Maybe I could get you to send dumps of this device it be nice to get to the bottom of why the the updated version doesn't work on this device.

why the the updated version doesn't work on this device.

Perhaps because the new version lacks the table mount points in recovery.zip/etc:

Thanks for the great work!!

Give me moment I like to get the dump of fastboot.img recovery.fstab should be generated from the fstab droidboot / fastboot uses to handle partitions I'm making changes to the recovery.fstab generation so like to include fixes for this if their using other name or something.

If you could this should dump boot recovery fastboot and system

I saw that when starting new version generates mount point right (mmcblk1p1) but fails to mount internal sd card the same. I added recovery.fstab in recovery.zip/etc and your new version 12-29-2014 works without problems!
All versions of yoga 2 (8,10,13) there year numbers and partitions sizes equal ..


For the kernel, recovery and fastboot, I had to use:

dd if=/dev/block/mmcblk0p3 of=/sdcard/boot.img
dd if=/dev/block/mmcblk0p4 of=/sdcard/recovery.img
dd if=/dev/block/mmcblk0p5 of=/sdcard/droidboot.img

Download dump_yoga2_830L
This is full stock firmware

Can we use this to dual boot with Yoga 2 tablet with Windows?

First you have to have the dump of bios..

 

[redhern]

Is the bios available? I havent seen it mentioned in any of the posts.

BIOS is present here but you have to know where to put. And then the windows do not care so much - I want CMmod
Here the guide for ONDA V975i
I do not want to risk (I've already lost imei on my 830L) with these experiments

successfully rooted but... no adb root nor adb remount

Hello,
I successfully rooted my 1050F device following this guide
Now I'd like to run adb as root and to be able to remount rw /system to put and remove staff there but the usual method don't work.

I tried adb root and adb remount but lenovo adb cannot run as root in production build.
I tried installing adb-insecure 2.0 which usually do the trick but when I patch the kernel from the app and use adb insecure demon the device is not seen by the PC with adb .

I also tried to remount with "sudo mount -o remount rw /system" but I cannot write in the /system partition

any suggestion?

thanks,
Dario

adb shell
su
mount -o rw,remount /system

 

[blackdir]

adb shell
su
mount -o rw,remount /system

sure, that will work, but if you need to push several files it is very tim consuming as you need to copy to a temporary location on the device and then move them to /system

if you are able to get adb insecure you can create a batch file that you can run from the PC

Any idea about the reason why dab insecure is not working on this device?
Is it because the device is intel based and not Arm?
(if this is a stupid question, please forgive me as it is my first experience on Android Intel development)

Correct you need a adbd binary for intel fully rooted meaning its always root, or you need to have an unlocked bootloader, that allows flashing of modified boot.img.

 

[xterminater07]

I updated the system via OTA and root again but it said Failed: too many links or something like that but it continued and cwm is installed. Is this ok?

 

[djf2k6]

Have you tried flashing the bios yet or did you find any other ways to run windows on this tablet?

bodivas, could you post a guide on how to install windows on external sd card? The guide you posted when translated to english it is very hard to understand, and the onda is built on a different chipset, slower ones, so we would need to find intel baytrail drivers for it to work right. Also would the bios for the 1050 work on the 1350?

 

[JansenJohansen]

Rooted my Yoga 2 10" with the Jan. 10 OTA update installed, worked like a charm and the next best thing to a one-click root for noobs like me!

Thanks!

 

[Paran[dr]oid]

Here the same. 1380F with last OTA and root is rock solid [emoji106]

 

[jesusCris]

I have a problem

After I root my YT2-1050f, I can't enter recovery mode.
