BlackBerry® Curve™

[RONDARYL]

I have a Curve 8330. Recently (within the past 30 days) I was asked to upgrade the software via text and upgraded to 4.5.0.175.  Since this time, I have no ring tones/no audio.  I have heard that downgrading to the previous version will fix it but I can't seem to find the way to downgrade the device.  There appears to be no downgrade button in the device Options/Advanced Applications/wireless update area.  I am at a loss.  I have a 3.4.0.55 platform and I wonder if that is the problem.

Hi and welcome to the forums!!!! 

Here is the process for reloading the OS (the one you want to downgrade to) onto your device:

1. Get a good backup of your device: BB device backup (I keep all my backups in a separate folder created for that purpose so they are always in one place and easy to find.)

2. Download the most recent version of device software for your carrier: Downloading BB device software

3. Reinstall the device software: Clean reload of device software

4. Pull the battery out with the device ON. Wait about a minute and put the battery back in. Let the BB completely restart.

5. Once you have the device OS successfully installed you will then need to reinstall any 3rd party apps you currently have on your device: Install applications using the app loader tool

6. Complete another battery pull routine after each 3rd party app installation to reclaim memory and refresh your BB.

Let us know how it goes.

My blackberry curve has the same problem. The person on the other end can hear me, but i can't hear him/her.

One thing i found out is i can get the audio to work again if i toggle between handset audio and speaker phone. But this is kind of annoying as every couple minutes or so, when there is no audio (can't tell whether the other party has nothing to say or the audio fails again), i would then say, "hold on for a minute". I then toggle to speaker phone/handset, and say "can you hear me".

I would think this is software issue, but who knows.

My phone warranty last only one year (according to AT&T). So, if this is hardware issue, i'm out of luck.

If this is software issue, Blackberry support team won't talk to me to troubleshoot the issue unless i give them my credit card number and let them charge for using their time to troubleshoot their problem.

Not very happy with my phone now.

Hi and welcome to the forums wkwok!

A couple of places for you to visit: Blackberry 101    Tips & Tricks

Any other anomalous behaviour in your device?  Let us know.  You may want to reload your device OS.  See my message #22 above.

Happy to have you here!

Thanks for quick response, IrwinII.

I'm trying it now.

I did try the "Wipe Handhell" option as told by at&t support, with no luck.

Just finished reloading the device OS. Still no luck. I still need to depend on using Activate Handset/Activate Speakerphone if i want to hear what the other caller's voice.

I just don't understand why a software switch like that would temporarily fix a hardware problem.

Another thing, if i use a bluetooth headset, it seems to work fine. It's like only the handset's audio not working (including speakerphone).

[IrwinII]

Sounds like you may have a hardware issue.

Look at this thread and run the test suggested by Bifocals in msg 7:  http://supportforums.blackberry.com/t5/BlackBerry-Curve-BlackBerry-8300/Blackberry-Curve-8330-No-vol...

Let us know what you find out on the speaker test.

[wkwok]

I tried this a while back when i first found the problem. I hate to say this but the test is not that useful.

In a perfect world (in which we don't live), the phone would run some test and tell you what features or components are working, what are not working.

In our world, my Blackberry Curve ran some tests (activating handset audio, headset, speakerphone etc), then ask me whether i can hear the sound. Then based on my answers to its questions, it then tells me whether the test passed or failed.

Well, I don't need to run the test to tell the handset, headset and speakerphone audio are failing when i can no longer hear from the other end. And since the problem is intermittent, the tests would pass when my phone's audio is working and vice versa. Again, this means not much to me as after 5 minutes after it passed the test, i got no audio again.

Does it make sense?

[IrwinII]

I understand your frustration.  I've been seeing multiple instances of this issue and they seem to be coming from an OS upgrade the users received OTA from their carrier.  Who is your carrier, BTW?

When you reloaded the OS, did you reload the last one you received.  Try reload again, but downgrade to the previous OS you were using.  Since your problem seems to have come post upgrade, try moving back to the OS you were using before the upgrade and see if that corrects the issue.   There may be a problem with the "pushed" upgrade.

No worries.  You can always upgrade to a newer OS once your device if functining correctly again.

Let us know.

I downloaded it from Blackberry's website. Carrier is at&t.

I could try downgrading the OS.

But, i did the upgrade a long time ago; almost right after OS 4.5 was first available for at&t users. Hasn't had any problem until recentnly.

If it's an OS problem, i would expect a patch available rather than rolling back the OS on my phone. Besides, i would think the backup i did for OS 4.5 won't restore properly on OS 4.0, (the opposite way may have a better chance to work).
