ZUK Z1 Entered an endless restart loop

Hey guys,
I was hoping you might help me as I was struggling to find an answer through google search.
After using the ZUK Z1 (Cyanogen OS 12.1 with the latest update), a few days ago the phone suddenly restarted and entered an endless restart loop
I've tried wiping the data, the cache and the user files.
I've tried applying the latest CyanogenOS zip for the Z1 either through sideload or locally from the device.
Nothing worked and I'm becoming very frustrated
I thought that maybe if I could wipe the system partition and then apply the COS zip than maybe it would work.
Does anybody have any ideas?
Thanks in advance,
Yoav.

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-z1/development/win-zuk-z1-toolkit-0-1-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 too.

Can you tell me what exactly did you do?
As far as I can see nothing works for me with the toolkit...
Did you use a mac or windows?
I checked that the driver is recognized (ShenQI), also tried manually using fastboot commands to unlock the bootloader and flashing images, but since my device is bricked I am unable to allow OEM unlock from inside Android
Update:
So I came across a discussion in this forum about bringing a bricked ZUK back to life
http://forum.xda-developers.com/zuk-z1/development/how-to-flash-zuk-z1-zui-version-t3265741
Done that, seem to be successful, however the phone won't turn on and the QPST Configuration tool shows that the device is stuck in download mode.

Does anyone has any idea what that means? Does that mean that it is a hardware failure?

Ok, so first, don t panic. If you re able to acces recovery and fastboot mode, there is a strong hope. I have Windows 7 on my PC, btw.
I tried the qpst tool to flash the stock, but i couldn t. That is why i turned to the Zuk Tool Kit, which did the trick for me.
To use this tool, FIRST OF ALL YOU MUST INSTALL ADB AND FASTBOOT. you can find varius tutorials about this on te interent. I provide you some, too:
http://forum.xda-developers.com/showthread.php?t=2588979
http://lifehacker.com/the-easiest-way-to-install-androids-adb-and-fastboot-to-1586992378
http://www.howtogeek.com/125769/how-to-install-and-use-abd-the-android-debug-bridge-utility/
It was hard for me too to understand what is going on at first, but i did some research on the topic, and i got it.
After you installed adb, you can check if it is instaled by running the command "adb version" in CMD:
You should recieve something like this if it is installed.
After you installed fastboot and adb, install the Zuk Toolkit following the steps provided in the thread of Lenvo Zuk toolkit. Download cygwin, open cygwin terminal and drag start.sh from zuk toolkit folder into terminal window, press Enter, and you will have the menu open like this:
Here, just naviagte by writing the number corresponding to the menu you want to access and hitting enter.
Under "6. Do some basic ADB and Fastboot commands.
" coomands, you will have this menu:
Do note that [fASTBOOT] marked commands will work only when your phone is in fastboot mode. To acces your fast boot mode of your phone, just select "reboot to bootloader" option from recovery menu.
Once you managed to reach this state, you can put your phone in fastboot mode, and try the command "10. [Fastboot] Reflash to stock using a manually downloaded factory image."....
IF this doesn t work, try to flash the stock rom via sideload option from recovery menu of your phone. To do this, you must chose the sideload option from recovery menu. Download the stock signed rom from here https://cyngn.com/support(NOT THE FASTBOOT ONE, JUST THE SIGNED ONE.) Rename your stock rom zip file you just downloaded "sideload" and place it on desktop. Then use THE command "4. [ADB] Sideload a zip file.
" from zuk toolkit to flash the rom. Also you must have the phone connected to pc with the USB-c cable during the whole process, of course. If it works, your phone will show the animation of flashing procees on its screen. Wait until the phone stops, chose wipe dalvik and reboot.
Use the snipping tool or PrtSc to take screen images from where you are stuck or you don t know what to do, and post them here.

