Have your standard 4-file stock firmware (BL, AP, CP, CSC) ready to flash afterward.
Look for the 5th character from the right (e.g., T590XX U3 CTD1).
Once the combination UI boots, go back to Download Mode and flash the full 4-file stock firmware to return to normal operation.
⚠️ Flashing custom or combination ROMs may void your warranty and carries a risk of permanently damaging your device. Proceed with caution.
Get the specific Combination ROM for your model ( SM-T590 for Wi-Fi or SM-T595 for LTE).
