[q] urgent! Nexus 4 won't turn on!

I have had a nexus 4 for a while, and I rooted it about 2-3 months ago, but today for absolutely no reason, it won't turn on (please note it was fully charged when I left it). I have tried to leave it plugged in for a while, and after I tried turning it on nothing happened. When I connected it to my computer it showed up as QHSUB_DLOAD. I don't have any custom rom or kernel, all I have is an unlocked bootloade on my rooted nexus 4. I tried holding the power button for over 30 seconds (it was suggested on another post here at XDA) and it still wouldn't do anything. Please help me, I have no idea what happened or how to fix this.

PROBLEM FIXED!
jonapunk sent me a message with a simple procedure to solve this:
"Try volume up and power for 20 sec. Then press power button one more time"
I have put his message up for everyone to see in case they encounter the same issue.

There are several threads already dealing with this.

Got a new replacement Nexus 4 from google today and turned on phone and the colours were all fuzzy. After turning screen off, it doesnt turn on. Doesnt go into bootloader mode. Tried all the button combinations also.

[Q] Galaxy S4 died after 4.3 update

heya guys,
I'm on stock FW on my GS4S i9505 and yesterday morning i update to 4.3 OTA.
It was working all day just fine without issues or lag for the matter.
Today morning when i woke up, my phone was plugged into the charger and was turned off.
I turned it on by couple of mins later it would freeze and wont unlock, just black screen with a red light flashing on the top left of the phone.
I had to pull out the battery and put it back everytime i wanted to try and boot it.
I did that 3 times within 10mins and the 4th time it just stopped turning on all together.
Anyone has this issue and maybe can give tips on how to fix this if possible?
Thanks in advance.

You will need to go to SamMobile.com and download the official odin flash firmware
for your phone's exact model and flash it using Odin.
That will get the phone into good working condition with the stock 4.2 firmware.
After that you can use the phones built-in updating system again and most likely it
will work just fine. Just be sure that the battery is at least half full before the phone
starts the auto-update process.
Perhaps you installed some app or game from the playstore which did not play nice
with your phone and caused the 4.3 update to get stuck or it could have been the
battery if it did not have enough charge in it.
You should try to get the phone into download mode to see if it can be Odin flashed.
Hold the volume down key at the same time while holding the the power key down
for 20-30 seconds and see if it goes into download mode.
If it does you have nothing to worry about.
NOTE: before trying download mode be sure to remove the battery for 5 seconds
and replace it, making sure the phone is in a power off state before trying to boot
it into download mode.

Thanks for the reply dude.
I'd love to do that, but i dont see how this is possible since the phone doesnt boot up at all anymore.
Any ideas?

Maybe your battery is dead? Because it's known issue on Galaxy S4 phones.

Try another charger.

I tried with my wife's S4 battery and my colleague's S4 battery.
Also tried with 3 different charges that came with the S4, no dice... :/
I had to take it back to the store, it was under warranty still.. they are sending it back to Samsung and will get it back in 2-3 weeks, same phone repaired or a refurb i guess.
After doing more search and with the help of some falks from #Android @ EFNET, we came to the conclusion that its an issue with the EMMC chip just like the first generation of Note 2 and S3.
What's pissing me off is that Samsung fixed the issue on Note 2 with a new patch of phones, so newer phones didnt have the EMMC issue as far as i can tell. SO why the hell would they still use it for the S4 is beyond me.
Just a word of advice, if this happens to anyone, make sure you run a backup as soon as it boots back up the first time.
In my case, it booted 3 times by removing the battery and putting it back and froze 3 times, there was no 4th.
If i tried to backup the phone the first or second time it booted, i could still have my data to be restored on the new repaired phone.
This should be marked as closed unless some other people with the same issue want to discuss it here.

It could be the battery itself. They do go bad. Check it to see if it has any bulging.

Freezing! Rebooting?

