Firmware Update Questions

[jerry0]

I see one of the threads here is locked so i can't post in the thread.


I was going to update to the new firmware few days ago but didn't because my internet has been down/lagging issues and im still trying to get it fixed.




1.  What happens if your internet goes out when you doing a firmware update?  Any chance it bricks?  Or does it just not go through and you can do it again?  Anyone here would even try upgrading firmware if their internet isn't stable?




2.  I have done previous firmware updates before and recall one of the earlier ones I did, i had that bootlogger mcu issue a while back.  But do things like this still happen with the firmware updates now?





3.  I recall they do ask you to confirm the identifier number is correct during this process.  Has there ever been a case of where that number wasn't displaying the same number on your nano ledger screen?




4.  What happens when you update much older firmware like 1.5 all the way to firmware 2.0?  Does it just by pass 1.6.1?  Does it increase chances of a an issue in the update?




5.  I'm curious but anyone here still using old firmware and by that i mean using firmware before 1.6.1?  I know people say you should always update to the new firmware when its available but anyone here still using old firmware but have no issues using it with ledger live?  I assume if you continue to use old firmware and continue to use ledger live... you might have synchronizing issues or things like that until you do next firmware?

Nothing will happen. It doesn't update until the entire firmware has been downloaded and verified. If your internet dies during the download, it will just abort and you'll be able to try again.

2.  I have done previous firmware updates before and recall one of the earlier ones I did, i had that bootlogger mcu issue a while back.  But do things like this still happen with the firmware updates now?

Not unless people are updating older firmwares when this was an issue.

3.  I recall they do ask you to confirm the identifier number is correct during this process.  Has there ever been a case of where that number wasn't displaying the same number on your nano ledger screen?

No

Pass...

Don't think you can... I vaguely recall that Ledger Live only works with newer firmwares (ie. v1.6.1 etc) and required that you update before using it.

I recall being 'forced' to update my firmware when I connect it to the latest Ledger Live. But you can connect it to Electrum or other apps just fine. Don't know why you want to use outdated firmware if there's a major security update or a new feature that you like though.

Pass...

There is no 1.5 firmware version, but there is a 1.5.5 version. If your device has version 1.5.5 installed, you can't go straight to 2.0.0. You have to first install 1.6.1, and then update your 1.6.1 to the latest 2.0.0.

It's all explained here > https://support.ledger.com/hc/en-us/articles/360002731113-Update-Ledger-Nano-S-firmware.

Forced how? I have never seen that happen. How old was the firmware you were using that they forced you to upgrade it, and how do they even do that? The upgrades are only accessible through the Manager tab. Did Ledger Live allow you to send and generate receiving addresses?
