This is all that differs after running fastboot oem unlock
THERE IS NO REASON TO DO THIS YET WE DO NOT HAVE A WORKING RECOVERY OR A ROM
How it works:
[GUIDE] Fastboot for L90 D415 | Optimus L90 | XDA Forum
Because people had trouble and were cutting and pasting and didnt see a period after a file name:
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
power off
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
EDIT: 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.
This is very outdated. We have flashable recovery. Here's a current rooting guide.
