Further, if I get any parts wrong, PM me and I'll get those parts corrected.
Android Partition, SPL etc.
Followings are a list of partitions on your ASUS Transformer Prime (TF201).
misc - misc partition -
recovery - Recovery Partition - This is where the original CWM recovery or any other Recovery would go. Basically if you reboot into recovery it'll boot from here.
boot - This is your boot partition also known has kernel
system - This is where all your system information (ROM resides)
cache - cache (When you factory reset the phone, this area is wiped)
userdata - user data (like your login, your user settings etc) When you factory reset the tablet, this area is wiped)
So, if you replace the recovery image, you are pretty much set for updates provided here at XDA.
ROM images will normally replace boot and system images at the same time and often time, userdata and cache too; reseting the phone completely.
SPL / Bootloader is like BIOS on a computer. At least I think of it that way. SPL can be updated! SPL comes as either Security-On of Security-Off (S-ON/S-OFF).
How do I know the tablet is bricked? A bricked tablet can not boot into bootloader, recovery, or into normal operation modes. You can not connect to a bricked tablet via adb or fastboot. You can only see one screen on the tablet and it will be the first splash screen.
