I've just upgraded to 4.4 here on my Nexus 7 which has broken Kingsoft office which I require for my work.
Whilst I wait for a fix from Kingsoft, is there any way to roll back to 4.3 without voiding my warranty?
Thanks in advance.
Try quick office. It's free and works fine.
If you still want to roll back, you can do without voiding warranty
Download the one click factory restore from here

also your bootloader needs to unlocked for it to work and you will lose your data if you unlock the bootloader now.
There might be better options though. Wait for someone more knowledgeable to reply.

Thanks for that. The reason I need to use Kingsoft is because I need the data validation function on the spreadsheets with drop down boxes for what's allowed.

You can rollback to 4.3 system software however if you try to keep your user data your system will hang at boot. If you have a backup of your 4.3 user data then that is not a big deal. Alternatively if you wipe data factory reset from recovery that will get things working again.
You do need to unlock your bootloader and flash the factory images though.

You need to have the bootloader unlocked to flash anything unsigned. Currently the only thing Google sends out that is signed are the OTAs. There is no OTA from KRT16S/O back to JSS15*, so your only option is to use a factory restore. Since the factory restores shipped so far are not signed, you need to unlock bootloader.
You can unlock the bootloader here:
http://forum.xda-developers.com/showthread.php?t=2379618
During the process of unlocking bootloader, the system will wipe your userdata and sdcard for security reasons.
The post you reference assumes your bootloader is already unlocked.
So, you got two options left.
You need to unlock the bootloader under both methods. Remember it wipes user data completely.
After unlocking you can either flash the factory image for 4.3 or use the one click factory restore.
Personally I feel one click factory restore is easier

Yes, but I may be mistaken but unlocking the boot loader may constitute as voiding the warranty as well.
You would have to unlock it, which will wipe, downgrade to 4.3, then relock it to make it look stock.
Thanks guys I'm back on 4.3. How do I re-lock the boot loader?

You can get back to the 4.3 ROM w/o wiping user data (as a result of the unlock)
However the 4.3 ROM will not boot (will hang at X animation) with your user data once the 4.4 upgrade process has completed on your user data, so you will probably end up wiping user data anyway to get the boot to complete.

Boot to bootloader (Power+VolDown)

fastboot oem lock
Unlike unlocking, you will NOT have to wipe user data when locking.
Locking just sets a flag so it is very fast.
However, I would leave it unlocked if I were you and you are not selling it or getting warranty work done. If you ever need to unlock again you are going to be in the same boat of losing all of your data.

Let me ask a question. I've got my bootloader unlocked and I've downloaded the stock 4.3.2 from the Google Developer's site. If I don't want to do the one click restore can someone point me in the right direction for a good step by step? I've looked at a couple of different ones but none looked right or I'm not reading things correctly. To be honest I can't find the one I read from a couple of days ago. It addresses dealing with the tarball you get when you download the image from Google, but I'm really really bad about not using bookmarks. So I'm kinda stuck at this point now. Thanks in advanced.

Back up your sdcard to your computer, as unlocking will wipe that. As far as the Google Wallet question, I am not sure. I've never had an issue with it.

If you've been using your phone before your unlock the bootloader, then back up your "/mnt/sdcard" because it will be wiped when you unlock bootloader.
You must reset Google Wallet from within the apps settings. Open the app and go to settings>reset wallet. This MUST be done before you do a factory reset, unlock the bootloader, or flash a ROM otherwise you run the risk of breaking the NFC secure element for wallet.

Just unlock it now so you don't have to worry about backing up your sdcard later when you do unlock later.
You'll still get the OTA if your boot loader is unlocked.

No, it will destroy everything, even on the sdcard partition (backup before unlocking). Also, use the GN Toolkit, makes it very easy to perform.

there is a way, there is a thing called CasualRoot, which claims to but i havent tried myself. although apparently it only works pre 4.0.4.

Where did you get your phone? MOST Play Store phones from the batch last April/May don't wipe when unlocked.
Also, there's a hack/exploit that lets you unlock without wiping.
http://forum.xda-developers.com/showthread.php?t=1731993
1) If you have a Play Store GNex, you can unlock without wiping.
2) If you are running a build earlier than IMM76D (i.e., 4.0.4), you can root and then unlock without wiping.
3) If you have root, you can unlock without wiping.

I am yet another victim to dead pixels and pretty bad screen bleed so I will be returning my Nexus 7 to Walmart and picking up a new one from OfficeMax.
Should I relock my bootloader and unroot or just format data and leave it up to Walmart? I assume they are just going to send it back to Asus. What are the chances that there will be any kind of trouble since my warranty is technically void since I unlocked the bootloader and rooted it.
Thanks ahead of time.
If it were me I would unroot it and relock the bootloader just to be safe.
Im looking to unroot mines as well but dont know where to get the files to flash back to stock through fastboot, any help is appreciated...thnx

Yep, but a few minutes on Google or XDA search will yield you some images dumped from real-life Flo units, so you're good on that front for now.

Always do your own data formatting to be on the safe side. It's not like companies will maliciously steal your data, but mistakes happen and people can be careless. With Nexus devices, by the way, your warranty is basically protected so long as you go back to stock.

Is it a true system image? A true system image will overwrite or recreate all partitions. IDK if these will do that...

...a true system image will do no such thing. You do know what an image is, right? It's an exact copy of the state of storage media at the time of the image's creation. If you flash any image-- stock, modified, whatever-- it will overwrite whatever you tell it to overwrite.
You're mixing up the images with the flash-all script Google is nice and includes for you in their downloads.

I just did it because I'm sending both my original with all the screen issues (backlight bleeding, dead pixels) along with the "replacement" that was on the charger for about three hours and then decided to up and die all together back for a refund. The image flashed just fine so the device is now relocked and hopefully I can get my money back.

question....if you're rooted on stock ROM and just relock the bootloader....doesn't that wipe everything anyway? isn't that a security feature of unlocking and relocking the bootloader? or will it retain root.

It only wipes it when you unlock so locking it after changing anything will give you a device with a locked boot loader in the condition it was when you relocked it.

Yes you can flash the ftf directly, and here's what you'll get:
A stock ROM
unrooted
Lose some features related to DRM keys
No OTA
Stock recovery, which is none as far as i know
This is as close as you'll get to making your device feel locked.

Hmmm you're right, one can still relock the bootloader, but the TA partition along with the drm keys will still be missing, which will render the relocking kinda useless.
Better said, I don't understand the reason behind relocking if you're not getting the things you lost back.

I am guessing that OP wants to return his phone. If he is lucky, they will simply check the rooting status in the service menu and not if DRM keys exist.
Thank you everyone for the input.
If I do Relock the BL will it grant the device OTA updates or is that again TA/DRM reliant?
I just sold the phone on eBay for £200 so want to get it back to stock before I send it out tomorrow.
(Awaiting receipt of a pre ordered Z3c... there had been a significant price drop from £450 down to £350... So £150 for an upgrade seemed fair. )
You should get OTA updates if you relock bootloader. I've never tried but at least Sony PC Companian does not complain anymore about a modified device. I hope you informed the buyer that the device was actually unlocked though.

the APN settings get generated depending on the current service provider (currently inserted SIM card). Even then it might be the case that there are no pre-registered APN settings for that provider.
