[help] oppo f9 boot loop - Android Q&A, Help & Troubleshooting

Hello guys, I got my OPPO F9 in boot loop and I am unable to turn it off.
It keeps restarting itself till battery drains out. When it tries to restart, I try to put it in to "FASTBOOT" but that won't work and keeps restarting.
Recovery mode won't work too.
Uploaded a video but am unable to put the link because I am new as a member here.
Can you please help me?

same problem here
hi there, i have the same problem with you, do you find the solution now? can you please share with me? tq

How does it happens? What you have done?

Diagnosis
I have the same problem, stuck in bootloop, cant boot to recovery mode. I brought mine to the local oppo service centre and they tried to flash it. But it did not work. They said that the motherboard is broken and have to be replaced by a new one(costs 1/3 of the price of the phone in my country). They said the cause maybe from a third party applications or may have overheated.

I am not expert in MediaTek based phones and Indian Companies phones.
Flash your phone's firmware again. Get firmwares from this thread.

Try flashing above firmware, it may recover your phone.
Press Thanks if helped.
I cant get into fastboot mode or adb mode because the key combination also doesnt works.
Also because of restarting the phone doesnt get detected in PC . Is there any other way ?
