I am currently new to xperia l. I unlocked the bootloader and installed cwm, twrp and philz recovery but none of them seems to be able to flash ANY files. I've checked all the zips. I can't install cm11 directly, i have to extract the boot.img, flash it and then only flash cm11 ROM. All of the recoveries gives me e: can't install xxxxx.zip (bad) and other errors even with the cm11 zip now i have flashed and is working. What should i know? What am i doing wrong? Please help.
