This post will help you out. But DO NOT use TWRP 2.8.4.0. It has a bug in it which will say there is no OS installed.

https://plus.google.com/104384867235711140238/posts/7No16fUQaFz

** edit** TWRP 2.8.4.1 is released and it fixes the problem (bug) of 2.8.4.0.
[Nexus 7 Android Development] Smallsmx3:
OK.... But earlier versions of twrp are fine
[Nexus 7 Android Development] SkOrPn:
2.8.3.0 runs perfectly for me. I am not going to tempt fate on 2.8.4.0 though. lol

Is it possible to return to stock DPI ?

I usually use "texdroider_DPI" from playstore but I have a force close each time I try to use it ith this rom

How can I chang ethe DPI and what is the stock DPI please ?
[Nexus 7 Android Development] SkOrPn:
There is no stock DPI, all ROMs have their own idea of what DPI should be used. EDIT: I think the DPI on the Nexus 7 when it first came out was 213? But I may be wrong. Try several different ones until it feels just right to you.

Open Root Explorer.

Go to /system.

Click on Mount RW.

Grant Superuser access to Root Explorer.

It should now say RO (meaning you now have full RW read/write access).

Look for build.prop and long press on it and open in a text editor.

Scroll down to ro.sf.lcd_density=182

Change the value to anywhere between 180 and 240. I like 200 myself

The lower the value the higher the density and thus more items can be put on the screen.

Click on the Menu button.

Save and Exit.

Reboot.

Good luck...

What's everyone using for ad blocking on this ROM? Adaway does not work, neither does adfree. Can't handle all these ads.

-(.stryker.originals.)-
[Nexus 7 Android Development] SkOrPn:
You can try MoaAB or ABP. Mother of all Ad Blocking works good to eliminate almost all ads, but after a few years using it I find it hard on my devices processor and really slows down the browsers. Adblock Plus (ABP) uses a proxy, which is a better way and a faster way but some do not like it for what ever reason. I'm using it without problems and yes it does let some unobtrusive ads through the kinds that don't bother you much.

Try both of them though, but not at the same time. lol
[Nexus 7 Android Development] khaytsus:
Adaway works just fine. When it says it can't write the file to system, have it create the link. Works.
[Nexus 7 Android Development] secret.animal:
I use lucky patcher
[Nexus 7 Android Development] treesurf:
Adaway working with no issues here.
[Nexus 7 Android Development] mrpkarthik:
Hi,

Please help me..I have tried the above steps ,but after "TWRP menu, hit "Mount", and "Enable MTP" if it is not already enabled" this step,

I cant access the Internal Storage in Windows 7..Please help me fix this issue.

---------- Post added at 08:33 AM ---------- Previous post was at 08:24 AM ----------

The Problem was Solved..:good::good::good:

I rebooted recovery and problem was gone..
[Nexus 7 Android Development] ZEII:
Excuse me. My N7 is data/cache f2fs not all f2fs, can I use a f2fs version?

Thanks you.
[Nexus 7 Android Development] khaytsus:
"all" f2fs just means /data, /cache, and /system must be f2fs; so just format /system (and /cache if needed) f2fs before you flash.
[Nexus 7 Android Development] sTl2yk3l2:
It works now. I had an outdated version of adaway and it was saying I had to switch to system/data/data, then it would get an out of space error. But its all good now. Thanks.
[Nexus 7 Android Development] reebz:
Perhaps a noobish question. I have been using this ROM for a while now, but the freezing and lag is starting to just annoy me too much. I'm using the f2fs version. Can I just install a KK ROM, f2fs version. Obviously I'd clean flash, but I don't need to worry about issues downgrading to a KK ROM? Thanks for any advice..
[Nexus 7 Android Development] Smallsmx3:
I'm having issues. I format data, convert to f2fs and when I go to transfer files over from my computer my computer doesn't recognize my n7. I've tried everything

---------- Post added at 04:59 PM ---------- Previous post was at 04:47 PM ----------

Seems like I'm not the only one with issues.... So reboot recovery and pooof your computer started recognizing your n7?
[Nexus 7 Android Development] Reiven89:
I love this ROM but I had to switch to XenonHD due to working camera....hope one day I can come back to freak slim with working camera
[Nexus 7 Android Development] mrpkarthik:
Yes Just Switch Off ..

