Apps2SD has nothing to do with recovery. It does not have proper "OS Firmware" in it. You probably meant my backup/rescue package. Using HOME+MENU could be tricky at times - requires proper timing. IMHO the easiest way is "ebook_msc.exe name "PRS-T1" um recovery". Test mode is an app which is always installed (by Sony) and it allows reboot in recovery mode - doing analog of "chgboot recovery && reboot". If you have a rooted device and are using ADW Launcher - you would know what to do

All devices have Linux recovery kernel image on them and all are capable of entering this mode out of the box (device do not have to be rooted). It is what happens next - as jarsto explained. Not only you should have proper image (on SD or in internal memory) which allows you to open terminal connection to the device, this image must be of a proper version and your computer must be capable of recognizing USB serial gadget (not a problem under Linux, requires installation of proper INF file under Windows).

All of that has nothing to do with ADB - which indeed need to be installed on the device by using Apps2SD (or some other way) but is not required to connect to device in recovery mode. Recovery mode is not debug mode - it is entirely different. Different kernel is booted and regular system and /data partitions are not mounted allowing device firmware to be recovered or upgraded.
