[Q] This is driving me nuts..CM9/FXP123

Hi all,
Just recently flashed the new FXP123 build and the newest CM9 nightly. I am having an issue with both. As some may or may not know, the new FXP123 build came with a new kernel. This new kernel doesn't allow overclocking and seems a little sluggish.
My solution was to flash a different ICS kernel (KeICS v2, Darkforest v5, DooMKernel v3). Upon flashing a different kernel, WiFi would be broken. When I would attempt to turn it on, it just stays at "Turning Wi-Fi on..." indefinitely. When I reflashed the new FXP123 kernel, WiFi would be restored.
Are these new CM9 builds not compatible with other kernels? It seems odd that both FXP and the new CM9 nightly both have this issue. I've tried flashing the kernel before and after wiping data for a new ROM install, wiping after flashing, etc. I've tried using the different command in fastboot (fastboot -i 0x0fce flash boot <boot>.img). Nothing has worked.

Apparently FXP has changed the way wifi modules are loaded pax has said. Guess we just need updated kernels or patches. Solved?

Sluggish doesnt even begin to describe my experience with FXP123. It's my first time using CM9 so I can't compare it to previous builds, but holy crap is it slow.
Coming from CM7, I expected a small hit to performance but not to this extent. Everything takes 2-3 times longer to load or react on CM9 compared to CM7.
I hope this is just a problem with FXP123.

Try Aokp, it's latest build is based on fxp123 and is running smoothly without over clock, although I only have a few apps installed to prevent sluggishness

I really love CyanogenMod and after seeing the behaviour of some AOKP devs, I'd rather not support them.

Unfortunately the chat log was deleted but I'm sure if you dig into the comments, people have logs.
EDIT: I understand this is an unofficial AOKP port for the PLAY and is not developed by the assholes in the provided link (the same asshole who essentially stole a HP Touchpad and HTC resound from the dev community) , perhaps I should leave my prejudices at the door and try it.

I agree with trying it don't let the conduct of one or two of them take away from romans amazing talent. And as you said it's unofficial, so support our devs here.

Pax will be releasing new ROMs and Kernals shortly I believe that hold the old WiFi modules which should work for you guys. But noticed since I flashed the last kernal provided by FXP I have seen massivve improvement. Litrally my phone was on 30% battery. Put my phone next to my bed and today morning woke up seeing the battery was only down to 25 percent. So then I put it in charge and in 1 hour I see the phone's led is green indicating fully charged and surprizingly enough it was fully charged.

Which jelly bean rom has the least bugs?

I would recommend CM10 using SGT7 enhancements by twa_priv

And I have been very pleased with EyeCandy. The ROM's title speaks for itself, it is simply the sexiest ROM out there.

I have been using eyecandy and its great.
Sent from my DROID2 GLOBAL using xda app-developers app

I've found that although jandycane has lots of features, hashcode's ROM is more stable.

I have been using Hashcode's release. From what I heard it is the most stable.
When life gives you tech....Make use of it.

I flashed JellyCane last night and its a really nice ROM. Ive found zero issues in my 6+ hours of testing after flashing it last night.

I'm using twa_priv's and it's working very well. I still get some crashing errors whenever I mute the volume and cannot install the Kindle android app (error -24). I've had Chrome crash once or twice and had the device spontaneously reboot a couple times but otherwise it's working way better than how Amazon shipped it to me.
I'm following all of the JB ROM threads and it sounds like they are roughly equivalent in terms of stability.

What build are you on that crashes when you mute?

Both the 7-23 and 7-28. I just reflashed 7-28 and wiped cache / dalvik to be sure.
I had the problem with the stock volume widget and now also with the Volume Control app when I slide the volume down to zero percent.
Anything I can do to gather more info? Am I the only having these muting crashes?
I just tried it again with the stock widget in the status bar (tablet mode) and hitting mute does not produce the com.android.phone errors; only when you slide the volume down to zero.

Hashcode's was a great jumping off point, but I think Jandycane is the way to go now. Very stable, almost all the features you could want in a ROM. Google Now is fc'ing for me, but I just use the browser for search anyway.

How stable is it would you say? Enough to use as a daily driver? I still have Gede 1.7 for my girlfriend's KF, but thinking about upgrading to a jelly bean rom. Just wondering if they're stable enough yet..

