Flash OOs Oreo Stable release

Folks,
Seeing alot of comments about bootloops, etc after trying to install the new stable OOS Oreo release.
I went through the same issue myself and found the following method to work best.
PLEASE NOTE: I'm not responsible if this does Any type of damage or issues to your device.
Be sure to backup all you need to back up to your PC.
1. Complete wipe of phone.
2. Flash the stock recovery that was used for reverting from Oreo Beta to Nougat. http://oxygenos.oneplus.net.s3.amazonaws.com/OP5_recovery.img
3. Wipe everything again.
4. Sideload new Oreo release. (Credit @HatRiGt, https://drive.google.com/open?id=1NW5zyUOL6bWgUWozFGLiutzud203npKp)
5. Reboot to bootloader and flash the Chinese TWRP. https://drive.google.com/open?id=1AKbC4HB0h4rEldQUowWGdyM4iYBVV--7
6. Reboot to recovery and flash Magisk. I flashed the 14.6 version and haven't found any issues yet. (https://forum.xda-developers.com/attachment.php?attachmentid=4366826&d=1513897917)
7. Boot phone.
I cannot promise this will work for you, but it has done the job for me.
Running Oreo Stable with Magisk 14.6 and restored all apps from Titanium Backup that I saved on my PC.

I highly suggest blu_spark TWRP instead of chinese one, and i think this method is ONE of the other working way

Couldn't get mine to work with blu spark, hence why I had to use chinese

Link for Chinese twrp please

Thank you very much, work for me

Make a video of it please

New Magisk v.15.
Thanks to topjohnwu.

Added to OP.

All is well. And with google Drive almost all data is back.

Nice & easy workaround..
Step 5 has to be : install TWRP on fastboot mode...

@hallo dare
Any chance you can make a very detailed video about this process?

You should try changing the TWRP

If you have problems with adb sideload:
Boot into fastboot and install stock .
Unlock/Lock your Phone and unlock it again. Locking will wipe the whole phone.
After this you can make a clean installation.
Reboot to bootloader and flash the Chinese TWRP and boot to Recovery.
Install the oreo.zip file.
Reboot to System.
Make your Setup: WLAN, GMail Account aso.....
After all boot to Recovery and install Magisk

Very easy, put oreo zip file in the root folder, backup all data, flash stock recovery, boot with stock recovery, wipe cache, upgrade internal..., Select oreo zip file and flash it, then back and select wipe, select erase every thing and reboot. Done.

Thank you so much! I finally got it working. I needed to do a factory wipe and skip the magisk installation but it worked!
Cheers!

Magisk won't flash on stock recovery, if that's the reason you had to skip installing it.

No I installed the TWRP and flashed magisk. It refused to boot so I factory swiped it and all was good. Now I have to figure out how to install magisk without getting into bootloop.

I am not sure . I flashed the latest version till now there are no new update . I think candy Os is a treble ROM try non treble rom

Using the treble supported TWRP fixed the vendor mount problem but I get into a bootloop when I try to install Magisk (latest version). I'm using the Havoc ROM (Android 8.1.0 - Treble Supported).
Edit: Got Magisk running by using a modified version for Treble.

Hello I also installed the same ROM plus the Recovery of Red Wolf, remember that since its a treble you cannot mount vendor, but actually its easier than anything, why? cause the RR its based on Lineage OS and this last one is based on Cyanogen Mod, at the end what im trying to say its that the root services are already included in the ROM you only need to "unlock it" so i have the link for that, you only need to install this addon in .zip format (all the links and products are not mine, so please give thanks to the amazing developers). This is the official link and it also comes with an instructive step by step, I did the install trough sideload and now is working!
Example of command with adb sideload: C:\Users\kaks\Downloads\adb\adb sideload "C:\Users\kaks\Downloads\adb\addonsu-15.1-arm64-signed.zip"
www . cyanogenmods.org / root-lineageos-15-1-android-oreo-rom /
Hope this work for you as it did for me

Guide to install Android 8.1 or 9 custom ROM?

The question speaks for itself,I cannot find really any accurate ways to get started because I once tried to install Oreo beta (before official was out) and flashed a Oreo recovery onto Nougat and bricked my phone,and the only way was to use DC Phoenix so for now I have kept my phone on EMUI 8 stock.
So if anyone can tell me the steps to install let's say an Android 8.1 Treble ROM or Android 9 when it gets good as a daily driver,I know that you need to do the following things:
-unlock the bootloader
-install a recovery
-flash a ROM through fastboot or through recovery and after that flash Gapps and a modded version of Magisk
That is pretty self explanatory,but I have seen like that you cannot use TWRP since there is a problem when wiping data and that you need to have Huawei stock recovery and some important things to consider since I see it is pretty easy to brick these phones if you don't follow instructions but since there isn't really clear instructions to do some of these things,I am asking here if anyone can explain to me.
And yes,I do have my bootloader unlock code since as I stated,I tried to do this before.

