Here's what happened.

1. Tried to upgrade to newest version of AcidSiri
2. Rebooted and phone got stuck at apple logo
3. Turned off and tried to enter safe mode - unsuccessful
4. Turned off and tried to enter DFU for restore
5. Couldn't get into DFU - apple logo again
6. Turned off again to try DFU again
7. Now I can't turn the phone on again - black screen unrecognized by itunes
8. Since it's not recognized by itunes I don't think it's in DFU mode
9. Tried recboot but reports that no phone connected

Any help would be greatly appreciated. TIA

try kicking it out with redsn0w or TU, use kick out of recovery or fix recovery

you can also try turning it on by holding power and home together for 30 seconds, should go to recovery.

Thanks. I've tried these suggestions. TU doesn't see it as connected. redsn0w needs to get it into DFU which I can't do - the phone never turns on at all.

The power - home button combo does not turn it on.

It's looking like a hardware problem but I can't figure out how a software error could have caused this. I should be able to power it on or at least get it into DFU and I can't. Thanks for taking the time to reply.

That update did the same thing to me...I held the home button while plugging it into the computer (iTunes was already open). It finally recognized and let me restore.

Not working for me. How many times did you try before it worked?

Yeah, when I'm trying to put my device into DFU mode I find the easiest way is to plug it into the computer, open iTunes, hold power button and count to 3, then simultaneously hold the home and power button and carrying on counting to 13, then release the power button but continue to hold the home button and wait (in this case hope) for iTunes to signal a device connected in recovery mode...

Happy ending to this story:

The only way I could get the phone to turn on was to disconnect the battery. I followed the instructions at ifixit (up to step #5) to disconnect the battery and then reconnected it:

Once I reconnected it I was able to start the phone and get the apple logo.

I then used RecBoot to put it in recovery mode. Once in recovery I restored it as new and I'm now restoring from a backup (made before this saga started)

Bit harrowing but all is well that ends well!

Well done!!!

It's a lot easier to remove the battery on the iPhone 4 than it is on the 3GS. I tried.... once.... was a bloody nightmare and I ended up doing permanent, physical damage to the casing.

Thanks. I was amazed at how simple it is. Something to keep in mind later on when the phone needs a battery replacement :)

Agreed!!!

That was my intention with the 3GS and hours later I had a scuffed casing, damaged ego and the same battery in the device as to when I started out!!!!

Will definitely consider changing the battery in the 4/4s though...
