Ordered Asus Zenfone 2 and Received a rooted Device. Shall i Un-root?

Guys i recently ordered an Asus Zenfone 2 Deluxe from a Chinese retailer. Obviously because the phone was the Chinese or Taiwanese Version they rooted the device and installed a WW Firmware before shipping it to me. The Version i have is 2.19.40.18 but the battary life is really bad. I realised all this when i tried to search for firmware updates but there is no way to search from the settings menu and the OTA Solution doesn't seem to work because i don't get a notification to update.
ADB doesn't work either because the 3 PCS i installed all the necessary drivers on, i couldn't get them to correctly recognise the device.
Anyways, i just want to be able to update the device to the latest WW software version, i don't care about the root if i will loose it because i don't use the device as a superuser.
What do you advice?

Same situation here. I have the same software version (both on device and in recovery). I also want to update the sofware but OTA option is unavailable in the SOFTWARE INFORMATION MENU, I tried manually but it doesnt work. I dont even know the root method used by seller so I dont know how to unroot, neither will unroot make manual OTA possible.
Please help someone.

Had the same problem. I unrooted, flashed stock latest firmware and now I have system update option.
I used this threads for guide:

Help to unlock the bootloader

So I have been trying to install Cyanogenmod 14, but I am kind of new to this, so I will probably seem pretty stupid. I basically tried to install it but forgot to unlock my bootloader. It was messed up, but I got help to install 2.20.40.184, so it works again. Now, however, I still want to install cyanogenmod 14. Partly because I for some reason don't get the OTA updates (I live in Denmark, where the Zenfone 2 isn't sold, so that may be it), so I've been stuck on lollipop since I got the phone. I don't even get a software update section under settings. So after all this, I tried to unlock the bootloader with the official app that you can download from the Asus website, however, when I do that, I get an error message saying "This device model is not supported". So looking for manual ways to root, I only found one that works with marshmallow, and when I download a ROM for marshmallow, I don't get the notification about an available software update. I also cannot enter recovery mode.
Hope this made sense, and that I posted it in the right place. Thank you!

Look for raw file .196 LP from RealYoti on here
Flash it in boot loader, with AFTool
You may have a china firmware converted to WW.
Once you flash try unlock ..or update from sd card to M ...Check my signature for flashing in AFT , also clues in downgrade link for how to write M to be recognised after a reboot for updating
If not got Chinese original serial you should be fine
Then when upgraded to M , Modder tool should be ok for unlocking bl in M
Then you can install 14.1

Hi, thank you very much for your reply.
Should I flash the raw file .196 even though I am using .184 right now? And which of the links in your signature is for flashing with AFtool (and where do I get AFTool?)
I have no idea if I have a chinese firmware converted to WW. Sorry, I am new to this xD
Yes, I am planning to use the modder tool once I have managed to update to Marshmallow.
Thank you very much

[OTA][6.0] Marshmallow update available for OPPO F1s

I just now landed to this page and found official Marshmallow update for our oppo f1s
How to update?
*BACK UP YOUR DATA*
Just put the zip file in your sdcard and reboot to stock recovery and "apply update"
Warning : This update will factory reset your phone and wipe all data. I upgraded without backup and lost all my data!
Link to OTA:
http://downloads.oppo.com.s3.amazon.../A1601EX_11_OTA_001_all_201703281552_wipe.zip
The OTA is released for Australia but it worked on Indian and Phillipines phones. I have tested it on my phone.
EDIT: Seems there's a global version also http://downloads.oppo.com.s3.amazon...A1601EX_11_OTA_027_all_201701110933_local.zip
I haven't yet tested the global version.

No point in upgrading. There are no root options.

The update zip doesn't contain stock recovery, which means if you flash the OTA via TWRP [by modifying updater-script] you can update to MM and re-root from twrp.
I haven't tried it because twrp is not working on my phone for some strange reason. Probably because I have 4GB version

There seems to be a problem with the mirror server in Australia, which means I can't download it. I've contacted oppo and asked for a download link from another server

yes... clean flash is always a good choice.

Marshmallow suck oppo f1s , Not appearing notification on status bar , Internet isn't working well n it's slow ,

Can someone help me?
I have updated my F1s to marshmallow however, I am unable to get the latest monthly updates installed. I have tried downloading the latest update (A1601EX_11.A.38_20190328) and installing manually, however that results in an error and fails to update.
It seems the recent update is for the lollipop rom. I don't want to roll back to lollipop as I have seen major improvements to GPU performance and battery life since upgrading to marshmallow.
Is there a way to get the latest set of security patches for marshmallow?

Hi. Had to make an account to answer you lol.
For some reason, OPPO stopped supporting marshmallow on the countries it was implemented. Philippines, however, did not effected the idea and would say, if you ever ask them, that their team is working on it. It's just a bunch of rubbish, we both know they're too busy with their flagship phones. F1s has long been forgotten and the only latest marshmallow update you could find is here, I'm not sure though.

12.5 update on QGGMIXM

So, this may be a dumb question but I can't seem to find the answer anywhere. I have my phone for almost two years now, and it used to get the updates the right way, until the 12.0.7, then it just stopped getting any updates, when I checked it says "no updates avaliable".
Searching yesterday, I manage to update it to 12.0.8 by changing the device region to India, but it just stopped there, I can't update to 12.5 or further.
While searching i've seen that the devices different from QGGMIXM (which mine is), like RGGMIXM already got the updates.
I even tried to install the 12.5 update (for RGGMIXM) manually and it said it could not verify the update.
Is there any way to change QGGMIXM to RGGMIXM or to get the update without changing it? Any help are appreciated

1/ Just tried vpn, didn't work
2/ Neither downgrading or upgrading worked, downgrading says it's unable to downgrade and tried to upgrade says it couldn't verify the update
3/ I haven't tried this yet, but I'm guessing it'll be the only way to update it.

