Is there any way to get an LG G2 (running the latest version of stock software, Lollipop 5.0.2) in fastboot mode? None of the methods listed anywhere online work for me. I'm getting the feeling that it's not an option on this device, but I've heard no definitive confirmation of that.

Here's what I've tried and has not helped:

• Turning the device off, holding down power and volume down buttons, releasing them when the LG logo displays, and holding them down again to power up. This brings the phone into Factory data reset mode, in which the only option is to Erase all user data & restore default settings.
• Turning the device off, holding the volume up, and plugging a connected USB cable into the phone. This brings the phone into Download Mode.
• adb reboot fastboot. This reboots the phone normally.
• adb reboot bootloader. This also reboots the phone normally.

To be clear, I mean that fastboot devices lists nothing when I do any of the above methods. But adb is working.

Download mode may appear prior to fastboot mode.

1. Boot down the phone
2. Keep holding down Volume Up button.
3. Put a USB cable that is connected to a PC in to phone.
4. Continue holding Volume Up button throughout download mode until fastbood mode appears and you can release the Volume Up button.

Per this thread, the fastboot is entered in when boot partitions get corrupted. For obvious reasons, I'm not overly thrilled about testing this theory by corrupting my boot partitions :)

SarpSTA's answer is correct, but if you're on Windows you may need to install qualcomm drivers for some versions of the LG G2. I had to do this for the ls980 as per this post:

Start by installing qualcomm drivers on your windows machine to better detect which mode your phone is in right now:

Unzip into a regular folder onto desktop. Plug in device and go to device manager. Find device that is phone, right click and update driver. Choose option to provide your own driver and point to the location of the entire folder of qualcomm drivers on the desktop. When done, note how the device is described in device manger. It should be more specific now. It sounds like you may be in a QDLoader 9008 mode since no partitions are showing up for you.

Even though it said my drivers appear to be up to date, it would not boot into fastboot mode until after attempting to update from this Qualcomm_Drivers package. Prior to that it would mount a bunch of drives.

1. Power off your LG device;
2. Connect your USB cable to your computer, but not your phone
3. Press and hold the Power and Volume Up keys simultaneously. Hold for about 5 to 8 seconds. Now connect the other end of the USB cable to your phone;
4. Done!If it worked, you're welcome.

Hi I had the same problem on my LG G2 mini.This command worked for me:dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/lafBy doing so, the phone can't enter Download mode and enters Fastboot mode instead.Use with caution though, I don't know what this really does to the device!

I am having issues( i am a 'novice' when it comes to unlocking a30 android bootloader with a PC...) with booting into bootloader/fastboot mode on my stock rom--android 7--Alcatel a30(non rooted 5049z?)smartphone;i have tried the power button/volume button sequence method...no luck there,and have tried the adb method using:adb reboot bootloader/fastboot..again no luck!!!

I would like to know if any forum members know how i may unlock my a30 bootloader without(if possible?)rebooting to the aforementioned bootloader modes or is this phones bootloader unlockable without removing FRP(Factory Reset Protection)????

Thanks in advance for any helpful replies!

You have several questions,
To answer the last one, yes... and no

On device's that use MTK CPU's, you don't need to unlock the bootloader as the bootloader on MTK's is not Fastboot . .MTK is famous for being UNBRICKABLE !!! Meaning you don't need to unlock the Fastboot at all...

The reason your having trouble is because it isn't necessary to unlock the bootloader ...

I'm not sure why Andy### thinks that being a MediaTek would make it harder, because that's just not the case... it usually means easier...

Let me explain why the Fastboot is useless..

How To Put Device Into Fastboot Mode Windows 10

On MediTek Device's, you dont flash new images via Fastboot because there is size limitations to each image, if you tried to flash a massive 3 GB system, it wouldn't allow you to, because of maximum flash size in Fastboot.... Instead MediaTek uses a Pre-Boot that is prior to the bootloader, it doesn't even have a GUI... This is called the Preloader on MTK Devices, and you do all your flashing using the Preloader... Usually you use a tool called SP Flash Tool for doing flashes....

Unlocking your bootloader isn't necessary, and disabling FRP is not going to make any changes to your bootloader unlocking... You flash a recovery image via the Preloader in SP Flash Tool, and then wipe the partition called FRP, and factory reset... it isn't like other Android ( HTC for example ) Htc devices need to be unlocked in order to install custom recoveries etc... this is not even a problem with MTK Device's because the Preloader gives you factory level flashing abilities.
