ok recap for me.....
I believe the key for me was getting a complete wipe of everything, including formatting the system, which I could not get before (wipe all: factory reset, format system, format HWuserdata, and wipe dalvik cache also) then very importantly (so it seemed) mounting the system before executing the install of the hwu8681.zip file.
1. I completely Changed my image folder with theses files https://drive.google...WnVNdHZlbkRwWTQ
2. I changed the Recovery img to CWM to the one you linked to above http://www.droidrzr....awei-mytouch-q/
3. I changed the boot img to the one you linked to above http://www.droidrzr....awei-mytouch-q/
4. Then deleted the cust.img file (I have no idea why this is important if it is at all, but it works so I am not going to try to figure it out, but someone knows please tell me why deleting this is important)
5. Booted the phone into recovery mode (CWM)
6. Wiped everything: factory reset, format system, format HWuserdata, and wipe dalvik cache
7. Then I mounted the system in mounts and storage (which I was not doing before and don't know why this needed to be done, can someone explain why that is needed on this device)
8. Then Flashed the hwu8681.zip file to the device and rebooted. Took a long while to reboot but once it did all was well and the U8680 is now a U8681
Everything works just fine. Blue tooth, calls, camera, keyboard, so far nothing that I can find that does not work. Much better phone now. And Zero T-Mobile Bloatware! Thank you all!
For Some reason, on several tries I could not format system, I had to reinstall the CWM Recovery numerous times before I could do this.
