Im having an issue upgrading the firmware on both a GXP 2160 and 2140. On both phones i managed to upgrade the boot version, but the core, base, and prog all stayed the same as did the GUI. I use a TFTP server and have tried many firmware versions both old and new using archives from softpedia, but I have been unable to get the phone to recognize them. On the TFTP side it shows the phone establishing communication but it shows transmission failed couldn’t find file cfg.xml, cfg000b826715ef.xml, ring1-3.bin, etc. I’ve had luck upgrading other phones with this TFTP Server, even another 2160.
I have also tried the Grandstream HTTP link for 126.96.36.199 with no luck.
The GXP2160 Shows:
The GXP 2140 Shows:
Any suggestions on how i can get these up to the latest firmware?
