Update

Changelog update 18-12-2014:

- device name changed from cdma_maserati to umts_maserati

- tried to improve the signal strength

- tried to improve the 2g/3g switching

- tried to solve the problem that the stock rom has with some router wifi

The feedbacks are needed specially for the last point, i do not have one of that routers that has problems with this phone so i can't test personally.
[Motorola Droid 4] FN86:
Solved.

Changelog update 19-12-2014:

- optimized the debloating phase during the installation
[Motorola Droid 4] FN86:
Mentor.37,

Thank you for your wonderful ROM patch and continuos support!

If I come to USA and want to use Verizon, should I flash stock firmware image, or it would be enough to adjust network type in service menu?
[Motorola Droid 4] Mentor.37:
In this rom i totally removed the support to the cdma network so if you have to use this phone in the US with a Verizon sim you can't use this rom.
[Motorola Droid 4] KwiHa:
Hi,

Thanks for your job and updates. :)

Do we know which wifi routers had/have connection issues?
[Motorola Droid 4] Mentor.37:
The stock rom has problems with routers 802.11ac that work at 5GHz, with my last update i think that i solved this problem but i'm not sure because i do not have a router wifi 5g and for this i need some feedback.
[Motorola Droid 4] KwiHa:
I have a Virgin Superhub (Netgear VMDG490) with 5G option.

My Note3 can see the 5G network.

Droid4 do not see the 5G but it's working fine on normal WiFi band.
[Motorola Droid 4] Mentor.37:
Really important update

Changelog update 01-01-2015:

- the rom is now only compatible with the version 9.8.2O-72_VZW-18-8 that you can install with this utility

- I totally rewrote the build.prop

- I installed in the rom the support for the Fast Dormancy

- The rom is now totally GSM\UMTS oriented

- I added the toggles widgets in status bar

- I optimized the data and i added in the status bar the icon that indicates when the data are off

ATTENTION: now the version for JB automatically performs a factory reset at first install.

ATTENTION 2: if you installed the Mentor's Rom released the 18/12/2014 then this update will have a problem with the factory reset and for this you have to manually performs the factory reset.

Happy new year to all.
[Motorola Droid 4] Mentor.37:
Was you able to connect to it also before the update of the 18-12-2014 ?
[Motorola Droid 4] KwiHa:
HI,

I do not remember I've ever seen or not the 5G option on Droid4.

But there is a strange thing:

After the wifi connection the the wifi bars shows a weak signal (close to router as well), connection also slow and 1 or 2 minutes later the signal jump up to normal and all going well.

I'll test it with the new update on the weekend....
[Motorola Droid 4] Mentor.37:
New update, probably the latest.

I just published a new update to fix the freezing during the installation of some app introduced in the previous update and in this version i had to remove the fast dormancy and the modded statusbar.

Unfortunately after this update you have to do a factory rest.

Because there isn't enough interest i decided to stop the development of this rom, almost surely this is the latest update.
[Motorola Droid 4] wapsi:
Thanks for your excellent work! This ROM/patch set has been very good.

BTW: I've experienced situations where suspend_backoff is keeping my device awake all the time. I've investigated the problem using BetterBatteryStats, WakelockDetector etc. but there isn't any specific application that is causing those wakelocks. I've tried to uninstall ~everything but suspend_backoff is still there. "Android OS" is the most battery consuming application listed in battery stats. The only way to get rid of this is turning the power off and rebooting the whole device. Then it could take couple of hours or couple of days and the problem comes back. Have you faced this kind of problem? I'm using my phone in Finland (operator: Elisa, GSM+UMTS).
[Motorola Droid 4] Mentor.37:
Probably you are using the 01/01/2015 build, right? That build was really experimental and much instable.

You have to use the latest build, 07/01/2015.

If you installed the 01/01/2015 before installing the 07/01/2015 build you have to reinstall the main system 9.8.2O-72_VZW-18-8.
[Motorola Droid 4] Mentor.37:
Well, i will investigate this week-end, meanwhile could you try using a clean system without third part apps installed?

I do not have this problem but in my personal build i have totally removed any google app, if you want you can remove any gapps with the patch linked in the main thread.

#Postedit:

After some test i do not have notified any anomalous wakelock.
[Motorola Droid 4] KwiHa:
HI Mentor,

Thanks for the updates.

If this is the latest update, could you please prepare a version without that roaming pop-up screen? It's cause a lot of problem for me... :(

Many thanks!
[Motorola Droid 4] Mentor.37:
You can try the 12-01-2015 update.
[Motorola Droid 4] FN86:
Hello, Mentor.37,

Are there any problems with latest version of your ROM, that require fixing/further development?

Also, out of curiosity, do you still use Droid4 as your main phone?

Yours sincerely
[Motorola Droid 4] Mentor.37:
No, in the rom there isn't never been any problem, i continuously updated the rom to optimize ever more the gsm and the battery drain but now i'm at a point where i can't do much more so i think that I will not release a new update.

The Droid 4 is still my main phone because i need a phone with a good physical keyboard and for now the only solutions are the Droid 4 and the Photon Q.
[Motorola Droid 4] Mentor.37:
There is a new update dated 23/01/2015.
[Motorola Droid 4] GavTheStoner:
Thanks for the update mentor!

The charging LED does not seem to work for me in the latest (23/1/2015) version though. Have tried factory reset and reinstalling it with no effect.

This is on a freshly installed 18-8 version of the stock rom.

EDIT:

Hmm, it just was not charging from my PC's USB port but charges fine from the wall socket and light works there.

Weirdly, now it will not charge at all from the computers USB ports (tried front and back just in case). It did before...

EDIT 2:

Reinstalled motorola driver and restarted the computer, works now.

Thanks again for the rom mentor!
[Motorola Droid 4] KwiHa:
Toggles

Hi Mentor,

It's a great ROM as usual. :)

Do we have any way to rearrange the toggle bar and add/remove icons?

Thanks
[Motorola Droid 4] Mentor.37:
No, I'm sorry.
[Motorola Droid 4] saljut7:
Hey Mentor, just noticed your interesting Rom which I would like to try. There is one thing I couldn't figure out: I don't like preinstalled Google Apps (so the whole package containing Play Store, gMaps, gMail and what ever no one knows). At the moment I'm running Cyanogen because it comes without Gapps (using F-Droid instead) but there is a problem with the HDMI-output and I would like to use the Lapdock 100 with the Droid4.

So my question: Is there a Mentor's Rom without preinstalled Gapps?
[Motorola Droid 4] ferviverus:

[Motorola Droid 4] Mentor.37:
You can use this patch that will remove every Gapps except the Play Store.
[Motorola Droid 4] saljut7:
Thanks both, ferviverus and Mentor, for your replies!

Well, my privacy-paranoia balances between "Android OK" and "GApps not okay" (I know this opinion is debatable but setting personal privacy-paranoia is always subjective).

And there is no way to remove PlayStore as well?
[Motorola Droid 4] saljut7:
This rom is for the xt894!?

I wanted to try mentors_rom_maserati_jb_gsm_multilocale recently but had a problem flashing the ROM.

This rom is for the xt894!
This rom is for the 9.8.2O-72_VZW-18-8!

I tried to flash the ROM slot which is still occupied by the stock rom because I didn't want to delete my working system. Unfortunately I have only enough space for one slot in safestrap next to stock rom.

Where did I make a mistake?
[Motorola Droid 4] Mentor.37:
This rom's update can be installed only on the version 9.8.2O-72_VZW-18-8 of the stock rom.
[Motorola Droid 4] saljut7:
downgrade?

So if the "Build number" of my stock rom is 9.8.20-72_VZW-18-9 I have to downgrade first using the linked tool?

(In addition to this I wanted to ask: In case your free rom works fine so far on my phone would it be possible to

buy

a version completely without gapps?)
[Motorola Droid 4] Mentor.37:
You can downgrade from 9.8.20-72_VZW-18-9 to 9.8.20-72_VZW-18-8 without any problem.

In the main thread you can find a patch to remove every gapp except the play store, if you are not logged in it then it will be as if it is not installed.
[Motorola Droid 4] FN86:
Mentor.37,

I installed your patch to remove Google Apps. The problem is, despite I have my google account set and gmail working, all my contacts, synced with gmail account, disappeared, there is no option to sync contacts and google profile, thus no option to add contacts from google profile in Contacts app. How do I fix it?

p.s. google contacts is the only missing function after the patch, I do not need any other google crap, thus would rather sync manually than reinstall the stock ROM. An option to add/restore automatic contact sync would be greatly appreciated though.
[Motorola Droid 4] Mentor.37:
You should solve your problem restoring the only app GoogleContactsSyncAdapter.apk in /system/app with permissions 644.
[Motorola Droid 4] saljut7:
confirmation?

Sorry I just want to confirm because stuff like this is not so common for me:

I apply this update-script ([SCRIPT] DROID 4 Utility XT894 Jellybean -- Windows + Mac + Linux (All In One!)) to downgrade my stock-rom fitting for mentor's mod?
[Motorola Droid 4] sd_shadow:
Yes that should work fine.
[Motorola Droid 4] saljut7:
Hi Mentor,

I tried to follow your instruction to downgrade my stock rom with the link you pointed on. LuH told me that this script is outdated and I should use the one of the OP.

Well, before I go on asking him (mattlgroff) if his script is working to downgrade my xt894 to the right version I wanted to ask you: Does Mentor's Mod will provide functionalty the HDMI-output for using the Lapdock 100 (using the Lapdock 100 was my original reason to try your mod because HDMI is not working with the lates stable of CM-maserati)?
[Motorola Droid 4] Mentor.37:
That utility is updated and it will install the stock rom 9.8.2O-72_VZW-18-8, you can download it from here.

With this rom everything works correctly without problems including HDMI, Webtop and Lapdock support, you can use the Lapdock 100 without problems.
[Motorola Droid 4] saljut7:
first step successfull

Hey Mentor,

thank you for confirming. Today I tried the downgrade with the quoted script and everything worked well so far. I tried to use Safestrap 3.75 as you advised in your first post but was a little bit confused what to do. The linked utility provided installing Safestrap 3.73 which was a little bit newer than my version which was already installed for CM (3.71). So I've used Safestrap 3.73 and installed JB and the debloater in "batch mode". Your JB Release started well and the Lapdock 100 works fine. :highfive: I hope it is okay this way.

Just two questions left:

1. I was a little bit confused by option [1] (install and wipe data) and [2] (install and no data wipe) of the utility so I chose [2] but I'm still curious: Which data would be deleted using option1? Just the data of the activated stock rom or all data on all physical attached memory (the explanation is a little bit unspecific for me)?

It would be interesting because at the moment all data of the so called "internal sd-card" (the not removeable one) is quite used by Apps and Settings I've installed by CM in Rom Slot 1. I think I don't need CM anymore (because of the missing Lapdock function). I didn't know that all Rom Slots share this "internal sd-card".

So if I want an "unused" internal sd-card should I restart the procedure wiping the data by utility option 1 ("Flash Official Jellybean Firmware (Wipe Data)")?

2. There is a small mod providing "better" settings for german keyboard layout (äöü and so ). I used this mod for my CM installation last time. Do you think it is okay to install it in addition to your debloater on Mento's Mod?

Thanks alot alot alot. The Droid feels like a Droid now! :cowboy:
[Motorola Droid 4] Mentor.37:
Safestrap 3.73 has a bug that causes problems with the hotspot wifi.

Safestrap 3.75 that i advised in the first post works like a standard Safestrap and you do not have to do nothing, the only thing that is a bit complicated is to install an aosp rom in the new safe slot that i provided in it, but this is not the case. Considering that in it i removed the startup splashscreen to access in recovery you have to select BP Tools in the Boot Mode Selection Menu as explained in my safestrap's thread and here.

About your questions we are a lot offtopic, anyway:

1) Option 1 only formats the partition /userdata, practically it works like a factory reset.

Option 2 only installs the stock rom.

Using the rom slots Safestrap creates its virtual slots in the internal sdcard using a lot of space, you can delete these slots from safestrap.

2) That mod could make this rom instable.
[Motorola Droid 4] saljut7:
Thanks alot. I understand but following [RECOVERY]Safestrap 3.75 for unused partitions: Where is the download for Safestrap? :confused:

I can see only one link for Ramdisk for cm11, cm12 and cm12.1. I have to ask this because I always installed Safestrap using some command line utility.

Thanks for explaining. In noticed I have only a superficial idea of the file structure of custom roms. The Dev of the mentioned mod confirmed problems applying both Mods yours and his at the same time. He said I have to patch your mod with his keyboard layout if I want to use his setting (which provides an "ä" by pressing "caps lock + a" for example) in your mod. But this will be another project, first I want to figure out how the safestrap-update works.

How to install Safestrap, there is even a video:

http://xdaforums.com/droid-4/general/index-motorola-droid-4-development-t2817578

You should do some research before making again a question that has been given several times a response.

This time I answered because you were not the first to have difficulty with the download tab in my Safestrap thread and I understand that it can create confusion, for this I put a direct link in it and I wrote in more detail.
[Motorola Droid 4] saljut7:
I was just blind to recognize the Download Tab. I'm sorry (but of course I did research... maybe not enough but I'm always happy not to push threads)!

So double thanks for providing the information another time. Everything went well and I decided to purchase the multilanguage version which has nice bonus features. Everything worked fine with installation and it is fantastic to finally use data encryption encryption feature with a Custom ROM and the Lapdock 100. :highfive:

There are two things I recognized after two days of using the new Mentor's Mod Multilanguage:

1. GPS-Symbol appears using OsmAnd but it can not find the position. But GPS didn't work under CM 10.2.1 as well so I don't know: Is this a general problem in custom ROMs?

2. The camera flash doesn't work anymore (was working under CM). Should I install Cyanogen in another slot to test if it is a problem with Mentor's Mod / my hardware - or is this a known problem (which I didn't recognize again)?
[Motorola Droid 4] Mentor.37:
In this rom

everything works

, including the GPS and the camera flash, for your problems you should consider an hardware failure.
[Motorola Droid 4] saljut7:
Actually I just noticed that the Flash works. My mistake was that I expected that the Flash turns on immediately switching to "Flash ON" in camera app. Beside this two of the flash light apps provided in F-Droid I tried just doesn't work (both called "Flashlight"). The third one I just now tried works well ("Search Light"). So I'm sorry... I just didn't expect that I have to try 3 different (and very simple) apps.

GPS: Maybe related to too restrictive AFWall settings? Will try it again when I'm outside with totally opened firewall settings.
[Motorola Droid 4] saljut7:
I tried again locating via GPS using OsmAnd~ - everything works fine as you said - it just took a while (about 1min) to get a location on the map.

I noticed there are two apps listed for updates in F-Droid. It is Superuser and µg UnifiedNlp for GAPPS-free devices (legacy).

Trying to update both I get an error "The new version is signed with a different key to the old one. [...]" uninstalling both quits with "(De)-Installation Error".

I remember a similar problem with updating Terminal Emulator in CM. Is it a proper way just deleting the apk from /system/app and then install the new versions via F-Droid?
[Motorola Droid 4] Mentor.37:
Uninstall a system app to update it is never the proper way to proceed, usually an app is signed always with the same signature to avoid this problem, if the signatures are different probably the update has been edited from someone who is not the original author that can re-sign the app with the same signature.
[Motorola Droid 4] saljut7:
Maybe it is possible that a dev uses different keys for signing the same app in Play Store and F-Droid? Both Apps were pre-installed in your mod. I can neither uninstall nor update them. So should just leave them as they are?
[Motorola Droid 4] Mentor.37:
Yes this is possible but it is improbable because usually any dev signs always his apps with the same private key.

Anyway i do not advise you to update your system apps from a different store if you are not sure that the new update is compatible with your device, you should use these stores to install and update only the user apps.

In this case the store that you are using would update Superuser and (if i correctly understood) NetworkLocation.

Superuser is the app that has been installed when you rooted the phone and for which there is for sure a compatible update.

NeworkLocation from some time is not more part of AOSP project and it is the only gapp that i was not been able to remove because Motorola uses it for some service and it is normal that can't be updated with µg UnifiedNlp that is an open source software for the geolocating.

Honestly i did not know µg UnifiedNlp, in the next day i will try to integrate it in the patch to remove the gapps.

#Postedit

I tested µg UnifiedNlp and it is not compatible with our stock rom.
[Motorola Droid 4] saljut7:
Thanks alot for your reply Mentor!

Well, but I never used another Store than F-Droid.

Right.

I've rooted the Droid4 with the tool you linked me.

So I think it uses an App which is usually updates via Play Store.

The question is why F-Droid offers me an update then when it is, as you say, normal that it can not be updated.

Thank you for testing.

In the end the update procedure is not the problem. The problem is that Android doesn't me allow to uninstall the programs and quits with an "(De-)Installation Error" so that I can not do anything.

[Motorola Droid 4] Mentor.37:
This isn't correct.

This rom uses the stock kernel so it doesn't needs safestrap to boot, safestrap only is needed to boot roms that use a kexec-ed kernel.

If you want you can unroot the phone and uninstall safestrap but you can leave them without problems. This only is a your choice.

I ask a question like that rom has better battery life, this stock rom modified or 4.4 CM11. Thank you.
[Motorola Droid 4] Mentor.37:
Surely this rom, this is the only rom for the xt894 that supports the fast dormancy for the gsm network.

I have both installed, this rom in the stock rom slot and the cm11 in the safe rom slot and with this rom the battery life is at least up to two days instead with the cm11 usually i have to charge the phone every 12 hours. For this reason this rom is my daily rom.

I took these screenshots just now.
