i want to download custom boot so i should unlock my bootloader first? cuz in the first place i said i should unlock but then sm 1 told me its ok you shouldnt unlock the bootloader
If you mean the bootanimation, you won't need to unlock the bootloader, look at how some custom Roms with custom bootanimation are structured and try to make a flashable zip with the one you want.
Sent from my R800i using XDA
Seems like he means he wants a custom ROM.
Some ROMs require a new kernel, so the bootloader needs to be locked.
Other ROMs can be flashed using a Nandroid restore in CWM that others have created. This method does not require an unlock
hi sorry for noob question.
i rooted my phone a while ago, and i think i remember unlocking bootloader but im not sure. i DO have TWRP recovery, does that mean that i had to unlock my bootloader to get it; thus it is unlocked?
thanks!

Since u r rooted and already have custom recovery flashed,there's no need to do anything else..u can now flash custom rom of ur need via recovery.
International Samsung devices have an unlocked bootloader when you buy it.
So it's necesseray but already done by the manufacturer.
How do i unlock my bootloader on Samsung Galaxy S3 SGH-i747(AT&T).
So i can install some ROMS.
The boot loader is not locked. You need to install a custom recovery for your phone.
Oh ok,I already have a Custom Recovery.
So i can install it directly now...
Thanks to ur reply though! :good:
Any one knows how to re-lock the bootloader of one plus 3???
And
How to remove that screen on boot up after unlocking one plus three??? :/
If you read the screen properly ull see the instructions on the screen itself do everything the same way you unlock the bootloader just instead of oem bootloader unlock type oem bootloader lock ...but make sure you're on stock rom and recovery

But then My root access will be wiped??
I want root access and dont want than annoying screen
two questions different answer but I would bet if there is a way to remove nag screen a google search would find it. Keep searching threads
there is no reason to re-lock bootloader, its still under warranty through Oneplus even with unlocked bootloader. but if u really want to
1. fastboot flash stock recovery (fastboot flash recovery recovery.img) (make sure u download the file, its somewhere here on the forums
2. reboot and then reboot to fastboot (fastboot oem lock) (i have never re locked a bootloader so i am not sure if it will rewipe ur device again like unlocking it does)
3. boot to OS and get developer options again and uncheck OEM Unlock (do this last)
i would not recommend re locking since it wont void warranty and seemed like a lot people screwed up their devices relocking it, but they also unchecked the oem unlock before flashing stock recovery, also i am not sure if step 2 is needed, i would just make sure u flash stock recovery 1st before doing anything
HELP

What part of be on stock OS is so hard to understand?
If you're not absolutely stock when relocking, you will brick your device.
Then good luck trying to enable OEM Unlocking when not being able to boot.
As someone who messes with their phone, relocking your bootloader is one of the worst possible things you can do.
If not done correctly, it WILL brick your device.
If you want to go back to stock, then surely do, there is absolutely no need to relock your boot loader unless you're selling your device to someone or if you're looking to pass SafetyNet for Android Pay or something.
Also, you cannot have the cake as well as eat it. You need to have an unlocked boot loader for root, exposed, etc. There is no way around this.
Phones previously had to be reverse engineered and exploited to gain root access, now OEMs freely allow unlocking.

I hope you can read this. I'm not a noob and I am looking to relock my bootloader because I am going to sell it. The person wants it fully stock so I need to relock the bootloader in order to regain access to official Ota updates.
I need to be on complete stock (stock recovery and rom) right? Would you please kindly point me to where I need to go to download the stock Rom and recovery. There's some TWRP flashable OTA zips on Oneplus forums that restore stock Rom and recovery but I want to be sure that that is enough and that I don't end up bricking my device for something as stupid as this. Any help would greatly be appreciated!

Fash 3.2.4 FW from here.
Follow all instructions from here (except I would suggest sideloading the StockROM before relocking).

I followed the same guide posted on OnePlus Forum to re-lock my bootloader. Just follow them, it works.
Here is that link from OnePlus forum.
1. I restored my stock rom backup from TWRP
2. Flashed Stock recovery
3. fastboot oem lock
4. Sideload stock ROM
Done.
I unlocked because stock ROM I felt was much stabler and hassle free. Have rooted and played with custom ROMs enough in my Nexus 5 days. Just too much stress and can end up with non-working features. Might root again in future if I find something compelling in custom ROM.

If you unlock bootloader and root device. Do you still get OTA updates if you stay on stock ROM?

If you unlock device, you will still be able to apply OTA. If you rooted by modifying the /system partition, OTA will fail, but if thou rooted using systemless method, you can apply OTA.
Iam on stock OOS 4.0.3 and i was plagued by the same error
--adb sideload the complete rom (with locked bootloader)-- method worked for me.
Previously i had unlocked bootloader and was on freedom OOS 2.3 with TWRP and then i realized that stock updates are better.
So i installed stock recovery and and tried to flash Stock Firmware 4.0.3 through sideload command and it failed.
then i installed TWRP and then installed stock OOS 4.0.3 and it installed fine but with some error.
Then i installed stock recovery
So i rebooted it and after long time it was installed but then i started getting dm_verity error and also i was frustated with unlocked bootloader message.
So i locked my boot loader first from fastboot oem lock and then sideloaded the stock 4.0.3 again and it really worked.
So now i am on stock rom and stock recovery and no more dm_verity error or unlocked bootloader msg to wait for 5 secs...
Now iam really loving my Oneplus 3..
So i get this idea i don't even know where. So first step is to get root access. Like kingoroot that can done this on device without bootloader unlock. Than i'd use TWRP app to flash recovery and lastly flash a custom os. I really dont know if it will work but i will definitely try this sometimes
Or just flash factory firmware without needing root or the bootloader unlocked...
