Dear XDA friends,
i always hoped not to be one of those guys, who f****d up their phones to the point of no return. I really screwed up this time. Well, here I'am writing you about my screw up.
I unlocked, rooted, flashed and repaired all kinds of android phones in the past years, never without problems, but I could always fix it somehow. Not so much this time.
Now I'm stuck at Bootscreen with the Zuk logo. I even have problems pinging the phone via ADB.
Sorry for my noobish question guys. Any help would be much appreciated.

I got this translated from a chinese website:
For fastboot mode:
The phone turned off; keep the connection turned off the data cable to the computer, press: [volume down key] [Power Key] waiting to enter the fastboot mode.
For recovery:
Turn off the device
Press and hold Power key
When vibrates Volume UP key + Volume Down key about 10 seconds
Release all key when Android logo appear then you will see Android System Recovery
Use Volume key to select Menu
Use Power key to Confirm
Can you enter any of these 2 modes?

The bootloop is just showing the ''ZUK logo'' in the middle of screen and "'powered by Android logo'' below,and the phone vibrates everytime it flashes these logos. I tried QFIL but it can only detects the unit on the first boot or first flash that is 2 secs. only from the time i press the power button, and then it disconnects and not detect the unit again. Does anyone know where can i find the scatter file , MTK ROM for zuk z1, i would like to try the SP flasher tool. Or if anyone have any idea how to solve this issue on lenovo zuk z1,pls. help.tnx
Can y get to fastboot ?
im facing the same problem after i had the stupid idea to lock the bootloader again, before that i flashed the phone successfully with the cm mod recovery and cm 13.
Has anyone found a solution to this ? or do i have to send it back ?
What i did exactly :
I locked the bootloader again and just to test it i tried flashing the recovery again , ofcourse it didn't work which was what i wanted.
Afterwards i rebootet the bootloader with sudo fastboot -i 0x2b4c reboot
now im stuck in a bootloop that i cant even stop , in other words i cant turn my phone off nor can i access the recovery or fastboot
Im feeling so stupid that i locked it again .... i will try to get into recovery after my phone ran out of battery but so far it looks quite bad...does anyone know if i will get a replacement even though it was my fault ? ( i don't need to say that it was my fault ..and the bootloader is now locked again )
UPDATE::
I found a promising thread about this problem, i will report back here if i was successful.

Please help , same problem
I am facing same issue too from 2 days. I didnt even try to flash custom roms or play with boot loader or recovery or anything. All of a sudden my phone entered boot loop. After two three bootloops phone is entering "12 apps optimized of 230 apps" mode, completing optimizing all apps and then failing to start apps, entering boot loop again.
Effort made so far to fix -
1) Went to recovery and cleared cache - didnt work
2) Went to recovery and did factory reset - factory reset did happen but boot loop didnt stop, I realized that factory reset happened because now its saying optimizing 120 apps instead of my 230 apps during the bootloop.
3) Went to recovery, Entered fast boot mode but not able to connect to PC. Fastboot devices is not showing anything. I made sure proper driver is installed after researching on XDA.
4) Went to recovery, Tried "Install update". Didnt install anything but browsed through folder structure and realized my data is intact
It will be great if someone can help me atleast recover my data before I handover phone to service center for fixing boot loop issue.
Same problem

Sorry For Re-posting Here. This is Solution
Why this is happening ?
Due to Dirty Flash from Zui or from COS/CMOD but suddenly Bootloader gets locked
May be Due to Some Custom Rom which only works with Old Bootloader ( And you are on latest 2.5 Zui QPST Flash)
Reasons are many. I also did same mistake. I flashed ZUI 2.5 using QPST then unlock bootloader using official site installed twrp after wiping cache system and data , Installed Lineage 0S JAN Build then without rebooting installed Lineage Nightly build (Latest) with Gapps After rebooting Phone goes into Restart endless loop on ZUK Logo. Blink and Vibrate .. After 1hr I figured it out but its 5am So slept.
HOW TO FIX ENDLESS REBOOT ON ZUK Logo ?
-> Identity vibrate patterns (Press Power Key I count 6- 7 Vibration pattern ) After long Vibrate immediately remove finger from power key.
->Once its Done (Phone completely off)
Download QPST and Official COS QPST from this Link https://goo.gl/InWQji OR https://goo.gl/iqrnlI (I am personally Very Thankful to D tech Terminal for posting Wonderful video on Youtube https://www.youtube.com/watch?v=4Dl6JkAVpuM
<- please install all drivers and software.->) @ankurpandeyvns Thanks bro.
Main Task is here and Lots of Patience is required and You also need to be very Blazing fast to achieve this.
-Once you download and install Qpst open Qfil
-Now press Volume Up only and connect USB (Just press POWER KEY only for 1 sec It will vibrate and connect)
-Without waiting hit Download button.
-Voila It will start flashing your phone again and Hence Your phone is now Revive..
-Once Revive You can use it to again flash custom Rom or stick to stock Rom if you want.
Keep Flashing !!!
Patience is Key here. And Don't lose hope.
:good:
EDITED:
While connecting to pc and by pressing Volume key you also need to press Power key for 1 sec or 2 sec until it gets detected. Thanks addicted777 (for tip)

