Hello,
Been trying to get droid explorer and adb to reconize my tilt2. Here is run down of what i have done.
on an up to date windows xp box
installed latest pdanet for android
installed latest droid explorer
connected my tilt2, it installed the adb driver but wont install the 2 cdc asm drivers
run droid explorer and it doesn't reconize the phone. i have the phone in debug mode and notification does come up.
on the android side i am running
frx 5
wistilt2 test kernel
highlandsun ril driver
btw, tried to run the busybox installer and it says it cant gain root access.. i thought all these builds have it by default or am i missing a step or two. I have superuser installed.

All you need is the XDA device to install. The other two, CDC etc are not needed.
Is the adb service running? See if adb.exe is in task manager. You only need pda.net for the drivers, the software will mess with adb itself. So make sure their software is not running.
What do you mean busybox installer? For Titanium Backup or...?
You don't need SuperUser, that is an app that is more for security - if something asks for SU, it'll let you allow it thru the app. Yes, all our HaRET builds are rooted.

I didn't have a problem, My drivers installed automatically for me, but I'm using Win7.
You don't have to have pdanet or superuser for DroidExplorer to work.
Goto your device manager and see what device is listed under ADB interface. My Rhod300 shows up as a HTC DREAM.

Did you try mine? Remove pda.net, once you have the drivers no software is required from them.
Plus, you might also try the good ole reboot, and ensure that adb.exe is running in the task list.
All things I suggested previously...
yes, i've done the suggestion. It shows its connected. Under device manager there is an android phone, under that there is android adb interface but nothing under that. I don't know what else to do. Is there something i am missing on the android side?
and adb is running in taskmanager.

and you've rebooted?
I'm out of ideas, I've installed adb on tons of computers, win7 xp etc and all work flawlessly. It is a pretty advanced debugging tool, it's not very easy to install or use...
yes and i have rebooted twice now. still the same thing.
Boot android on phone.
Plug phone in.
Run Windows update.
Check device manager to make sure everything has drivers installed.
Run DroidExplorer
phone will show up as 00000000 in DroidExplorer
Reinstall DroidExplorer if problem persists.
Oh and there should be a device or driver in device manager called XDA, if memory serves me correctly.
Had the same problem about a month ago... downloaded PdaNet from the Marketplace here and it established the connection so I could use the USB to my phone. I didn't have to run it or buy it though .. just install it.
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.

Moved To Q&A
downloaded all the stuff from the thread. everything went smoothly. i watched the video step by step. after uploading the usbdrivers to my NT it said
"Android ADB interface" instead of "android composite ADB interface"
it shows up in my device manager as a nook tablet still.
i derped. so i thought it would be ok anyways and then tried to zerg rush the baster-ahem NT only to see that the Zerg didn't even find my device.
i promptly decided to just wipe everything from my nook and start fresh but also every single thing i tried has failed to get rid of that blasted "android ADB device" from the one click unroot thing to doing a 8 step reset thingy and just plainly reset and wipe data from the stock settings, and now many hours later i have had enough and decided to swallow my pride and flaunt the noob card. i need help. i must find a way to wipe everything or maybe i can take a step from here. i dunno. derpy derp.

hm... well not sure if this is hidden anywhere in your description but did you try reinstalling the nook tablet drivers? since you have android adb device right now, uninstall that and if windows prompts you to restart you should do that. When you uninstall the adb drivers if there is a checkbox saying delete driver software for this device make sure to check that as well. basically what i am trying to say is you want to start fresh as in there should not be any reference to android or nook on your windows pc
another program that may be helpful is using usbdreview which is a program that monitors all devices with usb drivers. this may help is attempting to delete any reference to android and nook on your windows pc. hope this helps!
EDIT: just to add this tidbit in, if your having troubles with ADB, chances are it has nothing to do with your NT but rather with the drivers that Windows has installed already. There's a guide to installing ADB correctly, here's a link:

hm.. well if it keeps on auto installing generic drivers you will need to disable auto installation of drivers by windows. try looking through each of these links and see if it solves your problem. fyi you should uninstall all drivers relating to android and nook before proceeding

well this is weird one atleast for me. i had all those settings on at the very start of the rooting process. and in the end i need to enable in the system config the USER to override the automatic driver install policy. so my anti install was thwarting me this entire time!!! ugh!!! total noob but we all gotta start somewhere. thanks to everyone for helping me out!
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.

@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:

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+

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

Its finally here guys, the moment you've been waiting for, ROOT for the Lenovo Tab S8-50. To Root Your Device, All you have to do is enable developer options/mode by tapping on your build number multiple times. Then navigate to Developer Options and make sure you enable USB Debugging or else your PC wont recognize the tablet.

Requirements and conditions:
1-Make sure that your computer is not connected to other Android devices
2-Make sure that you have installed the ADB drivers for S8-50 tablet
3-Make sure that the machine is turned on USB debugging
4-Connect the device to your computer via USB

If you get an error during the rooting process that said "adb server is out of date killing adb server didn't ack" or something like that, there is a way to fix it. Open Task Manager on your PC and try closing adb.exe and restarting it, or just Google the error and you will most likely find a way.

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.
