How do you downgrade the firmware on a 5410 handset from R5.0 to R2.0?
Is it just a simple case of connecting it to a system running on pre 4.1 software with a TFTP server & the correct bin file available?
I have a client who has connected a 5410 handset with R5 firmware to a IP406 on software 3.1(65) with manager open and the working directory pointing to the corrct folder which has the 5410_R2.bin file but after a few minutes of the handset displaying "Please wait" the entire DS16 expansion module resets and no firmware gets loaded. Any ideas?
