Howto fix performance problems w/ 4.2 update - Nexus 7 General

Hi folks,
Like many of you, I ran into horrible performance after the 4.2 OTA. I was running an essentially stock image with superuser installed. Some people mentioned that restoring to factory from the images at https://developers.google.com/android/nexus/images#nakasijop40c was the only real solution.
I was hoping to avoid having to reinstall everything by following that, so I did come across a stop gap solution.
1) Download the image from that URL.
2) Untar it.
3) Unzip the zip file within
4) Download supersu (standard superuser has some problems w/ 4.2 I noticed too)
5) Reboot into fastboot mode
6) Flash system.img via fastboot (sudo fastboot flash system system.img)
7) Reboot into CWM
8) Install supersu
9) Clear /cache
10) Reboot
After doing that, it restored the performance to my pre-4.2 update without having to wipe everything.

What "performance problems"?
.oO(I must have bought another tablet...)

It doesn't seem to happen to everyone, but there are a fair number of people i've been seeing who hit this problem too. You'll find some posts where people did read/write speed tests before 4.2 and after and it was significantly worse. Causes lag throughout the OS.

SuperSU, in that it roots, causes crippling lag on secondary users.
I use multiuser a lot, and that is only possible because I have my nexus unrooted. No idea if Superuser has the same problem.

I second the disable synch on Currents. Pulse is far better - for me - anyway.

[Root] Replacing Superuser app with Super SU by CF

Super SU by CF
SuperSU is the Superuser access management tool of the future
Features include:
- Superuser access prompt
- Superuser access logging
- Superuser access notifications
- Per-app notification configuration
- Temporary unroot
- Deep process detection (no more unknowns)
- Works in recovery (no more segfaulting)
- Works when Android isn't properly booted
- Works with non-standard shell locations
- Trusts ADB connection
- Always runs in ghost mode
- Wake on prompt
The Pro version additionally offers:
- OTA survival mode (no guarantees)
- Full color-coded command content logging (input/output/error)
- Per-app logging configuration
- Per-app user override
- PIN protection
Who, What Why ? - said by CF
As you may know, I make a lot of apps that use or require root. I also release rooted kernels. I run into a lot of issues with existing Superuser tools. More importantly, a lot of my users run into these issues as well and then email me about it. So I decided to do something about this. Doesn't mean these were problems you have ever seen, or will ever see.
And thus, I have written - pretty much from scratch - SuperSU. I have taken the su binary command line parameter parsing from Superuser, to make sure that is compatible. Aside from that, it is completely rewritten, because how I wanted to do a number of things was incompatible with the existing codebase.
This is not a stab at ChainsDD, or his skills. He has done great work and will no doubt continue to do so, however, I felt the need for some of these changes, and thus made them. This is an early release, so I expect there will be some unforseen issues somewhere.
From now on, all CF-Root and Mobile ODIN Pro (EverRoot) releases will be built around SuperSU.
Please note that SuperSU is not hardened-security-tested or reviewed, and may be exploitable (... as may other solutions ...).
Install :
Flashable Zip v0.93
Market :
Lite
Pro
Note : Pro is key only, you need to install lite version first.
If you install from market, you will have two superuser, remove older one with system appl remover, or any other application can perform same job.
Remember, if you remove older first without installing newer one, you will lose Root n newer won't run.
One more thing market version will be regular application, so hard reset can delete it. So better install with flashable zip, to make it system application.

Thanks a lot doc. Gonna give it a try.

Sorry to say but this belongs to General Section.
Nice one, Dr.Ketan.
Perhaps your fine installation instruction could also include this:
"Superuser (the old one) is a system app and should be removed from /system/app/ folder using Root Explorer, ES Eplorer with root permissions, or similar explorer app. Titanium Backup does not show Superuser in its app list, and therefore cannot remove it."
Otherwise you'll be swamped with Titanium questions.
This is modding
any thing android Mod, should be better place under development.

Very Slow Boot Up Following Switch to SuperSU Pro
My Note is running rooted stock ROM with Franco.kernel v6. After installing the SuperSU v.75.zip with CWM and installing the Pro key, and removing Superuser.apk my Note is VERY slow to boot up. It took less than 1 minute immediately prior to SuperSU and now takes 5-6 minutes. It runs wifi and mobile data and sync together EVERY time it boots. It never did this before. It also runs "Media Scanning 6-8 times before it finishes booting.
I'm not complaining, just informing. I realize that this is a new work in progress as posted in the OP post #1. Is anyone else having these issues? If not, any suggestions to correct these problems? I have tried clearing Dalvik and cache partition through CWM app.
Thank you for any help and/or advice.

what you said was true...it slows up booting...but what i did was, in supersu app, i selected grant as default and there is no need for prompt...after that, booting as speed up!
I actually found my own solution as you were posting! Thanks for your help, grgsiocl!!! I did leave default access set to PROMPT though as it will only show the first time until i grant permission.
MY SOLUTION: I unchecked the show Notification Toasts, rebooted and total boot up took 50 seconds!
Sorry for wasting space in this thread!!! Hopefully, anyone else having similar trouble will see this.

