Today I unlocked my phone's (Xperia L) bootloader and installed CyanogenMod 11 on it. After I did it, I tried to install WhatsApp, but it couldn't restore my messages. This is what it said after installing WhatsApp and putting my number:
Sorry, couldn't restore messages(not exactly like that, but in Portuguese)
How can I restore my messages? If not possible, just recovering my account would be fine...
