Stuck in bootloop
So, i rooted my LG Optimus F7, I don't mess with flashing ROMs and what not, i just wanted a wifi tether and a few special features you can have with root. WELL I created a restore point on my SD card, and i thought well why not see if it works. SO I checked it out and it said MD5 error or something along those lines, which I fixed with the replacing the Nandroid.MD5 file, cool. So i tried to restore my phone again and it said Error while restoring /system! to which i thought awesome another error i have to figure out how to fix just in case i need this in the future, well to my surprise when i hit Reboot system now, it said i had lost my root, would you like to root your device >yes >no. I was caught off guard but i figured well yeah i came in with a rooted device so im leaving with one. well its been stuck in boot. i did battery pull, i can get into recovery mode, and my laptop recognizes i have a device hooked up to it. When the phone is off and just plugged in there is a very simple font and it says something along the lines of battery charging png 03 missing... I'm a little panicked, can someone please help me fix this.
