2.80 fw update failing

[badgerwithagun]

Hi, just got my WICAN and trying to update to the latest firmware. Mine arrived with v1.69.

I tried upgrading to v2.80 OTA, but this just caused the device to reset to factory settings without changing the version number.

Not wanting to go straight to the USB option, I tried upgrading to v1.71 OTA. That worked fine. I then carried on all the way up to v2.50 OTA with no problems. None of these upgrades caused a factory reset.

Then I tried the upgrade from v2.50 to v2.80 and got the same problem as originally. The upgrade seemed to work OK, but the device was reset to factory settings and it still shows v2.50.

Any suggestions (other than the USB option - I want to avoid it if I can, since the car isn't nearby)!

@badgerwithagun I'm aware that there's an issue with the OTA, I'm still trying to find a solution. Please see the comment below.

Thanks @meatpiHQ

@badgerwithagun Please try v2.90. After the OTA is complete the page will refresh and goes back to status page, you'll need to refresh again and check the about page if it was successful.

@brainstorm wow! Never seen anything like this before. There's no v1.00. Which browser are you using?

[brainstorm]

Hey, sorry for deleting the post, I'm using firefox with uBlock Lite (AdBlocker) and after you mentioned that I disabled it and it now shows 2.90 and a different Hardware ver!:

Anyway, reposting it here since I thought I was doing sth wrong because I didn't short the two vias you show in the docs, but same result... although now we know it was a browser issue (sorry to hijack this issue I'll now try OTA updates and report back when there's a newer version)!:

@meatpiHQ This updated failed for me over cable as well anyway (tried OTA and didn't work either) 🤷🏻

I apparently have a v1.00 WiCAN dongle and I was trying to update to wican-fw_v290_hv300.bin (I saw it on https://github.com/meatpiHQ/wican-fw/issues/77#issuecomment-1812614826) via USB port instead of OTA:

Seems like it went alright:

The example Readme.txt is quite wrong in a few ways and doesn't work with today's esptool syntax nor firmware paths, btw:

esptool.py esp32c3 -p COMx -b 460800 --before=default_reset --after=hard_reset --no-stub write_flash --flash_mode dio --flash_freq 80m --flash_size 4MB 0x0 bootloader/bootloader.bin 0x10000 wican-fw_vxxx_hv300.bin 0x8000 partition_table/partition-table.bin 0xd000 ota_data_initial.bin

But when re-connecting to the dongle, it still states 1.00?:

@meatpiHQ - 2.90 upgrade worked fine OTA 👍🏻. Thanks.

I'll leave this open for @brainstorm
