So basically, I have a Verizon note 4 with permanent root. I bought it second hand and it came with permanent root, but the problem is that I have no idea if it has an unlocked bootloader or not . It doesn't have any custom recovery on it aswell. But then it gets me to question how the heck did it get a Permanent ROOT without getting an unlocked bootloader. Oh and i also don't get shown a verizon logo when i reboot my device, only a samsung logo. And i live in South Asia btw, and can run a local
sim with 3g on it no problem as well....
Also worth mentioning is that on "About Device" in "Settings", it says SM-910F...but when i go to fastboot mode, it says SM-910V, and when i connect it to computer, it also says verizon model. Anyways, the real problem is finding out if my phone has bootloader or not. (READ BELOW ASWELL)
Any suggestions plez
PS: I tried to put a code in the dialer, something like *#*#7432XXXX*#*# (tried a lot of diff. codes in dialers aswell). PLUS, I also tried finding if i had an unlocked bootloader from adb and fast boot where u put this command in; "fastboot oem device-info" something like that, but I cant get "fastboot devices" to work (it doesn't give any result even with proper usb drivers and while in fastboot menu from phone) :crying: plez halp me....

Put it into download mode and see if it says, mode: Developer. If it does your bootloader is unlocked

Well it doesn't say so ... sadly.
Anyways, I'm still wondering how the heck did someone install permanent root without unlocking this Verizon??? Like you have to do temporary root and then you unlock bootloader, and then you do perm root... how does one bypass that?
Hi, I have a LG G4 H815 on Lollipop and I want to unlock it's bootloader to root it and flash an update and do other stuff. I want to try to unlock the bootloader the official way but whenever I go into the developer options and press the 'Enable OEM Unlock', it gives me a warning and I tap Ok but the slider still stays at the off position and it stays disabled
I really want to flash some stuff on it because some of the stock LG stuff is pretty crappy. Thanks in advance!
Try to soft reset your device and try after that

I don't have a slider. It's just a tick box. Try updating to the latest version first or reset your phone completely. All your files are wiped anyway when unlocking the bootloader so you have nothing to lose in trying these.

I tried updating my phone to Marshmallow using the LG Flash tool with a kdz but the tool was having its own problems. It kept saying that it couldn't connect to server. I tried a lot of other methods to upgrade to Marshmallow but they didn't work. Do the flash tools need the bootloader to be unlocked too?

Without root or an unlocked bootloader, you can only use official root tools. I don't think your software version matters too much. Just do the full factory reset. There's no reason not to try doing this as bootloader unlocking does a factory reset itself.
I have also tried everything on my lg g4 on marshmallow...but can't turn on the oem unlock tick...
Any solutions
I tried factory reset too but still, not switching :'(

I got the same issue as yours here...and cannot even flash some Stock Rom on this "H815" model.....is your phone a refurbished model from Aliexpress? (as I suspect something here)
Dear all
After spending 3 days searching on the net, I found the way :
"Just purchased a LG G4 (H815). I'm in the process of unlocking the bootloader, and have been following LG's official instructions. However, I am having trouble performing step 8 of this guide:
"Enable OEM unlock on your phone. Activating the "Enable OEM unlock" is necessary for the bootloader unlock. To enable OEM unlock, go to Settings >> Developer options and check Enable OEM unlock."
Going into developer options and tapping on "Enable OEM unlock" returns the pop up message "WARNING: Device protection features will not work on this device while this setting is turned on. CANCEL ENABLE". After checking ENABLE, the pop up goes away, and I can see the checkmark box is checked for less than a second, and then it goes back to being unchecked on its own. Can anyone explain this?
Also, if instead of tapping CANCEL or ENABLE on the pop up, I click off of the pop up, the pop up goes away and the box will stay check marked until I interact with something else. Entering adb reboot bootloader from here though still does nothing sadly.
UPDATE: I had to download LG Bridge, connect my phone and use LG Bridge to search for a software update (H81520H) that my LG G4's update center was not finding for some reason. After the update, I had an update android security patch level, and could enable my OEM Unlock!"
Hi,
Thanks for the reply.
LG Bridge doesn't solve the thing for me, it says "Your phone is up to date" ... I installed and removed LG Bridge a few times and even tried to update it. And even tried the "Update error recovery" (blue text on the bottom right of the window), still with no success.
Still no access to Fastboot for me, even if Adb sees in device when prompting the command "adb devices".
This "H815 20o" software version I got (from stock rom, refurbished phone, with this insane locked bootloader) is driving me nuts for 3 days now...
Up,
If anybody ever got the same issue, any help is very welcome!

NEVER lock a phone with custom firmware installed. This usually leads to bootloops.

What are the steps you took before relocking the bootloader?
In my experience, relocking the bootloader should be the last thing you do, after you've got a working/bootable stock ROM.

