My Oppo r7 Plusm is not working.
I try to root the phone and it stuck in a boot loop. After that i try to hold up button and power off button. Now its not working. How can i fix it without deleting any data?

So you messed around with the phone without backing up your data? You've learned the hard way. You will need to flash with stock ROM from here and wave goodbye to your data [ROM][STOCK] Official R7 Plus Roms | R7Plus, R7PlusF, R7PlusM [15 Sep 2015] - R7 Series | 3rd Party Development - OPPO Community
