EDIT 12/13/2011:


Instructions to Root the le pan tab tc970 from whatid (THANK YOU!!)

"Here are the steps (to root) for newbies.
1. Download the packages from OP (Post #1). Assume you are using windows, you don't need LinuxDriver.7z.
2. Use http://www.7-zip.org/ to unpack onto your computer.
3. On your TC970, hit home->Menu
4. Applications -> Development
5. Check "USB debugging", optionally some suggest checking "Stay awake"
6. Connect your TC970 to your PC, when prompted new hardware detected. Select the Windows Drivers directory you unpacked in.
7. Once driver is installed, run "SuperOneClick.exe"
8. Just click "Root" under the "Universal" tab and wait.
** It will prompt you to install BusyBox during the first time, just install it **
9. When it is done, it will prompt you.

From dbaybay's experience (thank you for your continual help in leading the le pan community through the growing pains!!!):

If you ever have to root your tab again (say after upgrading the firmware), when you root it the first time, open up SuperUser before rebooting and Menu > Options/Prefs and choose "update binaries". Then reboot and your root will stick the first time around.

If everything seems ok, turn off your TC970 by holding on the power button. Power up again, and see if root stay (use Root Checker Basic).

If not, repeat step 6 (no need to install driver again) until you have root after reboot."



Also a big thanks to nehinbin for giving the community insider info with regard to the tablet and firmware v2 which you can find here:

http://lepan.supportsync.com/articles/view/Latest_Firmware_for_LePan_TC_970_Tablet_Computer_11



For the brave or fool hardy, here is a link which will direct you to directions on how to port CWM to a new, as of yet unsupported device (like the 970):

http://www.koushikdutta.com/2010/10/porting-clockwork-recovery-to-new.html


AND HOT OFF THE PRESS FROM cas_xp:

"I am still waiting mine to be shipped. (should be today or tomorrow) Can not wait!

But if anyone is interested, I attached a tool to extract Le Pan update package as
Kernel
ramdisk
recovery
system
...

For somehow, the system is compressed and not yaffs2 or other format. I am trying to figure it out."



~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I have achieved root using a modified superoneclick 2.2 on my Le Pan TC 970!!!!!

Credit to all devs who produced superoneclick and associated root methods!!!!

I wish I could take some sort of techie credit for this, but I did it by swapping the adb file and associated .dlls in superoneclick with some that I procured from *somewhere*. ;)

The root is not permanent, but for someone with far more experience in android than i, i am sure it could be used to develop a permanent root.

If there are people out there who would like to take this to the next level, send me a pm and ill see about getting you the files to repeat what i have done.

-DerKoch

NOTE:

After reboot when trying to gain elevated privileges on the device i get the error:

link_image[1995]: failed to link su
CANNOT LINK EXECUTABLE

Could be a useful starting place.

-DK

EDIT:

Nuts to it. The Superoneclick i modified to gain root is now attached. It is only modified for and works in windows as i didnt feel like farting around with the linux version.

Good luck with the permanent root.

-DK

ANOTHER EDIT:

I have updated the post and am including the missing files.

Dont ask where i got them and, as usual, if you screw up your new toy with anything you find here, i am not in any way responsible. Rooting or altering your tablet beyond what is allowed by the eula of your device will almost certainly void your warranty and piss off the people to whom you are trying to return the device once broken beyond your ability to repair.

YOU ARE WARNED ;)

ALSO, It looks like the tablet hardware was designed by innocomm. you can find this if you download the 4431 update from le pan http://www.sendspace.com/file/sunmks . For some reason the firmware update is not openly available...... Well now it is. Just click on the above link and download at your leisure.

the 970 uses the 3e recovery and what looks like a modified 3e or 2e (i cant remember which at the moment) for the firmware update supplied by le pan.

This firmware package contains a MLO file (35.1kB) which i assume is a shell script (although the text encoding eludes me *encrypted maby*), iboot.ism (131.1 kB) which i think it the, you guessed it, bootloader the tablet uses during the flash process, and griffin.ifw (99.1 MB) which is the firmware. There are a whole bunch of apks included as well so non-market apps are enabled by default and you are told to install them after you upgrade the tablet.

all of the documentation for the 970 is written in mandarin, so for all non speakers, good luck with that :)

I cant seem to decompile griffin.ifw into anything useful, but then again, i am no firmware expert. I am sure some of you would be able to poke around and get it to open-sesamie.

If you are successful, please post how ya done it here so we, myself included, can learn a thing or two.

Best,

DK

Thank you!!

