Bluetooth issues - myTouch 4G Q&A, Help & Troubleshooting

I have been playing around with some of the custom roms and have somehow lost the ability to use bluetooth. I have tried re-installing CM7, royal ginger, and restoring to the backup I had right after rooting. The problem still persists. It is making me think that it may be a Kernel problem. Is there a stock Kernel somewhere?
Also before it comes up I have put my devices in pairing mode and still no luck.

CM --> MIUI --> CM Bluetooth Dies!

Hi folks,
I tried out the MIUI ROM and liked it, but for various reasons, I wanted to go back to CMod again. So, I restored my NAND backup of my CM6 install. When I did this, I noticed that Bluetooth was no longer working correctly, i.e. it would pair successfully with my radio, but it failed to connect to it.
When I restored my MIUI backup, bluetooth worked again.
I cleared every cache known to man and once more returned to my CM backup, but once again my Bluetooth failed to work.
In the end, the only thing that seemed to fix the problem was wipe all the settings (again) and flash the latest CM nightlies (very nice btw!). After this, all was well.
I am attaching a logcat file if anybody is interested in the Bluetooth output. My totally uniformed suspicion is that it had something to do with the way MIUI uses the Bluetooth stack to get the radio working, but I'm sure somebody out there knows better than I do.

[Q] Issues with Bluetooth and WiFi

So here's my story of what's going on and hopefully a solution can come out of it.
Got my phone used it for a bit. I used the root and debloat found here: http://forum.xda-developers.com/showthread.php?t=2282367 and everything went fine. Waited a day or so and decided to flash LiquidSmooth ROM with KToonzes 7.2.13 . Again everything working fine. I then flashed 7.7.13 Ktoonzes and lost bluetooth functionality as far as the phone is concerned but the music portion is fine. My brother convinced me that the Google Edition ROM is where its at and I was having that bluetooth issue so why not. I flashed the AOSP Ktoonzes instead of the TW so my phone bricked. I did the ODIN back to stock with: http://forum.xda-developers.com/showthread.php?t=2261573&highlight=odin . When that went through and my phone was doing its set up, my wifi wasn't turning on. I continued by using the root and debloat again to reinstall the recovery. I recovered my phone to right before I flashed the Google Edition, and my bluetooth is not even finding my car in pairing mode at all at this point.
Thanks for reading and thanks in advance for any recommendations to fix this issue.

[Q] Wifi broken, can't seem to fix it

Hiya,
Using the international i9505 LTE, I tried flashing faux's kernel today, and everything appeared to be working. I also then flashed the xposed framework/some modules. Afterwards, I realised my wifi wasn't working anymore, and disabling the xposed framework didn't help. I also tried flashing the ausdim kernel which didn't work, as well as flashing my modem file, and the apparent wifi fix files multiple times, none of which solved the problem.
I have a nandroid backup, but would rather not restore it atm as it was made a while ago and I don't want to restore all the apps and stuff, so does anyone have any idea how to go about solving this problem?

Basically yesterday I had the same problem, flash after flash didn't help. Can tell you exactly, what I did:
Found factory version of my firmware in my region (SEB Baltics for me, MGA). Then I reinstalled TWRP recovery through ODIN, wiped everything I could, after that flashed stock firmware 2 times consecutively (no reboot in odin, reboot manually after first flash and flash again).
After that everything went fine, and Wi-Fi started working again. MH1 custom ROM right now, going ok.
Googling seems to suggest having to reflash stuff multiple times (I've seen someone say they flashed their stock rom 11 times wtf), and there doesn't seem to be any set procedure that gets the flash to work... Did you also flash multiple times before this last run worked? Perhaps you just got lucky and it worked the last time? (I assume no one tries to bork their wifi and test if their last routine works again for them).
I'm asking mainly because I don't want to go through the hassle of reflashing the entire rom again; would it be correct to say that wifi is just contained in the modem/radio file, and I should try spam flashing that?
No. WiFi drivers are in the kernel, not the modem. If you were going to flash anything, you'd flash a kernel/rom.

I suggest you use titanium backup to bakup your apps, it's not a tough job as you thought. that might be the easiest way, although some data can't be backup.

No, I did flash it 2 times straight away. Flashing correct modem didnt help me, dunno why.

Welp, bluetooth had no problems whatsoever. It was only the wifi, which didn't want to turn on. Now everything is ok.
Well, finally got around to reflashing stock as Gh0stR1pp3r suggested, which worked. Thanks
Nandroid, kernel flashing, and modem flashing all didn't work. No clue why. I flashed the ausdim kernel again and it worked this time around, so it's just weird I guess? :S
And unfortunately I seem to have messed up the titanium backup somehow, I can't seem to find any of the stuff I thought I backed up Oh well

[Q] Problems with audio after flashing MGG

Hi!
I flashed a rom with MGG and got the same FC problems as everyone else. Flashed the stock MGG rom and cleared everything, factory reset etc. After that I didn't get any audio at all. Not ever during the samsung bootup animation.
I flashed another rom through cwm, same thing and no wifi. The wifi fix doesn't seems to work either.
Tried CM 10.2, there I'm getting wifi but instead no data trafic. Baseband says "unknown" even through I flash different modems. The wifi and data problems I can get around, its just that I can't flash older roms through odin until they unlock the new bootloader.
The audio problems in the other hand. Saw some guy having sound problems in the modem thread as well. Not to many have posted about this problem. Seems to be a pretty rare problem.
What could cause this, how to get around this?
Had to go to work with a non working phone so can't get any logs for you at the moment.
I'm concerned, please enlighten me!
Finally, flashed the latest CM 10.2. Got wifi and reception working!
Still no sound. What log would you like to see to find out what's wrong?

[Q] i9505, no sound, DSP Manager crashing

Hi
My device baseband is I9505XXUEMK9, Android version 4.3.1, and on a custom ROM (Slimbean).
The issue began when I attempted to flash a 4.4.2 (official) stock ROM from another country, which I now acknowledge as a MAJOR mistake. It was unsuccessful and led to my phone being soft-bricked. However, I had backed up my device prior to flashing 4.4.2 so that ensured its functionality.
After restoring my phone using the backup, the phone completely lost sound output. Whenever I tried to play music, the message "Unfortunately, DSP Manager has stopped" pops up. Video and audio cannot be played at all so apps like YouTube, alarm clocks, PVStar, and video-sharing websites would either crash or provide no video/audio output.
I can make calls but they result in a laggy black screen and there is no sound. I can only receive messages that calls have been missed.
I have tried flashing official stock ROM (I9505XXUEMK9) various times but they all resulted in failure. I have also flashed the modem for my device (XXUEMK9). I have tried out different custom ROM's but the problem persists.
Is this situation salvageable? I am willing to school myself on bootloaders and the such to solve this issue.
Help is much appreciated.

I would do a full wipe from Philz Touch CWM. Clean to install new ROM, and after that recover Your backup.
If it wont work, dirty reflash your Slimbean.
If it wont work, backup Your sdcard, install stock recovery or prerooted stock rom and wipe Your phone from there. If Odin wont work, try Mobile Odin.
Thank you for the response.
I have tried the first and second methods, yet the issues remain.
I am going to try the third one though it would be using a prerooted stock ROM of another variant as there are no XXUEMK9 prerooted stock ROM's.
EDIT: Third method didn't work for me either. It yields the same result as flashing the official stock ROM's.
