[SOLVED] help! Can't enable bluetooth

---

EDIT: SOLVED!!!! it was a usb brick. see last post for details.

hi all,
I have a problem with my desire.

Bluetooth won't turn on. If I try to enable BT, it says grey'ed out for like 10 secs and the goes back to unchecked.

I got this device used so I don't have many background information. All I can tell is I tried different ROMs and wiped all I could, but still no luck. I actually highly suspect this might be an hardware issues, but I'd really like to try everything before shipping back to assistance.

Here are my current specs:

htc desire amoled
bravo pvt1 ship s-on

hboot 0.80.0000
radio 5.11.05.27

rom cyanogenmod 7.1.0
kernel 2.6.37.6-cyanogenmod-geb50077

Recovery: Clockworkmod


ANY hint highly appreciated.

Got exactly the same problem.

BT worked while running the former stable CM release. I first noticed this issue when flashing latest CM. You tried other ROMs which didnt work?

Did you try other Radios as well?

I am not an expert, but I think it could be a problem of the radio. I never totally understood what the radio does, so could anybody help with this guess? I never changed Radio as there was no need for (never touch a running system).

lexo, did you try rolling back to 7.0.3 to see if BT would work again?

I was also thinking about radio, exp b\c it seems to not be a ROM-specific issue, as I have tried several: LeeDroid, InsertCoin, MIUI, as well as a stock rom.

I believe the point with radio is not necessarily about having the latest, but finding the one that works well with one's rom. Also, there is RIL, but that I don't know what it does.

No, didnt try that yet.

I use BT in my car to listen to music only so I didnt notice the issue at first. Now i am thinking about buying Galaxy Nexus, so I am not too exited about that point. But as I am willing to pass my Desire to my lil sister I would love to have it fixed.

Whats "RIL"? Think I never heard about it.

Don't know if this is relevant but had a similar problem with Bluetooth, wifi and Mobile data yesterday. None of them had connectivity!

The remedy that worked for me was to wipe the cache and dalvik, reflash CM7.1 via recovery (but remember to also flash the Google apps package) and soft reset.

No data is lost this way.

Hope that helps!

so far I did:
- wiped everything including dalvik and reflashed cm7 - no luck
- removed files in etc/bluetooth [read somewhere] - nuthing
- applyied a .zip update that is supposed to fix a possible USB brick - no change.

@LEXO: I think you might try the first two things I did, in your case they might work.

So now I flashed a RUU Rom and reverted to stock s-on bootloader, hboot, radio (ril, too, I believe, though I dunno how to tell ril version) and recovery.

The only thing I'm not completely sure about is the USB brick fix, but otherwise it's ready to ship to assistance.

@Reaper, can you point me to the USB fix you referred to?

guys!!! Thanks everyone, expecially reaper.
My BT is working again!!! turn out it was a USB brick, which I was able to solve fairly easy.


I had tried a usb brick fix that involved flashing a .zip, which I did. However still no BT changed so I assumed phone was not bricked after all.
Also, I always assumed usb brick would involve major cd and usb connect malfunctions, and that was not my case at all.

However it must have been that fix that didn't work, because I then followed the guide on this forum http://forum.xda-developers.com/show....php?t=691639: got my CID via fastboot, modified the files accordingly, put them on sd card, got temp root with visionary, issued the necessary commands with "free root system tool" terminal, rebooted, and voilà! BT is finally green.
I can't believe I made it!
