Hi All,
Yep, a nubie here. Recently, I have obtained a first generation nexus 2012 tablet, after my polaroid dying, and not liking samsung. to start with, I was worried of getting it, as the hardware, after all, is 5 years old, and was worried of it lagging, sort of like the iphone 4s did on IOS9. unfortunately, I was right. as a talkback user, the tablet is almost beyond useless. it's up to the point, where if I turn it off, and turn it back on, I can't use it for a good 5 minutes, the lag just takes control, and there's nothing I can do. So I started looking around, and came across over clocking. I've found 2 curnals that claim to do this on the nexus, but one is for JellyBean, and the other is for marsh mallow, and in the case of the latter, it's for the 2013 model. so my question is simply this. what curnal can I safely install on this tablet, without recking it, that will allow me to over clock? a quick search on here didn't get me far, so thought I'd post.
PS. clearing the cash partition fixes the lag for about 2 days, that is really not an option.
What you should do is install a lollipop custom ROM. I recommend paranoid Android lollipop. Also install team win recovery project. These reduce lag. Overclocking is not advised as it can already get Pretty hot under load.

Hi,
first, thanks for the reply, and this leaves me 2 questions.
1] how is the accessibility of custom RAMS?
2] if I install a custom RAM, [which I thought about, anyway] any particular reason why I shouldn't go higher, to say, android 6 or 7? thanks much.
You could go higher but performance will vary but there are custom ROMs that do let the device go higher I just can't guarantee speed ad reliability.

After receipt of my first Nexus 7 last week I can say I'm extremely pleased with my purchase and first foray into the tablet world.
What I'm not so pleased with is the lack of tablet view on many apps. The way things are displayed often leaves a lot to be desired on such a beautiful display.
As I understand it, there are several ways you can fool the UI into going into tablet mode on a system or per app basis, using either hacks or custom ROMs.
Ideally I would like to be able to flash my nexus 7 with a custom ROM like Paranoid Android, however as I am new to the scene, I thought it worth finding out:
1) How stable are the ROMs available for the Nexus 7? I've heard paranoid android does dpi per app, does this work well?
2) How many apps actually take advantage of the tablet UI? ie. if I do mod my nexus7 will it make that big a difference?
3) Are there any good reasons (except warranty) to leave my tablet running stock?

1 - Some of the ROM's are very stable, I would stick with a well known dev such as Football or Faux (yes I know faux is kernels). So paranoid android is probably a good route to go down.
2 - In my experience, only the most well known apps, such as G-Mail, Hotmail etc take advantage of the Tablet mode, but more may come when tablets take a bigger chunk of the market, which they are beggining to do so, and fast !
3 - I wouldn't leave it stock if I was you, I would definatly root for OTG etc, but the stock ROM etc is buttery smooth and I couldn't imagine using a custom ROM.
THE ONLY CUSTOM ROM THAT HAS EVER !!!! MADE ME FEEL LIKE USING A CUSTOM ROM IS ViperX, and they don't do a tablet ROM I don't think.
Hope this helps.
The M-series release of CM10 is quite stable. And the default phablet mode of n7 is quite good actually, at least for me personally.

A combo of SmoothROM and 'bricked' kernel have been fast and stable for me in the past

The Bricked Kernel dev is also hard at work on a new feature for his kernel, this apparently doesn't affect the device sleeping.

Hi guys! I just got my Nexus 7 yesterday. I'm really loving the seamless, fast experience in pretty much every app I try. However, the device shipped with Android 4.1.2 onboard, and the update to 4.2.1 has been rearing its head periodically. My question is: should I accept the update or not?
Normally I would accept it without a second thought, but Phil has said a couple times that he hasn't had a good experience with 4.2.x on the Nexus 7. I also will probably end up rooting, unlocking, and flashing custom ROM's. I say "probably" because I've enjoyed the practice on my EVO LTE for about half a year now, but I haven't found too much reason to do so on my N7 yet.
So, to update or not to update? That is the question. Also, if the answer is no, is there a way of disabling the update pop-ups? Thanks in advance. I look forward to many a good time with you guys in here.

