Cannot unbrick [cannot enter EDL mode] - OnePlus 8 Pro Questions & Answers

Hoping someone can shed some light. Rushing to root phone again to send back warranty replacement, in my haste my laptop died mid flash and now can only boot in Fastboot and Crashdump Mode.
I am attempting to restore to factory via the MSM tool but cannot for the life of me enter EDL mode.
With phone powered off and pressing the vol up and down keys while plugging into the PC, it only enters Fastboot mode
I have tried to do it with phone off, rebooting from Crashdump mode, from fastboot and it seems that no combination allows me to do so.
I have also tried just vol up and vol down. App loaded at the flash screen, not loaded, etc.
Thanks in advance

What I did when I was in Crash Dump Mode was,
Press and Hold Power Off and Volume Up button and release when the screen goes off. Now your phone is switched off. Now to enter the EDL mode you need to press and hold volume up and volume down buttons at the same time...and then connect the mobile to pc while still holding the buttons. Done. MSM tool will detect your phone.
NOTE : Also keep the Device Manager window open on the PC while u connect the phone to pc and check if it shows up there.

It always seems to take me several tries to get it right. I think if I don't hit the vol +/- keys right at the exact time that's the problem. Just be patient and keep trying. The first time I did it, it took me what seemed forever. Thought maybe my phone was broken.

I have been doing custom roms since the old win ce devices....and yet you sir have been able to make me feel like an idiot haha. Thanks for this. you had it spot on!! thanks so much

Hello Folks. So i have found myself in this situation as well. MY phone wont go off and keeps restarting to CrashDump Mode. As such can't seem to get into EDL mode inorder to flash. Any tips? I have tried all the above methods nothing seems to work. Is there a different key combination or a fastboot command i can use to achieve EDL? Help a brother i'm going nuts. Device IN2020

You just need to keep trying it. Make sure you hit vol+/- at the same time and hold for a few seconds, plug in the USB cable, then let off the vol keys. It's difficult to do and get right with two hands. Recently did it again as I wanted to upgrade to the 11 beta from a clean system. Seems like it took me forever to get it this time but eventually I did.

Use usb 2.0 port.

After using 2.0 instead of 3.0 and the phone connected stable for a while (after many tries)
able to finish the msm operation successful ..
But phone not booting .. getting black screen after 1+ logo
at this point I thought to clear cache but My phone is locked I cannot use any recovery .. I cannot even go into oneplu recovery LOL .. It seems like I am doomed

For me personally I could only get it to work on USB2.0 ports. On USB3.0 it just puts me back into fastboot mode or when it does go into EDL MSM tool just fails with a communication error immediately.
I kinda bricked mine as well messing around with GSI ROM's and flashing too hastily and to the wrong partition lol.

It has always worked for me with USB 2.0 port and non oneplus cable.
originable cable would not work for me on usb 3 or USB 2 port, but 3rd party cable start immediately with USB 2 port.

I've had the issue where EDL mode works..... for a few seconds, then the phone reboots.
Very frustrating!
The MSM Download Tool does spot the phone, but since the phone seems to reboot, I don't have enough time to do anything!
Any ideas why this is happening?

You need to already hit start on msmtool BEFORE plugging in phone

1- start MSM tool (prepare the settings and choose the right oos)
2-keep the cable connected to one end (I prefere to keep it connected from the phone side first)
3-keep holding volume up/down for 3-4 sec and connect the other end of the cable to your PC
4-your device will be connected directly stop holding volume up/down and in msm tool press start wait for ≈300 sec
5-now your device should work as it was before

After rebooting my pc, and fiddling with drivers, I got it all sorted finally.
Thanks for your help, folks.

This is a royal pita! I remember when it used to be fun....
Anyway, I've been trying every trick in the book, and then some, but shiznit just isn't going right! The holding of the up and down buttons would be easier if this was the pixel, but it is a tad hard to not mistakenly hit the power button on the other side.
The device manager shows the Qualcomm QDLoader and the msm Downloader is showing the infamous waiting for device... I've been at it for 8 straight hours and if there was a local OnePlus store that sold the international version of the OP8P, that's where I would be heading in a few hours.... It's really frustrating to say the least.
Anyway, when I'm in the bootloader, the device manager shows the Android phone, so I'm thinking that maybe I am in the edl mode when the Qualcomm port shows up, but like I said, the msm is waiting....

tried everything and it is constantly booting into bootloader. I even tried an adjusted fastboot script to boot into EDL but it still boots into bootloader. I have booted into EDL before on a OnePlus 7T, and I have tried multiple times by pressing the OnePlus 8 pro volume buttons at the same time, but always bootloader. Just to check, I tried doing it on my OP 7T again and it worked perfectly fine. Help????

