    I've done all the steps of for the USB Mode method, the driver loads, the "Dv." turns green, but when I click burn...A word (something japanese or chinese) comes up under the "status" column and it stays at "0%"...then the tablet starts up. I've uninstalled the driver, rebooted, and tried again, and again, nothing...any thoughts

    I would say when all else fails... try it after a clean wipe...

    It doesn't mention starting from either a clean wipe or a ugly hacked device in the instructions...has anyone successfully done this while having Android Market on their tablet? I understand that I would LOSE it on Froyo 2.2 and I'm willing to take the risk, but I need to make sure that the process would work if I do a Clean Wipe, I would hate to do the Ugly Hack all over again. and BTW, Kudos for doing all this, you guys ROCK!!!!

    okay pieces of info on extracting uboot, kernel, etc from an ius.

    1st you have to use a hex editor to search for gzip headers

    Source
    source

    This is important to me because if i can learn how to get the system out i may be able to manually insert a touchscreen calibration file and be able to use my tablet for dev work without a working touch screen. It's important for everyone else because if we know how to extract it we can actually start building custom roms etc.

    And I think, from what I have seen and read, that it might not be necessary to build a rom from the ground up.
    If we can extract the IMG files.. and replace them... couldn't we say Pull the old "Mt device" explorer with the FTP connection from the DG2.02 and then inject it into the new Froyo 2.2 to replace the "My Pad" explorer? Or for any other apk that the system uses as default?

    Just a thought.

    Stragulus here who wrote the instructions above:

    For just the pointer calibration, you only need to modify the ramdisk (ramdisk.img). What you basically need to do:

    * Locate & extract ramdisk.img in the .ius image
    * Add a pointer calibration file to the image (you will need to get one from someone who has already calibrated their tablet!)
    * Add instructions in init.rc in the ramdisk image that will copy this pointer calibration file to the path where the tablet expects it
    * Recreate ramdisk.img
    * Flash it to the tablet (I didn't read through this thread but I think you can do this using an sd-card method as well? If so, dump it on the sd-card as android/ramdisk.img, remove all the other files in that dir, and boot the tablet off of it)

    So first thing you need is the pointer calibration file. Someone here who has rooted their tablet should look it up, on all other infotmic tablets the file is /data/misc/tscal/pointercal

    Once that is available, I can help with the other steps.

    If the files is stored in /data could i just use the burn tool to burn my entire backed up data folder in theory adding the calibration file to where it needs to be?

    well, that was pretty painless!
    since i have win7 used the OTG method, worked great!
    the communicating with pc never showed until after i started the burn.
    and the first boot is night and day, i had mine rooted before with the ugly market hack, and the speed difference is HUGE! so much faster now.
    Thanks to all that made this happen, and wrote up the instructions, you guys rock!

    Also, if you have terminal emulator installed, instead of using adb, just run the command
    cat /proc/cmdline

    to get your hwver.

    Hi and thanks a lot for the information , links and tools :) - they saved my life

    I bricked my Disgo 6000 with android 2.1 by rooting it and removing some file (apparently this should speed it up according to another thread I found).
    Unfortunately I ended with a tabled that boots only up to disgo logo and stays there forever.
    On the Internet there isn't much info about this device, but I found out that it similar to Sylvania
    Ubuntu wasn't recognizing the dead tabled at all -> I switch to Win XP and while booting the tabled (black screen) it asked me for a driver .
    Did a bit of research and found this forum
    Downloaded the iuw1.1-english file and found a OTG driver in the archive.
    Installed the driver , device was recognized - waited 2 minutes and it showed "communicating with PC"
    Quite a good sign as 20 minutes ago I though this device is lost forever
    I could not find out the HW revision , but I download the first file (11.2.0.6.2.0_beta3.ius) to give it a shot as the tutorial said (Only the corresponding file to "hwver" will burn the new update.)
    Burned it , restarted - Taaaadaaa - It was alive again
    Booting up with the Sylvania logo ,but the tablet is much much faster and more responsive with android 2.2

    Other thoughts:
    -OTG doesn't work as the author said (no biggie for me)
    -Wifi seems to be disconnecting every now and then , but could be only my ...
    -Auto orientation works - yeah :)

    Hope this information is useful to other disgo 6000 users,that like to switch to 2.2 Froyo or have bricked the tablet somehow :D

    Thanks again and keep up the good work

    Okay, I've made a couple of more attempts, I don't know if it's my PC, my USB ports or something, but I took a screen capture of the program when I try to burn...if anyone knows what that word under status means..."failed" or "incomplete" or anything feel free to respond. In the meantime, I'll either look for another PC to try this on, or jus do the Market Hack again and wait...I appreciate any input here.

    Congratulations "nofxsk8"! I started a new Thread http://www.androidtablets.net/forum...go-6000-updated-dg2-20-android-2-2-froyo.html so Disco owners can quickly find your information.

    As suspected the Disgo 6000 and Sylvania tablets are very similar devices that can share firmware.

    A few questions/comments/requests -

    Can you confirm that on your "bricked my Disgo 6000 with android 2.1" when attempting "Apply a factory reset - (three finger method)" it Failed and that with the 2.2 update a "factory reset" can be applied?

    Since the Disgo 6000 and Sylvania tablets can share firmware it would be informational to know where the Disgo 6000 gets it updates. From now on, a tablet updated with the Sylvania update will query the infoTM site for the Digital Gadgets version updates.

    If a Disgo 6000 user running 2.1 could pull the "Settings.apk" and post it for inspection, the Disgo 6000 update location could be identified. A method for pulling this important file is detailed in http://www.androidtablets.net/forum...ablet-6000-hardware-version-settings-apk.html.

    Once identified any updates could be reviewed so that we could possibly utilize the best of both the Disgo 6000 and Sylvania firmwares to create a hybrid ROM.

    The Sylvania boot animation could also be replaced on an updated Disgo 6000 if a current 2.1 Disgo 6000 user would post the boot animation files. They could then be pushed to the tablet to give the original appearance.

    Finally, the 2.2 update includes a feature to allow the WiFi to "Turn Off" when the screen sleeps thus increasing the battery life. This seems to have issues that WiFi doesn't seem to turn back on sometimes. There is an updated driver for the WiFi but it wasn't included in the 2.2 update. Here is the manual process to update but unsure if it will improve this issue. http://www.androidtablets.net/forum/sylvania-tablets/9883-odd-wifi-problem.html#post57846

    Assistance by Disgo 6000 owners would greatly benefit the development of a customized update using the best of both devices features.

    Can you confirm the "hwver" of the device? An attempt to burn the incorrect *ius is suspected to Fail.

    Here are the potential Status messages -
    Code:
    iuw: Failed to get image description magic.
    iuw: Unknown type of image.
    iuw: Not a valid infoTM wrap! Magic do not match.

    iuw: Hcrc passed!!

    iuw: Dcrc passed.
    iuw: Not a valid infoTM wrap! Image count out of baundry.
    iuw: Get image %d faild, maybe the update wrap is demaged.
