Failed OTA upgrade

[dariosm]

After upgrading 4 sonoffs, with 5.2.1 version, just one of the would not start, keeping led light blinking for a while. I had to disassemble it from the mains (it was hooked to a ceiling lamp), and started it with a serial monitor:

ets Jan  8 2013,rst cause:1, boot mode:(3,3)

00:00:07 Wifi: Connect failed as AP cannot be reached

00:00:14 Wifi: Connect failed as AP cannot be reached
00:00:14 WPSconfig: Active for 1 minute

It seems like sonoff lost the configuration after upgrade. I should say that I followed the two step upgrade suggested in the wiki, that is, first upgrade to minimal and then normal firmware.

Is there anything I could have done wrong?
Do you think I could solved this without disconnecting from the light installation? I'm afraid next time I upgrade the modules, this could happen again.

What was the version level you upgraded from?

As you can see from the log it has defaulted the settings but started WPSconfig which allow you to press your wifi routers WPS button and your device should configure itself for your wifi lan. After that you still have to configure other parts of the device but at least you did not have to disconnect it from your installation.

@arendst sadly my router does not have that functionality (it is an ISP modem-router).
I think I've upgraded from 5.1.7, quite sure about that but not 100%. I'm certain, though, that the other sonoff modules were running the same version, and they were upgraded just fine, keeping configs and restarting with no issues.

[arendst]

Do you happen to know what the version was BEFORE 5.1.7...

From my 19 devices one of them also failed the upgrade. It just blinks the blue led every 20 seconds. I still have to look into it what went wrong there...

[dariosm]

I'm sorry for not being completely sure about this, but I think it came from 4.x version, no other 5.x version in the middle. From now I'll keep track of the version I upgrade to report more details here every time.

I found the problem in my case and will solve it in next release.

Were you using the provided release firmware or did you happen to compile your own using esp8266/arduino 2.4.0-rc1?

I downloaded from here: https://github.com/arendst/Sonoff-Tasmota/releases

Same for me, After upgrading sonoff pow from 5.2.0 to 5.2.1 version, it failed to restart.
I tried to flash it again with arduino IDE, no change.
In the serial monitor i see:

wdt reset load 0x4010f000, len 1384, room 16 tail 8 chksum 0x2d csum 0x2d v09826c6d ~ld
What to do now?

[dariosm]

I flashed it again through serial and it worked, just lost the config no big deal.

@hubecker erase flash using esptool and reload using ide.

I am having this issue as well. I am trying to upload via PlatformIO. I did change the user_config.h (perhaps the second time) but it is for sure set now with my ssid and password.

The serial monitor reflects that it is trying to connect to indebuurt1 and 2. I do see in the serial monitor that the "Project" has been changed to my setting. My version is reporting as 5.10.0a.

Any ideas on how I can correct this? THANKS! your work is awesome.
