Help Kindle Fire HDX 7 - Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot

I have a rooted kindle and the past few days my Wi-Fi isn't working right. Some days it will switch right on and connect other says you switch it on and it does nothing and acts as if the wifi is still turned off. Please help. I did factory reset and it didn't help. I can post a video to YouTube to show you if you need.

- known side effect of KingRoot
- toggling Airplane/Flight mode should work; give it a few seconds to connect
- consider a custom ROM if further relief is needed; Fire Nexus (KitKat based) works best if WiFi reliability/stability is a priority

worse issues lol
I tried that and now I have royally screwed it up lol. I was in the recovery menu which is team win recovery project v2.8.6.0 and I think it was the advanced wipe which I was thinking was basically a factory reset and it deleted the OS. I tried connecting it to my laptop and have been at it for over an hour and can't get it to connect to my windows 10 laptop. I installed the drivers from amazon. In device manager it shows as Android Phone > Google Nexus ADB Interface but I can't actually see it in my file manager area to try and put the stock kindle back on it. At my witts end and my daughter is so mad she cant use her tablet (she is 3 lol) any help is greatly appreciated.

Obviously the first step is to gain access to the device so files can transfered to it. Unfortunately, TWRP 2.8.6.0 has a mixed record when it comes to exposing the device to Windows. There are alternatives but it gets ugly fast unless you are comfortable messing with adb/fastboot commands.
Suggested path:
- on Windows 10 install this package to obtain drivers that are know to work with 3rd gen HDX devices
- untether device
- open Windows device manager
- boot HDX into recovery (TWRP)
- tether device; take note of what entry(s) appear in device manager
- right click those entries and click 'uninstall'
- untether HDX, wait a few seconds then retether
- when Windows prompts for new drivers manually navigate to "Mot Composite ADB Interface"
- open File Explorer in Windows ... does device now appear?
There a lot of assumptions built-in to those skeletal instructions starting with familiarity with dealing with Windows devices and drivers (ugh!). Give it a whirl; post back with questions.

LINK?
When I click the link to download package it shows up to a thread to download motorola package? Should I be downloading that? Thanks.

Yes - Motorola drivers have proven to be highly compatible with HDX devices. The link will install some other stuff that is not needed but is otherwise benign (does not run in background, etc).

My other Kindle Tethers fine
I am not sure if this makes any difference but my other Kindle which is exactly the same except unrooted tethers just fine to my laptop. It immediately shows up in file manager as Fire when I plug in the cord.

I am installing that motorola driver now. Seems it may take quite a while to install.

It didn't change anything. It still shows in device manager as Andriod Phone > Google Nexus ABD Interface and the only thing it does when I right click is open properties and in properties it has General, Drivers, Details, Events and under drivers my only option is Driver details and it also says Driver Provider: Clockwork Mod.

Drag and drop is the way to go. In Windows File Explorer you should see an entry titled "Kindle Fire HDX" (or something similar). Drilling down the next layer should say "Internal Storage". Going further should yield a handful of folders, one of which should be labeled "Download". Put the ROM zip there.
On the HDX boot into TWRP, whap the "Install" button and navigate to "/sdcard/download".
Note you can NOT reinstall stock FireOS using this method. Unfortunately, the HDX has no native method for recovering from an OS wipe. There are ways to get FireOS reinstalled but there are several caveats.
If uncertain which ROM to flash I suggest starting with this one. While relatively old it goes in easy, works with older TWRP builds and is feature complete. Can always upgrade later. Post back with any questions.

When opening the kindle with file explorer I see internal devices then twrp and in that folder is a single file called twrp. I

I am going to try just dropping it in the twrp folder since that is the only folder I have and if that does not work I am not sure what to do. Could I possible create the Download folder within the internal storage folder?

Glad you got it sorted. FWIW:
- Thor = 7" 3rd gen HDX (your device)
- Apollo = 8.9” 3rd gen HDX

Thanks for the help everyone. My problem is solved.

