[Q] NFC error puzzle. USB debug not an option

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!

flashed the wifi fix for the TMObile us version (from the X Note rom page)and was able to get out of the loop.

[Q] SAM+CWM bootloop nightmare (& my mom-in-law will kill me!)

UPDATE: Problem solved! Subsequent attempts at Odin flashing succeeded. So...Nevermind!
Hello XDA sages!
I'm an avid Android user and I like to mess around, but I have no genuine technical skills or training and it's now bitten me pretty hard. I just got engaged and I was trying to clean out my phone and gift it to my new mother-in-law...with disastrous consequences. So this is my SOS to this incredible community! (Please note, I have searched many other Note 2 bootloop threads but I've seen nothing describing my situation and their solutions have not helped. Though I do apologize if I've missed something!
My current situation:
* Upon restart, the phone (Note 2 GT-N7100, unlocked) is stuck in a terrible bootloop, where the "Samsung Galaxy NoteII GT-N7100" logo appears for 6 seconds, and is then replaced by the Clockwok mod recovery logo (not recovery mode screen, just the hat+geer+orange arrow logo in the center, with "ClockworkMod Recovery v6.0.4.3" in small letters at the bottom). That logo lasts for about 1 second and then it goes black for 1 second, then repeats with the Samsung logo. And so on.
* Many other threads have suggesting entering recovery mode by holding power + home + volume up. This only causes the Samsung logo to refresh every few seconds (i.e. it eliminates the Clockwork mod logo interlude but does nothing else)
* Down+power+home does stop the loop and change to the custom OS download option screen. Pressing volume up then does enter the "Downloading..." screen with the picture of the green Android. (pressing volume up restarts the phone and the loop begins again).
* I've tried loading a stock firmware package onto the device in this mode with Odin v.3.0.9 (obtained via this post) but it doesn't recognize my device. I'm guessing this is because USB debugging was not turned on before the crash.
How I got here:
* I first rooted and flashed a custom rom several months ago using the Cynogen Mod custom installer. I installed the only "stable" release for the N7100 (here.)
* About 1 month ago I used the Rom Manager app and CWM to flash OmniRom, from a zip file on my external SD card. Just before the crash happened last night, I successfully completed an OTA to the latest OmniRom nightly.
* As mentioned, I was preparing the phone to be gifted to my new mother-in-law, and wanted to clean it out. I started by booting into recovery mode (from the Rom Manager app) and then initiating a factory reset.
* Upon rebooting, I noticed that somehow a bunch of my data was still hiding on the phone. Photos and videos and some songs were mysteriously still present, and the storage analysis in settings showed only about 6 gigs were free out of 16. A subsequent Factory Reset did nothing to change this. (All other aspects appeared to be working perfectly, however, as far as returning to a clean install of a fresh copy of OmniRom Android 4.4.2 -- no account data was preset, all my apps were gone and all the stock apps were in the default folders, etc.)
* I booted into Recovery Mode and initiated a "Media Data wipe" (I think that's what it was called) in an attempt to clear out the stubborn media files that weren't being erased.
* I then initiated a "data wipe" (which appeared to just be one level of storage hierarchy above the media data wipe I had just completed).
* I'm pretty sure I also separately initiated a "cache wipe". (But not a "Dalvik Cache" wipe that I have seen referenced on other threads, as I don't believe I saw a reference to that within the recovery mode interface).
* After these wipes I restarted, and all appeared to be fine. The stubborn media data was wiped clean. Finally, after logging back into my Google account to use the App Store to download Rom Manager one last time, (and I honestly can't quite remember why I needed to that) I wanted to complete the process with one more factory reset to eliminate my account data before handing over the phone. This time, I initiated the reset from within the settings menu of the phone in normal operational mode. (This was the first of the various factory wipes I've mentioned that I initiated this way -- all the other factory resets were initiated from within recovery mode).
* I think this is when the current loop started. But to be embarrassingly honest, I had the phone face down and didn't look at it after initiating that final factory restart until I subsequently popped out the battery in order to remove the SIM card. I think the factory reset was complete by that time, but I'm not sure. (In other words, I might have interrupted the factory reset by removing the battery before it was complete).
* After that point this evil loop began.
* To my amateurish eye, the two leading contenders for how I did this are a) the "media wipe" or "data wipe" which I completed before the penultimate restart (although the phone did boot and operate just fine after those were completed, or b) the final factory reset which I may have interrupted by removing the battery.
Three other notes which may or may not be relevant:
* Every time I did a factory reset or data wipe and then went to restart the phone from within the recovery mode, a warning screen came on saying that something might have messed up root access and asked me if I wanted to fix. I always said that I did,
* I had selected TWRP recovery in the Rom Manager app on the advice of the Omnirom site, and I think I saw a reference to TWRP on the recovery mode screen, but I had previously installed ClockWorkMod Recovery and thought maybe that was still active in a way it shouldn't be. (I can't remember what those indications were exactly, but I think it might have just been seeing the logo in the recovery page). But the presence of the ClockWorkMod Recovery logo in my evil boot loop makes me think this may be relevant.
* Before my first factory reset I had made a full backup copy of the current Rom (omnirom) onto my external SD card, which is still in the phone.
I would be eternally grateful for any help, tips, references or suggestions! My fate is in your hands!!
Many thanks,
- Your overeager n00b

Try simple things first. Reinstall kies so you know drivers isnt corupted and then flash stock rom with odin. And also try to switch usb cable and if that doesnt work switch to another pc. Try that and well go on.
Edit: i see you solved it gj.

