I have tried everything I could after using the Lickonn recovery image, and I still cannot get into Recovery Mode. Quickboot just cycles through as well, without going into it.

If I hold the hardware keys down, I get 2 or 3 quick vibrations, and an icon ( I think it's a speaker phone or message one) flashing on the top of the unit, but nothing on the screen. I have searched the threads, and found nothing I can use to assist.

Can someone help?

search first, go to adb with your phone normally on:

adb reboot recovery

but try flash recovery again
to enter fastboot:

adb reboot bootloader

The first command causes the unit to display "Acer" then the green androids. Then it shuts down, and does this again. Ending in the home screen.

The second one enters fastboot. I am trying to flash Lick's custom ROM. I have root access.

Ok, flashed and verified. I don't have the recovery image on the Liquid, it's on my PC.

Still nothing. It repeats the steps I outlined above.

Aren't rookies fun? :)

the image stays on your computer

you need fastboot for your Operating system to write the recovery.img

place the recovery.img on the folder of Paul's superboot that you use to root the device
enter that folder and with your phone normally ON type

adb-windows.exe reboot bootloader

it will reboot fastboot , then type:

fastboot-windows.exe -i 0x0502 flash recovery recovery.img
fastboot-windows.exe -i 0x0502 reboot

it will reboot normally, to enter recovery:

adb-windows.exe reboot recovery

it will reboot in recovery mode

Followed step by step. Exactly as you've written it.

The unit repeats the same thing. Acer, then Android. Black. Acer, then Android...then home screen.

I'm stumped. Completely.

Same problem here.

Tried the exact steps to Re-flash recovery and enter recovery mode. No luck.
Also tried to Flash using Acer Download Tool - Just gives me "Not in OS mode error"...

Piter1225, Could you please let us know how to boot into recovery using QuickBoot?

Thanks very much you were very helpful.


I just did not know this is an Application you download from AndroidMarket. I assumed it should be part of SDK as adb.

Well that did not work either. Boot Acer > Android then reboots again Acer > Android > Home Screen.

then you might not even have a recovery flashed.
Can you get into bootloader mode? if you can try and reflash the recovery

If you rooted your Liquid with the anternate "root" V1.1, it could happen like that. Since that's exactly what I go through.

I fixed it by update to 2.005 ROM, then update again the second time, but have task manager kill acer downloader as soon as fastboot screen comes up. Then I rooted the phone with the normal "root" v1.4 and loaded the lickonn recovery image. And it worked perfectly from there.

Hi Goa200,

1. Yes I can get into bootloader.
2. I have tried to re-flash recovery several times. The bootloader returns this.

D:\android\tools>fastboot -i 0x0502 flash recovery recovery.img
< waiting for device >
sending 'recovery' (4876 KB)... OKAY
writing 'recovery'... OKAY

on the handset it even says Verified... OKAY

I suppose that means that recovery is flashed? I have tried Lickonn recovery. Maybe I should try something else?

How do I update to 2.005 ROM ? I cannot get to recovery mode and the Acer Download Tool gives me "The phone is not in OS mode error". ?
BTW - i have rooted it using SuperBoot from Paul http://android.modac...ing-the-liquid/


Thanks for help.

boot your phone normally, when it is in the launcher the Acer Download tool you recognize the phone and allow you to download the ROM onto the phone.

I turn off the phone, connect USB, Start Acer Download tool, Start Up the phone, click on Start in the Download Tool. And it loads into home screen. The Downloader jsut gives me this error:

[Lock] Security... has exception : System.InvaliOperationException: The port is closed at System.IO/Ports/Write


Still trying to figure it out.

Same issue with Umka.

If I cannot get into the Recovery mode, how can I use Nandroid to backup my original data inside phone before upgrading firmware?

My firmware is Acer_Liquid_1.001.04_AAP_FET.

Thanks.

I would even upgrade without doing backup and reinstall/resetup everything from scratch. just cannot upgrade without getting into recovery mode. :) B)
