As the topic says, what does the unlocking of the bootloader do and why do you have to do it? Also does unlocking the bootloader void the warranty?

And yes, unlocking the bootloader voids your warranty. But on Nexus is really easy to relock it with fastboot oem lock command.

Personally, this confuses me more than before. I understand the concept of a bootloader, but not that a customer rom cannot be loaded without it being unlocked. I'm using an ATT Galaxy S5, which as I understand cannot be unlocked. However, my device is rooted and has a custom rom loaded (Dynamic KAT 4.0 NI2 build).
So what exactly does unlocking the bootloading gain over simply rooting and loading a custom rom such as I have done?
Thanks!
Edit: Crap, just realized this is a really old thread. I'll search further...
Different devices have different methods of rooting, the nexus s is one that you need to unlock the bootloader first, then you can root and/or flash a custom ROM, recovery, kernel, etc
Yes some phone don't need you to unlock bootloader and yes some bootloaders can't be unlocked so you're question is device specific in the sense that every device is different
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

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?!?!

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.

I've searched for a answer all over XDA, but it seems like there's just no way to fix my issue, or is there a solution?
The problem that I've currently got is that my bootloader is locked (I used the OnePlus-Windows-Fix-One.zip to get back to stock, but I didn't know it would re-lock my bootloader). And because I of course didn't reset the tampered bit to False I'm now currently stuck with Tampered = True and Unlocked = False. I've tried all kinds of methods to boot a custom recovery, but I later on found out the exploit for this has been removed in the update after CM11 25R.
I've seen people talking about rooting their device without a unlocked bootloader or a custom recovery (Kingroot). Would this be possible with Cyanogen OS 13 on the OnePlus One?
Thank you very much for all the answers in advance!
Edit: The way I would resolve this issue after rooting is installing a custom recovery and flash the tampered bit reset zip.
Is there a way to just root your phone without unlocking your boot loader? I just want to simply root and install some apps that require root but that is it.
Thanks...

I'm pretty sure that you need to unlock your bootloader first.
Not sure if you can unlock - root - relock ??
I think this is not possible yet without unlocking the bootloader.

Once you unlock and relock your bootloader, its status will be relocked, so your warranty is void anyways.
So I have to unlock the boot loader first. Dam I assume that is on the difficult side of things as well...

If you want the status to show "locked" and not relocked to get your warranty back, you can use the downgrade package from nougat to marshmallow and flash stock B131.
I managed to relock my bootloader using this method : my fastboot screen says "locked" (and not "relocked")

Wait for kingroot method. No need to unlocking bootloader to root, people do it because its only one way to have root on honor 8 now - by flashing supersu in twrp, and twrp/modified recovery you can flash only if you unlocked your bootloader first.

I confirm.
I am considering relocking the bootloader for my HTC U12+. I unlocked it a long time ago (out of habit I guess). So my phone is completely running stock without any modifications. I want to relock the phone to get widewine back to L1, so I'll get Netflix updates and such.
A few questions about relocking that I couldn't find an answer to.
1. When I relock the bootloader will it do a factory reset to the phone? I'm asking because unlocking did.
2. If later on I decide to unlock the relocked bootloader again, do I have to get another unlock-code from HTC? Or is unlocking a relocked bootloader a simpler procedure?
So I decided to do the relocking. During the relocking procedure I was being told on the screen that the phone will be wiped if I continue. It remains to be seen how I'll unlock it later on if I want to.

2. You have to to go through the HTCDev website procedure (not sure if you can reuse the previous Unlock_code.bin file).
is it possible to get "locked bootloader" instead of "relocked bootloader" and get rid of system status modified?
