[Q] Sideload Script says no device found? - Barnes & Noble Nook Tablet

My Nook Tablet just updated to the dreaded 1.4.1 version which makes sideloading pretty difficult.
I was reading this article which has steps to sideload apps onto the 1.4.1 NT without rooting it, and pointed to downloading this script on the XDA forums which will push the apk onto the plugged in tablet, as long as the apk is in the same folder as the Sideload script files.
So, steps 1 to 5 weren't a real problem but its Step 6 that I'm stuck on.
There is a Sideload BAT script which seemed to run (its disclaimer is that it will only run if it finds an Android device -- which is a clear indication that it could find and recognize that my Nook Tablet is plugged in). It even says C:\Sideload>adb wait-for-device. However, when I try to tell it to install the apk via Command Prompt (I type in: adb install Amazon_Appstore-release.apk ), it returns "error: device not found" .
Just for good measure, I also type in C:\Sideload\adb devices and it returns: List of devices attached .
I'd greatly appreciate if somebody could help me with this--I really have it up a wall and would just like to put this problem to bed. Thanks!

i'm having the same exact problems here! are there any specific drivers to install?

Yep, I was still fairly a noob at this when I first posted but have learned a lot ever since. Here's what you want to do:
(btw, I factory resetted to 1.4.0--you may need to as well):
When it says "no device found", it's corresponding to this command line : adb install whatevernameofapp.apk . I interpreted "no device found" to mean that it does not know what "adb" means in the command.
For it to recognize all "adb" related commands, you have to have the USB drivers installed. Look for tgps_launcher.apk on this link: http://forum.xda-developers.com/showthread.php?t=1354487. That will set you up with having you Nook to accept third party applications + having it on UBS debug mode.
Then, install the drivers (I saw this YouTube walkthrough because it is NOT intuitive and you want to be sure you're doing it right , it's not the way you would traditionally update drivers for a mouse or keyboard; here: http://www.youtube.com/watch?v=ZtGveN7jbzs )
After that, I followed the instructions on this article, made a folder in C:, called it sideload, and also pasted an .apk. Now, when I do the Commant Prompt, it says this: http://img23.imageshack.us/img23/2914/cmdnookadb.jpg . While, the transfer was successful, I haven't been able to see the app on my tablet. Does anyone know where I can find this (data/local wasn't found when I connected the tablet to my PC either, and it wasn't on my SD or so). Is it because I'm still on 1.4.0?
Let me know if you get it working all the way!

I followed all those directions exactly. I had received the No Device Found error. I followed the Youtube directions to add drivers and it seems like I did it correctly. I am seeing the android device on the device manager.
I tried running the script again and got the same error! I'm now stuck!
I had the amazon marketplace already installed and was using it successfully until my nook updated to 1.4.2. I thought I had ES File Explorer downloaded but for some reason I can't find it! So I now I am trying to sideload ES File Explorer this way but it wont work!

0x2080
^ put that in %userprofile%\.android\adb_usb.ini

Can you give me more specific instructions on how to do that?
FYI - I have ver 1.4.2 and I am NOT rooted. I have already enabled unknown sources and downloaded the amazon market. I was installing 3rd party apps fine before the update.

my situation....please help

rooted via ubuntu and have recovery
i tried doing stuff in windows, but it wont install the drivers properly.
SO I NEED HELP!
what do i do to get this to work?
i want to be able to install 3rd party apps and get rid of att bloatware.
i have no idea where to start.
HELP!!!!!!!!!
thanx
ubuntu or windows...
download the Android SDK for Windows
http://developer.android.com/sdk/index.html
install and download ONLY THE USB DRIVERS
open cmd window, connect usb cable, navigate to the <folder>\tools where you installed, ie. c:\android\tools
paste the following into a small batch file, call it anything you want dot bat,
ie. c:\android\tools\yourname.bat
---cut here--
cd\android\tools
adb remount
adb pull /data/data/com.android.providers.settings/databases/settings.db settings.db
echo update secure set value = 1 where name = 'install_non_market_apps';|sqlite3 settings.db
adb push settings.db /data/data/com.android.providers.settings/databases/settings.db
pause 1
adb reboot
-- cut here--
ok i'll try right now
still must be missing something
what setting is my phone on when i plug it in? recovery? or just regular charge only or hard disk mode?
how do i get the usb drivers to work? when i try to install them is says "windows was unable to install your adb". is there something else i need on my pc?
when i run that .bat file it says a bunch of things, but basically says device not found.
please start from step #0.
there is no one place that has every single step we need to do.
it makes it next to impossible to get this to work.

