I flashed Taboonay 2.1 to my Icona Tab A500 last night. Everything was great. I retrieved all my usual apps and previously purchased apps back down from the market, network was working fine. Turned on tab this morning and it is unable to connect to wifi. Keeps trying several times and then says the attempt has been disabled. It sees the Motorola Surfboard but can't connect. I thought I would try to re-flash since the .zip was still on my external SD. I attempted to boot into CWM but it won't come up. It just says loading image and never goes into CWM, that's it. So, I have no ability to connect by Wifi and am unable to download Acer Recovery Installer in order to re-install CWM. Apparently the CWM image is corrupt. The CWM ROM Manager Premium is still on my desktop but it can't do any sort of recovery because if I bring it up and choose "_install .zip from SDCard" it reboots into recovery mode and can't load the recovery image either. Does anyone have any ideas? Taboonay 2.1 is Android 3.2 it has the xda ad hoc wifi patch in it (which has never been quite right) in my opinion. So I found a copy of the 3.1 wpa_supplicant file and installed it into the /system/bin folder using root explorer to set the permission correctly after renaming the one installed by Taboonay to wpa_supplicant.old and re-enabled Wifi. Still it would not connect. The only difference I could see was that it no longer could see ad hoc wifi networks but still would not connect to my infrastructure wifi although it could see it. This particular wpa_supplicant file that I went back to came from Acer 3.1 stock ROM and worked perfectly under 3.1. I'm basically out of business at this point with no network and no way to flash a new ROM or restore a backup. Does anyone have any idea what to do next. Has anyone else had wifi issues with Taboonay 2.1? I did see an update 2.1b for Taboonay 2.1, but I can't get into CWM to apply it. I might as well be totally bricked. I can connect to the tablet and have full access to the 2 SD cards via Windows and a USB cable, but I can't download Acer's Installation Recovery from the market from a Windows browser. I'm sure its not the router because 3 Windows 7 SP2 Computers can connect to it and so can my wireless HP printer. Everything seems to be a Catch 22. Help! Anyone had trouble with Wifi on Taboonay? Does anyone have any ideas or how to get out of this situation? Any suggestion would be appreciated.
Hey gradyzero sorry to see the trouble buddy but the tabooney 2.1b update is made for wifi updates issues and SU perm, im currently running tabooney 2.1b and full with new market and i have no issues. As far as the recovery have you tried new THORS 1.5 cwm can you try using adb to push recovery.img to the tablet, or maybe using terminal emulator theres a new 1.5 cwm update you can try doing that. just extract recovery img to internal sd and go into thors website "google it" and follow every step except for #3
good luck buddy if not hit me up side PM ill see what i can do atleast to try to get recovery back
I don't think I had restored the terminal program back yet let me check. The apk is something I haven't tried. Thanks for the suggestion. I have thor's 1.5 update on my SD card but not quite sure what use it can be until I can get the ability to connect to boot up in recovery. I'll go to his web site and read the instructions there again, overlooking step 3. I have read them once before but didn't have this problem so I just grabbed the download and planned to update it after the Taboonay flash. Figured it would just have to be redone after the flash anyway. Thank for you idea. I should be able get an .apk onto the SD from Windows and should be able to install it. Again, thanks much buddy. I'll post back to this thread what the outcome is.
Restoration of boot image doesn't resolve the problem.
Okay Crashpsycho I download an Acer Install Recovery apk and CWM Launcher 1.0.0.0 apk. Both appeared to install correctly. Acer Install Recovery came up and I was able to choose to install CWM 1.3.4 image. However, when I reboot into recovery I still stop at "Booting recovery kernel image". So reinstalleing the CWM 1.3.4 image that the Acer Install Recovery show as an option didn't fix anything. Any ideas about why recovery might stop when loading the kernel image? When it says "the Kernel Image" is it talking about the base Linux kernel? I seem to recall reading somewhere that Taboonay replaced the Linux kernel with its own version. Is that true? I thought maybe the recovery image was corrupt but assuming the Acer Install Recovery really did reinstall the recovery CWM 1.3.4 image as it said, then something else is wrong. I did manage to get a terminal program installed so I'll try your second suggestion to force the CWM 1.5 image using adb. If Taboonay really did replace the stock Linux kernel, I have no idea how to recover from that. I'm not quit sure exactly where a recovery image goes and so I suspect that adb will ask for the destination. Maybe I'm wrong but do you know? Does adb know automatically where to install a recovery image? If the Linux kernel has to be replaced then I could get bricked if Tabtoonay won't boot up because a different Linux kernel is installed. What is your thinking about all of this? This is getting heavy. Thanks again for your help. Anyone else that has any fresh ideas is encouraged to jump in here and post to this thread. I'll post back here with the results once I try to force the CWM 1.5 image.
Installing other kernel solved issues for me, using thor kernel 3.5
installing 1.5 use terminal emu, extract the recovery.img from zip folder and place on root of sd go to thors website tegraowners and follow all steps except #3 and that will force 1.5 to tablet. have you tried installing stock recovery image using the acer recovery app
So Sector51 are you telling me you had the same issue. Where booting into recovery locked at loading kernel image? I'll try your suggestion. If it doesn't require you to be able to boot into recovery which I can't. Thanks for the tip.