Hard to answer since it depends what you need to work, but I'm extremely happy with the stability. I use the ROM primarily for chrome, gmail, google reader, tapatalk, boid (twitter), youtube, google+, goodreads. All that stuff is working great for me for at least a week of heavy use. I get some occasional crashes/reboots but not more than once per day.
I haven't tried any games or the Facebook app. My primary disappointment right now is that I can't get the Kindle android app to install. It's ironic that I can't use my Kindle as a Kindle.
If you want to test the waters I recommend going the FFF dualboot route. Put one of the JB ROMs on the main partition and Gede on the alternate. Minor hassle to reboot to the other ROM but also amazing that all of these great devs have made Amazon's limited device into something ridiculously versatile. My formerly dusty KF has become my primary device!

4.2.2 The bad

Well all things were fine on 4.2.1 and then this update comes,
This is what i noticed so far,
1.Phone is EXTREMELY laggy when downloading from play store
2.Browser quick controls are bugged
3.Lots of launcher crashes
4.Alarm icon in the notification disappears while it's still active
5.Random lag spikes while navigating in de drawer or homescreen,
As far as i go, this is the laggiest jelly bean version, maybe google just got lazy, or they're working on another version of Android (fingers crossed)
EDIT: I'm not talking about custom roms and such, and i'm not willing to flash, i like stock

First:
Do a full wipe!
Flash STOCK ANDROID JB 4.2.2 (I mean stock, and not CWM flashable stock ROMs with root..)
Use stock Android launcher (Just stock, not modded or anything else)
And then Stop complaining!

I'm on cm10.1 4.2.2 and is probably the smoothest ROM I have ever been on.

1. Use a custom kernel and tweak the read ahead buffer size. With sio io scheduler and 256k buffer size i made the lag minimal for me.
3+5 : use nova launcher and it will be fine
4: it works fine here, make sure you do clean installs.
As a last advice I must say to flash the factory image via fastboot. It is absolutely fine with no issues. I installed it on 2 gnex' already and no problems with lag.

Stock android is far away from perfect now. JDQ39 is nowhere near rock stable JZO54K. My friend. Scrolling lag is not the matter of clean installation. I've tested five 4.2.2 based roms, including stock all of them lags as hell after a while - it can be one or two days or couple of hours. Actually it's been the most evident of stock and it concerns scrolling between homescreens, lockscreens, recents. A lot of people have experienced it and it's been already reported to google issue tracker. I've already tested stock, cm10.1 m2, PA 3.1 0309, XenonHD 6.0 - all of them lags after a while. At the moment I am testing Purity and I haven's seen lag for two days.
Te easiest way to reproduce the bug. Please do not reboot your devices, and do not change wallpapers for about two days.

Same here, on CM10.1 Play Store is now smooth but was bad on XenonHD.

Well I don't understand where do you see the lags. Because I don't have any lags on my nexus.
The speed also depends what kernel you are using and how much free Memory you have on your nexus..
I'm using my own ROM which is based of stock Android ROM and I have actually never experienced any lags.
Yesterday I got few apps after using apple's BT mouse and when I set up multi users.. But all the lags went away when I rebooted.

How do I do this?

Not sure if this has been discussed or not I searched and found many bugs but none that meet this specific issue.. I noticed that since I updated to the 4.2.2 leak on my Toro Nexus there have been a few issues:
Audio from the pogo pin dock stopped working.
Car mode goes off and on randomly as well as the charging bolt when the phone should be charging.
Phone goes into daydream mode even when not being charged..
Turning on bluetooth randomly reboots the phone on occasion and other random bugs.
I think I'm going to flash back to the previous OTA. I'm stock unlocked, unrooted, just the way I like my Nexus (for now). In no way is this a complaint, more my observations and a last shot in the dark to see if anyone has overcome these issues in the latest leaked "OTA."
On a side note, other than the dock and power issues, everything has been smooth. No lag etc...

Ok so I realize I don't know how to do this without resetting all data. From what I've read, the only way back includes wiping all data. Am I wrong? Is there a way for me to go back without wiping? I'm not super versed in all things Android but I think I recall flashing back to a previous OTA in the past to get another OTA to work without wiping. I can't find that thread anywhere so I'm probably mistaken. Any help?
Edit: I re-read http://forum.xda-developers.com/showthread.php?t=1626895 and determined that it can be done without wiping for folks that aren't noobs. I consider myself a noob at this point so I'm stuck with this 4.2.2 update until I find an easier way.

