I'm running the FRG22 leak and have the apparently-well-known issue with SetCPU not getting its root permissions during boot. Once everything is up, the profiles service asks for and receives root no trouble, but apparently there is a known bug with Superuser 2.2.x that it doesn't like SetCPU or vice versa and the solution is to downgrade to 2.1.
Problem is that I have SPRecovery on my Droid 1 (not Clockwork/ROM Manager) and all of the signed Superuser 2.1 zip files fail with "Installation aborted" for me. The file really is named update.zip (not update.zip.zip), and I've flashed plenty of things with SPRecovery before (including a couple/few ChevyNo1 kernel swaps earlier today) with no trouble at all.
I feel like I've done my due diligence and have Googled and searched here for several hours looking for reasons (other than silly .zip.zip ones) why I'd get "Installation aborted" in SPR and haven't found anything that helps. Heck, I'm tempted to just take the su and Superuser.apk files out of the Superuser-2.1-signed.zip file and manually put them in the right places using Root Explorer. If I weren't afraid of breaking the symbolic links or otherwise screwing it up that's what I'd do. I'm not a Linux guru but I'm semi-functional due to being an old school DOS guy.
Anyway, I figured rather than charging boldly forward and doing something that made me wish I'd asked for guidance first, I'd just ask for guidance first. I'm guessing that these zips are just not signed with a key that my SPRecovery likes or something and maybe I just need the right update.zip to downgrade my su/Superuser.apk to 2.1. Not sure at this point. Thanks in advance for any direction.
P.S. Over on XDA-Developers it looks like they've released a Superuser v.2.3 that is also supposed to fix the SetCPU issues. They have a signed .zip that is specifically for Eclair/Froyo but it too fails and says "Installation aborted". It might actually be a happy thing that it did because when I went to the last (most recent) pages of the topic it looked like lots of folks were having trouble with it.
