Well

This is because i had failure: i was trying to install CM 12 vs before PA version but after a full wipe that i was believing could be enough ...

OK now i am completely stock 4.4.2

I will install recevery TWRP

FULL WIPE

FLASH rOM with CARCOSA kernel

RESTART in RECOVERY

FLASH CM12 GAPPS

RESTART in system

is it OK ?
[Nexus 7 3G Android Development] jfmcbrayer:
So I cleared the data for Google play services, flashed the latest GwT repack, flashed the CM GAPPS, and set up my Google account again, and face lock is working.

With the PIE change, mosh works, Lil Debi still has problems with a shared library in its LD_PRELOAD environment, but ultimately, that's on them to deal with. You've now done everything the ROM developer can reasonably be expected to do to accommodate them..
[Nexus 7 3G Android Development] Synman:
You can even flash them together....

Gwt then gapps and wait forever first boot (up to 10 minutes in my experience)
[Nexus 7 3G Android Development] paolocorpo:
With PA GAPPS your suggestion is OK ( i knew this option for several .zip until 10)

But with CM 12 GAPPS i was obligated to reboot recovery otherwise the GAPPS instalaltion fails :(

I finished all but ... facelock there is not ;):confused: ... and i am worried if there are other features not available ... ;)
[Nexus 7 3G Android Development] Synman:
I don't know what to tell you. Myself, and at least one other are not having the same problem. Did you download GAPPs directly from teamandroid or the androidfilehost link? Perhaps they have different MD5s.
[Nexus 7 3G Android Development] paolocorpo:
YES

I downloaded CM12 GAPPS from your suggested link

Could I try this workaround ??

It is similar (not exactly the same) to procedure done by jfmcbrayer at post #245

Will be this proposal workaround wiping my app and data ??
[Nexus 7 3G Android Development] tig3r81:
Hy Synman wonderfull rom. I had the same issue of Paolocorpo:if I flash rom and gapps toghether, gapps don't install, but fails, if I reboot into recovery after installed your rom gapps is OK.
[Nexus 7 3G Android Development] Synman:
odd as it worked fine for me... fortunately it goes against my own instructions :)
[Nexus 7 3G Android Development] evolvent:
IO perfomance in last kernel is poor. How to disable fsync?
[Nexus 7 3G Android Development] paolocorpo:
Dear Synman what do you think about my proposed workaround.?
[Nexus 7 3G Android Development] Synman:
It cant hurt to try?
[Nexus 7 3G Android Development] paolocorpo:
sure but ... will i have wipe of data ? I just setted my tablet ... :)
[Nexus 7 3G Android Development] jfmcbrayer:
You'll have to try it to see. I didn't wipe data, but I did wipe system (flashing new GwT build).

---------- Post added at 07:48 AM ---------- Previous post was at 07:30 AM ----------

I had the disable-fsync and dynamic-fsync patches in earlier versions of carcosa-kernel, but they caused some instability. I could try again, but I'm not sure it's actually a good idea. Disabling fsync is not a panacea for IO performance; it's a risky trade-off, and the same bits still need to get written to disk eventually. You might rather try a different IO scheduler and/or tweaking the IO scheduler parameters.
[Nexus 7 3G Android Development] paolocorpo:
The option face lock there is :)

Simply it has been relocated in different menu with LOLLIPOP

ALl is OK
[Nexus 7 3G Android Development] jfmcbrayer:
For those having IO slowness, try carcosa-a33-lp-anykernel.zip. It adds the SIO IO scheduler and makes it the default. (I seriously need to find the time to update these on my own development thread.)
[Nexus 7 3G Android Development] paolocorpo:
Do you suggest a detailed setting with Trikster app ?? Or we have to use the setting by default ?
[Nexus 7 3G Android Development] jfmcbrayer:
Please do feel free to experiment. The defaults are mainly what I recommend, except that they overclock the CPU - - I lower the maximum back down to 1300000,but raise the minimum to 204000.
[Nexus 7 3G Android Development] Synman:
Looks like i have another repack!