It's the same as flashing a rom! Use Titanium backup to backup the apps, and custom recovery to wipe data/factory reset, cache and dalvik cache. Format /system, /data, /cache , and downgrade with the toolkit w/o format when it ask. So for less than an hour you will downgrade, and keep music, videos and photos. So the only thing you lose is programs, but you can restore them whit titanium, and that is!

Lags what I am talking about is low fps scrolling that appears after some time of normal usage. I've never experienced it on 4.1.2 or 4.2.1. It has nothing to do with the kernel. (BTW aren't we talkin about the stock one?) Problem is still present on custom kernels and even OCed CPU. It looks rather like some sort of memory leak. Reboot or changing wallpaper is a workaround solution for this issue. So yeah if you reboot your device quite often you most probably won't see this bug.
If you want to read more about this issue visit this thread:
http://forum.xda-developers.com/showthread.php?t=2178962
Except this bug I really like the 4.2.2 rom, these new features. I consider it as an improvement from 4.2.1.

I agree, 4.1.2 was polished more. 4.2.2 is better then the initial 4.2 release, but still has a way to go. We'll see what IO brings soon.

Ok.. Hmmm.....
Are you using custom kernel?
And which apps are running in background? E.g. Currents, Google+. FB...
And if you use custom kernel then make sure you use CPU governor that doesn't make Android slower or laggier..
I have actually never had any lags on my Nexus, I use 100% stock kernel, sometimes CM's kernel. I have free memory 2,10 GB of 13 GB (16GB GNex)..
Also I recommend to use some cleaner apps to delete unnecessary files..
For cleaning a bit my Nexus I use "Mobile Care" on Windows it is "ASC"
Which deletes e.g. Cache and junk files..

Discussion/Poll for best rom performance

We're all here because we want better roms than what our phones came with, upgraded roms etc. Idealy we'd want the most stable version with the last junk so it's the most responsive. As I upgraded more and more roms, I started to feel that the phone is showing it's age in processing power, and just like computers, you can't just install a newer stronger OS on older hardware, at some point you aren't gaining performance, you start to lose it because the hardware is struggling to keep up. I went from stock to 4.2 roms, then 4.4 roms, (pacman, mokee, CM, etc etc ). I eventually went back to 4.4 stock and it gave me the least trouble and quite snappy. Of course it had the OEM bloat from Verizon. Its been going strong for maybe a year, and now it too is starting to crash with a lot of bugs, probably from installing so many apps, but also I see a lot of built in apps taking up memory. So my main question is, if you still the Razr M and still using roms, what have you settled with ? What has been the most stable and fastest for you so far? For me so far it turned out to be the stock 4.4.2. So my options are to start over again with a fresh 4.4.2 or maybe a stripped 4.4.2, or one of the new 5.1 builds. I mainly use it for Navigation + music + calls, generally nav + music at the same time. Someone mentioned that CM12.1 couldn't handle that because of memory issues so that scared me off, but I love the CM12.1 on my galaxy tab pro. I do use the Bluetooth when im riding, and the camera from time to time, and the stock just had everything working.
If I can't find a stable build/rom, it might be time for me to move on to a newer quad core 2ghz + phone, browsing on the razer m is ok, but admittedly a little slow. The battery isn't what it used to, but it still gets through the day, and there are (albeit dodgy quality ) replacement batteries on amazon to hold out longer... The phone was basically free over 2 years ago, I've never been one to shell out $300 for a phone, but that oneplus one is mighty tempting to switch carriers for. ATT failed me on signal at this house so Verizon has been great, but i'd be willing to try tmobile if im forced to pick a new phone.
TLDR: Which rom has been the most stable for you ? ( rom name and build/version ).

Stock 4.1.2 (with uninstalled bloatware), as 4.4.2 has broken audio on (some?) Rev.B phones.

I have been on stock jelly bean, rooted stock kitkat (debloated with permissions removed for batt life), cm12.1 (our device is just too limited) and now cm11 snapshot 12 on kitkat boot loader. So far cm11 is my favorite.
Sent from my DROID RAZR M using XDA Free mobile app

For me stock kitkat debloated runs smoother, although is very sluggish sometimes: for example when I'm swapping messenger, whatsapp and running music player at the same time, it's almost impossible...
Ice tested cm when was 5.0,and was terrible. Pac man Kk, not as good as stock.
Sorry for this ugly link, I'm on my phone, but this post and the thread overall has a lot of good tips:
http://forum.xda-developers.com/showpost.php?p=53724034&postcount=17

