stuck in a reboot loop help!

Mine did the same this morning. Can't reboot with hardware keys

OK, so after all these posts… no answer yet….This is killing me…I also cannot hard reset this watch… Earth to Samsung…help!!!

Seems like this watch has very bad water resistance so if you get a little water or sweat it will go in through the speaker and cause this to happen to your watch. What you need to do is open up the back of your watch and clean it out with a little of alcohol.

Good luck

Bit late, only came across this while looking to solve the same problem. Took the back off and dried it for a couple of minutes with the wife’s hairdryer, solved the problem. Almost certainly moisture ingress as I had been for a run and been sweating like at the proverbial horse just before it went into reboot mode.

I called samsung tech and they told me mine was locked because of past the gear 3 I have hasn't been on account doing the same thing as every bodys is doing logo and hard reset right back to

I had the same Rebooting problem. It Happened mid or straight after exercise or post a 2 min shower. My Wrist sweats a lot and I think the sweat would somehow get into the watch.

Even though it says Water resistant the Wefix repair man said (we recorded the telephone call) it’s just something Samsung says, but the watches aren’t water resistant AT ALL.

Took it to Wefix for repairs, they replaced the motherboard 3 times. Now I’m in comms with Samsung and the third party who sold me the watch and I’ve demanded a refund or a new watch (not the same one obviously) as it’s still within warranty.

I just had my Gear S3 Frontier stuck in boot loop and I tried the master reset method without success. I was able to fix my watch and this is how I did it:

1. Put the watch on the charging dock

2. While in the dock hold the home button until the reboot screen shows up

3. Press the home button a few times until the menu comes up and press the home button until you highlight power off

4. hold the home button to select the power off option and let the watch power off until you see the charging screen.

If not working, hold two buttons, the screen will show you resetting up still hold til the screen Samsung start as normally.

5. From here try to turn on the watch as normal, if this doesn't work try the master reset method while the watch is on the charging dock.

The Reboot, is not successful by either. Dock or not.

Regardless of watch s3 Fronteir being still new unused and sold only now in 2020 and still having 12 month warranty, I don't want to send my personal data anywhere, thus can pulling the battery out for over a decent period of time and then putting it back, can this fire up a fresh and or successful reset startup? Has any one ever done this before having to give in and send it in. 1. Has it deleted personally owned data or better yet had it started like new again?

I happen to have a jewellers screw driver set that fits the Samsung Screws

So what if any luck might I have taking the battery out, say for a long period of time, to drain any back-up power reserves remaining. And I realise that many of you are well aware of where I'm coming from. And thus trust your previous experiences and your outcomes, but am desperate for your findings.

So my S3 46mm and Galaxy Note10+5 are my combo, if this helps with your advise… Cheers

Gears3 stuck in loop won’t reboot??

I’m probably late to this but I tried resetting and even leaving it out so that it dies and in the sun for moisture. I then had an idea to pour isopropyl alcohol on it out of nowhere to clean the buttons and it worked. Lol. So before opening it up I suggest you try pouring some on it and booting it up.
