Just to chime in here:

On CM /pds is never your original "pds"-partition but a backup-copy made at the last time you booted after wiping data. This makes sure that CM never modifies files in the original partition which could break things (like is happening here). If /pds is empty, this means that some other ROM (custom or stock, but that's unlikely) deleted the content of this partition.

The partition also includes stuff like camera calibration data, device-specific DRM keys and battery calibration data, which is specific to each device and is _not_ restored when returning back to stock by rds lite or fastboot!

If you have the file /pds/wifi/nvs_map.bin but got the generic mac after flashing CM, try just reflashing the ROM and rebooting, I think there is a race-condition between mounting the backup-copy of /pds and setting the MAC address. If the wifi-calibration is run first, then you will get the generic mac. But the next time you flash an update, you can get lucky and it picks up the right mac from /pds.

Cheers,

Michael
[Motorola Droid RAZR] ChungHung.Chen:
Dear Michael,

Thanks for your valuable information!

I've flashed multiple roms on my XT910, maybe some rom deleted /pds or by myself. :crying:

Does any problem will happen if /pds were deleted/empty? Camera calibration data? DRM keys?

Thanks again!

HDMI

Does anyone have a working hdmi output? When I plug in the cable, the phone recognizes it ( rotates) but no output (cable not connected) on my Monitor.
[Motorola Droid RAZR] mikeoswego:
Very interesting and thinks for this further info! All the folders are there in my actual /pds directory (running the stock rom that I've inferred uses a /pds mounted to the actual partition) but no files aside from the /pds/wifi/nvs_map.bin which I put there myself while running the stock rom.

I had an older Safestrap backup and restoring that gave me a /pds directory with many more files such as cameracal.bin, some stuff in /pds/public/battd, and more. I copied those files to my sdcard, rebooted into the stock rom and copied them to /pds and it appears that all is well.

I realized that I actually know exactly when I first got the generic MAC address and posted about it in another thread. I'd been watching the MAC issue and was checking it after flashing (I was doing most CM nightlies) and had decided to try another ROM. I'm not going so far as to make an accusation, but that post is here. At the time I was thinking Safestrap had something to do with this due to another problem that is not relevant to this thread. Now, everything is clear as to why my troubleshooting this other issue that arose in the same time span got inter-meshed with this one!

Thanks again for all your help!

My HDMI video works fine but there is no audio ouput. (The audio does work in the stock ROM so I don't think it is my hardware.)
[Motorola Droid RAZR] ChungHung.Chen:
Hi,

Do you mind to give me a copy of your /pds partition?

Mine is gone long time ago and CM11 is in my stock slot ...:crying::crying:

Thanks!
[Motorola Droid RAZR] mikeoswego:
Here you go. I think you already know that at least some of the files are unique to the individual device. :)
[Motorola Droid RAZR] d.casper.b:
Looks like Mr. Chen is in the same situation as me. CM11 is my stock too, and using this common MAC.

I actually took Ohmster's file, copied it to my phone and ran the calibration mentioned by Mr. Chen.

Worked after a restart or two. Now I think I have Ohmster's MAC, but that's no problem - I just managed to find my very first MAC address - and will try to restore it now, but I wonder if it was the only address I had before this generic came about...This address is dated October 2013, but I'm almost sure I had used another somewhere along the line. Not important anyways.

So, I did a clean install of M9 (thank goodness for Titanium Backup) and the first snapshot I'm actually working with (the M6 lasted less than an hour on my phone).

I cannot complain of any apparent issues, and if all holds out, I may stick with it a little longer than I usually do - it's becoming unhealthy this obsession ;)
[Motorola Droid RAZR] mikeoswego:
According to the specs, each individual device should have a unique, never changing MAC address. You should be fine using Ohmster's MAC unless you two should meet and want to access the same WiFi access point. :)

Here is a site that gives the device manufacturer based on the first 3 parts of the mac, http://www.coffer.com/mac_find/
[Motorola Droid RAZR] ChungHung.Chen:
Thanks for your sharing and I'll just copy camera and battery parts which should be public use.

