[q] nexus 5 bricked in first 4 days sos - Nexus 5 Q&A, Help & Troubleshooting

Alright i got 6 hours before tmbobile store opens and i can HOPEFULLY get an exchange, but not banking on it. btw im new to rooting so i wasnt familiar with the process, but regardless i have hard bricked my NEXUS 5. Title says the problem. I followed wwjoshdew's guide to rooting on youtube, and rooted successfully. But i could'nt for the life of me figure out how to create nandroid. I ended up realizing i didnt download cmw recovery mode and downloaded it from the play store. the app took me to a button that said flash recovery and i hit it and my phone asked for permission from unknown source, i hit ok and it shut down, on 70% battery life. Not turning on please help

Try to boot the phone into bootloader mode. Just hold volume down and the power button. From there try to cycle to recovery. You use your volume down to cycle through the options and power but as select. If you can boot into recovery and have that successfully installed then you can erase your phone and try to power it on from there. If you didn't successful install the custom recovery then you'll have the standard Android recovery. You can erase everything from that too.
These phones are hard to brick and not be able to fix it.

Doesn't turn on dude. No matter what. I am new to roms but i know what a hard brick is.

You should really read the guides and stickied threads at the top of these forums. The guides are very noob friendly and you wouldn't have bricked your phone. There's one to reset your device to stock as well. There's really no need for this thread and on top of that there is a sticky that says no questions in the General forums.

Determine your phone is actually off. Plug your phone into charge, if a battery sign appears in the middle of the screen then your phone is off.
If your phone is off, hold down the volume down button with the power button to start the bootloader, press volume down twice and press the power button to enter recovery.
If your screen remains black and doesn't show a battery logo, hold the volume up, volume down and power buttons at the same time for a minute, then let go and hold down the power button. Which should hopefully start your phone.

You bricked a Nexus?
Hold down Volume Down, Up, and Power to get into fastboot mode. Restore from Factory Image.
Normally, to root a nexus, I fastboot Team Win Recovery Project.
Anyways what you did simply could not HARD BRICK the phone.

My Nexus5 doesn't flash the Led light or enter bootloader and software . I was flashing the based CM kernel and i followed the instructions nicely, while using TWRP Recovery i pressed reboot system after the flash and the phone suddenly died. I connected it to the PC and the installing drivers popup appeared and it didn't install them, problem(QHSUSB_BULK) it only appeared once. And since that, phone is dead. PLEASE HELP!!!!

Do you have a link to the kernel you flashed? I think you done bricked it good.

Were you using this method?

If yes,I think then all Nexus 5 users should be warned about CF's autoroot issues,because I see more and more topics related to this issue.

I don't believe the issues you're seeing, appears to be failed emmc, is related to chain fire's auto root. Cf is probably the most popular method to root and it's a coincidence. I've seen these failures with other root methods too.
I think the op flashed a kernel not for his device.

I am not a developer so bear with me. I'm just a guy in mpls with a completely stock N5 from Google Play that encountered similar issue as the original post. There was no damage or water issue, or other problem prior to going dead. It had about 50% battery and maybe 15 minutes after reading an email it was dead when I looked at it again. It just simply turned off while in my pocket. I could not get it to power on or enter bootloader or a recovery screen. After a week of trying to charge via USB and the original wall charger and countless attempts to hold power and volume buttons without success, I decided to pop the back off and disconnected the battery. I put it back together, but that made no difference either. Google play will send me a new phone, but I'd like to get it fired up and extract the last week or so of pics. Any ideas? Again, I am a complete noob and this 3 month old phone has not been modified in any way, other than auto updates from Google play. Thanks for any assistance or guidance.

Thanks - was just hoping it was not a hardware failure given the posts about difficulty bricking N5. Any chance if I bought a new battery that came charged it would fire up or replacing the motherboard an option?
p.s. I am not the original poster so not sure if I ticked someone off or not, sorry if I did. Just looking for assistance

It sure sounds like a hardware failure. Doubt a different battery would help. And don't worry about being the original op. This thread is old

I get the unknown device driver when hooked up USB to computer (QHSUSB_BULK). Think it is worth waiting a few weeks prior to returning it to see if there is a way to access the flash memory via a driver download? Searches for help showed similar unknown driver problem workable on samsung and HTC last year (QHSUSB_DLOAD)

No, you won't be able to. The memory doesn't mount like a sd card would. For the future use something like drop box or Google drive too backup your photos as you take them.