I'm not sure I've ever seen this error come up before by anyone. Saying this is impossible isn't really true since several people have gotten it working, and the information is on these forums. The best thing to do would be to go to the IRC channel and get stepped through it. http://webchat.freenode.net/?channels=#liberatedAria
I'm not quite sure what's up with your ADB install, but you should download HTC Sync from the HTC site, because it includes a driver install. http://www.htc.com/us/support/aria-att/downloads/. Then go through the process in the post above. Your phone should be in the "Charge Only" mode when connected to the computer.

i know it's not impossible, it's just that usually when the people explaining the steps to accomplish this leave out steps that they think is common knowledge/sense, but is not to total noobs.
it would be nice to have a definitive step-by-step guide:
step 1 - root your phone (this was actually really easy with the ubuntu cd)
step 2 - go back to windows and download/install these specific programs . . . (i did not know i needed htc sync, the steps i saw said just to use the sdk and the usb drivers in there to set up my phone)
step 3 - enable debugging on phone, plug your phone into pc and use charge only. (don't we use recovery for anything, i've seen steps about having this open and using the mount /system to do stuff)
step 4 - get the adb usb drivers to install properly (i guess this is my main issue at the moment...is that what is causing the device not found error when i run the .bat file?)
step 5 - copy and paste code into notepad an save as a .bat file.
step 6 - run the .bat file (within cmd? double click on the file? does it matter?)
step 7 - ????
alternate step 2 through whatever - use the ubuntu cd to do everything... (???)

Run the bat file in the cmd window. Once the bat has successfully run you can unplug the phone and you'll be good to go.

so what is the point of the sdk...other than to have the tools folder to run that .bat? so i'm the only one that can't get the sdk usb drivers to work?
and by good to go, u mean i can install 3rd party apps?
how do i get rid of the the at&t bloatware?
There are other threads explaining how to install third party apps and remove ATT bloatware.
Sent from my HTC Liberty using XDA App
The problem with trying to do a step-by-step guide is that things like rooting, removing bloatware, and sideloading apps are all separate processes that require different steps and can be done in multiple ways. Some stuff requires you to be in recovery, some stuff doesn't, and other methods may require additional software. That's why there are specific separate threads that discuss them.
You've rooted your phone already, yay! Now you decide what you want to do next. Remove the bloatware? It's important that you don't lump everything together when trying to figure out what you need to do.
It seems like the first step you need to do is get ADB working and recognizing your phone when it's plugged in. ADB is necessary because it provides all the tools/commands necessary for us to interact with the phone through the command line. Windows is notoriously bad about the USB drivers. That's why the Ubuntu method was streamlined for people so they wouldn't have to deal with it. (Linux and Mac have no such usb driver issues.)

thanks for the reply.
yeah i rooted via the ubuntu disc, but then all the other steps people were telling me were using the sdk, getting the drivers, htc sync, yada yada. via windows. so thats the method i've been trying.
is there a step-by-step guide on how to allow 3rd party apps using the ubuntu disc? or... removing bloatware?
is it the same steps, but you just dont have to worry about the drivers?
The steps listed once you're in the SDK are actually the same regardless of what OS you're using.
So for Ubuntu install the SDK. Steps should be the same, just make sure you download the Linux version. Then you'd open a Terminal window (should be called Terminal in Ubuntu.) Then you should be able to use the same commands/steps you find in the other threads.
Since you've been having trouble getting your phone to connect the first thing to do is make sure SDK can actually see your phone. You should be able to open up your Terminal window, navigate to the SDK folder, connect your phone and then type 'adb devices' in the terminal window. It should then list out your phone as HTXXXXXXXX. X being some numbers and letters. If it does show that then you're on your way.
After that I'd go with removing bloatware and the steps listed in this thread. http://forum.xda-developers.com/showthread.php?t=735255

