I am going to do a router power cycle, try to flash immediately after, see if that helps. If not, I might have to wait to do a full reset and reconfig from scratch.
Things to try:
Try clearing Browser Cache.
Unplug any USB ad on devices.
Electrical Reset Router followed by immediate flashing.
Edit: you are on a new router, when you converted from stock to rmerlin you were supposed to do a factory reset with the box checked to clear the entire unit before setting it up.
If after the above, if it still does not successfully flash, then you need to "Restore" to get it going properly.
@John Fitzgerald The power cycle did the trick. Earlier, I did a power cycle when I tried the upgrade a second time but let it sit for several long minutes before having a chance to try the upgrade. This time, I grabbed my laptop, sat next to the router and did the upgrade as soon as the router came online after the power cycle. Worked like a charm.
Thanks!
