OTG cable attached? If so, try removing it and see if it charges.
[Nexus 7 Original Development] :
I can't seem to get supersu v2.68 or v2.66 to install through recovery. I have all partitions set to f2fs. I may try turning off f2fs on the system partition to see if that gets it to work. Pretty sure it worked on the older version you released. Thanks for the rom btw.
[Nexus 7 Original Development] LordNerevar:
That is a possibility. For some reason, F2FS uses a lot more space than EXT4 and there may not be enough left for SuperSU on /system. When I changed /system to F2FS in TWRP, it said it was already using 122MB and there was nothing on it. So, I recommend leaving /system as EXT4 until I can find a way to turn F2FS overprovisioning down (assuming there is a way as the -o switch to mkfs doesn't seem to make much difference).
[Nexus 7 Original Development] TheRicolaa10:
Just flashed this ROM, after not using my N7 for months. Feels smooth. Should have done this earlier.
[Nexus 7 Original Development] :
I tried system partition with ext4 and data, cache on f2fs and supersu still wouldn't budge. I next flashed your rom, pico gapps and supersu v2.68 during a new install and everything worked like they should. So i don't know if there is a issue with the gapps you included but after flashing my own it works with all f2fs or any other partition setup i choose and supersu installs like it should. Hope this helps. All is fine now so far. Thanks for the reply and suggestions. Enjoying the rom.
[Nexus 7 Original Development] CCarson:
My dock seems to be charging, and playing audio, as it did before the update. For reference, I dirty-flashed over the older Nerevar ROM and kernel. Wiped cache and dalvik. System is ext4. I used TWRP 3.0.1.0.
[Nexus 7 Original Development] Paddy's:
Tilapia version ?

Hi LordNerevar , i wonder if you could make one version of this amazing rom also for tilapia, because i need 3g and i would like to have slimkat with security updates etc . For me it's ok even if you could make only one updated tilapia version and never update it anymore.

Sorry if bothered you and of course you developers are not required to do anything we ask. Thanks anyway
[Nexus 7 Original Development] blackdeath09:
Hello everyone!

I've been running this ROM on my Nexus 7 for the last couple of months becuase I feel it is the only one that is realtively fast on my device.

However, during the install of the last update I got an error while installing it on the 50-slim.sh script (something about the end point not supporting the operation). Even though TWRP said the operation failed, the ROM installed fine but the old kernel I had remained installed (so most likely the installation script broke thowards the end).

Lord Nerevar, may I ask, should I worry about the error (I tried a second time and still got it) and for the fact that some things from the update might have not been installed, or I should be fine?

[Nexus 7 Original Development] LordNerevar:
That error has been related to TWRP version in the past. Which version of TWRP are you using? I've had no problems with 2.8.7.0 and 3.0.1.0. I see 3.0.2.0 is out now but I haven't tried it yet.
[Nexus 7 Original Development] blackdeath09:
I am using 2.7.0.0 because in the past I had issues with newer versions (namely not being able to flash a separate kernel afterwards) and this version was recommended in multiple places. I'll try a newer version and let you know

Edit: I managed to install it succesfully using TWRP 3.0.1.0 but while I tried to install a 3rd party kernel it didn't installed correctly. So I am back on an earlier recovery (2.8.3.0) to flash the kernel. But the important part is that the ROM flashed correctly. Thank you very much for your support! :) Have a nice day!
[Nexus 7 Original Development] Ryuuga:
Help me out here a bit. Been trying to work on this for two days now.

I flashed TWRP 2.8.3.0> formatted data and cache to f2fs> flashed slimkat> flashed m-kernel a69

the first two steps work fine but when i get to flashing the kernel it either 1) gets stuck on SlimKat boot logo or 2) boots into the system with error "process com.google. etc has stopped" prompting repeatedly.

In my attempt to try to fix number 2), I now can't access TWRP recovery (stuck on TWRP logo bootloop) and am forced to reset system to a clean slate and start over for the third time :confused:

Edit: bootloader version 4.23, adb 1.0.32
[Nexus 7 Original Development] Promez:
just to know, are you going to update the security patches? :D
[Nexus 7 Original Development] blackdeath09:
I've had something simillar happening to me when I tried to flash a kernel that might have not supported F2FS or that was incompatible in a way (though MKernel a69 should be fine). The way I fixed it was returning to the stock factory image and then trying to re-do the whole process (just like you - I figured something corrupted the FS). I obviously lost everything on my tablet but it worked.

If I were you, I would try to flash the latest ROM version with the latest TWRP and then have it boot. After that you could try flashing the kernel with an older version of TWRP (I personally used succesfully 2.7.0.0 for the kernel flash, have yet to try 2.8.3.0). Also, try updating all partitions to F2FS. Even /system
[Nexus 7 Original Development] Ryuuga:
Thanks for your help.

I've currently manage to flash DC-kernel (daniel_hk) with TWRP 3.0.2-0. Figured i don't wanna keep banging my head into a wall with a69. Its been running smooth so far.

