Touchscreen not responding, cant turn on USB debugging! - Nexus 7 Q&A, Help & Troubleshooting

I have been using the Glazed JB ROM and was loving it but for some reason after 'allowing' Tasker in the accessibility options my N7 is stuck and does not respond to the touchscreen except to unlock from lockscreen. Literally I can boot to Android but cant do anything!
Worse thing is that when I power off it just reboots so cant access CWM recovery and USB debugging is off so I cant connect to ADB!
How the hell can I get to the recovery screen so that I can wipe & re-flash the ROM?
Please can anyone suggest something?
Thanks

Phew - just after writing this cry for help I worked out you can get to recovery from Android the same way as when the device is off - by holding power on, volume up and volume down. Thank ****!

If you can't do ANYTHING, then I would first suggest booting into recovery mode (Vol Up, Home + Power) and factory resetting and wiping cache, if that still doesn't work, boot into download mode (Vol Down, Home + Power) and flash a new ROM of your choice.
I have one of those phones that doesn't support 3-way solution for booting into bootloader or download mode :S
the phone boots up and i can unlock it, then the only things I can do is is slide down the notofication tab and see notifications and also switch wifi-bluetooth-GPS-vibration on and off :S
nevermind, I don't know how but I got the unistaller app up and successfully uninstalled the app, so now my phone works again =D

[Q] Really need help stuck at recovery screen

I just reset mytouch 4g phone and during restart the recovery screen just come out but I can't move down or up anything on the screen it just stuck..
I just update cm to version 3 of something
please I really need help on this my phone is already S-off
when I plug the phone with USB it response something by HBOOT has changed to HBOOT USB PLUG
I use Stock Rom just update Kernal only
Need more specifics. "3 of something" is too vague.
If you flashed clockwork mod recovery 3 (the text is orange) while using a stock ROM you will have issues. Clockwork 3 is for gingerbread based ROMs only.
If that is so, download CyanogenMOD 7 RC1 and try to flash it. Rebooting may help get recovery working right again. If not, and you are unable to re-flash a ROM, you will need to use fastboot to re-flash a good recovery image.

In clockwork you use the trackball to navigate. Volume buttons won't work.

Your attached image is of the Bootloader, not CWM Recovery.
The Bootloader is controlled by volume up / volume down to move between selections, and the power button is used to select.

You might see if the Bootloader can communicate with fastboot on your PC. If so, you will have options for un-bricking from your PC.
See http://forum.xda-developers.com/showthread.php?t=928370 for info on installing adb and fastboot to your PC, and using them.
Fastboot is designed to communicate with the bootloader. As far as I know, however, adb requires a functioning Android or Recovery system.

One more question, after following your advice, I found that I now can restart my phone again but when I shut down the phone and turn it on again it still stuck on bootloader screen all the times...any suggestion would be appreciate...
You can "restart my phone again" -- is it running Android at that point? If so, you can restore your phone to stock, and do a full factory reset, by putting the P15IMG.zip file on the root of your SD card and rebooting. The bootloader (if it is functional) should find it and begin the restore procedure.
Dowload, rename this, and stick it on your SD card, and reboot. If after a successful return to factory defaults, your phone still isn't working, the problem is likely not software.

boot loop after trying to flash twrp 2.2.1

Okay so I seem to have run into a little problem I was planning on updating cleanrom up to 1.2.5 but was on cwm. I had managed to switch over successfully to twrp 2.2.0. I went ahead and used goo manager to download the updated zip of 2.2.1 and tried flashing it thru twrp. Now I am stuck in google bootloop and cant get into recovery or more importantly bootloader. I have been trying last 30mins to hold power and both volume buttons but it either keeps rebooting back to the google screen or not doing anything at all just have to repress to to turn it off but it will turn back on automatically. I tried hooking it up to my usb and labtop but it looks like it wont even recognize it. I just fully charged it so I am good for now just a little worried cant get out of this mess.
I ran into a problem like that with clockwork recovery it kept on rebooting in recovery but I could still go into download mode I was at work away from my computer so I had no choice but to keep trying that three button magic until it finally restored a backup I had on my external card.just keep on trying to pull the battery then try to go into recovery. You might 've gotten a bad download

problem is I cant get into recovery. or the green screen to get to bootloader. It just completely stuck in a bootloop on the google screen mocking me... I am really contemplating opening it up and taking out battery but is that a good idea? Or is there anything else I can do?
so I pulled off the back cover but really dont want o disconnect the battery might mess something up but I cannot get the device to shut off.
disconnecting the battery does nothing it shuts it off and keeps it off but when I connect it to the charger the battery symbol pops up for a second and then goes completely blank. I went ahead and tried again to boot into bootloader pressing power vol up + down and all combinations of power vol -, power vol +
power turbo press vol +/- but no luck still in google screen.
If you're in a bootloop you need to connect your Nexus 7 to a computer. Then you will be able to access recovery via the Power button and volume buttons.
is it going to make a difference that everytime i try to reboot it just the black google screen? I have tried it connected to the wall charger and connected usb to the labtop but nothing.

It's supposed to do that when you're trying to go to recovery from bootloader without the USB cable plugged into a computer, may need to have the drivers installed on said computer. It's an issue with the nexus 7 bootloader and every one of them does it. What your experiencing is perfectly normal if you tried to go to recovery from bootloader with the bolume buttons and then got the google screen bootloop.
If it doesn't work when you plug it in and try, then try unplugging it, manually rebooting with it plugged in first, or vice versa
Update: I can get on Team Viewer and remotely reboot you into recovery through the PC if you want, or at least give it my best shot.
ok so i disconnected battery and have the device off. I should then try connecting it to the pc and try booting up holding down all buttons?

Have you installed the right drivers on the computer you're using, for ADB and the device drivers, when you unlocked and rooted?
Answer to your question is yes try that. But I wouldn't be disconnecting and reconnecting it, I can't recommend that and then learn tomorrow that static zapped something important.
yea I am getting nothing by connecting to pc. I have all the drivers adb and fastboot installed when I rooted and unlocked couple weeks back but it looks like device is not being recognized or read at all by the pc.
connecting to the pc holding the volume + button gets it recognized for a second and tries to install a driver apx but unsuccessfully.
I am not making any progress whatsoever kinda sucks starting the weekend like this. I have gone thru some bad stuff with my atrix but nothing like this were I cant even access my bootloader boot into recovery or even fastboot. Should I try and get it to just stay off and see if overnight it works its own magic? Hate going to sleep witht his on my mind but I think with a clear mind in the morning something good will happen.
I can get it to stay off by holding both vol+ and vol- but trying to turn it off with just the power button just keeps it turning back on/off...
so I slepted on it thru the night let the tablet rest but went back this morning and I still cant get into bootloader or recovery. Is there anything I can do?
Has anyone else had this problem where they cant boot into recovery or bootloader? It's like the power button and vol keys are unresponsive even though they still work to turn on the device.
are you sure that you flashed the right recovery? but you should still be able to get the bootloader. are you pressing power + volume down(volume down, not both volume buttons. i noticed you wrote both volume buttons) to get into the bootloader?
I think I chose the right recovery the first version downloaded thru goo manager but it was the 2.2.0 version. I had the option on the of downloading the 2.2.1 zip or the .img but i downloaded the .img to just to flash with the current version of twrp that was working. There have been times were I have not been able to get into recovery on my atrix or htc but I've always been able to get into the bootloader this is the first time I've been locked out of my device kind of got me scared its not even a month old. So you say to get into bootloader you dont have to hold down both volume buttons? I will try again to power back up using the volume down and power button at same time... Wish me luck

quick question before I connect the battery does it make a difference whether or not I have it plugged in charging or connected to the PC while trying to boot into bootloader?

[Q] Nexus 7 Stuck on cm10 Start Up Help!

Okay so i was watching a video on youtube on how to get cm10 on my nexus 7, i bought the nexus 7 off a friend who rooted it for me and he had clockword recovery or whatever you call it set up on it. So the video said to download rom manager and then i went to download and downloaded the stable cm10 with gapps. Then it rebooted and what not and now its been stuck in the cyanogenmod spinning circle start up for about 2-3 hours now. So i held the volume and power button to get to the fastboot thing and shut the nexus off and then i restarted it and then.. the google sign came with the unlock icon and then the cyanogenmod circle came again -.- Please help if you can, sorry if any of this doesnt make any sense im new to all this. Thankyou in advance.
Power off fully, then hold the Vol+Pwr buttons down until it goes to the fastboot menu. Vol down to select recovery. I would do a factory reset and reflash the ROM + gapps.

