How to easily unlock bootloader and root Acer Iconia A1-810 tablet with Android KitKat 4.4.2

First, download and extract 'A1-810 Unlock and CWM' archive from here, here or here. This is very easy, it only takes 5 minutes, just read carefully and follow  the instructions.

Attention! Author of this guide is not responsible to any damage you got when unlocking! Only for 4.4! Warranty will void! You won't be able to flash original Acer updates!

Installing the driver
1. Find 'Drivers' folder in the extracted archive. Disable signature enforcement if you're on Windows 8 / 8.1.
2. There are two executable files:
2.1 Run install_driver.exe as Administrator if your OS is 32-bit.
2.2 Run installdrv64.exe as Administrator if your OS is 64-bit.
3. Wait 2 minutes. There's no feedback from installer.
4. Reboot PC and connect turned-off tablet to it. New drivers may be installed.
My PC has Windows 8.1 Pro x64 and everything worked just fine.
Preparing to serious work
1. Backup all your data!
2. Back-up all available data and MAC addresses
3. Charge your tablet on 100%!

Unlocking bootloader and installing CWM

1. Download an archive and unpack it in short path, for example in C:/

6. Memory type: EMMC.
7. Start Address: 0x3D80000.
8. Copy "File Size (bytes)" to Container Length field.

9. Press "Write Memory".
10. Connect your turned-off tablet to PC.
11. Progress bar will fill with red, then with dark green.
12. After this you will see a green circle.
13. Disconnect the cable. DO NOT try to turn your tablet on!
14. Go to "Download" tab.
15. Check files:
PRELOADER "/810 Unlocking and CWM/preloader_unlock.bin"
RECOVERY "/810 Unlocking and CWM/recovery.img"
If you are using Rescue folder:
PRELOADER "/810 Rescue/preloader.bin"
RECOVERY "/810 Rescue/recovery.img"

16. Press "Download" and connect the cable again.
17. Progress bar will fill with red, then with purple, then with yellow.
18. After this you will see a green circle.
19. Disconnect the cable, wait 5 seconds and try to turn it on!
19.1 If all was booted OK, try to boot in CWM.
19.2 If A1-810 is not reacting to Power button, then run Guide #3 using Rescue folder.
19.3 Stuck on Acer logo? Press Reset and retry!

Hi Dan, I followed the above and everything went smoothly and seemed to work fine. CWM recovery works great and I can now backup and restore which is awesome! I then flashed the SuperSU zip which also seemed fine.

Problem is that most of my root apps say they can't access the file system as though they can't get RW rights on the /system partition? Other root apps that don't need write on the system work perfectly, so it seems to be only half rooted but the file system is still read only & can't be set to RW? Can you help troubleshoot?

I have tried re-doing it all from scratch but still the same. Also when exiting CWM I get a question whether to restore root or not so even CWM sees a problem. Thanks heaps for your good work so far! Dennis.

Thanks a lot! Worked like charm! The only thing: The 64bit driver didn't worked on W7 x64, but the x86 worked fine on my 64bit system

...\ CWM ok, but during supersu flashing it says ERROR. :\

hola la app freedom no me funciona me sale este mensaje... "write permissions on system partition are required in order to use freedom" alguna ayuda para poder usar la app... gracias

Unknown said...

Hola.freedom will not work, just like lucky patcher and others.because we don't have system r/w permissions (apps can't modify or write to system partition) and this is because of the kernel is still unlocked (Acer still don't want to publish the source code)
