I got the device which is really nice, I rooted the first night, I then updated to version 1.1, lost root as usual but luckily my copy of CWM works fine for both versions 1.0 and 1.1.
If you are familiar doing this with android phones, just follow the same steps.
Use at own Risk
Download both files. Make sure they are complete and the file sizes match.
Save recovery.img to computer, and su.zip to VSD220,
Gain access to adb for your device,
go to terminal or command prompt and type "adb reboot bootloader",
and then enter.
The screen will turn solid black,
in the same terminal type "Fastboot flash recovery recovery.img",
and enter, make sure you are in the same directory as your recovery.img.
The recovery will flash quickly, when complete type "fastboot reboot", enter.
Your device will boot up,
make sure you have Su.zip saved on the VSD220 in the directory /mnt/external_sd/su.zip,
you must have an external sd card inserted,
you can confirm this with root explorer even without root.
In terminal type adb reboot recovery,
you should have a working CWM that will allow you to flash su.zip, and perform a nandroid backup, etc.
If CWM offers to block the stock recovery, accept it.
Otherwise you will need to delete or rename /install-recovery.sh and/or /system/recovery-from-boot.p.
Enjoy Root.
This works for both version 1.0 and 1.1.
Cool, thanks!
Can't seem to get "adb devices" to come up with anything. Using Android Composite ADB Interface for driver, no luck at all.
Any help on which ADB driver to use and where to download appreciated.

Sorry, was using outdated adb.
So got adb, flashed recovery.img, recovery flashed ok, rebooted...but now when I adb reboot recovery, it reboots and then stuck on green android with red triangle.
Any advice?

Ok, I worked it out now. But for others, the problem was that recovery image was being replaced with the original on the command "fasboot reboot".
So instead, immediately after typing "Fastboot flash recovery recovery.img" I typed the following command "fastboot boot recovery.img".....AND only then did I get CWM which allowed me to flash su.zip from SD card.
Thanks for all help. Now that I have root, what changes/tweaks did you make using root?
Is there an optimum dpi to apply and are you overclocking?
Thanks.
Here is a script to reboot recovery mode; from your Android VSD220.

has anyone gotten this to work lately? The device I'm playing with has 1.3 firmware on it. For some reason, I haven't gotten adb to work on this device in windows, and in ubuntu, I can adb reboot bootloader, and it goes to the black screen, but any fastboot commands, just sits there waiting for device. Any suggestions would be appreciated.

I didn't know 1.3 was available. Is this a recent firmware? I checked a couple weeks ago.
Not sure, it's not my monitor, just looking at it for a friend. when I go to about, system update I see vsd220 system update 1.3 device system version : IMM76D.UI23ED02_VSC and same info under server version
Got it sorted out after hunting on google. it does work
problem with adb
Ok so i got the device being recognized on my XP machine. Really did not have to do much. Just pluged it in and everything worked.
On my Windows 7 machine when i plug in the device i only see the MTP installed and then see VSD220 in MY COMPUTER and can browse the files. I do not see it when i "adb devices".
1) USB debugging is on/enabled
2) Both laptops have Eclipse with latest ADB and ADT tools installed
Any suggestions as to what i can do? Anyone can copy over drivers that are working with your win7 machine?
Confirmed Working for Acer DA220HQL (atleast for me)
Thanks to sk8tingusmc for posting the instructions. I followed them as well as the comments below and rewrote the instructions to reflect what worked for me on my Acer DA220HQL Smart Display. Which seems to be about the same device as the Viewsonic VSD220
Use at your own Risk - Acer DA220HQL
1. Download both files from the first Post (Thanks to sk8tingusmc).
Make sure they are complete and the file sizes match.2. Save "recovery.img" to your computer, and copy su.zip to the Acer DA220HQL to "/mnt/external_sd/su.zip"
3. Press Windows Key + R to open the Command Prompt or Start > Run > cmd > Enter
4. At the Command Prompt change to the Directory with adb.exe in my case "C:\Temp\sdk\platform-tools"
Download SDK from here: http://developer.android.com/sdk/index.html#download and extract in my case to C:\Temp (C:\Temp\sdk, C:\Temp\eclipse, and C:\Temp\SDK Manager.exe)5. At the Command Prompt type "adb reboot bootloader" and hit enter.
The screen will turn solid black6. At the Command Prompt Type "Fastboot flash recovery recovery.img" and hit enter.
Make sure you are in the same directory as your recovery.img.
The recovery will flash quickly
C:\Temp\sdk\platform-tools>Fastboot flash recovery recovery.img
sending 'recovery' (5688 KB)...
OKAY [ 0.176s]
writing 'recovery'...
OKAY [ 0.983s]
finished. total time: 1.163s

