If the developer said he is not interested in bug reports of a version he didn't officially release just respect it. Wait until he actually releases something stable and that he's happy releasing and then you can report whatever you find.

I still disagree. If there are any bugs, the developers should know in case they have not been fixed. Don't you think?

the 9th oct build was not meant to be public and they posted that build with a warning - just for the impatient users - the flashaholics, they very probably know about all of these bugs so not needed to post it here and probably they will refuse to read such input - you still have the august build as the last official - post bugs from that build

@AntaresOne It seems that the rom has issues with playing .aac files, in this case whatsapp voice notes.
On whatsapp it crashes about 2 seconds before the voice note ends and the same using a music player (in this case I got this error that I've neven seen)
The files aren't corrupted, they all work fine on my pc.

I could provide logs, but I don't think you're interested in them as I use xposed, but this also happens without xposed, it exsists since I think one of the first builds (I can not remember)

Take your time! If it really is the last build before you start working on Android 6 it has to be free of all bugs that affect every day use.
And please, @smeroni68 , do not kill Mattia or anyone in JDC team, your work is awesome. [emoji106]

He can't kill me, I am way too far away!! Lol
I disagree. Bugs should be mentioned in case they have not been fixed since the October 9th build. Don't you want the next release to be bug-free?

When the link was posted to the Oct 9 build it was clearly stated it is a test build and not to report bugs. Flash at your own risk. When the builds are worked on internally we have a defined set of conditions to go by. It makes it more simple to find and fix bugs with the ROM itself.

Other things that are proven and known to cause issues are some Gapps packages (especially older ones), third party apps (such as Xposed), and anything that modifies system files. It has also been requested that if you modify any system files not to report bugs. You modified a system file, the team cannot fix that. These things are all beyond the control of the team and some are impossible to guard against.

As for Gapps packages, yes you can use one of your choice. We only suggest the open micro because that is the one everyone uses to test with. There are too many versions out there and to test for several days with each one would slow development so badly updates would never come.

As for flashing, many times a dirty flash will do just fine. Sometimes a clean flash may be recommended (but not required). When it is there are valid reasons. Sometimes a major code change would and dirty flashing could run the risk of an issue because of some "leftover" item that would be otherwise recreated after a clean flash. If clean flashing was recommended and you didn't, that is not the team's fault.

Another item to note is STweaks. It modifies system files, if you have tweaked undo them first and go from there. Things like undervolting and such can wreak havoc.

For many bugs one must start with only the ROM and see how it behaves, then start installing apps and testing one at a time. It can be very time consuming and frustrating. Even more so once you consider not everyone uses the same apps or combination of apps. Some app creators do excellent work and the apps they create are awesome and trouble free, while others are not.

One such example is an issue I had with the August 17 build and the Oct 9 test build. The battery drain was horrible. Previously I easily could go an average of 18-20 hours with normal to above normal usage, it dropped to 8-9 max under the same conditions. Using BBS and the one app at a time method it turned out that Avast updated the anti theft app and broke something in it. Once I removed it I was back to 20 hours battery plus. On lighter times I can get 36 hours plus easily.

In short, we are only human and do strive to do our best. Beyond that please be patient with the team. This is done for YOU for Free. If you want to donate it is always welcomed with a big THANKS and and open heart. But it is never required.

Oh man, I certainly cannot wait for a new build. My phone's barely usable these days (probably my fault from many misc tweaks etc!). I just had a couple of questions ahead of a new version / fresh rebuild:

- With the Mini/Pico GApps recommended - does this mean that more of the "standard" GApps that many users install, that aren't in these small packages, go into the User partition rather than System? Result being that the System partition sits there gloating with lots of free space, while the User area gets full even quicker? Due to lack of space, I've moved a lot of apps to SD (built-in functionality, nothing fancy) and I'm sure this doesn't help with strange problems...

- Second question relates to my major issue at the moment. I've not captured logs for this yet but wondering if anyone has seen this / might know a possible reason: it seems that when the phone switches from WiFi onto Mobile Data (and vice-versa) the whole phone comes to standstill for some amount of minutes. Unresponsive screen/UI, Spotify glitches/stops etc. Pretty much makes the phone useless when I'm on the go! Am on the latest I9505XXUHOH2 Radio/Bootloader since 5-6 weeks ago, and have possibly had the issue for almost that long (been too busy to really diagnose). Could this be related, or something else?

Have been desperately waiting for an acceptable Flagship phone to be released by someone (> 1080p, Wireless charging, Android Pay, USB-C, decent size battery, > 32GB storage+SD or > 64GB internal, OK-to-Good camera, not too phablet-sizey), but after the disappointment of the Nexus 6P release (can't believe Google let that ugly thing come out with their name) I've gone for an interim solution with a Pre-order for the Sony Z5 Premium. Now just counting down until then by nursing this beaten up old 9505 along... One more Clean Flash left in me I think...

Gapps normally go to /system regardless of install method. Unless I am mistaken the general thought is the install script in the package is where things get screwy. The important parts are in the smaller packages and I just update/install all apps from Google Play.

Not sure about your WiFi/data issue but I know at least some have been addressed for the next build.

I would have, but I've been holding on with the lure of a new "Optimised" version for a while :) My luck over the last year with this ROM (5.0 and 5.1) has been that a new build comes out just after I do a clean flash!

