Don't know about the bootloader but the instructions say that if it's not unlocked, it will unlock it (and erase). I think you might be right about the cable. I have no idea where the stock cable is but I will go through all that I have.

Thanks.
[Nexus 7 General] ravage485:
No problem. The cable thing gave me a lot of trouble for a long time, and it isn't present in all lots, but some people have found this to be the case. Also it looks like Wug has updated his automated toolkit to work with 4.3 already, you may want to give it a try http://xdaforums.com/showthread.php?t=1766475

Are you going stock and unrooted? Otherwise why would you want stock recovery? You can't do anything with it.

Can someone guide me to the latest bootloader zip file for 4.3 for Nexus 7.

Thanks in advance.

Nexus 4

Rom - Paranoid Android 3.91

Kernel - matr1x v10.5
[Nexus 7 General] niav:
Thanks for the reply. I am stock and rooted. I have been since 4.1. I was led to believe that having a custom recovery would prevent future OTA updates.

To be honest all previous updates were just a matter of installing the OTA and using Voodoo RootKeeper to regain root. This update to 4.3 has been a pain involving reflashing stock 4.2.2, installing 4.3 and rooting.

I'm actually quite lazy and would prefer not to have to do all this again.
[Nexus 7 General] ravage485:
No, it doesn't connect as a mountable drive. But keep in mind if the drivers are old or wrong it still may show and sound (the little windows ding) like it is correctly connected but you won't be able to upload to fastboot

---------- Post added at 03:59 PM ---------- Previous post was at 03:51 PM ----------

If you didn't have any modifications to the stock firmware besides root, you should have just been able to flash the OTA without a problem (that's what I did). Having a custom recovery really has no bearing on how the updates are applied. That being said if you are sure you want to return to stock, I'd suggest using Wug's tool http://xdaforums.com/showthread.php?t=1766475 The tool will warn you before it formats anything; I cant remember if you lose data returning to stock recovery or not. Honestly though any time you mess with the recovery you risk something going wrong and having to start over clean anyway, so I'd just back it up to be safe :)
[Nexus 7 General] niav:
AFAIK I didn't have any modifications to the stock firmware. The OTA downloaded but when I tried to install it I got an error and the device eventually rebooted back into 4.2.2. I'll try Wug's tool. Thanks for your help.
[Nexus 7 General] :
If you have no plans to modify anything whatsoever, system wise, then sure, go stock recovery and rom. But to be sure you don't waste your time, I'd unroot. If you modify the system you'll just bugger your next OTA. ;)

Heh heh heh
[Nexus 7 General] jonmorris:
It isn't set by default and that article makes it sound like the feature is a bad thing. In most cases, it really improves location services, even when you're not wanting to use WiFi.
[Nexus 7 General] Bob Smith42:
Thanks. Well this feature was enabled by default on my new Nexus 7 (2013). I did not know about it. I am not rooted, not unlocked, pure stock 4.3 on new Nexus 7 (2013).

Two nights ago I had to give a presentation on the new Nexus 7 (2013) in a company with lots of wi-fi access points but none of them open.

When I turned on my tablet (awake from sleep and entered pin) there were over 100 to 150 launcher crashes. No sooner clear one than the next occurred. I clicked through about 50 before abandoning attempts, and rebooting (era WIndows XP ? eh?). After login again I clicked through another 50 to 100 but they kept coming. I rebooted once more by again holding down the power button. On the third attempt there were even more yet after clicking through about 50 more they stopped coming.

I have never seen this happen before but I *hugely* suspect there was a problem related to the wi-fi stack.

About half the attendees left the presentation because this was a total PITA. After I finally my tablet working I was able to continue my demonstration. However, I never attempted to log onto their networks - not once.

----------

UPDATE: Interesting. There are a couple settings differences between Android 4.3 on my new Nexus 7 (2013) wi-fi model, and my 1st Gen Nexus 7 (2012) wi-fi model, also running Android 4.3 OTA.