I was wondering what ROM Version is your DA220HQL on (ES I think?) and will the instructions work in Linux or other *nix like systems?
The main problem I have is that I do not have any drivers so adb in Windows XP will recognize it. It is recognized under Ubuntu 12.04 for me.
Thanks for the info! I am very excited to get this working better than out of the box!

There are a universal ADB Drivers for Windows.
Universal Naked Driver for example.

Or the following link which I have no clue about who maintains this site and how secure it is running that Exe. So please check first for yourself before yelling at me. http://adbdriver.com/
Regarding the ROM Version I was on, check the other Thread where I listed them all.

Well I got the ADB driver installed and I can use it! However I tried the root procedure and it failed to root.
When I was in the CW, the one thing it kept giving an error such as cannot mount sdcard. I checked the sdcard and su.zip IS on it, but the recovery could not locate it. I did try using the sideload method and it seemed to work, but when I rebooted and checked for root, it was not successful.
I tried this in both Ubuntu and Windows with the same result. I even performed a factory reset and tried again. And the same thing: no root.
Is there a timing issue with when to enter the commands?
The info on my DA220HQL from about is as follows:

So you were able to load CW but when you select "Choose from SDCard" it could not find su.zip? Or did you try to Mount your SDCard? Regarding the ADB Commands you can take as much time as you want. Have you used CW before?

I did try to mount the sdcard, but I got an error that said it could not mount the sdcard. That is when I tried the sideload method. When I boot up normally, the sdcard is there along with su.zip. I posted the info on my DA220HQL noting the kernel version. I went back to the post where you stated your kernel version. They are different. Mine is later than yours.
After going through everything several times, I though maybe I was doing something wrong. We went out of town so this is the first time I could sit down and check out the posts.
Thanks for your help in advance.
Thanks for all the help. I could not get this to root so we are sending it back to HSN. As a last ditch effort, I did a factory reset and tried again. And I got the same result. I do not think that the recovery while booted was able to "see" the device's partition at all, which is why I got the mount errors. In any case, I also have found that we can find it online for much less than what HSN charged us for it. I am still curious if anyone else was able to root this little gem.
Keep posting updates!
im getting the same issue
cwm is not mounting my sdcard
android is recognizing it, but not in recovery
I'm thinking I shouldn't have installed that update
there are a bunch of errors in recovery when starting
E:Can't open /dev/block/platform/omap/omap_hsmmc.1/by-name/misc (No such file or directory)
E:Can't mount /cache/recovery/command