Bought my Nexus 7 one afternoon and when it started to sniff out the wifi at home, the update was offered already. I looked around for awhile knowing how my old android "prototype" phone, Galaxy 5 went haywire after upgrading from 2.1 to 2.2. I've read a blog about the upgrade screwing up Bluetooth controllers for the nexus 7...but what the heck, I got it anyway.
now I've been using an Xbox 360 usb via OTG and I don't notice anything out of the ordinary. Dunno about the bluetooth controllers though, didn't try and won't (that's one more battery management I'm going to worry about
Don't update! It has a battery draining problem and and also a bluetooth problem (maybe even more bugs)! Wait until Android 4.2.2 or 5.0 comes out, it will be much better!

Mine works fine. Bluetooth works with my speaker (and headphones) and battery life is no different than under 4.1.*

I would update all the Apps now running stock 4.1.2 first, and, consider doing the easiest ones (for me, YMMV) by unlocking the bootloader, rooting the device, install a Custom Recovery along with Busybox.
Reboot & let it run smooth to be sure, run a TB backup and then do a full Backup (I used CWM) - and store those safely away first. Run some benchmark for scores using Quadrant Std. etc. as your baseline for reference.
Then, do the 4.2.1 OTA upgrade or alternate methods (via flashing, etc.)
Reboot & go thru initial setup as everything would be wiped clean, setup account & do the restoration (plus, root & unlock & custom recovery) and decide for yourself after using it as to whether you are happy and/or running into issues. Check your benchmark scores as well as Apps to see how they perform. Make a full Backup & store an extra copy away (mine go to the server at home.) Your next step would then be to "experiment" with various kernels & full custom Rom under 4.1.2
If you do all these, you can easily switch back & forth as necessary - or, in my case - rolled back to 4.1.2 with numerous tweaks: 720 video, Flash Player 11.x with Boat Browser & tablet UI, etc. and working OTG (with the upgrade notification disabled/turned off.) Everything else that I see in 4.2.x that I would run and use are working great under 4.1.2 as switching users on the go isn't a big deal - waiting for 4.3 or 5.0 as more annoying "bugs" would be resolved by other daring "pioneers"
The only problem I have with 4.2.1 is that audio trough bluetooth is choppy when WiFi is in use. Other then that I don't have any issues, and according to Battery Widget Reborn app my battery usually lasts for 1 day 11 hrs.
Battery use right now: 77% full, 10h 35m on battery, 59% screen on.
If you're not using bluetooth audio heavily, or can live without it (or alternatives), yes, by all means, go ahead and update.
OK, I'm gonna transform this into a poll. Should I:
a) stay on 4.1.2 and wait for a future update,
b) update to 4.2.1, or
c) do some kind of hackery (please describe in your reply)?
Like this post if you think I should STAY ON 4.1.2 for now and wait for a future update.

Thanks for locking my thread and opening this about best ROM for nexus. I will watch this thread and see which is the answer of my question.
STOCK ROM!
Honestly, on my N73G, I am liking stock. I will probably do Parandroid eventually, but the amount of trouble, vs. benefit is too high. (Am not able to make my N7 connect via adb to unlock, etc...but that's not what this thread is for )
Paranoid Android for me.
Re: ** OFFICIAL WHICH IS THE BEST ROM THREAD **
For Nexus 7 3G, I must say that Supernexus 2 is quite good. even though the customization options are lacking compared to CM10.1 for example, it's smooth and so much stable!
I tried temasek unofficial CM10.1 for quite some time before using supernexus rom; I think I have been flashing 1x of his roms, latest one on top previous ones. I only update temasek rom every 3 or so version or when there is an interesting changes. Can't afford to download everyday; slow and expensive Internet here. If only it offers delta update through cyandelta or rom manager. It's got all CM10.1 features plus many cherry picks which are epic IMO, like native USB OTG mounting, wifi / bluetooth/USB tethering. Just to name a few.
I am now waiting for supernexus 2 build 3 which should be released today, one day after its been released for S2 and S3. It's based on 4.2.2. Gonna try that for a few days. If there's any major problem, I might try temasek rom again.
I have a question: is it safe to flash just the bootloader in fastboot even though I'm using a custom rom based on 4.2.1? I don't want to return to stock because I heard it will wipe internal sd again. My N7 can't connect to my desktop computer through MTP; tried in windows 7 and Ubuntu 12.04
Sent from Nexus 7 3G using Tapatalk HD
The amount of roms out here is simply confusing.. And please don't accuse me of not doing my homework, I've spent hours reading through rom features and trying them out. None of them have the perfect feeling to me. Also, there is no performance comparision as there is with kernels.
What I'm looking for is as clean rom as possible, more impprtantly though, one that is fast(est) for gaming. Yes, I will use a kernel and oc my device, but roms i've tested still have different performance levels with same kernel settings. Rom should also have tablet ui and some fundametal configuration options such as power menu, quick settings customization etc.. Also, it should be stable enough for everyday use. Battery life is not as important, as it can be saved with app usage and undervolting.
I'm sure others have the same things in mindk, so I'll ask for everyone.
Thank you very much in advance.

