Completely bricked? SOLVED, but incredibly frustrating

So, since I wasn't able to upload from the original .219 firmware through the Firmware Update app on the /apps page, I thought I'd try the Web IDE flasher method.

I'm now stuck an a screen with:

SW RESET
DFU 2V10.219
CHECK STORAGE
NO NEW FW
BANK0 INVALID
BTN1 = REBOOT

And nothing will get me past that.

Additionally, when selecting the Bangle.js 2 board in the Web IDE Flasher - Flash Firmware page, I get the error:

Sorry, the firmware update has failed.
The error was: Unable to download https://www.espruino.com/binaries/espruino_2v10_banglejs2.zip
Please try again, or check out the Troubleshooting page for what to do next.

I had also tried downloading the zip and then going the Flash from File route, but I got another error about being unable to read the zip and then the watch showed a CONNECT ERROR.

Could someone please give me step by step instructions?

Update: I followed the nRF Toolbox method here: http://www.espruino.com/Bangle.js#firmware-updates

It worked - kind of. The watch disconnected after every 1-2% of progress, with 0 bytes reported as received. After clicking on Retry, 50+ times, it finally got as far as 100% and then seems to have booted to 2V10.244 (according to About on the watch).

Surely it's not supposed to be this difficult/complex/frustrating? For anyone who is not in any way tech savvy, this kind of thing would be a deal breaker I would think.

I enabled the app loader firmware update on Friday - it was supposed to make this process a lot easier! I'll try and get a fix in for that today though.

What device did you use nRF Toolbox from? When I do updates here from an Android phone it just sits there and flashes in one go.

Hi Gordon,

nRF Toolbox did the trick (with the .zip file) on iPhone 11 Pro Max, iOS 15.1. It worked eventually, but it wasn't a simple one-click operation, as I've written in other comments.

Other than that, this is a great successor to the Pebble, and arrived just as my Pebble battery decided it couldn't cope any more!

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

> Quote text by starting lines with >

Mention another user by @username

For syntax highlighting, surround the code block with three backticks:

```
Your code goes here
```
Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
