I wanted to share the steps I took to get OOS 9.0.6 successfully booting, coming from a custom ROM + TWRP.

For some reason I had a lot of trouble getting this working on my phone. I kept getting stuck on the circle boot animation

0. Download the zip from post #2 (I had tried with the official full OTA zips from OnePlus' website, which had slightly different file names. I wonder if this makes any difference)

1. Upgrade to TWRP 3.1.1

2. Wipe > Advanced Wipe, select Dalvik, Cache, Data, System

3. Return to Wipe, select Data, press Repair or Change File System. Press Change File System, and select F2FS. (this step was important for me, I was previously on EXT4)

4. Reboot into recovery

5. Plug the phone into your PC and copy over the OTA zip

6. Install > Select the OTA ZIp

7. Reboot. It took me about 5 minutes to get to the setup screen.

Hope this helps others in the same boat.
[OnePlus 3T Guides, News, & Discussion] BillGoss:
You made things difficult. OOS works fine with an ext4 data partition.

But OOS also encrypts the data partition.

So, if you had an unencrypted data partition, the first boot of OOS takes a long time as as it encrypts the data.

All you needed to do was wipe data and flash the full zip. Then *wait* for the first boot to complete.
[OnePlus 3T Guides, News, & Discussion] BillGoss:
There's absolutely no reason to wipe system. The installation zip completely overwrites /system (it flashes system.new.dat).

There's also no runtime components in /cache and it's not used by apps or the OS so there's no reason to wipe it either. Have a look at what's in /cache. Note that Magisk uses /cache as temporary work space when it's installed, so one can ignore all the fstab files and other stuff.

In the good old Dalvik days you had to wipe it to get refreshed runtimes built. Since the switch to ART this is no longer necessary as the OS does this dynamically at startup (checks and rebuilds any changed apps).

None of the last six OOS updates have required wiping data. So, unless one is coming from a non OOS ROM, there's no need to wipe data.

Note: the reason for wiping data is that the data structures of system components is different between ROMs. The only effective way to clean out the old system data is to wipe /data.

User app data doesn't change between ROMs or system updates.

So, bottom line: if you're coming from stable OOS, then nothing needs to be wiped!
[OnePlus 3T Guides, News, & Discussion] cryptonit:
Thanks!

That's what I thought.

Might be good to update post 1 as I'm sure people will blindly wipe more than they should.

Thanks again.
[OnePlus 3T Guides, News, & Discussion] catalindinsibiu:
You are right, I wiped data and found out my apps are missing (obviously ?). Fortunately the time spent for creating the backup before install was not wasted.
[OnePlus 3T Guides, News, & Discussion] Vuska:
is it different with 5.0.1 before this?

any news about difference?

anyone has already flash it ?

if much different, especially battery... i will download it..

sorry.. i have very limited data plan..
[OnePlus 3T Guides, News, & Discussion] matmike:
It seems to be exactly the same. OP provides a MD5 hash values and I just checked the file I did get via OTA (full ROM as I'm rooted).

Both have the exactly same MD5 hash and therefore are identical.

The OTA file is called "OnePlus3TOxygen_28_OTA_062_all_1712272248_fc84.zip" in my case.

BR,

Matthias

Something went goofy, I followed the steps to flash and now I am stuck at a weird screen.

Downloaded and flashed blu spark TWRP

Booted to recovery, flashed full zip file for 5.0.1

Did not flash SuperSU or Magik to root

Restarted phone, had the boot page for 4-5 minutes (red dot circled by two white dots)

Phone rebooted again, now is at a 1+ screen asking language, so I choose English

I am given options to install from internal storage, Install from ADB, Wipe Data & Cache, Advanced, and exit

Any ideas????
[OnePlus 3T Guides, News, & Discussion] Pablo.x:
You're on stock recovery. You have lost TWRP due to flashing official OxygenOS without flashing any root method.
[OnePlus 3T Guides, News, & Discussion] DarkSJ1998:
Ohh... Is it so? But I remember that once I clean flashed OOS without Magisk or SuperSU, my BL was Unlocked & my device was Certified. :/
[OnePlus 3T Guides, News, & Discussion] RASTAVIPER:
You shouldn't have any issues booting at the system.

Unleashed by my rooted OP3T in 8.0
[OnePlus 3T Guides, News, & Discussion] Didgeridoohan:
Do you mean "Device certification" in the Play store? That can take a while to update... A SafetyNet check will fail if your bootloader is unlocked.

3T got encrypted again after 5.0 upgrade

Greetings all .. Last week I upgraded my 3T to OOS 5.0 using twrp-3.2.1-x_blu_spark_v8.61-op3_op3t and Magisk 14.6. After flashing it took more than 20 minutes see any progress and I found that complete internal storage has been wiped clean and again device is encrypted (previously it was unencryted), lost all my data and I believe even if I had taken nano backup it'll be gone too.

