I have rooted my phone earlier with KingoApp and then later changed the boot animation and shutdown animation with Root Browser after rebooting, it only shows the unit's logo and shows white screen for a while and then turn off. I don't think it's a bootloop, I also tried the recovery also but nothing seemed to help. Please can someone help me? My phone is Cherry Mobile Flare J1
You most likely bricked it. If you have a custom recovery installed, (Hopefully you do) you can unbrick your phone by booting up into it and reinstalling the stock software. Can I ask what recovery (if any) you have?
If you have TWRP you can navigate to: Wipe > Advanced Wipe then wipe cache, dalvik cache, data, system. Then navigate to: install/flash then navigate to where your ROM is and flash it.
