Brand New OnePlus One rooted and with adware etc
I am a very newbie to not all but many of the particular issues in this post so would be grateful of any newbie taylored advice.
Background:
==============
I purchased a Oneplus one recently, stocked and fulfilled by amazon with amazon returns policy but seller was a chineese company.
It was advertised as 100% Original Oneplus One New Cell Phone
The phone arraived and appeared to already be rooted
evidence:
Barclays App says it is rooted and won't run. It ran fine on my Nexus 4
I can connect via adb and set to su straight away
The phone appeared to have arrived with significant malware / adware with popups and auto launch ad in browser pages and bloteware / PUPS(?), and other issues. After a great deal of research checking notifications and trial and error I disabled the following, some via settings\apps some via adb, pm ... disable ...
2048 (com.digiplex.game)
App Manager (com.shyz.steward)
Browser (com.android.browser)
Caller ID (com.android.tools.callassistant)
Clean Master (com.cleanmaster.mguard)
Cool Browser (com.cool.coolbrowser)
DU Speed Booster (com.dianxinos.optimizer.duplay)
Magic Photo (cn.dotui.magicphoto)
Videos (com.haolianluo.video)
and disabled gestures due to torch issues
The phone now seems quite stable.
I installed MalwareBytes, however None of the items it identifies is it able to disable/uninstall I set it not to scan automatically but it continues to tell me I have not responded to its list of issues, but I have responded by selected them, but on selection it tries to uninstall them but fails.
I was able to disable one of them via adb because it provided the package name for that one but:
CallerID.apk (disabled in settings\apps)
coolbrowser.apk (disabled in settings\apps)
201507140923731g.apk
AppStore.apk
I do not know how to uninstall (or disable at least on 2 of them) and I do not know how to refer to them from package manager because I don't have the package name.
Key Questions:
================
I am familiar with much of software engineering and programming but not with mobile phone OS / disk / memory / file system, etc. I am having a lot of difficulty getting to grips with the vocabulary, definitions and terminology depending what you read.
- Some say OnePlus from factory comes with cyanogenmod but is not rooted
- So one wonders how my phone go to be rooted if the seller is a retailer
- Some say if the phone is rooted the warentee is invalidated. What do you think?
- WhatsApp says the phone has a custom rom and watsapp may not work properly with a custom rom
It is very difficult to get to the bottom of exactly what the difference is between a stock rom
and a custom rom. Some seem to be saying cyanogenmod is a custom rom, but then others say what
comes on the phone from the mobile manufacturer is a stock rom, eg HT Sense or in the case of
OnePlus, cyanogenmod! Is it only a custom rom if it is somehow NOT proven to be a
custom rom validated by the mobile manufacturer in factory (i.e. stock rom)?
- Some say having a custom rom invalidates warrantee, is this right?
- How do i prove that the rooting and the custom rom were not introduced by me?
- I have thought about factory reset, but I cannot manage to find anything that tells
me what this actually means and does, only how to do it.
- does a factory reset actually do what it suggests. I have read that factory reset does
not involve going to the manufacturers site and obtaining an appropriate image and flashing
it to the phone so I do not quite understand how else it could guarantee it
- If a factory reset will just make it like it was when I received it then that I do not want.
- Can I and ought I to flash a fresh image on the phone to get it like it WOULD HAVE been
had I bought it from OnePlus factory on invite and not through a mediator
- Finally. There is a notification "System Update is ready" . When I select this it appears
to download something (next version of cyanogenmod I guess though I don't recognise the version
number against any cyanogenmod versions) then it restarts and goes to a recovery app.
At this stage it is not completely intuitive what one should do and it seems to want you
to navigate to a location.
Now, I think I could probably figure this out with some reading but two things come to mind:
1) Presumably for a from factory OnePlus phone this kind of ambiguous unintuitive update
process would not be going on for people who just bought their phone and knew nothing
so it suggests the phone is in a different state to that. I also read you need root
already to install a (good) recovery app.
2) I am loath to do this update since it is not clear whether the update is this retailers
system update and will reintroduce all that I have disabled to create stability. Therefore
up to now I have always selected just do nothing and reboot. I favor stability over
features.
I am kind of inclined now I have managed to get it stable to just stick with it as it is and just use it without any further updates / resets / flashes and without returning it, but...
Sorry to ask all these questions. I would be grateful of any advice. Can be given with the assumption that I understand foundational general stuff ram, rom (though this word seems to be used differently to what I'm used to), flash, image, partition etc, but not that I actually know all about how the android/cyanogenmod platform is laid out and behaves as an installation.
Thank you.
Hi, All Oneplus One phones comes with CyanogenMod without rooted. One must Unlock bootloader and Flash custom recovery and Flash SuperSu to get root access.
Yours already says rooted means either you bought the used phone or refurbished. However even when a phone is refurbished OnePlus company locks it and make it unrooted.
OnePlus Phones warranty doesn't get over bu rooting. OnePlus actually supports rooting. Warranty becomes void when you do something blunder while flashing and your devices becomes dead aka bricked.
What I am suspecting is the chinese seller bought new OnePlus and Installed different ROM as the chinese OPO comes with ColorOS which doesn't have PlayStore. Now in the procedure they introduced unwanted Adwares which may be Intentional or Unintentional.
Now you have 2 options.
Either ask Amazon for a refund.
Or if the time is passed then I suggest you to start fresh. If you have already custom recovery installed then go ahead and install fresh stock CyanogenMod ROM from xda.

