How to Flash TWRP & Root Samsung Galaxy A10 series (Unlocked Exynos Only)
Before moving to root device, must read every single instruction given below as any small mistake can lead to fail to achieve root or may brick the device.
A. Unlocking Bootloader
This is a basic step to root device. Go to settings - about phone - Software Information - tap multiple times on "Build number" - This will open developer option.
Now in settings at the end, you will have new option "Developer options" - look for OEM unlocking - Enable it.
(PS : If you don't see this option then you may need to wait up to 7 days or more to appear or may be on some operator you will get it never. Without this option you can not root your device, sorry!).
How to get OEM Unlock option back?
Once you have enable OEM unlock option, switch off your device and reboot to download mode.
To put device in download mode - Press Volume Up & then Press Volume Down (Keep holding both) and connect device to PC with USB cable
When device start to download mode, long press volume up to unlock the bootloader. This will wipe your data and automatically reboot
Now let finish setup and again enable developer options (as said above), and confirm that the OEM unlocking option exists and grayed out!
If it is not then you can not root device!
Once you see this option and greyed out, you are ready to flash custom binary and root your device.2. setup the phone by skipping the wizard.
B. Disabling Android Verified Boot
1. Reboot to DOWNLOAD mode.
2. Download Odin 3.14.4 or newer and make sure Samsung USB drivers are installed.
3. Open Odin and put the
vbmeta_disabled.tar into USERDATA slot and click "Start"
4. Your device will reboot but it will not boot into system as vbmeta signature has changed.
5. Your device will reboot into RECOVERY mode automatically and prompt "You have to reset your device to factory settings". Use "Volume Up" or "Volume Down" button to move and "Power" button to select. Confirm and reset the device to factory settings.
6. This is the last time the data on the device has to be cleared. Afterwards, if you don't re-lock bootloader or re-enable the Android Verified Boot, you will not lose your data. Be aware, a stock firmware package contains a Android Verified Boot Metadata Image (vbmeta.img) with verifications enabled. You will need to flash the vbmeta_disable image (put into USERDATA slot) along with the stock firmware (use BL, AP, CP, CSC slots) to make sure AVB is not re-enabled and the data is preserved.
C. Flashing TWRP/Magisk
1. Reboot your device to DOWNLOAD mode.
2. Download TWRP for your device from
here.
3. Put the recovery TAR flashable into AP slot, Click start.
4. Immediately use Volume Up + Power to reboot into recovery mode.
5. Download multidisabler-samsung-*.zip from
here and copy to Ext Storage (Because once you flash TWRP, Int storage will not be readable)
6. Install multidisabler-samsung-*.zip
7. Reboot to recovery and select WIPE - Format Data
8. Install Magisk via recovery.
9. Enjoy!
Done! Now you have TWRP with Rooted device.
PS : Once you Install patched TWRP and flash multidisabler*.zip, your OEM unlock option will set to Off and can not be turned ON because of hacked OEM function. This is made intentionally to prevent official binary error.
Important :
Due to the fact that some devices no longer uses ramdisk in boot images, Magisk has no choice but to be installed in the recovery partition. For these devices, you will have to boot to recovery every time if you want Magisk. Since both Magisk and recovery lives in the same partition, what you actually end up getting when you choose to boot to recovery will be determined by how long you press volume up.
- (Powering up normally) → (System with NO Magisk)
- (OEM Recovery Key Combo) → (Splash screen) → (Release all buttons) → (System with Magisk)
- (OEM Recovery Key Combo) → (Splash screen) → (Keep pressing volume up) → (Actual recovery)
