How To: Root the Acer Liquid

THIS PROCEDURE IS NOW OBSOLETE, PLEASE HEAD TO OUR HOW TO ROOT USING SUPERONECLICK PROCEDURE INSTEAD.

I. Before You Begin

1. This will give you root access and upgrade you to Android 2.1

II. Download and install the Liquid Drivers

1. Download the drivers

Acer Liquid Drivers (x86 for 32bit Windows, x64 for 64bit Windows)

2. Click Acer Liquid Tool Setup and follow the steps to install the drivers.

III. Flash the Firmware with the Acer Flashing Tool

1. Download the Acer Liquid 2.1 Firmware

Acer Liquid Rooted Firmware

2. Save the .bin file somewhere on your computer that you can find it easily later.

3. Download the Acer Flashing Tool

Acer Flashing Tool

4. Run the Acer Download Tool and click Browse. Then look for the .bin file we downloaded earlier and click that.

5. Connect your phone to the computer via usb and then click Start in the Download Tool.

*I ran into an issue where it said Not Connected while Starting AMSS. Wait a good 5 minutes and if it is still stuck, remove the usb cable and put it back in, this fixed it for me.

6. Once it reboots, goto Menu > Settings > Applications > Development > Check ON USB Debugging.

IV. Install Superboot and Custom Recovery Image

1. Download Superboot2.zip

Superboot.zip (updated 6/23/10)

2. Unzip the superboot.zip file.

3. Double click on the reboot-bootloader-windows.bat file and wait for the phone to boot into bootloader mode.

4. Then double click the install-superboot-windows.bat file and wait for it to finish. The phone will reboot.

5. Double click on the reboot-bootloader-windows.bat file and wait for the phone to boot into bootloader mode.

6. Then double click the install-recovery-windows.bat file and wait for it to finish.

7. Once it reboots, you are all set! You have root access, Android 2.1, and a custom recovery image to flash ROMs with!

NOW, you can load custom ROMs! Head over to our How To Load a Custom ROM on the Acer Liquid procedure for how to get started.

    thank you, this guide helps me a lot. i have black death screen when i download official acer android 2.1 to 2.2. and i was soo confuse. i follow your guide, with little modification, and now i can get official 2.2 froyo on my phone.
    here step i did:
    1. download and install acer liquid drivers
    2. download acer flash tool
    3. download acer liquid e roms.
    tips: if you don’t wanna root, you can pick non rooted roms. i get mine 4.005.05.AAP.GEN2_A22F (For Liquid E 512MB) from here http://android.modaco.com/content/acer-liquid-liquid-modaco-com/317068/acer-liquid-liquid-e-all-roms-bin-extract-collection/
    watch carefully on your device type and how much memory it has.
    5. unzip acer flash tool and your rom
    note: i don’t want my phone rooted, so i skip install superboot. (but maybe gonna try later :P)
    4. run acer flash tool file “ACER Download Tool [Single]” by clicking right mouse and pick run as administator.
    5. browse file to your selected roms.
    note: it may gonna prompt “incorrect roms size” or something and MD5 fail, you can ignore that.
    6. connect your phone through USB cable. acer flash tool may recognize it through COM10, if not, do this: unplug your phone usb, take the battery off, wait around 5 sec, put it on again, connect again your phone usb, then do fastboot on phone by clicking volume up + camera button + power, your phone will vibrate twice as sign it do fastboot. then acer flash tool should recognize it.
    7. start acer flash tool, wait till finish.
    note: i encounter problem that it stop for a while and said “not connected”, i’ve tried to unplug and plug again usb but it didn’t works. so here what i do, unplug usb cable, close acer flash tool (by windows task manager (ctrl-alt-del, pick task manager, close acer flash tool on application tab) to close it), and start again acer flash tool, take off and on again your phone battery, plug the usb, and do fastrboot (vol up + camera + power). and start again acer flash tool, this second attempt should go smoothly.

    wait till finish, done. close acer flash tool. take off and on again phone battery, and do usual boot (pressing power button). your new rom applied XD.

    does this also work on acer liquid E?

  • Rob Lund

    I have an unusual problem. When I press the three-key combination (camera, vol, power) nothing happens.

    I suspect that the part of the Flash that recognizes this is corrupt. I tried to upgrade my Acer Liquid E to Froyo . Unfortunately, in my hurry, I installed the FIDO upgrade instead of the Rogers upgrade. This killed my phone. I then used the Acer Tool to download the boot bin file to the phone, and I got my phone back. Now I want to do the Froyo upgrade properly, but it doesn’t do anything when pressing the three buttons.

    Anyone got any ideas? Perhaps I need to download other bin files to the phone?