Crashpsycho, I just completed the terminal method you suggested and followed all the instructions except #3 wihch was a mount, if I remember correctly. I extracted the image file from Thor's 1.5 put it on my external SD by copying it from Windows and then went through Thor's instructions step by step. Recovery boot still hangs at loading kernel image. Thor actually says to install itsmagic into /data/local directory both in his adb push and in his terminal emu methodology. There is no copy of itsmagic in his distribution and I can't find such a file on my tablet. BTW, I also tried the adb push from Windows but the recovery image is pushed to the SDCard so I assume he intents for me to then boot into recovery and to install it. So that's not going to work unless I have itsmagic. The Windows adb method also pushes itsmagic out to the /data/local folder but I can't complete that part and I think it is critical to both methods. Any idea where I get this file? Google search returns nothing except that one entry has been removed due to copyright issues. I think that it is the key to installing from the SDcard. I remember seeing that file on my rooted 3.1 but apparently Taboonay removed it. Can you enlighten me on itsmagic? What is it? Where do I get it? I have currently installed the Stock USA 1.31.06_COM_GEN1 recovery in Acer Recovery but reboot into recovery still hangs at loading kernel image.
This is another side issue but do you know if it would be possible to install the Taboonay 2.1b manually. Is it an update zip or a ROM flash? I'm beginning to think that if I could get back my Wifi back I would just forget the recovery reboot as a last resort. I'm going to investigate what is involved in the kernel update suggested by Sector51. But basically I'm not doing anything else until I can fully complete thor's 1.5 update. Man, I've spent 3 entire days trying to resolve this. I'm going bonkers. It certainly gives me a bad taste for Taboonay that probably isn't deserved because I don't see other post about this particular issue. So please educated me on itsmagic and we'll go from there. Thanks dude for all you help.
I found a copy of itsmagic here on xda. Downloaded it and completly went through the terminal emu process exactly as posted on Thoor's Website for 1.5. Everything seemed to work this time including the execution of itsmagic which spit out a nasty message to Acer something about Its Magic. Acer why did you say the bootloader is locked when it isn't? So this tells me that everything should now be good. I rebooted into recovery and this time it acted a bit different. It still said loading boot kernel but then in about 30 seconds rebooted back to Taboonay automatically. So I'm stumped. Does anyone have and new ideas? BTW, the 1.5 recovery image has a date of 29 Feb 2008. Is that right?
Finally suceeded with 1.5 Recovery, Thanks
This message is specifically addressed to Crashpsycho and Sector51. After four attempts I was finally successful at getting Thor's 1.5 recovery booted. I immediately backed up the current version of Taboonay 2.1 and then applied the 2.1b update. Everything in term of recovery is now good. One problem, the update did not fix the the WiFi problem as I am still unable to connect via WiFi. But that's a totally different issue, which I can deal with. Meantime thank to both of you for generously taking you time to help me resolve this recovery boot problem. I would still like to know what I did wrong during the original ROM flash to Taboonay 2.1 to destroy itsmagic. As well as what I did wrong in my first 4 attempts at repairing the recovery. However, I won't dwell on that as I need to proceed on with working on the WiFi issue. Thanks a million to both of you for all your help and suggestions. You are both what makes xda a truly wonderful and unique place for lovers of mobile devices. I am a programer and web developer and I hope I can contribute eventually to the growing Android mania. I personally think it will eventually dominate the table and phone market, if it already hasn't done so retail wise. I'll return to lurker stats for a while and learn more about the SDK while I try to resolve the WiFi issue. One side note, I recently flashed my HTC HD2 phone from Window mobile 6.5 to Widows mobile 7.5. That involved the flashing of 3 ROMs and then upgrading the OS. It runs beautifully and was much more complicated than what should have been a relatively simple task of upgrading to Taboonay 2.1. I'm sure I missed some small detail that caused the problem with the Icona Tab. You guys helped me greatly and I hope to be able to return the favor at some point. So I consider this issue closed and the moderator should feel free to consider it resolve. xda is power to the people.
Final Note: The adb push from Windows was the last attempt and was apparently the one that successfully fixed everything. As a certified Unix Engineer and somewhat of a Linux expert I opted to use the terminal emulator technique since I knew the commands and what they were doing, but typing in a long stream of commands is always more prone to user error. My advice to anyone else with this problem is to install the Windows Android SDK and use adb push to update as it appears the most recent version takes care of most all the permission issues and is almost fool proof. Again thanks to you guys. The Problem is resolved. Mister Moderator consider this thread closed and resolved.
great job man atleast you got the recovery to work. i cant say much for the wifi issue or what happen to recovery i would say if anything the issue must have came from the wifi ad hoc patch/change but im not fully technically skilled to say that it really was but great job hope you get it back up and going
I am enbrased to admit this but I feel it only fair since so many people attempted to help me. I've search around and apparenty no one has run into this here yet, but it needs to be posted for future reference. Most all of my boot recovery issues took place while the tablet was docked in the Acer A500 docking station. When I have trouble in recovery mode, with the image loading message just hanging up, 100% of the time removing the tablet from the docking station resoves the problem. Just thought I should pass this on. I know it is stupid that I didn't realize this before now. If you are docked, don't boot into recovery' not even with1.5 installed. I have no idea why this is true, but it is. If you have the Acer docking station DO NOT BOOT IN TO RECOVERY WHILE DOCKED!
Open up Rom Manager and click "Fix Permissions" let it do its thing then restart. That worked for me.
Hi everyone,
I'm using QBKing77's tutorial to manually upgrade my Nexus 7 to Kit Kat 4.4 (and up) but haven't been able to with ClockworkMod Recovery installed.
The video I'm using is on YouTube, titled: "Manually Update the Nexus 7 to Android 4.4 KitKat" and at the step at 3:38 I don't know what to do.
(sorry I'm unable to post links bc I'm a new user:crying
CWM doesn't have the 'Apply update from ADB' option that stock Recovery has (or at least I'm not sure what to do in its place).
If anyone knows how I can continue the upgrade process it would really help!
Thanks in advance :good:

Hi, hennimore...
From your post, I assume you have already CWM installed... if so, then upgrading is pretty straightforward. Assuming further, that you can boot your Nexus 7 into Android normally, you can flash an OTA .zip directly from the Nexus 7 itself... without recourse to ADB or a PC.
The first thing to do is to determine the build number of the currently installed version of Android you're running. This is found in SETTINGS>>ABOUT TABLET>>... and at the bottom, will be the build number.
Next, go here where you will find an archive of all currently known OTA .zips for the Nexus 7 (2012)... listed by build number.
Using Chrome (or whatever Android browser you're currently using) download to your Nexus 7, the correct OTA .zip(s) appropriate to your situation. Depending on how old your current version of Android is, you may have to download more than one.
For example... if you're currently running Jellybean 4.2.2, build JDQ39 on a WiFi only 'nakasi/grouper' Nexus 7, the 'update path' is as follows... and the OTA .zips you'll need are...
----------------------------------------------------
JWR66Y from JDQ39
Updates Jellybean 4.2.2 TO Jellybean 4.3
KOT49H from JWR66Y
Updates Jellybean 4.3 TO KitKat 4.4.2
----------------------------------------------------
Keeping in mind this is just an example (your situation maybe different), these should be flashed IN THE ORDER GIVEN ABOVE... slowly bringing your Nexus 7 up to date. From Jellybean 4.2.2 through Jellybean 4.3 and finally arriving at the latest build of Android, KOT49H - KitKat 4.4.2.
It's important you download the OTA's relevant to the type of Nexus 7 you have... so for a WiFi only model, you need 'nakasi/grouper' OTA's... if it's a WiFi/3G model, then you need 'nakasig/tilapia' OTA's.
Now to flash...
Once you've downloaded the OTA zip (or zips) to your Nexus 7... shut down the device completely. Reboot it into the bootloader, with the VOL DOWN+hold, POWER ON key press sequence. Once in the bootloader, and using the VOL BUTTONS, navigate to the RECOVERY MODE option, and press the POWER BUTTON to select. Your device should now boot into CWM.
Once there, select the INSTALL ZIP option, followed by the CHOOSE ZIP FROM /SDCARD option. Navigate (via the 0/ folder) to the /download folder on the internal storage of the Nexus 7... where you should find the OTA .zip(s) you previously downloaded via Chrome or other Android browser. Select NO, YES or GO BACK accordingly.
I'm not sure it matters, but if you have to flash more than one OTA .zip to bring your Nexus 7 up to date, then I recommend booting normally in between flashes... just to make sure everything is working OK.
Unless you're running a really old version of Android, say Jellybean 4.1.2, I can't see it taking more than a couple of reboots into CWM. And if you're currently on Jellybean 4.3, then it's just one OTA .zip flash.
A few caveats...
If you've modified system files in any way, these OTA's will fail, as they expect to find unmodified versions of stock Android system files. If they've been changed, say as a result of a Custom ROM or Custom Kernel flash... then they can't be 'patched', ie., updated... and the OTA will abort, with no changes made.
Root and having a Custom Recovery (CWM or TWRP) installed however, won't block an OTA... although you will loose both during the OTA update procedure.
If you're familiar with fastboot, then it's relatively straightforward to re-acquire them after the OTA update(s).
Hope this helps... and good luck.
Rgrds,
Ged.
Wow really appreciate and very useful for me Mr blake. Thanks a lot. One question, im in stock 4.4 krts160 with root and unlock bootloader with twrp cwm, i m going to flash the newest ota, will this step erase my root and relock my bootloader? Or i watch in youtube post by rootjunkies that twrp can handle ota. What would you suggest the better way. And thanks again for the information.

