Hi all. i have rooted my Asus Transformer Pad TF102CX and using TitaniumBackup Pro uinstalled some system apps, and now it freezes on asus logo. Charging working, Using VOL+ and Power Button i can acess to DROIDBOOT, here i have fastboot acess, and
i can reboot to recovery. I trayed ADB Sideload in Recovery, i am used stock firmware from Asus page, but it says: Signature Verification failed. Can anyone create backup from system in *.img format? I want to try use fastboot to flash system.