Hi Abhinav_Rakesh,
Thank you so much for your response, I really appreciate your advice. I think I understood most of what you said, generally but I am still a bit unclear on some points:
Is there any way to tell if the phone is refurbished. I would rather it were new even if they have installed a different rom.
What do you mean by "time is passed" I have only had the phone a few days. I am in a quandary whether to return it or not, whether amazon will believe it was not me who rooted it and whether I will be able to get another one that is not just the same as this one anyway since you cannot get them direct from OnePlus any more.
I saw some kind of recovery screen over one reboot but did not do the install. How do I know if this is the "custom recovery" you describe, if it is not how do I obtain / get to "custom recover"?
Can you direct me to a script that shows me how to "install fresh stock CyanogenMod ROM from xda"? Will that completely blank out everything that the chineese company may have done on the phone, or might some stuff still be left behind? Is there a risk to that process, given that I at least have a fairly stable phone now? Will it include or do I have to get separately "PlayStore" so I can download my usual apps?
Thank you again, I really appreciate it?
i suggest you to start from fresh, since obviously your OPO is not in stock state and has been tampered with..
the (general) steps to make the OPO like new are as follows..
(1) connect it to a pc via usb cable
(2) in command prompt, issue "adb reboot bootloader" (and wait for it to boot into bootloader/fastboot mode)
(3) issue "fastboot oem unlock" (to unlock the bootloader.. all data will be wiped but the warranty is not voided)
(4) issue "fastboot flash recovery custom_recovery.img" (replace "custom_recovery.img" with the actual recovery file name)
(5) power off mobile and disconnect from pc
(6) press power button together with volume down button (to boot into custom recovery we just flashed)
(7) while in recovery, install rom image (which should be put in the internal storage beforehand)
(8) reboot to enjoy the reborn mobile
to be able the complete the above steps, you need to get some files in advance:
- adb.exe/fastboot.exe (which you should already have since you could do adb)
- custom recovery (TWRP suggested.. get the image for OPO, whose codename is bacon, at http://twrp.me/ ), and put it in your pc..
- stock or custom rom (the stock for OPO is cyanogenmod, and there is also a OnePlus provided OxygenOS rom.. go to respective sites to get a copy), and put it into the mobile's internal storage..
mind you that by doing so (the fastboot oem unlock step) all your mobile's data will be wiped..
@hardya Hi .. You can follow this link to restore your phone according to OnePlus Standards. This will remove all that chinese ads and all and will make it fresh.

There is a little misconception about what cyanogenmod is.
The offical Oneplus One comes preinstalled with CyanogenOS (or CM12S), which is derived from Cyanogenmod. It get's a bit complicated. Cyanogen is a company founded by the lead programmer of Cyanogenmod. CyanogenOS is a commercial product, that is licensed to phone manufactures.
Cyanogenmod is the codebase for CyanogenOS. CyanogenOS adds some functionalities that are not present in the community maintained Cyanogenmod. (e.g. a alternate dialing app, theme store, etc.)
The offical Oneplus One comes NON-rooted. You need to manually enable root.
Please keep in mind that it gets REALLY complicated from this point!
The Oneplus One debuted with CM11S (CyanogenOS, the commercial version of Cyanogenmod). Cyanogen (the company) promised users 2 years of support and updates for the owners on the Oneplus One. But Oneplus and Cyanogen had some major issues that resulted in ending the partnership.
Oneplus had to offer an alternative Android Firmware for their upcoming phone Oneplus Two. So they did another android version called OxygenOS. This was installed onto all Oneplus One phones from a certain date onward!
THIS is the OFFICAL Android Software Version for your Oneplus One!!!
See: https://oneplus.net/de/support/answer/how-can-i-download-oxygen-os
I would strongly recommend to install OxygenOS, as it is the easiest way of experience the phone as Oneplus intended it to be.
Most tutorials on here are a little bit older so they are offering guides which mention either CM11S, CM12S, Cyanogenmod or OxygenOS. (or if you are more familiar with other customroms, whatever you'd like to install! But this is something you should look into, when you are more familiar with what costumroms are and what they do! There are so many excellent guides on here, which i'd recommend you to read sometime!)
- So one wonders how my phone go to be rooted if the seller is a retailer
Click to expand...
Click to collapse
He rooted it either manually or used an android version (e.g. something downloaded off XDA or got one from some developer). Such versions are often called Customroms.
Also note, that there are no official retailers of Oneplus phones. They are officially offered from the website only. However, there are some shops in China, that offer Oneplus phones.
- Some say if the phone is rooted the warentee is invalidated. What do you think?
Click to expand...
Click to collapse
Most phone manufactures actually tell you that your warranty is void when rooting your phone.
Oneplus however is very, very supportive when it comes to rooting!
And of course installing other Android Versions and Roms!
See: https://oneplus.net/de/support/answer/will-rooting-or-unlocking-the-bootloader-void-my-warranty
- WhatsApp says the phone has a custom rom and watsapp may not work properly with a custom rom
It is very difficult to get to the bottom of exactly what the difference is between a stock rom
and a custom rom. Some seem to be saying cyanogenmod is a custom rom, but then others say what
comes on the phone from the mobile manufacturer is a stock rom, eg HT Sense or in the case of
OnePlus, cyanogenmod! Is it only a custom rom if it is somehow NOT proven to be a
custom rom validated by the mobile manufacturer in factory (i.e. stock rom)?
Click to expand...
Click to collapse
Cyanogenmod is indeed a custom rom. (or sometimes aftermarket firmware)
See: https://en.wikipedia.org/wiki/CyanogenMod
A stock rom is the firmware that is installed by the manufacturer. (in your case: CyanogenOS, called CM12S. the 12 stands for the version number of Cyanogenmod. 12 = Android 5, 13 will be Android 6. There was a CM11S version, when the phone debuted last year.). The S marks it as CyanogenOS, the commercial product. So CM12 would be the community maintained Cyanogenmod. CM12S the product by the company Cyanogen. As said before, it's a bit complicated, as the current OFFICIAL rom is OxygenOS
Your findings of software not present in the official stock Oneplus One rom (which is either CM12S or OxygenOS), suggests your software on the phone is actually a unofficial costum rom.
- Some say having a custom rom invalidates warrantee, is this right?
Click to expand...
Click to collapse
See the answer to the rooting question. Almost all major phone manufactures void your warranty if you flash a custom rom. As it involves tampering with system files and most people are not very knowledgeable when it comes to "computery things". It's just a security measure, so that people won't sue the company when something bad happens (most likely deleting precious pictures, etc.)
Oneplus actually encourages people to try other roms. This made the Oneplus One a very popular phone for tinkerers and as you can see on this forum there are a lot of custom roms you can choose from.
- How do i prove that the rooting and the custom rom were not introduced by me?
Click to expand...
Click to collapse
If the seller was not so careful, there will be a notice, which can be read by software programs available here on XDA, that say how many times a custom rom was installed.
However, i think your main concern is, that you wouldn't be able to get support form Oneplus, because you think your warranty is not valid anymore. As said above, your concerns are not that problematic. Especially as you seem to be knowledgeable enough to actually fix things on your own!
- I have thought about factory reset, but I cannot manage to find anything that tells
me what this actually means and does, only how to do it.
Click to expand...

