My samsung g advance i9070p which is rooted but still running stock Rom XXLPE,is not going beyond the Samsung logo and sound. I suspect this happened after i did some kernel tweaks in the ROM toolbox application i had downloaded from Google play and rebooted. I have tried all options in the bootloader like rebooting, wiping data/factory reset, trying updating from sd storage (I haveTitanium backup of the stock ROM but it shows empty but a CWM xxlpe ROM i had downloaded from XDA can be read but when i try to install it says its unsigned). The computer now does not recognize the phone as the MTP is not installing so download mode will not work. Help me out guys
