Strange (software?) problem

I'm new here, so correct me if i'm not on the right place to post this.

I have a nexus 7 32gb wifi edition. And i have a touchscreen issue (software I guess). I have seen many posts of people having touchscreen issues, but not something like mine. When i wake up my device, it's totally responsive (no irresponsive spots), but when i lift my finger and want to touch it again, it doesn't respond to anything anymore. This is everytime i activate the screen, everytime i can touch it once before it becomes completely irresponsive. Is there something I can do to fix this? I am pretty sure it is a software issue, so it should be fixable, right?

Thanks

If you aren't rooted, I'd be doing a factory reset.
[Nexus 7 Q&A, Help & Troubleshooting] herman102:
Did that, didn't work, then i rooted so i could figure out more. Didn't find anything, so i guess i'm stuck.
[Nexus 7 Q&A, Help & Troubleshooting] TheAtheistReverend:
Sorry to hear that. That is strange, but sounds like it would have to be a hardware issue.
[Nexus 7 Q&A, Help & Troubleshooting] herman102:
I don't get it. If the touchscreen works everytime I wake it up for only the first time, it means it won't recalibrate fot new input, right? So how can it be an hardare issue? And if it is, will it be fixed when i buy a new screen for it?

Hi, I've wiped the system in TWRP and I'd like to flash a stock rom, my problem is that my PC won't recognize the Nexus. So now I can't copy a rom on it and I can't even push it with adb. Any advice what should I do?
[Nexus 7 Q&A, Help & Troubleshooting] Anderson2:
I'm no expert but it is often a driver or cable problem. So here are some suggestions :

1. Make sure you are using the oem usb cable that came with the nexus. It will have Asus stamped on one of the end

2. Make sure usb debug is turned on.

3. Try setting the usb connection to mtp selected or unselected.

Hope this helps.
[Nexus 7 Q&A, Help & Troubleshooting] Pr3no:
I use the oem usb cable, and all the drivers are installed. I'm not sure if usb debugging is turned on and I don't know how can I turn it on from the recovery. I also don't know how can I change usb connection to mtp from recovery.

Edit: now it looks like I've got it to work.

Would like to pass on my original nexus 7 to my daughter

Hi guys! I just picked up a Nexus 7 lte and would like to pass on my original Nexus 7 to my daughter. I have it on twrp 2.4.x? It is unlocked and rooted.

I flashed 4.3.1 with AOKP version buttered grouper JB mr2_2013-10-25. I have a copy of the twrp file from the sd card with BU's on my computer- it has the original stock BU and the new custom rom BU.

I would like to factory reset and wipe all user data- but want to leave the rom and custom recovery. So it is like new, OOB. She can set it up from scratch.

I was about to format data in twrp, but decided to double check here. Will that do it?? If I have to put back the twrp file, that's no problem.

Thanks in advance for your help.

Hey, I have a problem. I have the first nexus 7 and I unlocked and rooted it with the nexus root toolkit. The tablet is damaged and I was thinking of sending to insurance to get repaired. Now my problem is that when I turn it on it on it boots up but goes to lock screen and as soon as you touch it it makes a wired sound, then the screen goes crazy and finally goes black with small static dots. Now I tried to restore it to factory image with the nexus tool kit but I can only get to fastboot but it will not allow me to do anything because the adb is not enabled,and so is there any other way to get it back to stock and lock bootloader so I can take it to insurance , I heard maybe Odin but haven't found anything so could someone please help! Or at least point me to somewhere that can.

Thanks..

my nexus 7 not booting up plz help!
[Nexus 7 Q&A, Help & Troubleshooting] sashusmom:
Found my own answer and thought I'd share: What I wanted to accomplish was to keep custom rom and recovery, but wipe everything so it is like new out of the box. But it removed my twrp! or it didn't! I used wug's toolbox to see what was up and it updated my twrp so I guess it's still there.

It's still there. It just doesn't go right into it. You get the Green boot loader screen, and you have to select with volume buttons recovery, the hit power to go into it. I don't remember that a year ago. I had flapps power tool to boot into recovery.

From http://www.addictivetips.com/android/what-is-twrp-how-to-install-use-it-on-android-devices-guide/

Lots of great info on using twrp!

"If you would rather want to wipe EVERYTHING including the aforementioned data, tap ‘Format Data’. This will wipe all your apps, backups, downloads, pictures, videos and media, and will also remove encryption on your internal storage, if you have applied it, essentially leaving nothing but the operating system itself on the device, in a complete factory state."

Can someone please help me! I need to factory reset my Nexus 7 without root. And lock bootloader! But I can not keep it on.

I can plug it in and it will turn on But as soon as I open the lock screen it makes a weird sound and shuts off. Now I can get to fastboot mood and it will stay on somehow. But I don't know how to do anything without the adb debugging not being on . I don't know what I can do can someone please help me!

Thank you.

What about Wugs toolkit? That lets you do a ton of stuff. All you need to do is make sure your drivers are installed properly ( the toolkit walks you thru it) and it practically runs itself. Give it a try.

it seems that I have some modules missing and I cant seem to loop mount the factory system 4.4 img to grab the modules.(It says it doesnt know what filesystem it is but it wont except ext4 as a filesystem either.

