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Sorry, was using outdated adb.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.

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?

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!

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?

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)

E:Can't open /cache/recovery/last_log
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?
Hey folks,
I´ve ran my MZ601 xoom on EOS builds over the last 1,5 years.
Obviously its unlocked and rooted. Currently its running CWM Recovery 4.0.0.4
Now I want to go back to stock to install the latest official updates to get the updated drivers for the UMTS radio/modem module.
After that I want to unlock and get root again to use any of the lastest custom Roms again.
Switching to a touch based recovery would be nice too.
I surfed around a bit and I´m rather confused which steps I need to perform in order to do this.
I guess I need to remove root and lock the bootloader again before I can install official updates ?
Could someone please toss me in the right direction? Maybe some step-by step list?
You'll presumably want Build H.6.1-38-1 for Retail Europe from here.
Returning to stock:
Extract the files from the link above to your adb/fastboot directory if you have one. If you don't have one I've uploaded them for you here.
Connect your Xoom to your PC then open command prompt from your adb folder. (Hold shift > right click on adb-fastboot folder > click Open Command Window Here)
Type adb devices and hit enter, if no devices are listed then ensure USB debugging is switched on in Settings > Development > and tick USB Debugging, then try again.
If it still doesn't appear then download Motorola USB drivers here and try again.
If fine then run:
adb reboot bootloaderThen run the following to flash the stock image:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock
Flashing userdata.img is going to remove all your files so back everything up first.
This should unroot your Xoom anyway, not entirely sure if the lock is required to receive updates, but it's simple to unlock again.
Once booted and through initial setup you should receive several over the air updates. (I believe the stock image is Android 3.2)
Unlock:
Connect your Xoom again and open command window in the adb-fastboot folder as before.
Run:
adb reboot bootloader
fastboot oem unlock
fastboot rebootYou'll now be unlocked.
Install Touch Recovery and Root:
Next download ClockworkMod Touch recovery from here, rename it to just recovery.img for simplicity, and copy the image to the adb-fasboot folder.
Download Xoom Universal Root from here.
Copy that file to your sdcard.
Then run:
adb reboot bootloader
fastboot flash recovery recovery.img(assuming you renamed it)
Once verified, reboot by holding Volume up and Power. (Keep connected to PC and keep command prompt open)
Important: When you see the Motorola logo wait about 3 seconds and hit volume down. You should see 'Android Recovery' in the top left corner, now press volume up to enter recovery.
From recovery go, Install zip from sdcard > choose zip > and select Xoom-Universal-Root.zip
Important: After the root flashes do not reboot.
Run:
adb remount
adb shell mv /system/recovery-from-boot.p /system/recovery-from-boot.p.old
adb shell mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.oldThen select reboot in ClockworkMod recovery and boot as normal.
If you are unable to use adb in recovery, then you can enable this through Windows by doing the following:
Whilst in recovery and connected to your PC, open Device Manager, find your Xoom, usually under 'Other devices'.
Then right click on your Xoom > Update driver software... > Browse my computer for driver software > Let me pick from a list of device drivers on my computer > Pick your Xoom (either one if there's two shown)
Windows should confirm the driver installed then adb should work in recovery.
Finally, run:
adb reboot recoveryIf ClockworkMod touch recovery is still there then all is good!
Hopefully I've made sense! Any questions, just ask.
Repeat of downloads:
Download Motorola USB Drivers (Device Manager) here.
Download ClockworkMod Touch recovery here.
Download Xoom Universal Root here.
Wow, what a detailed guide
Thank you sir
No problem!
Let me know how it goes, hopefully shouldn't have any problems.
Resetting worked great :good:
Right now I´m in an OTA marathon
all that unlock, root and recovery stuff sounds familiar so I don´t expect any problems.
Thanks so far :good:

Ok, so this is not working
after I flash touch recovery and do thta reboot thing I can enter touch recovery, thats fine.
Flashing universal root, fine.
THEN,
adb remount
adb shell mv /system/recovery-from-boot.p /system/recovery-from-boot.p.old
adb shell mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.old
gives me error since in recovery mode there ist no adb connection
Whatever when I choose to reboot the system, recovery warns me that it will get overwritten by boot and ask me to disable this.
Shall I do this?
EDIT: Nevermind, I decided to be a little brave and just confirmed that message.
Now touch clockwork seems to be persistent and I´m a happy Xoomer again
Sorry, I had meant to reply during my lunch break.
Edit: Realised the time on the second of your posts, so wouldn't have been much help on my lunch anyway
Well I believe I just learned something new!
Either that or I'd forgotten it asked.
I assume it disables the action rather than deletes those files.
My method was just so you can use the reverse rename in future to re-enable the overwrite on boot.
In future, not that you'll necessarily ever need this information, you can enable adb in recovery through windows by doing the following
When in recovery and connected to your PC, open Device Manager, find your phone, usually under 'Other Devices'.
Then right click > Update driver > Browse my computer > Let me pick from list > Pick your phone (either one if there's two shown)
Should confirm driver installed then adb should work.
I didn't include the above previously as I couldn't remember having to do it personally.
Glad to hear all is well though!

