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.

Hi all....
2 quick questions....
My Nexus LTE is rooted
when I try to boot into recovery......either with ROM Manager or fastboot...I get the Android with the red triangle.....is it because I have my bootloader locked???
Even though I unlocked it to root...I locked it just in case I have to bring it back to Verizon...
also......If I do have to unlock it to get to recovery.........after I unlock it...would I lose all my data and apps?
1. If you've not unlocked it yet then unlocking it will delete everything
2. You need to unlock it and then flash ClockworkMod to be able to flash a new ROM
I'm about to do this also.
Unlock, root.
I think what the OP is asking is once you unlock and root... can you relock the bootloader without messing up root?
Also when you unlock and it wipes your phone, does it erase everything I've copied over to the internal SD card? I have like 10gb's of music, files, pics, etc.
I think the answer to the above is YES. But just want to make sure. That would really suck as I normally wipe my phone often when crackflashing. Sometimes I'll flash a rom but find out mid-day that it sucks and it'll require a wipe and reload an older version.
Anyway, rooting seems easy enough. Push some files. I'm just curious about how the internal SD card plays its role in all this... as I've always had an SD Card.

I am no expert - but I am pretty sure you are correct.
1. You re-locked your bootloader. So - no custom recovery.
2. Unlocking your bootloader is going to wipe everything. Including your "sd card partition" (whatever you want to call it). So if you have pictures or other important files you need - transfer them before you unlock your bootloader.
3. I would just leave it unlocked. If you need to lock it for warranty issues it is very easy to re-lock. Right? Isn't it something like...
Code:
reboot into bootloader
enter the fastboot command
fastboot oem lock
done
hope that helps. maybe someone will chime in.
So unlocking the bootloader will Kill your sd card files. What about normal wipes from CWM?
I rooted...(no custom rom...leaving it stock)...then relocked my bootloader.....
I then installed all the apps I wanted........
I also was able to get into CWR and make a backup...
now if I try to go into CWR I get the android with the red triangle
why? Is it because I locked the bootloaded? Is that why I get the red trianlge? because bootloader is locked? I can't even get into stock recovery and if it is...if I unlock the bootloader...It will wipe data..and I dont feel like doing that right now.....unless there is another way to get the red triangle fixed
EDIT::::::::::::::::::::: I went to my Rom Manger app...and I reinstalled CWR...and lo and behold.....I was able to boot into Recovery with no problem.....even with my bootloader locked.......
I want custom rom, root and exposed,
But there is the warning of the unlocked bootloader on every boot.
What is the most I can get without this warning?
Thanks a lot.
Nothing wrong.. Tbh I really like that warning since you can easily navigate to recovery, Fastboot etc. Just ignore that warning.

DON'T relock the bootloader as long as your system is modified in any way (custom rom, root ...).
Don't care about the warning, without it you can get absolutely nothing, but using the unrooted stock firmware.
This warning is shown on every thread describing how to unlock the bootloader - if you lock the bootloader with anything that isn't the stock ROM/recovery, then you will brick your device
I personally, have never had any problems with the adb command to lock and unlock the bootloader. The bootloader actually operates independently of the software running. However, why would you want to relock the bootloader, particularly if you intend to flash other ROMs.

I don't like the idea that everyone can wipe my device. I have little brothers and they can do that by accident...

That doesn't depend on a locked bootloader. You CAN'T protect android phones from beeing wiped.

Of course, but from this warning that can happen by accident...
Hello,
I just Unlocked the bootloader of my Samsung A50.
Now I want to undo the bootloader unlock, I mean I want to lock the bootloader as previous.
Is there any way to do this?
Best regards,
Habib.

Locking bootloader won't be any useful as with unlocking knox is tripped which is a hardware fuse.
Only way to properly lock and restore knox is to change the motherboard.
Bootloader Lock
I don't know if this makes sense or something
I have Galaxy A50 A505F/FD and I recently unlocked it's OEM. I don't know if OEM is the same as bootloader. So I wanted to root the phone but I was unsuccessful and I always had that warning that comes up when you are starting the phone that prompts you that the bootloder is unlocked so it is not protected by Knox. All i did is pass through the unlocking options and locking the bootloader came up again and i successfully locked it again. It is now functioning perfectly. No problems. Maybe that's what you need
Please bare in mind that all your data will be erased so it is better you back up first
-back up all your data
-shut down the phone
-hold volume up and down at the same time
-plug-in your cable connected to pc
when the blue-ish screen comes up, release the buttons and you can also remove the cable
-select bootloder unlock option by long pressing volume up button
-select Lock bootloader
-phone will erase all your data
you are set to go
Thank me later

who you might be is not known, what is known about you is that you m8 are an absoulte legend thank you fr
I have a galaxy A50 and recently rooted it and installed twrp recovery and then again flashed the stock image.Now when I boot the phone it shows that ugly bootloader warning.Can I lock the bootloader now?
And also
Will I receive updates?, as the phone status is official.
Im not sure but i think you lost OTA updates even after relocking the bootloader since your knox status is tripped but thats not a big issue since you can still use odin to update your phone.
to remove the bootloader warning you have 2 options:
1- Relock the bootloader since you have stock official rom. To do that you need to turn off the phone, hold V+ and V- and connect the usb cable to your pc, the phone will enter a "special" download mode, long press V+ to relock your bootloader, the phone will factory reset with locked bootloader .
2- Use this method to just remove the warning and keep your phone bootloader unlocked with official or rooted/modded firmware.
