| Hello.
Your phone has firmware with new type of Security. To restore the phone to initial condition - write "Security-SM-G925T-Unknown24-02-2017_18-07-06-.asec" Security backup backup into the phone.
To process the phone You can try to write older (by release date) firmware, or only its modem via "Advanced Mode" of "Write Firmware" operation.
Also You can use new "Repair IMEI" solution. |