Do not touch somebody else's phone if they are going to kill you when something goes bad

Next time better think twice

By the way, I recommend changing the tag to [SOLVED] :good:

[Q] Blank screen software problem (Never dropped and no water damage)

Had my Galaxy S5 G900F for under a year and had it rooted within a week of owning it. There were no problems with the phone at all until I installed lucky patcher. Lucky patcher was not working so I restarted my phone then when it came back on the screen never came back on. I was still receiving text messages and phone calls but the screen was blank and touch was not working. I know for sure that I can still get into Download mode by having it connected to my computer it is detected in Odin (download mode and recovery have a blank screen too). I am unsure If i can get into recovery and even if I got into it I wouldn't be able to see what I am doing.
I am thinking I need to wipe data and cache but I cannot as I cant see recovery.
Is there anything else I can try?

Do you have Android SDK Installed on your PC and have a custom Recovery on your phone.
If so you can try to Factory rest this way, by connecting your phone to your PC (phone turned on as normal)
Go to the SDK\Tools folder and click monitor.bat the Android Device Monitor window will open (it is slow to load), you should then see your device on the left and a list of folders and files on the right, if you don't make sure the DDMS button is selected and the file explorer tab selected.
Now try the below process
1. Go to the SDK\Platform tools folder, hold down the shift key on your PC and right click the mouse button and select Open Command Window Here
2. Type adb reboot recovery and hit return and wait for the phone to reboot, you can check this in the Android Device Monitor window
The device and files etc will disappear and when booted into recovery appear again, if the device doesn't appear then the rest of this process won't work if it does and you have the device and the list of files and folders again then it should
3. now type adb --wipe_data and hit return, leave the phone alone for a minute or two as you can't see the screen you can't see the progress
4. after a couple of minutes type adb reboot and hit return
The device should hopefully reboot normally, if it doesn't then unplug the USB, pull the battery wait a minute reinsert it and boot normally
This should work as long as you have a custom recovery and Developer Options USB debugging selected on your phone

Okay so I just turned my phone on to try what you said and I didn't even get to try. It wont boot normally now. It has the glowing blue light at the top (Usually on when Samsung logo is on) so I am guessing its in a boot loop. Screen is still black

Help: G4 Plus won't start after accidentally hitting "Open" on icon pack install.

Help: G4 Plus won't start after accidentally hitting "Open" on icon pack install.
I got this phone literally yesterday, it's unrooted, worked perfectly fine until my hand slipped when installing an icon pack from the play store and I hit "Open" - the phone immediately crashed, and now will not boot. I've tried using standard power on, powering on through the recovery bootloader, and entering recovery mode through said bootloader, in every instance it displays the Motorola startup screen, plays through its sequence of animations, then as soon as the Lenovo brand icon shows on screen emits one long pulse of vibrate and then turns off again.
I can't pull the battery because I don't have the required micro-hex screwdriver. Can anyone help?

can you reboot to bootloader and start recovery? Then clear cache and see if it helps to boot your device? Or if not make a factory reset if it won't help. Maybe the icon pack screwed up something.
Report back. After that, if nothing worked, you can try this:
Is your device recognized by fastboot? If yes, try "fastboot devices" and see if it shows serial number.
Then try to flash the latest stock in the following guide rom if you have one of this devices https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138

Hi, thanks for responding. After four or five attempts to boot into recovery it succeeded; wiping the cache did nothing so I did a factory reset, which worked and now the phone will boot to the setup stage. Unfortunately now I'm getting "The device was reset. To continue, sign in with a Google Account that was previously synced on this device.", which after googling seems to be a security feature - the problem is it doesn't accept the google account credentials, every time I enter them it just cycles back to the "This device was reset..." screen again.
I know I'm not getting the details wrong since I made the account specifically for the phone and have the details written down. Any suggestions on how to proceed?
EDIT: Actually nevermind, I managed to follow along with a tutorial on how to bypass it using MotoService & ADB. Thanks again for replying.

