Hi,,,i am using samsung galaxy j6 infinity 2018 model. But Unfortunetly Im Flash The Singapore (XSP) Region Firmware,,,& Now Jio VoLTE Service Not Working On My Device. im try to go back on my Previous android version,,,Which is Pie..but when i try to flash The Firmware Via Odin..It Says SW REV CHECK FAIL DEVICE 7, BINARY 6. The Singapore Region developers Updated The Bootloader from U6 to U7. & India Release The Android 10 Firmware,,Which Comes With Old U6 bootloader. i am not able to do anything until indian developers releases next software update which comes with U7 or Upper Version Bootloader.
FIRMWARE INSTALLED ON MY DEVICE CURRENTLY : J600GDXU7CTF1 (Android 10)
INDIA (INS) FIRMWARE IS : J600GDXU6CTF4 (Android 10)
I Actually don't know that once the device bootloader is upgraded...its impossible to downgrade.
(DUE TO SAMSUNG SECURITY POLICY)
If anyone know some solution please suggest me into the Comment Box. I need help.
