Hi guys,
a week ago my ZUK Z1 started to bootloop without any evident reason.
I found it in this state picking it up from my pocket, so I guessed it was due to some random reboot that occasionally happened to it.
So, stating that:
- I'm with original stock CyanogenOS,
- I never rooted, or even accessed to the recovery menu prior to this event,
- I'm perfectly able now to communicate and send commands to device via adb or in fastboot mode,
problem is that I did NOT enable "USB debugging" and I did NOT OEM unlock when I had the chance to reach Developer options menu through the Android GUI (now I'm blocked by bootloop), resulting in an obvious "no unlocked device" error message each time I try to flash or write system partitions.
The output from "fastboot oem get-info" confirms this status.
I'm operating from a shell with adiministrator's grant in Windows 8.
No luck with "fastboot oem unlock", "fastboot flashing unlock_critical" or "adb root".
I used also "-i 0x2b4c" (vendor code) option in my commands.
Then, my question for you:
is there still a way to unlock bootloader in order to recover with CyanogenOS stock image, in this condition?
I saw there's a "debuggable" image on Cyanogen site, but I've no hint on how to use it and if it could help me.
Maybe ZUK has to provide to me an unlock key: I read on this forum that OnePlus and Huawei have similar option.
Thanks a lot in advance for any hint and suggestion you can give to me.

Sideload the official stock rom with zuk z1 tool. That s how i managed to un-brick my zuk. Download the stock rom , cm-12.1-YOG4PAS3OH-ham-signed.zip from this page https://cyngn.com/support. Use the toolkit provided here : http://forum.xda-developers.com/zuk-...alpha-t3235964 to sideload the rom. Wait until the phone restarts and thats it. You must also install adb and fastboot and have adb driver installed.I used the shenqi adb composite driver, but i guess the universal adb driver can work too. I had the same problem. Stuck in bootloop with USB debugging not enabled and bootloader locked.
Or you can try to fastboot the stock rom with the command provided in this useful tool.

Thanks a lot Extentho for your feedback.
I've already tried your fair suggestion: unfortunately, I'm stuck at the end of sideloading the signed .zip.
In fact, I see on screen logs that it's applying the update "unconditionally" (that sounds good), but nevertheless, when finished it returns "xfer: 1.00x" on PC shell and in recovery menu, on device.
Now, either if I reboot or power down and boot it again, the result is the same: still bootloop-ing.
Of course, at any other attempts leveraging on administrative privilege, it says that "device is locked", including those done through the shell tool.
Some excerpts from my last launched commands:

You must have the phone in sideload mode. There is an option to sideload in recovery menu.
Then use the command to sideload from the toolkit. The stock rom must pe renamed sideload and placed on desktop.
If the phone communicates in any way with pc, there is still hope. When you start the sideload process from pc, the phone should show an animation showing the flashing process. Post some pictures from where you are stuck, so i can make an idea about what is going on
my zuk z1 stuck to bootloop,
and android debugging is disabled.
phone can not detecting in fastboot mode.
please help.

I've tried also with the toolkit, but it's heavy bugged (also in 5.4 version) and, after all, it gets the exact same problem like me (not surprising, it launches my same commands ).
There's no useful image or snapshot I can share, because I see the animated green android logo moving its antennas on my device, while logs below saying that it's verifying package and then it's unconditionally overwriting system partition.
It seems all so normal and plain.
At the end of the process, no "installation complete" message, but simply I get back to recovery menu (where I started from).
In other attempts, I also wiped cache and user data, prior to rebooting, just to test if it was going to change something, but no luck.
The phone reboots, the "Cyanogen" logo starts to glow for 7/8 times and then... bzzzz, short vibration and all over again (i.e. bootloop).
I tried with an older official signed .zip from Cyanogen OS (cm-12.1-YOG4PAS3AJ-ham-signed, instead of newer cm-12.1-YOG4PAS3OH-ham-signed), but even worst, it fails at "verify package" step, aborting procedure.
MD5 signatures triple-checked each time versus source.
I saw some threads where it seems possible to change the bit, on system image, controlling developer option, to manually post-enable unlocking, but it's suitable only for Nexus or OnePlus One. No instructions for ZUK Z1.
Or maybe do I need a "donor" sharing a stock .zip with this option yet enabled?
Bootloop would be still there, but I possibly could enable to "flash", "boot" and "shell" vs the device, giving me much more options to try.
One last doubt anyway. If I press "Volume Down" + "Power" button at boot, I get into a menu like this:
http: // postimg.org/image/s5badiefh/ (remove extra spaces).
Viewing other examples posted on forums, I noted that at least the "Factory reset" is missing.
Could it be an hint for anything useful?

