I have just flashed it
MD6 stock ROM and stock boot images are required. Also there should be nothing deleted or modified in the /system directory (having superuser.apk, su binary, and busybox are okay). So you will need to restore /system if you have modified anything. If you are not able to restore your modifications in /system than KIES restore is the only way I can imagine.
Here is the procedure:
- copy the update zip in the previous message to /cache if your phone hasn't downloaded it yet.
- I have built the following flashable zip that will restore original boot image. Go to CWM and flash this.
MD6 stock boot image
- reboot into stock recovery or CWM recovery
- flash the update zip
- reboot into MI2
Everything will be restored but apps, data, and settings will be preserved.
I will be working on the recovery and kernel for rooting this again. I will let you know soon
Edit: stock recovery was not really require based on the sanjuro's feedback below. So this post has been updated accordingly.
