Hi, I cannot download the FW success. My step is below: Failed steps: 1. update to R16 generic image. 2. modify some init file in yocto source then compile. 3. update to custom image. (This time will be success) 4. modify some init file in yocto source then compile. 5. update to custom image. (This time will be failed) I always can update success when I update to R12 and do reset then update to original R16 and update custom R16 image. So I want to know where R17 is supported reset command? ---

what reset command do you mean? Here says you cannot downgrade after upgrading to R17: [https://source.sierrawireless.com/resources/airprime/software/wp76xx/wp76xx-firmware-release-17/#sthash.9jSgC307.dpbs](https://source.sierrawireless.com/resources/airprime/software/wp76xx/wp76xx-firmware-release-17/#sthash.9jSgC307.dpbs) ---

starting from R13, you cannot run that, you need to delete the userapp partition manually e.g. > [@Swiflash -r broken with release 12 on wp77xx?](https://forum.sierrawireless.com/t/swiflash-r-broken-with-release-12-on-wp77xx/20957/2): > > According to the release note of fw r12, QTI9X07-2870 is to fix userapp partition being erased which is security hole. You might also try the following without downgrading to older version: (Be careful of the mtd number, different FW might have different mtd number for userapp partition !!! ) root@swi-mdm9x28-wp:~# cat /proc/mtd|grep userapp -i mtd16: 08300000 00040000 "userapp" root@swi-mdm9x28-wp:~# pwd /home/root root@swi-mdm9x28-wp:~# ls UART\_Test1.wp77xx.update root@swi-mdm9x28-wp:~# fl… ---