I just wanted to thank you for figuring out as much as you did. I wish I was even on your level but hopefully I will be one day soon. Anyway, you're awesome! :cool:

Edit: I was also able to root my le pan tc970 and it is permanent. It got stuck in a rebooting loop but i just hit the reset button on the back and it turned on just fine. I did have to reinstall all my apps as well but everything is fine now so thanks to you and the developers.

DerKoch, how exactly did you get this to run and root?

When I run the SuperOneClick you posted, it stops responding when it tries to restart the adb server and it just hangs...any thoughts?

Yeah. I forgot to post the other needed files (One might even be able to call them a hardware - software interface if you get my drift. These aren't supposed to be available to the public. ;) ) Im away from my computer, but ill put them up when I get home.

hey dadog,

just search the forums for your phone. the answer is out there ;)

PS

be careful about asking questions in the wrong threads (such as this one). people will rip you a new one and you run the risk of having bad things happen.

Help the community

Hey all,

it comes to my attention that i forgot to post all of the files i have from *somewhere* to make this work. i have what one might call a bleeding heart for people who put themselves at risk to help others and the person who helped me was exceptionally kind in this regard.

please do me a personal favor and call le pan customer support and hound them regarding making the files-who-will-not-be-named publicly available. the phone number is: 1-855-537-2672 (1-855-LePanPC). tell them you are developing software, and have to be able to access the tablet through adb, not just mass storage which regularly fails and screen locks the device. also tell them how disappointed you are with the total inability to use it while it is connected to your computer in mass storage mode, because it constantly chokes on itself and requires a hard reset to get it back up and running. if you are lucky, they might help you out.

if there is enough pressure, i hope these required files will become publicly available and my conscience with releasing these files will become clear.

if you need the other files to get this to work because you are a dev working to open the 970 to comply with the gnu/gpl license they have flaunted by taking the froyo os and NOT RELEASING ANY SOURCE CODE *OR DRIVERS* (GRRRRRRR!!!!), please send me a pm and ill get them to you.

Permanent Root - Le Pan TC 970

Thanks again for the drivers. Now that they are public we can post in this thread instead of PM.

In response to your first post, my device seems to be permanently rooted. I have restarted it several times after the initial root and still retain full access to the superuser bin.

Off topic: The USB wall charger just burned out in mine and I've only had it for a day. I'm going to see if Le Pan would just send me a replacement charger instead of having to exchange the whole product with Amazon. I wold like to get some more hands-on time with it.

Other than that charger issue I find it to be a superb tab.

I have no idea why launchers in the market place are blocked on this device but you can get around this by downloading the apk's and manually installing directly on device.

How exactly did you get a permanent root? Or more appropriately, what was your process for doing it in the first place?

I cannot seem to get mine to root at all

Succesfully Applied Root to my TC970

Makes tablet that much more awesome. It's one of the few Android tablets with a 9.7" 4:3 ratio screen. But, the stock resolution on this thing is wayyy to big. I set it down to 180 with LCDDensity, and it looks great. Thanks for the awesome help folks.

I was having the same problem as you. Actually, when I first rooted, all my apps broke. So, i wiped to factory(on the latest firmware, re-rooted, ran LCDDensity, and was good to go. Then all my apps ran fine, and it didn't lock up on reboot.

Brief Rooting Guide - Le Pan TC970 (Windows)

How exactly did you get a permanent root? Or more appropriately, what was your process for doing it in the first place?

I cannot seem to get mine to root at all

Step 1: Enable USB debugging on device (Settings>Applications>Development>USB debugging)

Step 2: Download windows ADB drivers and modified Super One Click 2.2 from the first post in the thread.

Step 3: Plug in device and install drivers through device manager / new hardware detection wizard.

Step 4: Open modified Super One Click 2.2 (with admin privileges depending on your OS version).

Step 5: Click the "Root" button.

That's it.

I wouldnt hold my breath for a full ics experience. ics is very graphics intensive in comparison to 2.2 and without any hardware acceleration it would be a very slow, somewhat irritating experience.

I believe it would be better to develop an upgraded/modified 2.2 or 2.3 build for the 970 as neither are that demanding in the graphics realm.

Best,

No Official Android OS updates planned for Le Pan TC970

... and that's for permanent root? I just bought one of these from Amazon for $170... so I'm hoping I can root it in the hopes of some ICS magic in the weeks/months to come!

I have confirmed with Le Pan tech support that this tab wouldn't be getting any more official OS updates but they may publish bug fixes in future firmware updates.

