Stragulus here who wrote the instructions above:

* 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.

I have dd .img's of all my partitions from before the screen was broken. IT should have all the files i need to do everything described above. Welcome to Androidtablets.net !

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?
Tried it, still didn't work, I don't get it, I'm on hwver 184.108.40.206, I'm using the right file...I don't know what that word is coming up on the 'status'...I'll try to download the ius file again and keep trying.

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
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 (220.127.116.11.2.0_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
-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
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 Disgo 6000 updated to DG2.20 (Android 2.2 "Froyo") so Disco owners can quickly find your information.

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 disgo Tablet 6000 - Hardware version & Settings.apk.
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. Odd Wifi problem...
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.