In the last 2 and a half years I've been through:
Stock 4.1.2 (rooted after 1 day, debloated, Safestrap)
Eclipse Rom v1.2 (Safestrap)
CM10.1 (Unlocked BL)
CM10.2 (Unlocked BL)
CM11 (Unlocked BL, JB Kernel)
Stock 4.4.2 (rooted, debloated)
CM11 (Unlocked BL, KK Kernel)
CM12.1 (Unlocked BL, KK Kernel)
Best user experience for me? Sad to say but I had it with the Stock 4.1.2: overall smoother than all the rest. Then after some months my Razr M started a bootloop, so I unlocked the bootloader and tryed the CM ROM: the CM Power Widgets were an overkill at the time (mainly the 2G/3G toggle)...
After all the CM ROM that I've used, the second place goes to CM11 (with JB BL).
Right now I'm testing the latest CM12.1 builds, and they seems ok. I've installed onlyt the apps that are strictly necessary to me (gmail, maps, onenote, osmand, dropbox, wikipedia, Room Toolbox Pro, SuperSu, calendar, meteo, etc...). Everithing seems fine but I liked more the old KK style (lockscreen, quick settings). Everything is working, even if sometimes the data, Wifi and GPS signals are erratic. The performance are acceptable too.

So far a vote for CM11, and stock unlocked debloated. That's what i was heading towards too, stock debloat, and probably 4.1 it still has the best performance really. I mean the custom roms look great and all, but at the cost of performance which, after the initial wow factor, I think we would all prefer performance. Back when I had my HTC my favorite and most stable rom was jacko's most basic slim version ( he had like 1-5 tiers of peformance and features ). If I go back to stock and it lasts me another year or two i'll take it.

I'm trying out CM11 Snapshot 12 right now. I was already on 4.4.2 stock with unlocked kk bootloader so it made sense to try it first. Its already a lot smoother than what it was, freeing up half the memory. I noticed the dialer doesn't go all the way up sometimes, you have to push back and hit the keypad icon again. Otherwise very smooth so far. I'll report back after I get some use out of it and if I ever decide to go back to 4.1. I might need a new battery though, if I'm using it it doesn't last through a day.
*Update - I went from having basically no free memory left to about 50% free memory. I think my battery life increased dramatically with so much less running in the background. Maybe by 20-50%.
I took one phone call and updated a few apps, about mid day through the work day. was 12h by the end of the day and a few calls and some browsing w/o having to charge. Definitely gave new life to the phone. Very minor dialer bugs, sometimes the number pad doesn't come up correctly the first time.

Android 4.1 has various security issues that won't be fixed anymore, so that's not really an option.
But I don't think there are big differences in battery life anyway (see this).

After testing a lot of CM11, using Performance settings, changing memory settings, having a very poor battery performance, I've come back to the 4.4 backup with all the apps I had. The difference was incredible, now my phone feels snappier than an iPhone, and sincerely, i don't know why!! I think that doing a restore sometimes can help a lot.

Yeah the last time I did a fresh install of 4.4.2 stock it was great. After a while though with all my apps installed + the oem bloat the phone had very little memory left and became sluggish. My best options right now seem like going back to stock, either 4.1 or 4.4 and trying to do manual debloat.

I did a fresh install of CM11 again but still didn't fix it. I still had the occasional dialer error and wifi would only work upon boot, after disabling, it never reconnects to any wifi. Battery was still horrible. I went back to stock 4.4.2. RSlite would not work on any version on windows 8.1 64 bit. I had to do msfastbootv2 and was able to restore to stock 4.4.2 However upon booting, it wanted to update to 183.84.15 but failing. It would say there's an update, download it, reboot, and automatically boot into recovery. I would select reboot and it boots in, sometimes saying update complete but it hasnt' actually updated anything. I eventually gave up and started over, this time using stock recovery, not logging into my google account so it doesn't start downloading all my apps, no supersu, no gapps, and it successfully updated to 183.81.15. At that point using mfastbootv2 I installed twrp 2.8.5, rebooted into recovery, installed gapps and supersu. Then used titan to debloat using http://forum.xda-developers.com/droid-razr-m/general/complete-debloat-list-droid-razr-m-t3045731 , removed most of the things on that list, particularly anything I didn't use that I saw running. I also installed Greenify. After about a day I started noticing the google play services issue using a majority of my battery. I downloaded App Ops to disable google play services wake permissions. I am amazed at what happened. I feel like I have the original batteries back. I received 2-3 short calls today, and 2 browsing sessions, installed some apps (facebook lite), and I still have a lot of battery left, normally it would be over half gone. Going home after that much use and still having over 70% of battery left is nothing short of amazing and I no longer feel like getting a new phone. I was very close to trying the Droid Turbo.
TLDR: Got original usage/battery back with stock 4.4.2 + debloat (backup & Uninstall with titanium ) + App ops to fix google services wake battery drain + Greenify. I don't know how much Greenify is doing, I attribute most of my gains from debloat + fixing the google services issue. Before App Ops you'd see a giant bar at the top of Google Services instead of screen.

