If you plan on selling it, don't bother flashing back to stock. I would think it is more valuable already unlocked.

Not selling. Handing down to someone that has no business having root lol. Or unlocked bootloader blocking apps they use regularly.

Should have mentioned it in the OP.
Download the kdz for your variant
Download LG usb driver
Download lgup
Choose upgrade and flash kdz.
Good luck,

Thanks. When unlocking the bootloader, I recall an adb command. Or fastboot. Something like that. Will I need to reverse that?

What is a bootloader and how do I upgrade one?

Hi guys
I bought the Note 3, I'm trying to put TWRP recovery on. But there is a note saying
Use the 4.3 version of TWRP if you have never upgraded kitkat bootloader. Otherwise make sure you use the 4.4 version. These versions of TWRP have different DTBs and will fail to boot if you do not match your bootloader.​
So, how do I know if I have which bootloader?
[QUOTE So, how do I know if I have which bootloader?[/QUOTE]
Get an app from tge Play store. It's called Info. Here is the link:
https://play.google.com/store/apps/details?id=com.app.info
You will find there what you need. Good luck!

Wrong post
Can you check if I have the correct bootloader installed?
I can not make any phone calls at the moment, I get "com.android.phone as stopped" error. Is something wrong with the bootloader, or kernel or the rom or something else?
Please help me. I can not call or receive any calls, I miss talking to my mom.

relocking bootloader

Tried ome relock code does not work. Anyone got a fix for this on how to lock boot loader back up. Also can this be remain unlocked and rooted and still get android 6 and marshmallow on it or needs to be locked back up as stock has come out final firmware?
no chance brother . only what can do,flash a stockrom over fastboot.
So installing stock Rom should relock boot up? Is boot and root needed with the ofical update and including to use dual sim option ?

I am wondering if currently anyway to unlock the bootloader on this version. If not, is there a way to rollback to an older version and then unlock it?

For starters, you cannot downgrade without an unlocked bootloader. Chicken and the egg :cyclops:
See the thread https://forum.xda-developers.com/droid-razr-m/general/guide-faq-how-to-root-boot-unlock-t2869432
KITKAT 182/183.46.10 FIRMWARE ONLY.

You appear to have the "unlockable" version, so read the thread above.
If not, there is always the "Sunshine" app (ie pay to unlock).
https://forum.xda-developers.com/showpost.php?p=68976652&postcount=284
You mean I can't unlock it.

Also I know you can install Safestrap I'm just having a b*tch of a time finding it and it may be of some use.
