[Madan56789]

Hi All,

Can anyone confirm if it is possible to flash S21 thru Odin without loosing phone data and configuration? Samsung India is delaying OneUi6 so considering flashing thru Odin

You can do it but on your risk. But wait for official update from Samsung this week probably you will receive.

You can flash via Odin without data reset.

The firmware file ships with 2 csc files.

Home and normal csc.

More info can be found on Google or sammobile about csc

Thanks, will it retain esim data or esim will be erased?

[Corgi]

Use the home csc file while flashing to avoid factory reset

I would suggest you to wait for Offical firmware from Samsung. Do not force install the US firmware on an Indian device. You might face issues with wallet, upi, etc.