Yea i did that right, it goes into the fastboot menu and i go to recovery mode. And when i click the power button, all that happens is that the black screen with google and the unlocked logo show up, and it stayed like that for like 2 hours again -.-
Do you know why that happens?
If you reflashed the rom I'm guessing a bad download.
ETA: Did you make a nandroid before installing? If so restore that.
Oh okay. So u suggested to do a hard reset. How exactly can i do that? My nexus wont load past the load up screen, on some occasions it goes past the google and unlock logo but then a cyanoggenmod spinning circle thing comes and then that just stays there.
Go to the bootloader (vol dwn+pwr), and plug into computer. Then select recovery mode.
Do a factory reset from there. Then reinstall CM10.

Oh okay, actually im really glad u just said this because i just tried this way. I powered off my tablet, then turned it on with vol dwn and power to get into the bootloader. Then i plugged my tablet into my laptop and now the volume keys wont let me scroll down to recovery mode. Pretty much the volume button becomes useless to scroll. Any help?
If the Vol buttons aren't working I'm out of ideas besides: try again? Otherwise you're going to have to wait for someone smarter than me. Sorry.
ETA: Found this guide: http://forum.xda-developers.com/showthread.php?t=1907796 Maybe it'll help you.
wait do i have to have the latest drivers for nexus 7 installed on my pc b4 i plug it in? If you do know, let me know where i can find them. If you dont no worries ill wait for someone else, thanks for your help so far.
Hey don't know if you got your Nexus working again but I saw this thread about the buttons not working. Not sure what version bootloader you have.
http://forum.xda-developers.com/showthread.php?t=1840675
Make sure you wipe the Cache and Dalvik Cache!!
When I first flashed CM, I got the infinite boot animation as well. I rebooted into recovery, did a wipe of my caches, and it was fine from that point on.
Also, when going from one rom from another, you gotta do a factory reset if you didn't already.
Yea I forgot to clear all the data.. nvr again but I can't get into recovery thats the problem. I have the 3.34 bootloader and it doesn't go to recovery and I tried plugging into my pc and then the volume rockers become useless. Any help plz?

I had the same problem this morning. After about an hour of messing with stuff I used mskip's toolkit to uninstall then reinstall the drivers. I
then rebooted into the bootloader without a cable and then connected the cable and the buttons were still responding. After that I updated
the bootloader to the latest release and I was about to boot into recovery.

[Q] Can´t access fastboot

Hi,
I rooted my N4 and instaled CWM and CM11 but after instaling gapps my GUI go complete crazy and turn black. I can ´t get to settings but I can start apps from lockscreen shortcuts. When i tried go to bootloader or fastboot it didnt work and I cant get to them in any way. So question is how can I reinstall the ROM or fix CMW? I tried to connect to ADB but whitout possibility to accest setting I cant get device found.
Thank you a lot
Can you boot your phone into the bootloader? And if so does your pc recognize the device? I'd the issue with your phone or the pc recognizing your phone?

No I cant get into bootloader or fastboot (power-vol) but system starts normally except i cant get into settings or applications menu because it crases instantly. My PC recognizes the phone and i can put files in phone. I have probably turn of USB debugging and cant find phone in ADB.
Thank you for response

Can you boot into recovery from your system, or does it crash too soon? If you can flash a nandroid backup
Sent from my Nexus 5 using XDA Free mobile app
No basically I start to a system and have black screen. Only things I can start-up are apps on lockscreen shortcut and top panel (contacts,flashlight,GPS, calendar).
If your phone is booting normally and you can't access bootloader then either your buttons are broken or you're pressing it wrong.
Turn the phone off completely then hold both volume up and down together then continue to hold them while pressing power until it vibrates.
You were right Easyiest way is the best way! I disassembled the phone adapt the buttons and now it works perfect with bootloader etc.
Thanks for remind me other possibility
