Problem with step2.cmd

I've finally getting around to rooting my x10a, but I'm having a problem with step2.cmd. It echos it's schpeel that select option 6 or whatever, without any error (except for the normal "device not found"). I know that it's supposed to come up with a screen that you should select the 6th option on, but it's not showing up!
If anyone is wondering I do have USB debugging on and I have installed all the drivers.
EDIT: I did include the deviceid txt files inside both of the folders.

Actually, "device not found" is NOT normal. It shouldn't say that if it's working properly.
Steps 2 and 3 (and 5 for X10a) use ADB. There are a few things to check (I'll list everything I can think of, including ones you may have already done):
1. ADB doesn't require DeviceID.txt (it's for X10Flash), so it's not that.
2. Make sure USB Debugging is enabled on the phone (under Settings > Applications > Development).
3. Unplug the USB cable and plug it back in. On the phone, the notification bar should show "USB debugging enabled".
4. Make sure that the SD card is NOT mounted to your PC. The notification should show "USB connected", NOT "Turn off USB". If it does say "Turn off USB", then click it to turn it off.
5. In Windows, double-click on the Safely Remove Hardware icon in the system tray. There should be a device called "adb01 ADB Interface Driver". Don't remove it, just make sure it's there. Hit Cancel/Close.
6. Open Task Manager (Ctrl-Alt-Del) and look for a process called "adb.exe". Click it and hit "End Process". Next time you start adb, it should load up the daemon again.
7. Have you tried rebooting your PC? How about your phone?
8. ADB connects using TCP. If you have a software firewall (e.g. ZoneAlarm, Eset Smart Security, etc.), it may be blocking access. Either make an exception, or just disable the firewall for now (don't forget to turn it back on later). No, a router doesn't count (the phone is connected through USB, not your network).
9. There may be a problem with your Sony USB drivers. Uninstall Update Service and PC Companion (if you have them), reinstall them, and then plug in your phone again so that the drivers are reinstalled. I had to do this to fix a different problem (that second USB Mass Storage device kept connecting and disconnecting).

Did you allow unknown sources?

I've done everything but that, which is not there, what should I do about that?

You know what, the laptop I'm using right now really sucks in the spec department, so it might just be that. Is there anyway to reflash it to rogers x10a?

is your laptop using vista 64? If it is follow this post to fix it. http://forum.xda-developers.com/showthread.php?t=713457

device not showing up in debug monitor

I have my sg4 plugged into my laptop, but it is not showing up in the android debug monitor. I ran it as administrator, and the device does show up in my computer.

Do you have debugging enabled in Developer options? Make sure you have the right drivers installed otherwise you may need a reboot on both devices

I have the Nexus 7 drivers installed, and the adb interface.
and I do have debugging enabled.

I think that you need the Samsung drivers. The Nexus 7 drivers are different ones. So download them here: http://www.samsung.com/us/support/downloads
They should also be installed if you install Kies.

There is a well-hidden menu that you may need to access.
Assuming you have developer mode enabled...
- Go to Settings, then Storage
- Click on the menu (top right)
- Select USB computer connection
You'll see 2 boxes:
- Tick 'media device'
I found that if neither box was ticked, I couldn't see my device...

Maybe the first time the dialog says "Allow this computer debugging" appears, you clicked NO.
Try go to Developer options and click "Revoke USB debugging authorizations", and reconnect the device.

Kogan Agora HDMI Smart TV Quad Core - Root Access

Hi,
So I have had a good experience with the Kogan Agora 7" a couple of years ago. I flashed a new ROM and my 6 year old still idolizes it. It's perfect for games and movies while traveling and cost bugger all.
I was considering getting my kids a console unit for games but came across the new Quad core HDMI Dongle. I though to myself there is the ticket, When traveling i could use it as a smart TV (plug and play is King) Or it may be possible to replace or augment my Media-portal HTPC system.
I bought one and on the face of it it appears to do all that I require from an Android device like web surfing, mail checking and video streaming fine, except when it came to installing the Playstation controller.
I needed Root access and it was a bit of a pain to get it done. BUT I found it!
I used RK3188_ROOT for CX-919 FW0715 MOD by Everal. found here.
1. Turn the device on
2. Make sure USB debugging is enabled
3. Connect the device to Win7
4. Start the file "TPSparkyRoot.bat" as admin
Enjoy.
So if anyone decides to purchase one of these to play with, you will be glad to know that it is a Rockchip RK188. Weather you think that hardware is good or not is irrelevant but it is useful to know as I tried many methods to gain root but once I had this bit of info it became easy.
Those infinity Pocket PC's may be the same although I can't be sure.
I managed to pair a sixaxis controller and am working on getting it running in a game. I will post if i have any more issues and or success.

