[Samsung Galaxy A10 Guides, News, & Discussion] mikeyb123:
Hi All this is just a quick tutorial to help you all root your devices, on later firmwares

This 100% works ive done it over and over without any problems. I am currently on october patch latest firmware for my A105FN. As you may know Samsung have now added extra security meaning even if you have already unlocked your bootloader after you patch the firmware with magisk, flash patched firmware and reboot you will be greeted with that dreadfull message, Only official binaries allowed and your device will be locked and wont boot untill you reflash stock firmware again. The below will help get you out of the prenormal kg state, and save's you a 7 days waiting period as we dont have any TWRP available for our device at this time. Also note due to the extra security magisk cant be flashed with the whole firmware no more, as each time you flash the firmware your back at square 1.

Note: You will need 7-zip - google is your freind

1. Download odin: https://odindownloader.com/download/odin3-v3-13-3.

2. download the latest stock firmware for your device via SamMobile

3. Download latest Magisk Manager - https://www.google.co.uk/amp/s/xdaforums.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445/amp/

4. Flash latest firmware via odin and let device boot up and finish setting up.

5. Grab Your Firmware AP_A105FXXXX.tar.md5 remove the md5 so its a tar file makes it easier to work with. Copy it to your device storage.

6. Install latest magisk manager, and open check advanced settings to make sure recovery is checked, select install image / patch image and select the AP file you put on your device, magisk will patch and save as magisk_patched on your internal storage. Copy this back to your pc and extract it.

7. Download this https://xdaforums.com/attachment.php?attachmentid=4818715&d=1568308074 thanks to [MENTION=5513307]droidzer1[/MENTION] and extract the vbmeta.img.

8. Make a new folder on you pc it's temporary so you know where your files are. From the Ap magisk_patch.tar you extracted, copy the boot.img, recovery.img, and the downloaded vbmeta.img from step 7. And place them in the new folder you created, using your mouse select all 3 and right click select 7-zip add to archive, select tar format and name it magisk.tar.

9. Now we have all the files ready back to your device, if your bootloader is already unlocked skip this step and move to the next. For those that havent unlocked there bootloader 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, if the OEM switch is not there proceed to step 10. If it is and you enabled it it might ask you to factory reset if not it will be this way to complete the unlock bootloader.......

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.

10. Remove any account you have on your device go to settings, look for time and date automatic time zones, turn it off and set date back 8 days from now (example 30th today change date to 22nd) restart device. Now go straight back into automatic time zones settings and turn it back on. Again reboot device, when device reboots turn it off. You can now enter download mode and it should say checking instead of prenormal that means you good to go. Those of you that had no OEM switch in developer mode please now check.... if it's there enable it and go back to step 10 unlocking bootloader then proceed to step 11.

11. Open odin and select in the ap tab the magisk.tar you created earlier. Plug in your usb whilst holding vol-up and vol-down together to boot into download, press vol-up to proceed. Press start on odin and soon as it finishes and device reboots and you see the bootloader message hold power and vol-up until into stock recovery, select wipe factory reset then select reboot device, this the same as soon as you see bootloader unlocked message hold power and the vol-up together this time count to 7.... and release. Phone wont boot it will go blackscreen and reboot, dont worry this is normal, again do the exact same at bootloader unlocked msg screen hold power and vol-up count to 7... release, now phone will boot and you can set it up.

Note: you will need to reinstall magisk manager and on 1st open it will ask do to additional setup, let it do its thing, then device will reboot,

Remeber every time your device reboots you will have to do the power and vol-up to boot system with root.