Hey guys
My edge has frozen 3 times already to the point I have to reboot holding the 3 buttons.
Anyone else have this issue?

My screen went black, had to hold the volume down and power until it rebooted. I've only had this phone for 4 hours.

Nope guys, mine running like a dream and I'm Def a power user. I'd try a couple back to back factory resets.if you still have issues, take it back.

Got the same issue. And factory reseting didn't do anything. I also tried to reset using the 3 buttons but it just says downloading for more than an hour! I really don't want to send it back and go trough the whole hassle. I just want a fix. I got this phone yesterday and I can't enjoy it... it only freezes when on standby for some time. The only way I can get it to work is by using the 3 buttons just like they guy above...

The downloading screen is just a bootloader screen for flashing rom while odin. If you isn't flashing rom, you don't need to wait for it since the phone is doing nothing.

Got a reboot once on PAW FW. Nothing after.

Yep had one yesterday after using bbc iplayer, tried to go back into iplayer from multitasking and it froze then went black . .used the volume and power for 7 secs and everything came back on . .
Hoping this is just software. .
Mine is UK version and got it on the 8th . .
Read that the S6 had similar problems

Anyone have a fix for this or do I need to take it back to Verizon? I'm in the US and have the same issue. It has happened to me multiple times.
I get automatic reboots as well as full screen lockup for 7-10 minutes where it reboots itself. Both seem to occur when I'm trying to do something immediately after doing something else. Examples are when I hit send on a text/tweet and then pull down the task bar while it's in the process of sending the text/tweet or when rotating screen to look at a picture in landscape mode in Facebook and immediately tapping the center of the screen to get rid of the text on the screen.
This has now happened every day I've had the phone (Friday, Saturday, and now Sunday). It's getting quite old. Any help would be appreciated before I take my phone back to Verizon tomorrow.

I haven't had any freezing, but I did have my first random reboot after 4 days of ownership while listening to music with it plugged into an aux cable..

Same.

i experienced the same issue, freezing up, i reset my phone and someone told to me to install an optimizer to help my phone by freezing up

I got the phone for 2 weeks now, yesterday my volume down and power button is unresponsive, press the power button for a few seconds but it wont respond. I have to hold volume and power buttons and press until a few more seconds and ir restarts, after rebooting it works ok.

Anyone have an update to this thread? Has anyone gotten a fix for this? Or should I just send my phone back and get another? Thanks for any help.

Just had another freeze and shutdown . .doesn't reboot but requires me too use power on and volume keys for 7 seconds to restart phone. .really hope its a software problem ..seems to happen on multi tasking

same for Galaxy S6
i have the Galaxy S6 and i have the same probleme, my phone keep freezing and some time rebooting, i try the safe more but still freezing, i delete the new installed app with no luck.
some other wesite say this is an apps crash that make the phone freezing, but i don't know.

Don't worry, Samsung will fix this with an update. Only had 1 reboot and it was on PAW fw.. now that I'm on pb4 it haven't happened once.

I have a verizon S7 edge, and have had multiple reboots on the phone, with no consistent pattern. It has done it while sitting on the bed untouched/unused. It remounts the SD card every time this happens. I'm really stunned there is no word from Samsung about this issue

I have had the same issue. I worked with a Samsung support member who was helpful in attempting to troubleshoot and log the issue. I ran my phone in safe mode for a few hours in hopes that it may have been an app I downloaded causing the freezing issue but unfortunately the phone froze again while in safe mode. According to Samsung, my next step is to go to a Samsung Experience shop in a Best Buy and have them do a software flash. I'm heading there today and if its successful I'll be sure to post about it.

samsung s7 edge freezing
i have a samsung galaxy edge 7 and it just froze on me too the screen froze and non of the buttons worked for the rest either so i popped the sim card n it unfroze.

Hey, this is software problem. Dont take it back phones. Maybe chrome, messenger freeze phone. Just send feedback Samsung. Samsung will fix this with update. Its not phone problem. Easy guys...

