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.

Boot animation or simply mi logo and then vibrating and again rebooting???
If mi flash tool shows successfully done without any errors then
Try this
Roeboot to fast boot and type
fastboot oem unlock-go
I guess it will be fixed

I am stuck at boot animation with the three white dots spinning for ever ? will try to do as you said

I tried fastboot oem unlock-go but i get response: token verification failed and device still stuck on bootanimation

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

tips to avoid relocking bootloader, when u want to flash a new firmware..just delete emmc apsbot.mbn file inside the firmware using winrar or etc, or u can use psy-man firmware because the emmc file has been deleted

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.

Bootloader Unlock [Snapdragon Only]

This is an initial work in progress which may or may not work for you. This worked for me and it may cause brick on other devices if tried. So don't try this unless you are ready to take the risk. And whatever happens i won't take the blame.
What is it?
When you unlock your device, mi unlock tool writes the unlock code in the devinfo partition. This is a partition dump of my device in its officially unlocked state. If you still wish to follow this guide, then continue or else look somewhere else. Again this is only tested on my device and may or may not work for you.
Download: Here
Extract the files.
Run your phone in edl mode
Open device manager or miflash and note your port number.
example: com10 or com4
run the unlock.bat file.
it will ask port number, enter the port number.
example: com10 or com4.
and press enter.
If your phone is in edl mode and has a proper port alloted with qualcomm hs-usb qdloader 9008(%port no%)
everything should work fine.
Will upload a few screen shots later.

Is your phone fine...no bootloops or anything wrong.

Wait for a few days and ill try to mod it to be universal.
For info it works fine in mine. I used it to unlock and the device was working fine.

No. It was my partition dump and i unlocked officially.
I dont know why people say they have trouble unlocking.
My only trouble was that i had to wait a while to get the unlock permission.
And my other problem that without using miunlock i cant unlock it again.
I mean everytime i have to unlock i have to login to that damn program.

Yes just flash 6.11.3 using edl. Then use miunlock tool to unlock. It will work without any problem.
Some who tried to flash my partition either had no changes, bootloader remained locked or either had bootloops in which they had to flash using edl again.
Yes that will work.

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.

Rename it​************************************ No long name, space, special characters.*********************************

Launch MIFLASH and install drivers

Select Rom folder
_________________________________________________________________________________________
Start the phone in fastboot mode(press and hold the power button and volume down button at the same time) and plug in to the pc.
REFRESH
Check the box at the bottom right CLEAN ALL.
Flash the rom.
At the end of the flash, miflash indicates an error (normal, no problem).
error:Not catch checkpoint (\$fastboot -s .* lock),flash is not done
the phone restarts unplug in.
​

Or easier one click method (which i prefer) if miflash gives some errors in flashing or installing.
Just connect phone in fastboot to pc, open fastboot rom and click on bat files to flash.

If I want to lock the bootloader (EU version) and return the phone to its stock state, then I have to select 'clean all and lock' or is there a specific reason on why selecting 'clean all'?

(unlock or lock erase data)

I did this when I first got the phone and flashed stock EU rom, Will do it again if no one else responds with any other methods, and I really need to use phone and hassle each time to set everything up after reflashing
Thanks

Hi, I'm trying to flash stock MIUI so i can do a clean flash of another custom ROM. But I'm stuck with an error that's MiFlash Tool is giving me.. The error says: Length cannot be less than zero. Parameter name: length. Does anyone know a fix for this? When i try to double click the flash_all bat my cmd just closes instantly when it opens. Pretty new to this so I'm worried i might brick something. Thanks

Did you use the last Miflash?
Did you rename the rom folder?
did you use usb 2 port?
is the phone in fastboot mode?

Yes, latest MiFlash and called the folder 1204. I've tried both usb 2 and 3 with no luck. My phone is in fastboot mode but I must say i tried flashing the stock rom with XiaomiTool v2 since it did recognize my phone but it gave an error while flashing the super.img. So I'm pretty scared if ill reboot it will be stuck.

Also installed all drivers neccesary with my device called android phone -> android bootloader interface in Device Manager

This is surely the first attempt with XiaomiTool v2 that blocks, try to restart and then reflash with Miflash.
Anyway you will not be able to reset it without restarting
Make sure the ROM file has been extracted completely with no corrupted files.
Extract the ROM file in the root directory such as drive C:\ or D:\.
Make sure no single space in the folder name path.
Ensure the Mi Flash tool is run as Administrator (Right-click > Run as administrator).

Flashing wont work because everytime i press refresh my phone doesn't show up and it gives me the error length can not be less than zero. Tried putting it directly in C:/ too. Thanks for taking your time btw I'm really grateful. I'm also a bit hesitant of restarting my phone because of fear for bootloops. Is that the only option you know?

My end goal is to flash the new hentai OS with android 12 and i was wondering (since i know how to do adb sideload) if i could sideload it now when it's in fastboot. Or should i try to firstly fix going back to stock MIUI?
