Here we go:
I recently rooted my S-Blaze 4G using Odin to flash a tar.md5. No problem there. More recently, I installed CWM Recovery and Rom Manager in order to flash .zips. That also went fine, and my phone boots into CWM Recovery without a hitch. I've backed up my phone. I was getting ready to flash a T769UVLH5.tar.md5 (that's 4.0.4 -- upgrading from 2.3.6) using Odin so I could next try out CM. Lo and Behold, I can't seem to get into download mode anymore. Every time I try, all I get is CWM Recovery. I've looked around everywhere and can't find an option to boot into download mode, searched for an alternate key combo and I can't find one. CWM seems to only flash zips.
Am I doing something wrong? It seems so simple that no one else even has this problem... I guess I really am a noob
