Please help me to rework my blackberry curve. Help Translate iFixit. BlackBerry Curve Troubleshooting. Edit Options History. An issue I ran into was that, I did not know the value of the damaged capacitor. But generally, between 10 uF to uF capacitors is used for power line filtering. The only SMD capacitor I had close to the size of the damaged capacitor was size , 4.

Having something there is better than having nothing. And since there was enough space to safely solder this size, I decided to use it. Prior to re-soldering the new capacitor, add a tiny bead of solder to the existing solder pad. This can be done with a normal fine soldering iron if you are using solder wire. Else, a tiny drop of solder paste will do. If it indicates a short after soldering, you may have created a solder bridge. Add a dab of flux to ease solder flow and reheat the component. Once you are done and there is no short circuit indication, pop in the battery and test the phone.

Request: If anyone knows the exact value of the damaged capacitor for this phone model, kindly post in the comment section.

Thank you. Once you are happy with everything, re-assemble your phone.

This step is just the reverse of the disassembly process and is pretty straight forward. Just make sure you do align and plug in the connectors properly. If it does not go in fairly easily, do not exert excessive force.

Unclip, align and try again. Again, do not use excessive force on the plastic parts as they have clips which may break and DO NOT over tighten the screws. This is a simple fix as all you need to do is a system restore using Blackberry desktop manager. When I connected the phone to my laptop, Blackberry desktop manager displayed a communication error message and prompted an update, which I followed. When I clicked 'Get update' however, I got an error message and everything cancels. After flashing and reassembling the phone, the flash LED would light up upon inserting the battery and stay on even if the phone was turned off.

Turns out it was a bug in the firmware. So I re-flashed the phone with the latest firmware and that did it after a few hours. After re-flashing the phone, the flash LED would still be on but fluctuating. I left the phone on a table for a few hours and sure enough, it went back to normal. Note: - Should you have any questions, please feel free to ask.
