Really strange…
This morning my LES1 hanged up on the app drawer and turned off itself.
No more alive… Power button, long, short, several times. Nothing. Dead.
I’m trying now to reflash it using, as usual SP Flash Tool. No way: ERROR S_FT_GET_MEMORY_FAIL (4058) - Cannot Find Memory
if sp flash tool still see it then it is’nt dead have you tried with newer sp f.tool? and use upgrade?
Tried with SP Flash Tool 5.15 / 5.16 / 5.17 and latest 5.18.
Everything fails, upgrade, download, format and even memory test
Same error, always…
Other attempts, no way. Now no errors come out from SP Flash Tool. It simply waits to connect to something. And waits… and waits…

Yes, 3 different usb cables. Same result, SP waits forever

I noticed that nothing happens in Device Management of Windows connecting LES1…
EDIT : ok, done. No need to disassemble it, just removed the back cover and remove the black connector of the battery. Nothing happens, not turning on. Now ?

It could be the latest idea but how to dismantle it securelyI noticed that nothing happens in Device Management of Windows connecting LES1…

Has anyone considered that the battery is dead or defective? Doesn’t the watch have to be able to power on to flash it? All the conditions he mentioned initially, shown above, would indicate to me that the watch has no power.

Yes it could be but how to be sure ?! I don’t think to buy a new battery for the LES1, if the problem is not the battery I’ve just wasted time & money.
There’s a way to check it ?
if you have access to a multimeter, check and see if there’s any juice left in the battery, sometimes with really tiny connections i’ve had luck tying stripped down bread ties around the prongs on the multimeter if they are too big. i recently had to pull the battery on my watch, it seem like it might be kind of easy to mess up the terminals, so if you’ve pulled the battery in the past, it might be something to consider
fyi, cannot test from the terminals on the outside of the watch

Yep, I’ve 2 multimeters I’ll try ! Thx
EDIT : checked, I’ve seen 2,90 - 2,91 V
i’m having trouble finding exact specs on the battery for these, if i had to guess, it should probably be in the neighborhood of 3.7v (if fully charged, just guessing) and if that’s the case i’d say it’s probably critically low. i’ve had some success reviving depleted batteries in the past by placing on charge for a few minutes, pull off charge, wait just a few seconds(like 2 seconds), put back on charge for a few minutes again and repeat. can take quite a while, especially if very dead. i think it works because the amperage is higher that split second when plugging in and it seems like that surge is what pushes it over the threshold of being able to power on or at least start to show signs of life. sometimes after reviving a dead battery they don’t fully recover i.e. shorter life but either way you’ll know if thats the problem. if i’m wrong on what the voltage should be or maybe it’s another issue, at times i’ve had success by completely removing power(battery), then hold the power button a second or two, then plug in the battery in while still holding the power button. good luck, be patient with it if it’s depleted, maybe use higher amp wall plug if you have one
side note: reviving the depleted battery: since it’s kind of a drawn out process, i’d be more inclined to just have it on a charger near by so you’ll remember to do it periodically, if my theory is correct it’s more dependent on the whole plugging and unplugging but be sure to leave it connected at least a few minutes in between
Well, 2 off topic updates :
Only charging, USB connection with my notebooks not working. But using old Lemfo Les1 USB dock, everything is working fine… Bad cable… I’m always lucky !

thanks for speaking up, just taking a wild guess, either way that battery would be considered dead
Tomorrow I’ll ship it to Gearbest warranty service and I presume… I’ll never see back my watch