I uploaded OOS 5.0.1 full zip and plan to flash again to latest version. When I boot to recovery I get the prompt to unlock screen using pattern I set for bootup and screen lock on phone, my questions are:

1. Do I remove the pattern lock first?

2. If I flash with 50.1 full zip, will I face the same complete device wipe?

3. Do I need to unencrypt the phone first?

4. If I lose all data including OOS5.0.1 zip, how can I upload zip to phone using bootloader or TWRP?

5. Can I lock bootloader and still have root?

Thanks in advance and hope you can help, please.

Is it required to decrypt the phone to Flash OOS 5.0.1 with Magisk 14.6? Running twrp-3.2.1-x_blu_spark_v8.61-op3_op3t ? Currently running OOS 5.0
[OnePlus 3T Guides, News, & Discussion] Siddk007:
its upto you whether you want your phone to be encrypted/decrypted. you can upgrade to 5.0.1 with encryption.
[OnePlus 3T Guides, News, & Discussion] jesrani:
Just dirty flashed as per instructions. Since 30 minutes just seeing 2 white balls going around a red ball. Hope it will move further. Did it take so much time for others also?
[OnePlus 3T Guides, News, & Discussion] Siddk007:
1. Yes, always remove any lockscreen pattern/password to avoid any issues in TWRP especially if your phone is encrypted.

2. I dont know what are your steps to install the rom but if you just wipe dalvik and cache (if upgrading from OOS 5.0 to 5.0.1), your storage should be fine.

3. Its upto you, whether you want your phone to remain encrypted/decrypted. Not at all a compulsion.

4. While in TWRP, connect your phone to pc/laptop using usb cable and internal storage will be visible. Copy necessary files you want to your phone.

5. I'm not sure about this, so cant answer. I will better leave it unlocked to enjoy custom roms and other stuffs :p
[OnePlus 3T Guides, News, & Discussion] jesrani:
Made the mistake of rebooting the phone as it was not starting. Now it asks for password in TWRP. When I rebooted, it gave message "Encryption unsuccessful". No storage visible in TWRP. What to do?

Edit : Had to wipe data and reflash. But had backup.
[OnePlus 3T Guides, News, & Discussion] junostik:
Great work and Thanks Sid.. flashed and upgraded to OOS 5.0.1 without any issues. I used Magisk 14.6 during flashing and installed Magisk Manager 5.5.5, is it safe to upgrade Magisk to 15.3 for OOS 5.0.1?

Any debloater zip file for OOS 5.01 that was tested and working ?

Can anyone post, running rooted oos 9.0.6 with stock kernel and stock thermal engine, this file?

/vendor/etc/thermal-engine.conf

I need to test if its my phone, which is getting warm and thermal throttling during dash charging, is due to the pixel based thermal engine in los based roms or something specific about my phone..
[OnePlus 3T Guides, News, & Discussion] saspo59:
I run oos 9.06 with magisk all rest is stock no problem with dash charging nothing inside the file u mention see pic
[OnePlus 3T Guides, News, & Discussion] :
No from a running oos but from unpacked 9.0.6.

EDIT:

Before you ask: it's the original shipped file - I'm not kidding.
[OnePlus 3T Guides, News, & Discussion] AKHIL.cochin:
in 9.0.5 with latest TWRP and latest Magisk , do i have to perform full wipe or just dirty flash the entire zip ?

Thanks in advance .
[OnePlus 3T Guides, News, & Discussion] BillGoss:
Dirty flash is fine, though you'll have to also flash Magisk (OOS doesn't support addon.d).
[OnePlus 3T Guides, News, & Discussion] AKHIL.cochin:
Encrypted also , will i lose data ?
[OnePlus 3T Guides, News, & Discussion] BillGoss:
No, you'll be fine. It's only coming from OOS 5.x that's a problem.

please support

[MENTION=3840410]PetrSP7[/MENTION]
[OnePlus 3T Guides, News, & Discussion] DarkSJ1998:
Just boot into the recovery and do a Wipe Data/Factory Reset. You can download the 9.0.6 zip file and install it via Stock recovery.
[OnePlus 3T Guides, News, & Discussion] rohan164:
Hello [MENTION=5457804]DarkSJ1998[/MENTION],

thanks for your reply.

but when i Wipe Data/Factory Reset, i will be on 9.0.6? or on downgraded version?
[OnePlus 3T Guides, News, & Discussion] DarkSJ1998:
Wipe Data/Factory Reset just affects the /data partition, ie, it doesn't at all affect the /system Partition/ROM. So you'll stay on the same SW version, 9.0.6 in this case.