I have to agree - stock and unrooted my N7 rocks. Granted, I've only had it a week tomorrow and I'm coming from Hashcode's Kindle Fire rom'ed device - which with most mods is trying to emulate the Nexus 7 - and does a pretty good job too. But my new device got the latest 4.2.2 jelly bean pushed to it a couple of days ago - no fuss/muss - and smooth and awesome it is still.
I'd decided when I activated my new N7 that I'd hold off root and modding it for a week or two to break it in, make sure that I had no warranty claims to make. With one week down all that I've missed about not having root so far is Titanium Backup.
Maybe I'm in the wrong place. Where is the, "Benefits of rooting your Nexus 7?" thread?
Maybe I'm a weirdo here but while stock ROMs are great and fast and whatnot, I'm looking for the most unique ROM! Or maybe I just need a different launcher to spice things up?
But, agreed, there are way too many ROMs that offer minimal differences...
R: ** official which is the best rom thread **
I think it's smoothroom with franco kernel
Inviato dal mio Nexus 7 con Tapatalk 2
Paranoid Android is by far the best Custom ROM I've tried. Other than ViperX for the HOX etc I think the Paranoid team do such amazing work.
Updated all the time, and never had an issue with PA.
With Faux kernel it "USED" to be amazing all round, but I've noticed recently the battery has been less and less with each update (perhaps Faux isn't keeping up)?
Franco kernel is also brilliant with PA. But yeah, for the Nexus, PA is the way to go !
Re: ** OFFICIAL WHICH IS THE BEST ROM THREAD **
The last time I tried PA, my N7 just freezes in the lock screen, quite often. Only thing I can do is reboot. At other time, when lock screen is working, there are lots of lags pretty much everywhere. I still don't understand why people still praised it until now even though in my testing it feels as if I'm holding a bomb ready to explode at any time.
Even people in the nexus community can't escape the "hype" and placebo effect of roms or tweaks or even kernels.

I love stock and stock kernel on my N7 because it gives me the best battery life plus performance. I can run many applications flawlessly. No hiccups or lags. To be fair, i have only tried MiNCO ROM, paranoidandroid, and CM 10.1. I liked the customizations and the tweaks that were implemented to improve it but it just wasn't for me.
I flashed back to stock a few days and I'm going to camp here for a while.

I'm a pretty big fan of dirty root box IMHO. I think it looks really slick and gives pretty good performance and tons of customization. Paired with Franco kernel it also gets great battery life.
PRIME D02 is the fastest ROM I've tried, by far.
It is a clean ROM concentrated on improving performance, it doesn't add a lot of features which also can be added afterwards to your taste (for instance if you want a PIE menu you can add LMT Launcher). But you can select extended desktop (full screen), you can customize the navbar buttons and settings, nav ring, status bar, and quick settings (swipe down from the top right of the status bar).
If you use this rom with its standard kernel, make sure to install Trickster MOD and adjust the setting 'CPUQuit Power Management' to 'RUNNABLE' (swipe to the last tab, and don't forget to press 'V' on top of the screen to activate, and enable 'set on boot'). This is needed to get good battery performance, otherwise 3 cores will run at high speed. You will still get the super fluid performance.

