Hi people This is my first post in the forum ... So hopefully my question is well placed. I previously searched this forum for an answer, and since I did not find one, Maybe my question is an interesting /valid one:
I have bought my nook colour 4 days ago. I rooted it and then installed Cyanogen Mods ... I am currently using the latest nightly with overclock kernel (1300 Mhz). I tested also older nighties (started with 64).
I press the Bluetooth softbutton, it keeps in "dark green" for some seconds and then turns off.
I go to configuration ,and turn on Bluetooth in the network options, it says "Activating" for a while, and then it goes back to inactive.
I tought that this was a solved issue and our nooks had their bluetooth working may be that my nook is too new, and b&n took the bluetooth module away ?
Regards,
Enrique
I have just bought a nook as well and this happened to me. after searching the forums I found a couple of suggestions and what worked for me was the hard power off method.
Basically just hold the power button down till the nook turns off, then turn it back on.
After it fully starts up immediately try to turn bt on. For mine, it worked right away and I just always leave bt turned on.
It worked - at least kinda of...
Hi n3cr0tic!
Thanks for the tip ... it successfully turned on the bluetooth. Now the thing is that I can see my phone, but apparently the nook does not expose any service at all (like "file transfer" for example) nor can see the services that my phone readily offers.
On the distance side, I would say that it discovered my phone up to two meters away ...
any further help is appreciated ... I am new to android itself, so it is most probably something pretty obvious I am missing, like for instance installing "the bluetooth services daemon" or similar ... I will search around...
Regards,
Enrique
Similar problem can't find the answer
I used Manual Nooter on my Version 2.2 Nook and I can't find any Bluetooth settings at all. I go to NookColor Settings on Zeam Launcher and there is no option for Bluetooth anywhere. I went through all the settings and NONE of them have anything that says bluetooth. I've tried searching the forum but most of the threads I've seen don't seem to have this problem.
Thanks for your help.

i don't believe BT is currently supported in rooted stock - option is not available in settings.

My wifi won't start. Whether it's through TouchFLO's comm manager or Window's own Wifi connection, it will give me the "Busy" rotary and then nothing happens.
I know exactly when the problem first appeared, though. I was using WMWifirouter (an ancient version, .8 or .9 something) while it was tethered to a Macbook for power (I think on ActiveSync, but I don't remember). From what I gather, that might not have been a good idea, or, rather, that theoretically should not have worked. But, it did. I disconnected the phone, and since then I've had the aforementioned wifi issue.
I've searched XDA and Google, and it seems the best answer I can find is to hard reset and see if it works. However, it seems that for a large majority of people who tried this method, the problem doesn't go away.
I'm hesitant to try a hard reset, as my HD's been working fine for the past 5 months and I've got a lot of time and work put into it, when it might not get me anywhere.
Hence, I'm asking if anyone's come across a solution to this problem that might work. I'm hoping it might be as easy as a registry tweak (I have seen some "solutions" that involve the registry, but they don't appear to apply in this case).
Since I'm in the US, and the HD is not officially provided by any carriers, I might have a lot of trouble getting any kind of warranty work done on it, and that also entails losing the phone for 2+ months, as best I can tell.
I might try flashing a newer HTC ROM, although I would be pretty mystified that my old ROM suddenly wasn't good enough. Maybe it's just that a new factory ROM would place the correct registry settings back in order?
Sorry for the long post, I'm just frustrated that I am unable to use wifi and that I'm starting to think the only solution will be to get a new phone or live without it.
Does anyone have any thoughts?
(I've looked at several threads on XDA already, none of them were at all resolved or even directly discussing the HD, so I think it's okay to post this thread.)
EDIT: I could tell I was going to get no response here, so I just went ahead and hard reset the device. That seems to have fixed it, for now. Wifi's working how it should. I'm adding this edit here for anyone else has this problem.
Just a bump, and also to add that when I run WMWifirouter with logging, it shows that it fails to Rebind the WLAN and also the CM-Set fails, if that is any clue.
Another detail, I notice that under Settings > Connections > Wi-Fi > Advanced > Advanced, there is nothing under Status, MAC, IP...I'm guessing that will always be empty if it's not connected? If not, are there values I should fill in?
I am happily using the build as my daily ROM.
However, it is not working with all the QR app. I saw one member asking same question someday ago, but did not see reply so far.
Anyone experiencing same issue or has it been sorted out.
Many thanks in advance.
Please read the ROM's wiki and there you can see that you need to use NeoReader for barcode scanning.