Well, the QPST method seemed to have worked (as indicated by the QFIN tool).
However, it seems that the bootloop is back, when I am only able to boot into the ZUI recovery without any option of fastboot.
Edit:
Here is a pic of the Recovery (there is no option of adb sideload)
http: //s10.postimg. org/flaa11g3d/IMG_20160120_121012.jpg
Here is the fastboot
http: //s22.postimg. org/rgz4rt3a9/IMG_20160120_122555.jpg
And this is what i get when I try to use fastboot commands
C:\ WINDOWS\ system32> fastboot -i 0x2b4c oem device-info

You have the ZUI version?? Because this does not seem to be the stock recovery of cyanogen. At least, i have the option to sideload in my recovery.
When you chose the install Update pacakge option, what options are displayed on your phone?
Also, if u installed qpst, you shoudl have in your PC a program callled QFIL, which is the flasher tool for all lenovos including ZUK. You must flash the zui stock rom using qfil. Read this thread for more info and downloads: http://forum.xda-developers.com/zuk...ui-version-t3265741/post64865607#post64865607
Also, here is a thread of a guy who had pretty much the same problem as you and managed to flash the stoc using QFIL : http://forum.xda-developers.com/zuk-z1/help/bricked-zuk-z1-t3277257

Yeah, it was cyanogen and with QFIN I flashed stock ZUI in hopes that it will the bootloop.
I contacted coolicool, which is from where I bought the device.
I will send the device to them. I hope that they'll be able to find the problem.

I think you could try un-bricking it by yourself. It is not that hard. But if those guys from coolicool will change your phone, that s ok too. Blease be advised that rooting voids warranty...soo

Lucky me I didn't have the chance to do it
I didn't even have the chance to unlock the bootloader
Does anyone here have any experience with the guys over at coolicool?

i flashed coldbird's zip for capacitive touch on the fingerprint sensor. got into an endless restart loop after that. to every option, the toolkit replies command not found.
eg: ./xposeduninstallbootloop.sh: line 128: adb: command not found
followed by whatever option was ordered, that has been done successfully but can see no change.

Try this

Easy bro easy, the steps that you are following are a bit confusing, aren't they?
Please tell me the current status of your phone. I might be able to help.

[GUIDE][TOOL] Reboot to EDL mode from FASTBOOT! No More "Test Point Method"! [kenzo]

[GUIDE][TOOL] Reboot to EDL mode from FASTBOOT! No More "Test Point Method"! [kenzo]
Reboot to EDL mode from FASTBOOT!
No more Test Point Method needed ​
Technical Details:
Redmi Note 3 support rebooting to EDL in Android Bootloader aboot module (the "reboot-edl" command) but fastboot utility doesn't recognize "reboot-edl" in the command line and refuses to sent the command to the device. Since FastBoot command protocol is simple and text-based, it is enough to send a packet containing "reboot-edl" text over USB. The simplest way to do that is to patch Windows fastboot.exe file, replacing "reboot-bootloader" text with "reboot-edl". As "reboot-bootloader" string is found in the command line, fastboot.exe sends the same constant string to the device. So if "reboot-bootloader" is replaced with "reboot-edl", you can specify "reboot-edl" in the command line and the same text will be sent to the device.
New Update: Fastboot updated to latest version.
Tutorial:
1. Download the Fastboot_edl-v2.zip from Here.
2. Extract the zip in your desktop
3. Open the folder and double Click on Reboot.bat

}
4. Reboot your device to Fastboot Mode by pressing
Vol Down + Power button and connect your device with PC and Press Enter.
5. Your Device will be rebooted to EDL!
6. Now flash your Fastboot Rom with Mi Flash Tool to Unbrick your Mi Note 3. ​
Proof:
Thanks to @emuzychenko for the Idea!

This is AWESOME!! Just tested and worked amazingly.
Thank you!
Edit: the included command prompt didn't work for me though, launched standard and traversed to this folder

You can find it in the fastboot rom. Or if you have recovery rom, then go to the firmware-update folder in the zip there you will find it.

Maybe stupid question, but wouldn't phone go to edl mode (with red led flashing) before flashing rom and what then mbn file has to do? According to your manual it is the last step?

Is your device bricked or you want to flash an official miui rom? Since your rom looks like a distributor rom not an official rom.

No, my device is not bricked, it has locked bootloader. I received code from xiaomi to unlocked bootloader but it constantly stops at 50%, and I found out that it can't be unlocked without china dev rom, but no rom can be installed with locked bootloader I only want to flash an official miui rom to be able to receive updates...Xiaomi really made this too complicated....