Never mind my last post, you need to be able to boot into a rom to use kdz updater, it's been a while since I had to do this kind of thing.
I'm pretty sure you only soft bricked your phone (i.e. it still turns on) and the only way, that I know of, is to use nvflash. I've had the same problem before, there could be many things that are causing the phone to not be recognized by your computer. Follow this guide http://forum.xda-developers.com/showthread.php?p=17258229
when you plug the usb into your phone make sure the audio on you computer is loud enough for you to hear that "usb recognized" sound. If you don't hear it, or it does not get recognized, try using a different usb port on your computer, believe me that actually worked for me a couple of times. Also, make sure you follow the steps very carefully because if you use the wrong button combination, or release the buttons too early, it won't work.
I wish I could help you more, but that's all i've got.
Good luck, and if by any chance you get it fixed, don't try to root your phone using any root tools, simply nvflash cwm recovery and flash your choice of a custom rom, that will automatically give you root privileges.

every time i look at my apx driver it always tells me to troubleshoot but it always says driver not installed. ive downloaded the same driver in different posts just to make sure but nothing helps. Wireless shops are useless. I live in vegas and there isnt a single store with a person smart enough to figure it out.lol. ive given my phone up for days at a time to shops who brag about "WE CAN FIX ANYTHING" they lied. well i guess im going to search for a few more hours on here to get some kind of lead. thanks for the help. if you kknow anything else or figure something out i would appreciate the help.
Have you tried this stuff?
http://forum.xda-developers.com/showthread.php?t=1619932
It sounds to me like your pc's jacked up the driver somehow. Try plugging in the phone with the battery out and holding all 3 buttons, go into your device manager and uninstall all the USB drivers. Then reboot and try following the apx driver installation procedure again.
Sorry if you tried all this stuff a million times already.
I would say the two things that I would focus on would be to first fix the drivers on your computer. I downloaded mine from the LG website. Next is to flash CWM Recovery so you can flash a rooted ROM to your phone. I would go back to the thread where you got the instructions to start flashing and ask the same questions but only after reading the whole thread. There the orig. developer might chime in and you'll have more specific answers focused on your specific issue.
It's true your phone isn't bricked and have patience and you'll get it fixed.

well i have all the drivers needed. and the computer is fine but the phone is not. i mean the pc doesnt quite read the phone right. with that being said i dont know how to flash cwm recovery to a phone my computer cant read. im running windows 7 64bit and all my usb drivers work fine.
CWM = Clockworkmod Recovery (everyone remember this is a newbie).
Important question: Did you do a backup before making any changes to your phone?
Also, try this: remove your phone's battery for 30 seconds. Put the battery back in. Press and hold the volume down button, then press and hold the power button. Hold both buttons. First you'll see the white LG screen, then wait, when you next see the blue LG screen wait ONE second (no longer) then release the buttons. Tell us what the phone does then and what the screen says.
Have you tried taking out your SIM card and micro SD card?
Usually right after I take them out and plug in my phone while holding volume up and volume down... it usually works after that.
Yup, that's my problem. No matter how many USB ports I tried it still wouldn't read it until I took out the SIM card and micro SD ;p.
Try this on for size...

Sounds like you are having the same the issues i was having with my phone why dont you try this..... First you have to flash a custom recovery image for your phone, follow all the procedures exactly then once you have flashed your CWM Recovery ( i. e. Clockworkmod recovery) Once you have installed that properly, you can now flash your new custom ROM and that should help to fully reboot your phone back to recovery for you to start using again....... hope that works for you.......just as it did for me have a good one!!... :fingers-crossed:

@op can you give us screenshots of:
A: what your device manager looks like when you plug your phone in not in apx mode.
And
B: When it is in apx mode.
To do this: right click on my computer>properties>on left hand side, click on device manager. Hit print screen, open paint and tell it to paste. Save and upload here.

well i brought it to two shops and were both unsuccessful. wireless toyz and smart fix. i have it back and it goes to the lg screen. and instead of the second it flashes from black to a very dim gray back and forth. when i hold the power button along with the volume down it does a master reset and i can press the home button then it takes me to a screen to delete cache partition and what not and you move up and down with the volume keys but i cannot select anything. i think i really messed my phone up.
Somehow you got stock recovery. Google for howbto do a master reset, on devices like the nexus tablet at my work there's a series of steps needed to do a full reset/restore. Just booting into stock recovery may not give you the option. As well, please post those screen shots as I said earlier, this way the issue with the USB can be troubleshot and maybe we can get you a fully working phone with CWM.

