Help I bricked my phone

[Oguz Kaan]

Phone :asus zenfone 3 ze552kl

I unlocked the bootloader, then installed TWRP Recovery 3.2.1 ZE552KL, then the twrp screen opened without any problems. After that, I finally installed the magisk 25.0 zip file I downloaded from the install section in TWRP and pressed restart. TWRP told me something about installing TWRP versions and I confirmed it. Then the phone started to turn on and off infinitely. I keep seeing the bootloader unlocked warning screen and after 3 seconds the phone turns off, turns back on, turns off, turns back on. When I click the enter the recovery mode button, the phone turns off and on again and I cannot enter the recovery mode in any way. There is nothing I can enter except the FASTBOOT screen. I don't care if my data is gone. Please someone with knowledge help me

not familiar with your phone. the very first thing you should have done is make a nandroid backup. but that is not an option at this point.

not sure on your phone, but in fastboot mode what options are listed? is recovery one of them?

do you have adb setup on your computer?

Most likely you tried to install a file that was corrupt or for a different model of phone. The phone is bootlooping because its system software is damaged and it cannot boot.

I don't know ASUS devices, but you should be able reflash the phone from fastboot mode (it will require a computer and fastboot drivers, but you've probably got that already if you unlocked and flashed TWRP). I'd guess there will be instructions somewhere in the XDA Zenfone 3 forums, either in the guides or the ROMs subforum. I'd probably recommend finding a stock firmware package and reflashing all the way back to official software, then trying to work out what went wrong.

Hi!
Boot the phone into Fastboot mode and connect the phone to your computer and run the following command: fastboot erase cache. Then, run the command: fastboot flash recovery twrp.img (replace "twrp.img" with the name of your TWRP recovery image file). Then run the command fastboot reboot to restart your phone. Try booting into TWRP recovery mode again and use the "Wipe" option to wipe the cache and data partitions. And finally, try installing the Magisk ZIP file again using TWRP.
You are welcome
