how to wipe clean from android pie - OnePlus 6 Questions & Answers

Just updated from the official updater to android pie. But it was not a clean or fresh install.
If I do a factory reset would it revert itself to oreo or pie? Will it also delete the oneplus switch backup that I made? I want to make a clean install involving wiping the internal storage. Is there a guide?

you reboot the phone into recovery. then do data format. reboot into a clean first boot oneplus-6

Power off your phone, the press power and up together to boot to Fastboot, and power and down together to boot to recovery.

There's several apps in play store, you can put in your dock or anywhere you want. I use easy reboot.

Settings, system, reset, Erase all data. No need to boot to recovery. It will also give you an option to Erase Internal storage.

Cannot decrypt TWRP data - please help

Hello,
I have totally wiped my phone to clean install ROM. However, now TWRP is asking for a password to decrypt data. I gave the password I set but it is showing wrong password. I don't understand, I am sure I am using the right password. Was on Venom 1.7.0 and disabled password on first boot. On the latest 1.27 base as well. Tried fastboot but device doesn't detect on fastboot :/ Not sure what do now, please can someone show me how can I get rid of this issue? Thank you.
Taking from Second Post by Nkk71 of TWRP Thread.
while still in TWRP, use the TWRP File Manager to navigate to /data/system and delete all the locksettings.* files (such as locksettings.db, etc). When you reboot, the password will be gone.
Unfortunately, I cannot access my internal storage. Hence I don't see any files. I don't mind wiping it clean and starting over. Can I downgrade with the help of a RUU?

Try this:
1. CANCEL WHEN TWRP ASK FOR PASSWORD
2. GOTO WIPE
3. SLIDE TO WIPE
4. BACK TO MAIN TWRP MENU
5. REBOOT TO RECOVERY AGAIN

Thanks man! :good: I also stumbled across some "default Passwort" which I didn't know and even after installing new ROM I still couldn't access my device. Even after having wiped cache and dalvik and all partitions. So this second wipe AFTER installing the ROM did the job!

Be careful because this erases everything on the phone and you have to install everything once again
EDIT:
I don't understand if this can be achieved with stock ROM. In case it is not possible: how to flash another ROM if no root access is possible? I just wanted to have a rooted stock ROM. Please help.

I cannot flash TWRP or any Mods

I just got this phone and i have OEM Unlock enabled. I am due to sell my old phone in few days so i am in a bit panic mode right now :\
When i try to flash TWRP along with the instruction that were here (i tried with only applying both or only dm-verity) the phone started to "start" flashing the Samsung logo but nothing happened and after 15-25minutes i tried to install this ROM and it also shows "Starting up please wait" but it also seems to start up indefinately.
Can you tell what is wrong now? It seems i can flash the stock ROM and boot to it but cannot install TWRP/Root nor any custom ROM's :\
Hey bro follow this.
Install stock ROM.
Boot into it once.
And flash TWRP. Disable auto reboot in Odin.
Then boot into TWRP directly from there.
Now swipe to allow modifications.
THEN GO INTO WIPE ADVANCED WIPE AND CLICK FORMAT DATA AND TYPE YES.
After format reboot into recovery once again.
Now again swipe to allow mods.
Now only install Dm-verity.
Reboot.
Now the phone will boot.
Go back into recovery to install your ROM it'll root the phone.

Sorry but still no dice (waited for ½hours to boot)
The data wipe did not even succeed. I attached screenshots of data wiping plus no-verity install if there is something anyone could use. I do not really understand how this is so hard... I have never encountered this kind of problem with common phone.
@DARKKi
Did You try to format data or just to wipe? You should click on format data and type "yes"
Dude I clearly mentioned, you have to click format data in advanced wipe. First try to read and understand then proceed. Click format data and then type yes and then you're good to go.

Damn. Sorry, i think that when going into advanced wipe there is no format there it's under normal wipe so i only thought that it meant that but yeah my mistake. I should have looked for format data and come to my own conclusions :\
Well first result of format resulted on loop boot and i could not even flash the stock rom with Odin (failed directly) but then i tried to flash TGP ROM via TWRP and it worked! So now i am using the phone as we speak!
Thanks a lot njaya95!

[GUIDE] Flashing oreo roms on mi a1 without wiping internal storage.

