[Q] Hardware failure? - Nexus 4 Q&A, Help & Troubleshooting

Last night all the apps on my 16gb Nexus 4 crashed inexplicably at the same time. I tried rebooting and the phone just looped the loading animation endlessly. I tried going into recovery mode and doing a factory reset but get the following errors:
E:failed to mount /cache (Invalid argument)
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
(It repeats these several times before giving up)
This morning I downloaded the Nexus Root Toolkit to try and reflash the stock software, but with no luck. The bootloader is still locked (I never had a need to root this phone... so I thought...) so it won't allow me to flash updates. When I try to unlock using NRT, I just end up in another boot loop.
I've also tried to sideload the stock image through the phone's recovery but get the same errors. If I try the "wipe cache partition" option I get the same errors (but change /log to /last_install) with 1 additional:
E:Failed closing /dev/block/platform/msm_sdcc.1/by-name/misc
(I/0 error)
So my question is, how hosed am I? What have I not done that I should try? Is there a way to flash or sideload just an unlocked bootloader? Any ideas about how to fix this unmountable E:? Or has my phone just exploded?
Thanks in advance for your help!!

Just a quick bump of this before I admit complete and utter failure....
Both Google and LG believe it's a ROM failure, but since I hadn't rooted the phone or even installed any apps not from the Play Store, I don't buy it. I've tried pushing and pulling files from adb, tried flashing files through fastboot, used the Nexus recovery tool, the command prompt and even tried the lgnpst. Nothing changes the situation. It just can't seem to read or write to E: This has to be a hardware failure, right? A short circuit or something?
Has anyone sent a Nexus 4 back to LG for repair? I have a feeling their repair, especially if it's more than just reinstalling the software, is going to cost more than my insurance deductible, so unless something miraculous changes today, I'm going to replace it that way... :/
Any ideas are appreciated.
Thanks!

Looks like messed up partitions or mmc failure - had a similar problem 2 years ago on SGP 5.0, couldn't mount system (partitions f0oked up)

this sure looks like mmc is fried. the repair will change whole motherboard. if you have some kind of fear. write down your serial number that appears on fastboot mode. then send to repair. when it get backs look the new serial. you will see its changed. the imei will also be changed as far i know

[Q] Mytouch 4g Unbricking help

I need some help with this one.
I received a Mytouch 4g and have the following errors:
It will not boot past the Mytouch 4g logo screen. However; I can boot into Hboot and recovery just fine.
It is running CWM 3.0.2.4 which is supposed to be a 2.3 recovery. Whenever entering recovery or moving around and trying to flash something it says the following:
E:Can't mount /cache/recovery/command
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
The radio is 26.03.02.26_M which is supposed to be a 2.2 radio.
I have tried to flash the 2.3 radios but they all seem to freeze up at the very end. I have let them sit for 15+ minutes.
I have tried to flash a 2.3 rom and receive an error when flashing it. Also, I cannot format system under recovery, I receive an error saying: Error formatting /system! (Helpful I know)
I have also tried factory resets to no avail. I am currently going to try to get back down to a 2.2 recovery and go from there.
Please help as it is greatly needed and appreciated!

all those cache errors definitely mean you have a bricked phone, with a bad emmc chip likely being the problem. currently, there isnt a way to recover from this brick

Ouch. Is there absolutely no possibility of anything? I'd be content with a stock rom at this point... If it's already bricked I could be a test dummy for anything risky that might work.