ok cool thanks a lot!
i didn't even think to go back to linux to try this stuff until today at work.
i'll check it out later tonight after i mow the lawn and eat dinner....priorities...
i tried in windows one last time. it actually found the htc sync drivers (i in/uninstalled htc snyc earlier...i guess thats what did it)
adb devices command finds my phone, but when i try and run that .bat file, it goes through a bunch of things, but basically says:
remount failed: operation not permitted
failed to copy...
permission denied
all those types of things. then it says to hit enter and then it restarts my phone
???
did u try installing HTC sync connect phone to htc sync, then unistall the htc sync software usb drivers should stay behind

My quest to root my Vizio VTAB108 Tablet and how I enabled ADB access

I am new to the Android platform so please excuse any silliness on my part…
Below are the steps I took to successfully allow my Vizio Tablet (VTAB108) to connect via USB using the generic Google ADB driver as Vizio does not include ADB access for the tablet.
History:
I am trying to Root my tablet and from what I read throughout the forum, the easiest steps to root a tablet is using the SuperOneClick method.
Since SuperOneClick requires ADB access and the Vizio does not include the ADB driver (and the generic Google) do not work out of the box I was at a loss to how I would run SuperOne Click.
This article are the steps I took to get ADB access working with Windows 7 x64 and the Vizio Tablet.
I am hoping my steps here can further lead to root access for this tablet.
As an FYI, I was still unsuccessful in getting SuperOneclick to completely run after following these steps, but maybe someone has an alternate method of rooting now that ADB access is available? /me crosses fingers
It would stop at Step #6 at which time I would disconnect and reconnect the tablet. It would contine to step #8 but then finally fail. If anyone has an alternative to SuperOneClick, I would gladly try it.
IMPORTANT:
The instructions below assume you have already put your Tablet into USB debugging mode.
The instructions below assume you are running Windows 7 x64. If you are running x32 versions of your OS, modify the below settings as apporopriate for your OS[/B].
1. Download and install the Google Android SDK.
(Being this is my first post, I cannot post a URL so google the following topic exactly and click the first link):
what-is-adb-and-how-to-install-it-android
2. When you get to the USB driver install you will have to manually modify your android_winusb.inf settings file to allow Windows to recognize your Vizio Tablet using the generic Google ADB-USB driver.
3. Find the "usb_driver" folder in your sdk directory. (Mine was: C:\Program Files (x86)\Android\android-sdk\extras\google\usb_driver).
4. Right-click "android_winusb.inf" and open it with notepad or your favorite text editor.
Under the [Google.NTamd64] section, paste the following:
Code:
;Vizio Tablet
%SingleAdbInterface% = USB_Install, USB\VID_0489&PID_E040&MI_01
%CompositeAdbInterface% = USB_Install, USB\VID_0489&PID_E040&REV_0227&MI_01
then, open a command prompt and type the following:
Code:
echo 0x489 >> "%USERPROFILE%\.android\adb_usb.ini"
5. Right-Click the unknown device in Windows Device Manager (Under Other devices) and manually install the driver for your Tablet.
NOTE: Originally my tablet connected to the computer and installed the regular Windows 7 Mass Storage driver. I had to remove this driver before I could see the device listed under "Other Devices". Follow these instructions if you need to remove your generic Mass Storage driver:
Code:
A. Unplug all removable devices (USB drives, Thumb Drives, SD Cards, Etc...) but leave the Android phone plugged in.
B. Open Windows Device Manager.
C. Select "Universal Serial Bus Controllers"
D. Select USB Mass Storage Device.
IMPORTANT: Click on the details tab and select "Compatible Ids" under the Property drop-down. You should see three items listed under Value. If not, you are looking at the wrong Mass Storage Controller.
E. Select Uninstall Driver
F. Close the window.
G. Right-Click your computer name at the top of device manager and select "Scan for Hardware Changes".
H. Your new "Android Phone USB device" with a Yellow Exlamation mark! will appear under Other Devices.
I. Click on the "Android Phone USB device"
J. Select "Update driver software"
J. Select "Browse my computer for driver doftware"
K. Browse for the location that you have unzipped the android_usb_windows ( Mine is: C:\Program Files (x86)\Android\android-sdk\extras\google\usb_driver )
6. Now test to make sure you can access your device in USB Debug mode:
Type the following from a command prompt:
adb kill-server
adb devices
You should see your device serial number at the command prompt and in Windows Device Manager if everything worked.
drivers
USB Drivers have been posted on the vizio support website for Intel and for AMD. Are they crucial to what you want to do about rooting?

