I'm now running SlimLP with Phantom r2 kernel (flashed straight over my existing SlimLP (m-kernel) setup). First impressions are good :) At last, my logcats are no longer swamped by busybox SIGPIPEs (as was the case with m-kernel).

Incidentally, I've finally (accidentally) discovered the reason for the extremely heavy disk I/O, which has plagued my N7 for many months: Gmail and Inbox sync. This behaviour is (sadly) independent of rom, kernel and filesystem, so I'm not sure I can do much about this :(
[Nexus 7 Android Development] khaytsus:
I don't use GMail or Inbox. But always could be other similar things. What did you use to determine those were the specific apps causing heavy IO?
[Nexus 7 Android Development] ogilviea:
Nothing (unfortunately, I/O accounting isn't enabled on m-kernel or Phantom) - hence my "accidentally" comment :) I was simply observing the system I/O performance using System Monitor, and spotted the pattern that the massive lags occurred when Gmail and Inbox were syncing. Then I tried manual syncs and reproduced the I/O behaviour every time.

Does otg work on this Rom?
[Nexus 7 Android Development] QBall45:
It sure seems to work for.
[Nexus 7 Android Development] pjcanales:
Where did u buy your cable bought one off eBay it doesn't seem to work on my nexus 7 but works on my ATT hct one xl
[Nexus 7 Android Development] SkOrPn:
OTG is nothing more then a short between two of the USB pins. What you are saying suggests your Nexus 7 is faulty somehow, not the cable. When you connect it to your HTC One and it goes into OTG mode, then you just proven that the cable is obviously good. It is probably the Nexus 7 that has an issue or it has a bad or bent pin or a ROM/Kernel that is not supporting OTG.

EDIT: Do this as a test. Launch into TWRP Recovery and enable MTP. Then connect your OTG cable and flash drive and use the file manager to see if you can navigate and see files on your flash drive. If so, the OTG cable is working fine and so is your Nexus 7. You have a problem somewhere else in that case.
[Nexus 7 Android Development] pjcanales:
I tired what you suggested but it won't let me mount it. My brother had a spare cable and it work great but I lost it so had to buy this one which appear not all cable works with every device for somebreason. It inscribed infinity on one side of it. May I ask were you purchase yours since your seem to be working correct?
[Nexus 7 Android Development] QBall45:
I bought mine on Amazon.
[Nexus 7 Android Development] SkOrPn:
I manufactured my own as I do with all simply designed cables such as this.

ALL OTG cables have pin #4 soldered to pin #5 with a tiny small wire, at least all the ones you will buy on the internet. I purchased my bare DIY connectors from ebay in bulk every year, and the cables at Monoprice usually a hundred at a time. That is what I do for a living... Build USB Cables.

Here is a OTG Guide at XDA. You can also find dozens of guides on the internet and several on YouTube. Its easy Pin4 to Pin5 on the micro side and your done.

Use PA gapps. The one in the op doesn't work as full. Or you could use the slim version.

Wipe, flash ROM and then slim gapps.

I've tried that, same thing happened :(

Hey, I'm thinking about getting a nexus 7 4g 2012. I've been wanting a tablet for awhile. I've been looking at the galaxy tabs 3 and 4 but development is not going any were that I've seen. Would the nexus be a good choice?

Also in the nexus 7 forums, is the roms for nexus 4g 2012, or the nexus 7 2013 or will the roms work on either. Sorry if I posted in the wrong place. Thank you
[Nexus 7 Android Development] khaytsus:
OTA; ie: USB Host Mode. Works just fine. I'm using a Realtek SDR with my N7.

If you mean something specific, like mounting a flash drive, maybe. If it doesn't, use StickMount.

