Crushed the back of my Nexus 4, looking for troubleshooting assistance - Nexus 4 Q&A, Help & Troubleshooting

Hi,
I accidentally crushed my photo between a seat and a table on a train. (htp://imgur.com/Q1RUsEk) This is what it looks like after it was crushed.
Immediately after it was crushed, I noticed the phone network icon was empty. I turned off the phone and it has not been possible to boot back into the home screen since then.
I attached the phone to my computer and used ADB to get (htp://pastebin.com/H85Xq2U4) the last_kmsg, (htp://pastebin.com/NArZYWSZ) logcatouput, and (htp://pastebin.de/124812) bugreport output.
I'm not an expert at debugging problems with phone hardware but it looks like there is a problem with the audio subsystem in logcatoutput.
Are there any reasonable steps I can take in trying to resurrect my phone?

According to your log description it would seem that there is physical damage to the system board. The only option would be to do an inspection of the phone. This will require dis-assembly and that does need some skill, although there are several threads here on XDA that might help.
Determining the actual board damage would require some knowledge of electronics.
I would suggest that you look into replacing the unit. With the Nexus 4 you might be able to find a used unit on ebay or on the Swappa forum here on XDA.
Your sign-on doesn't indicate a location, so you may or may not be able to access/use these sites. At any rate you are looking at some pricey repairs, if such repairs are even possible.
good luck.

mini ubs port has gone a bit awol

i need help!
first off i am the most untechnical peron ever so rather sucky at all this, second i can't afford the excessive repair charges and thirdly i hsve an o2 Xda Mini.
basicly the ubs port socket thingie has gone completely wonky and turned it's self around within the phone. i have searched about the place and i can't find anything that i can understand or helps fix the problem.
basicly is there anyway i can open the phone up myself (i've had a look at the phone and there's no obvious way to get it apart) and put the little socket back into place..because it has gone completely wonky. i think it happened after i dropped the phone on the floor (by accident) and now it won't work with the charger.
any help would be brilliant.
thank you

If it is turned around within the phone you most likely broke the contacts with the mainboard, you are pretty much S.O.L. However I think Isaw earlier that some forum member can do it. I'd check into that.
Yea - it is probably broken off the main board, but you can open it up and see what is going on if you are inclined to do so.
Service Manual
You will find detailed instructions and pictures on how to open the phone up. The only difference I think in the manual and this phone is the manual does not mention a screw on the main board. When it talks about removing the main board and getting at the rigid-flex board (page 20), it does not mention anything about a screw in the middle of the main board. It's there - that board isn't going anywhere until it is unscrewed. However, you probably won't need to bother with taking the main board out - you just need to get to where you can see the main board since you just want to see the USB spot.

[Q] Somewhat dead touchscreen?

So my awesome Venue Pro with an already sketchy battery is giving me trouble.
It has only happened lately. I'll turn on the phone from standby in order to, well, use the phone. But 95% of the time, the screen will within a split second go black, showing nothing on it. Funny thing is, every key works and illuminates and you can even interact with the touchscreen as I noticed it made sounds previously when I just started moving my finger along the screen, same with powering it back on when it likes to actually show what's on the screen and it'll be on a totally different app or screen itself.
Because I bought it on eBay, Dell, very ignorantly, is refusing to even deal with me in regards to warranty despite the phone being manufactured this year, so I'm hooped for sending it in at all for repairs.
If the touchscreen technically "works", then what could be the problem?
Thanks for your help, guys.
You might want to google something like "dell ownership transfer." Seems to me there was a way to transfer the original warranty term to another person. If you can get in contact with your ebay seller, he may be able to help you out.
Short of replacement, I say the first thing you should try is opening it up and making sure all the cables are connected internally.

The next step will either be re-flashing the original stock 7.0.7004 rom in hopes that it's a software problem (unlikely if you ask me,) or ordering another DVP off ebay and swapping parts until you have diagnosed the problem.
That's the issue- My eBay dealer didn't actually buy the phone himself. He took them as a donation for his not-for-profit business so the proof of ownership is pretty much MIA.
I'm starting to believe the backlight is failing or something close to that. Possibly due to the slider being used? Not any more often than someone else would use it, though. I looked at the disassembly guide and it's something nearly impossible with my lack of tools or understanding.
I'm pretty much hooped then?
Wow, shady. I bet he took advantage of and offer like this and then just sold the phone for profit.

I can't think of any other ideas personally. Selling it off for parts seems to me like the best course. If you decide to do this, you should wipe your phone with a soft reset as you normally would when selling this phone (in settings > about > more > reset my phone.) If what you're experiencing is a software problem (which, again, I very much doubt) this might fix it. If not, your personal data is gone, and you're ready to sell it.
You may want to let the other forum members weigh in on this, but I don't think there's going to be an easy fix that doesn't involve disassembly.
I have attempted a reset + restore and whatnot, so most likely it would be a disassembly issue then.
The issue with me taking it apart would be that I'd probably do more damage that way lol.

