Hi guys Ive got a new problem with my nexus 4 (this time not user inflicted :angel on friday my phone was at 80% battery and i turned it off, it had been working fine these past few weeks but now it wont turn back on, i've tried the following things:
Charging overnight with original charger from the mains
holding the buttons in all combinations then putting the charge lead in and holding them for at least 30secs
The phone doesn't have a notification light of any kind
Any advice would be greatly appreciated
ps the bootloader is unlocked so i guess sending it back isn't an option
Some people have said they sent it back with unlocked bootloader without issues. I don't see the issue as long as you still have stock.
You can try removing the battery and reinserting it, then charge. Or replacing the battery.

Ok thanks i might try that
Ive called lg and im going to send the phone in under warranty, ill let you know how it goes:fingers-crossed:
I think I got the same problem -kinda. I clicked reboot and then went on to stare at my laptop screen for a while. The last thing I notice is that it's at the bootanimation. The next time I look at it again, it's dark. well, of course, since I naturally thought the screen is off but the problem is nothing happens no matter what I do -just like OP. oh, and there's no blinking red light or whatever.
One thing I notice is that the device is listed under adb. If the device is off shouldn't there be nothing listed there? So, is this damn device still turned on?

Your ADB is enabled but is not activated for your connected device, it is activate by the popup notification in the phone.
Do a factory reset.
sometimes for some whatever reason phones can get stuck in adb sideload mode(i saw only 2 phones do that, and one was GS3 with cm installer, the other was an old galaxy ace).get a rom zip and take a look and see if adb sideload Works.
fixed it. I've charged it the whole night before I posted that screenie. I've approved the rsa fingerprint or whatever before the phone dies so technically it should connect since I've even pushed some files around before that. What i'm trying to point out is that even though the phone is dead(?), why does it appear under adb? I could fathom fastboot but adb? So all the while I'm charging it overnight and frantically raping the power button pressing it like some nuts, the N4 is actually booted up? damn.
Anyway, I charged it for a couple more hours since my last post and then just now, I pressed the power button for about a minute (connected to pc) and suddenly the notification on my pc went nuts. It's saying the N4 is being connected and disconnected over and over again -goes on for about a minute and all the while the cursed red light appears though it goes off after a while. Hit the power button again after the light disappeared and voila -it booted up normally like nothing happened :curses: --talk about acting innocent.
Tried doing some reading on why it even happened but I don't get it at all. Oh well, whatever. I just hope it doesn't happen again.
Glad you got it sorted, lg sent me an email saying they are sending me the phone back, they haven't asked for any money so i assume they've fixed it under warranty
Got it back today, says the phone has had a new battery and flex. Could the damage have been caused by the wireless charger?

i have a tmobile wing. it randomly freezes while using it, fades to white then off, turns off
sometimes only way for it to come back on i have to take out battery and put it back.
when i turn it on sometimes itll loop the tmobile thing, maybe make it to the windows mobile green page then turn off and try again.
ive reinstalled the tmobile rom, installed open touch, still the same thing.
i read about the memory card having a loop porblem so i took it out, still. tried installing total commander and renaming the file but it wont let me rename it.
thought the screen ribbon or another wasnt in good so i took it part and made sure i put everything in good.
maybe the fact that a pin that touches the battery it broken? see how they make an arc or so. and the 1 is broken. is that the problem maybe?

