How to unlock bootloader on LG Spectrum 4G

There is a good news for you that finally after countless hours of research, testing, and scripting, we have a unlocked bootloader for LG Spectrum 4G ICS.

This uses the bootchain from GB with tdm’s 3.0.8 kernel for cm9, and several tweaked files from the Spectrum’s ICS itself.

What’s this do?

  • Installs root
  • Installs the unlocked bootloader from gingerbread
  • Installs CWM Touch 6.0.1.1
  • Checks the md5sum (twice) on each image before flashing them to verify their integrity

Requirements

  • Be on the ZV7 OTA or cab.
  • This is to ensure you get the new radio(s)
  • This has not been tested on Gingerbread nor supported for GB.
