Back to 4.1.2..

Dear All,

I updated on the 28th Nov in Hong Kong. The lag is gone and back to 4.1.2 smoothness. The battery life I didn't keep track since I was gaming a lot after the update.
[Nexus 7 General] phillip1953:
FYI, December was never gone from the calender. :)
[Nexus 7 General] Foggy79:
Just noticed it fails at /system/app/videos.apk.... Don't understand...
[Nexus 7 General] phonic:
You must have done something to either modify or remove that app. Did you freeze it with TiBu or something similar? Did you delete it? If so, you need to replace it with stock 4.2.
[Nexus 7 General] Foggy79:
I did remove some extra languages for the default KB, but they are all in TB available for restore, didn't remove or freeze videos.apk, it's not in my TB either... :confused:

Can someone provide me the original /system/app/videos.apk maybe? Would be thankful!
[Nexus 7 General] phonic:
Something had to have modified or removed it. I don't have a copy of the stock wifi 4.2 videos.apk, so I can't help you there.

However, you could just flash the stock 4.2 system image and that should replace it for you (as well as anything else custom in /system). That would be the fastest way to fix the problem.
[Nexus 7 General] peterk-1:
Could it be the languages are linked to something like subtitles in the video apk? I'd support phonic in the reflash. I have kept away from flashing in the past and relied on OTA but I've done the last 2 updates using downloads, Goo Manager and TWRP
[Nexus 7 General] MadPriest:
any suggestions here would be highly appreciated

i flashed clean 4.2 and then rooted and unlocked

no system modifications
[Nexus 7 General] chismay:
bump*
[Nexus 7 General] phonic:
Your build.prop file is modified. You must have applied some change to it, either manually, through an app or through some type of mod.

That error is saying that the checksum of the file doesn't match stock. Even a single character change or extra line would result in the failure and abort.

Hopefully you made a backup of the original build.prop file. You will need to restore it. If you didn't, or have no idea what change you did, you will need to either find a copy of the original 4.2 build.prop, or reflash the system image from Google, and then apply the update again.
[Nexus 7 General] MadPriest:
OMG!

yes, i changed the screen density

thank you sir!

EDIT

Successfully patched

4.2.1 running on the device
[Nexus 7 General] DrEzkimo:
no update for me in the UK, am I the only one :eek:
[Nexus 7 General] WasherUK:
Dr enzo,

Turn off wifi, go into settings/apps and find Google services framework and force stop it and clear data/cache. Then turn wifi back on and go back to settings about and try the update tab again.

[Nexus 7 General] jocke_lulle:
I got it here in Sweden last night and the update feels good.

Smooth, snappy and until now battery seems a good. Today I had lost 0,6%/h in standby over the last 11h with sync, WiFi, Google now, GPS turned on. Switching between tasks through the multitask-button (or whatever it's called :) ) feels faster than on 4.2 and I have less lag when scrolling through the widget-section in the app drawer.

I hope it's not just a response of a fresh restart...

But as I said, until now I'm really happy!:)

Anyone else has problems with SuperSU after update?

For me it says that SU binary is not installed, so I cant get SU.. It happened after update, before it was all good..

Am I missing something or what? :)
[Nexus 7 General] Rolandh:
The manual has been updated in the 4.2.1 update to the 4.2 manual instead of being the 4.1 manual like it was in the 4.2 update.

[Nexus 7 General] yogi2010:
do you guys know if Google releases a factory image for every build number, or only for the more major updates? i don't see one yet for JOP40D. reason i ask is i like to restore a pure stock system image every time i update, and i need to check my nandroids because i can't remember if i made a backup immediately after updating to 4.2.1. thx!
[Nexus 7 General] sgtpepper64:
Forced update with framework clear and reboot. Still optimizing apps so haven't actually played with it yet.
[Nexus 7 General] khaytsus:
Uh, OTA's will unroot you (change permissions etc on the su binary), this is why people use OTA Rootkeeper as it backs up the su binary to somewhere else temporarily. SuperSU's paid version has a "mode" that helps here too.

You just need to reflash the su zip from recovery, but you've probably also lost custom recovery as stock OTA's also tend to replace the script that restores custom recovery.

ie: Go through the rooting process again, minus unlocking the bootloader. ie: Flash custom recovery, flash su zip.
[Nexus 7 General] aktasch:
still needs fixing

updated with forced framework data clear method.

yes december came back at date picker.

with external keyboard ctrl+space causes reboot.

bluetooth media streaming still stutters.

random auto brightness change fixed.

