Isn't there any other way? Can't I use the unbricker?
Is there a guide for that update via other ds or dslite?
I might have someone with a dsi, will it still work?
Yes, you can use a DS of any variety as long as it is not a 3DS on 3.0.0-6. That is in fact your only option. Find someone who will let you use theirs.
As far as a tutorial is a concern, it can't be any easier really. Assuming you have already put the kernel files on your SD just put the updater file on your SD and then run it from the EZFlash's menu and follow the instructions.
To use the unbricker you are going to need a DS fat or lite, BTW. You can't use it on a DSi or newer model. Good news is you don't need to.
