You can flash the factory image but you'll lose all your data. Or you can use wugs toolkit and use flash back to stock option and it will do it for you but you still lose all data. Are you sure you want 4.3? 4.4 is smoother for me

So to be clear, even if the N10 is rooted, in order to go back from 4.4 to 4.3 one has to flash the factory image? Wiping the device and restoring a 4.3 Nandroid backup of a previous 4.3 ROM will not work?

Yes it will work but your progress since that nandroid is lost if you dont backup. You can also flash a 4.3 rom. Or mod the Factory image to not wipe your SD.

If 4.4 is more laggy for you than 4.3, you're doing something wrong.
Maybe just trying a factory reset of 4.4 might cure it.

I've tried factory reset with no luck. Still laggy.
Thank you all for your replies. It is really appreciated.
So what would be the easiest way for me to return my device to 4.3 using Google's factory images? Sorry for being a little annoying. I don't want to brick my device
My Nexus 10 is also more laggy on 4.4. Strange.
Is it laggy immediately after the factory reset or after you've set up your apps?

Yes it is laggy even after reset and reflashing the factory image with wugs toolkit. When the screen rotates, there is some stutter. I'm back on 4.3 and it's much better for me.
Thanks to abdel12345 for recommending wugs toolkit. It was an easy process
I installed via the factory image, and have no issues with 4.4. If anything, it's better.
Hi,
i go now also back to 4.3 because Simpsons is not playable on 4.4! It's soooo laggy. But only this Game.

Yep I've figured out that the resulting system when you do 4.3---OTA---4.4 is a slower system than if you do a stock flash install. I've also now unclicked the "backup and restore" to not carry over anything.
Prove it yourself, by all means... if you're going to flash down to 4.3, flash to 4.4 first, try it and then flash to 4.3 if its still laggy, but I betta 5cents you'll find it better. That one game - Simpsons - just install it and benchmark.
As I do not know what is the cause of this lag-from-upgrade, I now also don't click on the "backup and restore" to make mine as vanilla as possible. I've just now done this to my N4 also having found it better having done it on my N10 yesterday.
I been using WUGS NRT to do unlock (one time), flash+unroot, and root.
Am thinking of downgrading as well..

Anyone successfully bk to 4.3 w.o losing data?
Hi,
If you ever wondered if there was a way to restore stock without losing all your data, there's a way, which is not hard too... Just do the following:
Reboot in your custom recovery and then factory reset your device
Reboot system
Now download the Factory ROM and move it (the img files) to your adb/fastboot folder
Open a cmd there and do the following (remember to have the USB Debugging on)
Code:
adb reboot bootloader
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot reboot
Now wait for it to boot
Hope this helps you guys who want to downgrade to 4.3 and were afraid of losing your data (remember, the recovery still deletes your apps data, but you can backup it with an app like Titanium Backup).
I may write an script to do this soon... If you want you can wait for it (but it may be delayed up to this weekend).

That is useful to know but how is it any easier than simply copying to Wifi NAS or connecting external storage, copying it out and back in again? You'd be backing up anyways as a good techie. As you say it deletes everything bar data.
FYI if you did ever want to WRITE to NTFS volume then selinux mode changer app is what I use.

In my case this one is way easier, as I have almost 32GB used, and it takes a whole lot time to just backup, who says copying it back. I know it's good to always backup, however in some cases (like mine) it's a way easier method to do like I explained above.
This is just an alternative method I'd like to share, I actually used this many times already, due to soft bricks, then I can't simply plug a external hard drive on my recovery and it would take ages to backup my data via adb. This is the best unbrick method IMO, as you're installing fresh ROM without the need of formatting your data, and works as well with installing a new ROM .
Just my point of view hehe

I tried this!!! I do not suggest it!!! Nothing went.. wrong per say.. everything restored nicely and I went on my way, but it had more lag spikes, it had random freezes while screen was off that required a reboot, and biggest of all, it semi corrupted the sdcard partition so it couldn't be accessed, I ended up just wiping my device and starting fresh, works fine now to wipe I suggest locking boot loader and reunlocking to get it really well wiped. For the record my restore was with only data which a Dev deemed safer than a full restore but sadly as he suspected, there were problems. You can I think use titanium backup on non system apps pretty safely though

