Flash brushMandatory:
In terms of differences between version 9300, you can use the I9308 and I939 I9300 ROM to brush the I9300 ROM.
Before flashing, make sure to back up EFS to prevent the baseband from being unknown. Of course, you can also back up the EFS after refreshing it. The probability of the baseband being unknown is very small.
There is a risk of flash brush, please be sure to make sure your mobile phone power is above 15% the best, please do not perform any operation during the flash brush process, so as to avoid changing bricks.
Before you click it, be sure to identify whether your mobile phone is 9300 or 9308/I939. (too many people have mixed up and then become bricks)
