Downgrade from 10 to 9 - OnePlus 6T Questions & Answers

Will the Msm tool work? I only ask because sometimes if you try to install older bootloader it will brick your phone

MSMTool will work yes, but it does wipe the device completely and relock the bootloader.
You might wanna try using rollback package first: (https://oxygenos.oneplus.net/Fulldowngrade_wipe_18801_181024_2027_user_MP2_release.zip)
If you used magisk I'd suggest deleting all modules and rebooting first, then you perform a local update from system settings with this package.
It will install OOS 9.0.5 or 9.0.4 (don't remember now), and from that place you can install 9.0.17 with full zip package that are available on the forums.

Going back to 9 is a dead end, as security support will end (or already is).
At each major version of Android some people want to hold back. Interesting.

Lol, I don't want to hold back, but until 10 ROM support is truly stable, as in flashing, I'm staying on 9

I just reverted today without the MSM tool. Flashed via twrp but obviously had to wipe clean.

Have you tried this? I'm just sceptical about this since I read that even this will wipe data

Yes, this is how I reverted back to 9. And yes, it does wipe the device (along with sdcard, so back up that as well).
The difference is that it does not relock the bootloader. But to be honest, MSMDowload is better in the means that it restores the phone from scratch. I used the rollback package, and my phone claims that the system partition has 0 bytes left. After deleting apps from system folder they somehow reappear, as if it was still Android 10 without R/W permission. If I were you, if you decided that you can bear the necessary wipe of the phone, I'd go with MSMDowload.

Downgrading firmware from Nougat to Marshmallow

Hi,
I have a Nexus 6P that has Android 7.1.2 (N2G47W) installed. I've just unlocked the bootloader, installed TWRP then installed Magisk 16.0 for root.
I'd like to next downgrade from Nougat to Marshmallow. Are there any steps to do so? Can I just boot to TWRP, and immediately install the factory image from https://developers.google.com/android/images#angler?
Or are there any additional steps I need to take?
@goister You can't with TWRP download marshmallow from Google API site. Maybe do a good wipe in TWRP before hand of course back up anything important on comouter. Then follow the hiesenberg guide for returning to stock. Your in luck cause I've read with being on the latest Oreo can no longer return to marshmallow or nougat though I haven't verified myself. Best of luck mate.

Hi,
Not sure I get your post. My Nexus 6P is stock except for an unlocked bootloader, TWRP and Magisk root. Are you saying follow the guide at https://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928 specifically step 10. How To Flash The Factory Images (And Return To Stock)?

That's exactly what I'm saying unless you want to flash a marshmallow ROM. Then you can use TWRP but would still need 6.0 gapps and a computer to fastboot flash MM bootloader of that months build. MM vendor could be flashed by either fastboot or TWRP. Your best to download a MM build from Google site. Then unzip that folder and inside unzip again. You will get all the bootloader, vendor (radio optional) you will need for that months MM build. Then follow the guide from hiesenberg for returning to stock . Best to put all the images files and fastboot in the folder that is suggested in the guide . That way you can copy and paste the commands as written on the guide. There might be a flash all bat file you can use in the stock folder but not sure if MM had that I never used. If you have any more questions feel free to ask.
Yes I intend to flash the stock Marshmallow ROM from https://developers.google.com/android/images#angler specifically the latest one (MTC20L). My end goal is a rooted Nexus 6P with the MTC20L firmware. Wouldn't the stock Google build already have gapps? I don't intend to use a 3rd party ROM.

Yes that's right gapps not needed with stock. Wasn't sure on your level of experience so mentioned that with a ROM you would need gapps of that android version . If I where you I would back up my phone completey and wipe everything in TWRP including internal before hand. So many times files get left behind especially using different versions of android to avoid any issues. Be warned though wiping internal includes pictures, downloads, music, documents etc.

Thanks. I've no issues wiping the phone as this is pretty much a fresh phone. There's nothing to even back up. The only thing I've done so far beyond rooting, was to import a certificate into /system. I suppose a factory reset would delete this certificate and bring it back to stock (but rooted)? Or should I wipe with TWRP instead?
Looking at the zip file of the stock ROM, here's what I see
bootloader-angler-angler-03.54.img
flash-all.bat
flash-all.sh
flash-base.sh
image-angler-mtc20l
radio-angler-angler-03.61.img
After wiping with TWRP, would I be able to run flash-all?
Edit: I've just TWRP wiped everything, and rebooted. However, the device is stuck at the initial "Google" screen with the lock icon at the button. How long is it supposed to take to boot up after a full TWRP wipe?
OK I solved the problem. Apparently if you reboot after the flash, you need to disconnect the USB cable, else it will boot loop.

