Important Update on Dec 2, 2011: Please do not update to Vizio Update 1.5. This will remove the root as well as disable this hack. According to user felixand in this Post (confirmed by me). You can use Titanium Backup to freeze the Vizio Update Service until a new way arround this is found.

Do not use AnTek Taskmanager to freeze it, or you will be bricked.

New rooting method for latest honeycomb rom HERE thanx to [MENTION=1854196]skinnyquiver[/MENTION]

Hi, i had a hard time to root my vizio vTab because i was not able to get adb access. Since there are other threads in here that have howtos but none worked for me, i thought I'd give a full and easy to follow guide to do it.

This thread is intended to reflect rooting methods for multiple os versions, but at the moment only contains instructions for win7 64bit, as i had no dice to get adb tuning on my vista 32bit system. If anyone has rooted this tablet using a different os, please write up a howto as an answer in this thread and i will link to your post in this linklist:

Rooting under this Operating Systems:

Windows 7 64bit

Windows 7 32bit (above tutorial is working)

Windows Vista 64bit (please write a guide)

Windows Vista 32bit (please write a guide)

Windows XP 64bit (please write a guide)

Windows XP 32bit (please write a guide)

Linux (please write a guide)

Mac OSX (guide by rprr)

Finally i want to add a chapter for after root goodies, please give suggestions on what you did and think others could need this.

What to do after Root

here a collection of things what you can do with root access, this list will be extended with your suggestions when they come in

Titanium Backup

a tool to backup all your apps and system data for easy restoring

Auto Memory Manager

adjust your autokiller values, my recommended settings are somewhere bitween mild and agressive:

FA: 6MB

VA: 12MB

SS: 16MB

HA: 31MB

CP: 48MB

EA: 63MB

set vm heap size

Use RootExplorer or similar to edit /system/build.prop, there add the line

dalvik.vm.heapsize=48m

This will also give a little speedboost to the system

enable ADB in Recovery

I am not sure, but mild could still be too low, as vm.heap_size is set to 64mb, which i guessis the ammount of ram the system allocates before an app starts for its vm.

Not yet, rprr is currently trying to get clockworkmod recovery to work, so we can use update.zip files. After that i am pretty sure the cooking will start. Without it we would be able to use adb to install roms, but clockwork mod is way easier.

I wanted to get it done before that nasty update came and closed the exploit.

I have a Vista 64bit and your instructions, pda net drivers, modded doom file did the trick!

I froze Vizio update with Titanium for now. Will that keep me safe from the nasty update?

Yes, but you wont get any updates to the system until you unfreeze it. Except if we get a custom rom.

alright guys... noob here... just got my vtab about 2 weeks ago, my first android... give me some quick read about "why's" of rooting it.

Completely familiar with jailbreaking my iphone, Cydia is an awesome resource (as well as Installous)... is there such a similar community of developers for 'droids?

I'm still at 1.4, so as long as it doesn't automatically take 1.5 without asking, I'll deny any upgrades until I hear back...

thanks!
[Android Software/Hacking General [Developers Only]] FadeFx:
Firstly with root you can disable update service, which gets annoying after a while if you dont want to update to 1.5. Also you can run applications that require root to do certain tasks, like sync the system clock with a timeserver (clocksync from market) or change the mountpoints of your sdcard and even more.

I was just thinking if you got root can you change the number of ur build version so instead of reading it in the info 56 it will read it 57 and maybe by this way we trick the system to get the update to 2.0 or 3.2.1 honey comb ...... I already updated and failed to pull the update but honeycomb is cool ...

---------- Post added at 03:15 AM ---------- Previous post was at 02:46 AM ----------

I found another thing in the update you can move app to sd ... try this out for who updated the tablet .. go to settings and on "storage" make the default storage location ... micro sd ... instead of tablet ..
[Android Software/Hacking General [Developers Only]] dandrumheller:
Just to be clear, you are suggesting I edit my current build.prop to indicate that I have the 1.5 update, thinking this will trick the updater into grabbing the honeycomb update. Not a bad idea.

Edit: has anyone tried the process I attempted with the 1.5 update? tried modding the updater script in 1.5 update to allow it to be flashed over 1.4 from cwm without losing root? Is there a copy of the 1.5 update kicking around somewhere?

