Hey folks,
I just got my Nexus 7 and updated it to 4.4.
After that I unlocked and rooted it using a tool made by wug(something). After successfully doing that I realized that there was 4.4.2 update, as it showed me a notification in the top drawer.
So I went ahead and reinstalled stock firmware + unroot (using said tool). I used KRT16S factory image to do that.
After that I did another fac. reset as suggested but now I can't seem to be able to update to 4.4.2 anymore. When I search for updates on the tablet it says I am already on the newest version...
Is my N7 bricked? How can I update? Please help...
Your tab is not bricked at all.

If you can still use your nexus and browse settings, your tablet is working properly. I have the same problem, my OTA checker tells me it is up to date but it isn't. You can ADB sideload the firmware update instead using your PC.
You can follow the method from this site:

I bought a phone on eBay to use on the Ting (Sprint) network. It is a used Samsung Galaxy S3 running Android 4.0.4 which I thought was strange as I know the S3 has been updated past this. So I started looking around and I found a program called SuperUser which has root options, then I found a file called TeamEpic-Root-from-Recovery-v5(1).zip in the root of the phone. There is a firmware update available but when I try to apply it a screen comes up which says installation aborted (I can get more info if needed on this).
I have been using Android phones for years and never been interested in rooting. I'm worried that I will not be able to activate this phone on July 8 when I can get out of my Verizon contract. And I'm concerned that I won't be able to update it past 4.0.4.
Could anyone advise how I can get this back to stock? Thanks in advance.

Can't apply OTA update if it has custom recovery such as TWRP or CWM. Has to have stock Samsung recovery. You can try this post-http://forum.xda-developers.com/showthread.php?t=1904099. Follow instructions very carefully. This should do the trick to get you back unrooted, with stock recovery, and updated firmware to MD4.

Look in the Android Development section and there is a ROM Restore so you can restore to unrooted stock
Thank You!!

Starting with your link and checking some basic firmware flashing instructions I was able to get it back to stock. The counter is reset and it says it is genuine samsung After doing this it then updated to JB. Happy now, thanks so much for the help.
I am currently using N7 FHD (2013) with JWR66N 4.3 jellybean. I have just UNLOCKED BOOTLOADER but NOT ROOT or install any RECOVERY.
ALL ARE STOCK ROM, STOCK RECOVERY JUST BOOTLOADER UNLOCKED.
After that I got a CLEAN (Wiped) nexus. and I got a 5X MB OTA from google and I reboot. but after that, the android robot lied down and showing a RED ! icon and "ERROR".
I rebooted my device, it starts up normally.
IS THAT I CANNOT USE OTA AFTER UNLOCKED THE BOOTLOADER????
WHAT IS THE CURRENT NEWEST BUILD NUMBER FOR NEXIS 7 2013 FHD 32GB??
how can I get that OTA again???
If you really didn't modify or remove any of the stock files, then you are probably suffering from the JWR66N won't update to JSS15J problem mystery we are trying to figure out here:
http://forum.xda-developers.com/showthread.php?t=2380258
We know that it is caused by a file on your tablet being different than what is expected and we know how to workaround the problem. We just don't know why it is happening in the first place.
If you want to help solve the mystery, post on that thread.
If you just want to get JSS15J it may be quicker to just use the JSS15J factory restore here:
http://developers.google.com/android/nexus/images#razor
(factory restore will wipe your data so back up first)
Thanks for your info.
I think i can re unlock my bootloader again.
I am afraid that BL unlocked cant enjoy OTA and now i understand thats the OTA file error from google and not mine.
But google is still so stupid that they cant reconize my OLD (non full HD 2012) nexus and new 2013 nexus. They both have same names in google play store. Thats weird

I think you understood properly, but I didn't answer your question directly, so to be clear, the OTA, under normal circumstances, would work fine on a tablet with unlocked bootloader (unless files were modified or removed)
What we are trying to figure out is why for some tablets there is a rare occurrence of a file not matching the shipped set of files that everyone else has. It is usually just one file, /system/app/PrebuiltGmsCore.apk, but there was one example of someone having the same issue with /system/lib/libchromeview.so
My NEXUS 7 (2013) is running on Android 4.3 with the build version JWR66N
The Problem is that i get an OTA update notification for Android 4,3 System Update which is of appx (56 MB).
When i try to install it the Tab reboots and the update fails and it restarts again with the same build version ie. JWR66N.
Again after 2-3 days i get the same notification for that 4.3 System update and again it fails. PLEASE HELP !!!
How will i update to android 4.4 ???
I dont want to sideload or root.... Please suggest a normal fix !!!

