I just installed Cyanogenmod on my Samsung Galaxy S2. I want to install Google Services app ZIP. For that I have to reboot the phone in recovery mode. But it is only showing
Downloading... Do not turn off target!
What should be done?
You have rebooted to Download Mode by mistake. You needed to reboot to recovery mode. To do that, follow these steps:
That's it. I think you have a custom recovery installed and can find your way about it.
So you don't have a custom recovery installed and have the stock recovery. I have no idea how you installed Cyanogenmod without a custom recovery (so please include the process of how you did it in your question), maybe through ODIN? If so, flashing a custom recovery like CWM or TWRP is similar in process to the way you flashed CWM/TWRP. I'll point you to a guide on how to do this here.
