So, my tablet shut itself off.
I turned it back on, and it started up the activation process / new device walkthrough that you get when i first got the device. All my apps were gone. Play Store crashed if I opened it. Restarted device, and it started up the activation process again. Attempted a factory reset from the settings menu. Nothing happened. I dont mean nothing changed, but literally nothing happened. Selected reset, said yes on cofirmation, and nothing happened. Held down the volume down and power buttons, let go of power button, then held all three to get to the alternate factory reset option. Selected it and got a series lines of "failed to mount". Restart device, nothing has changed.
Any ideas on what exactly has happened?
Any suggestions on what to do, with detailed instructions?
UPDATE:
Tried a variety of rooting options, which are apparently very limited for the v410, to see if I could fix my issues.
Purpledrake brought me to the recovery mode screen which ended in the same results: "failed to mount"
OneClickRoot and KingRoot both just got hung up at 0%.
Would really appreciate some insight into what the issue is, and wether it is something I can fix myself.
Kingo Root hangup
Did the same thing to me when using it from the PC, but I just rebooted my V410 and ran it again. It worked the second time. Didn't do me much good, though. Can't get into recovery, can't unlock bootloader, can't find a way to install CM on this thing.
I still have this device sitting around. I would love to be able to fix it. Hoping someone out there can help me out. It seems to me that its a memory issue, since in settings under storage, it says there is only 100mb of available space, and that 15 of the 16 total gb being used is system data.

Not sure what's going on here.
My Nexus 7 has recently begun a reboot-load OS-load apps-reboot cycle that I'm at wits end to fix.
I've tried uninstalling some apps that I thought might be the cause (AutoShare and Tablified HD Market), but whenever I remove them, the next time the tablet boots up, they are still there.
I've also tried to get into safe boot mode while the tablet is booting. The dialog pops up for the Power Off option, I hold that until it prompts me for a Safe Boot, I tell it OK but still the tablet reboots as normal with the same apps loaded as usual.
Also, I was previously rooted and unlocked, but the last Android update torpedoed that, and because my USB port doesn't work, I have no way to reinstate my root. As a result, I have no Recovery, which eliminates a couple of other options.
Oh, and I also tried to do a Factory Data Reset, but in the same way that it won't recognize the deinstallation of apps, the Factory Data Reset is not working.
Anyone seen anything like this before? Any suggestions?
Hello XDAers,
I am a real noob at rooting or android-related, and a true one voided of any knowledge regarding anything IT- related.
So dear veterans, please go easy on me.
Due to my prior success of rooting and flashing my Nexus 4 successfully a few months back with no issues, I decided to give it a try to flash a custom ROM for my dad's LG Optimus L7 - which seemed an easy task compared to configuring my Nexus 4 - since there was no need for inputting any command lines or any dealing with the abd (using the easy shortcut, that is).
So, I followed the guide here: http://forum.xda-developers.com/showthread.php?t=1906133 ...
I first factory resettled the phone because it was bloated, then applied the "RunMe.bat" from the "What you desire!" folder. (Everything was already backed-up beforehand.) But the process didn't success until I've retried again and again by re-plugging the USB in because the application/PC couldn't detect the phone. In the same time, I was running KDZ_FW_UPD.exe in the background, so unexpectedly for me the phone shut itself and pushed itself to a vividly green emergency screen, then in a few seconds switched back to a screen of purple-white-blue glitches. I had to close KDZ_FW_UPD.exe without knowing what quite happened since it seemed to be the cause and restarted the process with RunMe.bat.
I didn't manage to "Restore" it first due to the fact that the phone stopped responding due to a lag asking for an encryption key. It was lagging so hard and I had to close the cmd around 5 tries while it was processing, but succeeded later on.
And then, to verify whether I've actually suceeded in rooting L7, I installed Root Checker from the Play Store. And again, for the first few tries the program froze on screen for a long period of time due to "system performance", but after rebooting and restarting the app a few times again, the ROOTING proves to be a success. Just to be sure, around this time I've reloaded KDZ_FW_UPD.exe and it suceeded.
