xperia s not booting into recovery

Hi, I just installed the latest Paranoid Android ROM into my Xperia S.. During the unlock of the boot loader the device was recognized by my PC in fastboot mode, so I had no problem unlocking it. Not even flashing the recovery (TWRP) and the boot.img file gave me any problem..
Now if I try in any way to boot into recovery, my phone gets into fastboot mode instead of recovery mode. Also, my PC can't recognize the device anymore.. If I connect the phone in fastboot mode into the PC, the PC says that there are no driver installed.
If anyone could help me, it would be really appreciated..

G4 bricked after trying to instal SU - Help

Hi guys!
I really need your help. Few days ago i had installed Cm 14.1 and everything was fine (i had unlocked the bootloader, installed TWRP, rooted the phone) yesterday night i wanted to install SU so i downloaded the .zip, logged in recovery ..and by choosing "install" i flashed the zip ..but after the restart from twrp the cell didnt work anymore , the little cm alien face is always loading. I tried to to get in bootloader mode by pressing the power button and volume down then relasing it and pressing it again but nothing happens. I got in download mode , connected the phone to the pc (after having installed the drivers) but i always get the message "waiting for device" when i try to get into recovery (bootloader recovery command ..well just because bootloader devices doesnt show me any phone connected) . So actually i dunno how to get in bootloader mode and make windows to see it. Any help would be really appreciated.
i add that i worked on a recovery loaded with fastboot command from windows so i didnt really installed it on the g4 even if i copied the img file on the sd card. Therefore i need to get into bootloader mode in order to send fastboot commands again
Thnx

When I reboot into recovery TWRP gets stuck in a splash screen loop.

Hello, ever since I flashed the 14.1 nightly CM ROM, TWRP has no longer worked. I have tried reflashing the compatible MM BL and also tried a normal TWRP using fastboot, and nothing seems to fix it. Whenever I reboot into recovery mode, it just flashes a gray screen and never gets out of the loop. My phone can start up into normal mode fine, its just recovery that does not work.

download above files and extract files. go to MM bootloader folder. now reboot your phone into fastboot mode and connect to PC. now run upgrade.bat... once it finishes transfer file. and phone reboots the bootloader. now run twrp.bat. now as transfer finishes. now very important do not boot your phone to normal os.. find option for recovery mode and reboot into recovery. you will get into recovery..

No ROM, No Recovery, No Fastboot or HBOOT ! Help Please

So basically what happened is that i flash a bad rom on my htc a5dwg. I could boot into TWRP 2.8.7.0 and flashed roms through ADB sideload but all gave me some error and were not flashing. So i flashed TWRP 3.1.1 img. Now i cant Access recovery, nor power and vol down button take me to HBOOT or Fastboot mode. Cant reboot to rom. Stuck at boot screen with HTC logo and the unlocked bootloader warning. I connected my phone to laptop and it does show up in device manager as MTP USB device but i cant use fastboot or ADB commands as it does not show up in the Fastboot ADB device options, Some help would be highly appreciated.
