Goodmornig everyone..!
I just bought an Archos 80 G9 Turbo 16GB and I cannot connect it with my computer that runs Windows 7 64bit
When I plug it, it is detected as an Unknown Device (error code 43) and nothing is mounted.. (but tablet is in "slow charge")
In an old Win XP computer is working good, this made me think it's not completely tablet's fault..
here what I've tried, deeply searching on internet:
-Downloaded ADB android Drivers (in Archos site, on internet, various sources), forced installation of them, problem come out: Drivers are not for a 64 bit Os
-Uninstalled Kies, LG Pc suite and rebooted after every change..nothing changed
-Unactivate and reactivate after reboot Windows Media Player 12..no change
-Changed Usb Mode in tablet from MTP to PTP.. nothing changed
-Installed a lot of USB apps in Google Play and tried changing values..no change
-Upgraded tablet from GingerBread to ICS, deeply wiped and restored several times, and in every configuration, I allways had same results..
-Changed USB cable, several of them tested..and guess?? Nothing..eheh
-Tried shouting at it, tried kissing and asking for his forgiveness..but nothing
I'm stuck on Stock! i cannot upgrade it with XDA custom, I can only connect to pc via FTP server....!
Any Clues?!?!
Thank You to all!
1. To root and to enable SDE menu you need only adb driver
2. You can transfer archos.ext4.update files using FTP from pc to tablet
3. Recovery for flashing firmware update or custom kernel creates ramdisk which is seen as standard usb storage device- "just works"
You need to give full access (Everybody) to the folder where Android SDK is installed in Program Files (x86) and through Android SDK Manager select the second item "Android SDK Platfrom-tools for download.
This worked for me on Windows 7 Ultimate.
Ooops overread something... forget it!!!
Have you checked for the correct MTP driver package...

Only is an huge word, I have tried several dof them, and no one is working, no one is accepted by windows (it tells me they are not designed for the device or they are not for an x64 OS)
Strange thing, it accepted me usb drivers for Samsung Mobile, it installed them.. but not ADB from android... obviously, Samsung ones where not working with it..

Dowloaded and istalled a few from windows... the problem is, if it would be an MTP problem, I should not have it in PTP mode... I suppose...
EDIT: tried disabling Integrity Checks for non signed drivers with these string in cmd:
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON
nothing changed

These are the first one I tried.. From their site.. Not working.. Thankyou!
I wrote them in Contact and support in that site, copying and pasting the same I wrote here, they answered me, two days later.. Excited in what solution they could give me,from the heights of their knowledge, I suddenly opened and the answers was:
Please write the email in English.
Are they kidding me? This makes me suppose they have not even tried in reading it.. Well.. 1000 thanks for you and you support..!

Second reply from Archos, this time they read it, but only first few lines..
their reply is:
"We invite you to connect the device to a 32 bits system and then to check if the Archos is seen by the pc."
Already done, and it's working with that (WIN XP)
Did you try to install manually the MTP driver from the device manager of the PC ?
YES.
any new clue from here?
Thankyou!

1 thing, when you are plugging into your PC, are you plugging it into the main hub (rear of PC), or a front port?
I had a devil of a job getting mine to recognise the driver, in the it turned out it really needs to be plugged into the rear port, it may have been a conflict on my PC, but worth a shot.

Yes, tried to connect it in every usb my laptop has, even tried in disconnecting every usb device and turned off the pc. After that I took off battery for a few minutes and started again.. no change... ERROR 43...!
In the old win xp pc I use front usb I installed 10 years ago, and works..!
ADB USB drivers from archos site are not recognized, it's not possible to manually select them.. I was able to select an old symbian driver I have in an old backup directory, but not that one... any clue?

Did you try the link in my previous post? I'm running win7 64 bit and it worked for me!
Maybe just try adding the file in your USERPROFILE directory first!

Yes, that one and a modified one.. the problem is, it remains as an "Unknown Device" (error 43).
I tried now to move that driver you suggested me in USERPROFILE (c:\USERS\"myname" and c:\USERS\"myname"\.android) is this you mean?
and same error: can't find in directory any compatible driver for the device. make sure it's done for a x64 system...
It seams to me device is not recognized at all.. not PTP or MTP or USB DEBUG....
but it works with win xp...! I tried again..!
Another doubt I have is: when I plug it to the wall charger I found on the box, it goes on "Slow Charge".. is it normal? why not fast charge or Normal? may be an hint?