Question Android 13 beta 3.3 won't install ...

Having issues installing beta 3.3 on my 6 pro.. did a factory reset then tried installing it. First time it took forever to install and phone rebooted and had missing operating system so I had to factory reset.. second time I got a failed to install message.. rebooted the phone and it said no operating system please visit this link from another device.. rebooted then phone worked normal.. what is going on here ? Phone is purchased from att, so idk if it's considered global version but whatever either way . Is there something stopping it from being installed? Was trying to do all this OTA.. thanks kinda new to it

I'm not sure if it being an att version has anything to do with it or not.. maybe the version google releases is only working on unlocked global models?? Someone shine some light on this..

You can use https://flash.android.com/ to flash with a computer.

So why would the flash tool work but not the ota method ?? Really curious cause when the official comes out hopefully I can flash that ota without any issues.. right now I opted out of the beta cause I really want the ota method to work and it doesn't ..

Can someone tell me why the ota wouldn't install ? Installed it the way I installed any other update on the phone through check for updates.. Id rather get ota working vs hassling with a computer to install it. That can mess things up if done wrong .

Is it failing to ota install the beta cause of a locked bootloader ? It does fine with install ota security patches on Android 12. Trying to install 13 ota on the phone itself fails.. I don't see why that would be though ?

@Redbeardkevv Welcome to XDA. Instead of posting multiple times in a row, please use the Edit button to edit your post and just add to it, in the future.
Official Google Android Flash Tool (OEM Unlocking needs to be toggled on - you may not have to manually unlock the bootloader - the "site" will do that on its own)
^ That Google site has saved many users on XDA. It has revived or corrected a mistake on their devices (mine too, once) when even flashing the full factory image didn't fix the problem. I have no idea what exactly it does that manually flashing doesn't. I normally use the full factory image zip, and that alone sometimes fixes issues that users have when they have issues flashing via the OTA method.

Oem unlocking toggled on isn't an option on this phone , purchased at att . I'll just wait till they release the official ota. But what would of been holding it up and making the installs corrupt??

If I remember correctly from other AT&T variant Pixel 6 Pro users in this section, once you pay off the phone and/or own the phone for long enough, AT&T should carrier unlock the phone, and that will likely make it so that you can OEM Unlocking and unlock the bootloader. (this also applies to T-Mobile, but does not apply to Verizon)

Well it's a far ways from being paid off I'll just add that .. what are my flashing options ? Also why would a security patch install just fine, then I enroll into beta ,try to install it, and bam it won't install and is corrupt install. Just doesn't seem right to me.. should I just wait until official release early August and then the OTA install from phone will work ?

Why would a security patch install without any issue , but I go to install this beta 13 and it fails and is corrupt . Same method as installing a security patch , only difference is beta won't install . Will it install correctly OTA when they release the final version in August ???

Firstly, unlocked bootloader is required to flash custom or beta firmware. While you can sideload OTA packages on a locked bootloader, I would highly recommend against doing so as you may end up with no way to recover your device.
When installing a beta, it is generally best to wipe and perform a clean flash. OTA is not recommended because beta software by nature is not yet suitable for public release, and may not appropriately handle everything correctly coming from older firmware.
As has been mentioned before, I recommend you use the Android Flash Tool to flash the beta. To ensure you have a fresh start, tick the Wipe device and Force flash all partitions boxes. Do not re-lock the bootloader.

So in short, wait for the official ota to roll out in August and install from phone then?? Cause I won't be able to unlock bootloader , phones not paid off... Would this explain why it's failing to install an beta from within the phone itself cause the bootloader's locked? So I have to wait for official ota rollout like I said earlier ??

Most likely. I doubt the beta will pass signature verification until it is updated to public release.

So not passing signature verification would be the reason it won't install ( ota ) most likely ? I'm just confused why a patch will install ota but the beta cannot .. must have something to do with bootloader being locked and it not being an official verified release or something

Just curious

Yes, you need the bootloader unlocked. So you cannot use those builds - only officially released OS builds.

It's a beta, so there will be issues for sure (but your last comment said you are getting an error [device is corrupt] that was common a few months ago so read on). You don't need to have an unlocked bootloader to enroll in the beta. Tons of users on Verizon and AT&T with a locked BL have installed the beta. Most are fine, some have had issues.
I wouldn't install a Beta on a locked BL. Why risk it? If something goes wrong, you'll need to get a warranty replacement. Seems like such a hassle.
For your issue, since you said you're getting a device corrupt message. This message is caused by q few different things (there's a thread on here about it). To fix it, users needed to do a factory reset in recovery mode. If you really wanted to try installing the beta (and you understand the risks), you'd probably need to: go to recovery mode and perform a wipe/factory reset.
From there, you could install the latest stable ota (via recovery mode) then see if the beta will update for you (via beta enrollment like you are trying to do), or directly flash the beta ota (link below). I'm just not sure if you can flash a beta ota image, over a stable build. I haven't tried it but according to xda, you can be on Android 12, and flash the Beta 13 ota (instructions found here).
There's two ways to flash an Android image: ota builds via recovery mode (doesn't require BL unlock) and factory image via fastboot which can be done manually or using Google's web flash tool (flash.android.com) - both if these require BL unlock.
You can find all the latest image downloads here. Google strongly recommends to flash the beta with an unlocked bootloader using their flash web tool. It's a beta so I would stay away until you can unlock your bootloader. Don't risk it. But I still think it might be a good idea for you to eventually perform a factory reset from recovery mode, since you are seeing the device is corrupt error message.

Had same problem, tried installing it twice and gave up
