USB Upgrade issues
Hi, I am trying to recover a couple of T58 SIP phones and I have the BIN, RFS, and ROM files on USB. I boot the phone with the USB installed in the back while pressing the speaker button and I get Usb failed (-4)

Is it looking for a specific format of USB stick? I am currently formatted FAT32

Also tried renaming the files T58, T58A, T58V but nothing seems to help.

Any ideas?
