Re: Trackpad freezes BB 8520

Well I got a curve.8530 with a track pad and from what I see so far its only 8520's. If anyone with an 8530 has this freezing problem, reply to this post please.

You may have to open and replace the trackpad.. If it does not work then the chip that controls that data needs to be reflowed or replaced by a technician.

There are several ways your trackpad will stop working;
1. Corrosion
2. Phone flexing.. What's this? People having there phone in there pockets constantly applying pressure and bending the phone.
3. Incorrect firmware flashing
4. System connector has cold solder
5. Micro chip that controls the trackpad has cold solder

How to fix this PRB?
1. Flash your phone till you have no choice to take it to a tech..
2. Replace the trackpad
3. Qualified Technician must Reflow the system connector or the Chip

Water damage phones don't apply.. your screwed. sorry.. Corrosion is a cancer to phones. It always comes back... It's only a Temp fix..

I made a easy schematic of the trackpad connector pinouts..

SAY Thanks.... Ciao I hope it helps you...

Re: Trackpad freezes BB 8520

I have exactly the same problem in a 1 month old Balckberry Curve 3G. Carrier: Movistar. I've been a Blackberry fun during 7 years but I'm thinking to switch to iPhone due to this annoying problem.

Re: Trackpad freezes BB 8520

I have the curve 8520 and have had it for atleast 2 years. Nothing has ever gone wrong with, maybe just a bit of cosmetic damage. But yesterday my trackpad started spazing out. I rebooted my phone and I wasn't working at all. I would say that you might as well replace the trackpad. Will I will do as I'm waiting for it from eBay. But it annoyed me so much I went out and got the new Torch 9810.

Re: Trackpad freezes BB 8520

Had this with my bb8520, tried everything, rebooting soft/hard/every which way - but found that after taking the battery out and pressing the shiny metal plate behind the sim card a few times, it's working again fine.....we'll see!! Must be a contact issue.....take note manufacturer/s!!

Re: Trackpad freezes BB 8520

Yeah. I took out the battery and pressed that metal plate. Shame I wasted £2 on a new trackpad from eBay. But hey its not much. And I much prefer my Torch 9810. But anyone who has this problem I recomend you try this first. If not then try calling Blackberry or just fix it your self.

Re: Trackpad freezes BB 8520

After pressing the metal plate you should follow these steps which will work like a charm.

Go to Options>Screen/Keyboard  and set the trackpad horizontal & vertical sensitivity to 30.

Re: Trackpad freezes BB 8520

Makes one wonder if the freezing trackpads are not because you bought a refurbished device. I know that the refurbished devices are only suppose to be when a new device is being replaced, they send you a refurbished one but I have a friend that swears he bought a device from a retailer and somehow found out it was in fact refurbished. I absolutely refuse to recycle any cell device. I bought my 8530 and 2 months later the recharge jack was a lot too loose and was sent a refurbished device for the new one I had just purchased... Shame one your warranty policies... I could understand it if I had already used my device for nearly a year but 2 months??? Come on!!! I felt scammed...