And if I have downloaded a zipped ROM instead of an GSI,I do the same steps but in TWRP I flash the ROM with the Gapps and Magisk,right?
Also,can I use NoCheckRecovery for Oreo when I need to wipe data instead of stock recovery since I think it would come in handy if I would need to re-flash something through that without Huawei checks and it seems to be easier to find?
And I flash the recoveries to recovery_ramdisk,just to be sure,I know some things did change with Oreo so I am asking?

Pie gsi
Hi all,
I have installed Pixel Experience (Oreo) gsi ROM no problem. But if I try to flash any Pie gsi ROM it just goes into a boot loop. I flash system via fastboot and seems OK. Reboot and it just boot loops a few times and goes to the recovery screen that prompts to download and install the standard system.
Has anybody come across this or have any suggestions. I have tried a few different Pie gsi ROMs and same thing happens.
Thanks
Mick

[Guide] VoLTE guide for Oneplus 3/T (a workaround trick)

Hi,
Why VoLTE only works in Oxygen OS ? Why not in other custom OS ?
Many times I flashed my op3 for voLTE but no luck. I tried LineageOS, Mokee, etc etc but no luck.
At last I got it working and How ? please read below.
I know you must be thinking of whether this trick will work or not or is it fake .
Now you can really add VoLTE on your oneplus 3/T ()
Steps To Follow
1. At first install official Oxygen OS 9.0.6
(Remember it will replace your twrp recovery to official Oxygen recovery )
2. Reboot and see if you have VoLTE
Then,
Reboot to Fastboot mode your device.
3. Type "fastboot boot twrp_recovery.img "
4. now wipe all partitions except internal, recovery.
5. Install "Lineage OS / custom os "
6. Reboot.
and check by calling if your VoLTE working or not.
Thanks,
(Do report here if its working or not.)

Read correctly bro. First install OOS , it will install recovery too as well as firmware. and boot to TWRP via this command
"fastboot boot twrp.img" NOT "fastboot flash " ok.
After that format system,cache,dalvik in TWRP. and install your lineage os file.
And reboot system.
Done.
I am using Lineage OS 17 in OP3/t with working VOLTE in jio.
Try as it is all steps.

You can boot into TWRP without installing it. The trick is to open the command prompt (adb) in the folder where the TWRP image is stored in your PC. Or, move the TWRP image to your adb tools folder and open the command prompt there. Then proceed as the OP says.

You already on Lineage 17 is different than what I am talking about. Have you tried the method I Posted above in topic. No ?
Why I am telling to follow the same steps because VoLTE is all about a little tweak which happens in efs partitions I think. So when we install and first start the OOS it changes something in recovery level in efs/recovery.
When we install other os without formatting recovery and efs , VoLTE actually works. ( only if volte working in OOS then it will work in lineage via this method )
That's it.

I am trying understand your approach
Could you clarify ." wipe all partitions except internal, recovery" ? when i go to wipe, i can exclude 'interanl storage' but where is 'recovery' ?
If i am not wrong, you did dirty flash on 9.0.6 with LOS 17.1?
and i was on 9.0.6 and clean flashed LOS 17.1..

Didn't work for me..switched to Pixel Experience ROM where everything works.. pretty easy to flash PE if you are on LOS already

Didn't work for me though.
Clean flashed OOS 9.0.6
Volte enabled as per *#*#4636#*#*
fastboot oem unlock
fastboot boot twrp-3.4.0.img
Flash Lineageos nightly
Flash gapps
Flash 9.0.6 modem/firmware (just in case)
fastboot oem lock
No Volte on reboot :-(

Sorry for resurrecting this old thread, but i followed the steps and it didn't work. I too have airtel sim. On fresh install of OOS, I can see volte icon and volte working, but as soon as i booted into lineageos, it was gone :/ Anyone had any luck with airtel?

I am not responsible for any damage caused to your device by not following the steps or negligence at the time of this process, All the steps were carried out and tested on my personal device and are confirmed, My device Redmi 8 3/32, the version that i tested Havoc-OS-v4.5-20210208-Official-arm64-ab.img.xz
Bugs
videos recorded with the default camera do not play
Update: Install the NGCam_7.4.104-v1.8-fix.apk Once the application is installed open it take a photo close the application, this will create a folder in the SD called Gcam, inside the Gcam folder create a folder and call it Config7 and inside this place the XML file Redmi 8 GCam 7.4.104.314953318 G_Modder.xml restart the application and you're done
the only bugs that have is slow motion record not work for now
Automatic brightness does not work
Update: to fix the automatic brightness on your device, after installing the ROM, put in the folder SYSTEM-OVERLAY the treble-overlay-xiaomi-redmi 8.apk and set the permission for the apk on 644 ( use root explorer ) and reboot ..... problem solved
the necessary files are at the end of the tutorial
Steps
Note: I did the installation coming from Mui 12.EU, and there was no problem in the installation process or in the boot process
If you come from Miui12 .EU or any other GSI Rom go to step 4, if you come from the Rom stock follow the this steps
1- First make a backup of all the necessary information in case something goes wrong you can easily recover, Charge the battery at least 80%
All your data will be deleted during the process
2- Unlock the Bootloader if you have not already done it or do not know how to, follow this post: http://en.miui.com/unlock/

