[Q] Yureka boot loop - YU Yureka Q&A, Help & Troubleshooting

After downloading the update my yureka started restarting always as long as the battery is in contact. It shows the cyanogen logo and reboot again till the cyanogen logo appears and then reboots. I was able to get to recovery but it doesn't stay till I wipe or do anything IT REBOOTS all the time. PC doesn't detect when connected.

Yu yureka bootloop

Hi friends,
I rooted my yu yureka two days ago. It was working fine and i was still on cyanogen os 12.1 .
I used this thread to root and install cwm recovery.
http://forum.xda-developers.com/yureka/development/tool-one-toolbox-yu-yureka-t3087186
Yesterday I restarted the phone (first reboot since rooting) it powered off and then the yu logo came on screen.
The device vibrates and it is stuck on logo. The logo remains as it is and the notification led is turned red for some time then it is gone.
The vibration is continuous and it would probably not stop till battery gets exhausted. I did not wait that long because i feared permanent damage to the hardware.
I am not able to access recovery. But i am able to get into fastboot mode.
What to do now to restore the device to normal operating conditions?
Is my device bricked?
Note : my device is on official cyanogen version 12.1 all software is original and after rooting i installed only greenify app.
Flash cm12.1 by fastboot method.

hello i'm facing an issue with my zuk z1. I flashed zui 2.5 rom in it through qpst and also unlocked my bootloader and flashed twrp it was just working fine, then i decided to flash the nougat firmware because i was getting some random reboots.
today i flashed a firmware(nougat) for ham and then twrp asked me for reboot i selected reboot and selected system (i usually power it off and then power it on manually) and after that it just started booting up infinite times it just shows a penguin logo for just a fraction of second and automatically reboots in just 2-3 seconds and also vibrated while rebooting
Please help me what should i do ?
Whenever I install COS 12.1, my phone went to bootloop
Phone works fine in Nougat and zui but whenever I install cos via fastboot or twrp, it went to bootloop.
Any solutions???
Also any link for Qfil COS 12.1 room?

Help! Galaxy S7 Edge bricked...

Hello all. Since nougat update my phone has started having boot up issues. I had software update a month ago and after it was updated it failed to boot up. It just froze on Samsung logo screen and i had to wait for the battery to drain to start it again. So that time it started after a good few tries. Now last night it had another software update and again after it was finished it rebooted and failed to boot up. Gets stuck on logo screen/ samsung screen. I tried booting in safe mode.. nothing ... gets stuck again on black screen and have to wait for battery to drain. When it gets stuck i can't do anything not even reboot with any of the buttons. I've tried going into recovery mode but once it boots in recovery it shows Installing System Update or something simmilar and in 1 second gets stuck untill battery is drained again. So basically i can't do anything on it. It won't boot up in normal/safe mode or recovery mode... Any suggestions ? I've tried samsung switch on my PC but it needs the phone into recovery mode and i can't get this far. What else is there to do ?

Stuck in bootloop

Hi,
I was using RR-5.8.3 in my lenovo a6000,
3- days back
Phone used to restart when i start clicking photo using flash
2-days back
phone used to restart when i open several apps
Yesterday
Phone started restarting when ever i open lock --restart again when i try to open lock(IN loop)
after a while it started to restart in lenovo boot logo itself(BootLoop)
after that I re installed the OS too, But still problem is exist.!!
I can access twrp 3.1 recovery, but the problem is that even when i use twrp the phone automatically restarts and gets stuck in boot loop
Help me!!!!!!!!!!!!!!!!!
I have exactly the same issue and since exactly the same day. Is it a coincidence or something else? Developers.....please help !!

Bootlooping when not in charge..

Started Suddenly my a6000 plus went off and was not starting at all. I was running RR rom. I didn't install or modified anything prior to the problem. The interesting part is when I put it on charge and try to start, it starts with bootlooping but after sometime boots in system. But can't get into recovery. Now after starting if I plug out the charger it immediately shuts down and goes into bootloop. Now without putting it on charge it never goes into system. I can't get into recovery, only bootloader is showing up and fastboot commands are working but not adb. I tried Qdownloader but pc isn't recognizing phone as driver is not getting installed. What should I do?
Have you found a solution? I am facing a similar issue on stock, non-rooted. It keeps flashing the boot logo but when connected to power it boots in system. As soon as power is removed it keeps blinking the bootlogo aka bootloop.