I grabbed those drivers a couple of days ago and could not get Win7 or WinXP to install them with the vtab1008.
I can use adb to interface with the vtab008 (using Linux and Win7), but GingerBreak and SimpleOneClick (which uses GingerBreak) are unable to root the vtab1008.
I've been pestering Vizio about the downsides of the tablet. Coming from a rooted Nook, there are some things about the vizio i really like. It's a nice build at an attractive cost. If I can get netflix and hbo go working, a better remote app and a more logical system of using the sd card, I would keep it. Otherwise it goes back to Costco on the 89th day after purchase.
Agreed

Yes, I agree. If there's no root, the tablet is not worth it.
The drivers worked for me.
I downloaded the drivers from the Vizio site and when I plugged the VTAB into my computer I manually installed the driver. I just used adb to grab a bunch of screenshots.
OP worked for me (without the mass storage issue)
Code:
adb reboot bootloader
just did a true reboot
Code:
adb reboot recovery
got me the exclamation mark and the "Home" button brought me to a recovery screen where it would let me flash signed updates or cache/full wipe the device.
You can get to recovery mode by holding down both volume buttons and the power button. Details
I cant even get the drivers to install. I've did a right click on the .inf file and it will not install. Any Ideas?
Thanks

DL the drivers from the Vizio site. Turn on USB debugging on the VTAB. Plug the VTAB into your computer. When the install driver prompt comes up follow the steps to install a driver from a specific location and point it to the driver you downloaded. The steps will vary depending on the version of windows you are running.

Did you actually get into the bootloader? adb reboot bootloader simply reboots the device for me.
So whats with gingerbreak? No love with it? I thought this thing was rooted already prior to shipping? Hmmm. My bro just ordered one for me and I am curious about getting it rooted. Lets get this thing rooted and overclocked and get it some love. Also, whats the word on honeycomb on this beast? anything?....

Rooting help
I have some coding knowledge, but have never worked on rooting a device. I did not pay for mine, so if anyone has references to some info I can look at about obtaining root then I will work on mine without fear of bricking it.
I have been at this for weeks, to no avail.. tried changing params in Gingerbreak, tried running it under every condition possible, and the only thing I haven't tried is changing how GingerBreak is using the /sdcard/ mount point, as that's where the internal memory is mounted to.. It's a pretty odd move to make, and I don't like having my true sdcard in /sdcard/external. what a crock :/
This tablet has to have a way to be rooted, I tried an older version of gingerbreak 1.1 just kept running, never failed, but didn't root the tablet just kept running, like it was gonna root the tablet, kinda weird, I do know that the bootloader is not locked down, my wife works for vizio, the company gave there employees a tablet for free

Im going CRAZY trying to root!

Heres the deal. I have a MAC with a newly installed hard drive. On my old hard drive I had everything setup with SDK and Adb but that was when I had an HTC Hero. My problem is this: When in terminal my damn computer keeps prompting me for a password but it doesnt allow me to type anything except control C which aborts the program. It never was like that with the old hard drive.
2. Ive dl SDK for MAC unzipped it and saved it to my desktop and my hard drive.
3. When I click on tools it says "adb_has_moved.txt"
4. It says the adb tool has moved to platform-tools/ and if you dont see this directory in your SDK, launch the SDK and AVD manager and install "android SDK Platform-tools and also update my path environment variable to include the platform-tools/ directory, so I can execute adb from any location. What the heck does this mean and how do I fix it. Also how do I know if SDK is installed correctly.
5. I DL some version of eclipse that was recommended from SDK but I dont know how to use that either.
6. I have tried all the root methods shown here in XDA except the on with the Dock since I dont have a dock.
7. Also ADB does not recognize my device and my debug is selected. I cannot get it to find my device.
8. One last question when some instructions say unzipped and move the root exploit to /data/tmp/ is that the file labeled under sdcard/data or is it the one inside the Android Folder listed as "data"
Please anyone help if possible.
let me try that
Stupid question but How do I launch SDK?

