I've encountered a rather unusual issue. I am currently running CM11 4.4.2 by Munjeni on my Sola, but that's not the main focus of my problem.
Here's the story:
My girlfriend's brother needed a phone ASAP, just for a few days. I was using an iPhone at the time (yes, I know), so I was like, sure, he could have it for the time being. When I got it back, I noticed PC Companion was unable to detect any supported firmware on the phone, and could not restore or update anything (I was on the .10 ROM at the time, with .54 available). Flashtool has given me the following error ever since:
Error in processHeader: 1 : Incorrect Function
(On pretty much all versions of FlashTool, since 9.8.0)
I've verified that all of the correct drivers have been installed, and flashing kernels with fastboot still works fine. I can't flash the original ICS or GB ROMs though, and I'm stumped. I love CM, but if I buy an other phone, I want to either restore and sell this one, or restore it for use as a 2nd phone when that happens.
So, any ideas on how to proceed? It seems flashtool is out of the question to get these FTFs back on my Sola.