OK try this :-
Download the naked universal drivers attached to this post and unzip somwhere!! (got this from the Sensation forum, would say thanks but I can't remember who posted them).
Attache your G9 then go into device manager.
Now find your badly installed driver and uninstall it. Keep doing this until all drivers are uninstalled.
Now unplug and reattach G9, let windows do it's thing. You will still have a excalamation next to "Android Drivers" at this point.
Right click on the driver in device manager and "Update Driver Software", then click "Browse My Computer....", now click on "Let Me Pick from a list...", then click the "Have Disk" button. Browse to the folder where you extracted the Universal Naked Drivers and select the andorid_winxusb.inf file.
If you get unsigned warnings click on the "trust me" or whatever it says.
Driver should now be installed.
The adb_usb.ini file is really for if you use adb, if you do it need to go in c:\users\you\.android directory (create the directory if it doesn't exist).
You can test adb connectivity by using "adb devices" from the command line.
Hope this helps

I think this is probably because your USB cable only has 2 internal cables, not 4.
IIRC, the outside 2 are USB and data chat and the inside 2 are for 5v power.
If your G9 detects the cable doesn't have the two middle connections then it will do a slow charge regardless.
Are you using the cable you got with the G9??

Yes, I'm using the cable i got with the g9.. I could have a dual cable (the one they give to you with an external hdd), but it's mini usb, not micro...

And this is the problem.. I don't have any driver to uninstall, as if my device is an "Unknown Device" no service, no adb no mpt recognized.. only an "unknown device".. even with new drivers, the only driver it lets me install are Samsung drivers.. but obiously doesn't work!
I now tried in installing it as this samsung, just to have something to uninstall...

You are really amazing, archos is not caring at all..
Before I tried your firs suggestion in USERDEVICE and for a minute it found my device as Error 10 and not Error 43 (unknown device)... and that's the only moment my pc saw the tablet...
Thankyou!!

I too have run across this problem--AFTER woprking for 6 months with it under ADB just fine. Not just my work computer, home devices as well. Did you ever get this fixed?
Ok hopefully this helps someone. After flashing the amazing AOKP ROM (literally best ROM I've ever flashed...Holy stable batman) I noticed that on Win7 x86 or x64 that USB file transfer to/from SD card worked fine...as did Odin but Windows could not find a driver for my phone anymore. This creeped me out because this meant adb would not be able to connect. Running the adb devices command would not show anything.
I tried 3 different Win 7 machines and a WinXP machine all of them used to work but now they didn't I read the FAQ, I goggle searched xda and droid forums and tried everything, cables, switching USB ports, phone settings, dev settings, new usb drivers but, I could no longer get adb to connect.
So I started looking closely at the Samsung USB drivers I have on my machines which worked fine on stock ROMs, and a few other custom ROMs (not blaming AOKP no disrespect) and I found that the hardware id for my device changed and the device string wasn't referenced in any of the USB drivers files. So I forced the correct driver to install and it worked! So if that is all you need to know cool, if you some of you need the steps here they are:
I'm assuming you already have Samsung USB drivers and adb from the SDK installed (if not there's tons of info on this site to get both)
I'm also assuming you installed the USB drivers so they are in the default location, if you extracted a zip file or something you will need the path to the USB drivers
Last assumption... I tried 3 different versions of Samsung USB drivers and for each one the ssadadb2.inf that has the ADB driver was in the USB Drivers\16_Shrewsbury folder...If you don't find it there do a search in the USB Drivers folder and reference that location for step 13
Click Start button, then right-click Computer, then click Manage
Click Device Manager
Expand Other devices, you should see SCH-I500 with the yellow exclaimation point
Right-click it then click Update Driver Software
Click Browse my computer for driver software
Click Let me pick from a list of drivers
Scroll up, highlight Show All Devices, click Next
Click Have Disk
Click Browse
Browse to C:\Program Files\SAMSUNG\USB Drivers\16_Shrewsbury
Double-click ssadadb2.inf, click Open, Click OK
Highlight SAMSUNG Android Composite ADB Interface, click Next
You will get an "Update Driver Warning" saying cannot verify compatibility with your hardware, click Yes
You should see Windows has successfully updated your driver software, click Close
Back in device manager under ADB Interface you should see the driver name you just added....the entry under Other devices should be gone
Connect your data USB cable (not a charging only cable...if you can't tell the difference just be sure you used this cable for data before)
Open a cmd prompt (start>run>cmd enter if you didn't know)
browse to where you installed adb and type "adb devices"
You should see your device and a serial number again....back in business
Like I said no disrespect to AOKP I rock my B31 (soon to be 32) Pink Unicorn proudly This hopefully applies to anyone who had a hardware id change from any ROM.
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:
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