I have had to flash stock 4 times because I land in crash dump mode and it has always been a tricky situation to get into edl.
What worked for me 100% of the time was following the steps in the youtube guide below.
From 2:30 onwards
Hope it helps

I had the same issues, but fixed once read comments as per above. Let me summarize what I did:
1. installed driver Qualcomm HS-USB QDLoader 9008 (I'm using Windows 10) - driver in a cab file should be unpacked using command expand (with proper switches) to preserve folders.
2. launched MSM DT and had it configured and then pressed Verify\Start, as EDL is available only for very short time - 2-3 secs with screen turned off.
3. as my phone was stuck in booting loop I was just keeping presses Vol+/- waiting for EDL to be entered, MDM will find the phone and start uploading data.
Just don't give up trying.

Try different ports. My usb 3 port would force it into fastboot but usb 2 was fine.

What to do if the device doesn't have any usb 2.0 port?

Bricked Storm

Hello, I have a problem with my storm. Two days ago I received it and flashed the then latest cm13 and its corresponding recovery. Everything seemed to work just fine until yesterday when there appeared to be an ota update. After the download finished, the phone rebooted itself and is since then stuck with a black flickering screen. Every attempt to start the phone using recovery or bootloader seems to fail, as the phone keeps showing me the black flickering screen, no matter the combination of keys (vol+/vol-) I use to turn it on. If during the black screen I plug the phone to the computer adb can actually see the phone but says it's not authorized to perform any command. On the other hand fastboot won't even see the device.
Is there anything else I can try before sending it back to wileyfox?
Thank you in advance
I've made some progress, I found out that the device can be forced to Qualcomm HS-USB QDLoader 9008 mode by turning it off and then connecting it to usb while holding vol+ and vol-.
I've also found the stock firmware at https://cyngn.com/support.
Now it would be great if somebody could help me, and the others in my situation, to figure the wole QFIL unbricking out, because I'm overwhelmed, and can't seem to find the right info on google.
Thanks to anyone who'll care to help, or share some info
I had a similar issue so have created a thread with stock recovery instructions, which resolved the issue for me.

Thank you for your reply.
Unfortunately this does not seem to be applicable to my case because on my device fastboot mode doesn't seem to work.
I've spent an entire afternoon trying to get it to boot to fastboot mode using different vol keys combinations and timings, but none of them seemed to work. No matter the combination, it just kept booting to a black screen flickering.
I'm starting to think that it could be some problem unrelated to my actions because if, as I think it is, recovery mode and fastboot mode are two separated things, nothing I did would justify this kind of behaviour.

Sorry to hear you are still having trouble, it does sound like the same issue, was a CM13 update from the last couple of days, upon reboot I saw the wileyfox logo but when the Cyanogen logo would normally show during boot it displayed a black screen, which would flicker every few seconds. Holding vol- and power to reboot resulted in the same thing so I was unable use recovery.
When the display was black and connected via USB I was able to see the device using ADB but like you no commands were authorised.
Leaving the phone plugged in via USB and holding down vol+ and power until it rebooted I was able to enter fastboot, once the fastboot prompt was displayed on the screen I attempted using fastboot to boot from a custom recovery, unfortunately that just resulted in the same blank screen for me. I also tried booting the stock recovery with the same result, I admit I did not try many older CM recoveries, but I wanted to revert to CM12.1 anyway, as the accelerometer and gyroscope not working in CM13 at the moment is no good for me.
Only thing that worked was a stock restore, so I think something beyond the recovery got broken as you could not even boot a previously working recovery.
For the sake of sanity it may be work getting someone else try booting it into fastboot before resorting to Wileyfox support. Though your phone is really new so could claim a refund or replacement from the seller, that would probably be faster.
FYI if you do end up sending it to Wileyfox support they do flash it back to stock, I had a broken screen replaced, was repaired and back to me in just under 2 weeks.
What would be exactly the timing for it to boot to fastboot mode?
Because I just tried (again...) to plug it to the computer while powered off, then it powered on on its own.
After that I rebooted it by holding together power and vol+ and immediately after it rebooted (right after the vibration) I let the power button go and kept holding the vol+ until the black screen appeared again... no fastboot

