In the end, I just used a previous version of Odin (3.4 instead of 3.9) to flash an original stock rom.

Now the problem is that I have a new CWM that works with the volume up, volume down button, and this menu:
- reboot system now
- apply update from ADB
- apply update from external storage
- zipe data/factory reset
- wipe cache partition
- apply update from cache

Since the rom is not really good, i wanted to flash another one , but the backup i did with the previous CWM i had (Philz Advanced CWM 6.08.90) is nowhere in the tablet anymore (i dont have any sd card) and i dont know how to make a back up with this CWM...

So now the question is how to make a backup with this version of CWM so I can try to flash other roms, or how to get the version that i had before without takin any risk of brickin the device (so i can make another backup and try to flash another)?
