Help with upgrading

[coryh4225]

I recently purchased an Iphone with 4.2.6 loaded on it. I ran tinyumbrella and the only shsh I could get was 4.2.10.

My question is can I upgrade my firmware from 4.2.6 to 4.2.8? I have the 4.2.8 ispw downloaded but it throws an error when I try and update.

Keep trying. I had the same issue months ago

No you cannot update to 4.2.8 since you dont have your 4.2.8 SHSH blobs. Stay on 4.2.6 or else you wont be able to jailbreak.
