Rooting US K1 --- this method wipes tablet clean

2012-01-13, 20:50 PM

Hi I used this method last night to root my US K1 tablet. It took about 20 mins to do. This method comes from a user timmyDean. Read the bottom of this page to see more information :

http://forum.xda-developers.com/showthread.php?t=1404351&page=5



He also created another method for permanent root and for users with Non US K1 tablets.
http://forum.xda-developers.com/showthread.php?t=1444219


Cool K1_a301_13_13_111209_us rooted K1-V2 - Rooting and Flashing TOOL K1_A301_13_13_111209_US

With some help from (gallahad2000), I've got K1-V2 Root and flash all done. Please read the readme.pdf. Also, note that this tool will erase everything on your tablet. This tool will flash your tablet to the latest US version (K1_A301_13_13_111209_US). It is TOTALLY stock other than root(#).



=================================== Release notes-- V2

http://www.multiupload.com/97J3WS7P1D

===================================

- Fixed factory restore and OTA's - Fixed Superuser and busybox applications - Added back in the additional 'bloatware' user applications which also fixes missing favorites.

The original tool V1, was based on K1_A301_04_04_111017_US and was buggy, plus the rooting process also broke factory restore and OTA's, and the Superuser tools weren't the latest. Plus it removed the default user applications that some people liked

This is TOTALLY stock A301_13_12_11209US with only su, busybox, and Superuser tools. This is what everyone has been wanting. Everything should work (Netflix etc), because it is the latest release.

WARNING: OTA's will download and install which will remove root. So be careful when accepting an OTA. I did not turn OTA's off, so beware updates will break root. I created a backdoor application that you can use to install a backdoor prior to installing an OTA. It is a script and it is in the folder called backdoor (you need adb working). Then you can use the backdoor to get back in and set back up root. But, this should be only done by someone that knows what they are doing. Also, some OTA's reset the entire tablet which also removes the backdoor. So, prior to installing any OTA, you should look at the update and ensure it won't break root and ensure the backdoor would allow you back in as root.

================================================ Flashing none US Stock ROMS ================================================ In theory, you could download a different ROM from http://download.lenovo.com/slates/k1/OTA/ and then replace the boot.img in the tools Image folder. Then, all you'd have to do is mount the system.img (which is also in the Image folder) and replace the files with the ones from your OTA. However, be careful because Lenovo changed the boot blob in 04_04. If you mismatch the boot blob, your tablet will just loop rebooting and rebooting. ================================================

//////////////////////////////////////////////////////////////////////// I could make a flashing tool to flash back to TOTAL STOCK with no root. Let me know if anyone is interested in that? I have K1_A301_02_02_110725_US.zip flash I could post. This would allow you go back in time to stock and then roll forward using OTA's. You could even download a different country OTA (as long as it's newer) and manually flash a different stock image. //////////////////////////////////////////////////////////////////////

Hope this all works for you, TD Last edited by timmyDean; Yesterday at 07:09 AM.

It's such a good news.  Thanks for informing us, monilall11!  I am anxious to install Chainfire3D on my K1.  Wonder if it's easy to undo the process if something breaks?

The only thing I would suggest is to make sure your tablet is at least 50% charged before attempting to flash the device. The only reason I say this is because the tablet does not charge through usb when connected to the computer and the time it takes for your device to take the new ROM might be longer than when I did it . My tablet was at 45% power when I flashed last night.I spent about 10 mins installing the nvidia APX drivers to my laptop and a further 10 mins to flash the ROM to my tablet.

For me it was for backing up my apps with Titanium backup because you need root access to fully backup some apps. Also i have full access to my data folders so i can modify these files that were hidden before.

If you want more info read this article:

Thanks monilall11!  I just rooted my K1 successfully the past weekend.  The process was pretty much automated and painless.  I can now use Startup manager, AdFree, Titanium backup, Samba file sharing and Chainfire 3D.

Thanks for the update. I have been wanting to root it, but still want to have the option to update to future Lenovo releases.

Will look into this more.

Hi,

 

I am using the rom "K1_A301_12_12_111221_HK.zip".  To root my K1, should I 

 

First, replace the "boot.img" of "K1-V2" by those of "K1_A301_12_12_111221_HK.zip"

 

And then, boot to recovery and flash my K1 by your tool "K1-V2" according to the following url:

Thanks for your helping!

Is there a way to disable OTA update? I do not want accidental update to remove the root.

Very interesting. I recently installed Avast Internet Security...part way. There were a few items that indicated the need to be root to get full functionality. I'm not sure I want to root my device. I had  Nook Tablet and was pretty happy with it until the day B&N decided to block me from sideloading non B&N downloads. They took it back and for $30 more I got the K-1 at a Staples in Massachusetts.

Very happy to have regular Android Market. Am learning to like Honeycomb after using Gingerbread on my phone for a year plus. Not sure I'm all that excited about getting ICS and haven't heard if Lenovo will be doing an OTA update, or any other kind of update. If Lenovo doesn't do it there's always CM9...eventually.

I did root a refurbished Nook Color and install CM7 on it for my daughter and she's happy. She was overseas when I got the B&N "security update" that was the last straw for me. I emailed her to turn OFF automatic updates before she gets back to the States or she'd probably have the same fate as I did with the Nook Tab.

Is it device specific or do those OTA updates always remove root from any Android device?
