...ufff!
You make, manny,manny wrong steps.
To solve:
First, you need to set baudrate of COM to 115200 bauds, not to 921600
Second, if you use the AllbugsGold procedure, you NEVER connect to your phone with the normal way....only with TP.
So, download X65flasher, one good fullflash of Siemens C72V phone (for AMD flash) and papuautils 1.1.1c.
- start x65flasher with the DOS command "x65flasher /b" (enable bootcore writing).
- connect your phone, set baudrate, COM and testpoint option.
- click on Connect, make testpoint, push shortly on the phone red button.
- after ignition, disconect testpoint (have 3 seconds). On the down part of window you will see C72 bootcore identification.
Now click on Flash button, load fullflash file (from where you saved) and click on OK. Confirm the bootcore writing and wait...40...50 minutes
After finishing, close x65flasher and open papuautils.
Go to Flash menu, set COM, baudrate.
NOW CHECK ONLY ??????OTP, Recalculate Keys - in Flash (automatically is checked other 3 options) and Pause. NOTHING ELSE!!!
Click on Do the Job! quicly make testpoint and push on the phone red button.
See on the right window, disconnect testpoint and wait to finishing (2 minutes).
Now close papuautils, disconnect cable and...power on your phone
If you make exactly the all steps, your phone start and working.
That all!
