I am a newbie in this forum and would need some help to unbrick my tablet.

I have been using leaked ICS in the past 2 weeks or so. This morning when I started using the tablet, it was running VERY slowly. I rebooted it but it was stuck at Android screen for more than 30 mins. Running out of patient, I restarted it 1 more time and it can now only get to the Acer screen no matter how long i waited.

Tried a few things already with no success:
1. Hard reset using the pin hole bottom left - nothing changes
2. Go to recovery mode trying to use the HC rom (rename to update.zip) using volume up button. Once the green droid shows up for a few seconds, it turns into a droid lying down with a red exclamation mark. It will then restart itself after 30 seconds or so.

What's going on with my tablet? Any help would be appreciated.

Cant use HC ROM...
As long as you are not BOOTLOADER UNLOCKED you can use a regular UPDATE.ZIP for your device... You cannot "DOWNGRADE" that is, you cannot go from ICS to HC again without some form of "hack" or "workaround"

See if your tablet allows you to re-flash the ICS build you were able to update to and post back... It may just be it corrupted some files...

Let us know... jejeje


UPDATE 1: And... Dont use VOL+, its supposed to be VOL-.

I tried the vol - button (the one farther away from the orientation lock button), it seems like the tablet was not doing anything different at all. It will eventually get stuck at the Acer screen.

If i use the vol + button (the one closer to orientation lock button), it shows the text "Booting recovery kernel menu" in Acer splash screen. It will then go to green Droid screen with a spinning sphere. In less than 5 seconds, it seems to fail to boot into recovery menu with a 'dead' droid with a big red exclamation mark.

These are the update.zip file I found in the forum. They all gave me the same error:

Acer_AV041_A100_1.012.00_WW_GEN1.zip
Acer_AV041_A100_1.014.00_WW_GEN1.zip
Acer_A100_1.014.08_COM_GEN1.zip

Any more help? I can get upload a video to Youtube if it helps.

HOME Button?? Maybe??
When you get to the GREEN ANDROID... click on your HOME button and see if you get a bootloader/recovery type menu at the top left... If you dont get it from the GREEN ANDROID, try thesame (HOME button) while the RED DEAD ANDROID is showing...

When mine did that for a bit, I found there was a "hidden" recovery built in... Again, try to go to recovery and press the HOME button... You may have to press it for a few seconds...

Thanks for the pointer! It now shows a lot more information (while the sad Android with red exclamation mark is in the background)

I can scroll down/up using volume button for these options:
  1. reboot system now
  2. apply update from external storage
  3. wipe data/factory reset
  4. wipe cache partition
  5. apply update from cache

At the bottom of the screen, it is showing a whole bunch of yellow text:

E:Can't open /dev/block/mmcblk0p5
(No such file or directory)
E:failed to mount /cache (No such file or directory)
E:Can't mount /cache/recovery/command
(repeat the above message for /cache/recovery/log, /cache/recovery/last_log, /cache/recovery/last_install

How can i select an option from this menu, btw?

I also tried to use the vol - button. I found that if i keep flipping orientation lock back and forth, it will show 2 messages at the top left corner showing "Erasing Userdata...Erasing cache..." in the Acer splash screen. Then it will freeze again....

PWR button to select
Make selection with Vol+/- and press PWR button to select... See if you can do a factory reset...
"
Or put the UPDATE.ZIP into your microSD and see if it lets you select the "Update from ZIP" message

Pressing the power button doesn't do anything. If i press it long enough, it just shuts down the tablet.
