LG Optimus V Custom Recovery: LG Phone Problem and Solution

To use copy flash_image and recovery-thunderc-v-1.2.0-GNM.img.zip (both unzipped) to the root of your sdcard. LG Phone Problem and Solution

To flash: via adb shell or terminal type this from root # shell, code:

  • mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
  • cat /sdcard/flash_image > /system/bin/flash_image
  • chmod 755 /system/bin/flash_image
  • mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
  • mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system
  • flash_image recovery /sdcard/ recovery-thunderc-v-1.2.0-GNM.img
  • reboot recovery


















Trouble shooting
1. If you get an out of memory error reboot device and do it on a fresh reboot.
2. If you get a file not found on the "mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak" skip it and move to the next step as this file will not be in your rom unless it has recieved an ota-update and if so needs to be disabled. LG-Optimus info
Key combo to boot custom recovery from powered off is Vol down+ Home +Power and release at LG Logo or use adb reboot recovery from adb shell.