Vivotab RT display problem (vertical Green line)

Hello all,
Sorry for posting here. This is my first Windows device so I don't really know where to turn for help.
All of a sudden there is a 1 pixel wide vertical green line down my screen. What happened? Is there a way to get rid of this? Do I have to send it in somewhere?
Where on the screen is this line? Have you tried restarting the tablet? If you move the mouse onto the line, does the mouse cover it up or does the line go over the pointer?
If it's just a hardware problem (quite possible from the description) you should be able to get a warranty replacement easily. Just set up the new tablet with the same Windows Live account, re-download your apps and mail (you won't be charged again for apps, of course) and you'll be pretty close to where you left off. If you want to be sure all your data is preserved, though, you might want to back it up first (to external storage or to SkyDrive)
Thanks a lot for your reply. I've tried restarting the tablet, and no luck. The line is about 2 inches from the right side. Moving the mouse onto the line, makes the line go over the mouse. Do you think a display driver uninstall/reinstall would help?
If it is a hardware problem, does one just go to ASUS website and find the service phone number and tell them? I just bought it less than a month ago over ebay (Brand New), does it need to be from a normal store? Sorry for all the questions, please just answer whatever you have time for.
Yeah, that's almost guaranteed to be a hardware problem. Given the way the video driver handles the mouse pointer, it's highly likely the pointer would be drawn over the line if was a software glitch. On the other hand, I'd also expect you to be seeing other display corruption and/or video driver crashes in that case. Meanwhile, thesymptom you describe (perfectly vertical line of a single primary color) is actually a common (by the standards of such things) failure mode of LCD screens.
If it was bought brand new, there should have been warranty info included. In any case, I'd suggest getting in touch with Asus, yes. You might need the tablet's serial number or similar, but even if you don't have actual warranty info it should be covered for at least one year unless there's any sign of external physical damage or anything.
Thank you very much for your help. I'll look into the warrantee info.
If the mouse pointer goes under the line, I strongly believe there is a hardware issue. Might not necessarily be the actual display, but could be a cable connection. Either way, it is definitely covered under warranty.
You have one year from the date of purchase, regardless of where it is purchased from. The RMA process usually takes about 14 business days to complete. If you're located in the US and you haven't already called in for an RMA yet, shoot me an e-mail and I'll see if I can set one up for you. I can be reached at [email protected].
If the device is LESS than a month from the reseller, I would actually contact the reseller first to see if you can get a straight-up exchange. I'm not familiar with the particular eBay seller, but most offer a 30 day return period for defective units. Check with them first about an exchange, and if that isn't possible, contact us for a repair.

[Q&A] Tegra Note Discoveries

Q&A for Tegra Note Discoveries
Some developers prefer that questions remain separate from their main development thread to help keep things organized. Placing your question within this thread will increase its chances of being answered by a member of the community or by the developer.
Before posting, please use the forum search and read through the discussion thread for Tegra Note Discoveries. If you can't find an answer, post it here, being sure to give as much information as possible (firmware version, steps to reproduce, logcat if available) so that you can get help.
Thanks for understanding and for helping to keep XDA neat and tidy!
I think I read through this entire thread a couple of days ago, but dont think I saw this little 'Gem' posted here.
I saw somewhere (maybe this thread) the multi-click enabling of some kind of Diagnostics function when
you multiple click on 'Settings/About Tablet/Kernel version', and you get the diagnostics dialog (much
like enabling Developer by clicking on Build number).
The new (at least for me) is multi-click on 'Settings/Android Version', and you get a little easter egg, first time I
did this I got some kind of game (I think, I dont play games), 2nd time, I could not remember what additional
things I did to get into it (there is something after the red screen).
OK, got back into the game screen again but still not sure how, you've gotta click about the screen at random.
Mobile Network setting missing?
My friend just received a Tegra Note P1640 Advent Vega running Android 4.4.2. It's stock, not rooted at all. She wants to hook up her Sierra 313U USB modem so she can get on the net with it, but for some reason Mobile Settings is missing from the SETTINGS app.
I know that this Tablet does not have a SIM card slot, so maybe that's why it's missing. But hopefully there is some way to activate it again without having to root it.
Here is what is listed under Wireless and Networking:
Wifi
Miracast
Bluetooth
Data Usage
MORE
And this is what is under MORE:
Aeroplane Mode
VPN
I found this app in the Google Play store, but that is only a shortcut. So if that Mobile Network setting is not activated, I doubt it will work, or will it?
https://play.google.com/store/apps/details?id=diewland.settings.mobilenetworks&hl=en
What do you suggest? Is there any way we can access the Mobile Network settings so she can use her Sierra USB modem without having to root it?
Tegra Note 7 Hardware Teardown Tutorial
I have been looking on the internet for quite some time now but I have not found a sequence of images or video tutorial on how to disassemble a Tegra Note 7. I only found one post on the XDA forums by member "e8hfff" that said "Tegra Note Openned" but with no images visible. Could someone provide some insight on how to properly disassemble the table?
The reason I am asking is that my TN7 is past warranty and the battery has sadly seen its last days. I have enough knowledge about Lithium Ion (smart and dumb) batteries and the confidence to fix my issue, but I am uncertain how to properly take apart the tablet, not wanting to risk damaging the components. Any advice from someone who has done this would be greatly appreciated. Thanks!