Make sure your phone has USB Debugging Mode enabled. Otherwise, adb will not recognize your device.
Check this thread: http://forum.xda-developers.com/showthread.php?t=879701
However, you will have to modify for MAC.
In my opinion the easiest way to root the Photon is still using the dock method. Otherwise, try the One Click Root method (Torpedo) as mentioned above. Then you don't have to worry about issuing all the commands.
I got it done I got it done. What I did was borrow my daughters windows netbook and the one click method worked on the first try. Thanks to all who replied. I will definitely hit your thanks buttons.
Sent from my MB855 using XDA App
im sorry.. my tool was a one click i dint think i needed to give it instructions.. especially teh part of how to run it on your computer... just fyi.. when invoking sudo (to do things as admin/root) on your computer. you are asked to enter in your password.. as a privacy/security feature it will NOT display any characters.. ergo it looks blank...
as you arent teh first one to run into this issue ill add instructions for mac users ( i know anyone running linux can figure out how to run a bash script, and windows users have a bat file after installing 209387249087 drivers... but they still figure it out ;P)

HKC p771a 7 inch Tablet Root

I have used many different methods to root phones even a few tablets for friends. But I have bought a HKC 7 inch tab from walmart. Great starter tablet by the way. I have found no information what so ever on any forum about this model. It has decent processor power and runs rather smooth. Alas there is no way to root this thing to reach its full potential. I checked around on the net and found nothing, none of the one click apps work on this model. Adb does not recognize the tablet either. I've put in the tablet ID into the adb_usb.ini still no device found. I'm not looking for anyone to just hand me the root process on a silver plater, though that would be nice, but any help moving me in the right direction would be appreciated.
I rooted one of these for a friend at work,
sourceforge.net/projects/androidroot/ is the root that I got to work.
and I've attached the driver that the manufacturer provided me when I requested a driver for development purposes.View attachment Rockusb.rar
Here is how I got it rooted
1. Installed Java JDK and Android SDK.
2. downloaded and extracted Manufacturer driver from Rockusb.rar and right clicked on the .inf file and selected install.
3. Opened Android SDK manager, installed Android SDK for version of tablet, and SDK tools, and Google usb driver from extras.
4. Enabled usb debugging mode on the tablet, and enabled unsigned apps to be installed.
5. Connected the tablet via USB
6. when the tablet shows up in the device manager as P771A I selected to update the driver manually, and selected the google USB driver from the android SDK.
7. Downloaded and extracted the android root I listed above.
8. Run android root and when it says "press any key to continue" it is waiting until the device connects to the computer again, as it could be rebooting, and one time when the tablet reboots, there is no text, just a black screen, but it does eventually connect and you can continue.
Also. I extracted the root to my desktop. when I ran as admin, it did not work, because the files were not on the administrators desktop, only mine, so it might be a good idea to extract the root to C:\ drive, so if you need to use admin, it won't fail
hope this helps

