I've been trying to fix this phone for about a week now with hardly any luck.
Problem: When pressing the power button to turn phone on, there is no samsung boot logo. the only thing that shows up is a black screen, [the backlight] it will stay that way until the battery dies.
i know it's not a problem with the display because i can get to the recovery screen by pressing the three buttons. i tried numerous wipes and factory resets, even tried to reboot from there. but it still wont boot up, it only ends up with that black screen. Also the green battery shows which further indicates that it's not a display problem.
FCC ID: A3LGTi9500
MADE IN KOREA BY SAMSUNG
That's basically all i know about this phone, not sure what mtk version it is either, i know it's a clone because on the hardware differences under the hood compared to the real S4. also it shows mt65xx [i installed the driver for it btw] when connected at battery screen.
[it's probably a legend or a superking since it's from korea i think]
Some things i've tried: i downloaded android SDK, MTK droid tools, SP FLash tools, for some reason, i keep getting error 8200 in sp flash tools and mtk droid tools doesn't detect my phone.
I tried flash updating firmware with adb sideload, it always ends up with an error ''aborted''. i can't enable usb debugging since the phone wont turn on.. :/,
Also can i make it work with a stock recovery img. or something?
Attached: battery screen, recovery screen, when the phone is powered on, after battery pull.
Can anyone help me?