Oneplus5 - OTA Update from 4.1.15 to 5.0.1/5.1.4/5.1.5 not working

Hello Community,
I am trying to update my Oneplus 5 (A5000) from
OxygenOS 4.5.14 / Android 7.1.1 / A5000_23_171031
to
OxygenOS 5.0.1 (OnePlus5Oxygen_23_OTA_028_all_1801031502_04d7cc5.zip)
OxygenOS 5.1.4 (via OTA)
OxygenOS 5.1.5 (OnePlus5Oxygen_23_OTA_038_all_1808082017_028e075c45a84106.zip)
I am getting an "Installation failed" error, no matter which option or image I use to upgrade:
- Download from Oneplus Homepage and Install local file from recovery
- Updating via "System updates" in Android
- Updating via "System updates -> local upgrade"
I read all the posts in this forum from the last 2 months, but nothing really seams to work:
- wipe the cache in recovery
- install "older" version than 5.1.4/5.1.5 - in my case 5.0.1
- try different methods like flash from recovery, flash from local upgrade in Android...
I have an unlocked bootloader, but the phone is not rooted. I can not tell exactly if TWRP has ever been used before, because I bought this as a used phone, which already had an unlocked bootloader. Nevertheless I was able to install previous OTA updates. But now all updates are failing.
Anyone here who could help me please?
Best Regards,
Daniel

Hello, Do you have twrp running or stock recovery? Have you ever tried to factory reset and then install 5.0.1/5.1.4? Or format internal storage too and afterwards install the full 5.0.1 or 5.1.4 oos rom?

Thanks for your response. I use stock recovery. I didn't try to do factory reset or format internal storage, because I don't want to lose any data if possible.

Have you at least wiped cache in recovery(you did not mention which sort of recovery you have). Wiping cache is also an option and you'll not loose any data.
Recommendation: keep in mind to backup your whole phone from time to time
There was a similar post to this one recently where a device wouldn't update to any version of OOS. Relocking the Bootloader first was the solution in that case. You could try that.

Thanks for the reminder, I agree a 100% with you. :good:
Phone is fully backed up, I still prefer not to lose any data, as setting up everything again is not the most enjoyable thing for me.
Wiping cache via stock recovery is something I already did before, unfortunately luck.

Thanks! I think I already have seen this post, but can't find it right now. You are right, the solution was to lock the bootloader.
I wanted to avoid deleting all my data. Therefore I am primary looking for another solution. Maybe instead of going back and locking the bootloader again, going into the "other direction" where I can take advantage of the already unlocked bootloader, e.g. install custom recovery and update OSS this way? What do you think?
Best Regards,
Daniel
I had the same issue some weeks ago and the solution for me was to update from 4.5.14 to 5.0.0 with all data reset (i had already lost everything anyway). But you can maybe try it without wiping everything, only Dalvik cache. I can't find where I downloaded the 5.0.0 version (that is not stable) but I can maybe upload it on mediafire for you if you want.

Thanks for sharing the knowledge. Did you also have an unlocked bootloader?
I would really appreciate it, if you could upload the 5.0.0 image for me. Then I would give it a try. :good:
Yep unlock bootloader and unable to relock it, for unknown reasons (I didn't try again since).
I'll upload the 5.0.0 OOS when i'm back home tonight .
Think about using blu_shark modified TWRP, it's full Oreo compatible.

here there is the 5.0.0 OOS versions I've found : http://www.mediafire.com/folder/97sy3q5jde1tj/Roms_OP5
But be careful, and download the 5.0.1 also because the 5.0.0 is really unstable (5.0.1 is a hot fix). I used 5.0.0 only to go to 5.0.1 right after minimal configuration.

Thanks for your effort. I haven't had the time to continue with my open task.
Unfortunately, I came across multiple postings which explicitly warned of lost data, bootloops and other strange behaviors when updating from 4.5.14 to 5.x.x while having an "open/unlocked" bootloader.
I am a little bit worried this could also affect me in my situation. I am really not in the mood to brick my device...
Maybe I will reset everything, lock my bootloader and install everything from scratch. Just need to find the time to do this.
Even after a factory reset I wasn't able to go from 4.5.14 to 5.x.x, maybe it's link to the fact that I wasn't able to relock my bootloader. Anyway give us some news, could be useful for the next guy with the same issue !

