[G3 Q&A, Help & Troubleshooting] hdcp:
I have the D850 and for some reason I am unable to save contacts to the phone. I am only given the choice to create the contacts to my Google account or SIM card. Am I doing something wrong?
[G3 Q&A, Help & Troubleshooting] hdcp:
Well, it turns out the problem is caused when I freeze the AT&T address book app. Unfreezing it does not fix the problem of saving contacts to the phone. It still only gives the ability to save it to Google or the SIM card. The only way to correct it was to do a factory reset and just not freeze the AT&T address book.

Has anyone else had this issue?
[G3 Q&A, Help & Troubleshooting] michael.s.under:
Are you google free?

Is there a benefit to saving to the phone as opposed to google? If you are google free, then I understand.
[G3 Q&A, Help & Troubleshooting] hdcp:
No real benefit. I just prefer to keep them on the phone as opposed to Google. One thing I do not like is Google (in particular GMail) seems to make everyone I've ever sent or received an email from is a contact.

[Moto X Q&A] FleetPhone:
I have been trying out a few custom roms, and both Slimrom and cyanogenmod both have non-function WiFi and Bluetooth. I have no idea why my Verizon Wireless developer edition Moto x has so many issues with this, while everyone else seems to have functioning WiFi and Bluetooth on different models of the Moto x, such as XT1058, etc. I do not know what is so different on the XT1060 that prevents the WiFi and Bluetooth from working. Both threads for both of those roms on xda have no people complaining about WiFi and Bluetooth that won't even turn on. I have tried like every build, and have done clean wipes every time before, and still nothing. Every time I try to turn on the WiFi on from settings, the switch goes to right to the on position but is always grayed out, and WiFi routers never appear on the list. According to kernel log files, the Bluetooth driver just crashes without warning, and the WiFi driver does not have required firmware to run. So what can I do to solve this problem, and also does anyone else experience this problem? Thanks.

[Moto X Q&A] samwathegreat:
The problem is highlighted in red. You have somehow erased your WCNSS_qcom_wlan_nv.bin file.

You will need to get these files from another user, and place it in your /persist folder. This is the only way wifi and bluetooth will ever work for you.
[Moto X Q&A] FleetPhone:
But I did not do anything other than flash the rom and that's it. It came like that with the rom. So I tried coping the wlan firmware files from stock, and that did not do anything. It still refuses to start. I will try some other things.
[Moto X Q&A] samwathegreat:
It won't do any good. Those files are located in the persist partition.

It is called the persist partition for a reason. When you flash a new rom, persist is unaffected. It is unique to YOUR phone, and your phone only. You can flash the stock rom as many times as you would like but the persist folder stays untouched.

I don't have any idea how this happened to you, but it is most definitely your persist folder. You would HAVE to be rooted/unlocked for this to have happened.... I can only guess that you somehow erased or formatted /persist.

Do you have "Root Browser" installed? If so, browse to the "persist" folder. What files are inside?

See here: http://xdaforums.com/showthread.php?t=2619553
[Moto X Q&A] FleetPhone:
Yes I do, and the persist partition has 3 files in it. They are named .bt_nv.bin, WCNSS_qcom_wlan_nv_calibration_persist.bin, and WCNSS_qcom_wlan_nv_regulatory_persist.bin. However, when I restore back to stock rom after I am done testing with the broken rom, the stock WiFi works just fine, even with that same persist folder. So if it has something to do with persist folder, then I have no idea what is wrong. Should I not wipe system before I install my rom?
[Moto X Q&A] samwathegreat:
You only have 3 files??? Because my X has 4 files:

.bt_nv.bin

WCNSS_qcom_wlan_nv.bin

WCNSS_qcom_wlan_nv_calibration_persist.bin

WCNSS_qcom_wlan_nv_regulatory_persist.bin

Just as I had said in my very first reply, you are missing WCNSS_qcom_wlan_nv.bin

Here: http://xdaforums.com/attachment.php?attachmentid=2760949&d=1400950032

Download the file, and place JUST the missing file back in /persist

The permissions should be: rw-r--r-- (permissions must be set correctly)

Does WiFi work now??
[Moto X Q&A] FleetPhone:
Indeed, there is only 3 files in that folder. However, there is WCNSS_qcom_wlan_nv.bin file in system/etc/firmware/wlan/prima that is system linked to the persist folder. However, that bin file is 0 bytes, which is pretty suspicious. If there is another file suppose to be there, how could I get it back? Do you get a persist folder when you do a factory image restore (such as restoring .img files using fastboot)? I do not think I ever touched the folder, but maybe something went wrong.
[Moto X Q&A] samwathegreat:
See the edit to my previous post. I linked the file you need. MY WCNSS_qcom_wlan_nv.bin file is 29.08KB.

Please try copying that file into your persist folder, and then changing permissions as I advised in the last post. Reboot and advise if WiFi is working now.
[Moto X Q&A] FleetPhone:
Yes WiFi now works, It is just strange that WiFi worked on stock 4.4.2 without that file present in the persist folder. And I just used a Motorola factory image like a day or two ago with fastboot. Strange. Well Bluetooth also works. Thanks, however how do you get a "new" persist folder? Do you get it from the Motorola factory image, or is it impossible.
[Moto X Q&A] samwathegreat:
It is impossible. Something went wrong and the file got erased at some point. You SHOULD NOT have to do this again. /persist stays untouched between ROM flashes. Not even using RSD Lite to restore back to 100% stock touches the persist folder.