Im going to guess that you have CWM Recovery installed ?
If yes, that is likely the reason for it not booting
You'll need to put the TF into APX Mode (Volume up & Power while connected to the PC > USB)
Nothing will appear on the TF screen, but the PC should recognise it

You need adb from the Android SDK. I have a zip of the files you need here: http://db.tt/b9dQ6xzp
Unzip these to c:\adb\
Plug your tablet in using the USB cable. Your computer should detect a new device. Update the driver with the Naked Drivers 0.72 ADB driver found in the Dev forum (I think it is on page 2 of threads). If you are running Win 8, there are some extra steps to allow you to use this driver.
Once your devices shows in the device manager as an ADB device, open a command prompt and type the following:
Code:
c:
cd c:\adb
adb devices
At this point, it will probably restart the daemon and then it should show a recovery device. If it does, you can proceed. If not, check that your cable is good, and that an ADB device is showing in the device manager.
Grab the ROM of choice and any GAPPS and kernel that you want to move over to your device. Put them in the c:\adb folder. They will be referred to a ROM.zip, GAPPS.zip and kernel.zip going forward.
Execute the following:
Code:
adb push ROM.zip /sdcard/
adb push GAPPS.zip /sdcard/
adb push kernel.zip /sdcard/
Note there is a space between the zip and the /sdcard/. If you omit this space it will not work.
After each time the "adb push" is executed, it may take up to 10 minutes to push the file depending on how big it is. Just be patient until it says it was pushed successfully.
Once this is done, you should see these files in the internal memory of your device when in recovery.
thanks! got it to work.
Update: When you flash the recovery and supersu files make sure to have the remove encryption file on sd card aswell and add it to the list and flash and if you hang at boot screen.. boot into recovery and wipe cache.. reboot.
WINDOWS USERS ONLY.... USE AT YOUR OWN RISK
Make sure you have the proper drivers and make sure you have a real good usb cable... This rar has the usb drivers and the files already in the folder just drop onto desktop and run cmd.exe
Files Needed: http://www.filedropper.com/nocturnaladbfastboot
http://www.filedropper.com/removeencryption
DO NOT FORMAT SYSTEM!!!!!!!!!!!!!
Make sure you are in bootloader or this will not work..
Key combo to get into bootloader or recovery via hard keys.
power off
volume up + power = recovery
volume down + power = bootloader
from bootloader you have several choices to boot, just pres volume down to choose, power to select.
1. To make sure you are connected run command (adb devices) enter
2. Once you see your device run command (adb reboot bootloader) Then..
3. Run command (fastboot boot boot.img) wait for downloading dialog...
4. Then run command (fastboot flash recovery twrp_recovery.img) and make sure you have the proper files on sd card.. i put all files in the folder on my sd card to make sure...
5. once the screen says okay on tablet.. push the vol down button until you see recovery mode and then push power to start twrp recovery..
6. Once in twrp flash SuperSU246.zip and recovery.zip remove_encryption.zip then reboot... you should have root on reboot:good:
Instructions
I think I understand your instructions but I have a few questions.
Am I typing all of the commands on my pc? (- SuperSU)
Step 3 has “Run command “(fastboot boot boot.img)” I see 2 files and so those are two separate commands to run correct?
Step 4 Then run command (fastboot flash recovery twrp_recovery.img) and make sure you have the proper files on sd card.. i put all files in the folder on my sd card to make sure... Again is this 2 commands to run? I see the twrp_recovery.img file but no fastboot flash recovery file?
In step 4 should I be using theses 2 commannds;
fastboot flash boot boot.img
fastboot flash recovery recovery.img

run them just as there posted make sure all files on the sd card and you should be fine..
Thanks for your reply. Those commands are run on the PC in the cmd window right? and I copied the files in the directory to my SD card I installed on the nextbook should that be a problem. Shoul this be the SD card or internal memory? I didn't run the commands the way they were written last night & didn't have success. I am getting hung up on 3. Run command (fastboot boot boot.img) wait for downloading dialog...
My pc and tablet are seeing eachother but they both say waiting, I don't think my files are being seen.

Make sure you uninstall and reinstall the usb drivers in the folder and run the cmd from the folder and if still nothing try a new cable and usb port... when you run command adb devices do you see your listed as numbers and some letters?
After the adv devices command it gives me; listed devices YFGV0815002950 device. That should be the tablet, it’s the only thing attached w/usb & it also shows up in explorer.
After the adb reboot bootloader cmd the tablet reboots into bootloader with “Fastboot CMD WAITING “ at the bottom of the screen.
After the fastboot boot boot.img cmd my pc cmd rompt says <waiting for device> and my tablet stillhas the Fastboot screen mode & FASTBOOT CMD WAITING at the bottom of the screen
That is as far as I get. I copied all of the files in your download link in the .rar format and to a directory on my internal tablet storage. It seems like the tablet is waiting for a file but I don't understand why.

