DSP error
not sure if it's just me but everytime I open the music app and play music the DSP manager always crashes.

DSP manager
Hello, I just got a new fresh install. EVERYTHING wiped out, even sd card. I'm getting force closes when trying to play music. DSP Manager is not working as it should. Is this a known issue or only me? Thank you, this rom is great!

DSP error logcat
Hello, here's the logcat, not sure if well captured, it is my first time capturing logcats. Captured with CatLog.

3g not working and apn keeps unloging me from network, when disabled no probs except no internet... Any ideas?
E: switched wifi hotspot on and disabled adb and it worked...
E2: guess it is just usb debbuging, works fine with bouth off
E3: had some more weird issues then reinstalled rom and all works fine now. I love it, fast and stable. [emoji2]

Hi, i have got this rom for 2 weeks. At the beginning it was fast etc. Now it cant even kepp launcher in memory? When i want to open any app for few mins, then i wan to back to homescreen it is loading all apps and widgets.. Also i cant back to my apps which i used few seconds/minutes ago cuz it's loading like a new open. When i had viperx 4.2.2 it could keep uc browser and some pages for few weeks, and when i wanted to open, it took 1 second for me. Now im feeling like on my 1st galaxy spica.
Is that normal?
I'm using clean master and it does nothing.
I have to change rom or something?
Second Q, are videos in browsers woring ok for You? I have to restart HOX sometimes if i want to watch someting. And is there any solution to watch videos like on PC? I mean, my player is everywhere the same. It's annoying becouse, sometimes i have to change resolution but i cant, also i cant turn on full screen mode second time, i have to releod page, then watch it on full screen.
Thanks,

A noob in need of help here
Hi there,
I tried to install your latest version crdroid-5.0.2-20150121-endeavoru on my HTC One X but I got only an infinit HTC image. I am not very familiar with this things but I think I did what the instructions said:
- start on recovery mod (I am using TWRP v2.6.0.0, the one I used the only time I installed a custom rom);
- installed "crdroid-5.0.2-20150121-endeavoru" and "pa_gapps-stock-5.0.1-BETA12-20150116-signed" and did a data wipe in the end;
- reboot.
As I said, after restarting, I get the HTC start image and nothing progresses. Any idea what I am doing wrong (and how to make my phone back to work)?
Thanks a lot.

If you put the ROM zip on your PC and open the zip file (not unzip) you'll see a boot.IMG inside,extract the boot.IMG to your pc. I'm assuming you've got the fastboot controls on your PC.

No way no way to move app to sd in this rom?

Help me!!!
Hello, still no way to move app to SD, always tells me that is full and no space ...

HI
When a new version is offered ??

Thank you very much.

Fixes & futures possible?
Hellow everyone,
recently I've installed the ROM wich is a great build I must say. The experience is smooth and I haven't got any random reboots. But when I reboot the phone, it gets stuck on the HTC logo. After 3 reboots it will work normal again. Sometimes the WIFI doesn't work after a reboot and I have to reboot it again.
Not experienced anymore in build 20150210
Another problem I have is that the AdBlocker isn't working (I still have advertisements in apps) although I've downloaded the latest host files.
Still not working in build 20150210
Something that bugs me is the fact that I can't choose wich page of my homescreens is my home-homescreen.
Available in build 20150210
The last things that in my opinion are missing are a good (digital) clock widget and a simple mail client. In the original Sense ROMs the clock is fantastic and the mail client is just good. I'm now using K-9 mail, but I think there are too many opions in it. (suggestions?)
I installed the wrong Gapps
Probably some things are fixed in the newest build, but I can't find the changelog of it on XDA. It's there! And how do I update my ROM (I am used to OTA updaters, idea?)? Just dirty install the new ROM?
The answer is dirty flashing. (just install the ROM and clear cache and dalvik (I guess))
Beware, for the new storage layout read this post:
http://forum.xda-developers.com/htc-one-x/orig-development/storage-layout-hox-endeavoru-t3022358
In advance thanks for your work and answer!
Keep up the good work! This is the best experience I had so far with an AOSP (had CM, but didn't work that well).

releasenotes?
Hi!
Thanks for your great work on this rom.
Is there a list of changes from the previous release?

Enjoying this rom
Thank you team for a very good rom. I have an HTC One X [Endeavoro] and have experimented with many roms over time. I always fall back onto JB Sense 5 Blade Elite 2.0 with Lyapota mods flashed.
The CM KitKat roms just didn't tick all the boxes for me. Functionality v battery life.
But I am so impressed with this Rom, especially so early in the development.
With crdroid 5.0.2-20150210, I am running the native launcher with PA Gapps mini. Touch recovery 6.0.4.8 gave me a problem restoring the back up but after allowing root access in dev options (I don't know if that made a difference) and flashing twrp-recovery-hox-2.8.1.0 the twrp back up restored perfectly. The Rom is so smooth, battery life is great and everything works!
Congratulations team

If you hold your finger on the screen and the pages display, there is a small home icon at the top of your current home screen, just move it to the one you want, It works.

flashing it.. um... hope it not be auto looping in bootloader, i am using CWM + philZ to flash it.