4.2.1 still needs fixes. im planing to go back to 4.1.2.
[Nexus 7 General] fatfingered:
offline Maps and gps broken

I updated OTA yesterday from 4.2 to 4.2.1 and discovered that gps doesn't work offline with Maps. I varies from waiting for location to location is temporarily unavailable. I cannot confirm whether it was broken after I updated from 4.1.2 to 4.2. I was rooted under 4.1.2, then updated to 4.2 just recently (big mistake since I have shortened battery life), performed factory reset, and now 4.2.1 unrooted. I've confirmed that the GPS works and obtains a good fix with GPS Test app.

Any one else with this GPS problem? I'm seriously thinking of dropping back down to 4.1.2.
[Nexus 7 General] tobitronics:
For anyone having issues with the update failing because of missing or modified files, just reflash system.img for your device and current android version
[Nexus 7 General] gsmyth:
Apparently the factory image for 4.2.1 is up now.
[Nexus 7 General] yogi2010:
Exactly, seems much easier. That's why I am wondering if there will be an official image released for 4.2.1, or should we rely on making a backup immediately after updating? (Talking about preparing for the next update, whenever that is :) )

edit: nevermind, it's already there!

Hi, I have been waiting for 4.2.1 but it seems there still some bugs to solve, so I don't wanna upgrade to 4.2 (I'm using 4.1.2) but the upgrade notification appears every time I turn on the screen, there is a way to delete the update and stop the auto update without root?

I read something about it, but only with root...

Sorry, maybe this is not the place for it, but I only need a quick answer and don't need to open a new thread...

[Nexus 7 General] Matc21:
Got the update OTA today. I'm running the latest CWM and during the installation it automatically asked me if I wanted to keep root.

So I did and its still working.

Haven't really noticed any changes, my tablet feels very smooth and lag free.
[Nexus 7 General] chooselife:
Got my update yay.. One thing u instantly notice is that it has got its snap back.. Snapy snapy. I was struggling a lot with lag and sluguish behavior that was what most bothered me tbh i guess patience aint one of my virtues. Dunno about battery life yet time will tell havent tested bluetooth yet will do but overall pretty happy now iys looking good
[Nexus 7 General] rmm200:
Only thing I have seen that might affect performance is that the update apparently clears the Dalvik Cache and then optimizes all the apps after reboot.

Would be nice if we knew some way to manually clear that cache in the case of performance problems.
[Nexus 7 General] bkmaracas:
Was still lagging for me on 4.2.1 so have deleted the additional user and hoping that will sort it. It was v snappy after upgrade to 4.2 then went downhill with multi user. Not heard much from folk re additional users and performance, any insight helpful!

[Nexus 7 General] PhillyCheez:
In recovery... That's an option. I always clear Dalvik cache before flashing any ROM... At least 3 times.

It's also the first thing I try when having any issues.
[Nexus 7 General] johninsf:
Just got 4.2.1 for GNex and Nexus 7. Drastic improvement for me in screen transitions, lock screen and Google Now from locked. No more Bluetooth choppiness on music either. Honestly I never cared about missing December and assume it is back too.

Thanks Google for quick fix.

[Nexus 7 General] khaytsus:
Nope, he was trolling, check the date differences. It was obvious it was coming.

I just got 4.2.1 OTA, took a lot longer than I expected. Flashed with zero problems on my N7 Wifi with TWRP 2.3.2.1 automatically, nothing manual required. This is what happens if you don't fiddle with the stock system per my previous post.
[Nexus 7 General] techlifeweb:
I get errors every time if try OTA updates. I'm rooted, stock. Just gets stuck with the Android on his back, bleeding and the word Error. I've seen some zips around that are supposed to work and people have been successful with but they haven't worked either. Looks like the factory images were released this afternoon so I may have to pull the nuclear option.
[Nexus 7 General] krips2003:
Got the update. I don't know what changed. Lets see how it perform, specially the battery in coming days.
[Nexus 7 General] OmRomRom:
Can someone shed some light on battery life improvements? I downgraded back to 4.1.2 BC 4.2 was performing hate crimes on my battery.

Batter life is horrible for me ever since I upgraded to 4.2. I lose a percentage every 2 to 3 minutes.

Yeah, battery life is pretty terrible on 4.2.1 for me.

Can anyone explain why Google feels the need to limit how OTA Updates appear?

I could understand if we were talking about a small company with limited resources, but Google is hardly short of bandwidth.

Does pressing "Check now" in the System Updates menu actually do anything?

