I was using my phone normally for the first few weeks i had it, i wanted more apps on my phone and everything started crashing, so i decided to debrand it to a debranded android 2.1 os. I followed this guide on rooting and installing rom manager and downloaded the ROM from the link in here. I flashed the clockwork recovery, backed up the current OS and tried to install the OS that i downloaded and copied onto the SD card. Now here is the problem. When the phone tries to reboot into clockwork recovery, it just fails or something and boots normally. What am i doing wrong?
