Unlocked bootloader - Remove warning - G4 Q&A, Help & Troubleshooting

Hi
I unlocked the bootloader when I first got the phone. I am going to sell it soon to make way for the Nexus 6P.
Is it possible to remove the bootloader unlocked warning when the phone first boots up?
Thanks for any advice.

i guess nope

If your selling and want it back to original the only way I know is fastboot oem lock

If you're going to sell a device that is bootloader unlocked, you have to tell this the person you're selling it to, since it's no longer covered by the warranty. Don't tell me it is. Currently only the European model is unlockable and here in europe laws and regulations are unified among countries within the EU. I hope you do. Otherwise it's just fraudulent, but that's none of my business.

No, that command does not work on bootloader unlockable devices unless it's a Nexus/OPO/OPT/Huawei/Oppo and some older Motorola devices. etc.

[Q] Possible root without unlocking?

I've just bought my Galaxy Nexus for two days to replace my dead Nexus One.
The UI of ICS is so great but I miss the function from DEVs, like vibrate when the call made.
I have rooted my Nexus One without unlocking the bootloader and I would love to root my Galaxy Nexus without unlocking too.
Is there any DEV going to work on this?
I don't believe anybody is working on this since BL unlock is so simple, and there aren't really any disadvantages (that I know of). In order for root to occur without BL unlock, there would have to be an exploit found in the stock image. Is there a particular reason you don't want to unlock it? You have only had the phone two days, so I imagine your data loss won't be that big of an issue.

And rooting doesn't? After all, it does allow for modification/deletion of system files. In any case, you can re-lock it just as easily.

Accidentally thanked you haha - missed the quote button.
You can lock it if you have to send it in or return it, you know. The lock command is just as simple as the unlock!

Rooting doesn't make the splash screen change (the lock under "Google"), so it can be easily unroot by deleting related files in the system and make it look like stock.
Are you sure a unlocked devices can lock again? Nexus One can't do this.

Yes, "fastboot oem lock" will re-lock the bootloader and make the padlock go away. Here is the write-up by droid-life (I can't view it at work, so I hope it has the right info!)

Mine one is the GSM one, I have searched on Googles, there is no GSM version re-lock tutorial there, so I doubt GSM version cannot re-lock.
And I don't have the stock image.

I thought the GSM factory image was pretty widely available?

I am fairly certain people with the GSM variant have re-locked their phones, but I would check the Nexus android development section (GSM) for proof.
I've tested relocking and can confirm it works fine

I feel like this is a myth. You're not using an exploit, or anything like that, you're using a manufacturer provided tool to unlock the bootloader. Taken from android.com:
On Nexus One, Nexus S, Nexus S 4G, Xoom, and Galaxy Nexus, the bootloader is locked by default. With the device in fastboot mode, the bootloader is unlocked with
$ fastboot oem unlock
The procedure must be confirmed on-screen, and deletes the user data for privacy reasons. It only needs to be run once.
On Nexus One, the operation voids the warranty and is irreversible.
On Nexus S, Nexus S 4G, Xoom, and Galaxy Nexus, the bootloader can be locked back with
$ fastboot oem lock

I would love a way to root without unlocking the bootloader -- coming from the Nexus One, which I easily rooted without ever touching the bootloader -- it didn't occur to me that rooting would require unlocking the bootloader. Of course, I wish now that I'd unlocked the bootloader right when I took the phone out of the box, which is, I see now, what everyone recommends. But I've more data on the phone than I want to deal with losing right now.
So if anyone following this thread turns up a way to root without unlocking the bootloader, please let us know!
You won't see this feature arrive until manufacturers start selling ICS phones with locked bootloaders (I'm looking at you HTC, LG, etc). Devs will then try to punch a hole through the OS instead of using simple fastboot commands, as the bootloader will be locked down.
I don't understand why you would wait though, just fastboot oem unlock, root, then fastboot oem lock. The only way your warranty is going to be voided is if you have a rooted rom, that padlock means nothing on the Galaxy Nexus. IF THEY SEE SUPERUSER, THEY KNOW YOU ROOTED. They don't give a **** about the splash screen

[Q] What's the benefit of relocking the bootloader?