My answer was as specific as your 'question'. Assuming it is N7 to N7, with both in near identical states (I.e. ROM, apps, wipes etc) then it should work. However, restoring data is usually a hit-miss affair and YMMV.
'Old' and 'new device', as you stated, only make complete sense to you and the many mind readers and/or voyeurs and stalkers

Well we are in the N7 forum, and asking to restore data from a custom rom to a stock device would just be asking for trouble, lol.
yea golden rule, dont load a backup from one device to a replacement of that same device. apps are fine through titanium backup but dont be loading nandroid backups
I do this all the time across my devices .Restore my CUSTOM TI Backup but you need to selectively choose what to restore. This works ONLY With APPS AND APP DATA. NO SYSTEM APPS OR SYSTEM APP DATA. that is how the sd card becomes currupt. Also if you do a FULL BACKUP SAY OF YOUR PHONE. then selective restore some of it to A Say your tablet with apps and app data. THIS WILL ALSO NOT WORK IN YOUR FAVOR.
FROM the old device . do a backup of APPS ONLY no (some apps will work with apps and app data) THEN Restore that on your tablet or new device . Do not make a full backup of the old device then selectivity restore from it to the new device. This can also cause issues on the new device.
Hope this is not to complicated to understand im no writer.
The above is from my own personal experience with TI BACKUP... The above is how i have been doing it for years.. GOOD Luck

installed apps . (APPS THAT WAS not part of the rom)this will work just fine to backup and restore.. Even most will restore app data.
The problem comes when restore apps from one device to another where the app when it installs sets itself for the device type . Then restored to a different device type.. The issue with system apps is it could replace some system settings or files during the restore and currupt data or apps.
I just RMA my nexus device.
Used the command "adb backup -apk shared all"
That backed up my entire device and I didn't have to be rooted or have my boot loader unlocked.
Typed in "adb restore backup.ab" on my new device and was right where I left off.
You need the latest android SDK on you PC and you also need to run those commands as administrator.
I have an "adb backup" file from a stock, first-gen Nexus 7 16GB that was damaged. We replaced it with a second-gen Nexus 7 32GB, which has been rooted without touching the bootloader. We're having trouble getting the games to recognize their data when we restore them piecemeal, so I'm wondering if it would be safe to restore the adb backup from the old device to the new device? Are there enough differences to cause problems? If it fails, will I still be able to simply do a factory reset and get the new N7 back to factory specs? We've only had the new one a few days.
When I had 4.2.2 I rooted my nexus 7 without unlocking bootloader now after OTA updated to 4.3 I've lost root and I don't want to unlock bootloader to root and loose data. Is there any way to get rooted without unlocking bootloader or without loosing any data???

I am also looking for any updates about this root method.
any news?
I think it's pretty unlikely a 'motochopper' like exploit will be available any time soon.
Google, with Jellybean 4.3, have beefed up Androids security considerably, ostensibly to protect the device from exploits of the malicious kind. Whilst inconvenient for easy rooting, I think anything that enhances and improves security is most decidedly a very good thing indeed.
So, whilst I don't think a 'root-without-unlocking-the-bootloader' exploit is totally impossible under 4.3, I do consider it improbable.
And in any case, updating and rooting 4.3 from a locked bootloader condition (without loss of data) isn't technically difficult... it's just time consuming.
It took me about 2 hours or so, to go from a CyanogenMod 4.2.2 ROM/franco kernel combo to Jellybean 4.3 Factory Stock and rooted... with no loss of data. Using these steps...
1) Backed up all my apps (and app user data) with Titanium.
2) Copied the entire contents of my Nexus 7 (including my Titanium backups) to my PC, using ADB pull.
3) Unlocked the bootloader. (I was bootloader locked, rooted via motochopper).
4) Fastboot flashed Jellybean 4.3 Factory Stock.
5) Fastboot flashed TWRP.
6) Flashed Chainfires SU root updater.
7) Copied everything back to my Nexus 7 from my PC.
8) Restored my apps (and app user data) using Titanium.
(If you're already on Jellybean 4.3, you can skip step 4).
Besides, what else are going to spend a few hours doing on a rainy Saturday afternoon with nothing worth watching on TV? And such an exercise will confer several benefits...
1) It will hone your data husbandry skills (backing up data is always a good thing).
2) It will fine tune your knowledge and experience of fastboot and ADB.
3) It will root the device... and finally...
4) You will gain the satisfaction of your accomplishment.
OK... maybe I am trying to oversell it a little.
But my point is... you can either wait for some future putative exploit (that may never come) from some genius developer (who may not exist)... or you can bite the bullet, and do it the old fashioned way... today.
Anyway... just my thoughts.
Rgrds,
Ged.
Honestly if you are going to unlock/root it, use an app like helium(play store, free) to back up app data, and then move it to a computer, and then finally move it back, install helium again and restore. I did it.