So I went to install CWM and ES. CWM for recovery boot and ES for removing pre-installed system apps as the phone was lagging so badly. I've downloaded the CWM restoring(something like ~6.0.28?) first and tried fastbooting immediately right after, but instead of getting the fastboot menu I got a screen emptied in black with these words:
[5020] "Secure booting error"
[5020] "Cause: boot certification verify"
No hard keys could do anything on the presumed "fastboot", and so I had to hard boot again. I thought that it might be due to the lack of memory(checked on ES later on that it was 310~MB/2GB), and so I've used ES to uninstall a lot of system apps which I deemed uneccessary. So I've Googled a bit and it became apparent to me that that I've didn't unlock the device properly, so lurked around and found a file called L7CWM that is supposedly to resolve my problem, but I presume that it's the CWM recovery image that I've installed. So in the end, I didn't bother with it but kept it on tab just in case.
I repeated the same process with CWM again, but this time, the screen was joined with all kinds of flowery glitches. Restarted the device, and it went only downhill: now the Home launcher stayed all pitch black and nothing appeared. I waited a few minutes, but nothing there until the notification bar appeared. The home screen is apparently dead, and so are the menu keys. Switched to Nova Launcher(installed it just in case Home Launcher fails), and still dead. I couldn't access using any of the menu keys and had unusable launchers.
Hopefully I could still access to the settings from my status bar, but when I did, it started crashing immediately.
I've repeated the attempt a few times after restarting the device a few times, but nothing helped. It only got worse that the when the launcher did SEEM to work. It only showed the wallpaper without showing any of the icons/apps. And crashes again.
I could still access to the App menu via the settings, but couldn't open any of them and when I tried to uninstall them, the screen frozes immediately right after I gain access to the page (white page though) and gain this message: "Unfortunately Package Uninstaller Stopped!"
Then I convinced myself that the only thing I could do at the time was to factory reset the phone and then everything would go alright since I've just had to restore the system apps.
But then the black screen of death came right along with it:
"Secure booting error"
It seems that I'm out of luck... ... But just to check if I'm still left with resorts, I've downloaded the L7CWM file online...
... ...but it still didn't help.
So now I'm being left with no other choices other than asking for help. I never really understand what KDZ_FW_UPD.exe does since I had the LG Driver already before installing it, which I presume was for updating the phone to a newer or older version. And too complex tech articles are kind of alien for me.
EDIT(1 hour later): Okay, now I figured out the reason why L7CWM didn't work was because I didn't extract it to the right folder (after double checked via notepad that I was supposed to directly put it into the C:\ drive). Now it worked(?), but then it didn't.
After launching Flash_Bootloader.bat:
This message now appeared on the L7:
"Sorry!"
"SuperSU is not responding.
Would you like to close it?"
"Wait - Report - Close"
and a few minutes later
"Sorry!"
"Unfortunately, SuperSU has stopped."
"Report - OK"
Now I think the bugs till now happened was due to the fact that I've deleted a file that was required for me to launch apps... Now I just need the right fix.
After 5 minutes of screen inactivity the phone restarted by itself, kind of creepy... ...
Flash_Recovery.bat did nothing.
Reboot2Recovery.bat made it reboot but still struck on the same menu.
Nothing seems to be effective via the phone anymore, seems like I have to rely on abd but then again I don't know how... ... My dad is also f*cking pissed off ^ ^;...
__________________________________
I think that I explained the logs pretty precisely in case I missed something... I'll be very very very very very very thankful if someone could tell me what has caused my phone to fail though.
For references, here are the phone's specifications:
Model Number: LG-P705g
Android version: 4.0.3 (Stock)
Rooted:Yes (root checker)
Baseband version: MSM7227A-1-AA
Kernel version: 3.0.8-perf
Build number: IML74K
Software version: V10e-AUG-10-2012
If I don't get the phone fixed to being usable soon I think that I will get butchered real hard... ... Preferably needs a step-by-step guide made for toddlers... ...
remove the battery for 10 seconds,put it back pres VOL+ and VOL - same time and than press the power button.when you feel a vibration press for many times the button wich is down in right,try for many times and maybe it will working :}

simple answer for your
just download your stock rom
go to emergency mode
and flash that stock rom
Two days ago my wifes 1st generation Nexus 7 refurb started giving the "Unfortunately, NFC service has stopped" error. You click OK and the error instantly pops up again. There is a moment to click on something if you're fast and I've been able to click on settings but when settings opens it's nothing but a black screen with no options. This means that I can not enable usb debugging. I have tried quite a few different processes, ADB sideload, going through the bootloader, but they all seem to require usb debugging and the tablet is never recognized. The tablet is stock but I have no way of knowing what version of android it is currently running with the blank settings window (unless you can give me a tip on that). Have done two wipe/factory restores on it and the error comes up right at the first boot screen. I am willing to pursue any option to get this tablet in working order. Rooting, flashing, whatever but I am a novice in the world of android rooting. It was purchased off groupon (won't make that mistake again) and the 14 days are past so If I have to send it in, it's cash money out of our pockets.
