[Q] FFC not working - Thunderbolt Q&A, Help & Troubleshooting

I rooted my phone a few months ago and now, no matter what ROM I flash onto my phone, the front-facing camera doesn't work. Every time I open the camera app and click the button to switch cameras, the camera app closes because for some reason, it's not detecting the FFC. I was thinking about unrooting my phone to see if the FFC camera works when unrooted, but that's a big hassle. Anyone have any other suggestions?

You could try unrooting. There is a new tool in the development section, thunderbolt tools that has everything you need to root and unroot pretty quickly. Maybe try that and see if it works. Do you have a nandroid of stock to flash back to?

I'm gonna sound dumb asking this, but what example do you mean by "nandroid of stock"?

I also forgot to add that my phone is the Thunderbolt.

Camera could also be dead (hardware wise). My back camera is dead, showing only a black screen or force closing no matter the app or the rom I have tried. But the FFC works fine for apps that can start into it automatically (video chat apps).

No dumb questions my friend lol. If you are rooted, did you make a backup of your of your stock Rom through clockword mod or whatever recovery you may have?

I hope that's not the case for me. I don't wanna have to replace my phone since I'd have to pay full price now.

Also, I'm not sure if anyone has experience using the Thunderbolt Tools thing they posted in the development page, but I'm trying to use it to unroot my phone and it keeps giving me the same error message. It keeps giving me this when pushing the stock files to my SD card:
"failed to copy 'support_files\unroot\Stock-ROM.zip' to '/sdcard/PG05IMG.zip': Read-only file system"
Anyone know what to do?

Sounds to me like your sd card is set to read only.

Has anyone else encountered or solved this problem? When I try switching to FFC (no matter which app or version of the camera app I use), the camera makes a low clicking noise, then the app closes (no error message, no force-close window -- just closes and I'm back at the home screen). I have tried clearing cache, changing the system date, wiping cache, wiping data, mecha-superwipe, factory reset, different ROMs -- including CM7, Das BAMF, the new BAMF ICS leak. The only thing I can think of that I have not tried is unrooting. Anyone have any ideas -- or does this absolutely sound like a hardware issue?

[Q] Please Help!! USB mode is not turning off!!! Couldnt find help in other forums!!!

Hi All,
I am very sorry if I am posting to the wrong forum. But I couldnt find answers in any others. PLease HELP! My USB mode is always turned on. It always says its charging even if not connected to PC. Because of this my battery always shows 100%. I have a rooted stock ROM. I just did the OTA update. But this problem happened before the TMO OTA update. PLease let me know if you have any suggestions!!
I will be very grateful for your help!!!

Yeah it's definitely winamp. I had it installed and had the same issue. Instantly disappeared as soon as I uninstalled it.
It is a feature of Winamp. The automount may be toggled on/off from inside Winamp's settings.

Check in your About Phone and make sure you did get the JI6 update. That was supposed to fix the "known Issue" when i was talking with the tech support at TMO. Of course, i was running a third party rom and couldn't get the update so i flashed Bionix 1.9.1 which had the update built in and have been good since. If that doesn't work or if you DO have the update and still having the issue have them send a replacement as it is a defect and they will send a new one.
I had to exchange my phone, tmobile explained to me that its an issue with some phones and cannot be fixed so they sent me a replacement phone. I would one click unroot and exchange your phone. That is what I had to do.
Hi.. Thank you all for your response.. Is it possible to fix it if I flash it with a new ROM? Or is it becuse of hardware issue? I am waiting for a Froyo ROM to flash it. Would it fix the problem?
Thanks

Wow I wish my battery was that good...
Try repartitioning with stock ROM in ODIN. It seems to solve a lot of issues, but it will wipe your internal SD.
I have this same problem and I have had no luck fixing it with ANYTHING! I tried ODIN so many times and its always the same issue...
Moved to Q&A.
any body have fix usb connected ?
i've done all which is writes around the internernet after reading 400+ web site threads/posts still not able to solve, Please if anybody have done please share with us

[Q] do you have strange clicking sound on the back?

Hello im getting a strange clicking sound on back of the phone, close to camera, im getting it wen i do factory reset and on the first menu it does that, and in Camera app when you change picture to movie and so on... Does any one else experience it?
It`s been reported in a few thread , some camera make the sound and some don't , it might be a different make or firmware version.
It`s just the camera focusing in the camera app, it also happens when you power up the phone, it`s initialising the camera.
Is camera focusing ok, have you tried it with close up object how close can you go.
Just to make sure it`s ok
I also notice that when i tilt device to landscape mode i have to wait about 3-4 sec... i dont think thats normal.

I'm sorry I don't have an answer for you. I'm experiencing almost the same thing, except I get a camera fail message every time I open the camera. I've posted in other forums here and haven't gotten any help.
Guys I am here to help you lol I had this problem and the answer is clear data and cache for the camera in roottoolbox . And if that didn't work(like me) them your camera is malfunctioned and you need to send it in to Samsung toq get it fixed. I think they are out of vibrant though

I havent tried clearing data or cache. But i installed a replacement camera, and it worked for a day.. then I got the camera fail message. I even flashed back to stock and still no luck.
Same problem. Only fix is banging the camera side on a hard edge a couple times. It removes the camera failed for a bit. Although it can't be good for the phone. Im guessing its a bad connection between the camera module and the computer.

Is My Atrix SLOWLY Bricking??

about a month ago this happend to me:
out of the blue everything on my phone started FC repeatedly (whatsapp, camera, Luancher Pro, phone, etc..) so pulled out the battery and it then it didnt want to boot up so i tried a fresh install from recovery but.. recovery was crashing as well and i had to pull out the battery every time. finally afer playing a speed game with the phone i got to re install (i wiped user chache/data /dalvik ) and the problem was gone ...
these recent days some apps started FC on me but i thought i was somewhat common .. mainly Mi file explorer .. so right now my phone started to do the same thing again.. FC everything! The main one crashing is = the process com.android.phone stopped unexpectedly. i have no signal now and cant open anything.. if i pull out battery I know it wont boot up and may not let me use recovery without a hassle!
i dont know if this has to do with but when i install a rom ( i had topsmarts 1.3) i use root uninstaller to uninstall lots things i dont want like: weather and news, terminal emulater, dev tools, es explorer..
what is can be causing this problem and what can i do to fix it??? it looks like i wont be using it today because its as good as a brick right now.
edit before OP: i selected reboot and as expected its looping at the Unlocked screen:crying:
Try re-flashing it anyway... if there's a recovery problem again let us know

It's not a living thing or a machine with mechanics that suddenly doesn't work because of a misconception. If it was a misconception it would not work at all. If you solved it by reflashing, then it's a software issue and it won't happen again if your CWM image is not broken. But just to make sure I would reflash CWM to make sure it doesn't cause any trouble.
and be careful with removing system apps
Sent from my MB860 using xda app-developers app
I believe it was you removing system apps which caused your problems. You should always freeze system apps instead of uninstalling/removing them. That way if your phone starts to act up you can thaw/unfreeze them until you figure out which one is causing the issue.

Exactly. Removing system apps can result in accidental removal of base code and intrinsic system processes that are required for your ROM to function properly. These apps can probably be disabled and hidden instead of removing them altogether.

A logcat would help tremendously here. Would show exactly why things are FCing.
sorry i dont know how to do a logcat .. but the things i remove are:
es file explorer
news and weather

You really have to freeze apps one by one if you are unsure of what you are doing. On stock Blur build for example, Yahoo Authenticator can cause FC issues with your contacts if you freeze or delete it. You wouldn't think this would affect your contacts, but it does.