How to delete an android app without booting to ICS

I installed Task Changer Pro, to go with WebCM9, for some reason when ICS loads Task Changer Pro locks the screen from any touches, I can however lock and unlock the screen using the power button.
How Can I uninstall the app without using ICS.
Edit1-
Method to fix in post 5.
Easy way is to flash a new ROM
Sent from my PG86100 using XDA
No that is the hard way.
I want to boot in safe mode.
(Safe mode prevent non native apps from loading) I just don't know what button is used to get into safemode on the Touchpad.
You can always ty and mount it from within webos and delete the app manually ?
Sent from my cm_tenderloin using xda premium
Thanks, I tried a few ideas to get rid of the culprit app.
1. Safe Mode - Didn't Work
Safe Mode on TP doesnt seem to work, perhaps due to the lack of awareness by the tenderloin devs and or a mismapped key.
2. ADB into the device and remove the apk (CM9 ADB Drivers)
3. Mount in WebOS - Didn't know how
4. Perform a factory reset - Didn't want to resort to this
#2 worked for me after about 2 hrs of research and trial and error, even then the app was not named "TaskChanger.apk" it had the dev's name as the app.

[ROM][NANDROID-BACKUP] minusculeShield 1.0

minusculeShield 1.0
So after some time, I decided that the 4.3 update is worth doing slight modifications, even without the native Shield Services and PC Streaming able to be done remotely. I have gotten used to using Limelight anyways, so I decided to update my basic modified stock Shield ROM
First, I updated to the latest OTA 68, then went from there, the features are as follows:
- Two versions of the ROM, one with OTA and one without
- Includes a alternative Calculator (RealCalc), Zeam Launcher, Adblock, Xposed Framework (Along with an Xposed Module for adding a Play Store link to App info, and GravityBox for various system tweaks), MX Player, and ES File Explorer
- All but the most essential "system" apps are removed
- All "Gapps" are using Slimroms 4.3 Minimal Gapps
- Koush's Superuser/Superuser Binaries pre-installed
Same installation process as 0.5, excluding need to select Advanced Restore, you can restore like a normal Nandroid without specifying partitions
As always, make sure you wipe System, Data, Cache, and Dalvik before installing
If you have problems with the OTA-exempt version trying to OTA, if it prompts you, it will do it once, and once you "apply" the update (which it will never actually apply) the notification will go away
minusculeShield 0.5[Nandroid-Backup]
So, this is not really a ROM, but a Nandroid backup of my system without any partition but "/system."
This is almost as stripped down as the stock Shield ROM you can get. I have removed all but literally the most essential apps, and also removed the OTA functionality.
The idea for making this was that I couldn't stream remotely anymore since OTA 63, which I promptly set out to fix. I soon realized it was a problem with the Android side of things, as using it on 4.1.2 or 4.2.2 with their respective apps for that release seemed to work fine. OTA 63 (and 64, which is basically the same release, just for those who couldn't install 63) made the local streaming much less productive, as I immediately noticed lagspikes and a load of other problems, which I had never encountered before.
So, in a basic sense, this backup after installed, keeps the ability to stream remotely without troubles of performance or re-connection problems, uses a much more lightweight version of Gapps (Slimrom's version to be exact). It is based on agrabren's TweakerROM 1.1.0, which is a 4.2.2 base, and uses the original TegraZone Dashboard. It again removes OTA, so updating is not an option.
So, when you do install this backup, your internal "/sdcard" storage should no longer need the "nvidia" and "shield" folder, and you can delete those. They will most likely be recreated by some Shield services.
So on to installing and basic rundown in-case you past the above message and just want a bulleted list:
Installation:
Assumes the following:
1. Unlocked Bootloader
2. CWM installed
Installation procedure:
1. Download attached ZIP, extract to your internal SD card ("/sdcard") using the folder structure of "/sdcard/clockworkmod/backup/<extract contents of ZIP here>"
2. Boot into CWM and select backup and restore
3. Choose advanced restore
4. Choose minisculeShield, then "system"
5. Factory reset, wipe cache, data, and dalvik
6. Reboot and enjoy
Information on changes to original 4.2.2 ROM and other info:
- Removes OTA system
- Improves performance of streaming using original Dashboard, Shield Services, and Shield PC Streaming applications
- All but the most essential "system" apps are removed
- All "Gapps" are using Slimroms 4.2.2 Build 8 version
- Koush's Superuser/Superuser Binaries pre-installed