Thanks for help again!!
[Motorola Droid RAZR] Dwillian:
I don't really know, but wouldn't restoring the stock ROM using Matt Groff's Droid Razr utility restore all the factory settings including unique MAC address?
[Motorola Droid RAZR] Ohmster:
Sure, it works just fine. Plug in the cable, the screen rotates to landscape, and the phone screen clearly shows on the HDMI monitor. Nothing special you have to do other than plug in the cables. Make sure your monitor is actually set to HDMI input. Many monitors and TV sets will not allow this input unless a cable is connected with an active signal present.

A proper install of cm11 and pa-gapps will work just fine, unless you have corrupted files or something. In that case, you would have to re-flash or at worst, reinstall cm11 and pa-gapps. But check the monitor settings first, they are notorious for not inputting HDMI unless the cable is plugged in with active signal present.

---------- Post added at 06:44 PM ---------- Previous post was at 06:38 PM ----------

Matt's Utility is awesome and will give you a perfect stock Jellybean rom. You also get Razr Blade to root the phone if you wish and you can install the rom with a full wipe or flash over to try and keep your stuff. I always use the full wipe. One caveat is that Matt's Utility is strictly for an XT912 phone. XT910 owners must go elsewhere.

Some clarification for Matt's utilities

Will give you more information and a couple of options if you need it.
[Motorola Droid RAZR] mikeoswego:
No, Matt's utility would attempt to restore the the MAC to /system/etc/firmware/ti-connectivity/wl1271-nvs.bin but the data for that comes from /pds/wifi/nvs_map.bin.

Apparently this all software based rather than having it hardware based like in an ethernet card.

On 08/04

Just wanted to say I took the latest update to 04/08 last night and this is running very well. No sign of black screen or any other issues. By looking at Settings/About Phone I realize this is the M9 snapshot. Now, I never take snapshots because I don't like them. They are old and not up to date like the nightlies. But this one installed the same as a nightly, works great, and when the next nightly comes along, I will update again.

This is probably the first snapshot I have no complaints about. But, that will not stop me from moving on. Cheers boys! :cowboy:

---------- Post added at 06:56 PM ---------- Previous post was at 06:53 PM ----------

You know, this just goes against the entire principal of having a permanent MAC address, like you say, an Ethernet card for example. Mine is like base 10 and hexadecimal. I don't have any problems with it, but it sure is funny looking. :p

I would like to take a moment to thank mikeoswego for his contributions. I can answer most questions across the board, but when it comes to digging deep into system files, even I have to seek out help for these kinds of questions. One thing we have here is a really good set of brains, and that, is one thing we can all be grateful for. :)

hi guys, just wanna ask about nightly 08/05 is this version are good. because i want to use it for dially now, i started to hate stock rom

now i used m7 snapshot.

last night i try to download m9 snapshot ota but always get bad mds/ wrong mds warning

i've try it for 3 times but always get the same, thats why i download the 08/05 nightly version

Someone please tell me how to use CMHome. I keep seeing all these updates for it, but I dont see how to enable it or use it...
[Motorola Droid RAZR] mikeoswego:
Thanks for the nice comment! It's good to be in a forum with like minded people!

I'm not seeing the red text and don't have a thought at the moment as to what might cause that.
[Motorola Droid RAZR] brkahughes:
I had to find it too: long press your home screen like you want to add a widget, use the the dots at the bottom to pull up the configuration and select 'search panel'. CMhome will give you an info panel when you swipe left to right on your home screen.

I just figured this out myself. Long press on lower part of home screen (I press and hold on the dots indicating which page you are on), swipe up, click on Search Panel, select CM Home. Now go back to home screen and swipe right until CM Home screen appears (same way that Google Now screen works).
[Motorola Droid RAZR] Ohmster:
Home? Oh, you mean Trebuchet. I am still using Apex but will switch to the real home of cm11, Trebuchet. That is where all the improvements are. Go to Settings, Home, and pick Trebuchet. When asked, say "Always" and you now have the official cm11 home screen and can start using all the theme stuff. I am too lazy to make a new desktop but I will. This is good enough now to make the switch. If you ever want to switch back or to something else, same procedure.