6. when the tablet shows up in the device manager as P771A I selected to update the driver manually, and selected the google USB driver from the android SDK.
7. Downloaded and extracted the android root I listed above.
8. Run android root and when it says "press any key to continue" it is waiting until the device connects to the computer again, as it could be rebooting, and one time when the tablet reboots, there is no text, just a black screen, but it does eventually connect and you can continue.
Also. I extracted the root to my desktop. when I ran as admin, it did not work, because the files were not on the administrators desktop, only mine, so it might be a good idea to extract the root to C:\ drive, so if you need to use admin, it won't fail
hope this helps

when in doubt go back to the forums. I can not get the inf in the rockusb to install. "Installation for this file type not permited" . So I'm stuck, the program will not complete. I'm on windows 7 so maybe the driver is for another system. If you can provide futher help, Thanks in advance.
New approach
Ok I cannot get the drivers to install on my computer. Window 7 seems to default to its own driver and will not let me install the rockusb drivers.
With that said, I have the system Update.img and was wandering if the img itself can be rooted and then updated to the tablet. If this is possible and anyone with the knowledge is willing I will upload it. Or if someone is really patient and would like to walk me through the process and I will attempt to do this myself
No Help
So with no help I assume this is dead. I have a usb driver package with an .inf file a .sys file and a .cat file but this will not install on my computer thus leaving without a clue and no help. Have seached for a way to force install this driver command line install right click and install the inf. Nothing works so if someone wants to throw me a bone, thanks, if not I guess this thread is dead.

Can't tell your level of PC knowledge so if you already know this don't get offended. The .inf is editable and there are areas in there that allow manufacturers to prevent installation on some OS's to prevent conflicts. Make a system restore point or better yet a backup and then post the contents of the INF somewhere and point the folks here to it and they may be able to help you edit it to install. Regardless, you'll have to use the "have disk" option instead of letting windows search for a driver even if you get the edits right. And the usual disclaimers about me not being responsible for any issues with your equipment as a result of this are in effect.

I was able to root using the instructions above although i don't think you need the rockusb drivers. You just need the usb drivers that come with the android sdk. I am on Win 7. Thanks for the above info for rooting.
I was able to install ROM manager and now proceeding to backup ROM and upgrade using this guide: cant post link as forum is preventing, but search for rom flash guide on androidpolice com.
Hope this helps.
Big thanks to this thread to get me going...!!!
?
could someone please, Barney style, Explain how I am supposed to select the android_winusb.inf because my steps are as follows. Right click on device p771a in device manager, browse my computer, let me pick from a list of device drivers, have disk, point to the google usb driver (C:/Android/android-sdk/extras/google/usb_driver) select the android_winusb.inf open. Hit ok, (The folder you specified doesn't contain a compatible software driver for you device. If the folder contains a driver, make sure it is designed to work with windows for x64-based systems). Hope this helps explain my troubles. Glad that my thread is helping others to root this device but it does not work for me.
Could it really be that simple?
Found in another forum about the nexus 7 when connected to the pc there is a presistent notification that allows you to change the connection type from mpt to camera which will give you adb access and the tool from this thread works great. Thanks for the help guys, got my root on

Glad you could figure it out...
I was not able to use the ROM Manager to backup the ROM since the device is not supported on this tool, but see below for how you can obtain the stock image.
I've tried to flash multiple different ROMs using RKAndroid to the tablet, spending days on this, with no success. The tool itself works great and I am able to flash the ROMs since it supports the RK29 chipset which I believe this tablet has. The stock ROM for this device is available from the manufacturers web site (the link is available when you go to Settings => About Device => System Update, hkcdigital dot com slash update slash update.img), if anyone would like to take the stock rom and upgrade it to Android 4.2/JB.
I was able to unpack/repack the stock image using the wendal image tools and modify / cook the ROM using Android kitchen method described elsewhere in this forum. Rockchip Batch Tool is another great utility to flash custom ROMs to this device. Also, If you put the ROM as update.zip or update.img file on the microSD card, the tablet will take it and flash the image as long as it is in the right format. Ofcourse you can put the tablet into recovery and restore from there as well. I've found that the stock image (update.img) has the following file/folder format when unpacked: /RK29xxLoader(L)_V2.27.bin, /package-file, /parameter, /recover-script, /update-script, /Image/boot.img, /Image/system.img, /Image/recovery.img and /Image/misc.img.
Is it possible to upgrade this tablet to Android 4.2 or atleast Jelly Bean? Would be very helpful if someone is able to do this. The most success I've had so far is with the custom ROM Oma_Odys_Loox_JB_4.1.1_v1.2.2a flashed using RKAndroid. It flashed the tablet fine, updated the boot etc. On tablet boot I am able to see the new logo, but then the it doesn't go anywhere from there. I think customizing this ROM or the stock ROM we should be able to get the new OS on to the HKC tablet. I've given up for now since I don't have the time to spend on this anymore. If someone is able to do this, please post the instructions or upload the custom ROM, as I am sure it will benefit a lot of people and will be much appreciated. Happy cooking!
Thanks!
jawadshaik- rom manager
If you have successfully flashed rom manager on this device could you post the steps you took to do so. What version? Manual flash? The program itself says there is no recovery for this device.
Sorry jumped the gun on that last post. Thanks for the info
What's the secret to keeping the battery from draining so quickly while it's idle? I just got this and see it drained about 40% in about 2 hours I think and I wasn't using it.
tannerjames said:
I have used many different methods to root phones even a few tablets for friends. But I have bought a HKC 7 inch tab from walmart. Great starter tablet by the way. I have found no information what so ever on any forum about this model. It has decent processor power and runs rather smooth. Alas there is no way to root this thing to reach its full potential. I checked around on the net and found nothing, none of the one click apps work on this model. Adb does not recognize the tablet either. I've put in the tablet ID into the adb_usb.ini still no device found. I'm not looking for anyone to just hand me the root process on a silver plater, though that would be nice, but any help moving me in the right direction would be appreciated.