Oxydo revamped is fantastic with this rom
[Nexus 7 Android Development] JPHCCFC:
What benefits are there to using the oxydo kernel?
[Nexus 7 Android Development] trvbone:
I'm not sure what the exact culprit is but there's been discussion about ramdisk issues or something's not using the memory properly with this rom when it has the m kernel. For example I would be using my tablet and multitasking is almost impossible because I can't switch from one to another. Then it would just kind of hang or freeze up. I'm not having the same problems with this other kernel.
[Nexus 7 Android Development] mariocaraujo:
I installed phantom kernel r2 with this ROM(F2FS) and the performance is amazing, the kernel improved it a lot.
[Nexus 7 Android Development] Zokinet:
Thanks for the rom!
[Nexus 7 Android Development] carlfinity:
Likewise here, that kernel works wonders on build 0.91 :good:

"Memory leak bug"

it's not issue with this rom. it's issue with Lollipop in general but called "memory leak" bug wherein RAM consumption is higher than usual esp when we run ram intensive apps like games. it will be fixed in next update (5.0.2 or 5.1) and has been acknowledged by google.

---------- Post added at 05:44 PM ---------- Previous post was at 05:36 PM ----------

that is because the Phantom Kernel is the only full lollipop-based cutom kernel. the MKernel that came with this ROM is onlypart-lollipop. it's still kitkat based. so i have to assume the lags here andthere were caused by slight compatibility issues.:) even Metalice acknowledges this problem and has said he will released a full lollipop MKernel. for the meantime let's enjoy this rom with Phantom Kernel.:D and we are still having a bug with Lollipop in general..the "memory leak" bug that google will fix in next update (5.0.3 or 5.1?)
[Nexus 7 Android Development] uxu:
just one question, the 0.91 Version of this ROM is also in F2FS Format, right?
[Nexus 7 Android Development] carlfinity:
Yes there is an F2FS version for this rom. Just look for the correct download link. Cheers!

Anyone know if it's easy to put /system back on ext4? I want a minimum of 25% free space but not sure what the best route to go would be. Either going back to ext4 or trying to remove more system apps.

I just want to experiment to see if ext4 on system using this ROM is still as fast as F2FS. I already formatted it to ext4 yesterday but after flashing the ROM it went back to F2FS on its own, no doubt because I forgot to edit the install script.

Happy New Year from me too !!!

Am working on a cool and handy feature which needs some more work .

Think I will release it on the weekend or next week
[Nexus 7 Android Development] sTl2yk3l2:
Just wanted to say I'm using the lean kernel on the f2fs version and everything is working fine now. Way better then the mkernal. The mkernal version on my device was really unstable. Overclock values still won't stick. As soon as the screen goes off back to 1.3. But am finally enjoying 5.02 and this Rom.
[Nexus 7 Android Development] SkOrPn:
The new version of this ROM will be using a different kernel, plus M-Kernel overclocks stick when using something else besides Trickster. I get them to stick with no problem when I use SetCPU from the play store, but Trickster does not stick for me. M-kernel works perfectly for me on this ROM, and so does Phantom Kernel...

When the camera will be fixed?

Thank you very much for your work :)
[Nexus 7 Android Development] tcat007:
What's to fix? Google Camera/Playstore works file.
[Nexus 7 Android Development] SkOrPn:
Which Google camera exactly? Link please because I tried everyone in the Play Store and not one works...
[Nexus 7 Android Development] tcat007:
https://play.google.com/store/apps/details?id=com.google.android.GoogleCamera
[Nexus 7 Android Development] SkOrPn:
Thats what I thought. It does NOT work on this ROM.

OK, freak_97 and I want to know your exact setup please. We both can't get any of the Google Cameras to work, not the old one or the new Dec 17th one you claim is working. So, please instead of just saying it works for you, please tell us some specs. Are you using this ROM? if so which exact version build? Are you using Gapps, if so exactly what version? If your using F2FS, exactly which partitions? What recovery do you have?