So, after i installed the latest stock rom, the device worked normally, but after waiting a while for the oem lock option appear in development options, it din´t show up. so i just gave up and installed lineage 19.1 but if i can i want to lock the bootloader again.
Raphael, I think you might have quoted my post twice, but didn't add an actual answer. Or maybe I'm super blind and I can't see it.

So, the OEM lock/unlock thing comes with a pretty big caveat, and you need to be aware of it: loss of data.
Every time you lock or unlock your bootloader, a wipe data is triggered.
Now, for as far as I know, to lock the bootloader, you need two things:
1. Stock ROM. Don't do this on a custom ROM!
2. following command, in Terminal/Cmd Prompt
fastboot oem lock
Of course, you need to be in fastboot mode, so if you're not, and if you're booted and connected via USB (USB debugging needs to be ON and RSA fingerprinting accepted), do:
adb devices
It should display your device here. This is just to make sure ADB is working properly.
adb reboot bootloader
At this point, the phone should reboot into bootloader, so now you can do the lock command
fastboot oem lock
Data should be erased and, in case it doesn't automatically boot up, you can reboot the phone.
Don't worry about the OEM unlocking option in Developer Options. You just make sure the stock ROM is functional before attempting to relock the bootloader.

I tried that, and it din´t work, this method is the same that was in a help thread in xda forum of my device, this command works fine in my nexus 6, but on my moto one action it does not, i unlocked my bootloader via the normal method using motorola´s website, not using another method.

no, i run the command and it asks for changing the oem lock setting in developer options, i reboot the phone and run through the setup process. Then when i enable developer options and check the oem lock option, it is greyed out.
Is it greyed out in the on or off position? Can you attach a screenshot? I don't remember the operations sequence... But I think the option was automatically switched back to the original position (off) when you lock the bootloader. I could be wrong though. So...when you run the "fastboot oem lock" command, it asks you to....what?
Set the option to on or off? Some screenshots from both the PC, with the message, and the developer options might help to clarify this.

it is greyed in the on position, i can´t add a screenshot because i am in lineage 19.1 with root and the option shows up,when i run the command in cmd, it says to me to check the oem lock option in developer options

A screenshot would be really useful. But don't worry about it. When you're back to stock rom and ready to lock your bootloader, we can resume this then. I think either we're missing something, or it's everything ok, and you just need to switch that option off. Though, I remember I didn't have to do it manually. But I could be wrong though.
So, don't worry. Enjoy LineageOS and we can resume this when you're back to stock ROM and ready to lock.

so after running the fastboot oem lock command, it asked this in the cmd
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem lock
...
(bootloader) Check 'Allow OEM Unlock' in Android Settings > Developer
(bootloader) Options
OKAY [ 0.080s]
finished. total time: 0.080s
when i rebooted the phone, it showed the screen saying that the bootloader was unlocked. also i had to re run the command because it was going to erase my phone but that din´t happend, after going to developer options the option was still greyed out.
The last 3 days i've tried some roms from here.first i've unlocked the bootloader in developer menu,then from fastboot with the unlock key provided by motorola website,i've tried different rom,didnt like that i cannot use bank apps.so i went for locking.full reset,adb enable,reboot bootloader,full flash stock rom (last one from Motorola),reboot to check,adb enable, reboot bootloader,run command " fastboot oem lock " once ,it asked for confirmation due to data loss,then run command " fastboot oem lock " once more,then reboot to os.everything went ok,device dont show that was unlocked
Hey everyone!
I was updating to the latest Android beta to try to get the Move to iOS app to work. The update seemingly went fine and I was using my phone (on reddit lol) and suddenly it powered off.
Now when it starts I get a black screen that asyas "Fastboot Mode". My phone isn't unlocked so I haven't done anything funky with the firmware.
I'm afraid I've lost everything on the phone
Here's a picture of what the phone shows:

Well, the fact you can boot into fastboot is good news
Before we talk about possible actions:
- what ROM exactly were you coming from ? Was that rooted or with a custom kernel ? Was the device unlocked ?
- what ROM exactly have you been flashing ? By using which method ? Any additional steps you did while/after flashing this ?

You should never install Betas without having the bootloader unlocked. Is OEM unlocking at least enabled in Developer Options (I know you can't get in there right now, but was it enabled before the phone stopped being able to boot to Android)? If OEM unlocking is enabled, even with the bootloader locked now, you can try Official Google Android Flash Tool (OEM Unlocking needs to be toggled on - you may not have to manually unlock the bootloader - the "site" will do that on its own).
If OEM unlocking isn't enabled, there's probably nothing you can do to fix the phone - you'll have to RMA it.
Pretty sure he can sideload an ota if USB debugging was enabled. One user reported they were able to sideload with locked bootloader

You can sideload OTA updateds without USB debugging enabled. It's really the only way forward for op.
