- Model Name: Zenfone 4 ZE554KL
- Firmware Version: None
- Rooted or not: Not rooted
Device info:
Yesterday my zenfone 4 stops working and can't boot (always looping) on asus logo so I'm trying to reinstall Android on my device but I can't unlock bootloader.
I've tried shakalaca from XDA-Developers method but not works:
Trying to flash with TWRP:
On asus website I can find a unlock app but my device does not start to make installation of this apk and recovery mode (power + button low volume) does not starts too. The only access I have is fastboot mode (power + button high volume). Someone can help me ? Tks!
