I've updated my ROM for the A2109 to Jelly Bean.
File: A2109A_MCL0201.zip
Link: https://docs.google.com/open?id=0B1jde5rC0oQGejRIcGUtbl81UGs
MD5: b979e686a5845f64a4e76d53724cbb70
Features:
Changelog:
Version 0201
Version 0103
Version 0102
Upgrading from MCL0102 or MCL0103
Installing if you're running the Stock ROM
I highly recommend backing up your apps and data with Titanium Backup beforehand as you'll need to do a factory reset to install. A Nandroid backup in ClockworkMod recovery would be a good idea too, if you want an easy way to get back to stock.
Notes:
Don't try to install an OTA from Lenovo over this, it won't work. If/when Lenovo releases an update, I'll update the ROM accordingly.
Let me know here if you have any issues/questions/comments/requests.

Installing if you're running the Stock ROM
I highly recommend backing up your apps and data with Titanium Backup beforehand as you'll need to do a factory reset to install. A Nandroid backup in ClockworkMod recovery would be a good idea too, if you want an easy way to get back to stock.
- Make sure you have your bootloader unlocked and you have ClockworkMod recovery installed.
- Download the ROM install zip from the above link and place either on your Internal SD Card or External SD Card.
- Reboot into ClockworkMod recovery (either with 'adb reboot recovery' or by powering on and tapping Vol+ immediately)
- In CWM, perform a 'wipe data/factory reset'
- In CWM, choose 'install zip from sdcard'
- Choose either 'choose zip from sdcard' or 'choose zip from external sd card' depending on where you placed the ROM zip.
- Navigate to where you placed the zip file and select it. Choose 'Yes' when asked to confirm install.
- When the install is finished, go back to CWM's main menu and choose 'reboot system now'.
- The first boot up may take longer than usual, up to a few minutes... this is normal.
- Go through the initial setup.
- If you backup up your apps with Titanium Backup, grap Titanium Backup from the Play Store.
- Restore your user apps and data with Titanium Backup (you can also restore data-only for IdeaDesktop, this will restore your desktop to the way you had it before), then reboot once more.
- After it finishes rebooting, open Titanium Backup again... if it complains about the Android ID changing, choose to restore it (this may cause another reboot).
- Enjoy!