About winLogo key
Hello, I want to ask my question here because I am not able to write it on nand topic. I'm using this rom and its really great. My question is; when you press winlogo key gently -Lol really- settings menu is opened and the default action for this key is this, but when you normally press winlogo key, it acts like home key and returns to home. Is it a way to change/fix it? Thanks..
Did you try rebooting?
yes, I've been using it since 5 Feb. and booted many many times..
Booting
Hello!
Yesterday I installed this rom and I have a problem. After installation, when the phone resets everything turns around all the files to download, then shows a screen that says "ANDROID" at which point everything becomes. How many would not have waited for the screen disappears and nothing further changes. I left it switched on the phone at night, because I heard that when you first load all the files but that did not help.
Do you have to install a kernel update CLK?
Does anyone know a solution to this problem? Please help!
greetings
I have a garmin nuvi 3790 navigation, but unfortunately, the navigation system can not find the HD2 (with NexusHD2 ICS-4003-CM9 V1.3) via bluetooth. Does anyone know how to fix this. HD2 can find the navigation device but not vice versa.

There was a post about this in the dev thread for 1.3, exact same issue but not sure if it was the same device, as of yet (from me reading it 70 million times a day) it hasn't been answered. Keep checking that thread and the wiki to see if anything comes up.

For a number of reasons, I'm thinking of rooting my Droid R2D2 and installing CM7.2. Given that I'm on 2.3.4 and the hoops required to root it, I would love it if someone could verify that the following features all work on their Droid2 or R2D2 with CM7.2. I haven't been able to find a consolidated list of what does or doesn't work on this particular phone. I'll update this post with reported statuses as people respond for others to use as a reference.
Comments in blue are consolidated feedback from others. Comments in green are my own experiences after taking the plunge.
Phone calls: Yes Confirmed
3G Data: Yes Confirmed
WiFi: Intermittent. Sometimes people have to reboot every time you toggle, but not everyone has this issue I've noticed sometimes when on WiFi I lose all data connectivity. Disabling WiFi sometimes fixes it, but not always. Rebooting seems to do the trick every time though.
GPS: Yes Confirmed
Phone-over-Bluetooth: Yes Confirmed
Stream Audio over Bluetooth: Yes, possible lag entering menus/rotating screen/unlocking due to using power amp Pandora works fine for me
Still Camera: Yes Confirmed
Video Camera: Yes Confirmed
Physical Keyboard: Every key except 'ALT LOCK' Confirmed
Motorola Desktop Dock detection/integration: Yes, though it doesn't seem to remember that I've hit the brightness/dim button between inserts as it used to when on stock.
Motorola Car Dock detection/integration: Yes
SMS/MMS (I use Google Voice for most of my SMS needs, but for sake of completeness):Yes SMS - yes. MMS - haven't tested.
In addition, if you could address the following, that would be great: One of the reasons I want to get rid of the installed firmware is because of a strange problem I have when I stream audio over bluetooth to my car. The problem is: when I'm streaming audio, and only when I'm streaming audio, if I use my car's steering-mounted controls to initiate a phone call, it seems to sever the bluetooth connection with the phone. I have to manually re-connect the car to the phone (not re-pair, just re-connect). When I'm not streaming audio, using the steering wheel-mounted controls don't cause the sever to occur. I use both Pandora and iHeartRadio, and have seen the same problem in both apps. Using the iOS version of the same apps on my work-issued iPhone don't have the problem, so I don't think it is an problem inherent with my car, I think it is an issue with the Android installation. If switching to CM7.2 suffers this same problem as the official 2.3.4, it wouldn't be worth the effort to me to switch. But if it DOES fix the problem ... I might be more forgiving if everything in the above list doesn't work fully. I still suffer the same problem.
Thanks in advance!
Other things I've noticed:
Airplane Mode: I've noticed that trying to trigger Airplane Mode doesn't seem to work properly. When I attempt to trigger it, nothing appears to happen. If I then reboot the phone, I see the airplane icon in the status bar, data doesn't work (as one would expect when in Airplane Mode), but the Bluetooth icon is visible, as if Bluetooth were still turned on. Attempting to turn off Airplane Mode also requires a reboot.
Lock Screen: Initially, changing the settings for the lock screen worked just fine. Now, for some reason, the settings don't seem to "stick" ... I set them, but they have no effect. But, if I then reboot, the settings that I tried to set take effect. So they are being persisted somewhere, somehow ...​Airplane Mode and Lock Screen: Originally I noticed the two above items. I just did a factory reset of the phone (Settings --> Privacy --> Factory data reset), and the problems went away. Airplane Mode seems to work properly, and the Lock Screen settings update as expected, just like when I first installed CM. I didn't do all that much previously, so I can't imagine what broke these the first time, but if I happen to recreate the problem and isolate the cause I'll mention it here.
ADW Launcher: When Cyanogenmod first booted up, I couldn't add, move, or remove anything from the default home screens by long-pressing. The haptic would trigger, so I know it was recognizing the presses. By going through the ADW settings and choosing simply to restart ADW, everything started working fine.
Lock Screen: I love the flexibility and customization it allows. At first though, I thought it wasn't showing the time/date of the next upcoming alarm. Then I realized that by disabling the "show next calendar event" feature, it would show up in the same place that the calendar event was otherwise appearing in.
It's fast!: The phone feels MUCH more responsive than when I was on stock.
Phone calls: Yes
3G Data: Yes
WiFi: Intermittent. I have to reboot every time you toggle, but not everyone has this issue.
GPS: Yes
Phone-over-Bluetooth: Yes
Stream Audio over Bluetooth: Never tried
Still Camera: Yes
Video Camera: Yes
Physical Keyboard: Every key except 'ALT LOCK'
Motorola Media Dock detection/integration: Never tried
Motorola Car Dock detection/integration: Never tried
SMS/MMS (I use Google Voice for most of my SMS needs, but for sake of completeness): Yes. I use both also

