There is still air in the master most likely.
Start with a master bleeding kit. It will have lines that put the fluid right back into the master. You need to do this until no more air is in the return lines. Then reconnect the lines and start bleeding the system as you have been starting rr, lr, rf, lf. You shouldn't need to bleed the ABS valve. Enough fluid will pass through it.
If you can't find where the air is after that, clamp the soft line above the rear axle and clamp both soft lines on the front. While someone is depressing the pedal, release the lines one at a time. When the pedal falls, that is the one with the air in it. Bleed that one and try again. With all lines clamped it should feel like a rock. If not, it is in the hard lines or the master.
The swishing sound is normal, it is vacuum in the booster.
Good luck....I hope this helps...