Im looking forward to trying this rom.
Im just doing the last backups - ill report back later
---------- Post added at 08:29 PM ---------- Previous post was at 07:43 PM ----------
It took a longer time than normal to install - like OP said. But it did flash, and it did boot (after a while)
However, there are no data connection, and there are no keyboard.
Any idea how to solve that?
EDIT:
I solved the problem with the keyboard.
Settings -> Language & input - > current keyboard. Slide the "Hardware" option to on.
Still no data connection

Data not working?
Data is not working on my T-Mobile note 2 after installing rom. I will get 3G for about 1 second and then it will disappear. It comes back every few seconds and then disappears again.

hello ub team ...
Team UB can you develop the same ROM for n7100 with all your tweaks and can you integrate touchwiz from s5 lollipop Poland release available on sammobile..see what you can do sir

cm12 mobile data
hey guys i installed this rom on my n7105 last night and when i got to use mobile data the 3g icon just blinks one once then its gone it doesnt work.. any ideas?

So far ive concluded that i really like lollipop
However, this version is unfortunately too buggy for me.
There are no data connection - and i assume there is no solution to that, since OP havnt responded to it.
Using the "call button" in the text notification isnt working either.
The system profiles, does not trigger on connecting to WIFI networks.
Good job porting the rom - but it needs a bit of work yet imo

Everything works fine except the wifi reboot thing and the application not installed problem. But anyway i love using this rom so much, so thanks for your work

No problems with data?
Is it t0lte you have, or one of the phone from an US carrier? like at&t or something?

Happy to say its been about 15 hours since install and I haven't had any issues at all. Phone, data, SMS, cameras, updating apps, FB, xda, email (gmail, yahoo), etc are all working fine. No issues, FCs or RRs to report! Definitely has become my DD! Thanks to the devs who have took the time to keep our GN2s still a force to be reckoned with! :thumbup:

How About Recents Menu Slugginess?
I checked 17 December build of CM12 and Resurrection Remix. How about this ROM, and if you did, how did you manage to fix it?

Anyone Got trouble with forwarding and backwarding a video? Fwd en rew any video format results in a freeze But sound works good. I tried hw and sw decode

Has anyone had any trouble with Google play movies instantly crashing on open? All other video apps open fine. Tried reinstalling the app and clearing data. Currently running nightly from 26th.
Everything else is working perfectly including moto360 and chrome os trusted unlocking.

Issue when powered down and charging

So much thanks to OP for his help, but in not done complaining because I need to know if this truly is a perfect rom... There seems to be a faint green color that appears on my screen and at first I thought it was my phone but then I rebooted and it was normal again is this a bug or a bigger issue?

TBO Gapps
]I'm a bit confused. Do I install the TBO Gapps or install the recommended Gaps that was previously here for this update (5.1.1)? Also to update from 9.2 to 9.3 is it recommended that I wipe then install a fresh 9.3 rom or can it be flashed over?

Enjoying the latest 9.6 but having an issue with LTE .. using straight talk..

Hey I am completely noob at this I have been getting by with google and leaps of faith rn and I have a few questions that I couldn't find anywhere
But first may I say I love you so much My phone is a amazingly fast now and I am out of jelly bean now.:
1. Battery life- It is now realllly bad I have tried the calibrate thing that you are supposed to do but its some times so bad that when I put my charger and charge it still discharges and only goes back up after it hits 15% or so...This did not happen in jelly bean so just curious is there anything I can do ?
2.Boot time- It takes an awfully long time to boot and once it is booted 30 seconds later it goes back into showing Samsung logo and then 15 seconds of that it goes to the home screen
3.Optimizing apps- Every time I restart it says optimizing apps some times its 94 or times 12 or 46 idk what that is about or if that is supposed to happen
4.DU-updater - I am guessing this is how I am supposed to update. Not entirely sure how though I think I have to download it and then goto twrp and flash it there. not entirely sure...
5.Overheating- The top part of my phone is getting scary hot . I cant touch it for more than 45 seconds. I dont know why I have done everything like I am supposed to and everything else works...
6.OS- Where is it exactly ? Is it on my sd card ? I know I installed it from my sd card and I think it is installed it to the internal storage ... I am not exactly sure and I am scared to take out my sd card ... Also is it safe to move the backed up version of my phone onto my desktop to save space on my phone ?
7. Camera- I noticed that the camera software on my friends phone who were on the lolipop touchwiz camera was clearly much better as I was on jelly bean and I was wondering if the software I have for the camera is on the same level as theirs ? Sorry if it is a confusing question!
I am running a theme and nova launcher on top of the OS could this be a reason be a reason for any of these problems ?
But other than that everything works great and I love you so much man!!!!!! You are a genius. Sorry if I asked dumb questions this is the first time I have successfully done this !!!

