Lenovo Ideapad K1 One-Click Root (Mostly)

---

First, please forgive me if this is posted in the wrong section. It seemed most appropriate.

Second, I take no credit for anything here except for writing the .bat file here used to do the work, as well as assembling the files as per the original post.

All credit goes to djmwj and his article found here:

As the title states, it was very messy. The OP figured out how to make it go, but it was a bit fuzzy to follow. So, I thought I'd help folks out a bit and clean things up.

So, I took the instructions presented in the OP, and condensed them into one download with one .bat that does everything from start to finish, minus installing the respective drivers for ADB and NVFlash. However, the drivers are included in the download.

Instructions:

1. Extract K1Root.rar to the directory of your choosing.
2. Connect your tablet to your PC with the USB cable.
3. With your tablet off, press POWER+VOL_UP+VOL_DOWN until the screen turns on, but displays only black.
4. Windows should detect the device, but not install drivers.
5. Go into device manager, select the APX device, choose update drivers, and install the drivers from the aptly named NVFlash_Drivers folder.
6. Open up the NVFLASH_HOME folder and run the file K1Flash.bat
7. Make your desired choices when prompted, and enjoy.

Notes (PLEASE READ BEFORE USING):

THERE MAY BE BUGS! I used it on my own stuff before releasing, and all of the essential components work as they should, however, there may possibly be a minor hiccup somewhere in the script. This should not damage anything. If you have doubts, you're welcome to examine the .bat and check it for yourself.

Please be gentle. I am not a full-time developer. I just wrote this to help make the process simpler for people.

The OP suggests you download and read the partition table, and then name the backup files based on that. This script names the backup files based on the flash.cfg script referenced in the OP, which is what controls the flashes used anyway. So, there shouldn't be any irregularities, however, I can't speak for every device on the planet.

This does NOT use the latest OTA updates. The rooted files being flashed are the default ones from the original download. You can easily adapt this to any files generated from the latest OTA files by simply dropping them in the NVFLASH_HOME file.

To install the SU properly, you have to install ADB drivers midway through the script. There's probably a way around this, but I didn't find it to be too inconvenient.

The ADB drivers are also located in the NVFLASH_HOME folder. Just do like you did when installing drivers in step #5, but instead point to NVFLASH_HOME.

Um...um...

That should be it. Obviously, use at your own risk. Let me know if there are problems with the script, and I will fix them.

Oh, and party on, Wayne.

EDIT:

Attached is an updated .bat file which fixes a few errors in the original script, plus adds more userability. Just extract to the NVFLASH_HOME folder and run.

You may want to change the title to Ideapad K1, I don't know if this will work for the Thinkpad tablet.

Thanks for this, I just picked up this tablet ($250 at staples) and was worrying about having to tackle linux and "compiling" just to be able to get hulu.com working. You're a lifesaver.

Wow. Yeah, I'm pretty sure the key used is just for the Ideapad. Thanks for pointing that out. My dumb a$$ must've blanked out and just used the group name when posting.

And just to be fair, the original poster does include everything needed to do stuff in windows as well - it's just very hard to discern from the post.

Is anyone working on a custom ROM for this tablet? I am hopeing that there will be at least a few custom roms available at some point in the near future.

We need to be able to root and unlock the bootloader first.

Does the root method work on the 121211 update?
Or is there a way to flash back to the older firmware?

the OTA update 12 12 11.... seems to be update.zip style with no .img files inside. just loose files like normal rom updates. doesnt seeem like you can drop the files in as suggested. or i have the wrong OTA....

oh and is this for LINUX as the OP or work in windows too??

Hi, I was wondering, is this procedure works for the Lenovo ThinkPad 1838-25U? I'm thinking to buy it to give a test ride, i sold my Transformer 101 to buy the Prime but it seems like Asus is taking vacations on the delivery shipments. Is this a good tablet? or is better to wait for another version?

READ THE POST

IDEApad not THINKpad. no it wont work.

First of all- thank you so much for creating this script! I have been putting off rooting this device due to the "messy" nature of the original post.
I was hoping you could help me troubleshoot, I have tried both the new K1 root application and the original .bat file. I know the drivers are working because the script makes it as far as creating and formatting partitions and successfully pushes the bootlooder.bin but then:

bootloader.bin sent successfully
file not found: recovery.img
failed executing command 2147483647 NvError 0x4
command failure: create failed

I've tried everything I can think of... any ideas?
Thanks again.
