How to uninstall/downgrade from recent CM update? - ONE Q&A, Help & Troubleshooting

Hi Guys,
Yesterday I revived notification that new update is available, so not thinking much I installed it. After update I realized that my phone is not getting service, or getting it only outside, for short time.
My current version of CM is 11.0-XNPH05Q. I rooted my phone today and now I am wondering if I can install this version of CM - cm-11.0-XNPH33R-bacon-signed-fastboot_16GB?
I know this might be silly question but I am complete newbie, please advice.
Thank you!

Just flash one of Calkulin's stock rooted ROMs from the dev section, he has one for each CM11S release.

hey, I want to downgrade to 44s too (as I have bluetooth problems). I'm fully stock and not rooted at all( :cyclops: ), I updated to 05q manually by flashing zip in stock recovery... can I downgrade the same way? flashing 44s zip (I guess it's full and not incremental like 05q) without wiping anything to keep my data?

No you can't, you need to unlock your bootloader and flash the stock images with fastboot to downgrade properly.

Will this void the warranty?

Nope. It's pretty much impossible to void the warranty on one of these things. You can unlock the bootloader, you can root it, you can install custom recovery, custom ROMs, custom firmware, custom kernels. Pretty much the only things that void the warranty are bricking it, and physically opening the device up.

[Stock Recovery] Use 4 OTA

Here is the stock recovery that was pulled from the newest ota.
http://www.megafileupload.com/en/file/520717/stockrecovery-img.html
This can be flashed with fastboot and the latest ota can be installed as normal. You can then flash TWRP or CLOCKWORKMOD recovery back when finished.

YOU MUST BE ON STOCK ROM
I THINK THIS IS WHAT I NEED!
Someone help please! Lol.
I'm currently S-OFF and rooted on stock rom. I want to remove S-OFF and root if possible and update to the latest OTA. I am also using TWRP as custom recovery. Can I flash this and then update via the OTA and accomplish what I want?!

Leave S-Off, the OTA neither affects or is affected by the S-Off.
You just need the stock recovery to flash.
Yes.. u don't need to take it back to s-on.
Get back to stock Rom (may be on it now if you haven't flashed any roms)
adb reboot bootloader
fastboot flash recovery "name of file".img
reboot and flash the ota from settings menu

If you have S-off, this OTA (nor any OTA I have ever heard of) won't take away your ability to root it again.
You will not loose root or s-off. It has been verified! this OTA is safe and was finished before we even had s-off. I do agree not to take an ota until the developers look at it to make sure you wont loose the ability to s-off or root. It is not the case here. If you are on the stock rom you will be fine.

it can be confusing for new users when seeing conflicting posts. nabbed is correct, though. from my reading it's confirmed by those who bring us s-off
never want to take OTA.. it can be pulled and flashed.. no reason to risk losing s-off permanently. and yes it is very possible from an OTA

From a theoretical perspectives its possible for OTA remove S-off. However, as I said, this OTA will not take away S-Off. Keep in mind there are legit S-Off phones out there that would be ruined by such an OTA.
Also, I have never heard of that ever happening, i.e. an OTA S-on'ing a device. If you know this has happened before, please link me to a source.
As far as I know, no OTA has ever caused an S-On. Losing root yes, but that can be easily fixed if you have S-off.

Wasn't trying to call you out or anything, just pointing out conflicting information. As the majority are in the do not flash OTA group.
I will ask someone who works on S-OFF to confirm that this is actually something to worry about.

No worries. Didn't meant to sound mean or anything. I have heard the same thing. "Never flash an OTA, ever." ...And if you are S-on, that is true as the OTA could remove root and/or make it more difficult to root/S-off. However, I have never heard of an OTA turning an S-Off device back to S-off.
My question is a genuine one. Has anyone actually shown that at some point an OTA has S-on'ed a device?
After installing the OTA then flashing twrp again I lost root. No biggy just had to flash super su again. Im not one to contribute to placebo but the speed of this build is very noticeable. Just see how much quicker the multitasking button works.
Only thing I'm noticing is my gestures aren't working anymore hmmm....

Semi-bricked OPO, need help restoring

Hi everyone, I have a big problem. Recently I got the phone and decided to root it. I used this guide: http://forum.xda-developers.com/showthread.php?t=2788632
I successfully rooted 4.4.2. using TWRP method, no problem but I when I decide it to update to OTA XNPH30O - 4.4.4. after clicking install, it sends me back to TWRP recovery page and I never able to install the update. What I did next was probably what got me in this situation. I went to recovery page, I did both format data and advance wipe but turns out it didn't clean everything on the SD DIR. So now when I restart the system, it just hangs on the OPO page.
Please how do I restore to the original factory ROM so I can re-root it again. Currently I have only access to fastboot and TWRP recovery page. I'm very noob at this and the last thing I want is to messed up the bootloader so I need someone to guide me through it step by step.
Thank You

33R are suppose to be a stock ROM? i thought 22R was hmm.. either way I did fastboot recovery to 22R but now I seem to encounter new issue: can't download anything from google play store due to an "error retrieving info from server". I'm getting frustrated now, I have no idea what to do...
I guess I should root it all over again to gain access to TWRP and SuperSU but what's after that?

Please enlighten me about this, I just wish to be on 4.4.4 rooted that fixes the current battery drain issue. I just want to install a ROM that's the most stable currently and most people would recommend at the moment.