Enough of this snapshot M9 as good as it is. I am going for 08/05 right about NOW. Will let you know!

08/05 is installed. Snappy, no black screen at all. Same as previous roms, all is good. Of course I will update you all if something shows up broken but these are really solid roms that cm11 and stargo are pumping out!

;)

All that complicated stuff? I do not get that with Apex home launcher. Just as easy to use Settings/Home to pick your favorite Home screen, Trebuchet if you want the real cm11 Home, and say "Always". Done. :cowboy:

I don't get it, the red text went away on next refresh. It was like every post that had words like "is" and "that" were bold red. Strange, but gone on next refresh. Maybe a server glitch. Good now. :)
[Motorola Droid RAZR] Dwillian:
CM Home is not the same as the home screen when running CyanogenMod's Trebuchet Launcher. It's more like CM's start at having something like the Google Now screen if you use the Google Now Launcher.

See http://androidcommunity.com/cm-home-now-in-cm-nightlies-not-a-google-now-killer-20140718/ for a detailed description and screenshots.
[Motorola Droid RAZR] d.casper.b:
Thanks, I also didn't ever know where these changes were to be found in Trebuchet. So I just never used Trebuchet. And, to confirm, CMHome is not Trebuchet, it's like the "Google Now" page on Google Now Launcher.

Great that now I know where to customize this launcher. Trouble is I use Nova Launcher Prime, and since I'm quite content with it, I will stick to it for now.

I'll try Greenify

I'll try greenify. Thanks for this tip. I am new to XT912 development coming from old Evo. Of course I had this RAZR for over a year without doing anything to it. I have one for the store which is stock and my personal one with a RAZR MAXX battery and back cover modded :) Have not messed with roms in a while. Any good kernels out for this build? I like the rom and looking to speed things up. This Autokiller app isn't working like I thought lol.
[Motorola Droid RAZR] my2cents:
Thanks guys. You know, CM Home is pretty cool, but I like how quickly I can get to Google Now by simply touching the search button at the bottom of the phone. I wonder if we can set the search button to default to CM Home? It doesnt appear possible just yet, but maybe one day. I just like having it a touch away, rather than a few swipes away... ;)
[Motorola Droid RAZR] Ohmster:
I can't get that to come up. Maybe it is because of the Apex Launcher. Holding the screen at bottom brings up Apex menu to add widgets and wallpaper and stuff.
[Motorola Droid RAZR] brkahughes:
You have to be running trebuchet. Then as a one time thing you long press the screen, then drag up on the three dots at the bottom. This will open the trebuchet setup screen where you select 'search panel' and set it to cmhome. Now, when you are in homescreen, swipe left to right and it will open the cmhome screen. The information displayed will depend on the apps you have installed.

Oh I got it! I turned on Trebuchet and man, you get a LOT of cool stuff to play with in here. Hey man, this rocks. Good looking out, Brian! :D

This is really cool and I have been planning to go back to Trebuchet for a long time. The desktop is such a mess that I have to do it all over again. This CMHome thing. I set it but I for the life of me cannot figure out what it does. You have any idea, bra?

...never mind. It sets up a desktop for cm updates. I got plenty of desktops so this is a nice addition. ;)
[Motorola Droid RAZR] suprkain:
Anyone else interested in what cmhome can become? I see in the updates to come their adding more to it in some way although for now its probably more behind the scenes kinda thing.

Hi,

Could you help me to find if Trebuchet have "lock desktop" function now?

I've tried Trebuchet and Holo launcher HD for RAM usage comparison few days ago.

For what I see is Trebuchet : Holo = 6xMB : 4xMB.

Trebuchet is default settings and Holo has my custom desktop.

