Success ! I rooted my B3-A30 with MagiskManager....

Hi folks!

As this is my first post here - I'm not allowed to post "outside links" - so I have to write them ugly and not clickable.... :eek:

Yesterday I successfully rooted my B3-A30 after trying several methods... This one worked for me (following this guide : forum[DOT]hovatek[DOT]com[SLASH]thread-21427.html , using fastboot method).

!!! ATTENTION !!!

FOLLOWING THIS PROCEDURE - YOUR TABLET WILL DO AN FACTORY RESET

!!!!! - A L L D A T A W I L L B E L O S T - !!!!

Short procedure:

1. Forget SP-Flashtool for this tablet. This Tool is great (i love it - thanks to the dev's) - but it never worked for some reason with my B3-A30 :(

2. Get MagiskManager APK and put it on the Tablet (use SD-Card as the Internal Storage will get resetted later) : github[DOT]com[SLASH]topjohnwu[SLASH]Magisk[SLASH]releases . (Later, you will have to run it on the Tablet)

3. Get the stock ROM (link from previous posts : www[DOT]mediafire[DOT]com[SLASH]file[SLASH]v6i6oevdct9766c[SLASH]Acer_Iconia_One_10_MT8163.zip)

4. Extract stock ROM. You only need the "boot-sign.img"

5. Put the boot-sign.img on the Tablet

6. On the Tablet : run MagiskManager - Select "Install>Install>Patch Boot Image File>..." navigate to the "boot-sign.img" - MagiskManager will automatically patch the file and store it under SDcard/Download/magisk_patched.img

7. copy the "magisk_patched.img" to your Computer and disconnect tablet from computer

8. On the Tablet : allow USB-Debugging and Bootloader-Unlocking (to use ADB and flash the boot image)

8.1. enable Developer Mode : Settings->System->About(Tablet)->Tab 5 times on "Build-Number"

8.2 enable USB-Debugging : Settings->System->Developer: Enable OEM-Unlocking and enable USB-Debugging

9. On the Computer you now need "adb" and "fastboot" (i'm a gentoo-linux-user - i don't know how to get adb for other unix'es or worse : windows... :silly: - on gentoo-linux you simple install adb and fastboot with "emerge dev-util/android-tools" )

10. open your favourite terminal

11. connect tablet to your computer

12. on the tablet you may have to allow adb-access for your computer

13. on computer-terminal type : "adb reboot bootloader" - your tablet should now reboot in "fastboot mode"

14. on computer-terminal type : "fastboot devices" - you should see one device (an id followed by the word "fastboot")

BE WARNED - THE NEXT 2 STEPS WILL ERASE YOUR USER PARTITION ON THE TABLET (FACTORY RESET)

15. on computer-terminal type : "fastboot flashing unlock" - your tablet will ask you for confirmation - you should ALLOW it by hitting the "VolumeUP" key on your tablet

16. on computer-terminal type : "fastboot flashing unlock_critical" - your tablet will ask you for confirmation - you should ALLOW by hitting the "VolumeUP" key of the tablet

17. on computer-terminal type : "fastboot flash boot <PATH TO magisk_patched.img>"

18. after flashing - wait some seconds - make some coffee or smoke a cigarette (i dont know why - but waiting was significant for me for some reason)

19. reboot tablet : on computer-terminal type : "fastboot reboot"

20. you will now have to setup your tablet again (Notice: you will need Internet connection for the next step)

21. on tablet : install MagiskManager.apk again and start it. It should now inform you, that magisk is installed.

CONGRATULATIONS! :cool:

Addendum:

For some reason i had to flash the magisk_patched.img 2 times before it worked - don't know why.... :eek:
