Again I have managed (after much experimentation and frustration) to get a "bricked" iPhone working again, using a different method.

THE SYMPTOMS

• iPhone appears to have no baseband.
• iPhone shows "Repair needed" and the info button shows unknown IMEI and ICCID.
• When you restore - even from DFU mode - the OS changes but the firmware never gets uploaded. Restores take ages and eventually timeout with an error, leaving you in Restore mode.
• You can bash out of restore mode and boot normally using the tools available, but you still get "Repair needed", etc.
• Settings / About shows WiFi greyed-out, all 0s for Bluetooth, and nothing for baseband info.
• No signal (obviously)
• No sound from keypad or ringtones.
• When you try jailbreaking using ZiPhone or iPlus, it fails during the process. (If I recall, ZiPhone says "Hmm, what did you do...?" and then fails to unlock. It scrolls forever. With iPlus you get the red banner and text but it stalls and locks up.)
• After you've tried ZiPhone/iPlus, your phone will not boot in normal mode. You get "AppleMRVL868x: Invalid calibration data in device tree" in the scrolling white-on-black text.
• Eventually you might be left with "BSD root: md0, major 2, minor 0" scrolling continuously.
• From this point you can Restore in DFU mode but it still won't restore the baseband and will take ages to time out. You can get it to boot again but you're back at square 1.

POSSIBLE SOLUTION?
Here's what I did. I really hope this helps some others too.

1. Found iPhone firmware 2.0 beta8 build 5A345 and iTunes 7.7 prerelease version (which can flash firmware beta 8)
2. Installed iTunes and restored 1.1.4 (got error 1011)
3. Restored to 2.0 beta 8. Of course it was not activated BUT I got IMEI, ICCID, audio, bluetooth and Wi-Fi back!
4. Pwned the iPhone.
5. From restore mode, restored a custom 1.1.4 which successfully reflashed the bootloader and baseband unlocked the iPhone.

Good luck!

Can you please explain these steps further for us? I really want to make sure I am doing everything right here! Thanks a lot.

No I'm not going to write out step-by-step instructions at this stage - that takes a long time and a lot of careful thought. There are plenty of people here who can follow the steps as I've provided them. How to perform each step has been gone over countless times elsewhere. Better to wait and see if someone else can confirm it worked for them, for now. Sorry to seem harsh.

I am stuck trying to get the 2.0 to flash onto the iPhone. I keep getting an error 1600 or 1603 from iTunes. I am using the 7.7 iTunes.

I have tried everything, restarting computer, need user account, different wire, DFU mode, non dfu mode, cant do anything!

And FYI when I restored to 1.1.4 I got an error 1102 not 1101.

I have the same situation as zeve has. Nothing helps, I've tried almost everything. Does anybody have an idea how to solve the problem?thanks

This is a useless solution.

Well thanks for your valuable input, MickieF. The fact that it has fixed my iPhone, where nothing else has worked, implies otherwise.

The majority of replies here are from people who can't figure out how to get the software needed, which I cannot link to. Are you like those people - or have you actually tried it and found it didn't work? If so, it would be more helpful for the community if you gave some details.

The ones who do have the files needed cant get this to work either..