On Nexus 7 (2012) under advanced wi-fi the "Scanning always available" is disabled by default, yet under same settings on new Nexus 7 (2013) it is enabled by default. At least that is what I see after accepting defaults from OTA upgrade on 2012 model, and after default setup and one factory reset on 2013 model.

On new Nexus 7 (2013) under advanced Wi-Fi there is "Wi-Fi frequency band" selection for Auto, 5GHz only, 2.4GHz only.

On new Nexus 7 (2013) under settings Display there are two new options. Pulse light notification, and Wireless display (Miracast). I thought Miracast was a feature of Android 4.3, but no, it is specific to both a device type and version of Android. E.g. The new Nexus 7 (2013) has Wireless display but not the original Nexus 7 (2012) with OTA update to Android 4.3.

On new Nexus 7 (2013) under Wireless & networks there is a new setting for Tethering & portable hotspot. But, I'm not sure how its used. Click option reveals four more features: USB Tethering, Portable Wi-Fi hotspot, Set up Wi-Fi hotspot, Bluetooth tethering.

I did not notice any other differences in settings between different Nexus 7 wi-fi devices on Android 4.3.
[Nexus 7 General] Nate2:
Yes, if battery was not an issue.

How did we manage all these years without background WiFi scanning and background location services?

Google must want to track me more badly than I want to track myself. Lol.
[Nexus 7 General] marathone:
Never ever give a presentation on a new device without thoroughly testing it first in the environment you're going to use it in! You did an amateurish thing.
[Nexus 7 General] Nate2:
Strange that no Google WiFi Engineer ever used his 2013 Nexus 7 in a place with very many WiFi connections... Maybe Google should consider that as a test scenario and come up with a fix for the "multiple launcher crash" syndrome described above.
[Nexus 7 General] Bob Smith42:
True. Meetup is for amateurs, doing beta testing for Google is not our job nor intent at meetups.

It was a meetup at a location with security - we don't get access to the site before the meeting. Unless you mean predicting unexplained crashes on a new device that did not crash like that for 6 days prior during all tests?

Part of the presentation was about the new Nexus 7 (2013) features and how it was rushed to market without adequate QA. We mentioned things like release with development keys, Best Buy devices failing to update, allowing app backup to reinstall all your old apps on 4.3 is a mistake since many are not compatible, etc. We had excellent Q & A at the meetup.

For the 10 attendees that hung in after we got the new Nexus 7 (2013) working, the rest of the presentation went fine on Miracast and Chromecast (limited). The purpose of this portion of our meetup is to show untested technologies. We've been presenting Android stick computers for months, Android-x86 on 2007 era eee PCs, etc. Stuff always crashes, just not often the new Google stuff. LOL

You gotta be able to push outside the box and do more for it to crash or break..

EKKKK i FEEL SICK now i talked good about apple products..

my thoughts on 4.3 is battery life in standby has been trippled on my device.In use battery life i cant see much of a change..I flashed back totally stock rom but still have custom recovery and root. so i could get a fair and untainted assessment .

Good Luck

If you have some numbers pertaining to standby battery usage under 4.3, I'm all eyes :)

[Nexus 7 General] erica_renee:
maybe i said that wrong..

I keep wifi on when sleep.. and it will sync using a app called DS CLOUD. This syncs with my home SYNOLOGY Nas disk station . Some important work files . I can get 4 days with it in my purse before 4.3 and it would be dead or close.. I Put it on the charger this morning and its been 3 days and had 80 percent battery.. So I Really have no proof just what i think from my observation. I will watch the battery take a screen shot when fully charged then again in a few days or so . I do not always go 3-5 days without charging but have gone 7 and find it dead..

Sorry i there was misunderstanding.. I have never went 13 days without sync or wifi But i do believe it can do so .

The data i sync is a bit less then 4 gb. It does changed a few times a day but only by very small amounts and it only syncs changed bytes not the whole files.

So i guess accuracy would be hard . I Just know its better ..
[Nexus 7 General] Bob Smith42:
Bluetooth seems working fine. The Sony SBH-20 NFC pairing seems to happen when swiping the device on the back of the Nexus 7 directly in the center. Quality of audio is great.

