I've crashed and burned at the first hurdle.
OK I thought let's unroot and check if I can get it out of the box fresh and test whether "Triangle away" does the job. I already had the stock Vodafone firmware, so off to Odin (v3.04) I went.
To cut a long and frustrating story short Odin failed, shortly after it had done the "recovery image". Tried a different source and redownloaded the firmware. I can still get to download mode but recovery gives me the stupid warning about using Kies to restore.
Same thing, same point it borked in Odin. Now what?
Tonight is usually beer night (my third love after the wife and kids and tech.) but aforementioned wife is starting a run of six night shifts. Any help (please a bit panicky now) would be appreciated to try later when I'm on my own wifeless, and beerless. Don't make the start of my weekend worse by telling me it's a brick
where there is download mode, there is hope!
