Can't update Oxygen OS to OREO or other - OnePlus 3T Questions & Answers

Hello All, This is my first post.. Hope I get the help I need .
So the problem I facing was my wifi ic of Oneplus 3t was getting extreme hot (bluetooth never worked , kept searching but in vain ) and due to this it was draining my battery quite soon. I finally decided to get my wifi ic replaced which is pasted on motherboard. After getting it replaced my wifi was gone and bluetooth returned to life but the biggest issue was solved which was the heat issue.
I had installed custom rom before replacing ic to check whether they can help me cool down my phone.
So later when ic was replaced, I flashed the stock rom with MSMDownloadTool and got success, but after that whenever I tried to update to latest 5.0.4 uptill today, it installed fine but when restarted, it came to ONEPLUS round dots splash screen and after few seconds the dots would stop rotating and my phone would restart. After a few restarts it would come to the same stage and then comes to a screen
"encryption unsuccessful "... Now after a zillion tries I tried updating one by one which is in order
3.2.6
3.5.3
3.5.4
till here right now m on success ... All I want to know is what this issue is .. how can i resolve it ???
Here it goes the update.... as soon I updated 4.0.2 , the rom with NOUGAT. it stucks on bootloop

I dont get it , its booting 3.5.3 and 3.5.4 correctly just all of the later updates give this error... is it because my wifi is not in working condition???

It sounds to me that this may be related to encryption of the data partition.
Are you flashing the full OOS ROM from https://downloads.oneplus.com ?
Are you using the latest TWRP from https://dl.twrp.me/oneplus3/ ?
If you aren't, then try using them.
If you still have problems then I would format the data partition in TWRP to avoid any encryption issues, then flash OOS and immediately flash the patched boot image from https://forum.xda-developers.com/on...y-force-encryption-op3t-t3688748/post74155053 to prevent TWRP being replaced by the stock recovery.
Note that formatting the data partition will wipe your internal storage and you'll lose all files on your phone.

Yes I flashed full rom... But the problem is just two roms go successful on my device. Rest of the roms no matter if I update them or flash fully they will get stuck on oneplus logo and then restart...

Give it a few minutes - it may be re-encrypting the data.

Oneplus 3T stuck at Android logo screen after xposed module install

Hi guys,
sadly I'm not able to boot into my new OP3T after installing a few xposed modules (gravitybox, youtube adaway and minminguard).
TWRP install and rooting was done without any issues. Then I installed xposed and the modules, rebooted and was stuck at the animated logo with the red and white balls.
After that I tried restoring my backup that I did after installing TWRP but that didn't worked out. Now I'm stuck at the android logo screen and slowly getting depressed
Haven't found any solution in the other threads. Does someone pls have an idea? :crying:
best regards,

Which one of OS you installed in OP3T ? OOS 4.01 ? Or OOS 3.5.4 ?

assuming you have given up on trying to save the data, just wipe and do a clean install. the full zips are here on XDA. I would recommend going with the Blu_Spark TWRP as it saves you from having to jump thru the hoops of the official TWRP. I installed in and 4.0.1 last night in like 3 minutes flat.
https://forum.xda-developers.com/oneplus-3t/development/kernel-t3516012/page28
Thank you for the reply!
Currently I'm struggeling to get any data on to the phone as my phone is not listed with adb devices, so I can not push anything.
Installed the latest fastboot and adb version from Google.

did no change, therefore the version out of the box - 3.5.4
I suggest installing the full 3.5.4 OTA zip. It can be transferred to internal storage with TWRP. When you are in the recovery go to mount, mount USB storage to transfer the needed file.

Phone became problematic and asking to decrypt data!

Everything was working great yesterday after I flashed the new 5.0 OOS through TWRP.
But this morning it was like my device suddenly decided to act funny. First it started FCing different apps all the time.
Then it got into a continuous restart loop.
Finally when it settled, I discovered all these problems:
- Home and recent buttons not working
- Developer options were empty
- Factory reset not working
- When I tried to reboot into recovery, I was asked for a password for decrypting data under a Mount title. I entered my pin and continued with some info for updating partition. I reflashed the stock 5.0 rom and the bluespark v.8.54 recovery, wiped cache, but nothing changed.
Any ideas?
Are you on the recommended version of Blu_Spark TWRP, which is v50?
Have you tried a complete clean flash of OOS 5.0, and not install any add-ons such as Magisk or another root method?
Did your phone usually request the PIN on boot?
Have you flashed anything else that may cause conflicts, such as V4A or any other mods?

No other mods, except naptime and AKT profiles that were running since OOS 4.1.5
Anyway, I decided to factory reset my device so I booted to TWRP recovery and wiped data. This didn't work out very well as the device couldn't finalise afterwards the setup wizard, where it's asking about which sim to use for calls/sms/etc.
Then I had 2 wipes of cache and it seems that everything was back in order. Now I flashed back Magisk and still everything looks good.
My TWRP version is the one that I have mentioned at my previous post. I thought that was the recommended version.