That may well be the case. The first thing to try is to plug the phone to the charger and see if the phone works properly. If it does the next thing would be to get a new battery.
I had the same problem and it was solved by installing a new battery.
Best of Luck
yes it does do it while plugged into charger. a little less though.
and ive noticed that when i try to fix the back cover, doesnt fit right so it pops off on 1 corner, i take it off and put it back on tight, from me pressing down the phone likes to freeze and reboot.
ive been thinking about a new battery. i guess ill go ahead and get one then.
Hello,
I've had my hd2 for about 6 months now and about a month ago it started randomly crashing. I'd have to take the battery out and reset, but when i'd start about 1 out of ever 4 times it would show the inital launch screen, but the numbers in the bottom left would never come. So i'd have to remove the battery again and reboot.
Then it started happening more frequently. Random restarts, crashes, and the phone didnt like to boot at all most of the time.
Last night, it gets really bad and i am able to get into the phone once. After that it freezes always when you initially power on, you see the boot splash, but no numbers in the bottom left, no moving forward.
AND NOW when i power on, the screen stays black, and it just vibrates and will not stop at all unless i remove battery. In fact, as soon as i pop the battery in, it starts doing this.
WTF!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Try doing a HARD RESET.
If that does not help it means you have a damaged HD2 motherboard, try contacting T-Mobile or HTC for a replacement.
I'm 100% sure it is a heat problem. I do have the same problem. With my HD2 disassembled I checked that "freezing" the motherboard make my phone boot without a problem... and it worked properly as long as it stayed cool.
I'm trying to replace the motherboard by myself as I do not live within the USA...
Hope it helps.
Same exact problem here, although it happens less often for me. How do we keep the motherboard "cool" so it won't happen? or is this a sign of motherboard going bad soon and it'll be replaced sooner or later??
I think it is a sign of a dying phone... or at least a dying motherboard.
Maybe (just a theory) these are signs of a "cold joint" similar to what happens to the Xbox 360... and the way to fix it is to "reflow" the motherboard... but we need a more technical point of view on this one...
Thanks for the replies. I have tried the hard reset, but it just vibrates with the screen off still, no success in any attempts to do anything. I guess i will have to contact htc since i did not purchase the phone from tmobile.
I did notice before this happened that the phone was getting hot after even a few minutes of use. So i have to assume it is a damaged motherboard or whatever it is inside of my precious hd2 that makes it bring me joy.
Now i am joyless and sad.
Back to the old 2g iphone
*cries*
Im having the same problem too,its not even 3 months yet since i got my phone.can i still have tmo replace my phone?istill need to flash it back to the original shipped ROM.right now ive been flashing it with diff custom roms and still having the reboot issue.
Sent from my HTC Windroid using XDA App
Hi Guys, I need help, I cant boot my device, the blue led always on and cannot turn off the device.
I tried to look over the forum but I found nothing similar to my case.
first. I always have random freeze and rebooting, none of custom roms helps, then I try several kernels, none of it worked. I booted in safe mode, still the same. and I flash stock several times but still the same.
and yesterday, it turned off, wont booted or turned on at all, even button wont work, when I connected to charger, it wont show led, I guess my battery is the problem. then I shake my phone gently, finally it booted.
and this morning, it suddenly turn of to boot screen, I cant event enter recovery or download mode. try force restart several times but then it show s7edge boot screen then show the black scrren and red writing. now I cannot turn it off.
I tried to connect to smart switch, it recognized my device but stated that my device is not supported for initializing.
I cannot even connect it to charger.
Anybody please help me, before I take it back to service centre.
thanks in advance

hi there, exactly, I never saw something like this before. I couldn't turn off. so I just leave it in cool room (16 degree celcius, air conditioned room) to prevent it over heating and explode ( lol I was scared lol)
and it just turn off, and I tried to enter download mode again, it worked, but lol when restarting it stuck and bootloop again (freeze at bootloop).
I guess I need to take it for service though, I am pretty much sure it has something to do with hardware
That's the Bootloader Exception BUG. Not really a bug, but defect. This error is shown when there are bad blocks on the flash nand chip. Some users had luck continuously trying to reboot to download mode. Others didn't. Either way it is a hardware defect. You better give it to service.

wow thanks a lot!!! I thought so, It must be hardware related issue. I will bring it to service center tomorrow.
appreciate a lot ^^
Hello everyone!
Well... the story of my Nexus 4:
I have my Nexus since June 23, 2013. In 2016 it started acting up... It randomly shuts down(It will not reboot, only shut down). Power button needs to be pressed hard to power up(to lock-unlock as well)... so I have decided to change the battery. Bought one from a trusted website(they claim is original) for 17,95€. Replaced it. From my tests it was worse than the original. Phone still randomly shuts down , battery % spiking... it would randomly drop 5-10-15% (same for charging). Then I rooted the Nexus and installed a custom rom - Nitrogen-OS-mako-20161230(it will still randomly shut down but not that often). After just 1 month the battery swelled up. Replaced it within the guarantee. Same thing happened after about 3 months to the second battery. I searched on the internet for fixes but no luck... I disassembled the phone again and I installed the original battery that came with the phone and replaced the usb port(maybe this would fix it?)(no it didnt... but it fixed something tho... the power button works smooth again.. dont have to press it hard anymore.. whaaat?), flashed back the original rom 5.1, no root only unlocked bootloader. Still getting random shut downs... at this point I have no more options.
3 days ago I rebooted the Nexus into SAFE MODE. Battery is at 40% after almost 3 days! No random shut downs. WHY?
Can someone explain to me why the Nexus is working like the first day in SAFE MODE?
I have to mention that the Nexus had no apps installed... only the stock ones when it shuts down so... eliminate the possibility of an app causing this.
I dont use it as my main phone but I do have a SIM card in it. I only use an app when I go to the toilet which is Twitch and it works fine in safe mode
So what is safe mode? Why safe mode is so kind to the battery?

Nexus just rebooted by itself into normal mode while it was charging... wtf!!!!!!!
Nexus just rebooted by itself after 43-44 hours (100% battery down to 60% in normal mode).
After just 15-20 min Nexus just shut down by itself doing nothing on it.. just found it like this... what can I say... F... LG and F... this phone... Thread can be closed... If you have the same problem as mine has.. dont bother... F... IT!! Go get a new phone.
I'll advice you to go to your official LG repair store for battery replacement, batteries online are not reliable at all.
Ps: Safe mode in android is just your default apps and settings but no 3rd party apps that you have installed so technically its less resource consuming and hence better battery life.
Here is the deal both Google and System UI crashed on my S5e last night while I was reading and now I am unable to reboot/power down the tablet using either the Power button or the onscreen controls. As you can see it is just the 2 onscreen buttons that I get and n othing happens expect they dissapear when I try and tap either. Also I am unable to use ADB in this sitution to force a reboot/power down as can be seen in the second image. At this point I am at a lost on what to do besides wait for the tablet battery to die which in its current state could take days if not a week+ considering that nothing is showing up.

You try a 20+ second long press on the power button (if that's correct for that model) to do a hard reboot?
Yes I have I have held the button for a bloody minute aka 60 seconds and no reboot/poweroff

The only other thing you can do is physically disconnect the battery or wait for it to discharge.
If you get it to reboot go into safe mode and backup all critical data. Then factory reset.
If that fails it will need reflashed or the hardware issue causing it fixed.
That is what I thought and as I said it can take up to a week+ for this to discharge since it was nearly full when it happened
If you used a SD card as a data drive and it's not encrypted at least the data can be salvaged.
It may not be as bad as it looks but I'm thinking a mobo failure. I've never seen this type of behavior with any of my Samsung's.
Recertified ones can be had for $200 or so but will likely be upgraded to the latest OS version for it. If you're running on Pie you may not like it.
I bought this one for $275 back in 2021 and ended up receiving a used one when Amazon said it was suppose to be new so yeah something like this was bound to happen sooner or later

I would've returned it. I use one vendor where I got a new N10+ a little over a year ago. His prices aren't real low but he's trustworthy. Their price is $600 for your model. He buys lots of unsold new devices. There's lots of scamming going on, something I noticed when I was shopping.
Apparently you have to hold power and volume down to force power off a Samsung device so you missed a step there. Also the tablet seems to be working fine now after doing so

Correct. Hard reset is both buttons; something I never have to use. However long pressing just the power should force it to shut down.
Try clearing the system cache from the recovery menu.
