Firmware has bad image tail

Hi all,

I'm trying to pull the current AP out of unleashed to a solo image. It worked for (4) AP's yesterday, but now it's not working on other AP's for some odd reason. I have an H510 trying to push FW: 118.2.0.0.875.bl7 on my AP.

This is the error i'm getting:

rkscli: fw update fw: Updating rcks_wlan.bkup ... v54_fw_update: download 192.168.5.1 section=rcks_fw.main image=Image2 ctl_file=1 18.2.0.0.875.bl7 (/writable/fw/main.cntl) local=0 NET_CLOSE() rc1=255 rks_fw_update.c:4105 v54_check_fw() Control file Parse Error (applicable for con troller upgrade only) net_get_flash_ubi(192.168.5.1, 118.2.0.0.875.bl7, rcks_wlan.bkup,, 0) flash id is 0 imghdr.{hdr_len=160, bin_len=13978557} fw_flash_read_open: kernel open(/dev/ubi0_0) rootfs open(/dev/ubi0_1) fw_flash_read_open: kernel open(/dev/ubi1_0) rootfs open(/dev/ubi1_1) flash id is 0 Image2 FW check ...

Again, this worked on (4) AP's previously, but now it's not working on the (2) that I've tried.

Any ideas what's going on? The last resort is to go to each AP to factory reset it, but I'm trying to avoid that If I can.

thanks!

UPDATE: I tried pushing this upgrade again and am now getting this:
