Dont worry nothing will be broken in ecu.
Just charge battery long as you can, try again and if cable wont connect after lots of attempts get another cable.

Also had some nightmare and sleepless night experiences in this department, what has worked for me was to do the following
1)Charge the battery before you intend on flashing, preferably the night before
2) Before you flash, disconnect the battery for 10-15mins, this enables the ecu to clear out its cache
3) If your fortunate to have another car at your disposal, use a set of booster cables and connect it up to your car, whilst the other car is left to idle ( Whatever you do, please just dont start your vehicle at any point in time with the cables connected, as you could fry your FRM)
4) Connect your battery charger in supply mode to the front of your vehicle ( I know this seems a bit overkill, considering you already have a vehicle connected to the rear battery )
4) Ensure that your phone is fully charged and in aeroplane mode
5) Have just the ignition on the car On, and then commence with your Flash
The Above process has never let me down and iv flashed my car and friends vehicles, multiple, multiple times