Lineage OS 16 in Oneplus 5 - July 2019

Hi,
I bought a oneplus 5 phone because I was told it was going to be easy to install Lineage OS. I have try to install Lineage OS 16 on it for 2 days without success.
The first issue i had was installing twrp. Most of the twrp available did not worked with my phone. After flashing them with fastboot and reboot to recovery I would end up with a black screen and the the blue led turn on.
However I did find two TWPRs that work:
- twrp-3.2.1-1-cheeseburger.img
- twrp-3.2.3-0-20180822-codeworkx-cheeseburger.img
There might be other that would work, but this are the ones that I have tested.
After being able to boot to TWRP I try to flash the firmware 9.06 with success. Without reboot I flash lineage without success. I try to reboot and the system did not worked and I never reboot.
After a while I found a OxygenOS 4.5.10 that I hope is the stock rom. I has the following sha256sum: 7a8268f6a133f090a2d304aad2f92393aefbd4df34a6c2ed088909aaf7ccc2dd
That did worked and give me a breath. At least I had a working phone now. However I try to update and it did not worked.
From there I have been strugling with this project to install Lineage OS in my new phone. I know there are guides out there, but most of them did not work or are outated. There ara also threads in this forums, but are to big to try to follow. So I start this one, hopefully you can help me.
It would be great if there is a step by step guide on how to run Lineage OS in this phone.
Best,

Hello, seems that you did not follow the installation instructions within the official LineageOS thread https://forum.xda-developers.com/oneplus-5/development/rom-lineageos-16-0-pie-oneplus-5-t3843064
Your issues are clearly missed or skipped steps.
Please follow the instructions there and if you get stuck, report back with detailed information :good:
Thanks a lot for your quick response. It do have an issue with that guide and it is with point 1:crying::crying:

I have OxygenOS 4.5.10 and it does not upgrade to OxygenOS 5.1.4. What happened, is that in my first attempts to get this thing working I brick the phone and loose the stock firmware. Then I found this rom that allow me to use the phone (OxygenOS 5.1.4)
OnePlus5Oxygen_23_OTA_015_all_1708252353_f05918.zip
sha256: 7a8268f6a133f090a2d304aad2f92393aefbd4df34a6c2ed088909aaf7ccc2dd
It make the phone usable, but not upgradable. I doubt is the original, but I found the link on the Oneplus forums. (I can not post links because I am too new here)
After that I search for a ROM that comes with 5.1.4 and was really happy, and try to flash. It did not work, it is like it tries to boot, but never finish booting. I wait at least for 10 minutes. This the file and the sha256 hash:
OnePlus5Oxygen_23_OTA_037_all_1807181258_7b4b6.zip
sha256 2bb2e21a43572ac4bd2e5d1d30a3fb7562ddec280df3d452d61f58a4a8135f14
So I guess my first step would to find a way to get Oneplus 5.1.4 working. When I first try to upgrade the phone, I upgrade it from OxygenOS and it worked, however then I mess things and brick the phone. I found the rom that allow the phone to work (4.5.10), but for some reason the upgrades do not.
Thank you very much for your time.

You need to clean flash oxygenOS 5.1.4, then take ota update to 9.0.7 so you have the latest firmware.
Clean flash means that you need to wipe system, data, cache and format internal storage too.
So please backup everything off your device at first!
Everything you need you find here on xda, like the roms https://forum.xda-developers.com/oneplus-5/how-to/oneplus-5-mirrors-official-oxygen-os-t3628190

Finally I had time to work on this. The rom for 5.1.4 is: OnePlus5Oxygen_23_OTA_037_all_1807181258_7b4b6.zip, that I already tried and never boots . With twrp it seems that the Rom is installed, with the stock recovery the installation never ends. I am going to try with other ROMS. Hopefully one of them would allow updates.
I am going to start with the newest 5.1.7, and if that does not work would keep going down.
Thanks again.

5.1.7 did not boot, however I have some progress. I installed 4.5.12, I was previously at 4.5.10, so my android setup security patch levels went from July 2017 to to September 2017. Small step forward.
I have have that hypothesis that it would work with 4.x.x versions and not with 5.x.x versions. Tomorrow I would try to flash the latest 4.x.x and the earliest 5.x.x to see when does this things stop working.
I did the tests and I can flash up to 4.5.15. I tried to flash 5.0 and that did not worked. It flashes correctly, but it never finish booting, I waited up to 10 minutes.
So there is something preventing the phone to use version 5.x.x Should I try upgrading the firmware? Other ideas?

Please give detailed steps what you did including file versions. Otherwise I cannot help further.
Every oxygenOS version has firmware built in, no need to update it seperately.
Follow this:
1 flash this recovery with fastboot like the first time https://drive.google.com/file/d/1UlTftbe6wooAs4Fp0cjwXlOKmfQHgdfL/view?usp=drivesdk

I keep loosing root after reboot, Pls help.