Beta

I'm currently on Open Beta 30 (last beta rom). Should I just download this and update? Or is there other things to do?
[OnePlus 3T Guides, News, & Discussion] :
Did you read posting #3? If that doesn't answer your question, it gives you valuable information wich aspects of your current setup need to be considered.
[OnePlus 3T Guides, News, & Discussion] MD Rana:
Well there's nothing written about open beta ROMs so should I consider open beta ROM as regular OOS?
[OnePlus 3T Guides, News, & Discussion] :
No. Since this is a stock oos rom zip, all oos restrictions and recommendations for changing from openbeta (not to be confused with community-beta) still apply and doesn't need to be repeated. If your setup (bl status and recovery matters as explained in #3) is copletely stock, just follow straight forward Oneplus directions for switching from openbeta back to stable.
[OnePlus 3T Guides, News, & Discussion] MD Rana:
Yeah about the beta to stable part, currently I'm on Oreo beta. Should I go to Oreo stable first then Pie stable or just directly to Pie stable from Oreo beta?
[OnePlus 3T Guides, News, & Discussion] o-l-a-v:
You'll loose data anyways when going from beta to stable, so no point in doing incremental updates. Go straight to latest Pie stable full ZIP. Wipe everything you can from recovery before flashing.

If I were you though, I'd rather go for Lineage OS or other actively maintained 3rd party ROM. Latest Pie stable is already outdated on security patches and won't get more updates.
[OnePlus 3T Guides, News, & Discussion] :
That's the wrong question. Since you need to clean flash anyway, it just doesn't matter. If you would have read the OP, you would know it's important to know your bl and recovery setup (which you constantly don't give), to tell if factory resetting is sufficient, or if a format of data is needed.

Hi

flashed the same , installation went fine , but after reboot on home screen its showing power off and going back to recovery again , any idea ??

---------- Post added at 11:56 AM ---------- Previous post was at 11:53 AM ----------

BTW , i flashed magisk 20.3 also after flashing rom zip
[OnePlus 3T Guides, News, & Discussion] :
What's your starting setup (especially fw, bl state and fs setup)? What steps did you take from there?

Does it boot again if you flash the magisk uninstaller?
[OnePlus 3T Guides, News, & Discussion] AKHIL.cochin:
reflashing rom again makes it work fine

tried latest magisk and older versions also , no luck on flashing magisk reboot completes and showing powering off .

works fine without magisk !!
[OnePlus 3T Guides, News, & Discussion] :
Since you can always flash the magisk uninstaller, you can try magisk 20.2, beta or canary. I always prefer flashing magisk after a reboot to system (on clean flashes after running through first time setup), maybe 20.3 works if flashed now after you've booted the rom once.
[OnePlus 3T Guides, News, & Discussion] AKHIL.cochin:
unfortunately its not working , flashed rom again , worked for few hours , then flashed magisk again same !!
[OnePlus 3T Guides, News, & Discussion] :
Which versions of magisk did you try? What's your bl state? Which version of twrp are you using? Any mods? Did you clean flash, when updating from oos 5.x to 9.x?

If you read through this thread you'll see many users successfully run magisk.

guys I'm using RR rom, rooted and TWRP..

When I'm trying to install this OX 9.0.6 following "For Custom ROM Users with TWRP Recovery" instructions... I got bootloop... what's the solution for this??
[OnePlus 3T Guides, News, & Discussion] :
Too less information.

File system setup (for system, data and cache)?

Fw version?

Rr version?

Bootloader setup?

TWRP version?

Does it boot if you don't use magisk?
[OnePlus 3T Guides, News, & Discussion] BillGoss:
If your phone was unencrypted, then OOS will re-encrypt your phone when it first boots. Depending on the amount of data you have this could take a very long time (15 minutes).
[OnePlus 3T Guides, News, & Discussion] AKHIL.cochin:
already in 9.x previous build

tried magisk 20.1 , 20.2 , 20.3

twrp is twrp-3.3.1-1
[OnePlus 3T Guides, News, & Discussion] :
Obviously something's strange with your setup. Dirty flashing from 5.0.8 to 9.0.x can lead to issues triggered by later updates. Bl state matters too. As well as mods.
[OnePlus 3T Guides, News, & Discussion] AKHIL.cochin:
am not dirty flashing from 5.x man , am in 9.0.5 dirty flashing to 9.0.6
[OnePlus 3T Guides, News, & Discussion] :
I'm understanding that you are currently updating from 9.0.5 to 9.0.6 since your first posting. Reread my postings. If you've dirty flashed from 5.0.x to 9.0.x this may seem to work, but an later update from 9.0.x to 9.0.x+1 can trigger issues that were introduced by the dirty flash from 5.0.x to 9.0.x.
[OnePlus 3T Guides, News, & Discussion] AKHIL.cochin:
from 5.0.x to 9.0.x. made a clean flash only
[OnePlus 3T Guides, News, & Discussion] 123Kage:
I don't have a problem with dirty flash from 9.0.1 xn . My phone is bootloader unlock and non rooted. I just downloaded from system OTA (1.55gb) and installed through that. It was updated via TWRP. I was expected to be factory reset and if that happened I was planned to install Lineage OS 17.1. But it seems good to me so far. No data was lost and no abnormality was noticed. I will stick with this official latest rom for at least another 3 months to let time for Lineage OS to become more stable.
[OnePlus 3T Guides, News, & Discussion] uutucherenz:
Installation failed

