+# Notes\r
+\r
+With the release of v1.5.0, NAND flash support is not available yet. Before upgrading the router,\r
+the u-boot environment variable `bootcount` needs to be set higher than 3. This can be achieved\r
+by ssh'ing into the router and running : \r
+\r
+\r
+`fw_setenv bootcount 4` \r
+\r
+\r
+After rebooting the router,the router can be upgraded using a `nor` image. When upgrading, it is important that any settings\r
+are not saved and that the "Keep Settings" box is unchecked in luci or that the `-n` flag is specified when using `sysupgrade`.\r