A factory reset will delete all your apps and reset the system to the state"it came out of the factory". So when you start up your phone, you need to set it up again. Enter your name, configure your WiFi settings, install your favorite apps.
However. Your photos and your music files will not be deleted! Be careful though. Resetting your system will delete your app settings. I just want to point that out, because the first time a did a factory reset and reinstalled everything i thought i lost all my Whatsapp photos. They were there in the Picture folder, but weren't linked to the images in my chat window! This is a bit complicated, but can be solved quite easily, if you know what your doing (backing up your apps with certain programs, e.g. Titanium Backup).
- does a factory reset actually do what it suggests. I have read that factory reset does
not involve going to the manufacturers site and obtaining an appropriate image and flashing
it to the phone so I do not quite understand how else it could guarantee it

Factory reset is a internal function of your phone (to be precise of your phones recovery!)
However, as most people said and your suspected is: Your phone does not run the official factory image, provided by Oneplus (or Cynaogen).
The official software can be obtained from

- If a factory reset will just make it like it was when I received it then that I do not want.
Click to expand...
Click to collapse
Yes it will most likely to what you fear. It depends on what the retailer did. Most costum roms include software in their phones, that will be installed again with a factory reset. If your seller did install the programs AFTER the phones original state (e.g installing it from an appstore or from the APK's (Androids Software Packages)) they won't be present!
- Can I and ought I to flash a fresh image on the phone to get it like it WOULD HAVE been
had I bought it from OnePlus factory on invite and not through a mediator
Click to expand...
Click to collapse
Absolutely! I'd recommend you to flash a new image to your phone!
There are a lot of great programs here on XDA that offer easy and intuitive options of doing that, without even knowing anything about flashing programs! Try to take a look around and see what you can make of it.
I personally think they are great, but can be dangerous if you didn't read the proper instructions. I'm just saying, as they often delete EVERYTHING on your phone. So whatever you do to your phone, backup everything before!!!
But these simple programs are what you are looking for. They will install the firmware (Cyanogenmod or OxygenOS) that are bloatfree and as the Oneplus intended them to be.
- Finally. There is a notification "System Update is ready" . When I select this it appears
to download something (next version of cyanogenmod I guess though I don't recognise the version
number against any cyanogenmod versions) then it restarts and goes to a recovery app.
At this stage it is not completely intuitive what one should do and it seems to want you
to navigate to a location.

This further suggests, that your are not running an official version. The official update process is fully automated and doesn't need any user intervention! From your description it doesn't do anything and you are stuck in recovery, that is waiting for user input. This is not the case with proper official roms!
Now, I think I could probably figure this out with some reading but two things come to mind:
1) Presumably for a from factory OnePlus phone this kind of ambiguous unintuitive update
process would not be going on for people who just bought their phone and knew nothing
so it suggests the phone is in a different state to that.

Absolutely correct! See above.
I also read you need root
already to install a (good) recovery app.
Click to expand...
Click to collapse
You do not need root to install a recovery. This is a bit complicated, as there are some misconceptions about what is what. You need to "unlock" your phone to install another recovery. This is not rooting, but is also restricted by many manufacturers. But as with rooting, Oneplus is offering support on unlocking your phone and there are lots of guides on how to do it.
2) I am loath to do this update since it is not clear whether the update is this retailers
system update and will reintroduce all that I have disabled to create stability. Therefore
up to now I have always selected just do nothing and reboot. I favor stability over
features.

Wise decision.
I am kind of inclined now I have managed to get it stable to just stick with it as it is and just use it without any further updates / resets / flashes and without returning it, but...
Click to expand...

