Unlock bootloader LG G4 H815 Marshmallow.
Hi I have tried a lot but in vain.
My phone stuck every time at bootloader.
After installing sdk, adb and fastboot driver I gave the command to boot into bootloader every time it boots into bootloader according to the command. But never accept any command when it is in bootloader mod like fastboot oem device-id or fastboot reboot or any other.
So is there any solution?
I wanna Unlock My bootloader.
You need to enable "OEM Unlock" in developer menu (about > software info > build number (tap 5 times))

Hi.
Recently I was interested in making a root for my device- LG G4 H815L(Israely version). So i started to explore about the difrences, and some guys told that there is a difference in the bootloader. BUT when I got my phone into bootloader the next massage was written:" *Welcome to Fastboot Mode for bootloader unlock:
Quick Guidance
1) Read Device ID : fastboot oem device-id
2) Write Unlock Key : fastboot flash unlock unlock.bin
3) Check bootloader is unlocked : fastboot getwar unlocked"
As you see this is a guidance how to unlock the bootloader. Now Im in some dilemma because of it.
My questions are:
1. Can I unlock the bootloader?
2. What happens if i get to hard/soft break because of it (and what is the sulution if you know)?
+*Do not flash this on TB3-730F. The F model has different chipset and this recovery will softbrick it.
UNLOCK BOOTLOADER
1-Enable "USB debugging" from developer options.
2- Enable "OEM Unlocking" from developer options.
3- Reboot device in Fastboot , either with "adb reboot bootloader" or with VolDown+Power, to enter Recovery and then select "Reboot into bootloader"
4- Unlock the bootloader with "fastboot oem unlock" follow the instructions on the tablet. (Data will be erased)
5-After success unlock.. Reboot to Fastboot andvl issue "fastboot flash recovery ____________"
replace _____with the TWRP 3.1.1 , easy still just drag the TWRP to the CMD and press enter..
++Allow system modification doesnt brick device so its your choice to allow or not

Hi,
I am using my Nextbit Robin Oem Unlock from last 1 year but today i decided to go back to stock with locked Oem.
I flashed the stock rom and locked the Oem at the same time but when i restarted the phone it got stuck at the boot.
So I went ahead with the 'fastboot oem unlock' command, and here's the problem. All flashing command returns FAILED <remote: device is locked...>.
fastboot oem device-info reads: Device tampered: false, Device unlocked: false. So bootloader is locked. At this point I assume that the bootloader is unlocked, but revert back to locked after reboot (the phone automatically rebooted after executing oem unlock command, so can't get around that).
Tried numerous other methods, using different adb files, no dice. Can't even flash TWRP. Tried adb sideload, same. Tried executing fastboot oem unlock with various different parameter, still locked after reboot. I cannot flash anything into locked bootloader.
Google researched it for few hours, same problem happened to other phones from other manufacturers that came returned from warranty replacement with modified motherboard; OR tampered/broken eMMC/NAND flash. But no such case for Nextbit Robin (yet?).
Pretty hopeless right now since I just found out that Nextbit Robin support ended on Aug 1st.
Guess I'm stuck with locked bootloader and no cell signal phone. Unless someone can help. One can always hope.
Anyway, thanks for reading.

If you bootloader is unlocked I think you can give a try to the Nextbit's Unbrick Tool
As you want to go back to stock , I think this is a good idea.
Now if your bootloader isn't unlocked there is unfortunately nothing I can do for you , unless you unlock it .
Edit #1: If your bootloader is locked , go to bootloader mode by pressing volume down + power button for about 20 seconds and try to see the bootloader state with fastboot commands. If it is unlocked , follow the process in the @nextbitKhang's thread .
Yes that's the main issue. Oem is Locked.
Is there any Oem unlock code i can use to unlock from ADB?
I don't think so ,I'm not sure, but I hope you'll find one.
On your Robin go to settings > system > about phone > tap build number until it shows developer options.
Go into developer options which is in settings > system > developer options.
Make sure OEM unlocking is enabled. (for good measure disable then re-enable)
Also make sure usb debugging is enabled. Have the Robin plugged into a computer so you can enable to pop-up on Robin asking for access for the computer.
Once they are both enabled shut down your phone. Turn it back on while pressing vol down+power and plugged into your computer.
In adb run command fastboot oem unlock
please i'm experiencing the same issue not on nextbit but on GIonee.
i have re-activate both OEM unlocking and USB debugging several times but it all void
same error: Remote: OEM unlock is not allowed
please kindly help
So... I have been stuck with a HTC One E9+ for many months with a lock screen that I literally can't unlock, and flashed TWRP but can't be used because of locked bootloader, I had finally discovered a way to get the unlock token. Here's a little bit of story. I tried to run 'fastboot oem get_identifier_token' in bootloader mode, but the phone returned unknown command. I had tried that when everything was normal. I had check the settings in developer options, and there is nothing related to unlocking bootloader inside there. Until recently, I had discovered 'fastboot oem rebootRUU' from other blog post.
All in all, if you couldn't get the bootloader unlock token in bootloader mode, try to get it in RUU mode.
Good luck!
Hi, i tried to run the command "fastboot oem rebootRUU" but no code appeared.
My razer phone, after the OEM unlock, unlocked it using two-party commands, wrote it into the lineage OS system, and then, cheap, used "fast boot flashing lock_critical" FastBoot flashing lock " After locking the mobile phone, it was found that the "Developer Options" had changed to not allow OEM to unlock. Now the mobile phone is restarted indefinitely, using the "fast boot flash unlock" FastBoot flashing unlock_critical " It can't be unlocked. Unable to write to the official firmware, nor can it start properly! Help, gods! Help me!:crying::crying::crying:
