[Q] Stuck in the google logo screen

hello people
the tablet became unresponsive to touch, hung by power, and then it is locked on the screen with the logo of google.
he enters the "fastboot" (Power + V down), but does not go into "recovery mode".
When you select the "recovery mode", but the tablet restarts back to the screen of google.
I did the steps with the "fastboot" by cmd, he said all right, but after restarting returns to the logo of google.
I did the procedure with the Nexus Root Toolkit, in (back to stock) option ... all steps are given as "OK" .... but again the google logo screen.
after several hours trying, android booted out of nowhere ... but again without running the touch ... rebooted again, and so far there is still only showing the logo of google.
I saw that there are several other topics with the same problem but in my case, nor the recovery works ...
anyone have an idea of what can be?
asus RMA does not cover my country ...
I read that some cases that is the motherboard tablet ... someone has more knowledge?
sorry for my bad english

hi guys, I have the same problem
It must be something with the bootlaoder since the google logo is part of the bootloader and recovery. Fortunately it is possible to flash a new os, bootloader, recovery and kernel at the same time. See this thread (not the first few pages but the ones after) http://forum.xda-developers.com/showthread.php?t=2546558

I had LITERALLY the very same problem, and ended up having to RMA to Asus, where they had to replace the motherboard. They said the problem was caused by a LED (Error) Indicator. Not sure what that means exactly, but it was a physical issue with the board (I had a remanufactured device). I was able to get into fastboot just like you. ADB would recognize, I tried pushing images like you, everything completed ok, and it would not budge. When I selected Recovery from the Fastboot menu, it would just reboot and lock at the image again. Not sure a software fix is going to work for you. (I assume if possible, Asus would have saved themselves the cost of replacing the whole board.)

How to fix blocked boot recovery samsung?

Hello guys,
A few months ago, I rooted my phone using kingroot. After a few weeks, i tried to install TWRP custom recover to unlock bootloader. I accidently downloaded a wrong version of it and flashed it using flashify app, after which i booted into recovery to check the new recover mode. But, something awkward happened. THE BOOT MODE DIDN'T OPEN AND THE SCREEN GOT STUCK AT "Booting into recovery". I read on the internet and realised that my device has got soft-bricked. Also, phone wasn't rebooting. So, i found a solution atleast start my phone. I took out my battery, pressed the buttons for download mode and then placed the battery back in and pressed the buttons for download mode and somewhow rebooted my phone (i read about this technique in xda forums). Now, although my phone works but i cannot access the recovery mode as it has got soft-bricked. Thus, i cannot perform a hard reset as it gets caught in that "recovery booting stuck cycle". So, can anyone tell me how to fix this? PLS QUICKLY. aLSO, i don't know much about ADB, so pls explain that too as my friend suggested me to use ADB to fix softbrick but im not sure!!

OnePlus 3 gets stuck on OnePlus logo screen when trying to boot.

Like the title says, my phones gets stuck at the oneplus logo screen when trying to boot after unlocking the bootloader and
installing a recovery.img file trough the command prompt all after doing a factory reset. After this I tried going into recovery mode
but it just gets stuck at the oneplus logo screen and then the screen just turns black. At this point if i were to try and go straight into fastboot mode it wont let me. Instead i have to long press the power button to get back into the options menu but that's about all i can do. Any help would be greatly appreciated.
This is due to a faulty recovery file may be twrp 3.0.4 so use the recovery I'm attaching to flash and that should fix it... Looks like my net speed is slow so just download twrp 3.0.2 and flash that

Hard Bricked ( flashed TWRP and locked bootloader )

I first unlocked the bootloader and then flashed the TWRP image, later I flashed AEX 4.6 ROM and then I thought or reclocking the bootloader but when I did it's not booting up. The ZUK Logo appears for a second and screen goes black, the led remains lit and holding the power button for 10 seconds doesn't turn of the device , it restarts again and same thing happens.
Im not able to even access EDL(Emergency Download Mode) to use QPST or MiFlash tool.
Help me guys...
You should really learn to use "FORUM SEARCH". This kind of issue has been resolved and there are few guides available too.