Sweet
[Nexus 7 3G Android Development] paolocorpo:
Dear Synman ... what's new ??

I have already installed your last version with Carcosa bundled and i have updated kernel from a-32 to a-33

Is it enough ??
[Nexus 7 3G Android Development] Synman:
I'll merely be rebuilding the image with the updated carcosa kernel.
[Nexus 7 3G Android Development] paolocorpo:
OK many thanks

So i am already updated

I am noting some lag ...

I am not sure about the cause because have not used wo Carcosa Kernel ...

What your idea ?? Do you have lag ??

Antutu gives to me a score around 23764 ... so small :(

With M-kernel a73 iti became 23891 ... so small :(
[Nexus 7 3G Android Development] jfmcbrayer:
My experience with Lollipop so far (the only LP ROM I've used is GwT, but it's consistent with what grouper users are saying about stock):

Within any app, everything is fast, noticeably faster than KK. Switching apps can be very, very slow. Like four seconds for the task switcher to come up. Using the deadline or SIO IO scheduler mitigates this slightly vs using cfq , bfq, or row, but only slightly. It's as if, instead of stuttering, LP just waits until it can do something smoothly.

I'm kind of torn. I really like the looks of LP, and a few of the new features like trusted device, trusted face, but the performance issues and the fact that several apps I like don't work on it yet means I may go temporarily back to KK. I haven't decided yet.
[Nexus 7 3G Android Development] Synman:
GwT + carcosa Kernel Synman_GwT_carcosa-a33-tilapia-LRX22G-user.zip is up!

My DEB nexus is in my car (engine in the process of being rebuilt). Just as soon as I have it back (another week or two) I'll be moving on to DEB builds. I don't anticipate doing much more tilapia work until the final build is released.
[Nexus 7 3G Android Development] evolvent:
There are no io perfomanse issues in lollipop. There are slow flash memory in tablet. In Asus tf700 with tegra3 slow memory too. So only one tweaktweak will be help for us - turne off fsynk or turned on dynfsynk. Try m-kernel to see this
[Nexus 7 3G Android Development] paolocorpo:
Is m-kernel ready for TILAPIA 5..2 too ??
[Nexus 7 3G Android Development] jfmcbrayer:
I believe it is. There is not a separate kernel for grouper vs tilapia.
[Nexus 7 3G Android Development] HighlanderZA:
Just installed a73 and it's working fine!

Thanks [MENTION=3129719]Synman[/MENTION] needed a kick in my @$$ to do some fiddling with my Nexus - it's been stock for way too long!

Nice ROM!! From Pics of Lollipop, I thought I'd hate it, but on the Nexus I like....... !!! :D
[Nexus 7 3G Android Development] evolvent:
but I must say that m-kernel or any other (except carcosa) not have patch for xmm_baseband wakelock problem. so on m-kernel you will have much bigger battery drain in sleep
[Nexus 7 3G Android Development] paolocorpo:
What about lag and performance ? Is it better ??

---------- Post added at 10:14 PM ---------- Previous post was at 10:12 PM ----------

I Will test with betterbatterystats app if wakelock is present

With KK Franco kernel too had baseband patch
[Nexus 7 3G Android Development] paolocorpo:
I remade antutu test

It is not better than with carcosa kernel...
[Nexus 7 3G Android Development] naeco:
Hi Synman!

Thanks for the great work!

I'm gonna try it in a few hours. One question though. In your instructions, you pointed a link for the latest Twrp for Nexus 7 wifi (Grouper), while there's also a version for Nexus 7 3g (Tilapia). Do both work the same way on N7 3G?
[Nexus 7 3G Android Development] paolocorpo:
NO for sure

You have to download the right version of TWRP for your TILAPIA
[Nexus 7 3G Android Development] Synman:
Not entirely correct. Tilapia uses the grouper board. Only difference is the inclusion of the modem.

Either will work fine until we have a new baseband.
[Nexus 7 3G Android Development] paolocorpo:
OK this is new for me :)

BASEBAND of TILAPIA is the same from JB 4.3 until today with KK 4.4.4 (version 1231_0.18.0_0409)
[Nexus 7 3G Android Development] Marasta86:
F2FS Version

Hi Synman!

I'd like to thank you for all your work! I read a lot of report about this ROM and i'd like to flash on my own N7 3G.

I just want to know if you are going to release a F2FS version of this ROM, which maybe will increase the performance of the system.

Thank you anyway, I'm going to try this new Lollipop! ;)
[Nexus 7 3G Android Development] Undesirable:
The problem with an F2FS version of this ROM is that the author recommends that stock be installed for best results, and the stock ROMs do not support F2FS.
[Nexus 7 3G Android Development] JROppenheimer:
Thanks a lot for this. This made the device usable again. All in all effort 1h, as I had nothing prepared (adb, drivers, fastboot, ...). Had an app crashing once in a while, will report if I find errors. Until then: Many thanks!

As I really appreciate this: Anywhere, I can donate a beer or two, or twelve?
[Nexus 7 3G Android Development] Synman:
Performance is NOT the driver behind my recommendation. Simplicity for the masses is the reason.

With a little time I'm sure someone could get GwT running with F2FS...
[Nexus 7 3G Android Development] rockafellor:
Anybody experiencing heavy lags after tablet has been on for a day? A reboot fixes it for me.
[Nexus 7 3G Android Development] Undesirable:
Well we've come one step closer, because now TWRP v2.8.4.1 allows you to convert partitions in Tilapia to F2FS, so we no longer have to flash a modded recovery.
[Nexus 7 3G Android Development] paolocorpo:
Ciao

Can you give an example of heavy lag ?
[Nexus 7 3G Android Development] rockafellor:
Hello! System reaction is very slow. When opening app drawer, it takes 10 seconds until anything happens.

Installed m-kernel Yesterday will tell you more if it helped
[Nexus 7 3G Android Development] paolocorpo:
i used Carcosa for few days

I can confirm that it is able to fix the issue of kernel wakelock named BASEBAND_XMM_POWER (as Franco in the previous version for KitKat)

But i can confirm that M-Kernel a-73 is more performing
[Nexus 7 3G Android Development] rockafellor:
I was using carcosa which was already included in your rom. Is there a newer version? Seem like it is a kitkat kernel from what I was reading. Correct me if I am wrong. Thank you
[Nexus 7 3G Android Development] paolocorpo:
Carcosa bundled inside this rom is the last available # 33 by jfmcbrayer (as Synman said in post #266)

Carcosa exists for different version of android (JB, KK) and for LL too

I spoken of lags with Carcosa in post # 264 and jfmcbrayer gave me a feedback with the post # 265
[Nexus 7 3G Android Development] jfmcbrayer:
I've mentioned my experience with Lollipop performance earlier on the thread, but I'll recap. Individual apps are fast, but anything that switches tasks is very slow, and especially the task switcher. It looks like this is just an AOSP problem, as it affects basically everyone on grouper, tilapia, and several other devices as well. The app drawer and the task switcher are faster when you've used them recently.

I installed M-kernel for testing as well, but it didn't solve any of the performance problems that actually bother me. Metallice's CPU governor is very good, though.

If anyone has concrete suggestions for improving carcosa kernel on Lollipop, I'm glad to take them. Either here, or in the dev thread for the kernel.
[Nexus 7 3G Android Development] JROppenheimer:
Not at all. Also not the mentioned app drawer lag. Tablet runs smooth. Even streaming fhd content vie LAN works without lags. Totally awesome.

---------- Post added at 09:04 PM ---------- Previous post was at 09:01 PM ----------

From what I can see: I had the tab on for over a day now. Installed like a maniac, tried games, video streaming, etc. I opened the appdrawer, it showed up right away. Also the task manager showed up right away, as well als the app swithing worked without any delay.

I've had mine sleeping all week. Will post some pictures and post personal experience tonight / over the weekend.
[Nexus 7 3G Android Development] 3XTR3M1ST:
Is your latest release supposed to be related to the 5.0.2 stock released couple of days ago? Or is this just pure coincidence that both you and google decided to use the same release name?

https://dl.google.com/dl/android/aosp/nakasi-lrx22g-factory-2291c36b.tgz
[Nexus 7 3G Android Development] Synman:
Nakasi == grouper == WiFi

LRX22G was meant for nakasi .. I rebuilt it to work with nakasig.

Rumor has it the official nakasig release will be 5.0.3

/Data F2FS

Hi ppl,

I've installed this ROM on Nexus 7 3G with this kernel http://xdaforums.com/nexus-7/orig-development/lollipop-phantom-kernel-r1-t2943679 , convert /data to F2FS and works like a charm.

Any other experience you ppl want to share on something like this?

[Nexus 7 3G Android Development] paolocorpo:
Dear user,

if i perform the conversion od my data to F2FS today (all the app have been installed, etc) will i loose all data ??

I gived a look to 3D of Phantom Kernel suggested by you; it seems that it was created for N7 GRUOPER only
[Nexus 7 3G Android Development] hcarrega:
Does anyone use one specific governer?
[Nexus 7 3G Android Development] jfmcbrayer:
On stock, interactive is basically the only viable choice. On carcosa or oxydo, either interactive or smartmax are good choices. If you are using M-kernel, then touchdemand is the better choice.

---------- Post added at 09:12 AM ---------- Previous post was at 09:07 AM ----------

You do have to format /data to use f2fs, so yes, you would lose your data.

As to the referenced kernel, generally, grouper and tilapia use the same kernel. It would be possible to compile a grouper kernel that cut out the tilapia radio drivers, but the stock grouper kernel doesn't, and neither do most custom kernels.
[Nexus 7 3G Android Development] Synman:
AOSP only publishes a grouper kernel. The tilapia build merely uses the grouper zImage.

If the new version of twrp does an in place conversion you can possibly preserve /data.
[Nexus 7 3G Android Development] Synman:
Here's a week of primarly sleep ... closer to 8 days. would've been more but you can see I had some usage day 1.

Is the phone functionality supposed to work, as in I should be able to make and receive calls on the nakasig?

Whenever I tried to make a call, the call ends immediately after entering the number and tapping the call button. If I were to call in from another phone, it gets the dial tone on the caller but the nakasig never shows anything.
[Nexus 7 3G Android Development] JROppenheimer:
As far as I can recall without taking a look, first post or so sais, that calls are not working, I think due to radio issues. But basically: No - calls are not working at the moment.

*edit: Just took a look:

Regards.
[Nexus 7 3G Android Development] paolocorpo:
Yes i acan confirm

Calls are not working but it is not an issue of rom .. it is basically a limit of NEXUS 7 3G and LTE verison
[Nexus 7 3G Android Development] Synman:
I use a SIP provider with the built-in dialer with no issues. But yeah, sorry ... our tablet will never have GSM
[Nexus 7 3G Android Development] JROppenheimer:
Haven't tried SIP yet. But should be an idea :)

Why is it, that GSM won't work? What about when there exists a factory Image for the 2012 Nexus 3G?
[Nexus 7 3G Android Development] Synman:
There is no voice GSM capability in 2012 3G or 2013 LTE tablets... literally no circuit connecting the modem to audio. A few of us bricked our modems a couple years ago trying.
[Nexus 7 3G Android Development] dwny:
Excellent ROM...Thank you

I've gone thru several Lollipop ROMs and they were all sluggish on the N7 3g

I thought I would have to go back to 4.4.4

This is the 1st ROM to perform VERY VERY well, I was surprised :fingers-crossed:

I'm on T-Mobile, this device has never made calls without using SIP.

