How to enter fastboot mode on Oppo A39? - Android Q&A, Help & Troubleshooting

I've tried to press and hold Power Button + Volume Up, but it doesn't work.
adb reboot bootloader from adb & fastboot also doesn't work, it reset the phone then back to home screen.

Uh, another A39/CPH1605 user here. I think you're trying to root this device. You basically can't reboot your phone into it, without TWRP.

you can use rom manager which directs you to recovery mode without pressing vol buttons
you can use xposed modules which provide three reboot option

ahhh ... but the proplem is that there is pattern lock which i forgot saw i can't do this one
So your phone is pattern locked and you want to get to recovery, do it via adb. Make sure you have adb drivers installed, look here for an easy way to setup adb.
In command prompt, type the following:
Code:
adb devices
adb reboot recovery

in rom manager there is direct option enter into recovery
if you press yes then it will direct enters into recovery mode without any button press

So, if u can tell me what to do !

Lg optimus ls970 fastboot no power button

basucally flashed a rom and it went bad and my phone wont boot, i can only get it into fastboot but plugging it in and holding volume up and i have no power button, so i cant select boot into recovery, is there any way i can through the cmd?
*edit*
I figured out how to boot to recovery, download a recovery img, and in fastboot cmd you go
Fastboot flash recovery_image_name.IMG
Then
Fastboot boot recovery_image_name.IMG

Depends on which version of the official software/firmware you had installed. You might check out this:

If you were on a KK set up then that recovery won't work.

all i want to know is, when im in fastboot is there some kind of command line or any other way i can select recovery mode besides the power button? my power button is broken, and i cant turn on my phone to reboot into recovery due to me soft bricking it.

So when you turn it off, leave it set there for a bit (guess you would have to let it die at this point...), and hold Volume Up and plug in the USB cable to the PC - you don't get into Download Mode? But as far as booting to recovery without the power button and not able to boot into the OS...I can't think of a way. There are no fastboot commands to get to recovery and without it booting to anything but fastboot, there is no way to utilize adb commands either.

Phone doesnt respond on boot screen

Brand new phone. Didn't root yet. I tried to encrypt my phone, did the process.
Then my phone doesnt respond.
It just said "miui doesnt respond"
I really need help with this.
Thank you in advance.

Sprint G5 will not boot into bootloader mode, help!

I can boot into recovery, but when I select "reboot to bootloader" it just reboots as normal. Same for when I try "adb reboot bootloader." It just does a regular reboot.
Any help?
Have you made any changes to your device from stock?

It may be a Sprint thing. I get the same exact results

How about 'adb reboot edl"?

Somehow I Can't get to EDL mode

I just officialy unlocked my bootloader because I Can't enter EDL mode somehow. Tried everything, EDL scripts, adb, holding the volume buttons...
The phone always restart the the system (it works fine). This is weird because I can't do factory reset either, it always boots back into my system.
Can somebody help me in this?
If you have an unlocked bootloader, why do you need to go to EDL mode instead just use fastboot.
Care to explain better?
The issue is: I flashed TWRP with fastboot. When I try to boot into it (Holding Volume up + power) i just get back into system.
This is just weird, as I can't do a Factory Reset either!
Download edl7.zip file from xda thread and go into fastboot mode and double tap on cmd file...your device will go in edl mode (red led blink)

EDL is for flashing fastboot files for locked bootloader as flashing through fastboot doesn't work. If your bootloader is unlocked you can just use fastboot. For TWRP are you getting any error while flashing it, if not you should boot into TWRP by holding volume down and power button with your phone turned off.

Hey man. Thank you for your help. But I think that I'm not being clear on what my issue is. I have some experience on flashing twrp and rooting. But never faced something like this before.
I can't even do a factory reset (from the settings menu) as the phone restarts and just goes back to the system. I flashed twrp but when I try to boot into it I get back to the system. I try to reboot into bootloader via the update menu and the phone resets and just get back to system.
It's just as if I can't acess the bootloader menu at all.
That never happened, try holding volume button before pressing power button. You can also try it through adb, make sure you have usb debugging turned on. For fastboot use adb reboot bootloader and for recovery adb reboot recovery

Yeah, tried that too. This is just way too weird to be normal. I'm sure that I did everything right.