I would strongly recommend to NOT leave it this way! As you yourself found out, there are chances that there are programs on the phone, that are not to be supposed to be there. I'm not saying that there is spyware on your phone, but it is most likely that there could be malicious code running in the background of your phone. I would strongly recommend NOT to use apps, that need sensitive information of yourself!
Try to look for guides and tutorials here on XDA and just install CM12S, Cyanogenmod or even better OxygenOS, the official ROM from Oneplus! OxygenOS is not everyone's favorite choice, but that way you can be sure, that NOTHING fishy is going on on your phone!
There is an easy app available from the offical oneplus site!
https://oneplus.net/de/support/answer/how-can-i-download-oxygen-os
Or use the app that is mentioned in the post above! Will to the same thing!
Use the instructions on there and you are much safer on using your phone than you are in the present state!
BUT PLEASE, PLEASE DO A BACKUP OF YOUR DATA! I mean, your photos, contacts and everything important before doing anything to your phone. I'm just stressing that out, as so many people complain afterwards that they lost everything, etc.! Not just because the process they did was unsafe, but becaus the didn't properly read the instructions that tell people that they should make a backup, BEFORE tampering the system. It says factory RESET, so it should be clear, that everything will be reset!
I'd suggest you return it and get one through official channels. Official OnePlus devices can only be purchased through the OnePlus store.
I'd suggest you to read this story:

Ctuiku,
Sorry I wasn't able to respond sooner. I really do appreciate your very clear and detailed response and it's care to address each point very clearly and to make clear distinctions between similar things gives me significant confidence in its accuracy.
I must say I appreciate the significant amount of time you have taken and I do hope that at least some of your responses were cut and pasted from text you had already written else where.
I think I may have a number of minor follow up questions, but for now I shall digest your advice and decide on my plan of action.
Thank you again for being so helpful and understanding.
Andrew
I actually didn't read much of it and the comments, but I'd suggest you to unlock the bootloader, flash TWRP, take a backup, wipe everything(not the internal storage of course) , and perform a clean flash of CM13.0 by sultanxda. It's the smoothest and the most stable ROM out there.
Well, that was all in brief. You gotta read(and understand) and perform. It's fun, just like programming. Keep flashing!
~noob (you gotta start from somewhere)

Thank you again for all your help. Sorry for the delay in responding been busy with other things and also since had some time to digest...

a lot of what I read, like on the oneplus site or the way links are named seems to suggest that OxygenOS is just for OnePlus Two. I believe that OnePlus One moved to OxygenOS at some point, but I don't want to apply an OS version to a device that is under resourced. Is there a version of OxygenOS that the OnePlus One should not go beyond.

Thank you so much for your advice I really do appreciate the time you took to help me. Sorry for the delay in responding. Difficult circumstances.
regarding your point (7)
(7) while in recovery, install rom image (which should be put in the internal storage beforehand)
Click to expand...

- I wonder if you would mind indicating where beforehand in this list putting the rom image in the internal storage ought to occurr?
- Also, so sorry, but I wonder would you mind elaberating just a little on how to put the rom image in the internal storage?
Regarding the files, I am happy with adb.exe, fastboot.exe, TWRP.
However I understand that the genuineness of OxygenOS images are not provided by OnePlus, is this right?
_forums_oneplus_net_threads_mirrors-for-official-oxygen-os-roms-and-ota-updates_387615
How do confirm the genuineness of OxygenOS images?
Is it a kind of hierarchy of trust, i.e. n users use and recommend this location for the images.
Or is there some kind of standard hash for the images that is published on secure OnePlus site?
I have similar issue / understanding issue with CM12S
It would appear after roaming around forums etc that the official Cyanogen OS (not mod/custom) are located below here _builds_cyngn_com_ but the site itself seems to have no web pages I visit cyngn.com_get-cyanogen-os but can find no page with a list of rom images and their corresponding dates, attributes and inclusions etc.
I hear that some versions of CM12S do not support 64GB (as per my OPO) but I seem to have no clear certified single source way to know exactly the name/url of the CM12S I should get.
I am probably misunderstanding the philosophy behind things, but it seems if anyone can do anything with the source you would think that OnePlus would into the bargin also provide users (of which there will be a variety) a "sure fire" way to get their (grey market?) phone to (original) factory standard. They still apparently cover it for warentee, so...
Many thanks
P.S. How do I get your XDA user name to appear as a link?
Hi there,
My phone has android 6.0.1 and i want it downgraded to android lollipop because ive got problems with android 6.0.1.
Im a total noob with all this stuff, so can someone please advise step by step how i can do this? I have the MOTO G 3rd Gen, SKU is "XT1541", Ram is 1GB and ROM 8GB. My current system version is 24.61.55.osprey_reteu.reteu.en.EU reteu. Build number is MPI24. 107-55. This phone will accept any phone network. Can someone please help? thanks in advance!
There are multiple threads discussing downgrading, it can be done if your device has the bootloader unlocked (which wipes data and voids the warranty)... There are some inherent dangers in doing so, some immediate and some long-term dealing with future updates which have the potential to brick the device.
What are the issues you are having, many times it is better to solve those then to downgrade.

Some apps wont run well on android 6.0.1 such as facebook etc (personal and buisness use) and my phone generally ran better with the previous android version. The phone does not have a warranty on it anyway so that does not matter. Trust me, it really cudnt be much worse than it is atm, ive factory reset it and its just not up to standard as it was with android 5. I did have android 6.0 which i didnt like and then i got 6.0.1, which was putting ice on the cake, (in a bad way!). I am 1000% sure i want to downgrade my device. Can you help?