@jawadshaik
Just out of curiosity, when you were flashing that Rom that brought up the boot screen, did you do a wipe/factory reset from recovery mode before flashing? I have no idea if that would help or not, but most if not all roms require a data wipe before flashing... Just curious if you had tried this as I have heard of this happening on other devices because a data wipe wasn't done first. Might be worth a shot if you haven't tried it already, just a thought

So after doing working on this a while, I've finally figured it out. Here are some caveats:
1. You can't do this on a Mac or Linux box. Don't ask me why, you just cant.
2. You have to turn on USB debugging, change the Security to allow Unknown sources and MOST IMPORTANT: when you plug it in, you have to change it to "Connected as a Camera". Putting it in storage mode doesn't work!
HOW TO INSTALL THE PROPER DRIVER & ROOT THE DEVICE:
1. Follow the steps quoted above and download the Google Android SDK, and the Java JDK (from oracle.com/java).
2. When you first plug it in (use the USB plug labeled USB not the HOST one), it complains and will discover a P771A device. When it does, right click on your computer, choose Manage my computer, go to the device manager and then right click on the P771A device. Click "Update Device Driver". Choose "Browse my computer for Driver software". Then choose, "Let me pick from a list of drivers on my computer". Browse to the \adt-bundle-windows-x86_64\sdk\extras\google\usb_driver folder which you would have if you had downloaded and installed the Google Android SDK. A list of 3 drivers will appear when you click OK. CHOOSE THE "ANDROID BOOTLOADER INTERFACE" as the driver. None of the others work.
3. Run the root script batch file mentioned above which can be found here at: sourceforge.net/projects/androidroot
4. The root script isn't really great at explaining so I'll try. When you first run it, make sure your device is unlocked and on the home screen.
5. The first thing it will do is reboot your machine. Don't press enter until your machine comes back up.
6. After your machine boots unlock it and then press Enter again. Your machine will reboot. This time it won't seem to come up but the backlight will remain on.
7. Wait about 30-45 seconds then press enter again. You should get: uid=0(root) gid=0(root) in the command prompt window.
8. Press Enter. You should get:
remount succeeded
727 KB/s (22364 bytes in 0.030s)
Removing changes except ROOT...
Installing superuser...
2288 KB/s (843503 bytes in 0.360s)
9. After about 30-60 seconds, your device should reboot. You'll see a box briefly saying "Android is Upgrading" and you'll arrive at the lock screen. Press Enter to exit the command prompt.
Your device is now rooted and you should see "SuperUser" installed. I promptly installed "root uninstaller" to get rid of Facebook, Skype, and Youtube which my little kids don't need access to. This device doesn't have a bootloader or recovery mode so rooting it doesn't get you much besides the ability to uninstall the system software. Have fun.
This may help someone but on step 2 of the guide on the second page, after you right click your device and go to "Let me pick from a list of drivers on my computer". You then click "Show All Devices" then "Have Disk..." Direct it to the root of the adt-bundle folder you downloaded then you can select from the three drivers. I'm on windows 7 32bit and the drivers didn't show up for me like how it was suppose to..
I also could NOT get any of the drivers in the "manufacturer USB" packet to install... I WAS able to install the google drivers, but that also would not allow ADB to see the device... So still stuck with everyone else...
P771A possible problem
I'm having a similar problem where the USB driver downloaded through Android SDK's -> Extras -> Google USB Driver, tells me that the file contains no information about my device. I noticed in the Sources of SDK, there wasn't an API for 4.0.4, only 4.0.3 then 4.1, so i downloaded 4.0.3 repo.
============================================
my devices is on 4.0.4, and my Kernal is as follows:
3.0.8+
[email protected] #8
Wed Aug 29 09:59:19 PDT 2012
Build Number:
P771A-user 4.0.4 IMM76D user.v402.007 release-keys
============================================
I've also made sure weather Unknown Sources is on, as well as USB debugging.
Might the Kernal be the problem? Also, does it matter weather its MTP or CTP?
Now HKC is telling me that they don't support the ability to jail break their devices