Hi, deny_kei...
You will loose root, and your Custom Recovery... whether that be TWRP or CWM.
I'm afraid it's unavoidable - it's always been that way with OTA's. You have to fastboot flash your Custom Recovery of choice again afterwards, and re-root... not difficult, but a bit of a nuisance nontheless.
Flashing an OTA, though, will NOT re-lock the bootloader.
The bootloader will remain unlocked until you purposefully choose to relock it with fastboot oem lock.
TWRP should be able to handle an OTA flash. I'm currently using CWM (with which I flashed the KitKat 4.4.2 OTA), but I've never had any problems myself applying OTA's with TWRP in the past.

Thanks so much for the helpful response! I should have also mentioned that I currently have AOKP running on my N7
(Version: aokp_grouper_jb_build-2 Build number: aokp_grouper-userdebug 4.1.1 JRO03L eng.roman.20120916.095343 test-keys)
I'm not sure how this affects the update process, but would definitely appreciate any other help you can offer.
Thanks again!

Hi, hennimore...
As you're running a Custom ROM, you can pretty much forget about OTA's... as they are only designed to upgrade official stock firmware from Google. If you were to attempt to flash any OTA on your Nexus 7 as it currently stands, it would abort almost immediately during the verification phase of the OTA update process. Because nothing in /system would match what the OTA expects to subsequently 'patch' (update) in the second half of the OTA update process.
Your only option, if you wish to have official stock KitKat installed on your Nexus 7, is to fastboot flash back to factory stock.
For this, you will need the full factory stock image for your Nexus 7, available here.
(Currently, build KOT49H KitKat 4.4.2 is not yet available as a full factory image... just KRT16S KitKat 4.4... but that's not a problem...'cos once you have KitKat 4.4 installed, you can then use an OTA to bring it completely up to date... as detailed in my previous post).
Instructions on how to restore factory stock are available here.
This process is more time consuming than it is technically difficult... because fastboot flashing back to factory stock essentially wipes the device... so before you can begin, you need to backup all of your apps and associated app data with Titanium (requires root), and then backup the entire contents of the Nexus 7's internal storage to your PC... for later restore AFTER you've fastboot flashed KitKat.
Fastboot flashing back to factory stock resets the device, as though it where new. You'll need to set up your WiFi password again... and re-enter your Google Account (gmail) details... and restore all your data from your PC... fastboot flash CWM or TWRP in order to re-root. Once rooted, you can then use Titanium to restore all your apps.
Longwinded and tediously time consuming, it certainly is... but it's the only way to get official KitKat on your Nexus 7 if you're currently running a Custom ROM.

Ah, I'm sad to hear that I must flash back, but I appreciate the information! Thanks again for all of you help, hopefully I can complete the process without any hiccups!
Thanks Mr Blake i will considered using ota, nevertheless my last ota i got stuck in the softbrick although my nexus is stock,unlock an unroot.

I've been following your steps and seem to have hit a wall when I need to install the adb drivers. I went to the link included in your instructions and followed their tutorial for a Windows 7 PC. After coming back to your instructions, I continued to the step with the Command Prompt.
I entered the command correctly as written, however I get no results under the List of devices attached.
I'm not sure if this is related to the problem, but when I am in Device Manager trying to Locate Android Phone in the right pane, all that shows for me is 'Nexus 7' - which I would assume should work.
However, after Right-clicking on 'Nexus 7' (Android Composite ADB Interface doesn't appear) and selecting Update Driver, I continue through the steps to where I must manually update the driver, and I received a message stating, "The best driver software for your device is already installed"
Under that it says, "Windows has determined the driver software for your device is up to date. MTP USB Device"
I'm not sure if you can make anything of this, but I figured I'd ask since you've been so helpful thus far :angel:
Hi guys,
I've been having problems to update to 4.4 in the Nexus 7 wifi version, the only thing I done is unlock the bootloader and root, once I tried the OTA upgrade it starts the process and then it shows up the Android little guy with an error, and doesn't shows the error of installation. I tried once the flashing the zip file using TWRP and it just failed. After the first failed the tablet just started to lag horribly. Any suggestions on how to fix this?

Hey again, so I was able to get beyond the point where I originally was at a standstill, and now have 4.4 installed on my N7 (Build KRT16S)
So now my question is, do I need to re-root my device, then upgrade to 4.4.2? Or am I currently rooted?
I don't see the option for USB debugging in my settings any longer...
Thanks!!!
I have tried updated ota on my nexus 7 root without unlocking bootloader on 4.3 update and it works fine but you will lost root . Is your nexus root ,unlock bootloader with twrp and stock rom? If thats the case try to update via ota. Ive just manage upgrade to 4.4.2 with ota 10 minutes ago with above situation. I only lost my root not the unlock bootloader. The twrp cwm can handled ota. Thats my advise .
Lets hear advise from others because i also noob in nexus 7
Thanks

Hey again, so I was able to get beyond the point where I originally was at a standstill, and now have 4.4 installed on my N7 (Build KRT16S)
So now my question is, do I need to re-root my device, then upgrade to 4.4.2? Or am I currently rooted?
I don't see the option for USB debugging in my settings any longer...