Not much to it... Unlock the bootloader, factory reset, then use the lollipop factory image from the factory images thread, gpt.bin will fail, just continue to flash everything all the way through. Follow the instructions in how to flash factory images, it's all done in fastboot.

No offense, but this is not something to be taken lightly... there are many steps.
First, backup all your data... it will be lost.
Start by reading the first few posts in this thread... This will give the basics of what is needed to be done, what tools you need, how to do it, and the factory firmware images (you will need the correct one for your device, all the ones available are in this thread.
Next, read the first two posts in this thread... this is the instructions in detail of exactly how to flash a firmware image. Pay attention to the warnings and follow the linked threads with more information and make sure you understand all of it.
Once you have read and understand this part, you need to get fastboot working... this tool is essential to making all this work. Both of the threads I mentioned above have links to the drivers and Minimal ADB & Fastboot you will need. Install them and make sure they are working.
Now you can unlock the bootloader, this will wipe all data on your device. The instructions and process are done directly with Moto here.
Once you have unlocked the bootloader, reboot and start the bootloader and follow the instructions in the threads above, noting that the part where enter the command "fastboot flash partition gpt.bin" will likely fail because you are downgrading, but no other pieces should fail, if they do enter them again (radios are known to need to be done 2-3 times sometimes before taking), and continue all the way to the end. Pay attention to the number of sparcechunks in your image, it can will vary and you need to flash all pieces in order for your device, there could be anywhere from 5-9 pieces.
Keep a log of everything, it is much easier to tell what happened if something goes wrong by looking at the terminal log (scroll back of the terminal window) than just guessing.
TBH... I am not endorsing this method, but it generally does work, and although it is difficult to brick the Moto G 2015 it is not impossible. After you are done, you will need to root the device and freeze the updater service so you are not constantly prompted to update, and taking an OTA update can be problematic since your bootloader and/or partition table will not match the rest of the ROM correctly.
Personally I think since you have to unlock the bootloader anyway, you are probably better off just looking for a custom ROM like CM13, Resurrection Remix, or something like that since there are lots of rock solid Marshmallow aftermarket ROMs. Or if you are dead set on Lollipop, using CyanogenMod 12.1 instead of downgrading.
I know there is a downgrade utility out there, and not to take away from the developers work but I would suggest avoiding it.
I'm fed up with people on this forum. I keep trying to engage people in a discussion, a conversation to explain some things to me and No one seems willing. It's like there are No Rooting gurus that can answer my simple questions. On a forum full of Android developers, I'm very disappointed, I thought i'd get tons of help. If you read this, Please consider staying to have a discussion/conversation with me.
Preface to The Discussion:
I have used both Android and Linux in the past, I know what Super User is, I use it in Zorin 12 Linux and own a rooted (kingroot) android tablet. I am trying to get information on rooting my Figo Atrium phone by trying to understand Rooting better in general. perhaps this discussion will make since to you and together you can help me find a way to root my phone - But I Must have a back and forth or I'll never understand this. - I know there are many exploits to root a phone used by tools like kingroot. I know these exploits are many and varied depending on your phone's CPU architecture, and software and not all root tools with work with my device. . I know the bootloader has to be unlocked and one must have USB Debugging enabled in Developer Options. I know some phone manufacturers make tools that help you root your phone (MTK Droid Tools) So far, none of these tools can root my phone.
Let's Start The Discussion Here:
I was able to not root but my Upgrade my phone from Lollipop to Marshmallow. I did this using SP Flash Tool and these instructions (which were badly translated and which as you can see by the comments in the video, I had to correct due to bad translation) See this video and comments by me to understand. https://www.youtube.com/watch?v=EEIJM2YjNzE - I used SP Flash Tool and a Rom Figo provided. After I figured out the botched instructions, I was able to upgrade my device with no problems.
Question 1: Isn't this essentially the same process that is used for Rooting? It proves my bootloader is unlocked and the phone does have the ability to flash a new Rom. <- Based on That, doesn't it seem to you that my phone would be in fact Rootable?
If you think so, tell me why, if you think Not, tell me why.
Question 2: If you think So, then: Someone suggested to me that using a tool like Magisk or SuperSU may be able to root my device. Does this seem likely to you based on what I've told you so far? No one in the SuperSU sub forum can answer this question.
If you think No, then we'll discuss this more. I'll wait for your replies. Thank you.
Rooting is, simply said, placing a 'su' binary in the system folder. SU means switch user, when you give that command you're instructing Android to give you root user privileage. OEM's don't want that to happen so they won't include it in their ROMs. Tools like supersu are made to copy that 'su' file to the system partition. There are a lot of ways to explain this, I'm just giving you something quick and easy to understand.
Now regarding your questions;
1) Flashing anything requires the bootloader to be unlocked on most phones. BUT MTK phones don't. (Except some HTC phones). SP Flash Tool can flash any partition without needing to unlock. It's dangerous security wise, but this means its also easier to root.
Infact all MTK phones are rootable. So don't worry about that.
2) How to root? The best way to root is with supersu. (You can also try magisk if you want to use Android Pay).
You need a custom recovery like TWRP first.
I found one here which is for your same CPU. https://www.needrom.com/download/twrp-recovery-13/
