I want to see how the things develops for this phoneNote that it's untested.
You can download it here, from my MEGA acc. The link should work for quite a while:
Here is the original 355 thread with the download from Baidu: https://club.lenovo.cn/detail/5432739
Also, I'm quite curious why you are supporting this phone when you don't have it.
I think that if some developers start to porting rom for this phone it will be a best buy!
