Battery problems with Jailbroken 3GS
I got a 3GS last August and Jailbroke it to version 3.0.1, it's remained that way since and has worked fine. Last week, the battery performance nosedived to the point that the phone lasts about an hour now on standby before dieing, it then takes about half hour in a charger before showing any signs of life.
I've heard that a Restore might be the next thing to try before taking it back to the place I got it from (obviously un-jailbreaking it first).
When I tried to Restore using my 3.0.1 IPSW file via iTunes it came up and said something about unable to verify device (sorry, I should of made a note of the exact error), googling the error it seemed that the Restore was contacting Apple to verify it, Apple wasn't verifying the Restore and was coming up with the error.
I then placed the following in my Hosts file so that the Restore got fooled into going to Sauriks server:
I have SHSH files at Sauriks server for 3.1, 3.1.2 & 3.1.3 but I don't think Saurik stores 3.0.1 SHSH files so I assume this is where my problem lies ?
I'm not sure what to try next, would I be best off getting a custom 3.1 IPSW file and Restore using that ?