If you leave it alone, it should stay working forever, unless you somehow delete it. You cannot get it from the factory images...fortunately you were lucky enough to have someone willing to help you and "donate" the file from their phone :P
[Moto X Q&A] FleetPhone:
So Now I have 4 files, plus that lost+found folder that is always there. The other two files, not the .bt or the wlan_nv, permissions are lrwxrwxrwx and system linked to somewhere. Is that correct, the permissions? And from the log, It seemed that the phone tried to download a new WCNSS_qcom_wlan_nv.bin one from somewhere, but failed to do so. Thanks for your help, now these custom roms will actually operate as they should.
[Moto X Q&A] samwathegreat:
Yes, those are the correct permissions. You are all set!

I AM very confused as to why the stock ROM worked for you without the missing file, but it is supposed to be present on every Moto X.

You should be able to change roms all you like and the WiFi should "Persist" (haha)

Just FYI, my /persist folder has this:

data (folder)

lost+found (folder)

omadm (folder) - I believe this is unique to Sprint devices

omadm_cust_database (folder) - also possibly unique to Sprint devices

omadm_database (folder) - another possible Sprint-only folder

prop (folder)

prov (folder

usf (folder)

and then the 4 files I listed earlier

I wonder if you formatted or erased /persist at some point?? Wonder why you don't have all the folders I have...

As long as everything is working, I guess it isn't a problem...strange though...maybe ALL those folders are unique to Sprint devices?
[Moto X Q&A] FleetPhone:
Mine Is a Verizon phone, so that could be why. Also the early versions of twrp may have wiped everything once as it was not offically supported at the time. Explains all those weird Motorola errors I would get when fastbooting ( I fixed those eventually). I hope I don't need any more files, I would need to hunt them down. And now have an official twrp recovery. But thanks anyway.

wifi bluetooth problems!!

I'm having the same issue, but reading the posts is very confusing, if someone can post the step by step to be done I would appreciate it. For months I am with this problem out, what caused me to increase my data plans by not being able to use wifi. PLIS I NEED SOME HELP =(
[Moto X Q&A] FleetPhone:
Well, first you will need to use a file manager to look inside the persist folder, which is located in the root directory. You must have these 4 files:

.bt_nv.bin

WCNSS_qcom_wlan_nv.bin

WCNSS_qcom_wlan_nv_calibration_persist.bin

WCNSS_qcom_wlan_nv_regulatory_persist.bin

If they are there, you should be fine. If you still have a problem, then this solution is not for you.
[Moto X Q&A] PaulinhoCy:
Help ... I'm having the same problem :(

Hello friend!

I'm new here, I'm having the same problem, however I downloaded files from your MOTO X and put it in my folder PERSIST, then I put the Wi-Fi only worked twice. Do not know if it was something wrong that I did more I changed some files in the folder (/ system / etc / firmware / wlan / prima) I replaced the file with the WCNSS_qcom_wlan_nv.bin has PERSIST in the folder ... directory (/ system / etc / firmware / wlan / prima) got the files (WCNSS_CFG.dat, WCNSS_qcom_cfg.ini, WCNSS_qcom_wlan_nv.bin), you could make available the files in this directory? Or do you have another suggestion?

Note! There are times that the bluetooth connects any device located not more, then it stops working.

Wifi and bluetooth also not work on Moto X XT 1049 - Republic Wireless

All,

I've got the identical problem on a Moto X XT 1049 from Republic Wireless: unable to get wifi and bluetooth to go on.

1) Do you think it is possible that the file provided in this thread, for a 1060, would work on my 1049?

2) How do I put that file in the persist directory? My phone is not currently rooted.

(I'm a relative newbie so spell it out for me, if you don't mind. Much appreciated).

Same WiFI Problems

I Have XT 1058 device and I've got same WiFI issues(4.4.2). In my /persist folder have:

Prov(folder)

usf(folder)

.bt_nv.bin

WCNSS_qcom_wlan_nv.bin

WCNSS_qcom_wlan_nv_calibration_persist.bin

WCNSS_qcom_wlan_nv_regulatory_persist.bin

The problem is, the last 2 files in the list, have a size of 0.00 B

I Have replaced them with the files provided from samwathegreat(and following the -rw-r--r-- permissions), but when i restart or shutdown, the files appears as if i haven´t done any change (0.00 B Size again)

I also replace WCNSS Files(except cfg.dat and cfg.ini) on system/etc/firmware/wlan/prima with the ones provided, 3 of them had 0.00 Size, but fortunately the changes persists after reboots or shuwtdown.

I'll really appreciate your help, sorry for my awfull english

I have a XOOM on my same network and that connects every time without any issues.

I have attached the logcat as a screenshot, can someone please take a look at it?

Also the two files in the '/persist' folder are linking to another file in '/system' with the same name.
