No i have tecno w4 3g model also dead like yours,except i have led light when i connect to charger and also it's detected by pc except the error 4032 that am tired of,i can't recall my build number,so it's a trial and error for me,it has more than one rom and that's hectic,am struggling like you with the error 4032
Update to this post. I created a full backup of the rom from another phone of the same build and used it to flash the phone. It worked perfectly afterwards. Thanks for the help.
