I've hit on an Xbox 360 the same bug described in GTA IV - Out of Commission - Helicopter bug:
I am on the last mission of GTA 4 -- Out of Commission -- and cannot finish due to the bug with getting on the helicopter. The pop-up instructs me to repeatedly hit A, however A is mapped to "run" (and NOT to "jump/climb"). So it never works.
The solutions proposed in the linked Question do not seem to apply to the Xbox platform:
- I cannot use a wired keyboard
- I couldn't find a way to remap the jump key
- I couldn't find a way to set the fps
So how can I work around this bug on an Xbox 360 so as to complete the said mission?

It's actually very easy to work around this. You simply need to press your joystick up (as if you were moving forward) and repeatedly hit A. Then you get on the helicopter in no time.
