General :: Rooted Nexus 7 WiFi (2012) Won't Boot After Attempted Kitkat 4.4 Update
Nov 27, 2013
I am trying to get a friends Nexus 7 up and running. I recently rooted it and installed the custom recovery using my Mac with this guide while the tablet was on 4.3. All was well, but then my friend was given the option to install the 4.4 Kitkat update. After the update, the tablet has been unable to boot - it simply hangs at the startup animation. I am able to enter the recovery boot loader, and enter options to restore from a .zip, however I have no way of accessing the tablet's memory from my computer to put the original operating system back on it- although I think it could be done from Terminal, I am not well versed in command prompts.

how to get my nexus 7 tablet to be recognized by the computer (I tried and after two days of searching for answers I decided to make a post). I like to include this information so people don't assume that I post without browsing or haven't tried anything yet.
The thing that I am having troubles with is that I have a nexus 7 tablet that is softbricked, I have already gone through a lot of ways to fix that problem (I found the best solution is this:[URL]. However, the issue is is that I cannot get my computer to recognize the nexus tablet to flash it and restore it back to factory settings.
I have installed and updated the device drivers on my computer, but still I have had no such luck. I found that ADB doesn't recognize the device whilst in the Bootloader, but still will not recognize the device in recovery mode.

I have a Nexus 7 running 4.2.2 Jelly Bean, with an unlocked boot loader and rooted. Since the 4.3 versions are now officially out, I was wondering how I would update. Is there any special process? Can I just use the normal OTA update service built-in? Will doing that lose my root and unlock? If possible, I'd prefer the most risk-free method, as I don't want to mess up my Nexus.

The WiFi on my Nexus 7, 4.4.2. Tablet is acting strange lately. It will randomly disconnect from the current internet connection, and delete the entire WiFi password/login history. I have to fill in the password again for it to work again. Restarting my device didn't solve the problem, and WiFi optimization is unticked.

on my Nexus 7 (Android 4.3). Via the reading history of my pdf reader (Moon+ reader) I can see that at least one file is still present in the cache under the following folder address:
[url].....
How can I access this folder? When accessing the device via the Android File Transfer sofware for Mac, I don't see this folder. I have access to Android/data/com.google.android.apps.docs/files, but this folder contains no files but only another folder (called "pinned_doc_files_not_for_edit") which is also empty.
The lost pdf is still there, I can open it in the reader via the reading history, but I would like to access the folder to see whether other lost files (which are not in the reading history) are also still present. To be clear, the file which I can open is also not detected when searching the device for pdfs.

I finally updated my nexus after seeing it in my notification column. All seemed okay so let it get on with it.But when I thought it was ready I cannot get further than the four moving coloured circles. I have tried to factory reset and delete cache but has made no changes. I have been in contact with google play who now say there is no more actions that can be done so will need replacement.

I've noticed my Nexus acting a bit buggy since the 2.2.1 update. Lots of force closes with the launcher. (which is exactly why I shredded and burned my old MyTouch for). After FINALLY getting a THIRD 16 gig card, after the other two got "damaged" costing me so far 25-30 gigs of content, I loading it up with movies and songs for my vacation. I go to reboot and it keeps looping the boot animation but wont boot up. Getting really close to kissing Android good bye as I've had NOTHING but bugs and damaged SD cards and an overall terrible user experience for a year and a half with two phones. I know we're only really two years into development but how much longer do we have to wait for a finished product that I don't have to keep making excuses for? More to the point WTF is going on with the boot loader on my phone and how do I fix it?

I connected my X10 to my computer two days ago and was prompted to perform a software update which I chose to do believing it would get rid of some ongoing issues I've been having with the phone
The computer found the phone ok, then PC companion prompted me to disconnect the phone from the USB cable, making sure the battery was at least 50% full (it was), switch off the phone and wait at least 5 seconds (waited 30), then plug it back into the USB while pressing and holding the "Back" key.
All of this I did according to instructions, and the information on the screen said it was downloading the update, but broke down and stated that an unexpected error occured during installation. I was prompted to try again, which I did, same thing happened.
At this point the phone just shut down and point blank refuses to turn back on. I tried removing the battery and putting it back in, nothing, I also tried to charge it thinking maybe it was drained during the attempted update (power surge?) and again, nothing.
When I try to switch it back on while it is not connected to a charger or the computer the light flashes red three times. When I connect it to the computer it turns green for a few seconds then goes off again. Currently it's flashing red every few seconds, but will still not switch on.
My biggest problem is - if I take it in to be serviced, will they be able to retrieve my contacts from the phone memory? A backup was done but I no longer have access to this either as I had to reinstall my computer system and this data disappeared (i have a bunch of empty SE folders on my backup disk)
I'm in Croatia and support here are very, very fond of flashing the software as the easiest way out and swearing blind there is nothing they can do to keep the data - if nothing else I'd appreciate feedback from anyone else who has experienced this problem and got their phone back with contacts intact so I can argue more coherently when I take it in to the store tomorrow
I honestly don't care about any of the other data than my contacts, the rest is replaceable, but I have no way of contacting a lot of the people to get their numbers again.

The 2.2.1 update was supposed to fix the problem that causes wifi to disconnect when my N1 goes to sleep. As far as I can tell, I'm still having the same problem and it might even be worse because I've noticed that sometimes wifi disconnects even when the phone is plugged in, which didn't happen before.

I have enjoyed my nexus 7 2103, on 4.4.2, for a few weeks now. I got adblockplus to clean up my browsing. My office wifi wasn't letting me ssh tunnel to my home server, so I set up hotspot vpn shield, but it limits usage in the free version. So I grabbed connectbot and proxydroid to get in, root using wugfresh to make those work properly. Got what I needed from the home server, shut it down, and headed for home.
So I got home, and Chrome now says Unable to connect to proxy server. So I made sure connectbot and proxyserver were not connected, and deleted the profiles I'd set up. No luck. Deleted the apps. No luck. Deleted the apps, no luck. Turned off ad block plus and deleted that, no luck. Cleared out hotspot vpn shield, deleted, nothing.
So I tried factory reset, no luck. Then I read that some people have had luck reinstalling those apps that changed proxy settings, which hasn't worked for me yet. I've tried restoring the backup I made preroot, no luck.
What can I do to get my nexus back online? I finally found the proxy settings under kitkat (totally different than older versions, you press and hold the network name, NOT intuitive). I'm back online, and will tell my self I'll be more careful in the future. But I won't be.

I recently bought a Nexus 7 Flo tablet running the latest Android 4.4. I've since been trying to spoof a MAC address on it, but for some reason the wireless card seems to refuse to use the spoofed mac no matter what I do.
There's a more detailed discussion what I've tried in android.stackexchange.com/questions/57922/wifi-network-not-accessible-with-modified-mac-address (forum won't let me link), but I'll repeat the main points here. I have tried both ip link set wlan0 address XX:XX:XX:XX:XX:XX and busybox ifconfig wlan0 hw ether XX:XX:XX:XX:XX:XX. They both result in the MAC address being changed as far as I can tell from the output of ip link and busybox ifconfig, but when connecting to a network with MAC filtering with the spoofed MAC address being allowed, the device fails to connect. /sys/class/net/wlan0/address also shows the spoofed address. If I use the device's stock MAC and add this to the filter on the AP, then the device connects successfully.

I'm on the Nexu5 and was wondering whether or not the permissions manager was reachable through Kit Kat? I've tried the usual permission manager / App Ops stuff from the Play Store and nothing seems to work. Is there a way to access it or did they take it back away with Kit Kat?

I can't understand why there is not an official Google Version. Why is it Apple with iOS 7 ships their phones with this option.
Yet it seems with an Android phone their is no official Google Support for Traditional Chinese Handwriting Input.
I am running a Nexus 4.

I have a Nexus 7 2012 wifi version that I have updated to kit kat. I decided to root it but there's no way, believe me I've spent a lot of time on it. No driver available (or at least nothing works). I need to roll it back to jelly bean, then I should be able to get the correct driver and root it. So here's the 64 thousand dollar question: How can I take a device that's already been updated to kit kat and install jelly bean on it?

My device details: SGS3 T999, rooted, running Jellybean 4.3 on a liquid smooth ROM. Its a year old and has been a solid performer up until now.
My device is stuck in a cycle where it gives a quick vibrate, then SGS3 splash screen with white letters, then black screen, then tiny blue "Recovery booting..." words in upper left of screen, then black screen with couple vibrations, and around and around it goes in the same repeating cycle.
Just before it started I had taken the following actions: Dumped the following 2 files onto my EXTSD card (cm-11-20131217-NIGHTLY-d2tmo.zip, gapps-kk-20131119.zip) from my PC, booted phone into recovery mode using TWRP, did a factory reset wipe (success), cache wipe (success), dalvik cache wipe (success), flashed the NIGHTLY file (failed), flashed the gapps file (failed). At this point I should have sought some support. Fool! I next did a reboot step still in recovery mode. Without the reboot happening a message came up stating Superuser permission had been broken (the best I can remember) and the option to have TWRP repair the permission. I opted "yes" to repair. Then the loop started that I can't escape.
I have pulled the battery multiple times, tried a regular boot up, tried a recovery boot up (up volume+power+home) dropping the home button after a few seconds. Nothing is working. Prior to the above steps I backed up everything on the device. So I have backups to use if it can be done. My best guess is that I failed to update my CyanogenMod or TWRP to the very latest versions and it caused this hang up.

Once you have turned on GPS, when you turn it off later, sometimes it doesn't really turn-off even if the quick setting tile says it is turned off.
[EXAMPLE]
I turned GPS on, opened Tinder, used it for few minutes, closed it and turned off GPS, removed Tinder from recent apps.
Next night, I see Tinder is the top battery consumer, with 1 day 9 hours of GPS use. GPS shows up as ON the entire time in the battery graph; while GPS tile is "off" in quick settings as well as locations services is also set to off.
[SCREENSHOTS]
I had seen exactly similar GPS hogging from Facebook and Maps too.
This exact same thing happens with Wi-Fi too. I had turned off Wi-Fi at night before going to sleep. But after returning from work the next day, I see in the battery graph that the Wi-Fi was on for the entire 17+ hours. And it still showed as "Off" in Quick settings tile and Wi-Fi settings page. The Wi-Fi definitely wasn't ON since as soon as I turned it on via QuickSetting tile, I got a flood of notifications. But there was considerable amount of battery drain, which is unusual when everything is off. Makes me think that the Wi-Fi was in fact ON. So, when I had turned Wi-Fi off at night, the phone only disconnected from the hotspot but still remained on.
[DEVICES]
Nexus 5 - running stock 4.4.2 with Xposed and latest Linaro.
Galaxy Nexus - running AOKP 4.4.2 nightly with Franco; no xposed.
[BUG TRACKER]
Issue #64998 - The GPS bug was already reported by someone else in the Android project bug tracker. But it has low priority there and doesn't look like it will get addressed anytime soon.
