Nexus 5 eMMC failure. - Nexus 5 Q&A, Help & Troubleshooting

This thread its headed to make clear all the possible causes of flash memory corruption in our nexus 5, maybe some people have knowledge beyond ours, and can help us identify the problem. eMMC revision date, build date could be useful.
And, as the old galaxy s3 with it's sudden death issue (eMMC death), we can have a count on the cases here in XDA forums.
P.D: weather a thread was created before, please a mod could link it to mine.

anyway , so far we dont have a clear cause. Lots of noobs with toolkits , 1 or 2 stock , some heavy rom users . All ages , all batches , all kernels and roms.

There are way too many possible causes for NAND failure. There is no point trying to determine a specific cause as it could be one of many things, and a different cause for different people. The same thread was created a week or two ago.
It could happen while copying a file. It could happen when you turn the screen on. It could happen overnight.

So anyone it's exposed to NAND failure?
I mean.. Is google aware of this? I bet build date is tight related to this problem, maybe its some revision so far.
I tried the app i used to use to check eMMC in Gs3's i9300, search for it in google playstore as "check eMMC brickbug", it will show you if there's something wrong in your nand and tell you revision as well. I know its not for nexus 5, but even recognized the codename 'hammerhead'.

If it happens then it happens. Nothing much you can do to prevent it, nothing much you can do to have it happen on purpose.
There are also no such "revisions" or "build date variations": http://forum.xda-developers.com/goo...lease-stop-talking-hardware-versions-t2597276

Technical or Software problem

Hey,
I have had a vox for over half a year now and I was using the new OS from HTC.
Recently I had to reflash my phone because it was having a number of issues. The enter key on the front keypad would not work. It would handomly turn the bluetooth on. The screen would not be bright while I was using it (the standy dim lighting).
The enter key on the slide out keyboard does work.
After the reflash everything worked great. Now I have used the phone for a week and this starts happening again. Sometimes restarting will get rid of these problems, but it still seems to be there.
I tried to update to Dr. Gonzo's 6.1 ROM, but I was unable to flash that one, I got an error saying the ROM is corrupt.
Do you think this may be a hardware problem?
Please let me know what you think,
Thanks,
GRoder
which ROM are you currently using?
Did you USPL the device before flashing WM6.1 ROM?
that is a necessary step.
Let us know after you flash doc's ROM.

[Q] Galaxy S4 Clone screen not working

Hello,
I've recently bought Galaxy S4 clone and it was working great, till I tried rooting it.
The rooting was through *android kingo root* and everything went flawless. After 15 minutes, I noticed that the screen is black but there's backlight led. I thought it might be out of charge or any silly reason, tried every possible solution but couldn't get any help.
The phone turns on and I can receive calls and reply by guessing the place, I also can hear the unlock/lock sounds. But no luck in turning screen on.
Any help guys ?
this is urgent
Bump.
Sorry but the case is realy urgent. Please enlighten me with any help. /:
This is really important guys /:
Hope anyone can give me a hint ..
Clone
Don't know about a clone but i can think of just two things,
First maybe it's a hardware problem and need to be repaired!
Second if it is caused due to rooting or anything then you can try flashing the official firmware of your device (if available).

Well I think its a hardware problem, because the phone starts up and I can hear sounds.
I could get a screenshot from the phone and see the karnel/baseband ... etc (Attachments)
I don't know where I could find a replacement screen or a rom flashed. Could you assist me with some hints or links?
Thanks.

A screen you should be able to order from china. A rom, now that will be harder to find as clone have almost no support or developers.

Well see thats the issue with clones. No telling what part they used from where.
This is all I could find.
http://forum.xda-developers.com/showthread.php?t=2512243
To be honest it maybe cheaper to replace the device with an authentic version from somewhere like swappa or something.

[Q] Touch+display dead

The display stopped working 2-3 days ago. On booting i can see the google logo for 2-3 seconds before the screen goes dark. The phone works and i can hear dings of messages, but i cant access any of it. Once i kept shut it for a day i was able to see the screen for 10-15 seconds( i used this window to remove the screen lock so that i can use the usb transfer ). Now keeping the phone shut for long duration has no effect.
I can see the fastboot screen but not the recovery screen throught it.
I also bought a slimport so that i could see the screen on my pc. It works (not for the fastboot or recovery), however the touch doesn't work and the volume and power buttons response is too sluggish. I can connect the mouse but it is of no use as i can't see the screen on PC and use the mouse at the same time. I tried adb ( i have no experience of it ) but i cant touch the allow pernmissions key on the screen for the above reasons. Also what advantage would adb be in this case?.
Any advice ?
PS: i have cyanogenmod
I think ram is your only option. It definitely sounds like it's hardware and not software related.

Oh, you mean sending it to LG for servicing? I am a bit hesitant since i have cyanogenmod and also am in india and i doubt they will give a replacement. I think going back to stock rom and then sending it for repairs might help but i have no idea how to go about doing that in this situation.

Its all done via fastboot or lg flash tool. Probably the latter is best for you. Have a read of the guides in my signature

Same issue I had pretty much, it died about 2 months ago. I was still able to copy all of my files, phone worked perfectly but the screen was black. Had it replaced it no time. Is that by any mean a 311k? I've seen another thread like that pop up lately.

I don't know yet, I'm just trying to figure out whether it's a particular batch that started failing or it's completely random, just curious. The two replacements I was sent were 403K. Build is perfect, but they both had some light bleed issues. Looks like every batch comes with some good and some bad, QC definitely hasn't been too great on this phone.

They're not really built in batches. Manufacturing was continuous. They just changed the serial number every time the month changes so I dont think this would actually mean anything
I know but I'd still use it as a milestone more than anything, I mean there have been some differences in the units (eg bigger speaker holes), this way it's easier to track them along the timeline, because they definitely do change something in the manufacturing process from time to time if they have to make up for issues or something. They also did it with the N4 if I remember well.

Speaker holes is a bad example because even the latest built devices it was still a lottery whether you got bigger or smaller holes. That's down to what you mentioned earlier, QC

I was able to unroot and flash the stock image. The problem still exists though, so it has to be a hardware issue. Fortunately the phone is still in warranty.

Nvidia shield tablet Power options help

Heya!
So i just got this Nvidia tablet with blisspop/lollipop or whatever it's called already installed.
Now i've been trying to read through some of the threads on this page but it honestly feels like im reading a different language.
I've noticed the Nvidia power options is gone from the tablet and since im lagging pretty bad often when playing games although not all the time, i'd like to fix this.
I thought the best option would be to increase my cpu usage, do you guys have any guides or tips for me on how i could do that?
Thanks in advance!
honestly, the kernel included in blisspop is plagued with odd behavior.. hangs, audio skips, and weird lag that comes and goes without reason...
some say it works fine for them, but myself and many others have had this issue... so, that is probably your problem.

I understand, is there anything i can install which works better? or am i stuck with the current "kernel" as it's called?
Sorry, i'm not familiar with the contents of blisspop and such.
you can try the official firmware, but if you bought the tablet with blisspop installed on it already... it is probably killswitched... so you need to follow the instructions here or risk breaking your tablet for good.

One last question; if i just use it regularly as i've been doing, will it actually just not work after some time?
Edit: i checked my serial number and it said "Next OTA: ST - yy (urgent)" so im guessing it's killswitched

I assumed the Killswitch is something that deactivates my tablet if i dont do anything to fix it, hence why i asked if it wouldn't work after a while if i didn't do anything about it.
I'll try to follow what the thread says. Thanks for the replies!
the killswitch could kill your tablet the instant it connects to the internet.
make sure you remove it BEFORE you do and you won't have any issues from that point on with anything.

I updated about 4 hours ago, with a device that has never been reseted, and been through 3 major updates (+500 mb) without a reset. No negative consequences have happened at any of the updates, UI is smoother all around, and standby battery has improved a lot. Even though I have both, WhatsApp and Kik open in the background, the battery has decreased only 4% in the past two and a half hours with me using the phone once a while. This is incredible, and the device has not heated up once in use, I can't even tell that the phone is on by feel, because it doesn't produce any heat.
I did read that many people did have issues with the update in India, where it was released first, but I have not had any issues, only big improvements. I've also noticed that the India update changelog did not list the things that mine did, so maybe they did changes to the update? I've also been trying to "use my phone like it's meant to be used", this includes no accessibility service hacks or gutting TouchWiz from the inside with a package disabler. I feel like changing how the system is meant to work is only going to make it worse, since a LOT of people were involved in making the S8 run fast and smooth, the exact way it's meant to be used for the average customer. The user interfering in this by disabling packages will inevitably cause errors in cross-process communication, where system applications are trying to communicate with other system applications that have been disabled by the user.

Odin has nothing to do with the updates received through OTA.
Then the word "Odin" should be removed from the thread title because is misleading

Well, I had the update and can confirm my SD card is now much faster. I store my music and photos on it and now it's just as fast as reading from internal memory. I can't​ judge the Bluetooth part, don't use it much. I have my iPhone for that. I will test my memory speed but expect no issues.

I don't know if any of you have had the SD card mounting/unmounting problem, but do you think or does it fix that issue that has been ongoing in some of the Samsung community? I think it should fix it since it does seem to tweak it considerably. This is what myself and others are waiting for (in U.S). Please leave your carrier or country when you get the update, thank you!