For me, this method worked exactly as described, booting into stock rom correctly.
now, if you mentioned it in the picture, there is another option. so, i ve noticed too this menu. There is an app called QPST wich can help you. Follow this thread: http://forum.xda-developers.com/zuk-z1/help/bricked-zuk-z1-t3277257 .
So when you enter in QFIL, connect the phone to computer and boot with volume down+ power into this menu from your picture. The Qfil app should detect some ports. You must choose the 9008 one, from what i have read.
Anyway, for me this method, didn t work because the pc couldn t detect the right port, only the zuk tookit did it for me.
You read the thread i suggested, and try that method, it may work for you.

Thanks again Extentho.
I saw QPST trick, but it's not catching right port and/or not getting right permission to stop phone from re-booting.
I think that adb/toolkit method should work also for me. I made attempts with other official ROMs: I noticed that for the older ones, the result is a bit different. They get stuck in a "black screen + notify led lighted in blue" state, rather than bootlooping.
Maybe erasing system partitions is needed, but I'm very reluctant to such dangerous way, without expertised advice.
Weirdest thing is that I did anything to get this situation, I just found my device in this mess.
Of course ZUK official support is well silent at my requests.

Try to post some pics about the troubles you encounter. If we receive a solution, this may be helpful for all of us in the future. Now, exactly, what can you acces on phone(recovery, fastboot, )?
Also, check varios threads from other phones with the same problems(one plus one, lg , htc) ,etc. Find a solved situation like yours, and we may adapt that solution to you
Hi guys,
Just to close this topic.
I was finally able to install the ZUI ROM through the QFIL program.
It's a little bit tricky, due to the fact that it is strongly suggested:
- to use a Windows 7 machine started without Signature Enforcement enabled;
- to start QFIL (admin mode) and be prepared with all needed files loaded in its GUI;
- to power off the phone, then, while pressing volume up button, inserting the USB cable, attached (better if) on a 2.0 port to PC;
- to be fast pressing "Download" button on QFIL program.
After that, I unlocked the bootloader and performed a lot of alternative recovery process.
So, I installed on the device:
- ZUI ROM
- Cyanogen OS convert from ZUI ROM
- Cyanogen OS last updated ROM
- CyanogenMod 12.1 last nightly ROM
- CyanogenMod 13.0 last nightly ROM
and the winner is...
...
...
...
... none of the above.
Each time the very same behaviour: bootloop. So, my last conclusion is: hardware failure (I guess wi-fi module).
I give up.
But for anyone searching a safe way to unlock a bootloader without accessing to developer options: the QFIL method works like a charm (once installed properly).
Thanks for support.
Messed my zuk z1
I tried to flash stock room in my zuk z1 , I downloaded Qualcomm file for the ROM and installed the required in my laptop,I wiped all data in my phone using TWRP .though my power button is not working I used tool kit to reboot my phone by connecting into fast boot mode,here comes the prob by mistake I entered the wrong command which locks my bootloader .I don't know what to do...help me.....
So I finally rooted my Oneplus 6t from t mobile. I bought the phone from swappa and it worked great. I installed a random rom and it bricked my phone.
I assume it is a soft brick since i can access adb mode but it requires me to power off the phone
and hold the volume keys along with the power button. Otherwise the phone will just boot up and
will be sutck in a continous boot loop. I then tried to fic this issue by using an msm tool found in
the xda fourms. I then entered recovery mode and perfomed a "wipe data/factory reset. I think it hurt more than it helped. Any suggestions on how to unbrick my phone?
I tried using alll three msm tools in this fourm.
when i use the msm tool (MSMDownloadTool 9.0v2) the update just stops after 4 secounds.
Also the update would fail if i were to use the msm tool (MSMDownloadTool 9.0v1 and MSMDownloadTool 9.0.13)
I have tried reinstalling the qualcom drivers but no luck.
I tried deleting the drivers and allowing windows to detect the phone nad download its own usb drivers
but it did not help.
i apologize if i post this in the wrong section. I am new here.
all links and info i followed to attemp to unbrick my phone can be found in this fourm

