i think you manualy need to flash it, not use the cloud update until you flash the last firmware version

Blue LED Blinking Continuous after AT+CIUPDATE

2015-03-27T15:44:01+08:00

The modules which I received recently had firmware version 0.9.4 & communication worked on 9600 Baudrate.
I issued AT+CIUPDATE\r\n command ... post that I'm not able to communicate with the module serially ... it is continuously emitting garbage data & the Blue LED on module blinks fast ...
I even tried Reset via RST pin ... but no luck .. after reboot the module goes on the same state ..
AT+RST / RESTORE also does not work

Is the module bricked ?

Kindly guide

Thanks
