I flashed Lightspeed_4_beta3 after that came out and I finally made the time to try and update to the newest version 4.3 today, but I can't get into recovery, I have Acer Recovery app and I re-installed CWM but it still wont load recovery... any ideas why? and how to fix it?

Go to market and get the app called "Rebooter". It gives the option to boot into recovery, dowload, reboot or power down. This needs root to work though...

I know how to boot into recovery, that's not the problem, the problem is it wont load CWM recovery at all, it says loading recovery and it should only take a few seconds but I left it for 5 minutes and still said the same thing.

Welcome to corrupted data. You know how to use ADB? You might be able to push a recovery image, but you'll need to format the devblk first I suspect.

Hope you have a backup copy of your UID number. I think you will probably need it.

I;ll say, go back to stock. Run Timmy Deans tools. It'l put a rooted stock 3.2, then install acer recovery with thor.

In the future, I would install RA Recovery. You can flash it from CWM.

I have used ADB for my phone before, I'll look and see if I can push RA Recovery on without going back to stock, because I don't think I have my UID number anymore. Thanks for the idea, I guess I can try that see if I can get it working that way.

I believe Thor has instructions for pushing the CWM image on his site at tegraowners. As now you cannot flash an install.

I also suppose, you might try AcerREcovery from the market, and see if it would flash CWM again. Might be a little easier.

Unless I have misinterpreted something, this should not be that much of a problem. Maybe a bit inconvenient if you don't know USB programming though.

If you can get the device into APX mode it will answer the first read request with the UID.
So if you open the device (955:7820) and initiate a bulk transfer on endpoint 0x81 and you should get 8 bytes that is the UID.

Something like:
Code:
#include <libusb-1.0/libusb.h>
#include <stdio.h>
#include <stdint.h>

int main(void)
{
    unsigned char data[64];
    int received_length;
    int r = 1;
    libusb_context* ctx = NULL;
    libusb_device_handle* dev_handle = NULL;

    libusb_init(&ctx);
    dev_handle = libusb_open_device_with_vid_pid(ctx, 0x0955, 0x7820);
    if(dev_handle)
    {
        r = libusb_bulk_transfer(dev_handle, 0x81, data, sizeof(data), &received_length, 10000);
        if (r == 0)
        {
            if(received_length == 8)
            {
                printf("uid: %#016lx\n", *(uint64_t*)data);
            }
            else
            {
                r = 1;
                printf("Error: We got %d bytes of data insetad of the 8 bytes we expected...\n", received_length);
            }
        }
        else
        {
            printf("Error: USB read failed!\n");
        }
        libusb_release_interface(dev_handle, 0);
    }
    else
    {
        printf("Error: Failed to open device!\n");
    }
    libusb_exit(ctx);
    return r;
}

I have been sooo fustrated trying to get my iconia rollback from the ics leak.

I tried SEVERAL methods including this one http://forum.xda-developers.com/show...2#post23850482 in a thread i just posted.

But still no luck =( Every time i try to boot into recovery mode i get "Recovery verified failed" in read text and it just sits there and wont boot into recovery.

Can someone PLEASE tell me how to fix this or a way to get rid of this error. I dont care if i have to go back to stock i will.

Thanks guys
