Previously, I have published the simple instructions for unlocking bootloader in Samsung Galaxy A03 SM-A035F. Now, I will discuss about the step-by-step tutorial to root Samsung Galaxy A03.
Moreover, make sure you have the latest Samsung Android driver package installed. Samsung maintains many region-specific and carrier-specific update channels. As a result, you have to determine the exact consumer software customization code, AKA the CSC value of your device, before downloading the Odin firmware. Keep in mind changing the CSC of an existing device or cross-flashing a different firmware is possible, but explaining such modifications is out of the scope of this tutorial. Once the phone boots to the home screen, open Settings from the app drawer or the gear icon in the Quick Settings menu. Then, scroll to the bottom of Settings, select About phone, and choose Software information. It should be the same as the Odin firmware package you downloaded earlier.
Don’t use the manual method if you want to update a security patch to the current month. There are various reasons to flash “Stock Firmware on Galaxy A12 SM-A125U1 U4“. For example, your phone will be stuck or hang on the logo. Follow the below link to install the firmware using the Odin Flash tool. Congratulations, now your Samsung Android 12 Galaxy’s Firmware has been upgraded to the new version.
The phone goes back to its original state after a firmware update or an OTA update, so it’s mandatory to disable automatic OTA updates of the phone. It’s not required anymore to pre-root your phone with Magisk to make the procedure work. But we kept the „Disable boot patching“ option on the panel, so you can still use it for pre-rooted phones. This is a closed beta update which features a new FRP Remove solution for OPPO phones with Qualcomm SoCs.
What that means is that you no longer have to use the device as the manufacturer wanted you to. There are tons of mods, frameworks, legal hacks available by which you could completely change the look and feel of your device. Among them, installing a custom ROM is the most preferred choice of tech enthusiasts.