I feel like after a month or so on the ROM my performance dips considerably. Speed and responsiveness stay the same, but bugs start creeping out. This time, over the past few days, I've started noticing a lot of data/WiFi related issues. Typically this is fixed by toggling airplane mode or rebooting my device once or twice. However, more recently it seems that when WiFi or data starts acting up I actually get logged out of any app that I have open at the time. It's strange, but there's definitely a sense of entropy for me with every iteration of this ROM.

Call a terminal and issue:

Code:
su -c fstrim -v /cache && fstrim -v /data

You're correct about installing any GApps that weren't in the zip file. These are installed as regular apps and go into /data rather than /system.

Installing these apps into /system doesn't necessarily mean that you're saving space on /data, however. Any app updates get downloaded to /data, and live there in addition to the older copy in /system. The only way around this is to move the update to /system, or to install a newer GApps package.

^up and everyone else here:
I'm preparing the build environment to build a new public release, this one will include a lot of changes and it's the biggest update ever, clean installation is not mandatory but strongly adviced. If you get errors which should not be inside please make a clean install before reporting, thank you for the collaboration

I was one of the original Oct. 9th testers, and unfortunately I did encounter a few problems after using the build for a few days. I got a random freeze 2 times (one opening the Steam app loading content, and another when I got out of an app, I forgot which one), I got a stuttering audio issue, although with only one song, and that's pretty much it from what I remember.

Although this is a test build, so all of it will most likely be fixed when AntaresOne releases the final version of the build!

    • STweaks shows "no kernel support", what to do? Go in Developer options and enable root.

    Using F2FS
    What it is? Wikipedia

    To use it you should first convert your EXT4 partitions through recovery, before installing this ROM.


    On PhilZ:
    1. Wipe and format options->custom format options->toggle ext4 f2fs migration
    2. Format cache->f2fs
    3. Format data and data/media-> f2fs (Warning: internal storage is formatted, make a backup of your personal data before doing this!)

    On TWRP:
    1. Download and install this TWRP version: https://www.androidfilehost.com/?fid=24269982086988952
    2. Wipe->advanced wipe
    3. Select cache->change or repair file system->f2fs
    4. Select data->change or repair file system->f2fs (Warning: internal storage is formatted, make a backup of your personal data before doing this!)

    Now you can install this ROM following installation steps in post above

    Updates down the road!

    Hi guys :)

    Thread is back and cleaned, thanks to @malybru

    I don't know if someone had a look in my GitHub, I didn't stop to develop anything :)

    I own a new build server thanks to @gkkovacs' kindness, pending request for another one by @azuziel :)

    With two build systems we may work way better, there's a lot of greatness for this device down the road!

    Already built a new update with MANY changes inside, currently being tested by other JDCTeam friends. Also sent download link to some Sprint guys to test data connection: @ccuchulain @mikshephard @mwilder817 @sekinger @todivefor

    Oh, almost forgot :p :p

    I'm glad to present the Jflte Developers Connection Team, in short JDCTeam!!!!!!!

    We are:

    • @alucard_24 ("I want AOSP fully working" mainly kernel developer, tester)
    • @angelcalibur ("I want your build script, Mattia", trainee ROM developer, tester)
    • @AntaresOne ("This is going to work...", mainly ROM developer, JDC GitHub repos maintainer, little tester)
    • @-+BB+- ( "I love Slackware", trainee ROM developer, tester)
    • @franzyroy ("Mattia update Dark Side theme on the Play Store", tester)
    • @Jimsilver73 ("I want Slim lockscreen shortcuts in Optimized CM", tester)
    • @Kryten2k35 ("Use OTA Updates, fast, free, many features, stable! ;)", mainly ROM developer, tester)
    • @smeroni68 ("Mattia, ETA??????", the brain, JDC founder, designer, tester)
    • A secret insider :cool:

    Hahaha :)

    Going to change this ROM to JDCTeam in the next update, time to let guys test and I will release, so it's very close!!!

    Also, any our project starting from now will be JDCTeam's own, except individual ones.

    In case anyone wants to follow our progress, you can see our GitHub: https://github.com/JDCTeam that for now is almost empty, we have to merge all our sources there :)

    We'll soon have our webpage, Facebook page and Google+ community!

    Things to download will be in RomHut, so not anymore in AndroidFileHost

    A huge "thank you so much" again to all the donators who donated to support this awesome project!!!

    With all your efforts, there are until now:

    • 125 total donations
      [*]879,30 euro!!!!!!!!!!!!!!!!!!!

    You're under "Credits" in 1st post as "Donators" :)

    Pretty good for a nice build system, but I will wait more :) I want to make a rocket like the old one, it used to build updates in only 20 minutes!!

    Now, let's start again guys!! :good:

    Clean install is strongly suggested, especially if you are on 17/08 build.

    If you use OpenGApps please reflash the GApps package after you update* the ROM (*but take care of the words rightly above this sentence)

    Random reboots? Take a copy of the last_kmsg located at /proc (you need a root file browser or terminal emulator [su -C cat /proc/last_kmsg > /sdcard/last_kmsg.log]) we need logs!

    Still bluetooth issues? Flash this and test, then let us know

    eMMC will be trimmed automatically at each boot, note that this could slowdown a bit the boot process but will prevent the ROM from being sluggish time over time. A log for trim is saved in /cache/trim.log, most of the times about /system will show 0 bytes trimmed: this is not a bug as this partition doesn't need trim at all, but has been included anyway.

    IR apps issues? No more a fear, just go in Toolbox->IR Driver!

    Personalize the notification LED at boot with Toolbox!
