I have a HCL Me u1 device that is running the 4.0.3 version of Android. I want to upgrade it to the latest version of Android.
I don't have an SD card. Are there any tricks for upgrading without one? How do I root the device and backup my old files?
I rooted my device with superuser, now I want to know how to upgrade to the latest version of Android. I downloaded the Zip from online but I don't know how it works.
