Not working yet but I assume that [MENTION=5373714]freak_97[/MENTION] has higher priority issues to address.

I hope the camera fix comes in due coarse :o

***************************************************************************************************

Just flashed to new ROM and GAPPS mini package and so far it feels like a new tablet!

As recommended in previous posts, I did the following:

Wiped the tablet clean

Reformatted \system back to EXT4 (Was f2fs)

Flashed Slim-grouper-5.0.2.alpha.1.0-UNOFFICIAL-20150226-1601.zip

Flashed Slim_mini_gapps.BETA.5.0.x.build.0.x-20150226.zip

Signed into Google and let Google restore apps and data

Using TitaniumBackup, restored only app and data that have been downloaded from Google Play

Set "Transition animation scale" and "Animator duration scale" to .25x in the Developer options section.

99% of the apps worked first up. The only piece of data not restored by TitaniumBackup was the Viber data folder which contains the sent and received media files. In my case, that was 145MB. Need to make sure you back up this folder manually.

Now the only question remains is whether to replace the existing leanKernel with Phantom R2 or M-Kernel a74.

Over the next couple of weeks should tell whether the tablet maintains it great performance.

Overall, I am very happy with the result and wish to thank [MENTION=5373714]freak_97[/MENTION] for all his great work.

:good::good::good::good::good:
[Nexus 7 Android Development] techlifeweb:
Did pretty much the same thing except restored everything from TitaniumBackup. Getting some odd performance (just had to reboot because it basically locked up). This could be an app I have. Not sure yet, just reporting this for reference. I think I am going to wipe the system again then let Google reinstall everything.

I have been having problems with loading Plants vs Zombies 2 on Grouper, is anyone able to successffuly play this game on this ROM?
[Nexus 7 Android Development] pellajl:
Been using the tablet for a few hours now.

It seems that the tablet performs very well if you don't use any browser applications.

As soon as you use Chrome, read an online news paper through Wiki Encyclopaedia or open a http link within Facebook where Facebook now has its own browser capabilities, the tablet grinds to a halt.

I have received a few messages saying either Chrome, Wiki Encyclopaedia or System UI not responding and this is the same experience I had with the stock Lollipop and the previous version of this ROM.

There must be something fundamentally wrong in one of Lollipops inner modules which causes the Android system to stop.

Someone with more knowledge about what modules a browser app uses may be able to shed more light on the subject.

Update: I have just un-ticked the "Allow sites to run JavaScript" option in Chrome and the performance difference is spectacular. This seems to point to the Android Java engine being crap.

Does anyone know if another developer as optimised the Android Jave engine?
[Nexus 7 Android Development] Hai96:
yup, experiencing the same...but when you download these gapps there are only ~70mb.

but i have a problem with flashing gapps, everytime i flash gapps the recovery rebootsand my chache partition is back on ext4... iam on data/chache f2fs
[Nexus 7 Android Development] pellajl:
[MENTION=5174950]Hai96[/MENTION] - I had a similar where loading the ROM forced /system partition to unmount and the ROM would load. It was essentially a soft brick.

After a lot of playing around without success, I decided to bring the tablet back to stock using the WugFresh tool.

After loading the stock ROM, installing recovery and root files again, I was able to go through the SlimLp load process without any issue.

I hope that helps.

Chrome kills this tablet. I removed it and installed atlas browser this ROM is super fast now.
[Nexus 7 Android Development] :
My Own Gapps

Gapps have only the Playservices and the Playstore inlude.

I personally think everbody should be able to use the google apps he or she uses/needs.

With this minimalistic Gapps you can download the google apps you use via the playstore and you don´t have to install/flash apps you never use.

With my own Gapps I also avoid problems with people you can´t read or didn´t heart of this funktion called "search funktion" who have problems if they using normal Gapps.

Feel free to post Google apps you miss... I will update my Gapps every week and will realease them everytime I post a new build.

I try to update this Rom every Week about the same time as the offical Slim weekly

otg charging

Hi all

İt seems that this ROM with lean kernel does not support otg charging. I tried today with my car setup and an otg y cable, USB devices worked well but the tablet didnt charged.
[Nexus 7 Android Development] pellajl:
Yes I here what you are saying.....

Chrome has one feature which I find very useful - Chrome to Phone. For the moment, I have disabled javascript and Chrome performs well.

