Installing e on an LG D855 first time user

I just got an LG G3 D855 and I’m trying to follow the install instructions. From Ubuntu terminal I try ```
dd if=/sdcard/twrp-d855.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery

I tried changing the name of the twrp file to the one I downloaded 
sudo  dd if=/sdcard/twrp-3.3.1-20200316-d855.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
I get dd: failed to open '/sdcard/twrp-3.3.1-20200316-d855.img': No such file or directory

Hello and welcome.

Are you su or sudo user ? You can ’ lock’ your shell as root with:

  • su -l then password (no echo)
  • sudo -i > password.

Don’t forget to launch exit to come back with the user prompt ~$ without admin. power

For what I’d already read, you may rename your exact device’s recovery as twrp.img (at the SD root) before flashing with dd command.

Or use sudo su - :wink:

No sudo :rage:
