slightly offtopic, droid 4 with cm 12 lasted without charge more than 6 days (see the attachment), maybe it would last 7 but i charged hit at the mornong to flash with new rom
[Motorola Droid 4] joojoobee666:
So, I'm not quoting your whole post for obvious reasons. :) Anyhow, I bake my ringtones in to system/media/ringtones during build. And swithing those around works fine. So I created a new ringtone and saved to sdcard0 (which is my actually my external) and set is as the ringtone, then rebooted. It defaulted to some stupid chime (cobalt according to logs), even though the setting persisted. My current guess is that the sdcard is not mounted fast enough during boot, causing that file to be unavailable and the system reverting to a default. During an incoming phone call, the logs don't even show it trying to use the set ringtone so it must have failed long before. I logged the whole boot, I'll see if I can spot anything in there and let you all know.

Update: Didn't find anything yet, however I'm confused as to why everything blew up for you when playing around with the ringtones. I copied the new ringtone I created to the /system/media/ringtones and it worked just fine, even after a reboot. I used Root explorer to copy and didn't bother changing permissions. It was just a stereo ogg at 22,000hz, 16-bit. :eek:
[Motorola Droid 4] Septfox:
Because as it turns out, I'm an idiot. Or at the very least not thorough enough.

Since my old 2.2-based phone, I've been using Total Commander since it's 1: free, 2: small, and 3: has a dual-pane view. And it worked brilliantly upto and through KK.

Since it was updated in December, I automatically assumed it was made compatible with 5.0; and indeed, it seems to be. For basic file operations.

Using it (and probably a lot of other file browsers that haven't caught up) to copy ringtones into the system folders results in them not showing up. This is what sparked my messing with permissions, which in turn caused everything to blow up in my face.

Why? I have no idea. Maybe it's not remounting the file system properly and the file(s) get screwed up despite looking ok, maybe the media index doesn't get updated right (though, as I recall clearing it and letting it rebuild was one of the first things I tried before managing to break everything *shrugs*), no idea. It just doesn't work right.

Using the bundled File Browser to copy the files from the SD card into the system folder works fine, though the permissions still need to be set right (644, or Read for all and Write for owner) or they won't play. The Group should also probably be set to Root, but it didn't seem to matter.

I imagine that Root Explorer sets all this automatically, which would be why you had no problems.

So to summarize for people looking for a solution:

Copy ringtones to SD card

Use File Explorer/Root Explorer to copy the files to the system ringtone folder

If using File Explorer, then longpress on each file, open Properties, switch to Permissions, clear all checkboxes except the entire second column and the first box in the third column (resulting in -rw-r--r--). Also change the Group to Root, because why not

Enjoy, until Lollipop throws another fit

If you end up with doubled entries (due to checking the ringtone list with the premissions set wrong, then again after fixing them), go to Apps, find Media Storage, and clear its data. Reboot, give the phone time to rebuild the index, and all should be well.

edit: on a related note, if you use a utility to disable Media Storage as a startup item (not completely, that will break things), boot completion time is reduced by quite a bit, and the phone is ready for use sooner. This *shouldn't* hurt anything long as you use MTP to transfer music (it updates the index after each transfer iirc).
[Motorola Droid 4] jbeazell:
Hi All,

I previously tried the 1/22 build and had horrible experiences with severe system lag and bouts of 100% CPU utilization all over the place. It would happen for minutes at a time after unlock or after trying to open apps. I wasn't even able to get into CPU monitoring tools to see what was eating up all my system resources. By the time I was able to get into the monitor, the event had passed. I couldn't get into it before the event passed.

I completely wiped almost everything from both the internal SD card and my external SD card, which included a bunch of junk from a bunch of ROM flashes over the past few months. Also, about 12 GB of MP3's on the external SD card.

Well.... so far after the initial flash, things seem much better. I'm also using cool tools to see the CPU stuffs, and things are not pegging anywhere near as much as they were before. The spikes are occurring for events that I expect (EG: restoring apps with Titanium Backup, installing things from the Play Store, etc.).

I haven't tested the one problem, ringtones and notifications, yet. I previously tried copying things into /system/media, but got some permissions problems. I'll try again tonight. I don't have my personal sound files on there after the near-complete wipe :)

ALSO: does any body think that using MP3 ringtones/notification instead of OGG files is an issue? It's never been an issue before. Just curious.
[Motorola Droid 4] Septfox:
Shouldn't be. The "external" Ringtones folder is probably expected to be used for mp3s, what with people using songs as ringtones. The internal folder shouldn't be any different. So long as there's a codec available, I'd think that any file with an audio stream would work.

I just gave dropping an mp3 into the system folder a try; seems to have taken fine, the picker playback and volume previews are working as they should. Just use the File Manager to copy them in, set the permissions as above, and you should be good to go.
[Motorola Droid 4] jbeazell:
This flash seems to be much much better than any I've done before. I was able to move my audio files into the /system/media/audio/... folder and set the permissions correctly (as stated above, rw-r-r, and then they showed up after a reboot. My notifications now play, and seem to survive a reboot. The phone is running amazingly fast, even better than it was before. that's awesome.

thanks!!!

tried to update to the build of january 28th and now I have a mile "stone" -.- shows shortly the red motorola sign and then black screen.

why does an update remove safestrap!? I simply booted into recovery and then flashed the zip, cleared cache and installed mentors patch again.

Rebooted the phone and nothing is happening -.-

What can I do now? could someone please help me?
[Motorola Droid 4] joojoobee666:
Did you happen to flash to the stock slot? If so, if anything goes wrong there, safestrap no longer works. It requires a working rom on the stock slot since it needs access to all the files in /etc/kexec in order for kexec to function properly (since we dont have an unlocked bootloader :()....which safe strap now relies on. I personally still have the stock Moto JB 4.1 on the stock slot and refuse to touch it. I don't feel like SBFing again...ever. I'm not saying you cannot use it as there are benefits, but it comes with a risk.

If you need to SBF, [MENTION=4267571]sd_shadow[/MENTION] has a great collection of links here: https://docs.google.com/document/d/1zKJ22e26gDD54YXYRWZE5IlL71MJa6pXDJ_EshpLDUU/edit?pli=1

If you didn't flash to stock and this is still occurring, well you're most likely going to need to SBF again anyhow. I cannot say what went wrong but if you cannot get to recovery, you are SOL.

EDIT: I should mention, once again, that none of these CM12 roms are sanctioned/approved for use in stock as this is currently NOT being tested during development. It has worked for some but has failed miserably for others. Flashing to the stock slot is always risky, even more so when these are untested there.

For dummies please....

Hi there!

I have the latest CM11 installed to my phone along with Safestrap v.3.73.

Could someone help me and explain (for dummies please!) how to install Safestrap v.3.75 and CM12 to my phone?

Thanks a lot in advance and sorry for bothering... :)
[Motorola Droid 4] sd_shadow:
[MENTION=3457922]stargo[/MENTION] has released a updated safestrap (v3.75 - Jan 2015)

Cm12 requires safestrap v3.75 (or newer)

Safestrap-XXXXX-v3.75.apk (31-Jan-2015 )

if you installed the debugged version likely do not need to upgrade, but if you have 3.74 or lower use Safestrap-XXXXXX-v3.75.apk (or newer)

follow the readme.txt instructions on the download site

Download the version for your device

Droid 4 = maserati, Droid Razr = spyder...
[Motorola Droid 4] joojoobee666:
Check the first post on this thread for the safestrap link and the link to download the nightly (sd_shadow supplied direct link above). The safestrap link includes instructions for installing it. Also, the link to the CM12 nightlies download can be found there as well. Install safestrap FIRST and be sure you do this from the stock slot. As far as installing Cm12, nothing new. Boot to recovery and install to whichever slot you want.

I recommend NOT installing to the stock slot, you do so at your own risk (risk of needing to SBF if anything goes wrong). I believe upgrading from CM11 to CM12 SHOULD work, but I haven't tested it myself. I'd recommend a clean install anyhow, either to a new slot or wipe current slot. If you are doing this on stock slot and you choose to wipe, do NOT reboot until you have completed the ROM install (wipe or not, doesn't matter as you just don't want /system to be empty), otherwise you will be SBFing again.
[Motorola Droid 4] Sensonic:
Yeah, I read it but I don't understand these ones:

* Uninstall Recovery

* Uninstall the Safestrap APP (due to the different key)

* Install the new Safestrap-version (signed with a new key)

So I will switch my phone on, boot to Safestrap (with the stock ROM active). What then? How do I uninstall recovery from Safestrap menu and how do I uninstall the old Safestrap version? That's something I don't understand because I haven't used my Droid 4 for a while (used my Lumia 930 instead).
[Motorola Droid 4] X_Files:
Boot to stock rom. Open the old Safestrap app. Uninstall recovery (button in app). Uninstall the Safestrap app (settings->app). Install the new Safestrap 3.75 app. Install recovery. Reboot. You should delete old rom slots and create new via new recovery.

hey there!

It seems that i can't run an ussd code on that CM12 05.02.2015. I have typed the code, then pressed call button and my droid called *107# rotfl. It works like a charm on CM11. Moreover this lollipop is supposed to be faster than kitkat, but its very choppy on my droid.. Good work guys, but its a bit too early to make it official imo.

i'm about to restore my kitkat.

cheers! :)
[Motorola Droid 4] Sensonic:
OK, got it! Thanks a lot to everybody involved! :)

Couple of questions:

1) The weather center (on the front screen of CM11) seems to be missing from this CM12. How to restore it???

2) Where to find Droid 4 (Maserati) suitable 2015 Gapps apk? The links (on the first page of this thread) don't seem to work :(

3) Does micro HDMI port work with this CM12?
[Motorola Droid 4] sd_shadow:

[Motorola Droid 4] Sensonic:
Thanks a lot!

Still I'd like to ask four (silly) questions:

1) How do I change the themes in CM12? I'd like to place my own photo on the screen but I didn't find the option for it. In CM11 there was that kinda option.

2) How to get that Yahoo Weather on the locking screen like it was in CM11?

3) I flashed Mentors GSM patch to my phone. 3G is now working but the signal strength doesn't seem to change anyhow. It's always in the middle of the signal meter What gives?

4) The most stupid question: I had CM11 in my phone, wiped it off and installed CM12 to ROM slot 1. Do I have to root the phone again or does it stay rooted?
[Motorola Droid 4] Septfox:
This was actually in some of the earlier builds (the lockscreen used the CM cLock widget, as I imagine CM11 does), but was changed back to the stock clock for whatever reason.

From what I've read, though, they were planning on changing it back to using cLock. I don't know, I'm still on a build from 1/28. To see if they've switched it back, add the cLock widget to your homescreen and configure it to display weather; the changes should apply on the lockscreen if they switched it. You can remove the widget from your homescreen after it's configured.

If it doesn't come up, well, I suppose it'll be added back in a future nightly.

Rooting is a per-ROM thing. So no, it doesn't stay rooted.

That said, CM12 currently includes root access, configured in Developer options. No need to mess around with flashing additional zips or anything.

[Motorola Droid 4] Sensonic:
An issue I've with CM12: the video of micro HDMI port works but the audio doesn't. Any possibility to fix it ASAP???
[Motorola Droid 4] Oggie7797:
Depending on your setup, use an auxiliary cable to plug into headphone jack. On my laptop I do that because hdmi audio is buggy on ubuntu so I just plug it directly to surround sound.
[Motorola Droid 4] Sensonic:
OK, thanks for the advice!

But I must say that this lack of micro HDMI audio is a real "deal-breaker" for me. Fortunately I still have the backup of my KitKat (CM11) setup so in case it won't start to work with CM12, I can revert back to CM11.
[Motorola Droid 4] joojoobee666:
Did you install the GSM patch from the first post? If so, I suggest resetting the APN's back to default to see if that helps.

As far as the other apps crashing, I have not had either of those issues. Does it happen on a clean slot? If not, I suggest wiping the data for those apps to see if the issue persists

Performance Tweaks

I've done a bit of digging and I've found that one of the primary reasons our performance is choppy is that the eMMC device is very slow when used via loopback.

Slow storage is slow, but these sysctls can help. I've avoided "sysctl vudu" and explained what they do and why I've chosen to modify them.

We don't want to swap applications out if we can help it.
Prioritize applications over data and just generally try to
avoid swapping unless we really need to.
--
vm.swappiness=10

Reduce vfs cache pressure. This allows dentries/inodes to
take priority in the cache over the block cache. Android does
a lot of stat(), open() etc pretty much any time you touch the
screen so this tweak helps a lot.
--
vm.vfs_cache_pressure=20

Start writing dirty blocks(cached writes) sooner rather than later,
but allow up to 40% of available cache memory to be used before
making the application wait. This works well for bursty usage such
as web browser cache writes.
--
vm.dirty_background_ratio=5
vm.dirty_ratio=40

Purge unused objects a little slower. This is the only one I would
consider supersitious vudu. It *seems* to help but I couldn't tell
you exactly why.
--
vm.min_free_order_shift=3

I'm trying to get sysdig working on my device so I can further analyze performance issues. Has anyone had any luck with this?
[Motorola Droid 4] Sensonic:
I found two more "bugs":

1) my phone doesn't recognize 64Gb SD card (with CM12) which worked just well with CM11.

2) Folder Mount app doesn't work. It starts to examine whether the phone is rooted and won't go on.

Any hints how to get those ones to work???

GSM problems

Hello,

I'm having trouble with the calls on my Droid 4. I'm on a GSM network in Romania called DIGI but also have a Vodafone SIM and I'm using Mentor's patch v 3.3.1 on the latest Cyanogen nightly cm-12-20150212-NIGHTLY-maserati.zip.

The problem I'm having is that sometimes when someone calls me the caller gets a calling tone but my phone doesn't ring. I don't even get an SMS about a missed call. The strange thing is that the problem only happens sometimes. This also happens on CM11.