I tried Atlas but I could find a way of importing bookmarks. If I could find that function, I would have stuck with it.
[Nexus 7 Android Development] SkOrPn:
Chrome and Lightning Browser for me. Chrome runs great on this rom. The only thing that slows down Chrome are adblockers or a large hosts file. ABP however lets Chrome stay plenty fast.
[Nexus 7 Android Development] pellajl:
Just installed Dolphin browser. It performs very well and with an addin, syncs all the Chrome bookmarks on my Windows desktop.

Happy so far ?
[Nexus 7 Android Development] SkOrPn:
What did you do to make dolphin run good without any lag? I can't get it to keep up with my finger swipes. It takes several seconds for dolphin to register my touches.

Sent from my Nexus 7
[Nexus 7 Android Development] pellajl:
I must admit after about half an hour of using Dolphin, it did start to get a little laggy. Nowhere near as bad as Chrome. It seems to be worse after the tablet wakes up from a deep sleep.

I haven't noticed delays in finger swipes (yet - trying to be optimistic).

I will keep playing around with it and see what happens.
[Nexus 7 Android Development] techlifeweb:
Keeping Chrome but taking a different approach just to test.

* Leave javascript enabled

* Go to Settings -> Privacy and uncheck ALL boxes.

All this prefetching is supposed to speed up browsing but I think the CPU on this device can't handle it. Just a theory.

Browsing does seem faster but I haven't done extensive testing.
[Nexus 7 Android Development] ~wolverine~:
This is one of the smartest things anyone has every done. It's just enough to get in the Playstore and get whatever a person needs/wants. Thanks :good:
[Nexus 7 Android Development] Tibothika:
hello to the Community,

I come to you for a problem with the navigation bar.

In portrait mode, the 3 buttons on the navigation bar don't work.

I reinstalled the stock factory image 5.0.2 by fastboot and the buttons work very well. But as soon as I install the rom Freak_97 portrait mode keys stopped working.

I wonder if it don't come from gapps ... I tried with those recently Freak_97 upload and with the mini and normal gapps of slimroms and still the same problem...

I do not know what to do .... I'll try anyway with full gapps!

Thank you for your help.

In fact, your rom Freak_97 is wonderful ...

PS: It is normal if there are mistakes, I'm French ;)
[Nexus 7 Android Development] SkOrPn:
Hi, and welcome to the community.

What three buttons are you talking about?

---------- Post added at 11:15 AM ---------- Previous post was at 10:22 AM ----------

Chrome is very fast here, almost the fastest browser of them all on my N7. The only browser I have found faster is Lightning, and it just barely beats Chrome. Dolphin used to be my go to browser but it no longer registers screen touches instantly, so it lags when scrolling really bad. This device just does not have a processor strong enough to browse the Internet quickly, lol.

Have you tried using the flags in chrome to change settings so that it runs faster?

Try this in Chrome

In the address bar, type chrome://flags/#max-tiles-for-interest-area then tap the Enter key

Tap the drop-down for Maximum tiles for interest area, and tap 512

Tap the Relaunch Now button that appears at the bottom of the screen

Also try this tweak.. In the address bar, type chrome://flags/#enable-new-ntp, and tap the Enter key. Restart Chrome and report back. You can find these tips all over the internet, but my Chrome already runs good enough so I have not tried them yet.
[Nexus 7 Android Development] IFLPI:
Yep, I think this matter a lot, as I noticed we have very little /system partition free space (litterally nothing!) So I used Root Explorer and mounted system/app as RW and deleted hangouts, gmail,gallery, and more giving about 60MB free space vs 600KB (as some apps showed before. I used normal gapps)

Will flash the newest version to see what more improved..

Q: after setting CPU min/max to 300-1600 MHz, the values are quickly restored to original. How to fix that?
[Nexus 7 Android Development] SkOrPn:
I think try the freq lock feature. I also like 300-1600, but this new rom does not support 1600 mhz. Did you change the kernel to something else? The latest ROM only supports 1500, which is still OK imo.

Also, try the freak micro gapps, and then only install what you really need. I have 44% free space now and the device is just smoooooooooth as can be.
[Nexus 7 Android Development] IFLPI:
Ok, I'll try tomorrow the new rom. Im using the original kernel, maybe that is causing it. What kernel is worth trying?

