From 64ece84854ae49f40e9b9d4d88502247774f9d2f Mon Sep 17 00:00:00 2001 From: Steve Rae Date: Tue, 7 Jun 2016 11:19:35 -0700 Subject: fastboot: sparse: remove session-id logic This "session-id" alogrithm is not required, and currently corrupts the stored image whenever more the one "session" is required.