And Reboot to Recovery .. Then Your System will detect Internal Memory.. Also "Enable MTP" in Mount .

Hope it will helps you.:good:
[Nexus 7 Android Development] SkOrPn:
Or download files directly off the internet on your computer, but do so directly to a flash drive and then use OTG. No chance of any problem then...
[Nexus 7 Android Development] skrewie:
Smooth and good battery... No root ??!!?! Now i cant get in to my recovery and why is there no advanced reboot meny? That should be basic stuff to have in a costum rom theys days !?! Or is it lollipop thats make it hard to do this **** ?

Any way great rom !
[Nexus 7 Android Development] AirOne70:
Isn't this what you want :

And did you flash SuperSU?
[Nexus 7 Android Development] skrewie:
Thanks alot!

NO where can i find superu.zip?

Edit》》 is it this one http://download.chainfire.eu/supersu ?

V 2.44 ?
[Nexus 7 Android Development] SkOrPn:
Yes, that will work just fine.

Has anyone tried doing fstrim lately? When I try to TRIM the device it says my Nexus 7 does not support it. Anyone else?
[Nexus 7 Android Development] Jump1ng:
Don't think the GUI works with ART runtime. I been running it by opening a terminal window then su and you can then run like

fstrim -v /data

fstrim -v /system

fstrim -v /cache

I usually only get anything trimmed on data but when I run it always run all 3 :D
[Nexus 7 Android Development] SkOrPn:
OK, all three failed for me.

root@android:/ # fstrim -v /system

fstrim: FITRIM: Inappropriate ioctl for device

All three give me a "fstrim: FITRIM: Inappropriate ioctl for device" error

EDIT: Changed to a different kernel but getting the same error. Interesting... Oh well, its running really good so I am not interested in diagnosing any further, lol.
[Nexus 7 Android Development] Jump1ng:
Weird I have done it on different kernels maybe there is something in the Freak-SlimLp builds then as it works fine on my stock google OS.

Sorry I couldn't help you out mate.
[Nexus 7 Android Development] ichigo_kurosaki:
Anybody here tried the tegra 3 kernel with this rom?
[Nexus 7 Android Development] khaytsus:
You're probably on f2fs, it does not need/do trim.
[Nexus 7 Android Development] SkOrPn:
OK, thanks. Then something else must slow it down after a few weeks of great performance.

---------- Post added at 06:02 PM ---------- Previous post was at 05:50 PM ----------

Yeah, and it did not boot for me. I tried 35 and 37.1 and neither booted for me. I flashed over a73 all-f2fs though so not sure if that was ok or not, but I see no reason why it wasn't.
[Nexus 7 Android Development] TheDickster:
The Tegra 3 kernel doesn't have F2FS support built into. That kernel is very basic with the idea of other devs to add features to it.
[Nexus 7 Android Development] SkOrPn:
OK, I thought I saw quite a few running it with f2fs, but maybe not. Or they converted them themselves, lol. Thanks
[Nexus 7 Android Development] carlfinity:
Yes, it does have F2FS support. I'm using it well on Freak's F2FS version. You just need to look for the correct agnostic file that is posted by one of the members in there. You'll need it for the tab to boot.
[Nexus 7 Android Development] ichigo_kurosaki:
Hmmm..a friend and a fellow slimlp user (he is on f2fs and i'm on ext4 version) and he said the tegra 3 kernel is awesome and far ahead of google's or any lollipop kernel..but i am in doubt whether it has kexec-hardboot support as i am currently on multirom (i need a nonlollipop rom for freedom to work.:D ).
[Nexus 7 Android Development] abrahammmmmmm_:
[MENTION=4353163]Jump1ng[/MENTION]

All three seems to work for me running leankernel 5.2, seems to be kernel related as before I was running oxydo and had certain problems
[Nexus 7 Android Development] SkOrPn:
And you are using F2FS on all three partitions?
[Nexus 7 Android Development] abrahammmmmmm_:
Yes, I've been using full f2fs for a while now and don't plan on going back. Currently I'm running the new years full f2fs version
[Nexus 7 Android Development] SkOrPn:
Hmm, ok it must be the kernel then, because that is the same setup I am using and it did not work for me. I was on both the Phatom kernel and M-Kernel, but your on LeanKernel.

