You must install TWRP in normal way before this tutorial is for restore twrp for user that used to installed TWRP before.
You can try to boot to twrp by restart device when you saw yellow text then press power+vol+
If not success, get device into download mode and install stock first.

the normal way is to install in the AP section from odin right?

You must have USB otg mouse. Cause twrp have no touch function. If not you can't finish install twrp.

i reflashed stock (the teblet is working fine)
then i flashed only the recovery for t220 tar in odin (using AP button ) the flash went well (green )
but after the reboot the tablet bootloop (it says " this tablet bootloader as been unloked ecc." press power key to continue") cant access to twrp (pressed the vol+ and power)

---

The best way , you should use my tutorial "DSU side loader to try GSI" if you not ready to install twrp.

my first time to flash twrp . (Don't use home_csc)
Howto install TWRP For SM-T225
# Patch Samsung AP Firmware via Magisk v24.0
1. Install Magisk.apk on your device SM-T225 with select no update checking, and transferred AP_xxx.tar.md5 from computer to your tab.
2. Patch Samsung AP Firmware via Magisk Manager.
( Once done, the newly created magisk_patched.tar file will be present under the
Downloads folder on your device.)
3. you may now transfer this patched TAR file to the folder on your PC where other extracted firmware files (AP, BL, CP, CSC, and HOME_CSC) are present.
4. FLASH it with ODin as usual by used magisk_patched.tar file at AP slot .
5. REBOOT SYSTEM Quick SETUP < NO NEED INTERNET>
6. Power Off and press Volum up +Volumn down + USB for boot into Download mode
7. FLASH TWRP.tar from https://github.com/DevZillion/android_device_samsung_gta7lite/releases at "AP slot"
But this time set Odin option NO Auto- REBOOT, yes do it yourself with key press ( power + volumn up). If you can't do this , let it reboot to system and uses cmd " adb reboot recovery".
When access to twrp
Go to Advanced > Terminal and type "multidisabler" (without quotes", then data wipe.
Now reboot into system, after completing first setup of the device reboot into TWRP again to see if you can see the contents of your Internal Storage, you should, if yes you have successfully disabled Samsung encryption of internal storage.
