You can now root your Hudl! :) YOU USE THIS TOOL AT YOUR OWN RISK! We take no responsibility for any problems caused. Pre-requisites are as follows: A computer running Linux (a live CD should work)

Hello,   this unfortunately did not work for me. BUT you can try this: http://www.mgyun.com/vroot   This actually works, it will detect your tablet (as it is Archos hardware) and apply a Chinese

You can do it from Windows, ADB works on all desktop platforms. Just setup ADB and then type all the above commands at a command line (Start>Run>"cmd.exe").   Alternatively, and probably much

Hi

 

Has anyone had any luck using the Kingo tool with Windows 7 x64?  I ask because although the tool runs it does not detect the Hudl.  The Hudl is showing in Device Manager as 'Other Device' and has no drivers installed.  Is this because there are no 64-bit drivers?

 

Will Windows Xp work?

 

Many thanks for any guidance.

 

Paul

 

You need to install the driver from the RKTools in this forum in another thread. Definitely work, I've just rooted mine again this evening (I had used the chinese one but it was playing up a little)

I tried the Chinese rooting software and this downloaded a driver for Samsung Mobile Phone - ROMaster Composite ADB Interface.  It then proceeded to root the phone with Chinese SU.  Despite my best attempts, I  have been unable to replace the Chinese SU with Superuser, which installs but will not 'take over'.

 

I then turned to Kingo and used it to unroot.  This suceeded and removed the Chinese SU and SuperUser.  I then used Kingo to re-root.

 

Now the strange thing is that all root apps work fine including Root Checker, but Superuser wil not update and shows no apps in its permitted list.  Output from superuser update is as follows

 

Downloading manifest – okay!

Parsing manifest – okay!

Latest version = 3.1.1

Checking installed version = 1.45:SUPERSU

Fixing database – okay!

Unpacking sutools – okay!

Checking current install path - /system/bin/su

Downloading new binary – okay!

Gaining root access – okay!

Copying su to /system – okay!

Changing su file mode to 06755- okay!

Making sure new su works – fail!

 

All ok until the last line!

 

Does anyone know what is wrong?

 

TIA.

I have tried the Chinese VRoot program with the same results - hudl is rooted, but the su which is installed then won't allow itself to be  overwritten/updated (same log messages as above).    It will do for the time being, but I'm uneasy about running an unknown Chinese app at su level.   This might be a backdoor for anything. 

 

I tried booting a Ubuntu disk and doing it properly by Paul's method, but the complexities of linux defeated me.  Hopefully there will be an idiot guide soon, or a trusted Windows app.

Have a look at my method, that I posted a while ago... I threw it out there before even getting the Hudl. Now that I got one, I can confirm that it does indeed work. Its easy, listed how to do/use it... and bonus part, its all in English ;)

Cheers, Lister

Yep - the Kingo app definitely works once your PC has drivers.  I think I need to play a game of 'Hunt the SU' to try to get rid of spurious installs.

I have now got it working properly.  I used Kingo to un-root.  Then I searched for any surviving instances of SU.  It seemed to have been placed in /system, /system/bin and /system/xbin.  I removed all leftovers and rebooted.  I then used Kingo to root which succeeded.  Kingo injected SuperSU instead of Superuser and this seems to work perfectly.

 

In summary, I recommend Kingo for rooting but you will need the ROMMaster ADB Composite Interface drivers installed first.  I assume that is what installs from the RKTools package.

Have you enabled USB debugging?

just a note ive extracted the file to the desktop, terminal does not recognise that as a directory,as im new to terminal commands what 

should i type for termnal to execute the sh file ? would it be close to  'home/desktop/hudl.system.withsu.20130923.020558.r2 sudo ./flashroot.hudl.linux.sh' ?

Make sure you are typing "sudo ./flashroot.hudl.linux.sh". From your post, it looks like you may have left out the sudo.

 

If that's not the problem, maybe try typing "chmod +x rkflashtool-linux". If that command doesn't work, try the same command with "sudo" at the start.

Has anyone tried rooting the new hudl firmware (got a replacement due to faulty mic, build number is JDQ39.20131016.200812)?

 

EDIT: kingo works fine for this.

I am quite confused which usb driver i need to root the hudl using kingo or the chinese rooting program, anyone give me a step by step for windows , i am using windows xp, and my hudl is the right version.

 

Also when i select unknown device to update driver in device manager and i select the rktool driver folder it says the specified file doesnt have information of your device (the hudl is currently on at this point when i did this with usb degging on), anyone know how to fix this?

