v7.2.0: No Web Setup or serial communication

[jeroenrnl]

PROBLEM DESCRIPTION

I've flashed a couple of new Shellys (Shelly1 v3 + Shelly2.5) with v7.2.0 but it didn't show an AP to connect to and on the serial terminal I see only this:
00:00:00 WIF: Connecting to AP1 in mode 11N as tasmota-7798... 00:00:16 WIF: Connect failed with AP timeout 00:00:16 WIF: Connecting to AP2 in mode 11N as tasmota-7798... 00:00:32 WIF: Connect failed with AP timeout 00:00:34 WIF: Connecting to AP2 in mode 11N as tasmota-7798...
Typing on the serial terminal doesn't do anything.

I've downgraded to 7.1.2 and that works flawless

Hi, first time user here. Just "bricked" two sonoff minis myself. seems to be same problem. The blue LED of the mini is just blinking maybe 500ms off 500ms on. Flashed with Sonoff DIY OTA.

Edit:
Sry for the confusion. My devices are probably still working and can be flashed over serial. It will just take some time for me to do, because as a beginner the OTA functionality is way more easy.

Mine weren't bricked, simply reflashing them with other software fixed it, at least for one, reflashing the others now, but I'm quite convinced they will be fine too.

Verified. Will release updated files.

I reflashed one with the updated release and confirm: issue fixed. Thanks for the amazing service (40 minutes from bug report to fix!!!)