S5 SM-G900F : Black screen/Boot loop; Help?

tl;dr at the bottom
Alright so I'm out of ideas on how to fix this phone, couple of days ago my mom came to me complaining that her S5 was giving her trouble. When she handed me the phone, it was in a bootloop of showing the Samsung Galaxy S5 screen, playing the theme and vibrating afterwards then rebooting. I took out the battery and tried to power it on, it ended up successfully booting into android. So from here, I figured there must have been some malware on the device, I downloaded Malwarebytes from the Google Play Store and ran a scan on the device. However in the middle of scanning, the device turned off it's screen and rebooted. (Malwarebytes found 2 malware on the device at that point) So now I'm convinced it's most likely malware and eventually removed all the detected malware on the device. I gave it back to my mom thinking it was fixed.
Moments later she came back saying that it's still giving issues, my first thought "wdf, it was working wasn't it?". I looked at the phone again, and tried to wake up the device using the power button. The 2 soft keys at the bottom lit up however the screen was still black. At this point, the phone was still working fine, the only issue was the screen wouldn't wake up. So I decided to do a battery pull once again to reboot it and it results in the bootloop once again. I did some googling and found various solutions to this, one of them involved wiping the cache from recovery, so it tried it. Booted into recovery and wiped the partition cache (i think that was it), after it wiped and was about to reboot, I noticed a brief "error icon" just before it rebooted. After this point I could not boot into recovery at all (it would just show a black screen and I would assume that the phone turned off) and it was still in a bootloop. It was only after trying to turn on the phone after trying to boot into recovery that the idea of the phone wasn't off and the screen was just black entered my mind. (Because usually if the phone is off, you can turn it on by holding the power button, the phone would not turn on until after a battery pull)
So at this point, it was late at night and I was tired. I left the battery out and just went to bed. The next day I tried to turn it on again and to my surprise it booted up fine but I was skeptical. I had a theory that the device would work fine as long as the screen remained on, so I set the screen timeout to 10 minutes and kept it on for probably 30 minutes while I continued to google. Since it stayed working during that period of time, I thought perhaps locking the device triggers the issue. I turned of "Power Button instantly locks device" and proceeded to turn off the screen using the power button. When I tried to turn it on, it was back to the same problem (black screen, device is working fine, soft keys lit up). I did a battery pull once again in an attempt to reboot and now it was back to problem #2 (boot loop, can't enter recovery). At this point in time, I considered doing a factory reset but since I couldn't enter recovery, I'd most likely have to re-flash the stock firmware.
Since I didn't have much experience flashing android devices (I personally only flashed 2 or 3 devices ever, all of them were successful but I still didn't really trust myself), I had it sent to a local cellphone company and had them try to fix it. Eventually I got the device back, but they were unable to fix the problem (they tried to flash a stock and custom rom). Now I'm back to square 1, the phone is still in a bootloop, no sound, no vibration this time, I don't have much experience with phones since I've only owned 2 in my life. The phone seems to be soft bricked pretty good, I've still got 1 more trick to try (full stock firmware flash) before I call it quits, any ideas?
tl;dr
- device is stuck in a bootloop (issue 1)
- i was able to enter recovery mode once, now it's not accessible
- download mode is accessible
- the device has been able to boot successfully a couple times, but then it has another issue.
- device's screen would not wake up after turning off, softkeys still worked, everything else still worked. (issue 2)
- the device was sent to a local phone repair company to fix (unsuccessful)
- currently device is stuck on issue 1
additional notes
- device has not been dropped or wet
- device has been owned for more than a year without problems
- this problem was recent (3 days)
- no sd card
- dark screen was turned off
theories
- screen could be malfunctioning or defective somehow, but then if it can show the bootscreen and download mode screen fine it seems unlikely also since it's been working fine for over a year
- it's a software issue of some sort, but has already been flashed by local phone repair to no success, then again I'm assuming they just did a basic recovery flash and called it quits