^I am just giving you a link to recovery which uses the same CPU so It may or may not work. PLEASE take a backup of your original recovery before doing anything.
Now download SuperSU zip file from here https://s3-us-west-2.amazonaws.com/supersu/download/zip/SuperSU-v2.82-201705271822.zip
Don't open it, just keep it in your sd card.
Flash the recovery using SP Flash Tool (check only the recovery box and select this file). Now unplug the phone and press Volume Up+Power Button to boot into recovery.
Then if it says swipe to allow modifications, swipe.
Now goto Install->Select the Supersu.zip file you downloaded->Swipe and reboot.
That's it! You're rooted!
Thanks.. again, you've answered things others couldn't. Much appreciated.
You say, " You need a custom recovery like TWRP first.
I found one here which is for your same CPU. https://www.needrom.com/download/twrp-recovery-13/
^I am just giving you a link to recovery which uses the same CPU so It may or may not work. PLEASE take a backup of your original recovery before doing anything."
Lets say Twrp doesn't work. What is this for, just to re-flash your original rom in case twrp fails at making a backup? ( I assume the tool makes your installed rom flashable in case the root doesn't work and you need to revert back to your original system) I have the SP Tool and the Rom for Marshmallow that works with my device from Figo. Can I use that if Twrp fails - or am I not understanding what twrp is used for? Just checking before I start this. Otherwise, I'll try to follow your instructions to the letter and see what happens.
Still Looking ?
STILL Looking? IF so, a few thoughts .... It is a nice phone for the price. The newer version eventually coming out looks even nicer, and for now, it is still my backup phone to my Figo Gravity. Discovered Figos when I got totally fed up with BLU phones.
ONE - If you have upgraded your Atrium to Marshmallow, as I did, none of the rooting methods that worked on Lollipop will work, so forget about them.
TWO - Down in Developer Settings you need to make sure OEM unlocking is allowed.
THREE - ASSUMING you have a TWRP build that will work, it is pretty simple. Take the ROM image that FIGO sent you and replace the "recovery.img" file with the TWRP (re-name it recovery.img and save the old one as recovery.old JUST IN CASE) file. It will be much larger than the factory ROM recovery image and that's fine. The scatter table, if you read hex addresses, provides for enough space to do this. Flash ONLY the recovery (TWRP) image, and be sure to DOWNLOAD ONLY with the SP FLASH tool. If uncertain, DO NOT PROCEED. It can be a real pain in the arse to re-do things if you accidentally format or upgrade things you didn't mean to. ASSUMING that worked, you can boot into TWRP by holding down the power / volume buttons (I assume you are familiar with this sequence).
FOUR - it is entirely possible that the next time you boot the thing normally, TWRP will be blown away. Happened to me a few times. There is some setting down in the boot image that causes this and I will have to dig up my notes to see exactly what the heck it was. It required taking apart the boot image - I used Carliv - fixing the one setting, and then re-packing and re-flashing it, BUT, you can ALWAYS keep replacing the TWRP image as needed. Inconvenient, but better than a sharp stick in the eye.
FIVE - when booted into TWRP, you should be able to flash SU, which will give you root, and it should STAY rooted after that unless and until you uninstall SU. FLASHIFY is STRONGLY recommended as a VERY useful app for rooted devices. TWRP, if you are unfamiliar with it, is SO MUCH MORE than just a recovery replacement. Handiest whole device backup there is. Has saved my bacon on several devices through numerous acts of personal stupidity. :crying:
SIX - IF ALL ELSE FAILS, you can ALWAYS revert to the factory image ROM. Just DOWNLOAD ONLY rather than Upgrade and DO NOT Format.
Hi Everyone,
Living in Japan, we have no official channel to purchase a OnePlus handset here.
Really wanted to get a OnePlus 7 Pro as I felt it is the best model on the market as of today.
Knowing that, I got mine on Amazon Japan from a HK online shop which had very good reputation.
Now, the problem is these phones always come already opened as they say they need to confirm operation before sending it.
I have been reading news and article about this where we see more third party companies flash their roms with malware/ransomeware already built in...
In these situation, the best way to clean the phone is to do a full re-install of the OS.
I did review a bunch of article on XDA and it seems that now, due to the A/B partition setup, we can't just use official OnePlus image to load from the fastboot easily.
We have to rely on community provided too and stock rom to be able to do so....
When I raised the question to OnePlus and Oneplus forums, they mentioned to me that installed the updated like here (Page: support.oneplus.com/app/answers/detail/a_id/4312/~/oxygen-os-for-oneplus-7-pro)would do the trick using the local update function.
What I was directed to do is use the recovery boot to delete system settings/cache and everything data user and then, run the local update. Doing so, that would do it while not using community tools.
Here are my questions and which I would hope to get your experience:
1 Is the process I did really does use a brand new clean OS and do not rely/integrate part of the OS that came with the handset originally (that was the target).
2 Is there a way for me using OnePlus only provided tools and image to fully delete the phone and install the OS (maybe I am thinking this too much like a PC which I have more experience with...)
3 The OS looks fine and no strange apps shows up at all but how can I be sure nothing dodgy is running? Is there tools I could use to confirm this?
Sorry if I sound paranoid. Ideally, I understand the best thing to do was to buy directly from Oneplus and work a way to have it shipped to Japan but thought it would be interesting for me to learn more about android.
With previous Oneplus, it was easier as they were provided this type of official file for recovery but they stopped...
Thank you again for your time and hopping to learn more about how new android setup works.
Is the bootloader locked? Is Widevine (Netflix HD) certification still there? You can check these things to see if the phone has been tampered with.