Do I have any options? Thank you for your time!
Most frustrating of all is that everything else about the tablet seems to be functioning normally. I can install apps from google play. I can't really run many of them though.

If the tablet has never been rooted, and the factory reset procedure seemed to complete successfully, then your symptoms suggest that something is wrong with the /system filesystem - which, for stock devices is never modified (always mounted read-only).
So that in turn suggests *perhaps* flaky hardware - probably the flash memory chip - that has gone awry and is the root cause of the problem.
It is conceivable that you could go through the process of unlocking the bootloader and re-flash a Google-provided "factory image", and that the problem will go away. But if the root cause is really a flaky flash memory chip, it will very likely return with a vengeance, and your efforts will be for naught.
There is something missing in your narrative, however - if the appearance of the "NFC Service has stopped" dialog on-screen prevents you from interacting with your (intended) foreground apps, how were you able to perform a factory reset and then follow that up with a tablet configuration? (e.g. to get Google credentials on the tablet so you could push apps to it by using a PC Web browser from the Google Play market).
If you are unfamiliar with rooting but still want to proceed with reloading the factory images, you will have to follow the Stock Recovery tutorial threads. Many users - especially those with Windows machines - seem to get stuck at this step, although truth be told that has nothing to do with Android, and everything to do with Windows Driver Installation Hell.
Note - specific to your situation.. You do not need to enable USB debugging to re-flash factory stock images. You only need to communicate with the device (booted into bootloader mode) with the "fastboot" program. For this you only need working USB hardware - not "adb".
good luck
BTW, note that you can perform a factory reset in the stock recovery without launching it from the O/S. The sequence is:
1) Turn the tablet off (not screen off, but powered completely off)
2) Boot into bootloader mode by holding Power+Vol-Down together (hold them down until android lying on its' back shows up - about 4 seconds)
3) Using the vol-up/vol-down button, select "Recovery Mode" on screen and press the power button
At this point the screen will go black. Wait about 10-13 seconds. The screen will remain black even though the stock recovery is now running. To get the screen to show the (stock) recovery menu,
4) press and release the Power & Vol-Up keys simultaneously.
The stock recovery menu should show now up. If it doesn't, try again. (After 60 seconds if you have done nothing, the tablet will reboot to the "normal" OS).
5) Use the on-screen menu to perform a factory reset (follow the directions on-screen for key usage).
Thank you so much for your response! The unanswered question is that I managed to put in the network info and what not during setup by hitting OK on the error and tapping the letter in the moment before the error popped up again. Not a fun task!
I've been trying to flash and after installing the google usb drivers it's still doing the <waiting for device> for infinity. I think I will have to bite the bullet and send it in. You saying that it might be a flash chip is kind of comforting because I think I might have bashed my skull against this issue forever before giving up!

