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.

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.
[Miscellaneous Android Development] admisi:
Sorry, was using outdated adb.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?
[Miscellaneous Android Development] admisi:
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.

Here is a script to reboot recovery mode; from your Android VSD220.

********* script starts here

I used Scripter Ver. 1.8 It work find. Don't forget to flash the right recovery.img and install su.zip. If you don't the script won't work.
[Miscellaneous Android Development] n1gh7m4r3:
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.
[Miscellaneous Android Development] sk8tingusmc:
I didn't know 1.3 was available. Is this a recent firmware? I checked a couple weeks ago.

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?

​

5. At the Command Prompt type "adb reboot bootloader" and hit enter.

The screen will turn solid black
​

6. 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

Rom Version and work in Linux?

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!
[Miscellaneous Android Development] swiss420:
There are a universal ADB Drivers for Windows.

Universal Naked Driver for example.

http://xdaforums.com/showthread.php?t=1161769

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.
[Miscellaneous Android Development] LoveMyAndroid2010:
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:

Model number

DA220HQL

Android version

4.0.4

Kernel version

3.0.21-00003-OMAP-Android+

Thanks for the help!
[Miscellaneous Android Development] swiss420:
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?
[Miscellaneous Android Development] LoveMyAndroid2010:
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.
[Miscellaneous Android Development] LoveMyAndroid2010:
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!
[Miscellaneous Android Development] nee_vak:
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 mount /cache/recovery/log

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
[Miscellaneous Android Development] nee_vak:
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?
[Miscellaneous Android Development] nee_vak:
Looks like I accidentally volunteered myself when I ran the batch file trying to see if there was a match.

After installing the 4430 omap driver, it started installing without any prompts, because I had adb drivers previously installed (skipped that step).

It kind of freaked me out, since I thought I just bought myself a shiny brick.

Thankfully it booted up just fine...with Viewsonic boot animation and all. Just as suspected, the ROMs are interchangeable.

I'm pretty sure with the OMAP flash tools available, the device could easily be restored from a hard brick.

The ROM is fully rooted, no superuser app needed.

Only drawback, there is no play store included (but google play services is)... I'm pretty sure flashing the 4.0.4 gapps zip should take care of that.

With the current state of the OS, I'm pretty satisfied with the device. Sure its not running JB, but its close enough.
[Miscellaneous Android Development] nee_vak:
Hrmm, recovery is still bunk. Didn't install gapps when I tried sideloading it.

Turns out all you need to do is copy a playstore apk to the /system/app folder and just set the right permissions.
[Miscellaneous Android Development] gersto:
finally!

Well it's about time!

But i guess we should take it as, "you are on your own. we (viewsonic) are not going to update this anymore!"

WE bought about 5 of these for my job and the response on these is fairly jerky (1 is my test bed unit since our dept paid for it). They are useful for what they are intended, and cheaper than a full on PC with mouse/keyboard/monitor for that intended use.

But maybe now i can finally use some scripts to get a performance boost, and remove some apps
[Miscellaneous Android Development] ritdaw:
I rooted ours yesterday for a kiosk project I'm working on. Helps to remove some of the apps but I'm sure a performance boost would come in the form of some custom roms. I doubt there is anyone working on any though. :(

There are some scripts out there like supercharger.

How can I go about booting an image off the SD card? I read up on the img writer, but I don't have an image to write (no roms factory or otherwise seem to exist anywhere online, the viewsonic/uk link above was pulled and I have no nandroid backuo).

The 1.1 update hosed my android on the vsd220, so i've spent about 6 months trying to fix this off and on. I finally got to cracking on it hard the past week or so and after a whole lot of troubleshooting i finally got fastbook working and loaded the CWM flash. However, being uber brilliant I saw the factory reset option when CWM started up and thought that might reset this thing for me, however it appears that it turned off USB debugging in the process so now I can't even get to it via ADB. My device just starts up to a blank screen with a short message saying "Waiting..." appearing on cold-booting.

I have tried everything to get this thing back into recovery, however since it has no 2nd button I think i'm SOL. I don't know if the CWM is stil leven loaded, and if it is, I don't know how to get it into fastboot or adb enabled mode without first getting access to the device. Did CWM add any alternative methods for accessing adb or is there any other was to get USB debugging re-enabled?

I have tried:

1. Creating a bootable SD card (with just a copy of CWM on it, since i have no full rom available).

2. plugging in a sdcard, USB flash card, and USB mouse

3. timed button pressing and button mashing on the USB keyboard to force an error or other method to jump it out.

Thing i am going to try now:

1. more reading on SD booting and trying to find some kind of image

2. hooking up ethernet and seeing if it does anything else (dhcp? exploitable services? etc)

3. if i can't do any of those i may contact viewsonic again

I'd love to at least get the touch feature as an external monitor fixed so I can do more than stare at a black screen.
[Miscellaneous Android Development] oncouch1:
Any luck? I just hosed mine! I hit factory reset in cwm bay accident (dumbass). Needless to say I am starring at the same screen as you. I opened the unit up and see it is a Hannstar MV-7 but there is no hard reset button as found on some cheap tablets.