Just as bschles above, I too would like to request info on Advent Vega Tegra Note 7 disassembly.
I've managed to insert my SD Card incorrectly and cannot remove it, it is stuck inside the machine with nothing protruding to get a hold of so I cannot remove it. I would like to remove the casing so as to access the card and extract it, in some other thread someone said they can open casing with just their hands, question is 'HOW' ?
I have tried pulling and pushing and squeezing and twisting, all to no avail. With my eyes, I cannot even see where the joins are and so not sure where I should concentrate the effort to separate the case parts.
I have tried searching internet/youtube for any TN7 teardown without any success (although another thread in this forum has several pics of inside of machine) and would be grateful if someone could point at a video link or explicit instructions for
dismantling the case, then I would be able to extract the stuck card and access the data on it. as it is, I can neither remove nor insert for SD card access leaving me a little lost for what else to do.
Perhaps some kind of video submission would not be out of place in a forum dedicated to such a wonderful little tablet.
I'm kinda feeling that my only recourse to access data on SD card is a two pound hammer.
Any assistance would be gratefully accepted.
Thank you in advance.
EDIT: Link to above mentioned on-site pics of TN7 internals:- http://forum.xda-developers.com/showpost.php?p=55877787&postcount=7
Further to above:
I finally managed to get the case open.
The join lies about 1mm behind face of tablet, need to squeeze in your thumbnail and zip it around the whole of the machine
where you may hear clicks as the catches are undone.
The end furthest from ON-OFF button will be most difficult and last to release. Take care not to lose the on-off button and
audio up/down rocker as you struggle to free the case back. It took me about 25 minutes (at least) to free the case back
the first time that I finally figured out where to separate it, opened it a further few times in a lot less time.
Unfortunately, once the SD card was removed and re-inserted, it continued to fail to be detected and trying anther card
also failed, so looks like I need a new tablet although I can still continue to use this one without external card.
Anyway hope above may assist someone else if they suffer similar difficulties.
NvCPLSvc problems
I noticed that after upgrading to 5.1, the process "com.nvidia.NvCPLSvc" is constantly on top of CPU usage list, and if I turn on the "Show all ANRs" in developer settings, it shows message that this process (Nvidia Tegra Services) is not responding, killing it helps for a while, but than again, it shows up and system says it's not responding.
After killing this process system works faster, no heating (before this, my tablet reached 42 degrees even if I just listened to music in headphones with screen off...), and games doesn't lag as mush. Also no other crashes experienced by me so far.

Two MOTO 4G Play Questions

1. I had to replace the screen a little while ago. All went well except that I damaged my on/off switch button and I need to replace it. I'd also like to replace the volume pushbutton as I bent, but, was able to this one back in shape. The on/off button is held in place by a piece of tape.
I can find replacement buttons for the moto g4, but, the picture looks to be different than what I remember. It is confusing that they have several phones with such a similar name. I also know that many online places don't necessarily even use the correct picture for the specific item on sale to begin with.
I did find an official motorola online forum where they just said that phone has no user repairable parts. I guess I'm a technician/user then and need a replacement part. I never did figure out how to log in to that forum to try to get an answer or even part number.
I managed to damage the part when removing it, but, I imagine they would survive pretty much everything else the might destroy a phone. I haven't really been able to find any listing of very broken ones either.
Any help?
2. I also notice that while playing music via bluetooth to my car stereo that sometimes there is some noise. It sort of sounds like you would get if a potentiometer needs cleaning or the output jack has dirty contacts or gets jostled. Then I remember there are no wires and no potentiometers involved in this situation.
I did read somewhere that this is just a problem with that phone and there is no fix. I get it, it is basically a throw away phone, but, is this really the case. Was this an issue, was their a fix? and/or is there a way to get a replacement that doesn't have this problem or some way to upgrade to another model that doesn't have this issue more affordable?