I tested XenonHD for a day and did not like it at all, so going to flash back to New Years build here in the next few minutes. Thanks for the info :good:
[Nexus 7 Android Development] dareino:
I am running multirom with Freak/Phantom as my primary and Xenon/tegra 37.1 as my secondary with no issues. All-f2fs

D
[Nexus 7 Android Development] SkOrPn:
You didn't answer the question though. Can you run fstrim on your setup? What do you get when you try to? That is my ONLY issue, as I couldn't run fstrim without an error.
[Nexus 7 Android Development] :
Hey guys/girls

I would like you to know that I will not working on this ROM anymore( in the next time ).

This has multi able reasons :

1. I am trying to get this ROM booting again since 2 weeks without success (that frustrated me a lot )

2. I have to do a lot for school

3. I personally don't use this device anymore

I will start building again if I have more time and I have fun to build for this device again.

Please remember I do this project in my free time and for free. Please don't ask for ETA's otherwise I will close the thread.

Thanks for your support and all the great feedback :o
[Nexus 7 Android Development] SkOrPn:
Thank you for everything you have done to date for us. And thank you for giving me a reason to not flash as often as I used to do. Now finally I can just enjoy a great working fast ROM, instead of flashing constantly trying to find a great working ROM. Thank you for that...

Also, real life always comes first, so good luck with your schooling. Let me know if you ever need me to test another build for you. Thanks again man... :good:
[Nexus 7 Android Development] FormeriPhoney:
Hey guys. I'm trying to breath some life back into my son's 2012 Nexus 7.

Ran slim on several nexus devices in the past and loved it.

I'm not Interested or familiar in the F2FS build.

I just want the quickest and most stable version as he just users it to watch YouTube & sesame Street episodes.

Which version do you recommend?
[Nexus 7 Android Development] SkOrPn:
Umm, the EXT4 version I would recommend if you don't want the faster F2FS version. The ext4 version will give you a bit more system space too, which I think will help to prevent slow downs in the future (I have not tested that theory though).

Good luck
[Nexus 7 Android Development] dareino:
oh heh...acutally I thought the discussion was regarding which kernel was/wasnt booting up w/f2fs....but ya when I run the command, I also get a similar error message as u do...I read somewhere its the memory controller and running the fstrim command isnt needed....

d
[Nexus 7 Android Development] FormeriPhoney:
Just flashed it with the slim gapps. Up and running well as of now. I only use VLC player and YouTube so I don't put a strain on it
[Nexus 7 Android Development] ichigo_kurosaki:
Before you leave us though please wait for the next version of lollipop with the memory leak bug.:D of all the lollipop roms I tried yours is the fastest and the best.
[Nexus 7 Android Development] SkOrPn:
EDIT:

Never mind me... lol
[Nexus 7 Android Development] :
I will post another build but I don't know when I will do that ... Maybe this weekend maybe later... I think I will stop this devolpment for about 2 or 3 weeeks. Development is too much fun for me to stop that. :o
[Nexus 7 Android Development] SkOrPn:
Take your time but its not fun when development time is wasted on a device that won't boot. Lol

Appreciate keeping this device alive. I'll tell you this much. My son's 2012 Nexus 7 was on stock 5.0.2 and limping lol..

[Nexus 7 Android Development] x3dnd3x:
Sorry for the noob question. How I do know that I'm on f2fs? :confused:

I flashed using OTG and everything succeeded. I didn't want to go to LP yet so I flashed 4.4.4(v8.12) f2fs. Went to "About Tablet" but it doesn't say anything about f2fs. Rebooted back into recovery and check current system, it says f2fs. This means I'm now on f2fs? :confused:
[Nexus 7 Android Development] SkOrPn:
Just use Disk Info
[Nexus 7 Android Development] x3dnd3x:
Okay. I'm on f2fs. Thank you!
[Nexus 7 Android Development] x3dnd3x:
I'm wondering, would I still need the "special TWRP" recovery installed? :confused:

I'm not sure whether a special recovery is needed or the old TWRP recovery is still usable.
[Nexus 7 Android Development] SkOrPn:
2.8.4.1 should work best for you.

