So I reset my Galaxy S3 to factory settings through recovery mode but then noticed that it wouldn't boot any longer until the Samsung splash screen. I tried looking online for solutions and tried flashing a Stock ROM through Odin but it always failed everytime. Now I get an error saying "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again". It also says I'm in Odin Mode on the top left along with the following information:
PRODUCT NAME: SGH-I747M
CUSTOM BINARY DOWNLOAD: No
CURRENT BINARY: Samsung Official
SYSTEM STATUS:: Official
DUALCOM SECUREBOOT: ENABLE
Warranty Bit: 0
BOOTLOADER AP SWAREV: 1
Kies also can't read the device. What should I do?