Hello guys .
This is a guide to flash lineage os 15.1 or any other oreo rom on mi a1 without any fuss, bugs, wiping internal storage. And update it by dirty flashing it. I personally use this method and others have also used resulted in booting safely with zero bugs in the rom, no force closes.
So here you go :-
1- boot to twrp
2- wipe system,cache,data
3- check on which slot you are.
4- if you are on A, change to B (after wiping).
5- boot to bootloader and boot to twrp which I gave.
6- wipe slot B also. (System,cache,data)
7. Don't touch slots and boot to recovery.
8- just flash los15.1 rom from there and nothing else.
9- go to bootloader and again boot to twrp
10- flash gapps and boot to bootloader.
11- again boot to twrp which I gave and flash magisk.
12- reboot.
Enjoy. You have los 15.1 without wiping internal or downgrading to nougat or wiping internal storage.
So now here's the guide to update it. (Dirty flash)
(Remember to remove your pattern, pin, password before flashing or backing up)
1- Backup your data using twrp which I linked down below.
2- boot to twrp which I gave you.
3- wipe system,cache,data
4- check on which slot you are.
5- if you are on A, change to B (after wiping).
6- boot to bootloader and boot to twrp which I gave.
7- wipe slot B also. (System,cache,data)
8- Don't touch slots and boot to recovery which i have
linked down below .
9- just flash los15.1 rom from there and nothing else.
10- go to bootloader and again boot to twrp which I gave.
11- flash gapps and boot to bootloader.
12- again boot to my twrp and flash magisk.
12- reboot. Let it boot completely and skip the setup.
13- boot to twrp i linked down.
14-just restore your data backup and reboot.
Congo you have successfully updated your rom without wiping data and also whosoever is facing bugs like fp not working and other bugs use this method. Everything will surely work.
Anyone who has a problem can message me on telegram. Username- droidreboot

If you're updating none of your apps or data will get erased. But if you are moving from stock oreo to this rom, it's like resetting your device. That's it. ?

You have ro to wipe data if you are changing roms. Like if you are on lineage, and you wanna install resurrection remix then you'll have to wipe system cache data in both slots. And if developer of lineage pushes an update and you're on lineage then you don't have to wipe data. I mean if updating you have to make a backup then wipe. Then after first boot restore that. Don't do this if you're changing roms. You'll get a bootloop

It says if you're upgrading from stock then wipe data. And if you're updating from old lineage build to new first make a backup then wipe and after first boot restore the backup. Read carefully.

after whiping data, phone is stuck and twrp does nothing

Hey guys,
I have a oneplus 6red rooted with magisk and twrp running oreo 5.1.11, today I decided to enter twrp and reset my phone by whiping dalvic, cache and data.
After reboot, phone screen is totall dark but the light indicator was flashing constantly, entering twrp is no succes, twrp screen is stuck like more then 10 mins. I believe that I cant enter twrp to do something about it. I have downloaded the stock 5.1.11 which is an oreo version
Did I do really something wrong ? if yes or no please let me know how to fix this.

Try bluespark TWRP and flash your OOS zip again and report back. Maybe a magisk flash will help too.

thnx, I entered into fastboot mode, then from my pc I when into the fastboot folder to open cmd and boot twrp from there on my device, from there I followed a tutorial how to adb sideload and flash a rom from your pc. Now its working
But I dont understand why a simpel factory whipe through twrp caused all of this, I only wiped dalvic, cache and data.

This may be a side effect of A/B partitioning and no longer having a recovery partition. Remember TWRP is a part of the boot partition now

Use a fastboot rom. That will wipe EVERYTHING - and guarantee that you have a usable phone afterwards

But how are you sure that it was system wipe ? did you factory reset your op6 multiple times without issue through twrp ?

Its the easy answer, say that you wiped system or such.
If you wiped Data with Magisk installed, without flashing the stock kernel, you won't be able to boot, since Magisk stores stuff necessary to boot on Data.
Usually, people is stuck on a infinite bucle on TWRP after this, you couldn't even enter TWRP? that's new. The issue you're telling sounds like you changed slot in TWRP somehow to an unused one or something like that, never heard of that.

Yeah I have wiped data in twrp with no issues. TBH it just sounds like there was no system to boot into. Wiping data is just that and shouldn't make the phone unbootable. Also you fixed the issue by flashing OOS which makes me believe this also. If you want to factory reset your phone the best way is to do it through settings.

[Solved] Help to flash custom ROMs

Hello everybody,
I bought a Oneplus 7 Pro a few days ago and I'm preparing it for my daily usage. It's my fourth Android smartphone, and the third Oneplus. So far, I managed to flash everyone of them, with no major issues.
And then, the Oneplus 7 Pro suddenly appeared
I used this tutorial to unlock the bootloader and flash the custom recovery.
From my understanding, the custom recovery is flashed in the Recovery Ramdisk and available for both A & B slots.
For now, I have A and B slots with stock OSS, unlocked bootloader, custom recovery and Magisk. All of this is working.
There began my problems. I want to flash a custom ROM without Gapps and I fail to do it. All instructions around ROM threads seems different to me, I don't get the thing about A & B slots, when I flash one rom, it boots as usual on the stock ROM, if I flash both slots, It causes bootloops and if I manage to launch the recovery, my internal storage isn't detected and I can't restore any backup.
I already used MSMDownload to restore the phone completely once.
Can somebody explain to my dumb person how to do it proprely ? Thanks in advance ! :fingers-crossed:
TL;DR : I fail to flash a custom ROM and make it work.
Yes I had same issues when rooted, it means you lost root. You can try tool all in one to flash recovery and magesik via fastboot. If that doesn't restore your access, on twrp you will have to type in format, then mount, then add rom to storage(this method wipes everything beware)

For now, my phone is working nicely. But that's the process of flashing a new ROM that fails. Recovery and Magisk are already and working.

When you flash the ROM, does TWRP tell you that if you want to continue you need to reboot recovery ? If so, do you ? Do you reboot recovery on the same slot, or do you flash both ?

Nope, it doesnt tell you anything. Just reboot recovery from reboot menu. Don't touch the slot options
Thanks for your advices.
I'm trying right now, here's my steps :
- Wipe Data, Cache, Dalvik Cache (the standard Factory Reset)
- Install ROM : TWRP logs show that he's flashing on inactive slot A, then B. After that logs said " To flash additional zips, please reboot recovery to switch to the updated slot ". I'm going back on the menu
- Install TWRP Installer like previously
- Reboot Recovery : TWRP ask me if I want to install the TWRP App, I dismiss. After reboot of the recovery, it asks if I want to keep System Read Only, I swipe to allow modifications
- Wipe Data : Can't do it because TWRP is unable to mount storage. And after further investigations, I'm now on slot A, not B as before.
- Reboot recovery to slot B
- Wipe Data on slot B
- Reboot system
And It still booting on the stock Oxygen OS Rom, not the custom one installed before. I'm lost
The problem is that you are not performing factory reset.
Wipe data is not enough,you gotta go to wipe-format data-enter yes and swipe.
That is why you are getting bootloops and twrp unable to mount storage problem.
A/B is pretty simple.
You got two slots for many partitions like system vendor boot and all,but a single data partition.
Flash a rom from one slot,it always gets flashed to the other slot no matter what.So next time you reboot to recovery or system it's gonna be on the other slot.So here is the problem..one rom cannot decrypt data which was initially encrypted by another rom..so you gotta perform a data format instead of wipe.Thats it.

Well yes, I didn't understood the difference between Wipe and Format Data.
So let's resume :
Unlock Bootloader
Advanced -> Install Recovery Ramdisk : Install TWRP
Install -> Flash TWRP Installer
Install -> Flash Magisk
Reboot -> System : Reboot on stock OxygenOS Rooted
Then
Wipe -> Factory Reset : Wipe Data, Cache and Dalvik Cache, that means you just have to swipe on TWRP.
Install -> Flash ROM : Use the install function and install the ROM
Install -> Flash TWRP Installer : Don't reboot, go back and install as the previous step
Reboot -> Recovery : Reboot TWRP and it automatically load the other slot
Wipe -> Format Data : Click and type yes
Reboot -> System : Just reboot and it should load the installed ROM

Not wiping.. formatting..that is compulsory if your current data is encrypted
After multiple tries to verify the process :