Don't use this tool if your device is not bricked, your rom is a distributor rom that's why you cannot unlock your device, you have to flash miui rom prior to unlocking, you can do it thru edl mode using adb, search on miui forums and you'll find it.

If your device is not bricked, then you can reboot to EDL mode from adb. Do this to reboot to edl from adb:
1. Connect your device to PC.
2. Open adb and type: adb devices and press enter to see your device if it is connected properly.
3. When you can see your device ID, type: adb reboot edl and press enter. It will reboot your device to EDL mode.
4. Now flash your rom with Mi Flash.

well, i think this caused by relocking bootloader after we flash a new firmware. if that happens, just go in fastboot mode by hold power button + volume down, then unlock it again using mi unlock. reboot it..your twrp is back.
no need to enter edl mode & install twrp again, btw thanks..this is helpful

don't flash official miui from twrp (you better do it in edl mode), but yes you can flash custom miui like miui eu, miuipro, multirom, epic miui etc from twrp. and..after u delete the emmc file inside the firmware which is included on every miui rom, your bootloader will be safe

Probably the problem with bootloader file

not a whole lot of talk anywhere else so i'll try here. i just got my kenzo few days ago, jumped the gun and started trying to get twrp on it. i'm assuming the bootloader was locked. As of right now it wont boot up, its in edl mode maybe... red led flashes and i can upgrade driver to 9008. sometimes its recognized by miflash and when it is and i try to flash stock fastboot it gives me an error. i know thats a lot to take in but i'm trying to cover all my bases. the phone came from overseas so sending it back isnt really an option. any help is appreciated.

Does the rom link given here unzips perfectly?
Because i saw in another thread of Lenovo K8note titled firmware, users unable to unzip due to error in system img. Also downloading from baidu needs a user id. If its possible could you or anyone else reading this upload it in some other online storage drive. Im little bit worried about getting a worse situation while rooting. Even if it goes wrong i can use the stock firmware to make it back.

Yes, I think so. Anyhow there is no need to unlock oem again if you are flashing the rom via TWRP. Anyhow let someone confirm about it.

No need to unlock bootloader again if you use fastboot method to flash stock firmware , & for spflashtool I'm not sure but I think it remains unlocked

Try to boot it again in the full system and from there try to unlock your bootloader.
If you done that, reinstall the software.

How can I unlock bootloader without fastboot? If I attempt to enter fastboot or anything that requires reboot I end up on that screen.

Hmm....
Have you tried rebooting to fastboot using adb?

Hello
tested with the toolkit 0.0.0.12.
to see if he recognizes the phone.
he should at least write your serial number.
if that is the case.
you can use DC-unlocker. to open FRP and can be the bootloader.
just an idea.

Dc unlocker needs cash and it doesn t always work.

I am doubting buying DC,unlocker in case,it doesn't work and I will lose money.... I will try toolkit.

3 button upgrade doesn't work either.

I have the same problem after I tried to relock my bootloader using SRKToolHuawei-STABLE-V1.3-20160619 with my bootloader code.
Have you found a solution?
I can boot back into os b394 after I let the battery run out to 0%
I haven't found a way to repair my recovery and fastboot yet because rebooting into fastboot always get's me back to that first error
Func NO: 11 (recovery image)
Error NO: 2 (load failed!)
Then I have to wait for my battery to run out again
Any help to get fast boot and a working recovery back would be appreciated.

Use Huawei multi tool ,then flash system, custom,recovery image ,
If stock recovery opens then use Dload method

I got stock recovery back with the warning that my device is unlocked. Now I get stuck at 'Your device is booting now'. After some time it reboots and opens eRecovery which I cannot use.
How do I get anything on my phone to continue with dload and which firmware would you advice me to flash if I finally get there.
Should I, if even possible at the moment, choose an older firmware version?
Edit: Would the original service rom help? Found it here https://forum.xda-developers.com/huawei-p9lite/help/original-service-rom-huawei-p9-lite-vns-t3688120 but my build number seems too high as the version I need only mentions b381 and b383 not the 394 I currently have..