Data not working
Hi there... I tried to use your ASOP rom but 3G data is not working for me... Do you need any details?

Dont know what could it be, personally data works for me fine.
If you can make logs when you enable data, will check them.

Which custom kernel work with this ROM?
How about daily performance with Rom stock kernel?
Sent from my Galaxy Nexus using Tapatalk

I am using stock kernel, batterylife and performance are more then good enought for me.
If you need more, you can use every kernel made for kitkat without any problems.

problem with fancy kernel
great rom but with fancy kernel r60, super su doesn't work (

I use stock kernel and that is enough for me, it gives best performance. And I just use trickestermod/synapse to change color properties.

Dont know why with fancy supersu does not work, with stock is all ok so far as i know.
Does not root it since last two updates, because dont need to root it anymore since its clean as possible and fast enougth.

Hello, your ROM is super fast and stable. But i have one problem, sometimes it is freezing, and i have to put out the battery and turn the phone again. I do not know where the problem is. I am using fancy kernel r60.

Some inconveniences.
Hi, I wan' to tell you about some bugs? or whatever it is. Sometimes when I want to turn on the mobile data, in settings, the screen sometimes flashes and I have to go back to the setting and again click on Mobile Data. Sometimes I have to repeat this many times. The second bug is in contacts book, there are some small squares on contact images in right bottom corner. What i have to do to get rid of these unpleasantness? I'm clean installing ROM and use franco kernel. Should I use your kernel? The ROM is great, super fast, and chrome is working as well as on my friend's note 3. Keep this very good work up.
Sorry for my bad english.

Having exactly the same problem although my Tab does not reboot but turns black (not 100% black, a very dim backlight still active). Doesn't do anything until I force shutdown by holding the power button.
Currently on nightly 21/04 CM 12.1 using Nova Launcher. But happened with 18/04 aswell.
Also tried RedKernel to fix the problem --> no change.

The gapps that I'm using actually replaces the stock launcher with Google's launcher. Maybe that is why I'm not having problems with the black screen anymore. I had the black screen also when I first installed 12.1 after a factory reset. The problem seems fixed now that the stock cm launcher is replaced with Google's launcher.

Does the rear/main camera finaly work with canogenmod?

Depends on which camera module you have.

problems with the firmware
I have constantly reboots plate during charging, and as you can not edit the name or avatar if not before that create what some other contact.
installation steps:
stock rom 4.2.2 -> cm 12.0 -> cm 12.1

You can edit the avatar from within the contacts application.
I would suggest a factory reset to see if that fixes the reboots while charging. I've also just posted gapps 5.1.1 in the Delta Gapps thread for cm 12.1.

Yesterday I installed the latest version. Within two hours twice I had a black screen while using Pocket. Today I did a clean install with Deltadroid gapps. I'll see what happens.

Black screen on LG v500 running CM 12.1
This post is related to "http://forum.xda-developers.com/lg-g-pad-83/development/rom-official-cyanogenmod-12-1-t3086899/page9" thread (but as I'm new in this forum, it does not allow me to post in that thread.
I'm using CM-12.1-20150509-NIGHTLY-v500, and I'm experiencing these "black screens".
For me, it usually happens when I'm typing something (no matter whether in Evernote, nor Inbox, nor posting a message in the Clash of Clans).
And the only way to regain the screen is rebooting the tablet.
I'm using the Swiftkey Keyboard (v5.2.2.124).
The oldest build I can recall that these black screens weren't happening is CM-12-20150304-NIGHTLY-v500. Perhaps this might give a hint on what to diff against.

Black screen cm12 v500
Got a blank screen issue with cm release of may 10th, using tweeter.

I think this has been a problem since cm 11. It seems like it happens randomly.
It seems that this is not an isolated v500 issue. The nexus 4 has the same problem because they both use the same video card.

As you don't say much about your system...I will say you will possibly get rid of the black screen freezing by loading this kernel: Rick Roll's #15 found here: https://www.androidfilehost.com/?w=files&flid=19557
Later versions of RR's seem to not 'fix' the issue, but this #15 has fixed it for me. For a bit of info, I'm running the nightlies (now on 2015-05-11 with RR's #15) So far, so good for me.
EDIT: all you need to do is boot to recovery and load the #15 zip and reboot system on TWRP.

I am running rick kernel 18 now. Will switch to 15 once I get a black screen...
Will let u know.

I tried again. Loaded the latest nightly, all works except for moving apps to SD . indicates there is not enough room. Went back to the Korean stock ROM and no issues. I love CM12.1 on my tab s and moving apps works just fine. Am I doing something wrong?

Thank you for ur reply. At first i running R18. But having black screen n freeze. Switch to R17 now. Having the same issue but not so many time compare to R18. Will try R15 and report.

Is the black screen issue fixed yet? I practically stopped using my GPad due to this issue. It happens to me very frequently and there's no rhyme nor reason to it. I may try other roms out, but I love this one so far except the crippling black screen.