freak_97 spent some many hours today on the camera and its not working for him no matter what he tries... It does NOT work for me either and I tried half a dozen different cameras today... Since you got this working please share how?
[Nexus 7 Android Development] tcat007:
So sorry, flashing too many ROMs lately. I have Slim on my Nexus 7 and don't use a camera. Thought I was on the Optipop thread, camera works fine on Nexus 5.
[Nexus 7 Android Development] SkOrPn:
OK, thanks for the information. That is what I thought... Back to square one I guess.... :( And to think I almost flashed Banks just for the heck of it and in the hopes the camera would start working, lol...
[Nexus 7 Android Development] papajonpizza:
I think it's the source that has the broken camera. I tried Rasta Lollipop 5.02 and Camera also doesn't work there. The bshiznit Lollipop AOSP 5.01 has a working camera, but there is a noticeable difference in performance vs Freak-SlimLp, so I went back to Freak-SlimLp albeit no camera.
[Nexus 7 Android Development] SkOrPn:
OK, thanks for the info, I will make sure freak knows about it. I'm not interested in a camera for myself (I already have real webcams and a real digital camera), I just want it for everyone that keeps asking for it and to help freak_97 figure out what is wrong. If at any time I need a good camera on a tablet I will pick up the 2013 N7 or the new N9, or maybe just maybe the Samsung Galaxy Tab S. Lol
[Nexus 7 Android Development] carlfinity:
I don't think there is the need to repeatedly bring up the camera issue as it was mentioned by the dev in the previous threads that its not working as of the current builds. The reason behind this is yet unclear.
[Nexus 7 Android Development] webdroidmt:
Camera works fine on Rasta LP, it's been working right from the first build. Matter of fact, just snapped a pic on it. :) Google Camera comes up as non-compatible in Play Store, I'm guessing due to the fact that grouper/tilapia lacks a rear camera. I haven't tried sideloading it to see if it will work, because I'm satisified with the gazillion camera choices that will work.

AFAIK, this Slim rom is the only grouper rom that has a non-working camera. Hopefully, the Slim team will figure it out down the road.

[Nexus 7 Android Development] tomskra:
It is not about good camera. I have never use the camera app, but in this ROM you can't use video calls in hangouts or Skype. I think, this is the problem for most users.

Low memory killer **bug report***

Bug report...

Two key files controlling the behaviour of Android's LowMemoryKiller:

/sys/module/lowmemorykiller/parameters/adj
/sys/module/lowmemorykiller/parameters/minfree

have permissions '220' (-w--w----). Having these files non-readable is probably a bad idea!

It's probably too optimistic to hope that fixing this problem will help to remedy the performance issues with grouper, but who knows, every little helps. At the very least, fixing this problem will allow everyone to experiment with minfree values.

Coming from original rom and want to install this one.

Rooted, unlocked, installed rom and gapps. I see the bootscreen of this slimrom, but it doesn,t boot further. Keep seeing the flickering bootscreen with logo.

What am i doing wrong here? Missing something? Which gapps version do you advise?

I've had this happen to me before when I removed the stock keyboard and didnt have a second one to set as a new default one. Back button stop working all together until I installed a new keyboard.

Do you use the right version? If you came from stock you have to use the ext4 version.

I personally use the latest beta gapps but you can also use stable ones

Thanks man [emoji4] ... That was the mistake I made

[Nexus 7 Android Development] SkOrPn:
Rebooting recovery and flashing again might have fixed that, but dont worry about it now, the build is broken. He will try and fix it tomorrow.

Wifi has been confirmed broken, so the build has been removed guys. Man this thing flies though, fastest build to date... And yes it installed just fine for me and booted just perfectly as usual...
[Nexus 7 Android Development] ichigo_kurosaki:
i agree. this build is the fastest and snappiest lollipoprom..even faster thanstock.
[Nexus 7 Android Development] SkOrPn:
I actually asked him today in Hangouts what the heck was he doing to make it fly so fast. Its like he is putting new hardware updates into this ROM. lol

I cant wait for a fixed build that is this fast... He still has 3 days before he has to go back to School... ;)

0.92 was pulled so surely he means its working on 0.91, which we all know already lol.... Yet more example of that "users not paying attention" that bugs me... I guess I better go back to 0.91 before I go to bed and forget about it. Would suck if I wake up at 5 or 6am and have no news to read, lol.

Tomorrow I will ask freak to let me test it before he puts it up...

