Without intending to get in the way of aus9's good intentions, if your phone is "near" dead, one of the most probable ways to get it back to life is by using sp flash tools. You say it's still recognized so it can still be flashed by flashtools, so stick with the windows xp and flashtools.
To bring back your phone to life, flashtools doesn't need to have adb working, it uses the preloader drivers (which is not the same as the phone's preloader) to communicate. These are the ones activated when connecting your usb to the phone when you flash or readback in flashtools.
Your phone doesn't charge or get into fastboot/recovery so it is likely the preloader is shot-off into neverland.
Since you have a complete backup, first thing to do is flash the original preloader using flashtools in download mode.
Next you should flash mbr, ebr1 and ebr2. Then uboot (or lk.bin) and logo.
At this point if you reboot your phone you should be able to get into the recovery menu using the appropriate key combo. Do not try to activate any of the options, it will not work since the recovery.img still needs to be flashed.
That will be the next step, just stick to your stock backup for all of this, later you can try custom recoveries. First thing is to get your phone working again so you should always stick to your original backup.
After flashing the original recovery, see if you can get into it, if that works, flash the rest of your backup and it should bring your phone back to life.
I would advice against dismanteling your phone at this point. It might provoke more problems then needed, just have a bit more patience.
