I am running the last official cyanogen OS build on my opo.
It has a locked bootloader and i wanted to know if unlocking it will wipe internal storage?
I unlocked my op2 and nothing was lost.

No, you will not loose the OTA update. I did it and I got the first update.
after the ota update i lose root, twrp and BTL return locked ?

You will most likely lose root and TWRP, but your bootloader should remain unlocked.
thanks guys, last question there is some risk to unlock the bootloader ?

If you're worried about bricking the device, the risk is very low. All you are doing is simply typing "fastboot oem unlock". It isnt meant to be anything dangerous or risky.
In terms of security however, there are some risks. If your bootloader is unlocked, a thief can easily flash a recovery and pull your potentially important and private information/data. Although the likelihood of the thief knowing how to do this is very low.
Sir will this guide also work for Oneplusone on cm13-Incremental-OTA-Official?
searching everywhere but couldn't find any guide to unlock bootloader on official Cos13.If anybody has successfully unlocked his bootloader on official cm13 then kindly guide the same to me.
Thank You.

Can I unlock bootloader on 5.1.1 eXistenZ rom?

How can I unlock the bootloader on my rooted 5.1.1 d6603 eXistenZ rom without having to loose all my data? And if that's not possible, then how can I unlock the bootloader period? Does it matter if you're rooted and can you do it while on 5.1.1?

You always lose data when you unlock the bootloader.
It does not matter what ROM you are on or if you are rooted.
Any ROm that works on locked bootloader also works on unlocked bootloader
To unlock the bootloader go here http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
Will I loose root and my dual recovery and if so is there root for 5.1.1? Thanks for the help.

No, (well you shouldn't) as root and recovery are installed to the system. Unlocking the boot does wipe data though.
And if once you have an unlocked bootloader you can always root any firmware on any android version. That's the main reason to unlock the bootloader. You will also be able to delete recovery from your system and have a custom kernel with recovery built into it.

Possible to completely reset your Honor 8? Lock bootloader, reset warning etc

Is there any way to completely reset your Honor 8?
I unlocked bootloader with code from huawei, rooted, twrp etc.
Is there any way to completely restore it to factory default?
I tried unrooting it and locked the bootloader using the tool here on the forum. But the warning is still there when you booted, that its been tampered with and is unsafe etc.
Is there no way to completely factory reset it, like it was when it was new?

I would also like to know the answer. I flashed stock and am now unrooted with stock recovery but still have unlocked bootloader warning screen on start. Tried to relock bootloader with serveral different fastboot commands, no luck!

If u have L09 u should flash stock recovery and then flash stock full firmware B101 and the bootloader should be locked and warning should be gone.
I guess there is an internal counter that is tripped when bootloader is unlocked. Like Samsung's Knox.
I have L04, after updating manually root was wiped and stock recovery installed but was still getting bootloader warning. I booted into stock "erecovery" by holding volume up while booting. From there i restored stock firmware and when rebooted warning was gone. So I am now stock without unlocked warning on boot, YAY!
I unlocked my bootloader and then installed the B131 full update. Afterwards my bootloader was locked again and i had it to unlock again.
-> If you want to completely reset, install a full update and do a factory reset
@whiper: after the bootloader was locked and you unlock again, did the phone a factory reset?

Yes. The unlocking process was the same after the update as before including factory reset.
I think the B131 update includes all partitions so that the unlock flag is overwritten.
After the update all was normal, no data wipe, but bootloader locked. I had to unlock it again and all data was wiped.
When i do the next update i will try an ota version.
(With my Honor 7 i did a full update which does not lock the bootloader, so i think it depends from the partitions the update contains)
Guys, just to make it clear. I have a L04 model. i am bootloader unlocked, rooted and have TWRP installed. Is it possible to relock and go back to stock, but simply flashing the stock L04 firmware? Does Honor 8 have some inbuilt trip to notify that the bootloader is unlocked?

Yes. Just flash the whole firmware using fastboot.

What's the current status of the Pixel?

Hi all,
I unlocked the bootloader, rooted and dropped the purenexus 7.1.2 ROM on my Pixel back when it was all released. At the time people were saying that its about as good as its going to get and then when 8 came along ppl said a rooted Pixel can't be updated to the new OS while bootloader is unlocked and rooted.
Just wondering if someone can weigh in and tell me where we are currently at with Pixel in regards to rooting, bootloaders and OS updates? Can we have an unlocked bootloader, TWRP installed, rooted and run 8.1 with OTA updates now?

You can unlock your bootloader. TWRP and root your phone. You won't get OTA updates, but you can install them manually. Or unroot your phone.

If I was to unroot but keep the bootloader unlocked would OTA updates work again?
Is the old bootloader unlock still valid or do I need to lock it and unlock it using current methods?

question about rooting my OnePlus 7 Pro (before I do it)

I have the TMobile us gm1915 op7pro and my current firmware is 9.5.6 gm31cb
If I follow the root guides here on xda and I download OOS latest on their site is 9.5.4gm21aa and I use magisk on my phone to patch the boot.img and then root that way, will it erase my phone to where I have to start from scratch like a new phone?
To root you have to unlock the bootloader first. Unlocking the bootloader wipes everything.

So I can't follow this guide?
https://forum.xda-developers.com/oneplus-7-pro/how-to/guide-root-oneplus-7-pro-patched-boot-t3931205
It said to download the latest OOS and then just patch the boot.img then fastboot from it, it didn't say anything about the bootloader?
