Hi - sorry that this is a bit long, but I thought I'd get as much info up as possible.
I bought an iPhone 3G on Ebay as "stuck in recovery mode"... which it was.
So I used iTunes to flash a stock 4.1 FW and got a 1015 error, then through various atempts I tried installing FW in DFU mode and got 3194 error.
Then I used TinyUmbrella to get out of DFU mode - put it in recovery mode & reflashed 4.1 FW and got my 1015 error, so used TinyUmbrella to get out of recovery mode and voila - or so I thought...
When I tried to jailbreak, I tried Redsn0W first and all seems OK - it got me past the activate screen. I then wanted to perform the jailbreak and this is when I realised that I have no WiFi and no service. The no service may just be because its not jailbroken, but the wifi has stumped me.
I think that the previous owner must have updated the baseband and then flashed different FW on it and out of desperation sold (for a very good price ) on ebay.
With that thought I started to look at the more intricate settings and so far can tell you that;
Baseband = 06.15.00
Carrier = O2 8.0
FW = 4.1.0
Model = MB489B
Wifi - has no mac address
Bluetooth - has mac address and turns on!!
I thought that if I downgraded the baseband using Fuzzyband I might get some results, so I decided to try using Sn0wbreeze to create a custom IPSW to include Fuzzyband and perhaps Ultrasn0w to try and either complete the jailbreak &/or get wi-fi working.
Unfortunately without Wifi getting the baseband downgraded is proving hard - I also have no idea what bootloader it has, or how to find out as I cant get a custom FW with apps to load
I managed to find a deb file for fuzzyband (at least it says it is - called "fuzzyband_4.0.iphone.deb") and created a custom IPSW file - but when I try to reload using "shift restore" in iTunes it seems to go through the motion but sticks at a screen with the snowflake on it and the spinning wheel below and the PC just says restoring... eventually it threw up another error. Cant remember what error it was - definately one was a 6015 and I think on another attempt I got error 21 (??).
Anyway - I reflashed the stock firmware and got past the activation screen - so now have a great iPod
I am definately no expert and wanted to cut my teeth a little on this one as it is ages since I played with my own iPhone and I wanted to get up to speed a little.
So any help greatly appreciated... BTW - PC is Windows 7 Enterprise x86 & I have tried to reset network settings!!
Oh BTW - does anyone have thoughts of FW 4.1 or more on iPhone 3G? I have an identical model to above and I upgraded it to v4 years ago (also upgraded baseband) and it was so slow that I downgraded it to 3.1.2 (7D11) and the baseband is still 05.13.04 - when I upgraded there was no jailbreak for 5.13.04 - so it took me ages to get it working again and when I did I just left it alone
OK - perhaps another route for me to try is... does anyone have a 3G custom IPSW which has got Cydia, SSH, Fuzzyband and whatever is the best to unlock bb 06.15.00??
I have tried to cook my own IPSW using Snowbreeze and wehenever I use iTunes to restore (from PWN DFU) it seems to restore OK, but then the phone sticks with either the snowflake with a bite out of it, or the custom restore screen. In either case using Tiny Umbrella to get out of restore mode reboots the phone back into restore mode. So Flash the stock firmware back and yep - its an iPod again
If anyone could help I'd be grateful - please PM me