Version 0.5
Version 1.0 (OTA Enabled)

I'm glad, I thought people would be trampling each other to get a hold of some sort of fix to the remote streaming issue. I guess not. I know I was SUPER disappointed by the latest update for that exact reason.
Let me know if you have any problems, questions, or concerns. I am very new here, but I have been working with Android for almost as long as it came into existence. I started with Android 2.1, so I have learned a lot. I'm also a Unix (mainly the Linux variety) guy, so that goes hand in hand with Android.
I still get notification prompts for ota.

This prompt is a one-time thing, if you attempt the install it will fail and never prompt again. I attribute this to a probably data not being cleared for the actual OTA I removed before doing the Nandroid, but I assure you, I have never gotten it again, and never had to install it past that. Basically, if you attempt the install, it will not restart, but rather just disappear, and even upon restart will just boot normally. Let me know if you've tried that what happens, as I still am using this Nandroid, and since I did indeed attempt (and fail) installing that OTA, it has never prompted again, and stayed where it was during Nandroid in terms of system apps and such

Is it me, or does the new GFE render the PC running it as "Busy" regardless of the version of the Android side? It was working prior to the GFE update 1.7.1.0, I just had to use the version of the PC Streaming, Dashboard, and Nvidia Shield Services apps in this Nandroid. It seems Nvidia has found a way to render it "Busy" the same problem I had before, no matter what ROM you use
Please test, and let me know, as I will have to find another way

[ROM/A1/Recovery][Wifi+3G+TMobile][4.4.4/2.8][Oct 27]Omni Based Rom and TWRP

Summarized Standard Disclaimer: use at your own risk. I use it at mine.
*Full wipe recommended if coming from another kitkat rom*
MAKE SURE TO HAVE A BROWSER APK. THERE IS NO MORE STOCK BROWSER. For firefox see below.
My personal build "Diamond Rom 4.4" is based on omnirom with the following additions:
CM Calculator (the newly redone one they're proud of)
CM File Manager
CM Wallpapers
Bash shell
Nano text editor
Powertop
Koush's full featured open source superuser (and it's INTEGRATED into settings :cyclops: )
Carbon rom blue balls wallpaper
Cyanogenmod port of 2 column settings adapted to Omni rom.
Omni floating window
I've added a few of my personal touches which include
Batter circle color changing: green 100%-51% yellow 50%-16% red 15%-0% This was my favorite I9000M framework-res mod that I've missed since switching to CM7.2 way back.
Killed lock screen music full screen (personal privacy thing when riding public transportation)
Disable android external storage management: messes with ext4 formatted hard drives or multi partitioned hard drives. Use the unix style mount command
Disable hardware keyboard on boot: disabled but not removed. You'll have to manually turn it on
Removed camera sounds
Disable SELinux at the kernel level. It's even disabled on my laptop/desktop at the kernel because it seems like it's more trouble than it's worth.
Put the dalvik cache in the cache partition. Don't waste the data partition for it. :cyclops:
And of course, comes bundled with my A1 kernel :cyclops:
Every thing I've tested: camera, youtube hd, sound, gps, usb otg(use manual mount command) etc work.

Can't mount ext4 media: kill the e2fsck process assuming you safely removed the media before sticking into the tablet.
(Below this is optional)
(Android device manager does have legitimate uses. However, please read and consider the following paranoid but realistic fantasy:)
Completely disable android device manager: By only going to Settings->Security->Device administrators and un checking "Android Device Manager" this doesn't completely remove the ability for google to send in commands to your device. Go to the google play store through a web browser, choose android device manager, and try "ringing" your device. To my horror, my tablet started to ring as if it got a phone call. I don't find it acceptable that gapps gives google a way to setup a remote command and control operation. In any other operating system this is considered a back door or virus.
To close this back door install Xprivacy. Enable system apps to be modified. Look for the entry (should be highlghted in red to indicate a system app) "Google Account Manager, Google Backup Transport... (lots of items here) ...Google Services Framework". Check mark Notifications and open its menu. Check mark the items in red. These are cloud to device (c2d) permissions which do exactly what you think. While not necessary, disable identification too for good measure. This disabled the ring feature on my tablet which means android device manager should no longer be able to send in commands. I don't have the guts to try the device wipe feature but it should work too. Do not disable location otherwise google maps won't be able to find you which means no gps car navigation.
See this post about building from source. I use a different, simpler trick for prebuilt chromium binaries. Fear not, they are source built but only when there are real source changes. They're just recycled in between to save 90mins/build of time.