Also when it comes to the browser I find Opera very nice lately, so I recommend the Opera
[Nexus 7 Android Development] bodega1968:
tried and tested...wonderful, sweet and will wait...

yo freak_97,

great work on the slimLP! i immediately set myself to installing it on my Nexus 7 all-f2fs (Grouper) and saw the dramatic different of LP. I only had to sideload an explorer program (*Perhaps, you could include a simple lighweight one within mini-gapps) so i could access the APK files in a folder in my internal storage, and begin voraciously installing my usual applications. So i had to use MyPhoneExplorer (*http://www.fjsoft.at/ : Great utility if you manage to get the RIGHT driver for your device!) to sideload rootexplorer. As a whole the workings of the system was digitally seamless!

there are some interesting surprises though (The absence of the camera functionality isn't really important to me, sides Nexus 7 (Grouper) only has a front camera). The more notable things pertain to compatibility issues. For example, Mantano Ebook Reader doesn't seem compatible with LP, and also Moonreader. These are, for me, VERY important utilities.

I have crossed over some sites that are now listing programs that are 'compatible' with LP (https://pateo.wordpress.com/). I only hope that my 'old' but very important utilities don't get bumped off by LP. So after a few attempts of not getting these utilities to install (even older versions) i simply reverted back to my original SlimKat. I may have to wait for a more stable and 'apk friendly and embracing' LP OS before i finally decide to shift. I wonder if this is the same experience for Stock LP in other devices.

In any case, it was fun tinkering with the LP environment. Very smooth, slick and sexy! Perhaps, the android virtual layer is no longer an issue with LP, but if it holds some compatibility nightmares, i guess no problem with sticking to KKat for a while.

Congratulations and thanks for the sweet test-taste of LP.

Some feedback on ROM performance

I have notice the latest release of the ROM drains the battery fairly quickly.

Even if I have the changing cable attached, the battery reduces steadily. The Battery status in the settings section doesn't reveal any rogue app. Also it took quite along time to fully charge the tablet.

This had me thinking about the kernel. This version of the ROM has the Lean kernel. I decided to replace it with M-Kernel a74 and have noticed that now battery levels actually increase when using the tablet with the charging cable attached.

The two worst performing apps on the tablet is Google Maps and Chrome. Chrome is still an issue despite implementing the suggested tweeks in earlier posts.
[Nexus 7 Android Development] brandub:
So I finally had time to try this, I wiped everything (but bootloader), made cache and data partitions f2fs using the latest twrp, flashed Freak-LP, Freak Gapps then supersu. Rebooted and stuck at slim boot logo. 10 minutes later I rebooted the device - cant get into recovery (boot failed message appears).

I tried flashing stock factory images (I can wipe all partitions but cannot install, after fastboot flash recovery recovery.img it says "writing 'userdata'...

FAILED (remote: (FileWriteFailed))"

tried google factory script, again it wiped all partitions but wont install. Im guessing those 2 partitions are still F2FS, so I tried "fastboot format ext4 recovery -u" - and any other partition - makes the tablet freeze and windows force closes fastboot.exe.

also tried "fastboot erase -w recovery" and almost had my hopes up because it said it wrote a filesystem but after erasing it wouldnt write "FAILED (remote: (FileWriteFailed))"

I dont see a way out, anyone have a clue what went wrong and how to fix it? I followd the instructions and the md5 hashes were correct
[Nexus 7 Android Development] pellajl:
Hard to say what went wrong but I had a similar experience where I couldn't load anything. In my case, I believe the formatting of partitions somehow screwed things up.

I finally loaded the stock image using the WugFresh development tool. You'll find the soft brick option on the right hand side of the tool's opening screen.

You will find the tool here: http://www.wugfresh.com/nrt/

Good luck
[Nexus 7 Android Development] pellajl:
Update:

The ROM is now running like a maimed dog. Running Google Map or Chrome basically kills the tablet.

There must be something fundamentally wrong under the hood with Lollipop . Suspect Google Services but I don't have the tools to prove it.

Despite [MENTION=5373714]freak_97[/MENTION] brilliant effort in boosting Lollipop's performance with non Google apps, I get the feeling that unless Google does a better job of making Google Services perform far better, we have come to the end of the line with the Nexus 7 2012.