Hey guys,
first time posting here so i dont kow how to style the text, so sorry about that.
last time i rooted a phone was on my sony xperia sp , where all i had to do was to go to towelroot .com and click to root.
I tryed to root my OP6T yesterday, after some setbacks i managed to sucessfully do it.
I did it like this:
1. Downloaded full ROM of OOS 10.3.2,
2. copied the payload to a program called payload dumper that extracted the boot image.
3. Copied the boot image to the phone
4. opened Magisk manager and selected install from source where i chose the boot.img
5. it created a copy called magisk_patched.img
6. booted in fastboot
7. on my pc used the command prompt to "fastboot boot magisk_patched.img"
booted normally and i had root.
but then problem appeared
#Problem 1
everytime i rebooted my phone i would loose root and it would say Magisk not installed. To get it back i would need to perform step 7 again and it was not ideal to do that everytime i turned off my phone.
#Problem 2
While tryng to solve problem 1 i read that i needed to open magisk manager and "Install to Inactive Slot (After OTA)."
After doing that it rebooted but now it wont boot at all, even if i try to "fastboot boot magisk_patched.img" the cmd gives me error:
fastboot boot magisk_patched.img
downloading 'boot.img'...
OKAY [ 0.838s]
booting...
FAILED (remote: unknown command)
finished. total time: 0.845s
now my phone is just sitting there i dont want to reset it again. it would be the 4th time that i need to set up my phone in 2 days, so im trying to see if there are alternatives.
If reset is really the only way, i read that with root you can make a full backup of your phone and then restore it. How to do that? can i do it in the situation im in?
How can i root my OP6T running OOS10.3.2, and keep it? Whats the right method bc the one i followed seemed flawed.
I also tried one that had TWRP but maybe i did something wrong bc it didnt work., also there is no official one working for 10.3.2.
What is happening is normal with those instructions (they aren't right).
All you need to do is install TWRP. Do not use the official one, it is out of date. Use TWRP from this thread Link here. The TWRP from that thread is from the official maintainer. It works fine with OOS 10.
- You need to get the phone in fully working order again. Which may mean you need to use the fastboot ROM, as you've probably "goofed" something up at this point. (no offense meant). Make sure your phone boots and such after this.
- For OOS 10 with the phone in fastboot, fastboot boot recoveryimgfilename.img (<-- For OOS 10 you will need TWRP 3.3.1-32 Q Unofficial by mauronofrio from the thread I linked to above) This will boot to TWRP.
- Now run TWRP 3.3.1-32 Unofficial Installer by mauronofrio this will install TWRP. The installer is the same for Android 9 and 10, doesn't matter.
- Once the installer runs, click back, choose reboot to recovery. If you boot to the system, you have to start over. Reboot to recovery!
- Install Magisk 20.3 <-- The current version. The official download page. After that you can reboot to the system. You should now have a rooted, phone with Magisk, and TWRP installed.
Any questions ask.

So getting it straight, i need to first reset my phone and then do the steps you described.
Can i backup the data first with TWRP to restore it later and avoid setting up everything again?

Supposedly. I've never used that function of TWRP. Some people have luck with, some people restore things that shouldn't be restored and end up having to wipe the phone again. Personally I just use TitaniumBackup like I always have. I would search for information on that in the TWRP thread if you want to try method. I don't know enough on that to provide solid information.

Hey man,
Thank you so much. It worked and i stay rooted even after reboot.
May i ask how you use the Titanium Backup, i think back in the days all i used it for was uninstalling system apps. Or if you know some nice guides. If you know other good things to checkout now that i have root i would appreciate it, i have been far away from rooting for too long.
Once again thank you so much

I use it to back up app and app data primarily. It allows me to restore data to apps after a clean install. Since I have the Pro version it's just a batch action (one click essentially). There is also a way to create a flashable .zip you can use in TWRP, although I haven't tried that method, as I'm typically not restoring apps, just data. I also use it remove apps from time to time.

Hey man, im sorry i am once again in need.
Idk why but at first i can reboot the system normally without issues. but after a while once i set up everything it just doesnt boot anymore. Am i missing something? do i have to do anything with magisk? download a module or something?
Could it be that google security update is the fault?

When you installed everything originally did you fix everything with a clean install? Both slots are the same version of Android? (Like you don't have something weird going on like Android 9 on one and Android 10 on another?)
You definitely have something abnormal going on. There shouldn't be anything in Magisk that you have to do, at least not to prevent crashing. I normally hide it, but that has to do with keeping apps from detecting root.