Hi, hennimore...
Sorry it's taken me a while to respond... been busy with family issues (I don't seem to have the time these days that I used to, to focus on Android stuff).
Anyway... taking your questions in order...

If you've just flashed a clean install of KRT16S, then you certainly won't be rooted. Nor will you have a Custom Recovery installed. You'll be runing 100% totally unmodified stock Android KitKat. The only difference between your Nexus 7 and the average Joe Bloggs' Nexus 7 (who just bought his yesterday)... is your bootloader will be unlocked.
With regard to applying the new update... KOT49H
Well, there are three routes you could go down...
1). Await for the OTA to appear normally in the notification bar, or go to SETTINGS>>ABOUT TABLET > > SYSTEM UPDATES... and tap on the 'check now' button. When the update appears (and sooner or later it will), it will be flashed automatically via stock recovery. This of course, is the standard method by which 99.9% of all Android users get their updates.
2). If you don't fancy waiting, fastboot flash a Custom Recovery, like TWRP or CWM, and then download the KOT49H OTA .zip directly to your Nexus 7. Boot into your Custom Recovery of choice (via the bootloader), and flash it manually.
3). If you haven't done much with your Nexus 7 (ie, installed lots of apps and copied lots of stuff over), since you flashed the full factory image of KRT16S, and you don't mind repeating the process... then the full factory image for KOT49H has now been uploaded by Google, and is available here. Download and flash it the way you did KRT16S. It goes without saying, that this will reset and wipe your device again.
*****
Addendum: It seems that Google have made a bit a mess (of some) of the KitKat 4.4.2 factory stock image download links... and when clicked upon, will give a 404 error message.
The corrected download links can be found here...
http://forum.xda-developers.com/showthread.php?t=2565531
*****
Whichever of these methods you use to upgrade to KOT49H from KRT16S... you'll need to fastboot flash a Custom Recovery afterwards if you wish to re-root.
With regard to USB debugging...

You won't... this is because Developer Options are hidden by default... presumably to prevent non-technically minded people from screwing things up.
To enable developer options (and by extension, USB debugging), go to SETTINGS>>ABOUT TABLET>>scroll down to BUILD NUMBER... on BUILD NUMBER, tap 7 times. You will see a 'toast' message that says something like "Congratulations, you are now a developer!". (If only it where that easy, eh).
Anyway, with Developer Options now enabled (which you should now find in SETTINGS), USB debugging can now be turned on.
Incidently, I've just seen a new option in Developer Options, called Process Stats - Geeky stats about running processes. I'm pretty sure this is new to KitKat, as I've never seen it before. Anyway, tapping on it does indeed yield some stats... which are interesting... Google however, consider them geeky. The implication being that anybody interested in such things is a geek. I just found it humorous, the use of the word geek by Google.
Humorous allusions aside about whether everybody on XDA is actually a geek...or not... I hope this helps.

Hi guys,
I've been having problems to update to 4.4 in the Nexus 7 wifi version, the only thing I done is unlock the bootloader and root, once I tried the OTA upgrade it starts the process and then it shows up the Android little guy with an error, and doesn't shows the error of installation. I tried once the flashing the zip file using TWRP and it just failed. After the first failed the tablet just started to lag horribly. Any suggestions on how to fix this?

It could be a TWRP problem...
Hi, Meshe...
You don't state which version of TWRP you're using, and what (if any) errors where displayed when the OTA aborted. If, as you say, you have performed no significant modifications to your Nexus 7, other than unlocking the bootloader and flashing TWRP (and rooted it)... then the 4.4.2 OTA should flash...
...however, there seems to be something odd about the behaviour of TWRP v2.6.3.1.
To elaborate... there is a known problem using TWRP 2.6.3.1 when flashing franco's latest kernel. See here for details on this.
This problem seems to relate to TWRP v2.6.3.1 itself, and not to franco's kernel .zip. The kernel flashes without problems using an earlier version of TWRP, namely v2.6.3.0 and also with the latest CWM recovery...
Nobody seems to know why TWRP v2.6.3.1 fails to flash franco r76, but fail it does. It appears that something is 'broken' in TWRP v2.6.3.1.
So I'm suspecting that your difficulties flashing the KitKat OTA might be similarly related to whatever is broken in TWRP v2.6.3.1... assuming of course, that this is the version you're currently running.
-------------------------------------------------
Here's what I would do... flash either TWRP v2.6.3.0 (the previous version) or CWM v6.0.4.3 (links below), and try flashing the KitKat OTA again. (I used CWM when applying the KitKat 4.4.2 OTA and it flashed without problems).
TWRP Recoveries...
http://techerrata.com/browse/twrp2/grouper
http://techerrata.com/browse/twrp2/tilapia
ClockWorkMod Recoveries...
http://www.clockworkmod.com/rommanager
(It's important you get the correct version of CWM recovery for your Nexus 7, as there are four CWM recoveries listed for the Nexus 7; two for the first generation model, and two for the second generation model.)
You'd normally fastboot flash a custom recovery, but if you're already rooted, you can flash a custom recovery directly from the Nexus 7 itself, without going anywhere near a PC... by using the rather excellent flashify app.
To summarize...
1). Install flashify on the Nexus 7.
2). Download to your Nexus 7 any custom recovery other than TWRP v2.6.3.1.
3). Ensure the KitKat 4.4.2 OTA update .zip is located somewhere on the Nexus 7.
-----
4). Use flashify to flash the custom recovery (It will request root privileges).
5). Boot (via the bootloader) into your custom recovery.
6). Using that custom recovery, flash the OTA... again.
Finally, if the above doesn't work, and the OTA aborts again, write down any error messages that are displayed. They can sometimes prove invaluable in diagnosing the problem, in order to decide what the next step is to take. Whenever I embark upon some project, for which taking screenshots isn't an option, I always keep my camera handy, such that I can take photographs of the screen... affording me a complete photographic record of the process, errors included, that I can review later. Very useful when things go wrong... as sometimes they do.
Hope this helps... and good luck.
Rgrds,
Ged.

Wow, erm, I mean yes... thanks... @zolaisugly... not quite how to respond to that.(blushing/embarrassed).
But thank you for your kind words, they're hugely appreciated.
I just try to help as best I can... 'cos I know what it feels like when you think you're 'bricked' or otherwise have problems with your device, as I had last year, with my (the then new) Nexus 7....and it's a uniquely horrible feeling.
You can read about my fumbling efforts here.
But it was posts here on XDA that got me back on track... and got my Nexus 7 working again.
So now, I try to give something back to XDA... my way of saying thanks I guess... and always I remember the stress I went through back in November of last year with my Nexus 7... so I can empathise with those who might not be so knowledgeable, or confident, or sure of their own capabilities, as some of the more experienced XDA veterans. And I try to help... when and where I can. Nobody can know everything... and everybody begins somewhere.
--------------------------------------
To all...
The primary rule I've learned in this past year, is if you think you've bricked your Nexus 7, or have some other seemingly intractable problem, is...
--- DON'T PANIC ---
Panic is an emotional response, and is the enemy of logical, rational thought.
It clouds good judgement... and may lead you to make BAD DECISIONS. Which will likely lead you to make a BAD SITUATION... WORSE.
Don't make any rash, uninformed decisions. It's understandable you want to get your Nexus 7 working again... but do some research first. Review your options. Read... and understand what you're doing... before you do it.
Carpenters and people who work with wood, have an old saying...
~ "Measure twice, cut once." ~
This axiom, I feel, is just as true and applicable to technology as it is to making chairs, tables and putting up a set of shelves.
Use XDA... If you've got a given problem, chances are good, somebody has had it before you, or has it now. A solution may already have been posted.
Use the XDA search engine... or go to Google search, and type "XDA ..." followed by some keywords that distill the essence of your problem.
I've never known Google search to NOT display something that might be pertinent to an Android problem... and usually it's almost always XDA that comes at the top of the Google search results.
--------------------------------------
Right... I'll shut 'up now.. I've waffled on far too long. And I don't want to earn the ire of the moderators for taking this thread wildly off topic.

OK well if you don't mind I'd like to pick your brain too . I am without a doubt no stranger to Android, rooting, custom roms, and so on, however this is my first experience with the nexus 7 (or with tablets in general for that matter), so there's just a couple of things I'd like to clarify if possible. I recently got a great deal on a 2012 32gb Nexus 7 WiFi, but I guess one reason why it was a great deal is because it came with 4.1.2 lol. So I have successfully unlocked the bootloader, rooted it, and flashed cwm recovery to it using wugs toolkit (what a great tool by the way!), and I originally assumed from this point on that I'd just be flashing custom roms like normal. After reading around for awhile I guess I must've confused myself, because now I'm not really sure what the "best" route to take would be anymore. First of all would I really need to flash every ota and build all the way up to 4.4.2 like described earlier? I found another thread that shows how to extract the boot, system, and bootloader images from the 4.4.2 ota off of Googles site, and then you could use wugs toolkit to flash them without losing data, would that work though considering I'm only on 4.1.2? Or should I just do all of the ota updates that pop up until I'm up to 4.4.2? I guess what I'm asking is what would be the best and or easiest way to get from 4.1.2 all the way to 4.4.2? I'm not concerned about losing data whatsoever just to clarify because I just got this so I haven't done hardly anything with it yet. I'm just under the impression that I can't even flash a 4.4 custom rom considering how old the version is on this, but I'm not sure if that's even correct or not.Anyway I'd really appreciate any insight or suggestions you might have because the last thing I want to do is rush into something and cause twice the work for no reason lol.