Kingo worked for me eventually, after I'd downloaded and unzipped the huge Android SDK (cut-down version apparently available) and when the next driver install failed as ever, pointed it manually ('have disk') at "sdk | extras | google | usb_driver" and within that to "android_winusb.inf" (...long anxious wait).  That worked on Win7Starter, I hadn't got drivers right on XPpro.  My previous failed efforts had loaded the elderly MTP drivers from Microsoft, and opened the sdk via Eclipse, either or both may be needed, maybe not.  Couldn't see what to do with RKtools, or Archos drivers.

 

The Linux method at the start of this thread didn't work for me on Mint32 or Mint64liveCD.  Terminal wouldn't run the instruction (with su, and extra chmod), even though dir confirmed directory content.  Got furthest on the 64-bit kit, using the bash lines from post #43 above, but then each line of the following script threw an error.  Not an expert in terminal!  And how does it know which USB socket to use?

 

The Chinese method counted %s first, then showed some sort of activity bar forever.  Not enough Chinese to investigate!

 

Persistence pays, and it's certainly educational...

Why wouldn't you just Google: "ADB driver installer", instead of downloading 400Mb+ of stuff you don't need... :S

Thanks, Paul - worked a treat. Although it's mentioned later in the thread, it might be worth editing the top post to indicate that the rkflashtool executable in your download link is 64bit (I had to compile a 32bit version for my use)?

 

 

Hey @~pmv could you share your 32bit version ?

 

Thanks in advance..

Have to say I tried this, using the adbdriver and on my PC, I could not for the life of me get it to recognise the Hudl with anything but the microsoft driver. I am no slouch when it comes to PC's but no matter what I did to uninstall drivers etc it wouldn't work. Luckily for me, I have a laptop, which had never seen the Hudl.

 

I connected the Hudl, let it install the normal driver. Then I installed the driver on their from the adbdriver download. The adbdriver program showed the device as an "Android Composite ADB Interface" (for reference my PC showed Rockusb device - prob after several failed attempts to get the RKTools driver to work, even though device manager is showing the microsoft driver in use!).

 

As others have said once Kingo saw the device, it rooted with no issues at all.

 

Time to start playing  :)

Since Paul is not responding, and hasn't for many weeks (even to PMs), I am creating a warning thread re-directing to his, which notifies hackers of the 64 bit arch of the rkflashtool.

You can now root your Hudl! :)

YOU USE THIS TOOL AT YOUR OWN RISK! We take no responsibility for any problems caused.

Pre-requisites are as follows:

  • A computer running Linux (a live CD should work) - I am currently looking at the Windows / OS X options
  • A Hudl running ROM version 20130923.020558 (check in Settings -> About -> Hudl Updates) - do NOT install on other versions
  • A microUSB cable to connect the Hudl to your computer
  • A pin to press the reset button
To root your Hudl...
  • download this package DOWNLOAD (ROMraid) - MD5: f32f67b3d7942a0d0ec2da3323833813
  • extract the zip
  • plug the hudl in via USB and press the reset pin while holding volume up (the device will appear to stay off)
  • open a terminal window to the extracted directory
  • run 'sudo ./flashroot.hudl.linux.sh'
  • wait for it to complete
  • the device will now go into 'charging' mode, turn it on as normal
  • when the device has booted, install SuperSU from the Play Store
  • try a root app - it should work!
This is just an initial root - if this is too daunting or you don't have access to a Linux box, don't worry, we're working on alternative options. :)

Note that the process creates a backup of your stock system image... just in case... :)

P

PS ROM developers? This flashes a regular Ext4 system image. If you want to mod your device? You can, by modding the image and re-flashing! :)

 

 

Paul, the image is not EXT4, it's EXT3.

Got my 64gb SD card from Amazon as recommended in post #49 above.  Hudl wouldn't recognise it to format it (delivered 'RAW'; Hudl showed only a tiny card icon with an exclamation mark).  Linux wouldn't 'mount' it either.  So I used Windows to format it as FAT32, with 'guiformat.exe' - but Windows only formats to 27.47gb.  So, back into Linux ('mount'...) which recognised it this time, and happily formatted again (as 'FAT') to full 64gb capacity (...'unmount').  Then into Hudl, which at last showed full available space as per the advice earlier in the thread.  Maybe there's an easier way for cleverer people, but this one does work.