Hi all,
I have a particularly tricky case here. A OnePlus 3T with a broken screen (its black, can't tell if its registering taps) which I need to recovery data (photos) from. Normally I'd just use ADB but of course usb-debugging isn't enabled. I've tried rebooting into recovery... hold the power button and vol-down until the phone vibrates, keep holding for a few seconds. Then wait. Then vol down twice and power again to hopefully select English but the when I try
Code:
adb devices
nothing comes up on the list.
I'm wondering if anyone has any ideas how I can recover data/photos from this device.
One again the facts are:
-OnePlus 3T
-screen is broken, black, doesn't display anything
-usb-debugging is NOT enabled
-i can see the device in fastboot mode (boot w/ vol-up+power)
Thanks!
Maybe try a mouse with OTG. Would be horribly difficult i guess. But can probably work.
Also with any recovery, it would require your pin to enter the recovery (for decrypting the partitions); so that's a no go.
All you can try is to just boot the phone normally and try any input with an external mouse with OTG. Bring it to a point where the phone is powered on and unlocked so that you can copy data off the flash storage in MTP mode.
Ps: why don't you try to normally boot the phone and use fingerprint unlock?
did you trying with this link?

Using this tutorial in this case would make no sense, since the damage is physical and this way you're going to lose all the data currently stored on the phone.

if you have no usb-debugging and cannot see screen you are out of luck. same thing happen to me. the only thing that worked was I had twrp recovery and was able to boot into it. Recovery by default is in mtp so you will be able to see all your folders and transfer pics or backup files. last resort was to send it to oneplus repair which will cost about 100 bucks and you will get your phone back within 7 days remember to tell them to not reset phone because they will if you dont. good luck
You can also recover the data very easy through data recovery softwares. No usb-debugging and cannot see screen you are out of luck. I also have to face same problem the only thing that worked was I had twrp recovery and was able to boot into it.
You can try to flash TWRP in fastboot, then reboot recovery via fastboot command. MTP would work unless a pin is required in TWRP.
I can feel the situation,the phone doesn't work properly.
Hi,
Tonight, I tried unlocking my bootloader with adb. I did the usual thing (OEM Unlock on, USB debugging enabled, adb devices, fastboot oem unlock). However when I tried fastboot oem unlock, it says < waiting for any device >. I tried installing the USB driver that came with the phone when you plug it to PC. I tried fastboot oem unlock again and same result. I googled it a little bit and I found that you need to enter fastboot mode. So I decided to power off the device and boot into fastboot mode. However, when I tried Vol Up + Power button combo, it won't enter fastboot mode at all. There's no 1+ splash logo or anything, it just won't turn on at all.
The device was connected to my laptop and I noticed a driver was being installed on my laptop as the device was being turned off. It was QCOM BULK or something. Now whenever I connect my phone to my laptop, it's detected as Qualcomm HS-USB QDLoader 9008(COM7). adb devices won't list my device now. I also tried other button combination (vol down + power button, vol up + power button, just power button, vol up + vol down + power, etc) and my phone won't boot at all.
I'm extremely sure it isn't hardware or liquid damage, because the phone was working 100% flawlessly before I powered off my phone with OEM unlock enabled condition.
Please help me, I literally just got this device 4 days ago. I don't want to brick a 4 days old $550 device. I saved up all my money to get this phone. There's no official OnePlus service center in my country, so I probably need to send it to other country to fix it which will be very expensive and I won't have phone to use for weeks.
Any help is appreciated. Thanks
EDIT: I tried charging the phone for 15 minutes, it still won't turn on
EDIT 2: MY DEVICE IS FIXED! I fixed it by holding vol up + power button for a few minutes. I really thought it was dead, that was the most intense 2 hours of 2019 lol. Thank you to whoever wrote this thread -> https://forum.xda-developers.com/oneplus-6t/help/soooo-tmo-variant-6t-bricked-simple-t3866487/page2
You should not be trying to unlock your bootloader via adb. The unlock process is done via fastboot.
And before you attempt any fastboot operation, type fastboot devices in your terminal screen and hit enter to see if your phone is detected.
I had this problem and power with vol + for about 3-5 sec will reboot

This, but my phone was like 15 seconds.
if the above options dont work, you can try the MSMDownloadTool. That should reflash everything on the phone and let it boot. There is a walkthrough for it somewhere on the forum. Not sure which section though.
Hello i am trying to root my 1year old heavy used phone . I am Stuck at the very first step.
Also it should be mentioned that it got a little bit wet by rain someday and then the volume down button was stuck (not mechanicly) it forced the volume setting to zero and had no sound.
I soft reset it . Than no change. had a hard time getting into recovery but i finally got there somehow i dont remember how.
Then hard reset it.No change....
After one day the volume key fixed itself and everything is working fine.
now after one month i was curious if i could root it. But i am not able to get into bootloader state.
I tried everything.
Debug options and oem bootloader unlock switch enabled, usb debugging enabled.
Usb adb says no permission (serial n visible)
Entering Recovery mode at power off state by
Pressing vol up and power button gets normal boot everytime but much faster logo visible at about 3sec.
pressing power + vol down = it takes 25sec
Booting normal .. and the same happens when pressing both vol keys.
I am releasing the keys at zte logo visible everytime
Something was strange : one time when i was trying something it bootlooped 3 times and then it was safe mode.
could there something in the volume button be broken? but the button work fine. I dont know.
Thanks for reading
update:
ok the permissions was a linux issue(start the adb-daemon with su), i can use adb now on this phone,
i can boot it in recovery now, but cant boot into bootloader
adb reboot bootloader leads to normal boot
in recovery, the reboot into bootloader option also normal boot
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