Good questions. Before you start, check the model number of your device through Settings > About. I'm assuming it's the international/global/unlocked version (GM1917).
With regard to question 1, a full build downloaded from the link you provided should contain every part of the OS, and flashing it through local update should overwrite anything that was there before. Before flashing, I would perform a full data wipe through recovery like you mentioned.
Q2: There is an MSM tool that will completely flash a system image for the OP7 Pro. I don't think they're generally intended for public use but they always get leaked anyways. They write an image (in the case of OnePlus, a .ops file) to the phone using a PC and USB connection. Here is a link to a thread which contains the MSM tool:
https://forum.xda-developers.com/oneplus-7-pro/how-to/guide-mega-unbrick-guide-hard-bricked-t3934659
Download the tool for the model of your phone (probably the international, firmware GM21AA), and extract its contents into a directory. In order for the tool to work, you need the OnePlus USB drivers installed on your PC. Plug the phone into your PC with it on, and enable USB file transfer. Open File Explorer and you should see a drive labeled "OnePlus drivers" or similar. Open it and run the driver setup executable file. You'll also need ADB to make your phone reboot into a mode that will allow the tool to perform its tasks. Here is a guide to installing ADB:
https://www.xda-developers.com/what-is-adb/
Once you've set that up, make sure the phone is plugged into the PC and the MSM tool is open. Make the phone boot into edl mode by typing
Code:
adb reboot edl
and once it says Connected next to a COM port in the tool, press start. Don't interrupt the process until it completes the download and the status message turns green. The phone should automatically reboot. This method is arguably more risky than using the local upgrade option, so do it at your own risk.
Q3: Make sure that OEM unlocking is turned off in developer settings and that the bootloader is locked (if the bootloader is unlocked, you'll see a yellow warning message after you power on the device from a power off state). Without an unlocked bootloader it would be pretty difficult to make any deep modifications to the device.
Hi @Zocker1304 and @TManchu,
Please let me thank you very much first for your kind and detailed reply, this is really welcome.
@Zocker1304:
I checked using the ADB/Fastboot connection that indeed, the Bootloader is locked so, that looks good.
Also installed (using a separate Google account) DRM Info app to confirm that the Widevine is properly installed and at L1 level which indeed again, looks good.
@TManchu
Thank you again for your very detailed reply! This was exactly what I needed as information.
I did already exactly as mentioned for the #1 so, it looks I should be good now with a proper rom from OnePlus (and did a full wipe in the Recovery boot mode)
For #2, I think I will skip that since as you rightly said, with #1, it should be fine so, prefer to keep with the recommended step.
For #3, we are covering what Zocker1304 mentioned too and I could confirm it.
My only concern about #3 was that you can actually relock the bootloader but (and please correct me If I am wrong), you can only do so if you are using stock OnePlus images (to date...seems like dev teams are working to have this changed? Bootloader locked with custom firmware?) which then means the image is safe.
I suppose the last item was my only open query for your thoughts but so far, the handset looks fine.
Thanks to you and the community, I have learned about the A/B partition scheme, msm tool, Fastboot/Recovery mode and Bootloader and ADB tools.
It is always good to learn more about the tech we use (especially phones, we have so many sensitive information stored into them today).
Not being careful could potentially means quite a lot of troubles down the road with Ransomeware/data leak tools.
Of course again, I could have simply purchased a JP phone from a brick and mortar shop next to my place and be fine with it. :silly:

No problem! I’ve just done some reading and from what I understand, re-locking the bootloader on anything other than a completely stock ROM will result in a bricked phone. I believe this is due to the way Android handles data encryption. If what you’ve heard is true, being able to lock your bootloader on a custom ROM would be great for device security. However, should something go wrong with the ROM having a locked bootloader might make it more difficult to fix.
I know that there are ways to sign system and boot images so that you can lock the bootloader with them installed, but I think that would still show a warning though I'm not sure.
Anyways, if all the build dates and numbers in the system info are correct, the firmware should be stock and as long as the bootloader is locked too, I don't believe you can tamper with that.
Hi Gents,
Thank you very much for the answer to the thread and much appreciated.
Apologies for not getting back to you all earlier as yesterday was family day...haha!
Well, since things looked good on the OS and the build, I went ahead and started to use the phone properly setting up my accounts. It did give me some incentive to get all my sensitive accounts setup with 2FA so that in case I get hacked with my passwords in the future...they would still need the 2fa (using Google Authenticator).
I did check also all system apps/running process and didn't see anything shady.
Just for reference, here were the type of articles I was refering too for the OS being plagued with malware even out of the box:
Page_theverge.com/2019/6/6/18655755/google-android-malware-triada-ota-rom-ads-spam-oem (sorry gents, new account, cannot put links yet)
However here, it seems it is due to lax review from the maker to third party tools which were including malware...
To have the same level on the oneplus I bought from the HK shop, they would have needed access to OnePlus Dev team to inject the malware in official image (knowing anyway I have re-installed a new image from the local update).
Otherwise, I was reading on the web about the fact to relock the bootloader with a custom roam and there seems to have a lot of messages but not concrete steps. It seems it depends a lot on phone model and brand.
When you are checking
Page_gizmochina.com/2019/06/10/relock-bootloader-oneplus-7-pro/
This is where you can read at the end:
"The above method only works if OnePlus 7 Pro is running on stock recovery and stock firmware. The ability to relock devices running custom recovery is expected in the next few weeks. "
That was published last month so, not sure if they got this to work on the OnePlus 7 pro yet.
So that's it, I am now using my new device which looks to work great and hopefully, won't get any bugs down the road.
I appreciate you taking the time to get back to me and will continue to learn about android.:good:
Hi all
I have just bought a new Oneplus 6 and wanted to install Lineage Os.
I had initially set up the OP6 with my google account and installed some minimum apps over a couple of days. The phone updated a couple of times. I think I started on Android 8, it definitely updated to Android 9 and I think it updated to Android 10. But I am not completely sure of this because I did not take notice at that stage because I didn't realise that this might have significance..
I followed the guide from the lineaoge os wiki here
wiki.lineageos.org/devices/enchilada[
I got as far as using adb to Fastboot boot twrp-3.3.1-2-enchilada.img (which was the latest image in the dl.twrp.me/enchilada/
It then got stuck in the qualcomm crashdump line on screen.
I spent a day checking posts, including here on XDA. There are a lot of posts dealing with this issue and I did try to follow some of them with less or more success but no resolve. I downloaded Android 9.02 and used the following instructions
techtrickz.com/how-to/recover-oneplus-6-and-6t-from-qualcomm-crashdump-mode/
The routine started to run and then posted a series of error messages and exited. ( I have a screenshot of the terminal window but cannot see a way to post it here)
I have tried to research this further and there are plenty of posts and lots of suggestions. But to be honest I have become confused as some of the posts give significantly different solutions to each other.
I wondered whether it would be possible to give me some help or point me in the right direction to a post which is current and has the steps that I am likely to need succeed..
Thanks in advance for any help you can give.

