@vgr99 hello. I have followed steps 1 and 2, but not sure how to proceed. I want all my data intact, so kindly tell me how to proceed, and when do we get the option to choose home_csc instead of just csc.

[gomathy1998]

Greetings.

Can you kindly explain in a little bit more detail?

And kindly give the steps so that the data in the phone is not erased. 

Thank you.

When do we get the option to choose HOME_CSC instead of CSC? I want to make sure to not lose all my data. Kindly reply asap @ferozukhan

@gomathy...in Odin while adding md5 files...for CSC field add HOME_CSC md5 file to keep your data and apps intact.

It worked for me! thanks a lot! I installed the latest firmware as mentioned by you and selected HOME_CSC and it didn't erase my data.
