Root Bluetooth woes

Hello,

I unlocked my Spec, only to then realize that doing so borks the bluetooth. Is there anyway to get the old kernel back besides pushing the v7 .cab file? I don't mind losing the unlocked bootloader, I really don't want to reset all my data again!

Thanks in advance!

Pushing the .cab doesn't actually seem to effect data, at least it didn't for me last time I used it.
 
That's good to know! Any way to do it through CWM? I'm at work now and cannot install the drivers to us the LG tool.
 
glad its not just me having the issue. i'll have to try pushing the .cab without wiping my data to see if it will stick. I initially thought it was because i was restoring files with TiB but thats not the case apparently. even with a fresh install it would stop working and i cant restore to a stock version with working bluetooth cause it stops working too.
 
Just went through same thing...
Im a otr truck driver, n bluetooth is a must...
I pushed v7 today, isnt hard, but when i did, bluetooth till didnt work.

Blutooth said it was conected, but phone said passkey/pinn was wrong.
N it didnt give ANY OPTION to reset it or enter a new one.

Finally found reset hole on blutooth, stuck staple in n reset it...

Edit
When pushing, make sure ya extract when it said extract, n move when said move.

I so use to extracting, i extracted both(kp500 n .cab file)... but i re read instructions bout 5times, n realized what i did
 
Figured I would give an update. I pushed the stock v7 cab using the K500 program. It fixed the issues with the bluetooth without clearing my data. Granted the bootloader is locked again, but BT is more important to me than the bootloader.
 
I too can confirm this as well. rooting has no effect on BT either, but as soon as you unlock the bootloader and flash the custom kernal, BT gets broken
 
Possibly the best reply ever /\
Now every time I think of LG I'm going to imagine them horsey dancing

When lg gets the kernel source posted, I'm hopeful that will let us fix Bluetooth. Right now they are too busy dancing gangnam style to be bothered with trivial things like licencing compliance.

Just an FYI, I contacted Free Software Foundation, Inc in regards to LG's apparent disregard for the kernel source code which is licensed under the GNU GPLv2. I'm waiting on a response. Even if this doesn't get LG in trouble, the goal was to light that fire beneath their ass to get them going. Shouldn't be too long of a wait on a response from the Free Software Foundation. They tend to act fast on stuff like this. I'll post back once I get a response.

I compared kernel sources from P930 Nitro and Spec(official 3.0.8), and found differences in sdio_dmux.c. That differences was remarked as:
"// ALRAN QCT_Patch 20120531 bluetooth.kang".
Don't even know if this related to the bluetooth problem at all, but I have attached diff.

Interestingly, I just made a Bluetooth call from my nitro earlier this evening and the audio was busted. The kernel I'm using is from an official cm10 build. Hmmm...

I have compared both kernels from LG, official 3.0.8.

upd: I compared only mach-msm, not entire tree.
Only one additional difference, in tables at acpuclock-8x60.c

upd2: at cyanogen they already updated to patched version. But the forked version is not.
