July update.
5 days in though it seems to have cooled off and is working at the temps I am accustomed to ~30c at idle.

Okay thanks. That's good to know. For now I have flashed back to June. I may flash July and factory reset as was suggested above. For the past few months I have been updating by removing the "-w" from the flashall batch file and maybe it's caught up with me. I also tried wiping the davlik cache in twrp but that doesn't seem to work.

Try just clearing your cache partition from settings > storage. It may help in some cases too if cache is corrupted.
Factory reset will pretty much guarantee fix.

You might be right that adding -w caused your problem. There is always a possibility that some user data in an app that gets saved can cause problems after the phone is updated.

Well I factory reset and installed the July update. The phone is fine now and not not hot but it seems a lot faster too. The only issue I ran into was that evidently my apps weren't being backed up to my google account, so I had to manually install them again. Thanks for your advice!

I've had that happen after a factory reset or Rom flash in the past too even though I knew my apps were being backed up--they are by default unless you turn the feature off. I don't know why that happens but sometimes it does. I'm glad everything is working fine now. Sometimes giving your phone a fresh start by doing an occasional factory reset or completely clean flash is the best thing you can do. The fact that it seems to be running faster now is very likely true. Again, glad you got it sorted out. I'm actually running the beta of O and if you like how the Pixel runs on Nougat I think you will be even happier when O officially rolls out in August. The boot time on O is almost instant, battery life is slightly better and should improve more if more apps optimize their code for O, and the phone runs very snappy even though O is still in beta.

Interesting. So O is supposed to become available in August. Will my older apps still work or will they all have to be updated by the developers? Also- for future updates would I be better off doing an OTA vs a complete flash (with the -w taken out)? In any case it sounds like at least every other month I should do a reset and reinstall anyway. What is the risk in just not updating every month? Thanks!

I've encountered a handful of apps that don't work on O but they probably will by the official launch date. But an app being optimized to help provide better battery life is something that goes on in the background that you won't notice unless you are a programmer that can analyze code or knowledgeable tech writers shame app devs publicly who don't do it. Android O has the ability to limit an apps background processes so it uses less battery but my understanding is that it only happens if the app developers voluntarily write code that allows O to do that to the app and a lot of devs are probably not going to do that if it is voluntary.
I'm not sure what your setup is but if you are manually flashing updates presumably you have a custom recovery and possibly root. Some Pixel users have reported successfully flashing OTA updates anyway because of the dual partitions on the Pixel but it wipes out your custom recovery and root and returns you to full stock and I'm not sure doing that works reliably. I don't know that the Flashfire/Flashify (I don't remember which app goes with TWRP) works on the Pixel. I don't have any experience flashing OTA updates manually via bootloader rather than the full monthly update. Personally I was never a fan of removing -w from a full flash because it can always lead to potential problems that aren't necessarily completely obvious. I always prefer to clean flash to give the phone a clean start, but that's just my own preference. I didn't like to dirty flash custom Roms either --i would always do a clean flash every month and set up my phone from scratch.

12 to 11 downgrade on G981u1 - how?

12 is so buggy and filled with UI lags. Terrible.. so I fired up odin, selected all 4 major files (I used CSC Home to preserve my user data) and flashed the latest 11 XAA version for my phone (which is what i was running prior)
Unfortunately, the phone wouldn't boot. Got an android can't start error; it suggests doing a factory reset which I didn't want to do just yet.
So I re-flashed all 4 files again, this time from 12 build (XAA) and i'm back up and running, no user data loss.
What's the right way to downgrade? Do i have to use CSC and wipe my user data? Any way to downgrade w/out doing that?
Thank you!
I also wanted to go back to the A11 and that's the problem. When I put the appropriate files into Odin and ran it, the flashing stopped at the word UH in a moment. After a few tries, I had to reinstall the A12. Then Odin didn't stop anymore.
