  2. Diego says:

    one more thing, you put 3 download links, we have to flash the 3 in order ?

    1) rollback package, then
    2) Marshmallow Stock Rom, then
    3) Marshmallow version: BLL-L23C605B120

    that is the correct way?

    Hello, I have a problem. When I did the upgrade using the other post I get a compilation number NRD90M test-keys. I don’t know how to fix it because I don’t know which is the data file you are saying. However, I try to install the rollback package and it doesn’t work. The compilation number still the same NRD90M test-keys. Please help me.