********************* For OOS Non Rooted Users with Stock Recovery *****************

1. Download the appropriate OTA from above link and place it in the root folder.

2. Navigate to Settings > System Updates > Settings Icon > Local Upgrade & Select the OTA File

3. Once selected system would prompt upgrade now

4. Select upgrade now and system would reboot in stock recovery and flash the OTA

5. The installer would itself flash the OTA and reboot the device.

The Device will reboot and your OnePlus 3/3T is now running on the latest OxygenOS firmware & OS based on 9.0 Pie

PS: The first boot may take some time so keep calm and wait for it to boot.

I have followed the method above but always failed to update via OTA. The condition of my device is currently unlocking the bootloader and still in stock recovery. What is the solution so I can update via OTA?
[OnePlus 3T Guides, News, & Discussion] BillGoss:
Since this is the last update you'll ever receive, I wouldn't bother with using the ota approach. Just download the zip file to the root of you're sdcard and install it in recovery.
[OnePlus 3T Guides, News, & Discussion] :
What's the version you are starting from? If you start from 5.x you need either to relock the bootloader (which includes a data format) or format data after the update and before the first system boot.

If the update app doesn't show the new update (and you need to download this manually) there's most probably a very good reason. E.g. it's not recommended to dirty update from openbetas (not to mix with community beta) to release versions!

Other then that I completely agree with [MENTION=2911853]BillGoss[/MENTION]' posting.
[OnePlus 3T Guides, News, & Discussion] uutucherenz:
Thank you [MENTION=2911853]BillGoss[/MENTION]. I tried the way you suggest, but every time the install process runs up to 100%, the installation fails.

[OnePlus 3T Guides, News, & Discussion] uutucherenz:
Hai nvertigo67,

Now my device uses version 5.0.8

---------- Post added at 04:37 PM ---------- Previous post was at 04:25 PM ----------

I'll update again later the error message. I got the update from OTA version 9.0.6
[OnePlus 3T Guides, News, & Discussion] :
If you are on 5.0.8 and the update app doesn't show the update to 9.0.6 automatically, somethings wrong with your setup. Let's wait for the error message and the md5 check, but I'm afraid you need to reset your device via unbrick tool to re-enter the standard update path.
[OnePlus 3T Guides, News, & Discussion] uutucherenz:
After the update process has been 100% install process always fails. Sorry I can't attach a picture in this forum
[OnePlus 3T Guides, News, & Discussion] :
Use an external link or write it down (It's only text anyway). Based on the insufficient information: unbrick tool and update from there with the update app. If that doesn't work: rma to oneplus.

EDIT: did you check the md5sum, meanwhile? (Should be one of the first actions if flashing something fails.)

---------- Post added at 15:07 ---------- Previous post was at 15:02 ----------

Factory reset should be sufficient. fw doesn't get unstable and needs "refreshment". This idea seems really strange, farfetched and ridiculous to my.
[OnePlus 3T Guides, News, & Discussion] StressFull:
My issue is not to loose my configuration, my apps, etc and be forced to reinstall everything. Will factory reset guaranty this ?

The story is that I installed a WiFi module, uninstalled it and all of a sudden my 4G is gone, I have only H+...

Anyway, thank you, "strange and farfetched" was enough- thank you...- "ridiculous" was maybe... farfetched ????
[OnePlus 3T Guides, News, & Discussion] :
As a matter of fact the fw partitions won't be altered. Boot partition is altered by magisk. System partition isn't altered but overlayed by magisk. Data is the place where user initiated altering is done. As a consequence the reason for instability is most probably in data (which is wiped by factory reset. To undo all chanhes that may introduce instability (but magisk; needed to stay with twrp), uninstall all magisk modules, boot twrp flash magisk uninstall zip, factory reset and reflash magisk.

If you just reflash rom and magisk, you replace the fw partitions with the same content, restore the boot image (which requires the magisk reflash) and replace the system partition (which you should know, if altered).

Replacing the unchanged parts and keeping the user altered parts to eliminate an user introduced instability is - at least - a bit ridiculous to me. I havn't meant to offend you.
[OnePlus 3T Guides, News, & Discussion] StressFull:
Thanks a lot and no offense taken.
