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.

[Q] Ota with unlock bootloader, root and recovery

hi, i have a noob question. I'm not a true noob but i never had a "nexus".
Today i unlocked bootloader, installed twrp recovery and rooted my device. Then i flashed only franco kernel to try new screen firmware update.
So i'm stock with cm11s without kernel.
When an update will be released,unchecked CM recovery update, can i update or i have to unlock bootloader again before?
after updated iìll be with bootloader lock or unlock?
Thanks to everyone

The OnePlus One is not a nexus device but it is very close to being one.
No you do not have to relock your bootloader, leave your bootloader unlocked. There is no point in relocking it unless you're doing warranty.
Just untick "Update CM Recovery" in Developer Options if you haven't already. You can flash the new OTA with TWRP.

Hi guys.
I'm also having some questions about the OTA updates and the root/bootloader.
Currently i'm still having the 25R, i unlocked it, rooted it with TWRP, all fine.
I've been using Nexus 4 before, and after lots of Roms i kept using CM for a very long time, so normally i just updated it, and i was still rooted and everything.
But now i keep reading that you will lose root and bootloader if you update the CMs (with OTA?).
So then i have to unlock and root again, so i will need to wipe all data again?
Or is there a simple method to just update and still keep all root etc?
greetings

Nothing will happen to the bootloader. If root is lost after applying OTA, just reflash SuperSU. You can apply OTAs using TWRP.
No wipe needed.

Should I re-lock the bootloader?

Hi everyone,
I have D6603 with with Android 5.1.1 (23.4.A.0.546) with an unlocked bootloader (done per instructions on Sony's website).
For a while now I've noticed that the device overheats when I use the camera for a few minutes. According to this article,
the new update Sony have released, is supposed to mitigate the problem.
I cannot update my phone to the new Android version, because of the unlocked bootloader.
Can/should I re-lock the bootloader? Or is there a way to stop the overheating issue?

You can still update to the latest firmware with flashtool.

Thanks for the info Beetle. May I be so rude to ask you, where I can get the most up to date flashable ROM?
I did unlock the bootloader, but never managed to install a recovery mod or get root.

In flashtool theres a button labelled xperifirm, if you click that and follow the instructions you can download a ftf directly.
As for root and recovery, you can use this guide http://forum.xda-developers.com/z3/general/guide-rootrecovery-how-to-root-install-t3017056 , and then create a pre rooted 5.1.1 firmware from here http://forum.xda-developers.com/crossdevice-dev/sony/tool-prfcreator-easily-create-pre-t2859904
Or you can install androplus kernel http://forum.xda-developers.com/z3/development/kernel-andropluskernel-t2925999 after you upgrade to stock 5.1.1 with fastboot, and skip the whole downgrade to kit kat which would be alot quicker.

Wow, that seems easy enough. I'll try it later tonight. Thanks again!

No worries, good luck. You may have to disable virus protection to download xz dual recovery installer, well, I have to anyway, my VP doesnt like the install.bat file.

EDIT: isn't the .546 the latest?

Not sure... My phone tells me there is a system update, but it always fails because of the unlocked bootloader.

Relock bootloader for warranty

Hi, is It possible to relock bootloader for to have warranty back?
Thanks

once you flash the stock img, it will be locked again.
Till Nougat, we had dload method which locks it fully (other method for unlocking it would just re-lock it)

Hey, i am in the same situation and after flashing the stock rom + stock recovery my bootloader is still unlocked, and i still get that "This device has been unlocked and can't be trusted" screen on boot.
Is there any way to manually lock the bootloader?
Edit: i found this SRKTool and i was able to easily relock the bootloader. You need the Unlock code though and it resets your phone, so backup your data.

Yes it will only relock the bootloader but not lock. Anyone experienced with this can get this that you had unlocked your bootloader earlier

Many people say that if we flash stock rom the bootloader stay unlock. Or i have to flash in a particular mode?
With the tool i can relock but not lock, right?

Yup

i Read somewhere that if u flash the stock rom using dload after u have relocked the bootloader, the bootloader status will change from relock to locked. does this work? can anyone try and confirm this? i want to make sure of this before i unlock. I would be greatful forever.
Thanks

No I haven't even unlocked the bl yet. I just wanted to make sure it the relock to lock state was possible before I unlock. I will do so soon when I get some time.

Yes you can always do via full ota or flashing the stock firmware via dload. Not hard to do to retain warranty:silly:

Use the first file, update.zip. it will contain a update.app file around 3 GB. Can use this single file.

Really? And I have to install over the same firmware, not an update? For example, now I'm on 162 build with unlock bootloader. If I install only update.zip of 162 build with dload method, I obtain the lock bootloader?

Why you want to relock, to gain warranty?
If so, better dload the current firmware and it will lock it safely.

because, i dont want to see everytime when i reboot my phone,this stupid message, who tells me that i have unlock bl...
i have 8.1.0.151 (c432)
i was downloaded this version when im trying to rebranding.. for official site..
if i relock with this version, the worse scenario it will be...??? brick???
if i dload the current firmware, i will install it with TWRP again? and after it will be locked safety?
and what firmware i must to dload?

Question unlocked bootloader OTA ?

Hello, I'm going to unlock the bootloader to root, I would like to know if it continues to receive and install OTA updates even unlocked.

Unlocked yes rooted no. Not unless you restore stock images then direct install magisk to active slot after ota installs.