Do this root apply to the s8-50F ?
EDIT: This method indeed does work on the S8-50F variant. Was having problems with device staying in adb while running program, but a reboot of pc fixed that and gained root effortlessly. THanks!
Glad It Helped !!!

The download isn't working for me. It's not downloading as a zip? Any suggestions?
If youre using windows, download a program called 7-zip and downoad the file. right click the root software and click extract here. or open with 7-zip. You could also use winrar. The format of the file is in .7z right ? that means search up http://www.7-zip.org/
Any idea how to unroot?

Thanks both of you. I ended up returning it, root and all, but I'm sure your suggestion would have worked.
After rooting, has there been anything anybody's been able to do about battery life? I don't imagine there's been any Roms built for this device yet, but didn't know if maybe someone's figured out something that's helped extend their battery life, because when playing certain games like clash of clans for instance, I'm lucky to get an hour and a half of game play, and that's with my brightness turned all the way down. Any suggestions would be greatly appreciated. Thanks

This root guide works on s8-50f! thanks Xakep
This is a very easy and usefull root instruction, i rooted my tab s8-50f with no problems.
I followed the steps described and got instant root without any issues.
My machin is windows pc with windows 8.1 pro 32bit. Plug your tab and windows recognized the drivers just make sure your device mngr shows lenovo s850 and you are all set. Then just run the flash tool and it will run in less than a minute your tablet will reboot and your tab will be rooted.
Yes this is probably the easiest I've ever rooted any device in the past. If at first it doesn't take, don't worry it will. Just repeat the process till it does. Thanks Hash.h for putting up this thread and passing along the info

Where can I download the ADB drivers for S8-50 from?
I think drivers come with tablet. Try to connect the tablet and it will show CD drive on which is the driver.
error: device offline?
I followed this with no luck. I have adb installed and running "adb devices" shows the tab connected, but when I run the tool "error: device offline" scrolls repeatedly and no root.
Any suggestions?

Worked great. Thank you.

Tried on another computer and succeeded.
This worked brilliantly...
but then I upgraded my firmware using the in-built system and it de-rooted. Now the exe no longer works.
New firmware is S8-50F_S000200_150121_ROW
Exe -appears- to run well, but appears to fail on the last command. Unfortunately it disappears off the screen before I can check the exact nature of the error. It appears to go fine until the final attempt to copy the SU binary into place fails with a 'File not found' error.
I've also tried the other method here:
http://forum.xda-developers.com/general/rooting-roms/guide-lenovo-s850-row-t2927400
The flashtool fails to find the device (I know the drivers are installed), so I'm unable to install the new boot image.
ADB shell fails
mount -o remount,rw /system
with the response
mount: Operation not permitted
so none of the 'push' operations will complete as the /system folder is read-only.
Any suggestions?
