Hold the volume up AND down button down along with the power button till the vibrant screen flashes once. the let go of the power button but keep holding the volume up AND down button untill it goes to the download screen

I just spent the afternoon recovering my phone after the OTA update.
I was able to get into download mode using the following:
With the phone powered off hold BOTH volume keys while simultaneously plugging the USB cable(that is already attached to your pc) into the phone.
Worked every time for me. Hope this helps.

Hi I have tried that and other buttons combination for the past 30 mins and found nothing. I have read into that any vibrant from the batch in august have been disabled for the download mode, is this true?

Pull the battery out first.
plug in usb
hold up, down and power buttons
reinsert battery with free hand.

That's how it works for me.
If I hold the power button while doing the above I only go into recovery mode.

i'm starting to get worry because i tried everything and nothing is happening. it is as if my phone has disable the recovery mode.

The volume up/down button thing never worked for me either. For me, the only thing that works is adb (the android debug bridge). Download/install the samsung drivers, and the android SDK (see messages on this board for links & instructions).
On the phone go to Settings -> Applications -> Development and check the USB Debugging box. Connect your phone to your computer via the USB cable, open a command prompt & type 'adb devices' w/out the quotes. You should get one listed device if you've done the above correctly. Then type 'adb reboot download' to put your phone into download mode.

[GUIDE] Entering ADB/Fastboot/APX mode instructions

I wrote this awhile back to provide known methods to enter each of these modes. I know it's rather wordy, but may help those that are newer to all this. See the link below for a more concise write-up. I'll try to keep this updated with any corrections and/or new methods and feedback is very welcome.
How To Enter APX, Fastboot Mode and Recovery menu​
Special thanks goes out to tobdaryl for providing the foundation for this guide and to daws for
providing a previously unknown method (USB cable plug in while tablet is turned off).​
Pertinent links:
The methods below written more concisely by tobdaryl: How to enter APX mode or Bootloader-recovery menu
Universal Naked Drivers (for APX/ADB/Fastboot modes): [ADB/FB/APX Driver] Universal Naked Driver 0.72
To install the SDK tools & drivers in Windows 7 (and other versions?): [HOWTO] Install Google SDK and ADB drivers...
The following instructions are written on how to enter APX mode. To enter Fastboot and Recovery modes, simply follow the same instructions but use the Volume Down button. Once the message: "Checking for RCK.. press key <Vol_Up> in 5 sec to enter RCK" is displayed, follow the displayed instructions to enter the desired mode. Note: The screen remains blank in APX mode.
When your tablet is turned off, to enter APX mode:
Make sure your USB cable is connected to your tablet and PC. While pressing the Volume Up button, press the Power button for a few seconds, and then release both buttons.
Make sure the USB cable is not plugged into your tablet (but is connected to your PC). While pressing the Volume Up button, plug the USB cable into your tablet. Release the Volume Up button after a few seconds (modified from daws' suggested method).
When your tablet is up and running, to enter APX mode:
Turn your tablet off and wait a few seconds. Connect your USB cable to your tablet and PC. While pressing the Volume Up button, press the Power button for a few seconds, and then release both buttons.
Make sure your USB cable is connected to your tablet and PC. Open a command prompt on your PC, navigate to the folder containing adb.exe, type: adb reboot and hit the Enter key while holding down the Volume Up button until the screen remains blank for a few seconds.
From a tablet based terminal emulator, type: su and hit the Enter key, then type: reboot and hit the Enter key while holding down the Volume Up button until the screen remains blank for a few seconds. One suggested app (by tobdaryl) is the free Android Terminal Emulator from Google Play. Note: You must be rooted for this to work.
Press the tablet reset with a paperclip while pressing the Volume Up button until the screen remains blank for a few seconds (the reset is located about either 25mm or 1" below the sdcard slot). Note: Do not press hard!
When your tablet is in Fastboot mode, to enter APX mode:
While pressing the Volume Up button, press the Power button for 10 seconds. Release both buttons a few seconds after the screen goes blank. One variation is to wait and press the Volume Up button immediately after the screen goes blank and then release it after a few seconds. If you wait too long to press the Volume Up button, your tablet will just boot up normally.
Make sure your tablet has the USB cable connected to your PC. Open a command prompt on your PC, navigate to the folder containing fastboot.exe, type: fastboot -i 0x0B05 reboot and hit the Enter key while holding down the Volume Up button until the screen remains blank for a few seconds. One variation is to wait and press the Volume Up button immediately after the screen goes blank and then release it after a few seconds. If you wait too long to press the Volume Up button, your tablet will just boot up normally. Note: Newer versions of fastboot.exe do not require the "-i 0x0B05" option.
Or, as a last resort!
Remove your tablet's cover, disconnect the battery, press and hold the volume up button, and reconnect the battery!
The following instructions are written on how to switch from one mode to another (not covered above).
When your tablet is up and running, to enter Fastboot or Recovery mode:
Make sure your USB cable is connected to your tablet and PC. Open a command prompt on your PC, navigate to the folder containing adb.exe, type: adb reboot-bootloader and hit the Enter key. Once the message: "Checking for RCK.. press key <Vol_Up> in 5 sec to enter RCK" is displayed, follow the displayed instructions to enter the desired mode. Note: I was unable to verify this method possibly due to having the AndroidRoot.mobi custom bootloader. This method only performs a regular reboot for me.

