[Q] Nexus stuck on 'X' screen, even after full wipe

So, a few days ago, I started having some problems with my stock Nexus 7 (not unlocked, no ROMs or anything like that). Some apps just wouldn't open, they would force close within a second of opening. Anyway, I think it might have stemmed from the game "Let's Golf 3", as problems started after playing that, and when going back in to it after a day of issues, a message appeared saying "Unfortunately, launcher has stopped" - it gave me the option to report or cancel, but whatever I pressed, the message popped back up. I pressed the sleep button, which seemed to turn my Nexus off somehow.
Then, when trying to to turn my Nexus back on, it just stays on the 'X' screen. I have done a factory wipe through the fastboot menu a few times, but it still stays stuck on the 'X' screen. To turn it off, I hold down the power button, but it just starts the process again automatically. The only way to actually turn the device off is through the fastboot menu.
I have seen talk of 'factory image' and drivers etc... but I am not too comfortable with that sort of thing. I know the basics of troubleshooting devices, but not much more. I am very wary of doing anything more than what the device provides me with.
Any idea how I can get my Nexus started, or am I going to have to look for a replacement?

If all else fails, then flash stock rom. If you're reluctant to do it the fastboot way, use toolkits. But it is very easy to flash a new stock rom. Go try it.

Is that not for rooted devices?

Flashing the factory image for my N7, how do I know which version my nexus is? i.e. 4.1.2 (JZO54K) or 4.2.1 (JOP40D)?

Use the one you like, just choose the right one for grouper -> nakasi (wifi only) or nakasig (with simcard)
4.2.1 is the latest Android version...

I too had the same problem. Tried everything. Finally gave it to ASUS service centre in Nehru Place. They will replace the mother board. May take 15 more days. So sad!

Okay, now the thing won't even turn on.
Holding the power button, and other combinations, nothing happens. No image comes up when charger is put in.
Feel like the thing is dead. Probably going to have to get it fixed or find a replacement. Don't want to spend too long without my Nexus

FYI,
The tablet can "play possum" when it is in APX mode. (Which is easily entered from a cold start condiition with Vol-Up+Power) By that, I mean the device is on, but absolutely nothing ever appears on the screen. The only way to detect this is to plug it into a computer and the unknown APX device (USB Hardware Id VID_0955&PID_7330 ) will show up.
The only way to exit that mode is to hold the power button down continuously for 15-18 seconds. [size=+1]IF[/size] that happens, pressing the Vol-Down button immediately after the Google logo appears will pop you into Fastboot mode.
But, given that you have prior experience with other odd happenings on the tablet, the above hypothesis is a long shot, I'm more inclined to say "It's dead, Jim".
If everything fails let it sit for 3 hours on the charger (as long as it is not overheating or something) and try a few more things one last time before you ship it out.

Yeah, cheers, I have it on charge now, and i'll give it one last go.
What is the best way to fix/replace it? I bought it from Argos - will they take it back (bought back in December)?

Call Asus first. Make sure to let them know it is less than 2 months old. If they want you to perform the return through the original retailer, they will tell you. But it's best to eliminate any other middlemen if that is possible, as I suppose that the tablet ultimately goes back to Asus anyway.
(Might be different through other channels, e.g. PlayStore - I dont know).

Won't start up help needed

Okay about two weeks ago I updated to 4.4.2 from 4.2.2(I think that's the one?) on my s4 and I've hated the update. I decided to root my phone using muniz method and it worked perfectly. I even changed to the nc1.
So, after using my phone without issues for two weeks roughly I noticed last night it started to randomly turn off while texting. It would just auto restart but it happened every 5-10 minutes. After an hour it started happening more often so I plugged my phone in. Now my phone will not even turn on. When I insert the battery the samsung start screen appears for about a second and then goes black. I have to pull out the battery for the phone to do ANYTHING. If the phone is plugged in while trying this and I insert the battery I literately get NOTHING. No samsung screen or anything.
Things I've tried.
Swapped the battery.
boot into odin
boot into safemode
plugged it in while trying to boot
Swapped the usb cord
taken out sim card
Some things to note is that I did not install any new app before this had happened. It was working the same for about two weeks with no issues.
When plugging in my phone to charge or anything I never get an led light at the top of my phone.
I seriously need some help with this. Any suggestions are appreciated!

Are you plugging it in to the stock wall charger? Your best bet is to get it to boot into download mode long enough to reflash NB1.

Yeah using stock wall charger from a wall, computer, and even a different charger.
Is download mode the one where you hold vol down + power + home?
If so it brings up the screen that asks you to press the volume up but it dies before it can ever make it to the downloading screen...

Experiment and see if you can get it to stay there. If not, you may need to try a best buy if you can.

Thanks, i'll keep playing with it but so far it just shuts off instantly in about a second or two.
If I bring it to best buy and they take it or anywhere else will I be shunned for rooting my phone?

If it won't start they won't know it's rooted. They'll try to flash the firmware which will remove root if they're successful, so again they won't know

That would be fantastic! If I purshased it at walmart would it matter if I take it to best buy for example? I'm sure a corporate AT&T store could do the same correct?

I couldn't do factory reset because the phone wouldn't stay on long enough to do ANYTHING.
So as an update to this...
I was on my way to the closest store with samsung experience which is about an hour away from me and when I almost get there my phone RANDOMLY turns on...
I couldn't be more pissed and happy at the same time. So, obviously I try messing with it a bit and it shuts off again. This time I can get it to turn on after about 15 tries. Long enough for me to do a factory reset!
It lasted a good 30 minutes to an hour and it shut off again.
Hardware issue or is anyone else having this issue with 4.4.2 nc1?

No I haven't on mine you all have to bring it in for repair

Okay so I brought it by best buy and the guys couldn't flash it or do anything to it because it wouldn't turn on at all. They tried several batteries etc.
So, I decided to try the phone doctors and the guy thought it could be a malfunction in the power button because the phone tries to boot up any time you put the battery in. You don't have to hit any buttons and you can't insert the battery without it trying to power on.
I'll cross my fingers that's the problem and they phone doctor guy told me he has never seen this issue with an s4 but it was really common in s3's.
I go back in two hours to see if they have fixed it!

The s2 had this problem too and one way to confirm it was to pull the battery and put it back in. If it booted right away it was the power button. So it sounds like you're on to something.

Well, I was really hoping for the best and I thought they really had my problem figured out. When I got back to the store they told me they basically checked and rewired everything they could and it was still doing this. They told me they can't fix it and didn't charge me anything.
It looks like I have a lemon...

I would but they don't accept anything past a year. If it ever boots up again I'm going to install a different rom and just cross fingers

I've been informed my phone might still be under factory warranty. Just out of speculation, if you root your phone and it ends up malfunctioning what would they do if you send it in for warranty? I'm not sure if my issue is hardware or software related at all.

[Q] Galaxy S4 hardbrick

Hey,
This is my first time posting here and really using the site. I have the Sprint Galaxy S4 and just updated to the SlimKat official build 7 and had no initial problems. A day later it starts to reboot constantly and would stay on for a couple minutes. Now it is stuck in a bootloop and will shut off even when going into download or recovery mode. When plugged into a computer the computer won't even recognize the phone and the phone will not turn on. The only time the phone will even start to boot is when it is not plugged into wall/computer and on battery. I have no idea what to do now.

That's a tough one. Usually with a soft brick, if you can make it to recovery, your phone can be saved but since you can't... I hope you get it working!

Go to sprint galaxy s4 thread. All answers there. You need Odin 3.09 then stock ng2 tar. To flash through computer.
Sent from my SPH-L720 using XDA Free mobile app

I already have odin and the tar files for stock. When plugged into my computer it will not even register that it is connected and so I can't use odin to flash it.

The same thing is happening to me. I get to the Galaxy S4 splash screen, then it shuts off. Even if I try to boot into recovery

I'm going to pile on in here as I seem to be having a similar issue. I had my S4 (not rooted, stock rom) on my dock streaming google music. A phone call came in and the phone started vibrating like crazy and wouldn't stop. The screen shut off and the phone was still vibrating. Finally it stopped and was shut off. When I try to start it a few things happens. It will sometimes boot to my lock screen and the screen goes black and I think it is powered off. Sometimes it will get past the lock screen and then die shortly after. After like 2 or 3 times of that it won't even boot. It loads the Samsung screen but never gets to the Sprint screen or boots. If I leave it for some time shut off with battery out it will go back to booting to the lock screen then dying etc... When I press the buttons to get into recovery it says recovery is loading and then the screen goes black. I swapped batteries and that didn't do anything. I tried pressing the menu button or the home button to try and boot safe mode and it just loads normally not that I think that would help anyway.
Any ideas on things I can try next? What is this odin thing? Would that work for me?
---------- Post added at 07:09 PM ---------- Previous post was at 06:16 PM ----------
Ok... I can get into recovery now and will try a factory reset. Are you sure you are going into recovery correctly. Apparently I was not. Hold volume up power and menu button and when the phone vibrates let go of power only.
Before I do a hard wipe is there any way to get data off the internal memory from recovery mode?

