    I suggest you take that your problem over to XDA Developers where most of the hard-core hackers hang out.

    You can get a tee-shirt to help you remember your predicament.

    Yeah, they must try Icebike. And when it goes wrong or something doesn't work then they cry!

    Sorry to be abrupt but if you follow Icebike's suggestion then you would get the help you need. I personally would not do to my A500 what you've done to yours. But you are not the first! Unbricking a tablet may or may not work. What most people don't realise is that they could lose their warranty - if you find you need tonsend your tablrt in for repairs. And this, and my posting before, is not spam!

    Icebike has given you sound advice. and FYI I do not approve of rooting an ACER into thinking it is an ASUS, or vice versa. Especially if one is not familiar with ANDROID OS.

    For me the ACER does all it needs and I don't need to root my tablet to access its system.

    Darvish, I just had a look at xda_developers just to find out your issue. If you don't follow their instructions how do you expect your tablet to work! If you've overwritten the recovery system then I'm sorry you may have send your tablet in to ACER. That is why you have only one selection. And you may lose your warranty - you're at the mercy of ACER.

    you are wright sir i think my tablet is damaged by myself and warranty doesn't have meaning in my country and i have no one in other countries with responsible acer supporting centers
    but i think a good tablet is a tablet with flexible os and you must be able to test many roms with different abilities for best performance and i think acer dont want this ideas
    why them didn't publish a method to root 3.2 stuck roms?
    is android os a closed source os like win or mac?
    however i am so glad for your attention to my problem and your advises

    You are right in one thing - ACER has locked down their OS on the tablet. Their reasoning is that the OS remains stable - 9 or 10 months of stability has proven that and I haven't had any problems.
    Also, once you root your tablet it will not receive OTA updates - you will not get ICS when it is released for the ACER. ANDROID is owned by GOOGLE and it is open scource but manufacturers of tablets will option their units as they see fit and what they consider best for their product. It is like a car where the transmission (gearbox) is (I would equate Android with the gearbox) is standard as per manufacturer specs. You can change the gearbox and you will get many different results - good and bad depending on your perspective and what you want to achieve.
    I'm sorry you have the problem.

    Did you successfully update CWM to the latest version 1.7?
    What custom rom were you trying to install?
    Did you wipe out the data and clean it before install this custom rom?
