MPU-9150:what are the steps of Initialize and enable FIFO?

what are the steps of Initialize(just using accel & temp) and enable FIFO(just using accel & temp)?

A. Initialize(accel & temp & cycle mode)
Here are my setting steps for the MPU-9150(using cycle mode and without FIFO):

step1. The register 107 is set to 0x80, do a while until reset is done.
//reset MPU-9150 (all register value = 0x00)
step2. The register 25 is set to 0x18.
//setting sample rate to 40Hz (=1000/25)
step3. The register 28 is set to 0x00.
//setting accel's full scale range = +-2g
step4. The register 26 is set to 0x04.
//setting accel's low pass filter bandwidth = 21Hz
step5. The register 56 is set to 0x01.
//enable INT
step6. The register 107 is set to 0x20.
//open cycle mode
step7. The register 108 is set to 0xC7.
//setting cycle frequency to 40Hz, disable Gyro

It can work,
I do this right?
what is your setting steps?

B. Enable FIFO
There is same setup steps for FIFO program.

step1. The register 107 is set to 0x80, do a while until reset is done.
//reset MPU-9150 (all register value = 0x00)
step2. The register 107 is set to 0x00.
//close sleep mode.
step3. The register 108 is set to 0x07.
// disable Gyro
step4. The register 28 is set to 0x00.
//setting accel's full scale range = +-2g
step5. The register 26 is set to 0x06.
//setting accel's low pass filter bandwidth = 5Hz
step6. The register 26 is set to 0xC7.
//setting sample rate to 5Hz (=1000/200)
step7. The register 106 is set to 0x40.
//enable FIFO
step8. The register 35 is set to 0x88.
//accel & temp data into FIFO

After setting, when I read register 114 & 115, the data is 0.
I should be the wrong way, Could someone help me?

I went to the "Github" website has seen many example programs,
but most of them are DMP application, I can't fully understand them.

Thanks for read my question!