Hi,
Just tried a few combinations to check timings for you.
Powered off, not plugged in, holding vol+ while plugging in phone end of usb connected to computer, keep holding vol+ -> boots straight to fastboot.
Powered on, already connected to computer via usb, holding vol+ and power, release power when vibrates to indicate reboot but keep holding vol+ -> boots straight to fastboot.
Are you seeing the black and white Wileyfox logo when first booting? When going to fastboot it should skip that. If you are not seeing the logo it might not show the fastboot screen either. You can try following the steps above and then issuing fastboot devices from a command/shell session to see if you are in fastboot mode.
I hope that is of some help.
Thank you but I can confirm that neither of these combinations work for me. When rebooted/powered the device shows the wileyfox's logo.
If I use your first method it just seems to freeze on the wileyfox's logo screen, and the computer won't even see it (it's not listed on the usb devices list) so fastboot's not an option.
If I use your second method, or any other I tried, it shows me the wileyfox's logo and then proceeds to the black screen, which can be seen just by adb (not fastboot) but I'm not authorized to perform any action like you described for your issue.
I'm out of ideas so I'm sending it back and getting it replaced. On the cyanogenmod irc they told me that to brick it like that it cannot be done just by accident but it should require a lot of deliberate effort, and that just installing cm13 + recovery doesn't justify this problem nor does an OTA update, so it's probably some other (hardware?) issue with a very bad timing.
I'm kind of sure it's not the vol+ button that's damaged, because if I leave the device powered off and then proceed to plug the USB while holding together vol+ and vol- it powers on, but the screen stays off meaning the Qualcomm HS-USB QDLoader 9008 mode has been triggered.
Anyway thank you for your help, I could rule out my inability to start the fastboot mode and blame it on the phone xD
Hope I'll be luckier with the next one...

No problem, I hope you have more luck with the replacement.
Here I am again, new device, still can't boot to fastboot mode (this time I didn't flash anything, just unlocked bootloader so it's not bricked).
"adb reboot-bootloader" works, advanced reboot menu works, yet the vol+ combination hangs on the vendor's logo.
I'm contacting cyanogen os people to try to understand what might be the issue...
Could you please confirm that your device boots into fastboot mode when using the vol+ way? thank you

Hello again,
So these 5 methods work for me, someone else may have other experiences:
Phone powered off, hold vol+ while connecting USB, other end of USB already plugged into PC, continue holding vol+ until booted to fastboot (almost instant).
Phone powered on, already connected to USB, other end of USB already plugged into PC, hold vol+ and power until reboot vibrate, continue holding vol+ until booted to fastboot (almost instant).
Phone powered on and in OS, already connected to USB, other end of USB already plugged into PC, debug enabled, from ADB console, adb reboot fastboot or adb reboot bootloader
Phone powered on and in OS, advanced reboot options turned on, hold power, select reboot, select bootloader, reboot
Phone powered on and in Recovery, select reboot to bootloader
Currently I am running stock everything.
Perhaps try different USB cables or ports, though I still get to fastboot without the USB cable plugged in.
My Storm was a pre-order so is one of the first releases, it is possible they have changed something since.
Edit: I have come across a thread on the Cyanogen forums which implies this may be related to encrypting your device: http://forum.cyanogenmod.org/topic/117661-bootloader-hangs/ - I see you have been there already
as reference mine is not encrypted at the moment

Hard brick [EU-axon mini 7] ?

Hi, I get this phone yesturday... I've installed last firemware ( 6.0 to 7.0.1 ) and after I tried with Tuliptool to install recovery but after this my phone dont show recovery when I tried so I was thinking I've forget to Unlock it before... and obvously I tried to unlock ( with tulip ) but I got error message in cmd ( I don't remerber... ) and now it show only Zte and it bootloop on it so I didn't have recovery, I can't use edl because I can't boot.. so there is something I can do or I bricked it in less than 1 day.. ? :S
Got the same problem
EDL can only be entered once the phone is completely off. You need to hold down volume up + volume down and then plug in the usb cable (dont touch the power button). The phone wont do anything, it will still look off but you will hear the device plugged in tone in Windows and will be able to find the device in zadiag. Also after a few attempts Windows stopped showing the device and I had to restart Windows before it worked again. Can you get this far?

no my phone is just showing ZTE when it is booting then just instant turns off and starts again showing ZTE and it is doing that until the battery is empty
I did have that before, I'm not sure the exact combination I used, charge it up and then remove the cable, hold the power button and either the volume up, or volume down or both for anywhere between 5 and 20 seconds before letting go and seeing if it stays off. If it doesn't work try again and again and again, Its completely trial and error and took me a while to get it to work

I'm not quite sure but on the European version of the Axon you can't do that by holding the buttons.
I understand that the only way to get in edl mode is software, no other choice than rebooting from the OS using the command adb reboot edl. So if you can't make your device completely started first, i guess it's bricked. But maybe i'm totally wrong.

