I just installed it on my P710. Installation went flawlessly with CWM Recovery. Sadly, you definitely feel that there are still many bugs, e.g. some menu points in the Settings don't work and crash (for example "My Settings"). Also, the front button illumination doesn't work which is kinda confusing but you get used to it.
I also had the problem that I couldn't download anything from Play Store because of the error RPC:S-3. If you have this error, follow these steps, they worked for me:
- Go into Settings.
- Go into Accounts & Sync.
- Go to Accounts, then Google and click on your account.
- Press the menu button.
- "Remove account"
- Add the account again manually.
Then it should work again!
Other than these tiny things, it's great and way smoother than the Stock. Hopefully this will push some more advanced developers than me more into Optimus L7 II development.
