[Q] unlock bootloader logo

I will receive my galaxy nexus few hours later and plan to unlock my phone. Is there a way to hide the unlock logo after I unlock the bootloader or Can I unlock the bootloader, then root the phone and relock the bootloader after to clear the logo but still get the root access. If yes, then how to relock the bootloader?

fastboot oem lock will re-lock the bootloader

But will I still get the root access of my phone after I relock the bootloader and will the unlock logo disappear when boot up after I relock the bootloader?
p.s. It is retail version

why do you need it locked?

I don't like the unlock logo at bootup and the warranty detail only state that I will lost the warranty if I unlock the bootloader, so relock it in case I need warranty, it may cheat them

so then you relock it if you need to. Development for this phone is very young right now so you'll likely be doing alot of flashing. I flash different rom/kernel combinations probably 3-5 times a day with how often things are updating right now. Besides the little unlock symbol is pretty awesome

I know the development is young, that's why I post this. I just need to confirm
1) Is it possible to relock the bootloader in retail version
2) Will the unlock logo disappear after relock
3) Will the phone can still get the root access after relock the bootloader
Thx very much and please reply me if anyone know!!

1) Yes, "fastboot oem lock"
2) Yes
3) Yes, while "fastboot oem lock" does not touch any of your data, "fastboot oem unlock WILL delete all your data. None of these processes can remove root access, the only way to remove it is to reflash the system partition, either by flashing it manually or through an OTA update.

Pixel XL Locked

My non-Verizon Pixel XL is stuck with a locked bootloader, OEM Unlocking Disabled, and is unable to boot to recovery, or the system (thus I cannot enable OEM unlocking). When I try to boot, it has the red message stating that my device is corrupt, then it turns off and does not boot.
How can I fix this?
I has AOSPA installed before this all went down, but I agree I made some dumb moves, and I am hoping someone here can help me out of this hole.

How did you lock your bootloader with AOSPA still installed? You always go back to stock before re-locking your bootloader. That was a pretty big mistake, and I'm not so sure there is a way around this.
If it's a Google Pixel XL, then try booting into fastboot (hold Power+Volume Down), run the "fastboot oem unlock" command, without quotes to unlock the bootloader, and flash a stock image.
Hope it works.

Can you unlock the bootloader from the bootloader screen with ADB command like you said when "allow OEM unlocking" in developer options has not been enabled? I'm sure that I could do that when I had the Nexus 6 but haven't tried it with my Pixel XL.
I think the command now is: fastboot flashing unlock

I don't think you can, it's why I wasn't sure it would work, but still worth an attempt. I used fastboot oem unlock when I unlocked my bootloader, so I guess the old command still works, but yeah, fastboot flashing unlock is the new way of doing it. :good:

I've tried it and none of that works. The device is on its way back to Google since I just got a Google coverage plan replacement. Hopefully, they won't pitch a fit that it's locked up the way it is.

Unlikely. Are they going to attempt a repair, or just outright replace the phone?

I'm not yet adept on the ins and outs of flashing stuff on this phone. Is it actually possible to flash a custom Rom on the Pixel XL while the bootloader is locked? I know it's not something anyone who values their phone would even attempt but with most phones you could never do it anyway. I understand there is a temporary TWRP that you can boot into without actually installing the custom recovery on your phone. Does this make it possible to do what happened with this user?

You have to have to unlock your bootloader to install any custom rom on the pixel.

Hey did you ever solve this? im in a similar prediciment. My phone keeps bootlopping, trying to flash an older ROM but bootloader is locked and none of the fastboot oem unlock commands work.

The bootloader unlock for the Verizon Pixel/Pixel XL is working. Go here to unlock it.

Might be bricked

Ok first let me start off by saying that I'm an idiot and did something really stupid. I was rooted with an unlocked bootloader on Android 8.1 preview was trying to return to stock and stupidly I locked the bootloader before flashing a factory image. Now I'm stuck on the bootloader screen, if I try to boot it flashes the white screen with the Google logo for a split second then starts going into bootloops. When I tried fastboot oem unlock it says "remote oem unlock not allowed". Does anyone know if there is a way to recover my phone or did I make a very expensive mistake?

From what I know across all devices, a very expensive mistake. :/.
For future reference, yet again, for everyone. PLEASE READ. If you want to relock the bootloader, only do so after you actually boot into the new OS.

Reboot into recovery and factory wipe it. That is your only chance, and it's slim.

RMA

Sideload ota through your recovery.

Your device is corrupt. It can't be trusted and will not boot

Hi friends
Please give me suggestion or guide how to solve problem about handset booting after mistakenly handset OEM locked through fastboot
It enter to fastboot mode but not going to recovery mode or restart in system mode
Is there any solution
If yes then please help me

fastboot oem unlock ?

Actually ive unlocked OEM and install twrp recovery and installed freedom os
Then while checking OEM status ive enter command fastboot OEM lock
It ask me I've pressed yes after that the massage is came after restart as your device is corrupt it can't be trusted and will not boot
After that it enter to fastboot but not going to recovery mode or system
While type command in fastboot OEM unlock massege come failed

This happens because your bootloader has been unlocked at one time. There is no going back, even if you use "fastboot oem lock" later.
Edit: Just noticed the part about your device will not boot. You need to find the system image and flash it. I read somewhere today that OnePlus just released the system image for 4.7.4.