I ended up just flashing the android 4.4 system img from fastboot but can anyone shed some light as to why this is happening?

You can check out my ota zip at ftp port 21 on jacobs-elec.chickenkiller.com

it has no password

it has the patch check lines removed because I have removed some apks and It has all of the new google apks removed.

[/COLOR]I currently have what I hope is a soft-brick. I had my Nexus 7 rooted and running a custom kernel (Franco) at one point. Got the new N7 and passed 2012 model down to my wife. First, I did a factory reset, returning completely to stock. However, I noticed SuperSU was still installed. Since bootloader was locked and everything stock, I didn't think much of it.

Just tonight, the 4.4 OTA downloaded and I hit restart & install. The process went fine until right at the end of progress bar, and got an Error! message. I rebooted, but it is loops twice after showing Google logo, then I see a screen that says "No Command". I got into the bootloader options and hit the Wipe Data and Factory Reset option. Data was wiped, but same thing happening. I did NOT have USB Debugging enabled prior to this. I tried sideloading via adb, but I'm guessing since the debugging was not enabled, it did not work. All toolkits require this.

My question is, is this tablet now a brick? I can't think of ANY way to fix it. I can't get back into the system at all to enable USB Debugging. Any ideas or should I use this as a coaster now?

Can you get into fastboot? If so, you can still flash the factory images with fastboot and the SDK. Never used a toolkit so no help there.

I use this manual from androidauthority.

However, if on the video on step 6 the display fell off easily, I can't do this. Under the battery and on the right up corner something holds the screen and the motherboard. These are red and green zones. And on the yellow zone I have, I guess, a power cable, it is on glue too.

Nexus 7 root from unlocked bootloader

I recently had problems with my N7 updating to 4.4, where it crashed and bricked, so i wiped, and used adb sideload to flash stock recovery and rom, and i think in the process i unlocked my bootloader (shows a unlocked padlock on boot now). It it still a case of to root, a wipe will occur, or not, as i have unlocked the bootloader? Many thanks.

Unlocking the device is what does a full wipe. From here you can get a custom recovery and root now or later without a full wipe again.

Problems

CPU spiking

I think it's borked!

I've got an unusual problem. At least one I haven't come across here yet. I figured I'd finally try out 4.4 but was running TWRP and everything I've read said I should use CWM, I successfully switched to CWM, flashed CM11 and was fiddling around for a while.

Eventually, the screen just flashed and everything powered off. I tried booting normally, booting to recovery and booting to the bootloader but none worked. Somehow TWRP came up in recovery instead of CWM. I then plugged it in first to the wall then the pc. Both got it to turn on to the bootloader but before I could really do anything, the screen flashed, went black and had what looked like fine static. Same thing happened when I booted to TWRP. Kinda like the old black UHF channel that wasn't picking up a signal. It basically stayed like that until I powered it down.

I obviously screwed up somewhere along the line but don't know if it's fixable.

Has anyone experienced that before?

Anyone know what happened?

Is it something fixable?

Stuck in recovery, can't mount USB

Hi! I'd really appreciate some help as I'm pretty stuck.

I had CyanogenMod 10.1 on my tablet, installed though their very fancy new app. Yesterday I got a auto update notification. After installing the update, the tablet got stuck at the startup screen (CM logo cycling endlessly) after I typed in my decryption code. Rebooting doesn't help so I tried booting into recovery. I have CWM 6.0.4.3. Of course I had forgotten to save a recovery image, and I can't get the tablet to mount USB storage. In the device manager the tablet is listed as ADB Interface, but adb.exe does nothing. The window flashes though some code and disappears again in about a second. I tried formatting and wiping everything I could find, as well as a couple different driver packs from Android SDK and Asus, but there's no difference. I can't get USB storage mounted. I'm sure I must have messed up somewhere but I'm not sure how.

My main problem is that I can't get a new zip onto the SD card at this point. If I could I should be able to flash a new kernel and ROM and be ok from there.

Any help would be appreciated! Thanks!

How do I make a complete system ROM of my device?

Earlier I created a system ROM backup of my phone using MTK droid tools and used SP Flash Tool to flash it back. It created a complete system/data backup of my phone. Whenever I had an issue, or a flash went bad, I could restore that backup and come back to an earlier state no matter how big the issue.

[Nexus 7 Q&A, Help & Troubleshooting] VideoSavant:
sukiluv,

I have seen behavior with my Nexus 7 (2012) roughly similar to what you are describing. The app specifics are a bit different, but the general behavior is the same -- boots normally, goes to home screen loading/notification updating, freezes, reboots and repeats the sequence. I have posted about my issue here (just a couple of posts previous to yours) and elsewhere on XDA without any suggestions or fixes. A little surprised by the lack of feedback, but I do appreciate that my problem is pretty far outside the norm of what comes up with Android tablets. Like you, I suspect that there's a hardware problem, as I have tried the Nexus Root Toolkit as well as several manual fixes without any success.

Do post here if you find a solution and, of course, I'll do likewise. Good luck.
