Complete Reset? Advice from those who have done it.

Former Member over 8 years ago

Having been tearing my hair out for months now, I want to try to do a complete factory reset. I see it as 'one last chance' for this unit.

Having done a search, I've come across these instructions that seem to cover the most thorough factory reset:

1. Connect to computer
2. Delete all folders and files in Garmin folder
3. Disconnect from computer
4. Power off Edge 820
5. Press and hold lap/reset and start/stop buttons
6. Press and release the power button
7. Release lap/reset and start/stop buttons after the Garmin logo goes away

Before following these, I just want to check that this is a tried and tested method and that it doesn't brick the device.

Or is there something better?

And has anyone found this approach to solve problems?

Once I've done, I'll build all my settings etc from scratch.

Thank you.

I've also formatted the Garmin drive in the past (on previous devices, not the 820 in particular), I've pretty sure I've seen instructions how to in this sub-forum.

I think you meant this (post #48 and onwards): https://forums.garmin.com/showthread.php?221496-Firmware-3-45-beta-available/page5

EDIT: Just checked through that link. Formatting didn't fixed much, my experience was that some broken allocation units were removed from usage.

I was thinking more like this thread. https://forums.garmin.com/showthread.php?364038-I-accidentally-formatted-820&highlight=format
I get the impression Alan thinks it shouldn't be a problem.

I followed the instructions on post 12 here - https://forums.garmin.com/showthread.php?212075-Edge-1000-Turn-by-Turn-Navigation-Problem&p=546524#post546524

Rather unexpectedly, despite formatting the unit, by the time I had finished the process and re-paired my phone, my old settings were still in place - the data screens were all as I had left them.

I'm sure the format worked because I had to reinstall the maps.

Are the data screen settings backed up to the phone I wonder? Or to Garmin Connect perhaps?

No idea whether the unit will now work any better - time will tell.

In my experience formatting earlier units, there are two partitions. The one you see and can reformat, and one you can't access or reformat. The active firmware and some other files reside in the inaccessible one, so despite reformatting the unit, they'll still be there. I suspect this is the same for the 820.

Yes, that makes sense.

I also did a standard factory reset and that did then reset all the settings. I've now set everything back up as I want and will try it tomorrow hopefully.

I really am fed up with this though. If I could, I'd send it back and replace it with an Edge 1000 which seems to have slightly more mature firmware. Although even that seems to still have problems.