I got it to boot by uninstalling magisk,
I am 100% sure i dont have two different version of android in different slots, bc yesterday i was in big trouble and nothing was working and i flashed on both slots the same version of android 10(dont remember exactly wich one as i tried a couple, but they were the same).
Today when i couldnt boot anymore i went into stock recovery, factory reset -> when it booted i placed the stockOS.zip file in the phone and applied update from local file -> after that i factory reset again from the system settings, so i think the phone should have installed it properly.
Only after that i did what you told me and installed TWRP and Magisk. and as i said it worked and i could restart my device etc..
After a while when i restarted i couldnt boot anymore and went to bootloader. Removing Magisk fixed it,apperantly on install magisk creates a copy of the boot.img that it restores on uninstall, and i booted to system.
Now i can use my phone but dont have root.
Im very thankful for you being there and helping me out trough this, i cant thank you enough

Not sure if you're still having this issue but I'll post the solution just in case anyone gets stumped, does a google search, and comes across this post. You were using the wrong command.
"fastboot boot" just lets you boot with the img so you can verify that root works.
"fastboot FLASH boot" will flash it and root will stick after reboot.
No need to jump through hoops with TWRP and such.

recovery the bricked phone, but how can I upgrade to android 9?

just use MsmDownloadTool V4.0.exe to recovery my op5 to oos, but the version is quite low as Android 7.1.1.
checked the system update, it told me up to date. which is of course not true.
tried to clean the cache of google framework service and oneplus framework service, still nothing in updating.
tried installed oxygen updater, and download 3 update zip from 7.1.4, 8, last version of 8, but each time I use local install in system uploading, then reboot to recovery, it shows me "failed". none of version works.
I even tried to install in recovery, wipe cache and data or just wipe data, then install from internal disk, none of the file works, even don't have any popup fail notice, just go back to file chooser interface.
I can still go back to system by switch off and on again.
How can I upgrade the old version of android in my oneplus 5?
original:
used use lineages os with Twrp, and I would like to flash to original oxygen.
download full rom zip in https://www.oneplus.com/uk/support/softwareupgrade/details?code=PM1574156143164
copied to phone disk
went to twrp
wipe Dalvik, System, Data, and Cache
then tried to install the full rom zip, but met "no Digest File found" error
found it must be twrp old, so I download new one in https://dl.twrp.me/cheeseburger_dumpling/twrp-3.4.0-0-cheeseburger_dumpling.img.html
copy to phone and flash it to recovery.
select "reboot to recovery"
then problem coming: I can only see the oneplus logo with powered by Android. it won't go any further.
I am not sure any thing wrong during my processing, but maybe 2 things:
1, I wiped the system
2, I didn't clean the screen lock pin before I flash
so, my question here is, if possible I can flash the original oxygen os in this situation?
if positive, could you please give me a step by step instruction?
by the way, the zip rom I download from oneplus site isn't have the "flash-all" script.
please please help me .

thanks! it works! i'm at 5.1.2 then i install OxygenOS 5.14 (OnePlus5Oxygen_23_OTA_037_all_1807181258_7b4b6.zip) then after that I install OnePlus5Oxygen_23_OTA_042_all_1812232102_a034988b.zip and then the last and the latest OnePlus5Oxygen_23_OTA_068_all_2006012224_c7a6016.zip android 10.
Please help. I bought a phone with Beta installed. I wanted to switch to the original system. So I screwed up something so using the MsmDownloadTool tool I wanted to use it by uploading everything from scratch. I fell into the Chinese H2Os system. I searched again and I already have the original ColorOS based on Android 9. But I can't update it to 10. What do I have to do? Oh .... the bootloader is unlocked ...

thanks for replying
I had figure out my problem.
it seems the rom I flashed using MsmDownloadTool had something wrong,
I've changed another one, it shows me the update from the first start after flashing.

if you are directly flash to coloros android 9 from lower version other than android 8, it might be the problem you won't got the update in the system. It might be have issue in wifi or gps as well, which I bet you didn't well test yet.
that's all about the system partitions messed up. regarding my understanding.
solution is simple, but time consuming:
you have to flash an original rom using msmdownloadtool, make sure that rom will have update notification in the system menu of settings. then upgrade from there one level up each time, till to the android 10. (chinese version do have 10 available)
than, you can download oxygen os android 10 to flash on the coloros android 10 (hydrogen os android 10) you just done the upgrade, don't forget wipe data/cache before flashing.
hope that's helps.
