You have to press the home button and the power button together
Thanks for replying. But this is not working. Only doing screenshots.
Sorry, I misread Try to restart the phone
Thanks, but nothing isn't working, i try factory reset and reeboting too. Now I dowloading firmware from sammobile.com. I hope that fix it. I think of that broken some module from Xposed. Sorry for my english.
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)

I installed Lineage 7.1.1 and I am on the latest build for 2-14-17 on G900T.
I have an issue where my home, back button and the app switch button does not work. A quick reboot would fix it, but that's not working anymore.
Installed button savior and that helped, but I would love my buttons back. Can someone please tell me how to fix this?