22R was an earlier build based on Android 4.4.2, 33R is the latest CM11S build based on Android 4.4.4. Following my guide will get your phone back to how it would be if brand new out-the-box (but it will wipe all data in the process)
Which is probably overkill. All he needs to do is flash a ROM.

True, but if the OP doesn't really know what they're doing going back to the start might be a good thing. Otherwise, this ZIP flashed in TWRP would do the job...

I did just that using fastboot, I flashed ROM XNPH33R which is supposedly 4.4.4 and I again rooted it afterward with TWRP/SuperSU method. But now I think I need to go through a checklist on why my battery still isn't doing good as many would say. I wouldn't consider it draining but it does go down quite fast when I put it to use. Evening idling for 8 hours the phone still drains about 20% when I woke up.

Well I did all that, now I'm on 33R and is rooted, is there anything I can do to help improve the battery life? I';m still experiencing a drain.
OK I might have found something to do with battery drain now since I have root access, sorry I'm too new to rooting at this moment but I learned that I suppose to get rid of bloatware from CM11 to increase battery duration. Now the question is, is there a thread in XDA going over a list of what I should uninstall/freeze?

Getting rid of bloat isn't really going to increase the duration of your battery. Finding which apps are driving your battery the most or causing wakelocks and then dealing with them by using something like Greenify will have a positive effect though.

It should install the OTA without unlocking the bootloader, but if that's failing then unlocking the bootloader is the best option. Why don't you want to? There's no benefit to keeping it locked, and no detriment to unlocking it.

the only different thing are those word are write In Chinese?
The Chinese version is missing one LTE band, but that's the only hardware difference.
So..if I flash custom ROM or kernel...will it bootloop ? Cause of different hardware from the other one.
and can yoh tell me the use of bootloader? If unlocked in this device... and is it safe for me to flash custom stuff in this china 's OPO?

Yes, as long as you're currently on the build that directly precedes the one that you're going to flash. They need to be flashed in order. For example, to go from 33R to 05Q it must be done in this order
33R > 38R > 44S > 05Q
You can't do this:
33R > 05Q

Can i go back to cm11s this way?

Hi! My question is lame, i know.. But here it goes anyway, i couldn't find a simple and direct answer..
Is less than a week that i have this phone, and i've been reading a lot of guides of how to rollback to cm11s.. the thing is i've flashed the latest CM12S signed zip ota through CM Recovery, everything is fine as i'm testing it right now..
My question is: if i want to go back to CM11S (in the case that i don't like CM12S or have some bugs), can i just wipe data / factory reset and cache in CM Recovery, and then flash the cm11s signed zip?
I haven't rooted or unlocked bootloader, is it relatively easy from what i read around here.. but i wondered if i had to go through all those steps (unlock bootloader, custom recovery, and then flash) or just doing the steps mentioned before will work just fine..
Is it better to fastboot flash or through custom recovery is fine also?
Thanks in advance!
PD: I'm also asking what do you think about some other 5.1.1 Lollipop ROM, custom kernel, etc.. I'm kind of a flashaholic and i would be able to install the custom recovery if would be really worth it
PD2: sorry for the bad english, i'm from argentina

Just unlock your bootloader now, the longer you leave it the more difficult it'll be to backup your internal storage beforehand. You should really have it unlocked anyway as insurance against anything going wrong with your phone. Once you have unlocked it you can flash TWRP recovery, then the correct procedure to go back to CM11S would be to perform a full wipe (system, data, cache, dalvik cache) and then just flash the zip. As far as custom ROMs for this device go, there are many excellent options to choose from that offer extra customisation that you won't find on the stock ROM.
Don't we have to flash the firmware prior to flashing back to CM11s to prevent a hardbrick? I'm looking into doing this as well, so I'm just asking for my own clarity.

Once you've flashed the ROM, please do share your results. I am still unsure if reverting from a Lollipop ROM to CM11S will cause issues with the radio and/or a softbrick of the device, as I've read that this "can" happen.

Reverting from Lollipop to KitKat won't brick your device, whoever said that is wrong, and would have caused a brick because they didn't know what they were doing. You do need to make sure you flash a KitKat modem though, otherwise you'll have issues with the prox sensor.

pixel 3 root and unlocked?

Hey everyone
I first time use Google phone.
This time I bought pixel 3.
I want to ask what will happen to I root and unlocked my phone?
Will it lose its warranty?
Or something can't work?
Because I take Sony phone before
If Sony's phone unlocked then it's camera can't work and lose warranty.
So I want to know what I will lose after unlocking?
Or just relock it and it's ok
Sorry my English is bad.
Root will not void warranty. To get root,. You need to unlock bootloader. Unlocking bootloader resets phone to fresh state. Do that prior to setup. Everything works like normal with root.

Do not relock your phone if it isn't 100 percent stock. You will probably brick it and won't be able to flash it. Why would you want to relock it afterwards?

Sorry I long time haven't do this.

The only issue with unlocked is that will break Google Pay if you use that. However, almost all custom kernels hide the unlock and Google Pay will be fine. Or if you root with Magisk that will also fix Google Pay
Yes, flash back to stock before you relock it.
Unlocking or relocking will wipe your data, there is no way around that.

1. Yes. Fastbooting the factory image will return you to the stock google kernel. Or, you can just fastboot the boot.img as well.
2. On some of the kernels you can, check with the kernel Dev first. It's always good practice to return to the stock kernel before flashing another custom one.
3. Nope. It's not even working on the P2XL on pie.

Once you extract the factory image, you will see another zip file that has the vendor, system, boot, and other images. The boot.img is the stock kernel and recovery combined.