Edit 2: can someone on 1.5 post their build.prop info if you can get to it, or at least build info from the about device menu if you can't get to build.prop. I'll need that stuff if I'm going to try the build.prop mod to try to get the 2.0 update. Thanks
[Android Software/Hacking General [Developers Only]] rprr:
It's been a while since I posted. Does updating to 1.5 for those with cwm recovery preserve the cwm recovery partition. If so maybe after update boot to cwm recovery and try to put an su binary via Adb access or a simple update script.

Edit: can anyone post the updater script from the 1.5 update.

[Android Software/Hacking General [Developers Only]] theFredS:
They did fix the sdcard issue. In settings you change the default storageto the sdcard. It will then move everything in the fake sdcard mapping over and restart your tablet. Afterwards go to Manage Applications and each app that you want to move and that doesn't have a checkmark already next to it will have a "Move to SDCARD" button.

Then your done.

Oh sometimes after an app geta updated by Google Market(Now Google Play) will need the move to sdcard button reapplied. Its easy to see if its needed because the checkbox will be unchecked again afterwards.
[Android Software/Hacking General [Developers Only]] rprr:
Thanks for posting this. It does appear that the recovery partition (with CWM) is preserved during the 1.5 update. If so, then it should be possible to root again for those with CWM recovery via a custom update.zip containing su, superuser etc. after the 1.5 update is done. I have not done this yet.
[Android Software/Hacking General [Developers Only]] dandrumheller:
If you are able to put together a flashable zip to do this, I'd be willing to give it a shot. Guess it's time to install your CWM recovery! :-)
[Android Software/Hacking General [Developers Only]] FadeFx:
I guess it should even be possible to build a cwm zip containing the full prerooted via 1.5 or even the 2.0 firmware as soon as we get hold of it.

[Android Software/Hacking General [Developers Only]] dandrumheller:
That was kind of my original thought, but I don't have the knowledge (yet) to pre root the image. Do you guys know of a guide for doing this somewhere? Do we simply need to add superuser.apk and su? Mess with bootloaders? Something else?

If we can do this with the 1.5 that we have to maintain root, then we should be able to repeat the process with the 2.0 update...

how to get to root directory with out root

hi did any body try to use "es file explorer" to grab the update file because in settings there is an option to enable up to root directory. after i check this option i can get to the root folder and open cache but it empty. i already updated to 2.0
[Android Software/Hacking General [Developers Only]] rprr:
IMO I would not mess with the existing Vizio update as I believe the bricking possibilities could be high if you mess up. I would rather have a simple update.zip containg the su and superuser.
[Android Software/Hacking General [Developers Only]] dandrumheller:
Thanks for the input rprr -- that said, what do you advise? Install CWM and then run the 1.5 update and see if I can still get into CWM? Will your CWM flash allow ADB in recovery at the moment, or do I need to do the ADB in recovery mod as a separate item?
[Android Software/Hacking General [Developers Only]] rprr:
From the following thread at androidtablets.net

http://www.androidtablets.net/forum/showthread.php?p=194683

it appears that with the cwm recovery the update will be downloaded but not installed. What I don't know is if it is possible to mount the cache folder and install the update using cwm. If so that would indeed preserve the cwm folder.

The cwm hack does allow adb access in recovery boot. The separate adb in recovery mod is not needed.

At the moment I am unable to try all of this.

Edit: I wonder if just having the recovery with adb hack might be enough instead of the full cwm recovery. It maybe that this will allow the installation of the 1.5 update. Though with just the adb recovery it may require reinstall of the cwm in order to install su and superuser more easily.
[Android Software/Hacking General [Developers Only]] FadeFx:
I am not sure if an update would work with cwm recovery as the updater service will most likely not cooperate with non stock recovery.

Hard bricked? What did you do? Just flash the update.zip in cwm?
[Android Software/Hacking General [Developers Only]] rprr:
Real hard brick. Nothing.

I unfroze the update. Downloaded the 1.5 update and then it booted into CWM. It first did not install as Signature Verification failed. I then toggled Signature verification off in CWM and then it seemed to install ok. After the install, it rebooted but the bottom button lights came on in landscape mode and stayed on for a long time with no V Logo for almost 5+ mins. I then hit the power switch again but nothing happened. Nothing lights up. :(

Sorry about the bad link - it was supposed to be to a post you made on androidtablets re: removing essentially everything but /system from the update.zip for 1.5 update and then flashing that.

