I switched to 22.214.171.124 from UD10. After wiping data and cache, and installing the new rom, the UD wallpaper was still there. I changed it to something else and continued to set my phone up. Later I tried to install the Red Rum theme to give it a look. I had problems trying to get it to take. I tried to reflash the ROM and try again. This time I manually wiped data and cache 3 times each and continued to reflash 126.96.36.199. Same thing, my new wallpaper was on there when it finally booted up. I haven't tried the theme again yet. I'm trying to figure out why my wallpapers are lingering from rom to rom when I am doing wipes and resets. Any clues?