Thanks for your advice I know the benefits of the standar rooting but you forget the benefits of being stock!!! The backup way of rooting an no loosing data is the only way but I have a plenty of time to wait for someone to make possible to make root without unlocking the bootloader. I don't use so much my nexus and the apps that wants root so I can wait, everything I use now after the update to 4.3 is free.
Thanks in advance for your answer!!!

Hello xda-dev,
I'm having trouble finding somebody else with a similar situation as mine:
So I picked up my new I337 from Costco this week. While using it throughout the week, I was very unfortunate as to allow the MF3 update from ATT to successfully update on my device. (This is the part where I cry because I can't install GE or custom bootloaders)
While doing some more research, I finally used this method to get root access after which I got Titanium Backup to remove the stock ATT bloatware.
I then proceeded to carefully un-install about a dozen or so applications most of which were ATT garbage.
Now maybe I uninstalled something crucial, or maybe certain applications need the ATT bloatware to run correctly, but my problem now is that Music and S-Voice both crash moments after starting them, so I would like to re-install my OTA MF3 update.
I understand that I have no shot downgrading or installing custom boot loaders at the moment, but I know that the MF3 rom seems to be available here.
Is there any risk in me getting Odin and attempting to install the rom using down+home+power way? (Sorry don't know the name for this procedure yet.)
I have come to peace with being stuck on MF3, but at the same time I would like to regain full functionality of my S-Voice and Music.
How would I go about safely re-installing my OS?
Using titanium backup, set both programs to be user apps, reboot, and switch back to system apps. Worked for me with Svoice, Smusic, and a few other programs. No more "Unfortunately xxxx has stopped" messages.

Just so its clear, you can NOT flash the rom in your link. Luckily, you won't be able to since you don't have a custom recovery. Trying to put a recovery on and flashing that rom could cause irreparable damage to your phone. You're mf3 and are severely limited to what you can do.
If you continue to mess with tibu, freeze the apps, don't delete them. That way if you mess something up you can get them back
You extract the contents of that ROM, and a manually add in the missing apps until your problem dissapears (will prob have to change permissions on each added app to "rw-r-r" and reboot for apps replaced apps to take effect)
That should work...and next time use titanium back up to actually back up, than freeze apps reboot see if there's any problems...if none than uninstall

Just to add to their arguments, absolute no flashing with odin on the MF3. Period. You will definitely mess something up. I'm thinking you altered the system recovery by getting rid of some stuff. You are going to have to wait until the devs come out with something.

Hi, pleasant...
Both of the above responses are true... a factory reset will not touch the system partition, thus you will still have root... and, in the hugely unlikely event should you loose root, it's trivially easy to re-acquire again...
* Fastboot flash a Custom Recovery; TWRP or CWM.
* Using that Recovery, flash Chainfire's SuperSU Root Updater .zip
-----------------------------------
"...i dunno what stuff is eating my tablet space..."
But before you do that.... don't you want to know what it is, exactly, that is 'eating your tablet space'? After all, it could happen again, at some point in the future.... unless you get to the root of the problem.
Checkout this app on PlayStore, DiskUsage for a very nice graphical overview of how your space is being 'carved up'.