I have not tested pairing all my bluetooth devices, nor response time on keyboard.

-------

UPDATED: I tested playing music while typing fast with both headset and keyboard connected on bluetooth. Worked great.

Also got OTG working with small microsd reader plugged into micro usb port and running Nexus Media Importer (NMI). The microsd card was formatted FAT and NMI could both read/write (paid version advanced feature) via OTG.

[Nexus 7 General] jonmorris:
I have no idea sometimes how I used to cope before.. I think back and wonder how I even survived before getting my first mobile phone in 1990/91. I remember having used a pager for a while, and even payphones. Urgh!

I use loads of services on Google/Android that kill the battery. It's why my smartphone (or tablet) is now so useful as it can relay information and notifications instantly. The price is always battery life - which is why I'd rather some manufacturers concentrate on putting in bigger batteries than trying to make them wafer thin all the time.

If I turned off background syncing, Google Now, GPS, 3G/4G data and so on, my device would probably last three or four times as long.. but at the same time, it wouldn't be helping me as it does now.

This new feature will help me use things like Google Maps when I'm out and about, such as coming out from the Underground and not wanting to wait for a GPS fix. To me, it's worth the extra impact on the battery and a great feature to have added. Previously, most people probably left Wi-Fi on at all times anyway.
[Nexus 7 General] GldRush98:
Anyone noticed laggy volume changes?
[Nexus 7 General] Nate2:
If power weren't an issue, I'd probably leave everything on. e.g. my desktop pc is never off, sleep or hibernated.

I've been in situations where my DroidX phone wouldn't last 24 hours on a charge. And I came from a Windows Mobile 6 phone that could easily do 4 or 5 days between charges. Since my DroidX is not rooted, I can't disable many things like I can on my Nexus 7 (like auto OTA updates). But I did find some apps like JuiceDefender and Auto Airplane Mode that can stretch battery life on the phone.

I turn just about everything off (short of turning off the device completely) to conserve battery.

If I want a weather or news update, I manually trigger it. Because there's nothing worse than not having battery power when you really need to make that urgent phonecall.

I typically use my tablet on the weekends, and any update before then is of little use to me (since I get email, etc updates more frequently on my phone). And if the battery is too low when I awaken my tablet, I might not have that 3-hours min full charge time to get the tablet operational.
[Nexus 7 General] 2k1:
Strange, I seem to have BT audio problem, the audio keep breaking up at constant interval, like a 1-2 second pause frequently during playback. Nothing like that before upgrading to 4.3. The headphones works fine with my S3.

Updated my Nexus 7 2012 32 GB to 4.3 (unlocked bootloader and rooted) and i have to admit that 4.2.2 was working smoother in some cases then the 4.3 which i currently run.

Updated to 4.3 not via OTA, but flashed the factory image. I experience some mini lags on the soft keys, and as well while i press a button next to home one (it's the 3rd button, right one, i dont know how it is called :o ) , also when i exiting recent applications (moving them them to right) and when there are many of them i notice some black artifact on the screen when the last one at the top of the screen appears, and that was not a case with 4.2.2. (can u guyscheck if this is a case with your 4.3 N7 as well?)

Tried a factory reset few times, didnt help. Checked a freind's Nexus 7 4.3 and it's the same thing with his.

Beside this, it looks like the same as 4.2.2, didnt notice any prerformance boosts, but my 4.2.2 was working prefectly so that might be a reason, i never had any lags on my Nexus 7 before.
[Nexus 7 General] mssam:
Yeah, I agree. I didn't see much difference in 4.3 from 4.2.2. 4.3 seems to work better on the 2013 N7 hardware than the grouper hardware imo. There isn't much difference spec wise, so it shouldn't make a difference, but sure does seem like it. Idk, I actually flashed back to 4.2.2 aokp for the customization, which to me is what android is all about. Stock is not for me and I dont see the customization yet on 4.3 (on the one 4.3 custom rom I tried), but it shouldn't take too long around here for that to change...lol...
[Nexus 7 General] :
^ Yup.