There are only two simple functions I need for choosing launcher.

1. "Lock Desktop" which in Apex/Nova/Holo but not in Google now launcher.

2. Less RAM usage.

Lock Desktop is useful when my children using my phone to play games... :p:p
[Motorola Droid RAZR] my2cents:
Check out the kids mode module in the xposed framework. It's clean, but the developer wants a couple bucks to let them access more than just 3 apps.
[Motorola Droid RAZR] CoreyWillWhat:
So I'm still having the audio cut out...seems only during media playback such as pandora or spotify. It's really frustrating. I'm on 8/5. Just did a full wipe and flash and the problem still persists. I dont think its a hardware issue as the audio will come and go on its own. Luckily I have a backup from before these issues were introduced in 7/9. I'm flashing my backup, 6/27. This will either confirm its a ROM issue or hardware issue. I'll report back.

[MENTION=4773308]vazersecurity[/MENTION] are you still having this problem?
[Motorola Droid RAZR] rgerrans:
It looks like there are a number of av commits in the next build, so hopefully that fixes it. I only see it occasionally on BT audio connections (I don't use headphones very often) but mine is very intermittent but does seem better / worse depending on the build.
[Motorola Droid RAZR] CoreyWillWhat:
Glad to hear I'm not the only one having this issue. Hopefully we'll get a build soon. Looks like Jenkins has been locked up for the last 12 hours.
[Motorola Droid RAZR] rgerrans:
Been running 8/5 build for 24 hours now. No orange icons yet (knock on wood). Much fewer black screens than I was seeing on 7/31. Still pretty laggy at times but battery life seems to be getting better with the newer builds.

Though I'm starting to find myself like [MENTION=4245858]Ohmster[/MENTION] and getting skittish when I see that many changes in one build. I must be reforming from my heavy crackflasher days......
[Motorola Droid RAZR] Ohmster:
Yes, I saw that feature in the new Trebuchet launcher. Go to Settings/Home and activate the Trebuchet Home Launcher. You can setup the desktop anytime you like. Once nice feature is to press and hold the bottom of the screen, right on the desktop dots to get the Trebuchet Options. They will come up, if you see a short list, hold your finger on the 3 dots and swipe up for the full menu.

One nice feature to activate is the Search Panel, change it to CM HOME. Now the feature that you want, I believe, I have not tried it, is at the bottom of the list, Protected Apps. Press this menu item. You get nine dots where you can swipe an unlock pattern, confirm the pattern, and you will have an app list of all your apps. You can check off anything you like, all of your apps or only the ones you do not want anyone to get into. This is pretty much ideal for what you want, so far as I can tell.

The alternative is a phone lock, same pattern or PIN number, where one cannot use the phone at ALL but for a 911 call. To activate this security measure, got to Settings, and right under HOME is Lock Screen. At the top of this menu item is your Screen Security. Mine is set for Screen Lock, Slide. Which is typical, slide your finger to unlock the phone. You can change this to None, Slide, Face Unlock (camera), Pattern, PIN, or Password. But then again, this will lock the entire phone. I think you are better off with the Trebuchet Protected Apps option so that the kids can use the phone, but only the apps you leave unlocked.

I have attached some screenshots to show you. I have locked 2 apps for demonstration and for you to see. You can check everything you do not want the kids to get into. Now I will remove the locks for myself as I do not need this feature. There is also a screenshot of the new CM HOME item so that you can see it.

Will this suffice for you my dear friend, Mr. Chen? :victory:

You are a good man, Mr. Chen. It is always a pleasure to assist you and even ask for your assistance when needed. Goodnight my friend. :cowboy:

Forgot the screenshots, dinner was burning. Here they are.

After running the latest version and tinkering with it, I am still having the issue. [MENTION=5586305]coreywallen[/MENTION] I am running 0808. I have noticed that when you say "Okay Google" (with the headphones disconnected) the sound will come back. That's how it is for me anyway. Can anyone else confirm this for themselves?
[Motorola Droid RAZR] ChungHung.Chen:
Oh, I think you may misunderstand what "Lock Desktop" I mean.