"Super Clean Wipe" or something like that

Hi people.....w/o long disortation...
Isnt somewhere out there a super clean wipe... (not odin) that some devs suggest that we use b4 flashing. ..just to get a clean slate....
I believe I need that...bc I am using a rom ported from an international rom...and gps is speculative. I basically dont have gps lock (it locks and then somehow it looses its lock..and through some marvelous people helping we think I am not getting a complete wipe...via twrp... (tried everything)...so thats why I am asking for this "super clean wipe" or something like that. ..
I know there was one for the Verizon Gnex

Use FasterGPS to change the gps.conf back to the US. It is fairly straightforward to use, just give it root privileges then:
1. Under continent select North America
2. Once you select continent the Region box will become selectable, you need to choose United States.
It will show a toast message that says the GPS.conf was written successfully, then you just need to load Maps up and it should lock on quickly without losing the signal.
If that doesn't work just post back and I will give you something else to try because AFAIK the Super, Mega, and whatever the hell wipes aren't recommended for this phone and if I am remembering correctly they caused soft bricking on our phones that was a ***** to fix. While this wipes have most likely been fixed I wouldn't bother with them, if you want to do a wipe because what I told you to do doesn't work then you just need to boot into TWRP, click wipe, click the box on the right side (I think its format data or something but I can't remember off the top of my head), type yes, click go and then reflash whatever you want. At least try FasterGPS first, that works most of the time on International Roms.

With this fix you don't have to push anything at all, just boot into recovery and flash it like you would a ROM. Don't bother wiping anything with this fix, just flash it.
http://db.tt/9E3aMJxS
Also pushing files isn't that bad when you use something like Root Explorer, all you have to do is copy and paste it to wherever it needs to be. If you have to fix the permissions after pushing it you just have to long press and change them, it will load a little box with all the permissions and all you have to do is check the ones needed.

What the hell? There was a report of that in the thread in General but I figured it was bogus because the person would never ever reply and every single ROM I have tried it on, TW included, it either fixed or did nothing.
When you restore your nandroid does your GPS go back to the normal non working state?
Something else you could try, that i just thought of when replying to someone in the VRB thread, is making a nandroid of a TW ROM, that you got a strong GPS lock for at least 5 minutes, on your internal SD and then try either reflashing Moon or restoring a nandroid of it. I would probably just reflash it to have a clean slate but I would also understand if you didn't want to have to go through setting it up again.
That probably won't work but I know on my S3 I had to have a working backup on my internal or else GPS refused to work at all, on my Note 2 I have to reflash the fix I linked above if I forget and wipe my nandroid before establishing a lock.
Also are you trying to get a GPS lock with or without the Wireless network setting on? I know on AOSP having the WiFi and Mobile network location setting checked in addition to the regular GPS location it would refuse to even turn the GPS on. You had to have the wireless location setting off before you could get your GPS to work, while this isn't AOSP it could be a shared bug and is worth testing out.

For my Thunderbolt there was a file called "SuperWipe" that was essentially a blank file system that you could flash to your phone to quickly clear EVERYTHING.
I have not seen anything like that for the Note II yet.

It was released right after the phone came out. I want to say it was released in the N7105 forums, it could have been AT&T though, and there were some serious issues it was causing in all the Note 2's. It was supposed to have been worked on but I haven't heard anything since then and honestly wouldn't use it after all the corruption issues that arose from it.

That is the way i have always done it, on CleanROM ACE 4.9, Vanilla Rootbox, and all the other miscellaneous TW and AOSP ROMs I've used it on. It is made for AOSP but didn't hurt any of the TW ROMs I've rested it on.
If it completely got rid of your GPS when you tested it before though it may just not be a good idea to use it on Moon.
When you're testing GPS do you always have the WiFi and Mobile Network Location seeing under Location Settings checked? I know on AOSP for a while you couldn't use that setting at all and then on some TW ROMs you had to use it to get your first lock and after that you could get away with not having it enabled.
I would just flash Moon ROM and see if you can get a lock. Try it after creating a nandroid of a TW ROM that has working GPS on your internal storage, on my S3 the only way I could get a lock on any ROM was to keep a nandroid with working GPS on my internal SD card.