Note: Newer versions of fastboot.exe do not require the "-i 0x0B05" option, Note2: I was unable to verify this method possibly due to having the AndroidRoot.mobi custom bootloader. This method only performs a regular reboot for me.
When your tablet is in Recovery mode (TWRP v2.3.x), to enter Fastboot mode:
Select the "Reboot" option and then select the "System" option while pressing the Volume Down button until the screen remains blank for a few seconds. Once the message: "Checking for RCK.. press key <Vol_Up> in 5 sec to enter RCK" is displayed, wait 5 seconds for the icons to appear, and follow the instructions to select/confirm fastboot mode. One variation is to wait and press the Volume Down button immediately after the screen goes blank and then release it after a few seconds. If you wait too long to press the Volume Down button, your tablet will just boot up normally.
When your tablet is in Recovery mode (TWRP v2.3.x), to enter APX mode:

Nice guide! Thanks for taking the time to gather the information and create this guide.
It is clear, detailed, and easy to follow.
It should be a stickied.

Hi I tried connecting my device to my computer after holding down the buttons to get into APX mode. And after about 5 seconds I heard a connection sound then Windows told me the USB device malfuntioned. Any idea why?? I'm trying to fixed my friend's soft bricked tablet which cannot get into fastboot mode.

A couple of quick thoughts if it's not the device itself: check to make sure the cable is good, try a different USB port, and try re-installing the drivers (using the Universal Naked drivers, specifically the APX one included in the package). I've had troubles on one pc where it would connect and disconnect - it was either the USB port acting flaky or the OEM cable I was using...
Watching Windows device manager, is it showing it as an APX device or something else before it disconnects? Also, what kind of error?
Hopefully some others may have added suggestions...good luck!

No problem at all and glad to hear it wasn't a complicated fix! With APX and other modes, do have the two methods. Holding both buttons at same time, but I do find somehow it doesn't always recognize them (maybe I'm not holding the volume button solidly?). As worked for you, the other option is to have it powered off, hold the volume button, and then plugging it in to get it to power on and go into APX mode (remembering it's just a black screen but can tell by checking Windows device manager - mostly mentioned for any others that may come across this!).
If have more questions on the rest of the restore process, might be good to start a fresh post for the remaining steps. Good luck with getting it back up and going!

Axon 7 stuck at boot screen, cannot shutdown and restart.

Hi. Previously I flashed latest TWRP on my B03 Oreo in attempt to root my device but seems like TWRP not mount the internal memory. So I found this thread https://forum.xda-developers.com/android/general/how-to-fix-unable-to-mount-data-t3830897 and followed it but then I stucked at "Your device software can't be checked for corruption. Please lock the bootloader." screen.
I also cannot force shutdown the phone, pressing multiple combinations of power button and volume buttons also doesn't effect the phone at all. Now, i am waiting for the phone's battery to drain until zero. Maybe anyone can help me? If I can boot into EDL, I can reflash back the firmware of my phone and maybe that will solve the problem.

I follow that thread because my TWRP do not mount the internal sd card in the recovery mode.
I actually used Nfound version of TWRP but it never boot to recovery mode at all.
I cannot press anything at the screen right now. The screen seems to stuck. Is there anything I can do via wire to pc other than adb since adb cannot detect that screen as either edl or fastboot or adb mode.

I have a similar problem. My Axon 7 stuck in EDL mode, but no software can connect via USB. No button works, screen is of, no LED. Only sign of life is the 9008 com device in device manager, when I connect it with USB.
I've put it into the freezer right now, to wait until the battery drains. But I think it will take a while, because it was nearly full and the screen is off and not much energy is used for EDL mode.
Any other ideas guys?

Solution: Got it back to life by draining the battery in the freezer.

I am in the same position, but with no OS and now cannot get to TWRP. Toolkit and MiFlash do not see the device.
Heading for the freezer.

if they don't see the device, then you are not stuck in EDL...?
How do you see the phone in the device manager? Or do you see it at all?
Otherwise you're putting it in the freezer for pretty much nothing, as it'll still not be recognized after you charge it again. you might damage the battery (reduce its capacity).