Sent from my Nexus 7
[Nexus 7 Android Development] x3dnd3x:
I'm on that version now. Haha. I guess I shall not touch anything further. Tried to boot into recovery just now and thankfully, no issues after.

Shall see what's the difference between f2fs and ext4. Grouper here is just to watch movies and play games OTG.
[Nexus 7 Android Development] JPHCCFC:
Had anyone has any success getting AOSP browser installed on this? My performance has degraded over time and trying to find alternative browser's to chrome which is slow. Also any recommendations to get this back to it's original performance... Starting to think a full wipe and reinstall...
[Nexus 7 Android Development] FrutasX:
Hello,

when goes to first boot ask me some password??? then says i have to reset and restart to the same thing!!! wtf??

Thanks
[Nexus 7 Android Development] Reiven89:

[Nexus 7 Android Development] khaytsus:
Obviously your filesystem does not match the rom you flashed.
[Nexus 7 Android Development] FrutasX:
OK. Thanks
[Nexus 7 Android Development] SkOrPn:
Just flash the same ROM and newer gapps over the top of it. Or just clear the cache maybe. Also, try Lightning browser and or Dolphin with Jetpack enhancement.

[Nexus 7 Android Development] brooker88:
So this rom works fine? Only thing missing is camera right? How much screen time are people getting without gaming?
[Nexus 7 Android Development] carlfinity:
More than fine, this ROM is great ! And yeah, camera is not working tho, but not a big deal for most users! :good:
[Nexus 7 Android Development] fantabrothe:
hi mate, since 5.02 factory image for tilapia is now released (, https://developers.google.com/android/nexus/images) there's any possibility for a proper f2fs release of your work? thx!
[Nexus 7 Android Development] :
There are two problems:

1. My ROM doesn't boot anymore and I don't find my error

2. I don't own this device so I can't test the ROM on it

Reason 2 is not the problem someone of you could do this but the first reason is very important or not ? ;)
[Nexus 7 Android Development] fantabrothe:
what a pity! i hope you'll have time to find the error, of course no problem to test and report if needed, bye!
[Nexus 7 Android Development] pjcanales:
Were the latest release at. Not sure if it was the new year one or not.
[Nexus 7 Android Development] SkOrPn:
Yeah its the New Years build.
[Nexus 7 Android Development] pjcanales:
Link to new years ROM please. Also does it include a new kernel or still mkernel?
[Nexus 7 Android Development] SkOrPn:
https://www.androidfilehost.com/?fid=95887005526786442

Its not using M-Kernel, but kernels can be flashed when ever you want a different kernel.
[Nexus 7 Android Development] Brock Samson:
First I want to say this ROM is really fast so far. I've only ran into one problem. I'm running 5.0.2 on f2fs and the only thing I'm having an issue with is I can't download anything. It always says download unsuccessful or download failed. I was wondering if it had something to do with the f2fs partition, but it shows that I have a little over 8gb available. I'm wondering if its something in the settings somewhere. Its probably something that's really simple and I'm over looking it, but any help would be great, thanks.

PS, I also can't send any file over Bluetooth to the N7, so it makes me think something is going on with the storage

Edit: just tried to take a screen shot and it said it couldn't save because there wasn't enough storage. I'm a bit new to the whole f2fs thing, but I have system, data, and cache, formatted to f2fs, is this right?
[Nexus 7 Android Development] SkOrPn:
I have never had a problem downloading on my device or this ROM so you might want to flash it one more time. Also try ADM with your downloads and see if your successful with it instead of the built in downloading feature.

