possibly, but try doing a full wipe, three times each of everything, and wiping cache and dalvik and fixing permissions after the ROM, then revolt directly back into recovery, and then install gapps, then wipe cache , dalvik, and fix permissions again then reboot into system

Not sure why but that order ALWAYS see to fix stupid little FC's and other random bugs for me

Why do you say that?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] blackroseMD1:
It's had a couple errors. That said, though, a couple of the other builds tonight did too, and they ended up building successfully, so hopefully ours will too.

Edit: It did build correctly. Just flashed it. Seems to be running fine so far.

Here are detailed instructions for the Canadian s3 owners who get status 7 errors:

1. Install Total Commander from the play store.

2. Download your choice of cm10 nightly or stable.

3. In Total Commander find the cm10 zip you just downloaded.

4. Total Commander will allow you to navigate the files inside the zip. Go to /META-INF/com/google/android/ and unpack and edit the updater-script file

5. The first line in the updater-script file is the device check. It checks the build.prop file on your device for the value stored in the the ro.product.device line. By default it looks for "d2att". Either remove this line, comment it out, or change it to read "d2can". Exit and save the file, repack it into the zip when it asks.

6. Reboot into recovery

7. Make a nandroid

8. Factory reset and full wipe.

9. Flash CM10. Should be successful this time no errors.

10. If ROM flash is successful flash jb Gapps of your choice (hopefully you downloaded them already)

11. Reboot system and enjoy your new ROM.

Consider a new nandroid once you're successfully up and running.

If you brick, own up to your mistake, don't blame anyone but yourself and SEARCH for the potential solution I can pretty well guarantee you aren't the first to experience whatever possible problem you run into. It will be documented somewhere in these forums.

Hi guys. I've been having this problem for a while with tethering. I'm now on the latest ROM. I now realize that I can only tether when I'm on H+ or lower not on lte. I'm on rogers. APNs are set and I've done a factory reset and everything. I can't get tethering to work on lte. Is this just me? Is rogers restricting me from tethering??

Update: I searched this thread seems like there are others experiencing this also. Hopefully a fix comes soon.

Yeah, HDMI-out appears to be broken again.

It was working just fine for me on a nightly a few days before CM10 "STABLE". I tried it again last night on CM10 stable, and no-go, and again on today's nightly (11/17), and still nogo. The first plug-in after a reboot shows a signal, but no output, and subsequent re-plugs show no signal. Tried all the old tricks to try to get it working too (disabling hw overlays, and reconnecting the mhl cables in different orders (power first, etc))

Next week's 4.2 will cure all. hah.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] astralmind:

Alternatively, there is a software navkeys zip somewhere on XDA that will put the software buttons from stock 4.0+ on the bottom of your screen, and you can just drag up from there. Forgive me if I don't direct you to the file, it's been months since I found that and don't have a bookmark to the thready anymore.

My GPS totally disappeared before. I tried this method and it didn't work. I ended up having to Odin the stock firmware and then do a factory reset while booted up (not in recovery). That brought my GPS back. Just a little tip if the quoted method doesn't work.

Stock SMS

I have a question, I was using GO SMS before and I decided to give the stock SMS app a try, whenever I choose a contact to input a message for some reason it doesn't put the full number it just puts a 1, then the area code is missing and then after that is the last 7 digits, I cleared cache for the app and still nothing

If you had bothered to simply search this thread for "changelog" (it's difficult, I know.) you would have found:

http://changelog.bbqdroid.org/#d2att/cm10/next

and

http://cm10log.appspot.com/?device=d2att

BBQDroid pulls their logs directly from git, whereas the appspot log I believe pulls changes from Gerrit. The reason I mention this is that sometimes things get merged on git without going through Gerrit, and sometimes something new gets created on git a few days before it actually makes it into a build.

How is a closed source piece of Samsung-only software found only as part of Samsung's Touchwiz UI NOT proprietary?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] zmore:
Because the so-called "Pop-up play" mode isn't protected by (lame) software patents, so anyone can implement it if they want to, and a few other media player apps (like DicePlayer) already have. It's sortof pointless on a phone, though, IMO.

Download a fresh cm10 nightly and the proper gapps and put on the root of the phone.

Assuming you have CWM

Go into recovery

Wipe data factory reset, cache, dalvik.

Go into mounts and storage and format /system

Flash ROM

Flash gapps

Reboot

After that you'll be clean. Cleanest install ever.

HDR photography using SGS3 and CM10

Has anyone figured out how to take HDR photos, or just even change the exposure when taking photos using the SGS3 using CM10?

I'm running the 11/8 build at the moment and using the stock camera app, but none of the previous builds I've installed so far (going all the way back to August) seem to be able to change the exposure of photos. The stock camera app from 4.2 doesn't seem to do it either.

I previously used the "Pro HDR Camera" app to take HDR photos, but that app doesn't seem to be able to change the exposure either. It seems to me it's a driver/kernel type issue and there doesn't seem to be much mention of it anywhere on these forums of people being able to change the exposure of photos.

Can anyone shed some light on this? (hahaha)

CM10 Issues

Hi all. I'm running CM10 (cm-10.0.0-d2att.zip) and loving this ROM for the most part!

Does Name Display (CNAP) work for anyone? The name on a phonecall from a person who's NOT in my contact list shows up as garbled text. I read that this is a problem for some with other devices but wasn't sure if anyone else was having this problem.

Also, the "Bluetooth-not-reconnecting-to-car-audio-system" error isn't exclusive to car audio systems; I have that problem with my Jawbone ERA headset and have to use the same workaround of turning off and on Bluetooth for it to reconnect. Hopefully that gets resolved soon.

There's a sort of *workaround* you can try to fix it..

Turn on BT on your phone & (I'm assuming) headphones

Start playing your music/audio

Go to the phone, dial 611 and send till it dials and hang up.

It's not so much an app question--I'm mainly wondering if people can even change the exposure of photos using the stock camera app.

Majingrim, are you saying that you're able to take HDR pictures? If so, can you change the exposure when using the stock camera app? Which build of CM10 are you running?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Saint Wacko:
Just started using cm10 on my new gs3. Was the ability to change the brightness by swiping across the status bar removed in cm10? That was one of my favorite features in cm9.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] majingrim:
I just tried the stock camera, and it didn't seem to be changing exposures, but HDR Camera+ seems to. I'm definitely no camera expert though, so maybe that's not what's happening. But it's definitely getting brighter, then darker while taking the picture. I'm on today's build (11/19), but I've been using the camera on and off for the last few weeks. Hope this helps.