As I said before, I don't know enough about how this all works to know how to set that up myself yet. Is it possible to add su binary and superuser.apk to the /system in the update.zip and flash it from cwm? Does su binary have to go somewhere else? So yes, Fade is correct.

I now would guess doing the same with the 2.0 update would not work, as we would not have the kernel/uboot/whatever else is needed for change to HC.

Please don't hesitate to tell me if I'm way off base here - I am basically brainstorming possibilities - I don't really know what I'm doing :D

having to send a vtab back to Vizio for the usb port failing and it is currently rooted. I've searched (maybe not enough though) on how to remove root and restore it to factory. Outside of a factory wipe through the boot recovery, I can't find anything to verify that this is all I need to do.

Any suggestions?
[Android Software/Hacking General [Developers Only]] FadeFx:
A factory reset is recommended anyways, but it wont unroot your tablet. If you did not install cwm recovery you could let install the update to 1.5 firmware, but beaware that you wont be able to root it anymore when you get it back. But this is most likely the case anyway, as they will update it to the latest firmware after repair. If you have cwm installed, you need to install stock recovery before you go for the update.

[Android Software/Hacking General [Developers Only]] theFredS:
Quick question about the 2.0 update

Hey guys, since I'd lost root a long time ago, I went ahead and took the Honeycomb update. In settings there is an option to change the default install location to the SDCard proper. It moves everything from the internal storage that was originally partitioned as /sdcard and /mnt/sdcard to the real sdcard mounted as "external" from within the virtual sdcard partition.

I noticed two things after the move and reboot necessary to change the tablet over to using the sdcard properly.

First the space originally used for the virtual sdcard isn't recovered, what I mean is, Vizio doesn't resize the internal memory partition to use the now unused space originally used by the /sdcard mapping, which really sucks but isn't the reason for my post now.

Second, and correctly me if I'm wrong. I don't believe the API, and I could be wrong, defines a way to script the changes. I know in Linux its easy enough to do, but don't you need elevated privileges to do it? Whenever I've ever written a bash script to apply changes, I needed to sudo the commands. So I'm wondering if Vizio has a hidden and probably renamed su or sudo somewhere in the new update to allow them to script the changes, and if they did, could we use it to reroot our tablets on the Honeycomb update.

Just knocking around ideas.

theFred
[Android Software/Hacking General [Developers Only]] dandrumheller:
What's your take, day to day usage wise, on rooted 1.4 vs HoneyComb? Is the update worth losing root? To me, CWM isn't really worth too much as we don't have multiple ROMs to flash. The performance tweaks available (on rooted 1.4) are nice, but how does the HC performance compare?

Basically I'm trying to decide if the update is worth losing root for. From where I stand, it seems like it might be...

Thanks.
[Android Software/Hacking General [Developers Only]] DCRocks:
I was wondering the same thing..

Two main questions.. after the update to HC, are you able to side load apps?

Also, I take it after the update to HC, you lose the ability to backup and restore game data, correct?

These are the two items keeping me on rooted 1.4
[Android Software/Hacking General [Developers Only]] dandrumheller:
saving game data wouldn't be a big deal for me (don't really use the tablet for gaming) but sideloading would tough to lose for me, given that (at least in the past, though maybe not with HC?) there are quite a few apps that didn't show in the market that I use. I think I recall seeing somewhere that USB debugging is usable in the HC update - if that is the case, I would think that at least the sideload wonder machine from AC would be an option here if there was no other way - but since I've never used it, I very well could be wrong...
[Android Software/Hacking General [Developers Only]] NComrade:
Thanks, that is what I figured I could do. I had only rooted to preserve the ability to root in the first place. So I'll just let the updates run, play with gingerbread for a few days and send it back when the replacement gets here next week. Who knows, by then we may a method of rooting the latest firmware. :)

I did get a replacement. Came with .57, so my rooting days are over. Just waiting for it to get the HC update.
[Android Software/Hacking General [Developers Only]] godsponge:
I am able to turn on the option to install non-market apps and use the amazon appstore on mine with honeycomb. As far as I know you can't do proper backups with a non-rooted rom.

The main draw was the tablet Google apps for me. The full sized gmail app was worth it by itself in my opinion. Of course I never had root so take my opinion with a grain of salt.