Okay so I open the msm tool. Then I have my oneplus 6t (t mobile) turned off. I hold both volume buttons and keep holding them while I connect the USB cable to the phone. Its basically in edl mode at this point. Then I press the start option on the msm tool. The bar fills up with green and completes itself. However a number appears that saids "4s" inside of the square. I assume that means 4 seconds left or completed in 4 seconds. My phone is still in edl mode at this time and will not boot up in any menu (normal.menu, boot menu/recovery mode). Unlesss I boot it manually.
And yes I tried a scenario where I held down both volume buttons, connected USB cord, and then let go. I also tried the scenario where I held both volume buttons, connected usb cord and kept holding the volume buttons until the process completed itself but I would get the same result. "4s"

Hi, Falzer. had all but given up and was prepared to head to T-Mobile to buy the 1+ 9 Pro (I almost wish I did not fix my phone... *BUT* I DID!
My issue occurred trying to flash a Magisk patched boot.img to my newly unlocked bootloader phone. I was following an article that alleged one could root the phone without TWRP. I will say this TWRP is your friend; don't dis "him". By the way, unlocking my phone wiped my data so always important to read the whole article first as it was mentioned in the NEXT step.
[Should be including the actual error here - it is found throughout these forums but I cannot recall the exact display. Basically, if you have an unlocked bootloader and then get to the CrashDump screen, follow from here:]
Retrieve the file, boot11.1.1.1.img and download from this thread/link:
OOS stable boot image and patched magisk boot image both for 11.1.1.1.
Leaving this here as i ended up boot looping from installing custom kernel, and it being a new release i was pulling my hair trying to figure this out. Flashed through fastboot with "fastboot flash boot_a XX.img, fastboot flash boot_b XX.img"...
forum.xda-developers.com
Do *NOT* mess with the other file to the right.
Hold all 3 buttons (2 volume buttons + power) and once/if you see Fastboot Mode, release the buttons.
Have ADB installed (you should be able to find plenty of directions for doing this).
From either PowerShell (or *maybe* CMD Prompt started as Administrator as I had been using this "successfully" for most functions):
fastboot devices
fastboot flash boot boot11.1.1.1.img
fastboot reboot
I could not believe my phone ACTUALLY booted (even with the McLaren animation intact; I'm sure one of the gurus here knows why) after all the failed attempts fooling around with MSM Download Tool [4.0] which almost EVERYONE swears by fixes/restores any brick. I understand ON ONE is forcing anyone to use any specific resolution; I am just trying to provide another last ditch effort.
EDIT/Caveat: I did not even check to see how old that thread above is, I believe late September and I had actually taken updates [via TMobile??] until the last one with a week to 10 days *but* that was probably wiped with the boot unlock so I do not know which "update" I got but figured I didn't have much to lose as I already had a "bad" version of a boot.img flashed anyway. Anyone with any technical explanations, feel free to comment. Thanks!
I was on A11.1.1.1 , when I decided to root my device. Tried to install Twrp but failed, then unlocked boot loader and flashed magisk using Adb from my windows 7 desktop. Phone restarted, went into bootloop, then restarted naturally - however I couldn’t turn on Wi-Fi. Downloaded SuperSU, which showed device was rooted. In an attempt to revert back to stock os, I flashed another boot image, and phone went into continuous boot loop. So I searched the web and downloaded Qualcomm hs-usb QDloader 9008, and MsmDownload tool v 4.0 in an attemp to unbrick my device and installed them. However, my desktop doesn’t recognise my phone as Qhusb_bulk or as Qualcomm qhusb qdloader9008 in devicemanager. So I m unable to use the MSM tool to un brick my phone. Tried reinstalling the drivers on desktop , but the phone doesnt show up on device manager still. Only shows up as “pci simple communications controller” under other devices.
When i turn on my phone, it shows the OP logo going round and round for 5mins, then the screen goes blank. If I keep the power off button pressed for quite sometime, phone restarts into boot loop again. Can’t get into boot loader, nor does adb on my desktop recognise the device.
i m at my wits end as to how I m gonna unbrick my phone, as this is my primary phone. Kindly guide me step by step as to how to unbrick my OP6t. Any help is appreciated.

