Okay, one more hint before I'm off for a while. You absolutely need to get the OTP.bin, but @Normmatt should have you covered. Iirc, there's a 1.0 OTP dumper made by him (why didn't you search for this in the first place, btw?). This one may help you, too:I am currently examining the NAND with someone, and won't be able to give you further instructions until we find out more about your situation. Please continue to keep your system on: Sorry for the inconvenience!

It was tested by @al3x_10m, and I gave advice in the development of it, too. It works fine, but all the warnings in the readme apply. Don't let any inexperienced user handle this!
Also, the way it is now, it is possible that a hardmod will be required sooner or later. If you pay attention and do everything in the correct way, as I described it, I'd say your chances of doing this without a hardmod are roughly ~80%.