Thank you very much!
Hi AAccount,
thanks for your 4.4.3 ROM, sounds promising ... however, what about the graphical glitches on that vesion? I always went back to ROM version CM10.2/SGT7 as this seems to be the latest one without those glitches (last version I tried was Nameless ROM version 4.4.2 where they were still visible ... and annoying).
Thanks in advance,
mistersixt.
Great job!! Runs fast without bugs and glitches, only youtube HD...
The best kitkat rom!! Thanks !
Enviado desde mi GT-P7510 mediante Tapatalk
Best kitkat rom. I have some glitches. It is not as smooth as cm10.2 so i am going back to cm10.2.
What graphical glitches do you mean? I think ever since omni fixed the screenshot way back most graphical bugs have been ironed out. By youtube hd do you mean it doesn't play or can be laggy? If you mean laggy I read on wikipedia the GPU video decoding on the tegra2 sucks. That's a hardware problem.
3G build and new recovery coming later today. I cheated the chrome renderer build process by copying all the freshly done ones from the wifi only output folder.
My github is now fully up to date with all the appropriate omni repos forked with my personal touches whether it be the audio blob fixes or little things I like.

With all ROMs starting with 4.3 it looks like if a flash of lightning goes from one corner to the other (my wife is saying it looks more like a scratch) for maybe 100 ms, this happens quite constantly though, every minute or something. Also, in some games like flappy bird the application gets stuck for maybe 100 to 200 ms completely (every 5 to 10 seconds maybe) before it continues, this makes playing games unpossible (temple run is another good example).
With 10.2/SGT7 this does not happen ... for whatever reason.

I added instructions. There's no really preferred gapps package. I just like that one because it's the smallest one that gets the job done. There are some gapps packages that are bigger than the rom which I consider bloated.

I get these randomly sometimes but not often enough that I would consider it an issue. In angry birds it's an issue but if you go to Settings-->Developer Options check mark "Force GPU rendering" and "Disable HW overlays". Then you can play angry birds at least without the lightning.
And now for an important question
I have a script that puts /data/dalvik-cache on /cache/dalvik-cache as it was way back in android 2.2 froyo. Even though our tablet shipped with android 3.0 and my I9300 S3 shipped with android 4.0, Samsung seems to have been very sloppy and left the /cache partition huge to accomodate the froyo standard. This is a waste of space that will never be used. The cache paritition is 0.5GB. Is it OK if I include this script as a boot script? Is 0.5GB/500MB enough for most peoples' dalvik-cache? This will free up that space and add it to the internal sd card.
Great room, thanks! Everything working OK during the first hour of use

Thanks for posting this! Great ROM. Only problem I'm having is the APN settings are blank for my 3G tablet (P7500). I input them manually and everything works, but normally they are preset.

I get these randomly sometimes but not often enough that I would consider it an issue. In angry birds it's an issue but if you go to Settings-->Developer Options check mark "Force GPU rendering" and "Disable HW overlays". Then you can play angry birds at least without the lightning.
And now for an important question
I have a script that puts /data/dalvik-cache on /cache/dalvik-cache as it was way back in android 2.2 froyo. Even though our tablet shipped with android 3.0 and my I9300 S3 shipped with android 4.0, Samsung seems to have been very sloppy and left the /cache partition huge to accomodate the froyo standard. This is a waste of space that will never be used. The cache paritition is 0.5GB. Is it OK if I include this script as a boot script? Is 0.5GB/500MB enough for most peoples' dalvik-cache? This will free up that space and add it to the internal sd card.

Many thanks for this!
"Disable HW overlays"- for some reason this setting does not stick between reboots (not your ROM problem- it happens in all devices that I've ever seen). Is there a way to apply it automatically during or after boot? Such as in a script, or init settings etc?
Regarding the Dalvik cache, is there a way to know how much space all my installed apps + system are currently using?

Go to the CM File Manager --> Settings --> General Settings -> Compute folder statistics and check mark that box. Also in the same area be sure to set access mode to prompt user mode or root access mode. Then, go to /data and hold dalvik-cache folder until get a menu and choose properties. The size will show up under "Size: ". Mine is 208mb.

238MB here. Maybe a quick poll can help gather info on how much allocation must users are using?

Same around 2xx mb. I'm fine with it, since the 400mb in /cache is wasted anyway.