It basically just lies to users

I've waited and waited, and tried clearing the Google Services Framework (which worked for me with 4.2) and there's no sign of the update.
[Nexus 7 General] phonic:
They probably assume that most intelligent users who know/care about the update will have already of downloaded it from the URL that was posted publicly days ago and applied it manually.
[Nexus 7 General] slydew:
Hi,

I make a bad recovery of my built prop file.

Could someone share this file for 4.2 please ?

Thanks
[Nexus 7 General] Troute:
My update appeared late last night, yours will be along soon I expect.
[Nexus 7 General] tom1807:
I don't know why so much people have problems with battery life.

For me the battery life is fine, after 24 hours still 50% left.

(Maybe cause my HTC needs charging every 24 hours, so everything more is fine for me :p)

And I use it.

Emails are synchronized, Wi-Fi is 24/7 on, I surf the internet

Screen uses 36% battery, AndroidOS 29%, Google Services 13%

Tablet Idle, Wi-Fi, Maps, Android System and Mediaserver between 2-5%
[Nexus 7 General] kitsunisan:
You're being ignored because the question has been answered a few times already, people don't like having to answer the same thing over and over again when a little research will find it for you.

Install OTA Rootkeeper. Backup your root. Bam. Now, if you have recovery issues, reinstall it just like you did the first time.
[Nexus 7 General] 3d_jc:
OTA update as arrived in BE :)

Regret to say that bluetooth is still broken. Seen some improvement in general behaviour but the bt issue needs to be addressed
[Nexus 7 General] chismay:
i am searching mate i really am, i been looking through a few diff' threads but i keep on coming up with half answeres and method's

ok so use root keeper to backup root, ok so if i have a problem with recovery i use the wugs toolkit to flash new recovery? but will that work if the tab is not booting?

srry again and thanks for the reply i know this may seem like a bang ur head against a wall scenario , but yeah buddy i really have searched for this over about 2-3days since 4.2 hit just didnt have any luck with my finds.

and well.....you know i flash my phones and iconia all the time but its the whole "new device" shakes that make me re-post this question. :D

thanks again for reply:good:

[Nexus 7 General] CrazyPeter:
Really don't give a crap about a really obscure date bug (and the press that reported this REALLY need to hang their heads in shame).

However am keen to get the Bluetooth/Wifi scheduling problem fixed (streaming to Bluetooth speakers whilst streaming music via Wifi) was horribly broken in 4.2
[Nexus 7 General] robyr:
Yes, it contains changes to the Bluetooth subsystem and libraries. This is also what I am most concerned about, as it has completely ruined my experience since upgrading. Deep down, I knew El Goog would fix it, but now that its a reality, my mind is much more at ease.
[Nexus 7 General] CrazyPeter:
It's bizarre how the press went off on a whichhunt over something so mundane. Even funnier when iCretins come and tell me my calendar doesn't have December... (and I show them it does...)
[Nexus 7 General] robyr:
I thought it a bit odd that instead of focusing on issues actually affecting functionality they chose the birthday oversight as the "OMG LOOK AT THIS FAIL AHAHAHA" moment. I was FAR more pissed off about the drop in fluidity as compared to 4.1.2 and Bluetooth being nearly entirely crippled.
[Nexus 7 General] bubbleguuum:
Yes it is a shame that the press is only interested in that craptacular December "birthday" bug.

In the meantime, there are plenty of more serious 4.2 bugs in http://code.google.com/p/android/issues/list, and I see none of them assigned or marked as reviewed by Google people.

But sure someone at google had time to brag about that December bug on G+ and that they would fix it.
[Nexus 7 General] rmagruder:
As if to emphasize this point, my Nexus 7, which is just sitting there propped up in portrait mode at about 30 degrees, has decided twice in the last 10 minutes to rotate to landscape for no particular reason. Screw December....fix the crazy behaviors in 4.2 :(
[Nexus 7 General] robyr:
Well, thats not entirely true. I am the originator of some of the bug reports, and I can assure you most of them ARE assigned. Matt Xie for example is assigned to the Bluetooth issues. The main issue with trying to use that entire list to judge Google's response is the fact that there are literally 10 duplicates for every one bug.
[Nexus 7 General] erica_renee:
boohoooo

ohhh crap. this sucks.. My taxes on my home my insurance on home and cars . as well as a few other yearly things are due in December.

I protect getting December back...

On the good side. i hope they fix the quirky issues with slow down in multi profiles.And the lock screen lag. well its more like a delay....