I have a Nexus 7 sitting in front of me that was dropped off by my aunt in hopes that I could repair it for her. It doesn't look too promising, but I thought I'd consult the mighty fine people here on XDA before I give her the bad news. Here's what she says happened. Yesterday, while preforming day to day activities on it (browsing internet, Skyping, Facebook, etc), the device completely froze. After holding down the Power Button and forcing it to shutdown, she booted it back up. Everything seemed to functioned properly for about 30s - 1min when, at that time, the device turned off and rebooted on its own. After booting back up, it started to repeat this cycle. Basically getting stuck in a bootloop. I personally have never witnessed a bootloop like this before, where the device successfully boots up completely into the OS before turning off and repeating. I'm more used to dealing with ones where it might go as far as the manufacturer logo and then repeats. So anway, as I stated, I only have a 30s - 1min window where I can make changes in order to troubleshoot. The first thing I figured I should do was to go into "About Device", turn Developer Mode on and get USB Debugging enabled. I was able to do this and used "adb devices" to confirm its connection to my computer before it looped again. After its next bootloop I headed back into settings because I wanted to take note of the Android version she was running. As I was navigating there, I noticed that the Developer Options were no longer active. Basically as if I hadn't enabled them yet. This made me start thinking that changes being made on the device weren't sticking. I decided to make a few visual changes to the home screen and see if they were still there after the next bootloop. I uninstalled an app, rearranged icon placement, and changed the wallpaper. Once it shutdown and booted back up again, everything was back to the way it was before the changes had been made. The app I had uninstalled was still there, the wallpaper reverted back, and the icons were back in their original location. At this point I decided to see if I could reboot into Safe Mode. Unfortunately, this doesn't work. I am able to get the reboot to Safe Mode confirmation box and tap "Ok" but it remains in Normal mode when it boots back up. I eventually tried to boot into recovery and preform a Factory Reset. I was able to get into recovery and reset the Nexus. Or so I thought. Instead of seeing a Device Setup screen after it wiped, like I assumed I would, it booted up and still had all the data on it. There were no errors during the wipe and it was confirmed with "Data wipe complete." afterwards.
I am absolutely lost. I've never dealt with such an unusual issue before. Especially with it not even reacting to a complete data wipe. So, just to recap . . . I only have 30s - 1min available to interact with the OS before it reboots itself, any changes made during that time don't stick, Device is successful booting into Stock Recovery, and I can successfully get a Fastboot connection when booting to the Bootloader.
Luckily she has come to terms that this might not get fixed and has decided to go a head an order a newer 2013 model. I'd still like to try any solutions that you all might have. Just in case there is a slight glimmer of hope.
Oh, and one last thing I should mention. I tried to see if I could get the bootloader unlocked but it didn't work. This is the first Nexus I've ever had in my possesion, so I'm not really familiar with the tools available for it. I found WugFresh's Root Toolkit and attempted to Unlock with it. The process seemed to go as it should and I didn't receive any errors on the tablet or in the software. However, in the end, it didn't make any changes to the bootloader.
same problem
I have the same problem as you.
Did you find a solution?
Can anybody help us?
Thanks.
I have a similar problem, but I think mine is related to the bootloader.
I'm stuck on 3.34 and that's where it fails ever time I try Wug's Nexus Tool Kit.
Have you tried Nexus Tool Kit yet?

I have tried factory reset from recovery, no errors while wiping but when device restarts nothing has happened: I only have a 30s-1min of old system with all my data and apps or directly bootloop.
Also I have tried flash factory images with Nexus Tool Kit and directly from bootloader. No errors while flashing, apparently has flashed new image system. When device restarts nothing has happened: bootloop or my old system with data and apps for 30s before restart.
Myself and a few others are having the same problem... please keep us updated if you find anything out.

Please help me. I have a Huawei Y625 (a bit more than a year old), it is NOT rooted. I have never attempted to customize it/tinker around with it. I don't even know the exact terminology so I'm sorry if I get something wrong.
Yesterday it suddenly went into a bootloop, it kept saying "DataBackupStart" with a bunch of processes failing.
I held volume down + power button, which opened a menu entirely in Chinese.
I clicked everything on that menu, but those were just some tests, like camera and sound test.
Then I powered it off, held volume down+volume up+power button this time, and it finally got me to recovery mode I think.
I wiped cache, and I wiped all data, which did a factory reset. It was OK with me because I just want it to work.
Then I tried to reboot it, but then it started behaving even worse. It will not turn on until I remove and put back the battery, and then it will vibrate, show the Huawei logo for a few seconds and then turn off again. It never got past that logo, except if I turn on recovery mode.
I found its official stock files, put the 'update.app' in the dload folder on sdcard, then tried to activate that rom in the recovery mode. It says 'error, status 7, installation aborted'. I googled it but I do not understand a thing, I really don't get these tutorials and I don't know what to do about that.
I tried downloading Marshmallow 6.0 version, because I thought maybe upgrading Android would help, but I cannot find any download links that work.
I am out of my mind, I need my phone and nothing I found on the Internet has been helpful. I don't even know how it came to this since I have never even attempted to root my phone! Please help me, thank you. :crying::crying::crying:
