[Q] Cannot enable USB Debugging - Nexus 7 Q&A, Help & Troubleshooting

My Nexus 7 freezes and reboots whenever I attempt to enable USB debugging
Am running Android 4.2.2.
Have tried factory reset option (twice) but problems repeats.
Very annoying. Any thoughts?

Try reflashing a stock ROM into the system. Do a full wipe first.

Have you followed the sticky up top that says how to flashing a stock ROM/factory restore. Or similar verbiage. There are fastboot commands that will wipe everything and literally make it like the day it came out of the box. If still having an issue then odds are you have some sort of hardware issue.
Also don't try to restore or install any apps after the restore. Enable developer mode first then add away. Perhaps it's an app you're installing that's breaking things.

[Q] Rooted, CM 10.1, clean rom, now stuck...need help!

Hey, I could really use some guidance here. I'll present the information as simply as I can:
I bought a Galaxy s4 AT&T a few days ago. I've been interested in rooting and flashing different roms, but I think I may have done a bit too much.
I rooted using the motochopper method - great, worked like a charm.
I made a backup of my original rom using CWM. I even took that backup and saved a copy of it on my Mac - perfect.
I thought I'd try Cyanogenmod 10.1, so I downloaded the latest nightly build and flashed it using CWM - so far so good.
Everything was working fine, but my LTE (or any data) was not working at all. I could use Wifi, but once I turned wifi off, I had no data, no gps, no 3g, no 4g, no LTE. I tried the *#*#4636*#*# method, the LTEOnOff app, and changing my APN based on the recommendations provided in this thread - I just couldn't get it to work.
I thought I'd try restoring my original backup, but when I went into CWM to do so, it said that my backup could not be found...(I still have a backup on my computer, just in case)
I needed my phone to work, and badly needed LTE to do so. So, I downloaded this rom: [ROM] CleanROM 1.0 -★| Clean and Smooth! | The Way Nature Intended! |★-
So far, this rom was working fine - it's just a debloated version of TouchWiz - which I like. But, here's my problem now - If my phone reboots, it stays frozen on the Samsung logo (with unlocked lock logo underneath), and I can't get past it. I'd have to go BACK into recovery, and flash the CleanROM all over again, and set my phone up as new with all data wiped.
I really need my phone to work again, and I don't know where to go from here. What options do I have left? What can I do to get out of that frozen Samsung loading screen? Can't I just reset my phone to the way it was? Can't the CM10.1 rom work with LTE?
Your help will be greatly appreciated.
Your best option is to flash the stock MDB firmware via odin . After you get the PASS on Odin go ahead and manually boot into stock recovery and wipe data factory reset again then reboot. You will have to re root and reinstall recovery but this will take care of any issues you had from a bad flash.

Having the same issue so I figured I'd give these steps a shot. Followed them exactly and phone (AT&T S4, TWRP) would won't even reboot the first time into CleanROM. I'm stuck on the Samsung screen with the lock.
edit: I've noticed that now, when I reboot into TWRP, it prompts me for a password. Hitting cancel takes me to the regular home screen, but I had not been getting the password prompt before attempting to install CleanROM. A permissions issue, perhaps?
edit 2:
I've just spent some time trying a bunch of things with bits of good luck surrounded with tons of bad. Below are the steps I've taken to try to get CleanROM to boot (and reboot) without any issues. Hopefully they help figure out the issues we're having.
Wipe Cache

I can't speak for OP, but I was hoping there was another way to rectify what has already been done without flashing stock seeing as how I'm on OSX. If that's the only option, then so be it.
Hey. Thanks for the feedback in this thread. I flashed factory through Odin, and everything is working fine. I then factory reset my phone through factory recovery. I'm back to standard touchwiz with all the bloat lol.
I'm going to wait until there a more stable release of cm10.1 - that was a good rom.
Appreciate all the help people!

Your best bet is do what "cataligh" mentioned... flash back to stock via odin...

When you flashed cm10 it probably wipe the internal sdcard, you should ALWAYS do you backups to the extsdcard...period.

As I mentioned before starting over is always the Best and Safe way to go. Shortcuts will only cause you headaches and possibly get you a brick that is why you see Odin stock threads. Do yourself a favor and start over I know it sucks but when your modifying your phones its gonna happen once in awhile.

Yeah, data was enabled - and I was using ATT LTE apn settings that I found on these forums. I made sure to use the right now. Plus, when I rebooted my phone, it got stuck on the Samsung lock screen again...

Yes, those were the exact settings that I used. Is it possible that I could have a defective phone or sim card?
Right now, I am on factory touchwiz with root enabled, and my phone is working perfectly fine. I can reboot, use LTE, everything. The problem starts when I load any CM or AOKP rom...

[Q] CM10.1.2 Bootloop

I was having a ton of problems with my Nexus 4, like i mean a TON
so I decided to just fix it and factory reset my phone. I rooted it with the nexus 4 tool kit and flashed TWRP. I found the CM10.1.2 zip and the 4.2.2 GAPPS. Flashed the ROM, then the GAPPS, then cleared both caches and Rebooted my phone. It is stuck at the spinning CM circle boot logo forever (I even left it on all night). I tried flashing CM10.1.0 with the 4.2.2 GAPPs same process and still in a boot loop. WTH is going on. I'm so frustrated. My phone was wiped clean and the only app I have is a file explorer besides the preinstalled Google apps.
Help.
I made a backup of when I freshly rooted my phone so I don't have to keep rooting when I enter recovery to get away from the boot loop
Before you flash the ROM did you do factory reset? Go into twrp do a factory reset then flash ROM and gapps then reboot it shouldn't take more then 5 mins for it to boot

I answered your post. The point of XDA is to share development work and learn how it works but if you're using a toolkit and not reading you'll never learn that's why you've had "a ton of problems" and don't know how to fix it

Sorry I never saw your reply. Thanks for replying. I did a factory reset from the settings menu NOT from within TWRP. And the toolkit is not to blame because I've used it plenty of times before and has not caused any problems. All it does is root my phone.
Umm you need to wipe within twrp before you flash. You're bootlooping because you only did a factory reset which only deletes cache and stuff. Wipe from within twrp and then flash

I wiped from within TWRP, rebooted and then my attenas were not working again. I could at least see the networks in my area but I could never connect on WiFi- it kept saying "Authenticating". It also said "No Service" for my 3G.
I booted back into TWRP and went into the advanced options for wiping and selected everything besides some "usb" thing and I think I deleted my OS -__- . I'm an idiot I should really not do what I don't know. I'm just going to flash stock ROM (4.2.2) with the Nexus 4 Tool Kit and see if things improve.
Thanks for your help.
In twrp if you're flashing a different always do the advanced wipe in order to clear the previous rom. Doing the basic wipe in twrp has the same effect of factory reset from earlier

[Q] Problems after wiping User data

I thought it would be a smart idea to wipe all data on my Nexus 7 before selling it. Now it reboots to "Unfortunately, Setup Wizard has stopped." i have tried to wipe data/factory reset it in the recovery mode, but that did not work. does anyone know how to fix it?
Just wipe everything and return it to stock with Odin, or fastboot. If you're selling it and have anything you want transferred off it...wipe internal sd also.
Just make sure you read a guide and know what your doing.

Do you have a custom recovery or is your tab stock?
I know this is probably more work than you were wanting to do, but this is a good guide for flashing the stock image and returning your nexus 7 to stock, or recovering from a boo-boo.

Yes i have ClockworkMod Recovery. I'm not sure if i have USB debugging on, it does not say anything when I plug it in, and I am not able to activate it, since I'm locked out.

If you try to flash a new image I'm pretty sure USB debugging doesn't matter because you are in fastboot. Most likely you need to update your drivers and the SDK. The link above has a section on "driver hell" and solutions for it.
In ClockworkMod have you done all the wipes along with the factory reset? If so, I think you will have to reflash.

Are you rooted? If so and you have a custom recovery, I would do the factory reset via the recovery, that way you should still have your apps. If not, then you will lose everything and have to start from scratch.
Could be due to one of two things or a combination of things. One is a hardware issue, which I hope isn't the case. I would check the apps first before resetting, then do the reset. If it continues, try re-flashing the stock image. If after that and you're still having problems, going to 4.4, or 4.3 since it started with 4.4.

If you flash stock, it WILL wipe out everything unfortunately. If you at the least had an unlocked bootloader, you could have flashed the ota.zip and kept everything intact.

[Q] Nexus 4 is being really weird

So I've decided to switch to a more stable version of PAC, and when I flashed it on top of the latest nightly, things got really weird. So I decided to just reboot, wipe, and flash again. This time when I flashed it, it would go through setup but a dialog box would insistently pop up saying "system.android.phone has stopped". So I decide it must be a problem with PAC, so I go back, wipe, and flash Purity. This time I can't even get a setup wizard because a dialog box says that the setup wizard has stopped. What should I do? Should I just format everything and go from there? Thanks!
Yeah, that would be your best bet. Flash the factory image and start fresh.

Hm, I don't know then. Are you flashing anything else while/after flashing the ROM? You can flash a Gapps package after flashing the ROM before booting, but you really shouldn't flash anything else until you boot, load everything, then reboot.
Okay, so you're going to have to go into fastboot and plug your device in and navigate to your platform-tools folder in CMD and try
fastboot devices
to see if it recognizes your device. If it does than you can follow the instructions around here on XDA to flash the factory image onto the device. I think all you have you have to do is click on "flashall.bat" or something like that and it will flash the entire stock image to your device.

So I tried flashing Purity again and wiping system, without flashing Gapps and it worked. But when I flashed gapps, this constant dialog box saying setup wizard has stopped came up. What should I do? Just start from a clean slate?