Everything looks fine now? Because when you said the device couldn't finalise the setup process, it may have been a corrupt flashable package. But since it's fixed now, that doesn't seem like the issue.
Sorry I was misinformed about the TWRP version, I thought there was only one version of TWRP by blu_spark that can be used. Turns out, there is another. Sorry about that.
Cheers!
Yee I hope the clean install did the trick.
Although 2 days ago everything was also running great before the catastrophic behavior.
And the worst part is that I have no clue what caused this. I didn't mess with root settings or new apps, had stock kernel installed and no new apps were installed recently.

Flash oxygen os 5.0.5 on OP3T with magisk using TWRP ??

Hello friends..(I am a noob )
Actually I was running on Oreo 8.1 lineage os 15.1 but then I wanted to flash oxygen os 5.0.5 stable ROM I searched for the thread on XDA and then followed it..
Here is what happened:-
1---First I clean flashed the ROM (oxygen os) using TWRP 3.2.3-0 successfully..
But then when I tried flashing magisk 17.1 my phone RESTARTED in between of magisk installation process...??
2--Then I tried it using Blu spark recovery
The same issue occured..
3-- then I tried flashing firmware 1st then OOS
Same issue occurred now my phone vibrated vigorously..
4--when I tried to just flash OOS
It again restarted...
5--Now I want to know how can I flash oxygen os with magisk using TWRP recovery ????
I had tried this process using magisk 14.3, 16,17,17.1
But none worked
Plz help me..
I always use bluespark recovery, I have flashed all Oxygen updates and magisk and never had such problems.
The restart is happening suddenly,in the middle of the flash or after it has finished?

How did u flash OOS using Blu spark ??
2 days ago I just did the same (flash firmware, OOS 5.0.5 stable then magisk using TWRP 3.2.3)
At first I flashed magisk v16, then updated to v17, and here's where I encountered a problem, it keeps boot looping at the boot animation
But I solved it by just wiping data and repeat flashing the ROM & everything else
Just make sure none of the files are corrupt I guess, and wipe clean everything including internal storage (after backing up)

There is no reason to wipe internal files during flashing of new roms and Magisk latest version is 17.1, not 17 which was causing bootloops.
So your post is totally wrong and better next time be careful of what you are writing.

OP said something about a clean flash, so he probably already cleared his data. So it shouldn't be a big deal if he does it again.
When changing from LOS to OOS you should always clear data anyway.
I think you might not be wiping everything before flashing. If you have a computer, I would follow this steps (assuming that you already backed up all your photos, documents, etc):
1- Download the factory image to your PC
2- Wipe EVERYTHING in twrp (through the advanced option)
3- Reboot to recovery
4- Connect your phone to the PC and send the factory image zip to the phone just like with any other usb drive.
5- Flash the file through twrp and inmeadiately flash latest magisk
6- Reboot to recovery and do a factory reset through twrp.
7- Reboot and be happy.
One or more of those steps might be unnecesary, but I always do it like that and it always works...
Have fun!

Help getting from LineageOS 14.1 to OxagenOS 5.08 (Something wrong with flash mem?)

Hi,
maybe someone here can help me or point me in the right direction for a guide. That would be much appreciated!
I have a Oneplus 3T (A3003) that I flashed to LineageOS 14.1 with Magisk-Root a while ago.
I have been stuck on 14.1-20171005-NIGHTLY-oneplus3 for a while now, because since then, whenever I tried to do a nandroid backup from within TWRP, the backup failed because of some kind of error on the data partition (I believe). I haven't flashed a new version since then and haven't come around to it until now, because everything ran very smoothly. :silly:
Since I would like to switch to a more modern ROM (I was thinking of going back to Oxygen OS (5.08)) I started playing around with it yesterday and noticed that TWRP (I think 3.2.0) would not start anymore. It will always get stuck on the logo screen.
I then tried to flash a new version (3.2.3.1) through the Official TWRP app. It still got stuck on the logo screen and I tried flashing 3.2.3.0 after reading about problems with 3.2.3.1 but the results were the same.
Can you please tell me how to get TWRP working again and how to flash OxygenOS 5.08 on my 3T or point me to the neccessary guides?
Thank you.
Data about the phone:

As OOS implies enforced encryption of data partition, going to an from it can be a bit tricky. Simplest way is by wiping using Qualcomm factory restore tool and then just OTA upgrade or flash latest OOS zip.

@r_wraith, I'm thinking that your data may be formatted f2fs and be encrypted but no on-boot password, and have a lot of data in your user data. This could cause a long start time in TWRP.
So try waiingt for about 5 minutes when you boot into TWRP. It may end up getting past the logo screen.

That worked, thank you. Yes, my data partition is/was encrypted.
Since TWRP seems to be working again, do I need to flash some kindof firmware upgrade before I flash Oxygen OS or is this included in the OxygenOS-Image and only needed for flashing ANdroid 8 Custom ROMS?

