Hi,

I flashed R12 into my WP7607 several times, but after reboot, I get a ‘fw version mismatch’.

I got some target info using the commands below  
_AT!GSTATUS?_

- AT!PCINFO?\*
- AT!IMPREF?\*

How can there be a firmware version mismatch after I flash a complete R12 firmware release?

Apparently the modem stays in Low Power Mode.

I tried the WP76xx\_Release12\_GENERIC\_GCF.exe (downloaded on following link) on WP7607, no problem is found.

Hi,

I always use Developer Studio on my Linux host to flash R12 (Flash Firmware from external file).  
After reboot, I got ‘fw version mismatch’.  
Several retries didn’t fix the issue.

Now, I tried to flash the target with the R12 Windows one-click executable, and after reboot the issue was fixed 🙂