my lappie which is a
Windows Vista 32 bit
it is not detecting the APX mentioned in the thread
http://forum.xda-developers.com/showthread.php?t=861950
Now I am fixed in a reboot loop and I have tried everything suggested in this thread
OK I know I had no business doing this because I dont know the D of developing....
but the TNT Lite worked so well and was so easy to install I got carried away by it and tried to install the amd to let my computer detect the gtab. this is where I got stuck!!
to start from the beginning
I installed TNT lite on my GTab and it worked really well, I could see Youtube videos and access the Android market
Then I thought I should maybe transfer a few files to the Gtab so I could view them, but when I tried to do that I found out it was another long process, Normally being a non developer I would have probably just tried to find out a non hacking method to do this like download it from gmail or something. Or just use an SD card
But it had been so easy to install the alternate ROM from instructions in this forum I thought maybe it wouldnt be a big issue..sad!!
It was!
Now my one day old GTab wont start up and if it does it just keeps displaying a weird kind of screen with squares on it which I am assuming is the reboot screen
And so I tried to use Nvflash to restore it like mentioned in the thread above but my lappie wont detect it at all..
So now I really need help before I attempt anything else on my own
I dont want to send my Tablet back and would appreciate any help from experienced developers like you guys...!
Please do help me and I promise never to attempt something like this again..!!
Thanks
please !!!! anyone!!!!!
First, I think you need to breathe. Patience is a virtue. *NOTHING* about being excited will help. So calm down first, then go.
Did you install the drivers listed on that page?
Here's a direct link:
http://www.myadventvega.co.uk/SystemUSB.zip
Getting them to install can be a bit tricky, though, since it's not an executable. Download it, unzip it, go into the Flash USB folder, go into the USB folder, right click on the nvidiausb.inf file, and select install. That *should* install the driver. However, it might not. If it doesn't, post back and say what happened.
And as far as transferring files - there's no need to hack to do that. Just connect via USB, pull down the USB attachment notification on your tablet, and say connect. Then drag and drop on the computer. Done.

Thanks, I think I did forget to breathe..
It says " the inf file you selected does not support this method of install"
Alright. Crap. I forgot that happened to me too when I had to do it.
I think I had to install it via using Device Manager. Here's how you can get to it in Vista (I'm about to sleep, so I'm saving typing time):
http://windows.microsoft.com/en-US/windows-vista/Open-Device-Manager
Once you've got that open, go ahead and boot the tablet into APX mode, meaning that from a powered-off state, you'll hold down the power and volume - buttons simultaneously until your G-Tab comes up and the goes back to a black screen (words stolen from the original NVflash post).
Connect it to your computer (while Device Manager is opened). When you connect it, you should see a new device appear that is labeled Unknown Device. Right click on it, and select Properties. Click the Driver tab (may be different - I'm on 7, but I think it's the same). Click the Update Driver button. Choose the "browse my computer for driver software." Using the browse function, point it to the folder with the inf in it (%wherever_you_extracted_it%\System USB\Flash USB\USB). Click Next.
I think that's what I had to do on mine when I borked my tablet with an experimental build of Vegan Ginger. If the driver installs, that should allow you to then go on with the rest of the directions. If it doesn't, post more information. I can't promise I'll be on any time soon, but maybe someone else can help out if they're up.
ok it says at the end when I have pointed it at the driver file (NVidiaUsb.inf)
"The folder you specified doesnt contain a compatible software driver for your device. If the folder contains a driver make sure that it is designed to work with windows for 32 bit systems."
This is what happened last time also, and then the system says that I already have the most compatible driver for the system and puts me on "Microsoft WPD filesystem volume driver"
EDIT: I should mention that I also had a tough time deleting my NVidia driver, but as soon as it was deleted, it was automatically replaced by the "Microsoft WPD filesystem volume driver"
Not sure what to tell you. The INF clearly points to the x86 version, so it should install. Is there more than one unknown device in your device manager? If so, you might somehow have the wrong one, though the approach earlier should have made it easier to track the new one.
Sorry. You might want to try getting on IRC to see if other people have some bright ideas. An NVFlash does seem like what you need to do, though.
EDIT: I did some digging into the forums (you should probably continue that). Here's a thread all about these drivers.
http://forum.xda-developers.com/showthread.php?t=1012009&highlight=NVFlash+USB+Driver+Solution
If those fail, there's another method that involves installing the entire SDK, which is linked on this thread (the second post about the MSI):
http://forum.xda-developers.com/showthread.php?t=882814
However, my impression is that that option might create more complexity than it's worth.
I haven't done anything but what I explained earlier (if I remember right - it's been a while), so I can't talk about any other approach. However, these will at least maybe make my failure into less of a dead end.
I ran into the exact same problem a few weeks ago after installing CM7...
http://forum.xda-developers.com/showthread.php?t=902860&highlight=usbdeview
I used a program called USBDEVIEW and just obliterated all the usb drivers (I guess the safe way is to remove any mention of Nvidia usb devices) and rebooted the computer. Let the system reinstall all the USB devices. Restarted the computer again. AND ONLY THEN did I plug in the gTablet. Once plugged in, the system automatically installed drivers and recognized the tablet, you may have to point to the inf file if it fails to install automatically.