not that I know of, I havent heard of anyone recovering their bricked phone with the bad emmc
Answered my own question. Any other ideas feel free to post away :/
HEY guys i saw the title and thought it should be appropriate to post here, sorry if i deviate from the original question but I recently flashed 2 Mytouch 4Gs and everything worked out great i used the instructions provided by grankin01 for true perm root using gfree method through adb with visionary for perm root unlock etc etc but i didnt flash the engineering bootloader as far as i know not really sure I flashed cm7 on both devices now one of the phones has given me trouble the other is still working.
The issue is that the defective phone worked for about 2 weeks, the owner said she accidentally let the phone use all battery and die, and after that the phone would get stuck at the cm7 boot animation. I rebooted into recovery just fine and reflashed the rom. That got it working for several minutes. Then it started crashing randomly and kept freexing at boot animation, i tried a cm7 kernal and that didnt work either so i flashed virtious unity sense 3.0 rom. That seemed to work but it was freezing when i tried to install certain games well long story shorter i finally ran fix permissions for apps from rom manager and that seemed to fix problem, the phone stabilized and actually worked flawlessly after so i gave it back.
The phone worked for about another week, owner tells me that she was trying to install games (8 at a time ) and the phone was not working, so she tried reboot and the phone wouldn't reboot at all in fact it dosent even go into recovery light up or show any signs of life except when i plug it in to my computer asks for this driver QHSUSB_DLOAD so i guess its not completely dead but adb does not recognize it with adb devices command but i am totally stuck dont know what to do please help and sorry for the huuuge post!
Read the Glacier Wiki, Troubleshooting guide. Link in my signature.
It'll answer the OP.
It would be wise to look for it before posting.
For the second answer - if the phone doesn't start booting, there's nothing you can do.
Yup +1 on the brick with the bad emmc chip, classic symptoms...
I sent this...
Yup guess so. I've been trying to at a minimum get the stock recovery back on but that seems impossible at this point. Can't flash from adb or even wipe/flash from fastboot.
Argh
Okay so apparently it is going back to HTC for repair.
My problem is that now I cannot seem to get CWM off of it or anything. I tried flashing the PD15IMG to stock but receive the fail-pu. I tried with ADB but had an error. Fastboot gave me an error as well.
Are there any recommendations? I would just send it like it is since it wasn't the rooting or flashing but a manufacture defect on the emmc it seems, but I am afraid they would reject and charge me to repair. Even if I declined, there would be a $35 fee for their hassle.
I would like to have it out the door tomorrow morning if possible, so please instruct me on any possibilities. I thank you all in advance.
There's nothing you can do besides trying to brick it completely - loading PD15IMG and pulling the battery while radio update is in progress.
or fry the thing and make it unbootable lol

How would go about doing that? I can't seem to make it fully bricked by pulling while flashing a radio :/

I had a spare charging USB cable so I just cut the end off of it. CAREFULLY took the phone apart and touched the hot wire to the motherboard, but only for a short amount of time. I wouldnt really recommend this, as you could electrocute yourself if not done properly or you could cause damage to the phone possibly making it unreturnable. but hey, times get hard sometimes...**not responsible for any damage done to you or your phone, should be done at YOUR OWN risk**

Need (expert?) opinion

Hi guys,
I'm posting here after another afternoon messing with my phone.
Here's how the story goes.. My Nexus 4 fell on the ground and broke the glass, the touch screen wasn't working anymore. So i've decided to order a new screen online and replace it. This is the screen i've ordered. http://www.spareslg.com/lcd-e-touch-lg-nexus-4-lg-e960-acq86270901.html
In retrospect i used a bad guide to change it and kinda freestyled replacing the parts. I forgot to move the power and volume button. I've also wrecked my battery in the process of replacing the screen (twice). So I've ordered a new one. (yeah I'd better followed the guide on the page of the item seller, but what's done is done.. right)
Anyway, after many hours struggling with my phone I'm at this point:
The phone boots and i stuck on google logo with a lock symbol at the bottom. If I press volume down and power button I get in the bootloader.
If in the bootloader I select recovery mode the phone boots into ClockworkMod Recovery v6.0..4.3. I get the menu of CWM but and the bottom of the screen I get the following text:
Clockworkmod recovery v6.0.4.3
E: can't mount /cache/recovery/command
E: Failed closing /dev/block/platform/msm_sdcc.1/by-name/misco (I/O error)

E: Can't open /cache/recovery/last_log
E: Failed closing /dev/block/platform/msm_sdcc.1/by-name/misc (I/O error)

Then I go to "Instal zip" install from sideload:
Sideloading works in my command promt. I get 100%
In the phone this happens after the 100%:
Restarting adb...
E: can't open /cache/recovery/last_install
E: faild to open last_install: No such file or directory

E: Can't open /tmp/update.zip (bad)

So I figure something is wrong with my internal memory. Just guessing. That's why I need some input.
So my question is: What's causing this problems preventing me to flash the 4.4.2 stock rom?
Did I destroy some hardware?
Thanks for reading,
Semi
yes, that's clearly a fried eMMC... since the recovery can't do anything about that, try flashing stock images via fastboot (because fastboot is "stronger"). if that didn't work, then... well... i hate to say it to a nexus user....

Thanks for the quick reply!
I've done "fastboot flash system stockrom" and In command prompt everything goes well until "FAILED: flash write failure"
The eMMC is on the motherboard and that costs 180 euro, not really worth it I guess to buy a new one. Is there any possibility that I made a mistake that's reversible by opening the nexus 4 again?
IF someone else could confirm this theory (which sounds credible) that I should replace my main board in order to get the phone working? No disrespect inteded to Riro Zizo, only want to be 100% sure. Thank you!
sure! you can't be 100% sure until you get others' opinions and experience too... but i say there's no way that that can be fixed by reopening it. not even replacing the eMMC itself could work since the pins are just way too smal to work with.
sorry

There's a small chance the new board isn't fitted quite right and it's shorting out or something, but most likely you've damaged something on the board during the repair.