[Nexus 7 Android Development] ichigo_kurosaki:
[MENTION=5373714]freak_97[/MENTION]

my issue was with the 0.92 build. updater script or binary something. anyways, here's the screenshot of mine.
[Nexus 7 Android Development] secret.animal:
Use PA gapps, or anything but the full gapps. Full is not optimized for lollipop. I think it runs out of room even though it says it installed everything.

PA gapps are set up more for the tablet and their are many variations you can choose from.

But you have to wipe and start over. Flash ROM and then different Gapps.
[Nexus 7 Android Development] bobby8921:
I can't install PA Gapps Mini because of insuficient space on /system.

After the install of the rom, I have 260 MB free and 388 MB used.

Is it normal ?
[Nexus 7 Android Development] uxu:
It's normal, system partition is about 650 MB. Try PA Gapps Micro, that worked for me.
[Nexus 7 Android Development] bobby8921:
Finally made it.

Thanks for the help
[Nexus 7 Android Development] :
I decide to start from scratch ... I wiped my source and downloading now the source again.

I have to setup my build enviroment first( takes me about a day or two) before I can build again.

If you want to flash something new you can try this Build. It´s only f2fs compatible and I made it at the first of this year.
[Nexus 7 Android Development] pjcanales:

[Nexus 7 Android Development] gerardo87:
May I ask you if you have a changelog about this? If not then thanks anyway for your awesome work [emoji16]
[Nexus 7 Android Development] SkOrPn:
Changelog:

1. It is slightly faster.

2. It contains a new Kernel.

3. It has the Darker Settings UI.

4. Still based on the previous SlimLP alpha.0.91 released on Dec 20th (Slim-grouper-5.0.2.alpha.0.91-UNOFFICIAL-20141220-1511.zip)

Other then that, this was only a "test build" nothing more, and since I have been running it flawlessly since Jan 1st he decided to give ya guys it until his next official one was ready (for the flash-a-holics), which as he said may take several more days as he starts over from scratch.

So, just enjoy it, it is the best one I have flashed so far, but it is NOT one of his official release builds, its just a "test a new kernel for me build" and is based on his last 0.91 ROM as stated above.

As usual flash it at your own risk and please report any bugs in this thread.

If interested here is the info for checking integrity:

HappyNewYears version is really nice, thanks to Freak and Skorpn! I like the dark settings interface, and it's all quite smooth.
[Nexus 7 Android Development] gerardo87:
To update the Rom I must format system (and re-flash gapps) every time or is just an advice?
[Nexus 7 Android Development] treesurf:
I wiped system, cache, and dalvik and then flashed the ROM, PA Micro gapps, and SuperSU (probably not necessary). The ROM booted fine and all of my system settings were preserved, I didn't have to change anything. Very easy.

If you want to try a dirty flash, then give it a shot. If you have problems then you follow my procedure to flash again and you should be OK. No harm in trying either way.

Of course, always do a backup first. ;)
[Nexus 7 Android Development] gerardo87:
Yes I do the same and all my settings for system app are preserved too [emoji16] the only think is that I need to reflash supersu by recovery to have device rooted (but that is not a problem). Thanks again for this awesome Rom (really smooth and responsive like never I've seen on other roms)

Dirty flashing works fine
[Nexus 7 Android Development] ichigo_kurosaki:
sorry for quoting your whole post. bit too lazy to edit.:D anyway, is this happynewyear version ext4 or f2fs? and can i dirty flash this over my previous build (0.91)?
[Nexus 7 Android Development] amangupta53:
Looks like it's only f2fs for now. And you can dirty flash it if you had the f2fs version installed.
[Nexus 7 Android Development] SkOrPn:
Yeah it's only the F2FS version, sorry. Dirty flashing should go smoothly if your already on 0.91 since that is what it is based on.

I only clean flash when Android version number changes or I change to a different ROM.

The Goal with freak starting from scratch is because he thinks it will solve the camera issue. So if all goes well the next version just might have a working camera. Everyone who needs camera and loves this ROM please cross your fingers lol.