I have the same problem with 8.4. With 8. everything works fine

Cast version works perfectly fine.
Any chance you could include OmniSwitch in the next build @infrag? And possibally an option to use that as default recents? If not, no problemo!

Anyone else having problems with their proximity sensor?
updated modern, still getting invalid mmi
I was getting loads of chinese text through with the ussd/mmi system like trubul here, infact I made a thread about it. And also the loss of ussd code functionality with "invalid mmi code" error that he described.
Azlanhu says:
"had the same problem. Apparently, u need to flash the new modem/baseband I9305XXUFNI3 . "
Trubul seems satisfied with the solution, however when I flash the modem linked, whilst it sorts out the Chinese text, I still get invalid mmi codes all the time.
Am I missing something? Is a baseband something separate I need to flash, and if so where can I find it. Or something else?
Cheers.
I9305 (d2lte) SlimKat
I would like to know is it possible to install in Germany the SlimKat D2LTE version, or it may thereby lead to problems?
SlimKat vs SlimSaber
I know that Slim Saber Saber with the mod has been created, but I do not see quite the difference, so I would like to know your opinion of what you think are friendly for BATTERY?
Google Play No connection issue
My i9300 is stuck in a no connection issue in all the gapps, tried everything, clearing cache, data and even hard resetting
I have a rooted Slimkat 4.4.4 build8.0, stock Slimkat's kernel
Sorry for my bad english
SlimKat 4.4.4 8.6 Camera issue
Really nice rom - well done! The only issue I found so far on i9305 is that the camera does not work - it crashes when trying to access it. Even installed Camera MX but that freezes the phone completely on a black screen and a restart is required. I've noticed others were having the same issue. Are there any fixes for this?
Anghirrim said:
Hi, camera used to be fixed by just going back into CWM and wipping cache + dalvik cache. It used to work for me.
For the DPI, did you activate the root in the security option. I think you need it.

I have the exact same issue with my camera. It was working before V8.6 but now I can't seem to fix it anymore.
No wiping of cache, even clean install (with format of /system) didn't do any good.
I also tried to extract various camera2.apk packages from older versions but I always run into the same problem
when starting up the stock camera app (other camera apps result in a freeze of the entire phone).
Unfortunately this time this does not solve my camera issue, and I assume it's the same for the others here. I even tried to replace the camera2.apk with various apks from older releases but it didn't help either. And if I try different camera software (apps) the systems just freezes completely. Any ideas?

Install CMFix from the Play Store, read the Important Instructions on the app's Play Store page & click the link to download Temasek's Restart Camera app. Do not open CMFix - first install Temasek's app & grant it SuperSU root permission. Then place a shortcut to Camera CMFix on your home screen instead of the link to the 'normal' camera. It's worked for me on all SlimKat & SlimSaber versions & with CM11.
woww thanks you
Is there a way to return to the AOSP recent apps window? The only thing I don't like on this rom is the recent apps window and how it looks and also the fact that there's a gesture instead of a clear recent apps button

Thanks for the support. I already tried this twice though (and yes I followed the instructions to the letter) but I get the same annoying "unfortunately camera has stopped"
popping up when I then start the CMfix app.
I'm just not sure if this is a ROM issue or if this might be due to a conflict between my apps. Maybe I will try a clean wipe, of cache and system, then reboot into ROM
and see if the camera will work or not. This should tell me if it's ROM related or not.
I hate to restore everything afterwards though and to return to the issue for further investigation
I'd be glad to hear if someone else found an alternative solution!
Have you enabled root access? I would re-install the ROM having formatted system & cache & wiped dalvik and only then tried a complete wipe if that didn't work.
Finally got the camera working again

Yes I have, that was not the problem though I finally got it to work again, here's what I did (in case anyone runs into the same issue):
1.) Install CMFix from the Play Store + download & install Temasek Restart Camera (with root permission)
2.) Run camera CMFix --> still got the "can't connect to camera" error message
3.) Reboot to recovery, wiped dalvik, wipe cache partition & wipe data/factory reset
4.) Restored apps & system data via Titanium
5.) Run "Restart Camera" and CMFix again --> This time the camera did work again :good:
6.) Tried other camera apps --> camera is working just fine now --> uninstall Restart Camera & CmFix --> camera is still working
Also one could try installing a different GAPPS build - there is a stable one from mid September and various betas up to a day ago,
maybe that might be another cure (or cause) to fix the camera bug.

Hey! Tried this and the other mentioned stuff several times but still no success... has anyone heard from other ways to get the cam to work? or maybe an alteration of the quoted post?