Good luck!
Don't let this setback keep you from using great ROMS like VEGAn Tab Gingerbread RC1... once you've mastered the NVFlash process and CWM recovery install (I prefer the external CWM install) you are all set for other mishaps.

I tried to uninstall the nvidia drivers using USB deview, it asked me if I wanted to uninstall drivers I said yes but I can still see the drivers in the USB list
Is that ok?
You need to run USBDeview as an administrator. Right click on "USBDeview.exe" select "run as administrator" and then when you are asked to confirm, click "yes"
Only then when you "uninstall selected device" the device will disappear. Otherwise you are only in view mode.

OK I just figured that out and was coming to post that. Thanks for realising that is what I was doing..
I conneccted the tablet to my PC.but it still does not detect it
The only time my PC detected it was the first time when I pointed it to the nvflash folder. After that it has never detected it and I havent seen the yellow ! icon.
what am I doing wrong?
Firstly, powerdown the gTab.
Turn on power while holding "vol -" to enter into APX mode (you'll see the viewsonic birds then the screen will go blank)
On the bottom right corner of the Vista screen, click on the USB icon that says "safely remove hardware and eject media"
Look at the list the pops up, does one of the devices say APX?
no It only says safely remove mass storage device
oh wait
my tablet switched on to the reboot screen and didnt stay black
trying it again
it installed "NVIDIA boot recovery driver for mobile devices", is that correct?
This is where I get stuck, my device manager doesnt show the apx at all whatever I do, what am I doing wrong?
I think there was a way to overlook safety signatures somewhere but I couldnt get to do it,
Is there some way I can ask my computer to overlook the safety signatures?
EXCELLENT!!! Now you are ready for NVFlash instructions:
http://forum.xda-developers.com/showthread.php?t=861950
BTW, you will not be able to see the device under windows explorer as in the normal way such as "D:" "E:" etc drive.
Once you get everything setup per the above instructions and run "nvflash_gtablet.bat" you will see the flashing process in the text box.
Just want to make sure...
Under Vista Device Manager
-- "universal serial bus controllers" you have "NVIDIA USB Boot-recovery driver for Mobile devices"

Yes I do, so I should start the process now?
THANKS a lot, will update you as it goes on.
Yes, follow Roebeet's instructions and you should be set. Also play it safe and keep your gTab plugged in unless you are sure of the amount of battery life left.

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.

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.

Thats the problem the prompt never comes up. Running Windows 7
Well I got the driver for adb to install but it still will not show up when I do adb devices