One thing I noticed today, is the volume on slimkat lower? I maxxed out the volume but still can barely hear a thing... (previously running AOSP MM which was way loud)
[Nexus 7 Original Development] blackdeath09:
No problem, I'm glad you are up and running now :)

Honestly, I feel the same but I thought it is normal behaviour from the tablet. However, I installed Viper4Android and the sound is a lot better now. I had a dream audio combo before my FS corruption (which I haven't been able to remember) but what I have now is also fine.
[Nexus 7 Original Development] Ryuuga:
Cool, I'll check that out. In the meantime maybe [MENTION=4398536]lordneverar[/MENTION] can address the volume issue in the future.

Keep up the awesome work! Loving this ROM more everyday for reviving my almost dead N7!

hello thanks for update rom slim.

[Nexus 7 Original Development] Reiven89:
Hope to see an updated version of this great rom with the latest security fixes.....thank you very much
[Nexus 7 Original Development] LordNerevar:
There's a little update available today. The biggest thing probably being inclusion of the April security patches. I've tested flashing SuperSU through recovery after a clean install and it has no issue (stable or beta version). You can also install it via play store if you enable the built-in super user first through development options. If you're installing a different kernel, make sure it supports the features you're using and let me know why you're flashing a different kernel (maybe I can include it). Oh, and let me know if sound/volume is any better with this release. There were a few minor tweak in that area.

Cheers!

Otg issue on latest build

Otg issue on latest build, after unmounting otg, as soon as i remove it, it hangs and restarts after few seconds.... I have clean installed, any solutions? In older build it never happend
[Nexus 7 Original Development] LordNerevar:
I've confirmed this and am looking into it. You'll probably want to revert to March build for now.
[Nexus 7 Original Development] bilakos10:
I believe that the latest build is a bit laggy while animations take place (e.g when opening the app drawer)

Is that a thing for any other user?
[Nexus 7 Original Development] LordNerevar:
I've uploaded a new boot.img to address the OTG issue. It may address other issues as well as I've reverted the kernel to SlimLP from previous builds. This is provided as a flashable which can be installed after installing the April build. There should be no need for a clean install if you're already running the April build. This was confirmed to work with TWRP-3.0.2.

[Nexus 7 Original Development] MALditoNica:
I installed this ROM a month ago, as a last resort to keep using my old Nexus 7. I wiped everything, turned everything to f2fs and installed. But then, nothing, the lag was even worst. I had to wait SECONDS for a tap to execute. I've been traveling these past weeks, so I haven't used it that much, but every time I did, the same painful experience.

Yesterday I came into this forum to search for a solution but no one else seemed to have my experience. However, on a post, I found someone talking about using fstrim. Right away I downloaded an app, ran the trimming process and NOW I see how fast this ROM really is.

So, if you feel your Nexus 7 is slow as hell after installing this ROM, try the trimming thing, it might be what you need
[Nexus 7 Original Development] Reiven89:
This rom, on full f2fs partitions + fstrim is the smoothest rom ever made for our tablet !

Really hope this will be always supported by updating to the latest security patches.....thank you very much for this, just resurrected my n7 after laggy marshmallow
[Nexus 7 Original Development] LordNerevar:
There's a minor update to the ROM out today. You should notice a little better throughput on WIFI due to the kernel changes. I've turned off the discard mount option for a slight speed improvement but you'll need to use fstrim occasionally. Finally, I've updated to the May 2016 patch level. There's no need for a clean install.

Cheers!
[Nexus 7 Original Development] LordNerevar:
I've just created a tilapia build. I don't have that device to test so I have no idea if it works but the device tree seems easy enough to get this going. If you want to give it a try, be sure to know how to backup/restore your current ROM first. Please let us know if it works! Thanks!

Hi LordNerevar, today i read accidentally your post and i tried this tilapia version on my all F2Fs tilapia .After i ran fstrim one time,3g connection and everything worked great, even with dirty flash, because i already had official slimkat f2fs and i wiped only system,dalvik and cache before flashing the rom.

Moreover, i found here on xda a fixed version of xposed that works with security updated slimkat (it's on "Xposed for android 4.4.4 not working anymore + FIX" xda thread) .

I tested also parrotmod(i flashed supersu before) , and it seems to make the device even faster .

So ,based on my experience you can also put tilapia on the title of this thread and thank you very much for your amazing work .Have a nice day .

June Update

Very minor update posted today for June security fixes from Google. I've put Grouper and Tilapia on the second post for easy downloading.

Cheers!
[Nexus 7 Original Development] zerbey:
Couple of issues with the 06/30 update, not sure if this affects everyone but passing along my fixes:

1. Google Apps kept crashing. Go to Settings->Apps->All, from the menu "Reset app preferences". Also wipe dalvik for good measure.

2. SuperSU binary update failure. Manually flash the zip version, reinstall apk via Play Store and, finally update binary again when prompted.

Hope this is useful to others.
[Nexus 7 Original Development] Paddy's:
Thanks again LordNerevar, i installed the june update on my tilapia and it is very good. The default email app still crashes when i click on settings after i set up an hotmail account, but i removed it.

