iPhone 3G - restored to FW 4.2.1 BB 06.15.00 - HELP
I decided to sell my old jailbroken iPhone on a well known auction site :)
But - I thought I would do a factory reset before shipping and during the process it locked up. So I connected to iTunes and let it do a restore to 4.2.1 from the web. However I forgot that when it came back it would need activating etc.
So when it was back, I used RedSn0w 0.9.6b5 to jailbreak and all seemed good - loaded Cydia and Ultrasn0w 1.2.7, but get now get no service and says "searching" for ages.
I have looked about and found various ways of fixing this - but the common factor was to upgrade the baseband to 06.15.00 (iPad) which I have now done - but still cant unlock it. I have also tried restoring to 4.1 and 4.0.1, but nothing :(
It has now gotten worse because with having tried various unsuccessful methods (including Sn0wbreeze, L1merain, etc) the phone boots and shows the Apple icon - but thats it. I tried restoring on iTunes again to 4.2.1 but it always shows a 1015 error (expected) and then when I check using TinyUmbrella it still shows FW 4.0.1 despite doing a restore to it when in DFU mode from iTunes.
I have tried so many different methods now I am struggling to remember all the permutations - so please ask and if its something I have already tried I will let you know!
I am now losing the will to live - can anyone offer any advice?
Thanks in advance. :fail