Sent from my Nexus 7
[Nexus 7 Android Development] Brock Samson:
I flashed another f2fs ROM and it told me right away that I didn't have enough storage. Out of curiosity, what is internal storage supposed to be formatted as? I'm wondering if I accidentally changed that. I think tonight or tomorrow I'm going to go back to ext4 and see if that works, then start over from scratch.
[Nexus 7 Android Development] SkOrPn:
You don't need to format internal storage, only system, cache and data. If you find the time try going back to stock, then use TWRP to format /system, /cache & /data to f2fs (DO NOT use the wipe slider as that will also format your internal storage area and all your files). F2FS uses more space to do its magic, so maybe you have a lot of files stored on the device taking up too much space already? At any rate just go back to stock, then use twrp to "change" each partition mentioned to f2fs manually. Use either OTG to flash the rom or put the rom on the freshly wiped internal memory before leaving the stock rom. However, this can be time consuming though, so I ALWAYS use OTG to do tasks such as this. Good luck

EDIT: Never mind me, the TWRP Factory Wipe does NOT format your internal files, so all your music files etc will be safe.

If you like you can support me with donations ... My ssd is too small to build 2 sources at the same time. I would buy a bigger one but I need more money. So if you like you can donate via Paypal . It's not necessary and nobody has to donate

[Nexus 7 Android Development] FlatEric0074:
Thanks for your effort but rom isn't booting on an all-f2fs grouper. Stuck at Google logo. Will only boot after manual installation of m-Kernel. And then the system partition is formated with ext4, was before the Rom installation f2fs.... hmm... strange.
[Nexus 7 Android Development] :
Thanks for this report . Anybody has this issue too? I didn't test the f2fs version but if you have issues I will test it

edit

Fixed F2FS version
[Nexus 7 Android Development] :
For the Flo version you have to wait until slimLp is released . I got an error and I don't know what's wrong . I you would try an similar ROM you can download the slimkat of RobbieL811
[Nexus 7 Android Development] FlatEric0074:
Thanks, new version runs without any problems :) !

Hi Freak, I've tried flashing SlimKat with the instructions provided and I seem to be stuck at the SlimKat loading screen. I've wiped cache/dalvik etc, tried clean flashes twice with wugfresh's kit and also through TWRP.

Any help is appreciated!
[Nexus 7 Android Development] :
Which Version did you try
[Nexus 7 Android Development] Keydogg1:
Thanks for the quick reply mate! :)

I was trying the latest f2fs from 11th November. I was on stock lollipop so I flashed stock 4.4 first and made sure that worked before trying slimkat. I've never tried anything other than stock on this particular device, but flashed rooms on others in the past.

Thanks!
[Nexus 7 Android Development] :
Did you convert the filesystem to f2fs?

I think you don´t use the Fixed version

The lastet f2fs version is working perfectly I am running this version at the moment and i haven´t got any problems ( Don´t use grouper that much in the last time but i don´t noticed any error)
[Nexus 7 Android Development] Keydogg1:
I'm sure it's definitely my fault somewhere along the way I'm sure. I haven't converted to f2fs, I thought the rom package did this for me, oops!

---------- Post added at 03:22 PM ---------- Previous post was at 03:07 PM ----------

Going to flash back to stock then stick legokernel for F2FS on and try slimkat again :)

Thanks. I wonder if I accidentally formatted internal before. What is the stock format so I can check or correct it? I'm wondering if I changed it and now it won't write to it or something. I was messing with my phone, nexus 7, and a Asus transformer at the same time so its pretty possible that I may have rushed something.
[Nexus 7 Android Development] Tarney:
Feel like such a noob, I installed the full gapps x3 but can't see the play store or download the play services...pls help
[Nexus 7 Android Development] Brock Samson:
So I wiped my internal storage and made sure cache, data, and system were formatted to f2fs and reflashed. So far it seems like its working. I'm currently thinning out my backed up stuff to put back on my internal but so far so good. This ROM is super fast.
[Nexus 7 Android Development] BlueKnightedDragon:
Try fresh install then use minimal Gapps since playstore and play services may not have installed due to storage limitations with f2fs
[Nexus 7 Android Development] SkOrPn:
If you went with F2FS you can not use full gapps, you need minimal gapps (as small as possible), then install what you absolutely need from the play store. Do not install an app on this device that you do not use, this device just does not have enough ram for that when formatted to F2FS. EXT4 is better if you must have lots of software.