4- Make wipe only to Cache, Dalvik, System, Data and Internal SD
5- Format data,( if it doesn't format the data you will have bootloop) then Reboot into Recovery
6- Copy all the files to the phone (Havoc-OS-v4.X-20200522-Official-arm64-ab.img you can find it by unpacking the zip), Magisk,Magisk Path Fix, Permisiver, Certification Patch.zip, opengapp (recommended nano or pico)
7- Install system image to system partition (on TWRP go to install-Install image-System) .
8- Flash Permisiver v5 (on TWRP go to install selec permisver_v5.zip)
9- Resize system partition to flash opengapps (on TWRP go to Wipe-Advanced Wipe-Select System on the list-Repair or Change File System-Resize)
To Root
once you have installed an resized the system
10- Flash the Magisk path fix (on TWRP go to install selec MagiskA11_PATH_fix.zip)
11- Flash Magisk (on TWRP go to install selec Magisk-v23.0.zip)
12- Flash Opengapps
1-Flash Certification Patch
1 - Make a wipe to Cache and Dalvik

Hey !
I have a stupid question. Do you upload the GSI ROM and the other files on a SD card or on the internal storage ? I was searching this guide on the morning but I was wondering about that...
Thanks for your answer

You can place it in either of the two, as long as you can access the storage where you placed them from the recovery

Hi, I need to know some things to help you, what ROM did you have before flashing Havoc? do you have the bootloader unlocked? When did you use My flashtool, what method did you use?

In my particular case it was not necessary to flash vbmmeta as I comment in the OP I come from Miui12.eu, but it is necessary to avoid problems whatever the ROM you have before installing Havoc is to have the latest version of TWRP and have configured a lock pattern security in ROM access and in the flashing process I didn´t have problems

Hey!
I was on the stock ROM when i started to flash HavocOs.
I unbricked my phone with the MIUnlockTool V2 and my phone's still alive.
I booted on TWRP with fastboot boot TWRP.img 'cuz I can't boot to TWRP with volume up and power...
How can I flash HavocOs in the good way ?
I have Redmi 8 3/32 like you...

Ok the first thing is that you have the bootloader unlocked, if it is that way regardless of the stock version of the rom you have when installing twrp you must install magisk to ensure that the Recovery remains fixed in this link is a tutorial on how to install it, that tutorial was made by me and approved by Xiaomi https://c.mi.com/thread-2850424-1-0.html ,
install the latest version of TWRP and as it says in the tutorial then flash magisk, once you have everything ready install miui 12.eu do not do many settings except create a blocking pattern when starting the rom this is used by TWRP to be able to decrypt the internal memory
All ready do the steps as indicated in this tutorial (If you come from Miui12 .EU or any other GSI Rom go to step 4)
If for some reason you have a problem, use MI flashtool to return to the stock rom, but make sure to use the snapdragon method, select MIflash and when opening the screen at the bottom select clean all, this will prevent you from blocking the bootloader and you can start again without problems (note when selecting clean all at the end it will give you an error for not being able to block the bootloader and the device will restart, do not worry it will restart normally without problems)

Hey!
I thought about something this afternoon : if I flash HavocOS with adb and fastboot, we also haven't any problems with TWRP installation ! But the problem is that I haven't found any wiki to do that and i won't transform my phone to a beta tester....
Thanks a lot for your help but I think i will wait until a custom rom of LineageOs or HavocOs...

Hi . I am currently running havoc is 3.12 on my device I tried multiple times to flash this ROM without any success. Is not installing open gapps a problem ? Anyways when I flash this rom without flashing the certification patch I get a no os installed warning before rebooting from orange fox recovery but when I flash the certification I no longer get this message. Etherway I am getting stuck on a bootloop . How can I solve this issue? I did all the steps correctly wiping the correct partitions and formating data . Edit I wiped cache and dalvik after the bootloop without any success .

Hey !
I had the same bug before installing the v3.12 version.
I think it goes from the Permissiver v5. I think we should flash it to have the Havoc v4.
I'll test later if I have the time to do this and I'll inform you about the possibilities.
Hope I can help.

Thanks for replying and trying to help but last night I managed to get havoc 4.1 is installed by flashing lineage first (using another guide from this category). I will try again to get havoc 4.1 working without flashing lineage as soon as posible because I am curious .

Finally managed to flash Magisk on Havoc 4.1 with the help of youtuberking (telegram and YouTube).
How: just flash Magisk path fix before magisk and it's good to go.