[Nexus 7 General] mumpfpuffel:
assert(getprop("ro.product.device") == "mako" ||

getprop("ro.build.product") == "mako");

in the update script. So you won't be able to sideload it via stock recovery.
[Nexus 7 General] Cor-master:
Either way it drains too much in standby, especially when I'm out of wifi coverage. It's as of its still trying to sync while it's asleep. I can't help but wonder if it's looking for a 3G signal since their is a 3G model now. Possible oversight?
[Nexus 7 General] rmm200:
Just scanning for an access point takes a lot of current.

Turn off WiFi and synch when appropriate - like when a smart cover is closed.

Tasker makes it easy... Tasker made me a WiFi On and WiFi Off app which also toggle Synch.

That is on top of the schedule based WiFi On and Off. Mine is shut down from 11 PM to 6 AM.
[Nexus 7 General] gsmyth:
I use automate it to turn WiFi off after the screen goes off with a 5min delay and comes back on with screen on, I get a battery life of around a day and a half with 4 hours screen time, with about 30% battery remaining.
[Nexus 7 General] rmm200:
I would say my results are similar - and at that the screen uses about 80 percent of the battery.
[Nexus 7 General] gsmyth:
Same for me, I think it helps a lot, not too worried about synching/notifications as they come through on my phone which is always connected, but phone battery is helped when I'm browsing on the n7, so its all good :)
[Nexus 7 General] MarkLI88:
I had this exact same issue with losing 2-3% battery life per hour that I did not have before 4.2. I also tried everything I could to resolve the issue. I went so far as to remove just about all my apps, exchange e-mail support and turning off updating data but nothing worked. I went ahead and did a factory reset and that resolved the issue. It stinks I had to do a reset but it was worth it to have my battery life back to normal. I have since put back just about all my apps and games and my battery life is still good so I don't think it was an app.

So after disabling currents syncing and seeing a massive improvement in battery life, and killing my random reboots by uninstalling hd widgets, I think most of our problems stem from non optimized apps. We may just have to give developers time to update their apps
[Nexus 7 General] khaytsus:
I have wifi off when the screen is off... and I have the same battery life I've always had on the N7. If I take my N7 into work and it's busy and I never open it, when I get home it's at 100% battery. And not just "for the first few seconds" (ie: meter hasn't updated) but for a reasonable time, then drops to 99%, etc...

And in active use (browsing, tapatalk, using wifi, stuff like that) I see about 12% usage an hour.
[Nexus 7 General] jaspirr:
My battery life has been fine even with currents on. Should I still disable it?
[Nexus 7 General] gsmyth:
I disabled it, as I don't use it, it shouldn't break anything as its a standalone app that can be downloaded from the market.

Are we (Portuguese) so f***ing retarded that we can't even received de OTA in time? No Music, no Books, no Movies, no purchansing of any kind of Nexus on the Play Store.

We can only be a thirld world country stuck in the europe's corner, Its my educated guess.

If 10 million of people doesn't count for that matter, f***k you Google, Asus, Samsung, Apple. For sure, thats my last anoying post that i ever make about it.

Two days in on 4.2.1 and everything is tight. Only noticed change is video glitch with play store pop up dialog is gone. This was the only issue I've had since ownership. Battery life strong at 2.5 days with 30% juice remaining. All operations fluid.
[Nexus 7 General] Gongadin:
So I was still getting obnoxious amount of lag with 4.2.1, tried the Currents things and a few others, but nothing helped dramatically. I noticed that Google+ was always at the top of the battery drain list (in addition to Google services) using GSam Battery Monitor, so I disabled Google+ in the app info screen, then re-enabled it, and then I proceeded to crap my pants at how fast my tablet was again. It feels just as fast as 4.1.2 now, and getting far less battery drain. Did this last night and its still snappy as hell today. Highly recommended for anyone to try and see if they get the same results I did.
[Nexus 7 General] borrowedchief:
Still no ota here in northern Cali. Not side loading this one like 4.2 so I'm being patient. Seems like a longer delay than last ota I took though.
[Nexus 7 General] regalpimpin:
Everyone else having issues simply turning the device on since 4.2? Continues with 4.2.1

Used to be 2 seconds, let go. It turns on. Never an issue.

Now, you typically have to hold for at least 5 seconds, that may or may not work, then you may have to hold power for 10 to simulate battery pull, then again for 2-5 seconds, seems very inconsistent and differs every time.

Also if you power off, and then tap the power to check the charging status, I've had the battery icon just lock up on the screen multiple times. Requiring another 10 second hold to get it reset.

I noticed something similar. When I charged battery with N7 turned off and let it charge all night, when attempting to energize I got your situation. It happened a couple of times with 4.1.2 & 4.2.
