Stuck in Lenovo Recovery, no boot
Please excuse the basic grasp I have of Android and updating software. (A little knowledge is a dangerous thing in my case!)
I stupidly removed some pre-installed apps to try to prevent various malware from my A850+. I now cannot boot up into homescreen. I tried installing an update package I found, using the Lenovo updater, but it got no further than 50% then failed. However, somehow the phone booted to allow me to install some apps from the pulldown menu. I very nearly managed to install CWM but after getting this and the firmware update onto the SD card I can't reboot - it's stuck on the Lenovo screen.
Any tips about how to complete this?
