If you root your phone should you do OTA update? I am rooting my xiaomi phone.

I am using instruction here

The truth is I actually prefer to wait till I have an update. Device enscryption for xiaomi doesn't work yet. Some said it will work for miui 7.1

Well, I go ahead and root it anyway.

WHat about if latter miui 7.1 is available?

Should I just do OTA?
If you update your rooted phone you will lose your root access and will need to root your phone again which could be a problem because previous method of rooting may not be working on new version. You will need to wait until the same rooting method you used earlier releases a compatible update or you might need to find a compatible method.
