I am totally at a loss here. I reformatted my SD card to FAT32, downloaded this 139mb beast of a file, and placed it in the SD card root. I got into HBOOT but no "request to install" pops up. I have to go into Recovery and try to install the .zip file. The result is always the same, the screen flashes as if something is being installed and then flashes back to the recovery screen. No downgrade, no nothing.
Any ideas what's going on here? I do not have a leaked OS installed and no ROM; I do have a hydra kernel and my phone was rooted via Unrevoked3 and Unrevoked Forever.
EDIT: I just noticed my baseband is 1.00.03.XX.XX. Would that have an effect on why I can't downgrade?