E:Can't open /dev/block/platform/omap/omap_hsmmc.1/by-name/misc (No such file or directory)
my best guess is we need a different recovery img, even though acer is the same as viewsonic
also there is no prompt to disable stock recovery being reinstalled
recovery touch is also kind of wack, have to tap below whatever I want to pick (which is also not consistent horizontally)
edit: going back to recovery, under mounts and storage, it doesn't appear to have permission to mount anything
looks like viewsonic released a rooted ROM on their support site
http://www.viewsoniceurope.com/uk/support/downloads/drivers/?prod_name=vsd220
But yeah...Acer hasnt
Perhaps this should get the ball rolling? It's funny how the US site doesn't have that
edit: wow looks like they even provided flashing tools and instructions...I just hope that this doesn't brick my unit (since its Acer not Viewsonic)...anyone else willing to give it a try?
hello peopleI need your help without any information someone deleted all my files tf101g
TF101G entering recovery mode with cwm
cwm 5.5.0.4 but this does not allow me to upgrade from external sd card. I tried to flash from w7 with some programs, wheelie, nvflash, tubuntu, oneclickrecovery among others.
adb shell
exec ' system bin sh' failed no such file or directory 2
pushing something. permission denied
NVFLASH
rcm version 0x4 command send failed (usb write failed)
can someone help me
Since you have a TF101G, NVFlash is not an option.
Does your device show up as an ADB device in windows when you boot to recovery?
Another thought- if you hold VOL DOWN and POWER for 12-15 seconds and release when you see the white text (and don't hit vol up to enter RCK), does it boot up?
If so, you just have a recovery bootloop and can boot using this method until we fix it.
If not, back to my first thought - if it shows in the device manager, update the drivers using the naked drivers 0.72.
Then try typing "adb devices" at a command prompt and see if it is recognized via USB.
If so, push your firmware using the following:
adb push firmware.zip /sdcard/
If that succeeds, you should be able to flash the firmware from recovery.

Try fixing permissions in CWM. I think it is under advanced.
i have a slight problem. i grabbed the ubuntu touch alpha and went in to recovery, loaded it (according to thread instructions) but ended up with a bootloop.
in the end i thought "lets just put another rom back on for now" and then realised i had deleted the other rom from the sdcard! so i'm stuck with it not booting in to ubuntu, and not able to get another rom on as it doesn't boot in.
can i connect to the internal sdcard area myself by plugging the usb in to the pc or something?
i have twrp loaded as recovery
thanks
ah, TWRP adb sideload to the rescue!

The issue, Superwipe wipes the internal /sdcard/ and also this is where it flashes from.
You need to boot to recovery and then use ADB to push files to the sdcard.
If you have never used ADB, it can be a bit daunting.
First, you need adb from the Android SDK. It is a big file for the few you need. I have a copy of the relevant ADB files here: https://db.tt/b9dQ6xzp
Unzip this to c:\adb folder on windows. If you are using Linux, it should already have adb in the /usr/bin/ folder.
Next, you need the Universal Naked Drivers: http://forum.xda-developers.com/attachment.php?attachmentid=1934814&d=1367674531
Unzip these to c:\universal_naked_drivers
Boot to CWM and then plug in your USB cable. It should show a new device found. It may find 2, an MTP and then there should be another either Unknown device or an Android ADB device. Right click and update the driver. Be sure to search for driver, then tell it you want to pick from a list. Hit the Have Disk button and then hit the browse button and browse to c:\universal_naked_drivers and hit OK. It should show you a driver to select and hit OK. If you are using Win 8, there is an additional step that is required to used non-signed drivers.
Once the driver is updated, download the zip file you want to flash on your PC. I assume it is a ROM.zip file for this example. Place this file in the c:\adb folder and call it ROM.zip (can be named something else, but this is what we will use for this example).
Now, open a command prompt and execute the following:
Code:
> [B]c:[/B]
c:\> [B]cd c:\adb[/B]
c:\adb> [B]adb devices[/B]
It will probably say some messages about the daemon is not running, restarting adb.
Then it should show a list. There should be some numbers followed by "recovery"
If no devices are shown, check that your ADB device is showing in the Device Manager.
Once you see it in the adb devices list, continue:
Code:
c:\adb> [B]adb push ROM.zip /sdcard/[/B]
successfully pushed xxx bytes
c:\adb>
At this point you should now see the ROM.zip file on the internal storage in CWM to allow you to install it.
Choose to install the file then reboot (not to recovery). You have to let it flash the file (progress bar will show). Once the screen goes black and the progress bar disappears, it should now boot to your ROM..
If your ROM requires a custom kernel and/or GAPPS to be flashed, use the same procedure to push your kernel.zip and GAPPS.zip to the /sdcard/ directory.