The OOS zip includes the firmware. Custom ROMs don't because they use the OOS firmware. The firmware is stored in separate partitions so it isn't affected by wiping the system and data positions.
Since you're coming from Los 14.1 you'll need to do the following in TWRP:
- take a backup of your current system
- do a factory reset to clear the data partition without losing the files stored on internal storage
- flash the OOS zip file
- flash Magisk 18.0 which will root the phone as well as prevent TWRP from being replaced by the stock OOS recovery

Problems with flashing OOS 9.0.5 or 9.0.6

Hi everyone!
I am currently using android 8 with Oneplus 3T. I've used 9.0.5 once before when it had problems with battery usage so that's why I downgraded back to 8 to wait for the 9.0.6
Now, when I try to flash the new OTA or full package, my phone gets stuck to boot. It does not restart but just stays in the boot animation, same with 9.0.5. Only solution to get the phone back to work is to flash android 8 and therefore wipe the whole phone.
If I try to update via settings it doesn't restart the phone when clicking "upgrade now".
Here's logcat when pressing "upgrade now":

I'm not sure what is wrong with the phone. It seems like the settings update app doesn't have permission to reboot phone. Verification and MD5 for the update package should be okay. Is it something to do with the unlocked bootloader or data encryption or what? This is the first time I have this kind of problem.
Before trying to install 9.0.6 I wiped my phone completely and formatted data etc. I've also tried to downgrade TWRP from 3.3.1-0.
Anyone have any suggestions of what should I try to do?
A little heads up to save you time in the future. You will always get high battery usage when upgrading firmware, it can take everything from one day to one week before the OS settles after an upgrade. Also it's very common to stumble on some battery drains caused by failed upgrade scripts having processes hang or loop which csuses drain. Therefore it's always best to upgrade and clear data to avoid such bugs, and then wait for the OS to settle before you complain about battery drain/capacity issues.

You say you're running Android 8 which could mean you're running any variety of ROMs.
If you aren't running OOS then flashing the OOS 9.0.6 (should use the full zip) then your phone won't boot unless you wipe the data partition (factory reset).

There are too many possibilities as to the problem depending on what you've done.
So, can you get back to a point where your phone boots successfully? Once you've done that, then tell what rom and version you're on and whether you're phone is encrypted or not.

Hi! After wiping and flashing the stable OOS 5.0.8 (android 8.0.0) the phone works fine. Phone is currently encrypted and if I remember correctly it has always been encrypted while flashing.

Thanks for the info.
With an unlocked, encrypted phone running 5.0.8 then flashing 9.0.6 will not boot unless you remove the encryption first. To do this you use TWRP>Wipe>Format data. And you'll lose all data on your phone.
If you don't want to lose all your data then you can flash 9.0.6 rom and then, without rebooting, flash the modified 9.0.6 firmware from https://forum.xda-developers.com/on...-5-0-8-firmware-barrier-t3941164/post79758055
Then you'll be able to reboot normally. You don't need to flash the modded firmware again, even if you change ROMs or restore an OOS backup. However, if you flash the 9.0.6 rom again, then you'll need to flash the modded firmware again.
If you're rooted, don't forget to flash Magisk after flashing the 9.0.6 rom (before or after the modded firmware makes no difference).

I tried both of your methods but still just stuck at boot. If I flash the full 9.0.6 rom in TWRP (after formatting data) it states that "no OS installed, do you want to reboot?" and then just gets stuck at boot.
I've also tried to flash modified boot image after ROM to remove forced encryption but still no change...

1. starting from a working phone (which in your case is OOS 5.0.8)
2. Download https://github.com/nvertigo/firmwar...3t/oxygenos-9.0.6-bl-km-5.0.8-firmware-3T.zip
3. if you're not using the official TWRP 3.3.1-0 then download it from https://dl.twrp.me/oneplus3/ and install it using fastboot (I assume you know how to do this).
4. make sure the md5 of you OOS 9.0.6 full rom zip is e4e46aa9eebffdd485071383dcda4218
In TWRP:
5. take a nandroid
/backup of your working rom
6. do a Wipe>Factory reset
7. flash the full OxygenOS 9.0.6 rom
8. without rebooting(!) flash oxygenos-9.0.6-bl-km-5.0.8-firmware-3T.zip from step 2
9. reboot
If that worked, then
10. flash TWRP using fastboot (it got replaced when OOS 9.0.6 booted)
In TWRP
11. flash Magisk 20.1 and reboot
You should now have a clean 9.0.6 rooted installation.
if you get to this point then we can look at restoring your app data if you like.

I got android 9.0.6 finally working by using recovery tool to restore my phone back to 6.0 and installing updates one by one until I got to 9.0.6. Now I got root and recovery and stuff working!
Still, thanks for your effort although the real mystery of why I couldn't get it working in any other way stays unsolved...