I had this device since it's release

[Nexus 7 3G Android Development] g_magic_tsp:
USB/OTG and fast charge

Thank you for the awesome ROM and Kernel. I just started getting addicted to XDA and changing up ROMS and Kernel. I was wondering if there are any plans to include USB/OTG and fast charge to this kernel. I am looking at making my nexus 7 into a device that I can take with me in my car to run waze, tablet talk, nav, ODB diag and just use as a regular tablet when I am traveling. I have loaded this ROM and it works as described and it got rid of the annoying "unfortunately bluetooth share has stopped" that I could not seem to find a fix for with kitkat.

Thank you for any help that you can provide.

f2fs

Hi

Can I use the app "convert to f2fs" to convert "Synman_GwT_carcosa-a33-tilapia-LRX22G-user.zip" to an f2fs ROM?

I have already used that program and installed CyanogenMod 11 (I converted cache , system and data to f2fs using multirom twrp recovery) and it works really well.

Thanks
[Nexus 7 3G Android Development] Synman:
You can try. Let me know how it goes.
[Nexus 7 3G Android Development] thang vu:

I have tried CM12 but it still laging sometimes.

this rom is better, i think

thank you for your work.

I heard a lot of people talking abt f2fs but i dont get it much. and i dont know how to install f2fs into my nexus

if u successful with your work. could you tell me step-by-step to do that.

OS not installed

hey guys

i have a little problem when flashing this rom

these are steps i made

First: I go to wipe. then wipe factory, next, go to wipe advanced and then, wipe everything except storge

second. i flash the rom

The problem is after flashing rom, i reboot into system. I got a notification that OS not installed :v

I did not know what to do. I re-do those steps above and got the same result

after all, I ignored the notification that OS not installed, I boot into system. It worked. OS worked well.

But i dont understand why i got that message??

Seems like finally the official LRX22G is available for the Nexus 7 3G (2012) edition.

https://developers.google.com/android/nexus/images#nakasiglrx22g

The current Synman build here dated 2015/01/08 is based on the WiFi release with 3G function patched in I guess?

Hope to see a build that is based on the official 3G Lollipop release by Google :)
[Nexus 7 3G Android Development] JROppenheimer:
Thanks for sharing! But I have to say: this build works so flawlessly, I just don't know why I should flash a newer version :) that's why I would have to ask: wheat improvements could there be, building from the official ROM?
[Nexus 7 3G Android Development] thang vu:
This ROM is made based on grouper nexus.

Though this ROM work perfectly now but it will work more perfectly if built from official ROM, I think

As you know I really have appreciated your effort to create a new version of Carcosa for N7 TILAPIA with LL in order to fix the issue of Baseband wakelock

Your KERNEL at now and under my knowledge is the lonely that is able to do

But i would like to have too:

More performance (i noted several small lag ... acceptable .. but they are present) and double tap to awake or swipe to sleep ...
[Nexus 7 3G Android Development] Synman:
NOT TRUE

GwT LRX22G is built using the tilapia LRX22G build target. The ONLY thing that is not compiled with LRX22G source is the RILD. Additionally there was no xgold modem driver available from Google at the time and I used the same KK version of it.

If I re-release, those two items will be the only changes. I may even just release them as a patch, if I release another LRX22G update at all.
[Nexus 7 3G Android Development] JROppenheimer:
Could that maybe just be an issue of missing computing power? The N7 2012 is not really the strongest device as far as I can tell.
[Nexus 7 3G Android Development] Synman:
I will mention this.

I'm seriously considering a Dark / Customizable LL theme. This is something I'd likely do at a global level while working on my next DEB build. If I do deliver a customizable theme framework I will rebuild.