So I have a Samsung Vibrant(just got it recently) and I'm having problems when i connect it to the computer. It gives me an USB device not recognized on my windows 8 computer. I have spent all morning searching and reinstalling drivers and trying my old pc and new cables and i found out that my old windows 7 computer with 4GB of ram and an overloaded hard drive will detect my device the problem there is it not my main computer and i dont want to have to connect all the vga cables boot it up connect mouse and ect to use this computer just to be able to copy files, and do other things from my computer to my phone I dont know why my main computer dell inspiron windows 8 will not work when it was a couple of days ago when i had a problem with conectivity and had to flash back to stock but now it wont connect. could someone help me? Here's a list of things i've tried
installing kies
installing adb again
aoi tool and then drivers
a bunch of diffrent drivers found on the fourms
diffrent usb cable
i would like to be able to do it on my main computer but its not working if someone could help that would be great
also please dont hate on me for having windows 8 jk i dont care :good:
I'd have to say that your drivers are all scrambled. Look up "android SDK" here on xda and install that for a bigger variety of drivers. Or just download Google's USB driver and manually install it through device manager which always works for me. Windows 8 is new and very complicated.

Android SDK is installed in the main drive right? local disk c?
You have to click the folder (usb_driver) and then click update.
In the android sdk folder there should be and exe file called SDK manager. There you will be able to download all the drivers for your current android version also the latest Google drivers and SDK tools etc.
I was stuck on this process for a long time because it allways works different for everybody. Just keep me posted on what you do I'm more than glad to help.

So what exactly happens when you click update? What does it say?
Is your PC up to date? (update wise)
Do you have the the drivers for the phone itself like samsung drivers?
And did you try rebooting your PC after installing your drivers? <-- that is important. You should always reboot after install or uninstalling drivers otherwise you'll end up scrambling them.
From the pictures it shows you have the drivers but I'd also try going deeper than usb_driver, try clicking on i386 or amd64.

OK make sure there are no HTC drivers on your PC. When you hook up your phone does USB storage work or anything like that?
Check those out and then I want you to go to Google, download pdanet latest version via pc (dont install yet) and go to the play store and install on your phone turn on USB debugging and the install non market apps and hook your phone up to the computer. Then install pdanet via PC and see if that works. HTC drivers get in the way of Samsung's BTW.

I want you to uninstall all your Samsung drivers(not android SDK) under control panel/uninstall programs. If you see something like Samsung kies definitely uninstall it. Reboot your computer and follow this guide for windows 8:
http://forum.xda-developers.com/showthread.php?t=2038555
After this if it doesn't work I'd recommend pulling out your old computer for android modding lol. I'll still look up some threads for your problem. Let me know what's going on after that. Make sure when you follow that guide your phone can not be plugged in the computer. And when you plug your phone into the computer after everything is done and after you reboot your computer for the second time, USB debugging has to be off and when phone is done unplug and turn back on USB debugging and plug back in and wait for that. Adb should work.
[Edit] you can also try running your drivers in windows 7 compatibility. Sorry I couldn't help much.

I think I know what the problem is. Make sure you uninstall all the previous drivers, then have the correct drivers ready.
What you have to do is to disable driver signature enforcement.
Step 1. Go to the right bottom corner of the desktop and wait for the side menu to appear. When it's there click on the gear icon with the title "Settings".
Step 2. Now click on the entry "More PC Settings", then click on the entry "General".
Step 3"Restart now" (under "Advanced start up ") and click it.
Step 4. Now click "Troubleshoot", then "Advanced Options" and after that click "Windows Start up Settings".
Step 5. Click on "Restart" and wait, then on the next screen press F7.
You will now reboot, and try now to install the drivers (by manually selecting the folder in device manager).
I'm not sure what is the correct drivers for you.
But try this. It's still worth a shot.

Now again I am using Windows 7 so the steps are almost exactly the same. I literally just changed the device to a USB Mass Storage device and it worked!
Lol after trying so many drivers and it being the generic driver makes me angry. Here's what I did.
1. Right click on My Computer, go to Properties.
2. Go to Device Manager
3. Find your My HTC (should be the second one Android USB Device), right click on it and select Update Driver Software
4. Then select Browse My Computer for Software
5. Then choose Let Me Pick which driver to install on the bottom.
6. Then choose USB Mass Storage Device
Then it takes some time to think and viola! All working! However we are not DONE!
EDIT: So the next step I did after experienced issues remounting after unplugging the phone. I have change the MTP to ADB Testing Interface and things seem to be mounting everytime. Rebooted phone and PC, both worked again so I think this may be a working solution.
Now go to MTP.
1. Right click on My Computer, go to Properties.
2. Go to Device Manager
3. Find your MTP (should be under Unknown Devices), right click on it and select Update Driver Software
4. Then select Browse My Computer for Software
5. Then choose Let Me Pick which driver to install on the bottom.
6. Then choose Google Inc. and the Driver is ADB Testing Interface.
ENJOY!
