Firmwareupdate loop GPX1625


we have some GPX 1625 with Firmware Version, last Week we do upload the new Firmware Update on the UCM to deploy at all GPX Phones works fine. Two GXP1625 has Firmware Version and going into a loop and make not the Update. Factory Reset, DHCP opt., 3CX, don’t helps.
Thanks for reply.
