Is there an official backup I can make of my current installation without installing custom recovery ?
I want to try out Android P but I don't want to root or do anything with my phone. Not even unlock boot loader before I do backup. Any way to backup phone in my current state and then enable OEM unlock, unlock boot-loader and install custom recovery. Cause I am positive I'll use if for about 20 mins and then go back to my stable 8.1
Catch 22
You'll need to unlock your bootloader which will wipe your data partition so sadly I don't think it's easily possible.
To be able to take backups and restore you will need a custom recovery, be already root and have an unlock bootloader

Has anyway found a way to Root the OnePlus One without having to flash a custom recovery with the new 33R OTA?
(yes I didn't check the CM recovery)
*But after I updated to the 33R update I still had root access intact, despite gaining root by boot and not having unlocked the bootloader under 33R. The problem was I did a factory reset and obviously it reflashed the newer bootloader and I lost root access (yes stupid)
This can no longer be done 'fastboot boot twrpimgname.img' with the 33R update ;
Aren't One Plus all about give you the power so why did they go ahead and block boot custom recovery that worked before ??
This is the under 33R OTA =
C:\adb>adb reboot bootloader
C:\adb>fastboot boot openrecovery-twrp-2.7.1.1-bacon.img
downloading 'openrecovery-twrp-2.7.1.1-bacon.img'...
OKAY [ 0.402s]
booting...
FAILED (remote: Device not unlocked cannot boot)
finished. total time: 0.404s
Seems the have patched being able to boot a custom recovery without unlocking the boot loader
Yes I realized the the 'Update CM recovery' option but not after I updated to 33R (my oneplus was rooted without having to unlock the boot loader)
I did do a Nandriod backup of course before the 33R OTA.
The nandriod backup is rooted without having to unlock the bootloader via this ' fastboot boot twrpimgname.img '
Is their no way yet to boot a custom recovery without unlocking the boot loader ? Does one have to wait for a update twrp recovery to boot not flash ?
The question is: WHY?
the locked bootloader is locked because it allows only booting a signed recovery, if you use a custom-unsigned-by-manufacturer recovery there is no sense in keeping the bootloader locked.....
OnePlus knows that 90% of the users are rooting and unlocking, so there is no sense to keep it unlocked.... in case of necessity, you can relock the bootloader !!!
Anyway, you wrote in the wrong section !!!

What area is the right one, my bad.
Also asking if their is a way around the 33R to boot custom recovery
Why though?? You don't need to boot to a custom recovery. Just unlock the bootloader, it doesn't void your warranty. You have absolutely nothing to lose by doing it, and absolutely nothing to gain by leaving it locked.

Just an innocent wipe... and he only wants root.
Yeah and the right way to get root is to unlock your bootloader, install TWRP, and flash SuperSU.
Back stuff up, unlock bootloader, restore stuff. It's stupid to try to 'hack' into the world's easiest phone to root.

How's he meant to go back without an unlocked bootloader??
Transmitted via Bacon
As the Title states, I'd like to know if I can do a data backup via the stock Android Recovery, since I heard that Unlocking Bootloader would lead to a data erase. So I was wondering if whether I could restore the backup after unlocking bootloader and have my data intact (It ain't my phone)
I'm not sure but you can make a backup and place it on a computer and then unlock the boot loader and restore it when you are done with all the things.
Use carbon/helium.
So I see
I unlock the bootloader to install twrp and magisk, it's possible to lock the bootloader again without problems or the phone don't boot?

Locking you bootloader while TWRP and Magisk are installed will give you a guaranteed brick. Use a Fastboot Rom to return to stock, then you can lock it
If you want to keep TWRP and root, do not lock the bootloader. As the user mentioned above, you'll brick your device.
if i flash stock rom, than is that ok to lock the bootloader ? and how to lock it ?

If you flash a full stock rom then yes. All you do is use the fastboot rom we talked about earlier, let the phone boot up (don't bother completing the setup process, just let the phone boot up), restart to bootloader, and use the following command from the command prompt on your pc:
Fastboot oem lock
It will give you a menu on your pone asking if you want to lock the bootloader. Tell it yes. It will then lock the bootloader, factory reset the phone, and then boot up normally with the bootloader locked. It's that easy.
ok thanks.one question. is that important to flash the stock rom using fastboot only ? or can i flash it using twrp ?

I did it through twrp, worked just fine. Make sure to wipe beforehand though, don't want to risk bricking your phone

Doing it with a Fastboot Rom will guarantee that things needing wiped will get wiped. When returning to full stock I will always recommend the Fastboot Rom just because of how it completely handles everything it does flawlessly. I imagine flashing a full rom in TWRP will work but I have never tried to return to stock this way
i did try stock using twrp and it was perfect
I have unlocked bootloader but in the end NOT installed TWRP or root (just wanted to test if i can live without it and still be able to install without wiping everything)
Now I just want to lock bootloader again for selling device.
Can I do so with simple fastboot command "fastboot oem lock" without bricking phone?

Use msm download tool to be sure. It will however wipe all.

You can, but if you are selling the phone I would still use a fastboot rom just to be sure everything is wiped and no data sensitive to you is being sold along with the phone.
Thanks a lot for the shared info here. This is just what I need and had been asking myself for quite some time now.??
So never lock bootloader with twrp and magisk installed.
I was experiencing some minor glitches the past couple of weeks after taking the Android 10 OTA, so I decided to a factory reset and flash the Android 10 image. I had to unlock the bootloader to do that of course.
Now I'm realizing I need to re-lock the bootloader so that it's not in this insecure state. However I'm reading that re-locking the bootloader wipes the device (which returns it to Pie?) I'm also reading it can brick the phone if custom data is written.
When exactly do I re-lock the bootloader to preserve my clean install of Android 10?

If you're completely stock you can lock the bootloader. Before you do i would make sure you can boot into the stock recovery as sometimes flashing an ota in the stock recovery is the only way to recover your device if the bootloader is locked. Locking will wipe your device, but it won't change the operating system you're currently on. So if you're on andriod 10 it'll still be 10 after a wipe.
I have a SM-A530W running Android 9 but is unrooted with a locked bootloader. I want to make as complete backup of the phone as possible, preferably using DD so I get a byte for byte image. Using OEM Unlock will wipe the device, so is there any way to flash a custom recovery or root the phone without wiping it? Or is there a way to get a full image of the device without root? I have full access to the phone with the PIN code and google account password.