I'm gonna wait for key lime pie. 4.3 fixes lag for some it seems, but other than that....brings absolutely zero new to the table....that I care about anyway. Other than the lag being better....lag I never really experienced....seems 4.3 only brings a big pile of app issues and other glitches that I don't wanna worry about.

4.2.2 is working fine for me, using PA rom.....so....if it ain't broke, don't fix it. :)

If key lime isn't my next flash....maybe 4.3 will be, when every single issue is worked out. Talking mostly about apps....and also lack of customization on 4.3. I mess with my phone constantly, but my N7 is used by others mostly.....so I don't mess with it unless I need too.

My 3 cents. ;)

But seeing as the new N7 is a msm device, devving is far easier for it. Code backports are easier because there are 1000s of msm devices in the mart.

That being said, I still think the new N7 looks like crap.
[Nexus 7 General] sgt. meow:
Admittedly that was the stupidest thing they could have done, but who says we have to rely on factory images when we've got XDA? Sure tons of people won't receive updates but the tech-conscious will usually take a peek at XDA, and install a custom ROM for it.

My 2 cents only.

I'd buy a new one if I could justify it, as it sounds nice on spec. Because of the 4.3 update, I'll probably be keeping my 2012 N7 for another year. I like ASUS quality.
[Nexus 7 General] mssam:
I understand completely. I think you are making a wise decision, JUSTIFY being the key word...lol. 4.3 is 4.3, whether its JSS15J (2013) or JWR66V (nakasi/grouper) or on a nexus 4. It's still going to take the devs a little while to sort out the kinks, but the basics like root, recovery and custom roms are there. Scotts CleanRom 4.0 is 4.3 and is nice on the grouper. Just like using the 2013 N7, except for the screen resolution and a couple of small details (like bluetooth 3.0 vs. bluetooth 4.0, etc) that fall into the "justifiy" category you are speaking of. I was just trying to give a balanced perspective as a user who owns both. Had I known better at the time and not got caught up in the hype, I probably would have waited as well. Tbh, I use the grouper with 4.2.2 aokp more than I use the stock (rooted) 2013 N7 with 4.3. It kind of irritates me. Got this brand new nexus, but development hasn't quite caught up to it yet (as far as apps and customization goes) like it is on 4.2.2. Heck, I even signed a petition to get the factory image of the 2013 N7 release! IMO, sit back and enjoy 4.3 on the grouper until that development is there. Development will be on 4.3 regardless of the device - enjoy! :good:
[Nexus 7 General] Dark Jedi:
What was people expecting from the 4.3 update? All it was just minor fixes to different areas in the software. Yeah it fixed many peoples lag issues but also it made battery life much better and when you recharge the battery it does it a lot quicker than any previous n7 is versions. Even with 4.2.2 my battery could be one percent left on the charge and for me to recharge to full it could take up to 6 hrs. Now with 4.3 I can recharge in about 1 to 2 hrs. To me that's a major fix and should make any N7 owner happy. My tablet over all seems more stable and the devs Roms are even more stable reaping better battery life.

As far as which is better I would hope the N7² ( I hate the use of the 2013 nexus 7 lol) would be better over all as its newer with updated hardware. Only time its a wash between new and old is apples iphones lol.

Only way I could justify getting a N7² is if I gave my son my N7. He is getting to that age of getting in to more advance tech stuff. Until that day comes my N7 keeps serving me well.

More than one week I'm using Android 4.3 on my Nexus 7 3G.

Сertainly after updating I've rerooted my Nexus. Updated over wi-fi. Loosed my custom recovery, still didn't install new one (don't remember is installation of recovey wiping device?)

As for me animation on 4.2.2 was exellent, so I don't see changes in it on 4.3

In most actions it's a bit faster than 4.2.2.

The best in 4.3 as for me is that with always enabled GPS, 2G(no normal 3G operators in Ukraine) and synchronization it worked 3 days (more precisely 75h) without charging. On 4.2.2 with same use worked only 2 days (46-50h).

But got a problem - now it's charging to 100% for 4h. On 4.2.2 it took 2h. Has anyone the same problem?
