Now run the following code to zero out laf:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/laf
adb reboot ""
I downloaded the files but I don't know how to bring up the adb thing command prompt. And How do i back up LAF?
Have you installed the LG Device Drivers (can be found on LG webpage), as stated in the thread? And downloaded and extracted the linked files? If no, do so. If you have installed LG Device Driver and extracted the adb files, connect your phone to your PC, go to the extracted folder, hold shift, right-click on adb.exe and enter the stated commands. The commands will automatically back up your laf to your SD card (the laf is a mandatory part of your phone system, so a back up is highly recommended, so you are able to flash it back in case anything went wrong). After you have entered the command "adb reboot" your phone should reboot. Now start the fastboot.exe as administrator (right click -> run as admin) and continue with the guide. If you have further questions, you might ask @shinobisoft
, he might be able to help you even more.
But as I am not 100% sure about all those stuff (as I have a D405 and did all this some month ago), please do some further investigation, otherwise you would end up with a bricked device.
