Xperia Z C6602. Unrooted. Locked Bootloader.
I recently downgraded my phone from Lollipop to Kitkat 4.4.4. Cuz i had no knowledge about the process of downgrading, i spared the 'wipe data' option in hope to access my data again. But unfortunately, my phone is stuck in boot loop and the data kept in it is VERY VERY important! I tried several firmwares of jb,kt,lp to flash it with flashtool but no luck. If i could just access my data somehow only then will i be willing to select the 'wipe data' option. Any kind of help will be appreciated. Can't i transfer my data via adb while my phone is switched off? Or any other workaround?
P.S: When i flash kitkat rom, my phone gets stuck on 'NFC Firmware Update'.
