Tutorial to install stock rom / firmware on galaxy A30s SM-A307GT
Using Odin, follow these steps below.
Attention, there are 2 installation modes, with 4 and/or 5 files, or
installation with 1 file.
obs: for firmware with only 1 file, follow the same process, add only in AP/PDA
Installation for roms with 5 files via Odin
To Download current Odin or previous versions compatible with your device< Aqui >>
Extract the firmware you just downloaded. You should get 5 files:
1- AP (System & Recovery)
two- BL (Bootloader)
3- CP (Modem / Radio)
4- CSC _ *** (Country / Region / Operator)
5- HOME_CSC _ *** (Country / Region / Operator)
Add each file to its respective field in Odin vx.xx.x.
use CSC _ *** if you want to make a clean flash or
HOME_CSC _ *** if you want to keep your apps and data.
Restart your phone in Download / Odin mode with the following button combination:
POWER + VOLUME DOWN + BIXBY
Other options if the first option does not work or is not possible.
VOLUME DOWN + VOLUME UP, plug in USB cable
POWER + VOLUME DOWN + VOLUME UP
POWER + VOLUME DOWN + HOME BUTTON (this is the most common)
Once in download mode, connect your phone to the PC, preferably using the original USB cable.
Odin should detect your device and a BLUE box will appear with the COM port number.
(Make sure SAMSUNG DRIVERS are installed on your PC)
DO NOT check any extra boxes. The only options to be checked are F.Reset Time and Auto-Reboot.
Click the start button, wait for Odin to say ‘PASS’ in a GREEN box. When the flash is complete, the phone will reboot and you can disconnect the phone from the PC.
* The first boot (initialization) may take a few minutes, don’t do anything, just wait.
