thank you guys, I appreciated... yes, I know all these possible ways in.. but the point is that enable_adb does not work for me.. I suppose the RSA key on my device bootloader is different so the PRS T1 Updater.package is not booting anymore

... this is just a "suppose" ... in reality, the enable_adb package is so cool because it flashes a new ramdisk... which is cool, with usbdongle enabled but very dangerous because it flashes a new bootloader too. I am scared to brick my device, so I would like to get a dev/block dump before to start flashing other stuff on it ... thinking to disassemble or .. uhmm I don't know...