Recovery from bootloop (and other issues)

Ok, so... this is gonna be quite long to tell, but I need to explain the situation as carefully as possible because the problem I have seems to be very specific and potentially solutionless.
So, a week ago my Samung Galaxy Tab S6 Lite (SM-P610, CSC: ITV, which is the Italian Country Code and it's for unbranded devices, since my model is Wi-Fi only), suddenly started to restart itself and it's been stuck for days in a bootloop (i.e. it's stuck on the logo and if I hard restart it with Volume Down + Power, it gets stuck there again). Yesterday I found out that it's most likely a software problem, so re-installing the Android version should fix everything up... right? Well, I did just that but the device is still stuck on the bootloop.
Here I want to be more detailed: firstly, I'm 100% positive that the problem I have is NOT due to a virus, as I've never done ANYTHING that could potentially lead me to taking a virus (such as downloading apps outisde Google Play, visiting risky sites etc.); secondly, I followed a procedure that was supposed to repair my device without losing data. That's because I've stupidly never made a backup and I can't afford to make a factory reset. The procedure I followed consisted in finding the Android update I needed with Frija, and then downloading everything in the tablet with Odin. Also, I'm 100% positive that I made NO mistakes during the installation procedure. The only step that I did differently is HOW I installed the update: I did it with Download Mode, not with fastboot, because when I go into Recovery Mode and reboot the device into bootloader, the PC doesn't recognize my Tab, even if the PC does recognize that it's connected, as it makes the typical sound of when you plug something in a USB port (I have the USB drivers installed in my PC, I think it doesn't work because I never unlocked bootloader). What I get when I reboot into bootloader is "entering fastboot..." stuck screen and the PC and Odin aren't able to recognize it.
My questions are therefore these:
Is there a way to make a backup of the data of my device if I can't boot it (maybe via Download Mode)?
Is there a way to make fastboot work if I can't boot my device?
Is there some other way to repair my tablet that I can try?
Thank you for any help, this is my last hope to find a solution for my problem.

When your device is stuck on an Android boot loop issue then you can fix it by simply doing a soft reset. Turn off your device and the problem will be resolved.
Here are the steps to follow:
First, switch off your device and take out your battery from the phone.
If your battery is non-removable then turn off the phone for 3 to 5 minutes and again turn it on.
This method works effectively to fix the error of the boot loop issue. But if a soft reset does not work for you to fix Android phones stuck in the boot loop issue then you should follow the next method.
Method 3: Reboot System in Recovery Mode​Rebooting a phone in the Recovery Mode is known for fixing several errors and issues on your Android phone. So, if you are unable to start your phone in normal mode or your Android is stuck in a reboot loop, then restart your phone in Recovery Mode.
Method 4: Remove and Reinsert SD Card​You may also try to remove the SD card to fix the boot loop in Android. According to several user reports, this trick worked for them. So, you should try this.
First, turn off your phone > remove the SD card > turn on your phone normally, and check if your phone is out from the boot loop or not.
If it is still stuck in the boot loop, then go for the other solution.
Method 5: Reboot the Phone in Safe Mode​This problem may also occur due to problematic 3rd party apps. If you have recently installed an app on your phone and then you started facing this issue, then remove it from your device.
Or, if you are not sure which app is responsible, then try rebooting your phone in safe mode. Doing this will disable all the third-party apps on your Android phone and then you can easily find out if this is the reason behind this issue or not.
To do this, you need to follow these steps:
Start rebooting your phone.
When the device logo appears on the screen, long-press the volume-down button at the same time.
Now, your phone will automatically switch to Safe mode.
If your phone is no more getting into the boot loop, then it means one of the third-party apps installed on the device was causing this issue.
Now, find out the problematic app and uninstall it to fix the Android boot loop without losing data.
Method 6: Use Custom Recovery Mode​When you find your Android is stuck on the startup screen due to the boot loop issue, then you must try to restart the phone in the Custom Recovery mode. Here is the guide to do so:
To enter into the Custom Recovery mode press the Power + Volume down buttons simultaneously.
Select the “Advanced” option in the Custom Recovery menu.
Next, choose “Wipe Dalvik Cache”. Choose “Yes” when prompted for confirmation.
Move to the “Mounts and Storage” option and choose “format/cache”. It will clear the cache files completely.
Restart your device.
Method 7: Fix Android Bootloop Error Via CWM Recovery [For Rooted Phone]​Maybe you are not aware of this method but it’s a useful way to fix the boot loop issue on Android after the update. Remember that this method is only for rooted phones. Here CWM means ClockworkMod and if your phone is stuck on the Android boot loop then it must be downloaded and installed on phone. Read me

Thanks for replying but I already tried every method listed here.

At this point it sounds like you need to bring it in to a local repair shop & see if they have a fix.

The solution is to wait on the turned on screen until the battery dies completely. Then put it to charge and after a bit using the reset combo (pwr+volume down) once the circular battery charging indicator with the green border comes. (It's a matter of luck, this keeps happening to my tablet and even the official samsung store can't fix it even though they took money to do the same)