Hi, jeep447...
You're quite welcome to 'pick my brain', as you put it... but don't be too surprised if all you find in there is an oily rag, a half eaten sandwich and a dead D cell battery.
I'm by no means an Android expert; there are far more knowledgeable posters here on XDA... and they appear to be in possession of secret arcane Android knowledge, that is beyond my understanding.
However, I will try to help insofar as my knowledge allows. On to your question(s)...
First things first... if you're currently running Jellybean 4.1.2 on the device, then I think it would be a good idea to bring it up to date to KitKat 4.4.2 first... before you start flashing Custom ROMs.
Theoretically, it shouldn't make any difference if you where to flash a Custom ROM now, without bringing it up to date. But there might be an issue with the bootloader...
...which Custom ROMs WILL NOT update.
The bootloader can only (as far as I know) be updated by either...
-------------------------------------------------------
a) Allowing an Android update via the normal update route (or manually flashing the OTA yourself in recovery).
...or...
b) Fastboot flashing the full factory image that contains the new bootloader.
-- (however, see my Addendum toward the end of this post).
-------------------------------------------------------
I am not aware of any Custom ROMs that go anywhere near the bootloader partition. Which is probably a good thing actually, since a bad or incorrect bootloader flash has the potential for HARDBRICKING the Nexus 7.
My recollection is a little hazy... but I think with Jellybean 4.1.2, the bootloader was at version v4.13... since then, there have been two bootloader updates, v4.18, and the current version, which stands at v4.23.
You can check which bootloader you're currently on by booting into the bootloader as follows... shutdown the Nexus 7 completely. Press and hold the VOL DOWN button, whilst holding, press the POWER ON button. The Nexus 7 should now boot into the bootloader. On the lower left hand side of the screen, in a tiny font, you should find (amongst other things), the bootloader version number.
Now all of this detail about bootloaders might not matter... you could happily flash some new Custom ROM... and it might work without any problems with an old bootloader... but, on the hand, it might not.
So, I think, before you try tinkering around in the Custom ROM area... and If I where you, I would bring the Nexus 7 completely up to date, running Android 4.4.2 build KOTH49H (and the latest bootloader... v4.23).
The easiest and arguably the safest way of doing this, is to just allow the OTA updates normally, as and when they appear in the notification bar. Or, alternatively go to SETTINGS>>SYSTEM UPDATES > > and tap the CHECK NOW button. This is the method by which 99.9% of all Android users get their updates...
...and which is how I initially updated mine...in November of last year, when I first got my Nexus 7.
Running Jellybean 4.1, straight out of the box, once I connected it to mains power (updates won't occur if your battery is below a certain percentage), and acquired a WiFi signal... my Nexus 7 went through 3 or 4 reboots, upgrading from Jellybean 4.1 to Jellybean 4.1.1 to Jellybean 4.1.2 to Jellybean 4.2 (which introduced the world to Googles new and improved 11 month calender!). In December, Jellybean 4.2.1 was released, in time for Santa to arrive, which restored the missing month, December, in the date-picker.
Your succession of updates will be noticeably longer, as since then, we've had Jellybean 4.2.2, Jellybean 4.3, KitKat 4.4, and finally KitKat 4.4.2.
Along the way, with these updates, your bootloader will also be updated, silently and without you being notified of the fact. Most Nexus 7 owners are probably not even aware of the bootloader, much less if the latest OTA has updated theirs. So, the bootloader is not something you would need to normally flash directly yourself.
Of course there's nothing to stop you applying the OTA updates manually yourself, as I've written about here.
However you 'take' the updates, OTA's won't cause you to loose data... all your apps will still be there, as will your pics, videos and music files.
One last point concerning OTA updates... whether applied normally, or flashed manually... you will loose your Custom Recovery (in your case CWM)... and if you're rooted, you'll loose that as well... but it's easy enough to get both back after the update.
-------------------------------------------------------
Once your Nexus 7 is completely up to date, running KitKat 4.4.2, and before you do anything else, I recommend you make a Nandroid backup. I find it vaguely astonishing that so many people seem to miss this (IMHO) critical step.
Once you have a Nandroid backup under your belt... you can pretty much flash any Custom ROM or Kernel, safe in the knowledge that should anything go wrong with the flash, you can restore back to the point you where at before you flashed that ROM/Kernel or other 'mod'.
In fact, I don't think it would be a bad idea for you to create one now... whilst still running Jellybean 4.1.2... using your recently installed version of CWM.
Nandroid backups, whether created with CWM or TWRP, are a bit like 'restore points' in Windows... and I just think it's good practice and common sense, to have at least one good Nandroid backup stored on the device... before you start flashing stuff.
-------------------------------------------------------
Right... I think that covers most of your questions.
I'll try to keep an eye on this thread... in case you have any followup questions.
But I'm going to be pretty busy over the next week or so, what with Christmas on the horizon... so I may not respond immediately.
Good luck with your new Nexus 7... and, as ever... I hope this helps.
**********
Addendum
I've spoken at length about bootloaders and OTA updates. And I think this is your best and least risky way of bringing your Nexus 7 up to date.
Whist there is now available a full factory image for KitKat 4.4.2 build KOTH49 (see my sig for download links), I would avoid it at this time.
Apart from the fact it will completely wipe you're Nexus 7 (which is normal and to be expected) ... the STOCK FACTORY IMAGES, and the bootloaders that ship with them are currently in a bit of a mess. .. and may cause HARDBRICK.
See this thread for further details on this...
[WARNING][URGENT] N7 grouper (2012 WiFi) bootloader .img files from Google.
There are ways of working around this; (you need the bootloader from Build JWR66V)...
...but I suggest you stick with OTA's for now, to bring your device up to date...
Or at least until either Google sort out the 'dogs breakfast/pigs ear' they've made of the factory images... or until you've acquired sufficient knowledge and confidence in modifying a FACTORY STOCK image, such that it fastboot flashes a known GOOD BOOTLOADER.