When you get it to reboot did you try holding volume down as it starts? Should get you into recovery then bootloader.
Also get magisk to root rather than SuperSU. You can install twrp from magisk in oos with the correct installer but first you have to root correctly with modded boot.img. Can make your own or get from the one post in here. I'd suggest getting the newest oos also.

Probably need to flash a stock boot of 11.1.1.1 to unbrick. You can try booting to the newest twrp from fastboot I'm not sure if it works anymore.

Couldn’t fastboot into twrp, since device got corrupted while trying to flash multiple things. Thankfully while tinkering, my desktop recognised my device as qhusb qloader 9008, and all I had to do was boot my device into edl mode (which was also a pain tbh!). After trying numerous key combinations and timing it perfectly, device booted into edl and I could use the msm download tool to unbrick my device. Now device has rebooted into iOS 10.3.5 (same version as msm tool version) and I have somehow breathed a huge sigh of relief that my device could be resuscitated. Will be updating to 11.1.1.1 now (I see the latest is 11.1.2.2) and setting up my device now.
Thank you a lot for looking into my issue and suggesting solutions. In my younger years, I was a technology enthusiast and often rooted/flashed, but have pursued medicine since then. Now am out of touch completely to the tech scene and it was a grave blunder on my part to have used my primary driver to try and root/flash again.
Have a great day, my friend and please know that it means a lot to me to have received help from the community.

This happen to me several times and the first time it happened I thought my phone would not be unbricked after numerous attempts with the msm tool!
My issue was that my phone was a renewed amazon phone and amazon listed it as a unlocked international but it actually was a t-mobile variant and when i downloaded the correct msm tool with firmware it worked!
You need to get the phone into edl mode. For edl, when phone off press both volume buttons and plug in the usb while connected to your pc and the qualcom driver should pop up in device manager. After that finding the right msm firmware will be your next issue but with enough searching you should find it!
Let me know your progress with the driver and I can try and post some links to different msm firmware for the oneplus 6t!
Hello, I was going through stage to unlock bootloader, it was previously unlocked but a flashing error caused me to flash stock through MSMTool, I forgot to close/stop the tool after it was complete and upon one of the reboots it started the install again.. without realizing I attempted to boot the phone which caused the download to stop incomplete and booting to screen “upgrade download failed” I did select OEM unlocking in developer options as well as usb debugging although now it will not unlock bootloader; I can boot to bootloader not recovery and attempting to hold volume buttons while plugging into pc just pushing it to boot into the same fail screen. Is it possible to get my device into EDL mode so MSMTool can restart the install for stock? Thank you for any time given to help explain or direct.
Apologies if this is in the wrong thread

Apologies if this is in the wrong thread

Try using the MSM tool already started and the hold down VU/VD/Power until MSM grabs it.

This just boots to bootloader, from power off, any other combination instantly boots to same error page

It doesn't really matter what it does if you have it hooked up to your computer and have MSM turned on with start button. It can find your phone in a between mode and start installing. It works for me every time, just hit all 3 buttons from wherever you are as long as MSM is in the start mode, it will find it and start installing.

If MSM does not recognize your phone there is something wrong with your PC.

Use another USB Port and/ or another USB cable.
Dont use Windows11
Install latest Universal ADB Driver
Install latest Qualcomm Drivers
Install latest OnePlus drivers.
In fact the last thing that will NOT work is MSM. If MSM does not work your phone is completly dead. (Which yours is obviously not because it boots into bootloader) This means if MSM does not work, there is something wrong on your end.
Talking about dead devices, be etremly careful what you do in Fastboot mode!
[GUIDE] How to Avoid Killing Your OnePlus 8 Pro / 8T / 9R with OxygenOS 12 / ColorOS 12

