I have a similar problem with Huawei Y320-U030, MTK 6572, Android 4.2.2 with many malware infections. Almost all applications keep crashing, Factory Reset from Settings does not work, but I can do it from the recovery and it seems to complete successfully but when the devices boots, all user applications and files are there. I have flashed it with stock ROM and backup ROM from an other working similar phone, the flashing process completed successfully but when the device boots all user files and applications are untouched, even after formatting the whole flash with Sp flashtool, Volcano box and Miracle box! An applications called DU Speed Booster is set as device administrator with a pattern lock which cannot be deactivated. Uninstalling the imo application makes the device reboot and hang on Huawei logo untill the battery is pulled out. I can't install any new apk or root the device even using PC. Music, videos, and photos in the internal memory can be copied with a computer but cannot be deleted. Formatting the internal memory with a PC seems successful but all files on the device are intact. Very interesting case indeed.
