As i understand full factory reset should be done by pressing reset button, if yes then it doesn’t help. i can see wifi network but i can’t connect to it, it says wrong password. these gateways are new , i guess they were dedicated to specific network server but never used and never will be.
From serial port i’m getting :
ets Jan 8 2013,rst cause:1, boot mode:(3,7)
load 0x40100000, len 2592, room 16
load 0x3ffe8000, len 764, room 8
load 0x3ffe82fc, len 676, room 4
2nd boot version : 1.7(5d6f877)
SPI Speed : 40MHz
SPI Mode : DOUT
SPI Flash Size & Map: 32Mbit(1024KB+1024KB)
jump to run user1 @ 1000
and after this line only trash comes from it. that why i think firmware is not stock , it might be corrupted but according led device starts and jumps into wifi configuration mode.
