Hi all,
I have a rooted and unlocked Nexus 5. Just wondering if my bootloader will remain unlocked after Lollipop update, either through OTA or factory image. I need the bootloader to remain unlocked in case an unlocked bootloader becomes the prerequisite for rooting forever.
Thanks!

The bootloader will only lock if you specifically lock it using fastboot or an app. No other way

So a locked bootloader remains locked and an unlocked one stays unlocked if I don't change anything in the OTA zip or Factory Image when flashing? Or don't specify it in adb?

Yes. Though fastboot is not adb. two different things
Thanks!
Hey guys i was just wondering if there was any way to flash back to stock without loosing my bootloader unlock?
the only way to re-lock the bootloader is by using the fastboot command for it.
This is an interesting question.
I am currently on the latest 4.4.4 and now I would like to try CM 12.x (5.1.).
In case I do not like 5.1, how do I get back to stock without losing the unlocked bootloader?
flashing back to stock will not relock your bootloader. the only way is by fastboot command. so if you an unlocked bootloader there is no need to worry about losing that. you will however lose root which is easy to get back.
hello guys, im new here.
anybody tried relocking their bootloader by using this command?
fastboot oem lock
and does it work and restores warranty conditions?
That command has been tried since the original Moto G and no, contrary to what some people think you can't reset the internal unlock counter. They will always know you unlocked it. If nothing else, they know because you got the unlock code from them. I'm not sure why people overlook this clearly posted sentence when they request the unlock code from Motorola.
"Unless you have a Developer Edition device, once you get the unlock code, your device is no longer covered by the Motorola warranty; in other words, please don't blame us if things go wrong, even if they appear unrelated to unlocking the bootloader."

That command will lock your bootloader again. However, locking and unlocking will wipe your device.
Upon receiving your unlock code from Motorola, your warranty is void; regardless if you unlock it or not. The sheer act of asking for and receiving the code voids your warranty.
Of course, if there is a true hardware issue that is not caused by software tinkering, you can still use that piece of the warranty.

but I think after reflashing stock, boot logo will be return to normal.
I tried that command and relock the bootloader several times as i didnt got the same battery backup as stock... So my question is after relocking and flahing stock rom... Do i get the OTA? and will it get flashed sucessfully?

Yes you will be able to get over the air updates after relocking bootloader if necessary system apps and files are not modified.
If you are not able to get ota you could also flash stick firmware images.
Thanks man... I flashed the whole stock rom from xda here only...
Even though I've run the commands to re-lock, going into the fastboot (bootloader) mode shows it's unlocked.
Anyone figure out a way to actually re-lock it?

No, once it's unlocked, the counter will always show an unlocked bootloader. Best you can do is hide the opening unlocked bootloader screen.
In the 1st Moto G i have sucessfully relocked the bootloader.
You can use the command 'fastboot oem lock begin', then flash all files from fastboot firmware changing the logo file to logo-mod.bin (File that have removed the unlocked warning image, because flashing custom logo.bin doesn't check crc or hash when relocking the bootloader), then finish with 'fastboot oem lock' command.
Example:
fastboot oem lock begin
fastboot flash partition gpt.bin
- - - rest of commands
fastboot erase cache
fastboot erase userdata
fastboot erase customize
fastboot erase clogo
fastboot oem lock
I don't have tested because i don't have unlocked my g3 bootloader yet.
Just try

Been there, done that, got the T-Shirt, doesn't stop the banner from saying the bootloader is unlocked.

Have you flashed moded logo.bin?
I still don't understand the point of all this... why are people trying to go through all the work of relocking the bootloader?!?! There is ZERO benefit to it... your warranty is still void (you don't even have to unlock, just agree to the terms and get the unlock token), it doesn't enhance resale value, it doesn't change the performance, so why all the effort to try to do it?!?!

to get the new official OTA... if bootloader is locked and have stock rom we are able to get the OTA and can flash successfully with it... though it shows bootloader unlocked warning.

Hmm... Are you sure? If you are unlocked but otherwise pure stock, you should still get OTAs, if your not then they are most likely blocked server-side not client-side. In other words just accepting the T&C of a Motorola bootloader unlock could not only void your warranty, but also blacklist your IMEI from OTAs as well.
I could be wrong, but I think your "barking up the wrong tree" here... I can tell you for sure that Huawei does it this way since Lollipop, if you unlock the bootloader your IMEI is blacklisted server-side... They are very straightforward about it.

not at all... already flashed official firmware 3 times after experiencing the less battery backup on custom roms. in this 3 times i flashed the modified bootlogo so didnt got the warning of bootloader unstlocked and not able to get the OTA but then again i flashed the official firmware 4th time and without that modified bootlogo in hope to get the latest OTA build no. LPI23.72-65 and it worked i got that update next day... and still its show bootloader unlocked warning... so that warnling doesn't affect the OTA is you have everything stock with locked bootloder.
Can anyone post a modified logo without the unlocked warning? My bootlock is relocked but i wanna get rid of this message. Thanks!
Just to clear up any confusion. There is no need to relock the bootloader. In fact it seems like a waste of time to me...

After I unlock my device bootloader, am I still eligible to receive software upgrades from Motorola?
Unlocking your bootloader does not affect your eligibility to receive over-the-air (OTA) upgrades from Motorola. Upgrade packages to new versions of Android will be pushed to all eligible devices, regardless of their bootloader locking status.

So I have not really been on here since last spring when the g5 was rooted, and once more in the early winter, to do Prime's upgrade to the h83020a.
When I did that upgrade, the 20a, I was just trying to bring the device back to a semi stock state, with locked bootloader, and no root.
It took away root, but the bootloader is still unlocked.
If I just wanted to relock the bootloader, what would I have to do if I am on 20a, no root? In the past I would just dive into the dev section, but I do not have a urge to become an 'expert' on the device, if I am giving it back to Tmob this week.
Can anyone point me to the thread, that would help me with the process of relocking the bootloader, without pooching the phone?
Thanks in advance

If you're running stock, unrooted Ron and haven't made any system changes, all you need to do is use ADB to boot to Fastboot mode:
Code:
ADB reboot bootloader
Once in Fastboot mode type:
Code:
Fastboot OEM lock
Then you will have a locked bootloader again. Just make sure you're running 100% stock first, because if not and you relock the bootloader it could brick it.

Thanks, man. 'Prime said the same thing. I had TWRP before 20a, so just to be sure, I'm going to reflash with LGUP, and than do the adb as he suggested, also.
Hi all !!!
As soon as I received my ZS551KL, I unlocked bootloader, installed TWRP and rooted it.
I cannot update to Android 8 because my bootloader is unlocked, but I cannot found how to relock it for updating. I have tried fastboot oem lock and fastboot oem relock in fastboot mode without success.
Do you know how to do it?
Thank you so much :good:
You can flash raffyvito's modified Oreo zip, that way you get the stock recovery from which you flash the official Asus zip with the firmware updates, then you flash TWRP again and you're golden. You should check out his thread.
Hi guys. Do we have any news on how to relock the bootloader? Also can someone of you share the stock oreo recovery?