So I got a custom recovery installed, reinstalled stock rom, things worked ok for awhile. Then it started random reboots every 10 mins or so. Now it is back to instant crashing and rebooting. Any idea what could be the issue? I'm assuming at this point it is hardware related. Why can recovery and download mode run consistently without crashing but when an os is fired up it has issues? If it was a hardware issue shouldn't it not work across the board?

So I had Sprint replace my phone on the 8th. I have been using my same batteries (1 stock 1 Anker) and chargers (some stock some not) without issue the past 5 days. I rooted and installed xposed and some modules (original broken phone was never rooted and was completely stock). Things were going great until tonight when it started reboot looping exactly like the old phone. I switched battery and same proble. After I took the battery out and left it out awhile it fired back up but I'm afraid the problem will return. Is it possible that the battery or charger randomly are causing damage to the phone? I only have 14 day warranty on this replacement and need to figure this out.

So things were going well for awhile and then the reboot loops started up again. I did some digging and read that apparently Samsung phones are notorious for sticking power buttons and the symptoms were exactly what I was experiencing. I watched some videos online how to open the phone and clean out the power button but it didn't make a difference. I then read that squeezing the connector for the power button with a pair of pliers sometimes does the trick. Not for me. So finally since I'm not under warranty, have no insurance, and the phone wasn't working anyway, I just ripped the white plastic part of the power button right off. Well, that seemed to do the trick. Phone immediately fired back up without issue and has been going strong. I glued a small thin piece of plastic where the old one used to be and I am back in action. If my little plastic piece solution eventually fails or breaks off I will consider soldering on a new button but so far so good.
If you have tried everything else, and are looking for last resort, try cleaning the power button with some alcohol, and if that fails, rip off that power button! Here is the video that gave me the idea: https://www.youtube.com/watch?v=3Glllc7bEJs and here are some other power button videos: https://www.youtube.com/results?search_query=s4%20power%20button&search_type=&aq=f&oq=

EDIT: Nevermind - Prime Edition Bootlooping right out of the box

EDIT: Total NOOB moment here, the phone doesn't come with the battery installed, it's sitting at the bottom of the box under the documentation. I was thrown off by the fact that the bootloader said battery ok.
Just got the Amazon Prime edition Moto G Play (Model XT1607) in the mail today and it's just in a continual boot loop cycle; the Moto splash screen flashes for a few seconds and then reboots. I'm able to get into the bootloader, but any option I select just reboots the device. I assume it's hardware issue because it only even turns on if I have the charger plugged in (although the bootloader screen does say battery is ok), it shuts off immediately after removing the cord (yes, I've let it sit plugged in for a while). Is there anything I can try without being able to get into recovery? I assume I'm out of luck until they post the factory images for this model?

Hahaha it's okay bro, we've all made some kind of noob mistake at some point.
I once spent four hours trying to root a phone, everything went perfectly, I'd reboot the phone and still not have root. Turns out, I didn't realize my GF plugged her phone into the back of my computer to charge and adb was only picking up her phone instead of mine.

Phone suddenly hard-bricked. No recent flashing.

Hi everybody,
What Happened:
My phone has suddenly become totally unresponsive. I have been using it most of the day, it was sitting at around 70% the time that it happened, but it is now a totally black screen. I had just taken it out of my pocket and it was suddenly like this.
The only idea I could come up with as to why this happened is that I charged it off of a JBL Charge 2 last night. I'm not sure if that may have messed with the battery, but I do find it odd that it's totally unresponsive while plugged in.
I was running android 7.1.1 DP2, with the ElementalX kernel 4.0 I believe. I was also rooted with SuperSU. What's really odd is that I hadn't done anything new recently besides install uTorrent and VLC media player. Otherwise, my routine has not changed one bit. Up to when the phone actually died, I hadn't even used either of these new apps the entire day.
What I've Tried:
I have tried plugging it in via AC, via USB, I've tried booting into recovery or fastboot, but there is zero response from the phone. No indicators on the screen, no LED blinks, no vibrations, nothing.
What I'll Try:
If anyone has any experience with this happening, I could use some advice. Otherwise I'm just going to wait it out, consider an RMA I guess. However, my device did have the bootloader unlocked and was rooted, so.... I hope it comes back by itself.

My advice is to keep it plugged in, or see if there is a response on the computer perhaps on fastboot, upon using the bootloader keys. I haven't had this, just a few suggestions. Good luck!
PS: A RMA will probably be needed, there are much more experienced people around here. Sure you may get replies later.

Good luck?problem all nexus 6p!!! Lg responds repay helps, hawuei what to do? problem arises with nogaut not be our fault, how to fix this? My phone now in service but to be fair this? warranty and having to wait ..