I would recommend using fastboot flashable stock rom from here. People also like to use msmtool, but I feel like it is an overkill.
Please note this warning:
These ROMs can't be used to update or downgrade your phone but just to restore your phone, so don't use them to come back to oreo or to update from oreo to pie.
So grab the latest oxygen os 10, and follow the instructions to flash it. After that, if you are feeling a bit paranoid maybe download a zip from oneplus and do a local update. You now should have your phone back.
Official TWRP does not support android 10 yet, as far as I understand, so that is probably the issue. If you want lineageos 16, you should downgrade to android 9 using a downgrade package provided by oneplus and then update to Oxygen OS 9.0.9.
There is unofficial twrp by mauronofrio that supports android 10. If you want to go from OOS 10 to some other android 10 rom

Thanks very much for your helpful reply. I am now back to a working phone with Oxygen os10. And you have also explained what was wrong when I tried to fix it, I was trying to load an Oxygen Os 9 on a phone that had already been upgraded to 10 and you have explained what went wrong in the first place, I was trying to flash an incompatible TWRP image onto Android 10. So your short post has explained a lot. Thank you.
I am not feeling paranoid unless you advise that I should be and I do want to install lineage os. So I need to revert to Oxygen Os9. I have looked on the Oneplus site and that have found the option to Upgrade to 10.3 but no option to downgrade. In the Oneplus community there is a link to downloadable ROMs, these are divided into a number of folders some of which look not applicable. There are three folders that look of interest
1. Signed flashable zips
2. OTA incremental update zips
3. Stock boot-recovery images
Here is the link /forums.oneplus.com/threads/oneplus-6-rom-ota-oxygen-os-mirrors-for-official-oxygen-os-roms-and-ota-updates.835607/
I can see it is not the OTA Incremental that I need but am unsure if it is signed flashable zips or Stock boot recovery images. or whether it is neither.
Do I flash as normal or would it be a local update?
I would be grateful for any further advice.
Thanks again and for any help provided now.

I have had luck with this downgrade package. I basically googled it, the package is hosted on a legitimate website, so that's what I used. Just download it, put it on your phone and do a local upgrade through updater app.
Once you have done that I would recommend upgrading to the latest Android 9, which is OOS version 9.0.9 I believe. Then go ahead and follow instructions to install lineageos.
I am actually on LineageOS 16 + MicroG right now, so I ran into the same problems you did Glad I could help!

Thanks so much for your reply again.
I used your downgrade link and that all worked well and then let it upgrade to OOS 9.0.9. Again all very positive.
I then tried to flash TWRP to the device using this image "twrp-3.3.1-2-enchilada.img" It appeared to flash okay. Then I issued the command
"fastboot boot twrp-3.3.1-2-enchilada.img" over my adb connection and it returned to the Qualcomm Crashdump error.
I presume I have to start again with the exception that this time I can use a flashable stock rom that is OOS 9.09? Is that correct?
Then do you have any suggestions for getting round the TWRP problem? Did you use a different version?
Thanks in advance for any help.

Hm. Yes, unfortunately the safest thing to do is to start again. But you can start with 9.0.9 right away.
People have been discussing a similar issue here. It seems like using unofficial twrp by blu_spark helps. Maybe twrp-3.2.3-x_blu_spark_v9.91_op6.img or maybe try the latest one.
Also, make sure you read the instructions on lineageos website. Make sure you have oem unlocked, usb debugging enabled and you clicked "always give access to this" device or something, do the fastboot set_active a. I have also used fastboot flash boot_a <recovery_filename>.img. However, I do recall using fastboot boot <recovery_filename>.img some other time and I think it worked....
Anyway, yeah, maybe try this modified recovery by blu spark and follow the instructions carefully.

Thanks very much for your helpful reply and apologies for the delay in my reply to this post, I have been tied up with work the last couple of days.
I did re-install OOS 9 and then followed the instructions on the Team Win site to install TWRP in the Oneplus6. I had success after I used the latest TWRP image and zip from that site . I was then able to install Lineage OS and Microg as I wished.
So thanks for the help all. Really appreciated.