ALL questions in General Section.
To answer you.. try wiping data & cache in CWM.
If you don't have CWM, then you did do something wrong cause you needed to have that prior to rooting.

[Q] Help: BRICK'd. can't boot into anything (recovery, download, etc)

background: rooted and was running 4.1 stock and CWM 10.0 on verizon gs3. i wanted to bump up to jelly bean 4.2 with CWM 10.1.
first i tried using Rom Manager and Rom Toolkit to flash a new rom. from Rom Manager, i rebooted into recovery and got stuck on the CWM boot screen.
After 30 minutes or so i pulled the battery and tried flashing the stock .tar.md5 using Odin and ended up with this:
"System software not authorized by verizon wireless has been found on your phone. Please turn off your phone and go to the nearest verizon wireless store for help."
now i can't boot into download or recovery. i just have this screen with the yellow exclamation point and the above message.
how screwed am i? i've tried reading everywhere and from what i can gather i didn't wipe my cache sufficiently, but all the other threads just say 'use Odin to get back to stock', but i can't get into download mode so i can't use odin.
please help.
You're bootloader wasn't unlocked. Pull the battery then hold power, volume down, and home for fifteen or twenty seconds until it boots into download mode. Odin flash a stock rom then root AND ALSO unlock your bootloader.

Ha, I agree although I think its occurred in decreasing fashion since August. Being "bricked" is used overeagerly by folks not wholly understanding their situation. You really have to try to brick this device before that word can be used correctly.
Your phone has not been bricked. You will know that you have bricked your phone when you can't turn on your phone at all. No download mode and no recovery mode also no pulling of the battery just a dead phone.
ClockworkMod
When you fix your phone, root then unlock the bootloader... You can try RM again but I believe that it is best to use ClockworkMod (or the Touch version) for flashing instead of ROM Manager - old fashion, maybe, but it works!
NOTE: Once you start flashing it becomes addictive - you have been warned
thanks for the comments. my apologies for using the term Brick incorrectly as it seems to really chap the cheeks of some people on this board (http://forum.xda-developers.com/showthread.php?t=2149210)
no luck with holding down buttons with the battery pulled. i ordered a USB Jig to try and force it back into download mode.
From there, what should my first step be? return to stock?

thanks that's a very helpful thread. However, i still can't get into download/Odin mode. i'm guessing if/once the USB jig can force the phone into download mode, this is where i'll start.

[Q] Random rebooting does not stop

Hi
This is a well known issue with the nexus 5. My device permanently starts rebooting. The google Logo occurs and then it rebotos again. There is no start animation. If I press the power and volume down bottom I just see the bootloader screen and after half a second it reboots. I can't do anything.
My phone is rooted (no custom ROM) and before I go back to the shop I want to unroot it. However, with this behaviour I'm not able to do it, or is there any chance? Does someone know at least, how I can boot normaly to unroot it.
thanks for your help

Hello, take a look at this thread http://forum.xda-developers.com/showthread.php?t=2513701
Is this really a well known issue? What were you doing directly beforehand? What have you tried to do to fix it? Have you tried using fastboot commands to reload factory images? Are you a toolkit only user? Have you tried a factory image through that?

Well IMHO it is a well known issue (see for example the wikipedia page or just have a look in tech forums). Directly before, I was writing an SMS and put it in my pocket (everything seems fine at that moment). 10 minutes later I just want to check my SMS and then it was already rebooting all the time. This was not the first time, I had this issue 2 todays before, but after approximatley 20 reboots it started correctly.
So far I was not able to use fastboot commands, since I can't enter fastboot. I didn't use a toolkit.