Does it do this with your standard music app while playing music off your SD card?
Your logic seems sound enough, but you assume Android is a perfect OS. It might just be the way Pandora and iHeartRadio are designed to handle that situation in the Android operating environment and it might just be a bug across 2.3.4. My suggestion to you would be to try these same exact things with a couple DIFFERENT Android phones (a friend's, the wife's, etc.) to see if that's just how it plays out within the Android OS. Worst case scenario, that's just a problem with the apps themselves and you write an email to them asking for an update with a solution.

Sadly, everyone that I know is an iPhone fanboy. I'm the only one with an Android-based phone!
I'm also aware that the ROM has baked-in support for Motorola's media and car docks, though I don't own one to tell you how well it works. I assume its the same code, just stolen from source, and I've NEVER seen anyone complaining about it on Gingerbread. Maybe head over to the Droid 2 Accessories part of the forum and see if there are any complaints.

Per your advice, I ran a couple of more tests, and found the following. In addition to severing the bluetooth connection when streaming audio from Pandora or iHeartRadio and using the steering wheel-mounted controls to initiate a phone call, the bluetooth connection also gets severed in the same manner when streaming sound from YouTube.
Interestingly, it does NOT sever the connection when streaming audio from the local media player or through Play Music when streaming over 3G. However, even in this circumstance, if I hit the steering wheel "Mode" button to switch to AM/FM, it severs the bluetooth connection. If I recall from past tests, this also would also sever Pandora/iHeartRadio, though I didn't repeat that this morning.
So ... it's not just Pandora or iHeartRadio, but some of Google's own software, though sometimes only when switching radio modes and not always when placing a call.
Is anyone out there running CM7.2 connected to a car and able to verify whether the same problems plague CM7.2 as stock 2.3.4?
2.3.4 and the hoops required to root it,

it's not that difficult, just need a decent pc
download iso file (50mb),
mount image to cd, dvd, or usb drive
reboot pc to drive
run program, read onscreen instructions, takes about 10 mins or less
wipe cache, reboot
done your rooted
just know how to boot to bootloader and recovery, read http://droid.koumakan.jp/wiki/Welcome
written for d2G, but same steps
Stream Audio over Bluetooth: Yes, possible lag (music pausing/skipping for a split second ) entering menus/rotating screen/unlocking but maybe because I am using power amp or the kernel that I am using
Dock: There is a dock menu in settings that looks to be specific to this phone (as in I have not seen it on other cm7.2 phones) so it may work
Edit: FYI I had a fun (hard) time getting from stock (froyo) to CM7.2. I had to flash the stock (gingerbread) before I could get to 7.2 (Someone here provided me the file to flash which I may be able to dig up)
Well, I hooped myself crazy, am rooted and on 2.3.4 - and the CM7.2 install script still honks that I'm not on the right version.
Anyone else seen this one?
(I realize I'm a little late to the game - I just got a D2 off of craigslist...)

You may need to tweak the Cyanogenmod installer. See the following post for instructions on how to fix. Copying/pasting the instructions here for reference. This worked for me. I ran CM7.2 for quite a while, but eventually got rid of it due to my R2D2 having WiFi issues under CM7.2 (it would sometimes stop having internet connectivity over WiFi, and the only way to fix the issue was to reboot).

GregMoens said:
Look like you're failing the check_kernel script. This was put in place to prevent someone with a Froyo based kernel from flashing a CM version that required the Gingerbread kernel. If you open up the cm-7.2.0-droid2.zip file and look at /system/etc/check_kernel, you'll see that the required kernel version is 2.6.32.9-gca08d89, which matches my Droid2 exactly. I'm assuming your version does not match. That 2.3.4 update must have bumped the kernel version. This new kernel may or may not work with CM7.2.
Couple options I can think of. You could change the required version in the check_kernel script. Or you can blank out that entire file and replace it with:
#!/sbin/sh
exit 0
You could also edit the main update script found under /META-INF/com/google/android/updater-script and delete this line:
assert(run_program("/tmp/check_kernel") == 0);
Just make any of those changes, repackage the zip file, and try flashing that. You could very well get stuck in a bootloop due to the new kernel being incompatible and you may have to SBF back to rooted 2.3.4 and live with that for now. Good luck!