In their words:

"The TC970 runs 2.2 which is a completely different platform than 3.0+.

Google rushed its release to compete against Apple so it's lacking a lot of support. This OS is not upgradable to anything beyond 2.2.

Le Pan plans to release a new tablet with a new OS that will come out early next year.

Sorry for the inconveniences, we really wish 2.2 would be upgradable to 4.0 or even 2.3 but it just isn't possible. "

...

"The current model TC970 will not be getting any OS updates but will receive firmware updates when needed."

We are on our own to port 2.3.x on this tab.

So, I ran the root exploit and then tried to run LCDDensity and my tablet crapped out.

I then booted into recovery and just did a complete reset, when I came back to the tablet interface I found that Superuser was still installed, and it was rooted permanently. Weird, but i'll take it! I've since have tested it out and restarted the tablet to confirm that it is indeed permanent.

It is. DerKoch, I cannot thank you enough for the help here, amazing!

Thank you, but remember to also thank the development people over at superoneclick. I just modifyed their application. A lot of hard work went into their program. All I did was have the right tools at hand to make their stuff work with the 970 and know where the current failings were with accessing the 970.

Please don't think I'm being ungrateful, but the Android development community is really a lot of different people standing on the shoulders of giants taking their work just a little bit further.

Le Pan plans to release a new tablet with a new OS that will come out early next year.

I just ordered one of these from amazon.ca too - $170 shipped is an amazing deal! I love how it came on super sale the day after someone managed to root it. That was the first thing I went to check when I saw the new price! :D

BTW it looks like the "Le Pan II" that support was talking about is about to hit the shelves:
http://www.amazon.ca/gp/product/B00...d_t=101&pf_rd_p=1293009622&pf_rd_i=2690953011

1.2GHz dual core running Honeycomb... very interesting.

Does anyone have any plans to try Honeycomb on the TC970? (CyanogenMod7?)

    Hey guys, it's nice to see how many people went out of their way to find solutions in rooting this tablet. I see that a lot of my customer responses are posted on here :)

    Anyways to clear some things up:

    1. TC970 IS STAYING ON 2.2. There is no 2.3, 3.0 or 4.0. The software is completely different from 2.3 and would need to be completely re-written. The team is working hard on a the new Le Pan releasing in Q1 or 2012. It will have Honeycomb upgradable to ICS or directly to ICS. Nothing is set until a official statement is released. I am not sure what is going on with that Le Pan Honeycomb tablet posted on Amazon.ca but I told marketing team to take it down to stop all this confusion. Just disregard it for now.

    2. The 30-pin connector is indeed the same as Apple's. Modifications are needed for them to fit.

    note: add .jpg at the end of link (I do not have sufficient posts to paste links in here)

    Le Pan and Ipod interchangeable 30-pin cables:
    i42.tinypic.com/a2yn48

    Le Pan Cable (Left) vs Apple Cable (Right)
    i40.tinypic.com/2m6mvyt

    note: red circle is where excess plastic is chopped off. These small pieces of plastic are the physical blockage preventing the cables from fitting into the ports

    Le Pan TC970 Port modification:
    i43.tinypic.com/2la7evd

    note: red circle is where a small piece of metal was. I carefully bent it upright with some pliers. With this modification, it will fit any 30-pin cable without any modification to the cable.

    Please be reminded that all modifications and rooting voids warranty of the tablet.

    3. Le Pan does not release any ADB or Windows drivers to end users (not my idea, I nagged them for months) but it seems like you guys found a way around that. Good job!

    4. Boot loader is locked but it looks like you guys got around that as well. Kudos.

    Wish I could write more right now but really busy atm. Hope this information helped you guys out. Really surprised and cool that there is a small community for Le Pan now. I'll try to come back and post more, answer questions, etc, when I have more time.

    Good day

    Firmware update

    Since our servers are experiencing heavy traffic, I've uploaded the new firmware update onto a free hosting site:

    http://www.sendspace.com/file/3qbzea

    Note: I have included the preset apks, user manual, and some other things in this zip file. Follow the instructions from our support website to install the firmware.

    Do not open any new cases requesting the firmware update because they are automatically ignored.
    2
    just to follow-up on the ipod/iphone/ipad cable fitting the TC 970.... the mod you have to do to the cable is to shave off the the piece of plastic nearest the metal footing on the left hand side of the ipod/iphone/ipad cable - assuming you're holding it the position that you would to plug it into an apple device.

    note that this orientation is opposite to the le pan.

    used an x-acto knife and carefully scored the plastic from the top and the side until it came off.
