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 everyone!
4 days ago i washed my phone for about 10 seconds, phone worked normally. After 1 hour i saw water went into both front and back camera. I got out all flaps and after some hours cameras were functional again. After even more hours buttons started to act weird. Sometimes power button wasn't working, sometimes volume up was acting like power button and so on. I tried to restart the phone, sometimes it went into safe mode(probably volume button was pressed by itself). Finally I couldn't start the phone at all(perhaps the power button stopped working at all).
After that i calmed down and put my phone into rice(hoping that would absorb water if any). After 24 hours i had no luck. When i had connected my phone to computer, the led was red, phone vibrated 3 times and then again and again.
Next step was to open the phone( removing the back with a hairdryer), took out the battery and trying to dry the phone with hairdryer. Still no succes. When connecting to PC and start flashtool, my phone wasn't recognised. I installed Sony Update Service (SUS) and then when i connected my phone i heard that sound you often hear when connecting a new device to an USB port. Now my phone is seen by flashtool, but it's always in fastbootmode. I even flashed CWM and it worked.
The problem is that it seems volume up is pressed always so i can't enter in flashmode to flash 4.4.2, it always goes into fastboot.
When on battery the phone is dead at all. Still when i try to charge the phone, it starts, displays Sony logo then shows that it's charging (at first that battery was empty but after 2 hours it got full charged). If i press power button it shutdown.
To resume, when on battery nothing happens( the battery could be dead). When plugged to wall charger the phone starts charging( so battery could work). Power button does nothing at all when on battery, but works when phone is charging or when connected to PC in fastboot.
If anyone had any idea what I could do I would be very appreciative. If you have any questions don't hesitate to ask me.Thank you very much for your support!

Even if i down't press anything, just connect the phone to usb, led is blue, that means it's in fastboot mode...so i think volume up is stuck, pressed.

or the volume pcb might have shorted
Please remember this for the rest of your life:
When you notice that water has went into your device.... TURN IT THE F OFF AND LET TIT DRY...
Using it while it's wet from the inside is really bad.
Update Guys
Today I've replaced that yellow connector that contains power, vol up and vol down buttons. I managed to enter flashmode and flashed the newest official rom .233. Power button and vol up work like charm, vol down is dead.
The problem is that my phone is stuck on safe mode(probably because vol down is stuck). I want to know if there's any solution to get rid of this safe mode. I read somewhere that changes can be made to the kernel so that vol down will be disabled for ever. If you know any ROM, any mod, whatever that disables the vol down button i'll appreciate your help.
Hello. This morning I've turned off the alarm, turned on WIFI and went back to sleep. I can't tell for sure, but I think the battery was low. During the next 2 hours I checked the time several times. I don't remember accepting any OTA. Eventually I got up, tried to check the time and the phone was off. I tried to turn it on, no effect. No matter how many times and for how long I pressed and held the power button, the green LED only flashed for a split second and that's all. I plugged in the charger, and the LED stayed lit -but- there was this barely noticeable flickering. Charged it for about 30, 60, 120 minutes, didn't start plugged or unplugged. I went to work, 8 hours later (phone was unplugged) I tried to turn it on again, this time the LED doesn't even flash, but when charging there is no flickering. No combination of buttons works. Windows doesn't find the device, neither does RSD.
I've never done anything 'custom' to the phone. The last change I made was setting the alarm to turn off by shaking (yesterday, never used this option before).
Is it dead?
Try taking SD card out and holding Vol down and then Power for 20 secs, then let go of Power,
Already done that, nothing. No matter how long I charge it now, after unplugging and pressing power button the LED doesn't even flash. Could it be a battery problem (before its death, it would last for a day)? Is there any way of recovering my data without buying a new one?
Try opening and disconnect battery for a bit.
I'll do that as a last resort, on weekend maybe since I don't have the tools with me. Any other clues?
Nobody knows how to help me?
I'm going to make a factory cable. Will this alone allow me to recover the data? Or if I'll be able to flash the phone, can I recover the data afterwards?
Also, I'm not sure if I understand correctly: does the factory cable recharge the battery or not? Is there a way to recharge it when removed from the phone?
Try to use medfield unbrick script. If You have only green led it seems to be bootloader error so this script should bring Your phone to life or Your phone has broken emmc and You can start looking for a new logic board. Good luck.
I've installed the drivers, but Windows and XFSTK don't recognize my device at all. Factory cable also didn't help. I liked my phone very much. :angel:
Did You enter medfield mode using combination with camera button??
By a combination you mean holding the camera button and connecting the phone to a pc? I tried that.
Disassembe Your phone, pull out battery, push power button for a 10 sec, plug in battery, push camera button and connect USB. If it wont help You I don't see any hope for Your phone.
Well, new option to try is a new hope. I'll try that on the weekend. Could you please be more specific:
1. Pull out the battery.
2. Press the power button and wait 10 seconds.
3. Insert the battery: should I be still holding the power button at this moment?
4. Press the camera button.
5. Plug in the usb cable (factory? regular?) - should I be still holding the power and camera buttons?
Battery trick is only to discharge capacitors. Sometimes even phone is dead it can turn on in some strange mode and then You can't boot it to flash. Thats why You need to pull out battery, push power for a few sec to completely discharge motherboard and just release this button. After that You can just plug in battery and continue normal unbrick process - so hold camera button only and connect regular usb cable.
You can also try reset option instead of pulling battery out. To do that do not disassemble Your phone but just plug in regular USB, when phone starts (green led) hold power and vol- until green led goes off and then quickly start holding only camera button.
I have no more ideas.
Ok, I've tried everything. Nothing brought my phone back to life.
Thanks for all your help.
Hey guys,
I've got a M7 that is stuck bootlooping. It's fully stock, absolutely untouched and of course out of guarantee time
The phone started the behavior after running out of battery.
The phone does start automatically when connected to power source and shows the htc logo and then vibrates and the cycle begins. The touch buttons do not light up.
I can get into boot menu, though I'm unable to select any of the options as the phone quickly reboots again. The led is neither alight nor blinking when connected to power.
The phone doesn't show reaction to any button/light combination when not connected to power. I've tried the following combinations:
power+up 2min
power+down 2min
power+up+down+light 15sec
So anything else i can try?
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?
I reflashed the stock firmware on my phone after it was throwing some errors on boot, and once it got to the Updating... screen it changed to Erasing... and was stuck for over an hour before I did a force shutdown. After that it entered download mode one time (in which I did not do anything with odin) and now:
Turns on and gets stuck on the Note5 splash screen when plugged in or put on a charging pad, force shutdown works in this state.
No change to the above when holding vol+ and - or any other button combo before charging
Power button does nothing outside force shutdown, it will not boot off the charger when holding it nor do recovery or download mode shortcuts work
None of this changes after running flat and recharging
The buttons were all functional before, so I am guessing they still work. Have I hard bricked it?