You likely have the problem that some system files got corrupted because of bad EMMC.
When the update fails and you have the fallen android, press/hold Power, then press/release VolUp, then release Power.
This will show you the error and can confirm or refute this diagnosis.
If you want to get past it in the more efficient manner, you'll probably need to unlock the bootloader, then flash one of the factory images.
I will see that when the OTA notification comes again..... But how can I solve the problem.... is anyone else facing it ?
Will I get an Android 4.4 update ?

As I mentioned you'll probably need to flash a factory image to get around it, or you'll have to identify each file that is corrupted and replace it.
If you don't resolve the problem you won't get the 4.4 update automatically, but you can manually install the 4.4 factory image.

I and the op posted extensively in that thread. All the solutions there require unlocking your bootloader. If you are going to do that you might as well just flash the factory image.
Ya see that's what the problem is I don't know what's unlocking boot loader and flashing stock ram etc

Person on the other thread mentioned they got a JWR66N->KRT16S OTA update.
Previously we had only seen JSS15R->KRT16S updates, which would mean you would need to get from JWR66N->JSS15R first. The JWR66N->JSS15R update would fail for you, but there is a chance a JWR66N->KRT16S update would work because more files are shipped whole and not as patches.
Regarding the youtube video, it should get your where you need to be. I would skip the relocking of your device though to keep future flexibility in case something like this happens again.
If you want to be on KRT16S(4.4), then just flash the KRT16S factory image. If you want to be on the latest 4.3 then flash JSS15R.
Keep in mind unlocking the bootloader will erase your use data (including your virtual sdcard) so backup anything important and move it off the tablet to your PC or the cloud.

Hi, i have some kind of problem with my nexus 7 2013.. I already have lollipop 5.1.1 official on my tablet and have root and unlocked bootloader (root with king root, yes it works and is rooted.. And bootloader unlocked with boot unlocker.. I know you might think that this are not the best way of rooting or unloking the bootloader but it worked for me and im happy) and since yesterday the tablet keeps telling me to update via OTA the 5.1.1 update witch i already have..i press update to install it as normal, it reboot as normal too and when it shows me the parte where it suppose to be installing the update (you know, with the android with the chest open part) the only thing that says is "error" it doesn't install anything..i did this like 3 times now and every one of them says error.. The annoying part is that it keeps showing me the notification to update it..so any solutions? Thanks!
Sorry for bad english blah blah...
You can't take ota updates if you modify system files, you did that with root. Don't know why it's showing you 5.1.1 when you already have it.
Just flash the factory image with fastboot (probably no need to wipe, just flash boot.img and system.img and format cache).
That should fix the problem. It will also remove root. I'd recommend not using that king root **** but whatever. Probably better to just flash the su zip in twrp or use CF-Auto-Root.
When the next update comes remember you won't be able to take the ota. But that doesn't matter since google posts factory images and all you need to do is flash it with fastboot, then root again.

^Oh yeah, lol.
Still the rest of my post will get it installed for op.
I watched a few videos on YouTube on how to upgrade the Android O/S but none of them mentioned that it needs to unlock the bootloader 1st.
So before I found out that I need to unlock it I tried installing ROM before I knew that.
The phone came with Android Kitkat 4.4.2 and there is an official Lollipop for it that I want to install.
The device is rooted with Kingroot.
I tried the installations two times and the phone still works but I can no longer boot into recovery mode or fastboot mode. It just hangs and then I need to remove the battery to get it to work again.
I just want to restore it back to what it was before and then I will work on unlocking the bootloader.
I prefer to use tools that are free of cost.
Issue has been resolved.
I flashed the device with a pac file using SPD upgrade tool and now all is back to default.

Hi. I recently messed up my phone (Y560-U02)! Please help me.
Can you please tell me where I can find the "pac file" and "SPD upgrade tool"?

You meant un-official, right?
Sorry for the delay. I check the linked email once per month.
Do you still need help on this?
I thought that it was official Lollipop. But it does not exist for this phone.
Yes I can help you get it to what ever you need but it is not easy if you want to do more than just resorted it back to default.
I will tell you more if you still need it.