Hello XDA users
I would like to know if is possible to any of you answer some questions about this device:
1) I was using the stock ROM some months, and i noticed that some times it just freeze. i mean, the phone would not give any kind of response unless i take off the battery or hold the power on button a while, then press again and turn on this time. I really hoped that this issue was from the ROM, but now exactly the same happened today using the JELLYBLAST v3. Is there some explanation for this behavior? or is just what i get for such a low price smartphone?
I didnt saw that happening yet, and the battery was not totally out, i remember that i saw at least 50% charged the last time it happened.
2) Why i cant connect to a bluetooth HID device? the stock rom and the JELLYBLAST said the same: that cant connect. I saw somewhere that this is possible with Cyanogen, but how come? i really searched at the store for a app that could do that for me, but not a single one worked (from the ones that i found, research made 3 months ago).
I wanted to make use of my bluetooth keyboard from Palm.
Thanks.:good:
Many people are joining xda on daily basis. Some of them join the forum to get custom ROMs while some join in order to get some of their problem that they are facing with their phones solved.
There are dedicated threads for ROMs but what about HELP/QUESTIONS??
People generally straight away start a new thread to get their doubts solved. But this can lead to chaos in the forum.
I'm creating this thread as an alternative to *New Threads* that aim to resolve a question.
Not only this, this thread can also become a Database kind of place where people can look if their question is already solved or not...
I request all members of the BLUE VIVO AIR sub-forum to help and answer some questions posted here if they can.
I hope you guys get the idea behind this thread...
Hello
I am new here. I agree with you making a separate thread for q/a. So is this thread for all the devices or for only high end devices..?

Tried all root tools so far and couldn't root it. Some people had the luck to root it, I heard. But it depends on the firmware installed.

Camera software non responsive.
Good morning ,
Good people. I Just received my BLU Vivo Air (black) yesterday and love it for the mid tier phone that it is. I love the form factor and how light and thin it is.
Right out of the box there was a minor update for bug fixes and performance. After that everything was still working fine. Including camera. Now this morning I attempted to use "CharmCam" once again to take a night shot. When I loaded the app there was a light haze and I could see the image behind the haze. It was as if the camera lens some how over exposed to allow more light in. The issue is that the software was also non responsive to the point of not even being able to take the picture. So I rebooted and still same result. I then tried the native camera app and this worked fine the first time and then the same haze and non responsive software buttons after the first picture.
Once I get a chance I am going to do a factory reset and see if that fixes the issue.
Still love everything else about the phone.
I'm looking for some info on the stock launcher to see if it is even worth while keeping it versus installing GEL or Nova. The icons on screen don't bother me per se, I have an iPhone.
Issue with bluetooth phone audio in the car
Hi Everyone,
The issue i'm having with my Blu vivo air is the phone audio doesn't go through the car speakers or use the car mic. I'm connected through bluetooth and I can play all my media audio through my car speakers. It's only when i try to pick up a call and talk that this feature completely doesn't work.
I understand that with so many different car head units functionality can be a little different. I'm just seeing if any others are experiencing the same thing. I had no issues previously with my htc one. I just started loving this phone too, and this is a big feature for me. My only work around is to pick up my phone and take it off bluetooth and answer it normally, which i shouldn't be doing in my country. I own a scion fr-s stock head unit for those wondering. I hope there will be an update to fix this issue......
Thanks

Have you tried to format the phone? I saw a post the fixed WiFi connection by formatting.
Also, a few of the users here has already received some updates. I believe the most recent is v11.

WiFi does not work
I just got mine days ago, the WiFi was working when i first set it up but then it stops for no known reason. i have done a factory reset on the phone and was able to connect to my WiFi network again, but as soon as the phone finish updating the WiFi stops working again. does anyone knows how to fix this? i really like the design of the phone, but i'm going to return unless this WiFi is problem permanently fix.
Vivo Air Battery Issue
I find Vivo Air to be excellent phone. Battery life is great, with 3G enabled it lasts more than 3 days, but it is my wife's phone and she mostly uses it for calls and viber.
The only issue that she has it that battery percentage is not shown correctly. The percentage goes down as it should be and after some time it will just go up. For instance it can go to 55% and the next time she lights the screen it will show 85% full. So, she does not know what actual battery status is. We tried with installing battery apps, DU Battery Saver, but it shows wrong battery percentage as well.
I have opened case with BLU company and they advised to perform factory reset, without wipe data cache, but it did not help.
BLU is a little bit slow with answers, so I tought that maybe somebody had same problem and can advise how to solve it.
So, any ideas what to do?
