The error message says that it did not find an SLB. Assuming that you did install the SLB properly, that you did save the partition table before resetting (seeing as you can read the drive), the other possibility is that your UBoot env variables have been messed up. In the UBoot prompt, type printenv and tell us what it says. Also, does UBoot list your hard-drive on startup?
Another possibility, although unlikely, is that you didn't install the correct file as SLB. It's been years since I touched this, but it should ask you to select a file as SLB. Make sure that you choose the right one.
This is one of those situations where I would say "give me the keyboard and I'll take a look," unfortunately you're way too far away for that.