I also messed up mine. I did everything until I had android 7, rooted, but lost IMEI. then I, THE IDIOT, tried to re-flash stcok android 6......booom. bricked.......
however.........power the phone off:
hold vol- power for 10 secs. phone should boot into FTM. then power it off by pressing power for about 5 secs. phone is off.
now vol+power and the phone should go to recovery, even if stuck on the logo, my pc reads it as recovery in adb devices......
tomorrow I'll see if I can get out from there. my experience doing this before is that from the recovery the ADB reboot edl works
cheers

Can't exit EDL mode !! OP6T

After unlocking my bootloader i just rebooted it to flash twrp. But it did'nt rebooted. While connecting to PC, it show
Qualcomm HS- USB QDLoader - 9008 (COM 8)
i can't reboot or exit edl
please help?
i also tried msm download.
but after 16s it showing "Sahara Communication error"
I had the same thing happen to me with the msm download tool connection. Try to hold down the power button and volume down or up for a good 30 seconds. One of those combinations worked for me to make the device boot. Just a suggestion. Hope it helps.

Power plus volume up till the phone shuts off then start over. Msm tool does this sometimes to me as well just restart it and the phone.
thanks everyone for their help. I tried the button combination too but it was'nt working.

I have also faced the same problem. I have tried all combination of keys to exit Edl mode without success.
The easiest way is disconnect the USB cable from PC/Laptop, connect the battery in case disconnected and connect to a power cable. Your mobile will start.

How long are you holding before giving up? You gotta hold that for a long time
Also make sure the phone is unplugged from the USB while holding
If there is sill no response it could be a dead battery. Plug it into the wall and let it charge for a while. Then unplug and press power, Vol +, and Vol - and hold it long. When you think it's been too long, keep holding.
It should take you to fastboot

Hard brick of Z5C ... can I save it?

Well, I did it this time.
In a valiant attempt to install a custom ROM, I erased every partition using fastboot,
Code:
fastboot erase system
fastboot erase boot
fastboot erase userdata
fastboot erase recovery
fastboot erase cache
Now what I meant to do here was flash a recovery, using
Code:
//fastboot flash recovery TWRP.img
but repeating this so many times over the last 48 hours, I did not do above and instead went quickly right into below,
Code:
fastboot reboot
The system rebooted as I told it to ... right into a black void of nothing. Now their is no 'recovery' image and no 'bootloader' image ... the phone is hard bricked, won't turn on at all, dead. I was so close to getting to the custom ROM! Is there any chance to get it back into recovery mode? or have I learned a $350 lesson?
Edit: Further research indicates it may be possible to force the system into fastboot using a USB jig. Has anyone tried this method?

Well, I did it this time.
In a valiant attempt to install a custom ROM, I erased every partition using fastboot,
Code:
fastboot erase system
fastboot erase boot
fastboot erase userdata
fastboot erase recovery
fastboot erase cache
Now what I meant to do here was flash a recovery, using
Code:
//fastboot flash recovery TWRP.img
but repeating this so many times over the last 48 hours, I did not do above and instead went quickly right into below,

When you plug it in while holding volume up what happens?

Nothing. LED flashes red every few seconds. The same response if plugging it in without holding volume up. Along these same lines, holding the power button on for a few seconds causes the small vibration haptic feedback to occur as if it is turning on normally ... but nothing happens the phone remains dead. Similarly, holding volume down and the power key causes a small vibration haptic feedback as it was booting into recovery ... but nothing happens the phone remains dead. I haven't seen anything on the screen appear, or the phone turn on it any way, since executing the fastboot sequence previously described.
Whatever you did, you should still be able to enter in flash mode and flash a stock firmware. And by this I mean full stock firmware, not a ROM.