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

Step by Step guide to enabling ADB Connection on your stuborn Nook Tablet

(I cannot post links at this time, a quick Google Search or a look at the Topic titled "Full Root")
The goal of this guide:
I rooted my family members Nook last night but got hung up for a few hours trying to get the ADB Drivers enabled. This is how I made it work. This guide will be expanded and improved once I have my own Nook Tablet (Jan 12th).
Things you need:
• Nook Tablet (Duh)
• USB cord to go between NT and Windows PC
• PC with Windows installed (Tested on XP and x64 Windows 7)
• TGPS_Launcher.apk Installed to your Nook
• ADB USB Drivers for Nook Tablet Extracted to C:\Ntroot on your PC
• USBDeView open on the Windows PC
Step 1:
Ensure that your Nook is version 1.4.0 and not 1.4.1. (I will expand this step later when I have a nook in my hand, I suggest a Google search if you do not know how to do this)
Step 2:
Find this thread on your Nook and download the TGPS_Launcher.apk to your device, then install it. This is well covered in many other threads. (Will expand this step when I have a nook in my hand)
You should now be able to allow USB Debugging, and disable Auto Mount. These settings can sometimes change without your permission, so always uncheck and recheck them to ensure they are properly set.
Step 3:
Plug in your Nook to your PC. Your nook should still respond to your commands, if it tell you in USB Mass Storage mode, then retry Step 2.
Go into your Device Manager. If your Nook shows up with a yellow explanation mark indicating an Error, then you’re in business and really don’t need this guide. All you need to do is update drivers from the file C:\Ntroot. However, assuming that your Nook shows up under Disk Drives and USB Mass storage, then ADB wont be able to see your Nook, please keep reading.
Step 4:
Time to start the USBDeview utility. This utility will open to a list of almost all the drivers your computer has for USB Devices. We are going to uninstall a few of them, namely anything that says “Android” “Nook” or in my case, “Motorola”. You do not need to remove any that specify ADB.
Near the top right hand side, you can sort drivers by when the device was last connected. Do this, then remove any utilities used when you plugged your nook in. Done? Ok, time to see if your work was for nothing.
Step 5:
Make sure once again that USB Debugging is turned on for your Nook. Unplug the Nook, then Unchecked USB Debugging and Check it again. Now plug your device back in and check in Device Manager. You will hopefully see one of two things:
A: You will see your nook with a yellow error icon next to it, which means you just need tell it to update from C:\Ntroot.
B: At the top of the device manager you will see Android Devices, and your nook will show up as Android Composite ADB Interface
If your Nook is still showing under disk drives and mass storage, then try steps 3 and 4 again. Still having trouble? Do a factory reset and try again from step 1.
You should now be able to run your rooting program!
(I feel this should be in the Dev forum, but this is my first post and I was not allowed. Perhaps a mod would like to move this topic?)
I plan on purchasing my own Nook on the 12th on Jan, at which point I will add pictures and expand on my guide. This guide is written from memory and will be edited and improved.
Please consider this guide an Alpha Version
Good write up!
The procedure worked fine on my laptop. When I did it on on my home PC I forgot to disable auto-mount and the Nook installed itself as mass storage. I was able to right click -> un-install all the USB Mass Storage entries (with the Nook unplugged), disable auto-mount, plug the Nook back in, and have it show up correctly.
In short, I did not need to use "USBDeView" as I was able to remove the diveres manually. I suppose if you have more than a handful for USB devices (I just have a Mouse, Keyboard, and printer) "USBDeView" might be helpful to determine which drivers to un-install...
The device manager is enough for most people, but there is a somewhat large number of us that are having trouble still. Possibly because of other devices we have installed before. (I dont understand how all the drivers work and I wont pretend to)
Some people have go so far as putting a fresh install on Windows on a partition of a PC.
I had this problem with both my laptop and my desktop, which surprised me. This worked on both the laptop and PC, so hopefully it can help other people.
I cant wait to get my own tablet on the 12, I will take lot of pictures and make this process more user friendly.
I did all of the steps several times and I still get WPD Driver for the portable device and mass storage for my Nook Tablet. I am guessing I am up a river without a paddle right now.
I will try it in Linux and/or try it on someone's Windows machine.
I am trying to install the drivers from Google's SDK package. So I browse to the correct folder, but device manager says "windows could not find driver software for your device".
Any suggestions? Is there any other set of drivers specifically for NT?

Did you sort by last time plugged in and delete all of those too? Have you re-checked and then re-un-checked automount/usb debugging and such?
This is interesting, you'll have to come back and let me know if you ever get it working on your PC. Maybe its a good excuse for a nice healthy re-format and reinstall of windows?

I don't know if they are different, but I used the drivers specificly from the thread about rooting the NT. [I would post a link, but I'm typing from my phone]
You have the yellow error mark next to your device? If so you've almost got it!

Yeap, that did the trick, thanks. Drives installed successfully this time, but adb devices still returns nothing.
Thats very odd. It shows up in device manager as an ADB device?
If so, please try the NookandZergy file, then copy the results so we can try to farther assist
What devices have you rooted before?
I cannot help but feel I will be 100x more useful in a week when I have my device in hand...
adb error: device offline
This drove me nuts for at least a day. Turns out it is what happens when you are plugged into a USB 3.0 port on your PC side. Find out which USB is 2.0 (Front Panel for ZT Systems), use it and life suddenly gets really good.

Well I have done everything and still get permission denials for copying and chmod on my Nook Tablet.
Took the Nook to work and tried it on a fresh machine. Everything went great. Drivers installed and everything ready for usb debug and non-automount and then I run into the same permission errors and being denied access to the folder for Zerk and no chmod.
Same issue no matter what machine. What is wrong with my tablet? I am re-rooting it from being automatically upgrade to 1.4.1. I get it to 1.4.0 with the SD card restore.

Did you find a solution? Thats a problem I sadly dont know how to help with. I would start with:
-Check USBDeview and delete anything android/Nook/usb related. Delete just about everything.
-Restart the device
-Uncheck and recheck the USB Debugging boxes
-Recheck and uncheck the auto-mount box
-Test
-Try a different USB Port
-Try another PC
Thanks but didn't work.
thanks, Joe. I did exactly as you mentioined below and had the Android/Nook appear at the top of the Devices listing. However, the adb command still can't find the device. Any suggestions?

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

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.

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.

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

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 1468367
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

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?
Not sure. Have you tried the full unroot method in the su app?

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?
Thanks
Worked great. Thank you.
Awesome little tablet.

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?

Same problem here. Lost root after the last update and now I can't get either root method to work.
