Hi ,if you had upgrade the new version 2.3.1 for your UC300 ?
But after reboot ,the web page can't visite and can ping the default IP 172.16.101.1 ？

Pls try press the RST button about 10 sec . to reset the device ,then try visit the device web again .

hi,my verion is 2.3.1 -device is UC500 -
this is my steps :
1-i write Issabel4.0 by rufus on flash USB
2-turn off device and connect flash USB
3-turn on device and heard BEEP
i can ping 172.16.101.1 , but i cant see wep page on this IP

pls read the manual more careful ！！！
First,you must write Fedora22 by rufus on flash USB-disk .
Secord ,connect USB-disk on UC and power on device .the device will upon with Fedora22 .
The Fedora22 default IP is 172.16.101.1 username: root pswd:111111
And if your USB-disk size is 32GB or more ,pls do disk mount follow the manual step 4 .
If your USB-disk size less than 32GB ,pls read the step on the tag end of manual
You need to do windows shared folders mount to Fedora22 for upload the Issabel4 file .
Notice :before do the flash you need change the Issabel4 file name as backup.img !