What are other people's opinion?
[Nexus 7 Android Development] SkOrPn:
I know I'm using LP and not having any issues with Chrome, so it can't be a fundamental problem with LP, or everyone using LP, millions of users, would be suffering the same symptoms. It is this specific device, they all seem to be different to some degree as is apparent to every N7 performing differently on the same ROMs. Yes, I agree this N7 2012 line ended last year, lol.... Now we are just trying to follow a broken line of bread crumbs, in dirty sand... lmao

I'd like to mention, since I got this device over 2 years ago, it has never run this good as it does today on this ROM. I still want the TAB S or the N9 though...
[Nexus 7 Android Development] pellajl:
Point taken about Lollipop and probably didn't express myself properly.

I really meant to say that the fundamental problem was the version of Lollipop released for this tablet. What I was trying to say was Google Service interacting with this ROM.

What I am struggling to understand is why your experience is so much better that mine.

Yep, Tab S is looking good. Not sure about the Nexus 9 hardware platform. Its only dual core processor from what I can see.
[Nexus 7 Android Development] SkOrPn:
I been struggling for two years with that same question. I could NOT get Chrome to ever run good UNTIL I installed this last few builds. However, all over the internet you read how well Chrome on Android runs.

I think it is an extremely sensitive thing, just one app difference, or the way you or I installed the ROM, I formatted, you didnt, or you formatted and I repaired, etc etc... Or dirty flashing vs clean flashing and then having just one app different running in the background, plus someone may run at 1.3ghz while I run only Interactive at 1.6ghz or 1.5ghz using ROW. There is just a whole host of differences that can be part of that question. I never use the stock launchers either, I always use Nova. So, just because it looks like the same device, it really isn't. Its just sensitive to that sort of thing. Also, not to mention I always have my device on the charger topped off when its not in my hands, so maybe more resources are spent on a device that is always running in the 90% range of battery... idk

Another really good looking device is the couple week old Dell Venue 8 7000 Pro running with the very latest Intel Atom. I was shocked to see how fast my brothers 1.3ghz Dell Venue 8 ran with that last gen Atom proc, so I can only imagine that new Dell Venue 8 7000, which is even thinner then the TAB S, running LP would be absolutely amazing. That thing looks like its as thin as standard cardboard, lol... However, the TAB S has EXACTLY the features I have always looked for (minus the plastic).
[Nexus 7 Android Development] brandub:
Thanks but WUG was the last thing tired - its just a gui collection of adb commands but I tried it anyway in case there was some kind of voodoo in my grouper.

First message I get is 'failed to write', then 'invalid state' (fastboot disconnected), then 'no such device'

Its possible something in the partitioning went wrong and killed my memory or cpu. That sucks because 2 months ago I just bought a new digitizer/screen for it but on the bright side looks like im buying a newer device. Are the Nexus 9's worth the price or should I just get an asus ?
[Nexus 7 Android Development] techlifeweb:
That NVidia Shield looks pretty sweet to me and I'm not a gamer. http://goo.gl/Fy22Dp
[Nexus 7 Android Development] thelangosta:
I have a shield tablet. It's nice enough though I'm guessing the Dell and Samsung tablets mentioned above have better build quality. The shield does everything we need it to do. Not much ROM support but I don't really care about that since it would probably break most of the cool added features Nvidia put in there. Nvidia seems like they are cool with users unlocking and rooting.

Edit: it has front facing speakers which are now a must for me. And a stylus built in like the Note phones.
[Nexus 7 Android Development] wrkerr:
I wanted some more screen space, so I went with the Nexus 9, and I am so glad I did. It's fantastic.

The price was a deterrent for me, so I waited for a good deal to pop up on Swappa. I got the 32gb WiFi model for $300, new in box, with a Poetic case and a glass screen protector. I couldn't be happier with it!