"Lock Desktop" didn't lock my whole phone nor protect apps.

It just lock my desktop "layout" to prevent icons/folders been moved/deleted or add new item to desktop.

I've tried Trebuchet myself last night and couldn't find "Lock Desktop" function.

BTW, thanks for your sharing and now I know that I can protect my apps from Trebuchet. :good:
[Motorola Droid RAZR] d.casper.b:
Ohmster, he doesn't want to lock his phone - in fact he wants to leave it open and accessible. What he wants to do is lock the launcher from any modification. If the launcher is locked, you can't place/move icons, add/remove screens etc. Basically, you can use everything, but can't change any launcher settings (I think widgets are also not allowed to be added/removed).

Trebuchet does not (yet) have this.

I'm still on M9 and it works OK.

Although, I often have issues changing wallpapers (and this is not new to me).

I still think audio stops working for me as well. I received a notification, it vibrated but no tone. Also, I know I was tired, but I missed my alarm this morning (I'm unsure if it was me or if the audio wasn't working); and this resulted in me missing my train and having to catch another (more unpleasant) train - but I cannot confirm if the audio sounded or not.

As I've also read with other builds, things are feeling quite laggy; maybe the first time I can actually say I feel it too now. I noticed it in Chrome and I'd never had it lagging like this.

Casper, you are really comming out of your shell and are proving yourself to be quite a valuable asset here at CM11 Razr forums. That is really neat, you are very intelligent and have a lot of good ideas and questions. Great to have "The new Casper" with us.

Lock the desktop icons. Man, I would never have figured out that is what Mr. Chen wanted because I would not likely use such a feature although it makes sense. It is late, 4:00 AM, but I want to take another look at the App Lock settings. Maybe there is something about changing the desktop in there. Or Apex might have it, it is very much like Trebuchet and the pro version costs very little money, less than five bucks. Let me switch back to Apex to see. Apex has a LOT of settings, it takes a few minutes to get my desktop back and I have a decent setup for Trebuchet now. Yes, in Apex settings, there is a menu item for Lock Desktop and I have it enabled. Now I must see where that feature is. Yes, you get two Apex menus. One for the menu, one for settings. Here is a screenshot showing the menus and one showing the desktop lock.

Oh for goodness sakes, .png format exceeds the 470Kb size limit. Let me convert to .jpg @ 85% compression. Here you go.

Here is a screenshot of locking the desktop from changes and one showing the settings. Apex Pro Launcher is a really good launcher and is free. To get the pro version, it is only a very small dollar amount. I get my disability check once a month and if you for real do not have the 3 or 4 dollars it costs, I would be very happy to buy it for you, Mr. Chen. No need to return the favor, all good things return to us as do the bad things in life. Yin and Yang, is that what you call it? The link I provided is in English because I see the =en at the tail of the URL. The launcher may be available in Oriental languages if that would make you more comfortable, Mr. Chen. Go have a look, it is for all intents and purposes Trebuchet with LOTS of options, including saving and restoring your desktop. I have the money covered if you need it to upgrade. Now go install it, try it, and see if it does what you want. You can always switch back from the Settings/Home menu.

I hope that this is helpful, Mr. Chen. As you are a most helpful gentleman. Goodnight all! :cool:

Audio always seems to work for me when I need it to, phone calls, alarms, but not when I want it to, Pandora, Spotify. Hoping all these AV commits in the next update may fox it.

As for performance, do some research on the governors and I/o schedulers under the performance settings. I just recently switched to "performance" governor and "deadline" I/o scheduler. Supposedly there's evidence to suggest keeping the CPU at max MHz, which is what the performance governor does, can increase performance and not take that much more out of the batteries by returning to idle faster by finishing the processes quicker. Also under "memory management" I have both "purging of assets" and "kernel same page merging" checked. Give those a shot if you want. As for me, my phone is flying faster than ever on 08/05.
