Change DNS servers, wifi and mobile data

@Br1 Hello. is your OTA-2 work / procedure the same for OTA-3 ? Thanks again

Br1

I can’t test ota 3 update, install at your own risk (*)

Br1

OTA 3 Stable channel --- You can reinstall, no changes are necessary.

@Br1 Done, it works as expected.

@Br1 I am on RC test OTA-4, it seems ok for me.

@Br1

New tests.

I noted this:
. Sometimes a reboot is necessary to get my carrier's DNS fully restored if I no longer want to use cloudflare dns. Just using the 'restore' option in the script is not enough.

. When using cloudflare, in the list of cloudflare DNS servers, some are in the USA (Missouri). Is this normal ? Shouldn't cloudflare DNS all stay in its country of origin like I see with Firefox (all in France for me) ?

Thank you to enlighten me.

It could be caused by dns cache, after restoring try this :

sudo resolvectl flush-caches

if it works, I can add it to next version

servers in 120+ countries ... I don’t know what criteria they use

Sorry, i can't confirm it works for me. A reboot is yet necessary.

When i did my precedent feedback, i was in RC TEST OTA-4. Now i am on 'real' OTA-4 and all cloudfare DNS are in my country. So for this, it's solved.

--- New version (only an optimization) here, as reported by @domubpkm to restore the original dns servers reboot is required (added message).

Hi @Br1 . Could you please update your very useful script for Noble ? I'm still using your last focal script which works yet with Noble, but with an error. Thanks in advance.
