Hey there. I'm new here, and to be honest, I'm new to the world of smart phones. The 4xHD is my first smartphone and I've had it for about a year now. I've noticed that it performs really badly on the 4.1.2 JB so I've decided to root it, unlock the bootloader, flash cwm and get a Cyanogenmod 10.1.3 up and running on it.
Long story short, I've rooted my phone and followed this http://forum.xda-developers.com/showthread.php?t=2245836 thread to unlock the bootloader but it didn't really go as planned. I did the things in the cmd app on the phone, and did the first line of cmd on my lap top (adb reboot bootloader) and when I wanted to do the second line (fastboot oem unlock) the cmd said it was waiting for the device. I waited for 5 minutes and nothing was happening on the device. It was stuck on the LG screen (not the one with flashing lights, just the logo screen). I pulled out the USB and pressed volume down and the power button just in case. Then I pulled out the battery, turned on my phone and went to the 3845#*880# secret menu to check the bootloader status. When I tapped on the bootloader unlock check thing, it said "Unlock".
So, did I just unlock the bootloader? Operation successful? Is there a possibility that I didn't unlock the bootloader in a correct way so it will brick my device when I try to flash cwm and Cyanogen?
I'm really sorry if this thread is in a wrong section or something. I searched on the xda but couldn't find the answer to my question.
Thanks in advance
EDIT: I'd also like to mention that in no part have I encountered the screen which said "you're about to unlock your bootloader, warranty voiding, blah blah blah, are you sure you want to proceed"
There is a way to lock our moto g back after unlock with motorola own procedure ?
I search here but nothing till now, only a procedure to mask the startup screen with message about unlocked device (white screen with red text) with anothers screen with a static earth image andM from motorola.
Then you haven't searched well... Lock Bootloader http://forum.xda-developers.com/showthread.php?t=2700502
Own lock begin and OEM lock doesn't work
Are you re-flashing the stock ROM in between running the command oem lock begin and oem lock?
I have an xt1032 and was able to lock and unlock.
You should note that even if you re-lock the bootloader, I think Motorola will still know you unlocked the bootloader. Apparently, unlocking the bootloader will blow an e-fuse which cannot be "unblown".
Thanks for your response
So, I've unlocked the bootloader, flashed TWRP. It says it's successful. But when I try to boot to the recovery, I get a warning that says "Your device software can't be checked for corruption. Please lock the bootloader." and won't load TWRP after that.
I've checked a bunch of other threads, but can't seem to find a resolution for this. Can anybody help?
Tap the power button twice when the screen appears. (If it's the screen I think it is... American carriers are known to add extra protection)
That just puts me right back at the bootloader. It does say S-On though. Do I need S-Off?
Hey everyone,
I have an LG G5 and I'm trying to hardreset it. I can't turn it on because it always goes into "incompatible module" mode, telling me to change the battery. The power button also doesn't work anymore.
I have however managed to get it into fast boot mode. From there I tried to use
Code:
fastboot erase userdata
but it says that the bootloader is locked. I checked with LG and they said that my particular phone (from Australia) can't officially be unlocked.
Now I'm looking for a way to either unofficially unlock it or to wipe all data with fast boot without having to unlock it. I can't use adb because it somehow doesn't recognize my phone, fastboot does.
Thanks,
Josh
Goodnight all,
I unlocked the OEM bootloader and Rooted my Samsung Galaxy Z Flip 4 using Magisk. It is a European model.
Now each time I start it I get warning messages that the security has changed as a result.
I reset my phone completely and I still have these warning messages on startup.
Is it possible to remove these warning messages because I will most certainly resell the phone???Is there a solution to lock the OEM bootloader again or is it irreversible???
Thank you in advance for your help and good evening to all.
This is by design. An unlocked bootloader should display the ORANGE state on boot to notify the user. This is normal, and no action is needed.
It is not possible to remove these warning messages as this is a result of the bootloader functioning as intended.
You can re-lock your bootloader if you want but make sure you have performed a clean flash with the factory firmware first. You would then follow the same process you used to unlock the bootloader (device off, hold both Volume buttons, plug in USB cable).
It's just a minor inconvenience though and does not affect device operation.
Good evening,
@V0latyle
if I understood your explanation , I download the latest firmware which is installed on my phone with the help of SamFirm or other software.
Then I use Odin in administrator mode and I select the file in the BL box, the file in the AP box, the file in the CP box and especially in the CSC box I put the CSC file (and not Home_CSC) in order to a hard reset of my Samsung Galaxy Z Flip 4 phone. Once the flash is done, the phone reboots to factory state, I click the build number 7 times then I go to developer options and there I could finally lock my OEM development loader again??? Once I've done all of this
,will the bootloader security warning message go away???
Please tell me if I understood correctly please and above all thank you again for your help.

You don't have to do anything with Developer Options or the OEM Unlock toggle. OEM Unlocking only functions as a "safety" to permit you to unlock your bootloader.
If it is already unlocked, simply follow the instructions you used to unlock it after you enabled OEM Unlocking the first time - with the device powered off, use the key combo to boot into Download Mode, then hold Volume Up until you see the device lock warning. When you relock the bootloader, it will wipe data. Once done, no further steps are needed.
If you want to tinker with your device and enjoy the benefits of root, why not leave it unlocked? Sure the bootloader warnning is slightly annoying but again that's by design.
@V0latyle
ah ok, I understand better, I'm doing the reverse step of what I did the very first time I unlocked the OEM bootloader.
I put my phone in download mode by connecting it to my computer and then I hold the volume up key for a long time to lock the OEM bootloader. And if I understood correctly, once this is done, my phone will be factory reset and no more warning message on startup. That's right ???
In fact, I'm asking you all this because I want to sell my phone to switch to the S23 Ultra.
thank you for your help and your feedback

Yes, if the bootloader is locked and the firmware is original OEM, there should be no warning.
@V0latyle I'm testing all this to the letter tomorrow evening and in the process I'll come back for other people that it could help.
thank you for your help and keep you posted
Hello,
I did what you said and problem solved, the warning messages at startup disappeared.
Thank you again for your help @V0latyle
But u know that KNOX is triggered and u loose some of functions anyway even if you relock bootloader ?
