Reboot loop on Kospet Hope

I had thought compared to some of the other problems I had read on here, I was lucky.
Have worn my Kospet Hope as my only watch AND my only phone for more than a week with almost new issues, just the standard workarounds.
Stock firmware 20190320 from the factory.

But now it just entered a reboot loop that shows the Kospet screen and then goes black, over and over again. On the charger it displays the same behavior.

I read in the other manufacturer categories that I might have to flash but NOOOOO! I’m hoping it’s not the same with Kospet… The flash tool didn’t even work when I followed the directions precisely and tried to install latest firmware on this Windows 10 machine when I first got the watch, so I stayed with the 20190320 version at that point. Is there a button combination I can use instead to get out of this loop?

Eventually it stopped rebooting, after a very long time of the same cycle, I’d say 1.5 hours. At that point it just booted one last time as normal.
I think it might be a problem with the battery, OR the firmware thinks it’s a battery problem and initiates a low-power or battery overheat shutdown. Because right after it finally booted correctly, it said 80% charge, now it immediately says 2% charge within about 2 minutes.

Yes, if the battery is very low, the system tries to boot but has not enough power. So it fails, turn off and tries again. This stupid behavior is present on some watches…
With a good charger, it can ease the watch to boot and reduce that behavior, with only a low power charger 0,5A, it can take some tries…


Unfortunately the watch appears to be bricked now.
It entered another reboot loop today. Eventually it showed a weird bios screen that said something about booting to normal mode or something else but it was automatically scrolling through options on its own so fast that I couldn’t read it.
Then it just turned off with a black screen forever.
Charging doesn’t seem to do anything. Button presses don’t do anything. Plugging the data cable into my computer also does nothing, completely unrecognized.

I reached out to the online store where I bought it to see how to get a replacement…unless anyone has other ideas.

I have just now happened to me this boot loop. It didn’t stop until the battery died and charging it still the same. looping from black screen to battery icon charging. Do you guys have any solutions? It will be much appreciated. Thanks!

Flashing should work ? Maybe worth explaining what went wrong . I also had the bios screen thing happen to me on a H2 . Exact same behaviour years ago . Funny thing was i pressed and hold both buttons tightly for a minute , screen died and went black . I gave up and left watch . A hour later watch was back on ?

Everyday after work i would turn off kospet after i reached home of course. Seeing It was around 54% of battery life i was thinking not to charge it and (since i can still use it the next day) set it aside turned off. Then as i was trying to press the power button (btw, i noticed i’m having hard time recently with the power button not responding properly) to turn it off like i usually do for the past months and that loop happened.

I took the matter to my own hands and I think I may have found the problem causing such loop atleast on my Kospet Hope. Will test it more before I share it with you guys that may have experiencing with same issue.

I am interested in knowing what your theory is about this.
My own theory is that bad quality components make it through quality control testing.
It has always been a problem when so many hundreds of watches are produced and quality control is not very good.

You are correct pablo11. A very bad quality component causes my boot loop issue.
So I decided to take my kospet hope apart to isolate what was causing it. Is it a hardware issue or a software? (please do it at your own risk if you decided to take apart yours. I will not be held liable if anything goes more wrong about your smartwatch. Just here to share.)

The image below, one with the arrow pointing to the momentary switch which is the power button is the issue i found causing my smartwatch to boot loop. The momentary switch was loose and corroded.

The solution i made in order for the watch to function and usable again was to fiddle with the momentary power switch until it worked and didn’t boot loop. Notice the above image where the switch with red arrow(lower button/back button) and with the yellow arrow(upper/power button). I did rotate the orientation of the switch and position it until it was not loop booting since a switch’s work is to short/complete a circuit and open/break it. But i cleaned first the contacts before I did all the positioning which was pretty strenuous attempt every time.
Anyways the tactile feeling of the power switch will no longer be there but hey it will be now working.

I do hope KOSPET will do more quality hardware parts and inspection since most people will not bother attempting on opening their watches. Thanks!

Also thanks for the watch faces you guys put on here! Love and Respect to all of you!


You are amazing xcvi96, to take every component apart to prove that. I took my own Hope apart to a lesser degree when it was having the reboot loop but it’s HELL to put back together correctly so you are a hero.
I completely agree, I’ve got three total watches from Kospet & Zeblaze & Lokmat with bad power buttons where they have to be pressed very hard or at a certain angle or no longer work at all, and short of a complete tear-down and rebuild like you did, it’s such a waste of a good concept for a watch. (And I own exactly one of these watches where the power button is intact and works every time.)