Background
- I'm using PAC 4.2.2 ever since I bought my Nexus 4 and was quite happy with the ROM until yesterday
- I started losing out the GSM signal for the past 2 weeks, it would intermittently go off and then come back by itself after a few seconds, at times few minutes (never thought it could be a ROM issue, is it?)
- Google started pushing its update and I had to manually stop data for Google Services from Settings -> Data Usage
Problem
Yesterday while updating Angry Birds from the Play Store the Play store crashed. I tried to open it but it would continue to crash as soon as it would try to load it.
I rebooted the device however since then its stuck on the google logo and doesn't proceed.
I have TWRP recovery installed and when it boots in to (Fastboot is it called?) it shows Secure Boot - enabled and Lock State - unlocked.
Few foolish things that I tried yesterday (in desperation) that might have already screwed up my phone beyond recovery....
1. Wiped Cache and Dalvik Cache and tried to reboot but it didn't work
2. Flashed the new PAC 4.2.3 version that I had downloaded way back but still no success
3. Tried to take a backup from TWRP recovery however while restoring it fails and shows the message 'Restore Failed'
I really wish to recover the media that is in the phone and contacts if possible.
I have Google Nexus 4 Toolkit (not sure of the version but its like 8-10 months old) installed in my laptop and if I connect the phone and start the toolkit it recognizes the phone against adb (shows a serial number) but when I try to back it up it stops at 'Waiting for adb mode...'
I'm a total noob when it comes to recovery etc. so would really appreciate any help that leads to data recovery in my phone somehow, thanks!
Internal memory is accessible through ADB over recovery so you could easily get your data if it is still there. About the contacts - if they are Google contacts and saved to your gmail - happy days, nothing to worry about. But if they are phone contacts I don't think you'll be able to restore them.
Do you know what is the worst thing about smart phones? That the owner should be smarter than the device in order to operate it.

What would be the steps that I'd have to follow for this? I have TWRP recovery installed.
EDIT: I even tried a complete wipe but it doesn't work. Also tried using CWM as recovery, that didn't work either. Installed the Unified_Android_ToolKit (latest version), updated all USB/adb drivers but whenever I try to backup anything through the toolkit all I get is that it is waiting for the adb mode or its waiting for the USB debugging to be enabled (which I can't since I can't get the phone to boot up).
Any ideas?
Don't try to restore any data after full wipe. It won't work. Flash factory images to get your device into operable state again but before that go to Device Manager and make sure that the phone is recognized by the computer and the drivers for it are properly installed. Good luck. Can you still access twrp recovery?

After having given up all hope to retrieve any data or contacts I wiped the entire phone, format data I mean. However, with that I've ended up with no OS on the phone, I can access TWRP though. Not sure how badly I've ended up screwing the phone. :silly:
Not badly at all... Reboot your phone into Boot loader mode. Download the Google factory images of your choice and run the flash-all.bat file. Enjoy your fully restored phone in a couple of minutes.

How exactly do I run the flash-all.bat file? I tried flashing the factory image using the Unified Toolkit however there comes an error message stating that there is some issue in the program and it has to close. This happens somewhere midway when it starts flashing system.img and recovery.img
EDIT: I can't get in to recovery mode any more and neither can I flash any recovery
EDIT2: Don't ask me what I did, somehow managed to get the phone running in the 4.2.2 version of stock factory image. 4.4 wasn't working for some reason. Setting it up for use now.
Question: Can I simply download 4.4 factory image and install it on my Nexus 4 which came with 4.2.2. when I bought it?
Simply: Yes

Even when I wasn't able to follow any of the instructions you provided (my bad though) I would like to thank you for just posting on the thread man! :good:
BTW a good news that I'd want to share is that my contacts were backed up I lost on the media but its fine I think, probably a good lesson for future.
I'm updating to 4.3 from system update as of now, will use it as it is for time being and move on to 4.4 sometime later maybe. Not sure whether 4.4 will be available for update OTA once I move to 4.3 but I'm happy with whatever's left of the phone for now...thanks again!