Thanks for posting this info. However I'm not able to get this to work. My PC doesn't recognise the device when it's in "USB Debugging" mode. In the device manager it just appears in "Other Devices" as "KHSTVQCDONA". I've tried updating the software, selecting the "usb_drivers" folder containing drivers provided in the downloading Zip file, and also tried downloading the "Google USB Drivers" directly from Google, but Windows doesn't find the drivers for this device.
If I disable "USB Debugging" the device does connect successfully under "Portable Devices", but clearly that's not much use.
I can't seem to figure it out.
Below are the steps I took in trying to get it to work. I was going to write it as a guide for dummies, but I never got it working...
Download the software from the link above. On the "Share-Online" page click the small-ish button that says "continue for free", and not the bit "DOWNLOAD FILE (regular download)" button in the banner ad (that I feel very silly for clicking several times).
Once the file "RK3188_ROOT for CX-919 FW0715 MOD by Everal.zip" has finished downloading, extract it to a temp location on your PC.
Make sure the Micro-USB port of the device is connected to a power source (either your PC or the provided AC adapter). The port doesn't seem to transfer data.
On the Agora device, go to "Settings", open the "USB" menu, and enable "Connect to PC". Without this the device wasn't recognised by my PC at all.
In "Settings", click on the "Developer options" menu, and tick "USB debugging".
Connect the provided blue Male-Male USB cable to a full-sized USB port on the device, and to a USB port on your PC. At this stage the device connects but is not recognised.
Open the Windows "Device Manager".
In the "Device Manager", expand "Other Devices", then right-click on "KHSTVQCDONA" and click on "Update Driver Software".
Click "Browse my computer for driver software".
Navigate to the "usb_drivers" folder of the software you extracted earlier, select it, and click "OK".
Click "OK". THIS DIDN'T WORK, stating that "Windows was unable to install your KHSTVQCDONA" and "Windows could not find driver software for your device".
[*] Open "Command Prompt", by right-clicking on it and clicking "Run as Administrator".
[*]C:
[*]cd RK3188_ROOT
[*]TPSparkyRoot.bat
At this point I see the following:
*---* VonDroid.com N101 II Root Tool based on work by sunnydavid *---*
--- Plug in your device, make sure debugging is enabled in Developer Options
--- This script will now copy files over to your N101 II
error: device not found

--- Reboot 1/3 - Press Space Bar once the device has rebooted

--- Reboot 2/3 - Press Space Bar once the device has rebooted
Press any key to continue . . .
error: device not found
--- If the ID shows as 0/root then continue, otherwise CTRL+C to cancel and star
t over
Press any key to continue . . .
Click to expand...
Click to collapse
I terminate at this point
I've also done the following
Un-ticked "Verify apps over USB"
In "Security", ticked "Unkown sources", and un-ticked "Verify apps"
At this point I'm totally at a loss.
I had already started using the device initially, so I did a factory reset, but this hasn't helped at all.
Can you see anything I'm missing, or point me in the right direction?
Many thanks in advance! :good:

Ok So I know i messed around with many drivers installing and uninstalling before it worked. I Thought it was the last set that came with the Root method but I may be wrong.
Also I cant remember exactly now but I am pretty sure if you activate the connect to computer you bypass the ROM and connect to the SD card and the U SD. So that would not help when accessing the root files.
Try re-installing the drivers after connecting without the box checked in settings or try the ones from super oneclick 2.3.3 or even the pocket pC ones. you may also need to uninstall the device then reconnect to get a clean run at it. Windows likes hanging onto what it thinks is the best driver even when they don't work or are completely wrong.
Also I ran the batch file form within windows not in console, Just right clock to run as administrator.
I have just used it for a couple of weeks in Japan get let the Kids watch Aview (iView) and it worked a treat. Also the latest sixaxis updates made the controller even better than before. I can probably have a tool around with it later this week but I am busy before then so wont be able to help any. It can be done!
PM me if you cant find the drivers mentioned above I can email them to you.

