The problem lies in the RPM sensor, most likely due to the interrupter cup assembly. The interrupter cup assembly is the black cap that runs through the RPM sensor. You may have forgotten to re-attach this piece or it is probably moving too far out when the garage sets in motion. To fix this, remove the cup assembly, unscrew the two screws on the top metal piece with a 1/8 allen wrench, push the metal piece as far in as possible and put the screws back on. This will give more room for the cup assembly to spin and be read by the RPM sensor. Hope this helps!

2 flashes is a safety eye issue, but you problen is most likely that the chain is not sync with the limit setting. Take the bottom off the gear and sprocket assemble and rotate center limit srew until it is in the same position as the trolley.

My best advise to you is get the brand name remote for your opener. I know it sounds like a pain but click brands are not super great because there supposed to work for many different kinda. For the most part you can call your local garage door dealer and pick one up for your opener. They may sell you a lift master brand opener which is find sears/liftmaster/chamberlain are all the same. Should only be about 35 bucks if you pick it up

The actual problem is after power on the opener, its initial state is uncertain. It may be in ready to close or ready to open state.
If the garage door is in closed position, likely the opener will still try to close it, because its initial state is uncertain. That's why you guys see it travels 2 seconds and reverse.
In order to fix this problem, after you power on the opener, do NOT hook up the chain, and do NOT mount the sprocket cap(so you can see the sprocket travel direction). While you watch carefully at the sprocket, press trigger button on remote control or ask someone press wall control button. Make sure the sprocket turns clockwise and stop. If the sprocket turns counterclockwise, press the control button again, so it will turn clockwise. Let it finish clockwise turn. At this moment, the opener is in ready to open state.
Cover sprocket cap and hook up chain. Mount door bracket and adjust. Your door must be in close position.
You are ready to go.

If you look on the back or side of the garage door opener you will see a small square red/orange button.
Push the button one time, and you will see an amber LED come on. Go to your keypad enter a four digit (of your choice) then press and hold the the enter button until the garage door opener light flashes and you hear a clicking sound. You can release the enter button and it will be reprogramed.