Same problem for me
No way to shutdown the phone, someone have solved?
Now I'm waiting for the battery to full drain

Hi guys i ve made mistake because i wanted to update to latest release media pad m3 but i could not be able to boot to stock recovery after i flash recovery img extracted from update.app and second time i flash recovery2.img to erecovery partition and i got the same issue error Func No 11(recovery image) and Error NO 2 (load failed) . I also put the update.app to dload folder on sd card but update system is not starting i press volume up and down and power button at same time but is not working.I tried also with huawei multitool but is not working is not recognize my device. Please guys is any other solution to fix this ?Thank You!

I just fixed after power off device and then press volume down and plug the usb cable to pc and i was able to recognize my device and i have use huawei multiTool to unbrick my tablet media pad m3 and has work.

Almost the same problem, help please!!!
Hi guys someone can help me? I have a Honor 9 lite(LLD-L31). Android version 8.0
I apologize but I'm a new user and i don't have much practice with modding in general.
I tried to install root permission in my device. I get bootloader unlock code by DC-unlocker and installed TWPR on my device.
When i went in recovery the error " Failed to unmount '/system'(Device or resource busy)" rushed, so I tried to format data in order to give partition available. I tried again to flash file.zip but the search was empty so I downloaded a most recent version(3.2.3) of TWPR in recovery ramdisk.
Now if i try to log into recovery mode appear the same error (Error! func NO 11 / NO 2).
I can do everything aside going in recovery mode. How can I resolve it? Is it possible to reset to factory settings and try again?
I hope I have explained well the problem.

Could you write down the steps you took to get back in fastboot for me? I'm having troule geting there myself after draining battery.

I fixed it after nothing else here worked.
So this is mostly so I dont ever forget the solution again, but also to possibly help others.
I also have to say that I had the problem with an P8 Lite, but all my problems matched almost exaclty, so It might help you too.
And a third disclaimer: I have no idea if you can flash the stock firmware without having the bootloader unlocked.
If you dont have it unlocked, try this wonderful updated guide: [Links are disabled for me so google this: "Droidhunter unlock huawei bootloader" and pick the article by droithunter.com]
And yes DC-Unlocker, suprisingly actually works (at least for me) and buying their bootloader unlock code was worth the 4 bucks.
So here is the solution:
1. Somehow, however needed get into fastboot. As I couldn't use the volume/power key combo myself, I somehow force reset the phone, pressing various buttons until I managed to boot into it again. I then used the adb bridge to boot into fastboot (google how to connect adb, then use "adb reboot bootloader" to get into the fastboot menu).
2. Download your phone models default stock rom/Update.app (also google that).
3. Extract the Update.app file.
4. Download and use the HuaweiUpdateExtractor tool and open the Update.app file (google again helps).
5. Select the "09.recovery.img" entry (the one with the green arrow on the left), rightclick and select "extract selected" and save it somewhere where you can find it.
6. Open your Fastboot console on PC (its often the same as the ADB console used before, especially if you use Minimal Fastboot and ADB, which I would recommend).
7. Make sure your phone is in Fastboot mode (not recovery) and connected to the pc.
7.1 Make sure your bootloader is unlocked. It might work with a locked one because youre just flashing stock firmware but eh might break more. Its worth the 4 bucks to unlock the bootloader first. (and yes DC unlocker looks super sketchy but somehow it actually worked for me and wasnt a scam).
8. Flash a custom recovery onto the phone (pretty much the same way you flash twrp, but instead of the twrp image you use the .img file you just extracted from the Update.app; Also dont try flashing twrp directly, it will probably not work).
The command to do so is: "fastboot flash recovery [filepath to the .img file without the brackets]".
9. Use the command "fastboot reboot".
10. If your phone doesnt boot normally, use the key combinations to get into the normal recovery screen and recover from a file or whatever (other guides should work from here).
Extra Steps:
As my recovery image was obviously so broken that even flashing twrp on top of it didnt work until I flashed the original reovery image, I went into my phones settings and did a factory reset. Directly after I installed twrps (see google) and set it up so it had full control. Afterwards I rooted and installed LinageOS cause frick EMUI rn).
Hope this helps anyone. If you have any questions feel free to ask me.