I had been flashing bootstackers and matching roms to no avail. Error 08 on TWRP twrp-3.2.3-0-ailsa_ii .
Now, after letting it just sit for a day (?battery discharged), it won't boot into even the warning screen and definitely no recovery.
Disconnected from the PC, Power button gives a brief red led flash. Power held gives a 3 sec red led. Power + Vol + and - in various combos , just the 3 sec led.
Attaching to the PC gives this white screen, which goes off after a couple of seconds. Power button brings it back on, and it stays on, until I disconnect from the PC. Holding power for 15 secs while connected turns the screen off, and pushing power again turns it back on, or sometimes it comes back spontaneously with a few lines across the screen.
Power & Vol +/- combos just bring back the white screen with a few more lines...
It does not show up in device manager, but momentarily is seen by Axon toolkit as an ADB!
Thanks for any guidance you can give.

You can just attach screenshots to xda, i can see them that way too.
I really want to see this white screen, that sounds very weird. If you can get it to be recognized as Qualcomm HS-USB QDLoader 9008 then you're going to be able to flash whatever from EDL Tool.
So this means you CAN enter TWRP? If you are in TWRP then your phone is just saved, because you just need to know what to flash...

Now that I checked my response wasn't even sent lol. Good that you could fix it on your own. Just a heads up, you should use EDL Tool (or standalone MiFlash) instead of axon7toolkit, axon7toolkit is outdated and finicky already.

[GUIDE] Booting your OnePlus X with a broken power button

Got a broken power button and need to turn on your OnePlus X?
As long as one of your volume buttons and your microUSB port still work, you're lucky.
If the volume down button is working:
1. Press and hold the volume down button.
2. Connect to a USB power source.
3. The phone should vibrate and boot into the recovery. You can release the volume button at that point.
4. If you have the stock OnePlus recovery installed just tap "English", "Exit" (if present), then "Reboot".
5. Your phone should now boot up!
If only the volume up button is working, things get a bit tricky.
Before you start, read through all of the steps and the paragraph below to make sure this goes as smooth as possible.
1. Connect your device to a USB power source without pressing any button.
2. Wait for about half a second, then press and hold the volume up button.
3. If you've hit the right moment, your device will boot to fastboot mode.
4. Connect to a PC and run the command "fastboot reboot".
(If you don't know what fastboot is or you haven't set it up yet you should be able to find plenty of guides online.)
A word of caution on finding the right moment to hit the volume button:
Start with longer delays and work from there. If you hit the volume up button too early the phone will enter EDL mode, which can be hard or annoying to get out of. EDL is Qualcomm's low-level Emergency Download Mode which allows flashing the device.
When entering EDL mode the phone won't vibrate and the screen will stay off. The phone remains in EDL mode after disconnecting the USB plug.
Normally you could press and hold the power button until a hard reset to get out of there, but in this case you have the following options:
- Unplug the battery to power down the device completely if your device happens to be open.
- Wait? For as long as it takes for your device to reset from this mode on its own or for the battery to run out. idk, good luck.
- Use an EDL mode flashing tool on a PC to send the power reset command to your device. This could be viable if you have already used such a tool before, e.g. by following the "Mega UnBrick Guide" by Naman Bhalla. Alternatively you could dive into this cross platform command-line tool, which works on WIndows, Linux and macOS. Using this approach is a bit overkill and quite the tangent from what you're actually trying to do, but being able to make use of EDL can come in handy in other situations as well when you're tinkering with your Android device so taking that detour might just be worth the time.

Awesome, it worked for me.
-Incase you have entered into EDL mode, then continue charging your mobile, it will be back to old state after sometime (12 hours maybe).
- To get fastboot mode, first insert power cable then wait for vibration/ screen light illumination after that press volume up button. if you press volume up button before inserting power cable, then it will go to EDL mode, so be careful about it.

Can't unlock bootloader

Hi,
I have trouble unlocking my A40. It's 2nd piece I own and the problem is the same.
When I follow the steps from this forum;
Go to Developer Settings and enable "OEM Unlock" option
Power off the device and boot in download mode
In download mode, you will see the long press and volume up option to unlock the bootloader
Unlock the bootloader. That will wipe your device so be sure you made a backup of your data
After bootloader unlock, boot up the phone and make sure it is connected to the internet or it will trigger rmm prenormal
Setup the phone without google account and others
Reboot in download mode and flash the recovery and vbmeta images
Boot to TWRP
Format data in TWRP
Flash the Multidisabler zip
Now you can reboot

I'm stuck at the 3rd point.
I don't see ANY instruction about Volume UP + Power in download mode. Nor FASTBOOT see my device to run actions with it.
What I see is only "Volume down key + power key for more than 7 secs Cancel (restart phone).
And holding Vol UP + Power doesn't do anything.
How to make this work?
Thanks.

You did enable OEM Unlock, correct?
Turn the device completely off, without any cables connected. Keep a USB cable ready that's plugged into your PC.
With the device powered off, hold both Volume buttons, and plug in the USB cable connected to your PC. Do not press Power. You should see a prompt on either a green or blue screen; select the option for Device Unlock Mode.

Finally.
Thank you for making me try for another time
