Update fail 11... SIP-T20P - josemiguel891988 - 09-17-2013 10:12 PM
Hi everybody
I need help. I have one phone SIP-T20P, it's broke the firmware.
looking in the website i found an recovery mode update for Yealink via TFTP. (t38.rom and t38.bin) rename both file to t20.rom and t20.bin and the make root directory (C:\tftp).
After filling the right value (IP, Masck, getway and TFTP Server) for the phone for download the firmware and update.
after minutes, show on the LCD: …Update fail 11… Please reboot (#define WEB_UPD_PROT_VER_ERR 11 /* the protocol version is faulty).
As i can make work the phone again?

Hi Jose,
I am afraid this phone was broken, please contact your distributor/reseller to deal with it.
Thanks.
