Hello all, I have a Y6 scc-u21 that I would like to flash to get rid of the root. Now my info is this:

Firmware: B150
Build Number: SCC-U21C185B150
Cust Number: CUSTC185D004

Now I found a ROM file to reload up but it is this info:

Firmware: B150
Build Number: SCC-U21C900B150
Cust Number: CUSTC636D001

What I would like to know is if this file I fould would be on for me to flash on my phone or not, and if not, where can I find the one that I could use?