Still odd you having WiFi issues. I don't I did learn recently that my Bluetooth does not seem to be fully functional.

So far, all I've tried (and stuck with) are stock 4.1, stock 4.4.2, and CM 12/12.1.
Stock ROMs were fairly snappy, but I was always a little fearful (irrationally, but still) of trying to debloat while on 4.4 (and I remain fearful of downgrading the bootloader). This is my daily driver, though, and it must remain so until I become eligible for a newer phone in December (or I can pick up something better, used, for extremely cheap ...).
I have been toughing it out on CM 12 since late January. I like several of Lollipop's UI changes and new features (as well as CM's additions over stock), so despite some frustrations with bugs and somewhat-laggy performance, I haven't felt terribly compelled to try CM 11, or to go back to stock 4.4.2. (At least, not all the time; there have been moments of extremely slow response times where I've wanted to wipe /system right then and there and flash CM 11. I have stuck with 12 so far in hopes of improvements on the way to the first snapshot.)
Also, vo_danh, I was the one who reported about the issue with simultaneously running Maps and Play Music. I don't think I've ever gotten a phone call while trying to run those, but suffice to say that I have enough trouble with (occasional) lag when a call comes in.

If you're already on the kk boot loader like me, you don't need to downgrade the boot loader for cm11. Its been almost a week and i am still just amazed at how well this config is working for me. The battery life is like new again. Don't be afraid of debloating with titanium, since you can back it up first before unisntalling, if anything goes wrong, simply reinstall the backup. As a safety, after I restored to stock 4.4.2, updated to 183.84.15 OTA, I created a TWRP backup, so if anything goes wrong I can just restore it with TWRP instead of doing through all the steps to go back to stock. I didn't remove everything that was on that debloat list, just most things from verizon or anything I raw under 'running' list that I didn't need. It's so stable and fast. I would only move to a stock + debloat rom now for this phone for now. If I had a stronger phone there's no doubt i'd be using Cm12.1 but for now, this phone isn't meant to handle it smoothly and the wifi issues i had with Cm11 just make it not worth it. All wifi issues are gone now on stock. I didn't have wifi issues on any of the other roms either.

We're all here because we want better roms than what our phones came with...

1. One that the phone came with, with a little tweaking. 4.1.2 deodexed and debloated. Best usability and battery life. Slows down with heavy games tho so i unlocked the BL.
2. KK debloated. 4.4.2 i think. better in many respects but I sorely miss the Jb camera. It was wonderful. Battery life had come down a couple of notches.
3. Currently running the Bliss rom (5.1). My earpiece and mic doesn't work with the latest update. lol.
Edit: Call issues in the Bliss rom have been fixed. It's a solid rom and deserves a strong recommendation.

Galaxy Nexus is very slow and laggy and refuses to be any faster

I've had my galaxy nexus for a while and i've put up with the slow response and lag up until now. Most of my apps take forever to use and other just don't even work anymore because there's too much lag. If i even have more than 1 or 2 apps opened, my phone (for whatever reason) just can't handle it, heats up like crazy, and just drains so much battery that I have to take out my battery and wait for a few minutes just so to let it cool down and reset it.
I've tried a few of the better options which is to root my device, get slimkat android 4.4.4 (which kind of worked), and get lagfix premium along with greenify. But after all of that and trying a few other options, my phone is still as slow and laggy as ever. what else is there that i can do? If I need to provide any other information on my phone, let me know and I will reply.

So just to clarify, when use installed your roms you did a full clean wipe, yes?

oh wow u are facing the exact same problems as me though im on aokp rom. it got so bad till i decided to come here to look for an alternative solution too! was hoping to find a new lightweight rom to see if it solves the problem since aokp is like long dead.

so you already tried the slimrom, that's normally my solution to phones being slow I personally use ziyan's cm 12.1 beta builds and for me they are really fast and pretty reliable, they've for just a few minor issues I don't mind, maybe that's something for you to consider