Isn't anyone using AOKP? I switched from SmoothROM and never looked back. SmoothROM was nice, much better than stock, but the customization and stability with AOKP simply incredible. I'm using a 4.2.2 nightly right now, couldn't wait for the Bluetooth fix and haven't had a problem yet.

I've got a 16GB Nexus 7 that barely ever leaves my desk drawer anymore. My unit is from the batch that becomes extremely laggy if less than 4GB are free, takes a long time to charge, and loses 50% a day in standby (even with Wifi Off and nothing syncing). I'm positive the unit is faulty somehow as if all Nexus 7s were like this, there is no way they would have reached this level of popularity.
So now for the question:
What should I do with this thing? Is there an alternative lightweight OS I can flash to it? Can I turn it into a Kindle Fire or something? As it stands now, it is an expensive paperweight.
There are several things you can do to possibly increase the performance and battery. For starters, such as flashing a light weight power saving ROM and kernel then adjusting its frequency, voltage and governor. Afterwards try this - http://forum.xda-developers.com/showthread.php?t=1971852

When is the last time you did a full wipe?
I've tried everything. Numerous wipes, numerous roms/kernels (slim, CM10, PA, etc.). In the end, the same lag and slowness always ruins the experience. I've pretty much given up on using this thing as my primary tablet. I'm now trying to decide if I should sell it, give it away, or use it for some other purpose. I've thought about flashing a bare bones version of CM10 with no apps and using it primarily as a Kindle Reader..

Guys,
I picked up a second hand Nexus 7 yesterday for a really low price. I had no intention of a purchase but sometimes the price is so low you can't say no. :angel:
The N7 is currently on 5.1.1 and has very inconsistent performance. 1 action will be slow, then the next few quick. (1 day of usage after factory reset.)
I'm looking to give this tablet to my 9 year old nice and was wondering if stock 4.4.4 has better performance? As its for a 9 year old, I'm looking to keep everything totally stock.
Thanks in Advance. :highfive:
Honestly, my N7 ran fastest with the OS that originally came on the device, 4.1JB. Assuming you don't want to go back that far, 4.4.4 would be the next best choice.
There are a couple of good 5.1.1 custom Roms that are fairly smooth, but since you only want stock, stick with 4.4.4

If I was going back further than 4.4.4, I'd probably go back to 4.2.2 as it really impressed me on the nexus 4.
Take your point about 4.4.4 being the best recent os though. How would you rate 5.1.1 if we would say that 4.4.4 is 100% speed?

Trimmer?
So far I have no idea why or how it works, but I followed some advice I read in this forum and installed a "trimmer" application. I manually started a "trim" operation, and after that the device became noticeably more responsive. Even in case that this is just a placebo effect, I am much more satisfied with the tablet than I have been before. You might just try it, the app comes with no cost, and if the device is usable afterwards, you can pass it to your nice niece. Otherwise you can try to install a different, or even older, operating system.
adeelraj has a point. It seems your main qualm about using a custom Rom is the complexity of its added features. BSZAospLP is pretty much stock AOSP, so it should behave pretty much like the stock ROM.
And Ahkah also has a point. My brother's N7 was exhibiting similar symptoms to yours. I formatted his /data and /cache partitions, and then ran that Trimmer app (root) and that fixed his random slowdowns problem.

Thanks Ahkah,
I haven't used the Nexus 7 much since I bought it. Theoretically, the fs trim issue shouldn't impact performance yet. I've just found the performance being really inconsistent on 5.1.1. i.e. one command fast and smooth and the next has lag.
Someone is borrowing the tablet at the moment and I will probably try 4.4.4 when I get it back.

Well, I heard enough bad things about the stock LP ROM, that I went straight to the XenonHD 5.1.1 ROM. I can tell you that outta the box (without making any speed optimizations), it was running at 85% the speed of my previous 4.4.4 ROM (SlimKat).
I had Lollipop on mine and Lollipop+3 years worth of junk=a BIG surprise. So I rolled it back to 4.4.4 and it was very, very smooth. Then flashed one of my backup zips for Lollipop (made when no apps were installed) and it was still laggy as hell.
So conclusion: Lollipop sucks ass on this thing.