there is a problem after you boot into bootloader i had the same problem for days.. i just played with cables and drivers use the ones inside the folder they worked for me...
I'll keep trying. It has be the drivers.
I followed these directions to a T, but for some reason the device can not read the SD card while in recovery. Any clues as to why this is happening?
So I was online shopping for my first tablet when I came across this thread. . . It led me down to the local WALMART and I picked one up. I successfully completed the process, or so I thought. I went to reboot after flashing everything, and twrp says " no OS installed! Are you sure you want to reboot?"
What did I do wrong?
I have tried several times to download the remove encryption file must be a bad link or something. Is there another download site or can someone send to me plz
Nvm I ran it over with my car because I couldn't get the download link to work. If anyone wants it for parts send me a message. Its brand new only been used maybe 2 weeks. The most wear and tear on it was my Buick regal hitting it at about 45 mph in a pissed off rage. don't think all the insides are smashed tho. Possibly a good fixer upper
Is this fastboot and adb custom versions?
I have adb and fastboot in my path (runable from anywhere)..
ADB says the version release is the same number.
do I need to use your versions for the tablet?

Copied the two zip files to both a 4gb fat32 formatted microsdhc
and internal storage via MTP to the device then ran ADB 1.0.32
and rebooted to bootloader. (adb finds device fine)
fastboot devices reported device number fastboot.
flashed TWRP in package you uploaded yesterday.
it says both internal and external cards are empty?
internal card has files that the manufacturer put there,
but TWRP can't see them?
What am I doing wrong?
Any ideas how to fix?
log says 'unable to find crypto file'
and it couldn't mount /data or /storage filesystems
>>>
installed TWRP3 that allowed the installs although it still
could not open /data. It did find the external card installed
from there.
I am guessing the forced encryption made /data unreadable.
hopefully now with the encryption removed the /data
partition will be readable.
>>>
I reran recovery to check and log now has no failures!!!
I'm guessing the changed boot.img fixed the issues it was having.
*smiles*
cant get files. takes me to a site to sign up. can you dropbox link them please?
I just won this tablet in a contest. Anyone have the remove_encryption.zip file? I managed to find all of the other required files but none of the links in this thread work anymore.

This guide is meant to less techie people, and written in detail. Please don't mind me if I overexplain. If you have any questions, feel free to comment them.
Also, I am not responsible for anything you do to your phone; you assume your responsibility for anything you do because of this guide.
Scenario:
So, lets say that you tried to flash an zip file on your android using sideload, but the zip required another file to be in the same directory as it, in order to work.
After flashing the zip and getting an error, your phone may not get pass the logo of the brand and be soft bricked.
Also, you formatted your external sd as internal, and cant access your usual location with files in the recovery.
In this case, don't worry, as I'm here to help you unbrick your phone without reinstalling the rom.
Things you will need:
your phone
a computer connected to your phone with an usb cable
the proper drivers for your phone
a custom recovery like cwm or twrp installed on your phone
probably root, although I'm not sure
and finally the adb (android development bridge) utility
Where to get a custom recovery?
- https://www.xda-developers.com/how-to-install-clockworkmod/
or search on xda under at your device's forum
Where to download adb from?
- https://forum.xda-developers.com/showthread.php?t=2588979 (this one comes with the drivers)
- https://dl.google.com/android/repository/platform-tools-latest-windows.zip (just the adb files)
So lets get started:
First, get your phone into Recovery mode (on samsung hold power button volume up and home button), and connect it to your pc with a usb cable.
Open ADB by shift + right clicking the folder platform-tools in witch it is located. Click on "Open Command Prompt window here" or "Open Powershell window here" (depends on your windows settings).
You need to find a location on your phone that is accessible through the flash zip menu from your recovery. (from sdcard / from sdcard1 or whatever your external sd is called)
In my case, i could get to see folder 0 and obb from "flash zip from sdcard".
To find a suitable folder:
In the window, type
Code:
adb.exe shell
if you opened cmd, or
Code:
./adb.exe shell
if you opened powershell.
This will open a terminal that will run commands on your phone.
(Now you can type commands in the cmd window that will be run on your phone.)
Type in
Code:
cd /sdcard/0
to go to the main sd card location that is accessible in recovery when you go to flash a zip from there. (if you can get to another folder where you could a flash a zip from, change the location to that place)
You can use here the command
Code:
ls
to view objects in the folder you are in.
After you are done, type
Code:
exit
to exit.
To solve the soft-brick, you need to reflash the zip, but with the files it needed in the same directory.
Type in the ADB window
Code:
./adb.exe push "location of the file you are sending" "location of the folder you are sending to (eg. /sdcard/0)"
if you are in powershell, or without the ./ if you are in cmd.
Use this until you have sent all the files needed for a successful flash.
Then just use the "flash zip" utility from your recovery with the location you have sent the files to, on your phone, to complete the flash, and solve the half-brick.
Restart your phone and you should be good to go.
