[Miscellaneous Android Development] gmarkall:
This version of ClockworkMod recovery has been produced by Milaq

There's currently a github repository for the device/lenovo/a1 folder in the Cyanogenmod Android tree at https://github.com/gmarkall/android_device_ideapad_a1

Current status: CWM v6.0.1.2 by Milaq

Download: http://milaq.exnet.me/downloads/android/a107/cwm-6.0.1.2-ideapad-a1.zip

What appears to work: backing up, erasing and restoring /system, /data, /cache and /sd-ext. Installing zips from internal and external SD cards. Touchscreen calibration. Partitioning the external SD card. Installing OTA packages also works, but they will wipe out this recovery

What's not supported: backup/restore of the x-loader, u-boot, kernel or ramdisks.

Installation of 6.0.1.2 from the stock recovery

WARNING/DISCLAIMER: Although the recovery has now been tested by several people and there have been no problems reported, there is still a small risk of damage or problems due to unforeseen issues. The unlikely worst case scenario is that your A1 will be bricked. In the event that something goes wrong, I will do my best to help recover the situation, but I am not liable for any damage incurred. It is up to you to decide if you want to take this risk. If you are not comfortable with the risk, then do not attempt to install the recovery!

Now that's out of the way, and if you're willing to take the risk, the following steps should be taken to install the recovery:

1. Download the file "cwm-6.0.1.2-ideapad-a1.zip" from the hosting page.

2. Copy this file to the root of the internal SD card and rename it to update.zip (so the full path should be /sdcard/update.zip)

3. Power down the Ideapad.

4. Hold down volume down and turn the power back on, keeping volume down held until the tablet boots up to an image of an arrow out of a box with an android (this is the stock recovery).

5. Wait whilst Clockworkmod recovery installs. The progress bar should fill up.

6. Once the installation has finished, you should see a green tick in a green triangle and the ideapad will power down.

7. You can now power on as normal to get back to Android, or power on with volume down held to get into Clockworkmod recovery

8. Please post your experiences, and any issues you encounter in responses to this thread - feedback will be really helpful to smooth out any issues, and/or to gain confidence that the recovery is working properly.

Installation from an older version of Clockworkmod

If you have installed a previously released version of of this CWM, you can install the latest version in the usual way in which zips are installed in CWM.

Going back to stock

You can install the stock-a1-recovery.zip file using Clockworkmod to go back to the stock recovery.
