Zuk Z1 went dark

So i have bought my phone about 3 months ago. All have worked well, but a couple off days ago, it have had some problems.
It sayed 2-3 days trebuchet process have stopped and process.android.process.media has stopped. The only solution when this came i had to restart the device. I tried yesterday a factory reset but it didnt work.
Yesterday evening it did again the process stopps and then i tried to restart my phone. But when it shut down it dosent anymore go on. Now it dosent react to anything, not the normal powerbutton and not even the powerbutton + volume -. I havent rooted the device. So is there anything i could anymore do or should i just send it to warranty repair?
Im very desperate, thanks for all the help. But if you have an solution can you write it step by step, im not so experienced in smartphones.

Now i got the phone to restart but when it start it says over and over again that trebuchet has stopped. What can i do to this problem?
Edit: And now its stucked in the Zuk start screen. Dam im getting frustated...

Enter in recovery mode and do a factory/cache wipe
Have you installed any themes? Because some cm13 compatible themes cause system ui crashing

Hello, havent installed any themes. How do i get to recovery mode?
If the recovery mode is volume up and power button. This neither works, its still dead. Dosent even vibrate when pressing power button long.

Power on the phone , when you hear the vibration and the zuk logo appears , press both volume buttons, this should let you boot in the recovery
What happens if you connect the fone to charger?

But the phone dosent power on. So i cant do that. And no, the battery is not dead.

Ok, if you cant boot it, the last thing is warranty , where have you bought your device?

I could boot it today on the morning 1 time but then it again died and now its totally dead. I bought it thru tomtop, have put a message to the seller already. Lets se what they answer.

Ok, hope the seller will answer you , continue trying to boot it .
Let me know if wou solve it ��

Yeah the seller answered that i get a new device. But then on tuesday i tried a last boot, and it got alive again! I did the factory reset and now the phone has worked perfectly after that [emoji106]

But now the trebuchet keeps stopping and after that all the processes i have open. So now i changed to Nova launcher, i hope it would solve the problem.

Glad to know you solved the problem
Trebuchet problemi shoul be solved with marsmallow update.

Yeah it was solved like 5 days. Now the apps started to crash again :crying: And now the f***** phone dosent even start. Its just stuck in the Zuk powered by android start screen. Is there something i could do? I dont think the factory reset would help in long term beacause it didnt help the last time. Or should i just send the phone to the seller and request for a new one?
Edit: And now the factory reset dosent even work. When i try to reboot it after Factory reset its stuck on the Cyanogen start screen, so i think my last option is to ship the phone to the seller and hope i get a new device.
Edit2: And now after a second factory reset the phone started to work again. What can cause this type of meltdown? Could it be somekind of hardware problem or is it a software problem?

The Best solution is to change the device if you can, because you're not sure if it will work in the future.

Note 3 SM-N900L bootloop issue

hi guys..so I was using phronesis rom on my Korean note 3 with custom kernel..when I used to turn the phone on it to say set warranty bit kernel on the top and used to get stuck at the logo then I would remove the battery and turn it on again and it would turn on..but yesterday my phone turned off automatically and was stuck in bootloop.it was not booting into twrp..so I flashed stock rom via odin but the bootloop was still there and I can not boot into recovery it would just restart and go back to booting normally and again bootloop..but if I remove the battery for a few minutes and then turn it on it works fine until i turn it off..now
thanks in advance.

From what I can tell, a possible issue you could have is with the battery. I used to have this problem, my phone would re-start for no apparent reason, couldn't even get to recovery. I switched the battery for another and it worked again. So maybe you could try that

Before trying anything, simply put the phone in a freezer for 1 hour, then try to put the phone in download mode.

urgent help! oppo a37f

Hello people on Xda! I just bought a oppo a37f and it's was working okay until I turned it off, when I turned it off it just kept on going to bootloop. So I flashed many official firmwares using the Qualcomm tools and also the official tool for oppo. But everytime I flash sometimes it will come up with the setup screen everything works until 3 mins later it lags and sometimes have a black screen so then I force restart it (volume down + power) then it's the same again bootloop. I've really tried all possibilities that I could think of and hours and hours of researching on how to fix this. And I don't want this phone to go to waste.
So if you know how to fix this kind of problem then any advice would be good

Maybe it's a hardware issue
