I gave this a go, and went into a bit of a panic, as it wipes off CWM recovery for its own (naff) android recovery which is extremely basic compared to CWM. I had a play with it and didnt find it to be a keeper for me, so thought I would put Siyah 2.2 Beta6 back on, and couldnt through its android recovery system, as it would say "signature failed" So, I had to download a Siyah .tar file and flash it via Odin. Thankfully, the Siyah .tar worked perfectly through Odin, and now I am back to safe ground again. PHEW! It is at times like this that you realize just how good, and how much you rely on CWM Recovery. It truly is a Godsend.
