Have a Samsung Galaxy Tab (Verizon) SCH-I800 7" that is stuck in a reboot loop. Searches/fixes for this issue seem almost common, but mine is experiencing this issue much worse than the others I've read about. Full charge, not plugged in; without pressing the power button, the device automatically attempts to turn on, the Samsung logo appears for 5 seconds exactly, it shuts itself off, the process repeats until the battery dies. Battery at all levels, plugged in; without pressing the power button, the device automatically attempts to turn on, an empty battery image displays for roughly 4 seconds and then a full battery (or current level) displays for roughly 1 second.
The 5 seconds while it is on, pressing or holding the power button has no affect. Pressing and holding the power + down volume buttons will display the yellow downloading screen, which displays "downloading.... do not turn off target" and yellow android sign for 2-5 seconds (depending on how quickly I am able to load it". While this downloading screen is displayed, pressing power, volume up or down do not have any affect.
When connecting the Tab device to a computer via the USB cord, the computer recognizes it for approximately 4-5 seconds, then disconnects for 4-5 seconds, repeat forever. The computer is unable to successfully install drivers or do anything useful in this short amount of time. The battery has been replaced as well as I thought that may be the issue, no change.
Any suggestions?
"Pressing and holding the power + down volume buttons will display the yellow downloading screen, which displays "downloading.... do not turn off target" and yellow android sign for 2-5 seconds"
are you saying it turns off after few second even in that download mode?!
what have you done to your phone before that?
are you on stock firmware? version of ROM?
even tho i don't think i am able to help you, but more info my give someone else a better chance on doing so

Click to expand...
Click to collapse
well, i have experienced this, after i flash a ROM, and my battery is low, i forced it to flash, and became the same like your tab....
maybe this step can help your tab...
1.charge your battery for 3-5 hours
2.after that, quickly hold the power + down volume to download mode
3.connect it with your computer, Restock it
PS: IF after step 1 try to normally boot your tab, maybe there still a hope:angel:
Good afternoon,
I'm facing a problem on my colleague's LG L90 phone, it suddenly started to bootloop and nothing seems to solve the problem.
The only way to turn it off is to remove the battery, but as soon as you put it back (be it instantly after removing it or after any period of time) the phone turns on and starts to bootloop again, so there's no "turn it off and turn on again pressing x buttons". The bootloop lasts about 10 seconds before it restarts the process.
When I connect it to my PC with the battery nothing changes, and the PC doesn't recognize the device, as it reboots before the PC can see it. Plugging it without the battery shows a screen with an empty battery for some seconds and then it reboots, showing that screen again.
I tried to enter recovery mode, emergency mode and fastboot mode without success. Plugging the phone on the PC or placing the battery while pressing vol -, vol +, both or any with the power button simply has no effect on the phone, it just keeps bootlooping.
The phone model is LG-D410hn, and it doesn't have unlocked bootloader, root or anything similar, it has everything stock.
Does anyone know what I can do to try to save it?
Hard reset is volume- & power pressed for a short moment, letting both keys go and instantly pressing both again. Solved my bootloop problem.
Hi, I recently flashed the new Ubuntu Touch image for the Xperia Z1 without any issues, but then my battery died after a few days of no usage and I can't get the phone to boot, nor can I get it into fastboot or recovery: When I put it on charge, first the notification-LED starts blinking red, then after a few minutes it begins starting up to charging mode (battery icon). Pressing any volume buttons while the Sony logo shows doesn't help, and after that the phone begins totally bugging around. I can't get it to boot to Ubuntu, but I also can't get it to turn back off without waiting until the battery drains, and then I'm back at plugging it in again. I also tried hitting buttons while plugging in the USB-cable, but again, no results.
Any suggestions? Thanks in advance.
I have an htc m7_ul with s-off. I tried updating to lolipop using PN07IMG_M7_UL_L50_SENSE60_MR_HTC_Europe_7.19.401.51_Radio_4T.35.3218.16_10.33Q.1718.01L_release_458803_unsigned.zip which failed in some parts of the flashing process and put my phone into RUU only mode.
After that I managed to flash M7_UL_JB_50_HTC_Europe_1.20.401.1_Radio_4A.13.3227.06_10.27.1127.01_release_308001_signed_2_4 which completed SUCCESSFULL without any errors. The phone rebooted and hopefully Htc quietly briliant logo appear and everything seems fine. Unfortunately this wasn't the case, the phone stuck in there. I try pushing several buttons power, power + vol up or power + vol down for several minutes but nothing. The phone was stucked on quietly brilliant logo. I waited until the battery fully drained and charge it for a while, I tried to start the phone again the phone couldn't boot up the only reaction it has is the capacitive buttons blinking whatever combinations of power buttons and volume buttons I used. The phone is not recognized in pc at all its like is completely dead (it is not even being detected in device manager) . Is there something I can to? I really tryed everything and search in forums for hours for an answer without any luck.
Update:
I am not sure if the phone is being charge since when I connect it to wall charger there is no red led light. Something I didn't mentioned is that before updating to lolipop I was on stock kitkat without root just unlocked bootloader and S-OFF using rumrunner. Any help will be appreciated !!
Update 2:
I left the phone alone and fully discharged, now when I put it on charger the red led blinks (turning on/off). I read that this led must stay solid red in order to get some charge. Its has been more than 5 hours and the red led didnt become solid red. I tried everything the forum solutions advice but without any luck.
Update 3:
I disconnected the phone from charger and weirdly the red led blinks (turning on/off) continues even is not connected to charger? Can anyone help me its urgent
I have Xperia Z3+ dual E6533 that was on custom ROM working fine for almost 4 months.
suddenly after installing Xposed framework second day while on ultra stamina mode once I try to deactivate it and go back to normal it goes into boot loop.
once I turn off the phone and let it charge to 100% tried again to boot but still the same so I left the phone for a couple of hours to be cool down after around 15 min boot loop.
suddenly it's not responding anymore for any key combination or hard reset or reflash.
I tried hard reset by the small button next to sim card slot, by (Power & Volume +), by removing the battery and reinstall it again.
now the computer does not recognize the phone at all and cannot go in flash mode or fastboot mode.
I tried also holding the volume- before connecting the phone and holding it until connecting to PC but nothing showing in device manager.
now all that is coming that once it's connected to wall charger it's blinking red for 2 days now and while pressing the power button the blinking red light turns into stable one not blinking.
I have already read most of the similar issues written for other devices and tried most of them but still nothing.
can anyone help me?
