Hey there!
Okay, so I recently rooted my LG Optimus L3-8C (E400) running stock rom and version 2.3.6 Gingerbread (yuck) and I followed all the instructinos from this video:How to install CyanogenMod 9 on LG Optimus L3 E400 + MIUI and Annobox downloads - YouTube
in order to flash the CM9 ROM. Problem is I can NOT reboot into recovery no matter what I do it seems. When I try tp reflash the CWM recovery it tells me 'sucessfully installed!' then when I press 'reboot into recovery' it gets stuck on the LG logo for so long I often have to hold the power button to go back to my device. I even downlaod 'recovery flasher utitlity' found herehttps://play.google.com/store/apps/details?id=acr.recovery.installation.utility&hl but, whenever I run the app it tells me 'no recovery.img' found onexternal SDCARD even though I placed it there! I tried to fastboot but whenever I run CMD it tells me ' 'fastboot is not recoginzied blah blah blah.'
SOMEONE PLEASE HELP ME :(
