I could get it to work with Odin.. I plugged the USB with the phone and ODIN showed yellow thing on it with port working... But I Cant get it in download mode
please help me!
Here are some questions so that we might be able to help you:
-What exact model do you have? 5660 or 5660M (Bell Canada variant)?
-What exactly did you try to flash?
-To get your phone in download mode, did you try the "three button combo"? meaning: volume down, home and power all at the same time.
-Are you sure that whatever you're going to try and flash this time is going to be suitable for your phone?
Good luck,

*EDIT* - If you cannot get your phone into download mode at all, I suggest buying a USB Jig (I bought one while back, never had to use it) it's only a couple dollars and should force your phone into download mode.
From there:
If you haven't already solved your problem, download odin (if you don't already have), and try restoring the stock rom, or a rooted stock rom. This will most likely un-brick your phone, as it would seem is what you did. Once ODIN is downloaded, you're going to want to plug your phone in to your computer via USB, launch odin, and then install the Rom by placing it in the PDA section, and then pressing Go, initiate, or whateve the button is. This should fix your phone so that you can go back into recovery mode once you're done.

After installing the Firmware I got a newer problem namely Use Emergency Recovery Function blah blah "+ Reeboting every 5 seconds ... the problem is there I can't access Downloading Mode because it's always Reebot every 5 seconds. I tried going to the Samsung Service Center, and he said "You have to replace the mainboard to be able to turn on your Smartphone" what does that mean? Do I have to replace the Mainboard?The Price of Maiboard very expensive..
I don't know what to do ... is there a solution to solve this problem? Please

[help] oppo f9 boot loop

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?
@sd_shadow
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.
