Hello everybody.I am using Acer iconia b1-721(rooted).I have installed an app called softkeyz (an app to customize softkeys).yesterday i saw that there is Android L softkey pack is available and installed it.Device rebooted as usual but after reboot,my softkeys and notification bar is not at their place : they are deactived or something like that.so i rebooted,unrooted the device,hard reseted several times but no change.I have not installed any custom ROMs or CWM i was using stock android 4.2.2 that came with device.i am trying to flash custom ROMs now.I think may be it will solve that problem but i can't find any ROM for Acer Iconia B1-721.Please help me
