I can't get into ClockWork, I always needed the bootstrap to reboot to recovery for me..... And I tried flashing that in the Android recovery, but it can't verify a signature...
Ok, so let me see if I understand all I know about your situation..bear with me as I am medicated and have slept less than 5 hours in the last 5 days...:icon_eek:
1) Your phone is completely borked, and so far, nothing you have tried has worked...
2) Your battery is dead, and as of right now you have no way of charging it or swapping to a charged battery...
3) Each time you have tried to flash or SBF it has failed due to "not being properly signed"...
4) You can get to Bootstrap, but you cant load an update.zip...fails due to signing issue...or, you can get into Bootstrap at all?
5) When you say
"I can't get into ClockWork, I always needed the bootstrap to reboot to recovery for me"...does this mean you cant get to Bootstrap and ClockWork at all and you are trying to go through Stock Android Recovery -Power+Home button?
It seems that to do anything at this point to try and get you straight, is going to require a charged battery...so that is the most important step. After that, then you need to make sure you can boot into Koush`s Bootstrapper and navigate to either the "maderstock.update.zip", or some other file to flash...and see where this goes. If that fails, then I believe you are going to have to go through RSD Lite and do the full SBF Flash that way.
Now granted, I havent had a ton of experience doing this, but I am about 85% sure these are the initial steps you want to take...and if I am wrong, I am 100% sure some one smarter/more knowledgeable than me will correct me...
Good luck, and keep coming back here...sooner or later you will get her up and running again...
