Due to wrong custom rom, my phone is not booting. How can I fix this?

[AC Question]

due to wrong custom rom, my phone is not booting.

I have tried to install a wrong custom ROM in my Huawei Honor Holly U19 smartphone. And after that it is not booting in any ways. I have tried to resolve it according to costumer care representative of Huawei (that download holly update.zip file, put it in sd card in a folder named "dload" and press vol+,vol-, and power button simultaneously.) but it not work. I have corrupted my phone internal memory in this way(perhaps). I have also tried SP_Flash_tool but it shows BROM ERROR:S_FT_DA_NO_RESPONSE(4001) DA didn't send response data to Flash Tool! How to fix this problem? Please help me!

Hi and welcome to Android central.

My best suggestions is to start from scratch again. Have you used ADB before? I would investigate this. The Most Useful Things You Can Do with ADB and Fastboot on Android

Find the original image for you phone. Huawei Honor Holly [Hol-U19] || All-in-One |… | Android Development and Hacking | XDA Forums

Use ADB to push the image to the phone and also install it. The other option is to root the device and install a new recovery and a custom OS.

Goodluck