Plus, I know when it gets old, I'll be able to install a sweet custom ROM, since Nexus devices have such good 3rd party developer support.
[Nexus 7 Android Development] SkOrPn:
The Shield is a premium device, NOT sporting a premium display and that is an instant deal breaker for me. OLED and AMOLED are the ONLY displays worth having at those price points. Viewing side by side comparisons makes this abundantly clear. One of my biggest gripes is start up booting speed (which I perform every morning out of habit) and screen brightness out side. I take my tablet hiking and biking with me and the Shield would be near impossible to see, just like my N7 is. The shields screen is also a cheap lcd, and yet its battery on time is two hours less then the Dell's. However, if I ever played games on my Tablet I wouldn't hesitate to get the Shield, but that is the ONLY reason to own it (unless its goes on massive 50% off sale, lol). Another thing about Android I like is the fact I can only use it in Portrait mode, and that Dell is clearly made for Portrait mode. Now if were talking Windows 8.1, then yeah I can see using a tablet in Landscape all the time, which is how the Shield is designed. Not considering gaming, I think that Dell AND the TAB S both beat the Shield at everything else.

However, with all this said. I do not believe I will ever see a tablet worth more then $300 to me, which is why I will stick with the TAB S and hope I can get it well below that.... someday lol. Think I will wait for the next Samsung Flagships to be released.
[Nexus 7 Android Development] techlifeweb:
Thanks for the pointers about the screen. I just can't swing more than $300 on a tablet and even that is pushing it.

I'm doing some testing on windows 10 and so far it is pretty great. I couldn't resist one of those $99 HP Stream 7. 8.1 is kind of a pig on that thing (it only has 1GB of RAM) but Windows 10 actually makes it usable. Microsoft is up to some wizardry there. However, Windows is not very good on small devices where you need an on-screen keyboard. Maybe a 9 or so inch device but on a 7 inch it pretty much sucks.
[Nexus 7 Android Development] wrkerr:
To bring this back on topic, my n7 is running great now. I installed the latest alpha with system as ext4, and data and cache as f2fs. I used Freak's "My Own Gapps," and kept everything to a minimum. See screenshot for what I'm running. Install went very smoothly.

I'm curious about the choice to use leankernel. I'm relatively new to this, but what advantages does it have over M-kernel, or others?

Thank you so much for this work. My n7 is such a pleasure to use again, for the first time in a while. I just installed this today, so I'm hoping it stays this snappy, but I'll update in a few days.
[Nexus 7 Android Development] SkOrPn:
You an Insider by chance? Ive been working closely with MS since the XP days, when they invited me to the Speed Limit Party in Seattle WinHEC 2005 (only 64 invites world wide). Since then I have been a beta tester for every OS of theirs, except for 8 and 8.1. I got a fully signed XP (64bit version) from the developers before the world even knew it had been released, and its #2 off the mass production printers in fact, along side a 64bit Bottle of Wine (yes you heard me right, lol). Currently I am a Insider, which is not the same as my BETA tester days but its sorta like that. I think 10 could be one of the most important Windows releases because for the first time Micorosft is betting their future on it. With cities like Munich in Germany fully using Linux or OS X, their free for one year deal, just might entice them to finally come back to Windows.

I on the other hand just do not like what they are doing to the Desktop scene. I'm OK with the Store idea, and even OK with the Flatness of it all and removal of the real start menu, which I can easily replace myself. But what I'm not OK with is them trying to unify OS's into one system. Mobile Phones, Tablets, Laptops and Desktops are NOT and never will be the same device. Sure maybe in 2030 all monitors will be touch, but for now I will NEVER have a touch screen on my Desktop. They should have just split off Desktop/Servers into its own fork, and had two forks (Desktops/Servers fork above 11" & the Tablet/Mobile Phone/Laptop fork below 11") simple as that. The way they are doing it is really hurting the Desktop PC market and may eventually kill it all together. I think they should have had a "Windows 7 Reloaded" with functional App Store, and much more efficient Kernel and kept in place Aero. Sure give us all the underlying improvements but please keep away the touch screen crap meant for mobile devices please. Anyway, maybe Ubuntu MATE 15.04 LTS just might entice me to leave the Windows world.... sorta.... lol

---------- Post added at 06:25 PM ---------- Previous post was at 06:08 PM ----------

Install Trickster mod and set the device to run at 304mhz to 1500mhz, its been running great for me. Also, restart once a day so the device can do an automatic trim function. I forgot what Freak told me about LeanKernel, but he had a reason to use it, I just forgot what it was... lol, I'm a big fan of M-Kernel too, but I'm using LK for now...
[Nexus 7 Android Development] wrkerr:
Wow, there are a lot of configurations in Trickster MOD, and not much explanation. Are you suggesting something like this? Is this setup right?
