Hi There ,
I customised the linux for wp7607 by disabling few services and compiled or built the yocto image and after flashing the new image i am getting following log in my wp7607
UBI device number 0, total 120 LEBs (30474240 bytes, 29.1 MiB), available 6 LEBs (1523712 bytes, 1.5 MiB), LEB size 253952 bytes (248.0 KiB)

Also it says kernel panic . on the other end if i try to recover the image i have following error
**swiflash -m wp76xx -i WP76xx_Release10.1_GENERIC\ (1).spk **
Detecting USB of the target
No device connected
I am able to see only one ttyUSB instead of three and with lsusb i have this
Bus 002 Device 064: ID 1199:68c0 Sierra Wireless, Inc.
It will be great if somebody helps me in recovering the image back to generic .
Thanks & Regards