Is there any benefit,other than overclock, installing dc kernel ? I don't want overclock because i prefer low battery consumption, so is the stock kernel the best choice for me ? thanks
[Nexus 7 Original Development] LordNerevar:
I'm not sure why the email app is crashing. I tracked down my hotmail password from years back and I'm not seeing an issue after setting it up and going to settings. If you want, post a bugreport and I'll see if it's something I can fix.

I bricked my phone..

I bricked my *Nexus 7 tab

Device - Nexus 7 2012 WIFI , boot unlocked, CM 10.1, rooted.

So this time, I downloaded the grouper rom, saved it in the phone, went to twrp recovery (phone boot unlocked, rooted), and wiped dalvik cache, cache, data, system AND (face palm) internal sd. I then proceeded to format cache and data to f2fs.

All good so far.

I selected reboot to bootloader (thinking I can just fastboot flash the ROM ). The device powered on to the image with an android and the START in green so i could select to go to fastboot. Volume keys did not work anymore. So now i just pressed the power button again.

And ever since am stuck with the Google logo. With an unlocked Lock icon.

I can not go to recovery nor fast boot. Power off + vol down, PO + vol Up, PO + vol up + vol down,pressing the keys for 20 seconds or more, none of them took me to recovery or fastboot.

PC and mac both detect the device in ADB. But " adb devices shows the device number and "unauthorized". So no command works on adb either.

So I can't fathom what went wrong. How do I bring back the device from here? Please help. :fingers-crossed:

[I am fairly good at installing ROMs and have done this several times for the past 5 years. ]
[Nexus 7 Original Development] LordNerevar:
I've found that my nexus 7 doesn't reboot when doing the three fingered salute until after you release all three buttons. When I get in jam from a bad kernel tweak and the like, I hold all three buttons for 15 seconds and then release. As soon as the screen flashes (can take a few seconds), press and hold power and vol-down buttons to get to the bootloader. Hope that helps. If not, you might want to post in troubleshooting.

Something happened with my Nexus 7 today. I tried to run an app and the entire device seemed to lock up. I didn't wait very long to see if it would come back, I just rebooted. When it came back up the launcher was cleared. The only apps in the app drawer are the stock Slimkat ones. My stuff seems to still be on the device because roughly 9G of space is used. The app manager shows no downloaded apps installed. Help?

Quick question: is anyone using the multi-user feature with this ROM?

I found that I can only set lockscreen settings for the primary user but not the additional ones. Is this an issue with this ROM or it's a general SlimKat issue? or maybe it's me?
[Nexus 7 Original Development] fgimenezm:
well, I'll answer my own question.

I found a workaround using the "Manual Intent Shortcut" widget from play store and these details:

Action=android.intent.action.MAIN

Package=com.android.settings

FQN=com.android.settings.ChooseLockGeneric

I added a shortcut to that intent in my secondary user's main screen and now they can use it to set their lock code as they feel like it :)
[Nexus 7 Original Development] revmra:
I hate to quote myself, but does anybody else have any suggestions at all? I'm at a loss here. At this point, I don't know whether to just wipe and start over or reinstall the stock firmware.
[Nexus 7 Original Development] thoiloidainhan:
Wipe and start over. Did u turn off fsync? With fsync off data could be corrupted when power cut off suddenly
[Nexus 7 Original Development] revmra:
I ended up doing that very thing. Unfortunately I found that wiping through the Backup & Reset menu doesn't actually clear the device storage. All my downloads were still there as was all the many gigs of Bard's Tale data.

Honesty not sure what fsync is, much less how to disable it.
[Nexus 7 Original Development] thoiloidainhan:
Its a kernel variable. Turn off for better io performance at the risk of corrupted data. Don't actually remember if slimkat had the performance app for kernel controlling baked in or not. If it is u can find it in setting. Check if it is turned off by default

Hi,

Thanks for the ROM, now my N7 feels relatively fast again.

However, where can I set the pattern unlock for the lockscreen? Is it really missing in this build, or why can't I find it in the settings.

It used to be in the security settings, but now there is nothing except the encryption option.

[IMG="security"]http://i.imgur.com/4edku7s.png[/IMG]
[Nexus 7 Original Development] xeno91:
Find it in settings - interface - lockscreen
[Nexus 7 Original Development] proguru:
Thanks, There it is indeed :good:

I don't understand why I didn't find it no matter how much I browsed through the settings.

This is a great rom, definitely it is fast, but also all the small tweaks and additional functions makes it much better than the stock Android on Nexus 7.

I installed this rom together with ParrotMod (http://xdaforums.com/nexus-7/orig-development/parrotmod-speed-2012-nexus-7-emmc-fix-t3300416), that may also have some contribution to the fast usability of the device.
[Nexus 7 Original Development] fgimenezm:
If you use the multi-user feature you'll soon notice that settings menu is only present for the main user.

I posted how to create a shortcut to the lockscreen settings for the secondary users a few posts ago in this thread :)

Can i format cache and data with twrp without using a pc or usb pen?!?

It will erase internal storage?

Anyone has a link with procedure to share?