I will open it again as I did not look for volume control pads (may help if they are there).

You still can use it as an HDMI device so not all is lost :^)

Found the viewsonic rom, now to figure out if I can flash it!

Useful rooted rom?

Not sure when it was added, but ViewSonic posted the rooted OEM IMG with a full guide/walk-through/drivers. Don't remember seeing it there the last time I looked, so I believe it is a somewhat recent addition.

I would link ya, but I'm not pro enough, maybe after another year or two of being a member.

**EXTREME NOOB**

I have an ASUS TF700 unlocked with TWRP installed. I am using Windows 7 64 bit. I am able to get into Fastboot on my tablet.

In trying to follow the nvflash guide, I have no idea where to enter the commands. I tried entering them into cmd but that doesn’t work. Do I need to change the directory? If so, what do I change it to? (This info is not in the guide)

What is SDK? Do I need to install that on my PC first? (This is not in the guide)

I have read that people have installed the Universal Naked Driver. Unfortunately, I can only install one of the drivers from the Universal Naked Driver folder at a time. How are people installing all of the drivers?

I thought this was going to be simple and straight forward, but I am totally lost. I would like to have this taken care of before I start flashing ROMs.

Never mind.....I got it.
[Asus Transformer TF700] vinsontan:
Hi guys, I'm posting this here as I can't seem to find anyone with the same problems as me and I am hoping someone here can help me.

Everytime I run Dolphin Browser (ver. 9.3.1), there is a MASSIVE keyboard lag whenever I want to enter anything in the address bar. The keyboard will only show up after a few seconds (ranging from 1-4 seconds) and when I enter the address, some alphabet inputs will be missing as it was not registered by Dolphin due to the lag. So for example, if I entered yahoo.com, only yo.com will be registered on the address bar, eventhough I typed yahoo.com.

General speed of loading the websites is not affected and is quite fast. It's only when there is a keyboard input involved, then it lags like hell.

I have tried tweaking my Infinity with System Tuner Pro to increase the memory limit of Dolphin browser but it doesn't seem to work. I also have Browser2Ram (as part of Cleanrom inheritance 3.3) but nothing seems to work.

Searching for similar problems faced by other owners of Inifinity also turned up empty so I hope someone can help me on this.

I have a rooted Asus TF700 running on Cleanrom inheritance 3.3 ODEX version, but I also experienced this problem when I was running my TF700 unrooted.

Please help! It's driving me crazy as I'm a big Dolphin fan!

Thanks a bunch!
[Asus Transformer TF700] king231:
Well i'm facing the same on stock. So i guess its time to write to asus.
[Asus Transformer TF700] flyhighx:
I have the same issue with Dolphin as well. I've had it stock and also with CROMI. I have switched to the stock browser which, with CROMI, is so lightning quick and lag free. I also like Dolphin, and still use it for some websites that work better with it or I need Dolphin's add-ons for, but mainly, I use stock and am very happy.

But, no, you are not alone with Dolphin lagging badly with our device.

Odp: [Q] Massive keyboard lag with Dolphin browser

Finally someone else has the same problem as me. This is my #1 issue with everyday use of Infinity. Yes, I could switch to Boat or other brower. But I got used to Dolphin interface.

I wrote about the problem to Dolphin developers twice. They acknowledged it but did nothing about it.

The lag is probably related to the way they programmed Google search suggestions. Try disabling suggestions from Google in Dolphin preferences, the lag will be almost done. All other suggestions (history, bookmarks) will also be disabled.

The problems seems to be as follows. You type a letter. Dolphin looks for search suggestions, displays them, then reads another key, and so on. If many keys are in the buffer, it gets slower and slower. If you type really fast, the keyboard buffer overfills and some keystrokes are lost.

If you use onscreen keyboard, this problem does not occur. With the keyboard dock, you usually type faster. Passing the keystrokes through USB may also account to this. Correct me if I'm wrong.

To sum up: everyone who has this problem, please send a report to Dolphin developers (they have form on their web page). Maybe if more people will report, they will finally do something about it.
[Asus Transformer TF700] king231:
I would strongly suggest you guys to use stock. Its almost bug free and also fast enough. On mine it displays the content faster than dolphin and the page load is faster than dolphin. I have timed the loading of all the websites i frequently visit( yes I cleared all history, cache, etc. and also disabled pre loading) and dolphin took almost 5-10 seconds more than the stock browser to load up the pages. You can even try chrome. Its good after the latest update. I didn't try timing it but its better the previous version.
[Asus Transformer TF700] zhivchik:
It has been brought up before that Dolphin is less optimized for tablets than it is for the smart phones. Might not be entirely the problem with the device.