It seems the n9 is eligible. Anyone has tried or thinking of trying? I might try
Flashing it right now. Just going to miss root, so u can drop my DPI and restore some apps.
Edit: sweet!! Though you can't fine tune the size, it now has default a way to change screen size/DPI. Now I'm only needing root to restore some apps and data.
Works pretty well for me so far, except for the fact that kernel support for libusb is gone, which stops my Headunit app from working over USB.
No root yet.
Recovery is replaced with stock recovery after a reboot.
There is more discussion in popular phone threads, like the one for Nexus 6p.

Same thing happened to me. The ota failed about 1/4 of the way through. Luckily my bootloader was unlocked. After reinstalling the system image and booting up it failed a second time when installing the ota. I think the ota has some definite issues.
Try the Nexus Root Toolkit to return to stock.

Well I don't think the kernel if it had libusb stopped supporting it.
Because this is pretty much what changed in it https://github.com/USBhost/FIRE-ICE/commit/b88667be3ca75cdfd67269e25fb43956d78004c9

if you want the N defconfig here you go https://github.com/USBhost/FIRE-ICE/commit/afdf42bd4af6aa042b9d9997de91d3e60c9ccc7e
I also went the OTA route and then got stuck in a Google logo boot loop. Boot loader is locked so I am trying a factory reset. Factory reset just finished as I'm typing this. It took about 40 minutes!!!! Once again seems to be stuck on the Google logo.
Edit--
Was able to get into fastboot and install factory image! Used the Nexus Toolkit to unlock the bootloader and so far things seem to be going smoothly.
I got the OTA and it installed fine 2 bugs I have found are if you're watching YouTube and put it in split screen with hangouts and tap the hangouts screen the video will go black until you tap on the YouTube side and the other bug is that the device decided to randomly put itself in airplane mode but over all I am liking it

Has somebody released N kernel source ?
I don't think there is any /dev/bus/ directory, never mind /dev/bus/usb/... but I'd feel more positive about that if I had root to verify.

Couldn't flash mine, always have "missing system.img" and "unable to allocate -xxxxx bytes"... Didn't have much time, I will try again later. Do I need to come from clean stock to flash it ?
I registered my Nexus 9 for the beta and got the OTA. But it failed with an ERROR (android on it's back with a !). It then rebooted and gets stuck at the Google logo for hours. My Nexus 9 was completely stock on 6.0.1. I downloaded the factory image, but I cannot unlock the device to flash it. All guides seem to say I need to enable Developer Options and enable USB Debugging, but since I can't boot into Android, I can't go that far. Am I screwed?

So being straight laced and not rooting actually bricked my tablet? What the hell....
I'm a bit surprised there's no way to flash a factory image when the bootloader is locked. If security is a concern why not sign the factory image? Make it something we can sideload like an OTA update.
I am in the same boat!!!

I am in the same situation. I figured that the software would be buggy but not actually brick my tablet. If anyone knows of a solution, I hope they post it here!! I would advise against installing this onto a Nexus 9 if anyone reading this is considering this firmware!!!

Couldn't flash mine, always have "missing system.img" and "unable to allocate -xxxxx bytes"... Didn't have much time, I will try again later. Do I need to come from clean stock to flash it ?

No, just wipe everything except internal. You have to extract the last image.sksmsksjssksm whatever zip. Then just fastboot flash each file individually.
Will I be able to recover if the Android N preview fails on my Nexus 9 by unlocking the bootloader and enabling USB debugging beforehand then install Android N preview?

In short, yes. You're basically leaving yourself a backdoor to flash a factory image should the Android N preview OTA takes a dump on you.
As my professor said to us in the laboratory: Do as I say, not as I do.
To be fair, I was hoping to do a no-wipe upgrade so I could experience Android N with all my stuff intact. I knew it was beta, but come on!