Anything you do in the OS, like allowing OEM unlocking has **nothing** to do with MSM. In fact, a MSM flash will relock the bootloader. You will have to unlock again if you want to run anything except stock.
You have to boot the phone into EDL mode. Start MSM, then while holding the volume bar down, (UP and down, the entire button) plug into usb. Dont use the power button. (You may let volume keys go once done) There will be a dark screen, the only way to tell if in EDL mode is to check your device manager for the correct device. If you see anything on the screen you are not in EDL mode. I did use USB 2.0, do not use a hub.
I ask to start MSM first because on my Oneplus8, the EDL mode wont stay active for too long, unless MSM finds the phone.
If that does not work, put the phone into EDL mode and check your device manager (ports COM anf LPT) for QDLOADER 9008. Anything else, and the driver is not installed correctly and MSM won't work, If adb is working you can issue "adb reboot download" but the button press seems more applicable in your case.
There is a lot in the link below, it is for A10, I believe there is now a MSM for A11 but I have no experience with them.

I have tried all these and msm will not recognize the device in any state so Iv reverted to using a repair shop msm was successful in making the device stock the problem came from rebooting the device while msm was still connected and running. Pressing any button would lead to the download failed screen where the device is not recognized or into bootloader where oem is locked and even though before boot I checked unlocking enabled the fastboot command would not unlock the bootloader, if the store fix it I will try get details on what they did
I am Japanese and speak little English so I used deepl. Please forgive me for the long and difficult to read sentences...
This post was originally written as a question, but now that it's resolved, I'm documenting what I've tried to help anyone else having the same problem I'm having!
I recently inherited a broken Nexus 6P from a friend. I thought it was a cpu failure but apparently not.
symptoms
・If you press and hold the power button and try to start the device as usual, a white Google logo appears, followed by the following warning. The warning will disappear and the white Google logo will glow for a few seconds, then the screen will go blank and the white Google logo will appear again, and the loop will continue until the battery runs out.
⚠
Your device has loaded a different operating system.

・Fastboot will boot normally. When I start recovery mode from there, I get the following warning and then fall into the same loop as described above
⚠
Your device Is corrupt, It can't be trusted and may not work properly.

・The boot loader is locked and if you enter a command it will be rejected because you are not allowed to unlock the OEM lock.
・There are no articles about resolving this symptom, and Google Officials have not posted a solution.
・For this reason, it is not possible to install software by sideloading with ADB or to install a factory image with Fastboot.
Solution
・Force reinstall firmware using Qfil and then install Google factory image
What you need
・Tools to disassemble the nexus 6P
・Something to conduct electricity to short the board (I used tweezers).
・USB-C cable
・Windows PC
・Qfil
・Qpst
・Firmware to install with Qfil (search for Nexus 6P Qfil ROM) I'm not sure why some of them have Android version 5, but that's fine..
ATTENTION
I will not know if you fail and brick or destroy the device. Everything is at your own risk.
IMEI and other information will be lost and the device will only display “unknown”.
This means your Nexus 6P will no longer be usable as a phone.
method
Please install Qfil and Qpst and Qualcomm drivers on your computer beforehand！
Please pre-download both the Rom and Google factory images to be installed with Qfil!
1.Power off the device and remove the rear frame. (You can learn more about how to disassemble the device at ifixit, etc.)
2.Remove the screw securing the plate on the left side of the fingerprint sensor and take out the plate. (If successful you should be able to see three connectors)
3.Connect the USB cable to the PC with the two points on the board indicated by the arrows in the image shorted together
I have uploaded an image of the test point. We will use this test point for this work. Also, do not allow the metal that shorts the test point to come in contact with any metal other than the test point. It is very dangerous.
4.Keep shorting until Qfil recognizes the device. When recognized, it will display Qualcomm HS-USB QDLoader 9008
5.Select FlatBuild. xml, mbn or other files and press the download button. At this time, put your computer in airplane mode and keep it off the network (I don't know if this makes sense, but it worked this way)
If you want to know more about the procedure here, search for other people's articles...
6.Download succeed
Finish Download
If it looks like this, you have succeeded. The device should now be bootable; boot in Fastboot mode (the Fastboot screen will look weird, but it's ok).
7.Enter the following Fastboot command on your computer
fastboot oem unlock
If the device shows LOCKED and nothing else changes, but the PC shows Okay, you have succeeded.
8.Download your favorite version of the factory image from Google. Once downloaded, unzip and run install.bat.
9.The device will automatically restart and resurrection.