Well yeah, it's the same board that I've moved. Too bad, lesson learned
I wonder one more thing.. When I was googling on possible causes someone somewhere, suggested that the guy needed to repartition his storage space or sth like that. Any chance that's a possible solution? Just to be 100% sure I can let it go LOL
Bummer! :-O I like tinkering and all, except my precious. There's two options, (for me) Service Center or new phone! So far, it's the new phone option that win the game. I know this doesn't help your present issue in one way, but it seems that you might not have a choice. Good luck to you.

You shouldn't need to flash a phone after a mechanical repair. I take it it still booted with the cracked screen? The fact that it doesn't now pretty much proves it's dead.

Yeah that makes sense. Thanks alot guys. Appreciated.
Freaking eMMCs! had a similar problem with flashing a dead phone, my GSII, ended up sending it to the repair center, luckily was still under warranty.
And about playing with PIT files, it's usually the hopeless case, but most of the time it doesn't work, and even if it does, the phone doesn't live afterwards much longer, the sd card still unstable.
I'm not an expert though but I guess it's a wise idea to let it go, and get a new android, maybe a N5?

[Q] Is my tablet beyond hope?

For the last two weeks, I've tried pretty much everything I can think of to get my TPT booted again. Symptoms of its current illness include:
Lots of error messages when booting into CWM recovery ("E:Can't mount /sdcard" for example)
If I attempt to boot normally, I get stuck on the Lenovo logo screen.
Randomly I'll boot into CWM recovery and get its logo on the screen, and a line of text, but no menus.
Other times I'll attempt to boot into CWM recovery, and just get a blank screen
So last night I used nvflash to put a new CWM recovery into partition 6: after which I was able to boot into CWM with no errors. (Yay) However, when I tried to reinstall CynogenMod (whose zip file was sitting on my external sd card), it hung during the installation. I rebooted anyway; this time it got as far as the CyanogenMod spinning logo and hung there. I went to bed, and seven hours later it was still spinning away.
Then I rebooted into CWM (without errors) and managed to install CM ROM this time also with no errors. However, again I can't boot. I get as far as the Lenovo logo, and if I boot into CWM recovery I have all the mount errors again.
Along the way I've erased the cache; done a factory reset, etc.
So: nvflash, new CWM recovery (but still errors), reinstalled CM ROM, but can't boot into it.
Any suggestions? Has this machine packed it in - is its hardware faulty in some way? Or is there something I could try which I haven't already?
Thanks folks - I think I've reached the limits of my fixing ability, and would be very gratefiul of some advice.
Thanks again,
Al
In CWM check to see if your /System folder is mounted with read-write privileges or only with read-only. If the former, then your bootloader may have locked itself. Also, what is your device model? If you have a have a US device then it cannot be unlocked as it has been encrypted by Lenovo...
Sent from my ThinkPad Tablet using Tapatalk
Thanks - it's not a US model (I bought it in Australia, where I live). I thought the bootloader was unlocked because I could use nvflash. When I boot into CWM recovery, I can't mount /system: if I try I get the error "Error mounting /system", along with other errors about not being able to mount or open /cache/recovery/{command, log, last_log}. And since I can't mount anything, I can't install zip files.
I can't remember the device model, although I suppose I could use nvflash to trawl through the partitions somehow. (Since I can't boot the device I can't do the usual thing of checking out the system settings.)
Anyway, at the moment it won't boot beyond the Lenovo logo, even after putting on a new CWM recovery (with nvflash - but as we see above this new recovery is still not working) and reinstalling a ROM (with CWM recovery, which I managed to do on the one occasion I could boot into CWM without mounting errors). It's a right pain, that's what it is.

Well there may be hope yet as I understand (not sure) that only the US models shipped with a locked bootloader. My US model locked itself and after some research I eventually replaced the motherboard with one from eBay. There are threads around here regarding the bootloader that might have a few "options" for you to try. On the other hand I read on the Lenovo forums that Lenovo actually replaced motherboards (during the warranty period) due to failures which caused the nand to lock read-only. If the "options" don't work then the latter may be the case and you might want to consider my approach or just move on to a newer device. Good look...

I never thought of replacing the motherboard! I'm happy to try it, though, given instructions, and the correct (ROW; ie non-US) motherboard. Is it hard to do - and where can I find out how to do it? And how do I find out exactly what model I have?
Thanks for this - I'd really like to get this beastie working again.

No offense intended but you are somewhat peculiar as you are familiar with NVFlash, can determine which partitions to flash with the correct images but you don't have a record of, or can't find your device's model number? Check on your SD Card port flap (or your invoice). Then check out this page for details.
However if you decide to replace the motherboard then search eBay for "thinkpad tablet motherboard" and choose either of the 1838 or 1839 options. Any will fit and work but you probably won't get your (non-US) choice of replacement motherboard so will probably just have to get what's available.
See here for some basic dis-assembly instructions. Then just take you time and the rest will be obvious. Good luck!
Thanks for that! I tried responding earlier, but my post was blocked by the system. Anyway, I'll check for a new motherboard and have a go installing it. Do you know how I might prevent this from happening again?

No problem at all.
"I'm in the same boat": I replaced my motherboard with another US version about 6 weeks ago, rooted, installed CWM recovery and steady so far... "with fingers crossed"...

[Q] Bricked Nexus 4

Hello Guys,
yesterday I restarted my Nexus 4, running the cm-13.0-20160520-NIGHTLY-mako. It stuck at the bootlogo, so I tried to reflash it in the twrp 2.8.7.0 recovery. But I got the error message "E:/ unable to mount /cache".
After that I was trying to solve this issue by wiping the cache, but I got the same error message -> The phone wasn't booting
From now on I did several things to solve my problem. I don't know the exact order.
- I've downloaded the Nexus Root Toolkit from WugFresh -> Tried to use the Flash Stock + Unroot Option with Soft-Bricked/Bootloop status enabled -> I choosed the 5.1.1 Factory Image -> In the cmd window, I get in every point the same error message "Falied (remote: flash write failure) -> I get the same message when I'm trying to manually flash each part of the factory image via fastboot
- Within the Toolkit I also tried to format cache, system and Userdata, but afther this I get the same error when trying to do the step before
- I think also used the Fastboot Flash options, but I'm not sure.
- After that I attempted to flash the cm13.zip via adb-sideload in TWRP. Here is a part from the error message I get:
"(...) could not detect filesystem for /dev/block/platform/msm_sdcc.1/by-name/system, assuming ext4
mount: failed to mount /dev/block/platform/msm_sdcc.1/by-name/system at /system: Invalid argument
unmount of /system failed: no such volume (...)
E: Error executing updater binary in zip 'sideload/package.zip'
E: Unable to mount '/data'
- In TWRP the Internal Storage is shown with 0mb
- Currently only the bootloader is working fine and I also can get a fastboot and adb connection to the phone
-> Loading the recovery is only possible by booting a recovery image in fastboot
Can somebody tell me if it is possible to restore my Nexus 4 and how to do it?
Thank you in advance :fingers-crossed:
PS: I hope I mentioned all the important points. If some information is missing, feel free to ask me.
Did you try to manually flash the latest rom?
Did you try to flash a stock 4.2 rom?
Tried different USB cables and USB ports?

Thank you for your answer.
I tried to flash the newest cm13 in TWRP and with adb Sideload. I get the same error.
Also the 4.2 Stock rom doesn't work. Same problem as with the 5.1.1 factory image.
I also switched the cable and the USB ports, but it leads to the same error messages.
Try flashing the userdata.img file in fastboot. As soon as userdata finishes flashing, use the buttons to boot into recovery and perform a factory wipe. User the usedata.img file included with the stock ROM you flashed.
From what I see, your partitions got completely messed up. I reckon if it's fixable at all (assuming your chip ain't dead), the only thing that can fix it is fully reflashing everything via emergency mode. Now I can't seem to find the exact link, but I do know there was a thread on xda with instructions and everything. I'll keep digging around to see if I can find anything and then I'll link it here.

Does the bootloader remain unlocked after rebooting? The emmc chip could be messed up and need replacement.

Unfortunately yes. After locking the bootloader via fastboot, the bootloader is marked as unlocked after rebooting.
Do I have to change the mainboard?
This confirms that the emmc chip is damaged and can only be fixed via a motherboard swap.
I had similar problems with two nexus 5 phones where I would unlock the bootloader but would always relock on reboot.

Aye that's the thread I've been talking about. And yeah, the links are down for quite a while, I reckon the OP doesn't maintain it anymore. Anyways I used the tool once, I found all the files by Googling for like 4 hours or so - the most difficult one being the .dll file and getting the program itself to run. I'd upload them to you but there were on my C disk on my main rig and that got wiped when I reinstalled Windows :S I'm sure the files are on the net even now tho, I remember getting the .dll file from some Chinese website, Chrome's translator gave me enough info to actually download the file. Once I got it up and running the flash was OK, I've tested the method from that thread myself, the only problem is getting the files from the links that are down. I wish you good luck in your search for them, I know what an awful feeling it is for your nexus to die, my mako is still my daily driver, still kickin' ass

Ok. Doesn't sound very good.
Nevertheless I will try the method of nerotNS, if he finds the thread.

I did however have to change the motherboard out, since, while the flash was ok, the chip was not, so it didn't help much. I had an issue with my /data partition where it was completely gone, and the while filesystem got messed up, the only thing I could boot to was bootloader and even that only while on charger. Eventually I swapped my motherboard with a friends who didn't need her nexus 4 anymore and now it's ok. I suggest you first attempt the method from that link and if that fails, then you should resort to getting a new motherboard, but imo only if you can get it either dirt cheap or in a way like I did. Caching out around 100$ for a new nexus 4 mb, with phones like nexus 5X 32Gb costing 300$ is not a good investment if you ask me.

Aye that's the thread I've been talking about. And yeah, the links are down for quite a while, I reckon the OP doesn't maintain it anymore. Anyways I used the tool once, I found all the files by Googling for like 4 hours or so - the most difficult one being the .dll file and getting the program itself to run.

I found all the necessary files for doing the method subscribed in the thread, but afther flashing the firmware nothing changed. Only thing that worked was the bootloader, everthing else still wasn't working.
Fortunately I had a broken Nexus 4 from a friend. So I switched both mainboards and my Phone is working again
Thank you for your help.

Awesome, glad to be of service

Cant flash an OS - "failed to mount partition '/vendor' (invalid argument)"

Hello!
Now, I know this problem is in other threads. But the only reason why I'm posting a new one is if either that thread had died or the solution wasn't applicable to me (it didn't/doesn't work).
So! What happens is when I try to flash a file to the system or vendor I get this error.
Code:
failed to mount partition '/vendor' (invalid argument)
I've tried in TWRP and the bootloader fixes. And now, I currently have no OS.
What I've tried is as follows:
Flashing just the vendor (bootloader/TWRP) - ends with the vendor error.
Flashing .zip ROMs (bootloader/TWRP) - ends with the vendor error.
Trying the usual return to stock procedure - ends with the vendor error.
Repairing partition in TWRP - Says operation completed but the error is still persistent.
Basically. Nothing works because the Vendor partition is unmountable.
What should I do? I have no idea what a fix could be.
Alright, so i've tried some things. I guess I've fixed it but I got a new problem. In the end what fixed it was wiping every parition and rebooting TWRP and then flashing a system image then vendor image. When i say image i mean a manual .img flash instead of a .zip file.
The problem now it that because every was wiped, i no longer have a recovery. When i boot into recovery i get "No command". So now im stuck with stock android 8.1 and a unlocked bootloader that won't do anything. Every time i try and flash a partition i get
Code:
FAILED (data write failure (Too many links))
or
Code:
FAILED (command write failed (No error))
Any tips on getting a recovery installed so i can return to my custom ROM ways.
Thanks for any help in advance.

Done some research and it seems to be a cable issue of all things with this errors. I bought a new one that should arrive by amazon tomorrow. Will see if that fixes it.
As the nexus toolkit ive been using that a lot. With that i don't even get an error but it never works.

Yeah well, it seemed the cable wasn't the issue. I wouldn't of thought it was myself but yeah. Seems my initial thoughts were right as the cable didn't fix anything. Same errors, same problem. So all my research has lead to nothing. So how can I fix this? I'm out of solutions. I need xposed at least on my phone to be usefull since I can't disable the screen off during calls.

Have you tried wugfresh Nexus tool kit?
Just thought I'd let you know that I have fully restored stock and locked my bootloader, and if I boot recovery I get " no command" too. Seems latest recovery image does f*@k all.

No, I haven't. BUT!!! I have fixed it...
So the issue that I was having is that I bought a replacement charging board (the PCB for the USB dock.) I replaced it because I had a faulty microphone on it but the USB port was fine. Putting in the old one fixed all the issues I was having. Its meant to be an OEM part so I didn't figure it would be the problem but it was *sigh*... So I take it where I got it from Replacement Base wasn't legit? Ah well, at least my problem is fixed and if anyone gets the same problems they might find this thread.
Thanks for your support thought dude! It was nice to have someone to ask.
