How to Enable fastboot for LG L90 D415

The LG L90 does have fastboot, but it’s hiding "behind" LG Download mode. The steps to access it are as follows.

Note: This assumes you’ve already rooted manually or with Towelroot and know what adb/fastboot is.

How to enable fastboot for LG L90 D415:

First, backup your LG Download mode (laf) with this code, so you can use LG Flash if necessary.

  • adb shell
  • su
  • dd if=/dev/block/platform/msm_sdcc.1/by-name/laf of=/sdcard/laf.img.

Run the following code to zero out laf:

  • dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/laf
  • adb reboot

For whatever reason, you won’t be able to access fastboot via "reboot to bootloader" like most phones, so you’ve got to do a key combo:

  • Power Off
  • Unplug USB
  • Hold Volume Up
  • Plug in USB

You delete the laf partition, which forces fastboot mode and takes the place of download mode.

IF you want to return the phones download mode

  • fastboot flash laf laf.img

You can skip flashing the laf.IMG back before exiting fastboot if you wanna leave fastboot mode enabled instead of download mode. But be careful as without download mode you might not be able to recover from a brick.

So think about what you feel is more useful. In fastboot you cannot flash /system/ back because it is too large.

Disclaimer: This is what i did and it worked. Try this at your own risk, always assume anything you do on your phone will result in a brick and it will be unrecoverable.

  1. I’m going to try this procedure and proceed to unlock the bootloader on my D415. I’m doing this so I can get TWRP and then flash Cyanogenmod. Which of these will wipe my phone? I’m specifically asking when in my procedure to get CM will wipe it. It is currently rooted, but that’s it. If unlocking the bootloader won’t wipe it, then I can back it up with TWRP and flash the new ROM without any worries, but if not, I’ll have to know to back it up sooner.

  2. so tell me something💁
    after downloading the LG laf in the link you provided where actually do I have to put it?¿??

  3. and also the whole of this process doesn’t make sense to me. why??????
    because you guys are not considering the level of people who might read your articles… please at least doing this whole thing and uploading a couple of screenshot can help at least some people from bricking their device(which am include)😡😡😡😡😡