Ok, that would be great. I would be thrilled to get the stock ROM back, at this point getting the phone to turn on at all would be a victory! Would you please describe precisely how to do enter flash mode with the phone in the current state? To reiterate, the phone will not turn on in any way (normally, or volume down + power to boot into recovery). The only life in the device is a slow blinking red LED when it's plugged in, and a quick vibration after holding the power button. The screen has not turned on in any way, or the LED shown any color other than red, since executing the fastboot sequence previously described.
hold power button + volume up and to force shutdown
and then hold volume up (or down, i don't quite remember) while connecting it to a pc (hold the button while connecting the usb cable).
If the led turns green or blue, congrats
The power key has nothing to do in this context. It is used only to boot into recovery or force OFF.
While holding VOL ↑, plug the USB cable to your PC to enter into fastboot mode (blue light)
While holding VOL ↓, plug the USB cable to your PC to enter into flash mode (green light, or maybe nothing)

Nothing. Device still unresponsive as described.
does your PC detect the device ? (new device sound notification)

No, the PC does not currently detect the device. All drivers are correctly installed as the phone was recognized accurately prior to the described fastboot sequence.
This is weird. I already erased everyting via fastboot too a while ago, and I could still flash it.
Just to be sure.... unplug all other "smart device" before anything (drivers can't handle more than one device at a time when it comes to FB or flash mode). Open the device manager and let it to the foreground. While you hold the vol down key, plug it and keep holding it until the device is detected. Don't expect any reaction on phone's screen, it remains OFF in both fastboot and flash mode. So, if the device manager reacts, you win.

I'm getting something here which is very encouraging! Executing your sequence causes the device manager to blink (refresh) as if it sees something, however no new devices are recognized in the tree. The phone LED goes to a solid green, reminiscent of a fully charged battery, stays on for about 30 seconds, briefly blinks red and then back to green, etc. The device manager is certainly reacting here it just doesn't recognize the device.
So here we are, you win. Because you have the "two", detection and green led. And if this state goes off after a certain time, it is normal. There is a kind of countdown and the device quits that mode if nothing is sent to it. You should be able to flash a firmware now with flashtool software.
Just ensure you have proper drivers installed properly (WinUSB drivers need to turn signature verification OFF before or Windows will block the installation)

Unbelievable! You saved me! I'm back up with the stock ROM and peace of mind to attempt the custom ROM process again. Saved me $350 ... thank you!!
That's great : )
It is almost impossible to hard brick a Xperia. If something goes wrong, remember flashtool ^^

Having some big problems - Need help please!!!!!

I got a replacement device from OP and I was unlocking the bootloader and rooting it. The guide i used had the incorrect patched boot image and everything went bad quick.
I can't go anywhere except fastboot now, can't boot to OS, no OS installed.
TWRP WAS booting from fastboot, I pushed the rom from there and flashed it...said no OS installed after, I installed it on both slots.
I can't get into EDL mode, the volume keys work...I think, but the second I let go of them when it's plugged in it defaults back to fastboot immediately. I tried the bat file that people use, says it worked, phone stays in fastboot.
I even tried holding the volume keys the entire time but the MSM tool wouldn't read it enough to flash anything, although it did read it enough to register some data, but was stuck on "waiting for device".
I am in need of some major help. Now I can't even temp boot to twrp, getting an error failed authorization. I'm afraid I really messed things up.
I have 5 days to send my old device back. Please help!
May be a longshot, but does the stock recovery work? Maybe try sideloading the full OTA zip from there?

For EDL mode, you need to hold the buttons then plug it in while continuing to hold the buttons. It won't work if the phone is already plugged into a usb port and then you try and get into EDL.
Really hard to brick a OnePlus device in my experience.

Recovery doesn't work. I was able to get to one of the steps to approve going into fastboot, advanced, reboot to fastboot, but not anymore.

I was doing just that. It seemed to work initially but after I plugged it in and released the buttons it went back to fastboot and disconnected from MSM.
Make sure MSM is ready keep vol up/down pressed, connect cable and immediately press Start in the tool. Have done it like this 3-4 times with my Pro

and this https://forum.xda-developers.com/showpost.php?p=82658631&postcount=85
both work for me.

I ended up using the fastboot ROM flash all.bat from this thread: https://forum.xda-developers.com/oneplus-8-pro/how-to/rom-stock-fastboot-roms-oneplus-8-pro-t4083997
I am now booting into the OS and the stock recovery came back. So good news is the phone isn't bricked.
Glad you sort it out
