I kind hoped the conclusion would be that you could unlock hidden features in the brush head, increase the torque and reset the head so that you don't have to replace it. But alternatively, since the head has an NFC tag, could you use it for stuff like a partnership with Marriott (open your hotel door with your toothbrush, so much convenience) or with transit companies to charge your monthly transit pass? Possibiliti…

Right!?! NSFW features like the Oral-B brush has, where you can order a special brush that helps you relieve certain stress in the bedroom. With the modified Sonicare firmware, the brush won't stop after 2 minutes but keeps "brushing" until, well, you're 'done'...

I’ll never forget when my damn sonicare toothbrush app warned me about my iPhone being jailbroken. Had to have been a troll by the creators of the app since not even some of my banking apps had that warning.

I wouldn't be surprised if the apps did notice, but didn't take any action because it might be a hairy legal problem if they get between you and your money.

Me, dumb: I change my Sonicare toothbrush head whenever it tells me to. I haven’t had a cavity in 8 years. You, a clever toothbrush-hacking genius: haha, the head is new again! This is neat, and I find the process of reverse engineering the Sonicare toothbrush fascinating, especially sniffing the NFC communication, but please change your toothbrush head every three months.

I got mine to buzz, but it never prevented me from brushing my teeth.

Earlier quoted context omitted.

The toothbrush doesn't force you to change the head. You can brush your teeth with an old head as much as you want.

Yeah but if you could reset the head instead of having to change it, imagine the savings

I have this brush and would highly encourage you to swap the head when the brush asks you to do so, for the sake of your dental health.

I have it as well and at this point used the same head for 5 months. There's no visible deterioration and I exceed the recommended brushing time by doing 5 instead of 3 minutes. Why exactly is the head only good for 3 months?

Mine doesn’t just blink; it keeps doing this annoying fast vibrate/noise whenever I stop brushing. So I was reading the article really hoping for an easy jailbreak at the end.

I would question your priorities if you're trying to save on $4 heads for a $90 toothbrush.

When I rooted my android phone a few years back, all of my banking apps worked (I had to use magisk hide for some I think) but the only app that would not work was the Macdonalds app... Not that I needed it, I never go there, but I thought it was funny that their app was more "secure" than some banking apps.

I can tell you from a few weeks ago that Santander definitely does care and magisk hide does nothing for it

Brushing your teeth for too long can have bad effects on your dental health[1][2]. The heads loose their strength over time and if you replace that with pushing harder, you might also overbrush.

Banking apps locking you out when jailbroken is a major pain point for those who do, so I doubt that there is any legal issue.