Thanks for the link. I will check it later, 'cause I have to leave. I will write again and let you know if I'm able to enter fastboot.

no problemi, i hope you can unbrick it!
Use this thread:
http://forum.xda-developers.com/showthread.php?t=2513701
Or you can use this toolkit (some people are not fans of these but I am):
http://forum.xda-developers.com/showthread.php?t=2525026
I have never heard of the issue where it was only rooted and it just randomly decides to reboot and keeps doing it for no reason at all without the user flashing something that it did not like. So are you saying that you cannot even turn the phone off it just keeps going into a bootloop and trying to enter fastboot does nothing?
I don't think this is a really well known issue.. Have not seen to many support threads about this.

If the wall charger is plugged into the phone, the nexus just starts rebooting. I see the white Google logo and after one or two seconds it reboots. Sometimes you see the boot animation (4 circles) but after a short time it restarts the phone not able get to the point where you unlock the SIM. Trying to get into fastboot mode is also not possible. The fastboot mode appears but after half a second the phone reboots again. If the nexus is not connected to a charger it repeats rebooting for about four times after that just a black screen appears. If I'm not able to get into fastboot mode I can't unroot the phone, right? So the links you shared are not useful in my case
I have the nexus now over a week and the phone worked perfectly fine the first week.
I have uploaded two films of the problem to youtube, see this link. One film is with the nexus plugged into the chrager and one where it isn't.
That is very strange.
I would definitely use Madpiercing's post and link to http://forum.xda-developers.com/showthread.php?t=2521691&page=3 to try and fix it.

I tried the method described in your link without success. Still the same behavior. See my last post, there I add a youtube-link where you can see what exactly happens.
Saw your video that is very strange

The very strange thing is, that it worked well over a week. the random rebooting starts two days ago, first time it starts again correctly after 5 min. Now it seems to hang in a loop.

After a while I was able to get into the fastboot mode: I plugged my nexus into the wall charger for about 1 hour. Then it booted correctly. I had plugged my nexus into the charger before (over night) without leading to the same result. It seems that it just starts working correctly as random as it crashes
Do you think it is a bug in the bootloader or that something happened while to rooting the phone?

It's most likely a hardware issue, bad cache memory on the cpu. I'd rma it.

I set it up again and give it another try. If something similar should happen again, I will rma it.

make sure you unroot and relock the bootloader and do this now while it is working.

Nexus 5 won't boot, no charging icon, nothing

So I was posting about this in the Purity thread already, but this has become a major unresolvable issue so far..
I just updated clean install/flash of Purity ROM to the newest version, with the included stock kernel.
I tried out xposed framework, and only 1 mod (Serajr Blurred System UI)
on dalvik of course.. working fine for over a day.
Suddenly today, phone turned off in the gym randomly and wouldn't boot, then after 30 minutes in the gym after repeatedly trying it eventually boot, then right when I got home, I decided to un-install the mod on xposed framework, and reboot and then boom, off again not turning on for several hours... phone is not detectable by adb or fastboot. when connected to a PC, absolutely nothing, completely dead..
when connected to pc... the only thing that happens when I do vol up + vol down + power is that it cycles through usb device connecting on the PC but (device cannot start).
I've tried charging it, leaving it, I've went through every trouble shooting option that I know of.
There's not even a way I can communicate with the phone from the PC.
any suggestions, any ideas??
I can't believe that a device would be bricked from xposed module??
I could do an RMA, as the device is relatively new,
but If I return this device I'm worried about warranty void due to unlocked bootloader and custom ROM etc??
I'm leaning towards this being a hardware issue. If you got the phone straight from Google, the unlocked bootloader and custom whatever shouldn't be an issue.

Ok I'm going to try holding vol-up and insert USB, but i assume for nexus root toolkit to work it phone would need to be visible as a "fastboot" device bare minimum, which I'm having problems even getting that right now.

hi, nexus toolkit has an op for soft-bricked/bootloop. it might detect your device.

vol-up and power while connecting usb didn't do anything so far. I'm going to try nexus toolkit just for the hell of it, but I think this device is literally bricked beyond repair.

All bricks are hard bricks. As much as people use the term "soft bricked", believe me - it isn't a thing. A brick is irreparable. If it was repairable, it isn't a brick.
If it is irreparable, its because its been affected beyond the software layer. Messing up the NAND partitions or NAND death are the most common. This can happen during a flash or even seemingly random - its not unusual for bricks to be random. Flash memory in my opinion, is still pretty unstable. Send it for repair /RMA.