Thanks for the quick response.
Can you just confirm that you were connecting using the blue Male-Male USB cable, and not a USB-Micro-USB cable?
When I connect to the Micro-USB port it doesn't see a device at all. It just seems to provide power.
When I connect with the blue Male-Male USB cable, unless I have "Connect to PC" ticked, it also doesn't see a device.
I don't have a micro-SD card installed, but that doesn't matter right?
I'll try those drivers you suggest. Thanks.

I am quite keen to figure out what is different but I cant access it for a couple of days sorry.
I definitely used a full sized USB to Connect, I may have used another one, and powered it from the Micro USB direct to power supply. If you are connecting it to the PC for power it may cause problems.
I know that you cannot access the recovery menu unless you are powering through the Micro USB only. Another thing I meant to mention in my original post. I may have posted it elsewhere.

SUCCESS! After I got the SuperOneClick software to forcibly install the drivers the device was then recognised and I could root the device.
Thanks. I'll write up the full instructions.

Excellent!! Thanks for writing up the guide.

OK, here is a full step-by-step guide for getting this to work:
Download "SuperOneClick" from Download.com (CNET). I can't post external links right now because I'm a new user, but it will appear if you do a Google search.
Extract SuperOneClick to a temporary location ("C:\temp" for the purpose of this installation).
Download the software from the link in the first post above. On the "Share-Online" page click the small-ish button that says "continue for free", and not the big "DOWNLOAD FILE (regular download)" button in the banner ad (that I feel very silly for clicking several times).
Once the file "RK3188_ROOT for CX-919 FW0715 MOD by Everal.zip" has finished downloading, extract it to a temp location on your PC (for the purpose of these instructions "C:\temp").
Make sure the Micro-USB port of the device is connected to a power source (ideally the provided AC adapter). The port doesn't seem to transfer data so don't connect it to your PC, unless you are using your PC as the power source. Basically as long as it's turned on, then continue.
On the Agora device, go to "Settings", open the "USB" menu, and enable "Connect to PC". Without this the device wasn't recognised by my PC at all.
In "Settings", click on the "Developer options" menu, and tick "USB debugging".
Connect the provided blue Male-Male USB cable to a full-sized USB port on the device, and to a USB port on your PC. At this stage the device connects but is not recognised.
Open "SuperOneClick"
In SuperOneClick click the "Advanced" tab, then click "Check Drivers".
When prompted to ask if you would like it to forcefully install drivers, click "Yes".
Click the "Install..." option when prompted by "Windows Security".
You should then hear the device connect, and disconnect, and see an message "Driver installed! Please reconnect your device", so click "OK".
Disconnect the blue USB cable from you PC, and then reconnect it. You should hear that the device has connected successfully (and it now appears as "Android Composite ADB Interface" in you "Device Manager" if you care to check.).
Open "Command Prompt", by right-clicking on it and clicking "Run as Administrator". (I found that running the .bat file directly failed because it didn't find the "adb" application)
C:
cd temp\RK3188_ROOT
TPSparkyRoot.bat
Follow the prompts from here. The application should reboot your device several times (if not something is wrong), after which point you press any ket to continue. From here everything was very straight-forward once the .bat file completed the device was then rooted.
Enjoy

I had to do things differently......
Used rocketchip_batch_tool_1.7 for drivers, superoneclick didnt do anything.
I ran the batch from the folder on my desktop.
For EACH device re-boot i had to RE CHECK connect usb on cx919 settings.
I got a few errors about no more storage on my device when it tried to copy some stuff, although i have the super user and i tried sixaxis controller which requires root and it worked. Not sure what the files were.
update:
Hmm and it seems SSL websites dont work now as well as Netflix or the Store.
ill have to try something else!
Update:
did a factory wipe. all seems ok now.

Worked fine since then. All a sudden same prob, no Netflix no store. Wtf?

Just wanted to post an updated root method since i got one of these second hand last week
1. get the universal rockchip drivers, or the latest generic google ones. both worked for me on two different PC's. (including windows 8.1 x64)
2. Enable USB Debug mode in developer options. you know the drill.
3. the kogan device has a "USB" menu in settings, that has a 'connect to PC' setting. turn that on or ADB cuts out shortly after the system boots - turn it off after rooting for it to work normally.
4. connect PC to kogan dongle via the USB port next to the power LED. The other one doesnt work.
5. root with whatever method you want - i used kingo root which rooted it flawlessly first time.
6. have fuuuuun!
3 and 4 stumped me for days til i figured out what was going on. not something i'd ever encountered before, and likely unique to this device and why some people cant figure it out.

Yu Yureka USB Connection Problem
