Hi, I am new to this rooting and flashing world. So far I have unlocked the bootloader on my Ascend Y300, installed ClockworkMod Recovery v22.214.171.124 and have downloaded the latest nightly build of the 4.3.1 ROM zip.
When I try and install the package from CWM it fails saying '(bad)', I wondered if the download was corrupted from the nightly site, so I tried in Firefox (had used Chrome) before but still the same. I have been trying to install from the external SD card, so I moved the zip to the internal storage, but still the same error occurs. I have not tried an earlier nightly build, could this be worth a go?
