Got a tender, left it on for a couple days, updates still failing. It's no longer offering me this update however and has moved on to one of the other updates, which is also failing to install. I give up!
Haven't been able to find my tender yet... been meaning to just stop by HF and pick one up to try it out. I saw someone posted about setting parking brake so added that to the list of things I've tried, still no luck!
I have tried about everything I can think of to get this update to install. I've never had an issue with any prior updates, but have tried probably 30+ times to install this and it always fails. Have tried 12V battery disconnect and reconnect, BMS resets, long drives, update now and scheduled...
I got the 4.2.1 update last week, modem came back for a day or two, but then dropped out again. It's definitely not fixed for me. Dropped the truck off at the dealer this morning.
