Temp CWM-recovery

1. Download and put the UPDATE-SuperSU-vX.Xx.zip on internal/external SdCard
2. Download, extract the folder IntelAndroid-FBRL and put on the C drive
3. Follow this guide (Use the option T3)

This is new version fixed by social-design-concepts (Please support its work with donations)
Now backup kernel with recovery too:

IntelAndroid-FBRL-01-17-2015.7z

Root, backup & restore on the external card works well:

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

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:
Code:
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

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
