@Gordon, thanks. You were completely correct. It's working now.

Hi.

I installed the Red Torch app on my Bangle.js (original), and got the "Hold BTN3 to reload" message. BTN3 did nothing. Neither did 1+3 return me to the clock.

Neither does using 1+2 to restart, nor 1+2 and release 2 for a no-software restart. They display these messages:

WATCHDOG
DFV ZV05

Then a new screen:

Bangle (JS in a watch logo)
2V09.79
e6:ba:3e:fe:95:1e

The only thing it will respond to on that screen is the 1+2 forced reset. I'm about to use that to turn the thing off to save battery.

I can connect using Bluetooth. I removed Red Torch. The Bangle displayed the same "Hold BTN3" message, and again holding BTN3 did nothing. Now "My Apps" in the web interface shows nothing. I promise I had apps installed.

I followed the instructions here: https://www.espruino.com/Bangle.js#resetting-without-loading-any-code, installing default apps. This worked, and the system inexplicably installed my default apps. Aaaand ... BTN2 does nothing, I can't get to Setup or anything. And 1+3 ... makes the time jump ahead 5 hours, from correct to 5 hours fast?

I tried installing a different launcher (the Desktop Launcher) but this did nothing.

I know you'll say to install the latest firmware, so I downloaded it to my Android phone. The procedure (https://www.espruino.com/Bangle.js#firmware-updates) says to upload to a device named DfuTarg. There isn't one. Attempting to upload to the Bangle device (which is listed) results in the message, "Upload failed: DFU CHARACTERISTICS NOT FOUND".

How to proceed?

I could easily be remembering the time wrong. I updated the firmware the last time I wrote to whine, er, ask a question, so months ago but not the original.

Hi, Gordon,

I did turn it off using the Setting menu.

Also, it isn't your fault. Turns out it was the old cable from the previous watch that failed. The cable that worked has the little "direction of the charger" tag on it with a Bangle picture. Sorry about the mistake.

... also maybe a month of disuse shouldn't cause a turned off watch to have zero charge?

What with not leaving my house much for some reason, I hadn't turned on my Bangle for a while, probably over 3 weeks. When I tried yesterday, it was dead. I tried button 1, then 1+2, then every combination I could think of for 10 seconds at a time. Nothing.

I charged it for a couple of hours and tried again. Nothing still. That is, I magnetically adhered the cable that came with the watch, which was plugged into a voltage source.

I was literally in the middle of posting this message when my years of experience with USB cables kicked in and I had to revise. USB cables fail. So I found the charging cable from an old smartwatch, which happened to be identical to the Bangle cable, plugged that in, and the watch started immediately. It had run down to zero power during the long disuse, and coincidentally the Espruino-supplied charging cable had failed. Luckily, another cable I had lying around coincidentally could be a substitute.

So, this message went from "request for help" to "maybe you need higher-quality cabling," I guess.

Thanks again, Gordon. That "runs automatically" aspect isn't clear, at least to me, from the description. Appreciate your taking the time.

I tried to install default apps. I got "App install failed". The second time I tried, it seemingly worked.

App loading appears to be working normally now. Thanks!

@Gordon, thanks. I did not realize that a widget never appears in the ap list on the Bangle ... which then raises the question of how to remove it, aside from a total reset as you advised above. I'll be trying that now.

GPS Auto Time said it was installed, but as I wrote above, it never actually appeared in the app list.

Hi. I got my Bangle some time ago, but what with the quarantine have rarely worn it for months. (I tend to only wear a watch when leaving my home, which I'm not doing very often.)

Today I did wear the Bangle. I noticed that after I wore it for about 30 minutes, the time/date reverted to 20:00 December 31 1969. (The watch has never had its battery drop to zero, FTR.)

I reset the time, and wore it all day with no problem. When I got back, I decided to install a couple of apps, because I don't like the morphing clock and the insanely-tiny-type pedometer. I made it discoverable, paired my phone, loaded the Bangle.js app loader page in Chrome on my Android phone, and tried to install the "Large Clock" app. The watch froze solid, the time stopped advancing and it didn't respond to anything short of the two-button reset. That restarted it ... thinking it was December 31 of 1969 again. I see that's expected behavior after a hard reset, but that does raise the question of why it did that spontaneously.

I was then able to install Active Pedometer, but the atempt to install GPS Auto Time failed with the terribly useful message: "Upload failed. Unexpected response."

Installing GPS Auto Time to fix the time travel problem required six attempts, and only worked after I turned on debug info. (I don't know if that was just a coincidence, of course.) However, despite the app loader claiming it was installed, GPS Auto Time is not in evidence and the time remains committed to the past.

I then updated to the 2.6 firmware. I still can't install GPS Time.

Clues? Hints? Suggestions? All are welcome. Questions are also welcome, if I can help debug this. Thank you.
