Hello,
This is my first post so i hope that this is the right place.
I have a serious problem. My K910 is endlessly rebooting.
It all started after i updated android from 4.2.2 to 4.4.2 When device rebooted after installation it never came further than lenovo logo.
When phone turns on, it vibrates, then lenovo logo comes out for 2-3 seconds then it dissapears and the loop starts again.
it shuts down only when i push power button and volume- button multiple times.
I have tried to enter recovery/safe mode, but with no results phone keeps rebooting.
I reinstalled battery but still as i turn the phone on, same problem occurs.
As soon as i connect my phone to pc phone turns on and endless loop starts again.
Questions:
How can i change to stock ROM or connect to PC in this situation since it keeps on rebooting my pc doesnt see added device?
What can i do to fix this situation?
Please Help.
I promise $feedback if this thing can be fixed

That means your phone is in bootloop. Try opening recovery and wipe cache/data . If you got a custom recovery, then its much better.
Hello,

after i removed it too much,
fixed by replacing it,
hope it helps.

I'm using the Samsung Galaxy 10.1 Tab (Verizon) SCH-i905
From what I have read, the reboot loop is when the user sees the boot screen, but the tablet keeps on rebooting. My problem is severely worse.
My tablet keeps on reboots, but it doesn't show the boot screen. Instead, it just shows a blank lit up screen.
Not only that, but I cannot always turn on my tablet. I keep trying, but it typically turns on after I keep plugging and unplugging the USB from my outlet to computer, and so forth (for about 10 minutes). When it finally boots, I can go into Odin mode. I flash some sort of firmware to it, and then my device turns off. And I need to keep attempting to turn it on again for 10 minutes before it actually turns on.
Nevertheless, my device still does not work properly. I know this is infact a software problem because my device was working fine yesterday, until I decided to unmount and mount certain things in Recovery mode.
So far, I have flashed recovery.tar.md5 , PDA_SIGNED_P7105.tar, and 75XX_CWM_Recovery_v5.1.2.6.tar. None of these have fixed the problem. How can I return to factory settings?
I just saw the previous thread about this device and am currently installing PDA_HC31_EG0 ... If everything goes right, then there should be no problem. But I highly suspect that the firmware will flash successfully, and then my device will proceed to power off for another 10-15 minutes before turning on again.
If I leave my device plugged into the power source, it will start turning on and off (the blank lit screen) periodically. For example, turns on for 5 seconds, then turns off for 5 seconds (and repeat).
While this is a software problem, it seems to be on the OS level. Are there any other ROM Links besides the ROM in showthread.php?t=1342995 that I should try? Also, is there any other possible alternative?
My phone is NOT on bootloop or brick. But instead every time I restart or on my phone the Samsung logo blinks for a while(1-2min) before it boots up. Tried looking up but cannnot find any answer. I am on Cyanogenmod ver. 10.
I tried to go in to recovery but cannot it keeps flashing on samsung logo. (all my buttons are working fine) I have CWM recovery. Just it just flash/blink for a while then restart again.
Is it a Hardware problem ? Please help!
You turned off your phone till it vibrates/pull out battery and then volume up+home+power button for about 20 minutes?

Sounds like it can also be because of software problem, most likely some form of corruption that causes the Samsung boot logo to reappear continuously. Try flashing a different rom and see if it helps or clean install the rom again

Hi,
my LG L40 is stuck in kind of a loop. I can't get past the LG Logo. I tried to factory reset it via Vol down + Power button and got into the user menu for the factory reset but when I start the reset it the phone just powers off.
When I first try to charge it, it says the battery is at 74%. But after I tried to factory reset it won't charge at all, it just shows the charging screen for 2 seconds then turns off and boots again into the charging screen. Repeat infinite.
I can't get into download mode either.
After getting the battery out for some time and putting it back in I get a working charging screen, but if I then try to factory reset the phone again it will be stuck in the charging screen loop again.
When the charging screen is working and the phone is connected to the PC it installs drivers for a "battery charging device" or something like that. I couldn't access the phone in any way from my pc, though.
Is there anything I can do?
The last owner of the phone said, it was just working fine and then started behaving like this suddenly. He says it might be a battery problem. I can't test that though. Would've to buy a new battery. Maybe he is lying?
Any help is very appriciated! Thanks in advance!
Try to flash it!
Got to downloadmode and flash stock ROM.

Google is a good way to start, I googled "lg l40 bricked" and got this, maybe you should try it? I recommend a cse flash.
Hi,
So my S3 stopped working a few weeks ago while I was on holiday. It fell from my hand and turned off on its own. After that I turned it back on and it was working fine for a couple of minutes, then the problem started happening.
Every time I opened an app that used the camera, the phone would reboot. After a couple of reboots, it would get stuck repeating the Samsung logo (haven't been able to boot it since then). When I plug the charger in, it passes the Samsung logo and then stays on the Cyanogen mod logo. I've left it on for hours on the CM logo without any luck. I can't boot into recovery mode because the vol. up button doesn't work, and I can't get adb to find the device on my pc (though it does charge when plugged into the pc).
All I'm wondering is if there's a way I can save my media files from the phone myself, or if I need to take it to a service centre.
Tl;dr - phone loops samsung logo when on battery, gets stuck on cm logo when charging, vol. up broken so can't get into recovery mode, adb won't find the device so no recovery mode like that either, want to save media files.
Any help is appreciated. Thanks

Hi all,
To get right to the point, my phone doesn't switch on, and I cannot get into recovery/download mode.
The story:
After my apps kept on crashing for no reason, I restarted the phone. After the restart, when it asked my pin, the google app kept on crashing and the phone completely froze up.
Here is where I suspect I made a HUGE mistake. I Took out the battery and started up the phone again. It immediately told me that the system is corrupt and "cannot be trusted".
I continue the boot process, only to land in a boot loop. I take out the battery once again and restart the phone.
After displaying the LG logo, it just turned off. And that was the last time I could get it on.
I tried booting into recovery, but the phone won't even switch on to begin with.
Absolutely no response. Screen stays pitch black.
I tried doing it with the USB cable in, same result. Nothing.
I also read up on the different combinations to get into download mode to no avail.
Stock ROM and firmware installed, no mods whatsoever.
Android 8.0
Can anyone please suggest anything I can do to save my device?