Can you unlock again?

@op, IMHO the best possible solution will be to flash stock rom image and stock recovery if required but I think when you flash stock image it will also flash stock recovery.

When you turn off the phone and boot it with VOLUME UP plus POWER, this should send you straight away to Fastboot. Try if you can unlock again, otherwise... bad luck - you'll need a restore session with 1+.

Not to be unrespectful, but you're wrong, it is absolutely possible to relock bootloader without problems.
IMHO, trouble happened because he had a custom rom onboard... and a locked bootloader does exactly its purpose... to not boot insecure firmware!

After looking into it further, I agree with you. That's what I get for having a bootloader-locked Samsung device for two years. I must be getting rusty!
Yes, the bootloader can be re-locked. There may still be a tamper flag as with previous OnePlus devices. But having a locked bootloader with non-OEM software would likely cause the problem he is describing. So, he needs to flash the factory image from bootloader.

I've requested to 1+support for restore remote session
Support send me file link and l2 will assist me in within 2 days

DO NOT RELOCK BOOTLOADER UNLESS U READ UP FIRST!!!!!, its worth just waiting the few seconds after reboot, then to go and try to relock the bootloader

Did you by any chance re-lock the bootloader with a custom recovery and custom ROM flashed?

It's because of custom recovery.
Just flash stock recovery image before locking the bootloader.
This fixed for me.

You unlocked bootloader, flashed rom (custom) and relocked bootloader? Never lock your bootloader on a custom rom! Just enter fastboot again flash twrp (manual/force reboot recovery), copy internal storage to pc then wipe/format everything. Format data. Factory reset then flash latest official rom and reboot

OEM Locked, and Device is corrupt. Unfixable?

So, long story short I recently decided to try and root my oneplus7t I unfortunately made some mistakes and somehow corrupted some files. I read elsewhere in the forum that I could download the stock rom which I did and then use flash-all and that would allow me to go back to the factory settings so I could lock the oem and just go back to normal because I was tired of the headache. Unfortunately, after using flash-all I locked the oem thinking everything should be stock and it would work properly. But it says device is corrupt and trying to unlock the oem says oem unlocking is disabled.
So did I just completely brick my phone? I don't know of anyway to fix it at this point :/.

Can you still boot into bootloader via the hardware keys, whatever that combo is on the 7t?
Boot to bootloader or recovery and factory reset it or so.

I can get to the bootloader but it's Device State -locked and when I tell it to boot into recovery it says the device is corrupt. When I use fastboot to oem unlock it says I cannot, and I can't flash when oem is locked either.

Try
fastboot erase userdata and
Fastboot erase cache
Let me know if that works or not we will move on. Probably won't work since it's bootloader locked
You may have to contact OP and while you're at it, get the MSM tool for us all :good:

It says erase is not allowed in locked state . I think this is probably all she wrote for this one. I think I'm just going to send it back tbh, the whole reason I was trying to root it was because it didn't work with Sprint like they said it would. and I was wondering if I could find a way too make it work with custom software. Thanks for trying

Are you able to flash one of these Fastboot ROMs?

Maybe Sideload can work!

I unfortunately no longer have Twrp installed as I did a flash-all with a stock rom already . If I try and flash recovery it says "flashing is not alllowed in lock state". Sideloading wasn't functional back when I had twrp either as the functionality for it is still in progress. I'll probably try contacting support one more time and see if I can get a T2 who can unbrick it, otherwise I'm just going to send it back. Thanks for the attempts guys!
Edit: As to the flashboot roms I flash-all'ed one of them and that's how I got into this mess :/.

I ended up needing to flash the fastboot 10.0.3 firmware and was able to do a local upgrade to 10.0.4 that way, then flashing a patched boot.img via fastboot

I can't run any flash commands as my oem is locked. I don't suppose there's anyway around that?

How did you flash twrp with it oem locked??That doesnt make sense

I had twrp on it when the oem was unlocked, I was trying to reset the device to stock, so I did a flash-all and then oem locked it. But for some reason the repair was unsuccessful, and now it says my device is corrupted and I forgot to turn on oem unlocking in the settings on my phone after the flash-all before I did the oem-lock.

You should have no issues reflashing the stock images

I cannot flash anything. Because my OEM state is locked.

Boot to Stock Recovery ?
Holding for a long time Volume Down + Power Buttons while booting your phone ?

Volume down plus power button takes me to "Your device is corrupt and will not boot"

Looks like you will need the MSM tool to fix this issue. You'll have to contact OP support and they will remote in your PC, load their software and flash it 100pct back to stock.
Also, disconnect them before they can delete the MSM tool so we can have it here in the community

Press volume up/down and power, reboot to fastboot. Unlock bootloader again. Install update from settings, reboot and install it again. (local install)
Factory reset in setting, reboot fastboot, lock bootloader. Reboot and untick unlock bootloader in developer settings.

Don't know if it's too late but I believe there's a working MSM tool now
