Select all md5 and HOME_CSC except CSC if you want to retain your data and apps.

Hi feroz, as you know we are already getting blue downloading screen:

1) can I directly connect my phone using USB cable and start performing the downgrade.

2)Which all md5 files to be added, i dont wanna lose my data?

developer option is not enabled in my phone before crashing.SO can i still go in Odin mode?

[ferozukhan]

Yes, you can directly connect to ODIN as it is already in Downloading mode.

Select all md5 and HOME_CSC except CSC if you want to retain your data and apps.