Curious.....and I didn't see a thread about why some folks do so
none. its the same thing, just have it relocked when u send it in for warranty purposes + on stock
Like zephiK said: none. There is absolutely zero benefit to relocking the bootloader. On the contrary, there are many disadvantages:
if you ever have to unlock again, it will wipe your data
you cannot use most fastboot commands, which means that, unless you have root, you cannot flash radios, ROMs, backup your data, etc...
People relock their bootloader because, in my opinion, they are not very knowledgeable about how Nexus devices work, and have it in their head that, to be fully stock and receive/install OTA updates, you need to have a locked bootloader. Certainly not the case.
There was a guy on here who wanted to return his phone back to stock for warranty. His USB was broken. He could return everything to stock through the phone, except for locking the bootloader. If it was already locked, the problem wouldn't be there...
Not a good enough reason for me, but it could be a factor in your decision...

I still don't know if I believe that Samsung will not honor the warranty because the bootloader is unlocked, particularly on a device with a re-lockable bootloader.
As we know, HTC honored the warranty on the Nexus One, even though with an unlocked bootloader.

it's not so much the OEM, its more of the carrier.
vzw will not honor anything if the bootloader is unlocked.
Like I said, it's not a factor for me. I unlocked with about 10 minutes of my first full charge, and don't see any value switching back. Everyone is different though, so I thought I would just share this detail, no matter how trivial...

Not really. You can flash a stock ROM and via ROM Manager - you just can't lock the bootloader...

You bought a Verizon variant. With Verizon models you can't check "oem unlock" so you can't unlock the bootloader. You are stuck with a locked phone. No root.

Carrier locked phone from ebay What carrier? how to unlock?

edit: seems it is EE UK its locked to , got a popup
Unlock carrier
Hi, you can unlock the carrier by reflashing the OS on the phone. PM me if you have further inquiries.

Really? Just got in contact with the seller and he will unlock it with EE.
But can you flash the pixel on locked bootloader? and it will get rid of carrier lock as well?
.
Yes, it gets rid of the carrier lock and it changes to the International version. Though there is another way you can unlock it and that doesn't require flashing the phone.

That requires paying for an unlock code for the phone, they are usually between 5 to 8 US$.

I would not trust this muhammad guy as he is using "sim unlock" language interchangably with device lock. If it is a verizon locked device with OEM unlock greyed out, it is my understanding there is no way to ever fix that. Verizon is the one that implemented that lock, they will not help you unlock it, even if you tell them you are a developer. They tell you to get a google pixel phone directly from google for developer purposes.
having your phone "sim-unlocked" is very different from the device being unlocked.
v12xke said:
If you have already 100% WIPED your phone, skipped through setup and gone straight to dev settings with an active Wi-FI signal and get a greyed out OEM unlock , you will likely never succeed because you inadvertently purchased a bootloader locked phone. SIM unlocked definitely does not equal BL unlockable.

But if it is a Verizon version that was able to be OEM Unlocksd and flashed to LOS like I have done, it is now unlocked? Somehow I was lucky in being able to enable OEM unlock on mine.

Question i heard something about bootloader un/relocking

is it true that relocking a unlocked bootloader erases everything, but you can re-unlock it ever again on xiaomi devices?

Hi,
I am new Poco F3 owner,
I got the Amazon black Friday deal £50 off,
my variant has 8gb of rom & 256gb of ram, all this for £269.00p,
what an Amazing price and also comes with 2 years warranty here in the UK.
I have been a LG users for many years, using the (G2, G4, and for now a G7) .
I have installed many custom roms on these devices over the last 8 years.
Unlocking/locking there bootloader have been relatively straight forward.
I asking the same question that I am sure has been asked many times before,
once my 7 days are up and i have unlocked my bootloader and i then lock it again,
but then further down the line i decide to unlock it again,
do i have to wait another 7 pointless days.
I'm loving the new poco F3, apart from the firmware is a bit restrictive,
hence why I'm unlocking the bootloader.
What a great community the F3 has , long may it continue,
regards,
Johnr64

No, you only have to wait the first time.
This waiting time is not so pointless as it seems however. It is there to discourage a.o. the many traders flashing (often fake) 'global' roms on Chinese phones and selling them as genuine global models for extra profit. So in the end it's only for your protection, because flashing roms invalidates warranty.
so just to clarify there is no limit on unlocking and relocking this phone right?

xiaomi unlock tool its infinite dont worry, but be extreme cautious when you are locking your bootloader make sure your are in your right stock rom and dont forget to unlock again when you are going to flash custom roms and recovery
To lock the bootloader you can simply use "fastboot oem lock" in fastboot mode. Note that doing so will (obviously) factory reset your phone.

ok, another question:
in the event where i lose my phone an unlocked bootloader can bypass any password protection if they have the knowledge right?
is there any way to protect the phone from this?

If you mean screen lock, yes they can bypass it. But they cannot get into your banking apps or others which have their own passwords.
If you are really keen on it, just lock the bootloader.
